Apatinib with etoposide capsules as a third- or further-line therapy for extensive-stage small cell lung cancer: an open-label, multicenter, single-arm phase II trial.

ABSTRACT:

Background

Patients with extensive-stage small-cell lung cancer (ES-SCLC) have a particularly poor prognosis. And the treatment options for patients with relapsed or refractory ES-SCLC are limited. Thus, we conducted an open-label, multicenter, single-arm phase II clinical trial to assess the efficacy and safety of apatinib plus etoposide capsules as the third- or further-line treatment in ES-SCLC patients.

Methods

Patients with ES-SCLC who experienced disease progression following 2 to 3 previous therapies from 11 medical centers in China were enrolled to receive apatinib (250 mg/d, continuously) and etoposide capsules (50 mg/d, on day 1-21, per 28 days). The treatment continued until disease progression, treatment intolerance, or death. The primary endpoint was progression-free survival (PFS), and the secondary endpoints were objective response rate (ORR), overall survival (OS), and safety.

Results

Fifty-six patients with relapsed or refractory ES-SCLC were enrolled from January 2018 to February 2020 and 53 of them were eventually included in the evaluation population. The median follow-up was 9.8 months. At the data cut-off time (March 5, 2020), 39 patients (74%) had died and 44 (83%) had progressed. The median PFS was 3.0 months (95% CI, 2.1-3.9) and the median OS was 5.0 months (95% CI, 3.6-6.4). No complete responses were seen. Eleven patients (21%) showed a best response of partial response and 37 (70%) patients achieved stable disease. The ORR was 20.8% (11/53), and the disease control rate (DCR) was 90.6% (48/53). The 6-month OS rate was 40.1% (95% CI, 26.2-54). After 12 months, the OS rate was 18.4% (95% CI, 4.7-32.1). Possible treatment-related grade III/IV adverse events included leukopenia [8 (15.1%)], neutropenia [7 (13.2%)], anemia [4 (7.4%)], and hand-foot syndrome [2 (3.8%)]. During the study, no mortality occurred as a consequence of treatment.

Conclusions

Apatinib combined with etoposide capsules exhibits efficacy and has an acceptable safety profile. It could be used as a later-line treatment for ES-SCLC patients who have been heavily pretreated with standard therapies. Further exploration of apatinib combined with etoposide capsules in phase III trials is warranted.

Project description:The retrospective study was conducted to evaluate the efficacy and safety of careful dose modification of apatinib as third or further-line treatment in advanced gastric cancer (aGC) patients with poor performance status (PS = 2 or 3).Patients with aGC of poor PS who had received at least 2 lines of chemotherapy were treated with apatinib at a dose of 250 mg initially and best supportive care (BSC). During the whole treatment, the dose of apatinib was adjusted according to the status of PS (group treatment). Meanwhile, patients of poor PS (PS = 2 or 3) with aGC who received BSC alone after second or further-line treatment in the recent 5 years in our institution have been investigated for their median overall survival (mOS) as control. Kaplan-Meier curve was adopted for the description of OS in the 2 groups. Univariate analysis was conducted with log-rank test between OS and the potential characteristics including gender, age, PS status, primary tumor lesion, Her-2 status, and previous lines of treatment. Toxicities were assessed with the criteria of National Cancer Institute Common Toxicity Criteria (NCI CTC) version 4.0.A total of 23 patients who received apatinib plus BSC treatment and 41 patients treated with BSC alone were reviewed in the present study. Median exposure time of apatinib was 2.4 months ranging from 0.2 to 5.1 months. The median OS in the group treatment was 4.3 months (95% CI, 2.735-5.865) comparing to the control as 2.1 months (95% CI, 1.473-2.727, P = .0004). In addition, PS status was shown as the only independently significant factor to influence the OS (P = .049). Fatigue (82.6%), appetite decrease (73.9%), and anemia (69.6%) appeared to be the most common adverse events at any grade during the therapy of apatinib.The outcomes of the present study revealed that therapeutic model of careful dose modification of apatinib therapy initiated with low dose plus BSC as third or further-line treatment might be more beneficial on survival time comparing to BSC alone in patients with aGC of poor PS, however, as well as apparent adverse events.
