Testing the Addition of Anti-Cancer Drug, Cetuximab, to Standard of Care Treatment (Pembrolizumab) for Returning or Spreading Head and Neck Cancer After Previous Treatment
NCT06589804
Recruiting
This phase III trial compares the effect of adding cetuximab to pembrolizumab versus pembrolizumab alone in treating patients with head and neck squamous cell carcinoma (HNSCC) that has come back after a period of improvement (recurrent) and/or that has spread from where it first started (primary site) to other places in the body (metastatic). Cetuximab is in a class of medications called monoclonal antibodies. It binds to a protein called EGFR, which is found on some types of tumor cells. This... Read More

Sequential Therapy in Multiple Myeloma Guided by MRD Assessments
NCT05231629
Recruiting
This research study will determine the proportion of patients with lowest minimal residual disease (MRD) response obtainable after receiving 6 cycles of study treatment. Minimal residual disease is multiple myeloma cells below the level of 1 cancer cell out of 100,000 in the bone marrow. For patients who become MRD "negative" (i.e. less than 1 cancer cell out of 100,000) at the end of 6 cycles of therapy, this study will study if that good response can be maintained with 3 additional cycles of...

A Phase 2 Study of NEU-411 in Companion Diagnostic-Positive Participants With Early Parkinson's Disease
NCT06680830
Recruiting
The goal of this Phase 2 clinical trial is to investigate the efficacy and safety of NEU-411 in men and women aged 40-80 years with early Parkinson's Disease (PD) who have predicted elevations in the activity of the "leucine-rich repeat kinase 2" ("LRRK2" for short) pathway based on their genetic profile. A DNA test will be used to identify the "LRRK2-driven" population with predicted elevation in the LRRK2 pathway. Participants will: • Take NEU-411 or placebo every day for 52 weeks
