Or B. In combination with bevacizumab for the maintenance treatment of adult patients with advanced (FIGO stage III and IV) epithelial ovarian, fallopian tube, or primary peritoneal cancer who are in complete or partial response to first-line platinum-based chemotherapy, and whose cancer is associated with homologous recombination deficiency (HRD) positive status defined by either: Ba. a deleterious or suspected deleterious BRCA mutation, and/or Bb. genomic instability. Or C. Adult patients with deleterious or suspected deleterious germline or somatic BRCA mutated recurrent epithelial ovarian, fallopian tube, or primary peritoneal cancer who are in complete or partial response to platinum-based chemotherapy, for use as maintenance treatment.

The bioequivalence of Test product (T) Olaparib tablets 150 mg of Hetero Labs Limited, India with Reference product (R) LYNPARZA 150 mg film tabletten (Olaparib) of AstraZeneca AB SE-151 85 Sodertalje Schweden will be assessed by a statistical comparison of various pharmacokinetic parameters derived from the plasma concentration-time curves of Olaparib.Timepoint: The Pharmacokinetic parameters derived from the plasma concentration-time curves of Olaparib will be done as follows: In each study period the blood samples will be collected as following. On 6, 7, 8, 14, 15 and 16: A single pre-dose [00.00 hour] blood sample of 4 mL each will be collected within 05 minutes prior to dosing of morning doses. On Day 8 (morning dose) and 16 (morning dose): The post dose blood samples of 4 mL each will be drawn at 0.25, 0.50, 0.75, 1.00, 1.25, 1.50, 1.75, 2.00, 2.33, 2.67, 3.00, 4.00, 5.00, 6.00, 8.00, 10.00 and 12.00 hours in each study period.
