Study Endpoints

Primary Endpoints

Percentage Change From Baseline in Lumbar Spine Bone Mineral Density (BMD) at Month 24

Lumbar spine BMD was assessed by dual energy X-ray absorptiometry (DXA) at Baseline and at Month 24.

Number of Participants Who Experienced an Adverse Event (AE)
Up to 24 months (plus 14 days) after first dose of study drug

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.

Number of Participants Who Discontinued Treatment Due to an AE
Up to 24 months after first dose of study drug

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.

Percent Change From Baseline to Month 12 in Lumbar Spine Areal Bone Mineral Density (aBMD)
Baseline, 12 months

aBMD (g/cm\^2) was measured by dual-energy X-ray absorptiometry (DXA) at the lumbar spine and mean BMD measurements from at least 3 evaluable lumbar spine vertebrae (L1-L4) were used. If a vertebra was fractured at baseline or became fractured during the study, its BMD measurement was excluded from the analysis and the lumbar spine BMD was recalculated based on the three remaining vertebrae. aBMD data was centrally evaluated and all areal BMD measurements included a longitudinal BMD correction factor as determined by the quality control center. aBMD at the lumbar spine was assessed at the Screening visit (Baseline), Month 6, Month 12, and Month 24 for the repeated measures longitudinal Analysis of Covariates (ANCOVA) model, with percent change from baseline at Months 12 and 24 pre-specified to be reported as primary and secondary outcome measures, respectively.

Percentage of Participants Discontinuing Study Drug Due to an AE
Up to 24 months

An AE was defined as any unfavorable and unintended sign including an abnormal laboratory finding, symptom or disease associated with the use of a medical treatment or procedure, regardless of whether it was considered related to the medical treatment or procedure, that occurred during the course of the study.

Percent Change From Baseline to Week 52 in Lumbar Spine Bone Mineral Density (BMD) at Lumbar Vertebrae 1 to 4 (L1-L4)
Baseline (Observation visit to Wk 0 treatment visit), Week 52

BMD (g/cm2) data was measured by dual-energy X-ray absorptiometry (DXA) at lumbar spine vertebrae 1 through 4 (L1-L4) from anterior view at the Observation visit (up to 5 weeks before Treatment Period), Week 0 (start of Treatment Period) and Week 52 (end of Treatment Period) or at discontinuation. Baseline was defined as the average of the 2 values collected at the Observation visit and Week 0 visit. Percent change from baseline in BMD = (\[BMD at Week 52 visit\] - \[baseline BMD\] ÷ baseline BMD) × 100. Measurements were performed using the Hologic Quantitative Digital Radiography (QDR) Series densitometer, and by same machine and under same scan mode throughout the study period. BMD data was centrally judged.

Number of Participants That Experienced an Adverse Event (AE)
From first dose up to Post-Study (up to 54 weeks)

An AE was defined as any unfavorable and unintended change in the structure (sign), function (symptoms), or chemistry of the body (laboratory data) temporally associated with the use of the SPONSOR's products (including placebo), whether or not considered related to the use of the product. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition which is temporally associated with the use of the SPONSOR's product was also an AE. The number of participants that experienced at least one AE was reported for each treatment arm.

Number of Participants That Discontinued Study Drug Due to an AE
From first dose up to end of treatment (up to 52 weeks)

An AE was defined as any unfavorable and unintended change in the structure (sign), function (symptoms), or chemistry of the body (laboratory data) temporally associated with the use of the SPONSOR's products (including placebo), whether or not considered related to the use of the product. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition which is temporally associated with the use of the SPONSOR's product was also an AE. The number of participants that discontinued study drug due to an AE was reported for each treatment arm. Participants may have discontinued study drug but continued on the trial.

Weighted Average Inhibition (WAI) of Urine Aminoterminal Crosslinked Telopeptide of Type I Collagen (u-NTx/Cr) After Administration of Odanacatib 50 mg or Placebo Qw for 4 Weeks in Healthy Males and Postmenopausal Females
Baseline to Week 4

uNTx/Cr is a biomarker of bone resorption. Urine samples were obtained predose on Day 1 (Baseline) and at various timepoints up to 336 hr postdose on Day 22 (Week 4). Fold change from baseline in time weighted average (TWA) of uNTx/Cr on log scale was analyzed via a linear mixed effect model. All analyses were carried out on the log-fold scale and final results were reported on the original percent scale in WAI after back transformation. The conversion used was weighted average inhibition (WAI) = (1-exp \[mean\])\*100, where the mean was the least squares (LS) mean of log-transformed ratio (TWA/baseline) from the above model.

Frequently asked questions about odanacatib

What is Odanacatib used for?

Odanacatib is an investigational small molecule being developed for the treatment of osteoporosis, including postmenopausal osteoporosis. It is a cathepsin K inhibitor that is being studied for its potential to reduce bone resorption and improve bone mineral density in patients with this condition.

Who makes Odanacatib?

Odanacatib is being developed by Merck & Company, Inc., a pharmaceutical company traded on the New York Stock Exchange under the ticker symbol MRK. The drug is currently in Phase 2 clinical development for the treatment of osteoporosis.

What phase is Odanacatib in?

Odanacatib is in Phase 2 clinical development. It is an investigational drug and has not been approved by the FDA. The drug is being studied for the treatment of osteoporosis, including postmenopausal osteoporosis, in clinical trials.

What clinical trials is Odanacatib in?

Odanacatib has been studied in several clinical trials, including NCT00620113, a Phase 2 study in postmenopausal osteoporosis with 287 participants, and multiple Phase 1 trials such as NCT00769418, NCT00863525, and NCT00863590, which evaluated safety, tolerability, and pharmacokinetics in healthy volunteers.

How does Odanacatib work?

Odanacatib works by inhibiting cathepsin K, an enzyme involved in bone resorption. By blocking this enzyme, the drug aims to reduce bone breakdown and help maintain bone density in patients with osteoporosis.

Is Odanacatib the same as MK-0822?

Yes, Odanacatib is also known as MK-0822. Clinical trials for the drug, such as NCT00620113, refer to it by this alternative name. Both names refer to the same investigational compound being developed by Merck.
