KEY TAKEAWAYS
- The phase 2 trial aimed to investigate the efficacy of CAM plus FAM vs CAM alone or chemo in improving OS for pts with R/M CC.
- Researchers noticed that the improved OS with CAM plus FAM supports its potential as a novel treatment option for pts with R/M CC.
The prognosis of recurrent or metastatic cervical cancer (R/M CC) remains dismal, given the paucity of effective treatment options. The randomized, open-label, phase 2 trial showed that (CAM, an anti-PD-1 antibody) plus famitinib (FAM, a multi-targeted TKI against VEGFR2/3) improved antitumor activity compared with CAM alone or the investigator’s choice of chemotherapy (INV chemo) in patients (pts) with recurrent or metastatic cervical cancer (R/M CC) (2023 ESMO LBA44).
Xiaohua Wu and the team aimed to assess the survival outcomes of pts with R/M CC treated with CAM plus FAM, CAM alone, or INV chemo.
They performed an inclusive analysis, enrolling 194 pts with R/M CC who had experienced relapse or progression after platinum-based chemotherapy. Patients were randomized to receive CAM (200 mg IV Q3W) with (n=105) or without (n=54) FAM (20 mg PO QD) or INV chemo (n=35) every 3 weeks. The randomization was stratified by histologic subtyping (squamous cell carcinoma vs. non-squamous cell carcinoma) and PD-L1 expression (CPS ≥1 vs. <1).
About 77.8% of enrolled pts had squamous cell carcinoma (SCC), 63.9% were PD-L1 positive, and 31.4% received prior targeted therapy. With a median follow-up of 9.9 months, CAM + FAM achieved improved ORR and prolonged PFS compared with CAM and INV chemo (ORR per INV, 42.9% vs 22.2% and 14.3%; median PFS per INV, 8.1 vs 4.1 and 2.9 months); however, OS data were immature.
As of the data cutoff on Sep 25, 2023, for the current analysis, the median follow-up was 13.6 months (IQR, 9.3–18.0). A total of 91 deaths were recorded, including 43 (41.0%) in the CAM + FAM cohort, 27 (50.0%) in the CAM cohort, and 21 (60.0%) in the INV chemo cohort.
The median OS was 20.6 months (95% CI: 15.7–not reached [NR]) in CAM + FAM cohort, 14.9 months (95% CI: 12.6–NR) in CAM cohort, and 13.9 months (95% CI: 7.4–20.0) in INV chemo cohort. The risk of death in the CAM + FAM cohort was reduced by 33% compared with CAM cohort (HR = 0.67 [95% CI: 0.41–1.10]) and by 45% compared with the INV chemo cohort (HR = 0.55 [95% CI: 0.32–0.95]). OS rate at 12 months was 76.1% (95% CI: 66.7–83.2), 67.2% (95% CI: 52.6–78.2), and 58.4% (95% CI: 39.3–73.4) with CAM + FAM, CAM, and INV chemo, respectively. No new safety signals were observed.
The study concluded that these results further support the regimen of CAM plus FAM as a novel treatment option for pts with R/M CC.
