FDA Approves new Lasix injection for Edema in Chronic Heart Failure
FDA has approved the new furosemide injection for treating edema in adults with chronic heart failure.
Lasix ONYU was developed to enable subcutaneous infusion of furosemide outside the healthcare setting for selected patients, as prescribed by a clinician without the need for a healthcare professional to administer the drug.
About 6.7 million Americans suffer from heart failure, with the prevalence expected to rise to 8.7 million by 2030. Heart failure is a leading cause of hospitalizations for individuals aged 65 and older with approximately 1.2 million hospitalizations per year.
Lasix ONYU consists of a novel high-concentration formulation of furosemide combined with a state-of-the-art small Infusor for treatment at home. The innovative design includes a reusable unit that can be used for 48 treatments and a plastic sterile single-use unit that is discarded after treatment. The two-component design reduces manufacturing complexity and cost, allowing the product to be offered at a different, more favorable price point which is expected to reduce barriers to widespread adoption.
"Lasix ONYU has the potential to be transformative in the care of patients experiencing worsening heart failure due to fluid overload," said Pieter Muntendam, MD, founder, President and CEO of SQ Innovation. "Treating selected patients at home offers important benefits to patients, health systems and payors. We look forward to launching Lasix ONYU with leading health systems in the 4th quarter of 2025."
Bioavailability and diuretic response were determined in a clinical study in which Lasix ONYU demonstrated complete bioavailability (112%) resulting in similar diuresis (115%) and natriuresis (117%) when compared to the same dose given by IV bolus. The biphasic delivery of furosemide by the Infusor resulted in a tempered diuretic response while IV bolus administration led to a shorter period of more intense diuresis. The results of the study were published in a leading cardiovascular journal.
"Heart failure is the most common serious medical condition in the U.S. and affects about one in four Americans during their lifetime. The number of patients affected is expected to double over the next 20 years and we currently already often lack adequate resources to take care of the 6.7 million patients affected presently – there are not enough beds, clinicians and funds", said Dr. Javed Butler, Professor of Medicine at University of Mississippi and President, Baylor Scott and White Research Institute. "The only two actionable solutions now are more widespread adoption of guideline directed medical therapy (GDMT) and treating more patients at home with products such as subcutaneous diuretics instead of hospitalization for intravenous diuretics."
"Decongestion through use of IV diuretics has been the cornerstone of treatment for reducing edema and hypervolemia in heart failure patients for over five decades," stated S. Craig Thomas, Immediate Past President of the American Association of Heart Failure Nurses (AAHFN), an organization dedicated to advancing nursing education, clinical practice, and research to improve outcomes for heart failure patients. "The availability of accessible, affordable, and novel options that do not require the presence of a healthcare professional allows for transformative new clinical care-delivery. This means patients who now would typically need to be hospitalized for several days of IV treatment can instead remain home, supported by periodic or remote monitoring. The significance of this shift away from inpatient care for patients, hospitals, and payers cannot be overstated."
Starting this quarter, Lasix ONYU will be available from leading pharmaceutical distributors enabling timely availability at participating medical facilities and affiliated retail pharmacies.
SQ Innovation is hosting a Conference Call and Webcast on Thursday October 9, at 4:30pm ET to introduce the product and answer questions from the community. Participating in the conference call will be:
• Pieter Muntendam, MD, President and CEO of SQ Innovation
• Mustafa M. Ahmed, MD, Professor of Medicine, Section Chief, Heart Failure, University of Florida Health, Gainesville, FL
• S. Craig Thomas, Nurse Practitioner, Advanced Heart Failure Center, University of Virginia Health System, Charlottesville, VA and Immediate Past President American Association of Heart Failure Nurses (AAHFN).
About Lasix ONYU
Lasix® ONYU is a drug-device combination that was approved by the U.S. Food and Drug Administration on October 7, 2025 for the treatment of edema in adult patients with chronic heart failure. The pharmaceutical component of Lasix ONYU is a novel, high-concentration formulation of the diuretic furosemide, at 30 mg/mL. It comes in a pre-filled glass cartridge containing 80 mg of furosemide in 2.67 mL. The Lasix ONYU Infusor consists of two main parts: the Reusable Unit and the Disposable Unit. The Reusable Unit is an electromechanical device that contains the battery, motor, and electronic components necessary for operation and safety functions. It can be used up to 48 times before it can be recycled. The Disposable Unit is a sterile, single-use plastic component that holds the drug cartridge. It includes a micropiston pump, fluid path, needle insertion and retraction mechanism, and a 29-gauge needle. After placement on the abdomen, the needle penetrates the skin when the device is activated. The Lasix ONYU Infusor slowly administers 80 mg furosemide over a period of five hours. This method results in significant diuresis similar to IV, but in a more controlled manner. This avoids the brief, intense diuretic effect that occurs with rapid IV infusion or injection. The advanced two component design offers benefits for patients, healthcare providers, payers, and the environment.
