Selution SLR receives second FDA IDE approval


Selution SLR, MedAlliance’s sirolimus-eluting balloon, has received conditional Food and Drug Administration (FDA) investigational device exemption (IDE) approval to initiate its pivotal clinical trial for the treatment of occlusive disease of the superficial femoral artery (SFA).

This comes only a few months after the company received IDE approval for Selution SLR in the treatment of below-the-knee (BTK) indications (May 2022).

Enrollment will begin in the SELUTION SLR IDE SFA study later this year. It will be conducted at over 20 centers in the U.S. and an additional 20 centers around the world. This study will enroll 300 patients to demonstrate superiority over balloon angioplasty (POBA). The principal investigator of this study is George Adams, MD, the director of cardiovascular and peripheral vascular research at Rex Hospital in Raleigh, North Carolina.

“We are very excited that U.S. patients suffering from PAD [peripheral arterial disease] will have the opportunity to receive this novel sirolimus drug-coated balloon technology. This is yet another advancement in the field of treating vascular disease and we are confident that this study will enroll quickly,” Adams commented.

Selution SLR was awarded CE mark approval for the treatment of PAD in February 2020 and for the treatment of coronary artery disease in May 2020. The FDA has awarded Selution SLR four breakthrough designations: for the treatment of atherosclerotic lesions in native coronary arteries; coronary in-stent restenosis; peripheral below-the-knee; and AV-fistula indications.

In August 2021, the first of over 3,000 patients was enrolled in a ground-breaking coronary randomized controlled study comparing Selution SLR with any limus drug-eluting stent [DES]. This is the largest drug-eluting balloon (DEB) study ever initiated.

MedAlliance’s DEB technology involves MicroReservoirs made from biodegradable polymer intermixed with the anti-restenotic drug sirolimus. These MicroReservoirs provide controlled and sustained release of the drug for up to 90 days. Extended release of sirolimus from stents has been proven highly efficacious in both coronary and peripheral vasculatures. MedAlliance’s proprietary CAT (Cell Adherent Technology) enables the MicroReservoirs to be coated onto balloons and adhere to the vessel lumen when delivered via an angioplasty balloon.
