Official title

Phase II Study of Niraparib in Soft Tissue Sarcoma Patients With Altered DNA Damage Repair

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The purpose of this study is to test whether the study drug, niraparib, is effective against unresectable and/or metastatic soft tissue sarcoma with DDR mutations. The researchers will also study whether niraparib is safe and causes few or mild side effects, and whether there are groups of DDR mutations in soft tissue sarcoma cells that respond better to treatment with niraparib.
