Pembrolizumab Plus CA-4948 for the Treatment of Patients With Progressive Metastatic Urothelial Cancer Despite Prior Immunotherapy
NCT06439836
Recruiting
This phase I trial tests the safety, side effects, best dose, and effectiveness of emavusertib (CA-4948) in combination with pembrolizumab in treating patients with urothelial cancer that has spread from where it first started to other places in the body (metastatic) and that has a resistance to PD-1/PD-L1 immune checkpoint inhibitors. CA-4948, a kinase inhibitor, may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies,... Read More

Transcranial Magnetic Stimulation for Chronic Neuropathic Pain
NCT05593237
Recruiting
Chronic neuropathic pain is defined as pain caused by a lesion or disease of the somatosensory nervous system. It is highly prevalent, debilitating, and challenging to treat. Current available treatments have low efficacy, high side effect burden, and are prone to misuse and dependence. Emerging evidence suggests that the transition from acute to chronic neuropathic pain is associated with reorganization of central brain circuits involved in pain processing. Repetitive transcranial magnetic stim... Read More
