What this Trial Is About

The purpose of this phase 1 clinical trials is to determine whether niraparib (a Poly (ADP-ribose) polymerase inhibitor (PARPi)) can be safely combined with irinotecan with manageable toxicity and reasonable efficacy. Emerging evidence suggest that PARPi is an effective therapeutic strategy in a wider subset of solid tumors that may have defective homologous recombination (HR) or DNA repair gene mutations. BReast CAncer gene (BRCA), partner and localizer of BRCA2 (PALB2), and various other DNA repair germline mutations predispose carriers to cancers of the breast, ovaries, pancreas, prostate and melanoma. A number of preclinical studies have demonstrated that PARP inhibitors can work as chemopotentiators. There is significant interest in this combination, and the recommended phase II dose will be used in the upcoming NCI ComboMatch trial.

  • Solid tumors responsive to topoisomerase I inhibitors, including gastrointestinal, breast, and ovarian cancers, with BRCA1, BRCA2, ATM, or PALB2 mutations confirmed by approved testing
  • At least one measurable tumor lesion by RECIST 1.1 criteria
  • Advanced solid tumors without curative treatment options
  • At least 3 weeks or 5 half-lives since last anticancer therapy, with recovery from toxicities to less than grade 2
  • Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
  • Adequate organ function based on blood counts and liver, kidney tests
  • Recovery from prior treatment toxicities to less than grade 2, except some mild chronic side effects

Not Eligible

You will not qualify if you...

  • Any significant medical condition or lab abnormalities posing unacceptable risk
  • Allergic reaction to PARP inhibitors or irinotecan
