Teriparatide is a recombinant human parathyroid hormone produced using a strain of Escherichia coli (using DNA recombination technology). Endogenous parathyroid hormone (PTH), which is a sequence of 84 amino acid residues, is the main regulator of calcium and phosphorus metabolism in the bones and kidneys. Teriparatide (recombinant human PTH (1-34)) is an active fragment of endogenous human PTH. The physiological effect of PTH is to stimulate bone formation through a direct effect on osteoblasts. PTH indirectly increases intestinal absorption and tubular reabsorption of calcium, as well as renal excretion of phosphate. Pharmacodynamic properties The biological effect of PTH is due to binding to specific PTH receptors on the surface of cells. Teriparatide binds to the same receptors and has the same effects on bones and kidneys as PTH. Single daily administration of teriparatide stimulates the formation of new bone tissue on the trabecular and cortical (periosteal and/or endosteal) surfaces of bones with preferential stimulation of osteoblast activity relative to osteoclast activity. This is confirmed by an increase in the levels of markers of bone tissue formation in the blood serum: bone-specific alkaline phosphatase and carboxy-terminal propeptide of type I procollagen (PICP). The increase in the content of bone tissue formation markers is accompanied by a secondary increase in the level of bone resorption markers in urine: N-telopeptide (NTX) and deoxypyridinoline (DPD), which reflects the physiological interaction of the processes of bone tissue formation and resorption in skeletal remodeling. 2 hours after administration of teriparatide, a short-term increase in serum calcium concentration is observed, which reaches maximum values ​​after 4-6 hours and returns to baseline values ​​within 16-24 hours. In addition, transient phosphaturia and a slight short-term decrease in serum phosphorus levels may occur. Clinical effectiveness. Postmenopausal osteoporosis. The main clinical trial of teriparatide included 1637 patients with postmenopausal osteoporosis, with a mean age of 69.5 years. At the start of the study, 90% of patients had suffered 1 or more vertebral fractures and the mean vertebral bone mineral density (BMD) was equivalent to a T-score of -2.6. All patients took 1000 mg of calcium daily and. at least 400 IU vitamin D. Results of teriparatide therapy for up to 24 months (median duration of therapy was 19 months) indicate a statistically significant reduction in the incidence of fractures. The incidence of new vertebral fractures (>1 fracture, as measured by baseline and end-line radiography) in the teriparatide group and placebo group was 5.0% and 14.3%, respectively (p2 fractures, as determined by baseline and end-line radiography). study) in the teriparatide group and placebo group were 1.1% and 4.9%, respectively (p

Forsteo

The parathyroid hormone analogue, which is a sequence of 84 amino acid residues, is the main regulator of Ca2+ and phosphorus metabolism in bone tissue and kidneys. The active substance of the drug is an active fragment of endogenous human parathyroid hormone. The physiological effect of parathyroid hormone is to stimulate bone formation through a direct effect on osteoblasts. Indirectly increases intestinal absorption and tubular reabsorption of Ca2+, as well as phosphate excretion by the kidneys.

The biological effect of parathyroid hormone is carried out by binding to specific receptors on the surface of cells. The active substance of the drug binds to the same receptors and has the same effect on bone tissue and kidneys as parathyroid hormone. Daily single administration of the drug stimulates the formation of new bone tissue on the trabecular and cortical (periosteal and/or endosteal) surfaces of bones with preferential stimulation of osteoblast activity relative to osteoclast activity. This is confirmed by an increase in the content of markers of bone tissue formation in the blood serum: bone-specific ALP and procollagen-1 carboxy-terminal propeptide. An increase in the content of bone tissue formation markers is accompanied by a secondary increase in the concentration of bone resorption markers in urine: N-telopeptide and deoxypyridinoline, which reflects the physiological interaction of the processes of bone tissue formation and resorption in skeletal remodeling. 2 hours after administration of the drug, a short-term increase in the concentration of serum Ca2+ is observed, which reaches maximum values ​​after 4-6 hours and returns to the initial level within 16-24 hours. In addition, transient phosphaturia and a slight short-term decrease in the concentration of phosphorus in the blood serum may be observed. .

During treatment with the drug, bone mineral density (BMD) of the whole body increases by 5-10% (including the lumbar spine, femoral neck and femur).

Mineralization processes occur without signs of toxic effects on bone tissue cells, and the bone tissue formed under the influence of the drug has a normal structure (without the formation of reticulofibrous bone tissue and bone marrow fibrosis).

The use of the drug reduces the risk of developing fractures regardless of age, the initial level of bone metabolism or BMD (the relative reduction in the risk of new fractures is 65%).

Mechanism of action

Teriparatide is a recombinant human parathyroid hormone produced using a strain of Escherichia coli (using DNA recombination technology).
Endogenous parathyroid hormone (PTH), which is a sequence of 84 amino acid residues, is the main regulator of calcium and phosphorus metabolism in the bones and kidneys. Teriparatide (recombinant human PTH (1-34)) is an active fragment of endogenous human PTH. The physiological effect of PTH is to stimulate bone formation through a direct effect on osteoblasts.

In addition, transient phosphaturia and a slight short-term decrease in serum phosphorus levels may occur.

Clinical effectiveness

Postmenopausal osteoporosis

The main clinical trial of teriparatide included 1637 patients with postmenopausal osteoporosis, with a mean age of 69.5 years.

At the start of the study, 90% of patients had suffered 1 or more vertebral fractures and the mean vertebral bone mineral density (BMD) was equivalent to a T-score of -2.6. All patients took 1000 mg of calcium daily and. at least 400 IU vitamin D.

Results of teriparatide therapy for up to 24 months (mean duration of therapy was 19 months) indicate a statistically significant reduction in the incidence of fractures. The incidence of new vertebral fractures (>1 fracture, as measured by radiography at the beginning and end of the study) in the teriparatide group and in the placebo group was 5.0% and 14.3%, respectively (p < 0.001 compared with the placebo group, a relative decrease risk - 65%).

The incidence of multiple vertebral fractures (>2 fractures, as determined by radiography at the beginning and end of the study) in the teriparatide group and in the placebo group was 1.1% and 4.9%, respectively (p < 0.001 compared with the placebo group, relative risk reduction - 77%).

The incidence of nonvertebral low-energy fractures (minimal trauma fractures) in the teriparatide group and placebo group was 2.6% and 5.5%, respectively (p < 0.025 compared with placebo group, relative risk reduction 53%).

The incidence of major nonvertebral low-energy fractures (femur, radius, humerus, ribs, pelvis) in the teriparatide group and placebo group was 1.5% and 3.9%, respectively (p < 0.025 compared with the placebo group, decreased relative risk - 62%).

After 19 months of treatment (median duration of therapy), there was an increase in BMD at the lumbar spine and proximal femur compared to placebo by 9% and 4%, respectively (p < 0.001). Post-therapy follow-up: After completion of teriparatide therapy, 1262 women with postmenopausal osteoporosis from the main study were included in a follow-up study. The primary objective of the study was to collect data on the safety of teriparatide. During this observation period, other osteoporosis therapy was permitted and additional evaluation of vertebral fractures was performed. At an average of 18 months after discontinuation of teriparatide therapy, the number of patients with at least one new vertebral fracture in the teriparatide-experienced group was 41% lower than in the placebo group (p=0.004).

In an open-label study, 503 patients with postmenopausal severe osteoporosis and fragility fractures (minimal trauma fractures) within the previous three years (83% had previously received treatment for osteoporosis) received teriparatide for 24 months.
After 24 months, BMD at the lumbar spine, proximal femur, and femoral neck increased from baseline by an average of 10.5%, 2.6%, and 3.9%, respectively. From 18 to 24 months, BMD at the lumbar spine, proximal femur, and femoral neck increased by 1.4%, 1.2%, and 1.6%, respectively. Osteoporosis in men

In a clinical study of men with osteoporosis due to hypogonadism (defined by low morning free testosterone or elevated follicle-stimulating hormone or luteinizing hormone concentrations) or

437 patients with idiopathic osteoporosis took part, with an average age of 58.7 years. At the start of the study, the BMD of the vertebrae and femoral neck according to the T-criterion ranged from -2.2 to -2.1, respectively. At the start of the study, 35% of patients had a history of vertebral fractures, and 59% of patients had fractures of other locations. All patients took 1000 mg calcium and at least 400 IU vitamin D daily. Significant increases in lumbar spine bone mineral density were noted after 3 months. After 12 months of therapy, BMD at the lumbar spine and proximal femur increased by 5% and 1%, respectively, compared with placebo.

Osteoporosis with long-term therapy

glucocorticosteroids The effectiveness of teriparatide in osteoporosis caused by long-term treatment with glucocorticosteroids was proven in an 18-month randomized, double-blind clinical trial with an active comparator (alendronate 10 mg/day; 428 patients, mean age 57 years).
At the start of the study, 28% of patients had 1 or more vertebral fractures.

All patients took 1000 mg of calcium and 800 IU of vitamin D daily. The study included 277 postmenopausal women, 67 premenopausal women and 83 men. After 18 months of therapy, BMD of the lumbar spine increased by 7.2% (by 3.4% in the alendronate group, p < 0.001), BMD of the proximal femur increased by 3.6% (by 2.2% in the alendronate group, p<0.01), femoral neck BMD increased by 3.7% (by 2.1% in the alendronate group, p<0.05).

In patients taking teriparatide,

study period from 18 months to 24 months of therapy, BMD of the lumbar spine, proximal femur, and femoral neck increased by an additional 1.7%, 0.9%, and 0.4%, respectively.
In the teriparatide group, after 36 months of therapy, new vertebral fractures were detected in 1.7% of patients (7.7% in the alendronate group, p = 0.01), new non-vertebral fractures were detected in 7.5% of patients (7.0% in the alendronate group, p =0.84).

In premenopausal women after 18 months of therapy, the increase in BMD was significantly higher in the teriparatide group compared with alendronate: lumbar spine BMD increased by 4.2% (-1.9% in the alendronate group, p < 0.001), proximal BMD femur increased by 3.8% (0.9% in the alendronate group, p = 0.005).

Mineralization processes occur without signs of toxic effects on bone tissue cells, and bone tissue formed under the influence of teriparatide has a normal structure (without the formation of reticulofibrous bone tissue and bone marrow fibrosis). Teriparatide reduces the risk of fractures regardless of age, baseline bone turnover, or BMD (relative risk reduction for new fractures is 65%).
