Year-End Report 2019

Recruitment for NefIgArd part A completed on plan and budget

“In the last quarter of 2019, we achieved a major milestone: the full recruitment of 200 patients for Part A of our pivotal Phase 3 study, NefIgArd. We continue to expect to read out top line data in Q4 2020 as projected at the start of the study, based on the 9 months treatment period. Another key event during the quarter was the acceptance by the Chinese authorities, NMPA, of the IND filed in China by Everest Medicines. The acceptance triggered one of several milestones under the agreement, resulting in a USD 5 million milestone providing additional capital for clinical development programs.”
