NORTH CHICAGO, Illinois, Dec. 8, 2016 /PRNewswire/ -- AbbVie (NYSE: ABBV), a global biopharmaceutical company, today announced the European Commission (EC) has granted conditional marketing authorization for VENCLYXTO™ (venetoclax) monotherapy for the treatment of chronic lymphocytic leukaemia (CLL) in the presence of 17p deletion or TP53 mutation in adult patients who are unsuitable for or have failed a B-cell receptor pathway inhibitor; and for the treatment of CLL in the absence of 17p deletion or TP53 mutation in adult patients who have failed both chemoimmunotherapy and a B-cell receptor pathway inhibitor.1 The EC approved VENCLYXTO as a first-in-class, oral, once-daily medicine that selectively inhibits the function of the BCL-2 protein.1 BCL-2 prevents the natural death of cells, including CLL cells.1 VENCLYXTO is being developed by AbbVie and Genentech, a member of the Roche Group. It is jointly commercialized by the companies in the U.S. and by AbbVie outside of the U.S.
"The European approval of VENCLYXTO is an important step forward for patients with chronic lymphocytic leukaemia in Europe," said Richard Gonzalez, chairman of the board and chief executive officer of AbbVie. "AbbVie has led the way in researching ways to block BCL-2 activity, and, as the first approved BCL-2 inhibitor in Europe, VENCLYXTO delivers on AbbVie's promise to develop cancer medicines where an unmet need exists."
CLL, a cancer of the bone marrow and blood, is typically a slow-progressing cancer.2 The 17p deletion, a genomic alteration in which a part of chromosome 17 is absent, is found in 3 to 10 percent of previously untreated CLL cases and up to 30 to 50 percent of relapsed or refractory CLL cases.3 A TP53 mutation occurs in 8 to 15 percent of patients at first-line treatment and up to 35 to 50 percent of cases in refractory CLL.3 Those with the 17p deletion or TP53 mutations often have a particularly poor prognosis3 and a median life expectancy of less than two to three years with current standard-of-care regimens.4
Conditional marketing authorization is granted to medicines that address an unmet medical need, where the benefit of its immediate availability to patients outweighs the risk of limited data availability, and where comprehensive data will be provided.5
"Results from the clinical trial program show that VENCLYXTO provides significant overall response among both patients with previously treated CLL with 17p deletion and patients with CLL who had been previously treated with and failed a B-cell receptor inhibitor," said Stephan Stilgenbauer, M.D., Ulm University, Germany, investigator in the VENCLYXTO clinical trial program. "While advances in treatment over the past few years have been meaningful for patients in Europe living with CLL, new options are still needed."
"The approval of VENCLYXTO represents an innovation in treatment options for people living with CLL who may harbor the 17p deletion or TP53 mutation and typically have a poor prognosis," said Michael Severino, M.D., executive vice president of research and development and chief scientific officer, AbbVie. "With this approval, we are pleased to be able to bring a new treatment option to patients in more countries around the world with this difficult-to-treat cancer."
In October 2016, AbbVie announced the European Committee for Medicinal Products for Human Use (CHMP) granted a positive opinion for the conditional marketing authorization of VENCLYXTO.6 Additionally, the European Medicines Agency (EMA) granted Orphan Drug Designation to VENCLYXTO for the treatment of multiple myeloma,7 a type of cancer that forms in plasma cells in bone marrow,8 and for diffuse large B-cell lymphoma (DLBCL),9 an aggressive type of lymphoma and the most common form of non-Hodgkin lymphoma (NHL).10 Previously, the EMA granted Orphan Drug Designation to VENCLYXTO for the treatment of CLL6 and for the treatment of acute myeloid leukaemia (AML),11 the most common type of acute leukaemia in adults.12 Orphan Drug Designation is granted to therapies aimed at the treatment, prevention or diagnosis of life-threatening diseases that affect no more than five in 10,000 persons in the EU and for which no satisfactory therapy is available. The medicine must also provide significant benefit to those affected by the condition.13
VENCLYXTO Clinical Trial Program
Study 1: Previously treated patients with CLL harboring 17p deletion
The safety and efficacy of VENCLYXTO was evaluated in a Phase 2, single arm, open-label, multi-center study in 107 patients (main cohort) with previously treated CLL with 17p deletion, with an additional 51 patients in a safety expansion cohort. Patients followed a 4- to 5-week dose-titration schedule starting at 20 mg and increasing to 50 mg, 100 mg, 200 mg and finally 400 mg once-daily. Patients continued to receive VENCLYXTO 400 mg once daily until disease progression or unacceptable toxicity was observed. The median time on treatment at the time of evaluation was 12 months (range: 0 to 22 months) for the main cohort. The median time on treatment for the combined cohort (main cohort plus safety expansion cohort, N=158) was 25 months (range: 0.5 to 50 months). The main cohort was assessed by an independent review committee, while the combined cohort was assessed by the investigators. Results showed:1
Study 2: Patients with CLL who have failed a B-cell receptor inhibitor
The safety and efficacy of VENCLYXTO was evaluated in a Phase 2 open-label, multi-center, non-randomized study in patients with CLL who had been previously treated with and failed ibrutinib (median number of prior oncology treatments was 4 [range: 1 to 12]) or idelalisib (median number of prior oncology treatments was 3 [range: 1 to 11]) therapy. Patients received VENCLYXTO via a recommended dose-titration schedule. Patients continued to receive VENCLYXTO 400 mg once daily until disease progression or unacceptable toxicity was observed. At the time of data cut-off, 64 patients were enrolled and treated with VENCLYXTO. Of these, 43 patients had received prior ibrutinib therapy (Arm A) and 21 had received prior idelalisib therapy (Arm B). Of the patients, 91 percent (39/42) in Arm A and 67 percent (14/21) in Arm B had relapsed on or were refractory to ibrutinib and idelalisib, respectively. Chromosomal aberrations were 11q deletion (30%, 19/62), 17p deletion (36%, 23/61), TP53 mutation (26%, 16/61) and unmutated IgVH (86%, 36/42). At the time of evaluation, median duration of treatment with VENCLYXTO was 11.7 months (range: 0.1 to 17.9 months). Results showed:1
The safety of VENCLYXTO is based on pooled data of 296 patients treated in two Phase 2 studies and one Phase 1 study. In all, the studies enrolled patients with previously treated CLL, including 188 patients with 17p deletion and 92 patients who had failed a B-cell receptor inhibitor. The most commonly occurring adverse reactions (≥20 percent) of any grade in patients receiving VENCLYXTO were neutropenia/neutrophil count decreased, diarrhoea, nausea, anemia, upper respiratory tract infection, fatigue, hyperphosphatemia, vomiting and constipation. The most frequently reported serious adverse reactions (≥2 percent) were pneumonia, febrile neutropenia and tumour lysis syndrome (TLS). Discontinuations due to adverse reactions occurred in 9.1 percent of patients. Dosage adjustments due to adverse reactions occurred in 11.8 percent of patients.1
About VENCLYXTO™ (venetoclax)
VENCLYXTO™ (venetoclax), an oral B-cell lymphoma-2 (BCL-2) inhibitor, is indicated for the treatment of chronic lymphocytic leukaemia (CLL) in the presence of 17p deletion or TP53 mutation in adult patients who are unsuitable for or have failed a B-cell receptor pathway inhibitor; and for the treatment of CLL in the absence of 17p deletion or TP53 mutation in adult patients who have failed both chemoimmunotherapy and a B-cell receptor pathway inhibitor.1 It is also being evaluated for the treatment of patients with various blood cancer types.1,14,15,16,17 The BCL-2 protein prevents apoptosis (programmed cell death) of some cells, including lymphocytes, and can be overexpressed in CLL cells.1 VENCLYXTO, which is given once-daily, is designed to selectively inhibit the function of the BCL-2 protein.1
VENCLYXTO is being developed by AbbVie and Genentech, a member of the Roche Group. It is jointly commercialized by the companies in the U.S. and by AbbVie outside of the U.S. Together, the companies are committed to BCL-2 research with venetoclax, which is currently being evaluated in Phase 3 clinical trials for the treatment of relapsed/refractory CLL, along with studies in several other cancers.
In April 2016, the U.S. Food and Drug Administration (FDA) granted accelerated approval of VENCLEXTA™ (venetoclax) tablets 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.18 The FDA approved this indication under accelerated approval based on overall response rate, and continued approval may be contingent upon verification and description of clinical benefit in a confirmatory trial.18 Venetoclax is also currently approved in Argentina, Puerto Rico and Canada. AbbVie, in collaboration with Roche and Genentech, is currently working with regulatory agencies around the world to bring this medicine to eligible patients in need.
Important EU Safety Information
Contraindications
Concomitant use of strong CYP3A inhibitors at initiation and during the dose-titration phase due to increased risk for tumour lysis syndrome (TLS). Concomitant use of preparations containing St. John's wort as VENCLYXTO efficacy may be reduced. Hypersensitivity to the active substance or to any of the excipients is contraindicated.
Special Warnings & Precautions for Use
Tumour lysis syndrome (TLS), including fatal events, has occurred in patients with previously treated CLL with high tumour burden when treated with VENCLYXTO. VENCLYXTO poses a risk for TLS in the initial 5-week ramp-up phase. Changes in blood chemistries consistent with TLS that require prompt management can occur as early as 6 to 8 hours following the first dose of VENCLYXTO and at each dose increase. Patients should be assessed for risk and should receive appropriate prophylaxis for TLS. Blood chemistries should be monitored and abnormalities managed promptly. More intensive measures (including hospitalization) should be employed as overall risk increases.
Neutropenia (grade 3 or 4) has been reported and complete blood counts should be monitored throughout the treatment period.
Live vaccines should not be administered during treatment or thereafter until B-cell recovery.
Drug Interactions
CYP3A inhibitors may increase VENCLYXTO plasma concentrations. At initiation and dose-titration phase: Strong CYP3A inhibitors are contraindicated and moderate CYP3A inhibitors should be avoided. If moderate CYP3A inhibitors must be used, physicians should refer to the SmPC for dose adjustment recommendations. At steady daily dose: If moderate or strong CYP3A inhibitors must be used, physicians should refer to the SmPC for dose adjustment recommendations.
Avoid concomitant use of P-gp and BCRP inhibitors at initiation and during the dose titration phase.
CYP3A4 inducers may decrease VENCLYXTO plasma concentrations. Avoid coadministration with strong or moderate CYP3A inducers.
Co-administration of bile acid sequestrants with VENCLYXTO is not recommended as this may reduce the absorption of VENCLYXTO.
Adverse Reactions
The most commonly occurring adverse reactions (>=20%) of any grade were neutropenia/neutrophil count decreased, diarrhoea, nausea, anemia, upper respiratory tract infection, fatigue, hyperphosphatemia, vomiting and constipation.
The most frequently occurring adverse reactions (>=2%) were pneumonia, febrile neutropenia and TLS.
Discontinuations due to adverse reactions occurred in 9.1% of patients and dosage adjustments due to adverse reactions occurred in 11.8% of patients.
Specific Populations
VENCLYXTO may cause embryo-fetal harm when administered to a pregnant woman. Advise females of reproductive potential to avoid pregnancy during treatment. Advise nursing women to discontinue breastfeeding during treatment.
