CALQUENCE ® ( acalabrutinib ) capsules , for oral use Initial U . S . Approval : 2017
Brief Summary of Prescribing Information . For complete prescribing information consult official package insert .
INDICATIONS AND USAGE CALQUENCE is indicated for the treatment of adult patients with mantle cell lymphoma ( MCL ) who have received at least one prior therapy .
This indication is approved under accelerated approval based on overall response rate [ see Clinical Studies ( 14 ) in the full Prescribing Information ]. Continued approval for this indication may be contingent upon verification and description of clinical benefit in confirmatory trials .
DOSAGE AND ADMINISTRATION
Recommended Dosage The recommended dose of CALQUENCE is 100 mg taken orally approximately every twelve hours until disease progression or unacceptable toxicity .
Advise patients to swallow capsule whole with water . Advise patients not to open , break or chew the capsules . CALQUENCE may be taken with or without food . If a dose of CALQUENCE is missed by more than 3 hours , it should be skipped and the next dose should be taken at its regularly scheduled time . Extra capsules of CALQUENCE should not be taken to make up for a missed dose .
Dose Modifications
Adverse Reactions Recommended dose modifications of CALQUENCE for Grade 3 or greater adverse reactions are provided in Table 1 .

Dose Modifications for Use with CYP3A Inhibitors or Inducers
Recommended dose modifications are described below [ see Drug Interactions ( 7 ) in the full
Prescribing Information ].
CYP3A
Co-administered Drug
Recommended CALQUENCE use
Inhibition
Strong CYP3A inhibitor
Avoid concomitant use .
If these inhibitors will be used short-term
( such as anti-infectives for up to seven days ), interrupt CALQUENCE .
Moderate CYP3A inhibitor
100 mg once daily .
Induction
Strong CYP3A inducer
Avoid concomitant use .
If these inducers cannot be avoided , increase CALQUENCE dose to 200 mg twice daily .
Concomitant Use with Gastric Acid Reducing Agents Proton Pump Inhibitors : Avoid concomitant use [ see Drug Interactions ( 7 ) in the full Prescribing Information ].
H2-Receptor Antagonists : Take CALQUENCE 2 hours before taking a H2-receptor antagonist [ see Drug Interactions ( 7 ) in the full Prescribing Information ].

WARNINGS AND PRECAUTIONS
Hemorrhage 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 3-7 days pre- and post-surgery depending upon the type of surgery and the risk of bleeding .
Infection 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 . Consider prophylaxis in patients who are at increased risk for opportunistic infections .
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 .
Cytopenias 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 . In the CALQUENCE clinical Trial LY-004 , patients ’ complete blood counts were assessed 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 .
ADVERSE REACTIONS The following adverse reactions are discussed in greater detail in other sections of the labeling :
• Hemorrhage [ see Warnings and Precautions ( 5.1 ) in the full Prescribing Information ]
• Infection [ see Warnings and Precautions ( 5.2 ) in the full Prescribing Information ]
• Cytopenias [ see Warnings and Precautions ( 5.3 ) in the full Prescribing Information ]
• Second Primary Malignancies [ see Warnings and Precautions ( 5.4 ) in the full Prescribing Information ]
• Atrial Fibrillation and Flutter [ see Warnings and Precautions ( 5.5 ) in the full Prescribing Information ]
Clinical Trials Experience As clinical trials are conducted under widely varying conditions , adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice .
The safety data described in this section reflect exposure to CALQUENCE ( 100 mg twice daily ) in 124 patients with previously treated MCL in Trial LY-004 [ see Clinical Studies ( 14 ) in the full Prescribing Information ]. The median duration of treatment with CALQUENCE was 16.6 ( range 0.1 to 26.6 ) months . A total of 91 ( 73.4 %) patients were treated with CALQUENCE for ≥ 6 months and 74 ( 59.7 %) patients were treated for ≥ 1 year .
The most common adverse reactions ( ≥ 20 %) of any grade were anemia , thrombocytopenia , headache , neutropenia , diarrhea , fatigue , myalgia , and bruising . Grade 1 severity for the non-hematologic , most common events were as follows : headache ( 25 %), diarrhea ( 16 %), fatigue ( 20 %), myalgia ( 15 %), and bruising ( 19 %). The most common Grade ≥ 3 non-hematological adverse reaction ( reported in at least 2 % of patients ) was diarrhea .
Dose reductions or discontinuation due to any adverse reaction were reported in 1.6 % and 6.5 % of patients , respectively .
Tables 2 and 3 present the frequency category of adverse reactions observed in patients with MCL treated with CALQUENCE .
