The European Medicines Agency’s Committee for Medicinal Products for Human Use (CHMP) has recommended marketing authorization for a biosimilar rituximab product called Rixathon.
The recommended authorization for Rixathon encompasses all the same indications as the reference medicine, MabThera, which includes non-Hodgkin lymphoma (NHL), chronic lymphocytic leukemia (CLL), rheumatoid arthritis (RA), granulomatosis with polyangiitis (GPA), and microscopic polyangiitis (MPA).
The CHMP’s recommendation for Rixathon has been forwarded to the European Commission, which normally decides whether it will grant marketing authorization for a product within 67 days from the time the CHMP adopts its opinion.
The active substance of Rixathon is rituximab, a monoclonal antibody that binds specifically to the transmembrane protein CD20, which is found on both malignant and normal B cells.
In NHL and CLL, this promotes destruction of malignant B cells and controls tumor growth. In RA, GPA, and MPA, it reduces B cells involved in their pathogenesis.
The reference product for Rixathon is Mabthera, which was authorized for use in the European Union in June 1998.
The CHMP says studies have shown Rixathon to have comparable quality, safety, and efficacy to Mabthera.1, 2, 3
The applicant for Rixathon is Sandoz GmbH.
If authorized by the European Commission, Rixathon will be available for the following indications.
NHL
Rixathon is indicated for use in combination with chemotherapy to treat previously untreated patients with stage III-IV follicular lymphoma (FL).
Rixathon maintenance therapy is indicated for the treatment of FL patients responding to induction therapy.
Rixathon monotherapy is indicated for the treatment of patients with stage III-IV FL who are chemo-resistant or are in their second or subsequent relapse after chemotherapy.
Rixathon is indicated for use in combination with CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisolone) for the treatment of patients with CD20-positive diffuse large B-cell lymphoma.
CLL
Rixathon in combination with chemotherapy is indicated for the treatment of patients with previously untreated and relapsed/refractory CLL.
The CHMP noted that limited efficacy and safety data are available for patients previously treated with monoclonal antibodies, including rituximab, or patients who are refractory to previous rituximab plus chemotherapy.
RA, GPA, and MPA
Rixathon in combination with methotrexate is indicated for the treatment of adults with severe, active RA who have had an inadequate response to or cannot tolerate other disease-modifying anti-rheumatic drugs, including one or more tumor necrosis factor inhibitor therapies.
Rixathon in combination with glucocorticoids is indicated for the induction of remission in adults with severe, active GPA or MPA.
