Long-term efficacy and safety of cannabidiol in patients with tuberous sclerosis complex: 3-year results from the cannabidiol expanded access program.

The cannabidiol (CBD) Expanded Access Program provided compassionate access to CBD for patients with treatment-resistant epilepsy, including tuberous sclerosis complex (TSC), at 35 US epilepsy centers. Here, we present the long-term efficacy and safety outcomes for add-on CBD treatment in patients with TSC. Patients received plant-derived, highly purified CBD (Epidiolex® 100 mg/mL, oral solution), increasing from 2 to 10 mg/kg/d to tolerance or maximum of 25-50 mg/kg/d. Efficacy endpoints were percentage change from baseline in median monthly convulsive, focal, and total seizure frequency and ≥ 50%, ≥75%, and 100% responder rates across 12-week visit windows through 144 weeks. Adverse events (AEs) are reported through 233 weeks. Thirty-four patients with confirmed TSC were included. Mean age was 12.4 years (range, 1.8-31.2), and patients were receiving a median of 3 (range, 1-7) antiseizure medications (ASMs) at baseline. Median CBD dose was 25-28 mg/kg/d for 36 weeks and then 20-50 mg/kg/d through 228 weeks. Dose reduction from baseline occurred for most ASMs, except topiramate. Median reduction in the frequency of convulsive, focal, and total seizures was 44%-81%, 51%-87%, and 44%-87%, respectively, through 144 weeks. Responder rates (≥50%, ≥75%, and 100% reduction) were 43%-71%, 14%-58%, and 0%-25% for convulsive seizures; 52%-75%, 35%-60%, and 7%-32% for focal seizures; and 46%-79%, 26%-65%, and 0%-13% for total seizures. A total of 94% of patients experienced ≥1 AE; 47% had serious AEs, considered treatment unrelated by the investigator. Treatment-related AEs (TRAEs) occurred in 71% of patients. The most frequently reported TRAEs were somnolence, diarrhea, and ataxia. Two patients experienced AEs leading to discontinuation. There were no deaths. Long-term add-on CBD use was associated with reduced seizure frequency through 144 weeks. The safety profile was consistent with previous reports. In this study, we evaluated efficacy and safety of cannabidiol (CBD) treatment in patients with tuberous sclerosis complex receiving CBD in addition to other antiseizure treatments in an Expanded Access Program. After starting CBD, 46%-79% of patients had at least 50% reduction and 26%-65% had at least 75% reduction in the number of seizures per month; up to 13% had no seizures through 144 weeks. Safety results were similar to prior studies; sleepiness and diarrhea were common treatment-related side effects. These results show that long-term CBD treatment was associated with fewer seizures and mild/moderate side effects.

Real-World Outcomes of Patients With Malignant Pleural Mesothelioma Receiving a Combination of Ipilimumab and Nivolumab as First- or Later-Line Treatment

ObjectivesOn the basis of the positive results of CheckMate-743, first-line (1L) treatment of malignant pleural mesothelioma (MPM) with the combination of ipilimumab and nivolumab (ipi/nivo) has become a standard-of-care. Furthermore, patients who received 1L platinum/pemetrexed chemotherapy are often considered for second or further-line (2L+) ipi/nivo on the basis of MAPS2 results. Here we report on real-world survival and safety outcomes of ipi/nivo for patients with MPM in Switzerland. MethodsTwelve cancer centers contributed data to this retrospective cohort. Baseline characteristics including age, sex, histology, programmed death-ligand 1 expression, Eastern Cooperative Oncology Group performance status (ECOG PS), and previous/subsequent therapies were collected. The efficacy and safety outcomes were assessed by local investigators. ResultsOf the 109 patients with MPM treated with ipi/nivo between November 2017 and March 2023 (median follow-up of 16.6 months) 75% had epithelioid, 9% biphasic, and 16% sarcomatoid histology. The median age was 72 years; 91% were males, and 83% had an ECOG PS of 0 to 1. Ipilimumab in combination with nivolumab was given as 1L in 43% and as 2L+ treatment in 57% of patients. The objective response rate was 21% in 1L and 15% in 2L+. Median progression-free survival was 6.5 and 2.8 months, respectively. Median overall survival (OS) from the start of ipi/nivo was 12.6 months for 1L and 6.9 months for 2L+. No differences in OS were observed depending on age and programmed death-ligand 1 expression. Nevertheless, the median OS was significantly worse in patients with an ECOG PS of 2 or higher than those with an ECOG PS of 0 to 1 (2.4 versus 11.9 months, p < 0.001). Treatment-related adverse events (TRAEs) of any grade related to ipi/nivo treatment occurred in 65 patients (62%). The highest-grade TRAE was 1 to 2 in 58% of these patients and 3 or higher in 42% Treatment discontinuation due to a TRAE occurred in 22% of patients. ConclusionIn this real-world cohort of patients with MPM treated with ipi/nivo survival outcomes were inferior to those reported in the CheckMate-743 and MAPS2 trials, whereas safety outcomes were similar.

The role of calcium homeostasis in modulating the immune response in cancer and infectious diseases

Calcium homeostasis is a pivotal determinant of physiological processes, particularly in cellular signaling and immune system regulation. This balance is crucial for modulating immune responses in the context of both infectious and oncological diseases. Disruptions in calcium homeostasis have been shown to influence disease progression, immune efficacy, and treatment outcomes. Our study investigates the critical role of calcium homeostasis in shaping the immune response to cancer and infectious diseases through a comprehensive literature review. The electronic databases Scopus, Google Scholar, and PubMed were utilized to gather relevant studies, identified using key terms such as "calcium homeostasis," "immune response," "cancer," and "infectious diseases." Emerging evidence underscores that calcium levels directly impact immune cell function, including the activation of immune effector cells, cytokine production, and the orchestration of the overall immune response. These processes are critical to the body's ability to combat infections and malignancies. Aberrant calcium signaling may lead to compromised immune defense mechanisms, negatively affecting the outcomes of therapeutic interventions. In cancer, for example, altered calcium homeostasis can suppress immune surveillance, while in infectious diseases, it can hinder the immune system's capacity to clear pathogens. Our review highlights that the pathophysiology of both cancer and infectious diseases is tightly interwoven with calcium regulation, suggesting a promising avenue for therapeutic targeting. Modulating calcium homeostasis may enhance immune functionality, thereby improving treatment efficacy. By restoring calcium balance, novel therapeutic approaches could be developed to optimize immune responses and bolster clinical outcomes across a range of diseases. Further research is warranted to elucidate the precise molecular mechanisms linking calcium homeostasis and immune regulation, with the goal of refining future therapeutic strategies. Maintaining calcium equilibrium is thus essential for the advancement of effective treatments in both cancer and infectious disease contexts.

Prostacyclin pathway vasodilators in patients with chronic thromboembolic pulmonary hypertension (CTEPH): A systemic review and meta-analysis of randomized controlled trials.

Although surgical and interventional therapy has emerged as the primary treatment for patients with chronic thromboembolic pulmonary hypertension (CTEPH), there remains a subset of patients who need medication therapy. This study aimed to evaluate the efficacy and safety outcomes of prostacyclin pathway vasodilators, providing further insight for clinical decision-making. A literature search was conducted in PubMed, Embase, and CENTRAL databases from inception to December 2023. Literature screening and quality assessment were carried out with the Cochrane Risk of Bias Tool. Data analysis was conducted using RevMan 5.4 software. We included 6 randomized controlled trials with 387 patients. Prostacyclin pathway vasodilators demonstrated a significant improvement in PVR (-125.26 dynes·sec·cm-5, 95%CI: -219.29 to -31.23, Z = 2.61, and p < 0.009), RAP (-0.78 mmHg, 95%CI: -1.52 to -0.04, Z = 2.06, and p = 0.04), cardiac index (0.62, 95%CI: 0.54 to 0.69, Z = 16.13, and p < 0.00001), and the number of patients showing improvement in WHO functional class (3.86, 95%CI: 1,92 to 7.77, Z = 3.79, and p = 0.0002) compared to controls, moreover, a trend towards improvement was observed in mPAP, 6MWD, and NT-proBNP. Regarding the safety endpoints, no significant difference was found in both groups in terms of serious adverse events and all-cause deaths. The prostacyclin pathway vasodilators present therapeutic potential for CTEPH patients with inoperable or persistent/recurrent PH after PEA/BPA primarily characterized by distal small-vessel and microvasculopathy. However, the current clinical evidence remains insufficient and controversial, necessitating further validation.

No Impact of Concomitant Medications on Efficacy and Safety of Biologics and Small Molecules for Ulcerative Colitis

While participants with inflammatory bowel diseases (IBD) in clinical trials of biologics and small molecule drugs (henceforth, advanced therapies) frequently receive several medications concomitantly, it is unclear how they modify treatment effect. Through an individual patient data pooled analysis of ten clinical trials of advanced therapies for moderate-to-severe ulcerative colitis (UC), we assessed whether concomitant exposure to corticosteroids, immunomodulators, 5-aminosalicylates, proton pump inhibitors (PPIs), histamine receptor antagonists (H2RA), opiates, antidepressants, and antibiotics modified the effect of the intervention on treatment efficacy and safety outcomes, using modified Poisson regression model. Of 6044 patients (4280 receiving intervention, 1764 receiving placebo), several received concomitant corticosteroids (47%), immunomodulators (28%), 5-aminosalicylates (68%), PPIs (14%), H2RAs (2%), opiates (7%), antidepressants (6%), and/or antibiotics (5%). After adjusting for confounders and examining treatment efficacy of intervention vs. placebo, we observed no impact of concomitant exposure to corticosteroids (ratio of relative risk of drug vs. placebo with vs. without concomitant exposure: RRR, 0.81 [95% CI,0.63-1.06], 5-aminosalicylates (RRR, 1.04[0.78-1.39]), PPIs (RRR, 0.87 [0.61-1.22]), H2RAs (RRR, 1.72[0.97-14.29]), opiates (RRR, 0.90[0.54-1.49]), antidepressants (RRR, 1.02[0.57-1.83]), and antibiotics (RRR, 0.72[0.44-1.16]) on likelihood of clinical remission. Concomitant exposure to immunomodulators was associated with lower likelihood of achieving clinical remission (RRR, 0.73[0.55-0.97]), particularly with non-TNF antagonists. In clinical trials of advanced therapies for UC, baseline concomitant exposure to multiple commonly used class of medications does not impact treatment efficacy or safety. These findings directly inform design of regulatory clinical trials with respect to managing concomitant medications at baseline.

Outcomes of Dose Escalation of Imatinib in Chronic Myeloid Leukemia Patients: A Retrospective Analysis From an Indian University Teaching Hospital.

Chronic myeloid leukemia (CML) treatment in low- and middle-income countries faces significant financial and logistical constraints. In scenarios where second-line tyrosine kinase inhibitors (TKIs) are unavailable or unaffordable, dose escalation of imatinib provides an alternative. This study evaluates the efficacy, safety, and progression-free survival (PFS) outcomes of dose escalation of imatinib in CML patients who experienced suboptimal response or progression on standard doses. A retrospective analysis of 123 CML patients treated at an Indian university teaching hospital from 2013 to 2016 was conducted. Patients who showed progression on a 400 mg dose of imatinib were escalated to 600 mg, and further to 800 mg if required. Demographic data, progression, and toxicity were analyzed. Out of 123 patients, 78 (63.4%) showed a complete hematologic response after dose escalation. The median PFS was 48 months, with a three-year PFS rate of 67%. Notable toxicities included Grade 3/4 neutropenia in 15% and gastrointestinal disturbances in 12%. Comparatively, studies suggest that switching to a second-line TKI in similar settings results in a higher PFS; however, our findings underscore that dose escalation of imatinib remains a viable alternative when financial constraints limit access to second-line therapies. In resource-constrained settings, dose escalation of imatinib can be an effective strategy for managing CML patients who progress on standard doses.

Unilateral and bilateral radioactive stent insertion in patients diagnosed with inoperable hilar cholangiocarcinoma: a comparative analysis.

While hilar cholangiocarcinoma (HCCA) patients commonly undergo radioactive stent (RS) insertion treatment, the relative benefits of unilateral versus bilateral RS insertion procedures remain to be established. Accordingly, this study was designed to evaluate the relative safety and efficacy of percutaneous bilateral and unilateral RS insertion for patients with HCCA. In total, 126 HCCA patients who underwent unilateral (n=64) or bilateral (n=62) RS insertion from January 2017 - December 2021 were included in this analysis. Treatment efficacy and long-term outcomes were compared between groups. The primary endpoint was stent patency, and the secondary endpoints included technical success rate, clinical success rate, local control rate, overall survival (OS), and complications. The respective technical success rates in the unilateral and bilateral groups were 90.6% (58/64) and 93.5% (58/62) (P = 0.782). The clinical success rates were 82.8% and 86.2% in unilateral and bilateral groups, respectively (P = 0.608). Both groups exhibited comparable medial post-intervention bilirubin levels (100 vs. 99 μmol/L; P = 0.501), and restenosis occurred in 12 (20.7%) and 15 (25.9%) patients over the follow-up interval (P = 0.510). The stent reintervention rate was significantly higher in the unilateral group than bilateral group (66.7% vs. 0.0%, P < 0.001). The median stent patency in the unilateral and bilateral groups was 189 and 210 days, respectively (P = 0.796), while the median OS interval was 222 and 229 days, respectively (P = 0.969). Comparable cholangitis (17.2% vs. 22.4%, P = 0.485) and cholecystitis (3.4% vs. 3.4%, P = 1.000) rates were also detected in these two groups. In summary, HCCA patients exhibit comparable efficacy when undergoing unilateral and bilateral radioactive stenting, suggesting that unilateral RS can be routinely performed owing to the simpler nature of this procedure.

CRISPR/Cas9 in the treatment of sickle cell disease (SCD) and its comparison with traditional treatment approaches: a review.

Sickle cell disease (SCD) is a common hereditary blood disorder that profoundly impacts individuals' health, causing chronic pain, anemia, organ damage, increased susceptibility to infections, and social and psychological effects. Over the years, advances in treatment have improved the long-term outcomes of SCD patients. However, problems such as limited access to hematopoietic stem cell transplantation (HSCT) and potential complications associated with the available therapies underscore the importance of continued research and development. The recent FDA approval of Casgevy (Exagamglogene autotemcel), a genetic therapy based on CRISPR/Cas9 technology, demonstrates a comprehensive effort to address the complexity of SCD using new technologies. This review explores the potential of CRISPR/Cas9 for treating SCD and evaluates its efficacy, safety, and long-term outcomes compared to traditional treatment approaches. Long-term research is needed to comprehensively assess the safety, effectiveness, and inclusion of CRISPR/Cas9, ensuring its overall efficacy.

Dual antiplatelet therapy duration and stent type in patients with high bleeding risk: A systematic review and network meta-analysis

BackgroundIt is uncertain whether the efficacy and safety of dual antiplatelet therapy (DAPT) in patients with high bleeding risk (HBR) vary according to DAPT duration and stent type (e.g., durable polymer drug-eluting stents (DP-DESs), biodegradable polymer DESs (BP-DESs), or polymer-free drug-coated stents (PF-DCSs)). We aimed to study the stent type and DAPT duration appropriate for patients with HBR. MethodsPubMed and EMBASE were searched until October 2023. Randomized controlled trials (RCTs) involving patients with HBR that compared standard DAPT (6-12 months) with DP- or BP-DES versus short DAPT (≤3 months) with DP- or BP-DES or PF-DCS or bare-metal stent (BMS) were identified. The primary efficacy outcome was major adverse cardiovascular events (MACEs), defined as cardiovascular death, myocardial infarction (MI), and stroke. The primary safety outcome was major bleeding. Secondary outcomes included MI and stent thrombosis (ST). We performed a network meta-analysis using a random effects model. ResultsThirteen RCTs with a total of 19,418 patients with HBR were included. Compared to standard DAPT with DP-DES, short DAPT with BMS was associated with a higher risk of MACE and MI. For major bleeding, short DAPT strategies were associated with a lower risk than standard DAPT strategies (e.g. short DAPT with DP-DES versus standard DAPT with DP-DES; HR[95% CI]: 0.48[0.28-0.82]). Interestingly, the use of BP-DES was associated with a higher risk of ST than DP-DES (e.g. standard DAPT with BP-DES versus short DAPT with DP-DES; HR[95% CI]: 2.65[1.03-6.79]). ConclusionsIn patients with HBR who underwent percutaneous coronary intervention, a short DAPT strategy with DP-DES should be used since it offers the best combination of efficacy and safety.

IPECAD Modeling Workshop 2023 Cross-Comparison Challenge on Cost-Effectiveness Models in Alzheimer’s Disease

ObjectivesDecision-analytic models assessing the value of emerging Alzheimer’s disease (AD) treatments are challenged by limited evidence on short-term trial outcomes and uncertainty in extrapolating long-term patient-relevant outcomes. To improve understanding and foster transparency and credibility in modeling methods, we cross-compared AD decision models in a hypothetical context of disease-modifying treatment for mild cognitive impairment (MCI) due to AD. MethodsA benchmark scenario (US setting) was used with target population MCI due to AD and a set of synthetically generated hypothetical trial efficacy estimates. Treatment costs were excluded. Model predictions (10-year horizon) were assessed and discussed during a 2-day workshop. ResultsNine modeling groups provided model predictions. Implementation of treatment effectiveness varied across models based on trial efficacy outcome selection (clinical dementia rating – sum of boxes, clinical dementia rating – global, mini-mental state examination, functional activities questionnaire) and analysis method (observed severity transitions, change from baseline, progression hazard ratio, or calibration to these). Predicted mean time in MCI ranged from 2.6 to 5.2 years for control strategy and from 0.1 to 1.0 years for difference between intervention and control strategies. Predicted quality-adjusted life-year gains ranged from 0.0 to 0.6 and incremental costs (excluding treatment costs) from −US$66 897 to US$11 896. ConclusionsTrial data can be implemented in different ways across health-economic models leading to large variation in model predictions. We recommend (1) addressing the choice of outcome measure and treatment effectiveness assumptions in sensitivity analysis, (2) a standardized reporting table for model predictions, and (3) exploring the use of registries for future AD treatments measuring long-term disease progression to reduce uncertainty of extrapolating short-term trial results by health-economic models.

Efficacy of problem-solving therapy in treating late-life depression with potential cognitive impairment: a systematic review and meta-analysis.

Late-life depression (LLD) is a global public health issue, often accompanied by cognitive impairments that can exacerbate the severity of depression and impair social functioning. Despite being a well-established treatment for LLD, the suitability of problem-solving therapy (PST) for individuals with LLD and varying degrees of cognitive impairments warrants further investigation. This paper presents the protocol for a systematic review and meta-analysis of randomised controlled trials (RCTs) aimed at evaluating the effectiveness and acceptability of PST for this specific demographic. Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, we will conduct a systematic review to synthesise existing research on PST for individuals in this demographic. We will comprehensively search multiple databases and sources, including PubMed, EMBASE, the Cochrane Database and APA PsycNET from inception to October 2023, without language, publication year or type restrictions. Relevant studies will be manually screened from the references. Only RCTs involving PST for LLD will be included. The primary efficacy outcome will be the standardised mean difference in total scores on continuous depression severity scales across different comparison arms. Data extraction will be conducted independently by two reviewers (CH and J-JW), and methodological rigour will be assessed using the Cochrane Risk of Bias assessment tool. Subgroup and sensitivity analyses will be performed to investigate the impact of concomitant cognitive impairments and to evaluate the robustness of the findings. The meta-analysis project is expected to be ethically unproblematic and does not require approval from a research ethics committee. The results of this study will be shared through articles in scholarly peer-reviewed journals and presentations in various formats, both print and digital. CRD42023473782.

Efficacy and Safety of Transcranial Direct Current Stimulation as an Add-On Trial Treatment for Acute Bipolar Depression Patients With Suicidal Ideation.

Bipolar depression poses an overwhelming suicide risk. We aimed to examine the efficacy and safety of transcranial direct current stimulation (tDCS) combined with quetiapine in bipolar patients as a suicidal intervention. In a single-center, double-blind, treatment-naive bipolar depression patients with suicidal ideation were randomly assigned to quetiapine in combination with either active (n = 16) or sham (n = 15) tDCS over the left dorsolateral prefrontal cortex for three consecutive weeks. The 30-min, 2-mA tDCS was conducted twice a day on the weekday of the first week and then once a day on the weekdays of the two following weeks. Primary efficacy outcome measure was the change in the Beck Scale for Suicidal Ideation (BSSI). Secondary outcomes included changes on the 17-item Hamilton Depression Rating Scale (HDRS-17) and Montgomery-Asberg Depression Rating Scale (MADRS). Outcome was evaluated on Day 3 and weekend. Safety outcome was based on the reported adverse reactions. Active tDCS was superior to sham tDCS on the BSSI at Day 3 and tended to sustain every weekend during the treatment process, compared to baseline. However, no difference between active and sham in HDRS-17 and MADRS was found. Response and remission rate also supported the antisuicide effect of tDCS, with higher response and remission rate in BSSI, but no antidepressant effect, compared to sham, over time. Regarding safety, active tDCS was well tolerated and all the adverse reactions reported were mild and limited to transient scalp discomfort. The tDCS was effective as an antisuicide treatment for acute bipolar depression patients with suicidal ideation, with minimal side effects reported.

Safety and Effectiveness Analysis of Endovascular Treatment versus Standard Medication Treatment in Patients with Progressive Acute Ischemic Stroke with Large Vessel Occlusion Stroke in the Ultra-Late Time Window: A Propensity Score Matched Cohort Study

The time from onset to symptom deterioration in ischemic stroke often exceeds 24hours, and this ultra-late time window is excluded from the endovascular treatment (EVT) guideline. This study aimed to explore the safety and efficacy of EVT in progressive acute ischemic stroke with large vessel occlusion stroke patients with onset to symptom deterioration times of 24 hours-7days. Progressive stroke patients with time window of 24 hours-7days treated at our hospital over the past 6years were retrospectively collected. Patients were categorized into EVT and standard medication treatment (SMT) groups based on the treatment approach. Patients were matched using propensity score matching. Safety outcomes primarily included 3-month mortality and symptomatic intracranial hemorrhage; efficacy outcome primarily included functional independence (3-month modified Rankin scale≤2). A total of 396 patients were included in the study, with 86 (21.7%) in EVT and 310 (78.3%) in SMT group. There were 140 remaining after propensity score matching, with 70 in each group (50%). Compared to SMT group, EVT group had higher functional independence (52.9% vs. 15.7%, odds ratio [OR]=7.504, 95% confidence interval [CI] 2.141-14.093, P < 0.001) and lower 3-month mortality (14.3% vs. 40.0%, OR=0.412, 95% CI 0.099-0.856, P < 0.001). EVT was also associated with higher symptomatic intracranial hemorrhage (25.7% vs. 5.7%, OR=9.926, 95% CI 1.874-36.547, P < 0.001). For patients with progressive acute ischemic stroke with large vessel occlusion in the ultra-late time window, EVT remains a viable treatment approach.

Intensive Home Blood Pressure Lowering in Patients with Advanced CKD

Optimal blood pressure (BP) targets in advanced CKD are controversial. More intensive BP lowering in the setting of advanced CKD is thought to be associated with risk of acute kidney injury, hyperkalemia, and ESKD. We aimed to conduct a pilot trial of intensive BP control to determine if lower SBP targets can be safely achieved for patients with CKD through titration of BP medications using in-home measured BP. Non-blinded randomized controlled trial. 108 patients with advanced CKD (eGFR ≤30 mL/min/1.73 m2) and hypertension. Participants were randomized either to a target home SBP goal of <120 mmHg (N=66) or a less intensive SBP goal (N=42). Antihypertensive medications were titrated to achieve the target home SBP range in the first 4 months of the study and maintained until the end of the study. Home BP was measured using a wireless Bluetooth-enabled monitor that transmitted readings to providers in real-time. The primary efficacy outcome was the difference in achieved clinic SBP between the two study arms from months 4-12. Safety outcomes included hyperkalemia, a composite outcome of falls or syncope, and onset of need for dialysis or kidney transplantation. The mean clinic SBP at month 12 was 124.7 mmHg in the intensive SBP group vs. 138.2 mmHg in the less intensive SBP group. Averaged over months 4-12, the achieved mean clinic SBP in the intensive SBP arm was 11.7 mmHg (95% CI 7.5 to 16 mmHg, p<0.001) lower than the mean SBP achieved in the less intensive SBP arm. Primary safety outcomes were not statistically significantly different between the two arms (all p>0.05). Small sample size which may limit our ability to detect clinically significant differences in rates of adverse outcomes; single-center design. A clinic SBP goal of <120 mmHg is feasible to achieve with the help of real-time home BP monitoring and appears to be safe in this study population with advanced CKD. Larger trials to determine optimal BP targets in advanced CKD and the risks and benefits associated with more intensive BP control are warranted.

Comparative Efficacy and Safety of Upadacitinib vs. Vedolizumab, Ustekinumab, and Tofacitinib After Induction and Maintenance for Ulcerative Colitis: Three Matching-Adjusted Indirect Comparisons.

Evidence on the comparative efficacy and safety of approved therapies for ulcerative colitis (UC) during induction and maintenance, including upadacitinib (UPA), vedolizumab (VEDO), ustekinumab (UST), and tofacitinib (TOFA), is limited. Using data from phase 3 trials, three placebo (PBO)-anchored matching-adjusted indirect comparisons of the efficacy and safety of UPA versus VEDO, UST, and TOFA (U-ACHIEVE and U-ACCOMPLISH, GEMINI-1, UNIFI, and OCTAVE induction and maintenance trials) have been conducted. Baseline characteristics from UPA trials were weighted separately to match each comparator trial. Induction responders were re-randomized to oral UPA 15 or 30mg, VEDO 300mg intravenously every 8weeks (Q8W), UST 90mg SC Q8W, or oral TOFA 5mg, or PBO in maintenance. Treat-through efficacy outcomes at weeks 44(UST)/46(VEDO)/52(UPA/TOFA) were adjusted by the likelihood of induction response and included clinical response, clinical remission, and endoscopic improvement. Safety outcomes included adverse events (AEs), serious AEs (SAEs), and AEs leading to discontinuation (except UPA vs. VEDO). Benefit-risk was assessed by numbers needed to treat (NNT)/harm, calculated as the inverse of the difference in proportions of patients achieving each efficacy/safety outcome for UPA versus comparator. The proportions of patients who demonstrated clinical response or endoscopic improvement was greater with UPA 15mg versus VEDO and TOFA (p<0.05). The proportions of patients demonstrating all treat-through efficacy outcomes were significantly greater with UPA 30mg versus VEDO, UST, or TOFA with NNTs 3.2-8.7. No significant differences in proportions of AEs, SAEs, and AEs leading to discontinuation were observed between the two doses of UPA and comparators. In patients with active UC, greater clinical efficacy, and similar safety after 1year of maintenance were observed with UPA versus VEDO, UST, and TOFA, suggesting a favorable benefit-risk profile for UPA. Despite matched baseline characteristics, differences in trial design and endpoints may persist.

Long-term efficacy and safety of two short standardised regimens for the treatment of rifampicin-resistant tuberculosis (STREAM stage 2): extended follow-up of an open-label, multicentre, randomised, non-inferiority trial

STREAM stage 2 showed that two bedaquiline-containing regimens (a 9-month all-oral regimen and a 6-month regimen with 8 weeks of aminoglycoside) had superior efficacy to a 9-month injectable-containing regimen for rifampicin-resistant tuberculosis up to 76 weeks after randomisation. Our objective in this follow-up analysis was to assess the durability of efficacy and safety, including mortality, at 132 weeks. We report the long-term outcomes from STREAM stage 2, a randomised, phase 3 non-inferiority (10% margin) trial in participants (aged ≥15 years) with rifampicin-resistant tuberculosis without fluoroquinolone or aminoglycoside resistance at 13 clinical sites in seven countries (Ethiopia, Georgia, India, Moldova, Mongolia, South Africa, and Uganda). Participants were randomly assigned 1:2:2:2 (via permuted blocks and stratified by site and HIV status plus CD4 cell count) to the 2011 WHO long regimen (terminated early), a 9-month control regimen, a 9-month oral regimen with bedaquiline (primary comparison), or a 6-month regimen with bedaquiline and 8 weeks of an injectable antituberculous drug. Participants and clinicians were aware of treatment-group assignments, but laboratory staff were masked. The primary outcome, reported previously, was favourable status (negative cultures for Mycobacterium tuberculosis without a preceding unfavourable outcome; any death, bacteriological failure or recurrence, and major treatment change were considered unfavourable) at week 76. Here we report efficacy outcomes at week 132, analysed in the modified intention-to-treat (mITT) population. Safety assessments continued to 132 weeks and were in all participants who received at least one dose of the study regimen. All comparisons used concurrently randomised participants. This trial is registered on ISRCTN (ISRCTN18148631) and is now completed. Between March 28, 2016, and Jan 28, 2020, 588 participants were randomly assigned to the long (n=32), control (n=202), oral (n=211), or 6-month (n=143) treatment regimens; 352 (60%) were male and 236 (40%) were female. Of the 556 participants on the three shorter regimens, 517 were included in the mITT population (187 in control group, 196 in oral group, and 134 in 6-month group) and 465 in the per-protocol analyses. Six additional participants had an unfavourable outcome that occurred between week 76 and the end of efficacy follow-up (one in control group, four in oral group, one in 6-month group). In the mITT population, the proportion of patients with an unfavourable outcome at the end of follow-up was 19·6% (95% CI 14·3 to 24·9) in the oral group and 29·3% (23·3 to 36·5) in the control group (-9·7 percentage points difference [95% CI -18·7 to -1·8]; psuperiority=0·024). An estimated 9·8% (95% CI 4·6 to 14·9) of participants on the 6-month regimen had an unfavourable outcome, which was significantly lower than for those concurrently on the control regimen (32·5% [23·7 to 40·2]; psuperiority<0·0001) or the oral regimen (23·8% [16·9 to 31·1]; psuperiority=0·013). Few serious or severe adverse events were reported after week 76, with no indication of a difference between the regimens. At week 132, treatment-emergent hearing loss was recorded in significantly fewer participants on the oral regimen (7/205; 3%) than the control regimen (16/198; 8%; p=0.041); there was no significant difference in severe hearing loss between the oral regimen (6/139; 4%) and the 6-month regimen (5/143; 4%; p=0·72). Death rates were low: 1·01 (95% CI 0·48 to 2·12) per 100 person-years in participants allocated to bedaquiline (ie, oral and 6-month regimen, n=287) compared with 1·52 (0·63 to 3·66) in participants on the control regimen (n=140; p=0·49). Both of the bedaquiline-containing regimens maintained superiority to the control regimen, without evidence of increased mortality, providing two additional evidence-based treatment options for patients; previous mortality concerns for bedaquiline were not substantiated.

Impact of docetaxel plus ramucirumab therapy on interstitial lung disease in recurrent advanced non-small cell lung cancer patients.

Few studies have examined the safety and efficacy of docetaxel/ramucirumab (DOC/RAM) therapy in advanced non-small cell lung cancer (NSCLC) complicated by interstitial lung disease (ILD). Given the potential of vascular endothelial growth factor inhibitors to prevent drug-induced pneumonia, we aimed to clarify the role of this therapy in NSCLC with ILD. This retrospective observational study evaluated the incidence of ILD in stage IV NSCLC patients receiving DOC/RAM therapy at our institution, stratified by ILD status. We also assessed the efficacy of this treatment. The primary objective was to investigate the incidence of ILD, while secondary objectives included evaluating the objective response rate (ORR), progression-free survival (PFS), and overall survival (OS), stratified by ILD status. Among patients with pre-existing ILD, 7 out of 28 (25%) developed DOC/RAM-induced interstitial pneumonia, while none of the 40 patients without pre-existing ILD developed this condition (P<0.001). Comparing historical controls (DOC only) with the DOC/RAM group, RAM did not significantly alter the incidence of interstitial pneumonia (P=0.33). There were no significant differences in ORR, PFS, or OS between patients with and without ILD. Subgroup analysis of smokers showed a non-significant trend toward worse survival in those with pre-existing ILD (P=0.20). DOC/RAM therapy significantly increased the incidence of interstitial pneumonia in NSCLC patients with pre-existing ILD but did not significantly affect efficacy outcomes such as ORR, PFS, or OS.
