Ovarian Cancer
Conditions
Brief summary
To evaluate the efficacy and safety of JPI-547, a PARP/TNKS dual inhibitor in Platinum-resistant, advanced/relapsed ovarian cancer subjects previously treated with a PARP inhibitor
Interventions
DRUGJPI-547
Poly-(ADP-ribose) polymerase (PARP) & tankyrase (TNKS) inhibitor. * The investigational product (IP) will be administered once daily for 28 days (4 weeks) with 1 cycle. * 1 capsule (JPI-547 150 mg) will be administered once daily at the same time (e.g., a fixed time in the morning) in a fasted condition within 2 hours before or after a meal.

Intervention model description
This study will be conducted with subjects with HRD-positive, platinum-resistant, advanced/relapsed ovarian cancer with a history of ARP inhibitor treatment using Simon's optimal two-stage design. When the confirmed response is observed in ≥3 out of 18 subjects who are available for tumor assessment in Stage 1, the subjects will proceed with Stage 2. After additional enrollment of 40 subjects who are available for tumor assessment in Stage 2, the assessment will be conducted to identify that the confirmed response is observed in ≥11 out of the final 58 subjects.
