A Study to Test the Effect of MK0217A on Vitamin D Inadequacy in Postmenopausal Women With Osteoporosis (0217A-262)

April 17, 2024 updated by: Organon and Co

A Phase III (Phase V Program), Open-Label, Randomized, Referred-Care-Controlled, Clinical Trial to Evaluate the Efficacy and Safety of MK -0217A/Alendronate Sodium-70 mg/Vitamin D3 5600 I.U. Combination Tablet on Vitamin D Inadequacy in the Treatment of Osteoporosis in Postmenopausal Women

A study designed to see if the study drug will increase blood levels of vitamin D, bone mineral density (BMD), improve biochemical markers of bone turnover, and reduce the number of falls as compared to women receiving standard care for osteoporosis.

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: FOSAVANCE 5600
alendronate sodium (+) cholecalciferol
FOSAVANCE 5600 international units (IU)(Alendronate Sodium 70 mg/Vitamin D 5600 IU) combination tablet once weekly for 6 months (Week 26) during the base period and an additional 6-month extension period (Week 52).

Calcium supplied locally by the investigator (containing 500 mg

calcium supplement) daily for 52 weeks (unless the patient's dietary intake of

calcium exceeds 1000 mg per day).

Other: Referred-Care Model
Usual treatment for osteoporosis chosen and prescribed by patients' own physicians.
Usual treatment for osteoporosis chosen and prescribed by patients' own physicians for 6 months (Week 26) during the base period and an additional 6-month extension period (Week 52).

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percentage of Participants With Serum Levels of 25-hydroxyvitamin D Below 20 ng/mL at Week 26
Time Frame: Week 26

Percentage of participants with serum levels of 25-hydroxyvitamin D below

20 nanograms/milliliter (ng/mL) after 26 weeks of treatment with FOSAVANCE 5600 once weekly versus Referred-Care in postmenopausal women with osteoporosis and at increased risk of falls.

Week 26

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percent Change From Baseline at Week 26 in N-Telopeptides of Type 1 Collagen to Urine Creatinine Ratio
Time Frame: Baseline and Week 26
N-Telopeptides of Type 1 Collagen to Urine Creatinine Ratio (NTx) is a urine biochemical marker of bone resorption and measured in nanomoles (nmol) Bone Collagen Equivalents (BCE)/millimoles (mmol) creatinine. The percent change was calculated as: [100 * ((Week 26/Baseline)-1)]. The greater the percent decrease from baseline, the greater the response to therapy.
Baseline and Week 26
Percent Change From Baseline at Week 26 in Bone-Specific Alkaline Phosphatase
Time Frame: Baseline and Week 26
Bone-Specific Alkaline Phosphatase (BSAP) is a serum biochemical marker of bone formation and measured in micrograms/Liter (mcg/L). The percent change was calculated as: [100 * ((Week 26/Baseline)-1)]. The greater the percent decrease from baseline, the greater the response to therapy.
Baseline and Week 26
Percentage of Participants With Serum Levels of 25-hydroxyvitamin D Below 20 ng/mL at Week 52
Time Frame: Week 52

Percentage of participants with serum levels of 25-hydroxyvitamin D below

20 ng/mL after 52 weeks of treatment (6 month extension study) with FOSAVANCE 5600 once weekly versus Referred-Care in postmenopausal women with osteoporosis and at increased risk of falls.

Week 52
Percent Change From Baseline in Lumbar Spine and Total Hip Bone Mineral Density
Time Frame: Baseline and Week 52
Bone Mineral Density (BMD) as measured by Dual Energy X-Ray Absorptiometry (DEXA) and measured in g/cm^2 was obtained at baseline (visit 1) and Week 52 (visit 13) or at early study discontinuation visit. The percent change was calculated as: [100 * ((Week 52/Baseline)-1)]. The greater the percent change from baseline, the greater the response to therapy.
Baseline and Week 52
Falls Per Participant
Time Frame: Up to Week 52

Number of falls per participant was measured.

The fall event rate during the study period was defined as the number of adjudicated falls during the study period divided by the total patient-years in the study. Each participant was to be in the study for approximately one year.

In order to guide and standardize all procedures during the fall adjudication process, a Standard Operating Procedure for Fall Adjudication was created by the

SPONSOR and served as a guideline to standardize operational procedures for fall adjudication.

Up to Week 52
Percent Change From Baseline at Week 52 in N-Telopeptides of Type 1 Collagen to Urine Creatinine Ratio
Time Frame: Baseline and Week 52
NTx is a urine biochemical marker of bone resorption and measured in nanomoles (nmol) Bone Collagen Equivalents (BCE)/millimoles (mmol) creatinine. The percent change was calculated as: [100 * ((Week 52/Baseline)-1)]. The greater the percent decrease from baseline, the greater the response to therapy.
Baseline and Week 52
Percent Change From Baseline at Week 52 in Bone-Specific Alkaline Phosphatase
Time Frame: Baseline and Week 52
BSAP is a serum biochemical marker of bone formation and measured in micrograms/Liter (mcg/L). The percent change was calculated as: [100 * ((Week 52/Baseline)-1)]. The greater the percent decrease from baseline, the greater the response to therapy.
Baseline and Week 52
