Summary

This trial aims to test the safety and tolerance of a new drug called axatilimab when used together with olaparib, a standard treatment, in patients with specific types of breast cancer

See full description

Who is the study for?

This trial is for adults over 18 with HER2-negative metastatic breast cancer linked to BRCA1/2 or PALB2 mutations. They should have had no more than two prior chemotherapy treatments and must not be candidates for further endocrine therapy if their cancer is hormone receptor positive. Participants need a certain level of blood cells, liver function, and an ECOG performance score of ≤ 2.Check my eligibility

What is being tested?

The study tests the safety and effectiveness of combining axatilimab (an antibody) with olaparib (a PARP inhibitor), which is already used in treating this type of breast cancer. Axatilimab is new, while olaparib represents standard care.See study design

What are the potential side effects?

While specific side effects are not listed here, typical ones from antibodies like axatilimab may include allergic reactions or infusion-related issues. Olaparib can cause nausea, fatigue, blood cell count changes, and increased risk of infections.

Experimental Treatment

Group I: Axatilimab + OlaparibExperimental Treatment2 Interventions

A Bayesian Optimal Interval design will be used to establish the maximum tolerated dose of Axatilimab. Dose reduction and escalation will be per protocol. Participants will complete: * Baseline visit, tumor biopsy, and imaging * Imaging every 8 weeks * Window Phase: --Predetermined dose of Olaparib 2x daily, taken 12 hours apart for 14 days * Combination Treatment Phase: * Cycle 1 through Cycle 2: * Day 1 of 28 day cycle: Tumor biopsy * Days 1 and 15 of 28 day Cycle: Predetermined dose of Axalitimab 1x daily * Days 1 through 28 of 28 day cycle Predetermined dose of Olaparib 2x daily, 12 hours apart * Tumor biopsy after two weeks of Olaparib and at the end of Cycle 2 * Cycle 3 through End of Treatment: * Days 1 and 15 of 28 Day Cycle: Predetermined dose of Axalitimab 1x daily * Predetermined dose of Olaparib 2x daily, taken 12 hours apart * End of Treatment Visit with imaging * Follow Up: Every 6 months for 3 years. Imaging will be every 10 weeks.
