Testing the Role of DNA Released From Tumor Cells Into the Blood in Guiding the Use of Immunotherapy After Surgical Removal of the Bladder, Kidney, Ureter, and Urethra for Urothelial Cancer Treatment, MODERN Study
Recruiting
This phase II/III trial examines whether patients who have undergone surgical removal of bladder, kidney, ureter or urethra, but require an additional treatment called immunotherapy to help prevent their urinary tract (urothelial) cancer from coming back, can be identified by a blood test. Many types of tumors tend to lose cells or release different types of cellular products including their DNA which is referred to as circulating tumor DNA (ctDNA) into the bloodstream before changes can be seen...

A Study of Nemtabrutinib Plus Venetoclax vs Venetoclax + Rituximab (VR) in Second-line (2L) + Relapsed/Refractory (R/R) Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma (CLL/SLL) (MK-1026-010/BELLWAVE-010).
Recruiting
The purpose of this study is to assess the safety and tolerability and to confirm the dose of nemtabrutinib in combination with venetoclax in participants with R/R CLL/SLL. The primary study hypotheses are that the combination of nemtabrutinib plus venetoclax is superior to VR with respect to progression-free survival (PFS) per 2018 International Workshop on Chronic Lymphocytic Leukemia (iwCLL) criteria as assessed by blinded independent central review (BICR).
