Strong eGFR Data from Positive NefIgArd Phase 3 Trial Readout

“In March we announced that the global NefIgArd Phase 3 trial successfully met its primary endpoint, estimated glomerular filtration rate (eGFR), with a p value < 0.0001. Achieving this clinically relevant endpoint of kidney filtration capability represents a crowning achievement after well over a decade of pioneering work in IgA nephropathy. Nefecon, commercially available in the US and Europe under the brand name TARPEYO® and Kinpeygo® respectively, seems to be disease modifying, having shown both immediate and enduring kidney protective capability, with the treatment effect remaining intact even after 15 months off drug. In addition, the trial showed a significant proteinuria (UPCR) reduction of 34% versus optimized and stable standard of care at 9 months, and importantly also demonstrated that the proteinuria reduction was durable with similar levels recorded even after patients were off drug for 15 months. These benefits and the durability of treatment were observed across the entire study population, irrespective of UPCR levels. This highly differentiated approach, of targeting the origin of the disease with a locally active treatment that focuses on the production of secretory galactose-deficient IgA1, has generated what we believe is groundbreaking data showing a unique and impressive impact on eGFR. We are confident this data will not only impact clinical practice but also provide hope for the thousands of patients for whom there has been no appropriate medication to address their continued progression towards end stage renal disease. 

We are planning to file for full approval of the entire study population with the FDA in July, which would then enable a regulatory decision in the first half of 2024. The exact timing of this decision is dependent on whether the process would be conducted under priority or standard review.

In the US, we reported a record of 408 enrollments for the quarter, reflecting a weak January but a strong March. As the published interim data continues to become better known and understood throughout the broader nephrology community, we expect this trend of increased enrollments to continue over the year and to build towards our revenue guidance of USD 120-150 million for 2023. Total Q1 revenues were SEK 191.4 million, of which net revenues from TARPEYO amounted to SEK 185.7 million (USD 17.8 million). The growth in unique prescribing nephrologists was the highest to date with 276 new prescribers in Q1. Our cash position remains strong with SEK 1,013.6 million on the balance sheet, which we believe will be sufficient to take us to profitability.”

Summary of Q1 2023

January 1 – March 31

  • Net sales amounted to SEK 191.4 million, of which TARPEYO net sales amounted to SEK 185.7 million, for the three months ended March 31, 2023. For the three months ended March 31, 2022 net sales amounted to SEK 49.7 million, of which TARPEYO net sales amounted to SEK 18.0 million.
  • Operating loss amounted to SEK 180.1 million and SEK 208.4 million for the three months ended March 31, 2023 and 2022, respectively.
  • Loss per share before and after dilution amounted to SEK 3.49 and SEK 3.95 for the three months ended March 31, 2023 and 2022, respectively.
  • Cash amounted to SEK 1,013.6 million and SEK 825.4 million as of March 31, 2023 and 2022, respectively.

Significant events during Q1 2023, in summary

  • In February 2023, Calliditas announced that the Medicines and Healthcare products Regulatory Agency (MHRA) of the United Kingdom granted Conditional Marketing Authorization (CMA) for Kinpeygo for the treatment of primary immunoglobulin A nephropathy (IgAN) in adults at risk of rapid disease progression with a urine protein-to-creatinine ratio (UPCR) ≥1.5 g/gram. Kinpeygo became the first and only approved treatment for IgAN in the UK.
  • In March 2023, Calliditas announced positive topline results from the global, randomized, double-blind, placebo-controlled Phase 3 clinical trial NefIgArd, which investigated the effect of Nefecon (TARPEYO/Kinpeygo (budesonide) delayed release capsules) versus placebo in patients with primary IgA nephropathy. The trial met its primary endpoint with Nefecon demonstrating a highly statistically significant benefit over placebo (p value < 0.0001) in kidney function measured by estimated glomerular filtration rate (eGFR) over the two-year period of 9-months of treatment and 15-months of follow-up off drug.

Key Takeaways:

·  In March the global NefIgArd Phase 3 trial successfully met its primary endpoint, estimated glomerular filtration rate (eGFR) with a p value < 0.0001. Also, supportive 2-year total slope analyses were statistically significant and clinically meaningful reflecting a sustained treatment benefit. The eGFR benefit was observed across the entire study population, irrespective of urine protein-to-creatinine ratio (UPCR) baseline, which the company believes supports a regulatory filing with the FDA, planned for July 2023, for full approval in the study population.

  • In the first quarter of 2023, a record level of 408 new enrollments were generated, reflecting a growth of over 30% from Q4, 2022.
  • The growth in unique prescribing nephrologists was also the highest to date with 276 new prescribers in Q1, resulting in a total of 918 unique prescribers since launch.

2023 Outlook Unchanged

For 2023, Calliditas expects revenue growth in the U.S. where:

Net sales from TARPEYO are estimated to be USD 120-150 million for the year ending December 31, 2023.
