    Pharmacodynamics:

    Mechanism of action


    Teriparatide is a recombinant human parathyroid hormone obtained using a strain 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 bones and kidneys. Teriparatide (recombinant human PTH (1-34)) is an active fragment endogenous human PTH.

    The physiological effect of PTH is to stimulate the formation of bone tissue through direct influence on osteoblasts. PTH indirectly increases intestinal absorption and tubular calcium reabsorption, as well as kidney phosphate excretion. Pharmacodynamic properties Biological act PTH is carried out by binding to specific PTH receptors on the surface cells. Teriparatide binds to the same receptors and has the same effect on bones and kidneys as PTH.

    The daily single administration of teriparatide stimulates the formation of new bone tissue on the trabecular and cortical (periosteal and / or endosteal) bone surfaces with a predominant stimulation of osteoblast activity in relation to osteoclast activity. This is confirmed by an increase in the content of markers of bone tissue formation in the blood serum: bone-specific alkaline phosphatase and carboxyterminal propeptide of procollagen type I (PICP). An increase in the content of bone formation markers is accompanied by a secondary increase in the level of markers of bone resorption in the urine: N-lopeptide (NTX) and deoxypyridinoline (DPD), which reflects the physiological interaction of the formation and resorption of bone tissue in the remodeling of the skeleton. 2 hours after the administration of teriparatide, a short-term increase in the serum calcium concentration is observed,which reaches its maximum values ​​in 4-6 hours and returns to the initial values ​​within 16-24 hours. In addition, transient phosphaturia can be observed and insignificant short-term decrease in phosphorus in the blood serum.

    Clinical efficacy

    Postmenopausal osteoporosis

    The main clinical study of teriparatide included 1637 patients with postmenopausal osteoporosis, whose average age was 69.5 years.

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

    The results of therapy with teriparatide for up to 24 months (mean duration of therapy was 19 months) indicate a statistically significant decrease in the incidence of fractures. The incidence of new vertebral fractures (> 1 fracture, in the radiographs at the beginning and at the 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, of the risk - 65%).

    The incidence of multiple vertebral fractures (> 2 fractures, by radiography at the beginning and at the 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, 77%).

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

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

    After 19 months of treatment (mean duration of therapy), an increase in the BMD of the lumbar spine and proximal femur was observed in comparison with placebo by 9% and 4%, respectively (p <0.001). Follow-up after therapy: after termination of therapy with teriparatide 1262 women with postmenopausal osteoporosis from the main study were included in the follow-up study.The main objective of the study was to collect data on the safety of teriparatide. During this observational period, another therapy for osteoporosis was allowed and an additional assessment of vertebral fractures was performed. On average, within 18 months after discontinuation of therapy with teriparatide in the group of patients who had previously taken teriparatide, the number of patients with at least one new vertebral fracture was 41% lower compared with the placebo group (p = 0.004).

    In an open study, 503 patients with postmenopausal severe osteoporosis and low-energy fractures (fractures with minimal trauma) within the previous three years (83% previously received therapy for osteoporosis) received teriparatide for 24 months. At the end of 24 months, the BMD in the lumbar spine, in the proximal femur and femoral neck increased by an average of 10.5%, 2.6%, and 3.9%, respectively, compared with the beginning of the study. From 18 to 24 months, the BMD in the lumbar spine, in the proximal femur and femoral neck increased by 1.4%, 1.2% and 1.6%, respectively.

    Osteoporosis the men


    In a clinical study of men with osteoporosis due to hypogonadism (defined by a low level of free testosterone in the morning or an increased concentration of follicle-stimulating hormone or luteinizing hormone) or with

    Idiopathic osteoporosis was attended by 437 patients, whose average age was 58.7 years. At the time of the beginning of the study, the BMD of the vertebrae and femoral neck according to the T-test was from -2.2 to -2.1, respectively. At the time of the beginning of the study, 35% of the patients had vertebral fractures in the anamnesis, 59% of the patients had fractures of the other site. Every day, all patients took 1000 mg of calcium and at least 400 ME vitamin A D. A significant increase in bone mineral density in the lumbar spine was observed after 3 months. After 12 months of therapy, the BMD of 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 due to long-term treatment with glucocorticosteroids was demonstrated during an 18-month randomizeda double-blind clinical trial with an active reference drug (alendronate 10 mg / day, 428 patients whose mean age was 57 years).

    At the time of the beginning of the study, 28% of the patients had 1 or more vertebral fractures.

    Every day, all patients took 1000 mg of calcium and 800 ME vitamin A D. The study included 277 postmenopausal women, 67 women in the pre-menopausal period and 83 men. After 18 months of therapy, the BMD of the lumbar spine increased by 7.2% (3.4% in the alendronate group, p <0.001), the BMD of the proximal femur increased by 3.6% (2.2% in the alendronate group, p <0.01), the cervical BMD of the femoral neck increased by 3.7% (by 2.1% in the alendronate group, p <0.05).


    In patients who took teriparatide, at

    the period of the study from 18 months to 24 months of therapy for the IUS 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 nontebral fractures were detected in 7.5% of patients (7.0% in the alendronate group, p = 0.84).

    In women in the pre-menopausal period after 18 months of therapy, the increase in BMD was significantly higher in the teriparatide group compared to alendronate: the MIC of the lumbar spine increased by 4.2% (-1.9% in the alendronate group, p <0.001), the MIC of the proximal The femoral bone increased by 3.8% (0.9% in the alendronate group, p = 0.005).


    The processes of mineralization occur without signs of toxic effects on bone cells, and the 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 developing fractures regardless of age, baseline bone metabolism or MPC (reduction in the relative risk of new fractures is 65%).

    Pharmacokinetics:

    Suction

    Teriparatide is well absorbed when administered subcutaneously.

    Distribution


    Absolute bioavailability of the drug is approximately 95%. The distribution volume is approximately 1.7 l / kg. The maximum concentration of teriparatide is reached 30 minutes after subcutaneous injection of 20 μg of the drug and exceeds 4-5 times the upper border normal level of PTH, followed by a decrease in concentration to undetectable values ​​within 3 hours. Metabolism and excretion The half-life of teriparatide with subcutaneous administration is about 1 hour, which reflects the time required for absorption.

    Peripheral metabolism of PTH occurs predominantly in the liver via nonspecific enzymatic mechanisms from followed by excretion through the kidneys. Like endogenous PTH teriparatide does not accumulate in bones or other tissues. Influences of age (age group from 31 to 85 years) on the pharmacokinetics of teriparatide were not observed.

    In patients with mild or moderate renal insufficiency (creatinine clearance from 30 to 72 ml / min), the pharmacokinetics of the drug does not change. Despite the fact that the systemic exposure of teriparatide in men is lower by 20-30% than in women, the recommended dose of teriparatide does not vary with sex.

    body mass, noise in the heart, increased concentration of alkaline phosphatase. Severe cases of cramps or back pain were noted within a few minutes after the injection.

    Description of individual reactions The following phenomena occurred in clinical studies in the teriparatide group with a frequency> 1% compared with the placebo group: vertigo, nausea, pain in the extremities, dizziness, depression, dyspnea.

    When using teriparatide, it is possible to increase the concentration of uric acid in the blood serum.According to clinical data, 2.8% of patients in the teriparatide group had a higher urinary acid concentration than the upper limit of normal, compared with 0.7% of patients in the placebo group. Nevertheless, an increase in the concentration of uric acid in the blood did not adversely affect the course of gout, arthralgia or urolithiasis.

    In large clinical trials, 2.8% of patients had antibodies with cross-reactivity with teriparatide. As a rule, antibodies appeared after 12 months of therapy and disappeared after discontinuation of therapy. In connection with the appearance of antibodies, there were no signs of hypersensitivity reaction, allergic reactions, influence on calcium concentration or influence on the therapeutic response with respect to bone mineral density.

    Overdose:

    Symptoms:

    Overdose can be manifested by prolonged hypercalcemia and the development of orthostatic collapse. Nausea, vomiting, dizziness, headache are also possible.


    Treatment: There is no special antidote. If you suspect an overdose, it is recommended that you cancel the Forsteo® drug, check the serum calcium content, and perform symptomatic therapy.

    Interaction:

    Clinically significant interactions with hydrochlorothiazide, furosemide, digoxin, atenolol, as well as with sustained-release preparations - diltiazem, nifidipine, felodipine, nisoldipine were not noted.

    Co-administration of teriparatide with raloxifene or hormone replacement therapy does not affect the serum calcium and urine levels of calcium.

    Single administration of teriparatide has no effect on the pharmacodynamics of digoxin. Hypercalcemia is a predisposing factor to the development of intoxication with digitalis preparations, therefore teriparatide should be used with caution in patients taking digitalis preparations.

    Special instructions:

    16 hours after the last injection of Forsteo®, as there may be a short-term increase in serum calcium after the injection of teriparatide. Constant monitoring of the concentration of calcium during treatment is not required.

    When taking Forteo®, rare episodes of short-term orthostatic hypotension may occur, which occur within 4 hours after the drug is administered and pass independently for several minutes to several hours when the patient is placed in thelying on the back and are not a contraindication to further treatment.

    Due to the lack of clinical data for long-term treatment with teriparatide, recommended treatment periods should not exceed 18 months.
