Roche : Genentech : to Present New Clinical Data Across a Variety of Blood Diseases at American Society of Hematology 2015 Annual Meeting

Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), announced today that more than 45 abstracts featuring eight of its approved or investigational medicines will be presented during the 57th American Society of Hematology (ASH) Annual Meeting from December 5-8 in Orlando. The abstracts include more than 15 oral presentations across a broad range of molecular targets and combinations, as well as different clinical endpoints that Genentech is exploring in various blood diseases and lines of treatment.

“Our data at ASH this year showcase the evolution of our hematology portfolio and represent potential future approaches to helping people with blood cancers and blood disorders,” said Sandra Horning, M.D., chief medical officer and head of Global Product Development. “We’re particularly excited about studies evaluating new combinations with Gazyva and venetoclax, as well as studies examining the potential clinical significance of minimal residual disease negativity.”

Data for Gazyva include results from combination studies such as the Phase IIIb GREEN study and the pivotal CLL11 and GADOLIN studies. GREEN results will include data for Gazyva in combination with bendamustine in previously untreated chronic lymphocytic leukemia (CLL). Genentech will also share updated results from the Phase III CLL11 study, which formed the basis of the Gazyva approval in previously untreated CLL in combination with chlorambucil, and further data from the pivotal Phase III GADOLIN study for the investigational use of Gazyva in patients with indolent non-Hodgkin’s lymphoma (NHL) that is refractory to Rituxan^® (rituximab)-based treatment, that add to the positive results presented at the American Society of Clinical Oncology (ASCO) Annual Meeting in June this year.

Genentech will also present findings from multiple studies that suggest a potential role for minimal residual disease (MRD)-negativity in the treatment of certain blood cancers. In collaboration with AbbVie, Genentech will share new data for investigational medicine venetoclax as a monotherapy or in combinations across a number of blood cancers, including CLL, NHL, multiple myeloma (MM) and acute myeloid leukemia (AML). Data will also be shown for investigational medicine ACE910, which was recently granted breakthrough therapy designation by the U.S. Food and Drug Administration (FDA) for the prophylactic treatment of people who are 12 years or older with hemophilia A with factor VIII inhibitors.

Separately, the FDA has accepted for priority review the company's supplemental Biologics License Application (sBLA) for Gazyva in the treatment of patients with follicular lymphoma (FL) who relapsed after, or are refractory to a rituximab-containing regimen, based on GADOLIN study results. Marketing applications for Gazyva have also been submitted to other health authorities, including the European Medicines Agency, for approval consideration in the treatment of patients with FL who did not respond or who progressed during or up to six months after treatment with rituximab or a rituximab-containing regimen. In addition, AbbVie has submitted a New Drug Application (NDA) for venetoclax to the FDA under breakthrough therapy designation, based in part on results of the pivotal Phase II M13-982 study evaluating venetoclax in people with relapsed/refractory CLL harboring the 17p deletion. Genentech and AbbVie announced positive top-line results from this study earlier this year.

Gazyva Indication

Gazyva is a prescription medicine used with the chemotherapy drug, chlorambucil, to treat chronic lymphocytic leukemia (CLL) in adults who have not had previous CLL treatment.

Important Safety Information

Patients must tell their doctor right away about any side effects they experience. Gazyva can cause side effects that can become serious or life threatening, including:

Hepatitis B Virus (HBV): Hepatitis B can cause liver failure and death. If a patient has had history of hepatitis B infection, Gazyva could cause it to return. Patients should not receive Gazyva if they have active hepatitis B liver disease. The patient’s doctor or healthcare team will need to screen for hepatitis B before, and monitor the patient for hepatitis during and after, treatment with Gazyva. Sometimes this will require treatment for hepatitis B. Symptoms of hepatitis include: worsening of fatigue and yellow discoloration of skin or eyes.

Progressive Multifocal Leukoencephalopathy (PML): PML is a rare and serious brain infection caused by a virus. PML can be fatal. A patient’s weakened immune system could put the patient at risk. The patient’s doctor will watch for symptoms. Symptoms of PML include: confusion, difficulty talking or walking, dizziness or loss of balance, and vision problems.

Additional possible serious side effects of Gazyva:

Patients must tell their doctor right away about any side effects they experience. Gazyva can cause side effects that may become severe or life threatening, including:

• Infusion Reactions: These side effects may occur during or within 24 hours of any Gazyva infusion. Some infusion reactions can be serious, including, but not limited to, severe allergic reactions (anaphylaxis), acute life-threatening breathing problems, or other life-threatening infusion reactions. If a patient has a reaction, the infusion is either slowed or stopped until the patient’s symptoms are resolved. Most patients are able to complete infusions and receive medication again. However, if the infusion reaction is serious, the infusion of Gazyva will be permanently stopped. The patient’s healthcare team will take steps to help lessen any side effects the patient may have to the infusion process. The patient may be given medicines to take before each Gazyva treatment. Signs of infusion reactions may include: dizziness, nausea, chills, fever, vomiting, diarrhea, breathing problems, and chest pain.

• Tumor Lysis Syndrome (TLS): Gazyva works to break down cancer cells quickly. As cancer cells break apart, their contents are released into the blood. These contents may cause damage to organs and the heart, and may lead to kidney failure requiring the need for dialysis treatment. TLS, including death, has been reported in patients receiving Gazyva. The patient's doctor may prescribe medication to help prevent TLS. The patient's doctor will also conduct regular blood tests to check for TLS. Symptoms of TLS may include nausea, vomiting, diarrhea, and tiredness.

• Infections: While a patient is taking Gazyva, the patient may develop infections. Some of these infections may be severe. Fatal infections have been reported, so the patient should be sure to talk to the doctor if the patient thinks the patient has one. Patients with active infection should not be treated with Gazyva. Infections may continue even after the patient stops taking Gazyva. The patient's doctor may prescribe medications to help prevent infections. Symptoms of infection include fever and cough.
• Low White Blood Cell Count: When a patient has an abnormally low count of infection-fighting white blood cells, it is called neutropenia. While the patient is taking Gazyva, the patient's doctor will do blood work to check the patient's white blood cell counts. Neutropenia can develop during or after treatment with Gazyva. It may also last for more than one month. If a patient's white blood cell count is low, the patient's doctor may prescribe medication to help prevent infections.
• Low Platelet Count: Platelets help stop bleeding or blood loss. Gazyva may reduce the number of platelets the patient has in the blood. This may affect the clotting process. While the patient is taking Gazyva, the patient’s doctor will do blood work to check the patient’s platelet count.

Most common side effects of Gazyva

The most common side effects of Gazyva are infusion reactions, low white blood cell counts, low platelet counts, low red blood cell counts, fever, cough, nausea, and diarrhea.

Before receiving Gazyva, patients should talk to their doctor about:

Immunizations: Before receiving Gazyva therapy, the patient should tell the patient’s healthcare provider if the patient has recently received or is scheduled to receive a vaccine. Patients who are treated with Gazyva should not receive live vaccines.

Pregnancy: A patient should tell the doctor if the patient is pregnant, plans to become pregnant, or is breastfeeding. Gazyva may harm the unborn baby. Mothers who have been exposed to Gazyva during pregnancy should discuss the safety and timing of live virus vaccinations for their infants with their child’s healthcare providers. It is not known if Gazyva may pass into the patient’s breast milk. The patient should speak to the doctor about using Gazyva if the patient is breastfeeding.

Patients must tell their doctor about any side effects.

These are not all of the possible side effects of Gazyva. For more information, patients should ask their doctor or pharmacist.

Gazyva is available by prescription only.

Rituxan Indications

Rituxan (rituximab) is indicated for the treatment of patients with:

• Relapsed or refractory, low-grade or follicular, CD20-positive, B-cell NHL as a single agent
• Previously untreated follicular, CD20-positive, B-cell NHL in combination with first-line chemotherapy and, in patients achieving a complete or partial response to Rituxan in combination with chemotherapy, as single-agent maintenance therapy
• Non-progressing (including stable disease), low-grade, CD20-positive, B-cell NHL, as a single agent, after first-line CVP chemotherapy
• Previously untreated diffuse large B-cell, CD20-positive NHL in combination with CHOP or other anthracycline-based chemotherapy regimens
• Previously untreated and previously treated CD20-positive CLL in combination with fludarabine and cyclophosphamide (FC)

Rituxan is not recommended for use in patients with severe, active infections.

Important Safety Information:

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. Symptoms can include hives, rash, itching, facial or oral swelling, sudden cough, shortness of breath, difficulty breathing, weakness, dizziness, feeling faint, racing heart or chest pain.

• Severe Skin and Mouth Reactions: symptoms can include painful sores, ulcers, or blisters on the skin, lips or mouth; peeling skin; rash; or pustules.
• Hepatitis B Virus (HBV) Reactivation: may cause serious liver problems including liver failure and death. If patients have had hepatitis B or are carriers of HBV, receiving Rituxan could cause the virus to become an active infection again. Patient 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.
• Kidney Problems: the patient’s doctor should do blood tests to check how well the patient’s kidneys are working.
• Stomach and Serious Bowel Problems: can include blockage or tears in the bowel that can lead to death. Stomach area pain during treatment can be a symptom.
• Low Blood Cell Counts: the patient’s blood cell counts may be monitored during treatment.

The most common side effects of Rituxan are infusion reactions, chills, infections, body aches, tiredness and low white blood cells.

Patients must tell their doctor if they are pregnant, plan to become pregnant or are breastfeeding. It is not known if Rituxan may harm the patient’s unborn baby or pass into the patient’s breast milk. Women should use birth control while using Rituxan and for 12 months after treatment.

Patients must tell their doctor about any side effect that bothers them or that does not go away.

These are not all of the possible side effects of Rituxan. For more information, patients should ask their doctor or pharmacist.
