Researchers are evaluating the efficacy of claseprubart (DNTH103) compared to placebo in adults with chronic inflammatory demyelinating polyneuropathy (CIDP) in this Phase 3 study. The goal is to assess how well claseprubart works in treating this condition, which involves nerve inflammation leading to muscle weakness and sensory problems. The study consists of multiple periods: Part A is an open-label phase lasting up to 13 weeks where all participants receive claseprubart. Those who respond move to Part B, a randomized, double-blind, placebo-controlled phase lasting up to 52 weeks, where participants receive either claseprubart or placebo by infusion or injection. After Part B, eligible participants may join an optional open-label extension for up to 104 weeks. A safety follow-up period of 40 weeks follows the treatment phases. Participants will undergo various assessments including neurological evaluations and disease activity scoring. Researchers will monitor the time from the first dose to disease relapse as the main outcome. Additional safety and efficacy measures will be tracked throughout all study periods. Total participation may last over two years including extension and follow-up phases.

Researchers are evaluating surgical and minimally invasive treatments for lumbar spinal stenosis (LSS) by comparing Medicare patients who received the MILD procedure against those who had interspinous process decompression (IPD). The study focuses on outcomes such as the rate of harms related to the initial procedure and the frequency of additional surgical or minimally invasive interventions within 24 months after treatment. Enrollment includes patients treated from January 1, 2017, onward, with continuation until the sponsor decides to stop. The MILD procedure involves percutaneous image-guided lumbar decompression, performed under fluoroscopy through a dorsal approach to partially remove tissue and bone at the affected spinal level. The control group receives the IPD procedure for LSS. Both groups are monitored for a 24-month period post-index procedure using Medicare claims data to track reoperations and any harms. Participants contribute data through Medicare claims without needing prior enrollment or consent, as the study is exempt from IRB oversight. Researchers collect and analyze information on procedure-related harms and subsequent interventions over two years. This approach allows evaluation of long-term safety and effectiveness outcomes for patients treated with either MILD or IPD.
