Interim Report Q1, 2021


Filing of New Drug Application submission to the FDA

“Following the positive top line readout of our pivotal Phase 3 trial NefIgArd, which met both the primary and key secondary endpoints with results being statistically significant and clinically relevant we commenced the regulatory filing process which ultimately resulted in the timely filing of the submission to the FDA in Q1 as planned. In April, we received the response from the Food and Drug Administration (FDA) who accepted the submission and granted Priority Review for the New Drug Application (NDA) for Nefecon. The FDA have set a Prescription Drug User Fee Act (PDUFA) goal date of September 15, 2021. During Q1, we also submitted a request for accelerated assessment to the EMA, which was granted on April 23rd. These grants reflect the perceived unmet medical need in IgAN by regulators and, in my view, also the strength and overall quality of our dossier.

In Q1, we also reported positive data from the Phase 1 study of setanaxib, our lead compound in our NOX inhibition pipeline, paving the way for the use of higher dosing in the pivotal Phase 2/3 study in PBC. We also hosted an R&D day in January where we laid out the clinical development strategy for the year, presenting the plans for our PBC study as well as the Phase 2b proof of concept study in head and neck cancer, both slated to start in the second half of 2021. The substantial preclinical work that has been generated shows compelling data regarding setanaxib’s impact on CAF (cancer associated fibroblasts), paving the way for a significantly improved reach of checkpoint inhibitors.

We also significantly built our US team during the quarter, adding a Head of Marketing, VP Medical Affairs and Head of Sales. We will continue to build our team in order to be ready to commercialize in Q4, if approved.”

Significant events after the end of reporting period, in summary

  • In April 2021, Calliditas was granted accelerated assessment procedure by the European Medicine Agency’s (EMA) Committee for Human Medicinal Products (CHMP) reducing the maximum timeframe for review of the application for marketing authorization.
