Researchers are evaluating zanidatamab for treating adults with previously treated solid tumors that overexpress the HER2 protein at a high level IHC 3. This Phase 2 study focuses on participants whose tumors have progressed after at least one prior systemic treatment and who have no other confirmed beneficial treatment options. The study excludes certain cancers like biliary tract cancer and considers prior HER2 therapy differently across tumor cohorts. Participants receive zanidatamab through intravenous infusion. The study includes a single treatment group with no placebo comparison. Treatment continues as per protocol with monitoring for responses and safety. The study collects tumor samples centrally to confirm HER2 status and requires measurable disease for evaluation. Various cohorts have specific prior treatment requirements. During the study, participants undergo assessments including tumor response evaluation by independent review and investigators using standard criteria RECIST 1.1. The trial monitors treatment safety, side effects, drug levels in the blood, and immune reactions to the drug. Participants will be followed for up to 2.5 years for response and safety, and overall survival is tracked for up to 3.5 years, with regular visits to assess health status and treatment effects.

Researchers are evaluating petosemtamab compared with investigators choice monotherapy in patients with incurable metastatic or recurrent head and neck squamous cell carcinoma HNSCC who have previously been treated. This phase 3 open-label, randomized controlled study focuses on patients whose disease has progressed after anti-PD-1 and platinum-containing therapies. It aims to assess effectiveness and safety for second- and third-line treatments in this population. Participants will be randomly assigned to receive either petosemtamab or one of several investigators choice monotherapies, including cetuximab, methotrexate, or docetaxel. The treatments are given as part of a controlled multicenter trial. The study includes follow-up periods to evaluate responses and safety outcomes over time. During the study, participants will undergo regular assessments including radiologic evaluations to measure tumor response according to RECIST criteria, physical performance status checks, and laboratory tests to monitor organ function and adverse events. Researchers will track overall survival for up to approximately three years and evaluate other outcomes such as progression-free survival, response rates, quality of life measures, and treatment safety. The total duration of participation is aligned with treatment and outcome measurement timelines as specified.

Researchers are evaluating treatments for participants with KRASNRAS and BRAF wild-type recurrent, unresectable, or metastatic colorectal cancer who have previously received chemotherapy. The study compares how long participants remain free of disease progression and the overall survival time when treated with amivantamab plus chemotherapy versus cetuximab or bevacizumab plus chemotherapy. This Phase 3 trial focuses on patients who have already undergone prior chemotherapy for their cancer. Participants are randomly assigned to one of two groups. One group receives amivantamab combined with the chemotherapy regimen FOLFIRI, which includes 5-fluorouracil, leucovorin calcium or levoleucovorin, and irinotecan. The other group receives either cetuximab or bevacizumab combined with the same chemotherapy regimen FOLFIRI. Treatments are given in 28-day cycles and continue until the cancer progresses or other criteria require stopping treatment. During the study, participants undergo regular assessments to monitor disease status, including imaging scans reviewed by independent experts. Researchers measure progression-free survival and overall survival over periods up to several years. Additional outcomes include response rates, duration of response, quality of life assessments, and side effects. Safety and laboratory evaluations are conducted throughout the study, which spans up to four years and four months in total duration.

Researchers are evaluating nemtabrutinib compared with investigators choice of ibrutinib or acalabrutinib in adults with untreated chronic lymphocytic leukemia CLL or small lymphocytic lymphoma SLL. The study aims to assess whether nemtabrutinib is not worse than these comparators in terms of objective response rate and whether it can provide longer progression-free survival. This is a Phase 3 randomized clinical trial sponsored by Merck Sharp & Dohme LLC. Participants will receive either nemtabrutinib, ibrutinib, or acalabrutinib orally at specified doses until their disease progresses, unacceptable side effects occur, or other discontinuation criteria are met. The trial uses a parallel-group design where participants are randomly assigned to one of the treatment groups, and no masking is involved. Both treatment arms continue until progression or intolerance. During the study, participants will be monitored regularly up to about 33 months for response rate and up to about 104 months for progression-free survival and overall survival. Assessments include clinical evaluations, safety monitoring for adverse events, and duration of response measurements. The study tracks treatment tolerability, discontinuations due to adverse events, and overall outcomes to better understand the therapies effects in this patient population.

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.
