(See Section 5.1)

4.2. Posology and method of administration

Posology

Prostate Cancer: The recommended dose is 11.25 mg presented as a three month depot injection and administered as a single subcutaneous injection at intervals of three months. The majority of patients will respond to this dosage. PROSTAP 3 therapy should not be discontinued when remission or improvement occurs. As with other drugs administered regularly by injection, the injection site should be varied periodically.

Response to PROSTAP 3 therapy should be monitored by clinical parameters and by measuring prostate-specific antigen (PSA) and testosterone serum levels. Clinical studies with leuprorelin acetate have shown that testosterone levels increased during the first 4 days of treatment in the majority of non-orchidectomised patients. They then decreased and reached castrate levels by 2-4 weeks. Once attained, castrate levels were maintained as long as drug therapy continued. If a patient's response appears to be sub-optimal, then it would be advisable to confirm that serum testosterone levels have reached or are remaining at castrate levels. Transient increases in acid phosphatase levels sometimes occur early in the treatment period but usually return to normal or near normal values by the 4th week of treatment.

In patients treated with GnRH analogues for prostate cancer, treatment is usually continued upon development of castrate-resistant prostate cancer. Reference should be made to relevant guidelines.

Endometriosis: The recommended dose is 11.25 mg administered as a single intramuscular injection every 3 months for a period of up to 6 months only. Treatment should be initiated during the first 5 days of the menstrual cycle.

In women receiving GnRH analogues for the treatment of endometriosis, the addition of hormone replacement therapy (HRT - an estrogen and progestogen) has been shown to reduce bone mineral density loss and vasomotor symptoms. Therefore if appropriate, HRT may be co-administered with PROSTAP 3 taking into account the risks and benefits of each treatment.

Advanced breast cancer:

The recommended dose is 11.25 mg administered as a single subcutaneous injection every 3 months.

Early breast cancer:

The recommended dose is 11.25 mg administered as a single subcutaneous injection every 3 months in combination with tamoxifen or an aromatase inhibitor.

In women receiving chemotherapy, leuprorelin should be commenced after completion of chemotherapy, once pre-menopausal status has been confirmed (see section 4.4).

The recommended treatment duration for adjuvant treatment in combination with other hormonotherapy is up to 5 years.

In combination with aromatase inhibitor for advanced and early breast cancer:

Treatment with leuprorelin must be initiated at least 6-8 weeks before starting aromatase inhibitor treatment. A minimum of one injection of PROSTAP 3 should be administered before commencement of aromatase inhibitor treatment.

Ovarian suppression should be confirmed by low blood concentrations of FSH and estradiol prior to starting aromatase inhibitor treatment and measurements should be repeated every three months during combination therapy with leuprorelin and an aromatase inhibitor (see Section 4.4).

During treatment with an aromatase inhibitor, leuprorelin must not be interrupted to avoid rebound increases in circulating estrogens in premenopausal women.

PROSTAP 3 should not be used for preservation of ovarian function (see Section 5.1).

Elderly: As for adults.

Paediatric population:

The treatment of children with leuprorelin acetate should be under the overall supervision of the paediatric endocrinologist.

The dosing scheme needs to be adapted individually.

The recommended starting dose is dependent on the body weight.

Children with a body weight ≥ 20 kg

1 ml (11.25 mg leuprorelin acetate) suspension of 130.0 mg sustained-release microcapsules in 1 ml vehicle solution are administered every 3 months as a single subcutaneous injection.

Children with a body weight < 20 kgIn these rare cases the following dosage should be administered according to the clinical activity of the central precocious puberty:

0.5 ml (5.625 mg leuprorelin acetate) suspension of 130.0 mg sustained-release microcapsules in 1 ml vehicle solution are administered every 3 months as a single subcutaneous injection.

The remainder of the suspension should be discarded. The child's weight gain should be monitored.

Depending on the activity of the central precocious puberty, it may be necessary to increase the dosage in the presence of inadequate suppression (clinical evidence e.g. spotting or inadequate gonadotropin suppression in the GnRH test). The minimal effective 3-monthly dose to be administered should then be determined by means of the GnRH test.

Sterile abscesses at the injection site often occurred when leuprorelin acetate was administered intramuscularly at higher than the recommended dosages. Therefore, in such cases, the medicinal product should be administered subcutaneously (see 4.4).

It is recommended to use the lowest volumes possible for injections in children in order to decrease the inconvenience which is associated with the intramuscular/subcutaneous injection.

The duration of treatment depends on the clinical parameters at the start of treatment or during the course of treatment (final height prognosis, growth velocity, bone age and/or bone age acceleration) and is decided by the treating paediatrician together with the legal guardian and, if appropriate, the treated child. The bone age should be monitored during treatment at 6-12 month intervals.

In girls with bone maturation of older than 12 years and boys with bone maturation of older than 13 years discontinuation of treatment should be considered taking into account the clinical parameters.

In girls, pregnancy should be excluded before the start of treatment. The occurrence of pregnancy during treatment cannot be generally excluded. In such cases, medical advice should be sought.

Note:

The administration interval should be 90 ± 2 days in order to prevent the recurrence of precocious puberty symptoms.

Method of Administration

Read this Instructions For Use before injecting.

This product should be prepared, reconstituted and administered only by healthcare professionals who are familiar with these procedures.

Warnings

Wash hands before opening the syringe package.

Hold syringe upright (with needle side up) throughout entire preparation to prevent leakage.

Use immediately after mixing as the suspension settles out very quickly following reconstitution.

Check the expiration date printed on the syringe label, and check the powder and diluent in the syringe barrel. The powder should be white and dry, and the diluent should be clear. Inspect the syringe for any damage.

• Do not use the syringe if the expiration date has passed.

• Do not use the syringe if the powder appears clumped or caked.

• Do not use the syringe if powder or diluent appear discoloured.

• Do not use the syringe if any part of it is damaged.

Step 1. Attach plunger and tighten needle

• Remove the plunger from the package.

• Screw the plunger rod into the bottom of the syringe until the end stopper begins to rotate.

• Do not twist or pull the plunger rod back once it has been attached.

• Without removing the needle cap, twist the needle to the right (clockwise) to ensure it is secured tightly.

• Do not remove needle cap until you are ready to inject.

Step 2. Release diluent

• Holding the syringe upright, release the diluents by slowly pushing the plunger until the middle stopper reaches the blue line in the middle of the syringe. You should see the diluent flowing into the interior chamber above the blue line.

• Do not push the plunger too quickly or push past the blue line as these actions may cause leaking.

• Do not withdraw plunger again.

Step 3. Mix suspension

• Gently tap the syringe against the palm of your hand to mix the powder and diluent until it forms a uniform suspension. When properly mixed, the suspension should appear milky with no visible lumps.

• Note: If particles stick to the stopper during mixing, dislodge them by gently tapping the syringe with your finger.

• Avoid hard tapping or shaking to prevent the generation of bubbles.

• Use immediately after mixing as the suspension settles out very quickly following reconstitution.

Step 4. Remove needle cap and prime syringe

• Remove the needle cap by pulling it straight upwards.

• Do not twist the needle cap.

• Prime the syringe by pushing the plunger upward until all air has been expelled from the syringe.

Step 5. Inject

• The syringe is now ready for injection. Use immediately as the suspension settles out very quickly following reconstitution.

• At the time of injection, check the direction of the safety device (with round mark pointing towards you) and inject the entire contents of the syringe subcutaneously or intramuscularly as you would for a normal injection.

Step 6. Activate safety device

• When injection is complete, withdraw the needle from the patient. Immediately activate the safety device by pressing upward from just below the arrow until a “CLICK” is heard or felt and the needle is fully covered.

Step 7. Dispose of syringe

• Dispose of the used device in the appropriate sharps container in accordance with your local standard procedure.

4.3. Contraindications

Hypersensitivity to leuprorelin, any of the excipients or to other synthetic gonadotrophin releasing hormone (Gn-RH) analogues or Gn-RH derivatives.

Women: PROSTAP 3 is contra-indicated in women who are or may become pregnant while receiving the drug. PROSTAP 3 should not be used in women who are breastfeeding or have undiagnosed abnormal vaginal bleeding. See section 4.4.

In the pre- and perimenopausal breast cancer setting: Initiation of aromatase inhibitor treatment before adequate ovarian suppression with leuprorelin has been achieved (see sections 4.2 and 4.4).

Men: There are no other known contra-indications to the use of PROSTAP 3 in men.

In girls with central precocious puberty:

- Pregnancy and breastfeeding

- Undiagnosed vaginal bleeding.

4.4. Special warnings and precautions for use

PROSTAP 3 injectable suspension must be prepared at the time of use and, after reconstitution, used immediately.

PROSTAP 3 contains sodium. This medicine contains less than 1 mmol sodium (23 mg) per injection, this is to say it is essentially 'sodium free'.

Depression: There is an increased risk of incident depression (which may be severe) in patients undergoing treatment with GnRH agonists, such as leuprorelin. Patients should be informed and monitored accordingly and treated as appropriate if symptoms occur.

Seizure: Postmarketing reports of seizures have been observed in patients treated with leuprorelin acetate and these events have been reported in both children and adults, and in those with or without a history of epilepsy, seizure disorders or risk disorders for seizures.

Idiopathic intracranial hypertension

Idiopathic intracranial hypertension (pseudotumor cerebri) has been reported in patients receiving leuprorelin. Patients should be warned for signs and symptoms of idiopathic intracranial hypertension, including severe or recurrent headache, vision disturbances and tinnitus. If idiopathic intracranial hypertension occurs, discontinuation of leuprorelin should be considered.

Severe cutaneous adverse reactions

Severe cutaneous adverse reactions (SCARs) including Stevens-Johnson syndrome (SJS), and Toxic epidermal necrolysis (TEN) which can be life-threatening or fatal, have been reported in association with leuprorelin treatment. At the time of prescription patients should be advised of the signs and symptoms and monitored closely for severe skin reactions. If signs and symptoms suggestive of these reactions appear, leuprorelin should be withdrawn immediately and an alternative treatment considered (as appropriate).

Metabolic changes associated with GnRH agonist may also include fatty liver disease.

Adults: Epidemiological data have shown that during androgen deprivation therapy in males and estrogen deprivation therapy in females, changes in the metabolic condition (e.g. reduction in glucose tolerance or aggravation of pre-existing diabetes) as well as an increased risk for cardiovascular diseases may occur. However, prospective data did not confirm a link between treatment with GnRH analogues and an increase in cardiovascular mortality. Patients at high risk for metabolic changes or syndrome, or cardiovascular diseases should be appropriately monitored. Diabetic patients may require more frequent monitoring of blood glucose during treatment with PROSTAP 3.

Hepatic dysfunction and jaundice with elevated liver enzyme have been reported. Therefore, close observation should be made and appropriate measures taken if necessary.

Spinal fracture, paralysis and hypotension have been reported.

Bone mineral loss: Long-term estrogen deprivation either by bilateral oophorectomy, ovarian ablation or administration of GnRH analogues, or long-term androgen deprivation either by bilateral orchiectomy or administration of GnRH analogues is associated with increased risk of bone mineral loss which, in patients with additional risk factors, may lead to osteoporosis and an increased risk of bone fracture (see section 4.8).

An induced hypo-estrogenic state results in a loss in bone density over the course of treatment, some of which may not be reversible e.g. the extent of bone demineralisation due to hypo-estrogenaemia is proportional to time. The generally accepted level of bone loss with GnRH analogues such as PROSTAP 3 is 5%. In clinical studies with PROSTAP 3 the levels varied between 2.3% and 15.7% depending on the method of measurement. During one treatment period e.g. six months, this bone loss should not be important.

In patients with major risk factors for decreased bone mineral content such as chronic alcohol and/or tobacco use, strong family history of osteoporosis, or chronic use of drugs that can reduce bone mass such as anticonvulsants or corticosteroids, PROSTAP SR therapy may pose an additional risk. In these patients, the risks and benefits must be weighed carefully before therapy with PROSTAP 3 is instituted. This is particularly important in women with uterine fibroids where age related bone loss may have already begun to occur.

Men: In the initial stages of therapy, a transient rise in levels of testosterone, dihydrotestosterone and acid phosphatase may occur. In some cases, this may be associated with a "flare" or exacerbation of the tumour growth resulting in temporary deterioration of the patient's condition. These symptoms usually subside on continuation of therapy. "Flare" may manifest itself as systemic or neurological symptoms in some cases.

In order to reduce the risk of “flare”, an anti-androgen may be administered beginning 3 days prior to leuprorelin acetate therapy and continuing for the first two to three weeks of treatment. This has been reported to prevent the sequelae of an initial rise in serum testosterone. If an anti-androgen is used over a prolonged period, due attention should be paid to the contra-indications and precautions associated with its extended use.

In the rare event of an abscess occurring at the injection site, testosterone level should be monitored as there may be inadequate absorption of leuprorelin from the depot formulation.

Patients at risk of or with ureteric obstruction or spinal cord compression due to metastasis, should be considered carefully and closely supervised in the first few weeks of treatment as bone pain, weakness of the lower extremities and paraesthesia (as neurologic symptom) may occur. These patients should be considered for prophylactic treatment with anti-androgens. Should urological/neurological complications occur, these should be treated by appropriate specific measures.

Whilst the development of pituitary adenomas has been noted in chronic toxicity studies at high doses in some animal species, this has not been observed in long term clinical studies with leuprorelin acetate.

Androgen deprivation therapy may prolong the QT interval.

In patients with a history of or risk factors for QT prolongation and in patients receiving concomitant medicinal products that might prolong the QT interval (see section 4.5) physicians should assess risk and benefits including the potential for Torsade de pointes prior to initiating treatment with PROSTAP 3.

Women:

Initial increase in sex steroids

During the early phase of therapy, sex steroids temporarily rise above baseline because of the physiological effect of the drug. Therefore, a worsening of clinical signs and symptoms may be observed during the initial days of therapy, but these will dissipate with continued therapy.

Endometriosis

When receiving GnRH analogues for the treatment of endometriosis, the duration of administration of leuprorelin acetate should be limited to 6 months, as its use is associated with an increased risk of bone mineral loss (see Bone Mineral loss, section 4.4). The addition of HRT (an estrogen and progestogen) has been shown to reduce bone mineral density loss and vasomotor symptoms. Therefore, if appropriate, HRT may be co-administered with leuprorelin acetate, taking into account the risks and benefits of each medicinal product, for up to 6 months if clinically appropriate. If it is necessary to resume administration of leuprorelin acetate, changes in bone parameters should be closely followed.

Abnormal bleeding

In women with submucous fibroids there have been reports of severe vaginal bleeding following administration of PROSTAP 3 as a consequence of the acute degeneration of the fibroids. Patients should be warned of the possibility of abnormal bleeding or pain in case earlier surgical intervention is required.

Cervical resistance

PROSTAP 3 may cause an increase in uterine cervical resistance, which may result in difficulty in dilating the cervix for intrauterine surgical procedures.

Breast cancer

Advanced and early breast cancer:

In order to ensure adequate ovarian suppression in pre- and perimenopausal women, treatment with leuprorelin should be administered for at least 6-8 weeks prior to commencement of an aromatase inhibitor, and 3 monthly leuprorelin injections should be administered on schedule and without interruption throughout aromatase inhibitor treatment.

Women who are premenopausal at breast cancer diagnosis and who become amenorrhoeic following chemotherapy may or may not have continued estrogen production from the ovaries. Irrespective of menstrual status, premenopausal status should be confirmed following chemotherapy and before commencement of leuprorelin, by blood concentrations of estradiol and FSH within the reference ranges for premenopausal women, in order to avoid unnecessary treatment with leuprorelin in the event of a chemotherapy-induced menopause.

Following commencement of leuprorelin, it is important to confirm adequate ovarian suppression (gonadotrophin analogue- induced menopause) by serial assessment of circulating FSH, and estradiol if this subset of women is to be considered for therapy with an aromatase inhibitor, in accordance with current clinical practice recommendations. Accordingly, ovarian suppression should be confirmed by low blood concentrations of FSH and estradiol prior to starting aromatase inhibitor treatment and measurements should be repeated every three months during combination therapy with leuprorelin and an aromatase inhibitor. This is to avoid aromatase inhibitor-induced rebound increase in circulating estrogen, with consequential implications for the breast cancer. Of note, circulating FSH levels are lowered in response to gonadotrophin analogue-induced ovarian suppression (induced menopause), unlike in a natural menopause where FSH levels are elevated.

Patients who have discontinued leuprorelin treatment should also discontinue aromatase inhibitors within 3 months of the last PROSTAP 3 administration.

Particular attention should also be paid to the prescribing information of co-administered medicinal products, such as aromatase inhibitors, tamoxifen, CDK4/6 inhibitors, for relevant safety information when administered in combination with leuprorelin.

Bone mineral density should be assessed before starting treatment with leuprorelin, particularly in women who have additional risk factors for osteoporosis. These patients should be closely monitored and treatment for, or prophylaxis of, osteoporosis should be initiated when appropriate

The risk of musculoskeletal disorders (including joint or musculoskeletal pain) when a GnRH agonist is used in combination with either an aromatase inhibitor or tamoxifen is approximately 89% with the aromatase inhibitor and approximately 76% with tamoxifen.

Hypertension has been reported as a targeted adverse event at a very common frequency with GnRH agonist in combination with either exemestane or tamoxifen.

Premenopausal women with breast cancer receiving GnRH agonist in combination with either exemestane or tamoxifen should have regular monitoring of cardiovascular risk factors and blood pressure.

Hyperglycaemia and diabetes were reported as targeted adverse events at a common frequency with a GnRH agonist in combination with either exemestane or tamoxifen. Premenopausal women with breast cancer receiving a GnRH agonist in combination with either exemestane or tamoxifen should have regular monitoring of risk factors for diabetes with blood glucose monitoring on a regular basis and appropriate anti-diabetic treatment initiated, if appropriate, according to national guidelines.

Depression has been reported to occur in approximately 50% of patients treated with a GnRH agonist in combination with either tamoxifen or exemestane, but less than 5% of patients had severe depression (grade 3-4). Patients should be informed accordingly and treated as appropriate if symptoms occur. Patients with known depression or depression history should be carefully monitored during therapy.

Treatment of premenopausal women with endocrine responsive early stage breast cancer with leuprorelin in combination with tamoxifen or an aromatase inhibitor should follow a careful individual appraisal of the risks and benefits.

Precautions

Men: Patients with urinary obstruction and patients with metastatic vertebral lesions should begin PROSTAP 3 therapy under close supervision for the first few weeks of treatment.

Women: Before starting treatment with leuprorelin acetate, pregnancy must be excluded (see section 4.3) and undiagnosed abnormal vaginal bleeding must be investigated, diagnosis confirmed and relevant management initiated. During treatment with leuprorelin acetate, patients should be instructed to prevent conception e.g. with the use of non-hormonal methods. Since menstruation should stop with effective doses of PROSTAP 3, the patient should notify her physician if regular menstruation persists.

Children with central precocious puberty: Before starting treatment with leuprorelin acetate, a precise diagnosis of idiopathic and/or neurogenic central precocious should be made and in girls, pregnancy must be excluded (see section 4.3).

The therapy is a long-term treatment, adjusted individually. PROSTAP 3 should be administered as precisely as possible in regular 3-monthly periods. An exceptional delay of the injection date for a few days (90 ± 2 days) does not influence the results of the therapy.

In the event of a sterile abscess at the injection site (mostly reported after i.m. injection of higher than the recommended dosage) the absorption of leuprorelin acetate from the depot can be decreased. In this case the hormonal parameters (testosterone, oestradiol) should be monitored at 2-week intervals (see 4.2).

The treatment of children with progressive brain tumours should follow a careful individual appraisal of the risks and benefits.

The occurrence of vaginal bleeding, spotting and discharge after the first injection may occur as a sign of hormone withdrawal in girls. Vaginal bleeding beyond the first/second month of treatment needs to be investigated.

Bone mineral density (BMD) may decrease during GnRH therapy for central precocious puberty. However, after cessation of treatment subsequent bone mass accrual is preserved, and peak bone mass in late adolescence does not seem to be affected by treatment.

Slipped femoral epiphysis can be seen after withdrawal of GnRH treatment. The suggested theory is that the low concentrations of estrogen during treatment with GnRH agonists weakens the epiphysial plate. The increase in growth velocity after stopping the treatment subsequently results in a reduction of the shearing force needed for displacement of the epiphysis.

4.5. Interaction with other medicinal products and other forms of interaction

No interaction studies have been performed.

Women and girls: No known interactions.

Men: Since androgen deprivation treatment may prolong the QT interval, the concomitant use of PROSTAP 3 with medicinal products known to prolong the QT interval or associated with Torsade de pointes such as class IA (e.g. quinidine, disopyramide) or class III (e.g. amiodarone, sotalol, dofetilide, ibutilide) antiarrhythmic medicinal products, methadone, moxifloxacin, antipsychotics, etc. should be carefully evaluated (see section 4.4).

4.6. Fertility, pregnancy and lactation

Safe use of leuprorelin acetate in pregnancy has not been established clinically.

Studies in animals have shown reproductive toxicity (see section 5.3). Before starting treatment with PROSTAP 3, pregnancy must be excluded. There have been reports of foetal malformation when PROSTAP 3 has been given during pregnancy.

PROSTAP 3 must not be used in women who are pregnant or breastfeeding (see section 4.3).

When used 3-monthly at the recommended dose, PROSTAP 3 usually inhibits ovulation and stops menstruation. Contraception is not ensured, however, by taking PROSTAP 3 and therefore patients should use non-hormonal methods of contraception during treatment and after cessation of treatment until the return of menses.

Patients should be advised that if they miss successive doses of PROSTAP 3, breakthrough bleeding or ovulation may occur with the potential for conception. Patients should be advised to see their physician if they believe they may be pregnant. If a patient becomes pregnant during treatment, the drug must be discontinued. The patient must be apprised of this evidence and the potential for an unknown risk to the foetus.

In girls with central precocious puberty: See section 4.3 Contraindications.

4.7. Effects on ability to drive and use machines

PROSTAP 3 can influence the ability to drive and use machines due to visual disturbances and dizziness.

4.8. Undesirable effects

Adverse reactions seen with PROSTAP 3 are due mainly to the specific pharmacological action, namely increases and decreases in certain hormone levels.

The following tables list adverse reactions with leuprorelin based on experience from clinical trials as well as from post-marketing experience. Adverse reactions are grouped by MedDRA System Organ Classes and frequency classification. Frequencies are defined as: very common (≥1/10); common (≥1/100 to <1/10); uncommon (≥1/1,000 to <1/100); rare (≥1/10,000 to <1/1,000); very rare (<1/10,000); not known (cannot be estimated from the available data).

Men: In cases where a "tumour flare" occurs after PROSTAP 3 therapy, an exacerbation may occur in any symptoms or signs due to disease. Adverse events, which may occur particularly at the beginning of treatment include urinary tract obstruction (as urinary symptoms). In patients with spinal cord compression, bone pain, weakness of the lower extremities and paraesthesia (as neurologic symptom) may also occur (see section 4.4). These symptoms subside on continuation of therapy.

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. Website: www.mhra.gov.uk/yellowcard or search for MHRA Yellow Card in the Google Play or Apple App Store.
