Nuvalent Presents New Data Demonstrating Expanded Preclinical Activity with ROS1-Selective Inhibitor NVL-520 and ALK-Selective Inhibitor NVL-655 at AACR Annual Meeting 2022
Nuvalent, Inc. (Nasdaq: NUVL) presented new data at the AACR Annual Meeting 2022, highlighting the preclinical efficacy of its drug candidates, NVL-520 and NVL-655. NVL-520 showed strong activity against ROS1 fusion partners and mutations, including glioblastoma models. NVL-655 demonstrated broad preclinical activity across various ALK-driven tumors while avoiding TRKB inhibition. These findings support the ongoing Phase 1/2 studies, ARROS-1 for NVL-520 and ALKOVE-1 for NVL-655, aimed at advanced NSCLC and solid tumors, aiming for potential clinical utility.
- NVL-520 showed strong preclinical activity against diverse ROS1 fusion partners and mutations.
- NVL-655 demonstrated broad preclinical efficacy across various ALK-driven tumor types, confirming potential clinical utility.
- Both drugs show a differentiated profile compared to existing therapies, which may provide a competitive advantage in the market.
- None.
NVL-520 showed strong preclinical activity against diverse ROS1 fusion partners and kinase-domain resistance mutations, as well as in a ROS1-driven model of glioblastoma
NVL-655 demonstrated differentiation through broad preclinical activity across diverse ALK oncoproteins, resistance mutations, and tumor types while maintaining strong selectivity for ALK over TRKB
Supports broad investigation in advanced ROS1+ and ALK+ NSCLC and other solid tumors through the ongoing Phase 1/2 ARROS-1 study of NVL-520 and planned Phase 1/2 ALKOVE-1 study of NVL-655 beginning Q2 2022
CAMBRIDGE, Mass., April 8, 2022 /PRNewswire/ -- Nuvalent, Inc., (Nasdaq: NUVL) a clinical-stage biopharmaceutical company creating precisely targeted therapies for patients with cancer, today announced new data to support broad clinical exploration of its parallel lead programs NVL-520 – a ROS1-selective inhibitor – and NVL-655 – an ALK-selective inhibitor. NVL-520 and NVL-655 are central nervous system (CNS)-penetrant kinase inhibitors designed to specifically solve for the dual challenges of kinase resistance and selectivity commonly observed with currently available inhibitors.
The data are available via two posters presented at the American Association for Cancer Research (AACR) Annual Meeting 2022, which runs from April 8 through April 13. The posters will also be available on the Nuvalent website at www.nuvalent.com/news/.
"We are pleased to share new data today resulting from our continued collaborations with leading investigators in ROS1 and ALK research, which we believe further demonstrate the potential for our highly selective inhibitors to be differentiated within the dynamic treatment landscapes for non-small cell lung cancer (NSCLC) and beyond," said James Porter, Ph.D., Chief Executive Officer of Nuvalent. "These preclinical data support the inclusion of various fusion partners and resistance mutations in our ARROS-1 and ALKOVE-1 clinical trials for ROS1- and ALK-positive NSCLC, respectively, as well as the inclusion of exploratory cohorts for other advanced solid tumors outside of NSCLC."
Monika Davare, Ph.D. is an Associate Professor of Pediatrics, Division of Hematology and Oncology at Oregon Health & Science University School of Medicine and leading expert in ROS1 oncoprotein biology. Professor Davare's research is directed towards overcoming therapeutic bottlenecks in oncology, including those that arise from the lack of validated translational research models for genomic subsets of cancer.
"Translational models of ROS1-driven cancers have centered on NSCLC, where the clinical impact of fusion partners is not yet well characterized and new treatment-resistant variants continue to emerge. Hypothesizing that broad coverage of fusion partners and resistance mutations is a beneficial feature for next-generation ROS1 inhibitors, we conducted an extensive comparative analysis of NVL-520 versus currently approved as well as investigational ROS1 inhibitors," said Professor Davare. "In contrast to comparator compounds, NVL-520 exhibited consistently high potency (IC50 < 10 nM) across all models tested, and in particular displayed potencies against the recurrently problematic G2032R solvent front mutation that were ≥ 1-order of magnitude higher than all comparative agents tested."
"While models of ROS1-driven cancers outside of NSCLC are sparse, we further present data that NVL-520 induces regression in a human cell-line derived model of glioblastoma driven by a ROS1 fusion," continued Professor Davare. "This suggests potential for clinical utility outside of NSCLC and highlights the importance of developing additional research models to help accelerate the development of new therapies for genomically-driven cancers."
Luc Friboulet, Ph.D. is an investigator at Gustave Roussy focused on investigating molecular mechanisms of tumor adaptation to kinase inhibitors in solid tumors, with particular expertise in understanding resistance to ALK kinase inhibitors.
"ALK oncogenic activations as well as mutations conferring resistance to current ALK inhibitors have been characterized across a range of tumor types, suggesting that broad activity across diverse ALK-driven cancers is a beneficial feature for next-generation ALK inhibitors," said Dr. Friboulet. "In a comparative analysis of NVL-655 versus currently approved as well as investigational ALK inhibitors, NVL-655 exhibited strong activity across a wide range of fusion partners, activating mutations, and disease backgrounds, suggesting potential for broad clinical utility. Importantly, this expansive activity of NVL-655 against ALK does not come at the expense of its ability to avoid inhibition of TRKB, a limitation that has been observed with other investigational ALK inhibitors."
NVL-520 is currently under investigation in the Phase 1 portion of the Phase 1/2 ARROS-1 study (NCT05118789) for advanced ROS1-positive NSCLC and other solid tumors. Nuvalent recently announced the IND clearance for NVL-655 and plans to initiate the Phase 1 portion of the Phase 1/2 ALKOVE-1 study for advanced ALK-positive NSCLC and other solid tumors in the second quarter of 2022. In addition to these parallel lead programs, Nuvalent is advancing a robust discovery pipeline with plans to nominate two new development candidates in 2022 for ALK IXDN compound mutations and HER2 exon 20 insertions.
