- New preclinical data on the second drug candidate from the enLIGHTEN™ Discovery Platform expected by Q3 2024
- Phase 1 data for CAN-3110 in recurrent high-grade glioma expected in 2H 2024 for the multiple injection cohort
- Phase 2 topline data for CAN-2409 in low-to-intermediate-risk, localized, non-metastatic prostate cancer expected in Q4 2024
- Phase 3 topline data for CAN-2409 in localized intermediate/high-risk prostate cancer expected in Q4 2024
These milestones present a compelling opportunity for progress, success and significant differentiation, underscoring the Company's dedication to advancing its therapeutic pipeline.
2023 Accomplishments:
- Phase 2 clinical trial of CAN-2409 in NSCLC
- In September 2023, the Company announced encouraging initial activity and biomarker data from the phase 2 clinical trial of CAN-2409 in NSCLC. Initial data suggests that ongoing survival is consistent with an increased tail on the maturing survival curve. Negative or low PD-L1 status appears to be associated with long survival in CAN-2409 treated patients. Biomarker data suggests an association between immune cell activation after the second injection of CAN-2409 and subsequent survival.
- U.S. Food and Drug Administration (FDA) granted Fast Track Designation for CAN-2409 plus valacyclovir in combination with pembrolizumab to improve survival or delay progression in patients with Stage III (not candidates for curative intent) or Stage IV non-small cell lung cancer, 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.
- Phase 2 clinical trial of CAN-2409 in non-metastatic pancreatic cancer
- In November 2023, the Company reported initial positive interim clinical activity and biomarker data from a randomized, controlled clinical trial where a notable increase in survival was observed in patients with borderline resectable pancreatic ductal adenocarcinoma (PDAC) after experimental treatment with CAN-2409. Estimated OS rate at 36 months was 71.4% in patients treated with CAN-2409 plus standard of care chemoradiation followed by resection versus 16.7% in the control arm treated with standard of care chemoradiation followed by resection. In patients with progressive disease, there was both a CA19-9 and a survival response to salvage chemotherapy in the CAN-2409 arm, but not in the control arm. Safety analysis demonstrated that multiple injections of CAN-2409 were generally well tolerated, with no reported dose-limiting toxicities and no reported cases of pancreatitis.
- FDA granted Fast Track Designation for CAN-2409 plus prodrug (valacyclovir) for the treatment of patients with pancreatic ductal adenocarcinoma to improve overall survival.
- Phase 1 clinical trial of CAN-3110 in high-grade glioma
- In October 2023, Candel published results in Nature demonstrating that CAN-3110 was well tolerated with no dose-limiting toxicity reported. The investigators observed a nearly doubling of the expected median (mOS) after a single CAN-3110 injection, achieving a median OS of 12 months, compared to historical reports of less than 6 to 9 months in this therapy-resistant condition. Positive HSV-1 serology was a predictor of response and was associated with improved survival (mOS in this population reached 14 months). Increased infiltrating immune cells in the tumor microenvironment and expansion of the T cell repertoire after treatment were also associated with improved survival, demonstrating the ability of CAN-3110 to elicit both a local and systemic antitumoral response.
- enLIGHTEN™ Discovery Platform
- During the Society for Immunotherapy of Cancer (SITC) 2023 Annual Meeting and the International Oncolytic Virus Conference in November 2023, Candel presented preclinical data from the first experimental candidate from its discovery pipeline: Alpha 201-macro-1, an investigational, locally delivered biological oncolytic therapeutic, designed to interfere with the CD47/SIRP1a pathway, which demonstrated better inhibition of tumor growth when compared to systemic anti-CD47 antibody therapy in a mouse model of breast cancer.
Advancing the Immunotherapy Field
The Company is poised to advance the next generation of viral immunotherapy, leveraging a data-driven approach to create new assets by design and advance development of existing drug candidates, creating new value inflection points.
“The data generated with CAN-3110 in recurrent high-grade glioma represents a significant step forward in the development of groundbreaking therapeutic candidates for this difficult to treat disease,” said Francesca Barone, M.D. PhD, CSO, at Candel Therapeutics. “At the same time, they provide initial proof of concept for the expansion of CAN-3110 in other Nestin positive indications. With the enLIGHTEN Discovery Platform, we are leveraging our internal capabilities in advanced analytics, cancer biology and vectorology to design a new class of multimodal therapeutics that are able to overcome mechanisms of resistance present in the tumor microenvironment. This platform is open for collaborations with external partners.”
Operational Excellence and Efficiency:
- The Company's strategic prioritization of programs highlights Candel Therapeutics' commitment to operational excellence and efficiency. This focus has translated into an extension of Candel runaway, while providing the opportunity to generate preclinical data in support of the expansion of CAN-3110 in novel indications, to develop enLIGHTEN for external partnerships, and deliver on the readouts of Candel’s advanced clinical trials.
- This approach positions the Company for sustained success in the current dynamic market for new cancer therapeutics.
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 disease. 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. 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 Company plans to explore the right partnering opportunities for the future development of this asset.
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 conditional to the expression of Nestin in cancer cells. CAN-3110 is being evaluated in a phase 1 investigator-sponsored clinical trial in patients with recurrent HGG. In October 2023, the Company announced that Nature published results from this 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 recurrent HGG, supported by the Break Through Cancer Foundation, and expect initial results in H2 2024.
Candel will also initiate IND-enabling work in a second indication characterized by Nestin expression.
About the enLIGHTEN™ Discovery Platform
The enLIGHTEN™ Discovery Platform is a systematic, iterative herpes simplex virus (HSV)-based discovery platform leveraging human biology and advanced analytics to create new multimodal biological immunotherapies for solid tumors. In October 2022, the Company announced a discovery collaboration with the University of Pennsylvania Center for Cellular Immunotherapies to identify how viral immunotherapy could enhance the efficacy of CAR-T cell therapy in solid tumors. The enLIGHTEN™ Discovery Platform is designed to deconvolute the complexity of the tumor microenvironment to identify druggable properties that correlate with clinical outcomes. These discoveries are rapidly translated into optimized multi-gene payloads of tumor modulators that are tailored for specific indications, disease stage, and rationally designed therapeutic combinations. During the Society for Immunotherapy of Cancer (SITC) 2023 Annual Meeting and the International Oncolytic Virus Conference in November 2023, Candel presented encouraging data on the discovery pipeline, demonstrating the effects of Alpha 201-macro-1, an investigational locally delivered biological oncolytic therapeutic designed to interfere with the CD47/SIRP1a pathway, in a mouse model of breast cancer.
