Trofinetide (NNZ-2566) is a drug developed by Neuren Pharmaceuticals that acts as an analogue of the neuropeptide (1-3) IGF-1, which is a simple tripeptide with sequence Gly-Pro-Glu formed by enzymatic cleavage of the growth factor IGF-1 within the brain. Trofinetide has anti-inflammatory properties and was originally developed as a potential treatment for stroke, but has subsequently been developed for other applications and is now in Phase II clinical trials against Fragile X syndrome and Rett syndrome.
Neuren Pharmaceuticals was created in 2004 via a merger of two companies that were formed around the University of Auckland in Auckland, New Zealand. The company now has registered offices in Australia and New Zealand. In 2005, Neuren Pharmaceuticals was listed on the Australian Securities Exchange (ASX) As a company that is publicly traded, Neuren Pharmaceuticals receives a large portion of its current funding from shareholders, since it currently has no drug products on the market. It is also largely funded by grants from companies or agencies with an interest in their project. In 2007, acquired venture-backed Hamilton Pharmaceuticals for $4.4 million in stock. Since the acquisition was stock-based, the three venture funds that had previously backed Hamilton Pharmaceuticals, Vivo Ventures, CNF Investments, and Index Ventures, became stockholders in Neuren Pharmaceuticals. As a result of the acquisition, Neuren pharmaceuticals gained control of the drug Motiva, a drug to aid treatment of neurological disorders such as Parkinson's and Alzheimer's disease. Motiva did not pass phase 2 clinical trials.
Neuren Pharmaceuticals received several grants from various sources for research on Trofinetide, including $26 million in funding from the United States army, who was interested in the drug for its use on TBI. This grant did include one point stating that an army scientist had to be used as a principal investigator. They also received funding from International Rett Syndrome Foundation, FRAXA, and National Fragile X Foundation at significantly lesser value.
Neuren's analyst through Bell Porter reported that the company's estimated earnings before interest, taxation, depreciation, and amortization will be 84$ million at the end of 2016. This amount is expected to decrease by the end of 2017 to $27 million. The promising results include estimates from upcoming licensing deals for Trofinetide and payment milestones from those deals. The product is expected to be available for commercial sale in 2019 for Rett Syndrome and in 2020 for Fragile X Syndrome.
