Nuvalent Announces New Preclinical Data for Selective Kinase Inhibitors NVL-330 and NVL-655
Nuvalent, Inc. (Nasdaq: NUVL) announced new preclinical data for its selective kinase inhibitors NVL-330 and NVL-655 at the 34th EORTC-NCI-AACR symposium. NVL-330 targets HER2 exon 20 insertion mutations and demonstrates selectivity over wild-type EGFR, along with potential for treating brain metastases. Preclinical results indicate NVL-655's activity in ALK-positive tumors, overcoming resistance mutations. Nuvalent continues to advance its pipeline, showcasing significant therapeutic potential against hard-to-treat cancers.
- NVL-330 shows selectivity for HER2 exon 20 mutations over wild-type EGFR, reducing treatment-limiting side effects.
- Preclinical results indicate NVL-655's broad activity against ALK mutations, including resistance variants.
- Both candidates are brain-penetrant, addressing critical needs for treating tumors with brain metastases.
- None.
Preclinical data demonstrated that NVL-330 inhibits HER2 exon 20 insertion mutations, is selective for HER2 versus wild-type EGFR, and is brain-penetrant
NVL-655 preclinical data further support its best-in-class potential for patients with advanced ALK-positive NSCLC and other solid tumors
Data Presented at the 34th EORTC-NCI-AACR (ENA) Symposium
CAMBRIDGE, Mass., Oct. 26, 2022 /PRNewswire/ -- Nuvalent, Inc. (Nasdaq: NUVL), a clinical-stage biopharmaceutical company focused on creating precisely targeted therapies for clinically proven kinase targets in cancer, today announced the presentation of new preclinical data for NVL-330, its recently nominated HER2-selective inhibitor, and NVL-655, its ALK-selective inhibitor currently under investigation in the ALKOVE-1 Phase 1/2 study for advanced ALK-positive non-small cell lung cancer (NSCLC) and other solid tumors.
The two posters will be presented at the EORTC-NCI-AACR (ENA) 2022 symposium taking place October 26-28, 2022 in Barcelona, Spain. The posters will also be available on the Nuvalent website.
"We believe the new preclinical data for NVL-330 and NVL-655 continue to support Nuvalent's foundational approach to the discovery of therapeutics which aim to solve for multiple, and sometimes competing, challenges in structure-based drug design," said Henry Pelish, Ph.D., Vice President of Drug Discovery at Nuvalent. "This first presentation of NVL-330's preclinical profile demonstrates the target characteristics set out for this program to address medical needs identified in collaboration with leading physician-scientists, including activity against tumors driven by HER2 exon 20 insertion mutations, selectivity for HER2 versus wild-type EGFR, and brain penetrance."
Preliminary data from the Phase 1 portion of the ARROS-1 study of Nuvalent's parallel lead program, NVL-520, will also be presented at the "New Drugs on the Horizon" oral plenary session on October 28, 2022.
"In our view, these NVL-330 and NVL-655 presentations, along with our NVL-520 clinical data presentation later this week, embody the rapid progress and growth we continue to achieve across our pipeline," said James Porter, Ph.D., Chief Executive Officer at Nuvalent. "NVL-330, our third novel drug candidate since company creation four years ago, is not only an exciting addition to our portfolio of selective kinase inhibitors but also a testament to our team's continued ability to advance novel discovery programs while executing in parallel against our development goals."

NVL-330 is a novel, brain-penetrant HER2-selective tyrosine kinase inhibitor targeting HER2 exon 20 insertion mutations (HER2ex20). It was specifically designed with the aim to address the combined medical need of treating tumors driven by HER2ex20, avoiding treatment-limiting adverse events due to off-target inhibition of wild-type EGFR, and treating brain metastases. HER2ex20 are oncogenic driver mutations in an estimated 1
The data presented at ENA represent the first characterization of this new development candidate. Preclinical data demonstrated that NVL-330 potently inhibited HER2ex20 in cell-based assays and was highly selective for HER2ex20 over the structurally related wild-type EGFR. This selectivity is a critical aspect of NVL-330's design given that inhibition of wild-type EGFR is associated with dose-limiting side effects including skin rash and gastrointestinal toxicity.
In addition, the demonstrated preclinical brain penetrance and intracranial activity of NVL-330 suggests the potential for treating or preventing brain metastases. Brain metastases are present at diagnosis in an estimated
Title: Preclinical activity of NVL-655 in patient-derived models of ALK cancers, including those with lorlatinib-resistant G1202R/L1196M compound mutation

NVL-655 is a brain penetrant, ALK-selective inhibitor with potent activity observed in preclinical studies across diverse tumor types, ALK alterations, and single and compound resistance mutation variants - some of which confer resistance to all other approved ALK kinase inhibitors.
This poster presentation adds to the growing body of data demonstrating NVL-655's well characterized preclinical profile. It includes new preclinical data in additional patient-derived models harboring single and compound ALK resistance mutations. Notably, NVL-655 induced regression in an in vivo model derived from a patient with ALK fusion-positive NSCLC harboring G1202R/L1196M compound mutation after disease progression on sequential crizotinib, alectinib and lorlatinib treatment. Among all inhibitors tested, we observed that NVL-655 showed the broadest preclinical activity across ALK fusion partners and resistance mutations while maintaining a wide selectivity window over TRKB.
Clinical investigation of NVL-655 is currently ongoing in the Phase 1 portion of the ALKOVE-1 Phase 1/2 study of NVL-655 for patients with advanced ALK-positive NSCLC and other solid tumors.
NVL-330 is a novel, brain-penetrant HER2-selective tyrosine kinase inhibitor targeting HER2 exon 20 insertion mutations (HER2ex20). It was specifically designed to address the combined medical need of treating tumors driven by HER2ex20 mutations, avoiding treatment-limiting adverse events due to off-target inhibition of wild-type EGFR, and treating brain metastases.
NVL-655 is a novel brain-penetrant ALK-selective inhibitor created to overcome limitations observed with currently available ALK inhibitors. NVL-655 is designed to remain active in tumors that have developed resistance to first-, second-, and third-generation ALK inhibitors, including tumors with the solvent front G1202R mutation or compound mutations G1202R / L1196M ("GRLM"), G1202R / G1269A ("GRGA"), or G1202R/L1198F ("GRLF"). NVL-655 has been designed for CNS penetrance to improve treatment options for patients with brain metastases. NVL-655 has been observed in preclinical studies to selectively inhibit wild-type ALK and its resistance variants over the structurally related tropomyosin receptor kinase (TRK) family to potentially avoid TRK-related CNS adverse events seen with dual TRK/ALK inhibitors and drive more durable responses for patients. NVL-655 is currently being investigated in the ALKOVE-1 study (NCT05384626), a first-in-human Phase ½ clinical trial for patients with advanced ALK-positive non-small cell lung cancer (NSCLC) and other solid tumors.
