Inari Medical Announces Randomized Controlled Trial Evaluating Clinical Outcomes of the ClotTriever® System in Deep Vein Thrombosis

Rhea-AI Summary

Inari Medical (NASDAQ: NARI) announced the upcoming enrollment of the DEFIANCE trial, a randomized controlled study aimed at assessing the effectiveness of the ClotTriever System for treating iliofemoral deep vein thrombosis (DVT) compared to traditional anticoagulation therapy. This trial will involve 300 patients across 60 centers globally. DEFIANCE is expected to set new treatment standards and reduce post-thrombotic syndrome risks. It follows the PEERLESS trial, further bolstering Inari's commitment to pioneering clinical research in vascular treatments.

Positive

• Enrollment of 300 patients in the DEFIANCE trial signals strong commitment to clinical research.
• Potential to set new treatment standards for DVT and reduce risks of post-thrombotic syndrome.
• DEFIANCE trial follows PEERLESS, indicating a robust clinical study framework.

Negative

• None.

IRVINE, Calif., Aug. 30, 2022 (GLOBE NEWSWIRE) -- Inari Medical, Inc. (NASDAQ: NARI) (“Inari”) a medical device company with a mission to treat and transform the lives of patients suffering from venous and other diseases, announced planned enrollment of the DEFIANCE trial.

DEFIANCE is a randomized controlled trial (“RCT”) comparing the clinical outcomes of patients with iliofemoral deep vein thrombosis (“DVT”) treated with the ClotTriever System versus anticoagulation only. The trial will enroll 300 patients at up to 60 centers worldwide. DEFIANCE is Inari’s second RCT and it will run in parallel to the PEERLESS trial. PEERLESS commenced earlier this year and compares FlowTriever to catheter-directed thrombolytics in pulmonary embolism.

“Anticoagulation is still the predominant therapy used in the management of DVT and in some studies has been associated with post-thrombotic syndrome (PTS) in up to 50% of patients,” said Dr. Steven Abramowitz, Co-Principal Investigatory and Chair of Vascular Surgery at MedStar Heath. “PTS is a debilitating condition with symptoms including swelling, difficulty walking, skin changes and poorly healing open wounds. Research has shown PTS quality of life scores can be as low as those of patients suffering from heart failure or cancer. Mechanical thrombectomy procedures, using technology like ClotTriever, rapidly remove large volumes of DVT and may thereby reduce the risk of PTS.”

“DEFIANCE is the first RCT to compare mechanical thrombectomy to anticoagulation for the treatment of DVT,” said Dr. Xhorlina Marko, Co-Principal Investigator and Interventional Radiologist at Beaumont Health. “The primary endpoint for the trial is a hierarchical composite of treatment failure and PTS severity at 6 months. The trial has the potential to influence guidelines and change the standard of care.”

“Physicians need to know in which patients to use our devices and what outcomes to expect. This is our basic responsibility,” said Dr. Thomas Tu, Inari’s Chief Medical Officer. “We have studied over 2,000 patients, published 250 peer reviewed publications, and DEFIANCE marks our 6^th major clinical study. These high-quality studies will establish a new standard of care for patients and further distance us from competition.”
