RESUMEN
BACKGROUND: Determining treatment response for patients with hidradenitis suppurativa (HS) can be challenging due to limitations of current disease activity evaluations. OBJECTIVE: Evaluate the novel, validated endpoint, Hidradenitis Suppurativa Clinical Response (HiSCR) and its utility as an outcome measure. METHODS: Patients with baseline total abscess and inflammatory nodule count (AN count) of at least three and draining fistula count of 20 or fewer comprised the post hoc subpopulation analysed. HiSCR (at least a 50% reduction in total AN count, with no increase in abscess count, and no increase in draining fistula count relative to baseline) and HS-PGA Response [Hidradenitis Suppurativa-Physician's Global Assessment score of clear, minimal, or mild, with at least a 2-grade improvement from baseline] were used to evaluate patient response after adalimumab treatment weekly, every other week, or placebo (1 : 1 : 1). RESULTS: The subpopulation included 132 (85.7%) patients; 70.5% women and 73.5% white. At week 16, HiSCR was achieved by 54.5% receiving weekly adalimumab, 33.3% every other week, and 25.6% placebo and HS-PGA Response was achieved by 20.5% receiving weekly adalimumab, 6.7% every other week and 2.3% placebo. CONCLUSION: HiSCR was more responsive to change than HS-PGA Response in this subpopulation.

BACKGROUND: Psoriasis is associated with poor health-related quality of life, including sleep impairment. OBJECTIVE: To assess the extent of sleep impairment, the effect of adalimumab on sleep and other patient-reported outcomes, and correlations between changes in these outcomes and sleep quality in patients with psoriasis. METHODS: Patients in the 16-week, open-label, Phase IIIb PROGRESS trial had chronic plaque psoriasis and suboptimal response to prior therapy (etanercept, methotrexate or narrowband ultraviolet B phototherapy). Adalimumab was self-injected subcutaneously (80 mg at week 0, then 40 mg every other week from week 1). The focus for this analysis was the Medical Outcomes Study Sleep Scale. Other patient-reported outcomes included the Dermatology Life Quality Index (DLQI), Psoriasis Area and Severity Index (PASI), Physician's Global Assessment, a visual analogue scale for psoriasis/psoriatic arthritis (PsA) pain, and the Work Productivity and Activity Index Questionnaire-Specific Health Problems. RESULTS: Patients with psoriasis had impaired sleep at baseline. The degree of sleep impairment was significantly associated with the extent of work productivity for all sleep measures and, for some sleep measures, was associated with DLQI impairment, clinical severity measured by PASI, the presence of PsA, and depression. Adalimumab treatment significantly improved sleep quality by 15% from baseline, as well as DLQI score, pain and work productivity. The improvement in sleep was partially explained (R(2 ) = 0·16, P < 0·001) by improvements in the objectively measured psoriasis signs in PASI. CONCLUSIONS: Adalimumab treatment improved sleep outcomes and other patient-reported outcomes including health-related quality of life, work productivity, daily activity and disease-related pain.

BACKGROUND: The clinical utility of increasing to weekly adalimumab therapy in patients with psoriasis with inadequate response to every other week (eow) dosing is unknown. OBJECTIVES: (i) To determine the effectiveness of escalating adalimumab dosage from 40 mg eow to 40 mg weekly in patients with < PASI 50 response following ≥ 24 weeks treatment. (ii) To identify retrospectively characteristics of patients likely to benefit from dose escalation using classification and regression tree analysis. (iii) To assess cost implications for allowing dose escalation from the private payers' perspective. METHODS: Patients with moderate-to-severe psoriasis who had received blinded adalimumab 40 mg eow or placebo in antecedent phase II/III studies could enrol in an open-label extension (OLE) and initially receive open-label adalimumab 40 mg eow (EOW population). On/after week 24 (OLE), patients with < PASI 50 response relative to baseline of antecedent study could increase to 40 mg weekly. The dosage escalation population continued on weekly dosing until achieving PASI 75 response, then resumed eow dosing. Study visits were 6/12 weeks after dosage escalation, and every 12 weeks thereafter. The percentage of patients who achieved PASI 75 response following dosage escalation was determined (missing PASI scores imputed as nonresponse). Safety was assessed for the dosage escalation population and for all adalimumab exposure that did not follow dosage escalation in the EOW set. RESULTS: In total, 349/1256 (27·8%) patients underwent dosage escalation (OLE). At 12/24 weeks after dosage escalation, 93/349 (26·6%)/133/349 (38·1%) were PASI 75 responders or resumed eow dosing. Secondary nonresponders, patients weighing ≤ 102 kg, and those with disease duration < 8·3 years were most likely to benefit from dose escalation. Rates of serious/serious infectious/malignant (excluding nonmelanoma skin cancers or lymphoma) adverse events were 6·8/0·9/1·4 events per 100 patient-years (dosage escalation population); comparable rates in the EOW set were 6·5/1·2/0·5 events per 100 patient-years. CONCLUSIONS: Most patients did not require dose escalation. By 12 weeks after dose escalation, one-quarter achieved substantial clinical improvement. Safety results were similar between patients who dosage-escalated and those who did not.
