Apollomics Announces Vebreltinib Data at the 2024 American Society of Clinical Oncology (ASCO) Annual Meeting

Data from Phase 2 and 2/3 trials demonstrate continued efficacy and safety of vebreltinib for treating different tumor types carrying MET-driver alterations

FOSTER CITY, Calif., June 04, 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 a poster presentation and an oral presentation by partner company, Avistone Biotechnology, at the 2024 American Society of Clinical Oncology (ASCO) Annual Meeting, being held May 31-June 4, 2024, in Chicago, Ill. and virtually. Copies of the poster and oral presentation are available on the Apollomics website at ir.apollomicsinc.com/news-events/presentations.

“Vebreltinib continues to display impressive selectivity and efficacy against multiple tumor types, demonstrating its high potential to treat a range of MET-altered tumors,” said Guo-Liang Yu, PhD, Chairman and Chief Executive Officer of Apollomics. “We believe this data highlights vebreltinib as a potential agent to treat both non-small cell lung cancer (NSCLC) patients and previously treated glioblastoma (GBM) patients and we remain excited about its continued clinical development.”

The poster presentation, titled “Efficacy and safety of vebreltinib in patients with advanced NSCLC harboring MET exon 14-skipping: Results of 2.5-year follow-up in KUNPENG”, demonstrated vebreltinib consistently showed promising efficacy and favorable safety in NSCLC patients with MET exon 14-skipping mutations. Patients in cohort 1 of the Phase 2, open-label, multi-cohort study, received 200 mg of vebreltinib twice daily. The primary endpoint was overall response rate (ORR) and was assessed by blinded independent review committee (BIRC). Per BIRC assessment, the ORR was at 75%, and subgroup analyses showed the ORR was 100.0%, 66.7%, 85.7% and 100.0% among patients with any baseline brain metastases (N=5), patients with any baseline liver metastases (N=6), patients aged 75 years and older (N=21) and patients with co-occurring of MET amplification (N=12), respectively. Other efficacy parameters included disease control rate (DCR) of 96.2%, the median duration of response (DoR) of 16.5 months, the median time to response (TTR) of 1.0 month and the median progression-free survival (PFS) of 14.3 months. Furthermore, the median overall survival (OS) was 20.3 months. The 3-year OS rate was 35.1%. No new safety signals were reported with long-term vebreltinib treatment.

The oral presentation, titled “Efficacy and safety of the vebreltinib in patients with previously treated, secondary glioblastoma/IDH mutant glioblastoma with PTPRZ1-METFUsion GENe (FUGEN): A randomised, multicentre, open-label, phase 2/3 trial”, demonstrated vebreltinib data in the first completed Phase 2/3 trial of previously treated sGBM / IDH mutant glioblastoma patients with PTPRZ1-MET Fusion gene. The primary endpoint was overall survival (OS) and, after a median follow-up of 4.44 months, the median OS in the vebreltinib group and chemotherapy group were statistically significant at 6.31 months and 3.38 months, respectively. The secondary endpoints were progression-free survival (PFS) and objective response rate (ORR); the median PFS in the vebreltinib group and chemotherapy group were also statistically significant at 1.87 months and 1.05 months, respectively. No significant differences were observed in ORR (9.5% vs. 2.6%) for the vebreltinib group and chemotherapy group. Treatment-related adverse events of grade 3 or 4 were reported in 7% of the patients in the vebreltinib group, as compared with 12.2% of those in the chemotherapy group and no treatment-related deaths were observed.

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 offers a potential breakthrough for patients with MET exon 14 skipping NSCLC and other cancers driven by c-MET alterations. 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 actively assessing the potential of vebreltinib in combination with novel therapies and in a variety of tumor types in addition to developing vebreltinib as single-agent cancer therapy. 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
