Efficacy and Safety of Apremilast in Systemic- and Biologic-Naive Patients With Moderate Plaque Psoriasis: 52-Week Results of UNVEIL.

BACKGROUND: Many patients with moderate plaque psoriasis are undertreated despite broadening treatment options. In the phase IV UNVEIL study, oral apremilast demonstrated efficacy and safety in systemic-naive patients with chronic moderate plaque psoriasis with lower psoriasis-involved body surface area (BSA; 5%-10%) during the 16-week, double-blind, placebo-controlled phase. We describe efficacy and safety of apremilast in this population through week 52 in UNVEIL.

METHODS: Patients with moderate plaque psoriasis (BSA 5%-10%; static Physician's Global Assessment [sPGA] score of 3 [moderate]) and naive to systemic therapies for psoriasis were randomized (2:1) to receive apremilast 30 mg twice daily or placebo for 16 weeks. At week 16, patients continued on apremilast (apremilast/apremilast) or were switched from placebo to apremilast (placebo/apremilast) through week 52 (open-label apremilast treatment phase). Efficacy assessments included the product of sPGA and BSA (PGAxBSA) (mean percentage change from baseline; ≥75% reduction from baseline [PGAxBSA-75]), sPGA response (achievement of score of 0 [clear] or 1 [almost clear]), and the Dermatology Life Quality Index (DLQI; mean change from baseline).

RESULTS: A total of 136 patients completed the 52-week analysis period (placebo/apremilast, n=50/64; apremilast/apremilast, n=86/121). At week 52, improvements in all efficacy end points observed at week 16 were maintained in the apremilast/apremilast group (mean percentage change from baseline in PGAxBSA: -55.5%; PGAxBSA-75: 42.1%; sPGA response: 33.1%; mean change from baseline in DLQI score: -4.4); similar improvements emerged in the placebo/apremilast group after switching to apremilast. The most common adverse events (≥5% of patients) through week 52 were diarrhea (28.0%), nausea (19.0%), headache (15.2%), nasopharyngitis (10.4%), upper respiratory tract infection (7.1%), vomiting (5.7%), and decreased appetite (5.2%).

CONCLUSIONS: Apremilast was effective in systemic-naive patients with moderate plaque psoriasis with BSA 5%-10%; efficacy was sustained through week 52. No new safety signals emerged with continued apremilast exposure.

Long-term safety and tolerability of apremilast in patients with psoriasis: Pooled safety analysis for ≥156 weeks from 2 phase 3, randomized, controlled trials (ESTEEM 1 and 2).

BACKGROUND: Randomized, controlled trials demonstrated efficacy and safety of apremilast for moderate-to-severe plaque psoriasis and psoriatic arthritis. OBJECTIVE: Assess long-term safety of oral apremilast in psoriasis patients. METHODS: Safety findings are reported for 0 to ≥156 weeks from the Efficacy and Safety Trial Evaluating the Effects of Apremilast in Psoriasis (ESTEEM) 1 and 2. RESULTS: The 0 to ≥156-week apremilast-exposure period included 1184 patients treated twice daily with apremilast 30 mg (1902.2 patient-years). During 0 to ≤52 weeks, the adverse events (AEs) that occurred in ≥5% of patients included diarrhea, nausea, upper respiratory tract infection, nasopharyngitis, tension headache, and headache. From 0 to ≥156 weeks, no new AEs (affecting ≥5% of the population) were reported. AEs, serious AEs, and study drug discontinuations caused by AEs did not increase with long-term exposure. During the 0 to ≥156-week period, the rates of major cardiac events (exposure-adjusted incidence rate [EAIR] 0.5/100 patient-years), malignancies (EAIR 1.2/100 patient-years), depression (EAIR 1.8/100 patient-years), or suicide attempts (EAIR 0.1/100 patient-years) did not increase in comparison with the rates found during the 0 to ≤52-week period. No serious opportunistic infections, reactivation of tuberculosis, or clinically meaningful effects on laboratory measurements were reported. LIMITATIONS: This study had a high dropout rate (21% of patients ongoing >156 weeks); most were unrelated to safety concerns. CONCLUSIONS: Apremilast demonstrated an acceptable safety profile and was generally well tolerated for ≥156 weeks.

Evaluation of the Physician Global Assessment and Body Surface Area Composite Tool for Assessing Psoriasis Response to Apremilast Therapy: Results from ESTEEM 1 and ESTEEM 2.

BACKGROUND: The Physician Global Assessment and Body Surface Area (PGAxBSA) composite tool is a simple, effective alternative for measuring psoriasis severity. OBJECTIVE: To evaluate the product of PGAxBSA as a sensitive alternative to the Psoriasis Area and Severity Index (PASI) for assessing disease severity and therapeutic response with data collected from the phase 3 ESTEEM 1 and 2 trials. METHODS: This post hoc analysis included 836 patients randomized to apremilast 30 mg BID at baseline (ESTEEM 1, n=562; ESTEEM 2, n=274). Spearman correlation coefficients were used to compare PGAxBSA, PASI, and the Dermatology Life Quality Index (DLQI). Concordance between PGAxBSA and PASI was evaluated for 50%/75%/90% improvement from baseline at week 16. RESULTS: In ESTEEM 1 and 2, PGAxBSA and PASI exhibited significant positive correlations for measuring disease severity at baseline (r≥0.757) and week 16 (r≥0.807). At week 16, ≥79% concordance was observed between PGAxBSA and PASI for 75% and 90% improvement from baseline; greater concordance (>88.0%) was observed using 50% improvement from baseline. At week 16, PGAxBSA and PASI were moderately correlated with DLQI. LIMITATIONS: Analysis was limited to patients with baseline BSA ≥10% and static PGA ≥3. CONCLUSIONS: In patients with moderate to severe psoriasis, PGAxBSA is correlated with PASI and sensitive to therapeutic response.

Efficacy and Safety of Apremilast in Patients With Moderate Plaque Psoriasis With Lower BSA: Week 16 Results from the UNVEIL Study.

INTRODUCTION: Many options are available for patients with moderate to severe plaque psoriasis. Patients with moderate disease, however, are often undertreated and do not achieve satisfactory clearance. UNVEIL (NCT02425826) assessed efficacy and safety of apremilast in patients with chronic moderate plaque psoriasis.

METHODS: Patients with psoriasis body surface area (BSA) 5% to 10% and static Physician's Global Assessment (sPGA) score of 3 (moderate) without prior exposure to systemics were randomized (2:1) to apremilast 30 mg twice daily or placebo for 16 weeks. The primary efficacy endpoint was mean percentage change in the product of sPGA and BSA scores (PGAxBSA).

RESULTS: Of 221 patients (placebo, n=73; apremilast, n=148), >80% had received prior topical therapy. At week 16, apremilast yielded a significantly greater percentage change from baseline in PGAxBSA (-48.1%) vs placebo (-10.2^; P less than 0.0001). Dermatology Life Quality Index scores were significantly improved with apremilast (-4.8) vs placebo (-2.4; P=0.0008). Mean improvements in the Treatment Satisfaction Questionnaire for Medication, version II, were greater with apremilast vs placebo for global satisfaction (63.2 vs 48.7; P less than 0.0001) and treatment effectiveness (57.3 vs 38.8; P less than 0.0001). Most adverse events were mild or moderate; most common were diarrhea, headache, nausea, upper respiratory tract infection, decreased appetite, and vomiting.

CONCLUSION: Apremilast was effective and well tolerated, significantly improved quality of life, and was associated with high patient satisfaction in systemic-naive, post-topical patients with moderate plaque psoriasis.

Apremilast, an oral phosphodiesterase-4 inhibitor, in the treatment of palmoplantar psoriasis: Results of a pooled analysis from phase II PSOR-005 and phase III Efficacy and Safety Trial Evaluating the Effects of Apremilast in Psoriasis (ESTEEM) clinical trials in patients with moderate to severe psoriasis.

BACKGROUND: Difficult-to-treat palmoplantar psoriasis has a disproportionately negative impact on quality of life. OBJECTIVE: We evaluated the efficacy and safety of apremilast in palmoplantar psoriasis. METHODS: A post hoc analysis of data pooled from phase IIb (PSOR-005) and phase III (Efficacy and Safety Trial Evaluating the Effects of Apremilast in Psoriasis [ESTEEM] 1 and 2) clinical studies was conducted to determine the effect of apremilast 30 mg twice daily versus placebo at week 16 in a subset of patients with moderate to severe plaque psoriasis with active palmoplantar psoriasis (baseline Palmoplantar Psoriasis Physician Global Assessment [PPPGA] score ≥1). RESULTS: Significantly more patients taking apremilast with moderate to severe palmoplantar psoriasis (baseline PPPGA score ≥3) achieved PPPGA score 0 (clear) or 1 (almost clear) compared with placebo at week 16 (48% vs 27%; P = .021). At week 16, 46% of the apremilast group with baseline PPPGA score 1 or higher achieved a PPPGA score of 0 versus 25% of the placebo group (P < .001); 59% of the apremilast group had a PPPGA score of 0 or 1 with 1-point or more improvement versus 39% receiving placebo (P < .001). LIMITATIONS: This post hoc analysis was limited to 16 weeks and did not assess palmoplantar pustules, lesion localization, or surface area involvement. CONCLUSION: Apremilast may be a useful oral treatment option for patients with moderate to severe palmoplantar plaque psoriasis.

Apremilast, an oral phosphodiesterase 4 inhibitor, in patients with difficult-to-treat nail and scalp psoriasis: Results of 2 phase III randomized, controlled trials (ESTEEM 1 and ESTEEM 2).

BACKGROUND: In the phase III double-blind Efficacy and Safety Trial Evaluating the Effects of Apremilast in Psoriasis (ESTEEM) 1 and 2, apremilast, an oral phosphodiesterase 4 inhibitor, demonstrated efficacy in moderate to severe psoriasis. OBJECTIVE: We sought to evaluate efficacy of apremilast in nail/scalp psoriasis in ESTEEM 1 and 2. METHODS: A total of 1255 patients were randomized (2:1) to apremilast 30 mg twice daily or placebo. At week 16, placebo patients switched to apremilast through week 32, followed by a randomized withdrawal phase to week 52. A priori efficacy analyses included patients with nail (target nail Nail Psoriasis Severity Index score ≥1) and moderate to very severe scalp (Scalp Physician Global Assessment score ≥3) psoriasis at baseline. RESULTS: At baseline, 66.1% and 64.7% of patients had nail psoriasis; 66.7% and 65.5% had moderate to very severe scalp psoriasis in ESTEEM 1 and 2. At week 16, apremilast produced greater improvements in Nail Psoriasis Severity Index score versus placebo; mean percent change: -22.5% versus +6.5% (ESTEEM 1; P < .0001) and -29.0% versus -7.1% (ESTEEM 2; P = .0052). At week 16, apremilast produced greater NAPSI-50 response (50% reduction from baseline in target nail Nail Psoriasis Severity Index score) versus placebo (both studies P < .0001) and ScPGA response (Scalp Physician Global Assessment score 0 or 1) versus placebo (both studies P < .0001). Improvements were generally maintained over 52 weeks in patients with Psoriasis Area and Severity Index response at week 32. LIMITATIONS: Baseline randomization was not stratified for nail/scalp psoriasis. CONCLUSION: Apremilast reduces the severity of nail/scalp psoriasis.

Effects of Apremilast on Pruritus and Skin Discomfort/Pain Correlate With Improvements in Quality of Life in Patients With Moderate to Severe Plaque Psoriasis.

Pruritus and skin discomfort/pain negatively impact health-related quality of life (HRQoL). The effects of apremilast, an oral phosphodiesterase inhibitor, on pruritus, skin discomfort/pain, and patient global assessment of psoriasis disease activity (PgAPDA) were assessed in moderate/severe chronic plaque psoriasis patients in the phase 3 ESTEEM trials. Significant improvements in pruritus and skin discomfort/pain observed at Week 2 with apremilast versus placebo (both studies, p < 0.0001) were sustained through Week 32. Among apremilast-treated patients, improvements in pruritus visual analog scale (VAS) scores correlated with Dermatology Life Quality Index scores (rs = 0.55 [Week 16], rs≥0.51 [Week 32]; both studies, p < 0.001). PgAPDA correlated with improvements in pruritus (rs≥0.56 [Week 16]; rs≥0.53 [Week 32]; both studies, p < 0.001) and skin discomfort/pain (rs ≥0.54 [Week 16]; rs≥0.53 [Week 32]; both studies, p < 0.001) VAS scores. Apremilast provided rapid and sustained improvement in pruritus and skin discomfort/pain, symptoms not typically captured in psoriasis assessments (e.g., PASI) that contribute significantly to patients' disease severity and HRQoL perceptions.

Reduced dose and duration of peginterferon alfa-2b and weight-based ribavirin in patients with genotype 2 and 3 chronic hepatitis C.

BACKGROUND & AIMS: There is increasing interest in identifying patients with chronic hepatitis C genotype 2 or 3 infection in whom it is possible to lower the burden of therapy while retaining high levels of efficacy. METHODS: Treatment-naive patients with chronic hepatitis C genotype 2/3 infection were randomized to receive peginterferon alfa-2b (1.5µg/kg/wk) for 24weeks (group A); peginterferon alfa-2b (1.0µg/kg/wk) for 24weeks (group B); or peginterferon alfa-2b (1.5µg/kg/wk) for 16weeks (group C), each in combination with weight-based ribavirin (800-1200mg/d). The study population comprised two cohorts: the Hep-Net cohort enrolled in Germany and an International cohort enrolled at study sites throughout Europe and Asia. The primary end point was sustained virological response (SVR). RESULTS: The study included 682 patients; 80.2% had genotype 3 infection. In the intent-to-treat population, SVR rates were 66.5%, 64.3%, and 56.6% in groups A, B, and C, and were similar in Asian and white patients. Treatment differences (A vs. B and A vs. C) failed to reach the predefined margin for noninferiority of -10%; and thus groups B and C failed to show noninferiority relative to group A. Among patients with undetectable HCV RNA at week 4, SVR rates were 75.3%, 75.9%, and 72.4%, respectively. Relapse rates were 17.8%, 16.3%, and 29.3%, respectively. Treatment-emergent serious adverse events were highest in group A and lowest in group C, and adverse events leading to discontinuation were similar across treatment arms. CONCLUSIONS: For patients with chronic hepatitis C genotype 2/3 infection, 24weeks of peginterferon alfa-2b (1.5µg/kg/wk) plus weight-based ribavirin remains a standard-of-care therapy; however, treatment for 16weeks may be considered for patients with undetectable HCV RNA at week 4 of the treatment.
