Ankyra Therapeutics, a biotechnology firm based in Cambridge, Massachusetts, recently announced promising preliminary data from Part 1 of its Phase 1 clinical trial involving tolododekin alfa (ANK-101), an anchored interleukin-12 (IL-12) drug conjugate. The results were presented on April 28, 2025, at the American Association for Cancer Research (AACR) Annual Meeting in Chicago, Illinois. Dr. Howard Kaufman, Ankyra’s President and CEO, highlighted the platform's ability to deliver IL-12 at much higher therapeutic doses locally to tumors without causing systemic toxicity, a significant hurdle in previous IL-12 studies. IL-12 is a cytokine known for its potent antitumor effects by enhancing the immune system's response. However, systemic administration has often led to severe adverse reactions, limiting its use in clinical settings. Ankyra’s approach involves anchoring IL-12 to aluminum hydroxide, creating ANK-101, which ensures the drug remains localized and active within the tumor microenvironment for extended periods. This method has shown promise in preclinical studies by effectively recruiting and retaining CD8+ T cells, NK cells, and M1 macrophages, thereby activating both innate and adaptive anti-tumor immunity. Dr. Joe Elassal, Ankyra’s Chief Medical Officer, emphasized the encouraging Phase 1 data, noting a sixfold increase in local IL-12 delivery compared to systemic administration, along with minimal side effects. Biomarker analysis revealed increased CD8+ T cell infiltration and PD-L1 expression in treated tumors, suggesting a robust immunological response. These findings provide a strong rationale for expanding the trial to include combination therapy with immune checkpoint inhibitors. On March 25, 2025, Ankyra reported that the first patient with advanced cutaneous squamous cell carcinoma (CSCC) had been treated with a combination of ANK-101 and Regeneron’s PD-1 inhibitor, Libtayo® (cemiplimab). This marks the beginning of the expansion cohort in the ongoing Phase 1 trial, aimed at evaluating the safety and efficacy of this combination therapy. The Phase 1 ANCHOR trial (NCT:06171750) is structured in two phases. The initial dose escalation phase assesses the safety and tolerability of ANK-101 as a monotherapy, while the subsequent expansion cohorts will explore its combination with other treatments. If successful, this approach could significantly enhance the therapeutic options for patients with advanced solid tumors, particularly those who have not responded well to conventional immunotherapies. Additional clinical trials are in the planning stages, targeting different cancer types, to further investigate the potential of ANK-101. Ankyra’s innovative technology aims to improve the therapeutic window of IL-12 by reducing systemic toxicity, thereby making this powerful cytokine more viable for cancer treatment. The company’s success with ANK-101 has also earned recognition in the media. ANK-101 will be featured in the upcoming PBS documentary series "Shelter Me" titled "The Cancer Pioneers," airing nationally on May 1, 2025. The documentary highlights groundbreaking advancements in cancer research, positioning ANK-101 as a notable breakthrough. Ankyra Therapeutics was founded in 2019 and is committed to developing novel therapies that leverage its proprietary platform. The company's goal is to create stable depots through local administration, leading to sustained immune activation and potent local and systemic immunity, all while minimizing harmful side effects. With the positive Phase 1 results, Ankyra is poised to advance its pipeline and potentially redefine the landscape of cancer immunotherapy. Industry insiders laud Ankyra’s progress, calling the Phase 1 data a significant milestone in the field of cancer immunotherapy. Experts predict that if the combination therapy proves effective in the expansion cohort, it could open new avenues for treating various types of advanced and refractory cancers. Ankyra’s focus on local drug delivery and reduced toxicity aligns well with the growing trend in personalized and precision medicine, offering hope for improved patient outcomes and quality of life. Ankyra Therapeutics is a relatively young company, but its rapid progress and innovative approach have already set it apart in the biotech sector. The presentation of positive clinical data and the media attention surrounding ANK-101 underscore the potential of this technology to make a meaningful impact in oncology.
