Reva Medical: New Fantom Data Demonstrates Safety at 2 Years

SAN DIEGO, Oct. 31, 2017 (GLOBE NEWSWIRE) -- The Fantom bioresorbable scaffold from REVA Medical (ASX:RVA) shows continued positive clinical outcomes according to an interim data set from the FANTOM II clinical trial presented this week at the Transcatheter Therapeutics Conference (“TCT”) in Denver, Colorado. The Company also revealed plans for its next generation scaffold, named Fantom Encore, which will have a market-leading 95 micron strut thickness for the 2.5 mm diameter scaffold.

Clinical outcomes were reported for an interim data set of 125 patients followed through 24 months. Findings included a low rate of Major Adverse Cardiac Events (“MACE”) of 5.6% and a single very late scaffold thrombosis event. REVA previously reported a MACE rate of 4.2% through 12 months for the complete 240-patient data set with a single scaffold thrombosis event in the sub-acute time frame. The 24-month outcomes demonstrate a sustained safety profile for Fantom.

In addition to clinical follow up, a 25-patient subset in the trial underwent angiographic imaging to determine late lumen loss (“late loss”) at 24 months. Late loss is the difference between the diameter of a stented segment immediately after treatment compared with the follow-up angiogram. The clinical data showed a final in-scaffold late loss of 0.25 mm, which is in the desired range of 0.2 mm to 0.4 mm. This range historically corresponds with positive long-term outcomes for stents and scaffolds.

The data were presented in a moderated poster session by trial investigator, Dr. Ricardo A. Costa, from Institute Dante Pazzanese of Cardiology in Sao Paulo, Brazil, and in an oral presentation by Dr. James B. Hermiller Jr., from the Heart Center of Indiana in Indianapolis, Indiana.

“This preliminary data set from the FANTOM II trial provides physicians with an early look at two-year clinical results for the Fantom scaffold,” said Dr. Costa. “The low MACE rate and in-scaffold late lumen loss measurement are encouraging as they demonstrate sustained safety and performance of Fantom out to 24 months in this group of patients.”

The FANTOM II trial is evaluating the safety and performance of the Fantom sirolimus-eluting bioresorbable coronary scaffold in 240 patients outside of the United States. Six-month data from the FANTOM II trial was used as the basis for European CE Marking for Fantom, which was granted in April of this year.

REVA also announced plans for a 95 micron strut thickness scaffold. The new scaffold, named Fantom Encore, will utilize the same polymer as Fantom called Tyrocore, REVA’s proprietary tyrosine-derived polymer designed specifically for vascular scaffold applications. Tyrocore is inherently radiopaque, making Fantom and Fantom Encore visible under fluoroscopy. Additionally, Tyrocore is strong, enabling thinner struts while retaining radial strength. Fantom

Encore will be available in 2.5, 3.0 and 3.5 mm diameters. The 95 micron struts will be available on the 2.5 mm diameter scaffold.

“REVA’s announcement of 95 micron strut thickness for Fantom Encore in the 2.5 mm diameter is a promising development for bioresorbable scaffold technology,” stated Dr. Hermiller. “Bioresorbable scaffolds have the potential to offer patients short term benefits of metallic stents without the long-term complications. Thinner struts have been associated with improved deliverability and vessel healing.”

About Fantom

Fantom is a sirolimus-eluting bioresorbable scaffold developed as an alternative to metallic stents for the treatment of coronary artery disease. Scaffolds provide restoration of blood flow, support the artery through the healing process, and then disappear (or “resorb”) from the body over a period of time. This resorption is intended to allow the return of natural movement and function of the artery. Fantom is the only bioresorbable scaffold made from Tyrocore, REVA’s proprietary tyrosine-derived polymer designed specifically for vascular scaffold applications. Tyrocore is inherently radiopaque, making Fantom the first and only bioresorbable scaffold that is visible under fluoroscopy. Fantom is designed with thin struts while maintaining strength and with distinct ease-of-use features such as expansion with one continuous inflation.
