7. Product details

1. Why am I using LUVERIS?

LUVERIS contains the active ingredient lutropin alfa (rch), a recombinant luteinising hormone (LH). This hormone is essentially similar to the hormone found naturally in human, but it is made by means of biotechnology. LUVERIS belongs to the family of hormones called gonadotrophins, which are involved in the normal control of reproduction.

LUVERIS is used for the stimulation of follicular development in women with severe LH and FSH deficiency.

2. What should I know before I use LUVERIS?

Warnings

Do not use LUVERIS if:

  • you are allergic to lutropin alfa (rch), or any of the ingredients listed at the end of this leaflet.
    Always check the ingredients to make sure you can use this medicine.
  • you are pregnant or breastfeeding
  • you have an unexplained ovarian cyst or ovarian enlargement
  • you have unexplained vaginal or uterine bleeding
  • you have cancer of the ovaries, uterus or breasts
  • you have tumours of the pituitary gland or hypothalamus

Check with your doctor if you:

  • take any medicines for any other condition
  • have or have had any other medical conditions, such as:
    - kidney disease
    - liver disease
    - you or your family have increased risk factors for developing blood clots, e.g. stroke, heart attacks
    - porphyria or a family history of porphyria

During treatment, you may be at risk of developing certain side effects. It is important you understand these risks and how to monitor for them. See additional information under Section 6. Are there any side effects?

Pregnancy and breastfeeding

Check with your doctor if you are pregnant while using LUVERIS.

Talk to your doctor if you are breastfeeding or intend to breastfeed.

Compared to natural conception, the frequency of multiple pregnancies and births is increased in patients receiving this treatment. Your doctor will monitor your ovarian response to minimise the chance of multiple pregnancies.

There may be a slightly increased risk of birth defects in women using assisted reproductive technologies. This may be due to increased maternal age, genetic factors, multiple pregnancies or the procedures.

Talk to your doctor about any concerns you may have before undergoing treatment with LUVERIS.

3. What if I am taking other medicines?

Tell your doctor or pharmacist if you are taking any other medicines, including any medicines, vitamins or supplements that you buy without a prescription from your pharmacy, supermarket or health food shop.

Check with your doctor or pharmacist if you are not sure about what medicines, vitamins or supplements you are taking and if these affect LUVERIS.

4. How do I use LUVERIS?

How much to use

  • It is recommended that your treatment with LUVERIS starts with 75 IU daily, together with 75 IU to 150 IU of follitropin alfa.
  • Your treatment should be tailored according to your individual response. Your doctor will tell you how much LUVERIS to use.

When to use LUVERIS

  • Your doctor will tell you when to take LUVERIS.
  • LUVERIS is given as a course of daily injections. You should have your injection at the same time each day.

How to use LUVERIS

  • LUVERIS should be injected daily under the skin (subcutaneous) in the lower abdominal area or thigh.
  • Each vial is for single use only.
  • The injection site should be changed daily to lessen possible injection site reactions.
  • Before using LUVERIS, your doctor or nurse can teach you the injection technique.
  • Read the Instructions for Use carefully, as follows:
  1. Wash your hands

It is important that your hands and the items you use be as clean as possible.

  1. Assemble everything you need

Please note that alcohol swabs, syringes and needles are not provided in the package. Find a clean area and lay out everything:

  • Two alcohol swabs
  • One solvent vial
  • One vial containing LUVERIS
  • One syringe
  • One big needle for reconstitution
  • A fine-bore needle for subcutaneous injection
  1. Draw up the solvent

Remove the protective cap from the solvent vial. Attach the needle for reconstitution (the bigger needle) to the syringe and draw up some air into the syringe by pulling the plunger to approximately the 1 mL mark. Then insert the needle into the vial, push the plunger to expel the air, turn the vial upside down and gently draw up all the solvent.

  1. Prepare the injection solution

Remove the protective cap from LUVERIS powder vial, slowly inject the solvent in the syringe into the vial of LUVERIS.

Swirl gently without removing the syringe. Do not shake.

The powder will dissolve into a clear solution immediately. Do not use the solution if it is not clear.

Turn the vial upside down, gently draw the solution back into the syringe

  1. Injection

Change the needle for the fine-bore needle and remove any air bubbles: If you see air bubbles in the syringe, hold the syringe with the needle pointing upwards and gently flick the syringe until all the air collects at the top.

Gently push the plunger until the air bubbles are gone.

Immediately inject the solution. Your doctor or nurse will tell you where to inject (e.g. tummy, front of thigh).

Wipe the chosen area with an alcohol swab. Firmly pinch the skin together and insert the needle at a 45° to 90° angle using a dart-like motion. Inject under the skin, as you were taught. Do not inject directly into a vein.

Inject the solution by pushing gently on the plunger. Take as much time as you need to inject all the solution.

Immediately withdraw the needle and clean the skin with an alcohol swab or cotton pad.

  1. Dispose of all used items

Once you have finished your injection, immediately discard all needles and empty glass containers in a sharps container. Any unused solution must be discarded.

If you forget to use LUVERIS

LUVERIS should be used regularly at the same time each day. If you miss your dose at the usual time, contact your doctor or nurse immediately for advice.

If you use too much LUVERIS

If you think that you have used too much LUVERIS, you may need urgent medical attention.

You should immediately:

  • phone the Poisons Information Centre
    (by calling 13 11 26), or
  • contact your doctor, or
  • go to the Emergency Department at your nearest hospital.

You should do this even if there are no signs of discomfort or poisoning.

5. What should I know while using LUVERIS?

Things you should do

See your doctor regularly. Your doctor will monitor you closely throughout your treatment.

Tell your doctor immediately if you become pregnant while using LUVERIS.

If you plan to have surgery, tell your doctor or dentist that you are using LUVERIS.

Remind any doctor, dentist or pharmacist you visit that you are using LUVERIS.

Things you should not do

  • Do not stop using this medicine suddenly without telling your doctor.
  • Do not change the dose unless your doctor tells you to.
  • Do not give this medicine to anyone else even if they have the same condition as you.

Ovarian Hyperstimulation Syndrome (OHSS)

Treatment with LUVERIS may increase your risk of developing a condition called ovarian hyperstimulation syndrome (OHSS). This is when the ovaries overact to the hormonal treatment and become larger.

The most common symptom is lower abdominal pain. Your doctor will monitor your treatment using ultrasound and blood tests to help determine if you are likely to develop OHSS. If necessary, your doctor will delay or cancel your LUVERIS injection. You may also be advised to refrain from sexual intercourse or use barrier methods until the end of the cycle if this occurs.

Driving or using machines

Be careful before you drive or use any machines or tools until you know how LUVERIS affects you.

Looking after your medicine

  • Prior to reconstitution keep the vials in a dry cool place where the temperature is below 25°C.
  • Store in the original package in order to protect from light.
  • Once the LUVERIS powder is dissolved with the solvent provided, it should be injected immediately. This is due to the solvent not containing any preservative. Any solution that is left over must be discarded.
  • Do not use the dissolved solution if it contains particles or is not clear.

Follow the instructions in the carton on how to take care of your medicine properly.

Store it in a cool dry place away from moisture, heat or sunlight; for example, do not store it:

  • in the bathroom or near a sink, or
  • in the car or on window sills.

Keep it where young children cannot reach it.

Getting rid of any unwanted medicine

If you no longer need to use this medicine or it is out of date, take it to any pharmacy for safe disposal.

Do not use this medicine after the expiry date.

6. Are there any side effects?

BRAND INFORMATION

Brand name

Luveris

Active ingredient

Lutropin alfa

Schedule

S4

 

1 Name of Medicine

Lutropin alfa (rch).

2 Qualitative and Quantitative Composition

Lutropin alfa is a recombinant human luteinising hormone (r-hLH) derived from a Chinese Hamster Ovary cell line that has been modified by the addition of human genes encoding the LH α- and β-chains.
Each vial of Luveris contains 75 IU of lutropin alfa as lyophilised powder.
For the full list of excipients, see Section 6.1 List of Excipients.

3 Pharmaceutical Form

Powder for injection in vial(s).
Luveris is available as a sterile, lyophilised powder.
It is intended for co-administration with follitropin alfa as subcutaneous injection after reconstitution with sterile water for injections.

4 Clinical Particulars

4.1 Therapeutic Indications

Luveris in association with a recombinant follicle stimulating hormone (FSH) preparation is indicated for the stimulation of follicular development in women with severe LH and FSH deficiency.

4.2 Dose and Method of Administration

Treatment with Luveris should be initiated under the supervision of a physician experienced in the treatment of fertility problems. Self-administration of Luveris should only be performed by patients who are well-motivated, adequately trained and with access to expert advice.
In LH and FSH deficient women, the objective of Luveris therapy, in association with FSH is to promote follicular development followed by final maturation after the administration of human chorionic gonadotrophin (hCG). Luveris should be given as a course of daily injections concomitantly with FSH. If the patient is amenorrhoeic and has low endogenous oestrogen secretion, treatment can commence at any time. Nevertheless, the possibility of pregnancy should be first excluded by clinical or other means.
All clinical experience to date with Luveris in this indication has been gained with concomitant daily administration of follitropin alfa.
Luveris is intended for daily subcutaneous administration. The powder should be reconstituted, immediately prior to use, with the solvent provided.
The majority of the women with very low LH levels (< 1.2 IU/L as used in clinical studies, but this may vary from laboratory to laboratory) will have a poor ovarian response to r-hFSH alone. However, some women may have adequate follicular response. Clinicians will need to decide on a case by case basis whether to commence ovulation induction with r-hFSH alone or in combination with Luveris.
The efficacy studies have suggested that the minimum effective dose of Luveris is 37.5 IU. However, dose titration is recommended according to individual patient response.
A recommended regimen commences at 75 IU of Luveris daily with 75-150 IU FSH. Treatment should be tailored to the individual patient's response as assessed by measuring: (i) follicle size by ultrasound and (ii) oestrogen response.
Clinical studies have employed doses of up to 225 IU of lutropin alfa and 150 IU follitropin alfa per day to induce follicular development. If a patient fails to respond after 3 weeks of treatment, the cycle should be abandoned and the patient should recommence treatment with a higher starting dose of follitropin alfa and/or Luveris than in the abandoned cycle.
If there is insufficient follicular growth, it is reasonable to increase the FSH dose, but if there is good follicular development with a low oestradiol level, this suggests that more LH may be required.
In clinical trials, Luveris has been associated with higher oestradiol levels than follitropin alfa alone. If an FSH dose increase is deemed appropriate, dose adaptation should preferably be at 7 to 14 day intervals and preferably with 37.5 to 75 IU increments.
When an optimal response is obtained, a single injection of 250 microgram of recombinant hCG (r-hCG) or 5,000 IU to 10,000 IU hCG should be administered 24 to 48 hours after the last Luveris and FSH injections. The patient is recommended to have coitus on the day of, and on the day following, hCG administration. Alternatively, intrauterine insemination (IUI) or another medically assisted reproduction procedure may be performed based on the physician's judgement of the clinical case.
Luteal phase support should be considered since lack of endogenous gonadotrophins after ovulation may lead to premature failure of the corpus luteum.
If an excessive response is obtained, treatment should be stopped and hCG withheld. Treatment should recommence in the next cycle at an FSH dosage lower than that of the previous cycle.
Product is for single use in one patient only. Discard any residue.

4.3 Contraindications

Luveris is contraindicated in patients with:
hypersensitivity to gonadotrophins or to any of the excipients;
ovarian, uterine or mammary carcinoma;
active, untreated tumours of the hypothalamus or pituitary gland;
ovarian enlargement or cyst of unknown aetiology;
gynaecological haemorrhages of unknown origin;
pregnancy and lactation.

4.4 Special Warnings and Precautions for Use

Before starting treatment, the couple's infertility should be assessed as appropriate and putative contraindications for pregnancy evaluated. It is recommended that Luveris is not used in conditions where an effective response is usually not expected, such as primary ovarian failure, malformation of the sexual organs or fibroid tumours of the uterus that are incompatible with pregnancy. In addition, patients should be evaluated for hypothyroidism, adrenocortical deficiency and hyperprolactinemia, and appropriate specific treatment given.

Ovarian hyperstimulation syndrome (OHSS).

A certain degree of ovarian enlargement is an expected effect of controlled ovarian stimulation. It is more commonly seen in women with polycystic ovarian syndrome and usually regresses without treatment.
Distinct from uncomplicated ovarian enlargement, OHSS is a condition that can manifest itself with increasing degrees of severity. It comprises marked ovarian enlargement, high serum sex steroids, and an increase in vascular permeability which can result in an accumulation of fluid in the peritoneal, pleural and, rarely, in the pericardial cavities.
Mild to moderate OHSS is a common adverse effect of ovulation induction with gonadotrophins; the risk should be considered and discussed with women prior to treatment.
Independent risk factors for developing OHSS include young age, lean body mass, polycystic ovarian syndrome, higher doses of exogenous gonadotrophins, high absolute or rapidly rising serum oestradiol levels and previous episodes of OHSS, large number of developing ovarian follicles and large number of oocytes retrieved in Assisted Reproductive Technology (ART) cycles.
Adherence to recommended Luveris and FSH dosage and regimen of administration can minimise the risk of ovarian hyperstimulation. Monitoring of stimulation cycles by ultrasound scans, as well as oestradiol measurements, is recommended to identify risk factors early.
There is evidence to suggest that hCG plays a key role in triggering OHSS and that the syndrome may be more severe and more protracted if pregnancy occurs. Therefore, if monitoring results indicate a high risk of OHSS or if signs of OHSS occur, it is recommended that hCG be withheld and the patient be advised to refrain from coitus or use barrier methods of contraception for at least 4 days. As OHSS may progress rapidly (within 24 hours) or over several days to become a serious medical event, patients should be followed for at least two weeks after hCG administration.
Mild manifestations of OHSS may include abdominal pain, abdominal discomfort and distension, or enlarged ovaries. Moderate OHSS may additionally present with nausea, vomiting, ultrasound evidence of ascites or marked ovarian enlargement. Severe OHSS further includes symptoms such as severe ovarian enlargement, weight gain, dyspnoea or oliguria. Clinical evaluation may reveal signs such as hypovolaemia, haemoconcentration, electrolyte imbalances, ascites, pleural effusions, or acute pulmonary distress. Very rarely, severe OHSS may be complicated by ovarian torsion or thromboembolic events, such as pulmonary embolism, ischaemic stroke or myocardial infarction.
Mild or moderate OHSS usually resolves spontaneously. If severe OHSS occurs, it is recommended that gonadotrophin treatment be stopped, the patient be hospitalised and appropriate therapy be started.

Multiple pregnancy.

In patients undergoing induction of ovulation, the incidence of multiple pregnancy is increased compared with natural conception. The majority of multiple conceptions are twins. Multiple pregnancies, especially higher order, carry an increased risk of adverse maternal and perinatal outcomes. The patient should be advised of the potential risk of multiple births before starting treatment.
To minimise the risk of twins or higher order multiple pregnancy, careful monitoring of ovarian response is recommended. Appropriate management, such as cycle cancellation, should be considered in line with current clinical practice.
In patients undergoing ART procedures, the risk of multiple pregnancy is related mainly to the number of embryos replaced, their quality and the patient's age. Single embryo transfer in good prognosis cycles substantially reduces the risk of multiple pregnancy with little effect on live birth rates.

Pregnancy loss.

The incidence of pregnancy loss by miscarriage or abortion is higher in patients undergoing stimulation of follicular growth for ovulation induction than following natural conception.

Thromboembolic events.

In women with recent or ongoing thromboembolic disease or women with generally recognised risk factors for thromboembolic events, such as personal or family history, treatment with gonadotrophins may further increase the risk for aggravation or occurrence of such events. In these women, the benefits of gonadotrophin administration need to be weighed against the risks. It should be noted however, that pregnancy itself as well as OHSS also carry an increased risk of thromboembolic events.

Porphyria.

In patients with porphyria or a family history of porphyria, gonadotrophins may increase the risk of an acute attack. Deterioration or a first appearance of this condition may require cessation of treatment.

Congenital anomalies.

The prevalence of congenital anomalies after the use of ART may be slightly higher than after spontaneous conceptions. Possible contributing factors include aspects inherent in the couple's infertility, ovulation induction agents, other medicines used in treatment and the ART procedures. While there is no specific evidence from clinical trials or post-marketing data implicating gonadotrophin use in adverse effects on pregnancy, embryonal or foetal development, parturition or postnatal development, ovulation induction agents cannot be excluded as a contributing factor.

Use in hepatic or renal impairment.

Caution should be used and close monitoring considered when administering Luveris to patients with renal or hepatic impairment. There are currently no data available on the use of Luveris in patients with hepatic or renal impairment.

Use in the elderly.

No data available.

Paediatric use.

No data available.

Effects on laboratory tests.

No data available.

4.5 Interactions with Other Medicines and Other Forms of Interactions

Luveris should not be administered as a mixture with other medicines in the same injection, except follitropin alfa, for which studies have shown that co-administration does not significantly alter the activity, stability, pharmacokinetic nor pharmacodynamic properties of the active substances.

4.6 Fertility, Pregnancy and Lactation

Effects on fertility.

See Section 4.1 Therapeutic Indications.
(Category B3)
Luveris should not be administered during pregnancy as it may cause foetal harm when given to a pregnant woman (see Section 4.3 Contraindications). Data on a limited number of human pregnancies exposed inadvertently following controlled ovarian stimulation indicate no adverse reactions of gonadotrophins on pregnancy, embryonal or foetal development, parturition or postnatal development. In the case of inadvertent administration during pregnancy, clinical data are not sufficient to exclude a teratogenic effect of Luveris.
Treatment of pregnant rats and rabbits with Luveris at doses of 10 IU/kg/day SC and above was associated with embryonic resorptions (approximately 0.4x and 0.8x clinical exposure at the maximum recommended clinical dose of 225 IU/day, based on body surface area, respectively). Teratogenicity was not observed in pregnant rats and rabbits dosed with Luveris at doses up to 20 IU/kg/day SC (approximately 0.8x and 1.6x clinical exposure, based on body surface area, respectively). Administration of 10 IU/kg/day Luveris to rats from late gestation to weaning resulted in adverse effects on the post-natal survival and growth of offspring.
Luveris should not be administered during lactation (see Section 4.3 Contraindications). Secretion of r-hLH and/or its degradation products has been shown to occur in lactating rats.

4.7 Effects on Ability to Drive and Use Machines

No studies on the effects on the ability to drive and use machines have been performed.

4.8 Adverse Effects (Undesirable Effects)

Luveris is used for the stimulation of follicular development in association with follitropin alfa. In this context, undesirable effects may be due to either or both of the substances used, or to their pharmacodynamic consequences.
There is considerable post-marketing safety experience with human luteinising hormone (hLH) containing products of urinary origin. The safety profile of Luveris is expected to be very similar to that of urine derived hLH, with the exception of hypersensitivity reactions and application site disorders.
In clinical trials, a maximal score of all mild and moderate injection site reactions (bruising, pain, redness, itching or swelling) was reported in 12.7% (mild) and 2.7% (moderate) of the 2282 injections in 271 treatment cycles, respectively. Among the 170 patients treated, only 2 patients (1.2%) reported a severe injection site reaction.
OHSS was observed in 3.9% of treatment cycles with Luveris. Six serious OHSS reports (2.3%) occurred in 259 treatment cycles.
Ovarian cysts and enlargement are common. Complications including adnexal torsion and haemoperitoneum have been reported rarely with human menopausal gonadotrophin therapy.
Ectopic pregnancy may also occur, especially in women with a history of prior tubal disease.
The following definitions apply to the frequency terminology used hereafter: 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.

General disorders and administration site condition.

Common: injection site reactions (e.g. pain, erythema, haematoma, swelling and/or irritation at the site of injection).

Nervous system disorders.

Common: headache.

Gastrointestinal disorders.

Common: nausea, vomiting, diarrhoea, abdominal pain, abdominal discomfort.

Reproductive system and breast disorders.

Common: mild or moderate OHSS (including associated symptomatology), ovarian cyst, breast pain, pelvic pain.

Vascular disorders.

Very rare: thromboembolism, usually associated with severe OHSS.

Immune system disorders.

Very rare: mild to severe hypersensitivity reactions including anaphylactic reactions and shock.
The reported undesirable effects are in agreement with those reported for other hLH containing products.

Reporting suspected adverse effects.

Reporting suspected adverse reactions after registration 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 at www.tga.gov.au/reporting-problems in Australia, or at https://nzphvc.otago.ac.nz/reporting/ in New Zealand.

4.9 Overdose

The effects of overdosage of Luveris are unknown; nevertheless, there is a possibility that OHSS may occur which is further described in Section 4.4 Special Warnings and Precautions for Use.
Single doses of up to 40,000 IU of Luveris have been administered to healthy female volunteers without serious adverse events and were well tolerated.
For information on the management of overdose, contact the Poisons Information Centre on 13 11 26 (Australia) or 0800 764 766 (New Zealand).

5 Pharmacological Properties

5.1 Pharmacodynamic Properties

Mechanism of action.

Luteinising hormone binds on the ovarian theca (and granulosa) cells and testicular Leydig cells to a receptor shared with human chorionic gonadotrophin hormone (hCG). This LH/hCG transmembrane receptor is a member of the super-family of G protein-coupled receptors and it has a large extracellular domain. The in vitro binding affinities of r-hLH, pituitary hLH and hCG to the LH/hCG receptor on murine Leydig tumour cells are of similar orders of magnitude.
Luteinising hormone (LH) and follicle stimulating hormone (FSH) are secreted from the anterior pituitary gland in response to gonadotropin-releasing hormone (GnRH) and play a complementary role in follicle development and ovulation. In theca cells, LH stimulates the secretion of androgens that are transferred to granulosa cells to be converted to oestradiol (E2) by aromatase. In granulosa cells, FSH stimulates the development of ovarian follicles, while LH action is involved in follicle development, maturation and steroidogenesis.
In the stimulation of follicular development in anovulatory women deficient in LH and FSH, the primary effect resulting from administration of Luveris is an increase in oestradiol secretion by the follicles, the growth of which is stimulated by r-FSH.

Clinical trials.

The safety and efficacy of Luveris have been examined in five studies for induction of ovulation in women with hypogonadotropic hypogonadism (HH).
Pivotal studies. The safety and efficacy of Luveris administered subcutaneously and concomitantly with recombinant human FSH (r-hFSH) for ovulation induction in women with HH was assessed and confirmed in the following 2 international pivotal studies.
In clinical trials (studies 6253 and 21008), patients were defined by an endogenous serum LH level < 1.2 IU/L as measured in a central laboratory. However, it should be taken into account that there are variations between LH measurements performed in different laboratories.

Study 6253.

Study 6253 was a Phase II randomized, open-label, dose-finding study to determine the minimal effective dose and assess the safety of Luveris to support r-hFSH-induced follicular development in LH and FSH deficient anovulatory women. Patients were randomized to treatment with 0, 25, 75 or 225 IU Luveris concomitant with 150 IU of r-hFSH for up to 3 treatment cycles. Thirty-eight patients were enrolled and treated in a total of 53 treatment cycles.
The proportion of patients who fulfilled the primary efficacy endpoint criteria (at least one follicle ≥ 17 mm; E2 ≥ 400 picomol/L; mid-luteal phase P4 ≥ 25 nanomol/L) was related to the dose of Luveris, both when excessive follicular development was not included as a success (0.0%, 14.3%, 44.4% and 50.0% for treatment with 0, 25, 75 and 225 IU Luveris, respectively; p=0.0124) and when excessive follicular development was included as a success (0.0%, 14.3%, 66.7% and 80.0% for treatment with 0, 25, 75 and 225 IU Luveris, respectively; p=0.0001).

Study 21008.

The safety and efficacy of Luveris 75 IU administered subcutaneously for induction of ovulation in women with HH and severe gonadotrophin deficiency was assessed in this Phase III double-blind, placebo-controlled, randomized trial of 39 women.
The primary efficacy parameter in this single-cycle study was follicular development as defined by: (i) at least one follicle with a mean diameter of ≥ 17 mm, (ii) pre-ovulatory serum E2 level ≥ 109 picogram/mL (400 picomol/L) and (iii) mid-luteal phase P4 level ≥ 7.9 nanogram/mL (25 nanomol/L). Patients with excessive follicular development or who became pregnant were considered treatment successes from the perspective of the analysis.
The efficacy results for Study 21008 are summarized in Table 1.
The efficacy results for the same study are also assessed when risk of OHSS is considered as an efficacy failure in Table 2.
In studies 6253 and 21008, achievement of an adequate follicular development as the optimal well established and surrogate marker of conception was consistently found in 66.7% of patients with LH < 1.2 IU treated with FSH and 75 IU Luveris. This result was based on studies 6253 [66.7%] and 21008 [66.7%] and was calculated when risk of ovarian hyperstimulation syndrome (OHSS) and pregnancy outcome were considered as treatment successes. When risk of OHSS was considered as a treatment failure, adequate follicular development was found in 43.2% of patients (combined analysis of follicular development in studies 6253 and 21008).
Other studies. The safety and efficacy of Luveris administered subcutaneously concomitantly with r-hFSH for ovulation induction in women with HH was also investigated in 3 additional studies.
Study 6905 was a Phase II/III open-label, randomized, multicenter study to determine the minimal effective dose and assess the safety of Luveris administered with r-hFSH to induce follicular development in anovulatory women with HH and moderate gonadotrophin deficiency. Forty patients were enrolled and treated.
Study 7798 was a Phase III multicenter study to assess the efficacy and safety of Luveris administered with r-hFSH for induction of follicular development in LH and FSH deficient anovulatory women and enrolled 15 patients.
Study 8297 was a Phase III multicenter, non-comparative study to assess the efficacy and safety of Luveris administered with r-hFSH for induction of follicular development in LH and FSH-deficient anovulatory women and enrolled 38 patients.
Among the 170 patients with HH enrolled in the 5 Luveris development studies, 154 were seeking fertility and of these 127 were treated with Luveris. Overall 41 of 127 (32%) Luveris treated patients (all doses) and 31 of 100 (31%) in the Luveris 75 IU dose group achieved a pregnancy over a total of 205 treatment cycles (see Table 3).
No direct comparison of r-hLH and r-hFSH versus human menopausal gonadotrophin (hMG) has been performed. Comparison with historical data suggests that the ovulation rate with the combination is similar to what can be obtained with hMG.

5.2 Pharmacokinetic Properties

The pharmacokinetics of lutropin alfa have been studied in pituitary desensitised female volunteers from 75 IU up to 40,000 IU.
The pharmacokinetic profile of lutropin alfa is similar to that of urinary-derived hLH. Following intravenous administration, lutropin alfa is rapidly distributed with an initial half-life of approximately one hour and eliminated from the body with a terminal half-life of about 10-12 hours. The steady state volume of distribution is around 10-14 L. Lutropin alfa shows linear pharmacokinetics, as assessed by AUC, which is directly proportional to the dose administered. Total clearance is around 2 L/h, and less than 5% of the dose is excreted in the urine. The mean residence time is approximately 5 hours.
Following subcutaneous administration, the absolute bioavailability is approximately 60%; the terminal half-life is slightly prolonged. The lutropin alfa pharmacokinetics following single and repeated administration of Luveris are comparable and the accumulation ratio of lutropin alfa minimal. There is no pharmacokinetic interaction with follitropin alfa when administered simultaneously.

5.3 Preclinical Safety Data

Genotoxicity.

Lutropin alfa was inactive in in vitro tests for gene mutation and chromosomal damage, and in an in vivo mouse micronucleus test.

Carcinogenicity.

Long-term carcinogenicity studies have not been carried out.

6.7 Physicochemical Properties

Chemical structure.

Lutropin alfa is a recombinant human luteinising hormone (r-hLH). r-hLH is a human gonadotrophin hormone, composed of two non-covalently linked, non-identical protein components designated as the α- and β-subunits. It is a glycoprotein hormone with molecular weight (MW) of about 29,000 Da. The α-subunit is common to all four members of the gonadotropin hormone family. The α-subunit is formed by 92 amino acids and possesses two sites of N-linked glycosylation (Asn 52 and Asn 78). Five disulphide bonds contribute to its tertiary structure. The β-subunit, which is hormone specific, is 121 amino acids in length and possesses a single site of N-linked glycosylation (Asn 30). It contains six disulphide bridges.
The physicochemical, immunological and biological activities of r-hLH are comparable to those of human menopausal urinary-hLH (u-hLH). The main difference between u-hLH and r-hLH is that the u-hLH carbohydrate moieties are essentially capped with sulphate groups, while in r-hLH it is with sialic acid. Preclinical and clinical experience, however, indicate that this has no significant impact on the pharmacokinetic characteristics of these molecules.
