Tildrakizumab efficacy and safety in patients with psoriasis and concomitant metabolic syndrome: post hoc analysis of 5-year data from reSURFACE 1 and reSURFACE 2.

BACKGROUND: Limited data are available on long-term efficacy and safety of biologics in patients with psoriasis and metabolic syndrome (MetS), a common comorbidity. OBJECTIVES: This analysis updates tildrakizumab efficacy and safety for up to 5 years in patients with and without MetS. METHODS: This was a post hoc analysis of the double-blind, randomized, placebo-controlled, phase 3 reSURFACE 1 (NCT01722331) and reSURFACE 2 (NCT01729754) trials in adult patients with moderate to severe chronic plaque psoriasis. Analyses included data through Week 244 from patients who continuously received tildrakizumab 100 (TIL100) or 200 mg (TIL200) and entered the extension studies, stratified by baseline MetS status. Efficacy was assessed via Psoriasis Area and Severity Index (PASI) scores. Safety was evaluated from exposure-adjusted incidence rates (EAIRs) of treatment-emergent adverse events (TEAEs). RESULTS: reSURFACE 1 and reSURFACE 2 analyses included 26 and 44 TIL100-treated patients with MetS, 98 and 167 TIL100-treated patients without MetS, 34 and 30 TIL200-treated patients with MetS, and 111 and 130 TIL200-treated patients without MetS, respectively. There were no clinically relevant differences in PASI 75/90/100 response rates at Week 244 between patients with vs without MetS. The proportion of patients with vs without MetS achieving absolute PASI score <3 at Week 244 was 53.8% vs 69.4% and 77.3% vs 80.8% in reSURFACE 1 and 2, respectively, for TIL100-treated patients and 58.8% vs 72.1% and 63.3% vs 72.3%, respectively, for TIL200-treated patients. In both studies, median reduction from baseline PASI score at all time points in patients with vs without MetS was >83% vs >89% for TIL100 and >85% vs >90% for TIL200. Pooled EAIRs of TEAEs, serious TEAEs, and TEAEs of special interest were similar in patients with and without MetS. CONCLUSIONS: Tildrakizumab maintains efficacy and a favorable safety profile over 5 years in patients with psoriasis regardless of MetS status.

The risk of malignancy in patients with secukinumab-treated psoriasis, psoriatic arthritis and ankylosing spondylitis: analysis of clinical trial and postmarketing surveillance data with up to five years of follow-up.

BACKGROUND: Data on the use of biologic therapy and malignancy risk are inconsistent due to limited long-term robust studies. OBJECTIVES: To assess the malignancy risk in patients with secukinumab-treated psoriasis, psoriatic arthritis (PsA) and ankylosing spondylitis (AS). METHODS: This integrated safety analysis from both the secukinumab clinical trial programme and postmarketing safety surveillance data included any patient receiving at least one approved dose of secukinumab with a maximum of 5 years of follow-up. Safety analyses evaluated the rate of malignancy using exposure-adjusted incidence rates [EAIR; incidence rates per 100 patient treatment-years (PTY)]. Standardized incidence ratios (SIRs) were reported using the Surveillance, Epidemiology, and End Results Program (SEER) database as a reference population. Crude incidence of malignancy was also reported using postmarketing surveillance data. RESULTS: Safety data from 49 clinical trials with secukinumab-treated patients were included: 10 685 patients with psoriasis, 2523 with PsA and 1311 with AS. Across indications over a 5-year period, the EAIR of malignancy was 0·85 per 100 PTY [95% confidence interval (CI) 0·74-0·98] in secukinumab-treated patients, corresponding to 204 patients per 23 908 PTY. Overall, the observed vs. expected number of malignancies from secukinumab clinical trial data were comparable, as indicated by an SIR of 0·99 (95% CI 0·82-1·19) across indications. The estimated crude cumulative incidence reporting rate per 100 PTY for malignancy was 0·27 in the postmarketing surveillance data across indications with a cumulative exposure of 285 811 PTY. CONCLUSIONS: In this large safety analysis, the risk of malignancy was low for up to 5 years of secukinumab treatment. These data support the long-term use of secukinumab in these indications.

A randomized phase 2b trial of baricitinib, an oral Janus kinase (JAK) 1/JAK2 inhibitor, in patients with moderate-to-severe psoriasis.

BACKGROUND: Plaque psoriasis is a chronic and often debilitating skin disorder and proinflammatory cytokines are known to play a key role in the disease process. OBJECTIVES: To evaluate the safety and efficacy of baricitinib, an oral Janus kinase (JAK) 1/JAK2 inhibitor, in patients with moderate-to-severe psoriasis in a randomized, double-blind, placebo-controlled, dose-ranging phase 2b study. METHODS: Patients were randomized (n = 271) to receive placebo or oral baricitinib at 2, 4, 8 or 10 mg once daily for 12 weeks (Part A). Dose adjustment for 12 additional weeks was based on percentage improvement in the Psoriasis Area and Severity Index (PASI) score. The primary end point was Psoriasis Area and Severity Index (PASI) 75% (PASI-75) at 12 weeks for North American patients (n = 238); secondary end points were safety and efficacy measures in the entire population. RESULTS: At week 12, more North American patients in the 8-mg (43%) and 10-mg (54%) baricitinib groups than in placebo group (17%; P < 0·05) achieved PASI-75. All baricitinib-treated groups had greater mean changes from baseline in their PASI scores (P < 0·05) at 12 weeks and (except 2 mg) had higher rates of PASI-50 than the placebo group; statistically significant PASI-90 responses were achieved in the 8-mg and 10-mg groups at 8 and 12 weeks. More than 81% of PASI-75 responders maintained their scores through 24 weeks. During Part A, study discontinuations due to adverse events (AEs) were 0%, 0%, 2·8%, 6·3% and 5·8% and treatment-emergent AE rates were 44%, 50%, 47%, 58% and 64% for placebo and 2-, 4-, 8- and 10-mg baricitinib groups, respectively. No opportunistic infections were observed in any treatment group. Dose-dependent changes in laboratory values were observed. CONCLUSIONS: Patients with moderate-to-severe psoriasis treated with baricitinib for 12 weeks achieved significant improvements in PASI-75.

Tofacitinib, an oral Janus kinase inhibitor, for the treatment of chronic plaque psoriasis: results from two randomized, placebo-controlled, phase III trials.

BACKGROUND: Tofacitinib is an oral Janus kinase inhibitor being investigated for psoriasis. OBJECTIVES: To determine the 16-week efficacy and safety of two oral tofacitinib doses vs. placebo in patients with moderate-to-severe chronic plaque psoriasis. METHODS: Patients in two similarly designed phase III studies (OPT Pivotal 1, NCT01276639, n = 901; OPT Pivotal 2, NCT01309737, n = 960) were initially randomized 2 : 2 : 1 to tofacitinib 10 or 5 mg or placebo, twice daily. Coprimary efficacy end points (week 16) included the proportion of patients achieving Physician's Global Assessment (PGA) of 'clear' or 'almost clear' (PGA response) and the proportion achieving ≥ 75% reduction in Psoriasis Area and Severity Index (PASI 75). RESULTS: Across OPT Pivotal 1 and OPT Pivotal 2, 745 patients received tofacitinib 5 mg, 741 received tofacitinib 10 mg and 373 received placebo. At week 16, a greater proportion of patients achieved PGA responses with tofacitinib 5 and 10 mg twice daily vs. placebo (OPT Pivotal 1, 41·9% and 59·2% vs. 9·0%; OPT Pivotal 2, 46·0% and 59·1% vs. 10·9%; all P < 0·001). Higher PASI 75 rates were observed with tofacitinib vs. placebo (OPT Pivotal 1, 39·9%, 59·2% and 6·2%, respectively, for tofacitinib 5 and 10 mg twice daily and placebo; OPT Pivotal 2, 46·0%, 59·6% and 11·4%; all P < 0·001 vs. placebo). Adverse event (AE) rates appeared generally similar across groups; rates of serious AEs, infections, malignancies and discontinuations due to AEs were low. Twelve patients reported herpes zoster across the tofacitinib treatment groups in both studies vs. none in the respective placebo groups. The most common AE across groups was nasopharyngitis. CONCLUSIONS: Oral tofacitinib demonstrated significant efficacy vs. placebo during the initial 16 weeks of treatment in patients with moderate-to-severe psoriasis. Safety findings were consistent with prior studies.

Psoriasis and pregnancy: hormone and immune system interaction.

BACKGROUND: Various hormonal states are known to be associated with the waxing and waning of psoriasis. Patients with psoriasis commonly experience changes in their cutaneous disease during pregnancy or post partum. OBJECTIVE: We evaluated 100 women with psoriasis by questionnaire and interview. The women had been seen at the Baylor Psoriasis Center, Dallas, and had experienced a pregnancy while having psoriasis. The answers were sorted and tabulated. In addition, we reviewed the literature to ascertain possible causes of clinical changes in psoriasis during pregnancy. RESULTS: Ninety questionnaires were completed. Sixty-nine women (76.7%) described a change in their psoriasis during pregnancy with 57 (63.3%) noting improvement. Seventy-nine patients (87.7%) had a postpartum flare, most within 4 months of delivery. CONCLUSIONS: The majority of women with psoriasis, who become pregnant, experience a change, usually an improvement, in their cutaneous disease. Pregnancy is associated with hormonal changes in estrogens and progesterone resulting in a state of altered immune surveillance.

Methotrexate and reproduction in men: case report and recommendations.

Methotrexate has been used in the treatment of recalcitrant psoriasis for more than 35 years. We examined the significance of impaired spermatogenesis in a young man undergoing methotrexate treatment for severe psoriasis with associated arthritis. A medical geneticist was consulted and a review of the literature was performed. Genetic abnormalities that could lead to mutagenesis include chromosomal abnormalities and single-gene mutations. These aspects are considered and recommendations are made for counseling men undergoing methotrexate therapy so that risks and options can be considered.

Oral lesions in patients with psoriasis: a controlled study.

Stomatitis areata migrans was found in 5.4 percent of patients with psoriasis compared to 1 percent of control patients, while benign migratory glossitis was identified in 10.3 percent of patients with psoriasis and 2.5 percent of control patients. The association of these disorders with psoriasis indicates that they may be manifestations of psoriasis of the oral mucosa.

Mometasone furoate ointment and cream 0.1 percent in treatment of psoriasis: comparison with ointment and cream formulations of fluocinolone acetonide 0.025 percent and triamcinolone acetonide 0.1 percent.

Mometasone furoate (Elocon) is a newly formulated and unique medium-potency synthetic 17-heterocyclic corticosteroid. The efficacy and safety of the ointment and cream formulations (0.1 percent) of the corticosteroid, administered once daily, were compared with those of the ointment and cream formulations of fluocinolone acetonide 0.025 percent administered three times daily and triamcinolone acetonide 0.1 percent administered twice daily in four multicenter clinical studies. They were conducted involving psoriasis patients with chronic and moderate to severe disease. Evaluation of change in disease sign scores indicated that mometasone ointment, applied once daily, was significantly more effective (P less than 0.01) than fluocinolone ointment, applied three times daily, and triamcinolone ointment, applied twice daily. The cream formulation of mometasone was significantly more effective (p less than 0.001) than fluocinolone cream, applied three times daily, and equivalent to triamcinolone cream, applied twice daily. The incidence of local adverse experiences following treatment with the ointment or cream formulations of mometasone was minimal. Mometasone ointment and cream provide a highly effective once-a-day treatment for moderate to severe psoriasis with minimal risk of side effects.

Resistant childhood psoriasis: an analysis of patients seen in a day-care center.

During a three-and-one-half-year period, 54 children aged 1 to 16 years, all of whom had resistant psoriasis, were seen at a day-care center. The female: male ratio was 3:2. In 74% of the patients, the onset of psoriasis occurred when they were below 10 years of age. Papules and plaques occurred in 78% of cases, guttate lesions in 16%, and nail involvement in 21%. A family history of psoriasis was present in 69% of cases, preceding upper respiratory tract infections occurred in 35%, and prior cradle cap and/or diaper rash in 50%. In the day-care center, Goeckerman therapy was given to 31 children. The average duration of treatment was 12 days, producing maximum clearing of over 90% in 64% of patients, with substantial improvement in the remainder. After three months, the psoriasis in 83% of these patients was over 90% clear; 43% showed maximum clearing at one year. Two patients were treated with anthralin and ultraviolet light alone, one with good results. One patient with nail psoriasis alone was not treated. The remaining 20 patients were either unable to attend for treatment at the center or had less extensive psoriasis. Home treatment was prescribed for them, with less satisfactory results.

A surface impression and scanning electron microscopic study of porokeratosis of Mibelli.

A silicone rubber impression technique, together with scanning electron microscopy, was used to study the surface detail of porokeratosis of Mibelli. The lesions are propagated by a bud-like spreading of the active edge. The keratotic rim is produced by the condensation of squamous cells from both within and without the lesion.
