SILVER SPRING, Md.--(BUSINESS WIRE)--Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), today announced that the U.S. Food and Drug Administration’s (FDA) Oncologic Drugs Advisory Committee (ODAC) voted unanimously (11 to 0) that the benefit-risk of rituximab/hyaluronidase for subcutaneous (under the skin) injection was favorable for the treatment of certain blood cancers, which include: previously untreated follicular lymphoma, previously untreated diffuse large B-cell lymphoma (DLBCL), relapsed or refractory low grade or follicular lymphoma, and previously untreated and relapsed or refractory chronic lymphocytic leukemia (CLL). This new co-formulation includes the same monoclonal antibody as intravenous Rituxan® (rituximab) and hyaluronidase, a molecule that helps to deliver medicine under the skin. The FDA is expected to make a decision on approval by June 26, 2017.
“Subcutaneous rituximab can be administered in five to seven minutes compared to an hour and a half or more for intravenous Rituxan,” said Sandra Horning, M.D., chief medical officer and head of Global Product Development. “The significant reduction in administration time could especially benefit people with blood cancer who may receive years of treatment, and we are pleased the committee unanimously supported this new co-formulation.”
This co-formulation has been available in the European Union since 2014 where it is known as the subcutaneous (SC) formulation of MabThera® (rituximab) and is approved in approximately 50 other countries worldwide. In the United States, Rituxan is currently approved as an intravenous formulation for the treatment of people with previously untreated follicular lymphoma, previously untreated DLBCL, relapsed or refractory low grade or follicular lymphoma, and previously untreated and relapsed or refractory CLL. Intravenous Rituxan will continue to be available to patients if subcutaneous rituximab is approved. The committee’s vote does not affect intravenous Rituxan’s approved uses in the United States or in other countries.
The ODAC recommendation was based on a review of results from a clinical development program comprising five studies that together represented more than 2,000 people across key blood cancers for which intravenous Rituxan is approved. Because the monoclonal antibody in subcutaneous rituximab and intravenous Rituxan is the same, it was possible to utilize clinical studies that linked the safety and efficacy profile of the subcutaneous co-formulation to the well-established profile of intravenous Rituxan. The studies demonstrated that subcutaneous administration of the co-formulation resulted in non-inferior levels of rituximab in the blood (pharmacokinetics) and consistent clinical efficacy and safety outcomes compared to intravenous Rituxan. The clinical program also assessed patient preferences for subcutaneous rituximab and healthcare provider opinions. The studies were the following:
- SparkThera (NCT00930514): Phase Ib maintenance study in previously untreated or relapsed follicular lymphoma
- SABRINA (NCT01200758): Phase III induction and maintenance study in previously untreated follicular lymphoma
- SAWYER (NCT01292603): Phase Ib study in previously untreated CLL
- MabEase (NCT01649856): Phase III study in previously untreated DLBCL
- PrefMab (NCT01724021): Phase III patient preference study in previously untreated follicular lymphoma and DLBCL
Data from these studies were included in the company’s Biologics License Application for subcutaneous rituximab submitted to the FDA.
About Rituxan
Rituxan is a monoclonal antibody designed to attach to CD20, a protein found on certain types of B-cells. It is thought to work by attacking targeted cells together with the body's immune system. Rituxan was discovered by Biogen and is part of a collaboration between Genentech and Biogen in the United States. Since its initial approval in 1997, Rituxan has been used to treat more than 4.4 million people with blood cancers.
About Subcutaneous Rituximab
Subcutaneous rituximab is investigational in the United States. It is a co-formulation of the same monoclonal antibody as intravenous Rituxan and recombinant human hyaluronidase (rHuPH20), a technology licensed from Halozyme Therapeutics, Inc. Hyaluronidase is an FDA-approved molecule that facilitates the delivery of a relatively large volume of medicine under the skin. The subcutaneous co-formulation can be administered in five to seven minutes, compared to 1.5 to four hours for intravenous Rituxan.

Rituxan Indications
Rituxan® (rituximab) injection, for intravenous use, is indicated for the treatment of patients with:
- Low-grade or follicular CD20-positive non-Hodgkin’s lymphoma as a single-agent therapy in patients whose disease recurred or did not respond to initial treatment
- Follicular CD20-positive non-Hodgkin’s lymphoma as an initial treatment with chemotherapy, and in patients whose initial treatment was successful, as a single-agent follow-up therapy
- Low-grade CD20-positive non-Hodgkin’s lymphoma as a single-agent follow-up therapy for patients who did not progress on initial treatment with CVP chemotherapy
- CD20-positive diffuse large B-cell non-Hodgkin’s lymphoma as an initial treatment in combination with CHOP chemotherapy
- CD20-positive chronic lymphocytic leukemia in combination with FC chemotherapy as an initial treatment or as a treatment after disease has recurred
People with serious infections should not receive Rituxan.
It is not known if Rituxan is safe or effective in children.
Important Safety Information:
Patients must tell their doctor right away about any side effects they experience. Rituxan can cause serious side effects that can lead to death, including:
- Infusion Reactions: may occur during or within 24 hours of the infusion. The patient’s doctor should give the patient medicines before their treatment.

If patients have had hepatitis B or are carriers of HBV, receiving Rituxan could cause the virus to become an active infection again. Patients should not receive Rituxan if they have active HBV liver disease. The patient’s doctor will do blood tests to check for HBV infection prior to treatment and will monitor the patient during and for several months following their treatment.
- Progressive Multifocal Leukoencephalopathy (PML): a rare, serious brain infection that can lead to severe disability and death and for which there is no known prevention, treatment or cure. Symptoms can include difficulty thinking, loss of balance, changes in speech or walking, weakness on one side of the body or blurred or lost vision.
What are the additional possible serious side effects of Rituxan?
Patients must tell their doctor right away about any side effects they experience. Rituxan can cause serious side effects that can lead to death, including:
- Tumor Lysis Syndrome (TLS): may cause kidney failure and the need for dialysis treatment, abnormal heart rhythm and can lead to death. The patient’s doctor may give the patient medicines before their treatment to help prevent TLS.
- Serious Infections: can happen during and after treatment and can lead to death. These infections may be bacterial, fungal or viral. Symptoms can include fever; cold or flu symptoms; earache or headache; pain during urination; white patches in the mouth or throat; cuts or scrapes that are red, warm, swollen or painful.
- Heart Problems: symptoms can include chest pain and irregular heartbeats that may require treatment. The patient’s doctor may need to stop their treatment.
