Abstract

Background Apremilast (APR), an oral PDE4 inhibitor, was effective in phase 3, randomized, placebo (PBO)-controlled trials assessing treatment of moderate to severe plaque psoriasis (ESTEEM 1 and 2) and psoriatic arthritis (PsA; PALACE 1–3).

Objectives We report incidence of MACE, malignancies, and serious infections (SIs; opportunistic and non-opportunistic) in pts receiving APR 30 mg BID (APR30) for ≥156 wks in a pooled analysis of these studies.

Methods Incidence rates and exposure-adjusted incidence rates (EAIR)/100 pt-yrs of MACE, malignancies, SIs, and serious opportunistic infections (SOIs) are reported for 0 to 16 wks, 0 to ≤52 wks, and the APR-exposure period (0 to ≥156 wks) for pts receiving APR30 any time during the studies, through February 2015; ∼30% (n=575) of pts received >3 yrs (>156 wks) of APR exposure.

Results 2,242 pts were included in the safety analysis for 0 to 16 wks (PBO n=913, pt-yrs exposure [py]=260.2; APR30 n=1,329, py=377.8); 1,905 pts received APR30 during the APR-exposure period, representing 3,527.5 py; exposure during 0 to ≤52 wks was 1,524.5 py. At baseline 64.2% of PsA pts (PALACE 1–3) in the APR30 group were receiving concomitant DMARDs (including methotrexate). Incidence of MACE with APR30 was low and comparable to PBO during 0 to 16 wks. During 0 to ≤52 wks and the APR-exposure period, incidence of MACE (EAIR/100 pt-yrs) remained low (Table). Incidence rates (EAIR/100 pt-yrs) of hematologic malignancies, non-melanoma skin cancers, and solid tumors were similar with PBO (0.0, 1.2, 0.4) and APR30 (0.0, 1.3, 0.3) during 0 to 16 wks; incidence rates remained low during 0 to ≤52 wks and the APR-exposure period (Table). During 0 to 16 wks, the overall rate of infections (serious and non-serious) was low and comparable between pts receiving PBO (20.6%) and APR30 (24.8%). The overall rate of infections (serious and non-serious) was 42% during 0 to ≤52 wks and comparable to rates during the PBO-controlled period (0 to 16 wks); the majority of reported infections (URTI, nasopharyngitis, sinusitis) were not serious. During the PBO-controlled period (0 to 16 wks), rates of SIs with APR30 were low and comparable to PBO; no SOIs were reported. During 0 to ≤52 wks, the overall rate of SIs was low (0.6%; EAIR/100 pt-yrs: 0.7). The rate of SIs remained low (1.8%; EAIR/100 pt-yrs: 1.0) during the long-term cumulative APR-exposure period (0 to ≥156 wks) (Table). No clustering of any particular event was noted with respect to SIs; most events occurred in only 1 pt. No clinical reactivation of tuberculosis was reported with long-term APR30 exposure (0 to ≥156 wks). The rate of marked hematologic abnormalities remained low with long-term APR exposure.

Conclusions Incidence of MACE, malignancies, and SIs was low in pts with psoriasis and PsA receiving APR30 for ≥156 wks. No new safety signals or SOIs were observed over time with APR30.
