Safety of sarilumab in a Japanese population with rheumatoid arthritis by age group: Data from an interim analysis of a post-marketing surveillance study.

Using data from a post-marketing surveillance, this interim subgroup analysis investigated the safety of sarilumab in younger (<65 years) and older patients (≥65 and ≥75 years) with rheumatoid arthritis. During this interim analysis, patients who were treated with sarilumab in Japan were enrolled between June 2018-2021. Data collected by 12 January 2022 were analysed, with adverse drug events monitored over 52 weeks. Of 972 patients with available data, proportion of patients aged <65 years, ≥65 years and ≥75 years were 40.8%, 59.2% and 27.8%, respectively. Most patients (95.5%) received the standard 200 mg dose of sarilumab as the initial dose. Adverse drug reactions were reported in 24.6% of patients, with serious events accounting for 6.4% of cases. No malignancy and low incidences of adverse drug reactions of special interest were reported across all age groups (<65 years, 7.8%; ≥65 years, 8.2%; ≥75 years, 8.5%). When stratified by absolute neutrophil count above and below the lower limit of normal, there were no numerical differences in incidences of serious and non-serious infections between age groups. Regardless of age, sarilumab therapy was well tolerated by patients with rheumatoid arthritis, with no new safety signals reported in this study.

#636 A phase 4, open label, multicenter prospective study of the safety and efficacy of agalsidase beta in Chinese patients with Fabry disease

Abstract Background and Aims Fabry disease (FD) is a rare inherited lysosomal storage disease caused by pathogenic GLA gene variants which result in a deficiency of the enzymatic activity of α-galactosidase A. Enzyme replacement therapy (ERT) is the mainstay of FD-specific treatment, but there are currently no reported clinical trials of ERT for FD in the Chinese population. This is the first phase 4 study to evaluate the safety and efficacy of ERT for FD in China since the approval of agalsidase beta in China in 2019. Method A 54-week, phase 4, open label, single arm, prospective, post-marketing surveillance (PMS) study of agalsidase beta (NCT05054387) was performed at 6 sites in China. Twenty-two Chinese ERT-naïve FD participants (≥8 years) with estimated glomerular filtration rate (eGFR) ≥30 mL/min/1.73 m2 were enrolled and received infusions of agalsidase beta (Fabrazyme®, Sanofi) at a dose of 1.0 mg/kg every 2 weeks for up to 48 weeks. The primary endpoint was safety and tolerability of agalsidase beta. The endpoints of clinical efficacy included the changes of plasma globotriaosylceramide (GL-3), globotriaosylsphingosine (Lyso-GL-3), FD symptoms (including angiokeratoma, hypohidrosis, anhidrosis, abdominal pain, headache, tinnitus, heat tolerance, and activity tolerance), and eGFR from baseline to week 48. A post-hoc subgroup analysis was conducted to explore the differences in ERT efficacy between two subgroups of different ages (&amp;lt;30 years and ≥30 years). Results All 22 patients completed the study intervention. There were 18 males (81.8%) and the mean age of ERT initiation was 29.0 ± 13.5 years. Treatment-related adverse events (AEs) and infusion-associated reactions (IARs) were reported in 8 participants (36.4%), which was less than ∼60% as previously reported for IARs. Most AEs were mild or moderate and no AE caused permanent treatment discontinuation or death. The mean plasma GL-3 and Lyso-GL-3 levels decreased remarkably at week 6 and remained stable throughout the trial, with the mean percentage reduction from baseline to week 6 through week 48 ranged from −34.6% ± 27.4% to ­41.9% ± 14.9% and −58.8% ± 20.2% to ­64.9% ± 12.7%, respectively (Fig. 1a and b). The reduction was more remarkable for the classic male patients (n = 18; GL-3: 7.99 ± 2.19 ug/mL at baseline and 4.31 ± 1.71 ug/mL at week 48, −46.0% ± 18.4%; Lyso-GL-3: 83.11 ± 25.69 ng/mL at baseline and 25.89 ± 13.43 ng/mL at week 48, −67.8% ± 17.6%). Thirteen (59.1%) participants experienced improved FD symptoms at week 48, with no cases of worsening symptoms. The mean eGFR was 115.6 ± 37.3 mL/min/1.73 m2 at baseline and 118.4 ± 42.9 mL/min/1.73 m2 at week 48, with a change of 0.0 ± 12.4 mL/min/1.73 m2 from baseline to week 48 (Fig. 1c). In the subgroup analysis, participants were divided into the younger group with age &amp;lt;30 years (n = 11) and the older group with age ≥30 years (n = 11) according to their age of ERT initiation. At week 48, the reduction of mean plasma GL-3 (−47.1% ± 23.6% vs −22.0% ± 26.0%) and Lyso-GL-3 levels (−72.4 ± 17.3% vs −48.2% ± 19.8%), the stabilization of renal function (the mean change of eGFR from baseline to week 48: 5.2 ± 7.9 mL/min/1.73 m2 vs −5.2 ± 14.1 mL/min/1.73 m2) and the percentage of symptom improvement (81.8% vs. 36.4%) were generally more remarkable in the younger group than in the older group (Table 1). Conclusion This first phase 4 study of ERT for Fabry disease in China demonstrates that agalsidase beta is safe and well tolerated with a relatively low IAR rate, and effective in reducing plasma GL-3 and Lyso-GL-3, improving symptoms, and stabilizing renal function in Chinese patients with FD. Furthermore, the present study implies that patients who initiate ERT at a younger age benefit more from the therapy. Funding: Commercial support - Sanofi Pharmaceuticals.

Safety and effectiveness of apremilast in Japanese patients with psoriatic disease: Results of a post-marketing surveillance study.

The safety and efficacy of apremilast in psoriatic disease has been demonstrated in clinical trials, including in Japanese patients. This post-marketing surveillance study was conducted after approval of apremalast in Japan in 2016 to evaluate the safety and effectiveness of the drug in Japanese patients with plaque psoriasis (PsO) and psoriatic arthritis (PsA) in routine clinical practice. Patients (enrolled between September 1, 2017, and August 31, 2019), were observed for 12 months after apremilast treatment initiation or until discontinuation or withdrawal. Safety was assessed by evaluating adverse reactions (ARs) and serious ARs. Effectiveness measures in PsO included the proportion of patients who achieved global improvement and Physician's Global Assessment (PGA) scores of 0/1 and the change from baseline in the Dermatology Life Quality Index (DLQI) after 6 and 12 months treatment. The safety analysis set included 1063 patients (PsO, n = 992; PsA, n = 127). ARs and serious ARs were reported in 29.4% and 0.7% of patients, respectively; most occurred <1 month after apremilast initiation. There were no reports of fatal ARs, serious infections, hypersensitivity, or vasculitis. No new safety signals were identified. Among the key survey items, gastrointestinal disorders were the most common ARs (21.3%). In patients with PsO, after 6 and 12 months of treatment, effectiveness rates of achieving highly effective or effective global improvement of were 90.9% and 93.8%; PGA 0/1 was achieved by 42.7% and 58.1% of patients; mean decrease from baseline in total DLQI score was 4.2 (p < 0.0001) and 5.7 (p < 0.0001), respectively. Effectiveness was evaluated in a small number of patients with PsA for some measures; after 6 and 12 months of treatment, improvements were observed in global improvement effectiveness rates, Disease Activity Score in 28 Joints score, Visual Analog Scale score, and DLQI score. We conclude that orally administered apremilast was well tolerated and effective in Japanese patients with PsO and/or PsA enrolled in this post-marketing surveillance study.

Relationship between Anaplastic Lymphoma Kinase Inhibitors and Epileptic Seizure Disorder: A Post-Marketing Surveillance Study

Introduction: Anaplastic lymphoma kinase (ALK) has been to be involved in the uptake and regulation of dopamine 2 receptor (D2R), a G protein-coupled receptor expressed in various brain regions. Therefore, it is crucial to understand the relationship between ALK inhibitors and seizures is an important issue. This study investigated the relationship between ALK inhibitors and seizures. Methods: This study investigated the relationship between ALK inhibitors and seizures through a disproportionality analysis using the US Food and Drug Administration (FDA) Adverse Event Reporting System (FAERS). The target drugs were the ALK inhibitors crizotinib, ceritinib, alectinib, brigatinib, and lorlatinib. The seizures covered were defined high-level group term (HLGT): “Seizures (incl. subtype)” including high-level term (HLT): “seizures and seizure disorders NEC.” This study used the information component (IC), a signal score, as a Bayesian statistical method for disproportionality analysis. The signal detection criteria used in this study were the same as those reported previously: a lower limit of 95% credible interval (CrI) for IC >0. Results: The signal scores of '“seizures and seizure disorders not elsewhere classified (NEC)” “for each ALK inhibitor were crizotinib (IC: −0.00052, 95% CrI: −0.38–0.27), ceritinib (IC: 1.18, 95% CrI: 0.68–1.54), alectinib (IC: 0.68, 95% CrI: 0.19–1.02), brigatinib (IC: 1.04, 95% CrI: 0.32–1.54), and lorlatinib (IC: 0.82, 95% CrI: 0.11–1.32). On the other hand, “generalized tonic-clonic seizures,” “partial simple seizures NEC,” “absence seizures,” and “partial complex seizures” had no or few reported cases, and no signal was detected. Conclusion: To our knowledge, this is the first report to evaluate the relationship between ALK inhibitors and seizures using post-marketing surveillance data. These results suggest that ceritinib, alectinib, brigatinib, and lorlatinib, which are highly brain-migrating drugs, are associated with seizures.

Safety and Effectiveness of Ustekinumab for Crohn's Disease With Perianal Manifestations: Ad hoc Analysis Data From 1-Year Post-Marketing Surveillance Study in Japan.

Crohn's disease (CD) is an immune-mediated inflammatory disorder of the gastrointestinal tract with perianal disease being one of the challenging possible manifestations. Here, we report, an ad hoc analysis of the safety and effectiveness of 1-year use of ustekinumab (UST) for CD in patients with perianal manifestations using post-marketing surveillance (PMS) data in Japan. Among 341 patients enrolled in the PMS, 229 and 224 patients who had baseline Crohn's Disease Activity Index (CDAI) data used for evaluating perianal manifestations were included in the safety and efficacy analysis sets, respectively. Incidence of adverse drug reactions, clinical remission, the mean or its change in CDAI scores, and CDAI items were evaluated through week 52 in the presence or absence of perianal manifestations at baseline. The prevalence of perianal manifestations was also described. Comparing patients with and without baseline perianal manifestations at week 52, there was no difference in ADR incidence (9.1% [n = 66] vs. 15.3% [n = 163]), no difference in clinical remission (68.3% vs. 59.9%; P = 0.269), and decreased mean change of CDAI score (-82.9 [n = 60] vs. -68.8 [n = 137]). The proportion of patients with perianal manifestations decreased after UST treatment in both biologics-naïve patients (23.5% [n = 4/17]) and patients who had received biologics (35.0% [n = 14/40]) at week 52. In Japanese clinical practice, UST is safe and effective in CD patients with and without perianal manifestations. The therapy might be also beneficial in those with manifestations regardless of prior use of other biologics.

Real-world outcomes of ponatinib treatment in 724 patients with CML and Ph+ ALL: a post-marketing surveillance study with a special interest in arterial occlusive events in Japan.

In September 2016, ponatinib was approved in Japan for the treatment of patients with chronic myeloid leukemia with resistance/intolerance to prior tyrosine kinase inhibitors and patients with relapsed or refractory Philadelphia chromosome-positive acute lymphoblastic leukemia. We conducted a post-marketing all-case surveillance to study the safety and efficacy of ponatinib in clinical practice, focusing on arterial occlusive events. Data from 724 patients were collected for 2years from the initiation of ponatinib. The arterial occlusive events were reported in 6.49% (47/724) with an exposure-adjusted incidence rate of 6.8/100 person-years. The risks associated with arterial occlusive events were age and comorbidities including hypertension and diabetes. At 104weeks, the cumulative major molecular response rate in patients with chronic-phase chronic myeloid leukemia was 67.2% and the complete cytogenetic response in patients with Philadelphia chromosome-positive acute lymphoblastic leukemia was 80.0%. Furthermore, the estimated 1-year overall survival rate was 98.5% for chronic-phase chronic myeloid leukemia and 68.6% for Philadelphia chromosome-positive acute lymphoblastic leukemia. This surveillance demonstrated that ponatinib has a favorable safety and efficacy profile in Japanese patients and also showed the necessity of closely monitoring arterial occlusive events in older adults and patients with predisposing factors for atherosclerosis.

Real-World Patent Foramen Ovale (PFO) Closure in Japan - 30-Day Clinical Outcomes From the AmplatzerTM PFO Occluder Japan Post-Marketing Surveillance Study.

The AmplatzerTM PFO Occluder was approved for marketing in Japan in May 2019, and the Amplatzer PFO Occluder Japan Post-marketing Surveillance (PFO Japan PMS) study was initiated in December 2019. This analysis presents 30-day clinical outcomes for PFO Japan PMS study patients. PFO Japan PMS is a prospective single-arm non-randomized multicenter clinical study. Eligible patients were indicated for patent foramen ovale (PFO) closure and underwent an implant attempt with the AmplatzerTM PFO Occluder. Technical success was defined as successful delivery and release of the occluder; procedural success was defined as technical success with no serious adverse events (SAEs) within 1 day of the procedure. The primary safety endpoint includes predefined device- and/or procedure-related SAEs through 30 days after the procedure. From December 2019 to July 2021, 500 patients were enrolled across 53 Japanese sites. The mean (±SD) patient age was 52.7±15.4 years, and 29.8% of patients were aged >60 years. Technical and procedural success rates were both high (99.8% and 98.8%, respectively). Further, there was only one primary safety endpoint event (0.2%): an episode of asymptomatic paroxysmal atrial fibrillation that occurred 26 days after the procedure. In this real-world Japanese study with almost one-third of patients aged >60 years, PFO closure with the AmplatzerTM PFO Occluder was performed successfully and safely, with a low incidence of procedure-related atrial arrhythmias.

A Post-Marketing Surveillance Study of Nusinersen for Spinal Muscular Atrophy in Routine Medical Practice in China: Interim Results.

Spinal muscular atrophy (SMA) is a rare, autosomal recessive, neuromuscular disease that leads to progressive muscular weakness and atrophy. Nusinersen, an antisense oligonucleotide, was approved for SMA in China in February 2019. We report interim results from a post-marketing surveillance phase 4 study, PANDA (NCT04419233), that collects data on the safety, efficacy, and pharmacokinetics of nusinersen in children with SMA in routine clinical practice in China. Participants enrolled in PANDA will be observed for 2years following nusinersen treatment initiation. The primary endpoint is the incidence of adverse events (AEs)/serious AEs (SAEs) during the treatment period. Efficacy assessments include World Health Organization (WHO) Motor Milestones assessment, the Hammersmith Infant Neurological Examination (HINE), and ventilation support. Plasma and cerebrospinal fluid (CSF) concentrations of nusinersen are measured at each dose visit. Fifty participants were enrolled as of the January 4, 2023, data cutoff: 10 with infantile-onset (≤ 6months) and 40 with later-onset (> 6months) SMA. All 50 participants have received at least one dose of nusinersen; 6 have completed the study. AEs were experienced by 45 (90%) participants and were mostly mild/moderate; no AEs led to nusinersen discontinuation or study withdrawal. Eleven participants experienced SAEs, most commonly pneumonia (n = 9); none were considered related to study treatment. Stability or gain of WHO motor milestone was observed and mean HINE-2 scores improved in both subgroups throughout the study. No serious respiratory events occurred,and no permanent ventilation support was initiated during the study. Pre-dose nusinersen CSF concentrations increased steadily through the loading-dose period, with no accumulation in plasma after multiple doses. Nusinersen was generally well tolerated with an acceptable overall safety profile, consistent with the known safety of nusinersen. Efficacy, safety, and nusinersen exposure are consistent with prior observations. These results support continuing PANDA and evaluation of nusinersen in Chinese participants with SMA. ClinicalTrials.gov identifier, NCT04419233.

A Single Centric, Open-Label, Non-Randomized Post- Marketing Surveillance Study to Measure the Efficacy and Safety of Petsaffa Tablets in Subjects Suffering From Constipation, Gas and Acidity

Constipation, gas, and acidity are common gastrointestinal issues with a significant global prevalence. Traditional medicine systems like Ayurveda have long utilized medicinal plants to address these concerns. However, clinical validation of their efficacy in patients with constipation has been lacking. Objectives: This study aimed to assess the efficacy and safety of Petsaffa tablets, an Ayurvedic formulation containing various herbal ingredients, in relieving constipation, gas, and acidity. Methods: The study, conducted as a single-centric, open-label, non-randomized post-marketing surveillance study, involved 120 subjects with constipation. Subjects were evaluated using inclusion and exclusion criteria and provided Petsaffa tablets for a 14-day intervention. Various parameters, including bowel movement frequency, constipation scores, and subjective assessments, were measured. Vital signs, laboratory safety parameters, and adverse events were also monitored during the study period. Results: Petsaffa tablets significantly improved bowel movement frequency, constipation scores, and subjective symptoms related to constipation. Stool consistency and other associated symptoms such as acidity and gas were also reduced at the end of the study. None of the participants reported any adverse events, and safety parameters remained within normal limits during the study period. Conclusion: Petsaffa tablets offer a promising, safe, and effective alternative option for individuals with common gastrointestinal issues such as constipation, acidity, and gas.

Maternal supplementation with docosahexaenoic acid does not cause constriction of fetal ductus arteriosus: randomized controlled trial.

Docosahexaenoic acid (DHA) is recommended routinely in pregnancy to promote fetal development. DHA has anti-inflammatory activity, but its effects on the fetal heart and circulation are unknown. This study aimed to investigate whether maternal DHA supplementation in the third trimester affects maternal prostaglandin levels and fetal ductus arteriosus flow dynamics. This was a double-blind randomized controlled trial with parallel groups conducted between 2018 and 2021. Pregnant women aged over 18 years with a normal fetus at 27-28 weeks' gestation showing no cardiac/extracardiac anomalies or ductal constriction were eligible for the trial. Women consuming substances with a known inhibitory effect on prostaglandin metabolism, such as non-steroidal anti-inflammatory drugs and polyphenol-rich foods, were excluded. The intervention group received oral supplementation of omega-3 with 450 mg/day of DHA for 8 weeks and the placebo group received capsules of soy lecithin for 8 weeks. Anthropometric measurements, assessment of polyphenol and omega-3 consumption, fetal morphological ultrasound examination, fetal Doppler echocardiographic examination and blood sample collection were performed at the start of the study and the latter two were repeated at follow-up. Prostaglandin E2 (PGE2) level and echocardiographic parameters were compared between the intervention and placebo groups and between baseline and follow-up. A total of 24 participants were included in each group. After 8 weeks, there were no significant differences between the intervention and placebo groups in maternal serum PGE2 level or Doppler echocardiographic parameters of ductal flow. No case of ductus arteriosus constriction was observed. The expected intragroup changes in cardiac morphology, as a result of advancing gestation, were present. Maternal DHA supplementation in the third trimester at a clinically recommended dose did not result in inhibition of PGE2 or constriction of the ductus arteriosus. These findings should be confirmed in postmarket surveillance studies with larger patient numbers in order to test the full safety profile of DHA and provide robust clinical reassurance. © 2024 International Society of Ultrasound in Obstetrics and Gynecology.

Safety and effectiveness of clofarabine in Japanese patients with relapsed/refractory acute lymphoblastic leukaemia: a post-marketing surveillance study.

Clofarabine is used to treat acute lymphoblastic leukaemia, but evidence of its safety and effectiveness in Japanese patients is limited. We evaluated the safety and effectiveness of clofarabine in patients with relapsed/refractory acute lymphoblastic leukaemia in real-world clinical practice in Japan. An observational, multicenter, post-marketing, all-case surveillance was conducted for safety. Effectiveness analyses were conducted in patients aged ≤21years and those treated with clofarabine monotherapy and combination therapy (clofarabine plus etoposide and cyclophosphamide). In the all-case survey, 260 of 264 registered patients were eligible for safety analysis. Among the 225 patients eligible for effectiveness analysis, 139 were aged ≤21years. For monotherapy and combination therapy, 20/31 and 34/88 patients were eligible, respectively. In the all-case survey, the median age was 16.0years, and 47.7% of patients were<15years old. Adverse drug reaction incidence was 83.5% and the most common were hematologic toxicities. The best overall response rates in the population aged ≤21years were complete remission, 29.7%; complete remission without platelet recovery, 7.3% and partial remission, 10.9%. The rest (52.2%) were classified as ineffective. The sum of complete remission, complete remission without platelet recovery and partial remission rates (effectiveness rate) was 47.8% (66/138 patients). The effectiveness rates in the monotherapy and combination therapy surveys were 10.0% (2/20 patients) and 58.8% (20/34 patients), respectively. These post-marketing surveys provide real-world evidence of the safety and effectiveness of clofarabine regimens, including monotherapy and combination therapy in Japanese patients with relapsed/refractory acute lymphoblastic leukaemia. The safety and effectiveness profiles were comparable with those of previous prospective studies.

A Systematic Analysis of COVID-19 Clinical Trials Registered in the Clinical Trials Registry of India.

The Clinical Trials Registry - India (CTRI) database is a registry of various trials conducted in India and this study scrutinized the studies registered for COVID-19 from the database to detect patterns in trial design, appraising the target regions of therapiesand comprehending the terrain of research endeavors. This was a cross-sectional study that analyzed the registered trials for COVID-19 between March 2020 and September 2023. A trial search was conducted on the CTRI database to include all types of studies registered for COVID-19 with keywords like "COVID" and "coronavirus" and studies conducted on conditions other than COVID-19 were excluded. The data regarding study characteristics were noted under various sections in a preformed proforma. A total of 807 trials were taken for final analysis and there were about 344 prospective and 260 retrospective interventional trials, 35 prospective and 165 retrospective observational studies, and two prospective and one retrospective post-marketing surveillance study. The majority of the studies had duration under 12 months (91%). The maximum number of studies were registered from AYUSH (Ayurveda, Yoga and Naturopathy, Unani, Siddha, and Homeopathy) and allied therapies (n = 283), with about 104 types of interventions, followed by the drug category having 119 trials registered and about 57 types of interventions. Kabasura Kudineer and yoga in the AYUSH category, molnupiravir, colchicine, and favipiravir in the drug category, and tocilizumaband convalescent plasma among biologics were some common interventions used. The majority of trials did not mention the trial phase and declared it as not applicable (54%), whereas 15% were registered as phase 2 and 13% as phase 3. About 54% of the studies were randomized and randomized parallel-group design (20%) was the most common study design. Only 6% of the trials were post-graduate thesis and the majority of the trials (n = 535) denied sharing their individual participant data. Only 0.86% and 0.61% of the trials were terminated and suspended, respectively, denoting proper design and conduct of the trials. In the CTRI database, the majority of trials were prospective interventional studies, with a predominance of AYUSH therapies and drug interventions. Common interventions included Kabasura Kudineer and yoga in AYUSH, and molnupiravir, colchicine, and favipiravir in drugs. Most studies had durations under 12 months and randomized parallel-group design was the most common study design. The intention to use and promote an indigenous system of medicine looks promising in the absence of any definite therapy. A minute number of registered suspended and terminated trials might bea positive picture of meticulously designed and executed trials even during a pandemic situation in India.

Efficacy and safety of biosimilar trastuzumab (CT-P6) in routine clinical practice in the Republic of Korea: a real-world post-marketing surveillance study

ABSTRACT Background The trastuzumab biosimilar CT-P6 is approved for human epidermal growth factor receptor 2 (HER2)–positive early breast cancer (EBC), metastatic breast cancer (MBC), and metastatic gastric cancer (MGC). The objective of this post-marketing surveillance (PMS) study was to evaluate the real-world safety and effectiveness of CT-P6 in patients with HER2-positive cancers. Research design and methods This open-label, observational, prospective, PMS study collected data via investigator surveys from 35 centers in the Republic of Korea (5 October 2018–4 October 2022). Eligible patients with HER2-positive EBC, MBC, or MGC started CT-P6 treatment during routine clinical practice, followed by 1-year observation. Evaluations included adverse events (AEs), adverse drug reactions (ADRs), and effectiveness. Results Safety was analyzed in 642 patients (494 EBC, 94 MBC, 54 MGC). Overall, 325 (50.6%) patients experienced 1316 AEs, and 550 ADRs occurred in 199 (31.0%) patients. Unexpected ADRs occurred in 62 (9.7%) patients. Unexpected ADRs and ADRs of special interest did not raise any new safety signals. Among trastuzumab-naïve patients, 34/106 (32.1%) with EBC achieved pathological complete response; 30/74 (40.5%) MBC and 24/49 (49.0%) MGC patients achieved complete or partial response. Conclusions In a real-world setting, CT-P6 demonstrated safety and efficacy findings consistent with previous CT-P6 studies.

Safety and effectiveness of certolizumab pegol in Japanese patients with rheumatoid arthritis: Up to 3-year results from a postmarketing surveillance study.

To report up to 3-year safety and effectiveness of certolizumab pegol (CZP) in Japanese patients with rheumatoid arthritis from a postmarketing surveillance study. Patients enrolled previously completed 24 weeks of CZP in the 24-week postmarketing surveillance study. Adverse drug reactions (ADRs) were recorded for patients who received ≥1 CZP dose. Effectiveness outcomes were 28-joint Disease Activity Score with erythrocyte sedimentation rate and European Alliance of Associations for Rheumatology response. Week 24-156 safety and Week 0-52 effectiveness data are reported here. A total of 781 patients were enrolled, with 735 and 376 patients evaluated for safety and effectiveness, respectively. Within the safety set, 17.8% (131/735) of patients reported ADRs; 9.4% (69/735) reported serious ADRs. Among patients with history of respiratory, thoracic, and mediastinal disorders, 38.4% (28/73) reported ADRs. The most frequent ADRs were infections and infestations (11.8%; 87/735); skin and subcutaneous tissue disorders (1.9%; 14/735); respiratory, thoracic, and mediastinal disorders (1.6%; 12/735). Mean 28-joint Disease Activity Score with erythrocyte sedimentation rate reduced from 4.6 (Week 0) to 2.8 (Week 52). At Week 52, 51.8% (161/311) of patients achieved European Alliance of Associations for Rheumatology Good response. The long-term safety and effectiveness of CZP in the real-world setting in Japan were consistent with previously reported data; no new safety signals were identified.

Five-year outcomes of the GORE VIABAHN Endoprosthesis for the treatment of complex femoropopliteal lesions from a Japanese postmarket surveillance study.

Introduction: The safety and effectiveness of the GORE VIABAHN Endoprosthesis for treatment of symptomatic patients with peripheral artery disease (PAD) and complex femoropopliteal (FP) lesions was assessed in a real-world Japanese practice setting. Methods: A prospective, multicenter, postmarket surveillance study was conducted from 2016 to 2017 at 64 sites in Japan. Symptomatic patients with PAD and FP lesions ⩾ 10 cm and reference vessel diameters ranging from 4.0 to 7.5 mm were eligible for enrollment. Outcome measures evaluated at 5 years were primary patency (PP), primary-assisted patency (PAP), secondary patency (SP), freedom from target lesion revascularization (fTLR), occurrence of device- or procedure-related serious adverse events (SAEs), and stent fractures. Results: A total of 321 patients were enrolled and were a mean age of 73.9 ± 8.7 years; 77.3% were men and 26.5% had chronic limb-threatening ischemia (CLTI). The mean lesion length was 23.6 ± 6.6 cm and the frequency with TASC II C/D lesions and chronic total occlusions was 86.6% and 70.4%, respectively. The Kaplan-Meier estimated PP, PAP, SP, and fTLR at 5 years was 62.4%, 74.1%, 82.3%, and 75.9%, respectively. The mean ankle-brachial index was 0.92 ± 0.15 and the mean improvement in Rutherford class was 2.3 ± 1.4, which was maintained through 5 years. The rate of cumulative device- or procedure-related SAEs through 5 years was 19.9% with only 9.3% of those occurring after the first year. No stent fractures were observed through 5 years by x-ray evaluation. Conclusion: The 5-year safety and efficacy outcomes of the endoprosthesis were clinically acceptable for treating complex FP lesions in a real-world cohort of Japanese patients with PAD.

Effectiveness of Ixekizumab in Chinese Patients with Moderate-Severe Plaque Psoriasis with Special Area Involvement: Subanalysis of a Prospective, Multicenter, Observational Real-World Study.

Ixekizumab, a monoclonal antibody against interleukin-17A, demonstrated effectiveness in the treatment of psoriasis in a Chinese real-world study that was consistent with previous randomized controlled trials. Here, we report further analyses from this study to explore the effectiveness of ixekizumab for treating patients with psoriasis and the involvement of special body areas (scalp, nail, joint, palmoplantar, or genital areas). A multicenter, prospective, observational, single-arm, post-marketing surveillance study was conducted in patients aged ≥ 18years with moderate-to-severe plaque psoriasis and prescribed with ixekizumab in 26 Chinese hospitals. Psoriasis Area and Severity Index (PASI) and Dermatology Life Quality Index (DLQI) scores were compared between patients with versus without psoriasis in special body areas in the overall study population and across subgroups by body area. In total, 612 patients were included. At baseline, most patients (93.6%) had psoriasis involvement in at least one special body area. Overall, patients with psoriasis in special body areas reported a worse quality of life (QoL) than those without. Patients with versus without psoriasis in special body areas achieved a comparable mean reduction from baseline in PASI score (10.9 vs. 9.2 at week2, and 16.9 vs. 14.7 at week12, respectively) and DLQI score (6.0 vs. 4.4 at week2, and 9.9 vs. 7.5 at week12, respectively); a similar proportion of patients also achieved PASI50 at week2, and PASI75 and PASI90 at week12, and a DLQI (0/1) at weeks2 and 12. Several significantly different results were reported between subgroups, the majority of which favored patients with special body area involvement. Most patients had psoriasis involvement in a special body area which was associated with worse QoL. Ixekizumab is similarly effective in reducing disease severity and improving QoL in patients with plaque psoriasis across different special body areas.

A Systematic Review of Naldemedine and Naloxegol for the Treatment of Opioid-Induced Constipation in Cancer Patients.

Opioid-induced constipation (OIC) is a pervasive and distressing side effect of chronic opioid therapy in patients with cancer pain, significantly impacting their quality of life. Peripherally acting μ-opioid receptor antagonists (PAMORAS) were developed for treatment-resistant OIC but most studies were conducted with non-cancer patients. to discuss two oral formulations of PAMORAs, naldemedine and naloxegol, and to review available evidence of the effectiveness of these drugs for OIC in cancer patients. a comprehensive search to identify primary literature for either naldemedine or naloxegol for OIC in cancer patients. Only three prospective randomized, double-blind, placebo-controlled clinical trials for naldemedine enrolling cancer patients were identified; the results of a subgroup analysis of two of those studies and two non-interventional post marketing surveillance studies of these trials are also reported here. For naloxegol, only two randomized controlled trials were identified; both were unsuccessful in enrolling sufficient patients. An additional four prospective non-interventional observational studies with naloxegol were found that enrolled cancer patients. There were significantly higher rates of responders in the PAMORA groups than in the placebo groups. The most common side effect for both PAMORAs was diarrhea. All studies were industry-funded, and given that only three trials were randomized controlled studies, the overall quality of the studies was lacking. Naldemedine or naloxegol appeared safe and useful in the treatment of OIC in cancer patients and may improve their quality of life. Larger-scale randomized placebo-controlled studies of PAMORAs in cancer patients would strengthen existing evidence.

Post-Marketing Surveillance of the World's First Novel Cocktail of Rabies Monoclonal Antibodies: TwinRab™ in Real \-World Setting.

Rabies presents with a high fatality rate, which imposes a significant global public health challenge, and therefore the use of post-exposure prophylaxis (PEP) is crucial for prevention. Monoclonal antibodies (mAbs) have emerged as a promising substitute for rabies immunoglobulins (RIGs) due to their high efficacy and standardized manufacturing process. A prospective, open-label, post-marketing surveillance study (PMS) was conducted at Byramjee Jeejeebhoy Medical College (BJMC), Pune. The study included patients aged more than 2 years who had recently sustained Category III-suspected rabid animal bite exposures. These patients were administered TwinRabTM at a dosage of 40 IU/kg in and around the wound as intralesional transfer, along with the anti-rabies vaccine (ARV). Adverse events (AEs) grading was performed with reference to the Food and Drug Administration (FDA) toxicity grading. In this study, 215 subjects received the TwinRabTM mAb with a 100% completion rate. Out of 215 patients, three (1.3%) patients in the range of 18 to 65 years of age showed solicited local AEs, which were resolved after the appropriate treatment intervention, but causality assessment was non-assessable. The overall tolerability assessment showed positive ratings from doctors (91.63%) and patients (67.91%) for the mAb cocktail. The PMS demonstrated the safety of TwinRabTM in patients who experienced Category III-suspected rabid animal bites, thereby supporting its potential as an alternative option for post-exposure prophylaxis in the management of animal bites for the prevention of rabies.
