Detailed Description

Atopic Dermatitis (AD) is a chronic, inflammatory skin disease characterized by dry, red, and itchy patches that can become thickened and lichenified with time. Contact Dermatitis, or Allergic Contact Dermatitis (ACD), is an eczematous reaction in response to an environmental allergen.

The etiology of Atopic Dermatitis (AD) and Allergic Contact Dermatitis (ACD) has not been completely elucidated, and new understandings of underlying mechanisms have expanded and focused treatment regimens and paradigms.

Atopic Dermatitis (AD) is thought to be mediated by Th2 type T cells elaborating a number of cytokines which are blocked in vitro by apremilast. The chronic Atopic Dermatitis (AD) pathway may involve a change to Th1 cytokines. Genetic factors do not contribute as much to the course of Allergic Contact Dermatitis (ACD) as in Atopic Dermatitis (AD). Rather, Allergic Contact Dermatitis (ACD) is a type IV, T-cell mediated, delayed-hypersensitivity reaction that can be self-limited. Similar to Atopic Dermatitis (AD), a number of pro-inflammatory cytokines are involved in recruiting T cells preferentially to the skin: Th1 cytokines, Th2 cytokines, CD8 cytokines, and T-regulatory cytokines. These pathways in Allergic Contact Dermatitis (ACD) are activated by IFN-γ, driven by TNF-α, and as above, apremilast has been shown to block these cytokines in vitro.

Current treatments for Atopic Dermatitis (AD) and Allergic Contact Dermatitis (ACD) include skin care, trigger avoidance (especially in the case of ACD), topical corticosteroids, steroid sparing treatments, antihistamines, topical and systemic antibiotics, and ultraviolet light. For more recalcitrant Atopic Dermatitis (AD) and Allergic Contact Dermatitis (ACD)cases, several immunosuppressive treatments exist.

Subjects with recalcitrant Atopic Dermatitis (AD) or Allergic Contact Dermatitis (ACD)have exhausted conventional systemic treatment options because they do not respond to conventional systemic therapy or cannot use these agents due to side effects or cumulative toxicity.

There is an urgent need to evaluate new therapeutic options in recalcitrant Atopic Dermatitis (AD) and Allergic Contact Dermatitis (ACD). Very few of the available drugs for recalcitrant Atopic Dermatitis (AD) and Allergic Contact Dermatitis (ACD) have reasonable efficacy and safety profiles in this condition, are easily available, or easy to administer. A new treatment strategy is needed for the treatment of recalcitrant contact or atopic dermatitis that would increase efficacy, minimize toxicity for both short and long-term treatment, and be easy to administer. The availability of alternative drug treatment(s) offering safe and effective short and long-term management would significantly benefit subjects with recalcitrant contact or atopic dermatitis.

This study uses a novel oral agent (apremilast) that modulates multiple anti-inflammatory pathways through targeted phosphodiesterase type IV (PDE4) inhibition decreased expression of dermatitis. Apremilast has pharmacodynamic properties with a potential therapeutic benefit for treating inflammatory autoimmune disorders that involve elevated serum cytokine levels, including Atopic Dermatitis (AD) and Allergic Contact Dermatitis (ACD).

Inclusion Criteria:

  • Must understand and voluntarily sign an informed consent form.
  • Must be male or female and aged ≥ 18 years at time of consent.
  • Must be able to adhere to the study visit schedule and other protocol requirements.
  • Must have a documented history of contact or atopic dermatitis for at least 3 months prior to screening visit. Subjects will be asked to bring records at the time of screening visit; if they do not bring these records, subjects will be asked to complete and sign a release of records for which will be sent to the subject's physician. The Investigators will review records to confirm eligibility prior to enrolling a subject into the study.

  • Subjects must fulfill criteria outlined in at least one of the following clinical categories:

    • Unresponsive to standard systemic or topical therapy, as defined by clinical history, in the investigator's opinion, i.e. inadequate response to one or more adequate treatment course (s) of standard systemic therapy including but not limited to: topical steroids, ultraviolet light A [UVA], narrowband ultraviolet B (NBUVB), ultraviolet light B [UVB].
    • Intolerant to or cannot receive (e.g., contraindication to prescribe) standard systemic or topical therapy for contact or atopic dermatitis.

    • tubal ligation;
    • intrauterine device;
    • barrier contraceptive with spermicide;
    • vasectomized partner while on study.
  • A FCBP must agree to have pregnancy tests every 4 weeks while on study medication.
  • Males (including those who have had a vasectomy) must agree to use barrier contraception (latex condoms) when engaging in sexual activity with FCBP while on study medication and for 84 days after taking the last dose of study medication.

  • Inability to provide voluntary consent.

Outcome Measure
Measure Description
Time Frame
Number of Patients Achieving 75% Reduction in Eczema Area and Severity Index (EASI) Score at Week 12 in Reference to Week 0
Time Frame: 12 weeks
EASI scores range from 0 to 72, with higher scores reflecting greater disease severity. Erythema, edema, lichenification, and excoriations/erosions are scored on a scale of 0 (none) to 3 (severe) on 4 anatomic regions of the body: head, trunk, upper limbs, and lower limbs. Degree of involvement on each of the 4 anatomic regions is scored on a scale of 0 to 6. The total qualitative score is multiplied by the degree of involvement for each anatomic region and then multiplied by a constant and summed to yield the EASI score.
