Promosome LLC 6/12/2018 Promosome is a New York City based biotechnology company with facilities in La Jolla CA and a research relationship with The Scripps Research Institute. Founded in 2003 by the highly regarded life sciences team of John R. Costantino and William J. Gedale, to commercialize the discoveries of Nobel Laureate Dr. Gerald Edelman, his colleague Dr. Vincent Mauro and other researchers at The Scripps Research Institute in La Jolla, CA. The expertise and continued focus of this research team at Scripps is in areas of Gene Regulation and Protein Expression through Translation Initiation. Through this expertise the Scripps team has developed a world leading understanding of mRNA translation and has established several commercially applicable technologies with an emphasis on serving the therapeutic and industrial bioproduction space.

Promosome LLC & The Scripps Research Institute 6/12/2018 Promosome LLC & The Scripps Research Institute The Scripps Partnership: Promosome and TSRI are currently completing the third consecutive 2 Year Research Funding and Option (RFO) Agreement extension specific to the laboratories of Drs. Edelman and Mauro. Promosome and TSRI anticipate the relationship to continue into a fourth consecutive extension. Through the RFO, Promosome has exclusive, sole, worldwide rights to license any and all translational discoveries related to bioproduction, DNA Vaccines and other applications developed under the funding arrangement. Scripps holds a 10 % founder’s equity interest, subject to normal dilution – No Future Royalties.
