Feb 15 Apricus Biosciences Inc said its unit NexMed licensed the German marketing rights to its erectile dysfunction drug to Novartis AG's Sandoz unit for up to 21 million euros ($27.4 million) and royalties.
Apricus said it will receive double digit royalties on sales of Vitaros, apart from the upfront and milestone payments.
