EU Sales Plans of Vivagel BV

I have a hard time understanding why Starpharma has yet to begin commercializing Vivagel in the EU. They received commercial approval for the product 2 years ago yet they have not registered any sales there. I think the Starpharma management has taken the wrong approach in commercializing the product. They should have already begun commercializing the product in the EU (Germany/UK/France to start) as a test case to further raise awareness about the efficacy of the product within the global medical community. In doing so, they would have facilitated the successful commercial expansion of the product in other markets including rest of EU, USA. I think they have wasted a great opportunity to make the commercialization of the product a real success. Assuming they receive PMA approval from the FDA in the second half of 2018, how long will it take them to begin earning a significant amount of revenue from Vivagel? 2020?2021?2022?
