Chiauranib Plus Weekly Paclitaxel in Patients with Platinum-refractory or Platinum-resistant Recurrent Ovarian Cancer

Phase 3

Recruiting

• Conditions: Paclitaxel; Chiauranib; Ovarian Cancer; Relapsed or Refractory
• Interventions: Drug: Placebo; Drug: chiauranib; Drug: Paclitaxel

• Registration Number: NCT04921527
• Lead Sponsor: Chipscreen Biosciences, Ltd.

Brief Summary

This randomized, double-blind, 2-arm study will evaluate the efficacy and safety of Chiauranib plus weekly paclitaxel versus placebo plus weekly paclitaxel in patients with Platinum-refractory or Platinum-resistant Recurrent ovarian cancer.

Detailed Description

Chiauranib is a novel orally active multi-target inhibitor that simultaneously inhibits the angiogenesis-related kinases (VEGFR2, VEGFR1, VEGFR3, PDGFRa and c-Kit), mitosis-related kinase Aurora B and chronic inflammationrelated kinase CSF-1R in a high potency manner with the IC50 at a single-digit nanomolar range. In particular, Chiauranib showed very high selectivity in the kinase inhibition profile with little activity on off-target non-receptor kinases, proteins, GPCR and ion channels, indicative of a better drug safety profile in terms of clinical relevance.

Patients will be randomized to receive treatment with either paclitaxel + Chiauranib or paclitaxel + placebo. Paclitaxel will be repeated every 21 days for a maximum of 6 cycles. Patients with objective response/stable disease after completing 6 courses of chemotherapy will continue Chiauranib or placebo until progression.
