NCT05515575

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Progression free survival (PFS)

    Defined by RECIST 1.1. PFS is defined as the period from start of study treatment until recurrent or progressive of disease (POD) is objectively documented (taking as reference for progressive disease the smallest measurement recorded on study), death, or date of last study visit involving assessment of disease status.

    12 weeks

Secondary Outcomes (2)

  • Assess adverse events

    2 years

  • Progression free survival (PFS)

    24 weeks

Study Arms (1)

Niraparib

EXPERIMENTAL

This study will utilize Simon's two-stage design: 16 patients will be enrolled in the first portion of this study. If 4 or more patients are progression-free at 12 weeks, an additional 16 patients will be enrolled for a total of n = 32 patients enrolled.

Drug: Niraparib

Interventions

Each patient will receive niraparib daily in 21-day cycles until disease progression or unacceptable toxicity. Mandatory baseline tumor biopsies will occur during study screening, if feasible.
