The Safety and Efficacy of Ferumoxytol in the Treatment of Iron Deficiency: A Systematic Review and Meta-Analysis

BackgroundIron deficiency (ID) is one of the most common nutritional deficiencies worldwide, with an increased prevalence in pathological states such as end stage renal disease and inflammatory bowel disorders. Iron stores can be replenished by either oral or intravenous (IV) formulations, however IV formulations are known to raise iron stores more quickly and reliably. Ferumoxytol is an IV iron formulation used in the treatment of ID that, advantageously, can be given in large doses over a short period of time. Despite the initial large quantity of post-marketing reports of serious adverse events (SAEs), multiple clinical trials have failed to demonstrate a significant safety signal.ObjectivesTo determine the safety and efficacy of ferumoxytol in the treatment of ID compared to other IV and oral iron formulations, and placebo.MethodsThis systematic review and meta-analysis was conducted following the Cochrane Handbook, and was reported as per Preferred Reporting for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.We searched the Cochrane Library, Medline, and EMBASE from inception until February 2018 as well as trial registries and reference lists of relevant articles.All randomized or quasi-randomized controlled trials comparing ferumoxytol to alternate IV iron, oral iron, or placebo were included. Outcomes included treatment emergent adverse events (TEAEs), treatment related adverse events (TRAEs), SAEs, related serious adverse events (RSAEs), hypotension or hypersensitivity reactions (HHR) and composite cardiovascular outcomes (CCO).Two review authors independently extracted data and assessed included studies for risk of bias. If required, additional data was sought from trial authors. Meta-analysis was performed using the Review Manager 5.3. Data was pooled using random-effects models. Risk of bias was assessed using the Cochrane Collaboration tool Risk of Bias. The GRADE approach was used to assess quality of evidence.ResultsThe review included nine studies, one of which was a cross-over trial. These included 5691 participants (mean age 54.3, study mean range 30 to 65.1 years). Ferumoxytol was compared to alternate IV iron in three studies, to oral iron in two, and to placebo in four. Overall, studies were at low risk of bias (see figure 1).There was high quality evidence that relative to other IV iron formulations, ferumoxytol has little to no increase in the achievement of a minimum 1g/dL increase in hemoglobin (Relative Risk [RR] 1.04, 95%Confidence Interval [CI] 0.96 to 1.12; 767 participants pooled (pp) from 2 trials)), low quality evidence that it has little to no decrease in TEAE (RR 0.88, 95%CI 0.80 to 0.97; 2764 pp from 3 trials), little to no decrease in TRAEs (RR 0.73, 95%CI 0.61 to 0.88; 2764 pp from 3 trials), little to no increase on SAEs (RR 1.13, 95%CI 0.77 to 1.67; 2764 pp from 3 trials), and little to no decrease in RSAEs (RR 0.58, 95%CI 0.13 to 2.55; 2764 pp from 3 trials), very low quality evidence that it has little to no decrease in HHR (RR 0.58, 95%CI 0.31 to 1.09; 2764 pp from 3 trials) and moderate quality evidence that it has little to no decrease on CCO (RR 0.56, 95% CI 0.24 to 1.29; 2602 pp from 2 trials).Compared to oral iron, ferumoxytol had less TEAEs (RR 0.78, 95%CI 0.61 to 0.98; 515 pp from 2 trials), but compared to placebo ferumoxytol had more (RR 1.62, 95%CI 1.01 to 2.61; 2348 pp from 3 trials).Publication bias was not assessed due to the limited number of studies included.ConclusionsUpon review of the available evidence, ferumoxytol is probably as efficacious as alternative IV iron formulations with no clear safety concerns. In addition, ferumoxytol had less TEAEs compared to oral iron formulations, but more compared to placebo.

Wednesday, September 26, 2018 7:35 AM–9:00 AM ePosters: P63. Pain-related safety outcomes seven years following lumbar total disc replacement in mobile core devices versus constrained core devices

BACKGROUND CONTEXT Total disc replacement (TDR) is an alterative to fusion for treating patients with disabling discogenic back pain. While several studies report significant improvements in overall back pain following TDR, some patients may experience recurring episodes of pain in the lumbar and/or lower extremities. Competing lumbar disc arthroplasty devices include a mobile core device versus a constrained core device. Long-term follow up (>7 years) from investigational device trials is now available to better assess long-term outcomes with arthroplasty with the two device types. PURPOSE To evaluate pain-related adverse events in patients 7years following single-level total disc replacement at L4–L5 or L5–S1 with either a mobile core disc (MCD) or a constrained core device (CCD) to determine if implant design is associated with increased pain serious adverse effects at 7-year follow-up. STUDY DESIGN/SETTING This post-hoc analysis of a multicenter, prospective, randomized, controlled, investigational device exemption trial included patients with symptomatic lumbar degenerative disc disease at L4–L5 or L5–S1. PATIENT SAMPLE The patients had lumbar arthroplasty surgery with either an MCD (n=218) or CCD (n=65) implant and were randomized prior to surgery in the IDE study. OUTCOME MEASURES The study reviewed events deemed to be serious adverse events in a FDA IDE study. METHODS This post-hoc analysis of a multicenter, prospective, randomized, controlled, investigational device exemption trial included patients with symptomatic lumbar degenerative disc disease at L4–L5 or L5–S1. Pain related adverse events (AE) at 7years post implantation for TDRs as a class and by device type (MCD vs. CCD) are reported. RESULTS Of the reported AEs, 23% (N=327) were categorized as pain of the lumbar and/or lower extremities: lumbar only (7%), lumbar and bilateral lower leg (5%), and lumbar and unilateral lower leg (3%). Patients presenting with AEs reported an average of two pain related AEs at 7years post-op. Of the pain related AEs, 11% were device related, 8% were procedure related and 9% were serious AEs (SAEs). Onset of the first pain related SAE occurred on average at 49days (range: 0–118 days) and 395days (range: 0–2,728 days) following CCD and MCD implantation, respectively (p=.21). Overall, the majority of pain related SAEs were classified as severe (69%). A greater proportion of patients implanted with the CCD device presented with severe SAEs (88%) compared to patients with MCD (61%; p=.17). At the 7-year follow-up, over half of the SAEs occurring in MCD patients were resolved (56%) while the SAEs in CCD patients remained mostly unresolved (75%; p=.14). CONCLUSIONS While the rate of pain related AEs were the same between patients implanted with an MCD or CCD implant, there were observed differences in the quality of SAEs between the two TDR devices. On average, the first pain related SAE in MCD patients occurred approximately 1 year after CCD patients. Furthermore, a smaller proportion of SAEs were severe and a greater proportion was resolved by the 7-year follow-up appointment with MCD versus CCD implanted patients.

Clinical and economic burden of serious adverse events (SAEs) in an early phase trials unit.

e18890 Background: With increasingly complex early phase trials and the need to closely monitor toxicities, management of SAEs is associated with substantial burden on research units. Detailed costs are often not captured and so not recovered from study sponsors. Methods: Data was prospectively captured on SAEs occurring in patients (pts) participating in early phase trials in the Drug Development Unit (DDU) at Royal Marsden Hospital/Institute of Cancer Research. Event, grade, investigations and management were documented. Time spent on SAEs by health professionals and operational staff was estimated. Costings were calculated using NIHR costing template. Results: Over 12 months, 50 SAEs were reported in 43pts enrolled on 50 trials; 17% of all pts treated (43/247) experienced 1 or more SAE. 88% of SAEs were hospitalizations, 10% medically important. 38% were assessed as study related (Investigational Medicinal Product (IMP) or study procedure related). Median length of hospital stay for study related SAEs was 3 (range 1-16). For study related SAEs all patients underwent clinical assessment and laboratory investigations; radiological imaging was required in 32%; specialist consults in 21%; and specialist tests/procedures in 21%. Median cost of managing each study-related SAE was £1630. Administrative time spent transcribing data on SAE forms was 46 hours over 12 months. Conclusions: Drug-associated costs may differ due to variations in pricing policies and health systems. This is the first comprehensive report of the substantial economic costs of managing SAEs in early phase trials. Accurate costings are necessary to allow costs to be shared with sponsors. Table: Study Related SAEs Non-Study Related SAEs SAE Category Hospitalization 30% (15/50) 58% (29/50) Life Threatening 2% (1/50) Medically Important 8% (4/50) 2% (1/50) SAE Associated Interventions Days hospitalized (median, range) 3 (1-16) 4 (1-26) Radiology (X-ray, CT, USS, MRI) 32% (6/19) 64% (20/31) Specialist consults 21% (4/19) 61% (19/31) Additional investigations/ procedures (e.g. bronchoscopy, ascitic/ pleural drain) 21% (4/19) 23% (7/31) SAE Associated Costs Total cost £63724 £156060 Cost/SAE (median, range) £1630 (£189- £10172) £3922 (£309 - £17689)

COMPARE CPM-RMI Trial: Intramyocardial Transplantation of Autologous Bone Marrow-Derived CD133+ Cells and MNCs during CABG in Patients with Recent MI: A Phase II/III, Multicenter, Placebo-Controlled, Randomized, Double-Blind Clinical Trial.

Objective:The regenerative potential of bone marrow-derived mononuclear cells (MNCs) and CD133+ stem cells in the heart varies in terms of their pro-angiogenic effects. This phase II/III, multicenter and double-blind trial is designed to compare the functional effects of intramyocardial autologous transplantation of both cell types and placebo in patients with recent myocardial infarction (RMI) post-coronary artery bypass graft.Materials and Methods:This was a phase II/III, randomized, double-blind, placebo-controlled trial COMPARE CPM-RMI (CD133, Placebo, MNCs - recent myocardial infarction) conducted in accordance with the Declaration of Helsinki that assessed the safety and efficacy of CD133 and MNCs compared to placebo in patients with RMI. We randomly assigned 77 eligible RMI patients selected from 5 hospitals to receive CD133+ cells, MNC, or a placebo. Patients underwent gated single photon emission computed tomography assessments at 6 and 18 months post-intramyocardial transplantation. We tested the normally distributed efficacy outcomes with a mixed analysis of variance model that used the entire data set of baseline and between-group comparisons as well as within subject (time) and group×time interaction terms.Results:There were no related serious adverse events reported. The intramyocardial transplantation of both cell types increased left ventricular ejection fraction by 9% [95% confidence intervals (CI): 2.14% to 15.78%, P=0.01] and improved decreased systolic wall thickening by -3.7 (95% CI: -7.07 to -0.42, P=0.03). The CD133 group showed significantly decreased non-viable segments by 75% (P=0.001) compared to the placebo and 60% (P=0.01) compared to the MNC group. We observed this improvement at both the 6- and 18-month time points.Conclusion:Intramyocardial injections of CD133+ cells or MNCs appeared to be safe and efficient with superiority of CD133+ cells for patients with RMI. Although the sample size precluded a definitive statement about clinical outcomes, these results have provided the basis for larger studies to confirm definitive evidence about the efficacy of these cell types (Registration Number: NCT01167751).

Results of a Safety Pooled Analysis of an Adjuvanted Herpes Zoster Subunit Vaccine in More than 14,500 Participants Aged 50 Years or Older

BackgroundThe recombinant herpes zoster (HZ) subunit vaccine (HZ/su) has shown efficacy against HZ in adults ≥50 and ≥70 years of age (YOA), in two pivotal Phase III clinical trials (NCT01165177, NCT01165229). A pooled safety analysis of data from these two efficacy studies was performed, including a comparative analysis on HZ/su vs. placebo groups, to provide a comprehensive understanding of the HZ/su safety profile.MethodsTwo pivotal, randomized, placebo-controlled Phase III studies, assessed the efficacy, reactogenicity and safety of HZ/su, administered intramuscularly according to a 0, 2-month schedule. Solicited and unsolicited adverse events (AEs) were collected for 7 and 30 days after each dose, respectively; serious AEs (SAEs) for 1 year after last dose; fatal and related SAEs and potential immune-mediated diseases (pIMDs) during the entire study period. Reactogenicity was assessed in a subset of participants; safety was assessed in all vaccinated participants.Results29,305 participants ≥50 YOA (HZ/su: 14,645; placebo: 14,660) were included in the pooled analysis. HZ/su was more reactogenic than placebo. Local reactions were mostly mild to moderate in intensity and transient (median duration = 3 days); the percentages of participants reporting SAEs, fatal SAEs and pIMDs were similar in both groups, at 30 days and 1 year after last dose (Figures 1 and 2). Percentages of fatal SAEs ranged between 4.3% (95% Confidence Interval [CI]: 4.0–4.7) and 4.6% (95% CI: 4.3–5.0) and pIMDs between 1.2% (95% CI: 1.1–1.4) and 1.4% (95% CI: 1.2–1.6), in HZ/su and placebo groups, respectively. In both groups, the most frequent causes of death were neoplasms, cardiac disorders, and respiratory tract infections and infestations, and most frequent pIMDs were polymyalgia rheumatica, rheumatoid arthritis and psoriasis.ConclusionNo safety concern was identified. Together with the high efficacy against HZ (97.2% [95% CI: 93.7–99.0],1 91.3% [95% CI: 86.8–94.5]2), the safety data supports a favorable benefit/risk profile of HZ/su in participants ≥50 YOA.FundingGlaxoSmithKline Biologicals SADisclosures M.

Heart rate control is associated with reduced cardiovascular events in Asian patients with coronary artery disease treated with bisoprolol (BISO-CAD): results from a multi-national, real-world experience

Objective: To evaluate the association between decrease in resting heart rate (RHR) and occurrence of composite cardiac clinical outcomes in coronary artery disease (CAD) patients after bisoprolol treatment.Methods: This phase IV, multi-national, single-arm, open-label, non-randomized, observational trial was conducted between October 2011 and July 2015 across 42 hospitals from China, South Korea and Vietnam.Results: Analysis of 866 patients (mean age 63.85 ± 10.35; mean RHR at baseline 75.71 ± 6.87 bpm in intent-to-treat [ITT]; 75.56 ± 6.73 in efficacy analysis [EA] sets) was performed. Patients with lower mean RHR had fewer composite cardiac events and patients with RHR of 69–74 bpm reported significantly higher outcomes than patients with RHR <65 bpm (p = .0449). A significant association with occurrence of the composite cardiac outcome and hospital admission for unstable angina or revascularization was reported in the EA set (regression estimate: 0.03, 95% CI 0.00–0.07, p = .0412) and not in the ITT set for bisoprolol treated CAD patients. Composite cardiac outcomes significantly increased in patients with mean RHR ≥70 bpm compared to patients with mean RHR <70 bpm (p = .0328). Adverse events (AEs) were reported in 206 (23.8%) patients, of whom 102 (11.8%) patients had serious adverse event (SAEs). Among the patients with SAEs, 11 (1.3%) patients died. Treatment related adverse events were only 12 (1.4%). No treatment related SAE happened.Conclusion: The findings showed bisoprolol to be efficacious, in terms of lowering RHR and causing a significant decrease in the occurrence of the composite cardiac outcome, as well as safe in Asian patients with CAD.

Safety profile of injectable hydromorphone and diacetylmorphine for long-term severe opioid use disorder

AimsTo review the safety profile of injectable hydromorphone and diacetylmorphine and explore if adverse events (AEs) or serious adverse events (SAEs) were associated with dose and patterns of attendance. MethodsThis was a non-inferiority randomized double-blind controlled trial (Vancouver, Canada) testing hydromorphone (n=100) and diacetylmorphine (n=102) for the treatment of severe opioid use disorder. Medications were delivered under the supervision of trained Registered Nurses up to three times daily. AEs were described using MedDRA codes. ResultsMost common related AEs included immediate post-injection reaction or injection site pruritus reactions, somnolence and opioid overdoses. Adjusted analysis indicated that participants in the hydromorphone group were less likely to have any related AE or SAE compared to the diacetylmorphine group. Related somnolence and opioid overdose events were distributed throughout the six months treatment period. In the diacetylmorphine group, five of the eleven related SAE opioid overdoses (requiring naloxone) occurred in the first 30days since most recent treatment initiation. Analysis of somnolence and opioid overdose (AEs and SAEs) event rates by received dose suggested a non-linear relationship. However, in the diacetylmorphine group higher event rates per person days were recorded at lower doses. ConclusionsWhen injectable hydromorphone and diacetylmorphine are individually dosed and monitored, their opioid-related side effects, including potential fatal overdoses, are safely mitigated and treated by health care providers. In the midst of an opioid overdose epidemic, injectable options are timely to reach a very important minority of people who inject street opioids and are not attracted to other treatments.

Reduction of Serious Adverse Events Demanding Study Exclusion in Model Development: Extracorporeal Life Support Resuscitation of Ventricular Fibrillation Cardiac Arrest in Rats.

Extracorporeal life support is a promising concept for selected patients in refractory cardiogenic shock and for advanced life support of persistent ventricular fibrillation cardiac arrest. Animal models of ventricular fibrillation cardiac arrest could help to investigate new treatment strategies for successful resuscitation. Associated procedural pitfalls in establishing a rat model of extracorporeal life support resuscitation need to be replaced, refined, reduced, and reported.Anesthetized male Sprague-Dawley rats (350-600 g) (n = 126) underwent cardiac arrest induced with a pacing catheter placed into the right ventricle via a jugular cannula. Rats were resuscitated with extracorporeal life support, mechanical ventilation, defibrillation, and medication. Catheter and cannula explantation was performed if restoration of spontaneous circulation was achieved. All observed serious adverse events (SAEs) occurring in each of the experimental phases were analyzed.Restoration of spontaneous circulation could be achieved in 68 of 126 rats (54%); SAEs were observed in 76 (60%) experiments. Experimental procedures related SAEs were 62 (82%) and avoidable human errors were 14 (18%). The most common serious adverse events were caused by insertion or explantation of the venous bypass cannula and resulted in lethal bleeding, cannula dislocation, or air embolism.Establishing an extracorporeal life support model in rats has confronted us with technical challenges. Even advancements in small animal critical care management over the years delivered by an experienced team and technical modifications were not able to totally avoid such serious adverse events. Replacement, refinement, and reduction reports of serious adverse events demanding study exclusions to avoid animal resources are missing and are presented hereby.

P.3.f.007 - Safety of lurasidone in schizophrenia: a systematic review and meta-analysis of short-term trials utilizing active comparator

NVX-CoV2373, a Covid-19 vaccine was developed in the USA with ∼90% efficacy. The same vaccine is manufactured in India after technology transfer (called as SII-NVX-CoV2373), was evaluated in this phase 2/3 immuno-bridging study.This was an observer-blind, randomised, phase 2/3 study in 1600 adults. In phase 2, 200 participants were randomized 3:1 to SII-NVX-CoV2373 or placebo. In phase 3, 1400 participants were randomized 3:1 to SII-NVX-CoV2373 or NVX-CoV2373 (940 safety cohort and 460 immunogenicity cohort). Two doses of study products (SII-NVX-CoV2373, NVX-CoV2373 or placebo) were given 3 weeks apart. Primary objectives were to demonstrate non-inferiority of SII-NVX-CoV2373 to NVX-CoV2373 in terms of geometric mean ELISA units (GMEU) ratio of anti-S IgG antibodies 14 days after the second dose (day 36) and to determine the incidence of causally related serious adverse events (SAEs) through 180 days after the first dose. Anti-S IgG response was assessed using an Enzyme-Linked Immunosorbent Assay (ELISA) and neutralizing antibodies (nAb) were assessed by a microneutralization assay using wild type SARS CoV-2 in participants from the immunogenicity cohort at baseline, day 22, day 36 and day 180. Cell mediated immune (CMI) response was assessed in a subset of 28 participants from immunogenicity cohort by ELISpot assay at baseline, day 36 and day 180. The total follow-up was for 6 months. Trial registration: CTRI/2021/02/031554.Total 1596 participants (200 in Phase 2 and 1396 in Phase 3) received the first dose. SII-NVX-CoV2373 was found non-inferior to NVX-CoV2373 (anti-S IgG antibodies GMEU ratio 0.91; 95% CI: 0.79, 1.06). At day 36, there was more than 58-fold rise in anti-S IgG and nAb titers compared to baseline in both the groups. On day 180 visit, these antibody titers declined to levels slightly lower than those after the first dose (13–22 fold-rise above baseline). Incidence of unsolicited and solicited AEs was similar between the SII-NVX-CoV2373 and NVX-CoV2373 groups. No adverse event of special interest (AESI) was reported. No causally related SAE was reported.SII-NVX-CoV2373 induced a non-inferior immune response compared to NVX-CoV2373 and has acceptable safety profile.SIIPL, Indian Council of Medical Research, Novavax.

Transvenous neurostimulation for central sleep apnoea: a randomised controlled trial

Central sleep apnoea is a serious breathing disorder associated with poor outcomes. The remedé system (Respicardia Inc, Minnetonka, MN, USA) is an implantable device which transvenously stimulates a nerve causing diaphragmatic contraction similar to normal breathing. We evaluated the safety and effectiveness of unilateral neurostimulation in patients with central sleep apnoea. We recruited patients from 31 hospital-based centres in Germany, Poland, and the USA in this prospective, multicentre, randomised trial. Participants had to have been medically stable for at least 30 days and have received appropriate guideline recommended therapy, be aged at least 18 years, be expected to tolerate study procedures, and willing and able to comply with study requirements. Eligible patients with an apnoea-hypopnoea index (AHI) of at least 20 events per h, tested by a polysomnography, underwent device implantation and were randomly assigned (1:1) by a computer-generated method stratified by site to either stimulation (treatment) or no stimulation (control) for 6 months. The primary effectiveness endpoint in the intention-to-treat population was the comparison of the proportions of patients in the treatment versus control groups achieving a 50% or greater AHI reduction from baseline to 6 months, measured by a full-night polysomnography assessed by masked investigators in a core laboratory. The primary safety endpoint of 12-month freedom from serious adverse events related to the procedure, system, or therapy was evaluated in all patients. This trial is active, but not recruiting, and is registered with ClinicalTrials.gov (NCT01816776). Between April 17, 2013, and May 28, 2015, we randomly assigned 151 eligible patients to the treatment (n=73) or control (n=78) groups. In the analysis of the intention-to-treat population, significantly more patients in the treatment group (35 [51%] of 68) had an AHI reduction from baseline of 50% or greater at 6 months than had those in the control group (eight [11%] of 73; difference between groups 41%, 95% CI 25-54, p<0·0001). 138 (91%) of 151 patients had no serious-related adverse events at 12 months. Seven (9%) cases of related-serious adverse events occurred in the control group and six (8%) cases were reported in the treatment group. Seven patients died (unrelated to implant, system, or therapy), four deaths (two in treatment group and two in control group) during the 6-month randomisation period when neurostimulation was delivered to only the treatment group and was off in the control group, and three deaths between 6 months and 12 months of follow-up when all patients received neurostimulation. 27 (37%) of 73 patients in the treatment group reported non-serious therapy-related discomfort that was resolved with simple system reprogramming in 26 (36%) patients, but was unresolved in one (1%) patient. Transvenous neurostimulation significantly reduced the severity of central sleep apnoea, including improvements in sleep metrics, and was well tolerated. The clinically meaningful effects of the therapy are supported by the concordant improvements in oxygenation and quality of life, making transvenous neurostimulation a promising therapeutic approach for central sleep apnoea.

Hypertonic saline (HS) for acute bronchiolitis: Systematic review and meta-analysis.

BackgroundAcute bronchiolitis is the commonest cause of hospitalisation in infancy. Currently management consists of supportive care and oxygen. A Cochrane review concluded that, “nebulised 3 % saline may significantly reduce the length of hospital stay”. We conducted a systematic review of controlled trials of nebulised hypertonic saline (HS) for infants hospitalised with primary acute bronchiolitis.MethodsSearches to January 2015 involved: Cochrane Central Register of Controlled Trials; Ovid MEDLINE; Embase; Google Scholar; Web of Science; and, a variety of trials registers. We hand searched Chest, Paediatrics and Journal of Paediatrics on 14 January 2015. Reference lists of eligible trial publications were checked. Randomised or quasi-randomised trials which compared HS versus either normal saline (+/− adjunct treatment) or no treatment were included. Eligible studies involved children less than 2 years old hospitalised due to the first episode of acute bronchiolitis. Two reviewers extracted data to calculate mean differences (MD) and 95 % Confidence Intervals (CIs) for length of hospital stay (LoS—primary outcome), Clinical Severity Score (CSS) and Serious Adverse Events (SAEs). Meta-analysis was undertaken using a fixed effect model, supplemented with additional sensitivity analyses. We investigated statistical heterogeneity using I2. Risk of bias, within and between studies, was assessed using the Cochrane tool, an outcome reporting bias checklist and a funnel plot.ResultsFifteen trials were included in the systematic review (n = 1922), HS reduced mean LoS by 0.36, (95 % CI 0.50 to 0.22) days, but with considerable heterogeneity (I2 = 78 %) and sensitivity to alternative analysis methods. A reduction in CSS was observed where assessed [n = 516; MD −1.36, CI −1.52, −1.20]. One trial reported one possible intervention related SAE, no other studies described intervention related SAEs.ConclusionsThere is disparity between the overall combined effect on LoS as compared with the negative results from the largest and most precise trials. Together with high levels of heterogeneity, this means that neither individual trials nor pooled estimates provide a firm evidence-base for routine use of HS in inpatient acute bronchiolitis.Electronic supplementary materialThe online version of this article (doi:10.1186/s12890-015-0140-x) contains supplementary material, which is available to authorized users.

Safety of Russian-backbone seasonal trivalent, live-attenuated influenza vaccine in a phase II randomized placebo-controlled clinical trial among children in urban Bangladesh

IntroductionLive-attenuated influenza vaccines (LAIVs) have the potential to be affordable, effective, and logistically feasible for immunization of children in low-resource settings. Material and methodsWe conducted a phase II, randomized, double-blind, parallel group, placebo-controlled trial on the safety of the Russian-backbone, seasonal trivalent LAIV among children aged 24 through 59 months in Dhaka, Bangladesh in 2012. After vaccination, we monitored participants for six months with weekly home visits and study clinic surveillance for solicited and unsolicited adverse events, protocol-defined wheezing illness (PDWI), and serious adverse events (SAEs), including all cause hospitalizations. ResultsThree hundred children were randomized and administered LAIV (n=150) or placebo (n=150). No immediate post-vaccination reactions occurred in either group. Solicited reactions were similar between vaccine and placebo groups during the first 7 days post-vaccination and throughout the entire trial. There were no statistically significant differences in participants experiencing PDWI between LAIV and placebo groups throughout the trial (n=13 vs. n=16, p=0.697). Of 131 children with a history of medical treatment or hospitalization for asthma or wheezing at study entry, 65 received LAIV and 66 received placebo. Among this subset, there was no statistical difference in PDWI occurring throughout the trial between the LAIV or placebo groups (7.7% vs. 19.7%, p=0.074). While there were no related SAEs, LAIV recipients had six unrelated SAEs and placebo recipients had none. These SAEs included three due to traumatic injury and bone fracture, and one each due to accidental overdose of paracetamol, abdominal pain, and acute gastroenteritis. None of the participants with SAEs had laboratory-confirmed influenza, wheezing illness, or other signs of acute respiratory illness at the time of their events. ConclusionsIn this randomized, controlled trial among 300 children aged 24 through 59 months in urban Bangladesh, Russian-backbone LAIV was safe and well tolerated. Further evaluation of LAIV safety and efficacy in a larger cohort is warranted.

Surgery in Von Willebrand Disease (VWD) Is Facilitated By a Novel 1:1 Plasma Derived Human Factor VWF/VIII Concentrate

▪This novel plasma derived, double viral attenuated VWF/FVIII concentrate with a ratio of 1:1 between both coagulant proteins (Wilate) was utilized in a pivotal clinical study conducted to further investigate its clinical efficacy and safety in VWD patients requiring surgery.This was a prospective, open-label, uncontrolled, multi-center, phase III clinical study. The primary objective was to evaluate the overall hemostatic efficacy of Wilate in preventing excessive intra- and post-operative bleeding in pediatric and adult patients with VWD. Forty–one patients, 20 major and 10 with Type 3 VWD, were planned to be enrolled to document 41 surgical procedures. During the planned interim analysis after 30 procedures, a pre-specified success rate for study termination was reached and the study was stopped early as determined by an independent data and safety monitoring board (IDMC). In vivo recovery (IVR) was investigated in all patients at the beginning of the study for pre- and post-surgical dosing. Hemostaticefficacy was assessed for each case intra- and post-operatively by the surgeons and hematologists independently, utilizing objective 4-point ordinal efficacy scales. This assessment was additionally adjudicated by the IDMC. Safety and immunogenicity were monitored throughout the study.Twenty-eight individual patients, who underwent 30 surgeries, were enrolled from 14 sites in 8 countries in Europe, Asia, and the USA. Of the 30 procedures (2 patients had more than 1 procedure), 7 had VWD Type 1 unresponsive to DDAVP (23.3%); 2 had VWD Type 2 (6.7%, one with Type 2A and one with Type 2B), and 21 had severe VWD Type 3 (70.0%). Age at baseline ranged from 12 to 74 years (median 36 years), with 3 adolescents (younger than 18 years of age) included in the study. Most surgeries were either orthopedic (10 surgeries) or dental (7 surgeries). Five surgeries were obstetric/gynecological; 4 were gastrointestinal; 3 of the ear, nose or throat; and one was ophthalmologic. In total 21 major surgeries and 9 minor surgeries were performed. Of the 21 severe VWD Type 3 patients, 17 underwent major surgery and 4 underwent minor surgery. The mean loading dose of VWF/FVIII concentrate (Wilate) per infusion (measured in VWF:RCo units) was 55.5 IU/kg for major surgeries and 37.5 IU/kg for minor surgeries. The mean maintenance dose was 30 IU/kg for major and 20.6 IU/kg for minor surgeries. Mean FVIII:C and VWF:RCo peak plasma activity levels of each patient during the maintenance infusions (infusion 1 post surgery to infusion 7), ranged from 119 IU/dL – 138 IU/dL and 66 IU/dL - 92 IU/dL, respectively, and were stable over time with no accumulation of FVIII:C (Figure 1). In the 30 procedures patients received a mean total dose (VWF:RCo) of Wilate of 434.2 ± 271.2 IU/kg (29,086 ± 17,932 IU).The overall treatment with Wilate was successful in 29 out of 30 surgeries (rate 0.967; 98.75 CI: 0.784, 1.000). Nine of 9 minor surgeries (success rate 1.000; 98.75% CI: 0.569, 1.000), and 20 of 21 major surgeries (success rate 0.952; 98.75% CI: 0.704, 1.000), were successful, as were all 21 surgeries in patients with Type 3 VWD (success rate 1.000; 98.75% CI: 0.785, 1.000).None of the patients experienced excessive intra- or post-operatively bleeding that was uncontrolled or required an alternate VWF/FVIII concentrate. No incidences of thrombotic events were reported despite 1/3 of the surgeries being orthopedic and high risk for such in non-coagulopathic populations.No FVIII or VWF neutralizing inhibitors or study drug related serious adverse events (SAEs) were observed. [Display omitted] Numbers above the graph indicate the number of observations at each dosing pointConclusion: Results of this study showed that more than 96% of the study’s surgeries treated prophylactically with Wilate were rated as having excellent or good hemostatic efficacy, as adjudicated by the IDMC. The study was terminated early because of clear and robust demonstration of efficacy, as pre-specified in the protocol. There was no accumulation of FVIII:C activity after repeat dosing. No cases of VWF or FVIII:C inhibitors, thrombotic events, or related SAEs were observed. DisclosuresSrivastava:Octapharma: Consultancy, Other. Off Label Use: Wilate is a Human VWF/FVIII product licensed in the US for treatment of acute bleeding in VWD patients but not licensed for prophylactic treatment in surgical procedures.

Safety profile of HIV-1 attachment inhibitor prodrug BMS-663068 in antiretroviral-experienced subjects: week 24 analysis.

IntroductionBMS-663068 is a prodrug of BMS-626529, an attachment inhibitor that binds directly to HIV-1 gp120, preventing initial viral attachment and entry into the host CD4+ T-cell. AI438011 is an ongoing, Phase IIb, randomized, active-controlled trial investigating the safety, efficacy and dose–response of BMS-663068 vs. atazanavir/ritonavir (ATV/r) in treatment-experienced (TE), HIV-1-positive subjects. At Week 24, response rates across the BMS-663068 arms were consistent with ATV/r.Materials and MethodsAntiretroviral TE subjects (exposure to ≥1 antiretroviral for ≥1 week) with susceptibility to all study drugs (including BMS-626529 IC50 100 nM) were randomized equally to four BMS-663068 arms (400 or 800 mg, BID; 600 or 1200 mg, QD) and a control arm (ATV/r 300/100 mg QD), with tenofovir disoproxil fumarate (TDF) + raltegravir (RAL). The complete safety profile through Week 24 is reported.ResultsIn total, 251 subjects were treated (BMS-663068, 200; ATV/r, 51). No BMS-663068-related adverse events (AEs) led to discontinuation. Grade 2–4 drug-related AEs occurred in 17/200 (8.5%) subjects across the BMS-633068 arms; however, these events were mostly single instances and no dose-relationship was seen. Similarly, no noticeable trend for Grade 3–4 laboratory abnormalities was seen and Grade 3–4 hematologic changes and liver chemistry elevations were uncommon (neutropenia, 2.5%; AST/ALT elevations, 1% (n=196)). In the ATV/r arm, Grade 2–4 drug-related AEs occurred in 14/51 (27.5%) subjects and were mostly secondary to gastrointestinal and/or hepatobiliary disorders. Serious adverse events (SAEs) occurred in 13/200 (6.5%) and 5/51 (9.8%) subjects receiving BMS-663068 and ATV/r, respectively; most were secondary to infections and none were related to study drugs. The most common AE reported for BMS-663068 was headache (28/200, 14%), occurring in 5/51 (10%) subjects in the ATV/r arm; in the BMS-663068 arms, this was not dose-related. There were no deaths.ConclusionsBMS-663068 was generally well tolerated across all arms, with no related SAEs or AEs leading to discontinuation and no dose-related safety signals. There were no trends for Grade 2–4 AEs or clinical laboratory abnormalities. These results support continued development of BMS-663068.NotePreviously submitted at IDWeek, Philadelphia, PA, 8 October 2014.

Sorafenib Therapy for BCLC Stage B/C Hepatocellular Carcinoma; Clinical Outcome and Safety in Aged Patients: A Multicenter Study in Japan.

Background and aims: We aimed to compare clinical outcomes and safety after sorafenib therapy between patients with Barcelona Clinic Liver Cancer (BCLC) stage B or C hepatocellular carcinoma (HCC) aged ≥75 years (aged group, n=179) and those with BCLC stage B or C HCC aged <75 years (control group, n=279).Patients and methods: We compared overall survival (OS), progression free survival (PFS), best treatment response and sorafenib related serious adverse events (SAEs) of grade 3 or more in the two groups. Furthermore, for reducing the selection bias, we compared clinical outcome of these two groups using propensity score matching analysis.Results: The median OS and PFS intervals were 9.7 and 3.8 months in the aged group and 8.2 and 3.3 months in the control group (P=0.641 for OS and P=0.068 for PFS). Disease control rates were 49.2% (88/179) in the aged group and 49.1% (137/279) in the control group (P>0.999). Objective response rates were 15.1% (27/179) in the aged group and 14.3% (40/279) in the control group (P=0.892). Treatment related SAEs of grade 3 or more were observed in 51 patients (28.5%) in the aged group and in 69 patients (24.7%) in the control group (P=0.385). In the propensity score matched cohort (132 pairs), no significant difference in the two groups was observed in terms of OS (P=0.898) and PFS (P=0.407).Conclusion: In BCLC stage B or C HCC patients treated with sorafenib, life expectancy, disease progression, treatment efficacy and SAEs are unaffected by age over 75 years.

Registry Of Patients Treated With Protein C Concentrate (Human) In The United States and Europe: Interim Results

BackgroundProtein C (PC) is a naturally occurring, vitamin-K dependent anticoagulant produced by the liver. Deficiency of PC, which can be congenital or acquired, results in a hypercoagulable state. Patients with severe PC deficiency may manifest severe, often life-threatening, disseminated intravascular coagulation (DIC), purpura fulminans (PF), and/or thromboembolism. Highly purified protein C concentrate prepared from human donor plasma (Ceprotin; Baxter Healthcare Corporation, Westlake Village, CA) is an approved therapy for prevention and treatment of venous thrombosis and PF in patients with severe congenital PC deficiency (SCPCD) in the United States. It is indicated in patients with SCPCD for PF and coumarin-induced skin necrosis, and short-term prophylaxis in the European Union and other countries. Use of protein C concentrate (human) has been reported in patients with acquired PC deficiency. The Ceprotin Treatment Registry is a prospective, international, multi-center, open-label, non-interventional, observational study designed to examine the long-term safety and effectiveness of protein C concentrate (human) in the clinical setting. This is the first large, real-world assessment of the treatment of a rare disease with protein C concentrate (human). Here we report data from the first interim analysis in June 2013 covering a 3-year enrollment period. MethodsPatients of any age who received, or were initiating/receiving protein C concentrate are included. The study duration is 5 years (3-year enrollment period plus 2 years of follow-up). All study visits/assessments are in accordance with standard of care, with protein C concentrate dose, dose frequency, duration and route of administration determined by the investigator. The study objectives are to determine the most common medical diagnoses associated with protein C concentrate treatment, protein C concentrate treatment regimens, and safety information based on all serious adverse events (SAEs) and rate of treatment-related AE. Other objectives include: an examination of the relationship between protein C concentrate treatment and outcomes in all registry participants, as well as various subgroups. Descriptive statistical analyses are used. ResultsAt the time of data extraction, 34 patients were enrolled from 26 centers; 10 centers in the United States and 16 centers in Europe. Half of the patients were males. The primary diagnosis of PC deficiency was congenital in 25 patients (73.5%) and acquired in 9 patients (26.5%). The median age at diagnosis was 0.03 years (range 0–19.9). Mean plasma PC activity level was 9% (range 1–40.0). The most common (in ≥3 patients) thrombotic disease-associated conditions were PF (50.0%); blindness (44.1%); thromboembolic disease (41.2%), which included deep vein thrombosis, arterial thrombosis and DIC; stroke (32.4%), and renal dysfunction (8.8%). Of the 23 patients being treated with protein C concentrate, 15 were administered protein C concentrate intravenously, and 8 patients received protein C concentrate subcutaneously. The body weights of patients receiving subcutaneous treatment ranged from 10.0 kg to 57.9 kg. A total of 15 patients received an anticoagulant treatment in addition to protein C concentrate. Eight patients reported 23 SAEs, all of which were considered not related to treatment. Eighteen (52.9%) patients reported 72 AEs; only 1 of them, an episode of upper respiratory infection, was considered possibly treatment-related. In 18 patients in whom PC activity recovery was determined after protein C concentrate treatment, there were no patients documented with poor recovery. Protein C concentrate was used during 18 surgeries/invasive procedures and considered effective in all interventions for which data were available. ConclusionsData from the first interim analysis of the Ceprotin Treatment Registry demonstrate that patients with both congenital and acquired severe PC deficiency who are treated with protein C concentrate (human) have a low incidence of treatment related SAEs and AEs, and treatment with protein C concentrate appears to be effective when used during surgery/invasive procedures. Further patient follow up will shed light onto clinical treatment outcomes.

How many published cases of serious adverse events after yellow fever vaccination meet Brighton Collaboration diagnostic criteria?

ObjectivesTo perform a systematic review of all serious adverse events (SAEs) after yellow fever vaccination and to assess them according to Brighton Collaboration criteria. MethodsNine electronic databases were searched with the terms “yellow fever vaccine” and “adverse events” to 10 July 2013 (no language/date limits). Two reviewers independently assessed studies, entered data, and assessed cases with Brighton Collaboration criteria. ResultsOne hundred and thirty-one cases met Brighton Collaboration criteria: 32 anaphylaxis, 41 neurologic (one death), 56 viscerotropic (24 deaths), and 2 both neurologic and viscerotropic criteria. All SAEs occurred following first yellow fever (YF) vaccination. Two additional cases which met Brighton Collaboration criteria were proven due to wild virus.An additional 345 cases were presented with insufficient detail to meet Brighton Collaboration criteria: 173 neurological, 68 viscerotropic (24 deaths), 67 anaphylaxis, and 34 cases from a UK database and 3 from a Swiss database described as “serious adverse events” but not further classified into neurologic or viscerotropic. A further 253 cases were excluded as presenting insufficient data to be regarded as yellow fever vaccine (YFV) related SAEs. ConclusionsOne hundred and thirty-one cases met Brighton Collaboration criteria for serious adverse events after yellow fever vaccination. Another 345 cases did not meet Brighton criteria and 253 were excluded as presenting insufficient data to be regarded as serious adverse events after YFV. There are likely to be cases in areas that are remote or with insufficient diagnostic resources that are neither correctly assessed nor not published.

Bendamustine (Treanda®), Etoposide and Dexamethasone (BED) Followed by GCSF Effectively Mobilizes Autologous Peripheral Blood Hematopoietic Stem Cells

AbstractAbstract ▪4126▪This icon denotes a clinically relevant abstract Background:High dose chemotherapy followed by autologous stem cell transplantation (ASCT) is a standard of care for patients with advanced or treatment refractory multiple myeloma (MM) and non-Hodgkin lymphoma (NHL). Stem cell proliferation and mobilization can be enhanced though the addition of myelosuppressive chemotherapy to GCSF administration. Chemotherapeutic agents without cross resistance to prior therapies may support peripheral blood stem cell (PBSC) collection and improve patient outcomes by exacting a more potent direct anti-tumor effect prior to ASCT. Bendamustine (Treanda®) is a synthetic chemotherapeutic agent that shares structural similarities to both purine analog and alkylating agents without significant cross resistance to other compounds in either drug class. Bendamustine appears to have low stem cell toxicity in vitro, is well tolerated, and has activity in MM and NHL. We hypothesized that bendamustine’s activity in patients with disease resistant to first line therapies makes it a logical candidate for chemotherapy based PBSC mobilization. Methods:Patients were eligible if they had relapsed or refractory MM, B-cell NHL or T-cell NHL and were candidates for ASCT. Other criteria included: age >18 years, ANC >1,500/mm3, platelets >100,000/mm3, adequate renal and hepatic function, <3 prior myelotoxic regimens, <6 cycles of lenalidomide, no prior failed mobilization attempt, and no prior pelvic/spinal irradiation. Patients received 1 cycle of BED therapy [bendamustine (120 mg/m2 IV d 1, 2 - provided along with financial support for this study by Teva Pharmaceuticals), etoposide (200 mg/m2 IV d 1– 3), dexamethasone (40 mg PO d 1– 4), delivered as an outpatient, followed by filgrastim (10 mcg/kg/day; starting on d 5 through end of collection)]. Apheresis was initiated when peripheral blood CD34 cell counts were >5/μL. The primary endpoint was successful mobilization, defined as collection of >2.0 × 106CD34 cells/kg. Adverse events (AEs) were graded using the CTCAE v4.0. Results:Twenty patients (16 MM, 3 B-cell NHL, 1 NK/T-cell NHL) were treated. The median age was 59 years (range 43–70), and the median number of prior therapies was 1 (range 1–3) for MM and 2 (range 2–3) for NHL patients. All patients (20/20) were successfully mobilized. The median number of CD34+ cells collected was 19.11 × 106/kg (Mean 22.49; range 4.35 to 55.51 × 106). All MM patients collected >10 × 106 CD34+cells/kg. The median time from BED mobilization therapy to the first day of CD34 stem cell collection was 12 days (mean 12.05; range 10 to 20 days). The median number of days of apheresis was 1 (mean 1.45; range 1 to 4). A predictable pattern of leucocyte nadir and recovery was demonstrated (88% of patients started apheresis between days 10–12). One patient (5%) was given plerixafor and for 2 patients (10%) the dose of GCSF was increased to 16 mcg/kg twice daily. Among the 20 patients mobilized and collected, 12 have thus far undergone ASCT and 100% (12/12) have achieved an unsupported neutrophil count >500/μL at an average of 14.3 days after PBSC infusion and a platelet count >20K/μL at an average of 10 days. Serious AEs (SAEs) were observed in 5 patients and 1 patient died due to disease progression. No unexpected grade 3 or greater treatment related SAEs were seen. Disease response assessments are ongoing. The original protocol design involved 3 agents (bendamustine, dexamethasone and GCSF [BDG]). After the first 3 patients enrolled, the mobilization regimen was modified to include etoposide because BDG did not yield a predictable pattern of leucocyte nadir and recovery, thus complicating timing for apheresis (median time to collection 22 days). The first 3 patients were censored from the analysis, however all 3 patients were successfully mobilized and collected. Conclusions:The initial experience with PBSC mobilization after BED in this phase II study suggests the regimen is safe and effective, while the use of BDG does not yield predictable CD34 kinetics. Time to neutrophil and platelet engraftment after ASCT appears unimpaired when compared with other chemotherapy based mobilization regimens. Large numbers of stem cells were rapidly mobilized and resulted in short durations of apheresis. No patient with MM collected <10 × 106 CD34+ cells/kg (sufficient for 2 ASCTs). The regimen was very well tolerated and these findings suggest that the role of bendamustine in PBSC mobilization should be further explored. Disclosures:Green:Teva Pharmaceuticals: Research Funding.

Randomized phase II study of the x-linked inhibitor of apoptosis (XIAP) antisense AEG35156 in combination with sorafenib in patients with advanced hepatocellular carcinoma (HCC).

4105 Background: XIAP inhibits caspases which are proteases responsible for apoptotic cell death. It is highly expressed in HCC. AEG35156 is a second generation antisense oligonucleotide targeting XIAP mRNA, thus lowers the apoptotic threshold of cancer cells. It also accumulates in the liver. This study is designed to assess the added benefit of combining AEG35156 with sorafenib. Methods: Patients with histologically or clinically diagnosed (AASLD criteria) HCC who had failed or were unsuitable for resection or ablative therapies were randomized (2:1) to receive either weekly injection of AEG35156 300mg in combination with sorefanib 400mg BID or sorefanib alone. The primary end point was progression-free survival (PFS). Other endpoints were overall survival (OS), response rates and safety. Results: 51 patients were recruited. 48 patents were evaluable. There were 31 patients in the combination arm and 17 in the control arm. The median age was 60. 88% of patients were male. 81% of patients were hepatitis B carrier. 90% of patients belong to Child-Pugh class A. The median follow-up was 16.2 months. The PFS for the combination arm was 4.0 months (95% CI: 1.2-4.1) and 2.6 months for control arm. The OS for the combination arm was 6.5 months (95% CI: 3.9-11.5) and 5.4 months for the control arm. There were 3 partial responders (Choi’s criteria) in the combination arm (10%, 95% CI: 3-27%) and none (0%) in the control arm. Patients who had the study treatment interrupted (PFS 4.0, 95% CI: 2.4-5.4) or had dose modification (PFS 4.45, 95% CI: 1.0-6.5) according to protocol did significantly better than those who had no dose reduction (PFS 1.2, 95% CI: 1.2-4.0) and those in the control arm (PFS 2.6, 95% CI: 1.2-5.4). This also applies to OS. Regarding toxicities, there were one AEG35156 related serious adverse event (SAE) of hypersensitivity and two sorafenib related gastrointestinal SAE. Conclusions: AEG35156 in combination with Sorafenib was well tolerated in patients with advanced HCC. Dose reduced AEG35156 in combination with sorafenib have shown more activity than sorafenib alone and warrants further investigation.
