Trial Outcomes & Findings for High Dose Vitamin D vs Standard Dose Vitamin D Study (NCT NCT01988090)

NCT ID: NCT01988090

Last Updated: 2021-08-09

Results Overview

Aromatase Inhibitor Arthralgia (AIA) was assessed by a questionnaire that describe the level of pain experienced by the participant. The questionnaire asks 20 questions scored 0-3 in 8 categories of functioning: dressing, rising, eating, walking, hygiene, reach, grip, and usual activities. An average composite score on the HAQ-II was calculated. The visual analog scale is the other major component of the HAQ-II, which we ask patients to mark where their pain lies on a horizontal line and we converts the number into a score from 0 to 3. For the purposes of this study, AIA will be defined as any of the following criteria: 1) increase in HAQ-II score from baseline by 0.2 or greater; or 2) increase in visual analog pain score by 0.3 or greater.

PRIMARY outcome

Timeframe: 12 weeks

Population: ITT population. All patients who were randomized in the study were included in the overall evaluation of response (intent-to-treat analysis).

Aromatase Inhibitor Arthralgia (AIA) was assessed by a questionnaire that describe the level of pain experienced by the participant. The questionnaire asks 20 questions scored 0-3 in 8 categories of functioning: dressing, rising, eating, walking, hygiene, reach, grip, and usual activities. An average composite score on the HAQ-II was calculated. The visual analog scale is the other major component of the HAQ-II, which we ask patients to mark where their pain lies on a horizontal line and we converts the number into a score from 0 to 3. For the purposes of this study, AIA will be defined as any of the following criteria: 1) increase in HAQ-II score from baseline by 0.2 or greater; or 2) increase in visual analog pain score by 0.3 or greater.

SECONDARY outcome

Timeframe: 52 Weeks

Population: Compliance was assessed at week 52. Only 14 patients have compete the data collection. Form was not completed due to not starting the treatment, or not finishing the treatment, or no source data.

We checked compliance of aromatase inhibitor therapy during the study by reviewing the patient's use of AI drug. This will be done by counting remaining pills in patient's bottles of AI at 52 weeks. A percentage of the number of pills were actually taken of the number of pills should be taken was calculated.
