March 8, 2021 updated by: Medical University of Bialystok

Rationale and Design of the Vitamin K2 and Vitamin D3 Intervention Trial in Children and Adolescents With the Low-energy Bone Fractures

a prospective, three- month, randomized, double-blind, placebo-controlled, intervention trial (RDBPC), investigating the effect of vitamin K2 (menaquinone-7) and vitamin D3 on the healing process of low-energy bone fractures in children and adolescents

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

At the admission of patients to the orthopedic outpatient clinic, presence of low- energy fractures will be established based on the anamnesis, physical examination and radiological evaluation. Tests to obtain the baseline blood levels of vitamin D3 will be performed, and only children with vitamin D3 levels lower than 30ng/ml in the blood will be included in the study. The selected population will then be randomly assigned by an independent investigator to the three study groups, receiving daily for three months identical- looking soft gel capsules (1 capsule/patient/day) containing supplements of vitamin D3 2,000 IU, 90 mcg of vitamin K2 as menaquinone-7 combined with 2,000 IU D3, and olive oil-containing placebo capsules respectively. During the 3-month follow-up visits to the outpatient orthopedic clinic, the pediatric orthopedist will examine the patient, evaluate the X-ray, and determine the progress in bone union and the range of joint motion. The patients will visit the clinic on weeks 1,2,4,6,8, and 12. The compliance taking the supplements will be assessed by registering a pill count returned by a patient during the scheduled visit. The blood samples will be collected upon admission to the study, day 0, and after the 3-month regimen. The blood samples will be collected for evaluation of bone turnover markers and the status of vitamin K and vitamin D3. The primary evaluation endpoints will include: the dynamics of fracture healing, changes in levels of osteocalcin, and vitamin K and vitamin D3 levels against the placebo group. The bone fracture healing milestones will be based on bone union defined as the absence of pain and the presence of bridging callus in three of the four cortices seen on the front rear projection and lateral radiographic views of the bone. Delayed union is defined as incomplete consolidation at 90 Days

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

3 years to 18 years (Child, Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Age < 18 years
  • Presence of low-energy fracture

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
