Pivotal Study to Evaluate the Safety and Efficacy of GelrinC for Treatment of Cartilage Defects (SAGE)

March 20, 2022 updated by: Regentis Biomaterials

A Prospective, Open-Label, Multicenter Pivotal Study to Evaluate the Safety and Efficacy of GelrinC® for the Treatment of Symptomatic Articular Cartilage Defects of the Femoral Condyle: A Comparison to Historical Control Microfracture

Multicenter, open-label, controlled, non-randomized, double arm trial with a prospective treatment arm (GelrinC). This study compares the efficacy and safety of GelrinC to a historical control arm (microfracture) in the treatment of cartilage defects in the knee.

Study Overview

Status

Status

Active, not recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 50 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

  • Lesion size between 1 and 5 cm2 post debridement, less than or equal to 2.5 cm in diameter.
  • BMI ≤35
  • Contralateral knee is asymptomatic, stable, fully functional and not medically treated.

Main Exclusion Criteria:

  • Presence of an additional grade III or IV symptomatic lesion.
  • Recent Osteochondritis Dissecans within 1 year of baseline visit.

Primary Completion (Anticipated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
