Calliditas is currently running a pivotal, global phase 3 clinical trial with Nefecon for the treatment of patients with IgAN. This agreement gives Everest Medicines exclusive rights to develop and commercialise Nefecon in China, Hong Kong, Macau, Taiwan and Singapore and may, depending on the outcome of consultation with the relevant regulatory authorities, lead to the inclusion of

Chinese study centres in the ongoing pivotal study, NefIgArd , with the result of achieving registration approval for the Chinese market on an accelerated basis.

Following potential registration approvals, Everest will be responsible for the commercialization of Nefecon in the relevant territories.

The first 200 randomised patients in the ongoing pivotal NefIgArd study will form the basis for topline data readout expected to occur during the second half of 2020, following which Calliditas will submit the applications for accelerated/conditional regulatory approval to the US Food and Drug Administration and the European Medicines Agency respectively.
