PHASE I

• Escalade de dose– Cohortes 3-6 patients– Dose de 30 à 400 mg/j– Expansion 15 malades a DMTØ60 patientesØDMT : 300 mg/j

• Partie B : 40 patients à DMT– Ovaire résistant et cancer de prostate

• DLT :– grade 3 fatigue (one patient given 30 mg/day),– grade 3 pneumonitis (one given 60 mg/day), and– grade 4 thrombocytopenia (two given 400 mg/day).

• Common treatment-related toxic effects, predominantly grade 1 or 2 :– anaemia (48%), – nausea (42%), – fatigue (42%), – thrombocytopenia (35%), – anorexia (26%), – neutropenia (24%), – constipation (23%), – Vomiting (20%)

• Pharmacokinetics :– dose proportional and – the mean terminal elimination half-life was 36·4 h ( 32·8-46·0).

• Pharmacodynamic analyses confirmed– PARP inhibition exceeded 50% at doses greater than 80 mg/day– antitumour activity was documented beyond doses of 60

mg/day.

• 8/20 (40%) BRCA1 or BRCA2 mutation carriers with ovariancancer had RECIST partial responses,

• 2/4 (50%) of mutation carriers with breast cancer.

Study hypothesis

Niraparib, as a selective PARP1/2 inhibitor, will provide a clinical benefit to all patients who have platinum-sensitive recurrent ovarian cancer who are in response to platinum,

regardless of gBRCA mutation status

• The continuum of clinical activity according to platinum sensitivity in patientswith tumors bearing BRCA mutations was further demonstrated byprogression-free survival (PFS) analysis.

• The mPFS was 6.3 months (95% CI 5.4, 8.2) overall. In comparison, PFS inpatients with platinum-sensitive, -resistant and –refractory disease was 11.0months (95% CI 5.5, NE), 5.4 months (95% CI 1.8, 10.1), and 5.7 months (95% CI1.8, NE), respectively
