ESTEEM 1 & ESTEEM 2 Details
ESTEEM Study Design
LIBERATE Study Design
ESTEEM® 1 and ESTEEM 21-3
In ESTEEM 1, patients were switched to Otezla if they lost their PASI‑75, but no later than at week 52. In ESTEEM 2, patients were switched to Otezla if they lost 50% of the PASI improvement obtained at week 32 compared to baseline, but no later than at week 52.
Doses of Otezla were titrated during the first week of administration.
A responder was defined as a patient achieving ≥PASI-75; a partial responder was defined as a patient achieving PASI‑50 to PASI‑74; a nonresponder was defined as a patient achieving <PASI‑50 in both ESTEEM 1 and ESTEEM 2 at week 32.
At week 32, nonresponders and partial responders (ESTEEM 1) or nonresponders only (ESTEEM 2) had the option of adding topical and/or UVB therapy. The decision could be made at week 32 and was based on the discretion of the investigator.
BID, twice daily; ESTEEM, Efficacy and Safety Trial Evaluating the Effects of Apremilast in Psoriasis; PASI, Psoriasis Area and Severity Index.
Weeks 0 to 16 (placebo-controlled phase): Patients were randomized 2:1 to Otezla twice daily or placebo2,3
Weeks 16 to 32 (maintenance phase): All patients received Otezla2,3
Weeks 32 to 52 (withdrawal phase)2,3
Patients originally randomized to Otezla who achieved at least a 75% reduction in PASI score (PASI-75) in ESTEEM 1, or at least a 50% reduction in PASI score (PASI-50) in ESTEEM 2 at week 32, were re-randomized 1:1 to either placebo or Otezla. Patients who were re-randomized to placebo and who lost their PASI-75 response (ESTEEM 1), or 50% of the improvement that they achieved at week 32 compared to baseline (ESTEEM 2), were re-treated with Otezla, but no later than week 52. Patients who did not achieve the designated PASI response by week 32 had the option of adding topical and/or UVB therapy
Patients originally randomized to placebo and transitioned to Otezla, who then achieved at least PASI-75 in ESTEEM 1, or at least PASI-50 in ESTEEM 2, at week 32, were allowed to continue on Otezla. Patients who did not achieve the designated PASI response by week 32 had the option of adding topical and/or UVB therapy
Weeks 52 to 260 (long-term extension phase)2,3
Patients entering a long-term extension phase could be treated through 5 years
Otezla was evaluated in 2 multicenter, double-blind, placebo-controlled trials of similar design. Patients ≥18 years of age (N = 1257) with moderate to severe plaque psoriasis were randomized to placebo (n = 419) or Otezla (n = 836) given orally twice daily. These studies had a similar design through week 32.2-4
