Acalabrutinib, sold under the brand name Calquence, is a medication used to treat various types of non-Hodgkin lymphoma, including mantle cell lymphoma (MCL) and chronic lymphocytic leukemia/small lymphocytic Lymphoma (CLL/SLL). [6] It may be used both in relapsed as well as in treatment-naive settings. [7]

Contents

Common side effects include headaches, feeling tired, low red blood cells, low platelets, and low white blood cells. [6] It is a second generation Bruton's tyrosine kinase inhibitor. [8] [9] Acalabrutinib blocks an enzyme called Bruton's tyrosine kinase, which helps B cells to survive and grow. [4] By blocking this enzyme, acalabrutinib is expected to slow down the build-up of cancerous B cells in CLL, thereby delaying progression of the cancer. [4]

Acalabrutinib was approved for medical use in the United States in 2017, [6] and in the European Union in November 2020. [4]

Medical uses

In the European Union, acalabrutinib as monotherapy or in combination with obinutuzumab is indicated for the treatment of adults with previously untreated chronic lymphocytic leukaemia (CLL). [4] It is also indicated for the treatment of adults with chronic lymphocytic leukaemia (CLL) who have received at least one prior therapy. [4]

In the United States, acalabrutinib is indicated for the treatment of adults with mantle cell lymphoma (MCL) who have received at least one prior therapy, and for the treatment of adults with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL). [3]

Side effects

The most common adverse events were headache, diarrhea and weight gain. [9] Despite the appearance of a greater occurrence of transient headaches, data suggest a preferred advantage of acalabrutinib over ibrutinib due to expected reduced adverse events of skin rash, severe diarrhea, and bleeding risk. [9]

Society and culture

Acalabrutinib was approved for medical use in the United States in 2017, [6] and in the European Union in November 2020. [4]

As of February 2016, acalabrutinib had received orphan drug designation in the United States for mantle cell lymphoma and chronic lymphocytic leukemia (CLL), [10] [11] and was similarly designated as an orphan medicinal product by the European Medicines Agency (EMA) Committee for Orphan Medicinal Products (COMP) for treatment of three indications: CLL/small lymphocytic lymphoma (SLL), mantle cell lymphoma (MCL), and lymphoplasmacytic lymphoma (Waldenström's macroglobulinaemia, WM). [12] [13] [14] [15] Approval would result in a 10-year period of market exclusivity for the stated indications within Europe. [16]

Economics

It was developed by Acerta Pharma. [17] After promising results for CLL in initial clinical trials, [8] Astra Zeneca purchased a 55% stake in Acerta Pharma for $4 billion in December 2015, with an option to acquire the remaining 45% stake for an additional $3 billion, conditional on approval in both the US and Europe and the establishment of commercial opportunity. [18]

Names

Acalabrutinib is the international nonproprietary name (INN), [19] and the United States Adopted Name (USAN). [20]

Research

Relative to ibrutinib, acalabrutinib demonstrated higher selectivity and inhibition of the targeted activity of BTK, while having a much greater IC50 or otherwise virtually no inhibition on the kinase activities of ITK, EGFR, ERBB2, ERBB4, JAK3, BLK, FGR, FYN, HCK, LCK, LYN, SRC, and YES1. [9] In addition, in platelets treated with ibrutinib, thrombus formation was clearly inhibited while no impact to thrombus formation was identified relative to controls for those treated with acalabrutinib. [9] These findings strongly suggest an improved safety profile of acalabrutinib with minimized adverse effects relative to ibrutinib. [9] In pre-clinical studies, it was shown to be more potent and selective than ibrutinib, the first-in-class BTK inhibitor. [8] [9]

The interim results of the still on-going[ when? ] first human phase I/II clinical trial (NCT02029443) with 61 patients for the treatment of relapsed chronic lymphocytic leukemia (CLL) are encouraging, with a 95% overall response rate demonstrating potential to become a best-in-class treatment for CLL. [8] Notably, a 100% response rate was achieved for those people which were positive for the 17p13.1 gene deletion, a subgroup that typically results in a poor response to therapy and expected outcomes. [9]

<span class="mw-page-title-main">Chronic lymphocytic leukemia</span> Medical condition

Chronic lymphocytic leukemia (CLL) is a type of cancer in which the bone marrow makes too many lymphocytes. Early on, there are typically no symptoms. Later, non-painful lymph node swelling, feeling tired, fever, night sweats, or weight loss for no clear reason may occur. Enlargement of the spleen and low red blood cells (anemia) may also occur. It typically worsens gradually over years.

Under the brand name Arzerra, it is approved for the treatment of certain types of chronic lymphocytic leukemia (CLL) in the United States. It is sold by Novartis under license from Genmab.

Richter's transformation (RT), also known as Richter's syndrome, is the conversion of chronic lymphocytic leukemia (CLL) or its variant, small lymphocytic lymphoma (SLL), into a new and more aggressively malignant disease. CLL is the circulation of malignant B lymphocytes with or without the infiltration of these cells into lymphatic or other tissues while SLL is the infiltration of these malignant B lymphocytes into lymphatic and/or other tissues with little or no circulation of these cells in the blood. CLL along with its SLL variant are grouped together in the term CLL/SLL.

<span class="mw-page-title-main">Ibrutinib</span> Medication used in cancer treatment

Ibrutinib, sold under the brand name Imbruvica among others, is a small molecule drug that inhibits B-cell proliferation and survival by irreversibly binding the protein Bruton's tyrosine kinase (BTK). Blocking BTK inhibits the B-cell receptor pathway, which is often aberrantly active in B cell cancers. Ibrutinib is therefore used to treat such cancers, including mantle cell lymphoma, chronic lymphocytic leukemia, and Waldenström's macroglobulinemia. Ibrutinib also binds to C-terminal Src Kinases. These are off-target receptors for the BTK inhibitor. Ibrutinib binds to these receptors and inhibits the kinase from promoting cell differentiation and growth. This leads to many different side effects like left atrial enlargement and atrial fibrillation during the treatment of Chronic Lymphocytic Leukemia.
