Filter by:ARGX-113-2009 is an operationally seamless 2-part, phase 2/3, prospective, global, multicenter, randomized, double-blinded, placebo-controlled study to investigate the efficacy, safety, tolerability, immunogenicity, participant-reported outcome measures (including those assessing participant QoL), PK, and PD of efgartigimod PH20 SC administered via subcutaneous (SC) injection in adult participants with moderate to severe BP. This study intends to demonstrate that efgartigimod is an effective and safe treatment for BP, providing participants with control of disease activity (CDA) and eventually remission while reducing their cumulative exposure to OCS. study will consist of 2 parts: - Part A of the study is a phase 2 evaluation that intends to provide proof of concept for the therapeutic activity of efgartigimod PH20 SC in participants with BP. - Part B of the study is a phase 3 evaluation that intends to confirm the results obtained from part A in a separate, larger group of participants with BP. An interim analysis will be performed during part A (on data obtained through week 26 for all Part A participants) to assess the primary endpoint and several secondary endpoints, confirm the appropriate sample size for part B of the study, and determine whether the efficacy results observed through week 26 of part A warrant continued study of efgartigimod PH20 SC for the treatment of participants with BP (futility analysis). Other than differences in main goals, endpoints, and statistical analyses, parts A and B are identical in schedule, structure, assessments, and conduct.
The investigators conducted a prospective study which included all patients diagnosed with biopsy-proven BP in the Dermatology Department of Attikon hospital between April 1, 2009 and December 31, 2019. 113 consecutive patients with BP were identified. The investigators included the patients with type 2 diabetes and investigated the percentage of patients who were under treatment with DPP4-is. The specific DPP4-i prescribed was also documented.Medical information including patients' age, sex, other comorbidities and concomitant medications were also recorded. Furthermore, the investigators evaluated the effect of different types of treatment (topical steroids, systemic corticosteroids, immunosuppressive agents) on bullous pemphigoid.
The primary objective of the study is to demonstrate that dupilumab is superior to placebo in achieving sustained remission off oral corticosteroids (OCS) in patients with bullous pemphigoid (BP). The secondary objectives of the study are: - To evaluate the OCS-sparing effects of dupilumab in patients with BP - To evaluate the effect of dupilumab on itch in patients with BP - To evaluate the effects of dupilumab on health-related quality of life measures in patients with BP - To evaluate the effect of dupilumab in circulating BP180 and BP230 autoantibody titers - To assess the safety and tolerability of dupilumab administered to patients with BP - To characterize the trough concentrations of functional dupilumab over time following administration of dupilumab in patients with BP - To assess the immunogenicity of dupilumab in patients with BP over time
The following is the investigators hypothesis regarding the pruritus of BP patients during remission. Anti-BP 180 IgE binds to dermal mast cells, inducing their activation and secretion of mediators after being cross-linked by antigens. Among mediators, histamine directly induces itching and vessel changes, whereas tryptase potentiates itching and vessel changes in an indirect way through the actions of neuropeptides. Tryptase stimulates neurons which in turn secrete neuropeptides.
