On Aug. 25, 2025, MannKind and scPharmaceuticals announced the signing of a definitive merger agreement for MannKind to acquire scPharmaceuticals.

This proposed acquisition marks MannKind’s strategic expansion into cardiorenal medicine, establishing the company’s cardiometabolic business alongside its orphan lung division. scPharmaceuticals currently markets FUROSCIX, an FDA-approved on-body infuser delivering furosemide, the gold standard to treat fluid overload in adult patients with chronic heart failure (CHF) and chronic kidney disease (CKD). The estimated total addressable market opportunity equates to more than $10 billion in the U.S. alone.

scPharmaceuticals has demonstrated strong commercial momentum with its 2024 sales force expansion, ongoing launch into nephrology and accelerating growth in integrated delivery networks. For the six months ended June 30, 2025, net sales totaled $27.8 million, up 96% year-over-year.

The FUROSCIX ReadyFlow Autoinjector is on track for a Q3 2025 supplemental New Drug Application (sNDA) submission, potentially enabling patients to reduce treatment time from five hours to less than 10 seconds.

Under the terms of the definitive merger agreement, MannKind will promptly commence a tender offer to acquire all of the outstanding shares of scPharmaceuticals common stock at a price of $5.35 per share in cash at closing plus one non-tradable CVR per share to receive certain milestone payments of up to an aggregate of $1.00 per CVR in cash, for total consideration of up to $6 .35 per share in cash, representing a total equity value of approximately $303 million at closing and representing a total deal value of up to approximately $360 million.
