Fluzoparib (SHR3162) is a potent and orally activePARP1inhibitor (IC₅₀=1.46±0.72 nM, a cell‐free enzymatic assay) with superior antitumor activity. Fluzoparib selectively inhibits the proliferation of homologous recombination repair (HR)‐deficient cells, and sensitizes both HR‐deficient and HR‐proficient cells to cytotoxic agents. Fluzoparib exhibits good pharmacokinetic propertiesin vivoand can be used for BRCA1/2-mutant relapsed ovariancancerresearch^[1].

Fluzoparib (30 μM; 24 hour) increases the levels of γH2AX in a concentration‐dependent manner in both BRCA2‐deficient V‐C8 cells and BRCA1‐deficient MDA‐MB‐436 cells, but not in BRCA‐proficient V‐C8#13‐5 cells^[1].
Fluzoparib (10 μM; 24 hour) increases levels of both pCDK1 and cyclin B, indicating activation of the G2/M checkpoint in MDA‐MB‐436 cells^[1].
Fluzoparib (10 μM; 72 hour) increases the processing of caspase‐3, ‐8, and ‐9 concentration‐dependently, it induces G2/M arrest and apoptosis in HR‐deficient MDA‐MB‐436 cells cells^[1].
Fluzoparib is preferentially efficacious against HR‐deficient cells, such asBRCA1‐deficient (UWB1.289), MDA‐MB‐436,BRCA2‐deficient (V‐C8),BRCA1‐deficientBRCA2‐mutated (MX‐1) andBRCA1 hypermethylated (OVCAR‐8) cells with IC₅₀values of 0.51 μM, 1.57 μM, 0.053 μM, 1.57 μM, and 1.43 μM, respectively. The IC₅₀values for HR‐proficient cells (V‐C8#13‐5 and UWB1.289 BRCA1) are both >10 μM^[1].

Fluzoparib (oral gavage; 0.3, 1, or 3 mg/kg; single dose) exhibits a good pharmacokinetic profile in Female Balb/cA nude mice (5‐6 weeks old) mice bearing MDA‐MB‐436. After a single oral dose, fluzoparib is rapidly absorbed and rapidly cleared from blood at all dose levels; plasma concentrations of fluzoparib quickly reaches maximum within 2 hours. In contrast, concentrations of fluzoparib in tumor remains at high levels even at 24 hours after dosing (57.9 ng/g , 39.3 ng/g, and 85.6 ng/g for doses of 0.3, 1, and 3 mg/kg, respectively)^[1].
Fluzoparib (oral gavage; 30 mg/kg; 21 days) apparently inhibits the growth of tumor with an inhibition rate of 59% (day 21) at 30 mg/kg, and it does not cause significant loss of body weight in Nude mice bearing MDA‐MB‐436 (BRCA1‐deficient) model^[1].
Fluzoparib (3mg/kg) combines with Cisplatin, Paclitaxel, or Apatinib (oral gavage; BID; 21 days) causes growth inhibition with rates of 61.4%, 55.3%, and 72.8%, respectively.
Fluzoparib, Cisplatin, and Apatinib combination or Fluzoparib, Paclitaxel, and Apatinib combination can cause growth inhibition with rates of 84.9% and 75.6% (day 21), respectively in vivo.
The 2‐drug combination of Fluzoparib with cisplatin and The 3‐drug Fluzoparib, Cisplatin, and Apatinib combination lead to loss of body weight, whereas no apparent toxicity was observed in other combinations^[1].
