Outcomes

Primary Outcome Measures

Change From Baseline to 3 Months in Mineralizing Surface (MS) /Bone Surface (BS) in the Cancellous Compartment (CC) of the Iliac Crest Bone Biopsies
MS /BS is a measure of the proportion of BS on which new mineralized bone is deposited at the time of DEM or TET labeling, and calculated as the sum of the total extent of double label (DL) plus half the extent of single label (SL) divided by BS. At baseline (18 days prior to randomization / study drug administration), DEM was administered (3 days on, 12 days off, 3 days on). 22 days prior to the biopsy procedure (biopsy obtained 3 months post first dose of study drug), TET was administered (same dosing schedule as DEM). Both DEM and TET temporarily bind to new bone and fluoresce under UV light. New bone in the biopsy was seen as the amount of bone between the 2 fluorescently DEM- or TET-labeled lines under a microscope. A DL indicated active bone formation and a SL or no label (NL) suggested varying degrees of suppression of bone formation.

Percentage of Overfilled Remodeling Sites in the CC, EC and PC of the Iliac Crest Bone Biopsies
The percentage of overfilled remodeling sites in the CC, EC, and PC were defined as the percentage of observed remodeling units in which the second DL (TET) extended beyond the limits of the scalloped reversal line and into the adjacent, previously unresorbed surface of the bone. Percentage = (overfilled remodeling bone formation unit / total bone formation unit) * 100.
Change From Baseline to 3 Months in Label Length Within Each Basic Multicellular Unit (BMU) in the CC, EC, IC and PC of the Iliac Crest Bone Biopsies
BMUs are local groups of osteoblasts and osteoclasts that act in concert to complete a single remodeling cycle.

At baseline (18 days prior to randomization / study drug administration), DEM was administered. 22 days prior to the biopsy procedure (biopsy obtained 3 months post first dose of study drug), TET was administered. New bone in the biopsy was seen as the amount of bone between the 2 fluorescently DEM- or TET-labeled lines under a microscope.

At baseline (18 days prior to randomization / study drug administration), DEM was administered. 22 days prior to the biopsy procedure (biopsy obtained 3 months post first dose of study drug), TET was administered. New bone in the biopsy was seen as the amount of bone between the 2 fluorescently DEM- or TET-labeled lines under a microscope. A DL indicates active bone formation, a SL or NL suggests suppression of bone formation. BFR = MAR * (MS/BS). SL cases were imputed to a value of 0.3 mcm/day or counted as missing.

Percentage Change From Baseline to 1, 3, and 6 Months in Serum Carboxyterminal Cross-Linking Telopeptide of Type I Collagen (CTX)
CTX is a marker of bone turnover and is a measure of bone resorption. Percentage = (CTX value at specified time points - CTX value at baseline) / (CTX value at baseline) * 100.
Activation Frequency (Ac.f) in the CC, EC and IC of the Iliac Crest
Ac.f is the probability of new remodeling cycles initiated on the BS per year. Ac.f = (BFR/BS) / wall thickness. At baseline (18 days prior to randomization / study drug administration), DEM was administered. 22 days prior to the biopsy procedure (biopsy obtained 3 months post first dose of study drug), TET was administered. New bone in the biopsy was seen as the amount of bone between the 2 fluorescently DEM- or TET-labeled lines under a microscope.

CTX is a marker of bone turnover and is a measure of bone resorption. Percentage = (CTX value at specified time points - CTX value at baseline) / (CTX value at baseline) * 100.
Time Frame
Baseline, 1, 3, and 6 months post first dose of study drug
Title
Activation Frequency (Ac.f) in the CC, EC and IC of the Iliac Crest
Description
Ac.f is the probability of new remodeling cycles initiated on the BS per year. Ac.f = (BFR/BS) / wall thickness. At baseline (18 days prior to randomization / study drug administration), DEM was administered. 22 days prior to the biopsy procedure (biopsy obtained 3 months post first dose of study drug), TET was administered. New bone in the biopsy was seen as the amount of bone between the 2 fluorescently DEM- or TET-labeled lines under a microscope. A DL indicated active bone formation and a SL or NL suggests suppression of bone formation. SL cases were imputed to a value of 0.3 µm/day or counted as missing. NL cases were assigned a value of zero.
Time Frame
3 months post first dose of study drug
Title
Adjusted Apposition Rate (Aj.AR) in the CC, EC and IC of the Iliac Crest
Description
Aj.AR is MAR averaged over the entire osteoid surface and in a steady state is an estimate of the mean rate of matrix apposition. At baseline (18 days prior to randomization / study drug administration), DEM was administered. 22 days prior to the biopsy procedure (biopsy obtained 3 months post first dose of study drug), TET was administered. New bone in the biopsy was seen as the amount of bone between the 2 fluorescently DEM- or TET-labeled lines under a microscope. A DL indicated active bone formation and a SL or NL suggested suppression of bone formation. BFR = MAR * (MS/BS). SL cases were imputed to a value of 0.3 µm/day or counted as missing. NL cases were counted as missing.
Time Frame
3 months post first dose of study drug
Title
Percentage of Osteoid Volume (OV)/Bone Volume (BV) in the CC of the Iliac Crest
Description
OV is the percentage of a given volume of bone tissue that consists of new unmineralized bone matrix (osteoid). Percentage = (OV/BV) *100.
Time Frame
3 months post first dose of study drug
Title
Percentage of Osteoid Surface (OS)/Bone Surface (BS) in the CC, EC and IC of the Iliac Crest
Description
OS is the percentage of the entire trabecular BS that is covered by osteoid. Percentage = (OS / BS) *100.
Time Frame
3 months post first dose of study drug
Title
Osteoid Thickness (O.Th) in the CC, EC and IC of the Iliac Crest
Description
O.Th is a measure of the average thickness of osteoid seams.
Time Frame
3 months post first dose of study drug
Title
Wall Thickness (W.Th) in the CC, EC and IC of the Iliac Crest
Description
W.Th is the distance from the cement line to the marrow space of completed trabecular bone packets.
Time Frame
3 months post first dose of study drug
Title
Percentage of Eroded Surface/Bone Surface (ES/BS) in the CC, EC and IC of the Iliac Crest
Description
ES/BS is the fraction of the entire trabecular surface occupied by resorption bays, including both those with and without osteoclasts. It is an indicator of bone resorption. Percentage = (ES/BS) *100.
Time Frame
3 months post first dose of study drug
Other Pre-specified Outcome Measures:
Title
Average Length of DLs in the CC, EC, IC and PC of the Iliac Crest
Description
The length of TET DLs is a measure of the extent of bone formation in each compartment within individual remodeling units and is measured in mm. At baseline (18 days prior to randomization / study drug administration), DEM was administered. 22 days prior to the biopsy procedure (biopsy obtained 3 months post first dose of study drug), TET was administered. New bone in the biopsy was seen as the amount of bone between the 2 fluorescently DEM- or TET-labeled lines under a microscope. A DL indicated active bone formation.
Time Frame
3 months post first dose of study drug
