About this study

Official title: Randomized, Double-Blind, Double-Dummy Trial of Two Sustained Release Formulations of Carisoprodol Compared to Placebo in Subjects With Acute, Painful, Musculoskeletal Spasm of the Lower Back

The purpose of this study is to determine if two sustained released formulations of carisoprodol are more effective than placebo.

Read the detailed description

Methodology:

This was a randomized, double-blind, double-dummy, placebo-controlled, parallel-group study in subjects 18-70 years of age with acute, painful, muscle spasm of the lower back. The study consisted of a baseline screening (Study Day 1), during which subjects were evaluated for inclusion/exclusion criteria, and a 7-day double-blind treatment period (Study Day 1 through Study Day 7). Subjects were randomly assigned to be dosed twice daily with one of the following double-blind treatments: sustained release(SR) carisoprodol 500-mg tablets,sustained release (SR) carisoprodol 700-mg tablets, or placebo.

Subjects were evaluated in the clinic on Study Days 1, 3 and 7. Subjects who remained symptomatic on Study Day 7 were allowed to continue in the study for a 7-day, double-blind extension period at the discretion of the Investigator. Subjects were contacted by telephone for a safety follow-up 7 days after the last dose of study medication.

A pharmacokinetic (PK) substudy was conducted at selected sites. These sites obtained blood samples for PK analysis at the end of the 7-day treatment period and the 14-day treatment period, if applicable.

    Measured: up to 14 days

Secondary outcomes (2)
  1. Subject Functional Assessment Based on the Roland-Morris Disability Questionnaire (RMDQ)

    Measured: up to 14 days

  2. Adverse Event Assessment

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Carisoprodol SR in people with Lower Back Pain, run by Meda Pharmaceuticals at 68 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 20 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 9 Nov 2011. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 68 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 9 Nov 2011). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Subject Rating of Pain on a 100-point Visual Analog Scale (VAS) (time frame: up to 14 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Nov 2011.
