Fuzuloparib Arsenic Trioxide Platinum Resistance Relapsed Ovarian Cancer

Официальное название

Fuzuloparib Plus Arsenic Trioxide in Patients With Platinum Resistance Relapsed Ovarian Cancer

Обзор

Ovarian cancer is the leading cause of death from gynecologic tumors in the western world. Most patients have relapses, and responses to subsequent therapies are generally short-lived. Currently, the population that can benefit from PARPi is mainly focusing on BRCAm, then homologous-recombination deficiency patients. Limited data revealed the ORR was only 3-4% in homologous recombination proficiency patients with PARPi therapy. New treatments are urgently needed to improve patient outcomes. To explore the efficacy and safety of Fuzuloparib in combination with Arsenic trioxide therapy in platinum-resistance relapsed Ovarian cancer patients.

Подробное описание

Ovarian cancer is the leading cause of death from gynecologic tumors in the western world. Most patients have relapses, and responses to subsequent therapies are generally short-lived. Currently, the population that can benefit from PARPi is mainly focusing on BRCAm, then homologous-recombination deficiency patients. Limited data revealed the ORR was only 3-4% in homologous recombination proficiency patients with PARPi therapy. New treatments are urgently needed to improve patient outcomes.

The investigators' studies have shown that combination therapy with Fuzuloparib and Arsenic trioxide demonstrated a synergistic anti-tumor effect in BRCAness/HR-proficiency ovarian cancer cells:

Firstly, CCK8 and clone formation assays showed that the combination of Fuzuloparib and Arsenic trioxide produced notable tumor cell growth inhibition than either single agent in SKOV3 and CAOV3 cells.

Further, the combination therapy resulted in significantly increased level of γ-H2AX and decreased level of RAD51 by IF.The investigators also found that combination therapy could remarkably induced cell apoptosis, which is associated with induction of cleave-PARP and reduction of p-AKT, when compared with either single drug. (Data not published) Therefore, the investigators hypothesis is that for those platinum-resistance relapsed patients who have received at least twice platinum-based chemotherapy, patients with combinate therapy will get 25% of ORR. And platinum-resistance in combination with Arsenic trioxide therapy is well tolerated.
