NCT03225547
This is a Phase II study of pembrolizumab plus mifepristone in advanced breast cancer patients. The study will include a safety lead in of ten patients. Patients who are deemed eligible and have signed informed consent will be treated with pembrolizumab at a fixed dose of 200 mg intravenously on day 1 of each 21 day cycle for each dose level. Mifepristone 300mg PO be administered daily starting the week prior to pembrolizumab. Once the safety of the combination is confirmed (study will be paused at least 6 weeks after first 10 patients are enrolled for safety evaluation), dose expansion cohorts will be performed in parallel for two cohorts: cohort 1 in triple-negative breast cancer and cohort 2 in hormone receptor positive breast cancer.
NCT04711824
This study is a Phase I/II study evaluating the safety and effectiveness of focused radiation therapy (radiosurgery) together with olaparib, followed by immunotherapy, for patients with brain metastases from triple negative or BRCA-mutated breast cancers. This study will have a Phase I portion in which subjects will be enrolled based on 3+3 dose escalation rules. Three dose levels of olaparib will be studied. Cycle 1 of study treatment will consist of Olaparib given twice daily concurrently with stereotactic radiosurgery (SRS). Olaparib will start one week prior to SRS and continue during and following SRS (1-5 fractions) for up to 28 days total. The number of doses of Olaparib will be dependent on how long it takes a subject to recover from SRS (ideally the subject will be off steroids, if they are required, at the start of Cycle 2, with exceptions outlined later in this section). Once the subject has recovered from SRS (based on investigator discretion) that will be considered the DLT period. Cycle 2 will be initiated with physician's choice systemic therapy and durvalumab. Cycle 2+ will equal 21 days. During Cycles 2 and 3, physician's choice systemic monotherapy will be given along with durvalumab per protocol. Each cycle will last 21 days. Imaging to evaluate intracranial and extracranial disease will be performed after Cycle 3, and subjects with response will continue with the systemic therapy and durvalumab until progression (intracranial or extracranial), unacceptable toxicity or death.
