Efficacy and Tolerability of a Nutritional Supplement, Plactive Progen, in ACL Reconstruction

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT03355651
Recruitment Status : Completed
First Posted : November 28, 2017
Last Update Posted : November 30, 2017
Information provided by (Responsible Party):
OPKO Health, Inc.

Brief Summary:
This was a prospective, multicenter, randomized, open-label, phase IV trial to compare the efficacy of supplementation with plasma proteins, hydrolyzed collagen (CH), a complex of HA-CS (HC-15), and vitamin C combined with a standard rehabilitation protocol versus the standard rehabilitation protocol only after arthroscopically-assisted functional ACL reconstruction with hamstrings.

Arm Intervention/treatment
Active Comparator: PROGEN Group
PROGEN + Standard Rehabilitation + ACL reconstruction
Dietary Supplement: PROGEN
Dietary supplement based on plasma proteins, hydrolyzed collagen, a complex of Hyaluronic Acid - Chondroitin Sulfate (HC-15), and vitamin C

No Intervention: Control Group
Standard Rehabilitation + ACL reconstruction

Primary Outcome Measures :
  1. Pain improvement [ Time Frame: 90 days ]
    Assessed using a 100-mm Visual Analog Scale (VAS)

Secondary Outcome Measures :
  1. Knee function [ Time Frame: 90 days ]
    Assessed using the International Knee Documentation Committee (IKDC) index. The final score was interpreted as a measure of function, with higher scores representing higher levels of function

  2. Analgesic consumption [ Time Frame: 90 days ]
    Analgesic consumption and frequency of analgesic intake during follow-up

  3. Number of rehabilitation sessions required [ Time Frame: 90 days ]
    Number of required rehabilitation sessions at the end of follow-up.

  4. Maduration of the graft [ Time Frame: Day 0, day 90 ]
    Assessed by MRI, by a single blind muskuloskeletal radiologist, using a standard procedure based on ACL oblique parasagittal T1 sequences

Other Outcome Measures:
  1. Perceived efficacy and tolerability by both patients and physicians [ Time Frame: 90 days ]
    Perceived efficacy and tolerability were rated by both patients and physicians on a 5-point Likert scale, where higher scores indicated better efficacy and tolerability

  2. Safety [ Time Frame: 90 days ]
    Assessed by means of all adverse events (AE) treatment related, reported at the end of follow-up.

Ages Eligible for Study:   18 Years to 55 Years   (Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Subjects aged between 18 and 55 years with partial or complete anterior cruciate ligament (ACL) rupture, diagnosed clinically and by Magnetic Resonance Imaging (MRI), requiring reconstructive surgery.
  • Patients with symptoms of acute or subacute ACL rupture (such as inflammation of the knee and pain with leg movement) or chronic ACL tear, including instability of the knee.
  • Patients with ACL ruptures without osteochondral lesions requiring additional surgery.
  • Patients with a medical history of therapeutic benefit using analgesic agents.

Exclusion Criteria:

  • Patients with concomitant osteochondral pathology.
  • Patients treated with intra-articular injections of corticosteroids and/or platelet-rich plasma, or with oral glucosamine, CS, HA or CH in the two months prior to surgery.
  • Patients with systemic diseases, those treated with antibiotics or other drugs that might alter the healing process, and those who had undergone arthroscopic lavage in the 90 days prior to surgery.
