Lantheus Holdings, Inc. (NASDAQ: LNTH) (Lantheus), the parent company of Lantheus Medical Imaging, Inc. and Progenics Pharmaceuticals, Inc., and a global leader in the development, manufacture and commercialization of innovative diagnostic and therapeutic agents and products, announced that it has filed a Drug Master File (DMF) with the U.S. Food and Drug Administration (FDA) for NM-01, a PD-L1 imaging biomarker, and will begin making the biomarker available to academic centers and pharmaceutical companies for use in immuno-oncology (I/O) clinical trials in 2021.
NM-01 is a proprietary radiopharmaceutical biomarker using a camelid single-domain antibody and a technetium-99 radioisotope that has demonstrated a high affinity for PD-L1 protein. NM-01 could provide a specific, non-invasive approach to patient assessment, including use in whole-body imaging, or virtual biopsy. NM-01 potentially allows detection of PD-L1 expression in tumors and could be used to evaluate patients before, during, or after treatment with I/O agents, including checkpoint inhibitors, in clinical trials. The market for checkpoint inhibitors is expected to grow from $25B in 2019 to $68B in 2026.1 Lantheus licensed NM-01 from NanoMab Technology Limited in 2019 and plans to provide NM-01 as a clinical research tool, together with support and analytics, to pharmaceutical companies and the largest academic centers conducting clinical research in I/O.
“Evaluation of patients for I/O therapy is a key challenge for companies developing new therapeutics in this high-growth field,” said Etienne Montagut, Senior Vice President of Corporate Development at Lantheus. “With the filing of the DMF, Lantheus is pleased to take an important step forward in providing a novel clinical research tool with the potential to provide new information to optimize the use of I/O therapy.”
NanoMab has completed a Phase 1 study using NM-01 in 30 non-small cell lung cancer (NSCLC) patients, and preliminary data of the first 16 patients were published in the February 22, 2019 issue of Journal of Nuclear Medicine (Xing et al.). Separately, an investigator-led clinical trial involving 30 patients with either NSCLC or melanoma is in progress at King’s College London and Guy’s and St Thomas’ NHS Trust (NCT04436406); the study aims to monitor treatment response. A clinical trial authorization (CTA) was also granted by the Medicines Healthcare Products Regulatory Agency (MHRA) in November 2020 for a Phase 2 clinical study on NM-01 in NSCLC patients.
“We are very encouraged by the results of the Phase I study, which validated our innovative nanobody platform and demonstrated strong correlation with tissue-based biomarker,” said Dr. H.H. Ting, Chief Executive Officer of NanoMab. “We are pleased that leading cancer research centers are progressing with the use of NM-01 in I/O clinical trials.”
