An ultrahigh-performance liquid chromatography-tandem mass spectrometry method for quantification of methotrexate and 7-hydroxy-methotrexate and application for therapeutic drug monitoring in patients with central nervous system lymphoma. Biomed Chromatogr 2024; 38:e5789. [PMID: 38037467 DOI: 10.1002/bmc.5789] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2023] [Revised: 11/01/2023] [Accepted: 11/06/2023] [Indexed: 12/02/2023]
Abstract
A method using ultrahigh-performance liquid chromatography-tandem mass spectrometry was developed, validated, and applied to simultaneously determine plasma methotrexate (MTX) and 7-hydroxy-methotrexate (7-OH-MTX) in 117 patients with central nervous system (CNS) lymphoma. The ion transitions utilized were m/z 455.2 > 308.2 for MTX and m/z 471.2 > 324.1 for 7-OH-MTX. Samples were prepared through protein precipitation using methanol. Chromatographic separation was achieved within 3.0 min on a CMS9030 column (Ruixi, 2.1 × 50 mm, 3 μm) through a gradient elution of methanol and a 10% ammonium acetate solution at a flow rate of 0.4 mL/min. The method demonstrated linearity in the concentration range of 0.05-10 μM for MTX and 0.25-50 μM for 7-OH-MTX. The intra- and inter-day inaccuracy ranged from -7.38% to 7.83%, and the imprecision was less than 6.00% for both analytes. The recovery and matrix effect normalized by the internal standard (MTX-D3 ) remained consistent. Both analytes remained stable under nine different storage conditions. In patients with CNS lymphoma, MTX levels at 12 h and 7-OH-MTX levels at 12, 36, and 60 h after dosing in individuals with impaired renal function were significantly higher compared with those with normal renal function. 7-OH-MTX could potentially serve as a superior indicator for nephrotoxicity compared with MTX.

Abstract
Rapidly developing UPLC-MS/MS bioassays with high throughput and quality are challenging yet desired in routine clinics. METHODS & RESULTS: A high-throughput UPLC-MS/MS bioassay has been built for simultaneously quantifying gefitinib, ruxolitinib, dasatinib, imatinib, ibrutinib, methotrexate, cyclophosphamide and paclitaxel. After the protein precipitation with methanol, samples were separated on an Acquity BEH C18 column following a gradient elution system with methanol and 2 mM ammonium acetate in water at 40 °C with a run time of 3 min (flow rate 0.4 mL/min). Mass quantification in the positive ion SRM mode was then performed with electrospray ionization. The method of specificity, linearity, accuracy, precision, matrix effects, recovery, stability, dilution integrity and carryover were all validated as per the guideline of the China Food and Drug Administration whose values met the admissible limits. Application of the bioassay to therapeutic drug monitoring revealed important variability in the studied anti-tumour drugs. CONCLUSION: This validated approach was shown to be reliable and effective in clinical management, being a valuable support in therapeutic drug monitoring and subsequent individualized dosing optimization.

Cancer Chemother Pharmacol 2023; 91:77-87. [PMID: 36463535 DOI: 10.1007/s00280-022-04498-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2022] [Accepted: 11/27/2022] [Indexed: 12/05/2022]
Abstract
PURPOSE Adenosine triphosphate (ATP)-binding cassette (ABC) transporters play an important role in the response to methotrexate (MTX). In this study, we investigated the frequency distribution of three splicing-regulatory polymorphisms in ABC transporters (ABCC2 rs2273697 G>A, ABCG2 rs2231142 G>T, and ABCB1 rs1128503 A>G) and their effects on MTX concentrations and the clinical outcome in a Chinese pediatric population with acute lymphoblastic leukemia (ALL). METHODS A fluorescence polarization immunoassay was used to measure the serum MTX concentrations in 24 h (C24h) and 42 h (C42h). The Sequenom MassARRAY system was used for single-nucleotide polymorphism (SNP) genotyping. RESULTS The study population had significantly lower frequencies of ABCC2 rs2273697 A, ABCG2 rs2231142 G, and ABCB1 rs1128503 G than African and European samples (P < 0.05). The dose-normalized MTX concentrations after 24 h and the proportion of C42h > 0.5 µmol/L were significantly lower in patients with the ABCG2 rs2231142 GG genotype than in patients with the GT or TT genotype (P = 0.01 and 0.006, respectively). No significant effects on MTX pharmacokinetics were observed for ABCC2 rs2273697 and ABCB1 rs1128503 polymorphisms. Bioinformatics analysis suggested that the three SNPs overlapped with the putative binding sites of several splicing factors. CONCLUSION In conclusion, our study confirmed the ethnicity-based differences in the distribution of the three investigated SNPs. The ABCG2 rs2231142 polymorphism exerted a significant effect on the level of MTX exposure. These findings may help explain the variability in MTX responses and optimize MTX treatment in pediatric patients with ALL.

A Validated HPLC-MS/MS Method for Quantification of Methotrexate and Application for Therapeutic Drug Monitoring in Children and Adults with Non-Hodgkin Lymphoma. Drug Des Devel Ther 2021; 15:4575-4583. [PMID: 34764639 PMCID: PMC8577619 DOI: 10.2147/dddt.s335122] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2021] [Accepted: 10/19/2021] [Indexed: 12/01/2022] Open
Abstract
Purpose A simple, rapid and reliable method to quantify methotrexate (MTX) in human plasma by high-performance liquid chromatography–tandem mass spectrometry (HPLC-MS/MS) was established and validated in two laboratories. Patients and Methods Sample separation was achieved on a Synergi Hydro-RP column (50 mm×2.0 mm, 2.5 μm) with a gradient elution program in 3.5 min after a simple protein precipitation with methanol (MeOH) and acetonitrile (ACN) (1:1). About 5 mM ammonium formate aqueous solution with 0.2% formic acid and ACN were used as mobile phase with a flow rate of 0.5 mL/min at 40 °C. Mass spectrometry detection using AB Sciex Triple Quad 4500 mass spectrometer (4500 QQQ) and Qtrap 5500 mass spectrometer (5500 Q-trap) were both characterized by electrospray ionization (ESI) for positive ions in multiple reaction-monitoring (MRM) mode. Quantitative ion pairs were m/z 455.1→m/z 308.0 for MTX and m/z 248.1→m/z 121.0 for tinidazole (TNZ) used as internal standard (IS). Results Linear calibration curves were generated over the range of 5–1000 ng/mL (r2> 0.99) on both the 4500 QQQ and 5500 Q-trap, both of the intra- and inter-batch precision were less than 7.67% and accuracy ranged from 96.33% to 108.94%. The recovery and matrix effect were 82.20–93.98% and 102.69–105.28%, respectively. Conclusion An analytical method transfer was achieved by re-verification in two laboratories to ensure stability and reproducibility and this method has been applied for therapeutic drug monitoring (TDM) successfully in children and adults with NHL, and during routine TDM, two delayed elimination of MTX cases were observed and analyzed.

Abstract
Aim: To assist therapeutic dose adjustment in clinic, a reliable concentration measurement is quite necessary for therapeutic drug monitoring. Results: A UHPLC-MS/MS bioassay for simultaneous determination of methotrexate, imatinib and dasatinib using isotope dilution internal standardization has been established and fully validated as per China Food and Drug Administration guideline. After a simple protein precipitation, the analytes were separated by a gradient elution within 3 min and mass detection was performed via ESI+ mode with SRM. The calibration curves were in the range of 5-100 ng/ml for methotrexate, 25-5000 ng/ml for imatinib and 1-250 ng/ml for dasatinib. Imprecision and inaccuracy values were ≤9.44% and ≤12.81% for all analytes, respectively. Conclusion: The developed method is appropriate for therapeutic drug monitoring, being applied to help individualized therapy in patients with acute lymphoblastic leukemia.
