Background:
The BEATcc trial demonstrated the combination of atezolizumab plus bevacizumab and platinum regimen as first-line treatment for recurrent, or metastatic cervical cancer significantly improves progression-free survival (PFS) and overall survival (OS) regardless of PD-L1 status. ALTER-GO-020 is an ongoing open-label, single-arm, multi-cohort phase II study evaluating the combination of anlotinib (a multitarget anti-angiogenic TKI) and penpulimab (anti-PD-1 antibody) as a chemotherapy-free regimen for patients (pts) with recurrent or metastatic gynecological cancer. Here, we report the preliminary results of the cohort of patients with recurrent or metastatic cervical cancer from ALTER-GO-020.
Methods:
Eligible pts were histologically confirmed persistent, recurrent, or metastatic cervical cancer (including adenocarcinoma, adenosquamous carcinoma, or squamous-cell carcinoma), not amenable to curative treatment, and had no prior systemic treatment for metastatic, persistent, or recurrent disease. Pts were treated with anlotinib (12mg, po qd, d1-14, q3w) plus penpulimab (200mg, IV, d1, q3w) until disease progression or unacceptable toxicity. The primary endpoint was objective response rate (ORR) and the secondary endpoints included PFS, duration of response (DOR), disease control rate (DCR), OS and safety.
Results:
From May 2022 to Nov 2023, 17 pts were enrolled. The median age was 52 years (range, 31-70), 65% of pts were squamous-cell carcinoma, 88% received previous chemoradiotherapy with or without surgery, and 71% had previously received neoadjuvant/adjuvant platinum-containing chemotherapy. As of date cutoff (Dec, 2023), the median follow-up time was 6.8 months (range, 1.4-18.3 months). In the efficacy analysis (n=17), the preliminary ORR was 58.8% (95% CI: 32.9%-81.6%), DCR was 88.2% (95% CI: 63.6%-98.5%). The mPFS was 11.0 months (95% CI: 5.4-16.7 months). The mOS was not reached. Treatment-related adverse events (TRAEs) of any grade occurred in all 17 pts, in which 8 (47.1%) were grade ≥3. The most common grade ≥3 TRAEs were hypertension (29.4%), hand foot syndrome (11.8%), fatigue (11.8%), and diarrhea (5.9%). TRAEs led to dose reduction and interruption were 29.4%, and 35.3% of pts, respectively. No TRAEs leading to death.
Conclusions:
The preliminary results demonstrated that anlotinib plus penpulimab as a first-line therapy for persistent, recurrent, or metastatic cervical cancer showed promising antitumor efficacy and manageable safety profile. Clinical trial information: NCT05028504.
