Sponsor's own description

This is a prospective, interventional, single-arm, open-label, phase II study to evaluate the safety and efficacy of niraparib monotherapy as neoadjuvant therapy in patients with advanced ovarian cancer, primary peritoneal cancer, fallopian tube cancer ((FIGO stage III or IV), who had low likelihood of achieving R0 cytoreduction by imaging assessment or laparoscopic evaluation, or cannot tolerate PDS by poor conditions.
