Study on Docetaxel and SX-682 for Recurrent/Metastatic Head and Neck, Salivary Gland, and Advanced Prostate Cancer

Sponsor: National Cancer Institute (NCI)

Sponsor score: 0

ClinicalTrials ID:NCT07667400

This clinical trial is testing a new combination of drugs, SX-682 and docetaxel, to see if they can help treat head and neck cancers, salivary gland cancers, and advanced prostate cancer that have returned or spread after treatment.

Patient Parameters

Program Overview

The study aims to evaluate a new drug, SX-682, combined with an existing drug, docetaxel (DTX), for treating head and neck cancers, salivary gland cancers, and advanced prostate cancer. These cancers often have poor survival rates when they spread or return after treatment, so better treatments are needed. Participants will take SX-682 as a tablet and receive DTX through an IV. The study will monitor the safety and effectiveness of this combination over several cycles of treatment.

Description

This study focuses on improving treatment for certain cancers that have returned or spread after initial treatment. It involves two drugs: SX-682, a new drug that may help the immune system fight cancer, and docetaxel (DTX), a drug already used to treat these cancers. The study will test if combining these drugs can improve outcomes for patients with head and neck cancers, salivary gland cancers, and advanced prostate cancer.

Participants will take SX-682 as a tablet twice daily for 11 days in each 3-week cycle. They will also receive DTX through an IV on the 8th day of each cycle. This treatment will continue for up to 6 cycles, depending on how well the cancer responds and if there are any side effects.

The study will have two phases. Phase I will determine the safest dose of SX-682 to use with DTX. Phase II will evaluate how effective the combination is at shrinking tumors. Participants will have regular check-ups, including blood tests and scans, to monitor their health and the treatment's effects.

After completing the treatment cycles, participants will have follow-up visits to check their progress and any long-term effects of the treatment. These visits will continue for up to 5 years.
