South San Francisco, CA -- March 23, 2017 --
Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), today announced that the U.S. Food and Drug Administration (FDA) has granted Breakthrough Therapy Designation status to Rituxan® (rituximab) for pemphigus vulgaris, a rare, serious and life-threatening condition characterized by progressive painful blistering of the skin and mucous membranes.2 FDA Breakthrough Therapy Designation is intended to expedite the development and review of medicines with early evidence of potential clinical benefit in serious diseases and to help ensure that patients receive access to medicines as soon as possible. Genentech is currently enrolling a Phase III study in pemphigus vulgaris (PEMPHIX, NCT02383589), a disease for which there are limited treatment options. 1
“People with pemphigus vulgaris need more options and we look forward to working with the FDA to make Rituxan available to patients with this potentially deadly disease,” said Sandra Horning, M.D., chief medical officer and head of Global Product Development. “We are committed to developing therapies that target B cells in areas of unmet need across a range of immune and malignant diseases, including new antibody constructs that enhance efficacy, safety or both.”
This is the fifteenth Breakthrough Therapy Designation granted to Genentech medicines since 2013.
Breakthrough Therapy Designation status was granted based on data from a Roche-supported randomized trial conducted in France, which evaluated Rituxan plus oral corticosteroid (CS) treatment compared to CS as a first-line treatment in patients with moderate to severe pemphigus. 3 Results of the study, published in The Lancet, show that Rituxan may provide substantial improvement in pemphigus vulgaris remission rates and successful tapering and/or cessation of CS therapy. 3
In 2015, the FDA granted Orphan Drug Designation to Rituxan for the treatment of pemphigus vulgaris.
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. 2 It is estimated that around three in every 100,000 people are diagnosed with this disease.4
About the PEMPHIX study
Genentech initiated a Phase III, randomized, double-blind, double-dummy, active-comparator, parallel-arm multicenter study (PEMPHIX, NCT02383589) to evaluate the efficacy and safety of Rituxan compared with mycophenolate mofetil (MMF) in patients with moderate to severe active pemphigus vulgaris requiring 60-120 mg/day oral prednisone (or equivalent).5
What does Rituxan treat?
Rheumatoid arthritis (RA): 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 tumor necrosis factor (TNF) antagonist has been used and did not work well enough.
Granulomatosis with Polyangiitis (GPA) (Wegener’s Granulomatosis) and Microscopic Polyangiitis (MPA): with glucocorticoids, to treat GPA and MPA.
People with serious infections should not receive Rituxan. It is not known if Rituxan is safe or effective in children.
