Long-term safety and efficacy of adalimumab for intestinal Behcet's disease in the open label study following a phase 3 clinical trial.

ABSTRACT: BACKGROUND/AIMS:Intestinal Behçet's disease (BD) is an immune-mediated inflammatory disorder. We followed up the patients and evaluated safety profile and effectiveness of adalimumab for the treatment of intestinal BD through 100 weeks rolled over from the 52 week clinical trial (NCT01243671). METHODS:Patients initiated adalimumab therapy at 160 mg at week 0, followed by 80 mg at week 2, followed by 40 mg every other week until the end of the study. Long-term safety and all adverse events (AEs) were examined. The efficacy was assessed on the basis of marked improvement (MI) and complete remission (CR) using a composite efficacy index, which combined global gastrointestinal symptoms and endoscopic assessments. RESULTS:Twenty patients were enrolled in this study; 15 patients received adalimumab treatment until study completion. The incidence of AEs through week 100 was 544.4 events/100 person-years, which was comparable to the incidence through week 52 (560.4 events/100 person-years). No unexpected trend was observed and adalimumab was well tolerated. At weeks 52 and 100, 60.0% and 40.0% of patients showed MI, respectively, and 20.0% and 15.0% of patients showed CR, respectively. CONCLUSIONS:This report demonstrates 2 years safety and effectiveness of adalimumab in intestinal BD patients. Patients with intestinal BD refractory to conventional treatment receiving up to 2 years of adalimumab treatment demonstrated safety outcomes consistent with the known profile of adalimumab, and the treatment led to sustained reduction of clinical and endoscopic disease activity.

Project description:Abstract Background Oral octreotide capsules (OOC) are a treatment option for patients with acromegaly in the United States. The MPOWERED trial (NCT02685709) showed that OOC were noninferior to injectable somatostatin receptor ligands (iSRLs; octreotide or lanreotide) in maintenance of biochemical control in patients previously responding to both treatments, as well as demonstrated improvements in patient-reported outcomes among patients receiving OOC. Objective Report long-term safety and efficacy outcomes with OOC from the open-label extension (OLE) of MPOWERED. Methods Patients were eligible for and could voluntarily enroll into the OLE if they had completed the 15-month core treatment phase of MPOWERED (6-month Run-in phase plus 9-month randomized controlled treatment [RCT] phase or, for OOC nonresponders during/at end of Run-in at participating sites, combination sub-study evaluating OOC in combination with cabergoline) and were adequately biochemically controlled per investigator assessment. Maintenance of response (definition: IGF-I <1.3×ULN; single timepoint) was assessed in each year of the OLE in patients responding at the start of that year. Additional analyses were performed on patients switching to OOC in the OLE from iSRLs in the core study. Results Sixty patients elected to enroll in the OLE (35 who received OOC and 19 who received iSRLs in the RCT phase, 6 from the combination sub-study). Median and maximal OOC exposure durations in the OLE were 2.2 and 3.5 years, respectively. A total of 94%, 90%, and 93% of patients receiving OOC monotherapy maintained biochemical response at the end of years 1, 2, and 3 of the OLE, respectively (using last observation carried forward imputation). Of patients switching from iSRLs to OOC during the OLE, 79% reported very good (47%) or excellent (32%) symptom control at the end of the OLE, compared with 47% (42% very good, 5% excellent) at the end of the RCT phase while receiving iSRLs. Patients switching from iSRLs also experienced significant improvements in the treatment convenience and treatment satisfaction domains (both P<0.05) of the Acromegaly Treatment Satisfaction Questionnaire. Median OOC compliance rate during the OLE was 99%. OOC safety during the OLE was consistent with that observed during the core study, with no new safety signals observed with long-term exposure. Conclusions The OLE of MPOWERED demonstrated a high percentage (≥90%) of patients maintaining biochemical response while receiving OOC monotherapy with a favorable long-term safety profile of OOC. Those who switched from iSRLs to OOC demonstrated improvements in symptom control, treatment convenience, and treatment satisfaction.

Project description:BACKGROUND:Galcanezumab, a humanized monoclonal antibody that selectively binds to the calcitonin gene-related peptide, has demonstrated in previous Phase 2 and Phase 3 clinical studies (?6-month of treatment) a reduction in the number of migraine headache days and improved patients' functioning. This study evaluated the safety and tolerability, as well as the effectiveness of galcanezumab for up to 12 months of treatment in patients with migraine. METHODS:Patients diagnosed with episodic or chronic migraine, 18 to 65 years old, that were not exposed previously to galcanezumab, were randomized to receive galcanezumab 120 mg or 240 mg, administered subcutaneously once monthly for a year. Safety and tolerability were evaluated by frequency of treatment-emergent adverse events (TEAEs), serious adverse events (SAEs), and adverse events (AEs) leading to study discontinuation. Laboratory values, vital signs, electrocardiograms, and suicidality were also analyzed. Additionally, overall change from baseline in the number of monthly migraine headache days, functioning, and disability were assessed. RESULTS:One hundred thirty five patients were randomized to each galcanezumab dose group. The majority of patients were female (>?80%) and on average were 42 years old with 10.6 migraine headache days per month at baseline. 77.8% of the patients completed the open-label treatment phase, 3.7% of patients experienced an SAE, and 4.8% discontinued due to AEs. TEAEs with a frequency???10% of patients in either dose group were injection site pain, nasopharyngitis, upper respiratory tract infection, injection site reaction, back pain, and sinusitis. Laboratory values, vital signs, or electrocardiograms did not show anyclinically meaningful differences between galcanezumab dosesOverall mean reduction in monthly migraine headache days over 12 months for the galcanezumab dose groups were 5.6 (120 mg) and 6.5 (240 mg). Level of functioning was improved and headache-related disability was reduced in both dose groups. CONCLUSION:Twelve months of treatment with self-administered injections of galcanezumab was safe and associated with a reduction in the number of monthly migraine headache days. Safety and tolerability of the 2 galcanezumab dosing regimens were comparable. TRIAL REGISTRATION:ClinicalTrials.gov as NCT02614287 , posted November 15, 2015.

Project description:IntroductionCentral neuropathic pain (CNeP) is difficult to treat and has diverse etiology, including spinal cord injury (CNePSCI), Parkinson's disease (CNePPD), and central post-stroke pain (CPSP). The safety and efficacy of mirogabalin have been demonstrated in short-term trials, including patients with CNePSCI. The objective of our study was to confirm the safety/efficacy of mirogabalin in patients with CNePPD and CPSP, and obtain long-term data for CNePSCI.MethodsThis 52-week, open-label extension of a previous randomized controlled study was conducted across Japan, Korea, and Taiwan. Patients with CNePSCI, CNePPD, or CPSP received twice daily (BID) 5-10 mg mirogabalin for a 4-week titration period, after which the dosage was maintained for 47 weeks at a maximum of 15 mg BID, followed by a 1-week taper period receiving the same dose but only administered once daily. The primary endpoint was safety, assessed primarily by incidence and severity of treatment-emergent adverse events (TEAEs). Efficacy was assessed in a post hoc analysis of data obtained by the short-form McGill Pain Questionnaire (SF-MPQ).ResultsOf the 210 patients enrolled, 106, 94, and 10 had CNePSCI, CPSP, and CNePPD, respectively. The mean overall age of patients was 62.9 years, and most patients were male and of Japanese ethnicity. TEAEs occurred in 84.8% of patients, the most common being somnolence (16.7%), peripheral edema (12.4%), edema (11.4%), nasopharyngitis (11.0%), and dizziness (7.6%). Most TEAEs were mild. Severe and serious TEAEs occurred in 6.2% and 13.3% of patients, respectively. All patient groups experienced reductions in SF-MPQ visual analog scores for pain: mean ± standard deviation changes from baseline at week 52 were -2.3 ± 21.13 mm (CNePSCI), -17.0 ± 24.99 mm (CPSP), and -17.1 ± 35.32 mm (CNePPD).ConclusionMirogabalin was generally safe, well tolerated, and effective for treatment of CNeP in this long-term study.Trial registrationClinicalTrials.gov identifier, NCT03901352.

Project description:BackgroundChildren aged ≥ 6 to < 12 years with severe atopic dermatitis (AD) have limited treatment options. In a 16-week, randomized, placebo-controlled, phase III trial in children, dupilumab, a monoclonal antibody inhibiting interleukin (IL)-4/IL-13 signalling, significantly improved signs and symptoms with acceptable safety; longer-term safety and efficacy data are lacking.ObjectivesTo report the pharmacokinetic profile and long-term safety and efficacy of dupilumab in children (aged ≥ 6 to < 12 years) with severe AD.MethodsChildren (aged ≥ 6 to < 12 years) with severe AD were enrolled in a global, multicentre, phase IIa, open-label, ascending-dose, sequential cohort study and subsequent open-label extension (OLE) study. Patients received single-dose dupilumab 2 or 4 mg kg-1 followed by 8-week pharmacokinetic sampling, then 2 or 4 mg kg-1 weekly for 4 weeks (phase IIa), followed by the same weekly regimen (OLE). Primary endpoints were dupilumab concentration-time profile and treatment-emergent adverse events (TEAEs); secondary assessments included Eczema Area and Severity Index (EASI) and Peak Pruritus Numeric Rating Scale (PP-NRS) score.ResultsOf 38 children enrolled, 37 completed phase IIa and 33 continued to the OLE. Nonlinear, target-mediated pharmacokinetics characterized dupilumab concentrations (week 24-48 mean serum concentrations: 2 mg kg-1 , 61-77 mg L-1 ; 4 mg kg-1 , 143-181 mg L-1 ). TEAEs were mostly mild to moderate and transient; none led to treatment discontinuation. The most commonly reported TEAEs were nasopharyngitis (2 mg kg-1 , 47%; 4 mg kg-1 , 56%) and AD exacerbation (29% and 13%, respectively). Single-dose dupilumab rapidly improved AD with further improvements through week 52. Mean EASI and PP-NRS improved by -37%/-33% and -17%/-20% at week 2 (phase IIa) and -92%/-84% and -70%/-58% at week 52 (OLE), respectively.ConclusionsThese safety and efficacy results support the use of dupilumab as a continuous long-term treatment for children aged ≥ 6 to < 12 years with severe AD.

Project description:ObjectiveTo assess long-term (up to 2 years) efficacy, tolerability, and safety of erenumab for the prevention of episodic migraine (EM) in Japanese patients.BackgroundPreviously published results from the double-blind treatment phase (DBTP) of a phase 2 clinical study have demonstrated the efficacy and safety of erenumab in Japanese patients with EM.MethodsPatients completing the 24-week placebo-controlled DBTP could continue into the 76-week open-label treatment phase (OLTP), receiving erenumab 70 mg or 140 mg subcutaneously once monthly. The initial dose in the OLTP was erenumab 70 mg monthly, which was later changed to 140 mg. After study completion, the following were assessed: change from baseline in monthly migraine days (MMD), change from baseline in monthly acute migraine-specific medication days (MSMD), percentage of patients achieving ≥50% and ≥75% reduction in MMD, change from baseline in the 6-item Headache Impact Test (HIT-6™) score, and safety (exposure-adjusted patient-incidence of adverse events [AEs], calculated as number of patients per 100 patient-years).ResultsOf 475 patients enrolled in the DBTP, 459 (96.6%) continued in the OLTP. The mean (SD) MMD was 7.9 (2.3) at baseline with the overall change from baseline at week 100 of -2.9 (4.1) days. The monthly acute MSMD was 5.7 (2.8) at baseline with change from baseline at week 100 of -1.7 (3.7) days. The proportion of patients who achieved ≥50% and ≥75% reduction in MMD from baseline at week 100 was 177/398 (44.5%) and 94/398 (23.6%), respectively. The HIT-6™ score was 58.4 (5.4) at baseline with a change of -6.4 (8.2) at week 100. The exposure-adjusted patient-incidence of AEs during the OLTP was 207.1/100 patient-years for the combined erenumab group, similar to that observed for either erenumab (271.0/100 patient-years) or placebo (257.3/100 patient-years) during the DBTP, and no new safety signals were detected during the OLTP.ConclusionLong-term erenumab treatment in Japanese patients with EM demonstrated sustained efficacy for up to 2 years, with a safety profile similar to previous studies, supporting erenumab as a potential new therapy for EM prevention in Japan.
