A Clinical Trial Investigating the Effect of Salmon Bone Meal on Bone Mass Among Osteopenic Women

Hofseth Biocare ASA80 enrolled

Overview

The purpose of this study is to evaluate the efficacy of salmon bone meal in preventing bone loss among perimenopausal women with reduced bone mass density.

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 effect of salmon bone meal on bone mass density among perimenopausal women (age ≥ 50 years) with osteopenia is investigated over a time period of 2 years. Salmon bone meal is composed of a natural microcrystalline hydroxyapatite form of calcium and phosphorus, collagen type 2. Past literature on mammalian sources of bone meal has indicated that this form of calcium is superior in terms of preserving bone mass density compared to traditional calcium supplements. Preserving bone mass is essential to reduce the risk of future fragility fractures. Osteopenia is a condition of reduced bone mass density and bone quality which can indicate the later onset of clinical osteoporosis. Both are conditions associated with a significant risk of fragility fractures, which are a major global health burden. Bone mass density is measured using dual-energy X-ray absorptiometry. Markers of bone formation P1NP and CTX-1 will be measured in serum samples of participants. 100 potential participants will be screened for eligibility. Participants who meet the eligibility criteria will be randomized in a double-blind manner to receive 4 capsules daily of salmon bone meal enriched with Vitamin D3 per capsule.

Outcomes

Primary Outcomes

Mean change in Bone Mass Density (BMD) of the femoral neck at Month 12, and Month 24.

Change in BMD of the femoral neck is assessed based on dual-energy X-ray absorptiometry T-scores.

Time frame: Baseline, 12 Months, and 24 Months.

Secondary Outcomes

Mean change in Bone Mass Density (BMD) of the lumbar spine (L1-L4) at Month 12, and Month 24.

Change in BMD of the lumbar spine segments L1-L4 is assessed based on dual-energy X-ray absorptiometry T-scores.

Time frame: Baseline, 12 Months, and 24 Months

Mean change in Bone Mass Density (BMD) of the distal forearm at Month 12, and Month 24.

Change in BMD of the distal forearm (distal radius) is assessed based on dual-energy X-ray absorptiometry T-scores.

Time frame: Baseline, 12 Months, and 24 Months

Change in serum levels of markers of bone formation at Month 6, Month 12, and Month 24.

Serum markers of bone formation are analyzed in frozen serum samples from participants.

Time frame: Baseline, 6 Months, 12 Months, and 24 Months.

Change from Baseline in self-assessed quality of life on the EuroQol-5 Dimensions-3 Levels (EQ-5D-3L) instrument at Month 24.

5Q-5D-3L is a standardized instrument used to measure generic quality of life based on five distinct dimensions. EQ-5D-3L contains two parts. The first part contains five questions that the individual must answer and includes mobility (walking), self-care, usual activities, pain/discomfort, and anxiety/depression. For each item, there are three possible answers. Results are reported as a five-digit number ranging from 11111 (best health status) to 33333 (worst health status). Several methods exist for analysing these number profiles, and it is possible to convert the number profile into an index number. The second part is the EQ-VAS, where the patient self-assesses their overall health on a visual analogue scale (VAS), with 100 indicating the best health status.
