Cell and gene therapies, as well as viral vaccines, need higher production yields—and thats where we excel. We significantly increase yields by targeting the innate cellular defenses within production cells. These natural defenses, designed to combat foreign genetic material and inhibit viral replication, can hinder your process. Our solution is a unique panel small molecules which make up our Viral Sensitizer (VSETM) platform, which dampen cellular defenses. Using an innovative high-throughput screening process, we have developed a library of novel VSEs. Virica continues to leverage this advanced technology to pinpoint the most synergistic Viral Sensitizer molecules from our library, tailored to any virus or cell line. We customize formulations of these Viral Sensitizers to enhance virus yield in your manufacturing process or optimize the effectiveness of your viral therapies. The result is higher yields and improved quality, helping to reduce costs and improve patient access.

Envisagenics was founded in 2014 as a spinout of Cold Spring Harbor Laboratory. Our mission is to reduce the complexity of biomedical data to accelerate the development of innovative therapeutic solutions through RNA splicing analytics and artificial intelligence. We focus on the discovery of RNA therapeutics. Over 30 million people in the US suffer from genetic diseases or cancer that could be caused by mutations affecting RNA splicing. 370 human diseases are known to be caused by splicing errors, and more remain to be discovered. Our breakthrough technology, SpliceCore, is a cloud-based platform that is experimentally validated to predict drug targets and biomarkers through splicing discovery from RNA-seq data, using Artificial Intelligence. We are using our software to identify splicing errors causative of diseases, identify the right drug-targets and develop RNA therapeutics through partnerships and collaborations with Biopharma. Our in-silico RNA therapeutics discovery platform replaces expensive drug-target selection and lead design with efficient computer simulations, decreasing time, cost, and failure risk of drug development programs.
