Medivir gets 2,6 MUSD following regulatory approval to start clinical trials with the HIV antiviral MIV-150

Medivir gets 2,6 MUSD following regulatory approval to start clinical trials with the HIV antiviral MIV-150 Medivir receives a 2,6 MUSD milestone payment following Chiron's receipt of clearance from the relevant authority to start clinical trials in the UK. Earlier this year Medivir outlicenced the HIV antiviral substance MIV-150 to Chiron Corporation. The agreement gave Chiron the exclusive rights to the global marketing and sales of the HIV drug MIV-150. Medivir received 5 MUSD on signing. If MIV-150 is successful, Medivir would receive up to a total of 35 MUSD upon reaching specified milestones, as well as royalties up to the year 2017, under the Chiron contract. Medivir recently received 3 MUSD as a milestone payment following a decision by Chiron to begin the regulatory process for initiating phase I clinical trials. In total Medivir has now received 10,6 MUSD this year for this project.
