What is the long-term safety of treprostinil excipient contains in Lyumjev® (insulin lispro-aabc)?
In Lyumjev formulation, the microdoses of treprostinil used as an excipient induce only a local vasodilation effect. Treprostinil was not measurable in the blood circulation, and no systemic effects were seen.
Treprostinil - Long Term Safety
Remodulin® (treprostinil) injection has been approved to treat pulmonary arterial hypertension (PAH) for approximately 20 years and the safety profile is established.1
In the treatment of PAH, treprostinil is used at initial doses of 1.25 ng/kg/min as a continuous infusion and achieves an average steady state concentration that is at least 200‑fold higher than the levels in patients treated with Lyumjev® (insulin lispro-aabc).1,2
In the formulation of Lyumjev, microdoses of treprostinil are used as an excipient to increase blood flow at the site of injection through localized vasodilation.3-5
The commercial formulation of Lyumjev contains 10 ng of treprostinil per unit of insulin lispro in a 100 unit/mL formulation.2
Treprostinil was not measurable in the blood circulation, and no systemic effects were seen with bolus doses of Lyumjev up to 50 units in phase 1b studies.3-5
