- The TETON trials in idiopathic pulmonary fibrosis (IPF) are a top priority, with the potential to significantly expand their market opportunity, as the IPF market is approximately three times the size of the pulmonary hypertension market.
What went wrong
- Potential competition from Merck's sotatercept in the PAH market could impact UTHR's growth. Management noted they wouldn't comment on Merck's product but acknowledged its presence, suggesting concerns about market dynamics.
- Uncertainty regarding FDA approval for IPF treatments may pose risks. Both ongoing IPF studies may need to be successful for registration, and the company hasn't recently discussed the filing strategy with the FDA.
- Capital allocation priorities may limit future share buybacks, potentially affecting shareholder returns. Management is focusing on the existing ASR and internal R&D initiatives, indicating uncertainty around future significant share repurchases.
Q&A Summary
-
IPF Filing Strategy
Q: Do both IPF studies need to succeed for filing?
A: Management said that while the FDA typically requires two positive studies for registration, they will discuss options if TETON 2 shows significant results. They expect TETON 2 results within a year since enrollment was completed early. -
DPI Approval and Data Readout
Q: What bridging study is needed for DPI approval in IPF?
A: They plan to confirm requirements with the FDA, possibly needing a small sub-study in the TETON OLE program. They will not conduct interim analyses but expect final TETON 2 results within a year after the follow-up period. -
Share Buyback Plans
Q: Any plans for another significant share buyback or ASR?
A: The company is focused on executing the existing $700 million ASR, in process until the end of September. They are committed to wise capital allocation, prioritizing R&D initiatives, corporate development, and the current share repurchase program. -
Tyvaso DPI Growth Drivers
Q: Can you elaborate on Tyvaso DPI drivers versus Nebulized Tyvaso?

PAH Market Dynamics
Q: Have you noticed changes in PAH referrals or starts?
A: The PAH business remains solid and strong, with robust referral and start growth in line with expectations, reflected in revenue.
