Lantheus Announces First Patient Dosed in Phase 2 Clinical Trial of NM-01 to Monitor PD-L1 Expression in Non-Small Cell Lung Cancer Patients
Lantheus Holdings, Inc. recently announced the first patient has been dosed in a Phase 2 trial evaluating NM-01, its proprietary technetium 99m SPECT imaging agent used to assess PD-L1 expression in cancer cells, for its potential to identify patients who will respond to checkpoint inhibitor therapies.
The PELICAN trial (NCT04992715) is an open-label, single-arm trial in non-small cell lung cancer (NSCLC) patients. The primary endpoint is the assessment of PD-L1 expression in primary tumor and metastatic lesions by NM-01 compared to immunohistochemistry. Other objectives will look at quantifying intra- and inter-tumoral heterogeneity of PD-L1 expression by NM-01, as well as establishing correlation with other diagnostic procedures. The trial is being conducted by Lantheus’ partner NanoMab Technology Limited (NanoMab) at King’s College London. Lantheus licensed NM-01 from NanoMab in 2019.
“While checkpoint inhibitor therapies targeting PD1 or PD-L1 have improved the prognosis for NSCLC patients, there are often unpredictable outcomes with these therapies for patients,” said Gary Cook, MD, King’s College London, and principal investigator of the trial. “PELICAN will help us determine if NM-01 can aid in selecting responders to checkpoint inhibitor therapies, thereby getting the right treatments to the right patients while sparing non-responders from unnecessary side-effects, procedures and costs.”
Current assessment of PD-L1 expression is performed on tumor biopsy samples using immunohistochemistry. Discrepancies in checkpoint inhibitor treatment response have highlighted potential deficiencies in the current method of evaluating PD-L1 expression in a clinical setting. Immunohistochemical assessment of tumor samples obtained by needle biopsy is often unable to capture the heterogeneity and dynamic nature of PD-L1 expression within the tumor and its microenvironment. NM-01, an imaging agent targeting PD-L1 receptors, can provide whole-body imaging assessment in a single examination and could overcome these issues and represent an alternative to multiple biopsies. NM-01 potentially allows 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 immune-oncology clinical trials to improve patient selection and monitor response to therapy.
“The future potential for targeted imaging agents, like NM-01, to inform clinical decision-making in oncology is very exciting,” said Jean-Claude Provost, MD, Interim Chief Medical Officer, Lantheus. “We are pleased to take this important step forward in the development of a novel imaging agent that is designed to provide new information to optimize the use of checkpoint inhibitor therapies, improve patient outcomes and limit the need for multiple biopsies to be performed over the course of checkpoint inhibitor treatment.”
“This is an important step forward in our development of NM-01 as a non-invasive in vivo imaging and patient selection 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 right partner for this program.”
