Vebreltinib is efficacious in both treatment naïve and previously treated patients with NSCLC with METex14 skipping, and regardless of co-occurring MET amplification
FOSTER CITY, Calif., Sept. 16, 2024 (GLOBE NEWSWIRE) -- Apollomics Inc. (Nasdaq: APLM) (“Apollomics” or the “Company”), a late-stage clinical biopharmaceutical company developing multiple oncology drug candidates to address difficult-to-treat and treatment-resistant cancers, announced today a poster presentation at the 2024 European Society for Medical Oncology (ESMO) Congress, taking place September 13-17, 2024 in Barcelona, Spain.
“We are pleased to share the efficacy and safety data of vebreltinib showing it is efficacious in both treatment naïve and previously treated patients with non-small cell lung cancer (NSCLS) and confirmed METex14 mutation, with longer treatment follow-ups,” said Guo-Liang Yu, Ph.D., Chairman and Chief Executive Officer of Apollomics. “Interestingly, the analysis of efficacy by MET gene copy number (GCN) demonstrated that not only the majority of the patient population in the vebreltinib program does not have co-occurring MET amplification and therefore resembles the real-world patient population reported in registries, but also that vebreltinib is efficacious regardless of co-occurring METamp, achieving as high as 67% overall response rate in patients with MET GCN<4, and outperforming other MET inhibitors. The data further supports verbreltinib’s high potency and its best-in-class potential.”
The poster presentation titled “Vebreltinib Efficacy and Safety in NSCLC Patients with METex14 Skipping Mutations” highlighted data from the ongoing global Phase 2 SPARTA-II trial and the Company’s partner, Avistone, Phase 2/3 KUNPENG trial in China. The analysis of the data included 108 patients without prior exposure to MET inhibitors (72 treatment-naive and 36 previously treated NSCLC patients) that received vebreltinib, 200 mg BID in 28-day cycle, with 12 months of follow up data. With centrally confirmed METex14 skipping, overall response rate (ORR) to vebreltinib in treatment-naïve patients was 66.7% (95% CI: 54.6, 77.3) with median duration of response (DOR) of 17.3 months and median progression free survival (PFS) of 13.8 months. In the previously treated patients, ORR was 61.1% (95% CI: 43.5, 76.9) with median DOR of 16.7 months and median PFS of 7.4 months. Among the 91 vebreltinib-treated NSCLC patients with METex14 for whom GCN data was available, GCN distribution was similar to those reported in AACR project GENIE and cBioportal. The ORRs by GCN continue to support vebreltinib’s efficacy, including in the GCN<4 cohort (ORR 67.8%; n=86) - a subgroup that was reported in other MET inhibitor trials to be less responsive: 18% ORR with capmatinib in patients with METex14 NSCLC and GCN<4, and 38.6% with savolitinib in METex14 NSCLC without METamp. Similarly, ORR was 69.2% in GCN<6 (n=91) and 100% (5/5) in GCN>4 cohorts. Treatment-related adverse events (TRAE) of grade 3 or higher were reported in 48.1% of patients, with the most common being edema (16.7%). No death was reported due to TEAEs.
The poster presentation will be available on the Apollomics website under the Presentations page under the News and Events section.
About vebreltinib (APL-101)
Vebreltinib is a potent, small molecule, orally bioavailable and highly selective c-MET inhibitor. It works by inhibiting the aberrant activation of the HGF/c-MET axis, a key pathway involved in tumor growth, proliferation, and the development of resistance to certain targeted therapies such as osimertinib. By targeting c-MET dysregulation, vebreltinib has demonstrated strong tumor inhibitory effect in a variety of preclinical c-MET dysregulated human gastric, hepatic, pancreatic and lung cancer xenograft animal models and patient-derived xenograft models (PDX).
Details on the Phase 1/2 SPARTA global clinical trial can be found on clinicaltrials.gov: NCT03175224. Apollomics is developing vebreltinib as single-agent cancer therapy in a variety of tumor types and actively assessing the potential of vebreltinib in combination with novel therapies. Vebreltinib recently received conditional approval from the National Medical Products Administration (NMPA) of China and is currently under clinical investigation and not approved for any use in any other regions in the world.
