The purpose of this study was to provide 16-week efficacy, safety and tolerability data versus placebo to support the use of secukinumab 150 mg by subcutaneous (s.c.) self-administration with or without a loading regimen and maintenance dosing using pre-filled syringe (PFS) and to assess efficacy, safety and tolerability up to 2 years in subjects with active PsA despite current or previous NSAID or DMARD therapy
The purpose of this study is to determine whether ozanimod is effective in the treatment of relapsing multiple sclerosis (RMS).
This is a randomized, double-blind, placebo-controlled study that will investigate the safety and clinical activity of a single intravenous (IV) dose of MHAA4549A in adult participants hospitalized with severe influenza A in combination with oseltamivir versus a comparator arm of placebo with oseltamivir.
The purpose of this study is to estimate the risk of bleeding with rivaroxaban, compared with acetylsalicylic acid (ASA), in addition to a single antiplatelet/ platelet adenosine diphosphate P2Y12 receptor antagonist (P2Y12 inhibitor agent: clopidogrel or ticagrelor), in participants with a recent acute coronary syndrome (ACS: including ST segment elevation myocardial infarction [STEMI] and non-ST-segment elevation acute coronary syndrome [NSTE-ACS]).
The purpose of this open-label, single arm, multi-center Expanded Treatment Protocol (ETP) was to provide early access to ruxolitinib and evaluate safety information in patients with polycythemia vera (PV) who were hydroxyurea (HU) resistant or intolerant and who had no other standard treatment option, nor did they qualify for another clinical study for PV
The purpose of the study is to evaluate the clinical efficacy, safety and tolerability of apremilast (30 mg twice daily [BID] and 40 mg BID), compared with placebo, in participants with active Ulcerative Colitis (UC).
The primary objective of this study is: - To assess the efficacy and safety of dose regimens of ALX-0061 monotherapy administered subcutaneously (s.c.) to subjects with active rheumatoid arthritis (RA). The secondary objectives of this study are: - To assess the effects of ALX-0061 on quality of life, the pharmacokinetics (PK), pharmacodynamics (PD), and immunogenicity of ALX-0061 and to explore potential dose regimens for ALX-0061 monotherapy, based on safety and efficacy, for further clinical development. - To obtain parallel descriptive information concerning the efficacy and safety of tocilizumab (TCZ) s.c. in the same clinical trial RA population.
The main objectives of Part 1 are as follows: To evaluate the safety, tolerability, and efficacy of BG00012 in pediatric subjects with RRMS, as compared with a disease-modifying treatment and to assess health outcomes and evolution of disability.
