Helsinn presents newly available data on vepafestinib
at IASLC 2022 World Conference on Lung Cancer
Lugano, Switzerland, August 8, 2022 - Helsinn Group (“Helsinn”), a fully integrated, global biopharma company with a diversified pipeline of innovative oncology assets, announces its participation in the upcoming IASLC 2022 World Conference on Lung Cancer (WCLC) hosted by the International Association for the Study of Lung Cancer, taking place from 6-9 August in Vienna, Austria.
At the conference, new preclinical data for the investigational product vepafestinib (TAS0953/HM06), a selective RET inhibitor that has shown a distinct binding mode1 to RET and a high brain barrier permeability2, will be presented on August 9, 2022, 12:12 – 12:17 CEST.

Title: TA0953/HM06, a novel RET-specific inhibitor effective in extracranial and CNS disease models of NSCLC with RET fusions
Author: Igor Odintsov, MD
Session: MA13 – Update on ROS1 Inhibitors and New Pathways
Abstract ID: MA13.05
This Helsinn-sponsored study, which was conducted by Dr. Odintsov and colleagues in the Marc Ladanyi Lab at Memorial Sloan Kettering Cancer Center, explored the effect of vepafestinib (TAS0953/HM06), relative to other RET multi-kinase and selective inhibitors, on growth inhibition using in vitro and in vivo NSCLC extracranial and CNS disease models.
Dr. Sergio Cantoreggi, Helsinn Group Chief Scientific Officer and Head of R&D commented: “We are excited to be presenting further preclinical data on vepafestinib at the IASLC 2022 World Conference on Lung Cancer. RET alterations are a key driver in several types of cancer. The data presented on our investigational asset vepafestinib highlight Helsinn’s strong focus on targeted therapies for rare cancers and demonstrate the deployment of our fully integrated targeted therapy (FITT) strategy.”
Dr. Igor Odintsov, MD, commented: “Cancers with RET alterations have a high incidence of brain metastasis at advance stage of the disease (for example, 25% of lung adenocarcinoma patients with stage IV disease had brain metastasis)3. Developing therapies for these patients to minimize CNS progression is critically important. These preclinical results support the continued investigation and development of vepafestinib in this disease space.”

About vepafestinib (TAS0953/HM06)
Vepafestinib (also known as TAS0953/HM06 in partnership with Taiho Pharmaceutical Co., Ltd. (“Taiho”)) is an investigational, potent, orally administered, and highly selective RET inhibitor1,4. In preclinical studies, vepafestinib has shown activity against RET solvent front (G810) and gatekeeper (V804) mutations1,4. Relative to first generation selective RET inhibitors, vepafestinib is pharmacologically distinct, exhibits a distinct binding mode to RET, and has shown evidence of enhanced brain penetrability in preclinical models2. Vepafestinib is currently being evaluated in a phase 1/2 study (the margaRET study, NCT04683250) in individuals with advanced solid cancers with RET abnormalities, including those resistant to first-generation selective RET inhibitors. Taiho and Helsinn signed a co-development and commercialization agreement for TAS0953/HM06 in 2017 and will continue to pursue together all preclinical, clinical and CMC developments.
RET is a transmembrane receptor tyrosine kinase. Abnormalities in the RET gene, such as fusions and point mutations, are oncogenic drivers of multiple human cancers. RET fusions are present in 1-2 % of patients with non-small cell lung cancer (NSCLC) and are associated with a high incidence of brain metastasis at diagnosis. Patients are typically young and non-smokers. Although treatment for these patients has significantly improved in recent years, acquired resistance to first generation RET inhibitors has emerged. Overcoming this resistance and addressing the CNS progression in these patients are important areas of unmet need5,6.
