Cream.

White to off white cream

Treatment of facial hirsutism in female adolescents (aged 12 to 18 years) and adult women.

Posology

Vaniqa cream should be applied to the affected area twice daily, at least eight hours apart. Efficacy has only been demonstrated for affected areas of the face and under the chin. Application should be limited to these areas. Maximal applied doses used safely in clinical trials were up to 30 grams per month.

Improvement in the condition may be noticed within eight weeks of starting treatment.

Continued treatment may result in further improvement and is necessary to maintain beneficial effects. The condition may return to pre-treatment levels within eight weeks following discontinuation of treatment.

Use should be discontinued if no beneficial effects are noticed within four months of commencing therapy.

Patients may need to continue to use a hair removal method (e.g. shaving or plucking) in conjunction with Vaniqa. In that case, the cream should be applied no sooner than five minutes after shaving or use of other hair removal methods, as increased stinging or burning may otherwise occur.

Special population

Elderly: (> 65 years) no dosage adjustment is necessary.

Paediatric population: The safety and efficacy of Vaniqa in children aged 0 to 12 years have not been established. No data are available.

For adolescents aged 12 to 18 years, the posology is the same as in adults.

Hepatic/renal impairment: the safety and efficacy of Vaniqa in women with hepatic or renal impairment have not been established. As the safety of Vaniqa has not been studied in patients with severe renal impairment, caution should be used when prescribing Vaniqa for these patients. No data are available.

Method of administration

A thin layer of the cream should be applied to clean and dry affected areas. The cream should be rubbed in thoroughly. The medicinal product should be applied such that no visual residual product remains on the treated areas after rub-in. Hands should be washed after applying this medicinal product. For maximal efficacy, the treated area should not be cleansed within four hours of application. Cosmetics (including sunscreens) can be applied over the treated areas, but no sooner than five minutes after application.

Hypersensitivity to eflornithine or to any of the excipients (see section 6.1).

Excessive hair growth can result from serious underlying disorders (e.g. polycystic ovary syndrome, androgen secreting neoplasm) or certain active substances (e.g. cyclosporin, glucocorticoids, minoxidil, phenobarbitone, phenytoin, combined oestrogen-androgen hormone replacement therapy). These factors should be considered in the overall medical treatment of patients who might be prescribed Vaniqa.

Vaniqa is for cutaneous use only. Contact with eyes or mucous membranes (e.g. nose or mouth) should be avoided. Transient stinging or burning may occur when the cream is applied to abraded or broken skin.

If skin irritation or intolerance develops, the frequency of application should be reduced temporarily to once a day. If irritation continues, treatment should be discontinued and the physician consulted.

This medicinal product contains cetostearyl alcohol and stearyl alcohol which may cause local skin reactions (e.g. contact dermatitis) as well as methyl parahydroxybenzoate and propyl parahydroxybenzoate which may cause allergic reactions (possibly delayed).

No interaction studies have been performed.

Pregnancy

Throughout clinical trials data from a limited number of exposed pregnancies (22) indicate that there is no clinical evidence that treatment with Vaniqa adversely affects mothers or foetuses. Among the 22 pregnancies that occurred during the trials, only 19 pregnancies occurred while the patient was using Vaniqa. Of these 19 pregnancies, there were 9 healthy infants, 5 elective abortions, 4 spontaneous abortions and 1 birth defect (Down's Syndrome to a 35 year old). To date, no other relevant epidemiological data are available. Animal studies have shown reproductive toxicity (see section 5.3). The potential risk to humans is unknown. Therefore, women who are pregnant or planning pregnancy should use an alternative means to manage facial hair.

Breastfeeding

It is not known if eflornithine is excreted in human milk. Women should not use Vaniqa whilst breastfeeding.

Fertility

There are no data available.

Vaniqa has no or negligible effects on the ability to drive and use machines.

The mostly skin related adverse reactions reported were primarily mild in intensity and resolved without discontinuation of Vaniqa or initiation of medical treatment. The most frequently reported adverse reaction was acne, which was generally mild. In the vehicle controlled trials (n= 596), acne was observed in 41% of patients at baseline; 7% of patients treated with Vaniqa and 8% treated with vehicle experienced a worsening of their condition. Of those with no acne at baseline, similar percentages (14%) reported acne following treatment with Vaniqa or vehicle.

The following listing notes the frequency of adverse skin reactions seen in clinical trials, according to MedDRA convention. MedDRA conventions for frequency are 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), or not known (cannot be estimated from the available data) including isolated reports. Note that over 1350 patients were treated with Vaniqa in these trials for 6 months to one year, while only slightly more than 200 patients were treated with vehicle for 6 months. Most events were reported at similar rates between Vaniqa and vehicle. The skin effects of burning, stinging, tingling, rash and erythema were reported at higher levels in Vaniqa treated patients compared to vehicle, as indicated by the asterisk (*).

Skin and subcutaneous tissue disorders

Paediatric population

The adverse reactions observed in adolescents are similar to the ones observed in adults.

Given the minimal cutaneous penetration of eflornithine (see section 5.2), overdose is highly unlikely. However, should very high dose cutaneous administration or accidental oral ingestion occur, attention should be paid to the effects seen with therapeutic doses of intravenous eflornithine (400 mg/kg/day or approximately 24 g/day) used in the treatment of Trypanosoma brucei gambiense infection (African sleeping sickness): hair loss, facial swelling, seizures, hearing impairment, gastrointestinal disturbance, loss of appetite, headache, weakness, dizziness, anaemia, thrombocytopenia and leucopenia.

If symptoms of overdose occur the use of the medicinal product should be stopped.

Pharmacotherapeutic group: other dermatological preparations, ATC code: D11AX16.

Eflornithine irreversibly inhibits ornithine decarboxylase, an enzyme involved in the production of the hair shaft by the hair follicle. Vaniqa has been shown to reduce the rate of hair growth.

The safety and efficacy of Vaniqa was eva luated in two double-blind, randomised, vehicle-controlled clinical trials involving 596 women of skin types I-VI (395 on Vaniqa, 201 on vehicle) treated for up to 24 weeks. Physicians assessed the change from baseline on a 4-point scale, 48 hours after women had shaved the treated areas of the affected areas of the face and under the chin, considering parameters such as hair length and density, and darkening of the skin associated with the presence of terminal hair. Improvement was seen as early as 8 weeks after initiation of treatment.

The combined results of these two trials are presented below:

* At end of therapy (Week 24). For patients who discontinued therapy during the trial last observations were carried forward to Week 24.

Statistically significant (p 0.001) improvement for Vaniqa versus vehicle was seen in each of these studies for women with marked improvement and clear/almost clear responses. These improvements resulted in a corresponding reduction in the darkening appearance of the facial skin associated with the presence of terminal hair. Subgroup analysis revealed a difference in treatment success where 27% of non-white women and 39% of white women showed a marked or better improvement. Subgroup analysis also showed that 29% of obese women (BMI 30) and 43% of normal weight women (BMI < 30) showed a marked or better improvement. About 12% of women in the clinical trials were postmenopausal. Significant improvement (p < 0.001) versus vehicle was seen in postmenopausal women.

Patient self-assessments demonstrated a significantly reduced psychological discomfort with the condition, as measured by responses to 6 questions on a visual analogue scale. Vaniqa significantly reduced how bothered patients felt by their facial hair and by the time spent removing, treating, or concealing facial hair. Patient comfort in various social and work settings was also improved. Patient self-assessments were found to correlate with physician observations of efficacy. These patient-observable differences were seen 8 weeks after initiating treatment.

The condition returned to pre-treatment levels within eight weeks after discontinuation of treatment.

Steady state cutaneous penetration of eflornithine in women from Vaniqa on facial skin of shaving women was 0.8%.

The steady state plasma half-life of eflornithine was approximately 8 hours. Steady state was reached within four days. The steady state peak and trough plasma concentrations of eflornithine were approximately 10 ng/ml and 5 ng/ml, respectively. The steady state 12-hour area under the plasma concentration versus time curve was 92.5 ng.hr/ml.

Eflornithine is not known to be metabolised and is eliminated primarily in the urine.

Non-clinical data reveal no special hazard for humans based on conventional studies of repeat dose toxicity, genotoxicity and carcinogenic potential, including one photocarcinogenicity study in mice.

In a dermal fertility study in rats, no adverse effects on fertility were observed at up to 180 times the human dose. In dermal teratology studies, no teratogenic effects were observed in rats and rabbits at doses up to 180 and 36 times the human dose, respectively. Higher doses resulted in maternal and foetal toxicity without evidence of teratogenicity.
