Intervention(s):

Experimental group: Usual medical care plus Bioactive Formulation (patents US 9089580 B1 and US 9669074 B2). Patients will have usual treatment prescribed by their family physician, within their routine consultations in their health system. It consists of paracetamol or/and nonsteroidal anti-inflammatory drugs use and the promotion of a healthy lifestyle. The researchers will not intervene in relation to drug prescription or lifestyle indications. Additionally, patients will receive a intra-articular application of the solution called bioactive formulation into affected joint. The amount applied varies according to the joint: 2ml for knee or hip, 1.5ml for shoulder and 0.5ml for the mandibular joint. The intra-articular application is performed on an outpatient basis and it is repeated at 60 and 120 days for one subgroup or after 30 and 60 days, for another subgroup. Control Group: Usual medical care. Patients will have usual treatment prescribed by their family physician, within their routine consultations in their health system.

Outcomes and Timepoint

Section to complete information about primary and secondary outcomes including. It includes the metric or method of measurement used and, the time point for every outcome.

Primary outcome(s):

Therapeutic efficacy: 1) Minimal Clinically Important Improvement-MCII (defined as the smallest change in measurement that signifies an important improvement in a patient’s symptom (VAS, WOMAC, Clinical Rasmussen, RAPID3). It will be calculated through a dichotomous score per outcome, based on 30% improvement from the baseline). Measurement time: baseline, at 90, 180 and 360 days. 2) Patient Acceptable Symptom State-PASS (defined as the value of symptoms the patient considers to be the thresholds of well-being for pain and function. This will be assessed with the following question: “Taking into account all your daily activities, do you consider your current state satisfactory in relation to pain level and functional impairment?” The response options are “Yes” or “No”). Measurement time: baseline, at 90, 180 and 360 days.

Key secondary outcomes:

1) Adverse Events (According to Common Terminology of Criteria for Adverse Events (CTCAE) version 3. Bone necrosis or tissues adjacent to the lesion, bone or muscle changes not compatible with a normal anatomy, muscle weakness, nausea, skin atrophy, ecchymosis, changes in skin pigmentation, fibrosis , alterations in the state of consciousness, pain in the area of application, neurological events, alterations in the liver enzymes or blood count, bone fracture, cardiovascular events). Measurement time: baseline, at 30, 90, 180 and 360 days. 2) Change in anti-inflammatory non steroidal drugs use. Measurement time: baseline, at 90, 180 and 360 days.
