Trial Outcomes & Findings for Effect of Teriparatide Compared to Risedronate on Back Pain in Women With a Spine Fracture Caused by Osteoporosis (NCT NCT00343252)

NCT ID: NCT00343252

Last Updated: 2011-05-26

Results Overview

24-hour worst back pain severity scores recorded daily on an 11-point numeric rating scale, an ordinal scale ranging from 0 (no pain) to 10 (worst possible pain). The 11-point scale is used for assessment of worst back pain in the preceding 24 hours and is evaluated daily in the week prior to each scheduled study visit. Responders are defined as participants with at least a 30% reduction in the severity of worst back pain from baseline to the 6-month last observation carried forward (LOCF) endpoint.

Participant Flow

712 participants were randomized: 361 to teriparatide; 351 to risedronate. 2 participants did not receive drug. Only randomized participants who received at least 1 dose of drug were analyzed. At 18 months, reason for discontinuation was corrected from sponsor decision to entry criteria not met (1) and protocol violation (1) for 2 participants.

PRIMARY outcome

Timeframe: 6 Months

Population: Number of intent-to-treat (ITT) participants who were randomized and received at least one dose of the study drug. Endpoint was on a last observation carried forward (LOCF) basis. Participants with non-missing outcomes were analyzed.

24-hour worst back pain severity scores recorded daily on an 11-point numeric rating scale, an ordinal scale ranging from 0 (no pain) to 10 (worst possible pain). The 11-point scale is used for assessment of worst back pain in the preceding 24 hours and is evaluated daily in the week prior to each scheduled study visit. Responders are defined as participants with at least a 30% reduction in the severity of worst back pain from baseline to the 6-month last observation carried forward (LOCF) endpoint.

Population: Number of intent-to-treat (ITT) participants who were randomized and received at least one dose of the study drug. Participants with non-missing outcomes were analyzed. The results are reported as the number of participants reporting at least a 30% reduction in the severity of back pain after time (t) in days.

Time to first occurrence of \>=30% pain reduction in average back pain from baseline to 6 months. Average back pain is assessed using an 11-point numeric rating scale, an ordinal scale ranging from 0 (no pain) to 10 (worst possible pain), to rate the average back pain experienced in the preceding 24 hours and is evaluated daily in the week prior to each scheduled study visit. The results are reported as the number of participants reporting at least a 30% reduction in the severity of average back pain up to time (t) in days.

Timeframe: Days 0, 60, 120, 180, 240, 300, 360, 420, 480, 540, and 600

Population: Number of intent-to-treat (ITT) participants who were randomized and received at least one dose of the study drug. Participants with non-missing outcomes were analyzed.

Time to first occurrence of \>= 30% pain reduction in average back pain from baseline to 12 months. Average back pain is assessed using an 11-point numeric rating scale, an ordinal scale ranging from 0 (no pain) to 10 (worst possible pain), to rate the average back pain experienced in the preceding 24 hours and is evaluated daily in the week prior to each scheduled study visit. The results are reported as the number of participants reporting at least a 30% reduction in the severity of average back pain up to time (t) in days.

Roland-Morris Disability Questionnaire (RMDQ-24) is completed by the participant and measures the degree of disability due to back pain. The questionnaire consists of 24 statements and the participant is instructed to put a mark next to each appropriate statement. The number of statements marked are added up by the clinician and a total score is given. The total score ranges from 0 (no disability) to 24 (severe disability).

QUALEFFO is an osteoporosis-specific health instrument developed specifically for participants with vertebral deformities used to evaluate the effect of back pain and treatment on quality of life. The QUALEFFO questionnaire includes 41 items in 5 domains: pain, physical function, social function, general health perception, and mental function. The total score is calculated according to the scoring algorithm developed by the International Osteoporosis Foundation. Total scores are reported from 0 to 100, with lower scores corresponding to better quality of life.
