Researchers are evaluating the effectiveness of claseprubart DNTH103 compared to a placebo in adults with chronic inflammatory demyelinating polyneuropathy CIDP. This Phase 3 study aims to assess treatment outcomes in participants with typical CIDP or certain CIDP variants, focusing on improving disease activity and disability measures. The study consists of several periods Part A includes an open-label phase lasting up to 13 weeks where participants receive an intravenous loading dose of claseprubart followed by subcutaneous injections every two weeks. Part B is a randomized, placebo-controlled, double-blind treatment phase lasting up to 52 weeks for those who respond to treatment in Part A, with participants receiving either claseprubart or placebo subcutaneously every two weeks. Eligible participants may then join an optional open-label extension lasting up to 104 weeks, continuing claseprubart treatment subcutaneously every two weeks, followed by a safety follow-up period of 40 weeks. Participants will undergo regular assessments throughout the study, including evaluations of disease relapse using the Adjusted Inflammatory Neuropathy Cause and Treatment INCAT score, disability scales, grip strength measurements, quality of life, fatigue severity, and antibody levels. Safety monitoring involves tracking adverse events and drug serum concentrations. The total study duration can extend up to approximately 209 weeks, including all treatment and follow-up phases, with careful monitoring of participants neurological stability and treatment responses.

Researchers are comparing the rates of surgical and minimally invasive interventions, as well as any harms, in Medicare beneficiaries treated with the MILD procedure versus those treated with interspinous process decompression IPD for lumbar spinal stenosis with neurogenic claudication. This observational study uses Medicare claims data to follow patients for 24 months after their initial procedure starting from January 1, 2017. The purpose is to evaluate outcomes between these two types of procedures without requiring prior patient enrollment or consent. The study includes two groups patients who received MILD, which is a percutaneous image-guided lumbar decompression performed under fluoroscopic guidance through a dorsal approach to the spine, and patients who received IPD, a different device-based decompression procedure. Data on reoperations and complications will be collected for both groups over a 24-month follow-up period using Medicare claims. Enrollment continues until the sponsor decides to stop. Participants involvement is passive as the study uses existing Medicare claims data. Researchers will monitor rates of harms related to the initial procedure and subsequent surgical or minimally invasive interventions over two years. No direct patient visits or interventions are conducted, and the study is exempt from institutional review board oversight. The total study duration extends to December 2026, covering cases treated since early 2017.
