Efficacy and safety of ipragliflozin as add-on therapy to insulin in Japanese patients with type 2 diabetes mellitus (IOLITE): a 36-week, open-label extension of a 16-week, randomized, placebo-controlled, double-blind study.

ABSTRACT:

Objective

To examine long-term efficacy/safety of ipragliflozin, a sodium-glucose cotransporter 2 inhibitor, added to ongoing insulin therapy in Japanese patients with type 2 diabetes.

Methods

We conducted a 36-week, open-label extension of ipragliflozin therapy following a 16-week, randomized, placebo-controlled, double-blind period (treatment periods II and I, respectively). Prior to the open-label period, patients taking insulin with/without a dipeptidyl peptidase-4 (DPP-4) inhibitor were randomized to receive placebo or 50 mg once-daily ipragliflozin. Oral antidiabetic drugs other than DPP-4 inhibitors were discontinued 4 weeks before screening. Following treatment period I, all patients received open-label ipragliflozin 50 mg, with the possibility of a dose increase to 100 mg at week 24 if HbA1c was ≥ 7.0% at week 20. Efficacy endpoints were changes in HbA1c, fasting plasma glucose (FPG), self-monitored blood glucose, bodyweight, and metabolic hormones. Drug-related treatment-emergent adverse events (TEAEs) were monitored for safety.

Results

Of 175 patients randomized to ipragliflozin, 168 entered treatment period II, 121 (69%) of whom completed this period. The mean ± standard deviation changes in HbA1c, FPG, and bodyweight from baseline (start of treatment period I) to the end of treatment were - 0.83 ± 0.72%, - 31.5 ± 41.2 mg/dL, and - 1.34 ± 1.80 kg, respectively. Between weeks 8 and 32, HbA1c was lower in patients taking a DPP-4 inhibitor than in those without. The most common drug-related TEAE was hypoglycemia; no drug-related TEAEs not already reported for ipragliflozin were observed.

Conclusions

Ipragliflozin was well tolerated, effective, and reduced bodyweight over a period of 52 weeks in patients treated with insulin with/without a DPP-4 inhibitor.

Project description:IntroductionFew data are available regarding ipragliflozin treatment in combination with glucagon-like peptide-1 (GLP-1) receptor agonists. The aim of this study was to evaluate the efficacy and safety of ipragliflozin in combination with GLP-1 receptor agonists in Japanese patients with inadequately controlled type 2 diabetes mellitus (T2DM).MethodsThis multicenter study (consisting of three periods: a 4-week washout period, a 6-week observation period, and a 52-week open-label treatment period) included patients aged ≥ 20 years who received a stable dose/regimen of a GLP-1 receptor agonist either solely or in combination therapy with a sulfonylurea for ≥ 6 weeks, with glycosylated hemoglobin (HbA1c) of ≥ 7.5% and a fasting plasma glucose (FPG) of ≥ 126 mg/dL. Ipragliflozin treatment was given at a fixed dose of 50 mg/day for 20 weeks, followed by 50 or 100 mg/day for 32 weeks. Changes from baseline in glycemic control and other parameters were examined; safety was also assessed.ResultsThe mean changes in HbA1c and body weight from baseline to end of treatment were - 0.92% and - 2.69 kg, respectively, in all ipragliflozin-treated patients (n = 103). Overall, sustained reductions from baseline were observed for HbA1c, FPG, self-monitored blood glucose, and body weight during the 52-week treatment. The dose increase of ipragliflozin to 100 mg/day resulted in better glycemic control and weight reduction for patients in whom the 50-mg dose was insufficient. Overall, 46.6% (48/103) of patients experienced drug-related adverse events. The most common drug-related treatment-emergent adverse events were pollakiuria (9.7%), hypoglycemia (8.7%), constipation (6.8%), and thirst (5.8%).ConclusionCombined therapy with ipragliflozin and GLP-1 receptor agonists/sulfonylureas was significantly efficacious in reducing glycemic parameters in patients with T2DM with inadequate glycemic control, and no major safety concerns were identified. The results from this study suggest that ipragliflozin can be recommended as a well-tolerated and effective add-on therapy to a GLP-1 receptor agonist for the treatment of T2DM.Trial registrationClinicalTrials.gov (identifier: NCT02291874).FundingAstellas Pharma Inc., Tokyo, Japan.

Project description:IntroductionThe long-term safety of dimethyl fumarate (DMF) in patients with relapsing-remitting multiple sclerosis (RRMS) has been studied in mainly Caucasian patients. The present interim analysis aimed to evaluate the 72-week safety of DMF in Japanese patients with RRMS.MethodsSafety data of Japanese subjects enrolled in the 24-week randomised, double-blind, placebo-controlled APEX study (Part I) and its following open-label extension (Part II) were analysed at 72 weeks from the beginning of Part I. In Part I, subjects were randomised to DMF treatment or matching placebo while all subjects received DMF treatment during Part II. Adverse events (AEs) reported throughout the study period were recorded.ResultsOverall, 109 Japanese subjects completed 72 weeks of treatment. The incidence of AEs and serious AEs was 95% and 19%, respectively, in the DMF group compared with 84% and 18%, respectively, in the placebo group at 24 weeks. Common AEs (at least 5%) reported with treatment included nasopharyngitis, flushing, hot flush, gastrointestinal events, pruritus, rash, headache, increased alanine aminotransferase (ALT) and aspartate aminotransferase (AST). AEs led to discontinuation of DMF in 5% of patients and included MS relapse, flushing, abdominal pain, liver disorder and increased ALT/AST. After an initial decrease from baseline of 17% in the DMF group at week 24, the mean lymphocyte counts stabilised and were maintained until week 72. No opportunistic/serious infections nor malignancies were reported with DMF treatment. The incidences of AEs, serious AEs, and discontinuation due to AEs were similar between the DMF and the placebo groups.ConclusionThe 72-week safety profile of DMF in Japanese patients with RRMS was consistent with previous studies that enrolled mostly Caucasian patients, with a lower incidence of flushing and related symptoms and a lower reduction in the lymphocyte count compared with previous reports.Trial registrationClinicalTrials.gov identifier NCT01838668.FundingBiogen Japan Ltd.

Project description:ObjectivesThe long-term safety, tolerability, and efficacy of paliperidone extended-release (ER) were evaluated in Chinese patients with schizophrenia.MethodsPatients (aged ≥18 years) with schizophrenia (Diagnostic and Statistical Manual of Mental Disorders, 4th edition criteria) who had completed run-in (8-week), stabilization (6-week), and double-blind (DB) phases (variable) of a phase-3, placebo-controlled study entered this 24-week, open-label extension (OLE) study. These patients, who had either experienced a relapse or remained relapse-free through DB phase of the study, were treated with flexible-dose paliperidone-ER (3-12 mg/day) during the OLE phase. Major safety evaluations included treatment-emergent adverse events (TEAEs) and extrapyramidal symptoms. Efficacy endpoints included changes in Positive and Negative Syndrome Scale total score, Clinical Global Impression-Severity scale, and Personal and Social Performance scale from OLE baseline to OLE endpoint.ResultsOut of 106 patients who entered the OLE phase (placebo: 59, paliperidone-ER: 47), a total of 85 (80%) completed it. Thirty-five (33%) patients experienced at least one TEAE; most common were akathisia, somnolence, nasopharyngitis, and constipation (3.8% each). Serious TEAEs were noted in two patients (completed suicide; schizophrenia worsening). No TEAEs with an onset during the OLE phase led to discontinuation. Extrapyramidal symptoms related-TEAEs were reported in eight (7.5%) patients. Mean (standard deviation) changes in Positive and Negative Syndrome Scale total scores (-10.4 [13.2]), Clinical Global Impression-Severity scores (-0.6 [0.96]) and Personal and Social Performance scores (7.4 [13.2]) from OLE baseline to OLE endpoint showed patients who had been treated with placebo during the DB phase experienced more pronounced improvements.ConclusionIn this OLE study, flexibly dosed paliperidone-ER (3-12 mg/day) was tolerable and efficacious in Chinese patients with schizophrenia.

Project description:ObjectiveThe purpose of this study was to evaluate the safety and efficacy of asenapine in adolescents with schizophrenia.MethodsIn an 8 week, randomized, double-blind placebo-controlled trial, subjects (12-17 years of age) meeting Diagnostic and Statistical Manual of Mental Disorders, 4th ed., Text Revision (DSM-IV-TR) criteria for schizophrenia were randomized 1:1:1 to placebo, asenapine 2.5 mg b.i.d., or asenapine 5 mg b.i.d. Subjects who completed the 8 week acute study could participate in a 26 week flexible-dose asenapine-only open-label extension (OLE).ResultsA similar percentage of subjects completed treatment on day 56 (2.5 mg b.i.d. (n=98): 83%; 5 mg b.i.d. [n=106]: 79%; placebo [n=102]: 79%). In the mixed model for repeated measures analysis of the primary end-point (with Hochberg correction for multiplicity), least squares (LS) mean differences between asenapine and placebo on the Positive and Negative Syndrome Scale (PANSS) total score at day 56 were not significant (-4.8 for 2.5 mg b.i.d., p=0.070; -5.6 for 5 mg b.i.d., p=0.064). Significant improvement in the Clinical Global Impressions-Severity score was observed in the 5 mg b.i.d. group versus placebo on day 56 (LS mean -0.3, p=0.024). In the acute phase, ≥7% weight gain and the composite event of somnolence, sedation, and hypersomnia were more common in both asenapine groups than in the placebo group. Akathisia, fasting glucose elevation, and extrapyramidal syndrome were more common in the 5 mg b.i.d. group than in the placebo group. There were no unexpected adverse events in the OLE, and PANSS total scores decreased by -16.1 points in the group previously treated with placebo (n=62) and by -11.2 points in the continuous asenapine group (n=131) from OLE baseline to week 26.ConclusionsAlthough improvements in PANSS total score at day 56 of the acute phase were numerically greater for both asenapine 2.5 and 5 mg b.i.d. than for placebo and were maintained in the OLE, the primary end-point did not achieve statistical significance in the acute phase. No new or unexpected safety concerns were detected during the acute phase or after an additional 26 weeks of asenapine treatment in the adolescent population with schizophrenia.Clinical trials registryNCT01190254 and NCT1190267 at ClinicalTrials.gov.
