United Therapeutics and DEKA Announce Additional FDA Clearance Related to the Unity Subcutaneous Delivery System for Remodulin®

RESEARCH TRIANGLE PARK, N.C. and MANCHESTER, N.H., Feb. 24, 2020 /PRNewswire/ -- United Therapeutics Corporation (Nasdaq: UTHR) and DEKA Research & Development Corp. today announced receipt of an additional 510(k) clearance by the U.S. Food and Drug Administration (FDA) related to the Unity Subcutaneous Delivery System for Remodulin® (treprostinil) Injection, also referred to as the Remunity pump, enabling United Therapeutics to launch the system using drug reservoirs that have been prefilled by specialty pharmacies.

The Remunity system, which was jointly developed by United Therapeutics and DEKA, is indicated for continuous subcutaneous delivery of Remodulin to treat pulmonary arterial hypertension, or PAH, in adults greater than 22 years of age. The Remunity system includes a small, lightweight, ambulatory pump with an intended service life of three years, which the patient connects to a disposable prefilled cassette.    

The system was initially cleared by the FDA in May 2019 with instructions for patient filling. This additional 510(k) clearance enables cassettes to be prefilled with Remodulin by contracted specialty pharmacies in order to improve convenience for patients. United Therapeutics plans to launch the Remunity system by July 2020. United Therapeutics and DEKA are also developing a future version of the system that will include disposable components that are prefilled as part of the manufacturing process.

"We're super 'pumped' about launching Remunity by Independence Day," said Dr. Martine Rothblatt, Chairman and Chief Executive Officer of United Therapeutics. "Remunity will provide a new level of freedom to our patients through improved convenience, and we believe it will provide more free time to live their beautiful lives. The system provides a wider array of notifications, alerts, and alarms than current pumps. Most amazingly, the acoustic volume sensing technology and solid-state actuator of the Remunity system enables it to control Remodulin flow rates without the use of a motor. To me, because of so few moving parts, it is like the Tesla of parenteral pumps!"

"We are excited to be launching this innovative delivery technology with United Therapeutics. We are confident that the Remunity system, particularly with the additional convenience of cassettes prefilled with Remodulin, has the potential to improve the lives of patients who depend on UT's unique pharmaceutical advances," said Dean Kamen, Founder and President of DEKA. "We are extremely proud of UT's dedication to their patients and grateful to UT for their unwavering support of DEKA as we continue to develop and deliver advanced solutions to address the needs of those patients."

About Remodulin® (treprostinil) Injection

Indication or What is Remodulin?

Remodulin is a prescription medication used to treat adults with pulmonary arterial hypertension (PAH; WHO Group 1), which is high blood pressure in the arteries of your lungs. Remodulin can reduce symptoms associated with exercise. Remodulin was studied mainly in patients with NYHA Functional Class II-IV symptoms. It is not known if Remodulin is safe and effective in children. 

In people with PAH who need to switch from epoprostenol, Remodulin is approved to slow the worsening of symptoms.

Important Safety Information for Remodulin

Before you take Remodulin, tell your healthcare provider if you:

  • Have other medical conditions or take other medicines that may affect your use of Remodulin by increasing the risk of side effects or decreasing the drug's effectiveness.
  • Have liver or kidney problems. Your Remodulin dose may need to be adjusted if you have liver problems.
  • Have low blood pressure or bleeding problems.
  • Are taking gemfibrozil (for high cholesterol), rifampin (for infection) or other drugs that affect liver enzymes. Your doctor may need to adjust your Remodulin dosage.
  • Are pregnant, breastfeeding, or planning to become pregnant. It is not known if Remodulin will harm your unborn baby or if Remodulin passes into your breast milk.

What are the serious side effects of Remodulin?

  • Continuous intravenous (IV) infusions of Remodulin delivered using an external infusion pump, with a tube placed in a central vein within the chest, are associated with the risk of blood stream infections and sepsis, which may be fatal. Therefore, continuous subcutaneous (SC) infusion delivered just beneath the skin is the preferred type of delivery.
  • Worsening of PAH symptoms. Do not stop taking or greatly reduce your Remodulin dose without consulting your doctor.
  • Low blood pressure (symptomatic hypotension). If you have low blood pressure or are taking drugs that lower your blood pressure, the risk of low blood pressure is increased.
  • Bleeding problems. Remodulin may increase the risk of bleeding in people who take blood thinners (anticoagulants).

What are the possible side effects of Remodulin?

  • In clinical studies of SC infusion of Remodulin, most people experienced infusion site pain and infusion site reaction (redness, swelling, and rash). These symptoms were sometimes severe and sometimes required treatment with narcotics or discontinuation of Remodulin.
  • IV infusion of Remodulin delivered through an external pump has been associated with the risk of blood stream infections, arm swelling, tingling sensations, bruising, and pain.
  • The most common side effects seen with either SC or IV Remodulin were headache, diarrhea, nausea, rash, jaw pain, widening of the blood vessels (vasodilatation), and swelling from fluid retention (edema). These are not all the possible side effects of Remodulin. Call your doctor for medical advice about side effects.

You may report side effects to the FDA at www.fda.gov/MedWatch or call 1-800-FDA-1088.
