“The recent ASN meeting in Philadelphia provided us with numerous opportunities to meet and engage with nephrologists across the country, further cementing our belief that the strong long-term data from our Phase 3 trial, in combination with a potential full approval, will significantly impact how nephrologists view and use the product going forward. We reconfirm our guidance for 2023 of USD 100 – 120m of net sales from TARPEYO and look forward to an exciting 2024.”
