Testing the Effect of M1774 on Hard-to-Treat Refractory SPOP-mutant Prostate Cancer
Recruiting
This phase II trial tests how well M1774 works in treating patients with prostate cancer that does not respond to treatment (refractory) and that has a mutation in the gene responsible for making the speckle type BTB/POZ protein (SPOP). M1774 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving M1774 may be able to shrink or stabilize refractory SPOP-mutant prostate cancer.

A Study With Tovorafenib (DAY101) as a Treatment Option for Progressive, Relapsed, or Refractory Langerhans Cell Histiocytosis
Recruiting
This phase II trial tests the safety, side effects, best dose and activity of tovorafenib (DAY101) in treating patients with Langerhans cell histiocytosis that is growing, spreading, or getting worse (progressive), has come back (relapsed) after previous treatment, or does not respond to therapy (refractory). Langerhans cell histiocytosis is a type of disease that occurs when the body makes too many immature Langerhans cells (a type of white blood cell). When these cells build up, they can form...

DOR/ISL in HIV-1 Antiretroviral Treatment-naïve Participants (MK-8591A-053)
Recruiting
This is a randomized, active-controlled, double-blind clinical study designed to evaluate the antiretroviral activity, safety, and tolerability of doravirine/islatravir (DOR/ISL [MK-8591A]) in treatment-naïve participants with human immunodeficiency virus type 1 (HIV-1) infection. It is hypothesized that DOR/ISL is non-inferior to bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF) as assessed by the percentage of participants with HIV-1 ribonucleic acid (RNA) <50 copies/mL at Week 48.
