Uses
1 INDICATIONS AND USAGE FORTEO is indicated: For the treatment of postmenopausal women with osteoporosis at high risk for fracture (defined herein as having a history of osteoporotic fracture or multiple risk factors for fracture) or who have failed or are intolerant to other available osteoporosis therapy. In postmenopausal women with osteoporosis, FORTEO reduces the risk of vertebral and nonvertebral fractures. To increase bone mass in men with primary or hypogonadal osteoporosis at high risk for fracture or who have failed or are intolerant to other available osteoporosis therapy. For the treatment of men and women with osteoporosis associated with sustained systemic glucocorticoid therapy (daily dosage equivalent to 5 mg or greater of prednisone) at high risk for fracture or who have failed or are intolerant to other available osteoporosis therapy. FORTEO is a parathyroid hormone analog, (PTH 1-34), indicated for: Treatment of postmenopausal women with osteoporosis at high risk for fracture or patients who have failed or are intolerant to other available osteoporosis therapy ( 1 ) Increase of bone mass in men with primary or hypogonadal osteoporosis at high risk for fracture or patients who have failed or are intolerant to other available osteoporosis therapy ( 1 ) Treatment of men and women with osteoporosis associated with sustained systemic glucocorticoid therapy at high risk for fracture or patients who have failed or are intolerant to other available osteoporosis therapy ( 1 )
Dosage and administration
Recommended dosage is 20 mcg subcutaneously once a day ( 2.1 ) Consider supplemental calcium and Vitamin D based on individual patient needs ( 2.1 ) Administer as a subcutaneous injection into the thigh or abdominal region ( 2.2 ) Administer initially under circumstances in which the patient can sit or lie down if symptoms of orthostatic hypotension occur ( 2.2 ) Use of FORTEO for more than 2 years during a patient's lifetime should only be considered if a patient remains at or has returned to having a high risk for fracture ( 2.3 ) 2.1 Recommended Dosage The recommended dosage is 20 mcg per dose given subcutaneously once a day. Instruct patients to take supplemental calcium and vitamin D if daily dietary intake is inadequate. 2.2 Administration Instructions Administer FORTEO as a subcutaneous injection into the thigh or abdominal region. FORTEO is not approved for intravenous or intramuscular use. FORTEO should be administered initially under circumstances in which the patient can sit or lie down if symptoms of orthostatic hypotension occur [see Warnings and Precautions ( 5.5 )] . Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration (FORTEO is a clear and colorless liquid). Do not use if solid particles appear or if the solution is cloudy or colored. Patients and/or caregivers who administer FORTEO should receive appropriate training and instruction on the proper use of the FORTEO prefilled delivery device (pen) from a qualified health professional. Discard the delivery device 28 days after first use. 2.3 Recommended Treatment Duration Use of FORTEO for more than 2 years during a patient's lifetime should only be considered if a patient remains at or has returned to having a high risk for fracture [see Warnings and Precautions ( 5.2 )] .

Contraindications
4 CONTRAINDICATIONS FORTEO is contraindicated in patients with a history of severe hypersensitivity to teriparatide or any of the inactive ingredients of FORTEO. Reactions have included anaphylaxis and angioedema [see Warnings and Precautions ( 5.1 ), Adverse Reactions ( 6.2 )] . Patients with severe hypersensitivity to teriparatide or any of the inactive ingredients of FORTEO( 4 )
Warnings and precautions
Hypersensitivity Reactions : Anaphylaxis, angioedema, and urticaria have been reported in patients treated with parathyroid hormone analogs, including FORTEO. If signs or symptoms of a hypersensitivity reaction occur, discontinue treatment with FORTEO, initiate supportive care, and monitor until signs and symptoms resolve. Discontinue FORTEO permanently in patients with a severe hypersensitivity reaction to FORTEO. ( 5.1 ) Osteosarcoma : Avoid use in patients with increased risk of osteosarcoma including patients with open epiphyses, metabolic bone diseases including Paget's disease, bone metastases or history of skeletal malignancies, prior external beam or implant radiation therapy involving the skeleton, and hereditary disorders predisposing to osteosarcoma. ( 5.2 ) Hypercalcemia and Cutaneous Calcification : Avoid in patients known to have an underlying hypercalcemic disorder. Discontinue in patients developing worsening of previously stable cutaneous calcification. ( 5.3 ) Risk of Urolithiasis : Consider the risk/benefit in patients with active or recent urolithiasis because of risk of exacerbation ( 5.4 ) Orthostatic Hypotension : Transient orthostatic hypotension may occur with initial doses of FORTEO ( 5.5 ) 5.1 Hypersensitivity Reactions Hypersensitivity reactions, including anaphylaxis, angioedema, and urticaria, have been reported in patients treated with parathyroid hormone (PTH) analogs, including FORTEO [ see Adverse Reactions ( 6.2 ) ]. If signs or symptoms of a hypersensitivity reaction occur, discontinue treatment with FORTEO, initiate appropriate supportive care, and monitor until signs and symptoms resolve. Discontinue FORTEO permanently in patients with a severe hypersensitivity reaction to FORTEO. FORTEO is contraindicated in patients with a history of severe hypersensitivity to teriparatide or any of the inactive ingredients of FORTEO [ see Contraindications ( 4 ) ]. 5.2 Osteosarcoma An increase in the incidence of osteosarcoma (a malignant bone tumor) was observed in male and female rats treated with teriparatide. Osteosarcoma has been reported in patients treated with FORTEO in the post marketing setting; however, an increased risk of osteosarcoma has not been observed in observational studies in humans. There are limited data assessing the risk of osteosarcoma beyond 2 years of FORTEO use [see Dosage and Administration ( 2.3 ), Adverse Reactions ( 6.2 ), and Nonclinical Toxicology ( 13.1 )] . Avoid FORTEO use in patients with (these patients are at increased baseline risk of osteosarcoma): Open epiphyses (pediatric and young adult patients) (FORTEO is not approved in pediatric patients) [see Use in Specific Populations ( 8.4 )] . Metabolic bone diseases other than osteoporosis, including Paget's disease of the bone. Bone metastases or a history of skeletal malignancies. Prior external beam or implant radiation therapy involving the skeleton. Hereditary disorders predisposing to osteosarcoma. 5.3 Hypercalcemia and Cutaneous Calcification Hypercalcemia FORTEO has not been studied in patients with pre-existing hypercalcemia. FORTEO may cause hypercalcemia and may exacerbate hypercalcemia in patients with pre-existing hypercalcemia [see Adverse Reactions ( 6.1 , 6.2 )] . Avoid FORTEO in patients known to have an underlying hypercalcemic disorder, such as primary hyperparathyroidism. Risk of Cutaneous Calcification Including Calciphylaxis Serious reports of calciphylaxis and worsening of previously stable cutaneous calcification have been reported in the post-marketing setting in patients taking FORTEO. Risk factors for development of calciphylaxis include underlying auto-immune disease, kidney failure, and concomitant warfarin or systemic corticosteroid use. Discontinue FORTEO in patients who develop calciphylaxis or worsening of previously stable cutaneous calcification. 5.4 Risk of Urolithiasis In clinical trials, the frequency of urolithiasis was similar in patients treated with FORTEO and patients treated with placebo. However, FORTEO has not been studied in patients with active urolithiasis. If FORTEO-treated patients have pre-existing hypercalciuria or suspected/known active urolithiasis, consider measuring urinary calcium excretion. Consider the risks and benefits of use in patients with active or recent urolithiasis because of the potential to exacerbate this condition. 5.5 Orthostatic Hypotension FORTEO should be administered initially under circumstances in which the patient can sit or lie down if symptoms of orthostatic hypotension occur. In short-term clinical pharmacology studies of FORTEO in healthy volunteers, transient episodes of symptomatic orthostatic hypotension were observed in 5% of volunteers. Typically, these events began within 4 hours of dosing and resolved (without treatment) within a few minutes to a few hours. When transient orthostatic hypotension occurred, it happened within the first several doses, it was relieved by placing the person in a reclining position, and it did not preclude continued treatment. 5.6 Risk of Digoxin Toxicity Hypercalcemia may predispose patients to digitalis toxicity because FORTEO transiently increases serum calcium. Consider the potential onset of signs and symptoms of digitalis toxicity when FORTEO is used in patients receiving digoxin [see Drug Interactions ( 7.1 ) and Clinical Pharmacology ( 12.3 )].
Side effects
The following clinically significant adverse reactions are described elsewhere in the labeling: Hypersensitivity Reactions [ see Warnings and Precautions ( 5.1 ) ] Osteosarcoma [ see Warnings and Precautions ( 5.2 ) ] Hypercalcemia and Cutaneous Calcification [ see Warnings and Precautions ( 5.3 ) ] Risk of Urolithiasis [ see Warnings and Precautions ( 5.4 ) ] Orthostatic Hypotension [ see Warnings and Precautions ( 5.5 ) ] Risk of Digoxin Toxicity [ see Warnings and Precautions ( 5.6 ) ] Most common adverse reactions (>10%) include: arthralgia, pain, and nausea ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Eli Lilly and Company at 1-800-LillyRx (1-800-545-5979) or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch 6.1 Clinical Trials Experience Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to rates in the clinical studies of another drug and may not reflect the rates observed in practice. Men with Primary or Hypogonadal Osteoporosis and Postmenopausal Women with Osteoporosis The safety of FORTEO in the treatment of osteoporosis in men and postmenopausal women was assessed in two randomized, double-blind, placebo-controlled trials of 1382 patients (21% men, 79% women) aged 28 to 86 years (mean 67 years) [see Clinical Studies ( 14.1 , 14.2 )] . The median durations of the trials were 11 months for men and 19 months for women, with 691 patients exposed to FORTEO and 691 patients to placebo. All patients received 1000 mg of calcium plus at least 400 IU of vitamin D supplementation per day. The incidence of all-cause mortality was 1% in the FORTEO group and 1% in the placebo group. The incidence of serious adverse events was 16% in the FORTEO group and 19% in the placebo group. Early discontinuation due to adverse events occurred in 7% in the FORTEO group and 6% in the placebo group. Table 1 lists adverse events from these two trials that occurred in ≥2% of FORTEO-treated and more frequently than placebo-treated patients. Table 1: Percentage of Patients with Adverse Events Reported by at Least 2% of FORTEO-Treated Patients and in More FORTEO-Treated Patients than Placebo-Treated Patients from the Two Principal Osteoporosis Trials in Women and Men Adverse Events are Shown Without Attribution of Causality FORTEO N=691 Placebo N=691 Event Classification (%) (%) Body as a Whole Pain 21.3 20.5 Headache 7.5 7.4 Asthenia 8.7 6.8 Neck pain 3.0 2.7 Cardiovascular Hypertension 7.1 6.8 Angina pectoris 2.5 1.6 Syncope 2.6 1.4 Digestive System Nausea 8.5 6.7 Constipation 5.4 4.5 Diarrhea 5.1 4.6 Dyspepsia 5.2 4.1 Vomiting 3.0 2.3 Gastrointestinal disorder 2.3 2.0 Tooth disorder 2.0 1.3 Musculoskeletal Arthralgia 10.1 8.4 Leg cramps 2.6 1.3 Nervous System Dizziness 8.0 5.4 Depression 4.1 2.7 Insomnia 4.3 3.6 Vertigo 3.8 2.7 Respiratory System Rhinitis 9.6 8.8 Cough increased 6.4 5.5 Pharyngitis 5.5 4.8 Dyspnea 3.6 2.6 Pneumonia 3.9 3.3 Skin and Appendages Rash 4.9 4.5 Sweating 2.2 1.7 Laboratory Findings Serum Calcium — FORTEO transiently increased serum calcium, with the maximal effect observed at approximately 4 to 6 hours post-dose. Serum calcium measured at least 16 hours post-dose was not different from pretreatment levels. In clinical trials, the frequency of at least 1 episode of transient hypercalcemia in the 4 to 6 hours after FORTEO administration was 11% of women and 6% of men treated with FORTEO compared to 2% of women and 0% of the men treated with placebo. The percentage of patients treated with FORTEO whose transient hypercalcemia was verified on consecutive measurements was 3% of women and 1% of men. Urinary Calcium — FORTEO increased urinary calcium excretion, but the frequency of hypercalciuria in clinical trials was similar for patients treated with FORTEO and placebo [see Clinical Pharmacology ( 12.2 )] . Serum Uric Acid — FORTEO increased serum uric acid concentrations. In clinical trials, 3% of FORTEO-treated patients had serum uric acid concentrations above the upper limit of normal compared with 1% of placebo-treated patients. However, the hyperuricemia did not result in an increase in gout, arthralgia, or urolithiasis. Renal Function — No clinically important adverse renal effects were observed in clinical studies. Assessments included creatinine clearance; measurements of blood urea nitrogen (BUN), creatinine, and electrolytes in serum; urine specific gravity and pH; and examination of urine sediment. Men and Women with Glucocorticoid-Induced Osteoporosis The safety of FORTEO in the treatment of men and women with glucocorticoid-induced osteoporosis was assessed in a randomized, double-blind, active-controlled trial of 428 patients (19% men, 81% women) aged 22 to 89 years (mean 57 years) treated with ≥5mg per day prednisone or equivalent for a minimum of 3 months [see Clinical Studies ( 14.3 )] . The duration of the trial was 18 months with 214 patients exposed to FORTEO and 214 patients exposed to an oral daily bisphosphonate (active control). All patients received 1000 mg of calcium plus 800 IU of vitamin D supplementation per day. There was no increase in mortality in the FORTEO group compared to the active control group. The incidence of serious adverse events was 21% in FORTEO patients and 18% in active control patients, and included pneumonia (3% FORTEO, 1% active control). Early discontinuation because of adverse events occurred in 15% of FORTEO patients and 12% of active control patients, and included dizziness (2% FORTEO, 0% active control). Adverse events reported at a higher incidence in the FORTEO group and with at least a 2% difference in FORTEO-treated patients compared with active control-treated patients were: nausea (14%, 7%), gastritis (7%, 3%), pneumonia (6%, 3%), dyspnea (6%, 3%), insomnia (5%, 1%), anxiety (4%, 1%), and herpes zoster (3%, 1%), respectively.
Drug interactions
Digoxin: Transient hypercalcemia may predispose patients to digitalis toxicity ( 5.6 , 7.1 ) 7.1 Digoxin Sporadic case reports have suggested that hypercalcemia may predispose patients to digitalis toxicity. FORTEO may transiently increase serum calcium. Consider the potential onset of signs and symptoms of digitalis toxicity when FORTEO is used in patients receiving digoxin [see Warnings and Precaution ( 5.6 ) and Clinical Pharmacology ( 12.3 )] .
Use in specific populations
Pregnancy: Consider discontinuing when pregnancy is recognized ( 8.1 ) Lactation: Breastfeeding is not recommended ( 8.2 ) Pediatric Use: Safety and effectiveness not established. Avoid use due to increased baseline risk of osteosarcoma ( 5.2 , 8.4 ) 8.1 Pregnancy Risk Summary There are no available data on FORTEO use in pregnant women to evaluate for drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. Consider discontinuing FORTEO when pregnancy is recognized. In animal reproduction studies, teriparatide increased skeletal deviations and variations in mouse offspring at subcutaneous doses equivalent to more than 60 times the recommended 20 mcg human daily dose (based on body surface area, mcg/m 2 ), and produced mild growth retardation and reduced motor activity in rat offspring at subcutaneous doses equivalent to more than 120 times the human dose (see Data) . The background risk of major birth defects and miscarriage for the indicated population is unknown. The background risk in the US general population of major birth defects is 2% to 4% and of miscarriage is 15% to 20% of clinically recognized pregnancies. Data Animal Data In animal reproduction studies, pregnant mice received teriparatide during organogenesis at subcutaneous doses equivalent to 8 to 267 times the human dose (based on body surface area, mcg/m 2 ). At subcutaneous doses ≥60 times the human dose, the fetuses showed an increased incidence of skeletal deviations or variations (interrupted rib, extra vertebra or rib). When pregnant rats received teriparatide during organogenesis at subcutaneous doses 16 to 540 times the human dose, the fetuses showed no abnormal findings. In a perinatal/postnatal study in pregnant rats dosed subcutaneously from organogenesis through lactation, mild growth retardation was observed in female offspring at doses ≥120 times the human dose. Mild growth retardation in male offspring and reduced motor activity in both male and female offspring were observed at maternal doses of 540 times the human dose. There were no developmental or reproductive effects in mice or rats at doses 8 or 16 times the human dose, respectively. 8.2 Lactation Risk Summary It is not known whether teriparatide is excreted in human milk, affects human milk production, or has effects on the breastfed infant. Avoid FORTEO use in women who are breastfeeding. 8.4 Pediatric Use The safety and effectiveness of FORTEO have not been established in pediatric patients. Pediatric patients are at higher baseline risk of osteosarcoma because of open epiphyses [see Warnings and Precautions ( 5.2 )] . 8.5 Geriatric Use Of the patients who received FORTEO in the osteoporosis trial of 1637 postmenopausal women, 75% were 65 years of age and older and 23% were 75 years of age and older. Of the patients who received FORTEO in the trial of 437 men with primary or hypogonadal osteoporosis, 39% were 65 years of age and over and 13% were 75 years of age and over. Of the 214 patients who received FORTEO in the glucocorticoid induced osteoporosis trial, 28% were 65 years of age and older and 9% were 75 years of age and older. No overall differences in safety or effectiveness of FORTEO have been observed between patients 65 years of age and older and younger adult patients. 8.6 Hepatic Impairment No studies have been performed in patients with hepatic impairment [see Clinical Pharmacology ( 12.3 )] . 8.7 Renal Impairment In 5 patients with severe renal impairment (CrCl<30 mL/minute), the AUC and T 1/2 of teriparatide were increased by 73% and 77%, respectively. Maximum serum concentration of teriparatide was not increased. It is unknown whether FORTEO alters the underlying metabolic bone disease seen in chronic renal impairment [see Clinical Pharmacology ( 12.3 )] .

Geriatric use
8.5 Geriatric Use Of the patients who received FORTEO in the osteoporosis trial of 1637 postmenopausal women, 75% were 65 years of age and older and 23% were 75 years of age and older. Of the patients who received FORTEO in the trial of 437 men with primary or hypogonadal osteoporosis, 39% were 65 years of age and over and 13% were 75 years of age and over. Of the 214 patients who received FORTEO in the glucocorticoid induced osteoporosis trial, 28% were 65 years of age and older and 9% were 75 years of age and older. No overall differences in safety or effectiveness of FORTEO have been observed between patients 65 years of age and older and younger adult patients.
Overdosage
In postmarketing spontaneous reports, there have been cases of medication errors in which the entire contents (up to 800 mcg) (40 times the recommended dose) of the FORTEO prefilled delivery device (pen) have been administered as a single dose. Transient events reported have included nausea, weakness/lethargy and hypotension. No fatalities associated with overdose have been reported. Additional signs, symptoms, and complications of FORTEO overdosage may include a delayed hypercalcemic effect, vomiting, dizziness, and headache. Overdose Management — There is no specific antidote for a FORTEO overdosage. Treatment of suspected overdosage should include discontinuation of FORTEO, monitoring of serum calcium and phosphorus, and implementation of appropriate supportive measures, such as hydration.
Description
(teriparatide injection) is a recombinant human parathyroid hormone analog (PTH 1-34). It has an identical sequence to the 34 N-terminal amino acids (the biologically active region) of the 84-amino acid human parathyroid hormone. The molecular formula of teriparatide is C 181 H 291 N 55 O 51 S 2 and molecular weight is 4117.8 daltons. Its amino acid sequence is shown below: Teriparatide is manufactured using a strain of Escherichia coli modified by recombinant DNA technology. FORTEO is supplied as a sterile, colorless, clear, isotonic solution in a glass cartridge which is pre-assembled into a single-patient-use delivery device (pen) for subcutaneous injection. Each delivery device (pen) is filled with volume to allow delivery of 2.24 mL. Each mL contains 250 mcg of teriparatide (as a free base), 0.41 mg of glacial acetic acid, 0.1 mg of sodium acetate (anhydrous), 45.4 mg of mannitol, 3 mg of Metacresol, and Water for Injection. In addition, hydrochloric acid solution 10% and/or sodium hydroxide solution 10% may have been added to adjust the pH to 4. Each prefilled delivery device (pen) delivers 20 mcg of teriparatide per dose for up to 28 days. Each device contains additional volume to allow troubleshooting of the device 2 times. Teriparatide Amino Acid Sequence
Mechanism of action
12.1 Mechanism of Action Endogenous 84-amino acid parathyroid hormone (PTH) is the primary regulator of calcium and phosphate metabolism in bone and kidney. Physiological actions of PTH include regulation of bone metabolism, renal tubular reabsorption of calcium and phosphate, and intestinal calcium absorption. The biological actions of PTH and teriparatide are mediated through binding to specific high-affinity cell-surface receptors. Teriparatide and the 34 N-terminal amino acids of PTH bind to these receptors with the same affinity and have the same physiological actions on bone and kidney. Teriparatide is not expected to accumulate in bone or other tissues. The skeletal effects of teriparatide depend upon the pattern of systemic exposure. Once-daily administration of teriparatide stimulates new bone formation on trabecular and cortical (periosteal and/or endosteal) bone surfaces by preferential stimulation of osteoblastic activity over osteoclastic activity. In monkey studies, teriparatide improved trabecular microarchitecture and increased bone mass and strength by stimulating new bone formation in both cancellous and cortical bone. In humans, the anabolic effects of teriparatide manifest as an increase in skeletal mass, an increase in markers of bone formation and resorption, and an increase in bone strength. By contrast, continuous excess of endogenous PTH, as occurs in hyperparathyroidism, may be detrimental to the skeleton because bone resorption may be stimulated more than bone formation.

Patient information
Advise patients to read the FDA-approved patient labeling (Medication Guide and the User Manual) before starting FORTEO and each time the prescription is renewed. Failure to follow the instructions may result in inaccurate dosing. Hypersensitivity Reactions Advise patients that serious hypersensitivity reactions, including anaphylaxis, angioedema, and urticaria, can occur with FORTEO. Advise patients to discontinue FORTEO and promptly seek medical attention if signs or symptoms of hypersensitivity reactions occur [ see Contraindications ( 4 ), Warnings and Precautions ( 5.1 ) ]. Osteosarcoma Patients should be made aware that in rats, teriparatide caused an increase in the incidence of osteosarcoma (a malignant bone tumor). Although cases of osteosarcoma have been reported in patients using FORTEO no increased risk of osteosarcoma was observed in adult humans treated with FORTEO [see Warnings and Precautions ( 5.2 )] . Hypercalcemia Instruct patients taking FORTEO to contact a health care provider if they develop persistent symptoms of hypercalcemia (e.g., nausea, vomiting, constipation, lethargy, muscle weakness) [see Warnings and Precautions ( 5.3 )] . Orthostatic Hypotension When initiating FORTEO treatment, instruct patients to be prepared to immediately sit or lie down during or after administration in case they feel lightheaded or have palpitations after the injection. Instruct patients to sit or lie down until the symptoms resolve. If symptoms persist or worsen, instruct patients to consult a healthcare provider before continuing treatment [see Warnings and Precautions ( 5.5 )] . Other Osteoporosis Treatment Modalities Patients should be informed regarding the roles of supplemental calcium and/or vitamin D. Use of the Prefilled Delivery Device (Pen) Instruct patients and caregivers who administer FORTEO on how to properly use the delivery device (refer to User Manual) , to properly dispose of needles, and not to share their prefilled delivery device with other patients. Instruct patients and caregivers who administer FORTEO that the contents of the delivery device should not be transferred to a syringe.
