InspireMD Announces 30-Day Results from the CGUARDIANS II Clinical Trial of the CGuard Prime 80 cm Implant for Use in TCAR Procedures

(Neutral)

InspireMD (Nasdaq:NSPR) reported 30-day results from the CGUARDIANS II pivotal trial of its CGuard Prime 80 cm stent for TCAR procedures. In 50 patients, acute device success was 100%, with no deaths, strokes, myocardial infarctions, stent thrombosis, and complete stent patency in evaluable subjects.

The prospective, multi-center, single-arm study ran across 11 sites in high-risk patients using the FDA-cleared ENROUTE TCAR neuroprotection system. A PMA supplement for CGuard Prime 80 cm is under FDA review, with potential U.S. approval in H2 2026, targeting over 35,000 annual TCAR procedures.

Analysis

The stock moved -6.0% in the session following this news. A negative reaction despite the 30-day CGUARDIANS II data, featuring 100% acute success and no major adverse events, would fit a pattern where strong clinical signals coexist with broader concerns. Prior disclosures highlighted ongoing net losses and recall-related reserves. The presence of an active S-3 shelf and earlier volatility around news events could have contributed to selling pressure despite the favorable safety profile.

8 terms
pma supplement regulatory
"PMA supplement under FDA review with potential approval in H2 2026"
A PMA supplement is a regulatory filing submitted to the U.S. Food and Drug Administration to request approval for changes to a medical device that already has premarket approval. Think of it like asking permission to alter a trusted product’s recipe, packaging, or manufacturing process; the agency reviews whether the change affects safety or performance. For investors, the outcome influences how quickly a modified product can be sold, the cost and risk of bringing updates to market, and potential sales or liability impacts.
fda regulatory
"PMA Supplement to the U.S. Food and Drug Administration (FDA) which is currently under review"
The FDA is the U.S. federal agency that evaluates and approves medical drugs, devices, biological therapies and certain foods; think of it as the gatekeeper that decides whether a medical product is safe and effective for patients. For investors, FDA decisions determine whether a company can sell a product, affect expected revenue and introduce regulatory risk, so approvals, rejections or safety warnings can quickly move a company's valuation and stock price.
transcarotid artery revascularization (tcar) medical
"CGuard Prime 80cm implant for use in transcarotid artery revascularization (TCAR) procedures"
Transcarotid artery revascularization (TCAR) is a minimally invasive procedure to clear and widen a narrowed carotid artery in the neck that supplies blood to the brain; it uses a small incision to access the artery directly and temporarily reroutes blood through a filter so debris cannot travel to the brain. Investors care because TCAR adoption affects sales of specialized devices, hospital procedure volumes, and reimbursement trends—similar to how a new tool changing construction methods shifts demand in that industry.
stent thrombosis medical
"No stent thrombosis was observed within 30 days"
A stent thrombosis is a blood clot that forms at the site of a metal or mesh tube (stent) placed inside an artery to keep it open; imagine a scaffold in a pipe becoming blocked by debris. It matters to investors because it can cause serious health crises like heart attacks, prompt safety warnings, regulatory scrutiny, legal liability, reduced sales, and changes in reimbursement or clinical adoption that directly affect medical device and healthcare company value.
myocardial infarctions medical
"No deaths, strokes, or myocardial infarctions were reported within 30 days"
Myocardial infarctions are heart attacks caused when blood flow to part of the heart is blocked, damaging heart muscle much like a plumbing clog starves a room of water. They matter to investors because their frequency, available treatments and outcomes drive demand for drugs, devices and hospital services, influence healthcare costs, affect clinical trial results and create potential legal or regulatory risks that can alter a company’s revenue and stock outlook.
carotid endarterectomy medical
"patients considered at high risk for adverse events from carotid endarterectomy"
Carotid endarterectomy is an operation that removes fatty buildup (plaque) from a carotid artery in the neck to restore blood flow to the brain and reduce stroke risk. For investors, it matters because the procedure drives demand for surgical services, medical devices and hospital capacity, affects treatment costs and insurance payouts, and can influence the financial outlook of healthcare providers and makers of related products — like fixing a clogged pipe to prevent a costly flood.
investigational device regulatory
"is an investigational device in the United States and is limited by federal law"
An investigational device is a medical instrument, implant, or tool that is being tested in humans but has not yet received full regulatory approval for general use. Think of it as a prototype on a monitored test drive: investors watch these devices closely because trial results, safety findings, and approval decisions determine whether the product can reach patients, generate revenue, or create regulatory and commercial risk.
pivotal study medical
"CGUARDIANS II is a prospective, multi-center, single-arm pivotal study"
A pivotal study is a large, definitive clinical trial designed to show whether a medical product works and is safe enough for regulators to approve and for doctors to use. Think of it as the final exam that determines whether a drug or device moves from testing into the market; its results can dramatically change a company’s approval chances, future sales prospects, and therefore its stock value.

PMA supplement under FDA review with potential approval in H2 2026, potentially expanding the Company’s addressable market to include TCAR in addition to CAS carotid stenting procedures

MIAMI, June 11, 2026 (GLOBE NEWSWIRE) -- InspireMD, Inc. (Nasdaq: NSPR) (“InspireMD” or the “Company”), developer of the CGuard® Prime carotid stent system for the prevention of stroke, today announced 30-day outcomes from the CGUARDIANS II clinical trial of the CGuard Prime 80cm implant for use in transcarotid artery revascularization (TCAR) procedures. InspireMD anticipates potential approval of the CGuard Prime 80 cm stent implant in the second half of this year.

Key 30-day outcomes observed in the CGUARDIANS II trial include:

  • Acute device success was achieved in 100% (50/50) of patients;
  • No deaths, strokes, or myocardial infarctions were reported within 30 days;
  • No stent thrombosis was observed within 30 days;
  • Complete stent patency observed at 30 days in evaluable subjects.

Dr. Patrick J. Geraghty, professor of surgery and radiology at Washington University School of Medicine in St. Louis and co-lead investigator of the CGUARDIANS II study, commented, “The 30-day results observed in the CGUARDIANS II trial suggest that the CGuard Prime 80 cm stent may deliver exceptional safety and efficacy when used with a TCAR approach. Notably, the 100% acute device success rate with zero major adverse events has the potential to make CGuard Prime the gold standard implant for high-risk patients undergoing TCAR procedures. I look forward to incorporating it into my own practice, if approved.”

“We believe the 30-day CGUARDIANS II results represent a significant achievement in our quest to tap into the large and growing TCAR market,” said Marvin Slosman, CEO of InspireMD. “Together with our recently initiated CGUARDIANS III clinical trial of our proprietary SwitchGuard neuroprotection system, we potentially have line-of-sight to offering the full TCAR toolkit, subject to regulatory review and approval, leveraging our best-in-class CGuard Prime Carotid Stent System with its unmatched clinical outcomes, for the more than 35,000 TCAR procedures that are performed in the U.S. every year.”

CGUARDIANS II is a prospective, multi-center, single-arm pivotal study that enrolled 50 patients across 11 trial sites. The objective of the study is to evaluate acute device success and technical success of the CGuard Prime 80 cm when used in conjunction with the FDA-cleared ENROUTE TCAR neuro-protection system in patients considered at high risk for adverse events from carotid endarterectomy.

Regulatory Disclaimer: The CGuard Prime Carotid Stent System 80 cm is an investigational device in the United States and is limited by federal law to investigational use. InspireMD submitted a Premarket Approval (PMA) Supplement to the U.S. Food and Drug Administration (FDA) which is currently under review.
