LNP formulation

Our innovative proprietary LNP platforms are tailored for specific routes of administration, intravenous (IV), intra-tumoral (IT) and intramuscular (IM), allowing better targeted biodistribution. Studies have demonstrated substantial mRNA payload distribution to target tissue.

mRNA chemistry

Our proprietary mRNA chemistry platform technology enable sequence engineering of mRNA constructs to ensure optimal mRNA translation efficiency and maximal mRNA stability. Sequence engineering can be tuned to enable immune silent or immune-stimulatory mRNA, in addition, constructs can be optimized for improved tissue specific expression.
