Evaluation of the Effects of Teriparatide on Skeleton Images in Postmenopausal Women With Osteoporosis
2010年7月14日 更新者：Eli Lilly and Company
The Use of Nuclear Scintigraphy to Evaluate the Anabolic Effects of Teriparatide on the Skeleton in Postmenopausal Women With Osteoporosis
The purpose of this study is to evaluate the effects of teriparatide on skeleton images in postmenopausal women with osteoporosis.
Teriparatide is a bone formation agent that stimulates the production of new bone in the skeleton.
This process of bone formation can be studied using a technique commonly referred to as a bone scan or nuclear scintigraphy.
This trial will test whether bone scans will identify areas of the skeleton that are forming new bone during teriparatide therapy.
It also will study what these areas look like after therapy is stopped.

Change From Baseline in Whole Skeleton Skeletal Plasma Clearance of 99m Technetium Methylene Diphosphonate (99m Tc-MDP) to 18 Months
大体时间：baseline, 18 months
|
Skeletal plasma clearance is defined as the volume of plasma cleared of tracer (99m Tc-MDP) by the skeleton per unit time (milliliter/minute).
Kbone is the rate constant representing plasma clearance of tracer to bone.
The Patlak plot method was used to evaluate whole skeleton 99mTc-MDP skeletal plasma clearance (Kbone).

Change in Skeletal Plasma Clearance of 99m Technetium Methylene Diphosphonate (99m Tc-MDP) in the Whole Skeleton, Skull, Mandible, Spine, Pelvis, Upper Extremities, and Lower Extremities

Skeletal plasma clearance is defined as the volume of plasma cleared of tracer (99m Tc-MDP) by the skeleton per unit time (milliliter/minute).
Kbone is the rate constant representing plasma clearance of tracer to bone.
The Patlak plot method was used to evaluate whole skeleton 99mTc-MDP skeletal plasma clearance (Kbone) and to derive regional values for the skull, mandible, spine, pelvis, and upper and lower extremities.

Change in Skeletal Uptake of 99m Technetium Methylene Diphosphonate (99m Tc-MDP) in the Whole Skeleton, Skull, Mandible, Spine, Pelvis, Upper Extremities, and Lower Extremities
大体时间：Baseline, 3 months, 18 months, 24 months
|
Skeletal uptake describes the percent uptake of radionuclide tracer by the skeleton when compared to baseline or other post-baseline measures.
Skeletal uptake is defined as percentage of uptake of 99mTc-MDP 4 hours after injection.
This value differs from skeletal plasma clearance measurements because it only quantifies the amount of 99mTc-MDP taken up by bone without consideration of concentration of tracer in the plasma.

Change in Qualitative Visual Scores of Focal Uptake of 99m Technetium Methylene Diphosphonate (99m Tc-MDP) in the Whole Skeleton
大体时间：Baseline, 3 months, 18 months, 24 months
|
Changes in focal uptake (localized, defined areas of uptake) were visually scored and compared to baseline or other post-baseline assessments.
Changes were rated on a scale from 0-4: 0=no clinically significant focal areas of skeletal uptake; 1=focal areas affecting <1% of skeleton; 2=focal areas affecting >=5% of skeleton; 3=focal areas affecting >=20% of skeleton; 4=focal areas affecting >=50% of skeleton.

Number of Participants With Changes in Diffuse Uptake of 99m Tc-MDP - Qualitative Visual Assessment in the Whole Skeleton
大体时间：baseline, 3 months, 18 months, 24 months
|
Changes in diffuse uptake were determined by comparing diffuse uptake to baseline or other post-baseline observations.
Diffuse uptake indicates response to therapy (during active treatment, increased diffuse uptake was expected; after the 6-month withdrawal period, decreased diffuse uptake was expected).
Qualitative visual scoring of changes in the bone scan images were performed jointly by 3 reviewers who classified changes in the whole skeleton into 4 groups as follows: possible decreased response, no response, possible response, and definite response.
