OTEZLA has been studied in over 4,000 patients with psoriasis and psoriatic arthritis worldwide1

ESTEEM, Efficacy and Safety Trial Evaluating the Effects of Apremilast in Psoriasis; LIBERATE, Evaluation in a Placebo-Controlled Study of Oral Apremilast and Etanercept in Plaque Psoriasis.

ESTEEM Study Design1-3

aDoses of apremilast were titrated during the first week of administration.

bA responder was defined as a patient achieving ≥PASI-75 in both ESTEEM 1 and ESTEEM 2 at week 32.

cAt week 32, nonresponders and partial responders (ESTEEM 1) or nonresponders (ESTEEM 2) had the option of adding topical and/or UVB therapy. The decisions could be made at week 32 only but did not need to be initiated at that visit.

Protocol: Randomized, double-blind, multicenter, placebo-controlled trials evaluating the safety and efficacy of apremilast*

Patient population: Adult patients with moderate to severe plaque psoriasis who were candidates for phototherapy or systemic therapy

Extension phase: Patients entering a long-term extension phase could be treated through 5 years

*The use of low-potency topical corticosteroids on the face, axillae, and groin, coal tar shampoo and/or salicylic acid scalp preparations was permitted throughout the studies. In addition, at week 32, subjects who did not achieve a PASI-75 response in ESTEEM 1 or a PASI-50 response in ESTEEM 2 were permitted to use topical psoriasis therapies and/or phototherapy in addition to OTEZLA 30 mg BID.

BSA ≥10%, sPGA ≥3, PASI score ≥12.

BID, twice daily; BSA, body surface area; ESTEEM, Efficacy and Safety Trial Evaluating the Effects of Apremilast in Psoriasis; PASI, Psoriasis Area and Severity Index; sPGA, static Physician Global Assessment; UVB, ultraviolet-B.

LIBERATE Study Design4
  • Protocol: Global, phase 3b, placebo-controlled, double-blind, multicenter study of the safety and efficacy of OTEZLA up to 104 weeks. Patients were randomized 1:1:1 to either OTEZLA twice daily, etanercept once weekly, or placebo through week 16. At week 16, all patients crossed over to the OTEZLA arm*
  • Patient population: Adult patients with chronic plaque psoriasis, for ≥12 months prior to screening, who are naïve to biologic therapy and were candidates for phototherapy and/or systemic therapy

*OTEZLA 30 mg (n = 83), etanercept 50 mg (n = 83), or placebo (n = 84).

Primary endpoint: Proportion of patients on OTEZLA who achieved PASI-75 at week 16 vs placebo.

Patient population also included inadequate response, intolerance, or contraindication to at least one conventional systemic agent and no prior exposure to a biologic for the treatment of psoriatic arthritis or psoriasis.
