Novartis reported results from a phase IV trial of once-yearly Aclasta for the prevention of spine fractures in men with osteoporosis. This randomized, placebo-controlled, parallel-group study enrolled 1,199 males ages 50 to 85 with primary osteoporosis or osteoporosis associated with low serum testosterone levels. Subjects received Aclasta or placebo as an annual 15-to-30-minute intravenous infusion at baseline and at 12 months. Patients also received daily calcium 1,000-1,500mg and vitamin D 800-1200IU. Data showed a significant reduction in the risk of spine fractures by 67% versus placebo over two years (p=0.002). The results also showed Aclasta reduced the risk of one or more new moderate-to-severe spine fractures by 81% at month 12 (p=0.01) and 63% at month 24 (p=0.03) compared with the placebo group. In addition, Aclasta produced significant and sustained improvements in bone mineral density at the spine and hip bones (lumbar spine, total hip and femoral neck bone [p≥0.05 for all comparisons]) and reduced the risk of height loss (-2.2mm and -4.5mm at month 24 for Aclasta and placebo [p=0.002], respectively). The drug was well tolerated. The most frequent adverse events were similar between treatment groups.

Merck issued results from a phase II trial of odanacatib for the treatment of osteoporosis. This randomized, double-blind, placebo-controlled, multi-center study enrolled 243 women with post-menopausal osteoporosis who had been previously treated with alendronate. Patients were at least 60 years of age with low Bone Mineral Density (BMD) T-scores (=-2.5 and >-3.5) at any hip site. Subjects received odanacatib 50mg or placebo once weekly for 24 months. All subjects received vitamin D3 (5600IU/week) and also calcium supplementation, if needed. Data demonstrated that odanacatib (compared to placebo) significantly increased BMD at all three hip sites (+1.73%, +1.83%, +0.83% for the femoral neck, hip trochanter and total hip, respectively, versus -0.94%, -1.35%, -1.87% with placebo), and the lumbar spine (+2.28% versus -0.30% change with placebo). At the distal forearm, BMD changes from baseline at 24 months were -0.92% and -1.14%, which was not statistically significant. Odanacatib was well tolerated. The most frequent adverse events were urinary tract infection, back pain, arthralgia, fractures, bronchitis, nasal pharyngitis and upper respiratory infection. Based on these data, Merck anticipates submitting regulatory applications for odanacatib in the U.S. and E.U. in the first half of 2013, and in Japan in the second half of 2013.

Amgen released positive results from a phase III trial of denosumab for the treatment of postmenopausal osteoporosis. This randomized, double-blind, active controlled, parallel group study enrolled 504 women with low bone mineral density (BMD) who had previously been treated with alendronate (Fosamax). The subjects received denosumab treatment (60 mg twice yearly) or continuing alendronate therapy (70 mg weekly) for twelve months. The primary endpoint was the effect of denosumab treatment on total hip BMD when compared to continuing alendronate therapy at 12 months. The primary endpoint was reached; the relative magnitude of BMD improvement at the total hip was approximately 80 percent greater in the denosumab versus the alendronate group. The secondary endpoints were reached as well, with significant BMD gains at all sites measured including lumbar spine, femoral neck, distal radius, and hip trochanter compared with the group that continued on alendronate. Adverse events were comparable between the treatment arms. Based on the results Amgen plans to continue with the development of denosumab.

Orthogen released positive results from a clinical trial of Orthokine for the treatment of osteoarthritis (OA). This randomized, prospective, placebo-controlled study, dubbed GOAT (German OsteoArthritis Trial) enrolled 376 subjects with OA of the knee joint. The subjects received Orthokine, hyaluronic acid, or placebo for six total treatment periods. Analysis of the subjects was conducted at six weeks, three months and six months using various measurements including the visual analogue scale (VAS) and the WOMAC questionnaire. At baseline the average VAS score was 70 (intense pain). After six months, 57% of the Orthokine group reported a 50-percent reduction compared to 29% and 28% for the hyaluronic acid and placebo groups, respectively. The Orthokine arm also showed improvements of over 50% on the WOMAC survey compared to 20% in the two other treatment arms. Based on the results, the development of Orthokine will continue.
Zelos issued positive results from a phase II extension trial of Ostabolin-C for the treatment of postmenopausal osteoporosis. This double-blind eight month trial enrolled 198 postmenopausal women who received one of four subcutaneous doses of Ostabolin-C (7.5, 15, 30 or 45 microgram/day) or placebo. The primary endpoint, a significant change in lumbar spine bone mineral density (LS-BMD) at one year, was achieved. A maximum mean LS-BMD increase of 11% was observed in all treatment groups. In the 45 microgram dose group, a clinically relevant LS-BMD increase of 3% or more was observed in 79% of the subjects after 4 months and 97% after 12 months. Significant increases in BMD of the hip were also observed. Based on the results, Zelos plans to move ahead with the development of Ostabolin-C.

Novartis released positive results from a phase III trial of Reclast for the treatment of postmenopausal osteoporosis. This randomized, placebo-controlled trial enrolled 7,700 postmenopausal women who received placebo or Reclast as a once yearly, 15 minute infusion. The primary endpoint was the number of new spine and hip fractures over three years compared to placebo. Secondary endpoints included reducing the incidence of non-spine fractures, evaluation of bone mineral density (BMD), normalization of bone turnover markers, and overall safety. Treatment with Reclast provided a 70% reduction in spine fractures and a 41% reduction in hip fractures over three years. Reclast reduced all non-spine, all clinical and all clinical spine fractures by 25%, 33% and 77%, respectively. In addition, bone mineral density increased significantly in the spine by 6.7% and the hip by 6% in women on Reclast compared to placebo. Reclast for this indication is currently under review by the FDA.

Amgen has issued positive results from a phase II study of AMG 162, their investigational monoclonal antibody for the treatment of low bone mineral density (BMD). Interim results indicated that an injection of the drug administered twice during the first year of the study produce significant increases in total hip BMD compared to placebo, the trial’s primary endpoint. Data also demonstrated that the increases in total hip BMD at all trial doses were comparable or superior to those observed with standard weekly administration of Fosamax, an approved low-BMD therapy, the trial’s secondary endpoint; this effect was statistically significant (p<0.001) at a dose of 60 mg AMG 162 twice yearly. This ongoing, multi-center, dose-ranging study randomized a total of 411 postmenopausal women with low lumbar spine BMD to receive one of three doses AMG 162 every three months (6 mg, 14 mg, or 30 mg), one of four doses every six months (14 mg, 60 mg, 100 mg or 210 mg), standard therapy with Fosamax (70 mg weekly), or placebo. Amgen announced that these results would help support their recently initiated pivotal phase III study.

Merck reported positive results from a phase IV trial investigating Fosamax (alendronate sodium), a non-hormonal therapy for the treatment of osteoporosis. Results showed that female subjects who stopped taking standard hormone replacement therapy (HRT) lost significant bone loss. Furthermore, subjects who took Fosamax did not lose this bone mass. Data demonstrated that discontinuation of HRT resulted in a 3.2% loss in bone mineral density (BMD) at the lumbar spine over 12 months in subjects taking placebo. Subjects taking Fosamax experienced a 2.3% increase in BMD at the lumbar spine for a total difference of 5.5% between treatment groups. The 12-month, multicenter, double blind study enrolled 144 postmenopausal female subjects who had discontinued HRT within three months prior to the start of the trial.
February 10, 2003
The University of Pittsburgh School of Medicine reported positive results from a pilot study investigating Parathyroid Hormone Related Protein (PTHrP), a bone anabolic hormone for the treatment of osteoporosis. Results showed that the overall rate of bone density increase was 4.7 % over a three-month period. The findings compare favorably to results reported with the recently approved parathyroid hormone. The treatment was reported to be well tolerated, with no subjects developing hypercalcemia, hypotension, nausea, flushing or other adverse effects. The double blind, placebo-controlled randomized study enrolled 16 postmenopausal subjects with osteoporosis who had been on hormone replacement therapy for an average of eight years. Subjects received either a self-administered injection of PTHrP or placebo and were followed for three months.
