Candel Therapeutics Reports Encouraging Initial Survival Data from Phase 2 Clinical Trial of CAN-2409 in Non-Small Cell Lung Cancer
NEEDHAM, Mass., September 26, 2023 (GLOBE NEWSWIRE) — Candel Therapeutics, Inc. (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:
“We are very encouraged by the initial survival data, particularly for Cohort 2 which enrolled patients whose disease progressed despite receiving anti-PD(L)1 treatment. This patient population represents a major unmet need, since median survival following progression is typically less than 12 months with available treatments,” said Paul Peter Tak, MD, PhD, FMedSci, President and Chief Executive Officer of Candel. “Importantly, 93% of patients with long survival were low or negative for PD-L1 expression, which we believe confirms the potential of CAN-2409 to convert patients with highly immunosuppressive tumor microenvironments, unresponsive to ICI treatment, into long term survivors. These early data support the promise and potential of CAN-2409 to provide a long-term survival tail in some of the most difficult to treat NSCLC cases.”
Dr. Tak continued, “Our approach is patient-centric. The proposed treatment regimen for CAN-2409 with prodrug is approximately 12 weeks, and patients can continue their anti-PD(L)1 therapy at local treatment centers, reducing treatment burden. The immediate goal is to provide a treatment benefit through disease stabilization via the addition of CAN-2409. The ultimate goal is to extend patient survival with improved quality of life. These data support a survival benefit in individual patients, which continues to be associated with a favorable safety and tolerability profile, particularly when compared to standard of care taxane-based chemotherapy.”
“The latest biomarker research performed by Candel, PACT, CIMAC and the National Cancer Institute further supports and expands previous findings,” said Francesca Barone, MD, PhD, Chief Scientific Officer of Candel. “We demonstrated for the first time the potential of CAN-2409 to engage the humoral arm of the immune system, broadening the scope of the antitumoral immune response. The correlations between early changes in key effector immune populations after CAN-2409 treatment and survival suggest the possibility to use early biological readouts as predictors of clinical response.”
“Although ICIs have transformed initial therapy in NSCLC and extended life for many patients, there still remains a serious unmet need, especially in patients with low levels of PD-L1 expression,” said Charu Aggarwal, MD, MPH, Associate Professor for Lung Cancer Excellence, Perelman School of Medicine, University of Pennsylvania, and Co-Principal Investigator for the phase 2 clinical trial. “Most patients progress following ICI treatment and options after progression are often associated with toxicity and small treatment benefit. The report of today’s initial promising data on survival gives us an insight into the potential of CAN-2409 to produce a sustained anti-tumor immune response and potentially extend the lives of patients living with advanced NSCLC. I look forward to the maturation of these overall survival data and expected readout in Q2 2024.”
About CAN-2409
CAN-2409, Candel’s most advanced viral immunotherapy candidate, is an investigational off-the-shelf replication-defective adenovirus designed to deliver the herpes simplex virus thymidine kinase (HSV-tk) gene to a patient’s specific tumor and induce an individualized, systemic immune response against the disease. HSV-tk is an enzyme that locally converts orally administered valacyclovir into a toxic metabolite that kills nearby cancer cells. The intra-tumoral administration results in the release of tumor-specific neoantigens in the microenvironment. At the same time, the adenoviral serotype 5 capsid protein elicits a strong pro-inflammatory signal in the tumor microenvironment. This is designed to create the optimal conditions to induce an individualized and specific CD8+ T cell mediated response against the injected tumor and uninjected distant metastases for broad anti-tumor activity. Because of its versatility, CAN-2409 has the potential to treat a broad range of solid tumors. Encouraging monotherapy activity as well as combination activity with standard of care radiotherapy, surgery, chemotherapy, and ICI have previously been shown in several preclinical and clinical settings. Furthermore, more than 950 patients have been dosed with CAN-2409 with a favorable tolerability profile to date, supporting the potential for combination with other therapeutic strategies without inordinate concern of overlapping adverse events. Currently, Candel is evaluating the effects of treatment with CAN-2409 in NSCLC, borderline resectable pancreatic cancer, and localized, non-metastatic prostate cancer in ongoing clinical trials. The U.S. Food and Drug Administration granted Fast Track designation for CAN-2409 plus valacyclovir in combination with pembrolizumab in order to improve survival or delay progression in patients with stage III/IV NSCLC who are resistant to first line anti-PD(L)1 therapy and who do not have activating molecular driver mutations or have progressed on directed molecular therapy.
About Candel Therapeutics
Candel is a clinical stage biopharmaceutical company focused on developing off-the-shelf viral immunotherapies that elicit an individualized, systemic anti-tumor immune response to help patients fight cancer. Candel’s engineered viruses are designed to induce immunogenic cell death through direct viral-mediated cytotoxicity in cancer cells, thus releasing tumor neo-antigens while creating a pro-inflammatory microenvironment at the site of injection. This leads to in-situ vaccination against the injected tumor and uninjected distant metastases.
Candel has established two clinical stage viral immunotherapy platforms based on novel, genetically modified adenovirus and herpes simplex virus (HSV) gene constructs, respectively. CAN-2409 is the lead product candidate from the adenovirus platform and is currently in ongoing clinical trials in NSCLC (phase 2), pancreatic cancer (phase 2), and localized, non-metastatic prostate cancer (phase 2 and phase 3). CAN-3110 is the lead product candidate from the HSV platform and is currently in an ongoing investigator-sponsored phase 1 clinical trial in recurrent high-grade glioma. In addition,
Candel’s enLIGHTEN™ Discovery Platform is a systematic, iterative HSV-based discovery platform leveraging human biology and advanced analytics to create new viral immunotherapies for solid tumors.

About the Partnership for Accelerating Cancer Therapies
The biomarker research in the phase 2 clinical trial of CAN-2409 in NSCLC is supported by the Partnership for Accelerating Cancer Therapies (PACT), a project that supports research to identify, develop, and validate robust biomarkers ‐ standardized biological markers of disease and treatment response ‐ to advance new immunotherapy treatments that harness the immune system to attack cancer. PACT is overseen by the Foundation for the National Institutes of Health. The pharmaceutical companies participating that make funding for this project possible are: AbbVie, Amgen, Boehringer Ingelheim, Bristol‐Myers Squibb, Celgene Corporation, Genentech, Gilead, GlaxoSmithKline, Janssen/Johnson & Johnson, Novartis, and Pfizer.
