On Jul. 1, 2020, Intravacc announced the signing of a strategic partnership agreement with Dutch based CimCure, focusing on cancer immunotherapies for solid tumors, for in- licensing CimCure’s iBoost technology. This agreement offered Intravacc access to this technology in developing new vaccines and for providing services involving the in-licensed technique in mutually agreed countries. This technology also enabled Intravacc to expand its translational expertise towards the development of cancer vaccines.

The iBoost (immune boost) technology was developed at Amsterdam UMC, lab-location VUMC, by Prof. Dr. Arjan Griffioen, professor of experimental oncology and CSO at CimCure. This technology overcomes limitations over current methods for inducing antibody responses against cancer specific antigens. iBoost is currently applied to elicit antibody responses against the tumor vasculature, a strategy that conquers the problem of drug resistance. This treatment strategy has a long-term efficacy and is extremely cost-effective. Proof-of-concept has been shown in several preclinical models.

By using the patented iBoost technology, Intravacc and CimCure are also involved in the joint development of a COVID-19 vaccine. CimCure/Amsterdam UMC received a 1.3 million euro grant from Health Holland, an investment organization of the Ministry of Economic Affairs. In the collaboration, CimCure will focus on the design and preclinical validation of three different types of COVID-19 vaccine concepts, while Intravacc will be responsible for the vaccine process development, the pilot production of the candidate vaccine under GMP conditions and for a phase I clinical trial.
