With nearly four years of study follow-up, all-oral, fixed-duration IMBRUVICA® (ibrutinib) + venetoclax reduced the risk of progression or death by 79 percent and demonstrated overall survival (OS) advantage versus chemoimmunotherapy1
BEERSE, BELGIUM, Dec. 10, 2022 (GLOBE NEWSWIRE) — The Janssen Pharmaceutical Companies of Johnson & Johnson today announced new four-year follow-up results from the Phase 3 GLOW study (Abstract #93),1 which showed fixed-duration treatment with IMBRUVICA® (ibrutinib) + venetoclax (I+V) reduced the risk of progression or death by 79 percent among older and/or unfit patients with previously untreated chronic lymphocytic leukaemia (CLL) compared to patients treated with chlorambucil plus obinutuzumab (Clb+O).1 These results were highlighted in an oral presentation during the 2022 American Society of Hematology (ASH) Annual Meeting, taking place in New Orleans, U.S.1
CLL is the most common form of leukaemia in the Western world and currently has no cure.2,3 While the treatment landscape has evolved significantly since the emergence of targeted agents,4 there is still significant unmet need for novel treatment options, including fixed-duration regimens.5
“The GLOW study results demonstrate the potential of fixed-duration I+V as an additional treatment option for older, unfit patients with CLL in the first-line setting, and this fixed-dose combination may offer a flexible regimen for patients seeking a time-limited treatment approach,” said study investigator Carsten Niemann,† M.D., Ph.D., Clinical Associate Professor and Principal Investigator at Rigshospitalet, Copenhagen, Denmark. “This first all-oral, fixed-duration novel combination demonstrates an OS advantage in the first-line treatment of CLL and is an innovative option for patients.”
In the study, fixed-duration I+V therapy exhibited robust efficacy in older and/or unfit adults with previously untreated CLL, with a superior and sustained benefit in progression-free survival (PFS) with four years of follow-up.1 Seventy-five percent of patients treated with the combination were alive and progression-free at 3.5 years.1 I+V also demonstrated an OS advantage versus Clb+O at this latest study follow-up.1 Exploratory analyses showed that post-treatment PFS rates were higher for I+V (n=106) than Clb+O (n=105), regardless of minimal residual disease (MRD) status post-treatment.1
“In the GLOW study, two highly active blood cancer treatments have been combined in a novel, all-oral, fixed-duration combination to deliver superior progression-free survival and an overall survival advantage versus chlorambucil plus obinutuzumab in the first-line treatment of CLL,” said Edmond Chan, MBChB, M.D. (Res), EMEA Therapeutic Area Lead Haematology, Janssen-Cilag Limited. “These latest results at ASH reinforce our ongoing commitment to developing innovations that not only improve patient outcomes but also provide greater flexibility, so healthcare professionals have the option to tailor ibrutinib-based regimens to best suit patients’ needs and preferences.”
Updated data showed the safety profile of the I+V regimen was consistent with the known safety profiles of ibrutinib and venetoclax.
“Ibrutinib has helped change the standard of care for adults living with CLL and other B-cell malignancies, and this study adds to the extensive body of evidence supporting its potential to provide improved survival for patients with CLL,” said Craig Tendler, M.D., Vice President, Late Development and Global Medical Affairs, Janssen Research & Development, LLC. “At Janssen, we are committed to addressing the unmet needs of patients with CLL through continued investment in our ibrutinib clinical development programme.”
In addition to the GLOW results, data from the Phase 2 CAPTIVATE study of the MRD cohort (PCYC-1142) (Abstract #92), which utilised the same I+V schedule for the first 15 cycles as in the GLOW study, were also presented in the same oral session at ASH 2022.7 After the first 15 cycles, patients with confirmed uMRD (n=86) were randomised to ibrutinib or placebo. Disease-free survival at three years post-randomisation was 93 percent for ibrutinib and 85 percent for placebo. PFS rates at four years from start of treatment were 95 percent and 88 percent, respectively, and OS rates were 98 percent and 100 percent.7
During the three-year post-randomisation period in CAPTIVATE, no new atrial fibrillation events occurred in the placebo arm, and no new grade three or higher haemorrhage events occurred in either arm. The incidences of hypertension, arthralgia, neutropenia and diarrhoea were generally infrequent in the placebo arm during this time period.7 No deaths occurred in either arm during the last 12 months of follow-up.7
In August 2022, the European Commission granted marketing authorisation for the expanded use of ibrutinib in combination with venetoclax for adults with previously untreated CLL.8 The approval is based on the Phase 3 GLOW and Phase 2 CAPTIVATE studies.
About the GLOW study
The Phase 3 GLOW study (n=211; median age, 71 years) is a randomised, open-label trial which evaluated the efficacy and safety of first-line, fixed-duration I+V vs. Clb+O in elderly patients (≥65 years of age) with CLL/SLL, or patients aged 18-64 with a cumulative illness rating scale (CIRS) score of greater than six or creatinine clearance less than 70 mL/min, without del(17p) or known TP53 mutations.9 Patients in the study were randomised to receive either 3 cycles of ibrutinib lead-in, followed by 12 cycles of I+V (n=106), or 6 cycles of Clb+O (n=105).5
Among patients with partial response or better, MRD in peripheral blood (PB) was evaluated using next-generation sequencing (NGS) via clonoSEQ on-treatment and at 3-6 month intervals posttreatment.5 ClonoSEQ data was used as part of CLL clonal testing.5
The primary endpoint is PFS assessed by an independent review committee. Secondary endpoints of the study include MRD negative rate, complete response rate, overall response rate, OS, duration of response, and time-to-next treatment.5
About the CAPTIVATE study
The Phase 2 CAPTIVATE study evaluated previously untreated adult patients with CLL who were 70 years or younger, including patients with high-risk disease, in two cohorts: an MRD-guided cohort (n=164; median age, 58 years) and a fixed-duration cohort (n=159; median age, 60 years).10 Patients in the MRD cohort received 3 cycles of ibrutinib lead-in followed by 12 cycles of I+V (oral ibrutinib [420 mg/d]; oral venetoclax [5-week ramp-up to 400 mg/d]).10 Patients who met the stringent random assignment criteria for confirmed undetectable MRD (uMRD) were randomly assigned 1:1 to double-blind placebo or ibrutinib; patients without confirmed uMRD were randomly assigned 1:1 to open-label ibrutinib or ibrutinib plus venetoclax.10 The primary endpoint was 1-year disease-free survival rate in the confirmed uMRD population.7
Ibrutinib is a once-daily oral medication that is jointly developed and commercialised by Janssen Biotech, Inc. and Pharmacyclics LLC, an AbbVie company.11 Ibrutinib blocks the Bruton’s tyrosine kinase (BTK) protein, which is needed by normal and abnormal B-cells, including specific cancer cells, to multiply and spread.12 By blocking BTK, ibrutinib may help move abnormal B-cells out of their nourishing environments and inhibits their proliferation.13
Ibrutinib is approved in more than 100 countries and has been used to treat more than 270,000 patients worldwide.14 There are more than 50 company-sponsored clinical trials, including 18 Phase 3 studies, over 11 years evaluating the efficacy and safety of ibrutinib.11,15 In October 2021, ibrutinib was added to the World Health Organization’s Model Lists of Essential Medicines (EML), which refers to medicines that address global health priorities and which should be available and affordable for all.16
Ibrutinib was first approved by the European Commission (EC) in 2014, and approved indications to date include:11

About Chronic Lymphocytic Leukaemia
Chronic lymphocytic leukaemia (CLL) is typically a slow-growing blood cancer of the white blood cells.17 The overall incidence of CLL in Europe is approximately 4.92 cases per 100,000 persons per year and it is about 1.5 times more common in men than in women.18 CLL is predominantly a disease of the elderly, with a median age of 72 years at diagnosis.19
While patient outcomes have dramatically improved in the last few decades, the disease is still characterised by consecutive episodes of disease progression and the need for therapy.4 Patients are often prescribed multiple lines of therapy as they relapse or become resistant to treatments.20
