Calquence significantly prolonged the time patients lived
without disease progression in relapsed or refractory chronic
lymphocytic leukaemia
An encouraging 88% of patients on Calquence remained free of
disease progression after 12 months, vs. 68% of patients on
rituximab combined with idelalisib or bendamustine
AstraZeneca today announced detailed results from the interim
analysis of the Phase III ASC trial at the European Hematology
Association (EHA) Annual Congress in Amsterdam, showing Calquence
(acalabrutinib) significantly prolonged the time patients live
without disease progression in relapsed or refractory chronic
lymphocytic leukaemia (CLL).
The ASC trial compared Calquence with the physician's choice of
rituximab combined with idelalisib (IdR) or bendamustine (BR) in
patients with relapsed or refractory CLL.
At a median follow-up of 16.1 months, results from the trial
showed a statistically-significant and clinically-meaningful
improvement in progression-free survival (PFS) for patients treated
with Calquence vs. IdR or BR, reducing the risk of disease
progression or death by 69% (HR, 0.31; 95% CI, 0.20-0.49,
p<0.0001). The median time without disease progression for
patients treated with Calquence has not yet been reached vs. 16.5
months in the control arm. At 12 months, 88% of patients on
Calquence showed no disease progression compared to 68% for the
control arm. The safety and tolerability of Calquence was
consistent with its established profile.
José Baselga, Executive Vice President, Oncology R&D said:
"These data add to the growing body of evidence to support the
profile of Calquence as a selective BTK inhibitor that offers a
chemotherapy-free treatment option with a favourable safety profile
in chronic lymphocytic leukaemia, a life-threatening disease. These
data, along with our recent positive results from the Phase III
ELEVATE-TN trial in previously-untreated chronic lymphocytic
leukaemia, will serve as the foundation for regulatory submissions
later this year."
Paolo Ghia, MD, Professor, Medical Oncology, Università
Vita-Salute San Raffaele in Milan, and investigator of the ASC
trial, said: "This is the first randomised trial to directly
compare a BTK inhibitor as monotherapy with standard
chemoimmunotherapy or idelalisib and rituximab combinations. With a
significant improvement in progression-free survival and a
favourable safety profile, acalabrutinib may become an important
choice for the treatment of patients with relapsed or refractory
chronic lymphocytic leukaemia."

AstraZeneca recently announced that the Phase III ELEVATE-TN
trial met its primary endpoint at interim analysis in patients with
previously-untreated CLL and that full results will be reported at
a forthcoming medical meeting. Calquence is currently approved for
the treatment of adults with relapsed or refractory mantle cell
lymphoma (MCL) in the US, Brazil, the United Arab Emirates, and
Qatar and is being developed for the treatment of CLL and other
blood cancers.
About ASC
ASC (ACE-CL-309) is a global, randomised, multicentre,
open-label Phase III trial evaluating the efficacy of Calquence in
previously-treated patients with CLL.(2) In the trial, 310 patients
were randomised (1:1) into two arms. Patients in the first arm
received Calquence monotherapy (100mg twice daily until disease
progression). Patients in the second arm received physician's
choice of either rituximab in combination with idelalisib or
rituximab in combination with bendamustine.(1,2)
The primary endpoint is PFS assessed by an independent review
committee (IRC), and key secondary endpoints include
physician-assessed PFS, IRC- and physician-assessed overall
response rate (ORR) and duration of response (DoR), as well as
overall survival (OS), patient reported outcomes (PROs) and time to
next treatment (TTNT).(1,2)
About Calquence
Calquence (acalabrutinib) was granted accelerated approval by
the US Food and Drug Administration (FDA) in October 2017 for the
treatment of adult patients with MCL who have received at least one
prior therapy. Continued approval for this indication may be
contingent upon verification and description of clinical benefit in
confirmatory trials.
Calquence is an inhibitor of Bruton tyrosine kinase (BTK).
Calquence binds covalently to BTK, thereby inhibiting its
activity.(3) In B-cells, BTK signalling results in activation of
pathways necessary for B-cell proliferation, trafficking,
chemotaxis, and adhesion.
As part of an extensive clinical development programme,
AstraZeneca and Acerta Pharma are currently evaluating Calquence in
26 company-sponsored clinical trials. Calquence is being developed
for the treatment of multiple B-cell blood cancers including CLL,
MCL, diffuse large B-cell lymphoma, Waldenstrom macroglobulinaemia,
follicular lymphoma, and multiple myeloma and other haematologic
malignancies. Beyond the positive Phase III trials ASC and
ELEVATE-TN, other Phase III trials in CLL are ongoing, including
ELEVATE-RR (ACE-CL-006) evaluating acalabrutinib vs. ibrutinib in
patients with previously-treated high-risk CLL, and ACE-CL-311
evaluating acalabrutinib in combination with venetoclax and
with/without obinutuzumab in patients with previously-untreated CLL
without 17p deletion or TP53 mutation.
About chronic lymphocytic leukaemia
Chronic lymphocytic leukaemia (CLL) is the most common type of
leukaemia in adults, with an estimated 191,000 new cases globally
and 20,720 new cases in the US annually, and prevalence that is
expected to grow with improved treatment.(4-7) In CLL, too many
blood stem cells in the bone marrow become abnormal lymphocytes and
these abnormal cells have difficulty fighting infections.(4) As the
number of abnormal cells grows there is less room for healthy white
blood cells, red blood cells and platelets.(4) This could result in
anaemia, infection and bleeding.(4) B-cell receptor signalling
through BTK is one of the essential growth pathways for CLL.
About AstraZeneca in haematology
Leveraging its strength in oncology, AstraZeneca has established
haematology as one of four key oncology disease areas of focus. The
Company's haematology franchise includes two US FDA-approved
medicines and a robust global development programme for a broad

serves as AstraZeneca's haematology research and development arm.
AstraZeneca partners with like-minded science-led companies to
advance the discovery and development of therapies to address unmet
need.
In October 2018, AstraZeneca and Innate Pharma announced a
global strategic collaboration that included Innate Pharma
licensing the US commercial rights of Lumoxiti (moxetumomab
pasudotox-tdfk), and with support from AstraZeneca, will continue
EU development and commercialisation, pending regulatory submission
and approval.
