Candel Therapeutics Reports Both Prolonged Median Overall Survival and Long Tail of Survival in Phase 2a Clinical Trial of CAN-2409 in Advanced Non-Small Cell Lung Cancer (NSCLC) Patients Non-Responsive to Immune Checkpoint Inhibitor (ICI) Treatment

NEEDHAM, Mass., March 26, 2025 (GLOBE NEWSWIRE) -- Candel Therapeutics, Inc. (Candel or the Company) (Nasdaq: CADL), a clinical stage biopharmaceutical company focused on developing multimodal biological immunotherapies to help patients fight cancer, today announced final survival data from a phase 2a clinical trial of CAN-2409 in patients with stage III/IV NSCLC, inadequately responding to ICI treatment. mOS was 24.5 months in 46 evaluable patients receiving 2 courses of CAN-2409 (per protocol population; cohort 1 and 2) and 21.5 months in evaluable patients from cohort 2 (n=41) that presented with progressive disease at baseline, despite ICI treatment. mOS in patients with progressive disease despite ICI treatment, was 9.8-11.8 months in other studies, including those with standard of care of docetaxel chemotherapy, which has a very poor prognosis, did not exceed 12 months in other published studies.^{(1, 2)} This final analysis included extended follow-up data (1 year after the previous data cut) with a median follow up time for the per protocol population of 32.4 months. Data showed a sizable percentage of patients with survival exceeding 24 months, evidence of a long tail of survival, with 37% of patients with progressive disease despite treatment with ICI alive 2 years after CAN-2409 administration.
