Clinical Trial Summary

To learn if the combination of niraparib and dostarlimab can help to control advanced cancer that has spread to the brain.


Clinical Trial Description

Primary Objective: --To determine the intracranial objective response rate (ORR) of niraparib in combination with dostarlimab in patients with brain metastases. Secondary Objectives: - To determine the duration of intracranial response (DoR) of niraparib in combination with dostarlimab in patients with brain metastases. - To determine the intracranial ORR, defined as assessed by RANO-BM and iRANO. - To assess the systemic antitumor activity of niraparib in combination with dostarlimab in patients with brain metastases as defined by ORR, CBR (Stable Disease [SD]>6m+CR+PR), progression free survival (PFS) and overall survival (OS). - Evaluate the safety and tolerability of niraparib in combination with dostarlimab in patients with brain metastases. Explorative Objectives: - To assess predictive and pharmacodynamic (PD) markers of response. - To assess the immune-related effects of niraparib and dostarlimab. - To evaluate the effects of niraparib and dostarlimab on steroid, cranial radiation, and opiate pain medication use and seizure reduction. - To assess ctDNA in cerebrospinal fluid (CSF) in all participants, and explore relationship to matched blood and tissue samples, when available. - To explore biomarkers of response and resistance in CSF. - To evaluate niraparib and dostarlimab concentrations or pharmacokinetics (PK) - To screen for the presence of dostarlimab anti-drug antibodies (ADA) ;
