I wonder if Creatv MichroTech is still in the mix; working on potential biomarkers.
Sherlock, I was wondering the same thing. Can someone smarter than me learn anything from the following...
Creativ Bio:
CytoDyn's Phase 2 study in mCRC (NCT06699836), now underway, is enrolling 60 participants who will be tested with the LifeTracDx® blood test at multiple-time points over the course of the trial. Collected under the study protocol as an exploratory biomarker, Creatv Bio's LifeTracDx® Blood Test will be used to evaluate numeric increases in PD-L1 expression across the patient population. The study's primary endpoint is objective response rate (ORR), defined as the proportion of patients achieving a confirmed complete or partial response per RECIST v1.1, evaluating the efficacy of leronlimab in combination with trifluridine and tipiracil plus bevacizumab in patients with CCR5-positive, refractory, microsatellite-stable metastatic colorectal cancer (mCRC) over a 12-month treatment period.
LifeTracDx® uses both circulating tumor cells (CTCs) and Cancer Associated Macrophage-Like (CAML) cells, which are macrophages that engulf tumor cells, as sensitive and accurate markers for real-time monitoring of tumor response to all forms of treatment and provides pharmacokinetic changes of both CCR5 and PD-L1 from the tumor microenvironment.
and
Natera:
Under the agreement, Natera will assess CytoDyn clinical trial samples from the CLOVER Phase 2 study (ClinicalTrials.gov Identifier: NCT06699836) in patients with mCRC. SignateraTM, 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.
