Advancement of Israeli biotechnology industry

In 1980, Aviv initiated and started "Biotechnology General Corp.", the first Israeli Biotechnology company focusing on Recombinant DNA (genetic engineering), which exists to this day. The foundation of the company was encouraged by Ephraim Katzir, formerly the president of Israel, and was supported by a group of investors led by Mr. Fred Adler, one of the leading Venture Capitalists. After he retired from "Biotechnology General Ltd.", Aviv founded "Diatech Ltd." which specialized in medical diagnostic tools, and "Pharmos Corp."- In which he served as chairman and CEO. Pharmos initially focused on development of drugs for the treatment of Eye disease ( Lotemax), but was mostly known for its later work to develop an innovative drug invented by Professor Raphael Mechoulam from the

( Dexanabinol), a synthetic canabinoid to treat head injury victims. Despite promising results in Phase 2 clinical trials, the large scale phase 3 clinical trials did not meet expectations. The lack of success in the trials provoked a negative response from the company's investors and the Israeli media. Aviv left his position at Pharmos in 2007. However, these clinical trials remain to this day the largest trials performed in the field of pharmaceutical treatment of head injury. Serious traumatic head injuries remain to this day a medical challenge. In 2000, Aviv founded "Predix Corp.", which focused on development of pharmaceuticals using advanced computerization and three-dimensional algorithms, invented by Dr. Oren Becker. As of 2011, Aviv focused his work in the company "Herbamed Ltd.", as chairman and major shareholder. Herbamed is an Israeli company which develops health-supporting food products ( Functional Foods) and

Among his major recommendations was the establishment of dedicated investment funds with the aid of government funding, a recommendation which is currently being implemented with the foundation of two large-scale funds which include government aid.
