Four‑Year BIOMAG™-I Study Results Presented at EuroPCR Confirm Long‑Term Safety and Sustained Performance of the Freesolve™ Resorbable Magnesium Scaffold (DREAMS 3G)

Key Terms

target lesion failure medical

Target lesion failure is a clinical-trial outcome that measures whether a specific treated segment of a blood vessel causes serious problems after an intervention — typically defined as death related to the heart, a heart attack in the treated area, or the need for another procedure on that same spot. For investors it’s a compact gauge of a device or treatment’s effectiveness and safety, like a warranty score for a repaired pipe: fewer failures suggest better performance, faster regulatory approval, stronger sales and lower long-term costs.

target-vessel myocardial infarction medical

A target-vessel myocardial infarction is a heart attack that occurs in the same coronary artery that was previously treated or targeted during a medical procedure, such as stent placement or bypass. For investors, it signals a procedure or device may have failed to prevent a recurrence or caused a complication, which can affect clinical trial results, product approvals, liability, patient demand and the financial outlook for healthcare companies — like a repaired pipe bursting again at the same spot.

scaffold thrombosis medical

Scaffold thrombosis is the formation of a blood clot on or around a temporary scaffold — a tube-like medical device used to prop open a blocked artery — which can block blood flow and cause heart attack or other serious complications. Investors should care because occurrences affect a device’s safety profile, regulatory approvals, clinical adoption and liability exposure, much like a recalled part erodes trust and sales for a manufactured product.

drug-eluting stents medical

Drug-eluting stents are small tube-like implants placed inside narrowed arteries that slowly release medicine to prevent the vessel from closing again after it’s widened, acting like a scaffold that also delivers a slow-release treatment to stop re-growth. They matter to investors because they are a high-value medical device category that drives procedure volumes and company revenue, while being sensitive to regulatory approval, patents, competition and reimbursement decisions that can change sales and margins.

bioresorbable scaffolds medical

A bioresorbable scaffold is a temporary implant used to prop open a blocked or narrowed blood vessel and then gradually dissolves and is absorbed by the body, like a construction scaffold that is removed once the building can stand on its own. For investors it matters because these devices aim to replace permanent metal implants, offering potential advantages in long‑term patient outcomes, market growth, and recurring sales, while also carrying regulatory, clinical trial and reimbursement risks that affect commercial success.

randomized controlled trials medical

Randomized controlled trials are studies where participants are randomly assigned to receive either a new treatment or a comparison (such as a standard treatment or placebo), so outcomes can be fairly compared like flipping a coin to decide teams. For investors, they matter because they provide the most reliable evidence about whether a drug, device or intervention actually works and is safe, which influences regulatory approval, market demand and the financial outlook of companies developing them.

resorbable magnesium scaffold medical

A resorbable magnesium scaffold is a temporary, tube-like medical implant made from a magnesium alloy that holds open a blocked blood vessel and then gradually dissolves and is absorbed by the body. Investors care because it promises the benefits of a traditional permanent stent while reducing long-term complications and repeat procedures, so its clinical performance, regulatory approval, and reimbursement determine market adoption and commercial value.

magnesium alloy medical

An alloy made mainly of magnesium mixed with small amounts of other metals to make a material that is lighter than aluminum but still strong. Investors care because it’s a key raw material for products where cutting weight matters — like cars, planes and consumer electronics — so its cost, availability and recyclability can affect manufacturers’ production costs, product performance and profit margins.

Persistently Low Target Lesion Failure and No New Cardiac-Related Event

WAYNE, Pa.--(BUSINESS WIRE)-- Teleflex Incorporated (NYSE: TFX), a leading global provider of medical technologies, today announced the four‑year follow‑up data from the First-in-Human BIOMAG™-I Clinical Study (NCT04157153)* presented at the EuroPCR conference in Paris, France by Prof. Jan Torzewski (Klinikverbund Allgäu, Germany).

Conducted exclusively across European centers and enrolling 116 patients, the study continues to demonstrate a favorable long‑term safety profile¹, with no new cardiac‑related¹ events observed between two and four years follow‑up period, establishing the third-generation Freesolve™ Resorbable Magnesium Scaffold (RMS) as a valuable treatment option.

Prof. Torzewski presented the results during the session “Lessons from the long‑term DES data: how can they inform today’s practice,” highlighting the relevance of long‑term ‘leave nothing behind’ approach with novel technologies in modern interventional cardiology.

Importantly, no cardiac death¹, no target-vessel myocardial infarction (TV-MI)¹, and no definite or probable scaffold thrombosis¹ have been observed through four years¹. The target lesion failure (TLF**) rate was 3.5%¹, impelled by the clinically-driven-target lesion revascularization (CD-TLR)¹, of which only one event occurred beyond the resorption period of the scaffold (at 1-year)². These findings reinforce the safety profile³, and sustained device performance³ of the Freesolve™ RMS.

“These long‑term BIOMAG™-I First-In-Human Study data continue to support the safety and performance of the Freesolve™ Scaffold,” said Prof. Michael Haude^ǂ, Principal Investigator of the BIOMAG™-I Study. “The absence of cardiac death, target‑vessel MI, or scaffold thrombosis throughout four years, combined with the very low TLF rate, is highly promising and aligns with the vascular healing response we aim to achieve with bioresorbable technologies.”

A Promising Path Toward Future Randomized Evidence

The continuing favorable 4‑year outcomes further support the potential of this resorbable scaffold as a viable treatment option, offering temporary mechanical support while maintaining excellent long‑term safety and efficacy.

“Our focus is on enabling durable clinical outcomes, so we’re delighted to see this plateau of events continuing out to 4 years,” said Prof. Dr. Georg Nollert, Vice President Medical Affairs at Teleflex. “This gives us even more confidence that RMS could be a valuable option for treating patients where the aim is to avoid a permanent implant.”

These results provide a strong foundation for the ongoing BIOMAG™‑II and pending BIOMAG™‑III Randomized Controlled Trials, both of which will be critical in demonstrating Freesolve™ RMS as a competitive alternative to contemporary drug‑eluting stents (DES).

Bioresorbable scaffolds have been developed to provide temporary mechanical support, and to prevent long-term stent-related adverse events³. Freesolve™ RMS is made of the proprietary BIOmag™ Magnesium Alloy and maintains a resorption time of 12 months⁴.
