In Vivo Osteoinduction: Evaluating 2-Beta Coxatene as an Immunoinductive Compound and Novel Ingredient for Joint Support.

contextOsteoarthritis (OA) is a degenerative joint disease characterized by progressive loss of articular cartilage. Many treatments lack the ability to stimulate the growth of native cartilage tissue while they simultaneously increase joint comfort. For the past few decades, dietary supplements have been investigated for the ability to both address joint inflammation and stimulate cartilage tissue.

objectivesThe present study intended to examine the supplement's in vivo osteoinductive capabilities and clinical efficacy for overall joint health.

designThe research team designed a randomized, double-blind, comparative clinical trial.

settingThe study took place via telephone interviews.

participantsParticipants had self-reported OA of a weight-bearing joint (ie, of the knee, hip, spine, or ankle). Patients were recruited using the Health Science Institute, a consumer supplement newsletter.

interventionParticipants in the intervention group were blindly given 135 mg of 2-Beta Coxatene (2BCT) orally, which contained (1) a custom blend of low-dose Cyplexinol, an osteoinductive protein complex derived from bovine bone tissue, and (2) OUTCOME MEASURES: A histological evaluation was performed on an athymic rat to test the supplement's in vivo osteoinductive capabilities. A negative control, commercially purchased, unhydrolyzed type 2 collagen was used for that test. Participants were evaluated for parameters of pain and joint function at baseline (day 0) and at days 7, 30, and 90 using the Western Ontario and McMaster Universities (WOMAC) OA index and a visual analogue scale (VAS).

resultsThe histological evaluation of the athymic rat confirmed that the Cyplexinol component of the 2BCT was positive for de novo bone tissue and collagen synthesis, corroborating osteoinduction. In the clinical trial, the intervention group reported significant decreases of 57.4%, 52.5%, and 58% in normalized WOMAC scores for pain, stiffness, and joint functionality, respectively, from baseline to postintervention. The control group reported a decrease of 17.5%, 18.1%, and 23.9% for pain, stiffness, and joint functionality, respectively. For the intervention group, pain intensity and frequency, as measured by the VAS, also decreased 57.1% and 56.3%, respectively, from baseline to postintervention, whereas the control group showed a decrease in VAS scores of 18.0% and 14.8%, respectively. In total, an average of 81.2% of participants administered the 2BCT had reported a statistically significant improvement from baseline to postintervention, compared with 22.9% of participants administered glucosamine and chondroitin.

conclusionsIn vivo studies confirmed that the bioactive proteins (Cyplexinol) within the 2BCT stimulated de novo bone and cartilage tissue production, demonstrating osteoinduction. The intervention group reported greater improvements in the psychometric evaluations that assessed joint comfort when compared with participants given the glucosamine and chondroitin. The results suggest that 2BCT may provide a novel and synergistic response to preserving joint homeostasis and improving quality of life.
