Method of administration

Before Finacea Gel is applied, the skin should be thoroughly cleaned with plain water and dried. A mild skin-cleansing agent may be used.

Occlusive dressing or wrappings should not be used, and hands should be washed after applying the gel.

In the event of skin irritation , the amount of gel per application should be reduced or the frequency of use of Finacea Gel should be reduced to once a day until the irritation ceases. If required, the treatment should be temporarily interrupted for a few days.

It is important to use Finacea Gel continuously over the entire period of treatment. The duration of use of Finacea Gel can vary from person to person and also depends on the severity of the skin disorder.

Acne: In general, a distinct improvement becomes apparent after 4 weeks. To obtain optimum results, Finacea Gel can be used over several months in accordance with the clinical outcome. In case of no improvement after 1 month or exacerbation of acne, Finacea Gel should be discontinued and other therapeutic options should be considered.

Rosacea: In general, a distinct improvement becomes apparent after 4 weeks of treatment. To obtain optimum results, Finacea Gel can be used over several months in accordance with the clinical outcome. In case of no improvement after 2 month or exacerbation of rosacea, Finacea Gel should be discontinued and other therapeutic options should be considered.

For external use only.

Finacea Gel contains benzoic acid which is mildly irritant to the skin, eyes and mucous membranes and propylene glycol which may cause skin irritation.). In the event of accidental contact, the eyes, mouth and/or affected mucous membranes should be washed with large amounts of water. If eye irritation persists, patients should consult a physician. The hands should be washed after each application of Finacea Gel.

It is advisable to avoid the concomitant use of alcoholic cleansers, tinctures and astringents, abrasives and peeling agents in patients using Finacea Gel for treatment of rosacea.

Worsening of asthma in patients treated with azelaic acid has been reported rarely during post-marketing surveillance.

No interaction studies have been performed. The composition of Finacea Gel gives no indication of any undesired interactions of the single components that could adversely affect the safety of the product. No drug-specific interactions were noted during any of the controlled clinical trials.

Pregnancy

There are no adequate and well-controlled studies of topically administered azelaic acid in pregnant women.

Animal studies do indicate the potential for effects with respect to pregnancy, embryo-fetal development, parturition or postnatal development.).

Caution should be exercised when prescribing azelaic acid to pregnant women.

Lactation

It is not known if azelaic acid is secreted into human milk in vivo. However an in vitro equilibrium dialysis experiment demonstrated that passage of drug into maternal milk may occur. But the distribution of azelaic acid into maternal milk is not expected to cause a significant change from baseline azelaic acid levels in the milk.

Azelaic acid is not concentrated in milk and less than 4% of topically applied azelaic acid is systemically absorbed, not increasing endogenous azelaic acid exposure above physiological levels. However, caution should be exercised when Finacea Gel is administered to a nursing woman.

Infants must not come into contact with treated skin/breast.

Fertility

There are no data on the effect of Finacea gel on human fertility.).

Finacea Gel has no influence on the ability to drive and use machines.

From clinical studies and post-marketing surveillance, the most frequently observed side effects included application site pruritus, application site burning and application site pain.

* for indication Rosacea

** for indication Acne

¹ These adverse reactions have been reported during post-approval use of Finacea gel.

Generally, local skin irritation regresses in the course of the treatment.

Pediatric population

Treatment of acne vulgaris in adolescents 12-18 years of age:

In 4 clinical phase II and II/III studies involving adolescents 12-17 years of age (120/383; 31%), the overall incidence of adverse events for Finacea Gel was similar for the groups aged 12-17 years (40%), aged >18 years (37%) and for the entire patient population (38%). This similarity also applied to the group aged 12-20 years (40%).

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.

Due to the very low local and systemic toxicity of azelaic acid intoxication is unlikely.

Pharmacotherapeutic group: Other anti-acne preparations for topical use, ATC code: D10A X03

Acne:

An antimicrobial action and a direct influence on follicular hyperkeratosis are assumed to be the basis for the therapeutic efficacy of azelaic acid in acne.

In vitro and in vivo, azelaic acid inhibits the proliferation of keratinocytes and normalizes the disturbed terminal epidermal differentiation processes in acne.

Clinically, a significant reduction of the colonization density of Propionibacterium acnes and a significant reduction in the fraction of free fatty acids in the skin surface lipids are observed.

In two double blind randomized clinical studies Finacea Gel was significantly superior to its vehicle in the median reduction of the sum of papules and pustules, and was 6 % less effective than benzoyl peroxide 5 % (p=0.056).

In these studies effectiveness of Finacea Gel on comedones has been evaluated as a secondary parameter. Finacea Gel was more effective than its vehicle in the median relative reduction of comedones, and was less effective in comparison to benzoyl peroxide 5 %.

Rosacea:

While the pathophysiology of rosacea is not completely understood, there is increasing consensus that inflammation involving the elevation of several pro- inflammatory effector molecules such as kallikrein-5 and cathelicidin as well as reactive oxygen species (ROS), is a central process of this disease.

Azelaic acid has been demonstrated to modulate the inflammatory response in normal human keratinocytes by: a) activating the peroxisome proliferator-activated receptor γ (PPARγ); b) inhibiting the trans-activation of nuclear factor-kB (NF-kB); c) inhibiting the production of pro-inflammatory cytokines and d) inhibiting the release of ROS from neutrophils, as well as direct scavenging effects on existing ROS.

In addition, azelaic acid has been shown to directly inhibit kallikrein-5 and cathelicidin expression in three models: in vitro (human keratinocytes), in murine skin and in the facial skin of patients with rosacea.

These anti-inflammatory properties of azelaic acid may play a role in the treatment of rosacea.

While the clinical significance of these findings regarding kallikrein-5 and cathelicidin and their impact on the pathophysiology of rosacea has not yet been fully demonstrated in a large clinical study, initial studies in human facial skin appear to confirm the in vitro and murine findings.

.

In the two vehicle controlled 12 week clinical studies in papulopustular rosacea, Finacea Gel was statistically significantly superior to its vehicle with regard to the reduction in inflammatory lesions, Investigator's Global Assessment, overall rating of improvement and with regard to improvement of erythema.

In the clinical study with the active comparator metronidazole 0.75 % gel in papulopustular rosacea, Finacea Gel showed significant superiority with regard to lesion count reduction (72.7 % versus 55.8 %), overall rating of improvement and with regard to improvement of erythema (56 % versus 42 %). The rate of cutaneous adverse events, which in most cases were mild to moderate, was 25.8 % with Finacea Gel and 7.1 % with metronidazole 0.75 % gel.

There was no noticeable effect on the teleangiectasias in the three clinical studies.

Azelaic acid penetrates into all layers of the skin after topical application of the gel. Penetration is faster into damaged skin than into intact skin. A total of 3.6 % of the dose applied was absorbed percutaneously after a single topical application of 1 g azelaic acid (administered as 5 g Skinoren 20 % Cream). Clinical investigations in acne patients indicated similar absorption rates of azelaic acid from Finacea Gel and Skinoren Cream.

A portion of the azelaic acid absorbed through the skin is excreted in unchanged form in the urine. The remaining portion is broken down by β-oxidation into dicarboxylic acids with shorter chain length (C₇, C₅), which have likewise been found in the urine.

Steady-state plasma levels of azelaic acid in rosacea patients after 8 weeks twice daily treatment with Finacea Gel were within the range also observed in volunteers and acne patients on normal diets. This indicates that the extent of percutaneous absorption of azelaic acid following twice daily application of Finacea Gel does not alter the systemic burden of azelaic acid derived from dietary and endogenous sources in a clinically meaningful way.

Non-clinical data reveal no special hazard for humans based on conventional studies of, repeated dose toxicity and toxicity to reproduction.

Embryofetal developmental studies with oral administration of azelaic acid to rats, rabbits, and cynomolgus monkeys during the period of organogenesis revealed embryotoxicity at doses where some maternal toxicity was noted.)

In a peri- and post-natal developmental study in rats where azelaic acid was administered orally from gestational day 15 to through day 21 postpartum slight disturbances in the post-natal development of fetuses were noted at oral doses that generated some maternal toxicity. The NOAEL was 3 times the MRHD based on BSA. No effects on sexual maturation of the fetuses were noted in this study

In vitro and in vivo studies with azelaic acid produced no evidence of mutagenic effects on germ and somatic cells. Conventional long-term carcinogenicity studies with oral administration of azelaic acid have not been performed. In a 26-week dermal carcinogenicity study using male and female transgenic (Tg.AC) mice, Finacea Gel and the gel vehicle did increase the number of papillomas in male animals after twice daily application at the treatment site. This effect was not observed after single administration in male and female mice. This effect may be associated with the vehicle application. The clinical relevance of the findings in animals to humans is not clear, especially in the light of the doubtful validity of the Tg.AC test system.

If azelaic acid came into contact with the eyes of monkeys and rabbits, signs of moderate to severe irritation became evident. Therefore, contact with the eyes should be avoided.

Azelaic acid administered once intravenously had no effects on the nervous system (Irwin test), cardiovascular function, intermediary metabolism, smooth muscles and liver and kidney function.
