Efficacy and Safety of Rituximab Combined With Omalizumab in Patients With Bullous Pemphigoid

2019-10-21 12:45:28 | BioPortfolio


To evaluate the efficacy of rituximab combined with omalizumab in achieving sustained complete remission, evaluated by Bullous Pemphigoid Disease Area Index (BPDAI) in patients with bullous pemphigoid (BP) at Week 24 in patients with active moderate-to-severe BP refractory to rituximab therapy alone.


This is an open-label, noncontrolled, single center prospective study to evaluate the efficacy and safety of rituximab combined with omalizumab in patients with active moderate-to-severe BP refractory to rituximab treatment alone. Patients must have a confirmed diagnosis of BP and evidence of refractory disease after initiation of rituximab treatment at least 8 weeks prior.

Refractory disease will be defined as a failure of therapy (development of new non-transient lesions or continued extension of old lesions, or failure of established lesions to begin to heal or continued pruritus) or evidence of a relapse/flare (Appearance of ≥3 new lesions/month (blisters, eczematous lesions, or urticarial plaques) or at least one large (>10 cm diameter) eczematous lesion or urticarial plaques that do not heal within 1 week, or extension of established lesions or daily pruritus in patient who have achieved disease control) based on the outcome measures defined for BP from an international panel of experts.41

This study will be conducted at the University of California, Davis Department of Dermatology's investigational site.

The study will consist of 3 periods: a screening period, 24-week treatment period, and a 28-week follow-up period. During the treatment period, patient visits will be monthly. After the primary endpoint at Week 24, follow up assessments will be scheduled every 3 months.

Rituximab 1000 mg will be administered by IV infusion 6 months after the patient's initial cycle of rituximab (received in the screening period). In order to reduce the frequency and severity of infusion-related reactions, all patients will be pre-medicated per the infusion center's therapy beacon protocol. Omalizumab (300 mg) will be administered subcutaneously every 2 weeks starting on Day 1.

All patients will be provided topical clobetasol 0.05% ointment or equivalent strength potency topical corticosteroid. Topical steroid application will be used 40 grams twice daily as needed for itch.

Patients can be discontinued from study treatment at any time during the study. Patients who withdraw from the treatment period will return to the clinic for an early withdrawal visit. After the withdrawal visit, the patient will be asked to enter the follow up period of the study.

From Week 1 through Week 52, patients who do not experience 50% improvement in their BPDAI at week 16 are eligible to receive rescue therapy with prednisone, another immunosuppressive medication (e.g. cellcept), IV Ig, or another treatment or procedure as per the investigator's best medical judgment. Patients who receive rescue therapy will be withdrawn from the study.

Medical and Biotech [MESH] Definitions

An itching, autoimmune, bullous SKIN disease that occurs during the last two trimesters of PREGNANCY and PUERPERIUM. It also affects non-pregnant females with tissue of PLACENTA origin, such as CHORIOCARCINOMA; or HYDATIDIFORM MOLE. It exhibits antigenic and clinical similarity to bullous pemphigoid (PEMPHIGOID, BULLOUS). This disease does not involve herpes viruses (old name, herpes gestationis).

A chronic and relatively benign subepidermal blistering disease usually of the elderly and without histopathologic acantholysis.

A chronic blistering disease with predilection for mucous membranes and less frequently the skin, and with a tendency to scarring. It is sometimes called ocular pemphigoid because of conjunctival mucous membrane involvement.

Designation for several severe forms of ichthyosis, present at birth, that are characterized by hyperkeratotic scaling. Infants may be born encased in a collodion membrane which begins shedding within 24 hours. This is followed in about two weeks by persistent generalized scaling. The forms include bullous (HYPERKERATOSIS, EPIDERMOLYTIC), non-bullous (ICHTHYOSIS, LAMELLAR), wet type, and dry type.

Group of rare congenital disorders characterized by impairment of both humoral and cell-mediated immunity, leukopenia, and low or absent antibody levels. It is inherited as an X-linked or autosomal recessive defect. Mutations occurring in many different genes cause human Severe Combined Immunodeficiency (SCID).
