Clinical Trial Summary

This study aims to evaluate the safety and analgesic effect (efficacy) of Gastrolith powder (GASP) on skeletal pain caused by osteoporotic vertebral compression fractures (OVCF) versus placebo, primarily as assessed by the Numeric Rating Scale (NRS), and Brief Pain Inventory (BPI). It is also intended to evaluate disability change with the Oswestry Low Back Pain Disability Index (ODI) and to evaluate whether GASP consumption leads to reduction in analgesic standard of care (ASOC) versus placebo, using weekly analgesic consumption diaries.

Description:

Eighty (80) Osteoporotic subjects with recent reported severe back pain caused by OVCF will be blindly randomized into two groups (n=40 each). One group will receive GASP and the other Placebo. The analgesic effect of GASP on top of the ASOC will be evaluated using weekly NRS and BPI assessments and three ODI questionnaires. Daily ASOC consumption will be monitored using weekly analgesic consumption diaries.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Reduction of pain assessed by change in NRS from baseline to end of the trial	• Change from baseline to end-of-trial on NRS during movement (scale of 0 to 10) computed as follows.; NRSchange = NRS42 - NRS0 NRS42 - NRS score at day 42 (end-of-trial) NRS0 - NRS score at day 0 (baseline)	from baseline to end of the trial
Secondary	Reduction of pain assessed by change in BPI from baseline to end-of-trial	The BPI uses 0 to 10 numeric rating scales for item rating because of its simplicity, lack of ambiguity and seemed the best to use for cross-linguistic pain measurement. Since pain can be quite variable over a day, the BPI asks subjects to rate their pain at the time of responding to the questionnaire (pain now), and also at its worst, least, and average over the previous week. The ratings can also be made for the last 24 hours.	baseline to end-of-trial
Secondary	Reduction of disability assessed by change in ODI from baseline to end-of-trial	Oswestry Low Back Pain Disability Questionnaire - comprises of 10 sections describing the pain and its impact, each scored from 0 to 5 with higher values indicating more severe impact.	baseline to end-of-trial
Secondary	Reduction of ASOC assessed by weekly change in analgesic consumption diaries from baseline to end of trial	Analgesic drug consumption will be daily self-recorded by subjects in a diary bearing drug's name and daily dose. The number of tablets taken each day will be noted in each category.	baseline to end of trial
Secondary	All adverse events and serious adverse events will be collected and reported	An adverse event is any untoward medical sign (including an abnormal laboratory finding), symptom or disease temporally associated with the use of the IPs whether or not considered as IP related. A new condition or the worsening of a pre-existing condition will be considered an AE. All abnormal findings considered to be clinically significant must be recorded as adverse events	Baseline until four (4) weeks after completion of the study.
