Healthcare Provider Experience in Diagnosing and Treating Cutaneous T-Cell Lymphoma.

INTRODUCTION: Cutaneous T-cell lymphoma (CTCL) is a rare, heterogeneous group of non-Hodgkin lymphomas characterized by various clinical, molecular, and histopathologic features of the skin. Variants of CTCL share many clinical features with common inflammatory skin diseases such as atopic dermatitis and psoriasis, making accurate and early diagnosis challenging in clinical settings. Inappropriate treatment or a delay in diagnosis can lead to increased morbidity and mortality. Here, we report findings from an online survey that investigated dermatology community practice, knowledge, and education surrounding CTCL. METHODS: An electronic survey of ten questions was developed and approved by physician experts in CTCL to assess experiences in diagnosing and treating CTCL among healthcare providers (HCPs). The survey was deployed to 10,600 US dermatology HCPs, including medical doctors (MDs), doctors of osteopathic medicine (DOs), nurse practitioners (NPs), and physician assistants (PAs) and excluding HCPs associated with CTCL centers of excellence. RESULTS: Among 44 HCPs who responded and were eligible for inclusion, 82% had diagnosed between one and ten CTCL cases in the last 5 years. Most respondents (91%) reported that they include CTCL in their differential diagnoses after patients do not respond to treatment of more common conditions. Patients with CTCL were frequently diagnosed with other inflammatory dermatoses-most commonly dermatitis and psoriasis-before a CTCL diagnosis, and many were treated with ineffective therapies for years. The most common length of time before a CTCL diagnosis was made was between 1 and 3 years, though 16% of HCPs reported that patients were treated for other diseases or skin conditions for ≥ 5 years. Two-thirds of HCPs agreed that further education surrounding CTCL is needed. CONCLUSIONS: Given the infrequency of CTCL and its similar presentation to other common dermatologic conditions, increased education of CTCL is needed in the dermatology community to improve patient outcomes.

Onset of Plaque Psoriasis Treatment Responses With Anti-IL-17/IL-23 Biologic Therapies.

BACKGROUND: The impact of psoriasis on quality of life arises from both physical symptoms, such as pain and pruritus, and the psychosocial effects of the often highly visible lesions. For patients with moderate-to-severe psoriasis seeking amelioration of these symptoms, time to onset of treatment response is an important consideration when determining an appropriate therapeutic approach with their healthcare provider. METHODS: In this review, we discuss the fluidity of the definition of rapid response and time-to-response expectations of patients with psoriasis receiving biologic therapies. Next, we focus on time to response of brodalumab, a human anti–interleukin-17 receptor A monoclonal antibody, in patients with moderate-to-severe psoriasis, as measured by the psoriasis area and severity index and the psoriasis symptom inventory. Brodalumab previously exhibited efficacy and safety in treatment of moderate-to-severe psoriasis in three phase 3 trials (AMAGINE-1/-2/-3), warranting further characterization of its ability to meet patient needs regarding rapidity of treatment response. Finally, we place time to response of brodalumab in the context of the current treatment landscape of biologic therapies for psoriasis (particularly those targeting the interleukin-17/interleukin-23 axis). RESULTS: Direct and indirect comparisons with other interleukin-targeting drugs support brodalumab’s more rapid onset of treatment effects, including skin clearance and relief of itch and pain. CONCLUSION: Brodalumab induces a rapid treatment response in patients with moderate-to-severe psoriasis and may promote earlier improvements in quality of life.

Two-Year US Pharmacovigilance Report on Brodalumab.

INTRODUCTION: Brodalumab is a human interleukin-17 receptor A antagonist indicated for the treatment of moderate-to-severe plaque psoriasis in adult patients who are candidates for systemic therapy or phototherapy and have failed to respond or have lost response to other systemic therapies. In the United States, brodalumab carries a boxed warning about suicidal ideation and behavior; however, no causal association was established between brodalumab and suicides reported during pivotal trials. We have previously reported results from an analysis of 1-year pharmacovigilance data in patients in the United States who took brodalumab, in which the most commonly reported adverse event was psoriasis flare. There were no completed suicides, suicide attempts, or serious fungal infections. Here, we provide a 2-year US pharmacovigilance report. METHODS: This analysis summarizes pharmacovigilance data reported to Ortho Dermatologics by US patients and healthcare providers from August 15, 2017, through August 14, 2019. The most common adverse events listed in the brodalumab package insert (incidence ≥ 1%; arthralgia, headache, fatigue, diarrhea, oropharyngeal pain, nausea, myalgia, injection-site reactions, influenza, neutropenia, and tinea infections) and adverse events of special interest are reported. RESULTS: Data were collected from 2677 patients in the United States who took brodalumab, with an estimated exposure of 1656 patient-years. Arthralgia was the most commonly reported adverse event (73 events; 0.04 events per patient-year). No suicide attempts or completed suicides were reported; there were 25 reports of depression. There were 46 serious infections and no serious fungal infections. One event of Crohn's disease was reported, which led to discontinuation. There were 13 malignancies, with none deemed related to brodalumab. CONCLUSIONS: This pharmacovigilance report supports the safety profile of brodalumab previously reported from long-term analyses of clinical trials and 1-year pharmacovigilance data.
