Lantheus announces the first patient treated in clinical phase 2

NORTH BILLERICA, Mass., May 13, 2022 (GLOBE NEWSWIRE) — Lantheus Holdings, Inc. (“the Company”) (NASDAQ: LNTH), an established leader and fully integrated provider committed to innovative imaging diagnostics, targeted therapies and artificial intelligence solutions to detect, combat and track serious medical conditions, today announced that the first patient has received a dose in a Phase 2 trial evaluating NM-01, its proprietary SPECT imaging agent in technetium 99m used to assess PD-L1 expression in cancer cells, for its potential to identify patients who will respond to checkpoint inhibitor treatments.

The PELICAN trial (NCT04992715) is a single-arm, open-label trial in patients with non-small cell lung cancer (NSCLC). The primary endpoint is assessment of PD-L1 expression in primary tumor and metastatic lesions by NM-01 versus immunohistochemistry. Other objectives will aim to quantify the intra- and inter-tumor heterogeneity of PD-L1 expression by NM-01, as well as to establish a correlation with other diagnostic procedures. The trial is being conducted by Lantheus partner NanoMab Technology Limited (NanoMab) at King’s College London. Lantheus obtained an NM-01 license from NanoMab in 2019.

“While checkpoint inhibitor therapies targeting PD1 or PD-L1 have improved the prognosis of patients with NSCLC, these therapies often present with unpredictable patient outcomes,” said Gary Cook, MD, King’s College London. and principal investigator of the trial. “PELICAN will help us determine if NM-01 can help select responders to checkpoint inhibitor treatments, providing the right treatments to the right patients while sparing non-responders from side effects, procedures and costs. unnecessary.

Current assessment of PD-L1 expression is performed on tumor biopsy specimens by immunohistochemistry. The discrepancies in response to checkpoint inhibitor treatment highlighted potential shortcomings in the current method of assessing PD-L1 expression in a clinical setting. Immunohistochemical evaluation of tumor samples obtained by needle biopsy is often unable to capture the heterogeneity and dynamic nature of PD-L1 expression in the tumor and its microenvironment. NM-01, an imaging agent targeting PD-L1 receptors, can provide whole-body imaging assessment in a single exam and may overcome these issues and represent an alternative to multiple biopsies. NM-01 potentially allows the detection of PD-L1 expression in tumors and could be used in the management of patients before, during or after treatment with checkpoint inhibitors. NM-01 could also be used in immuno-oncology clinical trials to improve patient selection and monitor treatment response.

“The future potential of targeted imaging agents, like NM-01, to inform clinical decision-making in oncology is very exciting,” said Jean-Claude Provost, MD, interim medical director of Lantheus. “We are excited to take this important step in the development of a novel imaging agent designed to provide new insights to optimize the use of checkpoint inhibitor therapies, improve patient outcomes and to limit the need for multiple biopsies during the process. checkpoint inhibitor therapy.

“This is an important step in our development of NM-01 as a non-invasive in vivo imaging and patient screening tool for immune checkpoint drugs,” said Dr Hong Hoi. Ting, co-founder and CSO, NanoMab. “We are excited about the potential to address an unmet clinical need in oncology, and know that Lantheus, a leader in the development and commercialization of imaging agents, is the ideal partner for this program.
