Introduction
Psoriatic disease is associated with considerable impairment of quality of life (QoL). The PROSE study (NCT02752776) investigated the impact of secukinumab treatment on patient‐reported outcomes (PRO) in patients with moderate to severe psoriasis stratified by their treatment history.
Methods
PROSE was a prospective, non‐randomised, multicentre study. Patients were categorized at baseline according to treatment history as naïve [naïve to any systemic therapy (N = 663)], conventional systemic [previously exposed to ≥1 conventional systemic (CS) therapy (N = 673)] and biologics [previously exposed to ≥1 biologic therapy (N = 324)]. QoL PROs, efficacy and safety of secukinumab 300 mg were assessed for a period of 52 weeks.
Results
The primary objective was met with 70.8% patients achieving a Dermatology Life Quality Index (DLQI) 0/1 response at Week 16 (naϊve, 74.7%; CS, 71.3%; biologic, 61.7%), with effects sustained up to Week 52. Mean Family DLQI (FDLQI) score decreased from 11.5 at baseline (naϊve, 11.3; CS, 11.4; biologic, 12.1) to 2.5 at Week 16 (naϊve, 2.5; CS, 2.3; biologic: 3.5). Substantial improvements in EuroQoL 5‐Dimension Health Questionnaire, Numeric Rating Scale for pain, itching and scaling, Health Assessment Questionnaire‐Disability Index, Treatment Satisfaction Questionnaire for Medication, and Patient Benefit Index were also observed at Week 16. The QoL gains were associated with substantial improvements in Psoriasis Area and Severity Index and Investigator Global Assessment mod 2011 0/1 response. No meaningful difference was observed in the efficacy or QoL improvements across patient subpopulations. All QoL and efficacy parameter improvements were sustained up to Week 52. Secukinumab treatment was well‐tolerated, and no new safety signals were observed.
Conclusion
Secukinumab treatment resulted in complete normalization of QoL in a substantial proportion of psoriasis patients, and their families, regardless of their prior treatment history.
Introduction Psoriatic disease is associated with considerable impairment of Quality of Life (QoL). The PROSE study (NCT02752776) examined the impact of secukinumab on patient-reported outcomes in patients with moderate-to-severe psoriasis (PsO) stratified by previous exposure to systemic treatment. Methods In this prospective, non-randomized, multicentre study, patients were categorized at baseline according to previous exposure to systemic treatment: na€ ıve [na€ ıve to any systemic treatment (N = 663)], conventional systemic [previously exposed to ≥1 conventional systemic therapy (N = 673)] and biologics [previously exposed to ≥1 biologic (N = 324)]. Baseline demographics including age, gender, race, body weight and body mass index, disease characteristics and patient-reported QoL outcomes [Dermatology Life Quality Index (DLQI), Family DLQI (F-DLQI)] of patients enrolled in the study are reported here. Results Baseline demographic characteristics were well balanced across the three subpopulations. Na€ ıve patients had a shorter time since diagnosis (15.5 AE 12.1 years) compared with the conventional systemic (19.1 AE 12.5 years) and biologic patients (23.0 AE 12.5 years), and lower rates of psoriatic arthritis (6.6% vs. 17.4% and 27.8%, respectively). Metabolic syndrome (37.6-43.5%), obesity (16.9-19.1%), hyperlipidaemia (15.3-21.9%) and diabetes mellitus (6.8-14.2%) were reported at numerically higher rate in the biologic group. The mean PASI (19.7 AE 7.9), affected Body Surface Area (28.2 AE 15.3%) as well as the Investigator Global Assessment score (patients with score 4: 33.7%) indicated severe disease at baseline and were comparable for the three groups. QoL impairment was evident from mean DLQI
MCC is a rare but highly aggressive skin cancer. The identification of the driving role of Merkel cell polyomavirus (MCPyV) and ultraviolet-induced DNA damage in the oncogenesis of MCC allowed a better understanding of its biological behavior. The presence of MCPyV-specific T cells and lymphocytes exhibiting an ‘exhausted’ phenotype in the tumor microenvironment along with the high prevalence of immunosuppression among affected patients are strong indicators of the immunogenic properties of MCC. The use of immunotherapy has revolutionized the management of patients with advanced MCC with anti-PD-1/PD L1 blockade, providing objective responses in as much as 50–70% of cases when used in first-line treatment. However, acquired resistance or contraindication to immune checkpoint inhibitors can be an issue for a non-negligible number of patients and novel therapeutic strategies are warranted. This review will focus on current management guidelines for MCC and future therapeutic perspectives for advanced disease with an emphasis on molecular pathways, targeted therapies, and immune-based strategies. These new therapies alone or in combination with anti-PD-1/PD-L1 inhibitors could enhance immune responses against tumor cells and overcome acquired resistance to immunotherapy.
