Abstract 289MO

Background

Fruquintinib (F, a highly selective VEGFR inhibitor) plus sintilimab (S, an anti-PD-1 monoclonal antibody) showed promising antitumor activity in both pre-clinical and clinical studies. Here, we reported the results of F plus S from CC cohort in an open-label, multicenter, single-arm phase 2 study.

Methods

Pts with pathologically confirmed advanced CC who had failed at least first-line platinum-containing treatment, or experienced intolerable toxicity during treatment, or were unable to receive standard therapy were eligible. Eligible pts received F (5 mg, 2 weeks [wk] on/1 wk off, orally, once daily) plus S (200 mg, IV, every 3 wk) in 21-day cycles, until disease progression or unacceptable toxicity. Treatment of S was allowed for up to 24 months (mo). The primary endpoint was ORR per RECIST v1.1.

Results

As of May 30, 2023, 34 pts were successfully enrolled and received F plus S, median follow-up duration was 16.4 mo. Median (range) age was 56 (26.2, 73.7) yrs. 6 pts (17.6%) were treatment naïve (naïve pts); 28 pts (82.4%) had received at least first-line treatment (treated pts), including bevacizumab (5/28), for advanced disease. 25 pts (73.5%) had received pelvic radiation therapy. There were 24 pts (70.6%) with PD-L1 status of CPS ≥1. Among tumor evaluable naïve and treated pts, confirmed ORR (cORR) were 50.0% (PR 3/6) and 29.6% (CR 1/27 and PR 7/27); median TTR were 2.7 and 3.1 mo; DCR were both 100%. In naïve (N=6) and treated (N=28) pts, mPFS were 10.3 and 8.2 mo, 15mo-OS rate were 83.3% and 70.0%. In tumor evaluable treated pts stratified by CPS ≥1 vs <1 (N= 17 vs 8), cORR was 41.2% vs 12.5%; in treated pts (N=18 vs 8), mPFS was 19.4 vs 5.2 mo; mOS was not reached vs 13.9 mo, 15mo-OS rate was 76.0% vs 50.0%. All pts experienced TEAEs, and the most common TEAEs included proteinuria (64.7%), hypothyroidism (61.8%), asthenia (44.1%), hyperthyroidism (44.1%), palmar-plantar erythrodysaesthesia syndrome (44.1%), anaemia (41.2%) and urinary tract infection (41.2%).

Conclusions

F plus S provided favorable efficacy in advanced CC pts, especially for treated PD-L1 CPS ≥1 pts. This combination treatment also showed manageable toxicity profile consistent with that seen in other cohorts.
