Safety of biologic therapy in combination with methotrexate in moderate to severe psoriasis: a cohort study from the BIOBADADERM registry.

BACKGROUND: Safety is an important consideration in decisions on treatment for patients with moderate-to-severe psoriasis and the study of drug safety is the main purpose of the BIOBADADERM registry. The combination of a biologic agent and a conventional systemic drug [generally methotrexate (MTX)] is a common treatment in clinical practice. However, there is a paucity of evidence from real-world practice on the safety of such combination regimens in the treatment of psoriasis. OBJECTIVES: The primary objective of this study was to ascertain whether the use of regimens combining biologic drugs with MTX in the management of moderate-to-severe psoriasis increases the risk of adverse events (AEs) or serious AEs (SAEs). We compared monotherapy using tumour necrosis factor (TNF), interleukin (IL)-17 and IL-23 inhibitors with the use of the same drugs in combination with MTX. METHODS: Using data from the BIOBADADERM registry, we compared biologic monotherapies with therapies that were combined with MTX. We estimated adjusted incidence rate ratios (aIRR) using a random effects Poisson regression with 95% confidence intervals for all AEs, SAEs, infections and serious infections and other AEs by system organ class. RESULTS: We analysed data from 2829 patients and 5441 treatment cycles, a total of 12 853 patient-years. The combination of a biologic with MTX was not associated with statistically significant increases in overall risk of AEs or SAEs in any treatment group. No increase in the total number of infections or serious infections in patients receiving combined therapy was observed for any group. However, treatment with a TNF inhibitor combined with MTX was associated with an increase in the incidence of gastrointestinal AEs (aIRR 2.50, 95% CI 1.57-3.98; P < 0.002). CONCLUSIONS: The risk of AEs and SAEs was not significantly increased in patients with moderate-to-severe psoriasis receiving different classes of biologic drugs combined with MTX compared with those on biologic monotherapy.

Secukinumab demonstrates superiority over narrow-band ultraviolet B phototherapy in new-onset moderate to severe plaque psoriasis patients: Week 52 results from the STEPIn study.

BACKGROUND: Biologic treatments have been studied mainly in patients with a long-term history of psoriasis and previous treatment failures. OBJECTIVES: The purpose of this primary analysis of the STEPIn study is to determine whether early intervention with secukinumab in patients with new-onset moderate to severe plaque psoriasis is superior to standard of care treatment with narrow band ultraviolet B (nb-UVB) phototherapy. METHODS: The STEPIn study is a randomized, open-label, multicentre study to investigate early intervention with 52 weeks of secukinumab 300 mg administered subcutaneously versus standard treatment with nb-UVB phototherapy in patients with new-onset (≤12 months) moderate to severe plaque psoriasis (NCT03020199). The primary and additional secondary endpoints were ≥90% improvement in Psoriasis Area and Severity Index (PASI 90) at Week 52 and Investigator's Global Assessment (IGA mod 2011) 0/1 response at Week 52, respectively. RESULTS: In the secukinumab and nb-UVB study arms, 77/80 and 76/80 randomized patients received at least one dose of study treatment, respectively. The primary endpoint was achieved: 91.1% (70/77) of patients achieved a PASI 90 response at Week 52 in the secukinumab arm versus 42.3% (32/76) in the nb-UVB arm (p < 0.0001, odds ratio [OR] estimate [95% confidence intervals, CI] = 16.3 [5.6, 46.9]). The additional secondary endpoint was also achieved: 85.7% of patients achieved an IGA 0/1 response at Week 52 in the secukinumab arm versus 36.8% in the nb-UVB arm (p < 0.0001). The safety data were consistent with the safety profiles of secukinumab and nb-UVB with no new or unexpected safety signals. CONCLUSIONS: Secukinumab was superior to nb-UVB in treating patients with new-onset moderate to severe plaque psoriasis. The high and sustained skin clearance observed indicates that biologic treatment for psoriasis may be more effective if used early in the disease course.

Secukinumab demonstrates efficacy, safety, and tolerability upon administration by 2 ml autoinjector in adult patients with plaque psoriasis: 52-week results from MATURE, a randomized, placebo-controlled trial.

Convenient administration is an important factor for treatment adherence in patients with psoriasis. MATURE study reports the efficacy, safety, tolerability, and pharmacokinetics (PKs) of secukinumab 300 mg 2 ml autoinjector (AI) from MATURE trial (NCT03589885). Eligible patients were randomized to secukinumab 300 mg 2 ml AI or 2× 1 ml prefilled syringe (PFS) or placebo. The co-primary endpoints were psoriasis area and severity index (PASI) 75 and investigator's global assessment (IGA) 0/1 response rates at Week 12 versus placebo. Other endpoints included PASI90/100 response, dermatology life quality index (DLQI) 0/1, PKs, 2 ml AI usability rated using self-injection assessment questionnaire (SIAQ), and safety. The study met both co-primary and secondary endpoints (p < 0.0001). Secukinumab 300 mg 2 ml AI and 2× 1 ml PFS treatments led to superior PASI75/90/100 (2 ml AI: 95.1%/75.6%/43.9%; 2× 1 mL PFS: 83.2%/62.6%/37.5% and placebo: 10%/5.0%/0.0%, respectively), IGA, and DLQI 0/1 responses compared with placebo, and efficacy was sustained through 52 weeks. SIAQ results showed high usability of self-injection with 2 mL AI device. No new safety signals were observed. Study design may bias the interpretation of safety profile after Week 12, due to different exposure of secukinumab versus placebo. Secukinumab 300 mg administered with the 2 mL AI demonstrated superior efficacy over placebo, good tolerability, and convenient administration.

Dramatic resolution of disseminated pyoderma gangrenosum associated with monoclonal gammopathy after therapy with bortezomib and dexamethasone.

Pyoderma gangrenosum (PG) is an uncommon inflammatory and ulcerative skin disorder, which is commonly associated with systemic conditions such as inflammatory bowel disease, arthritis and haematological malignancies. It is widely stated that control of the underlying diseases may lead to resolution of PG. However, standard of care dictates that patients suffering with monoclonal gammopathy of undetermined significance or smouldering multiple myeloma (MM) should not receive therapy unless they progress to symptomatic MM. Here, we report a woman in her 40s with a disseminated corticodependent PG, resistant to any treatment attempted, including anti-tumoral necrosis factor (TNF) therapy in which bortezomib-dexamethasone regimen results in dramatic healing of all lesions in only a month. This case supports the belief that treatment of the underlying monoclonal gammopathy could be necessary when PG presents as an aggressive, non-responding skin disease.
