Natera, Inc. (NASDAQ:NTRA), a global leader in cell-free DNA and precision medicine, and CytoDyn Inc. (OTCQB:CYDY) ("CytoDyn"), a clinical-stage oncology company advancing leronlimab, a first-in-class humanized monoclonal antibody targeting the CCR5 receptor with therapeutic potential across multiple indications, today announced a strategic collaboration to evaluate circulating tumor DNA (ctDNA) dynamics and generate real-world molecular insights to support CytoDyn's metastatic colorectal cancer (mCRC) development program.

Under the agreement, Natera will assess CytoDyn clinical trial samples from the CLOVER Phase 2 study (ClinicalTrials.gov Identifier: NCT06699836) in patients with mCRC. Signatera^TM, Natera's personalized assay for the detection of molecular residual disease (MRD), will be used to evaluate ctDNA dynamics and molecular response patterns associated with leronlimab treatment.

Natera will also provide customized real-world data (RWD) analyses leveraging its proprietary oncology database, which is the largest multi-timepoint early- and late-stage oncology dataset with more than 2 million plasma timepoints and enriched clinical and imaging records. By integrating molecular response data from its MRD testing platform with curated electronic medical record (EMR) data, this multimodal dataset enables analyses of patient populations, treatment patterns, ctDNA response rates, and response dynamics across diverse clinical settings. Together, these capabilities are expected to generate insights into molecular response and disease progression that may help inform future clinical development of leronlimab, including clinical trial design, biomarker-driven patient selection strategies, and broader translational research efforts.

The collaboration builds on CytoDyn's growing oncology program and follows completion of enrollment in the CLOVER study, which is evaluating leronlimab in combination with trifluridine/tipiracil (TAS-102) and bevacizumab in patients with previously treated mCRC. The collaboration is also expected to complement ongoing translational and biomarker analyses from the study aimed at further characterizing treatment response and informing future development strategies.

"Signatera has become an increasingly important tool in precision oncology and clinical development," said Jacob Lalezari, M.D., chief executive officer, CytoDyn. "Through this collaboration, we expect to gain valuable insights into ctDNA response kinetics and disease progression that may help guide future development strategies for leronlimab in colorectal cancer and potentially other solid tumor indications."

"We are pleased to partner with CytoDyn and provide their team with insights derived from one of the largest and most comprehensive real-world molecular oncology data platforms," said Matt Love, vice president, biopharma data & AI partnering, Natera. "Our platform enables biopharma partners to better understand disease biology, treatment response, and patient outcomes, helping inform key development decisions throughout the drug development lifecycle."
