Phase I/II Trial Investigating the Safety, Tolerability, Pharmacokinetics, Immune and Clinical Activity of SX-682 in Combination With BinTrafusp Alfa (M7824 or TGF-beta "Trap"/PD-L1) With CV301 TRICOM in Advanced Solid Tumors (STAT)

Detailed Summary

Background: Combination immunotherapy techniques are being explored to improve responses and enhance benefits in people with cancer. Researchers want to see if this type of treatment can help people with advanced solid tumors. Objective: To find a safe dose of SX-682 in combined treatment with Bintrafusp alfa and BN-CV301 vaccines and to see if this treatment will cause tumors to shrink. Eligibility: Adults age 18 and older with metastatic cancer may be eligible for the first part of the trial. Adults age 18 and older with metastatic triple negative breast cancer or p16 negative head and neck squamous cell cancer, and who are not candidates for curative surgery may be eligible for the second part of the trial. Design: Participants will be screened under a separate protocol. Participants may have tumor biopsies. They will have physical exams. Their symptoms and medicines will be reviewed. They will have blood tests. They will have electrocardiograms to evaluate their heart. Participants will have imaging scans of the chest, abdomen, and pelvis. They may have a procedure where a small tube with a tiny video camera is put into the nose to look at the throat if they have head and neck cancers. Participants will get bintrafusp alfa through an intravenous catheter. For this, a small tube is put into an arm vein. They will get BN-CV301 vaccines as injections in the arm or thigh. They will take SX-682 by mouth twice a day. They will take the study drugs up to 2 years. They will keep a medicine diary. Participants will have study visits every 2 weeks. They will have 1 or 2 follow-up visits within 30 days after they stop treatment. Then they will be monitored by phone or email for 2 years.
