Carisma Announces Latest Data from Phase 1 Clinical Trial of CT-0508 at 8th Annual CAR-TCR Summit

 

Group 2 data available to date support primary safety and feasibility endpoints of single-day bolus dosing of CT-0508

 

New translational analyses combining group 1 & group 2 continue to support CAR-M mechanism of action, demonstrating a correlation between biomarkers and best overall response

 

PHILADELPHIA, PA – September 1, 2023 – 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 5x109 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.

About CT-0508

 

CT-0508 is a human epidermal growth factor receptor 2 (HER2) targeted chimeric antigen receptor macrophage (CAR-M). It is being evaluated in a landmark Phase 1 multi-center clinical trial that focuses on patients with recurrent or metastatic HER2-overexpressing solid tumors whose cancers do not have approved HER2-targeted therapies or who do not respond to treatment. Carisma is selecting participants who have tumors of any anatomical origin, but with the commonality of overexpressing the HER2 receptor on the cell surface, which is the target for our CAR-M. The Phase 1 clinical trial marks the first time that engineered macrophages are being studied in humans. The trial continues to enroll patients at seven clinical sites in the U.S., including (i) Penn Medicine’s Abramson Cancer Center, (ii) the University of North Carolina Lineberger Comprehensive Cancer Center, (iii) the City of Hope National Medical Center, (iv) the MD Anderson Cancer Center, (v) the Sarah Cannon Cancer Research Institute, (vi) Oregon Health & Science University and (vii) Fred Hutchinson Cancer Center.
