Merus and Caris Life Sciences Announce Collaboration to Detect NRG1 Fusions in Cancer Patients

Merus N.V. and Caris Life Sciences announced a collaboration to detect neuregulin 1 (NRG1) fusions in cancer patients. Under the agreement, Caris has agreed to perform whole exome sequencing of DNA and whole transcriptome sequencing of RNA for certain cancer patients, focusing on pancreatic cancer, to identify the presence ofNRG1 fusions and to increase awareness of and potential enrollment in Merus’ bispecific antibody Zenocutuzumab Phase 1/2 eNRGy trial.

“We are pleased to collaborate with Merus and to identify patients with NRG1 fusions,” said David Spetzler, M.S., Ph.D., MBA, President and Chief Scientific Officer of Caris Life Sciences. “Our molecular profiling tools provide critical information physicians and patients need to make informed treatment decisions. We look forward to providing this important molecular information to clinicians, and Merus, to evaluate patient eligibility for the eNRGy trial with Zeno.”

The NRG1 gene fusion is a rare, powerful driver of cancer cell growth found in lung, pancreatic and other solid tumor types. Zeno, through its unique mechanism of blocking the interaction of the NRG1 fusion protein with its receptor HER3, has the potential to be particularly effective against NRG1+ cancers.

“We look forward to working with Caris to identify patients who may benefit from Zeno,” said Bill Lundberg, M.D., President, Chief Executive Officer and Principal Financial Officer of Merus. “While genomic sequencing is more commonly being used in the healthcare setting, it is not sufficiently employed in the diagnosis and management of pancreatic and other cancers where treatment options have been limited. We believe our collaboration with Caris will help to raise awareness of the value of molecular profiling in pancreatic and other cancers, and potentially enhance enrollment in our Zeno eNRGy trial and Early Access Program.”

Merus is currently enrolling patients on the Phase 1/2 eNRGy trial to assess the safety and anti-tumor activity of Zeno monotherapy in NRG1+ cancers. The eNRGy trial consists of three cohorts: NRG1+ pancreatic cancer; NRG1+ non-small cell lung cancer; and NRG1+ other solid tumors.
