Function and Efficacy

Acalabrutinib is a small-molecule inhibitor of Bruton tyrosine kinase (BTK). Acalabrutinib and its active metabolite, ACP-5862, form a covalent bond with a cysteine residue in the BTK active site, leading to inhibition of BTK enzymatic activity. BTK is a signaling molecule of the B cell antigen receptor (BCR) and cytokine receptor pathways. In B cells, BTK signaling results in activation of pathways necessary for B-cell proliferation, trafficking, chemotaxis, and adhesion. In nonclinical studies, acalabrutinib inhibited BTK‑mediated activation of downstream signaling proteins CD86 and CD69 and inhibited malignant B-cell proliferation and tumor growth in mouse xenograft models. In patients with B-cell malignancies dosed with acalabrutinib 100 mg approximately every 12 hours, median steady state BTK occupancy of >= 95% in peripheral blood was maintained over 12 hours, resulting in inactivation of BTK throughout the recommended dosing interval. Cardiac Electrophysiology At a dose 4 times the approved recommended dosage, CALQUENCE does not prolong the QTc interval to any clinically relevant extent. Acalabrutinib and its active metabolite, ACP-5862, exposures increase proportionally with dose across a dose range of 75 to 250 mg (0. 5 times the approved recommended single dosage) in patients with B-cell malignancies. At the recommended dose of 100 mg twice daily, the geometric mean (% coefficient of variation [CV]) daily area under the plasma drug concentration over time curve (AUC 24h max Absorption The geometric mean absolute bioavailability of acalabrutinib was 25%. Median (min, max) time to peak plasma concentration (T max Effect of Food In healthy subjects, administration of a single 100 mg dose of acalabrutinib with a high-fat, high-calorie meal (approximately 918 calories, 59 grams carbohydrate, 59 grams fat, and 39 grams protein) did not affect the mean AUC as compared to dosing under fasted conditions. Resulting C max max Distribution The geometric mean (% CV) steady-state volume of distribution (V ss Elimination The geometric mean (% CV) terminal elimination half-life (t 1/2 Metabolism Acalabrutinib is predominantly metabolized by CYP3A enzymes, and to a minor extent, by glutathione conjugation and amide hydrolysis, based on in vitro studies. ACP-5862 was identified as the major active metabolite in plasma with a geometric mean exposure (AUC) that was approximately 2- to 3-fold higher than the exposure of acalabrutinib. ACP-5862 is approximately 50% less potent than acalabrutinib with regard to BTK inhibition. Excretion Following administration of a single 100 mg radiolabeled acalabrutinib dose in healthy subjects, 84% of the dose was recovered in the feces (< 2% unchanged) and 12% of the dose was recovered in the urine (< 2% unchanged). Specific Populations There were no clinically significant differences in the pharmacokinetics of acalabrutinib and its active metabolite, ACP‑5862, based on age (32 to 90 years), sex, race (Caucasian, African American), body weight (40 to 149 kg), or mild to moderate renal impairment (eGFR >= 30 mL/min/1. 73m 2 2 2 Patients with Hepatic Impairment The AUC of acalabrutinib increased 1. 9-fold in subjects with mild hepatic impairment (Child-Pugh class A), 1. 5-fold in subjects with moderate hepatic impairment (Child-Pugh class B) and 5. 3-fold in subjects with severe hepatic impairment (Child-Pugh class C) compared to subjects with normal liver function. No clinically relevant PK difference in ACP-5862 was observed in subjects with severe hepatic impairment (Child-Pugh Class C) compared to subjects with normal liver function. No clinically relevant PK differences in acalabrutinib and ACP-5862 were observed in patients with mild or moderate hepatic impairment (total bilirubin less and equal to upper limit of normal [ULN] and AST greater than ULN, or total bilirubin greater than ULN and any AST) relative to patients with normal hepatic function (total bilirubin and AST within ULN).

Chronic Lymphocytic Leukemia The safety data described below reflect exposure to CALQUENCE (100 mg approximately every 12 hours, with or without obinutuzumab) in 511 patients with CLL from two randomized controlled clinical trials [see Clinical Studies (14. 3) The most common adverse reactions (>= 30%) of any grade in patients with CLL were anemia, neutropenia, thrombocytopenia, headache, upper respiratory tract infection, and diarrhea. ELEVATE-TN The safety of CALQUENCE plus obinutuzumab (CALQUENCE+G), CALQUENCE monotherapy, and obinutuzumab plus chlorambucil (GClb) was evaluated in a randomized, multicenter, open-label, actively controlled trial in 526 patients with previously untreated CLL [see Clinical Studies (14. 3)] Patients randomized to the CALQUENCE+G arm were treated with CALQUENCE and obinutuzumab in combination for six cycles, then with CALQUENCE as monotherapy until disease progression or unacceptable toxicity. Patients initiated obinutuzumab on Day 1 of Cycle 2, continuing for a total of 6 cycles. Patient randomized to CALQUENCE monotherapy received CALQUENCE approximately every 12 hours until disease progression or unacceptable toxicity. The trial required age >= 65 years of age or 18 to 6 or creatinine clearance of 30 to 69 mL/min, hepatic transaminases <= 3 times ULN and total bilirubin <= 1. 5 times ULN, and allowed patients to receive antithrombotic agents other than warfarin or equivalent vitamin K antagonists. During randomized treatment, the median duration of exposure to CALQUENCE in the CALQUENCE+G and CALQUENCE monotherapy arms was 27. 7 months (range 0. 3 to 40 months), with 95% and 92% and 89% and 86% of patients with at least 6 months and 12 months of exposure, respectively. In the obinutuzumab and chlorambucil arm the median number of cycles was 6 with 84% of patients receiving at least 6 cycles of obinutuzumab, 70% of patients received at least 6 cycles of chlorambucil. Eighty-five percent of patients in the CALQUENCE+G arm received at least 6 cycles of obinutuzumab. In the CALQUENCE+G and CALQUENCE monotherapy arms, fatal adverse reactions that occurred in the absence of disease progression and with onset within 30 days of the last study treatment were reported in 2% for each treatment arm, most often from infection. Serious adverse reactions were reported in 39% of patients in the CALQUENCE+G arm and 32% in the CALQUENCE monotherapy arm, most often due to events of pneumonia (2. In the CALQUENCE+G arm, adverse reactions led to treatment discontinuation in 11% of patients and a dose reduction of CALQUENCE in 7% of patients. In the CALQUENCE monotherapy arm, adverse reactions led to discontinuation in 10% and dose reduction in 4% of patients.

ASCEND The safety of CALQUENCE in patients with relapsed or refractory CLL was evaluated in a randomized, open-label study (ASCEND) [see Clinical Studies (14. 3) ] In ASCEND, 154 patients received CALQUENCE (100 mg approximately every 12 hours until disease progression or unacceptable toxicity), 118 received idelalisib (150 mg approximately every 12 hours until disease progression or unacceptable toxicity) with up to 8 infusions of a rituximab product, and 35 received up to 6 cycles of bendamustine and a rituximab product. The median age overall was 68 years (range: 32-90); 67% were male; 92% were white; and 88% had an ECOG performance status of 0 or 1. In the CALQUENCE arm, serious adverse reactions occurred in 29% of patients. Serious adverse reactions in > 5% of patients who received CALQUENCE included lower respiratory tract infection (6%). Fatal adverse reactions within 30 days of the last dose of CALQUENCE occurred in 2. 6% of patients, including from second primary malignancies and infection. In recipients of CALQUENCE, permanent discontinuation due to an adverse reaction occurred in 10% of patients, most frequently due to second primary malignancies followed by infection. Adverse reactions led to dosage interruptions of CALQUENCE in 34% of patients, most often due to respiratory tract infections followed by neutropenia, and dose reduction in 3. 9% of patients. Selected adverse reactions are described in Table 10 and non-hematologic laboratory abnormalities are described in Table 11. These tables reflect exposure to CALQUENCE with median duration of 15. 7 months with 94% of patients on treatment for greater than 6 months and 86% of patients on treatment for greater than 12 months. The median duration of exposure to idelalisib was 11. 5 months with 72% of patients on treatment for greater than 6 months and 48% of patients on treatment for greater than 12 months. Eighty-three percent of patients completed 6 cycles of bendamustine and rituximab product.

Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. .

Special Population Medication

6 Risk Summary Based on findings in animals, CALQUENCE may cause fetal harm and dystocia when administered to a pregnant woman. There are no available data in pregnant women to inform the drug-associated risk. In animal reproduction studies, administration of acalabrutinib to animals during organogenesis resulted in dystocia in rats and reduced fetal growth in rabbits at maternal exposures (AUC) 2 times exposures in patients at the recommended dose of 100 mg approximately every 12 hours ( see Data. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Data Animal Data In a combined fertility and embryo-fetal development study in female rats, acalabrutinib was administered orally at doses up to 200 mg/kg/day starting 14 days prior to mating through gestational day [GD] 17. No effects on embryo-fetal development and survival were observed. The AUC at 200 mg/kg/day in pregnant rats was approximately 9 times the AUC in patients at the recommended dose of 100 mg approximately every 12 hours. The presence of acalabrutinib and its active metabolite were confirmed in fetal rat plasma. In an embryo-fetal development study in rabbits, pregnant animals were administered acalabrutinib orally at doses up to 200 mg/kg/day during the period of organogenesis (from GD 6-18). Administration of acalabrutinib at doses >= 100 mg/kg/day produced maternal toxicity and 100 mg/kg/day resulted in decreased fetal body weights and delayed skeletal ossification. The AUC at 100 mg/kg/day in pregnant rabbits was approximately 2 times the AUC in patients at 100 mg approximately every 12 hours. In a pre- and postnatal development study in rats, acalabrutinib was administered orally to pregnant animals during organogenesis, parturition and lactation, at doses of 50, 100, and 150 mg/kg/day. Dystocia (prolonged or difficult labor) and mortality of offspring were observed at doses >= 100 mg/kg/day. The AUC at 100 mg/kg/day in pregnant rats was approximately 2 times the AUC in patients at 100 mg approximately every 12 hours. Underdeveloped renal papilla was also observed in F1 generation offspring at 150 mg/kg/day with an AUC approximately 5 times the AUC in patients at 100 mg approximately every 12 hours. Risk Summary No data are available regarding the presence of acalabrutinib or its active metabolite in human milk, its effects on the breastfed child, or on milk production. Acalabrutinib and its active metabolite were present in the milk of lactating rats. Due to the potential for adverse reactions in a breastfed child from CALQUENCE, advise lactating women not to breastfeed while taking CALQUENCE and for 2 weeks after the last dose. CALQUENCE may cause embryo-fetal harm and dystocia when administered to pregnant women [see Use in Specific Populations (8. 1) Pregnancy Testing Pregnancy testing is recommended for females of reproductive potential prior to initiating CALQUENCE therapy. Contraception Females Advise female patients of reproductive potential to use effective contraception during treatment with CALQUENCE and for 1 week following the last dose of CALQUENCE. If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be informed of the potential hazard to a fetus. The safety and efficacy of CALQUENCE in pediatric patients have not been established. CLL and Previously Treated MCL Of the 1,467 CALQUENCE-treated patients with CLL or relapsed or refractory MCL in clinical trials, 977 (67%) were 65 years of age or older, and 328 (22%) were 75 years of age or older. Among patients 65 years of age or older, 74% had Grade 3 or higher adverse reactions and 58% had serious adverse reactions. Among patients younger than age 65, 61% had Grade 3 or higher adverse reactions and 39% had serious adverse reactions. No clinically relevant differences in efficacy were observed between patients >= 65 years and younger. Previously Untreated MCL Of the 297 CALQUENCE-treated patients with previously untreated MCL, 214 (72%) were 65 to 74 years of age and 83 (28%) were 75 years of age and older. No clinically relevant differences in safety or efficacy were observed between patients ages 65 to 74 years and those who were 75 years of age and older. Avoid use of CALQUENCE in patients with severe hepatic impairment (Child-Pugh class C). No dosage adjustment of CALQUENCE is recommended in patients with mild (Child-Pugh class A) or moderate (Child-Pugh class B) hepatic impairment. The safety of CALQUENCE has not been evaluated in patients with moderate or severe hepatic impairment [see Clinical Pharmacology (12.

Other Information

NONCLINICAL TOXICOLOGY
Carcinogenicity studies have not been conducted with acalabrutinib. Acalabrutinib was not mutagenic in an in vitro bacterial reverse mutation (AMES) assay or clastogenic in an in vitro human lymphocyte chromosomal aberration assay or in an in vivo rat bone marrow micronucleus assay. In a fertility study in rats, there were no effects of acalabrutinib on fertility in male rats at exposures 11 times, or in female rats at exposures 9 times, the AUC observed in patients at the recommended dose of 100 mg twice daily.
CLINICAL STUDIES
ECHO The efficacy of CALQUENCE in patients with previously untreated MCL was evaluated in a randomized, double blind, placebo controlled, multicenter study (ECHO; NCT02972840). The study enrolled 598 patients who were >= 65 years of age and who had no intention for transplant. The study excluded patients with total bilirubin > 1. 5 × upper limit of normal (ULN), AST or ALT > 2. 5 × ULN, or estimated creatinine clearance of <= 50 mL/min. Patients were randomized in a 1:1 ratio to receive CALQUENCE plus bendamustine and rituximab (CALQUENCE plus BR) or placebo plus BR. Dosing for both arms was administered in 28-day cycles as follows: 2 2 2 Patients on the control arm received the same regimen but placebo in lieu of CALQUENCE. Crossover to CALQUENCE monotherapy was permitted for patients in the placebo plus BR arm at disease progression. Of all patients randomized, the median age was 71 years (range: 65-86); 71% were male; 78% were White, 16% Asian, 0. 5% were Black or African American. In total, 80% had classic histology of MCL, 7. 7% had blastoid MCL, and 5. 5% had pleomorphic MCL. The simplified MIPI (Mantle Cell Lymphoma International Prognostic Index) score was low in 33%, intermediate in 43%, and high in 24% of patients. A total of 38% of patients had tumor bulk >= 5 cm and 86% had Ann Arbor stage IV disease. The major efficacy outcome was progression-free survival (PFS) as assessed by an Independent Review Committee (IRC) using the Lugano Classification. Efficacy results are presented in Table 12. The Kaplan-Meier curves for PFS are shown in Figure 1. At this prespecified interim analysis, the median follow-up for PFS was 49. 8 months in both arms.

Figure_1 ACE-LY-004 The efficacy of CALQUENCE was based upon Trial LY-004 titled “An Open-label, Phase 2 Study of ACP-196 in Subjects with Mantle Cell Lymphoma” (NCT02213926). Trial LY-004 enrolled a total of 124 patients with MCL who had received at least one prior therapy. The median age was 68 (range 42 to 90) years, 80% were male, and 74% were Caucasian. At baseline, 93% of patients had an ECOG performance status of 0 or 1. The median time since diagnosis was 46. 3 months and the median number of prior treatments was 2 (range 1 to 5), including 18% with prior stem cell transplant. Patients who received prior treatment with BTK inhibitors were excluded. The most common prior regimens were CHOP-based (52%) and ARA-C (34%). At baseline, 37% of patients had at least one tumor with a longest diameter >= 5 cm, 73% had extra nodal involvement including 51% with bone marrow involvement. The simplified Mantle Cell Lymphoma International Prognostic Index (MIPI) score (which includes age, ECOG score, and baseline lactate dehydrogenase and white cell count) was intermediate in 44% and high in 17% of patients. CALQUENCE was administered orally at 100 mg approximately every 12 hours until disease progression or unacceptable toxicity. The median dose intensity was 98. The major efficacy outcome of Trial LY-004 was overall response rate and the median follow-up was 15.

The median time to best response was 1. Lymphocytosis Upon initiation of CALQUENCE, a temporary increase in lymphocyte counts (defined as absolute lymphocyte count increased >= 50% from baseline and a post-baseline assessment >= 5 x 109/L) in 31. 5% of patients in Trial LY-004. The median time to onset of lymphocytosis was 1. 1 weeks, and the median duration of lymphocytosis was 6. The efficacy of CALQUENCE in patients with CLL was demonstrated in two randomized, controlled trials. The indication for CALQUENCE includes patients with SLL because it is the same disease. ELEVATE-TN The efficacy of CALQUENCE was evaluated in the ELEVATE-TN trial, a randomized, multicenter, open-label, actively controlled, 3 arm trial of CALQUENCE in combination with obinutuzumab, CALQUENCE monotherapy, and obinutuzumab in combination with chlorambucil in 535 patients with previously untreated chronic lymphocytic leukemia (NCT02475681). Patients 65 years of age or older or between 18 and 65 years of age with a total Cumulative Illness Rating Scale (CIRS) > 6 or creatinine clearance of 30 to 69 mL/min were enrolled. The trial also required hepatic transaminases <= 3 times upper limit of normal (ULN) and total bilirubin <= 1. 5 times ULN, and excluded patients with Richter’s transformation. Patients were randomized in a 1:1:1 ratio into 3 arms to receive: Randomization was stratified by 17p deletion mutation status, ECOG performance status (0 or 1 versus 2), and geographic region. A total of 535 patients were randomized, 179 to CALQUENCE+G, 179 to CALQUENCE monotherapy, and 177 to GClb. The overall median age was 70 years (range: 41 to 91 years), 47% had Rai stage III or IV disease, 14% had 17p deletion or TP53 mutation, 63% of patients had an unmutated IGVH, and 18% had 11q deletion. Baseline demographic and disease characteristics were similar between treatment arms. Efficacy was based on progression-free survival (PFS) as assessed by an Independent Review Committee (IRC). The median duration of follow-up was 28. 3 months (range: 0. Efficacy results are presented in Table 14. The Kaplan-Meier curves for PFS are shown in Figure 2.

ASCEND The efficacy of CALQUENCE in patients with relapsed or refractory CLL was based upon a multicenter, randomized, open-label trial (ASCEND; NCT02970318). The trial enrolled 310 patients with relapsed or refractory CLL after at least 1 prior systemic therapy. The trial excluded patients with transformed disease, prolymphocytic leukemia, or previous treatment with venetoclax, a Bruton tyrosine kinase inhibitor, or a phosphoinositide-3 kinase inhibitor. Patients were randomized in a 1:1 ratio to receive either: ∘ 2 2 ∘ 2 2 Randomization was stratified by 17p deletion mutation status, ECOG performance status (0 or 1 versus 2), and number of prior therapies (1 to 3 versus >= 4). Of 310 patients total, 155 were assigned to CALQUENCE monotherapy, 119 to IR, and 36 to BR. The median age overall was 67 years (range: 32 to 90 years), 42% had Rai stage III or IV disease, 28% had 17p deletion or TP53 mutation, 78% of patients had an unmutated IGVH, and 27% had a 11q deletion. The CALQUENCE arm had a median of 1 prior therapy (range: 1 to 8), with 47% having at least 2 prior therapies. The investigator’s choice arm had a median of 2 prior therapies (range: 1 to 10), with 57% having at least 2 prior therapies. In the CALQUENCE arm, the median treatment duration was 15. 7 months, with 94% of patients treated for at least 6 months and 86% of patients treated for at least 1 year. In the investigator’s choice arm, the median treatment duration was 8. 4 months, with 59% of patients treated for at least 6 months and 37% treated for at least 1 year. Efficacy was based on PFS as assessed by an IRC, with a median follow-up of 16. 1 months (range 0. Efficacy results are presented in Table 15. The Kaplan-Meier curve for PFS is shown in Figure 3.
