A heart-failure injector delivers a full dose in under 10 seconds. Urine output was similar to treatment into a vein.
MannKind (MNKD) presented clinical data at HFSA 2026 showing Furoscix ReadyFlow's comparable urine output to IV furosemide. The autoinjector delivers an 80 mg/mL dose in under 10 seconds, with 91.3% and 92.7% bioavailability in thigh and upper-arm injections, respectively. ReadyFlow received FDA approval in July 2026 for fluid overload treatment in heart failure or CKD patients.

Background
MannKind's Furoscix ReadyFlow received FDA approval in July 2026; the new data further characterize its pharmacokinetic/pharmacodynamic profile.
Ticker impact
MannKind announced new clinical data showing Furoscix ReadyFlow autoinjector achieves bioequivalence to IV furosemide, supporting outpatient heart‑failure and CKD treatment.
likely upward pressure as market prices in the new efficacy evidence
First disclosure of bioequivalence results; analysts typically reward biotech firms for supportive trial outcomes.
Market effects
strengthens outlook for outpatient heart‑failure therapies and may benefit peers in the diuretic/renal‑failure space
U.S. biotech sector may see modest uplift
limited to niche therapeutic market
Counterpoint
Data are from separate study populations; efficacy may not translate to broader real‑world use
