NCT ID: NCT06213909 Recruiting - Bullous Pemphigoid Clinical Trials

Retrospective Study of the Effects of Sub-pathologic Phenotypes of BP on Clinical Management and Prognosis

BP
Start date: January 11, 2024
Phase:
Study type: Observational

Bullous pemphigoid (BP) is a chronic autoimmune subepidermal blistering disease primarily affecting the elderly with a significant risk of mortality and morbidity. Various inflammatory cells such as eosinophils, lymphocytes, neutrophils and their granulopoiesis play an important role in the pathogenesis of BP. Infiltration of peripheral blood eosinophils, lymphocytes, and neutrophils into the skin is considered a major feature of BP, making it a heterogeneous disease with different histologic and clinical subtypes. This clinical study was conducted to further investigate the impact of different pathologic phenotypes of BP on the treatment and prognosis of the disease. A retrospective epidemiologic investigative approach was used,and case collection included demographic information, medical history, clinical manifestations, and histopathologic features. Including gender, age, duration of disease, number of days of hospitalization, mucosal involvement, clinical diagnosis before admission, histopathological diagnosis, laboratory tests, concomitant diseases, treatment and its changes in laboratory indexes before and after treatment.

NCT ID: NCT06148090 Recruiting - Clinical trials for Adrenal Insufficiency

Screening for Adrenal Insufficiency During Dermocorticoid Reduction in Bullous Pemphigoid (BP)

PB-DEPIST
Start date: January 4, 2024
Phase: N/A
Study type: Interventional

The braking of the corticotropic axis is well established during the induction phase of superpotent topical corticosteroid therapy (clobetasol propionate) in bullous pemphigoid (BP). But the evolution of the corticotropic axis in the following months, especially during the tapering of topical steroids has never been studied. The objective of this study is to evaluate the prevalence of adrenal insufficiency during the topical corticosteroid therapy tapering in patients treated according to current recommendations. The secondary objectives of the study are : - to evaluate the presence of other clinico-biological signs of adrenal insufficiency (hypotension, hypoglycemia and/or hyponatremia) - to compare the characteristics of patients with adrenal insufficiency to those without in order to identify potential risk factors for adrenal insufficiency in BP.

NCT ID: NCT05984381 Recruiting - Bullous Pemphigoid Clinical Trials

Efficacy and Safety of add-on Dapsone Versus add-on Methotrexate in Patients With Bullous Pemphigoid

Start date: August 1, 2023
Phase: Phase 4
Study type: Interventional

Bullous pemphigoid (BP) is an autoimmune subepidermal blistering disorder most commonly affecting the older population between 60-80 years old. The characteristic feature of BP is itchy patches associated with blisters and erosions. BP significantly affects the patient's quality of life as it causes physical discomfort with itchy patches, blisters, and erosions. Several pieces of evidence from previous studies showed that the production of autoantibodies against the hemidesmosomal anchoring proteins BP180 (Bullous Pemphigoid antigen (BPAG 2)) and BP230 (BPAG 1) is the most common cause for bullous pemphigoid. Therapeutic latency, lack of efficacy in many patients, and adverse drug reactions are the primary concerns in the current bullous pemphigoid treatment paradigm, including high-dose steroid treatment. To overcome these treatment challenges, combination therapy with agents having a steroid-sparing effect like mycophenolate mofetil, cyclophosphamide, azathioprine, and Methotrexate are tested as an add-on to low-dose steroids. 8So other immunosuppressive agents with better safety profiles and more efficacy, like Dapsone and Methotrexate as an add-on to low-dose steroids, can be used. Investigator's literature search found no randomized controlled trial with Dapsone versus Methotrexate as an add-on to first-line steroid has been conducted to compare the efficacy and safety in bullous pemphigoid patients. So, a randomized controlled trial has been planned to evaluate the safety and efficacy of add-on methotrexate versus Dapsone in bullous pemphigoid patients.

NCT ID: NCT05954416 Recruiting - Clinical trials for Neurofibromatosis Type 1

FARD (RaDiCo Cohort) (RaDiCo-FARD)

FARD
Start date: March 7, 2018
Phase:
Study type: Observational

The goal of this observational study is to conduct a prospective assessment of the individual Burden of 9 rare skin diseases to assess disability in the broadest sense of the term (psychological, social, economic and physical) for patients and/or families. Two types of indicators will be used to reach this objective : 1. an individual burden score calculated based on a burden questionnaire created specifically, approved and designed to understand the tendency to changes in care and lifestyles. The burden questionnaire should be used by patients and/or their family themselves in self-assessment. 2. a descriptive analysis of all resources (medical and non-medical) used by the family unit to manage the disease.

NCT ID: NCT05681481 Recruiting - Bullous Pemphigoid Clinical Trials

A Phase 3 Study to Evaluate the Long-term Safety, Tolerability and Efficacy of Efgartigimod PH20 SC in Adult Participants With Bullous Pemphigoid

BALLAD+
Start date: March 22, 2023
Phase: Phase 3
Study type: Interventional

ARGX-113-2010 is an open-label extension study with the aim to provide supporting evidence that efgartigimod PH20 SC is a safe and effective long-term treatment for bullous pemphigoid (BP), providing symptom control and eventually remission, while also reducing the cumulative exposure to oral corticosteroids (OCS). All participants who complete the end-of-treatment period (EoTP) visit at week 36 in ARGX-113-2009 will be invited to enroll. In ARGX-113-2009, participants received efgartigimod PH20 SC or placebo with concurrent OCS, or rescue therapy (without efgartigimod PH20 SC or placebo). Depending on their clinical status at the time of rollover into ARGX-113-2010, participants may stop, continue or initiate efgartigimod PH20 SC treatment. In ARGX-113-2010, participants will stop efgartigimod PH20 SC treatment when they achieve complete remission (CR) or partial remission (PR) while being off other concurrent BP therapy for at least 8 weeks. Participants not in CR or PR while off OCS for ≥8 weeks and not on rescue therapy will either start or continue efgartigimod PH20 SC treatment, while maintaining the treatment allocation of ARGX-113-2009 blinded. Participants may also be retreated with efgartigimod PH20 SC after a relapse. In this study, loading doses of 2000 mg (on day 1 and day 8 of a treatment course) and weekly maintenance doses of 1000 mg will be used.

NCT ID: NCT05284929 Recruiting - Bullous Pemphigoid Clinical Trials

Human Leukocyte Antigen Class II (DRB1 and DQB1) Alleles and Haplotypes Frequencies in Patients With Pemphigus Vulgaris Among the Russian Population

Start date: May 17, 2017
Phase:
Study type: Observational

Pemphigus is a rare autoimmune life-threatening blistering condition affecting skin and mucous membranes. Pemphigus belongs to a family of polygenic disorders. Several different genes encoding molecules regulate pemphigus autoimmunity. Many trials focused on HLA investigation. Increased levels of certain HLA class II alleles frequencies in pemphigus have been reported in various populations. However, they were not investigated in the Russian population. The aim of our study is to investigate HLA class II alleles and haplotypes in Russian patients with pemphigus. Methods Patients and controls We are recruiting 120 patients with pemphigus. The diagnosis was based on clinical and histopathological findings and confirmed by immunofluorescent techniques (direct and indirect immunofluorescent tests). Before sampling, written consent was obtained from each subject. A single blood sample for HLA typing was obtained from all subjects. This study has been approved by the Ethics Committee of Sechenov University, Russia. Phenotypic and allelic frequencies were compared with healthy blood donors (n=100) registered in Sechenov University blood center.

NCT ID: NCT04641884 Recruiting - Immunotherapy Clinical Trials

Bullous Pemphigoid Induced by antiPD-1/PDL-1 Therapy

Start date: April 1, 2020
Phase:
Study type: Observational

Immune checkpoint inhibitors (monoclonal antibodies targeting cytotoxic T lymphocyte-associated antigen-4 (CTLA-4), programmed cell death protein 1 (PD-1) or programmed death ligand 1 (PD- L1)) have revolutionized the treatment of many cancers. The widespread use of these treatments has triggered a new spectrum of immune related adverse events (irAE). Several cases of bullous pemphigoid (BP) triggered by antiPD-1/PDL-1 therapy have been reported, and their characteristics are currently poorly described in the literature. The investigators sought to collect the French cases of BP triggered by antiPD-1/PDL-1 therapy, and to describe their clinical, biological and histological characteristics. In this national, retrospective, observational study, investigators included patients treated with antiPD-1/PDL-1 therapy, with a diagnosis of bullous pemphigoid occurring during treatment or up to 12 months after its discontinuation. Diagnosis of BP was made by the dermatologist and was based on the following criteria: compatible clinical presentation, compatible histopathology findings, positive direct immunofluorescence (DIF) studies, positive enzyme-linked immunosorbent assay BP180/enzyme-linked immunosorbent assay BP230.

NCT ID: NCT03926377 Recruiting - Osteoporosis Clinical Trials

Influence of Dermocorticoids on Bone Mineral Density in Patients With Bullous Pemphigoid

DERMOS
Start date: April 1, 2019
Phase: Phase 4
Study type: Interventional

Bullous pemphigoid is the most common type of bullous skin disease and is clinically characterized by clear-tense bullae, which result in post-bullous cutaneous erosions, altering the skin barrier. The treatment of this pathology consists of the application of high doses of topical corticosteroids (clobetasol propionate) for a prolonged period of at least 6 months. The main objective of this study is to demonstrate a change in bone mineral density at 6 months after initiation of treatment, in subjects with bullous pemphigoid and treated with topical corticosteroid.
