Venetoclax

First all-oral, fixed-duration combination regimen approved for previously untreated patients with CLL Approval supported by data from the Phase 3 AMPLIFY trial Regimen offers another option for the potential of time off treatment, marking a meaningful advance in long-term disease management NORTH CHICAGO, Ill., Feb. 20, 2026 /PRNewswire/ -- AbbVie (NYSE: ABBV) today announced that the U.S. Food and Drug Administration (FDA) has approved a supplemental new drug application (sNDA) for the combination regimen of VENCLEXTA® (venetoclax) and acalabrutinib for the treatment of previously untreated adult patients with chronic lymphocytic leukemia (CLL). The approval is supported by data from the Phase 3 AMPLIFY trial.1 This milestone updates the treatment of CLL in the first-line setting, establishing the VENCLEXTA and acalabrutinib combination as the first and only all-oral, fixed-duration regimen for previously untreated patients. The regimen supports current standards of care by offering patients the potential for time off treatment and giving providers a new, targeted option that combines two classes of oral medications for CLL. "This FDA approval marks a significant milestone for AbbVie and, more importantly, for people living with CLL," said Svetlana Kobina, vice president, global medical affairs, oncology, AbbVie. "As the first and only all-oral, fixed-duration combination regimen for previously untreated patients, the VENCLEXTA plus acalabrutinib approval expands choice and flexibility for patients and providers navigating complex treatment decisions in CLL." CLL is one of the most common forms of leukemia in adults and is a type of cancer that can develop from cells in the bone marrow that later mature into certain white blood cells (called lymphocytes).2 While outcomes have improved in recent years, patients often face long treatment durations and ongoing disease management challenges. "With the FDA approval of the combination of venetoclax and acalabrutinib for use as a front-line therapy in CLL, patients in the USA now have an all oral, time-limited option that can be important for many in choosing their treatment," said Dr. Brian Koffman, co-founder and chief medical officer emeritus, CLL Society. "CLL Society is pleased to see the number of choices available for patients growing." About the AMPLIFY Study AMPLIFY is an AstraZeneca-sponsored, global, multi-center Phase 3 trial evaluating VENCLEXTA plus acalabrutinib alone or combined with obinutuzumab versus chemoimmunotherapy (investigator's choice of fludarabine-cyclophosphamide-rituximab [FCR] or bendamustine-rituximab [BR]) in patients with previously untreated CLL without del(17p) or TP53 mutation.1 VENCLEXTA plus acalabrutinib were administered for a fixed duration of 14 cycles, each consisting of 28 days, while chemoimmunotherapy was administered for six cycles according to regimens. VENCLEXTA was started on cycle 3 of 14 with a 5-week ramp-up schedule. Results from the AMPLIFY study showed that the fixed-duration combination regimen of VENCLEXTA and acalabrutinib was superior to FCR/BR chemoimmunotherapy. Study results showed the combination regimen of VENCLEXTA and acalabrutinib reduced the risk of disease progression or death by 35% versus chemoimmunotherapy (HR 0.65; 95% CI: 0.49-0.87; p=0.0038). Median progression-free survival (PFS) was not reached versus 47.6 months for chemoimmunotherapy. The safety profile of the VENCLEXTA and acalabrutinib combination regimen is consistent with the known safety profile of each individual therapy alone. In CLL/SLL, the most common adverse reactions (≥20%) for VENCLEXTA when given in combination with acalabrutinib are neutropenia, headache, diarrhea, musculoskeletal pain, and COVID-19. The most common serious adverse reactions (≥2%) in patients receiving V+A were COVID-19, including COVID-19 pneumonia (9%), second primary malignancies (2.7%), and neutropenia (2.1%). In patients treated with VENCLEXTA plus acalabrutinib, the incidence of tumor lysis syndrome was 0.3%. No new safety signals were observed in the AMPLIFY study.3 About VENCLEXTA® (venetoclax) VENCLEXTA (venetoclax) 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. 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. Venetoclax is approved in more than 80 countries, including the U.S. VENCLEXTA® (venetoclax) U.S. Uses and Important Safety Information4 Uses VENCLEXTA is a prescription medicine used: to treat adults with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL). 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 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 and during treatment with VENCLEXTA. It is important to keep your appointments for blood tests. Tell your healthcare provider right away if you get 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 during treatment with 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 get symptoms of TLS. When restarting VENCLEXTA after stopping for 1 week or longer, your healthcare provider may check again for your risk of TLS and change your dose. Who should not take VENCLEXTA? Patients taking certain medicines during the beginning of VENCLEXTA (when the dose is being slowly increased) are at increased risk of TLS. Tell your healthcare provider about all the medicines you take, including prescription and over-the- counter medicines, vitamins, and herbal supplements. VENCLEXTA and other medicines may affect each other causing serious side effects. Do not start new medicines during treatment with VENCLEXTA without first talking with your healthcare provider.

The FDA approved AstraZeneca's BTK inhibitor Calquence (acalabrutinib) in combination with AbbVie and Roche's BCL-2 inhibitor Venclexta (venetoclax) — also marketed by AbbVie as Venclyxto in the EU — for the first-line treatment of chronic lymphocytic leukaemia (CLL) in adults, establishing the first and only all-oral, fixed-duration combination therapy for previously untreated patients. Also see – Spotlight On: BTK inhibitors move towards fixed-duration combos in CLL."The…approval expands choice and flexibility for patients and providers navigating complex treatment decisions in CLL," said Svetlana Kobina, VP of oncology global medical affairs at AbbVie. Similar to the Calquence–Venclexta pair's EU approval for the indication last year, the latest US clearance was supported by the Phase III AMPLIFY trial. Results showed the experimental duo with or without Roche's Gazyva/Gazyvaro (obinutuzumab) demonstrated a 35% reduction in the risk of disease progression or death versus chemoimmunotherapy in treatment-naïve patients, with median progression-free survival not reached in the combination arm compared with 47.6 months for chemoimmunotherapy.In a FirstWord poll of US haematologists and oncologists conducted post the AMPLIFY readout, 85% of respondents were at least somewhat impressed by the data and over half deemed the all-oral, fixed-duration regimen as highly promising. However, in a separate CLL landscape report, key opinion leaders also expressed concerns that the combination was pitted against a relatively outdated chemoimmunotherapy control arm. Meanwhile, another late-stage study, MAJIC, is evaluating the Calquence-Venclexta combination against Venclexta plus Gazyva for CLL or small lymphocytic lymphoma in the front-line setting.
