Tofacitinib versus etanercept or placebo in patients with moderate to severe chronic plaque psoriasis: patient-reported outcomes from a Phase 3 study.

ABSTRACT: Tofacitinib is an oral Janus kinase inhibitor that is being investigated for psoriasis. Psoriasis impacts on physical and psychological well-being; improvements in health-related quality of life (HRQoL) with etanercept in psoriasis are well documented.To evaluate HRQoL with tofacitinib, vs. placebo or etanercept, in the Phase 3, randomized, placebo-controlled, non-inferiority, Oral-treatment Psoriasis Trial (OPT) Compare Study (NCT01241591).Adults with moderate to severe chronic plaque psoriasis were randomized 3:3:3:1 to tofacitinib 10 or 5 mg twice daily (BID), etanercept 50 mg twice weekly or placebo, for 12 weeks. Patient-reported outcomes (PROs) included Dermatology Life Quality Index (DLQI), Itch Severity Item and Patient Global Assessment of psoriasis.At baseline, 83.4% (911/1092) of patients had a DLQI score ranging between 6 and 30, indicating a substantial burden of disease. By Week 12, 47.3%, 43.6% and 30.9% of patients in the tofacitinib 10 mg BID, etanercept and tofacitinib 5 mg BID groups, respectively, had a DLQI score of 0 or 1 (no effect of psoriasis on QoL) vs. 7.8% for placebo (all P < 0.0001). Tofacitinib significantly reduced itch vs. placebo (P < 0.05 both doses) and etanercept (P < 0.0001 both doses) within 1 day of starting treatment. Furthermore, reductions in itch were greater with tofacitinib 10 mg BID, vs. etanercept, at Weeks 2-12 (all time points P < 0.05). At Week 2, an Itch Severity Item score of 'little or no itch' was more frequent with tofacitinib 10 mg (68.6%) vs. etanercept (57.4%) and placebo (12.2%), and the PtGA response rate was significantly greater with tofacitinib 10 mg vs. placebo (P < 0.05).Oral tofacitinib provided significant improvements across multiple PROs by Week 12. Improvements with tofacitinib 10 mg BID were comparable to etanercept, and improvements in itch were greater and more rapid with tofacitinib 10 mg BID.

Project description:BackgroundApremilast, an oral, small-molecule phosphodiesterase 4 inhibitor, has demonstrated efficacy in patients with moderate-to-severe psoriasis.ObjectiveEvaluate efficacy and safety of apremilast vs. placebo in biologic-naive patients with moderate-to-severe plaque psoriasis and safety of switching from etanercept to apremilast in a phase IIIb, randomized, double-blind, placebo-controlled study (NCT01690299).MethodsTwo hundred and fifty patients were randomized to placebo (n = 84), apremilast 30 mg BID (n = 83) or etanercept 50 mg QW (n = 83) through Week 16; thereafter, all patients continued or switched to apremilast through Week 104. The primary efficacy endpoint was achievement of PASI-75 at Week 16 with apremilast vs. placebo. Secondary endpoints included achievement of PASI-75 at Week 16 with etanercept vs. placebo and improvements in other clinical endpoints vs. placebo at Week 16. Outcomes were assessed through Week 52. This study was not designed for apremilast vs. etanercept comparisons.ResultsAt Week 16, PASI-75 achievement was greater with apremilast (39.8%) vs. placebo (11.9%; P < 0.0001); 48.2% of patients achieved PASI-75 with etanercept (P < 0.0001 vs. placebo). PASI-75 response was maintained in 47.3% (apremilast/apremilast), 49.4% (etanercept/apremilast) and 47.9% (placebo/apremilast) of patients at Week 52. Most common adverse events (≥5%) with apremilast, including nausea, diarrhoea, upper respiratory tract infection, nasopharyngitis, tension headache and headache, were mild or moderate in severity; diarrhoea and nausea generally resolved in the first month. No new safety or tolerability issues were observed through Week 52 with apremilast.ConclusionApremilast demonstrated significant efficacy vs. placebo at Week 16 in biologic-naive patients with psoriasis, which was sustained over 52 weeks, and demonstrated safety consistent with the known safety profile of apremilast. Switching from etanercept to apremilast did not result in any new or clinically significant safety findings, and efficacy was maintained with apremilast through Week 52.
