Efficacy and Safety of b-2Cool on Adults With Joint Discomfort

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: NCT02843620

Brief Summary:
This study evaluates the effects of 40 mg of b-2Cool, a food supplement rich in native type-II collagen, on healthy adults with joint discomfort. Half of the participants will receive the b-2Cool containing supplement while the other half will receive a placebo pill.

Condition or disease Intervention/treatment Phase
Joint Discomfort Dietary Supplement: b-2Cool Other: Placebo Not Applicable

Detailed Description:

Previous studies had shown the efficacy of the intake of native collagen to relieve pain in healthy patients with joint discomfort.

Native collagen is detected in the gut's Peyer's patches and, thanks to a mechanism known as oral tolerisation, reduces the autoimmune attack to joints' collagen improving joint function and pain.

Oral tolerance consists of two phases of immune response: the maintenance of homeostasis and the suppression of immune responses mediated by Ag-specific regulatory T cells. T-cells detect the epitopes of type-II collagen in the gut and suppress the immune response against bodily type-II collagen. Then, these regulatory T cells generated in the gut are presumed to migrate to a local microenvironment where a protein analogous to the orally dosed antigen resides, in this case type-II collagen. Upon reactivation in a new microenvironment, regulatory cells will suppress ongoing inflammation.

Primary Outcome Measures :
  1. Change from baseline of ultrasonographic assessment of synovial effusion [ Time Frame: 0, 6, 12 and 24 weeks ]

Secondary Outcome Measures :
  1. Visual Analog Scale (VAS) pain evaluation [ Time Frame: 0, 6, 12 and 24 weeks ]
  2. WOMAC Functional assesment [ Time Frame: 0, 6, 12 and 24 weeks ]
  3. Subjective evaluation of quality of life [ Time Frame: 0, 6, 12 and 24 weeks ]
    Patients will report some aspects of their Quality of life through Visual analogic scales

  4. Collagen degradation markers in urine [ Time Frame: 0, 12 and 24 weeks ]
  5. Patient's satisfaction [ Time Frame: 6, 12 and 24 weeks ]
    Patient satisfaction will be evaluated using a subjective questionnaire

  6. Rescue medication consumption [ Time Frame: Every 2 weeks for 24 weeks ]
  7. Adverse events [ Time Frame: 6 months ]
