Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), today announced the submission of a supplemental New Drug Application to the U.S. Food and Drug Administration (FDA) for Venclexta (venetoclax) in combination with Gazyva (obinutuzumab) in people with previously untreated chronic lymphocytic leukemia (CLL) and co-existing medical conditions. The FDA is reviewing the application under the Real-Time Oncology Review pilot program, which aims to explore a more efficient review process to ensure safe and effective treatments are available to patients as early as possible.
More than 20,000 people will be diagnosed with untreated chronic lymphocytic leukemia in the United States this year, and many are ineligible for intensive chemotherapy-based options, said Sandra Horning, M.D., chief medical officer and head of Global Product Development. We are encouraged that this chemotherapy-free, fixed-duration combination is being reviewed under the FDAs Real-Time Oncology Review pilot program, and we are working closely with the agency to bring this new option to people with previously untreated chronic lymphocytic leukemia as quickly as possible.
Breakthrough Therapy Designation was granted based on results of the randomized Phase III CLL14 study, evaluating the fixed-duration combination of Venclexta plus Gazyva, compared to Gazyva plus chlorambucil, in people with previously untreated CLL and co-existing medical conditions. The study met its primary endpoint and showed a statistically significant reduction in the risk of disease worsening or death (progression-free survival [PFS] as assessed by investigator) compared to standard-of-care Gazyva plus chlorambucil. Safety for the Venclexta plus Gazyva combination appeared consistent with the known safety profiles of the individual medicines, and no new safety signals were identified with the combination. Data from the CLL14 study will be presented at an upcoming medical meeting. The CLL14 study is being conducted in cooperation with the German CLL Study Group (GCLLSG), headed by Michael Hallek, M.D., University of Cologne.
Venclexta is being developed by AbbVie and Genentech, a member of the Roche Group. It is jointly commercialized by the companies in the United States and commercialized by AbbVie outside of the United States.
About the CLL14 Study
CLL14 (NCT02242942) is a randomized Phase III study evaluating the combination of fixed-duration Venclexta plus Gazyva compared to Gazyva plus chlorambucil in patients with previously untreated chronic lymphocytic leukemia (CLL) and co-existing medical conditions. 432 patients with previously untreated CLL were randomly assigned to receive either a 12-month duration of Venclexta alongside six-month duration of Gazyva (Arm A) or six-month duration of Gazyva plus chlorambucil followed by an additional six-month duration of chlorambucil (Arm B). The primary endpoint of the study is investigator-assessed progression-free survival (PFS). Secondary endpoints include PFS assessed by independent review committee (IRC), minimal residual disease (MRD) status, overall response (OR), complete response (with or without complete blood count recovery, CR/CRi), overall survival (OS), duration of response, event-free survival, time to next CLL treatment and safety. The CLL14 study is being conducted in cooperation with the German CLL Study Group (GCLLSG), headed by Michael Hallek, M.D., University of Cologne.
Chronic lymphocytic leukemia (CLL) is the most common type of adult leukemia. In the United States, it is estimated that more than 20,000 new cases of CLL will be diagnosed in 2019. Although signs of CLL may disappear for a period of time after initial treatment, the disease is considered incurable and many people will require additional treatment due to the return of cancerous cells.
Venclexta is a first-in-class targeted medicine designed to selectively bind and inhibit the B-cell lymphoma-2 (BCL-2) protein. In some blood cancers and other tumors, BCL-2 builds up and prevents cancer cells from dying or self-destructing, a process called apoptosis. Venclexta blocks the BCL-2 protein and works to restore the process of apoptosis.
Venclexta is being developed by AbbVie and Genentech, a member of the Roche Group. It is jointly commercialized by the companies in the United States and commercialized by AbbVie outside of the United States. Together, the companies are committed to research with Venclexta, which is currently being studied in clinical trials across several types of blood and other cancers.
In the United States, Venclexta has been granted five Breakthrough Therapy Designations by the U.S. Food and Drug Administration (FDA): in combination with Gazyva for people with previously untreated chronic lymphocytic leukaemia (CLL) and co-existing medical conditions; in combination with Rituxan for people with relapsed or refractory CLL; as a monotherapy for people with relapsed or refractory CLL with 17p deletion; in combination with hypomethylating agents (azacitidine or decitabine) for people with untreated acute myeloid leukemia (AML) ineligible for intensive chemotherapy; and in combination with low-dose cytarabine for people with untreated AML ineligible for intensive chemotherapy.
Gazyva is an engineered monoclonal antibody designed to attach to CD20, a protein found only on certain types of B-cells. It is thought to work by attacking targeted cells both directly and together with the body’s immune system. Gazyva was discovered by Roche Glycart AG, a wholly owned, independent research unit of Roche. In the United States, Gazyva is part of a collaboration between Genentech and Biogen.
Combination studies investigating Gazyva with other approved or investigational medicines, including cancer immunotherapies and small molecule inhibitors, are underway across a range of blood cancers.
Venclextais a prescription medicine used:
- To treat adults with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL), with or without 17p deletion, who have received at least 1 prior treatment.
- In combination with azacitidine, or decitabine, or low-dose cytarabine to treat adults with newly-diagnosed acute myeloid leukemia (AML) who: ’ Are 75 years of age or older, or ’ Have other medical conditions that prevent the use of standard chemotherapy.
It is not known if Venclexta is safe and effective in children.
Important Safety Information
Venclexta can cause serious side effects, including:
Tumor lysis syndrome (TLS). TLS is caused by the fast breakdown of cancer cells. TLS can cause kidney failure, the need for dialysis treatment, and may lead to death. The patients doctor will do tests to check their risk of getting TLS before they start taking Venclexta. The patient will receive other medicines before starting and during treatment with Venclexta to help reduce the risk of TLS. The patient may also need to receive intravenous (IV) fluids through their vein.
The patients doctor will do blood tests to check for TLS when the patient first starts treatment and during treatment with Venclexta. It is important for patients to keep appointments for blood tests. Patients should tell their doctor right away if they have any symptoms of TLS during treatment with Venclexta, including fever, chills, nausea, vomiting, confusion, shortness of breath, seizures, irregular heartbeat, dark or cloudy urine, unusual tiredness, or muscle or joint pain.
Patients should drink plenty of water during treatment with Venclexta to help reduce the risk of getting TLS.
Patients should drink 6 to 8 glasses (about 56 ounces total) of water each day, starting 2 days before the first dose, on the day of the first dose of Venclexta, and each time a dose is increased.
The patients doctor may delay, decrease the dose, or stop treatment with Venclexta if the patient has side effects.
Certain medicines must not be taken when the patient first starts taking Venclexta and while the dose is being slowly increased because of the risk of increased tumor lysis syndrome.
- Patients must tell their doctor about all the medicines they take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. Venclexta and other medicines may affect each other, causing serious side effects.
- Patients must not start new medicines during treatment with Venclexta without first talking with their doctor.
Before taking Venclexta, patients must tell their doctor about all of their medical conditions, including if they:
- Have kidney problems.
- Have problems with body salts or electrolytes, such as potassium, phosphorus, or calcium.
- Have a history of high uric acid levels in the blood or gout.
- Are scheduled to receive a vaccine. The patient should not receive a live vaccine before, during, or after treatment with Venclexta, until the patients doctor tells them it is okay. If the patient is not sure about the type of immunization or vaccine, the patient should ask their doctor. These vaccines may not be safe or may not work as well during treatment with Venclexta.
- Are pregnant or plan to become pregnant. Venclexta may harm an unborn baby. If the patient is able to become pregnant, the patients doctor should do a pregnancy test before the patient starts treatment with Venclexta, and the patient should use effective birth control during treatment and for at least 30 days after the last dose of Venclexta. If the patient becomes pregnant or thinks they are pregnant, the patient should tell their doctor right away.
- Are breastfeeding or plan to breastfeed. It is not known if Venclexta passes into the patients breast milk. Patients should not breastfeed during treatment with Venclexta.
What to avoid while taking Venclexta:
Patients should not drink grapefruit juice, eat grapefruit, Seville oranges (often used in marmalades), or starfruit while they are taking Venclexta. These products may increase the amount of Venclexta in the patients blood.
Venclexta can cause serious side effects, including:
- Low white blood cell counts (neutropenia). Low white blood cell counts are common with Venclexta, but can also be severe. The patients doctor will do blood tests to check their blood counts during treatment with Venclexta. Patients should tell their doctor right away if they have a fever or any signs of an infection during treatment with Venclexta.
The most common side effects of Venclexta when used in combination with rituximab in people with CLL include low white blood cell counts; diarrhea; upper respiratory tract infection; cough; tiredness; and nausea.
The most common side effects of Venclexta when used alone in people with CLL/SLL include low white blood cell counts; diarrhea; nausea; upper respiratory tract infection; low red blood cell counts; tiredness; low platelet counts; muscle and joint pain; swelling of arms, legs, hands, and feet; and cough.
The most common side effects of Venclexta in combination with azacitidine, or decitabine, or low-dose cytarabine in people with AML include low white blood cell counts; nausea; diarrhea; low platelet counts; constipation; fever with low white blood cell counts; low red blood cell counts; infection in blood; rash; dizziness; low blood pressure; fever; swelling of arms, legs, hands, and feet; vomiting; tiredness; shortness of breath; bleeding; infection in lung; stomach (abdominal) pain; pain in muscles or back; cough; and sore throat.
Venclexta may cause fertility problems in males. This may affect the ability to father a child. Patients should talk to their doctor if they have concerns about fertility.
These are not all the possible side effects of Venclexta. Patients should tell their doctor about any side effect that bothers them or that does not go away.

Gazyva (obinutuzumab) 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.
- With the chemotherapy drug, bendamustine, followed by Gazyva alone for follicular lymphoma (FL) in adults who did not respond to a rituximab-containing regimen, or whose FL returned after such treatment.
- With chemotherapy, followed by Gazyva alone in those who responded, to treat stage II bulky, III, or IV FL in adults who have not had previous FL treatment.
Important Safety Information
The most important safety information patients should know about Gazyva
Patients must tell their doctor right away about any side effect 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 the patient has a 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 patients doctor or healthcare team will need to screen them for hepatitis B before, and monitor the patient for hepatitis during and after, their 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. The patients weakened immune system could put them at risk. The patients doctor will watch for symptoms. Symptoms of PML include: confusion, difficulty talking or walking, dizziness or loss of balance, and vision problems
Who should not receive Gazyva:
Patients should NOT receive Gazyva if they have had an allergic reaction (e.g., anaphylaxis or serum sickness) to Gazyva. Patients must tell their healthcare provider if they have had an allergic reaction to obinutuzumab or any other ingredients in Gazyva in the past.
Additional possible serious side effects of Gazyva:
Patients must tell their doctor right away about any side effect 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 the patient has a reaction, the infusion is either slowed or stopped until their symptoms are resolved. Most patients are able to complete infusions and receive medication again. However, if the infusion reaction is life threatening, the infusion of Gazyva will be permanently stopped. The patients 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. Symptoms of infusion reactions may include: fast heartbeat, tiredness, dizziness, headache, redness of the face, nausea, chills, fever, vomiting, diarrhea, rash, high blood pressure, low blood pressure, difficulty breathing, and chest discomfort
- Hypersensitivity Reactions Including Serum Sickness: Some patients receiving Gazyva may have severe or life-threatening allergic reactions. This reaction may be severe, may happen during or after an infusion, and may affect many areas of the body. If an allergic reaction occurs, the patients doctor will stop the infusion and permanently discontinue Gazyva
- Tumor Lysis Syndrome (TLS): Tumor lysis syndrome, including fatal cases, has been reported in patients receiving Gazyva. 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. The patients doctor may prescribe medication to help prevent TLS. The patients doctor will also conduct regular blood tests to check for TLS. Symptoms of TLS may include nausea, vomiting, diarrhea, and tiredness
- Infections: While the patient is taking Gazyva, they may develop infections. Some of these infections may be fatal and severe, so the patient should be sure to talk to their doctor if they think they have an infection. Patients administered Gazyva in combination with chemotherapy, followed by Gazyva alone are at a high risk of infections during and after treatment. Patients with a history of recurring or chronic infections may be at an increased risk of infection. Patients with an active infection should not be treated with Gazyva. Patients taking Gazyva plus bendamustine may be at higher risk for fatal or severe infections compared to patients taking Gazyva plus CHOP or CVP
- Low White Blood Cell Count: When the patient has an abnormally low count of infection-fighting white blood cells, it is called neutropenia. While the patient is taking Gazyva, their doctor will do blood work to check their white blood cell count. Severe and life-threatening neutropenia can develop during or after treatment with Gazyva. Some cases of neutropenia can last for more than one month. If the patients white blood cell count is low, their 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 their blood; having low platelet count is called thrombocytopenia. This may affect the clotting process. While the patient is taking Gazyva, their doctor will do blood work to check their platelet count. Severe and life-threatening thrombocytopenia can develop during treatment with Gazyva. Fatal bleeding events have occurred in patients treated with Gazyva. If the patients platelet count gets too low, their treatment may be delayed or reduced
The most common side effects of Gazyva in CLL were infusion reactions, low white blood cell counts, low platelet counts, low red blood cell counts, fever, cough, nausea, and diarrhea.
The safety of Gazyva was evaluated based on 392 patients with relapsed or refractory NHL, including FL (81 percent), small lymphocytic lymphoma (SLL) and marginal zone lymphoma (MZL) (a disease for which Gazyva is not indicated), who did not respond to or progressed within 6 months of treatment with rituximab product or a rituximab product-containing regimen. In patients with follicular lymphoma, the profile of side effects that were seen were consistent with the overall population who had NHL. The most common side effects of Gazyva were infusion reactions, low white blood cell counts, nausea, fatigue, cough, diarrhea, constipation, fever, low platelet counts, vomiting, upper respiratory tract infection, decreased appetite, joint or muscle pain, sinusitis, low red blood cell counts, general weakness, and urinary tract infection.
A randomized, open-label multicenter trial (GALLIUM) evaluated the safety of Gazyva as compared to rituximab product in 1,385 patients with previously untreated follicular lymphoma (86%) or marginal zone lymphoma (14%).The most common side effects of Gazyva were infusion reactions, low white blood cell count, upper respiratory tract infection, cough, constipation, and diarrhea.
Before receiving Gazyva, patients should talk to their doctor about:
- Immunizations: Before receiving Gazyva therapy, the patient should tell their healthcare provider if they have recently received or are scheduled to receive a vaccine. Patients who are treated with Gazyva should not receive live vaccines
- Pregnancy: The patient should tell their doctor if they are pregnant, think that they might be pregnant, plan to become pregnant, or are breastfeeding. Gazyva may harm their unborn baby. The patient should speak to their doctor about using Gazyva while they are pregnant. The patient should talk to their doctor or their childs doctor about the safety and timing of live virus vaccinations to their infant if they received Gazyva during pregnancy. It is not known if Gazyva may pass into the patients breast milk. The patient should speak to their doctor about using Gazyva if they are breastfeeding
Patients should 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.
