(Candel or the Company) (Nasdaq: CADL), a clinical stage biopharmaceutical company focused on developing viral immunotherapies to help patients fight cancer, today announced updated activity data from its ongoing, open-label, phase 2 clinical trial of CAN-2409 plus valacyclovir in combination with continued immune checkpoint inhibitor (ICI) treatment in patients with non-resectable, stage III/IV non-small cell lung cancer (NSCLC), who have an inadequate response to front line anti-PD(L)1 therapy. These patients historically have had an expected median overall survival of 10-13 months (Reckamp K et al. J Clin Onc 2022;40:2295-2306). The aim of the CAN-2409 immunotherapy antitumor strategy is to raise the tail on the survival curve by increasing the number of long survivors beyond 10-13 months. In 2022, the Company presented data from this phase 2 clinical trial where patients who received two administrations of CAN-2409 plus prodrug demonstrated: 1) increased infiltration of CD8+ cytotoxic T cells in the tumor microenvironment, systemic expansion of effector T cells and increased soluble granzyme B levels in peripheral blood, 2) favorable changes in the trajectory of tumor progression, 3) decreased tumor size of target lesions in most patients, and 4) reduced size of uninjected tumor lesions (Aggarwal C et al. Abstract #9037 ASCO June 2022 and Aggarwal C et al. Candel Virtual R&D Day, December 2022). These data were further confirmed in the current update. Highlights as of August 1, 2023 data cutoff, include: As of data cutoff (August 1, 2023), 40 patients across Cohort 1 (stable disease at enrollment; n=5) and Cohort 2 (progressive disease at enrollment; n=35) were evaluable, as they received two courses of CAN-2409 + valacyclovir and completed the 12-week treatment window.While overall survival is not yet mature, Candel has observed an encouraging number of long survivors, which the Company believes that CAN-2409 may indu...
