Abstract Disclosures

Abstract:

Background: Abivertinib (AC0010) is a potent, selective third-generation EGFR tyrosine kinase inhibitor (TKI) that demonstrated clinical efficacy and manageable adverse events (AEs) in the phase 1 portion of the study in Chinese patients with EGFR T790M+ NSCLC. Here we report the results from patients enrolled to the phase 2 portion of the study (NCT02330367). Methods: The study enrolled locally advanced or metastatic NSCLC patients who were ≥ 18 years, progressed with the prior EGFR-TKI therapy, and must have T790M+ in tumor based on the central laboratory test. All patients received the recommended phase 2 doses of 300 mg twice daily [BID]. Results: As of March 5, 2018, 227 patients received treatment, majority of patients had adenocarcinoma (n = 220, 97%) with the median age of 59 years, 65% (n = 148) patients were female, most patients were non-smoker (n = 171, 75%), ECOG performance status of 1 (n = 162, 71%). The median treatment duration was 21 week. The treatment-related adverse events (AEs) were reported for 96.9% (n = 220) patients, mostly of grade 1 or 2 severity. The most common drug-related grade 3/4 AE (≥2%) was ALT increase (7.0%), AST increase (4.8%), diarrhea (4.4%), interstitial lung disease (4.0%), neutrophil count decrease (3.5%), and there was no drug-related grade 5 AEs. Among 209 response evaluable patients, per investigator’s assessment, 90.0% (n = 188) patients had tumor size reduction, the objective response rate (Complete Response + Partial Response [PR]) was 50.2% (n = 105; 95% CI 43.3%, 57.2%); 37.8% (n = 79) had stable disease, and the disease control rate was 88% (95% CI 82.9%, 92.1%). The median duration of response and progression-free survival estimated by Kaplan-Meier was 7.5 months (95% CI 6.0, 9.2) and was 7.5 months (95% CI 6.0, 8.8), respectively. Conclusions: Abivertinib demonstrated the clinical efficacy with manageable side-effects in patients with EGFR T790M+ NSCLC. Therefore, abivertinib could be a suitable treatment for patients with EGFR T790+ disease who have progressed on an EGFR-TKI. Clinical trial information: NCTNCT02330367.
