Official title

Combination Therapy of Niraparib and Irinotecan in Cancers With Mutations in DNA Repair Genes

Brief summary

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

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.
