Interim Report Q1, 2020

NefIgArd proceeding according to plan

“In the end of the first quarter of 2020 much of the activity at the company was focused on assessing and mitigating any potential impact Covid-19 might have on NefIgArd and I am happy to report that, due to the fact that the Part A of the study was fully recruited in December 2019, Nefecon is an oral formulation which patients are able to take at home and that the study doesn’t require significant interactions with the healthcare system, the impact to date has been limited and our communicated timeline remain intact”

Renée Aguiar-Lucander, CEO
