I. INTRODUCTION
Based on the review of the data and the Applicant’s response to the questions raised by RMS and CMSs on quality, safety, and efficacy, the RMS considers that the application for Teriparatide 20 Mikrogramm / 80 Mikroliter Injektionslösung im Fertigpen (under different trade names), indicated in adults for the treatment of osteoporosis in postmenopausal women and in men at increased risk of fracture, in postmenopausal women, a significant reduction in the incidence of vertebral and nonvertebral fractures but not hip fractures has been demonstrated, and for the treatment of osteoporosis associated with sustained systemic glucocorticoid therapy in women and men at increased risk for fracture
is approved.
II. EXECUTIVE SUMMARY
-
II.1 Problem statement
The application has been filed in accordance with Article 10(1) of Directive 2001/83/EC (generic medicinal product). However, for the reference medicinal product Forsteo teriparatide is produced based on recombinant DNA technology, while for the current application teriparatide is manufactured by chemical solid phase peptide synthesis.
-
II.2 About the product
Endogenous parathyroid hormone (PTH) is the primary regulator of calcium and phosphate metabolism in bone and kidney; teriparatide is the active fragment (1–34) of human PTH. Physiological actions include stimulation of bone formation by direct effects on bone forming cells (osteoblasts) indirectly increasing the intestinal absorption of calcium and increasing the tubular reabsorption of calcium and excretion of phosphate by the kidney.
Teriparatide is a bone formation agent to treat osteoporosis. The skeletal effects of teriparatide depend upon the pattern of systemic exposure. Once-daily administration of teriparatide increases apposition of new bone on trabecular and cortical bone surfaces by preferential stimulation of osteoblastic activity over osteoclastic activity.
The claimed in indication is in line with the originator’s being treatment of osteoporosis in postmenopausal women and in men at increased risk of fracture and treatment of osteoporosis associated with sustained systemic glucocorticoid therapy in women and men at increased risk for fracture; treatment is indicated in adults only. Twenty (20) μg are given in 80 μl, solution by subcutaneous injection (SC) with a pre-filled pen once daily.
The pharmacotherapeutic group is calcium homeostasis, parathyroid hormones and analogues, ATC Code H05 AA02.

II.3 General comments on the submitted dossier
The application for a teriparatide containing medicinal product has been filed in accordance with Article 10(1) of Directive 2001/83/EC (generic medicinal product), although in the current application teriparatide is manufactured by chemical solid phase peptide synthesis, while for the reference medicinal product Forsteo, teriparatide is produced based on recombinant DNA technology.
The clinical overview is in general adequate in its discussion of the efficacy, safety, pharmacokinetics, and pharmacodynamics of teriparatide, and with regards to the review of available literature. The SmPC and PL for the proposed product are essentially in line with the reference product.
The active substance teriparatide is not considered a new active substance. Teriparatide was first approved in the USA in November 2002 (Forteo) for the treatment of osteoporosis in adult women and men and in the EU in June 2003 (Forsteo; EU/1/03/247/001, EU/1/03/247/002) for the treatment of established osteoporosis in postmenopausal women; the latter indication was extended to treatment of osteoporosis in postmenopausal women and in men at increased risk of fracture in 2007 and furthermore to include treatment of glucocorticoid-induced osteoporosis in 2008.

Drug Product
TERIPARATIDE 20μg/80μL solution for injection is a clear, colourless solution, free from visible particles, packaged in a glass cartridge (2.4 mL extractable volume in 3 mL cartridge) closed with a plunger at one end and with a rubber disc and aluminium cap (combi seal) at the other end. The filled cartridge is assembled into a pen injector intended for multiple injections.
Pharmaceutical Development
The Applicant’s intention was to develop their own product as similar as possible to the originator’ s product Forsteo. Thus, no drug product formulation studies were performed. The only and most important difference between reference product and generic product is the manufacturing process of the active substance. While the originator Forsteo contains recombinantly produced teriparatide, the active substance in TERIPARATIDE 20μg/80μL is of synthetic origin. An analytical comparability study was performed to investigate the differences between test and reference product. Six batches of the reference product Forsteo and four batches of Teriparatide 20μg/80μL solution for injection were included in the analytical comparability study. Potential structural differences due to the different synthetic pathways are deemed satisfactorily excluded by the comprehensive characterisation data provided.
Overall, the Applicant’s conclusion on Teriparatide 20µg/80µL being similar to Forsteo is supported. The comprehensive data provided in the response document are deemed satisfactorily supporting the similarity claim. Data on effectiveness of antimicrobial preservation generated with three batches of teriparatide 20µg/80µLhave been provided.
Manufacture
Manufacturing of Teriparatide 20μg/80μL consists of compounding including the dissolution of teriparatide active substance in buffer, pH adjustment, sterile filtration using 0.22µm filters, and aseptic filling, stoppering and crimping. Then, the pen assembly is performed. All steps of the manufacturing process are satisfactorily described in the dossier, together with control of critical steps.

-
III.2 Non-clinical aspects
Pharmacodynamic, pharmacokinetic and toxicological properties of teriparatide are well known. As teriparatide is a widely used, well-known active substance, the Applicant has not provided additional studies and further studies are not required. Overview based on literature review is, thus, appropriate. The non-clinical overview has been written and dated August 2018. Report refers 39 publications up to year 2018.
The non-clinical overview on the pre-clinical pharmacology, pharmacokinetics and toxicology is adequate.
Environmental Risk Assessment (ERA)
The active substance is a peptide, the use of which will not alter the concentration or distribution of the substance in the environment. Therefore, teriparatide is not expected to pose a risk to the environment.
-
III.3 Clinical aspects
The clinical overview has been written and signed 6 September 2018. The clinical overview provides an adequate description of the clinical pharmacokinetics, pharmacodynamics, efficacy, and safety of teriparatide. The clinical overview is acceptable.
The proposed indications for TERIPARATIDE 20 µg / 80µl Injektionslösung in einem vorgefüllten Injektor et al. are:
TERIPARATIDE 20 µg / 80µl Injektionslösung is indicated in adults.
Treatment of osteoporosis in postmenopausal women and in men at increased risk of fracture. In postmenopausal women, a significant reduction in the incidence of vertebral and non- vertebral fractures but not hip fractures has been demonstrated.
Treatment of osteoporosis associated with sustained systemic glucocorticoid therapy in women and men at increased risk for fracture.
The proposed Posology is:
The recommended dose of TERIPARATIDE 20 µg / 80µl Injektionslösung is 20 µg administered once daily.
The maximum total duration of treatment with TERIPARATIDE 20 µg / 80µl Injektionslösung should be 24 months (see section 4.4). The 24-month course of TERIPARATIDE 20 µg / 80µl Injektionslösung should not be repeated over a patient’s lifetime.
Patients should receive supplemental calcium and vitamin D supplements if dietary intake is inadequate.
Following cessation of TERIPARATIDE 20 µg / 80µl Injektionslösung therapy, patients may be continued on other osteoporosis therapies.
The proposed indications and posology are consistent with the indications for the reference product Forsteo.
Pharmacokinetics
Distribution
The volume of distribution is approximately 1.7 L/kg. The half-life of teriparatide is approximately 1 hour when administered subcutaneously, which reflects the time required for absorption from the injection site.
Biotransformation
No metabolism or excretion studies have been performed with teriparatide. But the peripheral metabolism of parathyroid hormone is believed to occur predominantly in liver and kidney.
Elimination
Teriparatide is eliminated through hepatic and extra-hepatic clearance (approximately 62 L/hr in women and 94 L/hr in men).
Elderly
No differences in teriparatide pharmacokinetics were detected with regard to age (range 31 to 85 years). Dosage adjustment based on age is not required.
Pharmacodynamics
Endogenous PTH, an 84-amino acid peptide, plays a central role in calcium and phosphate metabolism in bone and kidneys. Its physiological effects include stimulation of bone formation by directly affecting osteoblasts and by increasing renal tubular reabsorption of calcium and excretion of phosphate as well as indirectly increasing intestinal absorption of calcium via its effects on 1,25-dihydroxycholecalciferol production. Teriparatide is the active fragment (1–34) of endogenous human PTH.
Teriparatide and PTH mediate their biological effects via specific, G-protein-dependent, high-affinity membrane cell-surface receptors which are expressed on osteoblasts and renal tubular cells. Both molecules exert similar physiological effects on bone and kidneys. These effects lead to increases in bone strength of the spine, hip, and peripheral anatomic sites as well as a decreased fracture risk. The stimulation of bone resorption and formation is dose dependant.
Treatment with teriparatide increases 1,25-dihydroxycholecalciferol concentrations and decreases 25-hydroxycholecalciferol concentrations. This effect may contribute to the biological effects of teriparatide, for example, to stabilise calcium balance by increasing intestinal calcium absorption and renal calcium conservation.
Clinical efficacy
Risk Factors
Independent risk factors, e.g. low BMD, age, previous fracture, family history of hip fractures, high bone turnover, and low body mass index should be considered in order to identify women and men at increased risk of osteoporotic fractures who could benefit from treatment.
Premenopausal women with glucocorticoid-induced osteoporosis should be considered at high risk for fracture if they have a prevalent fracture or a combination of risk factors that place them at high risk for fracture (e.g. low bone density, sustained high dose glucocorticoid therapy, high underlying disease activity, low sex steroid levels).
Postmenopausal osteoporosis
The pivotal study included 1637 postmenopausal women (mean age 69.5 years). At baseline, 90% of the patients had one or more vertebral fractures and on average vertebral BMD was 0.82 g/cm2 (equivalent to a T-score = –2.6).

All patients were offered 1000 mg calcium and at least 400 IU vitamin D per day. Results from up to 24 months (median 19 months) treatment with FORSTEO demonstrated statistically significant fracture reduction (see table below); to prevent one or more new vertebral fracture, 11 women had to be treated for a median of 19 months. After a median of 19 months of treatment, bone mineral density (BMD) had increased in the lumbar spine and total hip, respectively, by 9 % and 4 % compared with placebo (p<0.001).

a The incidence of vertebral fractures was assessed in 448 placebo and 444 teriparatide patients who had baseline and follow-up spine radiographs.
b p≤0.001 compared with placebo
c A significant reduction in the incidence of hip fractures has not been demonstrated d p≤0.025 compared with placebo.
In a post-treatment follow-up study, 1262 postmenopausal women from the pivotal trial were enrolled. The primary objective was to collect safety data of teriparatide. During this observational period, other osteoporosis treatments were allowed and additional assessment of vertebral fractures was performed. During a median of 18 months following discontinuation of teriparatide, there was a 41 % reduction (p=0.004) compared with placebo in the number of patients with a minimum of one new vertebral fracture.
In an open-label study, 503 postmenopausal women with severe osteoporosis and a fragility fracture within the previous 3 years (83 % had received previous osteoporosis therapy) were treated with teriparatide for up to 24 months. At 24 months, the mean increases from baseline in lumbar spine, total hip, and femoral neck BMD were 10.5%, 2.6%, and 3.9 % respectively. The mean increases in BMD from 18 to 24 months were 1.4%, 1.2%, and 1.6% at the lumbar spine, total hip, and femoral neck, respectively.
A 24-month, randomised, double-blind, comparator-controlled Phase 4 study included 1360 postmenopausal women with established osteoporosis; 680 subjects were randomised to teriparatide and 680 to oral risedronate 35 mg/week. At baseline, the women had a mean age of 72.1 years and a median of 2 prevalent vertebral fractures; 57.9% of patients had received previous bisphosphonate therapy and 18.8% took concomitant glucocorticoids during the study. The 24-month follow-up was completed by 1013 (74.5%) patients. The mean (median) cumulative dose of glucocorticoid was 474.3 (66.2) mg in the teriparatide and 898.0 (100.0) mg in the risedronate arm. The mean (median) vitamin D intake in the teriparatide and in the risedronate arm were 1433 IU/day (1400 IU/day) and 1191 IU/day (900 IU/day), respectively. For those subjects who had baseline and follow-up spine radiographs, the incidence of new vertebral fractures was 28/516 (5.4%) in teriparatide- and 64/533 (12.0%) in risedronate-treated patients (relative risk [95% CI] = 0.44 [0.29–0.68], P<0.0001). The cumulative incidence of pooled clinical fractures (clinical vertebral and non vertebral fractures) was 4.8% in teriparatide and 9.8% in risedronate-treated patients (hazard ratio [95% CI] = 0.48 [0.320.74], P=0.0009).
Male osteoporosis
In a clinical trial in men with hypogonadal (defined as low morning free testosterone or elevated FSH or LH) or idiopathic osteoporosis 437 patients (mean age 58.7 years) were enrolled. Baseline spinal and femoral neck BMD mean T-scores were –2.2 and –2.1, respectively.
At baseline, 35 % of patients had a vertebral fracture and 59 % had a non-vertebral fracture.
All patients were offered 1000 mg calcium and at least 400 IU vitamin D per day. Lumbar spine BMD significantly increased by 3 months. After 12 months, BMD had increased in the lumbar spine and total hip by 5 % and 1 %, respectively, compared with placebo. However, no significant effect on fracture rates was demonstrated.
Glucocorticoid-induced osteoporosis
The efficacy of teriparatide in men and women (N=428) receiving sustained systemic glucocorticoid therapy (≥ 5 mg prednisone for ≥ 3 months) was demonstrated in the 18-month primary phase of a 36 month, randomised, double-blind, comparator-controlled study (alendronate 10 mg/day). Twentyeight percent (28%) of patients had one or more radiographic vertebral fracture at baseline. All patients were offered 1000 mg calcium and 800 IU vitamin D per day.
This study included postmenopausal women (N=277), premenopausal women (N=67), and men (N=83). At baseline, the postmenopausal women had a mean age of 61 years, mean lumbar spine BMD T-score of –2.7, median prednisone equivalent dose of 7.5 mg/day, and 34% had one or more radiographic vertebral fractures; premenopausal women had a mean age of 37 years, mean lumbar spine BMD T-score of –2.5, median prednisone equivalent dose of 10 mg/day, and 9% had one or more radiographic vertebral fractures; and men had a mean age of 57 years, mean lumbar spine BMD T-score of –2.2, median prednisone equivalent dose of 10 mg/day, and 24% had one or more radiographic vertebral fractures.
Sixty-nine percent (69%) of the patients completed the 18-month primary phase. At the 18 month endpoint, teriparatide significantly increased lumbar spine BMD (7.2%) compared with alendronate (3.4%) (p<0.001). Teriparatide compared with alendronate increased BMD at the total hip (3.6% versus 2.2%, p<0.01), as well as at the femoral neck (3.7% versus 2.1 %, p<0.05). In patients treated with teriparatide, lumbar spine, total hip, and femoral neck BMD increased between 18 and 24 months by an additional 1.7%, 0.9%, and 0.4%, respectively.
At 36 months, analysis of spinal X-rays from 169 alendronate and 173 teriparatide treated patients showed that 13 (7.7%) patients in the alendronate and 3 (1.7%) patients in the teriparatide group (p=0.01) had experienced a new vertebral fracture. In addition, 15 of 214 patients (7.0 %) in the alendronate and 16 of 214 patients in the teriparatide group (7.5 %) had experienced a nonvertebral fracture (p=0.84).
In premenopausal women, the increase in BMD from baseline to the 18 month endpoint was significantly greater in the teriparatide compared with the alendronate group at the lumbar spine (4.2% versus –1.9%; p<0.001) and total hip (3.8% versus 0.9%; p=0.005). However, no significant effect on fracture rates was demonstrated.
Clinical safety
The most commonly reported adverse reactions in patients treated with teriparatide are nausea, pain in limb, headache and dizziness. Of patients in the teriparatide trials, 82.8% of the patients on teriparatide and 84.5% on placebo reported at least 1 adverse event.

Teriparatide increases serum uric acid concentrations. In clinical trials, 2.8% of patients on teriparatide and 0.7% on placebo had serum uric acid concentrations above the upper limit of normal. However, hyperuricemia did not result in an increase in gout, arthralgia, or urolithiasis.
In a large clinical trial, antibodies that cross-reacted with teriparatide were detected in 2.8% of women receiving teriparatide. Generally, antibodies were first detected following 12 months of treatment and diminished after withdrawal of therapy. There was no evidence of hypersensitivity reactions, allergic reactions, effects on serum calcium, or effects on BMD response.
As regards overdose the effects that might be expected include delayed hypercalcaemia and risk of orthostatic hypotension; nausea, vomiting, dizziness, and headache can also occur. In post-marketing spontaneous reports, there have been cases of medication error where the entire contents of up to 800 µg of the teriparatide pen have been administered as a single dose. Transient events reported have included nausea, weakness / lethargy, and hypotension. In some cases, no adverse events occurred as a result of the overdose. No fatalities associated with overdose have been reported.
