On October 26, 2022 Nykode Therapeutics ASA (OSE: NYKD), a clinical-stage biopharmaceutical company dedicated to the discovery and development of novel immunotherapies, reported the presentation of positive preliminary safety and immunogenicity results from its Phase 1/2a study of VB10.NEO, a proprietary individualized therapeutic DNA cancer vaccine, in patients with locally advanced or metastatic solid tumors (Press release, Nykode Therapeutics, OCT 26, 2022, View Source [SID1234622392]). The data will be presented today at the Neoantigen-Based Therapies Summit in Boston, Massachusetts. Nykode is developing VB10.NEO worldwide in partnership with Genentech, a member of the Roche Group.

Michael Engsig, Nykode’s Chief Executive Officer, stated: "I am thrilled with these clinical data which confirm our position at the forefront of the fully individualized cancer immunotherapy field. We believe individualized neoantigen-based immunotherapies will transform the treatment of cancer, and we are excited to continue the journey with our partners at Genentech, a global leader in immuno-oncology."
Klaus Edvardsen, Nykode’s Chief Development Officer, stated: "The data presented today show that VB10.NEO induces a broad, strong and long-lasting CD8 T cell response against patient-specific tumors, in addition to being safe and well-tolerated in combination with other anti-cancer treatments. The data continue to substantiate our differentiated platform technology and support its huge potential within individualized cancer treatments. We are happy to have such strong partners as Genentech for continued development."
Summary of Safety Results
41 patients were dosed with VB10.NEO. The data show that VB10.NEO was generally safe and well-tolerated in patients with solid tumors when administered in combination with various anti-cancer treatments. The most common adverse events reported were fatigue (34%) and diarrhea (27%). The observed adverse events are generally consistent with the known safety profiles of checkpoint inhibitors, chemotherapy, as well as other targeted cancer therapies, with no overt signs of add-on toxicity.
Summary of Immunogenicity Results
22 patients were included in the interim analysis. Blood samples were collected at baseline, week 11, 22, 34 and 54, to assess immune response to individual neoepitopes by ELISpot.
A neoantigen-specific immune response was observed in all patients (ranging from 3-20 neoepitopes)
A vaccine-induced T cell response was observed in 95% of patients, inducing expansion of both novel and pre-existing T cells
The responses were broad and the majority of the neoepitopes included in the vaccines were immunogenic
Polyfunctional Th1 CD4 and Tc1 CD8 T cell responses were observed
Ranging from 53% to 100% (or 85% on average) of the neoepitopes induced a CD8 T cell response. Cytotoxic CD8 T cells are known to be important for killing tumor cells
The breadth and magnitude of immune response increased upon multiple vaccinations
Responses to the majority of the neoepitopes were maintained for at least one year

About the Phase 1/2a Trial
VB N-01 is an open-label first-in-human Phase 1/2a study to evaluate safety, feasibility and efficacy of multiple dosing with individualized VB10.NEO or VB10.NEO and bempegaldesleukin (NKTR-214) immunotherapy in patients with locally advanced or metastatic melanoma, NSCLC, clear renal cell carcinoma, urothelial cancer or squamous cell carcinoma of head and neck, who did not reach complete responses with current standard of care immune checkpoint blockade. More information is available at clinicaltrials.gov: identifier NCT03548467.
About VB10.NEO
VB10.NEO is a proprietary individualized DNA-based neoantigen vaccine in development for the treatment of locally advanced or metastatic solid tumors under an exclusive, worldwide clinical collaboration with Genentech, a member of the Roche group. The vaccine is designed to be produced on-demand according to the neoantigen profile of an individual patient. Neoantigens are proteins generated by tumor-specific mutations not present in normal tissues and are thus an attractive target for cancer immunotherapy as they may be recognized as foreign by the immune system.
Nykode is currently conducting two clinical studies evaluating VB10.NEO: VB N-01 and VB N-02. VB N-01 is an open-label Phase 1/2a basket study to evaluate the safety and efficacy of multiple dosing with VB10.NEO in patients with locally advanced or metastatic cancer (NCT03548467). VB N-02 is an open-label Phase 1B, dose-escalation study of the safety- and antigen-specific immune responses elicited by VB10.NEO in combination with Roche’s checkpoint inhibitor atezolizumab in patients with locally advanced and metastatic tumors (NCT05018273).
