Researchers are evaluating the pharmacokinetic comparability between TAK-881 and HYQVIA when given as subcutaneous injections for maintenance therapy in adults with chronic inflammatory demyelinating polyradiculoneuropathy CIDP. This phase 3 trial focuses on participants who have been receiving intravenous or subcutaneous immunoglobulin treatments and aims to compare these two treatments in terms of how the body absorbs and processes them. The study includes several phases starting with screening and possibly a ramp-up phase for those switching treatments. Participants already on HYQVIA go directly to that treatment phase, which lasts 18 to 20 weeks depending on dosing intervals. Then all participants switch to TAK-881 for 24 weeks. After this, an extension phase allows continued treatment for up to 3 years, with home infusions permitted and clinic visits spaced between 12 and 24 weeks. Treatments are given by subcutaneous infusion using specialized needle sets. Participants will visit the clinic every 3 or 4 weeks during the initial phases to undergo assessments including blood sampling to measure immunoglobulin G levels at various time points. The study also tracks clinical disability scores, hand grip strength, muscle strength, and adverse events over time. Safety and treatment tolerability are closely monitored throughout the trial. Total participation may last several years including the extension phase.

Researchers are evaluating the efficacy, safety, and tolerability of remibrutinib compared to a placebo in adult patients with Generalized Myasthenia Gravis gMG who are already on stable standard-of-care treatments. This multicenter Phase III study is randomized, double-blind, and placebo-controlled, aiming to provide important information about remibrutinibs impact on gMG symptoms. Participants will be randomly assigned to one of two groups one receiving remibrutinib tablets orally, and the other receiving matching placebo tablets, both during a 6-month core treatment period. Following this, participants can join an extension phase lasting up to 60 months, where all will receive open-label remibrutinib tablets orally. During the study, participants will undergo various assessments to monitor their symptoms and quality of life, including the Myasthenia Gravis Activity of Daily Living MG-ADL score and other clinical scales. Safety and tolerability will also be closely observed throughout the core and extension periods. The total duration of participation may extend up to nearly six years, including both study phases.

Researchers are studying the effectiveness of riliprubart compared to intravenous immunoglobulin IVIg in adults with Chronic Inflammatory Demyelinating Polyneuropathy CIDP who are already receiving IVIg maintenance treatment. This Phase 3 trial aims to evaluate how well riliprubart works and its safety over a study period lasting up to 109 weeks, including screening, treatment, and follow-up phases. Participants are randomly assigned to one of two groups one receives riliprubart along with a placebo IVIg infusion for 24 weeks, followed by a 24-week open-label extension phase where all receive riliprubart the other group continues IVIg treatment with a placebo riliprubart for 24 weeks, then also enters the open-label extension phase receiving riliprubart. The study uses intravenous and subcutaneous solutions for administration and includes a double-blind design to compare treatments fairly. During the study, participants undergo various assessments including disability scales, grip strength measurements, fatigue scales, and health quality evaluations from baseline up to week 48 and beyond. Researchers will monitor treatment responses, relapses, adverse events, and immune responses throughout the trial. Participants are followed closely for safety and effectiveness until the study concludes, with total involvement lasting up to 109 weeks.
