CALQUENCE® (acalabrutinib) plus chemoimmunotherapy approved in the US for patients with previously untreated mantle cell lymphoma

WILMINGTON, Del.--(BUSINESS WIRE)--AstraZeneca’s CALQUENCE® (acalabrutinib) in combination with bendamustine and rituximab has been approved in the US for the treatment of adult patients with previously untreated mantle cell lymphoma (MCL) who are ineligible for autologous hematopoietic stem cell transplantation. The approval was granted by the Food and Drug Administration (FDA) after securing Priority Review. It was based on results from the ECHO Phase III trial which were presented at the European Hematology Association 2024 Congress. MCL is a rare and typically aggressive form of non-Hodgkin lymphoma (NHL), often diagnosed at an advanced stage.1,2 It is estimated that there are more than 21,000 patients diagnosed with MCL in the US, UK, France, Germany, Spain, Italy, Japan and China.3 Michael Wang, MD, Puddin Clarke Endowed Professor, Director of Mantle Cell Lymphoma Program of Excellence and principal investigator in the trial, said: “Managing this aggressive cancer requires maximizing efficacy while maintaining tolerability, especially for elderly patients. Results from the pivotal ECHO trial highlight the promise of the acalabrutinib combination in defining a new standard of care, with today’s approval underscoring the transformative potential of this regimen as a first-line treatment for older patients with mantle cell lymphoma.” Dave Fredrickson, Executive Vice President, Oncology Business Unit, AstraZeneca, said: “With today’s approval, CALQUENCE provides a critical new treatment option to mantle cell lymphoma patients in the US, with CALQUENCE proven to deliver nearly one and a half years of additional time without disease progression. This approval brings a new and effective treatment option to those living with this disease and further reinforces our belief in CALQUENCE as a backbone therapy across multiple blood cancers.” Meghan Gutierrez, Chief Executive Officer, Lymphoma Research Foundation, said: “New treatment options have long been needed in the first-line treatment of mantle cell lymphoma in the US. Patients with this rare and often aggressive cancer can experience severe symptoms by the time they are diagnosed - having an effective therapy that can significantly improve outcomes for patients early in the treatment process is a much-needed advancement.” Results from the ECHO trial showed CALQUENCE plus bendamustine and rituximab reduced the risk of disease progression or death by 27% compared to standard-of-care chemoimmunotherapy (hazard ratio [HR] 0.73; 95% confidence interval [CI] 0.57-0.94; p=0.016). Median PFS was 66.4 months for patients treated with the CALQUENCE combination versus 49.6 months with chemoimmunotherapy alone. This approval additionally converts CALQUENCE’s accelerated approval to a full approval for adult patients with MCL treated with at least one prior therapy, as granted by the FDA in October 2017. The ECHO trial enrolled patients throughout the COVID-19 pandemic. After censoring for COVID-19 deaths, PFS was further improved in both arms, with the CALQUENCE combination reducing the risk of disease progression or death by 36% (HR 0.64; 95% CI 0.48-0.84). Although OS data were not mature at the time of the analysis, when censored for COVID-19, a favorable trend was seen for OS (HR 0.75; 95% CI 0.53-1.04), despite 69% of patients in the chemoimmunotherapy arm receiving treatment with a BTK inhibitor on relapse or disease progression. The safety and tolerability of CALQUENCE was consistent with its known safety profile, and no new safety signals were identified. The US regulatory submission was reviewed under Project Orbis, which provides a framework for concurrent submission and review of oncology medicines among participating international partners. As part of Project Orbis, CALQUENCE plus chemoimmunotherapy is also under review by regulatory authorities in Australia, Canada, and Switzerland for the same indication. Regulatory applications are also under review in the EU, Japan, and other countries based on the ECHO results. INDICATIONS AND USAGE CALQUENCE is a Bruton tyrosine kinase (BTK) inhibitor indicated in combination with bendamustine and rituximab (BR) for the treatment of adult patients with previously untreated mantle cell lymphoma (MCL) who are ineligible for autologous hematopoietic stem cell transplantation (HSCT), as monotherapy for the treatment of adult patients with MCL who have received at least one prior therapy, and for the treatment of adult patients with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL). IMPORTANT SAFETY INFORMATION ABOUT CALQUENCE® (acalabrutinib) tablets Serious and Opportunistic Infections Fatal and serious infections, including opportunistic infections, have occurred in patients with hematologic malignancies treated with CALQUENCE. Serious or Grade 3 or higher infections (bacterial, viral, or fungal) occurred in 32% of 1,764 patients exposed to CALQUENCE in clinical trials, most often due to respiratory tract infections (19% of all patients, including pneumonia in 9%). These infections predominantly occurred in the absence of Grade 3 or 4 neutropenia, with neutropenic infection reported in 2.7% of all patients. Opportunistic infections in recipients of CALQUENCE have included, but are not limited to, hepatitis B virus reactivation, fungal pneumonia, Pneumocystis jirovecii pneumonia, Epstein-Barr virus reactivation, cytomegalovirus, and progressive multifocal leukoencephalopathy (PML). Consider prophylaxis in patients who are at increased risk for opportunistic infections. Monitor patients for signs and symptoms of infection and treat promptly. Hemorrhage Fatal and serious hemorrhagic events have occurred in patients treated with CALQUENCE. Major hemorrhage (serious or Grade 3 or higher bleeding or any central nervous system bleeding) occurred in 4.4% of patients, with fatal hemorrhage occurring in 0.2% of 1,764 patients exposed to CALQUENCE in clinical trials. Bleeding events of any grade, excluding bruising and petechiae, occurred in 40% of patients. Use of antithrombotic agents concomitantly with CALQUENCE may further increase the risk of hemorrhage. In clinical trials, major hemorrhage occurred in 7% of patients taking CALQUENCE without antithrombotic agents and 4% of patients taking CALQUENCE with antithrombotic agents. Consider the risks and benefits of antithrombotic agents when co-administered with CALQUENCE. Monitor patients 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. Cytopenias CALQUENCE can cause Grade 3 or 4 cytopenias. Grade 3 or 4 cytopenias included absolute neutrophil count decreased (26%), platelets decreased (10%), hemoglobin decreased (10%), and absolute lymphocyte count decreased (10%) in patients treated with CALQUENCE alone or in combination with obinutuzumab; Grade 4 neutropenia developed in 14% of patients. Monitor complete blood counts regularly during treatment. Interrupt treatment, reduce the dose, or discontinue treatment as warranted. Second Primary Malignancies Second primary malignancies, including skin cancers and other solid tumors, occurred in 18% of 1,764 patients exposed to CALQUENCE in clinical trials. The most frequent second primary malignancy was non-melanoma skin cancer, reported in 10% of patients, followed by other solid tumors in 9% (including melanoma, lung cancer, gastrointestinal cancers, and genitourinary cancers) and hematologic malignancies (1%). Monitor patients for the development of second cancers and advise protection from sun exposure. Cardiac Arrhythmias Fatal and serious cardiac arrhythmias have occurred in patients treated with CALQUENCE. Grade 3 or 4 atrial fibrillation or flutter was reported in 2.6% of 1,764 patients treated with CALQUENCE, with all grades of atrial fibrillation or flutter reported in 7% of all patients. Grade 3 or higher ventricular arrhythmia events were reported in 0.6% of patients, including fatal cases in 0.3% of all patients. The risk of arrhythmias may be increased in patients with cardiac risk factors, hypertension, previous arrhythmias, and acute infection. Monitor for symptoms of arrhythmia (eg, palpitations, dizziness, syncope, dyspnea) and manage as appropriate. Hepatotoxicity, Including Drug-Induced Liver Injury Hepatotoxicity, including severe, life-threatening, and potentially fatal cases of drug-induced liver injury (DILI), has occurred in patients treated with Bruton tyrosine kinase inhibitors, including CALQUENCE. Evaluate bilirubin and transaminases at baseline and throughout treatment with CALQUENCE. For patients who develop abnormal liver tests after CALQUENCE, monitor more frequently for liver test abnormalities and clinical signs and symptoms of hepatic toxicity. If DILI is suspected, withhold CALQUENCE. Upon confirmation of DILI, discontinue CALQUENCE.

Adverse reactions led to permanent discontinuation of CALQUENCE in 43%, dosage interruptions in 74%, and dosage reductions in 10% of patients. Adverse reactions that resulted in dosage modification in >10% included infections, cytopenias, rashes, and gastrointestinal toxicity. Adverse reactions which resulted in permanent discontinuation of CALQUENCE in ≥4% of patients included COVID-19 (includes COVID-19 pneumonia) and neutropenia. Previously Treated Mantle Cell Lymphoma The most common adverse reactions (≥20%) of any grade in patients with relapsed or refractory MCL exposed to CALQUENCE were anemia,* thrombocytopenia,* headache (39%), neutropenia,* diarrhea (31%), fatigue (28%), myalgia (21%), and bruising (21%). The most common Grade ≥3 non-hematological adverse reaction (reported in at least 2% of patients) was diarrhea (3.2%). *Treatment-emergent decreases (all grades) of hemoglobin (46%), platelets (44%), and neutrophils (36%) were based on laboratory measurements and adverse reactions. Dose reductions or discontinuations due to any adverse reaction were reported in 1.6% and 6.5% of patients, respectively. Increases in creatinine to 1.5 to 3 times the upper limit of normal (ULN) occurred in 4.8% of patients. Chronic Lymphocytic Leukemia The most common adverse reactions (≥30%) of any grade in patients with CLL exposed to CALQUENCE were anemia,* neutropenia,* thrombocytopenia,* headache, upper respiratory tract infection, and diarrhea. *Treatment-emergent decreases (all grades) of hemoglobin, platelets, and neutrophils were based on laboratory measurements and adverse reactions. In patients with previously untreated CLL exposed to CALQUENCE, 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 plus obinutuzumab arm and 32% in the CALQUENCE monotherapy arm, most often due to events of pneumonia (2.8% to 7%). Adverse reactions led to CALQUENCE dose reduction in 7% and 4% of patients in the CALQUENCE plus obinutuzumab arm (N=178) and CALQUENCE monotherapy arm (N=179), respectively. Adverse events led to discontinuation in 11% and 10% of patients, respectively. Increases in creatinine to 1.5 to 3 times ULN occurred in 3.9% and 2.8% of patients in the CALQUENCE combination arm and monotherapy arm, respectively. In patients with relapsed/refractory CLL exposed to CALQUENCE, 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. Adverse reactions led to CALQUENCE dose reduction in 3.9% of patients (N=154), dose interruptions in 34% of patients, most often due to respiratory tract infections followed by neutropenia, and discontinuation in 10% of patients, most frequently due to second primary malignancies followed by infection. Increases in creatinine to 1.5 to 3 times ULN occurred in 1.3% of patients who received CALQUENCE. DRUG INTERACTIONS Strong CYP3A Inhibitors: Avoid co-administration of CALQUENCE with a strong CYP3A inhibitor. If these inhibitors will be used short-term, interrupt CALQUENCE. After discontinuation of strong CYP3A inhibitor for at least 24 hours, resume previous dosage of CALQUENCE. Moderate CYP3A Inhibitors: Reduce the dosage of CALQUENCE to 100 mg once daily when co-administered with a moderate CYP3A inhibitor. Strong CYP3A Inducers: Avoid co-administration of CALQUENCE with a strong CYP3A inducer. If co-administration is unavoidable, increase the dosage of CALQUENCE to 200 mg approximately every 12 hours. SPECIFIC POPULATIONS 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. Advise pregnant women of the potential risk to a fetus. Pregnancy testing is recommended for females of reproductive potential prior to initiating CALQUENCE therapy. Advise female patients of reproductive potential to use effective contraception during treatment with CALQUENCE and for 1 week following the last dose of CALQUENCE. It is not known if CALQUENCE is present in human milk. Advise lactating women not to breastfeed while taking CALQUENCE and for 2 weeks after the last dose. 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. Please see full Prescribing Information, including Patient Information. Notes Mantle cell lymphoma While MCL patients initially respond to treatment, patients do tend to relapse.4 MCL comprises about 3-6% of non-Hodgkin lymphomas, with an annual incidence of 0.5 per 100,000 population in Western countries; in the US, it is estimated that approximately 4,000 new patients are diagnosed with MCL each year.4,5 ECHO ECHO is a randomized, double-blind, placebo-controlled, multi-center Phase III trial evaluating the efficacy and safety of CALQUENCE plus bendamustine and rituximab compared to SoC chemoimmunotherapy (bendamustine and rituximab) in adult patients at or over 65 years of age (n=635) with previously untreated MCL.6 Patients were randomized 1:1 to receive either CALQUENCE or placebo administered orally twice per day, continuously, until disease progression or unacceptable toxicity. Additionally, all patients received six 28-day cycles of bendamustine on days 1 and 2 and rituximab on day 1 of each cycle, followed by rituximab maintenance for two years if patients achieved a response after induction therapy.6 The primary endpoint is PFS assessed by an Independent Review Committee; other efficacy endpoints include OS, overall response rate (ORR), duration of response (DoR) and time to response (TTR).6 The trial was conducted in 27 countries across North and South America, Europe, Asia and Oceania.6 The ECHO trial enrolled patients from May 2017 to March 2023, continuing through the COVID-19 pandemic. Prespecified PFS and OS analyzes censoring for COVID-19 deaths were conducted to assess the impact of COVID-19 on the study outcome in alignment with the FDA. Patients with blood cancer remain at a disproportionately high risk of severe outcomes from COVID-19, including hospitalization and death compared to the general population.6,7 CALQUENCE CALQUENCE (acalabrutinib) is a second-generation, selective inhibitor of Bruton’s tyrosine kinase (BTK). CALQUENCE binds covalently to BTK, thereby inhibiting its activity.8 In B-cells, BTK signaling results in activation of pathways necessary for B-cell proliferation, trafficking, chemotaxis and adhesion. CALQUENCE has been used to treat more than 85,000 patients worldwide9 and is approved for the treatment of chronic lymphocytic leukemia (CLL) and small lymphocytic lymphoma (SLL) in the US and Japan, approved for CLL in the EU and many other countries worldwide and approved in China for relapsed or refractory CLL and SLL. CALQUENCE is also approved for the treatment of adult patients with previously untreated MCL in the US, and in China and several other countries for the treatment of adult patients with mantle cell lymphoma (MCL) who have received at least one prior therapy. CALQUENCE is not currently approved for the treatment of MCL in Japan or the EU. As part of an extensive clinical development program, CALQUENCE is currently being evaluated as a single treatment and in combination with standard-of-care chemoimmunotherapy for patients with multiple B-cell blood cancers, including CLL, MCL and diffuse large B-cell lymphoma.
