A brief history of Opthea Limited
Circadian Technologies changed its name to Opthea Limited in December 2015. Coinciding with the name change, the company’s ASX code changed from CIR to OPT.
Circadian Technologies was founded by Leon Serry and was one of Australia’s earliest biotechnology companies, listing on the Australian Securities Exchange in 1985.
Originally functioning as a commercial vehicle for outstanding, diverse biomedical research, the company successfully launched and spun out many of Australia’s most prominent biotechnology companies including Axon Instruments, Optiscan Imaging and Antisense Therapeutics.
In 2008, Circadian transformed its strategy to concentrate on the development of biologics-based therapies. In 2014, as Opthea, the company focussed operations on the commercial potential residing in OPT-302 for retinal eye diseases. The company’s programs leverage the broad intellectual property in respect of VEGF-C, VEGF-D and VEGFR-3, which is held within Opthea’s wholly-owned subsidiary, Vegenics Pty Ltd.
