FDA approves Roche’s MabThera/Rituxan (rituximab) for pemphigus vulgaris
- MabThera/Rituxan is the first FDA-approved treatment for moderate to severe pemphigus vulgaris (PV) in more than 60 years
- FDA previously granted Priority Review, Breakthrough Therapy Designation and Orphan Drug Designation to MabThera/Rituxan for the treatment of PV
- MabThera/Rituxan is now FDA-approved to treat four autoimmune diseases
Roche (SIX: RO, ROG; OTCQX: RHHBY) announced today that the US Food and Drug Administration (FDA) has approved MabThera/Rituxan® (rituximab) for the treatment of adults with moderate to severe pemphigus vulgaris (PV), a rare, serious, potentially life-threatening condition characterised by progressive painful blistering of the skin and mucous membranes.1
MabThera/Rituxan is the first biologic therapy approved by the FDA for PV and the first major advancement in the treatment of the disease in more than 60 years. The FDA previously granted Priority Review, Breakthrough Therapy Designation and Orphan Drug Designation to MabThera/Rituxan for the treatment of PV. With today’s FDA decision, MabThera/Rituxan is now approved to treat four autoimmune diseases.
“Today’s decision by the FDA provides the first approved treatment option in more than 60 years for patients with pemphigus vulgaris, a potentially life-threatening disease,” said Sandra Horning, MD, Chief Medical Officer and Head of Global Product Development. “We are pleased to offer Rituxan as a new and effective therapy to patients with this serious condition.”
The FDA approval is based on data from the Ritux 3 trial, a Roche-supported, randomised, controlled trial conducted in France which evaluated European Union-approved rituximab product (MabThera) plus a tapering regimen of oral corticosteroid (CS) treatment compared to a standard dose of CS alone as a first-line treatment in patients with newly diagnosed moderate to severe pemphigus. The primary endpoint of the study was complete remission at month 24 without the use of steroids for two or more months. Results of the study showed that 90 percent of PV patients treated with MabThera met the endpoint, compared to 28 percent of PV patients treated with CS alone. These results supported the efficacy of MabThera/Rituxan in treating adults with moderate to severe PV, while tapering off of CS therapy. These results were published in The Lancet in March 2017. 2
Recently an international panel of experts, the International Bullous Disease Consensus Group, provided new recommendations on the diagnosis and management of pemphigus in the Journal of the American Academy of Dermatology.3 Based on existing European treatment guidelines, a Delphi survey process was used to help achieve international expert consensus. The consensus includes the recommendation to use an anti-CD20 monoclonal antibody (MabThera/Rituxan) and corticosteroids as first line therapy options for moderate to severe pemphigus.
About pemphigus vulgaris
Pemphigus vulgaris is an autoimmune, intraepidermal, blistering disease affecting the skin and mucous membranes.1 It is the most common type of a group of autoimmune disorders collectively called pemphigus.4 It is estimated that around three in every 100,000 people are diagnosed with this disease.5
About the PEMPHIX study
Phase III, randomised, double-blind, double-dummy, active-comparator, parallel-arm multicentre study (PEMPHIX, NCT02383589) designed to evaluate the efficacy and safety of MabThera/Rituxan compared with mycophenolate mofetil (MMF) in patients with moderate to severe active pemphigus vulgaris requiring 60-120 mg/day oral prednisone (or equivalent).3
MabThera/Rituxan is approved to treat rheumatoid arthritis (RA) in combination with another prescription medicine called methotrexate, to reduce the signs and symptoms of moderate to severe active RA in adults, after treatment with at least one other medicine called a tumour necrosis factor (TNF) antagonist has been used and did not work well enough.
MabThera, in combination with glucocorticoids, is indicated for the induction of remission in adult patients with severe, active granulomatosis with polyangiitis (Wegener’s, GPA) and microscopic polyangiitis (MPA).
People with serious infections should not receive MabThera/Rituxan. It is not known if MabThera/Rituxan is safe or effective in children.
