First patient enrolled in feasibility trial for JuxtaFlow® Renal Assist Device (RAD)

Roswell, Georgia – 9 October, 2023 – Roivios Ltd., a medical device company pioneering a
revolutionary treatment to reduce poor surgical outcomes associated with Acute Kidney Injury
(AKI), today announces the first patient has been enrolled in the BIPASS-AKI early feasibility
study for the JuxtaFlow Renal Assist Device (RAD). Insertion of the proprietary JuxtaFlow
catheters was overseen by principal investigators Prof. Slobodan Micovic and Dr Dragana
Kosevic from the Institute for Cardiovascular Diseases Dedinje in Belgrade, Serbia.

“This is an exciting moment for patients with renal insufficiency who undergo cardiac surgery,”
said Prof. Micovic “These individuals frequently develop post-surgical complications and
become some of our most challenging and complex patients, so I am proud to be the first to
offer this novel therapy in the study.” Cardiac surgery-associated AKI (CSA-AKI) occurs in up to 73% of patients who have preexisting renal insufficiency documented as part of their standard pre-surgical workup.

This type of AKI then impacts a patient’s ability to recover from surgery, leading to a longer and more
costly hospital stay, a higher risk of morbidity and mortality, and a more frequent need for
chronic dialysis treatment. The JuxtaFlow RAD is used in the hospital setting where it
enables the kidneys to function optimally and thereby improve overall patient outcomes.

“Patients who develop AKI after cardiac surgery have few options. This unmet clinical need has
driven the team at Roivios to design an innovative solution that enhances the kidneys’ own
natural ability to function without altering the patient’s hemodynamic status in any way.”, said
John Erbey, PhD, Chief Executive Officer of Roivios. “We are incredibly excited about the
opportunity to apply this novel therapy to at-risk patients and serve as the bridge to their
successful recovery. We look forward to partnering with hospitals, surgeons, and critical care
teams around the world who share our vision for reducing this all-too-frequent adverse event of

The BIPASS feasibility trial is being conducted pursuant to Medicines and Medical Devices
Agency of Serbia (aka ALIMS) regulations. Ten patients will be enrolled across two hospitals in
Serbia, one located in the capital of Belgrade and the other in the city of Sremska Kamenica. Regulatory submissions and comprehensive study operations oversight will be provided by SCIRENT Clinical Research & Science, a specialty cardiovascular CRO with offices in Belgrade and Berlin.

“We are very excited to lead the study operations for this groundbreaking JuxtaFlow® Renal Assist Device for Roivios, Ltd..” said Prof. Hans-Dirk Duengen, Chief Executive Officer of SCIRENT. As a contract research organization, SCIRENT specializes in cardiovascular trials, with a specific focus on medical device trials.

The JuxtaFlow RAD is not commercially available in any geography. The system is limited by
United States law to Investigational Use Only and is not available for sale in the United States.
