Combination apatinib and vinorelbine “may have potential” for treating patients with wild-type, advanced non–small cell lung cancer (NSCLC) who failed at least two prior lines of chemotherapy, according to researchers.
In a phase 2 trial, apatinib plus vinorelbine produced an overall response rate of 36.7% and a disease control rate of 76.7%. Nearly half of patients required dose reductions, and 17% discontinued treatment due to adverse events.
Xiangyu Zhang, MD, of Hunan Cancer Hospital in Changsha, China, and colleagues conducted this trial (NCT03652857) and detailed the results in JAMA Network Open.
The researchers noted that there is no standard treatment strategy for patients who have advanced NSCLC without actionable mutations and have failed two or more lines of chemotherapy. So the team tested apatinib plus vinorelbine in 30 such patients.
The patients’ median age was 63 years (range, 34-78 years), 60% were men, and 90% had stage IV disease. They had received a median of 2 (range, 2-5) prior lines of chemotherapy.
In this study, patients received apatinib at 500 mg once daily and vinorelbine at 60 mg/m2 once weekly. The dose of apatinib could be interrupted or reduced to manage adverse events. Patients could receive 250 mg or 500 mg on alternate days or 250 mg once daily. Patients were treated until they progressed, withdrew, or had unacceptable adverse events.
Results
Patients were treated for a median of 4 months (range, 1-22 months), and the median follow-up was 11 months (range, 4.5-14.1 months). Most patients (n = 25) continued treatment until they progressed, 17 were able to remain on the 500-mg dose of apatinib, 13 received the 250-mg dose of apatinib, and 5 patients discontinued treatment due to adverse events.
The overall response rate was 36.7%, and the disease control rate, defined as the proportion of patients with complete response, partial response, and stable disease, was 76.7%. There were no complete responses, 11 partial responses, 12 patients with stable disease, and 7 patients who progressed. Rates of response, disease control, and progression were similar whether patients received the 500-mg dose of apatinib or the 250-mg dose.
The median progression-free survival was 4.5 months, and the median overall survival was 10 months.
Hand-foot syndrome was the most common adverse event, with grade 1-2 hand-foot syndrome occurring in 13 patients (43%), grade 3 occurring in 5 patients (17%), and grade 4 occurring in 1 patient (3%).
The adverse events that led to treatment discontinuation were grade 3 weakness (n = 1), pleural effusion (n = 1), fungal infection (n = 1), and grade 3 hand-foot syndrome (n = 2). There were no fatal adverse events.
“” the researchers concluded. “Further evaluation of this combination in phase 3 trials is warranted.”
The current study was funded by grants from the National Natural Science Foundation of China and the Hunan Natural Science Foundation. The researchers disclosed no conflicts of interest.
