Candel Therapeutics, Inc. develops clinical-stage multimodal biological immunotherapies for cancer, including off-the-shelf viral immunotherapy platforms based on genetically modified adenovirus and herpes simplex virus constructs. Company news commonly covers aglatimagene besadenovec, also called aglatne or CAN-2409, in prostate cancer and non-small cell lung cancer, and linoserpaturev, or CAN-3110, from its HSV platform in recurrent high-grade glioma.
Updates also include clinical-data presentations, FDA designations or clearances, research-and-development communications, quarterly financial results, financing activity, and Nasdaq inducement grants under the company’s equity plans.
Candel Therapeutics (Nasdaq: CADL) reported systemic immune activation after aglatimagene besadenovec treatment in patients with intermediate-risk localized prostate cancer.
Early phase 2 PrTK05 blood analyses involved 13 patients receiving aglatimagene plus external beam radiation therapy and six receiving standard care alone. Cytotoxic T-cell populations expanded in the treatment arm; formal comparison with controls is ongoing. In the phase 3 PrTK03 intermediate-risk subgroup of 635 patients, treatment reduced prostate cancer recurrence or prostate cancer-specific death risk by 41% versus placebo plus radiation, with median follow-up of 58.0 months. Negative biopsies occurred in 76.6% versus 60.7% of evaluable patients, and exploratory tissue analyses showed immune changes more than two years after treatment. Candel plans a Q4 2026 FDA biologics license application, including compiled PrTK05 biodistribution and shedding data.
Candel Therapeutics (CADL) presented new phase 3 biomarker data showing sustained immune changes after aglatimagene besadenovec treatment in localized prostate cancer.
AI-enabled analysis covered 622 pre-treatment and 427 post-treatment biopsies, with post-treatment samples collected more than two years after radiation completion. Aglatimagene plus external beam radiation increased lymphocyte infiltration compared with placebo plus radiation. Paired biopsies from 108 patients with residual tumor also showed increased immune-cell infiltration and interaction with tumor cells. Previously reported negative-biopsy rates two years after treatment were 80% versus 63% for evaluable aglatimagene and control patients. Candel plans to submit a Biologics License Application.
