LifeTracDx® Blood Test to be Performed in Key Colorectal Clinical Trial

MONMOUTH JUNCTION, N.J., March 27, 2025 /PRNewswire/ — Creatv Bio, a Division of Creatv MicroTech, Inc. (Creatv) will be collaborating with CytoDyn Therapeutics Corporation (CytoDyn) to assess patient response to their drug using the LifeTracDx^® blood test.

CytoDyn has received FDA clearance to initiate a Phase II study of leronlimab in patients with relapsed or refractory micro-satellite stable colorectal cancer (CRC) (NCT06699835). The drug, leronlimab, targets CCR5 marker on the tumor.

Creatv will perform the LifeTracDx^® liquid biopsy in a number of CytoDyn studies including NCT06699835. The LifeTracDx^® test is based on analyzing two biomarkers: (1) circulating tumor cells (CTCs) and (2) Cancer Associated Macrophage-Like (CAML) cells, which are macrophages that engulf tumor cells. Both CTCs and CAMLs contain tumor material.

By tracking CTC and CAML counts, and CAML size at various time points, LifeTracDx® can provide prognostic insights and predict treatment response. CytoDyn is also interested in the expressions of CCR5 and PD-L1 markers on the tumor. These markers can change over time. LifeTracDx^® can provide this information by a blood test – no tissue is required. The LifeTracDx^® assay will help CytoDyn to better evaluate the effectiveness of their drug.
