NORTH CHICAGO, Ill., March 7, 2019 /PRNewswire/ -- AbbVie (NYSE: ABBV), a research-based global biopharmaceutical company,
The FDA will review the venetoclax and obinutuzumab combination under its Real-Time Oncology Review (RTOR) pilot program, which aims to explore a more efficient review process to ensure safe and effective cancer medicines are available to patients as early as possible.
"We studied the venetoclax and obinutuzumab combination with a fixed treatment duration and found these medicines, used together, may enable some CLL patients to live longer without their disease getting worse, leading to longer progression-free survival, while remaining off therapy," said Mohamed Zaki, M.D., Ph.D., vice president, global head of hematology development, AbbVie. "Under the RTOR program, we are determined to work with the FDA and bring this first- and only-in-class medicine to previously-untreated CLL patients earlier than expected."
The sNDA for the venetoclax and obinutuzumab combination is based on data from the Phase 3 CLL14 trial, which studied patients receiving the combination treatment for 12 months as their first treatment for CLL. CLL14 is the first randomized trial in CLL to examine a chemotherapy-free, fixed duration treatment regimen.
The FDA's standard review time for drug applications is six to 10 months.1 The RTOR program focuses on the early submission of data most relevant to assessing the product's safety and effectiveness. RTOR allows the FDA to review much of the data before it is formally submitted to the FDA.
VENCLEXTA® (venetoclax) is being developed by AbbVie and Roche. It is jointly commercialized by AbbVie and Genentech, a member of the Roche Group, in the U.S. and by AbbVie outside of the U.S.
About Chronic Lymphocytic LeukemiaCLL is typically a slow-progressing cancer of the bone marrow and blood in which types of white blood cells called B lymphocytes become cancerous and multiply abnormally.2 In the U.S., CLL accounts for more than 20,000 newly diagnosed cases of leukemia each year.2
About the Phase 3 CLL14 TrialThe prospective, multicenter, open-label, randomized Phase 3 CLL14 trial, which was conducted in close collaboration with the German CLL Study Group (DCLLSG), evaluated the efficacy and safety of a combined regimen of venetoclax and obinutuzumab (n=216) versus obinutuzumab and chlorambucil (n=216) in previously-untreated patients with CLL and coexisting medical conditions. The therapies were administered for a fixed duration of 12 months for venetoclax in combination with six cycles of obinutuzumab. The trial enrolled 445 patients, all of whom were previously-untreated according to the International Workshop on Chronic Lymphocytic Leukemia (iwCLL) criteria. The primary endpoint was progression-free survival (PFS) based on investigator assessment, using iwCLL criteria.3
Key secondary endpoints were PFS as assessed by an independent review committee, minimal residual disease (MRD)-negativity in peripheral blood and bone marrow, overall and complete response rates, MRD-negativity in complete response in peripheral blood and bone marrow, and overall survival.
About VENCLEXTA® (venetoclax tablets) (US) VENCLEXTA® is a first-in-class medicine that selectively binds and inhibits the B-cell lymphoma-2 (BCL-2) protein. In some blood cancers, BCL-2 prevents cancer cells from undergoing their natural death or self-destruction process, called apoptosis. VENCLEXTA targets the BCL-2 protein and works to help restore the process of apoptosis.4
VENCLEXTA is being developed by AbbVie and Roche. It is jointly commercialized by AbbVie and Genentech, a member of the Roche Group, in the U.S. and by AbbVie outside of the U.S. Together, the companies are committed to BCL-2 research and to studying venetoclax in clinical trials across several blood and other cancers.
The efficacy and safety of venetoclax in patients with previously-untreated CLL has not been evaluated by the U.S. Food and Drug Administration, the European Medicines Agency or any health authority.
In April 2016, the U.S. FDA first granted accelerated approval of VENCLEXTA for the treatment of patients with CLL with 17p deletion, as detected by an FDA-approved test, who have received at least one prior therapy.5 The FDA approved this indication under accelerated approval based on overall response rate.5 Based on the results of the MURANO study, VENCLEXTA was approved in June 2018 for the treatment of patients with CLL or small lymphocytic lymphoma (SLL), with or without 17p deletion, who have received at least one prior therapy.4 In November 2018, VENCLEXTA was approved 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.6
Venetoclax is approved in more than 50 countries, including the U.S. AbbVie, in collaboration with Roche, is currently working with regulatory agencies around the world to bring this medicine to additional eligible patients in need.

It is not known if VENCLEXTA is safe and effective in children.
Important Safety Information
What is the most important information I should know about VENCLEXTA?
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. Your healthcare provider will do tests to check your risk of getting TLS before you start taking VENCLEXTA. You will receive other medicines before starting and during treatment with VENCLEXTA to help reduce your risk of TLS. You may also need to receive intravenous (IV) fluids into your vein. Your healthcare provider will do blood tests to check for TLS when you first start treatment and during treatment with VENCLEXTA.
It is important to keep your appointments for blood tests. Tell your healthcare provider right away if you 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.
Drink plenty of water when taking VENCLEXTA to help reduce your risk of getting TLS. Drink 6 to 8 glasses (about 56 ounces total) of water each day, starting 2 days before your first dose, on the day of your first dose of VENCLEXTA, and each time your dose is increased.Your healthcare provider may delay, decrease your dose, or stop treatment with VENCLEXTA if you have side effects.
Who should not take VENCLEXTA?
Certain medicines must not be taken when you first start taking VENCLEXTA and while your dose is being slowly increased because of the risk of increased TLS.
Before taking VENCLEXTA, tell your healthcare provider about all of your medical conditions, including if you:
What should I avoid while taking VENCLEXTA?You should not drink grapefruit juice or eat grapefruit, Seville oranges (often used in marmalades), or starfruit while you are taking VENCLEXTA. These products may increase the amount of VENCLEXTA in your blood.
What are the possible side effects of VENCLEXTA?
VENCLEXTA can cause serious side effects, including:
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 your 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 your 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 your ability to father a child. Talk to your healthcare provider if you have concerns about fertility.
These are not all the possible side effects of VENCLEXTA. For more information, ask your healthcare provider or pharmacist.
