BIOMAG-I Data Shows No New Events between Two and Three Years in Target Lesion Failure with Freesolve Resorbable Magnesium Scaffold Excellent Patient Outcomes Confirmed with Long-Term Safety and Efficacy
New results from the BIOMAG-I first-in-human trial demonstrated an excellent safety and efficacy profile for Freesolve®, BIOTRONIK’s third-generation resorbable magnesium scaffold (RMS) at three years follow-up. Prof. Dr. Michael Haude presented these new data at the EuroPCR 2025 conference in Paris.
At the 36-month follow-up, the target lesion failure (TLF) rate remained at 3.5%, consisting of four cases of clinically driven target lesion revascularization (CD-TLR), of which only one event occurred beyond the resorption period of the scaffold. No cases of target-vessel myocardial infarction, cardiac death, or definite/probable scaffold thrombosis occurred.1
BIOMAG-I is a prospective, multicenter, single-arm, first-in-human trial conducted in Europe. A total of 116 patients represented with single de novo lesions in up to two coronary arteries were included in the trial. Three-year data were available for 112 patients.
“These outcomes show that Freesolve RMS is a viable therapy option combining both temporary mechanical support and excellent long-term safety,” said Prof. Michael Haude, Rheinland Klinikum, Neuss, Germany. “It was particularly interesting to observe that the TLF rate plateaued after two years. This indicates that the RMS performed as intended: providing temporary vessel support and subsequently disappearing to prevent long-term complications.”
Initial findings from the one-year follow-up of the BIOMAG-I study2 revealed excellent median late lumen loss of 0.19 mm. Additionally, optical coherence tomography confirmed complete strut resorption of the Freesolve RMS after 12 months.2
“We eagerly anticipate RCT data from the international BIOMAG-II trial to further demonstrate Freesolve RMS as a more physiologic alternative to contemporary drug-eluting stents with improved long-term outcomes,” said Prof. Dr. Georg Nollert, Vice President Medical Affairs, Vascular Intervention at BIOTRONIK. “Given the increasing body of evidence for magnesium scaffolds, we believe the medical community may reconsider the guidelines on revascularization in the future.”
