Researchers are evaluating the Galleri4 multi-cancer early detection (MCED) test in a multi-center prospective cohort study involving the Medicare population aged 50 years and older. This study aims to understand the real-world clinical impact of the test, including its safety and how well it detects cancers early. The study seeks to enroll participants who represent the Medicare population, including those with Traditional Medicare or Medicare Advantage coverage. Participants in the study are divided into two groups: one group receives the Galleri test through blood collection and multi-cancer early detection testing with return of results, while the other group receives usual care without the Galleri test. The study excludes individuals who have previously had an MCED test, are undergoing clinical evaluation for suspected cancer, have certain recent or untreated cancer histories, are pregnant, or are currently inpatient at a participating site. The study is designed to monitor participants over time without specifying a maximum age limit. During the study, researchers will track the incidence rates of stage IV cancers over a period of up to 3 years. Participants will be monitored for safety and test performance outcomes. The study involves informed consent from participants who are capable of providing it directly, and it excludes those who cannot comply with study procedures or who are not registered patients at participating centers. This research aims to provide data on the effectiveness and safety of the Galleri test in a real-world Medicare population setting.

Researchers are evaluating the effectiveness of radiation therapy combined with chemotherapy and immunotherapy in patients with high-risk stage III-IV squamous cell carcinoma of the head and neck that is HPV-negative. The study aims to compare the usual treatment of radiation therapy with cisplatin chemotherapy against two experimental approaches: radiation with docetaxel and cetuximab chemotherapy, and the usual treatment plus the immunotherapy drug atezolizumab. This phase II/III trial focuses on improving disease-free and overall survival in this patient population. Participants are randomly assigned to one of three treatment groups. One group receives intensity-modulated radiation therapy (IMRT) with weekly cisplatin for 6 weeks. Another group receives IMRT with weekly docetaxel and cetuximab. The third group receives IMRT with weekly cisplatin plus atezolizumab administered intravenously every 3 weeks starting one week before radiation, for up to eight doses. Treatments are given in the absence of disease progression or unacceptable side effects. Throughout the study, patients undergo blood sample collection and may have CT scans, MRI, and biopsies as needed. Follow-up visits occur at 1 and 3 months post-treatment, then every 3 months for 2 years, every 6 months for 3 years, and annually thereafter. Researchers measure disease-free survival up to 7 years, overall survival up to 7 years, symptom burden, quality of life, and treatment-related toxicities. Blood and tissue specimens are collected for future research.
