Cholecalciferol Supplementation in Strengthening Inspiratory Muscles in Cholecalciferol-Deficient Patients With Chronic Obstructive Pulmonary Disease

February 14, 2017 updated by: Roswell Park Cancer Institute

Effect of Once Daily Oral Vitamin D3 Supplementation on Inspiratory Muscle Strength in Vitamin D3-Deficient COPD Patients

This phase IIb randomized trial studies how well cholecalciferol (vitamin D3) supplementation works in strengthening inspiratory muscles in cholecalciferol-deficient patients with chronic obstructive pulmonary disease (COPD). Cholecalciferol supplementation may help reduce the risk of developing lung cancer and strengthen the diaphragm in cholecalciferol-deficient patients with COPD.

Study Overview

Detailed Description

PRIMARY OBJECTIVES:

I. To establish the effect of D vitamin (vitamin D3) supplementation on inspiratory muscle strength in vitamin D3-deficient chronic obstructive pulmonary disease (COPD) patients. (Roswell Park Cancer Institute [RPCI]/University at Buffalo [UB] study) II. To establish the 12 month conversion rate. (University of Pittsburgh Cancer Institute [UPCI] study)

SECONDARY OBJECTIVES:

I. To establish the effect of vitamin D3 supplementation on peripheral muscle strength and exercise capacity in vitamin D3-deficient COPD patients. (RPCI/UB study) II. To establish the 3 and 6-month conversion rates. (UPCI study) III. To examine whether vitamin D3 supplementation is equally effective in COPD patients who are current versus former smokers. (UPCI study)

TERTIARY OBJECTIVES:

I. To explore the effects of vitamin D3 supplementation in COPD patients on biomarkers of lung cancer risk, inflammation, and pulmonary function. (UPCI study)

OUTLINE: Patients are randomized to 1 of 2 arms.

CONTROL ARM: Patients receive a placebo and multivitamin orally (PO) once daily (QD) for 52 weeks.

SUPPLEMENTATION ARM: Patients receive a multivitamin and cholecalciferol supplement PO QD for 52 weeks.

After completion of study treatment, patients are followed up for 1 year.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Conversion rate, defined as the proportion of patients whose baseline cholecalciferol deficiency is corrected (UPCI study)
Time Frame: At 12 months
75% will be considered a success.
At 12 months
Inspiratory muscle strength assessed by respiratory capacity (RPCI/UB study)
Time Frame: Baseline to 24 weeks
Will be analyzed using linear mixed model by regressing the repeated outcome on the group indicator (treatment or control) and other appropriate covariates. Appropriate within-subject covariance will be determined from an exploratory study. The effect of vitamin D3 supplementation will be tested using an approximate t-test.
Baseline to 24 weeks

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in exercise capacity assessed by respiratory exercise tests (RPCI/UB study)
Time Frame: Baseline to 24 weeks
Peak oxygen consumption will be used to establish cardiovascular fitness. Breath-by-breath measurements of minute ventilation, tidal volume, breathing frequency, end tidal carbon dioxide, carbon dioxide production and oxygen consumption will be continuously measured.
Baseline to 24 weeks
Change in peripheral muscle strength assessed by the elbow flexion test (RPCI/UB study)
Time Frame: Baseline to 24 weeks
The elbow flexion test (upper extremity) requires participants to curl a standard 8 lb weight as many times as possible in a 30 second time period.
Baseline to 24 weeks
Conversion rate, defined as the proportion of patients whose baseline cholecalciferol deficiency is corrected (UPCI study)
Time Frame: At 3 months
Efficacy in in COPD patients who are current versus former smokers will be compared.
At 3 months
Conversion rate, defined as the proportion of patients whose baseline cholecalciferol deficiency is corrected (UPCI study)
Time Frame: At 6 months
Efficacy in in COPD patients who are current versus former smokers will be compared.
At 6 months
Change in peripheral muscle strength assessed by squat test (RPCI/UB study)
Time Frame: Baseline to 24 weeks
This functional sit-to-stand test measures lower extremity strength. Participants will perform as many sit-to-stand repetitions from a standard height chair in 60 seconds as possible.
Baseline to 24 weeks

Other Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in correlative biomarkers of lung cancer risk, inflammation, and pulmonary function (UPCI study)
Time Frame: Baseline to up to 1 year
The vitamin D3 supplementation group will be compared to the placebo control group using two-sample t-tests at each time point for preliminary analysis. The correlation between muscle strength and the correlative biomarkers will be explored using Pearson correlation.
Baseline to up to 1 year
