New Preclinical Data Supports Nuvalent Lead Programs in ROS1-Positive, ALK-Positive NSCLC
Nuvalent to present at AACR-NCI-EORTC Molecular Targets Conference
CAMBRIDGE, Mass., Oct. 7, 2021 /PRNewswire/ -- Nuvalent, Inc., (Nasdaq: NUVL), a biopharmaceutical company focused on creating precisely targeted therapies for clinically proven kinase targets in cancer, provided new preclinical data on Thursday supporting advancement of its parallel lead programs in non-small cell lung cancer (NSCLC). NVL-520, a ROS1-selective inhibitor, and NVL-655, an ALK-selective inhibitor, were specifically designed to solve for the dual challenges of kinase resistance and selectivity which limit the activity and durability of currently available cancer therapies.
The data are available via three on-demand "short-talk" posters at the 2021 AACR-NCI-EORTC Virtual International Conference on Molecular Targets and Cancer Therapeutics, which runs from Oct. 7 through Oct. 10. The presentations detail additional preclinical evidence that NVL-520 and NVL-655 1) were active against both wild-type and various known resistance variants of ROS1 or ALK, respectively; 2) were brain-penetrant with the potential to address brain metastases; and 3) selectively inhibited their targets compared to the structurally related tropomyosin receptor kinase B (TRKB), thereby minimizing the potential for off-target TRKB-related central nervous system (CNS) adverse events. The posters will also be available on the Nuvalent website.
"The Nuvalent discovery team operates under an ethos of thorough investigation, with the goal of ensuring that we nominate drug candidates that best embody the product profiles we have defined in close collaboration with physician-scientists," said Henry Pelish, Ph.D., Vice President of Biology at Nuvalent and a presenting poster author. "This is exemplified in our approach to comprehensive in vitro characterization of target selectivity compared to the structurally similar kinase TRKB during the discovery and early development of both NVL-520 and NVL-655, which we detail here.
"Our physician-scientist collaborators are instrumental not only in helping us to identify the desired product characteristics that we believe are most impactful to treatment paradigms today, but also in furthering the investigation of our compounds," continued Dr. Pelish. "It has been a privilege to work closely alongside Dr. Aaron Hata's group at Mass General Cancer Center to generate the new data presented here in support of the broad preclinical activity of NVL-520 against ROS1 wild type and resistance variants. We look forward to continued collaboration as we work to advance NVL-520 and NVL-655 into clinical studies, and further mature our discovery programs."
Aaron N. Hata, M.D., Ph.D., is a Nuvalent scientific advisor and co-author whose lab at Mass General Cancer Center in Boston focuses on advancing targeted therapies for patients with lung cancer.
"Resistance mutations, off-target adverse events, and brain metastases present significant challenges in the development of the next-generation of targeted therapies for kinases such as ROS1 and ALK," said Dr. Hata. "I am encouraged by the growing body of preclinical data showing that both NVL-520 and NVL-655 maintained selective inhibition of their targets even in the presence of a wide variety of resistance mutations and displayed the important combination of both TRKB selectivity and brain penetrance to open up the potential to treat brain metastases while avoiding off-target CNS adverse events. Together, this combination of characteristics may have the potential to drive more durable responses for patients."
The U.S. Food and Drug Administration has cleared the company's Investigational New Drug application for NVL-520. Nuvalent plans to initiate the Phase 1 portion of a First-in-Human (FIH) Phase 1/2 clinical trial for NVL-520 in patients with advanced ROS1-positive NSCLC and other solid tumors in the second half of 2021. Nuvalent plans to initiate the Phase 1 portion of a FIH Phase 1/2 clinical trial investigating NVL-655 in advanced ALK-positive NSCLC and other cancers during the first half of 2022.
