CimCure's Approach

CimCure develops cancer vaccines through its proprietary Immune-Boost (iBoost) technology of targeted conjugate vaccines. 

CimCure has identified specific targets in the tumor vasculature. By direct targeting and destruction of endothelial cells in the tumor blood vessels efficient prevention of tumor growth can be achieved.

Angiogenesis inhibition​​

Angiogenesis is the formation of new blood vessels. Prevention of blood vessel growth will lead to inhibition of cancer growth. This is an attractive approach for treatment of cancer.  However, past and current angiostatic drugs are known for rapid induction of drug resistance and loss of effectiveness. This is due to intervention in tumor-produced growth factors or their receptors. 

CimCure’s approach directly targets the tumor blood vessels. This attenuates tumor growth directly. An additional advantage of targeting blood vessels is that the barrier function of the tumor vasculature for leukocytes can be lifted (huinen et al, Nature Reviews Clinical Oncology, 2021).

This way long-term efficacy of CImCure’s vaccines is seen.

Vascular targeting by iBoost​

By vaccination with the target protein, conjugated to a proprietary engineered bacterial iBoost sequence, high levels of antibodies can be induced against the target protein.   

iBoost has shown proof-of-concept in preclinical studies in colon cancer, melanoma and glioblastoma, as well as in an efficacy study in client-owned dogs with spontaneous bladder cancer. 

CimCure’s cancer vaccines are efficient and safe, widely applicable, fast and highly cost-effective.
