Abstract
Lenvatinib (LEN) is a multitargeted tyrosine kinase inhibitor registered for the first-line treatment of unresectable advanced hepatocellular carcinoma. Wuzhi capsule (WZC) is a traditional Chinese medicine preparation; it is used to decrease the aminotransferase level of the liver and protect liver function. Thus, patients with hepatocellular carcinoma (HCC) are potentially treated with a combination of LEN and WZC, but there is no information about the interaction between the two drugs. We developed a simple, rapid, and sensitive ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) method for the quantitative determination of lenvatinib in rat plasma. Liquid-liquid extraction of plasma samples was carried out with ethyl acetate. Chromatographic separation of analyte was performed using gradient elution with acetonitrile and 0.1% formic acid water. The positive ion multi-response monitoring mode was used, and the target of the parent and daughter ions of LEN and IS were m/z 427.1→370 and m/z 432.1→370, respectively. All the validation projects were in accordance with the guidelines. Good linearity of 0.2-1000 ng/mL (r > 0.999) was achieved. The lower limit of quantification was 0.2 ng/mL. The precision and accuracy are acceptable. The method was successfully applied to pharmacokinetics and drug interaction analysis. The results show that WZC can significantly increase the Cmax (maximum plasma concentration) and AUC (area under the concentration-time curve) of LEN. An UPLC -MS/MS method that can be used for studying drug-drug interaction as a valuable tool was developed in this study. Drug-drug interactions were observed between the WZC and LEN.

Quantification of sorafenib, lenvatinib, and apatinib in human plasma for therapeutic drug monitoring by UPLC-MS/MS. J Pharm Biomed Anal 2021; 202:114161. [PMID: 34052550 DOI: 10.1016/j.jpba.2021.114161] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2020] [Revised: 05/08/2021] [Accepted: 05/19/2021] [Indexed: 12/24/2022]
Abstract
Sorafenib, lenvatinib, and apatinib, as multi-targeted tyrosine kinase inhibitors with anti-proliferative and anti-angiogenic effects, are widely used for systemic therapy in advanced hepatocellular carcinoma patients. Nevertheless, insufficient efficacy or adverse effects often appear due to the significant inter-individual variability of plasma concentration for these drugs. In order to carry out therapeutic drug monitoring of these drugs and then ensure the effectiveness and safety of the medical treatment, the first method allowing to quantify sorafenib, lenvatinib, and apatinib simultaneously in human plasma was developed in this study. The analysis was performed by UPLC-MS/MS system and the chromatographic separation was achieved on a C18 column using a gradient elution of water-acetonitrile in 3.5 min. This method presented satisfactory results in terms of specificity, precision (coefficient of variation of intra-day and inter-day:1.4-6.6 %), accuracy (92.6-105.4 %), matrix effects (96.9-107.2 %), extraction recovery (90.5-99.4 %), as well as stability in human plasma and even whole blood under certain conditions. This sensitive, rapid and simple method was successfully applied to the analysis of sorafenib, lenvatinib and apatinib for therapeutic drug monitoring in hepatocellular carcinoma patients, and it was expected to be applied to further study about clarifying the concentration- efficacy and concentration-toxic relationship of sorafenib, lenvatinib, and apatinib in hepatocellular carcinoma patients.

Questions and Controversies in the Clinical Application of Tyrosine Kinase Inhibitors to Treat Patients with Radioiodine-Refractory Differentiated Thyroid Carcinoma: Expert Perspectives.

Abstract
Notwithstanding regulatory approval of lenvatinib and sorafenib to treat radioiodine-refractory differentiated thyroid carcinoma (RAI-R DTC), important questions and controversies persist regarding this use of these tyrosine kinase inhibitors (TKIs). RAI-R DTC experts from German tertiary referral centers convened to identify and explore such issues; this paper summarizes their discussions. One challenge is determining when to start TKI therapy. Decision-making should be shared between patients and multidisciplinary caregivers, and should consider tumor size/burden, growth rate, and site(s), the key drivers of RAI-R DTC morbidity and mortality, along with current and projected tumor-related symptomatology, co-morbidities, and performance status. Another question involves choice of first-line TKIs. Currently, lenvatinib is generally preferred, due to greater increase in progression-free survival versus placebo treatment and higher response rate in its pivotal trial versus that of sorafenib; additionally, in those studies, lenvatinib but not sorafenib showed overall survival benefit in subgroup analysis. Whether recommended maximum or lower TKI starting doses better balance anti-tumor effects versus tolerability is also unresolved. Exploratory analyses of lenvatinib pivotal study data suggest dose-response effects, possibly favoring higher dosing; however, results are awaited of a prospective comparison of lenvatinib starting regimens. Some controversy surrounds determination of net therapeutic benefit, the key criterion for continuing TKI therapy: if tolerability is acceptable, overall disease control may justify further treatment despite limited but manageable progression. Future research should assess potential guideposts for starting TKIs; fine-tune dosing strategies and further characterize antitumor efficacy; and evaluate interventions to prevent and/or treat TKI toxicity, particularly palmar-plantar erythrodysesthesia and fatigue.
