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.

Researchers are evaluating whether a new medicine called PF-08634404, given with chemotherapy, works better than the current standard treatment of pembrolizumab combined with chemotherapy for adults with a type of lung cancer known as non-small cell lung cancer NSCLC. This study focuses on participants with locally advanced or metastatic NSCLC who are not candidates for surgery or curative chemoradiotherapy and have no known actionable genomic alterations. The study is a Phase 3 randomized trial with double-blind masking to compare these treatments. Participants are assigned to one of two parts based on their tumor type those with squamous NSCLC are in Part 1, and those with non-squamous NSCLC are in Part 2. Each participant is randomly placed into one of two treatment groups the experimental group receives PF-08634404 plus chemotherapy, while the control group receives pembrolizumab plus chemotherapy. Treatments are given through intravenous infusions in cycles, followed by maintenance therapy with either PF-08634404 or pembrolizumab, depending on the part of the study. Participants continue treatment as long as it helps and side effects are manageable. During the study, participants attend regular visits for treatment and health assessments. Cancer response is checked every 6 weeks for the first 48 weeks and then every 12 weeks after that. Researchers monitor overall survival, progression-free survival, objective response rates, duration of response, adverse events, lab abnormalities, and quality of life measures. The study includes detailed tracking of drug levels and immune responses. Participation may last up to approximately 39 months, with continuous safety and effectiveness monitoring.
