Researchers are conducting a phase 3 open-label, randomized, controlled, multicenter study to compare petosemtamab with investigator's choice monotherapy in patients with head and neck squamous cell carcinoma (HNSCC) who have incurable metastatic or recurrent disease. This study focuses on patients with progressive disease after anti-PD-1 therapy and platinum-containing therapy and aims to evaluate the treatments as second- or third-line options. Participants will receive either petosemtamab or one of the investigator's choice monotherapies, including cetuximab, methotrexate, or docetaxel. The study involves treatment administration under controlled conditions with monitoring for efficacy and safety. The goal is to assess the treatments over time with a focus on response rates and overall survival. During the study, participants will undergo regular assessments including radiologic imaging to measure tumor response, and evaluations of overall survival up to approximately three years. The primary outcomes include objective response rate assessed by blinded independent central review and overall survival. Researchers will monitor patient health, side effects, and treatment effectiveness throughout the study duration.

Researchers are evaluating the safety and effectiveness of combining petosemtamab with pembrolizumab compared to pembrolizumab alone as a first treatment for people with recurrent or metastatic PD-L1 positive head and neck squamous cell carcinoma (HNSCC). This Phase 3, randomized, open-label study focuses on patients who have not received previous systemic therapy for incurable recurrent or metastatic disease, though prior therapy for locally advanced disease is allowed under certain conditions. The study excludes patients who have been treated with anti PD-(L)1 or anti-EGFR therapies except in specific cases. Participants will receive either the combination of petosemtamab plus pembrolizumab or pembrolizumab alone as their first-line treatment for this condition. The study includes detailed eligibility criteria based on tumor location, PD-L1 expression, health status, and prior treatments. Treatment effects will be observed over time with a focus on overall survival and tumor response rates measured according to standard criteria. During the study, participants will undergo assessments including tumor biopsies, imaging scans to measure disease progression, heart function tests, and evaluations of organ function. Safety and treatment response will be closely monitored up to approximately three years. The study also tracks overall survival and tumor response rate as primary outcomes, ensuring continuous follow-up and support throughout the trial period.

Researchers are evaluating treatments for newly diagnosed ANCA-associated vasculitis, a serious disease involving inflammation of small to medium blood vessels. This phase 4 trial compares whether avacopan combined with short-term reduced-dose glucocorticoids and rituximab works as well as a longer 20-week reduced-dose glucocorticoid and rituximab treatment for achieving remission. The study also examines if avacopan lowers relapse rates compared to rituximab maintenance therapy and assesses the long-term safety of avacopan. Participants will be randomly assigned to one of two treatment groups. One group receives avacopan with short-term (up to 4 weeks) reduced-dose prednisolone and rituximab given at the start. The other group receives reduced-dose prednisolone for up to 20 weeks combined with rituximab administered at weeks 0, 26, 52, and 78. The study is open-label and will follow patients for up to 104 weeks to compare remission, relapse, and safety outcomes. Patients will be evaluated at multiple time points from baseline through week 104. Assessments include disease status (remission or relapse), disease activity scores, damage indexes, and adverse events. The main outcome is the proportion of patients achieving remission at 26 weeks. Researchers will monitor long-term safety and relapse rates over two years to better understand the benefits and risks of these treatment approaches.
