Item 8.01. Other Events.
On April 10, 2024, during presentations at the American Association for Cancer Research 2024 Annual Meeting and the Annual Needham Virtual Healthcare Conference, Carisma Therapeutics Inc. (the “Company”) will provide preliminary data from the Company’s Phase 1 clinical trial of its first product candidate, CT-0508, a human epidermal growth factor receptor 2 (“HER2”) targeted chimeric antigen receptor macrophage for the treatment of HER2 overexpressing cancers, as well as preliminary data from the first three patients treated in the Company’s sub-study utilizing CT-0508 in combination with pembrolizumab. An excerpt from the presentation is attached hereto as 99.1 and is incorporated herein by reference.
The Company is providing the following data:
Based on preliminary results assessed to date from the 14 patients enrolled in group 1 and group 2 of the Company’s monotherapy treatment clinical trial, 40.7% of all target lesions had reduced in size on at least one scan across all anatomic sites.
The Company has enrolled six patients in its sub-study utilizing CT-0508 in combination with pembrolizumab. Based on preliminary results assessed to date from the first three patients treated in the sub-study, whose demographics are consistent with the 14 patients enrolled in group 1 and group 2 of the monotherapy clinical trial, the combination therapy has been generally well-tolerated after infusion with no dose-limiting toxicities. The first two of the initial three patients enrolled in the combination study were treated with corticosteroids after receiving a CT-0508 infusion and prior to pembrolizumab administration. The Company believes that systemic corticosteroids have the potential to reverse the activity of CT-0508. Based on in vitro studies, corticosteroids lead to CT-0508 cell death. The Company observed a best overall response of progressive disease in the first two patients and stable disease in the third patient per RECIST 1.1 criteria. In an individual case study presented, the third patient in the combination study, who achieved stable disease despite high baseline T-cell exhaustion, presented the greatest increase in peripheral blood T cell clonality seen to date across all seventeen patients treated to date with CT-0508 and had one out of two target lesions reduced by approximately 46%. The results from this early data are both preliminary and limited.
