About this study

Official title: A Phase III Randomized, Placebo-Controlled Clinical Trial to Assess the Safety and Efficacy of Odanacatib (MK-0822) in the Treatment of Men With Osteoporosis Treated With Vitamin D and Calcium

The purpose of this study is to test the hypothesis that treatment with odanacatib will result in increased bone mineral density (BMD) compared to treatment with placebo. This study will also evaluate the safety and efficacy of odanacatib for male osteoporosis participants.

Read the detailed description

The original study was divided into two parts, with the primary analysis of endpoints to occur at 24 months and participants will then remain in the study for an additional 12 months (Part 2). Amendment 1 of the protocol removed the additional 12 month period and the Month 36 BMD analysis was deleted.

    Measured: Baseline and Month 24

  2. Number of Participants Who Experienced an Adverse Event (AE)

    An AE is defined as any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a study drug, whether or not it is considered related to the study drug.

    Measured: Up to 24 months (plus 14 days) after first dose of study drug

  3. Number of Participants Who Discontinued Treatment Due to an AE

    An AE is defined as any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a study drug, whether or not it is considered related to the study drug.

    Measured: Up to 24 months after first dose of study drug

Secondary outcomes (7)
  1. Percentage Change From Baseline in Total Hip BMD at Month 24

    Total hip BMD was assessed by DXA at Baseline and at Month 24.

    Measured: Baseline and Month 24

  2. Percentage Change From Baseline in Femoral Neck BMD at Month 24

    Femoral Neck BMD was assessed by DXA at Baseline and at Month 24.

    Measured: Baseline and Month 24

  3. Percentage Change From Baseline in Trochanter BMD at Month 24

    Trochanter BMD was assessed by DXA at Baseline and at Month 24.

    Measured: Baseline and Month 24

  4. Percentage Change From Baseline in Serum C-Telopeptides of Type 1 Collagen (s-CTx) at Month 24

    Serum samples were collected to evaluate biochemical markers for s-CTx, which were measured at Baseline and at Month 24.

    Measured: Baseline and Month 24

  5. Percentage Change From Baseline in Urine Collagen N-Telopeptide/Creatinine Ratio (U-NTx/Cr) at Month 24

    Urine samples were collected to evaluate biochemical markers for u-NTx/Cr, which were measured at Baseline and at Month 24.

    Measured: Baseline and Month 24

  6. Percentage Change From Baseline in Serum Bone-Specific Alkaline Phosphatase (s-BSAP) at Month 24

    Serum samples were collected to evaluate biochemical markers for s-BSAP, which were measured at Baseline and at Month 24.

    Measured: Baseline and Month 24

  7. Percentage Change From Baseline in Serum N-Terminal Propeptides of Type I Collagen (s-P1NP) at Month 24

    Serum samples were collected to evaluate biochemical markers for s-P1NP, which were measured at Baseline and at Month 24.

    Measured: Baseline and Month 24

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Odanacatib, Vitamin D3 and Calcium carbonate in people with Osteoporosis, run by Merck Sharp & Dohme LLC.

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 13 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 28 Aug 2018. Status can change between updates, so confirm with the study contact before making plans.

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 6 Dec 2017). 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?

Percentage Change From Baseline in Lumbar Spine Bone Mineral Density (BMD) at Month 24 (time frame: Baseline and Month 24). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01120600, which also lists 1 linked publication.

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 28 Aug 2018.
