Clinical determinants of clinical response to Sonidegib in advanced basal cell carcinoma: a monocenter experience.

OBJECTIVE: The purpose of this study is to evaluate the clinical determinants of complete response in locally advanced basal cell carcinoma (laBCC) patients receiving Sonidegib in a real-life, retrospective, observational study.  Hedgehog pathway inhibitors (Vismodegib and Sonidegib) are approved for the systemic treatment of locally advanced basal cell carcinoma (laBCC). The objective response rate was the primary endpoint of the trials for both drugs. PATIENTS AND METHODS: Adult patients with laBCC treated with Sonidegib at the Dermato-Oncology Unit of IFO San Gallicano between June 2020 and September 2022 were included in the study. Patient, tumor, and treatment characteristics were recorded. The complete response rate was the primary outcome. The median time to the best response and complete response were the secondary outcomes. Treatment-related adverse events (TRAEs) and dose adjustments were recorded. RESULTS: Of the 19 patients included in the study, eight (42.1%) achieved a complete response, seven (36.8%) had a partial response, and four experienced progressive disease (21%). The median time to the best response was 3 months in the group of patients with partial response (range 2.0-4.0, with three patients not evaluable) and 3.5 months in the group of patients with complete response (range 2-5). TRAEs occurred in 14 (73.6%) patients, with 8 (57.1%) reporting ≤2 TRAE categories and 6 (42.8%) >2. A total of 78.9% of patients received a modified treatment schedule; 12.5% of patients who achieved a complete response received full dosage from the beginning to the end of treatment, compared with 27.3% of those with a partial response. CONCLUSIONS: The associations between the clinical outcome of interest (objective response rate) and the clinicopathological and treatment characteristics were evaluated. No statistically significant association was observed. Our analysis confirms the observation that no statistically significant correlation exists between clinical response and Sonidegib alternate dose regimen.

Pharmacogenetics of psoriasis: HLA-Cw6 but not LCE3B/3C deletion nor TNFAIP3 polymorphism predisposes to clinical response to interleukin 12/23 blocker ustekinumab.

BACKGROUND: Our understanding of the genetic basis of predisposition to psoriasis is increasing exponentially due to the progress of genetic studies. However, so far little is known about genetic predisposition in relation to the response to psoriasis treatments. Recent data identified genetic predictors for the clinical outcome of conventional treatments such as methotrexate, acitretin and vitamin D derivatives, but few studies are available on genetic predictors of response to biologics. We hypothesized that genetic variations associated with increased risk of developing psoriasis may also act as predictors for the outcome of biologic therapy. OBJECTIVES: The aim of our study was to analyse the presence of three different psoriasis susceptibility genetic variations (HLA-Cw6; TNFAIP3 rs610604 polymorphism; LCE3B/3C gene deletions) in a cohort of patients affected by moderate to severe psoriasis under ustekinumab treatment. Our primary endpoint was to evaluate the association between Psoriasis Area and Severity Index (PASI) 75 response at week 12 and HLA-Cw6 status. METHODS: Fifty-one patients were genotyped by standard methods and psoriasis severity (PASI score) was evaluated at day 0 and after 4, 12, 24 and 40 weeks of treatment. RESULTS: We observed increased response to ustekinumab in Cw6-positive (Cw6POS) patients [PASI 75 at week 12: 96·4% in Cw6POS vs. 65·2% in Cw6-negative (Cw6NEG) patients; P = 0·008]. In addition, we show that HLA-Cw6POS patients responded faster to ustekinumab, 89·3% of them reaching PASI 50 at week 4, after a single injection (vs. 60·9% of HLA-Cw6NEG patients). The superior response of HLA-Cw6POS patients was maintained throughout the study period, reaching the highest statistical significance for PASI 75 at week 28 (96·35% Cw6POS vs. 72·7% Cw6NEG; odds ratio 9·8). Analysis of TNFAIP3 rs610604 polymorphism and LCE3B/3C gene deletions did not show any significant association with response to ustekinumab. CONCLUSIONS: Our observations underline the role of HLA-Cw6 not only as a psoriasis susceptibility gene, but also as a pharmacogenetic marker of response to ustekinumab in psoriasis.

Patients with moderate to severe plaque psoriasis: one year after the European Medicines Agency recommendation of efalizumab suspension.

BACKGROUND: In February 19, 2009, the European Medicines Agency (EMA) had recommended the suspension of the marketing authorization for efalizumab after the occurrence of cases of progressive multifocal leukoencephalopathy. OBJECTIVE: To explore the efficacy of alternative therapies for psoriasis and the health status of patients who discontinued efalizumab. METHODS: An observational study was performed on 101 patients. After the EMA communication, efalizumab was discontinued in the following 2-3 months. In agreement with the patients, we decided to either prescribe other treatments or none at all. RESULTS: After 1 year, 11 patients are still not treated, 63 patients are treated with biologics, and 9 patients are treated with systemic conventional therapies. CONCLUSION: In order to prevent rebound or relapse, various approaches are available, including cyclosporine, methotrexate and biologic therapies. Interestingly, in 11 out of 31 patients who did not receive any systemic drug, psoriasis is still under control, suggesting a long-term effect of efalizumab.

Efficacy of efalizumab in psoriasis patients previously treated with tumour necrosis factor blockers.

BACKGROUND: Biological therapy for moderate to severe psoriasis includes tumour necrosis factor (TNF) blockers (infliximab, etanercept and adalimumab) and T-cell-targeting agents (efalizumab, alefacept) that act in different steps of a common pathogenic pathway. Large amounts of data coming from clinical trials indicate each of these drugs as highly effective and safe. However, little is known about the efficacy of a second biological therapy after the failure of the first. OBJECTIVE: To evaluate whether the response to efalizumab in psoriasis patients was influenced by previous treatment with other biological agents. PATIENTS AND METHODS: We have retrospectively analyzed a group of 155 psoriasis patients treated with efalizumab during the last 5 years and determined its efficacy in patients previously treated with anti-TNF drugs comparing it with the efficacy and safety observed in patients previously treated with traditional systemic drugs instead. RESULTS: Efalizumab was shown to be as efficacious and safe in patients previously treated with biological agents as in those previously treated with traditional systemic drugs. Although not statistically significant, we observed a higher rate of response to efalizumab in patients previously treated with anti-TNF-alpha. PASI 75 was achieved at week 24 in 76.2% of the patients previously treated with biological agents versus 54.4% in patients previously treated with traditional drugs (OR = 2.9). CONCLUSIONS: These data suggest that efalizumab can be successfully used in psoriasis patients when TNF blockers cannot efficiently control the disease due to lack or loss of response, or when they have to be interrupted for intolerance or adverse events.

A biological approach in a patient with psoriasis and bullous pemphigoid associated with losartan therapy.

Several cases of psoriasis associated with bullous disorders have been reported, and it is clearly recognized that bullous pemphigoid (BP) is the most common bullous disorder observed in association with psoriasis, especially after ultraviolet (UV)B and psoralen UVA therapy. Moreover, other medications have been repeatedly reported to induce bullous diseases, especially pemphigus vulgaris. We report for the first time a case of BP possibly induced by losartan, an angiotensin II antagonist, in a patient with a severe psoriatic background. Angiotensin II type 1 receptor antagonists belong to a new class of drug for hypertension or congestive heart failure with established efficacy and few side-effects. Coexistence of psoriasis vulgaris with bullous diseases represents also a difficult therapeutic challenge. This rare case of psoriasis and generalized BP triggered by a sartan drug was treated with rituximab and etanercept.
