Trial summary

Bisphosphonates are drugs that prevent bone loss by blocking the activity of cells that normally resorb bone. The most common examples of these drugs are Boniva and Fosamax. These drugs are available for oral or intravenous dosing and are prescribed at daily, weekly, biweekly, or monthly intervals. Read more about this study

About this study

Official title: Biomarker Identification in Orthopaedic and Oral Maxillofacial Subjects

Bisphosphonates are drugs that prevent bone loss by blocking the activity of cells that normally resorb bone. The most common examples of these drugs are Boniva and Fosamax. These drugs are available for oral or intravenous dosing and are prescribed at daily, weekly, biweekly, or monthly intervals. Among the many thousands of individuals who currently take these medications, certain individuals experience "atypical" femur fractures preceded by prodromal pain, changes in cortical thickening of bone, or bisphosphonate related osteonecrosis of the jaws (BRONJ). Osteonecrosis of the jaws is defined as exposed bone of the jaws for 8 weeks or more and requires surgical treatment.

This study will attempt to identify genomic and rna biomarkers that may play a role in differential metabolism of bisphosphonates or indicate tendency toward the severe adverse events associated with these drugs.

Collected specimens were subjected to Affymetrix DMET™ Plus Solution analysis. Manuscript is in preparation.

Study groupRoleWhat they receive
CASESAdults with current or past history of bisphosphonate treatment (exposed) with Bisphosphonate related Osteonecrosis of the Jaws (BRONJ), or, Adults with current or past history of bisphosphonate treatment (exposed) with atypical fracture
COUNTER MATCHED CONTROLSAdults with current or past history of bisphosphonate treatment (exposed) without bisphosphonate related osteonecrosis of the jaws (BRONJ, or, Adults with current or past history of bisphosphonate treatment (exposed) with typical fracture or joint replacement or osteoporosis
MATCHED CONTROLSAdults without current bisphosphonate treatment (unexposed) with Typical fracture (healthy fracture patients) Adults without current bisphosphonate treatment (unexposed) without BRONJ (healthy oral surgery subjects or adults with radionecrosis of the jaws)
Healthy Adult VolunteersHealthy volunteers with or without current bisphosphonate treatment without jaw or extremity pathologies or injuries to contribute blood and saliva samples only.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Absorption, Distribution, Metabolism, Excretion (ADME) Profiling of DNA from all sample types vs. normative data for the ADME panel and across study groups

    DNA analysis of saliva, blood, and tissues to detect differential response to drugs. DNA will be isolated from each sample and ADME profiling will be performed. Each participant subgroup will be compared to each other using ANOVA modeling. Each participant subgroup will be compared to normative data for the distribution of gene profiles in the general population for each probe on the ADME gene array.

    Measured: Baseline

Secondary outcomes (1)
  1. Differential expression of miRNA biomarkers across participant groups within the study

    The relative abundance of miRNA across each participant subgroup will be compared using ANOVA modeling. Each participant subgroup will be compared to normative data for the distribution of miRNA expression profiles in the general population for each probe when available.

    Measured: Baseline

Questions about this trial

What is this clinical trial studying?

An observational study of Osteoporosis, With or Without Treatment and Bisphosphonate Treatment, run by University of Pennsylvania 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 4 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 13 Jan 2023. 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.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Absorption, Distribution, Metabolism, Excretion (ADME) Profiling of DNA from all sample types vs. normative data for the ADME panel and across study groups (time frame: Baseline). 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 13 Jan 2023.
