Key requirements

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 45 to 85 years
Women only
No healthy volunteers
Adult, Older adult

Who may be able to join

Postmenopausal for 5 or more years, defined as no menses for at least 5 years OR at least 5 years status post bilateral oophorectomy
Bone mineral density T-score at the hip or spine of -2.0 or less
Spinal anatomy suitable for dual-energy x-ray absorptiometry (DXA). At the lumbar spine, there is no evidence of vertebral fracture in at least 3 vertebrae in the L1 to L4 region on baseline spine films. (Significant scoliosis, bony trauma, degenerative joint disease, and sequelae of orthopedic procedures that result in anatomy that is unsuitable for accurate bone densitometry must be absent from the lumbar spine.)
At least one hip must be evaluable by DXA (e.g., contain no hardware from orthopedic procedures)
In a state of general health allowing for successful completion of the trial
Agreement to not use any medications to treat osteoporosis during the study

Who cannot join

History of prior osteoporotic fracture (unless declined treatment with or was ineligible for osteoporosis therapy)
Past treatment with osteoporosis medications, steroids, hormone replacement, as well as various other medications that affect bone may be exclusionary. (Different exclusion criteria apply to each bone active drug. For example, any prior use of intravenous (IV) bisphosphonates is not permitted. By contrast, prior use of hormone replacement for several years is permitted if it has not occurred within the past 6 months. Please ask the study doctor for details)
Significant clinical or laboratory abnormalities at the screening visit for the study that, in the opinion of the investigator, could complicate interpretation of the study results or pose additional risk to the patient (for example, patients who are non-ambulatory should be excluded for this reason)

About this study

Official title: A Randomized, Double-Blind, Placebo-Controlled Study to Assess the Safety, Tolerability, and Efficacy of MK-0822 (Cathepsin K Inhibitor) in the Treatment of Postmenopausal Women With Osteoporosis

This is a 1-year base study with a 1-year extension to examine the effects of a new experimental medication (odanacatib [MK-0822]) on postmenopausal osteoporosis. This study will enroll approximately 375 postmenopausal women, and randomly assign them to 4 different doses of odanacatib or to placebo. Measurements performed during the study include: bone mineral density scans, spine x-rays, laboratory blood and urine tests, height measurements and optional bone biopsies (at the end of 2 years).

Study Extension:

Participants who completed 12 months of the base study and 12 months of the first extension were invited to continue in three additional extensions: MK0-822-004-10, which extended the study to 36 months, MK-0822-004-20 (NCT00112437) which extended the study to 60 months, and MK-0822-004-30 (NCT00112437), which extended the study to 120 months.

In the first extension, participants continued to receive the same treatment they received in the 12-month base study.
In the second extension, participants were re-randomized to odanacatib 50 mg OW or placebo OW for 12 months.
In the third extension, participants who were initially randomized to odanacatib 3 mg or placebo OW in the base study received odanacatib 50 mg weekly in Years 4 and 5; all other participants remained on the same treatment they were during Year 3.
In the fourth extension, all participants received odanacatib weekly in Years 6-10.

Study arms for extensions include only odanacatib 50 mg and placebo for the first two extensions and odanacatib 50 mg only for the third extension.

Extension Studies:

MK-0822-004-10 (NCT00112437) Extension: Participant has participated in and completed 24 months of treatment in the base study

Detailed description

Study Extension:

In the first extension, participants continued to receive the same treatment they received in the 12-month base study.
In the second extension, participants were re-randomized to odanacatib 50 mg OW or placebo OW for 12 months.
In the third extension, participants who were initially randomized to odanacatib 3 mg or placebo OW in the base study received odanacatib 50 mg weekly in Years 4 and 5; all other participants remained on the same treatment they were during Year 3.
In the fourth extension, all participants received odanacatib weekly in Years 6-10.

Study arms for extensions include only odanacatib 50 mg and placebo for the first two extensions and odanacatib 50 mg only for the third extension.

Past treatment with osteoporosis medications, steroids, hormone replacement, as well as various other medications that affect bone may be exclusionary. (Different exclusion criteria apply to each bone active drug. For example, any prior use of intravenous (IV) bisphosphonates is not permitted. By contrast, prior use of hormone replacement for several years is permitted if it has not occurred within the past 6 months. Please ask the study doctor for details)
Significant clinical or laboratory abnormalities at the screening visit for the study that, in the opinion of the investigator, could complicate interpretation of the study results or pose additional risk to the patient (for example, patients who are non-ambulatory should be excluded for this reason)

Eligibility is decided by the study team after screening; this overview does not establish that a patient qualifies. Full inclusion and exclusion criteria.

Questions about this trial

What is this clinical trial studying?

A Phase 2 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 6 inclusion and 3 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 24 Jan 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 13 May 2010). 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 12 Months (time frame: Baseline and 12 months). The study lists 7 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 NCT00112437, which also lists 4 linked publications.

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 24 Jan 2018; AzTrials last refreshed its copy on 7 Nov 2026.
