Efficacy and safety of sintilimab plus albumin-bound-paclitaxel in recurrent or metastatic cervical cancer: a multicenter, open-label, single-arm, phase II trial.

ABSTRACT:

Background

Sintilimab is an antibody against programmed cell death protein 1. We assessed the efficacy and safety of sintilimab plus albumin-bound (nab)-paclitaxel for the treatment of recurrent or metastatic cervical cancer.

Methods

This multicenter, open-label, single-arm, phase II study (ClinicalTrials.gov identifier NCT04341883) enrolled patients with recurrent or metastatic cervical cancer who progressed after at least one line of systemic therapy. The patients received sintilimab 200 mg and nab-paclitaxel 260 mg/m² body surface area every 3 weeks. The primary endpoint was objective response rate (ORR) assessed by investigators per Response Evaluation Criteria in Solid Tumors version 1.1. Key secondary endpoints were progression-free survival (PFS), overall survival (OS), duration of response (DoR), and safety.

Findings

From January 13, 2020 to February 21, 2022, 27 patients were enrolled and received treatment. Median patient age was 50 years (range, 34-68 years). By data cut-off (May 22, 2022), in intention-to-treat population, ORR was 44.4% (95% CI, 24.4%-64.5%). The disease control rate was 88.9% (95% CI, 70.8%-97.6%). Median PFS was 5.2 months (95% CI, 2.7-7.7 months). Median DoR was 3.8 months (95% CI, 0.7-6.9 months), and median OS was 13.1 months (95% CI, 5.8-20.4 months). Treatment-related grade 3 or 4 adverse events (AEs) occurred in 44.4% of the patients, and the most common AEs were decreased neutrophil count (22.2%), decreased white blood cell count (14.8%), and anemia (7.4%). The most common potential immune-related AEs were grade 1-2 hypothyroidism (18.5%), neutropenia (11.1%), and rash (7.4%).

Interpretation

Sintilimab plus nab-paclitaxel treatment shows promising antitumor activity and manageable toxicity in patients with advanced cervical cancer. Larger randomized controlled trials are required for validation.

Project description:BackgroundNeoadjuvant chemotherapy may be considered for patients with ovarian cancer (OC) whose tumors are deemed unlikely to be completely cytoreduced to no gross residual disease (R0) or who are poor surgical candidates. This Ib/II study was designed to assess the efficacy and safety of nanoparticle albumin-bound paclitaxel (nab-paclitaxel) plus carboplatin as neoadjuvant chemotherapy for stages III-IV, unresectable OC.MethodsEligible patients with stage III-IV, unresectable OC were enrolled in this phase Ib/II study. All patients received neoadjuvant nab-paclitaxel (260 mg/m2, day 1, every 3 weeks) plus carboplatin (AUC 5, day 1, every 3 weeks) for 3 cycles before surgery, followed by 3-6 cycles of adjuvant chemotherapy. The phase Ib primary endpoint was safety; the phase II primary endpoint was the R0 resection rate. Secondary endpoints were progression-free survival (PFS), overall survival (OS), objective response rate (ORR), and safety (for all populations).ResultsSixty-two patients were enrolled and were given neoadjuvant therapy treated between October 2019 and December 2020, of whom 9 were in the phase Ib portion and 53 in the phase II portion. A total of 53 patients underwent surgery with an R0 resection rate of 73.6% (95% CI, 59.7-84.7%). With a median follow-up of 17.5 (range 0.7-36.7) months, for all patients, the best ORR was 83.9% (95% CI, 71.7-92.4%) with 47 partial responses, the median PFS was 18.6 (95% CI, 13.8-23.3%) months, and median OS was not reached. During the neoadjuvant chemotherapy, treatment-related adverse events (TRAEs) of any grade occurred in 91.9% (57/62) of all patients. The most common hematologic TRAEs were neutropenia (55/62, 88.7%), and non-hematologic toxicity was alopecia (36/62, 58.1%). Forty-nine patients (79.0%) experienced at least one grade 3-4 TRAEs, with the most common was neutropenia (44/62, 71.0%). Besides, delays in neoadjuvant chemotherapy and surgery due to AEs were observed in 9 (1 in phase Ib; 8 in phase II) and 7 (phase II) patients, respectively.ConclusionsThe study demonstrated an encouraging efficacy and manageable safety profile of neoadjuvant chemotherapy nab-paclitaxel plus carboplatin in stage III-IV, unresectable OC. In addition, AEs resulting in chemotherapy and surgery delays should be cautiously considered in this clinical setting.Trial registrationClinicalTrials.gov, ChiCTR1900026893.

Project description:BackgroundNanoparticle albumin-bound paclitaxel (nab-PTX) has shown non-inferiority to paclitaxel (PTX) as second-line therapy for advanced gastric cancer (AGC) with fewer infusion-related reactions. The efficacy and safety of nab-PTX plus ramucirumab (RAM) was reported in a phase II trial; however, there is no randomized trial comparing this regimen with PTX plus RAM in patients with AGC. This retrospective study aimed to investigate the efficacy and safety of nab-PTX plus RAM versus PTX plus RAM in patients with AGC.MethodsThis study included patients with AGC who received nab-PTX plus RAM from September 2017 to January 2019 or PTX plus RAM from June 2015 to August 2017 as second-line chemotherapy in our hospital.ResultsA total of 113 and 138 patients who received nab-PTX plus RAM and PTX plus RAM, respectively, were analyzed. Median progression-free survival (PFS) was 3.9 months (95% confidence interval [CI]: 3.4-4.3) in the nab-PTX plus RAM group and 3.9 months (95% CI: 3.1-4.7) in the PTX plus RAM group (hazard ratio [HR]: 1.08; 95% CI: 0.83-1.40; P = 0.573). Median overall survival (OS) was 10.9 months (95% CI: 9.3-12.7) in the nab-PTX plus RAM group and 10.3 months (95% CI: 8.5-12.0) in the PTX plus RAM group (hazard ratio: 0.82; 95% CI: 0.61-1.10; P = 0.188). In patients with moderate/massive ascites, favorable outcomes for progression-free survival were observed in the nab-PTX plus RAM group compared with the PTX plus RAM group. Although anemia and fatigue (any grade) were more frequent in the nab-PTX plus RAM group, discontinuation of study treatment was not increased in the nab-PTX plus RAM group. There was no occurrence of hypersensitivity reaction in the nab-PTX plus RAM group, while two patients (1.4%) experienced grade 3 hypersensitivity reactions in the PTX plus RAM group.ConclusionsThe combination of nab-PTX plus RAM showed a similar efficacy and safety profile to PTX plus RAM as second-line treatment for patients with AGC.
