Eleven U.S. Sites Now Enrolling People with Knee Pain
Caused by Damaged Articular Cartilage
PRINCETON, NJ and OR AKIVA, Israel – October 23, 2018 – Regentis Biomaterials today
announced it has expanded the SAGE clinical trial of
GelrinC™ for the treatment of articular
cartilage damage in the knee to 11 U.S. sites. GelrinC is an investigational device being evaluated
as a treatment to help the body regrow cartilage in the knee.
Articular cartilage is the smooth, white tissue covering the ends of bones where they come
together to form joints. Damage to the cartilage layer can be extremely painful for patients and
is generally associated with sudden trauma. Surgical intervention is often required because of
the limited capacity for cartilage to repair itself. The current standard of care is called
microfracture, which involves drilling small holes in the underlying bone to allow a blood clot to
form within the defect. However, microfracture often provides only short-term relief and may
require repeat surgeries.
“Cartilage repair is the largest unmet need in orthopedic sports medicine today,” said Alastair
Clemow, Ph.D., president and CEO, Regentis Biomaterials. “GelrinC enables patients to harness
the benefits of their own stem cells to promote cartilage regeneration in a single, minimally
invasive procedure.”
People with knee pain caused by damaged articular cartilage who would like to be considered
for the study can inquire by visiting or by calling (833) 430-8686.
The following orthopedic centers are currently or will soon be recruiting patients, with
additional sites to be added soon in Denver, Colorado; San Francisco, California; Orlando,
Florida; and Portland, Oregon.

About the SAGE Clinical Trial
The SAGE study is a Food and Drug Administration (FDA) Investigational Device Exemption (IDE)
clinical study comparing GelrinC to microfracture, the current standard of care treatment for
damaged knee cartilage. The multi-center Phase III pivotal study will enroll 120 patients. All
patients who meet study requirements and agree to enter the trial are provided GelrinC as
treatment, and their results will be compared to raw level historical data of a microfracture
control arm. To be eligible for the study, participants must be between the ages of 18 and 50

and have pain caused by cartilage damage in only one knee. To learn more about the SAGE
study, please visit or call (833) 430-8686.
About GelrinC™
In the U.S., GelrinC™ from Regentis Biomaterials is an investigational device for patients with
articular cartilage damage in their knee. GelrinC is composed of a synthetic material called
polyethylene glycol (PEG) and a structurally modified form of human fibrinogen, a protein which
in its native form assists healing processes. PEG and native human fibrinogen have been used
individually in medical products for many years with excellent results. GelrinC’s unique mode of
action relies upon its ability to be implanted as a liquid so that it completely fills the defect, and
then be cured into a gel that enables the body’s own stem cells to settle on its surface. Over a
period of six to 12 months, the GelrinC is gradually resorbed by the body and replaced by new
cartilage tissue. Preliminary clinical trials in Europe have indicated that this regenerated tissue
provides excellent improvement in pain and function. To learn more about GelrinC, please visit
