Candel Therapeutics Reports Prolonged Overall Survival in Phase 2 Clinical Trial of CAN-2409 for Advanced Non-Small Cell Lung Cancer (NSCLC) in Patients Non-Responsive to Immune Checkpoint Inhibitor (ICI) Treatment at 2024 ASCO Annual Meeting
NEEDHAM, Mass., May 23, 2024 – 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 topline overall survival data from its phase 2 clinical trial of CAN-2409, a multimodal biological immunotherapy candidate, plus valacyclovir (prodrug), together with standard of care (SoC) immune checkpoint inhibitor (ICI) therapy in patients with Stage III/IV non-small cell lung cancer (NSCLC) inadequately responding to ICI (anti-PD-(L)1) therapy. The data will be presented at the 2024 American Society of Clinical Oncology (ASCO) Annual Meeting, to be held in Chicago, May 31 to June 4, 2024, by Charu Aggarwal, MD, MPH, FASCO, Leslye M. Heisler Associate Professor for Lung Cancer Excellence at the Perelman School of Medicine, University of Pennsylvania and Co-Principal Investigator of the clinical trial.
Highlights of the presentation include: 1) median overall survival (mOS) of 20.6 months achieved in patients with progressive disease despite ICI treatment after two administrations of CAN-2409 plus prodrug; for context, in a 2022 publication of a clinical trial in a similar patient population, mOS in the control arm that received SoC docetaxel-based chemotherapy was 11.6 months; improved survival was observed across both PD-(L)1 positive and PD-(L)1 negative tumors; 2) beneficial effect on both
injected and uninjected tumors in more than 70% of the patients with metastatic disease and at least one uninjected tumor; and 3) a significant increase in circulating CD8+ cytotoxic and CD4+ effector and central memory T cells and increased soluble granzyme B levels in peripheral blood after the second (‘booster’) injection of CAN-2409, associated with subsequent prolonged survival (in each case, as of an April 1 data cut-off). Together, these data continue to support the emerging differentiated profile of CAN-2409 in this difficult-to-treat condition.
“The results from our phase 2 trial in NSCLC continue to support the tremendous promise of CAN-2409 across multiple solid tumors. We are particularly encouraged by the overall survival observed in the patients whose disease had progressed despite receiving prior anti-PD-(L)1 treatment. Improved overall survival is, ultimately, what matters to patients and to the regulators,” said Paul Peter Tak, MD, PhD, FMedSci, President and Chief Executive Officer of Candel. “These results, together with our recently reported overall survival data in a randomized clinical trial in pancreatic cancer, add to the growing body of evidence supporting the notion that CAN-2409 treatment may convert progressive cancer into stable disease associated with survival benefit in advanced cancers with high unmet medical needs.”
Previously, the Company received FDA Fast Track Designation for CAN-2409 in NSCLC and pancreatic cancer as well as orphan drug designation in pancreatic cancer.
“Current therapeutic options for advanced NSCLC patients whose disease progresses despite ICI treatment are limited; they are characterized by poor tolerability and limited clinical benefit,” said Charu Aggarwal, MD, MPH, FASCO. “The data reported today suggest that CAN-2409 can reactivate these patients’ exhausted immune systems, including those with low PD-(L)1 expression. This systemic anti-tumor immune response translated to a durable response; increased numbers of circulating cytotoxic and memory T cells were associated with subsequent prolonged survival. I look forward to the continued development of CAN-2409 in NSCLC as a promising approach in an area of unmet therapeutic need.”

existing care for patients with NSCLC. As of April 1, 2024, there were no dose-limiting toxicities or grade 4 or higher treatment-related adverse events (TRAEs); the majority of TRAEs were grade 1 or 2, and there were three grade 3 TRAEs (one pyrexia, two pneumonitis).

About CAN-2409
CAN-2409, Candel’s most advanced multimodal biological 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 tumor. HSV-tk is an enzyme that locally converts orally administered valacyclovir into a toxic metabolite that kills nearby cancer cells. Together, this regimen is designed to induce an individualized and specific CD8+ T cell-mediated response against the injected tumor and uninjected distant metastases for broad anti-tumor activity, based on in situ vaccination against a variety of tumor antigens. 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 immune checkpoint inhibitors have previously been shown in several preclinical and clinical settings. More than 1,000 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 CAN-2409 in NSCLC, borderline resectable PDAC, and localized, non-metastatic prostate cancer in ongoing clinical trials. CAN-2409 plus prodrug (valacyclovir) has been granted Fast Track Designation by the U.S. Food and Drug Administration (FDA) for the treatment of PDAC, stage III/IV NSCLC in patients who are resistant to first line PD-(L)1 inhibitor therapy and who do not have activating molecular driver mutations or have progressed on directed molecular therapy, and localized primary prostate cancer. Candel’s pivotal phase 3 clinical trial in prostate cancer is being conducted under a Special Protocol Assessment with the FDA. The FDA has also granted Orphan Drug Designation to CAN-2409 for the treatment of PDAC.
About Candel Therapeutics
Candel is a clinical stage biopharmaceutical company focused on developing off-the-shelf multimodal biological immunotherapies that elicit an individualized, systemic anti-tumor immune response to help patients fight cancer. Candel has established two clinical stage multimodal biological 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 non-small cell lung cancer (NSCLC) (phase 2), borderline resectable PDAC (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 phase 1b clinical trial in recurrent high-grade glioma (rHGG). Finally, 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.
