Targeting BTK in CLL: Beyond Ibrutinib
Curr Hematol Malig Rep 2019 Jun;14(3):197-205.PMID:31028669DOI:10.1007/s11899-019-00512-0.
Purpose of review: While the Bruton's tyrosine kinase inhibitor (BTKi) ibrutinib has revolutionized the treatment of chronic lymphocytic leukemia (CLL), current limitations include off-target toxicities and the development of resistance. In this review, we summarize the emerging data for alternative BTKi. Recent findings: Second-generation BTKi include acalabrutinib, zanubrutinib, and Tirabrutinib which offer greater BTK selectivity. While these agents may limit off-target toxicity, they do not overcome common mechanisms of ibrutinib resistance. Reversible BTKi including vecabrutinib and LOXO-305 inhibit BTK in the presence of C481S mutation, and non-selective reversible BTKi, including ARQ-531, may retain activity despite mutations within PLCG2. Early-phase studies are underway to establish the clinical efficacy and toxicity of these agents. A randomized trial of ibrutinib versus acalabrutinib is ongoing, and acalabrutinib may be an option for ibrutinib-intolerant patients. Results from ongoing trials of alternate BTKi will help to define their role in CLL therapy as single agents or in combination therapy.
Comparative Analysis of BTK Inhibitors and Mechanisms Underlying Adverse Effects
Front Cell Dev Biol 2021 Mar 11;9:630942.PMID:33777941DOI:10.3389/fcell.2021.630942.
The cytoplasmic protein-tyrosine kinase BTK plays an essential role for differentiation and survival of B-lineage cells and, hence, represents a suitable drug target. The number of BTK inhibitors (BTKis) in the clinic has increased considerably and currently amounts to at least 22. First-in-class was ibrutinib, an irreversible binder forming a covalent bond to a cysteine in the catalytic region of the kinase, for which we have identified 228 active trials listed at ClinicalTrials.gov. Next-generation inhibitors, acalabrutinib and zanubrutinib, are approved both in the United States and in Europe, and zanubrutinib also in China, while Tirabrutinib is currently only registered in Japan. In most cases, these compounds have been used for the treatment of B-lymphocyte tumors. However, an increasing number of trials instead addresses autoimmunity and inflammation in multiple sclerosis, rheumatoid arthritis, pemphigus and systemic lupus erythematosus with the use of either irreversibly binding inhibitors, e.g., evobrutinib and tolebrutinib, or reversibly binding inhibitors, like fenebrutinib. Adverse effects (AEs) have predominantly implicated inhibition of other kinases with a BTKi-binding cysteine in their catalytic domain. Analysis of the reported AEs suggests that ibrutinib-associated atrial fibrillation is caused by binding to ERBB2/HER2 and ERBB4/HER4. However, the binding pattern of BTKis to various additional kinases does not correlate with the common assumption that skin manifestations and diarrhoeas are off-target effects related to EGF receptor inhibition. Moreover, dermatological toxicities, diarrhoea, bleedings and invasive fungal infections often develop early after BTKi treatment initiation and subsequently subside. Conversely, cardiovascular AEs, like hypertension and various forms of heart disease, often persist.
Management of Waldenström macroglobulinemia in 2020
Hematology Am Soc Hematol Educ Program 2020 Dec 4;2020(1):372-379.PMID:33275726DOI:10.1182/hematology.2020000121.
The management of Waldenström macroglobulinemia (WM) has evolved tremendously with recent genomic discoveries that correlate with clinical presentation and could help to tailor treatment approaches. The current diagnosis of WM requires clinicopathological criteria, including bone marrow involvement by lymphoplasmacytic lymphoma cells, a serum immunoglobulin M (IgM) monoclonal paraprotein, and presence of the MYD88 L265P mutation. Once the diagnosis is established, the relationship between the patient's symptoms and WM should be carefully investigated, because therapy should be reserved for symptomatic patients. Bone marrow involvement and serum levels of IgM, albumin, and β2-microglobulin can be used to estimate the time until treatment initiation. The treatment of WM patients should be highly personalized, and the patient's clinical presentation, comorbidities, genomic profile, and preferences, as well as toxicity of the treatment regimens, should be taken into account. Alkylating agents (bendamustine, cyclophosphamide), proteasome inhibitors (bortezomib, carfilzomib, ixazomib), anti-CD20 monoclonal antibodies (rituximab, ofatumumab), and Bruton tyrosine kinase (BTK) inhibitors (ibrutinib, acalabrutinib, zanubrutinib) are safe and highly effective treatment options in patients with WM. Because novel covalent and noncovalent BTK inhibitors (Tirabrutinib, vecabrutinib, LOXO-305, ARQ-531), BCL2 antagonists (venetoclax), and CXCR4-targeting agents (ulocuplumab, mavorixafor) are undergoing clinical development in WM, the future of WM therapy certainly appears bright and hopeful.
Phase I study of Tirabrutinib (ONO-4059/GS-4059) in patients with relapsed or refractory B-cell malignancies in Japan
Cancer Sci 2019 May;110(5):1686-1694.PMID:30815927DOI:10.1111/cas.13983.
We evaluated the safety, efficacy, pharmacokinetics, pharmacodynamics and predictive biomarkers of Tirabrutinib, a second-generation, enhanced-selectivity Bruton's tyrosine kinase inhibitor in Japanese patients with relapsed/refractory B-cell non-Hodgkin lymphoma (B-cell NHL) and chronic lymphocytic leukemia (CLL). This was an open-label, multicenter, phase I study. Seventeen patients (male N = 8) with a median age of 70 years were enrolled in 4 dose cohorts (160 mg once daily [N = 3], 320 mg once daily [N = 3], 480 mg once daily [N = 4] and 300 mg twice daily [N = 7]); 4 patients had continued Tirabrutinib administration as of 4 January 2018. The maximum tolerated dose was not reached. Pneumonitis (N = 1) was the dose-limiting toxicity for 300 mg twice daily. Common adverse events (AEs) were rash (35.3%) and vomiting (29.4%). Eight patients (47.1%) developed grade ≥3 AEs: neutropenia (23.5%), anemia (11.8%) and leukopenia (11.8%) were frequent. The overall response rate (≥PR) was 76.5% (13/17 patients), including 4 DLBCL patients with no CD79A/B or MYD88 mutations, and 1 CLL patient with a TP53 mutation, providing promising data for future developments. Of 16 patients with measurable lesions during the screening period, 12 showed ≥50% reductions in tumor diameter. In many patients, the tumor size decreased soon after beginning treatment. The maximum serum concentration for Tirabrutinib was 611, 1220, 1280 and 886 ng/mL on Day 1 and 484, 971 1940, and 961 ng/mL on Day 28 for Cohorts 1-4, respectively. Tirabrutinib pharmacokinetics were linear, with little accumulation following multiple doses. Tirabrutinib was well tolerated and showed promising efficacy for B-cell NHL/CLL.
Consensus treatment recommendations from the tenth International Workshop for Waldenström Macroglobulinaemia
Lancet Haematol 2020 Nov;7(11):e827-e837.PMID:33091356DOI:10.1016/S2352-3026(20)30224-6.
Waldenström macroglobulinaemia is an indolent B-cell lymphoma with clearly defined criteria for diagnosis, initiation of therapy, and response, which was established by consensus panels at previous International Workshops for Waldenström Macroglobulinaemia (IWWM). The treatment options for Waldenström macroglobulinaemia continued to be researched after the publication of the eighth IWWM consensus recommendations in 2016, and at the tenth IWWM in New York, USA (October, 2018) an international consensus panel was formed to update treatment recommendations. Participants were selected as members of the consensus panel based on their expertise on Waldenström macroglobulinaemia. The initial live discussion took place during the tenth IWWM meeting and two separate teleconferences were held in June, 2019, and January, 2020, to refine recommendations. No external or financial support was received for the elaboration of these recommendations. According to these updated consensus recommendations, alkylating drugs (bendamustine, cyclophosphamide) and proteasome inhibitors (bortezomib, carfilzomib, ixazomib), both in combination with rituximab, as well as BTK inhibitors (ibrutinib), alone or in combination with rituximab, are preferred first-line therapy options for symptomatic patients with Waldenström macroglobulinaemia. In previously treated patients with Waldenström macroglobulinaemia who had an initial durable response, reuse of a previous regimen or another primary therapy regimen are acceptable options. Novel BTK inhibitors (acalabrutinib, zanubrutinib, Tirabrutinib) and the BCL2 antagonist venetoclax appear safe and active, and represent emerging options for the treatment of Waldenström macroglobulinaemia. The choice of therapy should be guided by the patient's clinical profile, genomic features, and drug availability.
