Basel, 5 December 2020 – Roche (SIX: RO, ROG; OTCQX: RHHBY) today announced that new data from the pivotal phase III MURANO and CLL14 studies support the efficacy of fixed-duration, chemotherapy-free Venclexta®/Venclyxto® (venetoclax)-based combinations in certain people with chronic lymphocytic leukaemia (CLL) and provide more evidence on the potential value of minimal residual disease (MRD). Data were presented at the all-virtual 62nd American Society of Hematology (ASH) Annual Meeting and Exposition on Saturday 5 December 2020.
“These results reinforce the long-term value of fixed-duration, chemotherapy-free Venclexta/Venclyxto-based combinations in CLL, potentially offering patients a significant period of time without treatment following initial therapy,” said Levi Garraway, M.D., Ph.D., Roche’s Chief Medical Officer and Head of Global Product Development. “These data also reflect our ongoing commitment to accelerating clinical advancements for patients by exploring the novel endpoint minimal residual disease as a potential predictor of patient outcomes.”
Five-year data from the pivotal phase III MURANO trial continue to show sustained investigator-assessed progression-free survival (PFS) with Venclexta/Venclyxto plus MabThera®/Rituxan® (rituximab). Data, presented in an oral session, showed:
Data from the phase III CLL14 study contributes to growing evidence regarding the potential of MRD measurements to predict future outcomes for certain people with previously untreated CLL who were treated with fixed-duration Venclexta/Venclyxto plus Gazyva®/Gazyvaro® (obinutuzumab):
Exploring novel endpoints, such as MRD, is an important area of development for Roche, which continues to investigate Venclexta/Venclyxto in a robust clinical development programme. This includes the phase III CRISTALLO trial in previously untreated CLL, which uses MRD as a primary endpoint.
Venclexta/Venclyxto is approved in the US and EU in combination with MabThera/Rituxan for the treatment of adult patients with CLL who have received at least one prior therapy; in combination with Gazyva/Gazyvaro for the treatment of adult patients with previously untreated CLL; and as a monotherapy for the treatment of CLL in the presence of 17p deletion or TP53 mutation in people who are unsuitable for or have failed a B-cell receptor pathway inhibitor.
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, under the brand name Venclexta, and commercialised by AbbVie outside of the US.
*Minimal residual disease (MRD) is a measure of the number of remaining cancer cells. Undetectable MRD (uMRD), sometimes referred to as MRD-negativity, means that no cancer cells could be detected using a specific and highly sensitive test, and is defined as less than one cancer cell in 10,000 leukocytes.
About the MURANO study 4
MURANO [NCT02005471] is a phase III open-label, international, multicentre, randomised study evaluating the efficacy and safety of fixed-duration Venclexta®/Venclyxto® (venetoclax) in combination with MabThera®/Rituxan® (rituximab) compared to bendamustine in combination with MabThera/Rituxan (BR). All treatments were of fixed duration. Following a five-week dose ramp-up schedule for Venclexta/Venclyxto, patients on the Venclexta/Venclyxto plus MabThera/Rituxan arm received six cycles of Venclexta/Venclyxto plus MabThera/Rituxan followed by Venclexta/Venclyxto monotherapy for up to two years total. Patients on the BR arm received six cycles of BR. The study included 389 patients with chronic lymphocytic leukaemia, with or without 17p deletion, who had been previously treated with at least one line of therapy. Patients were randomly assigned in a 1:1 ratio to receive either Venclexta/Venclyxto plus MabThera/Rituxan or BR. The primary endpoint of the study was progression-free survival. Secondary endpoints included overall survival, overall response rate and complete response rate (with or without complete blood count recovery).
About the CLL14 study 5
CLL14 [NCT02242942] is a randomised phase III study evaluating the combination of fixed-duration Venclexta®/Venclyxto® (venetoclax) plus Gazyva®/Gazyvaro® (obinutuzumab) compared to Gazyva/Gazyvaro plus chlorambucil in adult patients with previously untreated chronic lymphocytic leukaemia (CLL) and co-existing medical conditions. 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 burden. The primary endpoint of the study is investigator-assessed progression-free survival (PFS). Secondary endpoints include PFS assessed by independent review committee, minimal residual disease (MRD) status, overall response rate, complete response rate (with or without complete blood count recovery), overall survival, duration of response, event-free survival, time to next CLL treatment, and safety. MRD-negativity, or undetectable MRD, means no cancer can be detected using a specific and highly sensitive test, and was defined as less than one cancer cell in 10,000 leukocytes. The CLL14 study is being conducted in cooperation with the German CLL Study Group, headed by Michael Hallek, MD, University of Cologne.
About Venclexta/Venclyxto (venetoclax)
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 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 commercialised by AbbVie, under the brand name Venclyxto 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.
In the US, Venclexta has been granted five Breakthrough Therapy Designations by the US Food and Drug Administration: one for previously untreated chronic lymphocytic leukaemia (CLL), two for relapsed or refractory CLL and two for previously untreated acute myeloid leukaemia.
About Gazyva/Gazyvaro (obinutuzumab)
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/Gazyvaro is currently approved in more than 90 countries in combination with chlorambucil for people with previously untreated chronic lymphocytic leukaemia, in more than 80 countries in combination with bendamustine for people with certain types of previously treated follicular lymphoma and in more than 70 countries in combination with chemotherapy for previously untreated follicular lymphoma.
Additional combination studies investigating Gazyva/Gazyvaro with other approved or investigational medicines, including cancer immunotherapies and small molecule inhibitors, are underway across a range of blood cancers.
About chronic lymphocytic leukaemia
Chronic lymphocytic leukaemia (CLL) is the most common type of leukaemia in the Western world. 6 CLL mainly affects men and the median age at diagnosis is about 70 years.7 Worldwide, the incidence of all leukaemias is estimated to be over 400,000, with an incidence of over 100,000 in Europe.[8] CLL is estimated to affect around one-third of all people newly diagnosed with leukaemia.6
