Merkel Cell Carcinoma clinical trials at UCSD

This Phase 1B/2 study is a multicenter, open-label, study of RP1 to investigate the (a) objective response rate, in addition to (b) safety and tolerability of RP1 for the treatment of advanced cutaneous malignancies in up to 65 evaluable organ transplant recipients. This will include patients with either previous renal, hepatic, heart, lung, or other solid organ transplantation or hematopoietic cell transplant and experiencing subsequent documented locally advanced or metastatic cutaneous malignancies. The study will enroll a total of 65 evaluable patients. Patients will participate up to approximately 3 years including a 28-day screening period, up to approximately 1 year treatment period, and a 2-year follow-up period.

The goal of this study is to learn if giving cemiplimab and vidutolimod together could be effective in treating advanced cancer. The main questions it aims to answer are: - How many participants' cancers respond to vidutolimod together with cemiplimab? - Is vidutolimod together with cemiplimab safe and well-tolerated? - How well does vidutolimod together with cemiplimab treat participants' cancer? Participants will receive trial treatment for up to 2 years. 30 days after stopping treatment, participants will have an end of treatment visit. After that visit, the trial staff will continue to follow up with participants about every 3 months, until the trial ends.
