Trophogen

Trophogen, Inc. is a biotechnology company based in Rockville, Maryland.

The company was founded in 2001 with Series A funding from Toucan Capital, focusing on the development of human and bovine high affinity glycoprotein hormone and related growth factor superagonist analogs for human infertility and animal superovulation, as well as targeted therapy and imaging of thyroid, ovarian, breast, prostate and testicular cancers.

Technology
Trophogen's claims that it produces long acting superagonist effects by engineering new analogs to increase their affinity to the receptor. This is achieved by substituting certain amino acids in the receptor binding domain, increasing affinity up to 100 fold. The addition of neoglycosylation sites extends the half-life of those analogs without extensions or subunit linkers, improving treatment convenience by reducing the number of injections. Trophogen's technology represents the first successful design of super active analogs of glycoprotein hormones that shows major increases in bioactivity and exceeds results shown for other protein ligands
