Ibrutinib RESONATE(TM) Data Show Significant Improvements in Progression-Free 
Survival and Overall Survival in Patients with Chronic Lymphocytic Leukemia or 
Small Lymphocytic Lymphoma 
Phase 3 data featured in the official press program of the 50(th) annual 
meeting of the American Society of Clinical Oncology and simultaneously 
published in the New England Journal of Medicine 
TORONTO, June 2, 2014 /CNW/ - Data from the international, multicenter Phase 3 
RESONATE(TM) trial show single-agent ibrutinib, a targeted therapy, 
significantly lengthened progression-free survival (PFS) and overall survival 
(OS) in patients with relapsed or refractory chronic lymphocytic leukemia 
(CLL) or small lymphocytic lymphoma (SLL).  Janssen Inc. announced today that 
these data were presented during the official press program at the American 
Society of Clinical Oncology (ASCO) meeting in Chicago, IL and they were 
simultaneously published in a special edition of The New England Journal of 
Medicine. 
The results from the RESONATE(TM) study show ibrutinib significantly improved 
PFS (median not reached vs. 8.1 months; HR 0.215, 95% CI, 0.146 to 0.317; 
P<0.0001) and OS (HR 0.434; 95% CI, 0.238 to 0.789; P=0.0049) compared to 
ofatumumab. The median PFS in the ibrutinib arm was not reached because of a 
lower rate of progression events than in the ofatumumab arm. These PFS results 
represent a 79 per cent reduction in the risk of disease progression or death 
from any cause in patients treated with ibrutinib compared to ofatumumab. The 
OS results represent a 57 per cent reduction in the risk of death in patients 
receiving ibrutinib compared to ofatumumab. Additionally, the overall response 
rate (ORR) was significantly higher in patients taking ibrutinib versus 
ofatumumab. Forty-three per cent of ibrutinib patients achieved a partial 
response (PR) compared to only four per cent of patients taking ofatumumab 
(p<0.0001). Consistent results were seen in CLL/SLL patients with a deletion 
in the short arm of chromosome 17 (del 17p), a genetic mutation typically 
associated with poor prognosis.(1) 
"The RESONATE data are particularly exciting for clinicians in Canada as they 
show a significant improvement in progression-free and overall survival in 
patients with relapsed or refractory CLL compared with our current 
treatments," said Dr. Cynthia Toze, Member, Leukemia/BMT Program of British 
Columbia, Clinical Professor of Medicine, UBC. "The results demonstrate that 
ibrutinib, as a targeted therapy, is an effective and tolerable treatment 
option for patients with CLL who have relapsed or whose disease did not 
respond to first-line treatment.  Moreover, this drug has shown effectiveness 
in the poor risk population of patients with CLL who have deletion 11q or 17p, 
comprising over 60 per cent of patients in the RESONATE trial."* 
About RESONATE(TM) 
RESONATE(TM) is a Phase 3, multi-center, international, open-label, randomized 
study that examined ibrutinib versus ofatumumab in relapsed or refractory 
patients with CLL/SLL who had received at least one prior therapy and were not 
considered appropriate candidates for treatment with purine analog-based 
therapy (n=391). Patients were administered either 420 mg oral ibrutinib 
(n=195) daily until progression or unacceptable toxicity or intravenous 
ofatumumab for up to 24 weeks (n=196, initial dose of 300 mg followed by 11 
doses at 2,000 mg; dose and schedule consistent with local labeling). 
Progression-free survival is the primary endpoint of the RESONATE(TM) study, 
with OS, ORR and safety as key secondary endpoints. The median follow-up was 
9.4 months. 
In January 2014, RESONATE(TM) was stopped early at the unanimous 
recommendation of an Independent Data Monitoring Committee (IDMC) based on a 
planned interim analysis which concluded that the study showed a significant 
difference in PFS as compared to the control (the primary endpoint of the 
study). The IDMC recommended that the sponsor provide access to ibrutinib to 
patients in the ofatumumab arm. 
The most common Grade 3 or 4 adverse events (AEs) in the RESONATE(TM) trial 
(occurring in five per cent or more of patients) were neutropenia (decreased 
amount of neutrophils in the blood; 16 per cent in the ibrutinib arm vs. 14 
per cent in the ofatumumab arm), pneumonia (seven per cent vs. five per cent), 
thrombocytopenia (decrease in platelets in the blood; six per cent vs. four 
per cent) and anemia (five per cent vs. eight per cent). The most commonly 
occurring side effects (AEs in 20 per cent or more of patients) were diarrhea 
(48 per cent vs.18 per cent), fatigue (28 per cent vs. 30 per cent), pyrexia 
(fever; 24 per cent vs. 15 per cent), nausea (26 per cent vs.18 per cent), 
anemia (23 per cent vs. 17 per cent) and neutropenia (21 per cent vs. 15 per 
cent). Atrial fibrillation of any grade was noted more frequently in patients 
receiving ibrutinib (n=10 patients) versus ofatumumab (n=1 patient). Total 
treatment exposure was longer for the ibrutinib arm than the ofatumumab arm 
(median time: 8.6 months vs. 5.3 months). 
Treatment discontinuations due to progressive disease were five per cent in 
the ibrutinib arm and 19 per cent in the ofatumumab arm. Four per cent of 
patients in both treatment arms (eight patients in the ibrutinib arm and seven 
patients in the ofatumumab arm) discontinued treatment due to adverse events 
in the clinical trial. Treatment discontinuation due to death occurred in four 
per cent of patients in the ibrutinib arm (eight patients) and five per cent 
of patients in the ofatumumab arm (nine patients). These events were most 
commonly infectious in nature. 
About CLL and SLL 
Chronic lymphocytic leukemia is a slow-growing blood cancer of white blood 
cells called lymphocytes, most commonly B cells.(([1])) Chronic lymphocytic 
leukemia is the most common type of leukemia in adults, and is more common in 
older adults over 60.[2] In Canada, it is estimated that about 2,400 adults 
were diagnosed with CLL in 2010.(2) The disease often eventually progresses; 
patients are faced with fewer treatment options and are often prescribed 
multiple lines of therapy as they relapse or become resistant to 
treatments.(([3]))( )Small lymphocytic leukemia is a slow-growing lymphoma in 
which too many immature white blood cells cause lymph nodes to become larger 
than normal.(1) 
About Ibrutinib 
Ibrutinib works by blocking a specific protein called Bruton's tyrosine kinase 
(BTK).(4) The BTK protein transmits important signals that tell B cells to 
mature and produce antibodies, and is needed by specific cancer cells to 
multiply and spread. [4](,[5]) Ibrutinib targets and blocks BTK, inhibiting 
the spread and survival of cancer cells.(4) 
Ibrutinib received U.S. approval via the FDA's Breakthrough Therapy 
Designation and is indicated for the treatment of patients with CLL who have 
received at least one prior therapy, and for the treatment of patients with 
mantle cell lymphoma (MCL) who have received at least one prior therapy. 
Ibrutinib is undergoing priority review at Health Canada in the area of CLL. 
Ibrutinib is being jointly developed and commercialized by Janssen Biotech, 
Inc. and Pharmacyclics, Inc.
