A Clinical Trial Investigating the Effect of Salmon Bone Meal on Osteoarthritis Among Men and Women

Hofseth Biocare ASA98 enrolled

Overview

The purpose of this study is to evaluate the efficacy of hydrolyzed collagen in osteoarthritis.

The current study is part of a larger project called the CalGo-project. The overall purpose of the study is to use bone meal from salmon to promote skeletal health. Specifically, the potential for hydrolyzed collagen type II derived from salmon bone meal in ameliorating pain, stiffness and function in participants diagnosed with osteoarthritis will be evaluated over a time period of 6 months. Past literature indicates that collagen derivatives may be a potential supportive strategy in people suffering from osteoarthritis. Osteoarthritis is a common but complex joint disease with significant unmet medical needs, as there are currently no disease-modifying drugs available. Osteoarthritis represents a global health burden and the only curative treatment when pain becomes unmanageable, is joint replacement. The dimensions of pain, stiffness, and function will be evaluated using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC 3.1). Plain x-rays with Kellgren-Lawrence grading will be employed to classify the severity of osteoarthritis. 100 potential participants will be screened for eligibility. Participants who meet the eligibility criteria will be randomized in a double-blind manner to receive 10 capsules daily of hydrolyzed collagen type II (a total of 5000 mg), 10 capsules daily of salmon bone meal, or 10 capsules daily of placebo.

Outcomes

Primary Outcomes

Mean change from Baseline in WOMAC composite score at Month 3 and Month 6.

A change in osteoarthritis symptomatology is assessed using a disease specific questionnaire (WOMAC 3.1).

Time frame: Baseline, 3 Months, and 6 Months

Secondary Outcomes

Mean change from from Baseline on the WOMAC pain subscale at Month 3 and Month 6.

Pain is evaluated using the pain dimension of WOMAC 3.1, a disease-specific questionnaire. The pain subscale includes 5 items that assesses pain intensity. A score is produced when the value of each item is summarized. A higher score indicates worse pain.

Time frame: Baseline, 3 Months, and 6 Months

Change from Baseline on an 11-point likert Global Assessment Scale at Month 3 and Month 6.

A GAS scale gives an overall picture of an individuals' self-assessed effect of treatment. The individual is asked to compare the present health status with their health status at a previous point in time. The magnitude of this difference is scored numerically. In this study, we will use GAS on a 11-point Likert rating scale ranging from "completely recovered" to "worse than ever", with 0 being "unchanged" status.

Time frame: Baseline, 3 Months, and 6 Months

Change from Baseline in pain intensity on a Numerical Rating Scale at Month 3 and Month 6.

In this study, we will employ an 11-point (i.e., 0 to 10) Numerical Rating Scale as was recommended for use in chronic pain trials according to 2005 IMMPACT guidelines. 0 represents "No pain", and 10 represents "The most intense pain imaginable".

Time frame: Baseline, 3 Months, and 6 Months

Change from Baseline in number of rescue medications self-administered during the study period.

Rescue medications that participants may use on an as needed basis include Paracetamol, typical NSAIDs, and analgesics containing opioids.
