A Study of SGN-CEACAM5C in Adults With Advanced Solid Tumors
NCT06131840
Recruiting
This clinical trial is studying advanced solid tumors. Solid tumors are cancers that start in a part of your body like your lungs or liver instead of your blood. Once tumors have grown bigger in one place but haven't spread, they're called locally advanced. If your cancer has spread to other parts of your body, it's called metastatic. When a cancer has gotten so big it can't easily be removed or has spread to other parts of the body, it is called unresectable. These types of cancer are harder to... Read More

Testing the Addition of Anti-cancer Drug, ZEN003694, to the Usual Chemotherapy Treatment, Cetuximab Plus Encorafenib, for Colorectal Cancer
NCT06102902
Recruiting
This phase I trial tests the safety, best dose, and effectiveness of ZEN003694 in combination with cetuximab and encorafenib in treating patients with colorectal cancer that has not responded to previous treatment (refractory), that has come back after a period of improvement (relapsed), and that has spread from where it first started (primary site) to other places in the body (metastatic). ZEN003694 is a protein inhibitor that binds to BET proteins. When ZEN003694 binds to BET proteins, it disr... Read More

A Study of Bomedemstat (IMG-7289/MK-3543) Compared to Best Available Therapy (BAT) in Participants With Essential Thrombocythemia and an Inadequate Response or Intolerance of Hydroxyurea (MK-3543-006)
NCT06079879
Recruiting
This is a study evaluating the safety and efficacy of bomedemstat (MK-3543) compared with the best available therapy (BAT) in participants with essential thrombocythemia (ET) who have an inadequate response to or are intolerant of hydroxyurea.

Hyperbaric Oxygen Therapy for Ulcerative Colitis (HBOT-UC)
NCT05987852
Recruiting
Chronic intestinal hypoxia and accompanying mucosal inflammation is a hallmark of ulcerative colitis (UC). Hyperbaric oxygen therapy (HBOT) involves breathing 100% oxygen under increased atmospheric pressure to increase tissue oxygenation. Two small prospective randomized controlled trials have demonstrated that the delivery of HBOT to UC patients hospitalized for acute moderate to severe flares results in improved remission rates and avoidance of in-hospital progression to biologics, small mole...

This study will test the safety of a drug called PF-08046052/SGN-EGFRd2 in participants with advanced solid tumors. It will also study the side effects of this drug. A side effect is anything a drug does to the body besides treating the disease. Participants will have cancer that cannot be removed (unresectable) or has spread through the body (metastatic). This study will have three parts. Parts A and B of the study will find out how much PF-08046052/SGN-EGFRd2 should be given to participants.... Read More
