Summation
- Or the “Company”), a clinical stage biopharmaceutical company focused on discovering and developing innovative immunotherapies, will present findings today at the 8th Annual CAR-TCR Summit from its Phase 1 clinical trial of the Company’s lead product candidate, CT-0508, a human epidermal growth factor receptor 2 (“HER2”) targeted chimeric antigen receptor macrophage (“CAR-M”) for the treatment of advanced/metastatic HER2 overexpressing cancers.
- This latest data readout follows the dosing of the first patient in the ongoing sub-study of the Phase 1 clinical trial of CT-0508 in combination with pembrolizumab for the treatment of HER2 overexpressing cancers.

Carisma Therapeutics Inc. (Nasdaq: CARM) (“Carisma” or the “Company”), a clinical stage biopharmaceutical company focused on discovering and developing innovative immunotherapies, will present findings today at the 8th Annual CAR-TCR Summit from its Phase 1 clinical trial of the Company’s lead product candidate, CT-0508, a human epidermal growth factor receptor 2 (“HER2”) targeted chimeric antigen receptor macrophage (“CAR-M”) for the treatment of advanced/metastatic HER2 overexpressing cancers.
The presentation includes data from group 1 (n=9) and group 2 (n=5). Patients in both groups received the same total dose (up to 5×109 CT-0508) either via a fractionated, multi-day infusion regimen (group 1) or via a single-day bolus infusion (group 2). The data are drawn from the ongoing clinical trial led by Kim A. Reiss, MD, principal investigator of the Phase 1 clinical trial and an associate professor of Hematology-Oncology in the Perelman School of Medicine at the University of Pennsylvania.
In the presentation, Michael Klichinsky, PharmD, PhD, Co-Founder and Chief Scientific Officer at Carisma, will present data demonstrating that, in both groups, CT-0508 was successfully manufactured for patients and that the administration of CT-0508 was well-tolerated after infusion with no dose-limiting toxicities reported to date.
“As the CT-0508 trial progresses, it is promising to see consistent results supporting the safety profile, feasibility, and mechanism of action of this first-in-class CAR-M investigational therapy,” commented Dr. Klichinsky. “We look forward to results from the CT-0508 combination sub-study with pembrolizumab and continued development of CAR-M and CAR-Monocyte therapies.”
Previously, Carisma presented findings from group 1 showing that CT-0508 remodeled and activated the tumor microenvironment (“TME”) and initiated anti-tumor T cell immunity. Translational analyses combining group 1 and group 2 show that various biomarkers including metrics of TME activation, T cell activation, and HER2 status correlate with best overall response (“BOR”) of stable disease, providing further evidence of the CT-0508 mechanism of action.
The Phase 1 study translational analyses further demonstrate an increase in exhausted CD8 T cells on treatment, supporting the ongoing combination sub-study with Merck’s anti-PD1 therapy KEYTRUDA® (pembrolizumab). This latest data readout follows the dosing of the first patient in the ongoing sub-study of the Phase 1 clinical trial of CT-0508 in combination with pembrolizumab for the treatment of HER2 overexpressing cancers.
The Company is filing a Current Report on Form 8-K today with the U.S. Securities and Exchange Commission disclosing the new data from its Phase 1 clinical trial of CT-0508, including an excerpt of the presentation being made at the 8th Annual CAR-TCR Summit.
