Methods: 125 postmenopausal women (mean age 71.7 ± 8.5 years, 91.5%<br />

prevalent fractures, 95.7% prior antiresorptive treatment) were prospectively<br />

randomized after 9 months of TPTD treatment into three open-label groups<br />

for another 9 months: ALN (70 mg/week, 41 patients) or RAL (60 mg/day, 37<br />

patients) added to TPTD treatment or no additional medication (TPTD monotherapy,<br />

47 patients). After TPTD termination, patients were treated with the<br />

respective antiresorptive agent for another 12 months (extension phase). All<br />

subjects received 1000mg calcium and 800 IU vitamin D daily. Serum levels of<br />

intact amino terminal propeptide of type I procollagen (PINP) and type 1 collagen<br />

cross-linked C-telopeptide (CTX) as well as BMD measured by DXA at<br />

lumbar spine, total hip and femoral neck were evaluated at randomization, end<br />

of TPTD treatment, and at 6 and 12 months in the extension phase.<br />

Results: Lumbar spine BMD increased in all groups during the extension<br />

phase. Compared with values at the time of randomization, at the end of the<br />

extension phase, the increase in lumbar spine BMD was significantly higher in<br />

the ALN (10.1 ± 7.3%, p=0.002) and RAL (8.4 ± 5.4%, p=0.019) groups than in<br />

the TPTD monotherapy group (4.5 ± 10.3%). At total hip addition of RAL (0.5<br />

± 3.8%) did not alter the effects of TPTD monotherapy on BMD (0.5 ± 5.5%).<br />

Addition of ALN resulted in a superior increase in both total hip BMD (8.2 ±<br />

5.8%) and femoral neck BMD (9.1 ± 10.1%, p
