Introduction
- Elidel is a steroid-free topical calcineurin inhibitor in cream at a concentration of 1%.
- It was recently introduced on the market (USA: 2002. Canada: 2003)
- Pimecrolimus selectively inhibits calcineurin phosphatase. This leads to a local decrease in the release of inflammatory cytokines and other proinflammatory mediators from T cells and mast cells.
- Safety and efficacy has been established in a number of clinical trials on atopic dermatitis (AD) and continuous safety monitoring is ongoing by an independent board
- There is no or minimal systemic absorption of topical Elidel
- Evidence shows that intermittent use, to be applied BID at the very first signs of eczema (itching, redness) can reduce the number / severity of eczema flares.
- Elidel rapidly reduces the pruritus (itch) associated with AD
Clinical Experience
- Extensive clinical experience exists with the use of Elidel cream in over 5 million patients with atopic dermatitis (including over 19,000 patients in clinical trials)
- Of the 19,000 patients in clinical trials, 14% were infants (3 to 23 months), 38% were children (2-17 years) and 48% were adults.
- Data indicate that the average patient treats for an average of 45 days over the course of a year and uses 72 g/ year
- Published trials have looked at the short term and intermittent long term use (up to 2 years) of Elidel in atopic dermatitis
Clinical trials
- Most clinical trials with Elidel have been done in patients with mild to moderate atopic dermatitis.
- Many trials with Elidel have a similar design. Elidel or placebo cream is applied BID at first signs/symptoms of atopic dermatitis (itch/redness) to prevent progression to flares.In the event of flares, a moderately potent corticosteroid is permitted as rescue medication. The percentage of patients without flares (e.g. without the need to use corticosteroids as a rescue) in patients treated with Elidel versus placebo cream is compared.
- This design of clinical trials is reflecting the practical use of the drug in the clinic.
Adults with AD
- The use of Elidel at first signs/symptoms of AD substantially reduces the number of flares and consequently reduces or eliminates”) the need for corticosteroid treatment in adults.
Meurer M et al. Dermatology. 2004;208(4):365-372: 130 adults treated for 24 weeks. No flares in 59.7% of Elidel patients compared to 22.1% in the placebo group. 74% reduction of % of days on steroid in adults; almost 4 times fewer days on steroid treatment vs vehicle.

Meurer M et al. Dermatology. 2002;205(3):271-277: 192 adults treated for 24 weeks.No flares in 44.8% of Elidel patients compared to 18,8% in the placebo group.

Children with AD
- The use of Elidel at first signs/symptoms of AD substantially reduces the number of flares and consequently reduces or eliminates the need for corticosteroid treatment in children.

713 patients (2-17 years) treated over a 1 year period.
At 6 months: no flares in 61% of Elidel compared to 34.2% in the placebo group. At 1 year: 50,8% of Elidel compared to 28,3% in the placebo group.

403 patients (1-17 years) treated over 6 weeks.
At 6 weeks,34,8% of patients receiving Elidel were rated as clear or almost clear compared with 18,4% in the vehicle group.
Infants with AD
- The use of Elidel at first signs/symptoms of AD substantially reduces the number of flares and consequently reduces or eliminates the need for corticosteroid treatment in infants.
- (Note: The use of Elidel in infants (less than 2 years of age) is currently NOT approved by Health Canada)
- The use of Elidel at first signs/symptoms of AD substantially reduces the number of flares and consequently reduces or eliminates the need for corticosteroid treatment in infants.

Onset of action
- Elidel rapidly reduces the pruritus associated with atopic dermatitis. Onset of action on symptoms and signs of AD is fast and sustained with no disease rebound after discontinuation

Conclusion
- Elidel cream is a new treatment option for the intermittent long term control of eczema, acting as a flare prevention agent.
- Elidel does not induce skin atrophy.
- Elidel has been shown to be safe according to available clinical data.
- The only significant immediate side effect is a sensation of warmth at site of application, occurring in < 10 % of patients (12 % for the placebo groups).
- Long term safety data are limited to more than 8 years. There is no trend that would suggest toxicity or tachyphylaxis on the long term.
