International, Multicentre, Parallel-group, Randomised, Double-blind, Placebo-controlled, Phase III Study Evaluating the effect of Dapagliflozin on Exercise Capacity in Heart Failure Patients with Preserved Ejection Fraction (HFpEF)
The study will evaluate the efficacy, safety, and tolerability of 450 milligrams (mg) of Rapastinel, compared to 10 mg of Vortixetine and placebo in participants with major depressive disorder (MDD).
The purpose of this study is to evaluate the efficacy of treating participants with treatment-resistant depression (TRD) who have failed at least 2 (and no more than 6) prior antidepressant (AD) treatments in the current moderate to severe depressive episode with flexibly-dosed esketamine nasal spray plus a newly initiated oral standard-of-care AD compared with placebo nasal spray plus a newly-initiated standard-of-care oral AD, in achieving remission and staying relapse-free after remission.
This is a Phase 2 multicenter, double-blind, placebo-controlled, randomized, parallel-group trial to assess the efficacy and safety of 2 once-daily oral doses of IMU-838 (vidofludimus calcium), a small molecule inhibitor of dihydroorotate dehydrogenase (DHODH), 30 mg/day and 45 mg/day, in patients with RRMS and evidence of active disease. The trial consists of a screening period, a blinded 24-week main treatment period, and an optional initially blinded, then open-label extended treatment period of up to 9.5 years. About 40 centers are planned to participate in Romania, Bulgaria, Ukraine, and Poland; potential additional centers in Hungary and Croatia. In total, 195 patients are planned to be randomized 1:1:1 to treatment with 30 mg/day or 45 mg/day IMU-838, or placebo (65 patients each) in the main treatment period. During the extended treatment period, patients will be re-randomized such that patients previously on placebo will be re-randomized 1:1 to treatment with 30 g/day or 45 mg/day IMU-838, all other patients will be re-randomized to the same treatment they previously received.
This study will evaluate the efficacy, safety, durability, and pharmacokinetics of faricimab administered at intervals as specified in the protocol, compared with aflibercept once every 8 weeks (Q8W), in participants with neovascular age-related macular degeneration (nAMD).
