Trial Outcomes & Findings for Neurotropin Treatment of Fibromyalgia (NCT NCT00366535)

NCT ID: NCT00366535

Last Updated: 2018-06-27

Results Overview

The Fibromyalgia Impact Questionnaire (FIQ) is a brief 10-item self-administered measure to assess 3 areas of fibromyalgia (FM): function, overall impact, and symptoms. The total FIQ score was the primary outcome of the study. The total FIQ score is the sum of the 3 areas measured in the FIQ. The maximum possible total FIQ score is 100, with a minimum score of 10. The average FM patient scores about 50, severely afflicted FM patients are usually 70 and above. Data analysis is ongoing from data collected from study completers.

Participant Flow

Most patients were recruited by direct physician referral or through the Patient Recruitment and Public Liaison (PRPL) office. Potential subjects were screened for study eligibility at the NIH Clinical Center.

Patients with abnormal screening laboratory tests or had positive HIV test were excluded from study participation. Women who had positive urine pregnancy test were also excluded. Also patients with traumatic or non-traumatic pain disorders or had neurocognitive impairment making it challenging to obtain informed consent, were also excluded.

Double blind cross-over study: received Placebo (4 tabs, b.i.d.) for 12 weeks and then Neurotropin (4 tabs, b.i.d.) for 12 weeks (after at least 1 week washout period). Assignment to each group was randomized by the NIH Clinical Center pharmacy. Study team and participants were all blinded.

PRIMARY outcome

Timeframe: 25 weeks

Population: Total 56 patients enrolled, and 39 patients completed the study. 17 patients withdrawn from the study. Three of 39 patients were excluded from the data analysis because there had missing FIQ scores at Baseline and/or Week 12. The data from the study of the 36 participants with complete data sets was analyzed.

The Fibromyalgia Impact Questionnaire (FIQ) is a brief 10-item self-administered measure to assess 3 areas of fibromyalgia (FM): function, overall impact, and symptoms. The total FIQ score was the primary outcome of the study. The total FIQ score is the sum of the 3 areas measured in the FIQ. The maximum possible total FIQ score is 100, with a minimum score of 10. The average FM patient scores about 50, severely afflicted FM patients are usually 70 and above. Data analysis is ongoing from data collected from study completers.
