NEEDHAM, Mass., April 25, 2024 (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 that two abstracts were accepted for presentation at the 2024 American Society of Clinical Oncology (ASCO) Annual Meeting taking place May 31 to June 4, 2024, in Chicago, IL. The first presentation will feature data from the ongoing phase 1 clinical trial of CAN-3110 in patients with recurrent high-grade glioma. The presentation will focus on patients recruited in cohort C, treated with multiple injections of CAN-3110 (up to six), demonstrating that this approach is both feasible and well tolerated. The second presentation will show topline overall survival data from the 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.

Details are as follows:

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 tumor and induce an individualized, systemic anti-tumor immune response. HSV-tk is an enzyme that locally converts orally administered valacyclovir into a toxic metabolite that kills nearby cancer cells, resulting in the release of a wide variety of cancer antigens. At the same time, the adenoviral serotype 5 capsid protein has the potential to elicit a pro-inflammatory response in the tumor microenvironment. 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. As a result, CAN-2409 is an off-the-shelf drug candidate designed to result in an individualized anti-tumor immune response with the potential to treat a broad range of solid tumors. Encouraging monotherapy activity, as well as combination therapy activity with Standard of Care (SoC) radiotherapy, surgery, chemotherapy, and ICI, have previously been shown in several preclinical and clinical settings. Furthermore, to date, more than 1,000 patients have been dosed with CAN-2409 with a favorable tolerability profile 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 ductal adenocarcinoma (PDAC), and localized, non-metastatic prostate cancer. CAN-2409 has been granted Fast Track Designation by the U.S. Food and Drug Administration (FDA) for 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 treatment of localized, primary prostate cancer in combination with radiotherapy to improve the local control rate, decrease recurrence and improve disease-free survival. Candel’s pivotal phase 3 clinical trial in prostate cancer is being conducted under a Special Protocol Assessment by FDA. The FDA has also granted Orphan Drug Designation to CAN-2409 for the treatment of PDAC.

About CAN-3110

CAN-3110 is a first-in-class, replication-competent herpes simplex virus-1 (HSV-1) oncolytic viral immunotherapy candidate designed with dual activity for oncolysis and immune activation in a single therapeutic. Its activity is designed to be conditional to the expression of Nestin in cancer cells. CAN-3110 is being evaluated in a phase 1b clinical trial in patients with recurrent HGG (rHGG). In October 2023, the Company announced that Nature published results from this ongoing clinical trial. CAN-3110 was well tolerated with no dose-limiting toxicity reported and CAN-3110 plus prodrug was associated with improved survival. Positive HSV-1 serology was a predictor of response and was associated with improved survival. Increased infiltrating immune cells in the tumor microenvironment and expansion of the T cell repertoire after treatment were also associated with improved survival. In the clinical trial, the investigators observed a nearly doubling of the expected median overall survival after a single CAN-3110 injection compared to historical reports of less than 6 to 9 months in this therapy-resistant condition. By comparison, survival in the anti-HSV1 positive patients treated with CAN-3110 was more than 14 months. The Company and academic collaborators are currently evaluating the effects of multiple CAN-3110 injections in rHGG, supported by the Break Through Cancer Foundation.
