Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.
- Ages 21 years and older
- All sexes
- No healthy volunteers
- Adult, Older adult
Who may be able to join
- Males and females, 21 years of age or older
- Having mechanical low back pain (LBP) that is predominantly axial, i.e., subjects with low back pain with proximal radiation (above the knee), or subjects with low back pain with distal radiation of pain (below the knee), only if their low back pain component is 50% or more than their leg pain component. This pain will have been present for at least 3 months, with a minimum, average pain score of 4 on a 0-10 numeric rating scale [NRS; a score of 4 is associated with pain of "moderate" intensity, and its use as a cutoff value is supported by the clinical relevance of similar scores found by others.

About this study
Official title: A Pilot Trial of IV Pamidronate for Low Back Pain
The purpose of this study is to determine the test dose of pamidronate for treatment of low back pain in terms of safety, tolerability, and pain relief.
Read the detailed description
Chronic low back pain-an enormous clinical problem which affects large segments of populations throughout the world-causes disability and loss of productivity, and leads to enormous costs in healthcare resources. Efforts to find relatively non-invasive therapies for individuals suffering from this problem are important.
The main objective of this single-center, double-blind study is to determine the optimal dosing regimen-based on safety, tolerability, and pain relief- which should be used in planning a future, large-scale, clinical study to clarify conclusively whether chronic low back pain, unrelated to cancer, can be treated with pamidronate.
Forty-four persons will be recruited for participation. There will be four study groups, each with 7 subjects randomly assigned to pamidronate and 4 to placebo. The dosage for the pamidronate participants will be 30 mg of pamidronate for the first group, 60 mg for the second group, and 90 mg for the third group. Members of the fourth group will receive 2 treatments of 90mg IV pamidronate or placebo.
In this study, scientists also hope to find out if the effectiveness of pamidronate can be predicted with bone scans (a procedure used to see bone inflammation or injuries to the bone), and if improvement in performance of daily tasks is related to the amount of pamidronate a participant receives and to improvement in pain intensity, and to evaluate patient satisfaction with the pamidronate treatments.

There will be four study groups, each with 7 subjects randomly assigned to pamidronate and 4 to placebo. The groups will occur in succession, not parallel. The dosage for group 1 will be 30 mg , 60 mg for group 2, and 90 mg for group 3. Group 4 will receive 2 treatments of 90mg IV pamidronate or placebo.

What is being measured
The primary outcome is the main question the study is designed to answer.
Best dose of pamidronate to be tested in a future large-scale study for treatment of low back pain. Criteria for best dose relate to safety/efficacy of the tested doses in this pilot trial

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing pamidronate in people with Low Back Pain, run by Icahn School of Medicine at Mount Sinai at 1 site 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 4 inclusion and 23 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: status not confirmed, as of the sponsor's last update on 7 Jan 2010. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site 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. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
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?
Best dose of pamidronate to be tested in a future large-scale study for treatment of low back pain. Criteria for best dose relate to safety/efficacy of the tested doses in this pilot trial (time frame: Length of study). 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 7 Jan 2010; AzTrials last refreshed its copy on 26 Oct 2026.
