First data presentation of CALQUENCE®, (acalabrutinib), recently approved in the US for patients with previously-treated mantle cell lymphoma
New data on five compounds in development across six types of blood cancer
AstraZeneca, along with Acerta Pharma, its hematology research and development center of excellence, and MedImmune, its global biologics research and development arm, will highlight significant progress in blood cancer research at the 59th 2017 American Society of Hematology (ASH) Annual Meeting & Exhibition in Atlanta. Presentations will include new data from AstraZeneca’s emerging hematology portfolio in several cancer types including mantle cell lymphoma (MCL), chronic lymphocytic leukemia (CLL), hairy cell leukemia (HCL), acute myeloid leukemia (AML), multiple myeloma and diffuse large B-cell lymphoma (DLBCL).
Sean Bohen, Executive Vice President, Global Medicines Development and Chief Medical Officer at AstraZeneca, said: “Following the recent accelerated approval of AstraZeneca’s first medicine for a blood cancer, CALQUENCE, we will share a broad range of new data at ASH highlighting our scientific progress in hematology as we seek to develop potential medicines that advance patient care.”
CALQUENCE (acalabrutinib) is a kinase inhibitor indicated for the treatment of adult patients with mantle cell lymphoma (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.
Efficacy and safety of CALQUENCE in treatment of previously-treated MCL
Following the US Food and Drug Administration (FDA) accelerated approval of CALQUENCE, data from the pivotal Phase II ACE-LY-004 clinical trial on which the accelerated approval was based, will be presented for the first time (Abstract #155). New details of the trial will be shared, including median time to response, pre-specified patient subgroup efficacy analyses, as well as safety analyses, further characterizing the clinical profile of CALQUENCE in this patient population.
Acalabrutinib as monotherapy and in combination in multiple CLL patient populations
Results will be presented from the Phase Ib/II ACE-CL-003 trial evaluating acalabrutinib and obinutuzumab in treatment-naïve and previously-treated CLL patients (Abstract #432), which highlight data on the safety profile and activity of the combination. Long-term follow-up safety and efficacy data from the Phase I/II ACE-CL-001 clinical trial which is testing acalabrutinib as a monotherapy in a large cohort of patients with relapsed or refractory CLL (Abstract #498) will expand on findings previously reported; these data will also highlight the duration of response in this patient population.
Early-stage hematology portfolio
- AstraZeneca will present additional data from its haematology portfolio, including findings from a Phase I trial of moxetumomab pasudotox, an anti-CD22 recombinant immunotoxin and potential new medicine in development for the treatment of people with previously-treated HCL (Abstract: #2765)
- Early data on AZD2811, a novel nanoparticle inhibitor of aurora kinase B being tested in AML (Abstract #1368)
- Preclinical data from trials on MEDI2228, a BCMA-targeting pyrrolobenzodiazepine-linked antibody drug conjugate being tested in multiple myeloma (Abstract #3153)
- Data from a trial of vistusertib (AZD2014), a dual mTORC1/2 inhibitor being tested in DLBCL (Abstract #4113)
IMPORTANT SAFETY INFORMATION ABOUT CALQUENCE
Serious hemorrhagic events, including fatal events, have occurred in the combined safety database of 612 patients with hematologic malignancies treated with CALQUENCE monotherapy. Grade 3 or higher bleeding events, including gastrointestinal, intracranial, and epistaxis, have been reported in 2% of patients. Overall, bleeding events, including bruising and petechiae of any grade, occurred in approximately 50% of patients with hematological malignancies.
The mechanism for the bleeding events is not well understood.
CALQUENCE may further increase the risk of hemorrhage in patients receiving antiplatelet or anticoagulant therapies, and patients should be monitored for signs of bleeding.
Consider the benefit-risk of withholding CALQUENCE for 3 to 7 days pre- and post-surgery, depending upon the type of surgery and the risk of bleeding.
Serious infections (bacterial, viral, or fungal), including fatal events and opportunistic infections, have occurred in the combined safety database of 612 patients with hematologic malignancies treated with CALQUENCE monotherapy. Grade 3 or higher infections occurred in 18% of these patients. The most frequently reported Grade 3 or 4 infection was pneumonia. Infections due to hepatitis B virus (HBV) reactivation and progressive multifocal leukoencephalopathy (PML) have occurred.
Monitor patients for signs and symptoms of infection and treat as medically appropriate. Consider prophylaxis in patients who are at increased risk for opportunistic infections.
In the combined safety database of 612 patients with hematologic malignancies, patients treated with CALQUENCE monotherapy experienced Grade 3 or 4 cytopenias, including neutropenia (23%), anemia (11%), and thrombocytopenia (8%), based on laboratory measurements. Monitor complete blood counts monthly during treatment.
Second Primary Malignancies
Second primary malignancies, including non-skin carcinomas, have occurred in 11% of patients with hematologic malignancies treated with CALQUENCE monotherapy in the combined safety database of 612 patients. The most frequent second primary malignancy was skin cancer, reported in 7% of patients. Advise protection from sun exposure.
Atrial Fibrillation and Flutter
In the combined safety database of 612 patients with hematologic malignancies treated with CALQUENCE monotherapy, atrial fibrillation and atrial flutter of any grade occurred in 3% of patients, and Grade 3 in 1% of patients. Monitor for atrial fibrillation and atrial flutter and manage as appropriate.
The most common adverse reactions (≥20%) of any grade were anemia,* thrombocytopenia,* headache (39%), neutropenia,* diarrhea (31%), fatigue (28%), myalgia (21%), and bruising (21%).
*Treatment-emergent decreases (all grades) of hemoglobin (46%), platelets (44%), and neutrophils (36%) were based on laboratory measurements and adverse reactions.
The most common Grade ≥ 3 non-hematological adverse reaction (reported in at least 2% of patients) was diarrhea (3.2%).
Dosage reductions or discontinuations due to any adverse reaction were reported in 1.6% and 6.5% of patients, respectively.
Increases in creatinine 1.5 to 3 times the upper limit of normal occurred in 4.8% of patients.
Strong CYP3A Inhibitors: Avoid co-administration with a strong CYP3A inhibitor. If a strong CYP3A inhibitor will be used short-term, interrupt CALQUENCE.
Moderate CYP3A Inhibitors: When CALQUENCE is co-administered with a moderate CYP3A inhibitor, reduce CALQUENCE dose to 100 mg once daily.
Strong CYP3A Inducers: Avoid co-administration with a strong CYP3A inducer. If a strong CYP3A inducer cannot be avoided, increase the CALQUENCE dose to 200 mg twice daily.
Gastric Acid Reducing Agents: If treatment with a gastric acid reducing agent is required, consider using an H2-receptor antagonist or an antacid. Take CALQUENCE 2 hours before taking an H2-receptor antagonist. Separate dosing with an antacid by at least 2 hours.
Avoid co-administration with proton pump inhibitors. Due to the long-lasting effect of proton pump inhibitors, separation of doses may not eliminate the interaction with CALQUENCE.
There is insufficient clinical data on CALQUENCE use in pregnant women to inform a drug-associated risk for major birth defects and miscarriage. Advise women of the potential risk to a fetus.
It is not known if CALQUENCE is present in human milk. Advise lactating women not to breastfeed while taking CALQUENCE and for at least 2 weeks after the final dose.
