The Phase III CLL14 study compared Venclexta in combination with Gazyva to standard-of-care Gazyva plus chlorambucil
Data will be submitted to health authorities and presented at an upcoming medical meeting
South San Francisco, CA -- October 31, 2018 --
Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), announced today that the randomized Phase III CLL14 study, which evaluated fixed-duration Venclexta® (venetoclax) in combination with Gazyva® (obinutuzumab) in people with previously untreated chronic lymphocytic leukemia (CLL) and co-existing medical conditions, 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. The results showed that no new safety signals or increase in known toxicities of Venclexta or Gazyva were observed with the treatment combination.
“People with chronic lymphocytic leukemia continue to need more treatment options because some patients are unable to tolerate chemotherapy regimens due to their underlying health,” said Sandra Horning, M.D., chief medical officer and head of Global Product Development. “CLL14 is the first study to show superior progression-free survival for Venclexta plus Gazyva compared to a standard-of-care regimen. We will work with health authorities to bring this potential chemotherapy-free treatment option to people who need it as quickly as possible.”
Data from the CLL14 study will be submitted to global health authorities. Venclexta in combination with Rituxan® (rituximab) has been approved by the U.S. Food and Drug Administration (FDA) for the treatment of people with CLL or small lymphocytic lymphoma, with or without 17p deletion, who have received at least one prior therapy. A supplemental New Drug Application (sNDA) is currently under review by the FDA for Venclexta in combination with a hypomethylating agent or in combination with low dose cytarabine for the treatment of people with previously untreated acute myeloid leukemia (AML) who are ineligible for intensive chemotherapy, with a decision expected by end of year.
A robust clinical development program for Venclexta is ongoing in several types of blood cancer, including AML and multiple myeloma. Gazyva continues to be investigated in combination with approved and investigational molecules in CLL and follicular lymphoma.
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) with coexisting medical conditions. 432 patients with previously untreated CLL were randomly assigned to receive either Venclexta plus Gazyva (Arm A) or Gazyva plus 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, best overall response, complete response, duration of response, overall survival, event-free survival, time to next CLL treatment, minimal residual disease status 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.
About Chronic Lymphocytic Leukemia (CLL)
Chronic lymphocytic leukemia (CLL) is the most common type of adult leukemia, and in 2018, it is estimated there will be more than 20,000 new cases of CLL diagnosed in the United States. 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 small molecule designed to selectively bind and inhibit the BCL-2 protein, which plays an important role in a process called apoptosis (programmed cell death). Overexpression of the BCL-2 protein in CLL has been associated with resistance to certain therapies. It is believed that blocking BCL-2 may restore the signaling system that tells cells, including cancer cells, to self-destruct. 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 further research with Venclexta, which is currently being evaluated in PhaseIII clinical trials for the treatment of CLL, along with studies in several other types of cancers. In the United States, Venclexta has been granted four Breakthrough Therapy Designations by the FDA: 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 (LDAC) for people with untreated AML ineligible for intensive chemotherapy.
Venclexta is a prescription medicine used to treat people with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL), with or without 17p deletion, who have received at least one prior treatment.
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. A patient’s doctor will do tests for TLS. It is important for patients taking Venclexta to keep their appointments for blood tests. Patients will receive other medicines before starting and during treatment with Venclexta to help reduce the risk of TLS. Patients may also need to receive intravenous (IV) fluids into their vein. Patients taking Venclexta must 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 when taking 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 their first dose, on the day of their first dose of Venclexta, and each time the dose is increased.
Certain medicines must not be taken when patients first start taking Venclexta and while their dose is being slowly increased because of the risk of increased tumor lysis syndrome.
Before taking Venclexta, patients must tell their doctor about all of their medical conditions, including if they:
Patients should not drink grapefruit juice or 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 patient’s blood.
Venclexta can cause serious side effects, including:
The most common side effects of Venclexta when used in combination with rituximab include low white blood cell count, diarrhea, upper respiratory tract infection, cough, tiredness, and nausea.
The most common side effects of Venclexta when used alone include low white blood cell count, diarrhea, nausea, upper respiratory tract infection, low red blood cell count, tiredness, low platelet count, muscle and joint pain, swelling of the arms, legs, hands, and feet, and cough.
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 must tell their doctor if they have any side effect that bothers them or that does not go away.

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.

About the German CLL Study Group (GCLLSG)
Founded in 1996 and headed by Michael Hallek, M.D., the GCLLSG has been running various Phase III, Phase II and Phase I trials in chronic lymphocytic leukemia (CLL) with the goal to provide optimal treatment to patients suffering from this disease. Among those were landmark trials like the CLL8 and the CLL11 trials which led to the current standard-of-care in CLL. For many years, GCLLSG has been aiming to improve not just the treatment of younger and physically fit patients, but also that of elderly and less fit patients. These patients are generally underrepresented in clinical trials although they constitute the majority of CLL patients treated by doctors in daily practice. The GCLLSG is an independent non-profit research organization supported by the German Cancer Aid (Deutsche Krebshilfe). www.dcllsg.de.
