4.1 Therapeutic indications

Hormone Replacement Therapy (HRT) for oestrogen deficiency symptoms in post- and peri-menopausal women. Prevention of osteoporosis in postmenopausal women at high risk of future fractures who are intolerant of, or contraindicated for, other medicinal products approved for the prevention of osteoporosis (see also Section 4.4).

The experience of treating women older than 65 years is limited.

4.2 Posology and method of administration

Posology

This product is a continuous sequential HRT. One orange tablet to be taken daily for the first 16 days, followed by one grey tablet for the next 12 days. A new cycle should then begin without any break. Therapy may start at any time in patients with established amenorrhoea or who are experiencing long intervals between spontaneous menses. In patients who are menstruating it is advised that therapy starts on the first day of bleeding. Patients changing from another cyclical or continuous sequential preparation should complete the cycle and may then change to Elleste Duet 2 mg without a break in therapy. Patients changing from a continuous combined preparation may start therapy at any time if amenorrhoea is established, or otherwise start on the first day of bleeding.

Elleste Duet tablets are available in two strengths: Elleste Duet 1 mg (containing 1 mg estradiol and 1 mg norethisterone acetate) and Elleste Duet 2 mg (containing 2 mg estradiol and 1 mg norethisterone acetate). For initiation and continuation of treatment of post- and peri-menopausal symptoms, the lowest effective dose for the shortest duration (see also Section 4.4) should be used.

Missed Tablet: If a tablet is missed it should be taken within 12 hours of when normally taken; otherwise the tablet should be discarded, and the usual tablet should be taken the following day. If a tablet is missed there is an increased likelihood of breakthrough bleeding or spotting.

Elderly

There are no special dosage requirements for elderly patients.

Paediatric population

Not to be used in children.

Method of administration

For oral use.

4.3 Contraindications

Known, past or suspected breast cancer;

Known or suspected oestrogen-dependent malignant tumours (e.g. endometrial cancer);

Undiagnosed genital bleeding;

Untreated endometrial hyperplasia;

Previous or current venous thromboembolism (deep venous thrombosis, pulmonary embolism);

Known thrombophilic disorders (e.g. protein C, protein S, or antithrombin deficiency, see Section 4.4);

Active or recent arterial thromboembolic disease (e.g. angina, myocardial infarction);

Acute liver disease, or a history of liver disease as long as liver function tests have failed to return to normal;

Hypersensitivity to the active substances or to any of the excipients listed in Section 6.1;

Porphyria.

4.4 Special warnings and precautions for use

For the treatment of postmenopausal symptoms, HRT should only be initiated for symptoms that adversely affect quality of life. In all cases, a careful appraisal of the risks and benefits should be undertaken at least annually and HRT should only be continued as long as the benefit outweighs the risk.

Evidence regarding the risks associated with HRT in the treatment of premature menopause is limited. Due to the low level of absolute risk in younger women, however, the balance of benefits and risks for these women may be more favourable than in older women.

Medical Examination/Follow Up

Before initiating or reinstituting HRT, a complete personal and family medical history should be taken. Physical (including pelvic and breast) examination should be guided by this and by the Sections 4.3 Contraindications and 4.4 Special warnings and precautions for use. During treatment, periodic check-ups are recommended of a frequency and nature adapted to the individual woman. Women should be advised what changes in their breasts should be reported to their doctor or nurse (see 'Breast Cancer' below). Investigations, including appropriate imaging tools, e.g. mammography, should be carried out in accordance with currently accepted screening practices, modified to the clinical needs of the individual.

Conditions Which Need Supervision

If any of the following conditions are present, have occurred previously, and/or have been aggravated during pregnancy or previous hormone treatment, the patient should be closely supervised. It should be taken into account that these conditions may recur or be aggravated during treatment with Elleste Duet 2 mg, in particular:

- Leiomyoma (uterine fibroids) or endometriosis

- Risk factors for thromboembolic disorders (see below)

- Risk factors for oestrogen dependent tumours, e.g. 1st degree heredity for breast cancer

- Hypertension

- Liver disorders (e.g. liver adenoma)

- Diabetes mellitus with or without vascular involvement

- Cholelithiasis

- Migraine or (severe) headache

- Systemic lupus erythematosus

- A history of endometrial hyperplasia (see below)

- Epilepsy

- Asthma

- Otosclerosis

Reasons for Immediate Withdrawal of Therapy:

Therapy should be discontinued in case a contra-indication is discovered and in the following situations:

- Jaundice or deterioration in liver function

- Significant increase in blood pressure

- New onset of migraine-type headache

- Pregnancy

Endometrial Hyperplasia and Carcinoma

In women with an intact uterus, the risk of endometrial hyperplasia and carcinoma is increased when oestrogens are administered alone for prolonged periods. The reported increase in endometrial cancer risk among oestrogen-only users varies from 2-to 12-fold greater compared with non-users, depending on the duration of treatment and oestrogen dose (see Section 4.8). After stopping treatment, risk may remain elevated for at least 10 years.

The addition of a progestogen cyclically for at least 12 days per month/per 28 day cycle or continuous combined oestrogen-progestogen therapy in non-hysterectomised women prevents the excess risk associated with oestrogen-only HRT.

Break-through bleeding and spotting may occur during the first months of treatment. If break-through bleeding or spotting appears after some time on therapy, or continues after treatment has been discontinued, the reason should be investigated, which may include endometrial biopsy to exclude endometrial malignancy.

Breast Cancer

The overall evidence suggests an increased risk of breast cancer in women taking combined oestrogen-progestogen and possibly also oestrogen-only HRT, that is dependent on the duration of taking HRT.

Combined oestrogen-progestogen therapy

• The randomised placebo-controlled trial the (Women's Health Initiative study (WHI), and epidemiological studies are consistent in finding an increased risk of breast cancer in women taking combined oestrogen-progestogen for HRT that becomes apparent after about 3 years (see Section 4.8)

Oestrogen-only therapy

• The WHI trial found no increase in the risk of breast cancer in hysterectomised women using oestrogen-only HRT. Observational studies have mostly reported a small increase in risk of having breast cancer diagnosed that is substantially lower than that found in users of oestrogen-progestogen combinations (see Section 4.8).

The excess risk becomes apparent within a few years of use but returns to baseline within a few (at most five) years after stopping treatment.

HRT, especially oestrogen-progestogen combined treatment, increases the density of mammographic images which may adversely affect the radiological detection of breast cancer.

Ovarian Cancer

▪ Ovarian cancer is much rarer than breast cancer. Epidemiological evidence from a large meta-analysis suggests a slightly increased risk in women taking oestrogen-only or combined oestrogen-progestagen HRT, which becomes apparent within 5 years of use and diminishes over time after stopping.

Some other studies, including the WHI trial, suggest that the use of combined HRTs may be associated with a similar, or slightly smaller risk (see Section 4.8).

Venous Thromboembolism

▪ HRT is associated with a 1.3-3 fold risk of developing venous thromboembolism (VTE), i.e. deep vein thrombosis or pulmonary embolism. The occurrence of such an event is more likely in the first year of HRT than later (see Section 4.8).

▪ Patients with known thrombophilic states have an increased risk of VTE and HRT may add to this risk. HRT is therefore contraindicated in these patients (see Section 4.3).

▪ Generally recognised risk factors for VTE include use of oestrogens, older age, major surgery, prolonged immobilization, obesity (BMI>30 kg/m2), pregnancy/postpartum period, systemic lupus erythematosus (SLE) and cancer. There is no consensus about the possible role of varicose veins in VTE.

▪ As in all postoperative patients, prophylactic measures need to be considered to prevent VTE following surgery. If prolonged immobilisation is to follow elective surgery temporarily stopping HRT 4 to 6 weeks earlier is recommended. Treatment should not be restarted until the woman is completely mobilised.

▪ In women with no personal history of VTE but with a first degree relative with a history of thrombosis at young age, screening may be offered after careful counselling regarding its limitations (only a proportion of thrombophilic defects are identified by screening). If a thrombophilic defect is identified which segregates with thrombosis in family members or if the defect is 'severe' (e.g, antithrombin, protein S, or protein C deficiencies or a combination of defects) HRT is contraindicated.

▪ Women already on chronic anticoagulant treatment require careful consideration of the benefit-risk of use of HRT.

▪ If VTE develops after initiating therapy, the drug should be discontinued. Patients should be told to contact their doctors immediately when they are aware of a potential thromboembolic symptom (e.g., painful swelling of a leg, sudden pain in the chest, dyspnoea).

Coronary Artery Disease (CAD)

▪ There is no evidence from randomised controlled trials of protection against myocardial infarction in women with or without existing CAD who received combined oestrogen-progestogen or oestrogen-only HRT.

Combined oestrogen-progestogen therapy

The relative risk of CAD during use of combined oestrogen-progestogen HRT is slightly increased. As the baseline absolute risk of CAD is strongly dependent on age, the number of extra cases of CAD due to oestrogen-progestogen use is very low in healthy women close to menopause, but will rise with more advanced age.

Oestrogen-only

Randomised controlled data found no increased risk of CAD in hysterectomised women using oestrogen-only therapy.

Ischaemic Stroke

▪ Combined oestrogen-progestogen and oestrogen-only therapy are associated with an up to 1.5-fold increase in risk of ischaemic stroke. The relative risk does not change with age or time since menopause. However, as the baseline risk of stroke is strongly age-dependent, the overall risk of stroke in women who use HRT will increase with age (see Section 4.8).

Hypothyroidism

▪ Patients who require thyroid hormone replacement therapy should have their thyroid function monitored regularly while on HRT to ensure that thyroid hormone levels remain in an acceptable range.

Angioedema

▪ Oestrogens may induce or exacerbate symptoms of angioedema, in particular in women with hereditary angioedema.

Other Conditions

▪ Oestrogens may cause fluid retention and therefore patients with cardiac or renal dysfunction should be carefully observed.

▪ Women with pre-existing hypertriglyceridaemia should be followed closely during oestrogen replacement or hormone replacement therapy, since rare cases of large increases of plasma triglycerides leading to pancreatitis have been reported with oestrogen therapy in this condition.

▪ Oestrogens increase thyroid binding globulin (TBG), leading to increased circulating total thyroid hormone, as measured by protein-bound iodine (PBI), T4 levels (by column or by radio-immunoassay) or T3 levels (by radio-immunoassay). T3 resin uptake is decreased, reflecting the elevated TBG. Free T4 and free T3 concentrations are unaltered. Other binding proteins may be elevated in serum, i.e. corticoid binding globulin (CBG), sex-hormone-binding globulin (SHBG) leading to increased circulating corticosteroids and sex steroids, respectively. Free or biological active hormone concentrations are unchanged. Other plasma proteins may be increased (angiotensinogen/renin substrate, alpha-1-antitrypsin, ceruloplasmin).

▪ HRT does not improve cognitive function. There is some evidence of increased risk of probable dementia in women who start using continuous combined or oestrogen-only HRT after the age of 65.

▪ Elleste Duet 2mg Tablets contain sunset yellow colouring (E110) which can cause allergic-type reactions, including asthma. This allergy is more common in people who are allergic to aspirin.

▪ Patients with rare hereditary disorders of galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption should not take this medicine.

4.5 Interaction with other medicinal products and other forms of interaction

The metabolism of oestrogens and progestogens may be increased by concomitant use of substances known to induce drug-metabolising enzymes, specifically cytochrome P450 enzymes, such as anticonvulsants (e.g. phenobarbital, phenytoin, carbamazepine) and anti-infectives (e.g. rifampicin, rifabutin, nevirapine, efavirenz).

Ritonavir, telaprevir and nelfinavir, although known as strong inhibitors, by contrast exhibit inducing properties when used concomitantly with steroid hormones.

Herbal preparations containing St John's Wort (Hypericum Perforatum) may induce the metabolism of oestrogens and progestogens.

Clinically, an increased metabolism of oestrogens and progestogens may lead to decreased effect and changes in the uterine bleeding profile.

Some laboratory tests can be influenced by oestrogens, such as tests for thyroid function (see Section 4.4).

4.6 Fertility, pregnancy and lactation

Pregnancy:

Elleste Duet 2 mg is not indicated during pregnancy. If pregnancy occurs during medication with Elleste Duet 2 mg treatment should be withdrawn immediately.

Clinically, data on a limited number of exposed pregnancies indicate no adverse effects of norethisterone acetate on the foetus. At doses higher than normally used in OC and HRT formulations masculinisation of female foetuses was observed.

The results of most epidemiological studies to date relevant to inadvertent foetal exposure to combinations of oestrogens and progestogens indicate no teratogenic or foetotoxic effect.

Breast-feeding:

Elleste Duet 2 mg is not indicated during breast-feeding.

4.7 Effects on ability to drive and use machines

Elleste Duet 2 mg Tablets have no or negligible influence on the ability to drive and use machines.

4.8 Undesirable effects

Breast Cancer Risk

• An up to 2-fold increased risk of having breast cancer diagnosed is reported in women taking combined oestrogen-progestogen therapy for more than 5 years.

• Any increased risk in users of oestrogen-only therapy is substantially lower than that seen in users of oestrogen-progestogen combinations.

• The level of risk is dependent on the duration of use (see Section 4.4).

• Results of the largest randomised placebo-controlled trial (WHI-study) and largest epidemiological study (MWS) are presented.

Endometrial Cancer Risk

Postmenopausal women with a uterus

The endometrial cancer risk is about 5 in every 1000 women with an uterus not using HRT.

In women with a uterus, use of oestrogen-only HRT is not recommended because it increases the risk of endometrial cancer (see Section 4.4).

Depending on the duration of oestrogen-only use and oestrogen dose, the increase in risk of endometrial cancer in epidemiology studies varied from between 5 and 55 extra cases diagnosed in every 1000 women between the ages of 50 and 65.

Adding a progestogen to oestrogen-only therapy for at least 12 days per cycle can prevent this increased risk. In the Million Women Study the use of five years of combined (sequential or continuous) HRT did not increase risk of endometrial cancer (RR of 1.0 (0.8-1.2)).

Ovarian Cancer

Use of oestrogen-only or combined oestrogen-progestogen HRT has been associated with a slightly increased risk of having ovarian cancer diagnosed (see Section 4.4).

A meta-analysis from 52 epidemiological studies reported an increased risk of ovarian cancer in women currently using HRT compared to women who have never used HRT (RR 1.43, 95% CI 1.31-1.56). For women aged 50 to 54 years taking 5 years of HRT, this results in about 1 extra case per 2000 users. In women aged 50 to 54 who are not taking HRT, about 2 women in 2000 will be diagnosed with ovarian cancer over a 5-year period.

Risk of Venous Thromboembolism

HRT is associated with a 1.3-3-fold increased relative risk of developing venous thromboembolism (VTE), i.e. deep vein thrombosis or pulmonary embolism. The occurrence of such an event is more likely in the first year of using HT (see Section 4.4). Results of the WHI studies are presented:

Risk of Coronary Artery Disease

The risk of coronary artery disease is slightly increased in users of combined oestrogen-progestogen HRT over the age of 60 (see Section 4.4).

Risk of Ischaemic Stroke

• The use of oestrogen-only and oestrogen - progestogen therapy is associated with an up to 1.5 fold increased relative risk of ischaemic stroke. The risk of haemorrhagic stroke is not increased during use of HRT.

• This relative risk is not dependent on age or on duration of use, but as the baseline risk is strongly age-dependent, the overall risk of stroke in women who use HRT will increase with age, see Section 4.4.

- dry eyes

- tear film composition changes

Reporting of suspected adverse reactions

Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme at: www.mhra.gov.uk/yellowcard.

4.9 Overdose

Symptoms of over dosage with oral oestrogens are breast tenderness, nausea, vomiting and/or metrorrhagia. Over dosage of progestogens may lead to a depressive mood, fatigue, acne and hirsutism. If over dosage is discovered within two or three hours and is so large that treatment seems desirable, gastric lavage can be considered. There are no specific antidotes for over dosage and further treatment should be symptomatic.

5. Pharmacological properties
5.1 Pharmacodynamic properties

Pharmacotherapeutic group: Progestogens and oestrogens, sequential preparations, norethisterone and oestrogen.

ATC Code: G03FB05

Estradiol

The active ingredient, synthetic 17β-estradiol, is chemically and biologically identical to endogenous human estradiol. It substitutes for the loss of oestrogen production in menopausal women, and alleviates menopausal symptoms.

Oestrogens prevent bone loss following menopause or ovariectomy. Oestrogen deficiency at menopause is associated with an increasing bone turnover and decline in bone mass. The effect of oestrogens on the bone mineral density is dose-dependent. Protection appears to be effective for as long as treatment is continued. After discontinuation of HRT, bone mass is lost at a rate similar to that in untreated women.

Evidence from the WHI trial and meta-analysed trials shows that current use of HRT, alone or in combination with a progestogen – given to predominantly healthy women – reduces the risk of hip, vertebral, and other osteoporotic fractures. HRT may also prevent fractures in women with low bone density and/or established osteoporosis, but the evidence for that is limited.

Norethisterone acetate

As oestrogens promote the growth of the endometrium, unopposed oestrogens increase the risk of endometrial hyperplasia and cancer. The addition of a progestogen greatly reduces the oestrogen-induced risk of endometrial hyperplasia in non-hysterectomised women.

5.2 Pharmacokinetic properties

Pharmacokinetic parameters for Elleste Duet 2 mg (2 mg estradiol + 1 mg norethisterone tablets) are provided in the table below. The data were obtained from an open label, two way crossover pharmacokinetic study in which treatment was administered for 7 days to achieve steady state (n=24).

Estradiol

Readily and fully absorbed from the GI tract when given orally, peak levels are generally observed 3-6 hours after ingestion, but by 24 hours concentrations have returned to baseline.

Estradiol is converted to estrone and estriol primarily in the liver. These are excreted into the bile and undergo enterohepatic recirculation and further degradation before being excreted in the urine (90-95%) as biologically inactive glucuronide and sulphate conjugates or in the faeces (5-10%), mostly unconjugated.

Norethisterone acetate

Norethisterone acetate is absorbed from GI tract and its effects last for at least 24 hours. Maximum blood concentrations are generally reached 1-4 hours after administration. Norethisterone acetate undergoes first pass effect, being transformed to norethisterone which is then metabolised and excreted mainly in the urine as glucuronide and sulphate conjugates.

5.3 Preclinical safety data

Both estradiol and norethisterone acetate have been shown to induce adverse effects in preclinical reproductive toxicity studies. Chiefly, estradiol showed embryotoxic effects and induced anomalies in urogenital tract development, e.g. feminisation of male foetuses in high doses. Norethisterone acetate showed embryotoxic effects and induced anomalies in urogenital tract development. In mice, additional anomalies in non-urogenital foetal development, including hydrocephalus and clubfoot, have been detected.

Long-term, continuous administration of natural and synthetic oestrogens in certain animal species increases the frequency of carcinomas of the breast, uterus, cervix, vagina, testis, and liver. Long-term, continuous administration of norethisterone in certain animal species increases the frequency of tumours of the hypophysis and ovary in females, and of liver and breast in males.
