Roche (SIX: RO, ROG; OTCQX: RHHBY) today announced results from the pivotal phase III CLL14 study in previously untreated chronic lymphocytic leukaemia (CLL) showing that Venclexta®/Venclyxto® (venetoclax) plus Gazyva®/Gazyvaro® (obinutuzumab) met its primary endpoint of investigator-assessed progression-free survival (PFS), wie die Roche schreibt.

The 12-month, fixed-duration, chemotherapy-free combination reduced the risk of disease worsening or death by 65% compared to Gazyva/Gazyvaro plus chlorambucil (PFS, as assessed by investigator; HR=0.35; 95% CI 0.23-0.53; p<0.001), when given to people with previously untreated CLL who have co-existing medical conditions. The results were presented at the 2019 American Society of Clinical Oncology (ASCO) Annual Meeting and simultaneously published in the New England Journal of Medicine (NEJM).1,2At two years, one year after stopping treatment, nearly nine out of ten patients (88.2%) in the Venclexta/Venclyxto plus Gazyva/Gazyvaro arm remained progression-free, compared to 64.1% in the Gazyva/Gazyvaro plus chlorambucil arm.

Safety for Venclexta/Venclyxto plus Gazyva/Gazyvaro appeared consistent with the known safety profiles of the individual medicines. Common Grade 3-4 adverse events with Venclexta/Venclyxto plus Gazyva/Gazyvaro compared to Gazyva/Gazyvaro plus chlorambucil, respectively, were low white blood cell count (52.8% vs.

48.1%) and infections (17.5% vs. 15.0%).The US Food and Drug Administration (FDA) approved the combination on 15 May 2019, under the FDA’s Real-Time Oncology Review and Assessment Aid pilot programmes, for the treatment of people with previously untreated CLL or small lymphocytic lymphoma.

This is the second regimen of Roche medicines approved under the RTOR pilot programme, which is exploring a more efficient review process to ensure safe and effective treatments are available to patients as early as possible. Additional submissions of the CLL14 data to health authorities around the world are ongoing.CLL14 (NCT02242942) is a randomised phase III study evaluating the combination of fixed-duration Venclexta/Venclyxto plus Gazyva/Gazyvaro compared to Gazyva/Gazyvaro plus chlorambucil in patients with previously untreated chronic lymphocytic leukaemia (CLL) and co-existing medical conditions.

Co-existing medical conditions included reduced kidney function or co-morbidities assessed by a standard scale (Cumulative Illness Rating Scale). 432 patients with previously untreated CLL were randomly assigned to receive either a 12-month duration of Venclexta/Venclyxto alongside six-month duration of Gazyva/Gazyvaro (Arm A) or six-month duration of Gazyva/Gazyvaro alongside 12-month duration of chlorambucil (Arm B).

Arm A started with an initial dosing of Gazyva/Gazyvaro followed by a five-week Venclexta/Venclyxto dose ramp-up to help reduce the risk of tumour lysis syndrome. The primary endpoint of the study is investigator-assessed progression-free survival (PFS).

Secondary endpoints include PFS assessed by independent review committee (IRC), minimal residual disease (MRD) status, overall response rate (ORR), complete response (with or without complete blood count recovery), overall survival, duration of response, event-free survival, time to next CLL treatment, and safety. The CLL14 study is being conducted in cooperation with the German CLL Study Group, headed by Michael Hallek, MD, University of Cologne.Venclexta/Venclyxto is a first-in-class targeted medicine designed to selectively bind and inhibit the B-cell lymphoma-2 (BCL-2) protein.

In some blood cancers and other tumours, BCL-2 builds up and prevents cancer cells from dying or self-destructing, a process called apoptosis. Venclexta/Venclyxto blocks the BCL-2 protein and works to restore the process of apoptosis.Venclexta/Venclyxto is being developed by AbbVie and Roche.

It is jointly commercialised by AbbVie and Genentech, a member of the Roche Group, in the US and by AbbVie outside of the US. Together, the companies are committed to research with Venclexta/Venclyxto, which is currently being studied in clinical trials across several types of blood and other cancers.Gazyva/Gazyvaro is an engineered monoclonal antibody designed to attach to CD20, a protein expressed on certain B-cells, but not on stem cells or plasma cells.

Gazyva/Gazyvaro is designed to attack and destroy targeted B-cells both directly and together with the body's immune system. Gazyva is marketed as Gazyvaro in the EU and Switzerland.Founded in 1996 and headed by Michael Hallek, MD, the GCLLSG has been running various phase III, phase II and phase I trials in chronic lymphocytic leukaemia (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 organisation supported by the German Cancer Aid (Deutsche Krebshilfe).

www.dcllsg.deRoche has been developing medicines for people with malignant and non-malignant blood diseases for over 20 years; our experience and knowledge in this therapeutic area runs deep. Today, we are investing more than ever in our effort to bring innovative treatment options to patients across a wide range of haematologic diseases.

Our approved medicines include MabThera®/Rituxan® (rituximab), Gazyva®/Gazyvaro® (obinutuzumab), Venclexta®/Venclyxto® (venetoclax) in collaboration with AbbVie, and Hemlibra® (emicizumab). Our pipeline of investigational haematology medicines includes polatuzumab vedotin, an anti-CD79b antibody drug conjugate; idasanutlin, a small molecule, which inhibits the interaction of MDM2 with p53; T-cell engaging bispecific antibodies targeting both CD20 and CD3, and Tecentriq® (atezolizumab), a monoclonal antibody designed to bind with PD-L1. Our scientific expertise, combined with the breadth of our portfolio and pipeline, also provides a unique opportunity to develop combination regimens that aim to improve the lives of patients even further.Roche is the world’s largest biotech company, with truly differentiated medicines in oncology, immunology, infectious diseases, ophthalmology and diseases of the central nervous system.
