Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, uncontrolled hypertension, unstable angina pectoris, cardiac arrhythmia, interstitial lung disease, serious chronic gastrointestinal conditions associated with diarrhea, or psychiatric illness/social situations that would limit compliance with study requirements, substantially increase risk of incurring adverse events (AEs) or compromise the ability of the patient to give written informed consent

Patients who have previously received anti-CTLA-4 antibody therapy

Follow Up the median follow-up is 22 months. since the study was stopped early, the follow-up time frame for objective response was significantly reduced.

Summary

This trial is testing olaparib, a PARP inhibitor, with and without tremelimumab, an immunotherapy drug, to see if they are effective in treating patients with ovarian, fallopian tube, or peritoneal cancer that has returned.

Who is the study for?

This trial is for adults with recurrent high-grade ovarian, fallopian tube, or peritoneal cancer that's sensitive to platinum-based therapy. Participants must have a BRCA1/2 mutation and measurable disease. They should not have progressed on PARP inhibitors if used before and can't be pregnant. People with certain heart conditions, active infections, autoimmune diseases requiring recent treatment, or those on immunosuppressants are excluded.

What is being tested?

The study is testing the effectiveness of combining Olaparib (a PARP inhibitor) with Tremelimumab (an immunotherapy drug) versus using Olaparib alone in patients whose cancer has returned. It aims to see if this combination helps the immune system better attack cancer cells and prevents them from repairing themselves.

What are the potential side effects?

Possible side effects include allergic reactions similar to other drugs like Olaparib or Tremelimumab, symptoms from previous cancer treatments except hair loss and skin discoloration, increased risk of infection due to immune suppression by medications being tested.

Trial Design

2Treatment groups

Experimental Treatment

Active Control

Group I: Arm II (olaparib, tremelimumab)Experimental Treatment4 Interventions

Patients receive olaparib as in Arm I. Patients also receive tremelimumab IV over 60 minutes on day 1. Cycles of tremelimumab repeat every 4 weeks for 4 doses and then every 12 weeks for up to 2 years total in the absence of disease progression or unacceptable toxicity. Patients also undergo CT or MRI as well as blood sample collection throughout the trial.

Group II: Arm I (olaparib)Active Control4 Interventions

Patients receive olaparib PO BID in the absence of disease progression or unacceptable toxicity. Patients also undergo CT or MRI as well as blood sample collection throughout the trial.
