Venetoclax is a highly selective, potent BCL-2 inhibitor that is approved for some patients previously treated for chronic lymphocytic leukemia, and has shown promising activity in adult studies across several hematologic malignancies. Preclinical studies have demonstrated venetoclax activity in pediatric patient-derived xenograft models and cell lines; however, clinical studies in pediatric patients have yet to be conducted. The prognosis is poor for children with most relapsed/refractory malignancies, and limited treatment options result in unmet clinical need...

BACKGROUND: Venetoclax inhibits BCL2, an antiapoptotic protein that is pathologically overexpressed and that is central to the survival of chronic lymphocytic leukemia cells. We evaluated the efficacy of venetoclax in combination with rituximab in patients with relapsed or refractory chronic lymphocytic leukemia. METHODS: In this randomized, open-label, phase 3 trial, we randomly assigned 389 patients to receive venetoclax for up to 2 years (from day 1 of cycle 1) plus rituximab for the first 6 months (venetoclax-rituximab group) or bendamustine plus rituximab for 6 months (bendamustine-rituximab group)...

Chronic lymphocytic leukemia (CLL) is a highly heterogeneous disease. Deregulation of apoptosis is a major pathogenetic feature, and represents a therapeutic target. TP53 disrupted patients are categorized as high risk patients and are treated with novel target therapies. Among these new drugs, venetoclax, an orally bioavailable BCL2 inhibitor, has shown high efficacy also in relapsed/refractory CLL with TP53 disruption. Venetoclax has also been tested in combination with other drugs without compromising venetoclax dose and with a good safety profile...

Resistance to apoptosis is one of the hallmarks of cancer and members of the B-cell lymphoma 2 (BCL-2) family of proteins are central regulators of apoptosis. Many cancers become resistant to chemotherapy and apoptosis by up-regulating BCL-2 and other family members, making these proteins attractive targets for cancer therapy. Venetoclax is an orally administered, small-molecule apoptosis stimulant that targets BCL-2 proteins by acting as a BCL-2 homology domain 3 (BH3) mimetic. The drug is approved in the USA and EU as a monotherapy for the for the treatment of certain patients with chronic lymphocytic leukemia (CLL) and is in phase III clinical development for multiple myeloma (MM), and in phase II or I/II clinical trials for acute myeloid leukemia, and several B-cell malignancies, including diffuse large B-cell lymphoma, Waldenstrom's macroglobulinaemia, follicular lymphoma, and mantle-cell lymphoma...

Inhibitors of anti-apoptotic proteins of the BCL2 family can successfully restart the deregulated process of apoptosis in malignant cells. While non-selective agents have been limited by their affinity to different BCL2 members, and thus inducing excessive toxicity, the highly selective BCL2 inhibitor, venetoclax (ABT-199, Venclexta™), has an acceptable safety profile. To date, it has been approved in monotherapy for the treatment of relapsed or refractory chronic lymphocytic leukaemia (CLL) with 17p deletion...

AIM: Four Phase II trials (Clinical Trials numbers: NCT02345863, NCT02401503, NCT02445131 and NCT02689141) evaluate a different combination of targeted agents in an all-comer population of approximately 60 patients with chronic lymphocytic leukemia irrespective of prior treatment, physical fitness and genetic risk factors. Patients with a higher tumor load start with a debulking treatment with bendamustine. The subsequent induction and maintenance treatment with an anti-CD20 antibody (obinutuzumab or ofatumumab) and a targeted oral agent (ibrutinib, idelalisib or venetoclax) are continued until achievement of a complete response and minimal residual disease negativity...

Deciphering the evolution of cancer cells under therapeutic pressure is a crucial step to understand the mechanisms that lead to treatment resistance. To this end, we analyzed whole-exome sequencing data of eight chronic lymphocytic leukemia (CLL) patients that developed resistance upon BCL2-inhibition by venetoclax. Here, we report recurrent mutations in BTG1 (2 patients) and homozygous deletions affecting CDKN2A/B (3 patients) that developed during treatment, as well as a mutation in BRAF and a high-level focal amplification of CD274 (PD-L1) that might pinpoint molecular aberrations offering structures for further therapeutic interventions...

The BCL2 inhibitor venetoclax is approved in the United States for only a subset of patients with refractory chronic lymphocytic leukemia. However, in light of data presented at the American Society of Hematology 2017 Annual Meeting, clinicians are thinking ahead to administering the drug more broadly-in combinations and as a first-line therapy-for other patients with the disease.

BACKGROUND AND OBJECTIVE: Venetoclax is an oral selective Bcl-2 inhibitor approved for the treatment of patients with chronic lymphocytic leukemia with 17p deletion. Mechanistic and preclinical evidence warranted evaluation of venetoclax for the treatment of systemic lupus erythematosus (SLE). This work characterized the pharmacokinetics of venetoclax in female subjects with SLE. METHODS: Single (10-500 mg) and multiple (30-600 mg) escalating doses of venetoclax or matching placebo were evaluated using randomized, double-blind, placebo-controlled designs (6 active and 2 placebo per dose with 73 unique SLE patients enrolled, 25 of whom enrolled twice)...

B-cell receptor pathway inhibitors (BCRi) have transformed treatment for chronic lymphocytic leukemia (CLL); however, efficacy of therapies for patients whose disease is refractory to/relapses after (R/R) BCRi is unknown. Venetoclax is a selective, orally bioavailable BCL-2 inhibitor with activity in patients with CLL, including those who are heavily pretreated or have 17p deletion. This phase 2 study prospectively evaluated venetoclax in patients with R/R CLL after ibrutinib or idelalisib; here we report on patients who received idelalisib as the last BCRi prior to enrollment...

BACKGROUND: Chronic lymphocytic leukaemia (CLL) frequently responds to chemoimmunotherapy combining cytotoxic chemotherapy and monoclonal antibodies. However, CLL is associated with significant genetic heterogeneity, and some high-risk forms are known to be chemo-resistant and associated with early relapse. AIMS: To review the current treatment paradigm of patients with high-risk disease, in particular those with del(17p) and TP53 variants. RESULTS: A 'watch and wait' approach is recommended for all patients who are asymptomatic...

BACKGROUND: Therapy targeting Bruton's tyrosine kinase (BTK) with ibrutinib has transformed the treatment of chronic lymphocytic leukaemia. However, patients who are refractory to or relapse after ibrutinib therapy have poor outcomes. Venetoclax is a selective, orally bioavailable inhibitor of BCL-2 active in previously treated patients with relapsed or refractory chronic lymphocytic leukaemia. In this study, we assessed the activity and safety of venetoclax in patients with chronic lymphocytic leukaemia who are refractory to or relapse during or after ibrutinib therapy...

Venetoclax is licensed to treat relapsed or refractory (R/R) chronic lymphocytic leukaemia (CLL). As part of the Single Technology Appraisal (STA) ID944, the National Institute for Health and Care Excellence (NICE) invited AbbVie, the manufacturer, to submit evidence on the use of venetoclax, within its licensed indication. The Evidence Review Group (ERG), Warwick Evidence, was asked to provide an independent and critical review of the submitted evidence. Evidence came from three single-arm trials in CLL patients with or without 17p deletion [del(17p])/TP53 chromosomal abnormalities...

With the recent approval of several effective and well-tolerated novel agents (NAs), including ibrutinib, idelalisib, venetoclax, and obinutuzumab, patients with chronic lymphocytic leukemia (CLL) have more therapeutic options than ever before. The availability of these agents is both an important advance for patients but also a challenge for practicing hematologist/oncologists to learn how best to sequence NAs, both with respect to chemoimmunotherapy (CIT) and to other NAs. The sequencing of NAs in clinical practice should be guided both by an individual patient's prognostic markers, such as FISH and immunoglobulin heavy chain variable region ( IGHV )-mutation status, as well as the patient's medical comorbidities and goals of care...

The typical genome of chronic lymphocytic leukemia (CLL) carries ∼2000 molecular lesions. Few mutations recur across patients at a frequency >5%, whereas a large number of biologically and clinically uncharacterized genes are mutated at lower frequency. Approximately 80% of CLL patients carry at least 1 of 4 common chromosomal alterations, namely deletion 13q14, deletion 11q22-23, deletion 17p12, and trisomy 12. Knowledge of the CLL genome has translated into the availability of molecular biomarkers for prognosis and treatment prediction...
