Summary

This trial is testing how well a combination of dostarlimab and cobolimab works in treating advanced cervical cancer that has spread or come back.

Who is the study for?

This trial is for adults with measurable, recurrent or metastatic cervical cancer. They must have good organ function and performance status, no severe prior treatment side effects, and not be pregnant or breastfeeding. Those previously treated for hepatitis C can join if cured. Exclusions include past immune checkpoint inhibitor therapy, recent chemo or radiotherapy, active autoimmune diseases, HIV/AIDS, current serious illnesses, use of immunosuppressants or live vaccines recently.

What is being tested?

The study tests the effectiveness of combining two drugs: Dostarlimab and Cobolimab in treating advanced cervical cancer that has spread (metastatic) or returned after treatment (recurrent). The goal is to see how well these drugs work together against this type of cancer.

What are the potential side effects?

Potential side effects may include allergic reactions similar to those from compounds related to Dostarlimab and Cobolimab. There's also a risk of worsening autoimmune disease symptoms due to the immune-stimulating nature of the treatments.

Experimental Treatment

Group I: Cohort B: Immunotherapy ExposedExperimental Treatment2 Interventions

14 Participants will complete study procedures as follows: * Baseline visit. * Imaging tests at baseline visit, at week 9, and then every 12 weeks. * Cycle 1 through End of Treatment (up to 2 years of treatment): • Day of 21 Day cycle: Predetermined dose of Dostarlimab 1x daily. Predetermined dose of Cobolimab 1x daily. * End of Treatment visit with blood tests and imaging tests. * Follow Up Period: Every 3 months for 2 years and then every 6 months for an additional 5 years. Includes imaging tests. If \>= 2 participants with objective responses, then 23 additional participants will be enrolled.

Group II: Cohort A: Immunotherapy NaiveExperimental Treatment2 Interventions

10 Participants will complete study procedures as follows: * Baseline visit. * Imaging tests at baseline visit, at week 9, and then every 12 weeks. * Cycle 1 through End of Treatment (up to 2 years of treatment): • Day 1 of 21 Day cycle: Dostarlimab 1x daily and Cobolimab 1x daily. * End of Treatment visit with blood tests and imaging tests. * Follow Up Period: Every 3 months for 2 years and then every 6 months for an additional 5 years.
