Interim Report Q3, 2021

A quarter of deal making and regulatory review

“Following on from the positive top line read out of Part A our Phase 3 study, we initiated a structured process to select our commercial partner for Nefecon in Europe. In this case, the result of the process was a partnership with Stada Arzneimittel, which has proven to be an excellent match. We also took the opportunity to complement our predominant source of equity capital with a $75m credit line from Kreos.

In the third quarter, the U.S. Food and Drug Administration (FDA) requested further analyses of data from the NeflgArd clinical trial in connection with our NDA submitted for approval under the FDA’s Accelerated Approval Program. The FDA classified the additional analyses received as a major amendment to the NDA and extended the PDUFA goal date by three months from September 15, 2021 to December 15, 2021. The third quarter also saw the European Medicines Agency (EMA) deciding to revert to standard review timelines for our submission, which we estimate will result in the issuance of an opinion in Q1, 2022. We remain confident that we have presented a compelling data package and look forward to continuing our regulatory interactions with the goal of making an approved treatment available for patients in need.

We remain ready for commercial launch in the US. Our field medical directors are in dialogue with nephrologists across the country and we are proceeding with market access related conversations as well as other pre-commercial activities. We are excited about our strong US capabilities reflected by the highly experienced and well-prepared team in place.“
