Study Summary

This trial tests if a combo of drugs (ckm+pembrolizumab) can treat metastatic triple negative breast cancer. CKM drugs modify the immune system & tumor-related processes; celecoxib causes cell death & reduces blood vessel growth. Pembrolizumab helps the body's immune system attack cancer.

Who is the study for?
This trial is for adults with triple negative breast cancer that has spread or can't be surgically removed. They must have normal bilirubin levels, agree to use contraception, and not have had cancer treatment in the last 3 weeks. Patients should be able to take oral meds, have measurable disease, and a performance status indicating they are relatively active.Check my eligibility
What is being tested?
The trial tests chemokine modulation therapy (CKM) - rintatolimod with celecoxib and interferon alpha 2b - combined with pembrolizumab immunotherapy. CKM may modify immune responses and tumor growth while pembrolizumab could help the immune system fight cancer more effectively.See study design
What are the potential side effects?
Possible side effects include flu-like symptoms due to CKM therapy, potential gastrointestinal issues from celecoxib, fatigue, allergic reactions similar to other NSAIDs or drugs used in the protocol, as well as common immunotherapy-related side effects like inflammation.

Trial Design

2Treatment groups
Experimental Treatment
Group I: Cohort II (CMK, early pembrolizumab)Experimental Treatment8 Interventions
Patients receive rintatolimod IV, celecoxib PO, and interferon alpha-2b IV on days 0, 1, and 2 of week 1 and days 7, 8, and 9 of week 2 on study. Patients receive pembrolizumab IV on day 2 of week 1 and then every 3 weeks beginning in week 4 on study. Patients also undergo CT scan or MRI at screening and follow-up, undergo blood sample collection during screening and on study, and may undergo tumor biopsy at screening and follow-up.
Group II: Cohort I (CKM, pembrolizumab)Experimental Treatment7 Interventions
Patients receive rintatolimod IV, celecoxib PO, interferon alpha-2b IV on days 0, 1, and 2 of week 1 and days 7, 8, and 9 of week 2 on study. Patients receive pembrolizumab IV on day 9 and then every 3 weeks after that for up to 4 doses on study. Patients also undergo CT scan or MRI at screening and follow-up and undergo blood sample collection during screening and on study.
