A Study of Zasocitinib in Adults With Psoriatic Arthritis Who Have or Have Not Been Treated With Biologic Medicines
Recruiting
Psoriatic arthritis (PsA) is a chronic inflammatory disease that affects the joints and skin in people who have psoriasis (PsO). The main aim of the study is to know how well zasocitinib (TAK-279) works in participants with active PsA based on their previous experience with specific treatments. The participants will be treated with either zasocitinib, or placebo. Participants will be in the study for up to 60 weeks.

A Study of Zasocitinib in Adults With Psoriatic Arthritis Who Have Not Taken Biologic Medicines
Recruiting
Psoriatic arthritis (PsA) is a chronic inflammatory disease that affects the joints and skin in people who have psoriasis (PsO). The main aim of the study is to know how well zasocitinib (TAK-279) works in participants with active PsA who have not previously been treated with biologic disease-modifying antirheumatic drugs. The participants will be treated with either zasocitinib, active comparator, or placebo. Participants will be in the study for up to 60 weeks.

A Study to Evaluate Safety, Tolerability, and Immunogenicity of V350A and V350B in Healthy Participants (V350-001).
Recruiting
Epstein Barr virus (EBV) is a virus which can cause infectious mononucleosis and is associated with certain kinds of cancer and multiple sclerosis. Researchers are looking for new ways to prevent disease related to EBV and have developed a new study vaccine (V350A and V350B). The main goal of this study is to learn about the safety and tolerability of V350A and V350B in healthy adults.

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
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

Testing the Addition of an Immunotherapy Drug, Cemiplimab (REGN2810), Plus Surgery to the Usual Surgery Alone for Treating Advanced Skin Cancer
Recruiting
This phase III trial compares the effect of adding cemiplimab to standard therapy (surgery with or without radiation) versus standard therapy alone in treating patients with stage III/IV squamous cell skin cancer that is able to be removed by surgery (resectable) and that may have come back after a period of improvement (recurrent). The usual treatment for patients with resectable squamous cell skin cancer is the removal of the cancerous tissue (surgery) with or without radiation, which uses hig... Read More

Immunotherapy After Surgery for People Who Have No Remaining Cancer Cells After Standard Treatment for Early-Stage Non-Small Cell Lung Cancer, INSIGHT Trial
Recruiting
This phase III trial compares durvalumab to the usual approach (patient observation) after surgery for the treatment of patients with early-stage non-small cell lung cancer. Immunotherapy with monoclonal antibodies, such as durvalumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. The usual approach for patients who are not in a study is to closely watch a patient's condition after surgery and to have regular visits wit... Read More

Enasidenib for Patients With Clonal Cytopenia of Undetermined Significance and Mutations in IDH2A Decentralized Trial
Recruiting
Study researchers think that a drug called enasidenib may help people with clonal cytopenia of undetermined significance (CCUS) because the drug blocks the mutated IDH2 protein, which may improve blood cell counts. The purpose of this study is to find out whether enasidenib is a safe and effective treatment for CCUS.
