[PMID: 38584556 DOI: 10.2174/0118715206290110240326071909] [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: 01/03/2024] [Revised: 02/29/2024] [Accepted: 03/11/2024] [Indexed: 04/09/2024]
Abstract
BACKGROUND Ultra-performance Liquid Chromatography-tandem Mass Spectrometry (UPLC-MS/MS) is widely used for concentration detection of many Tyrosine Kinase Inhibitors (TKIs), including afatinib, crizotinib, and osimertinib. In order to analyze whether pralsetinib takes effect in Rearranged during Transfection (RET)-positive patients with central nervous system metastasis, we aimed to develop a method for the detection of pralsetinib concentrations in human plasma and Cerebrospinal Fluid (CSF) by UPLC-MS/MS. METHODS The method was developed using the external standard method, and method validation included precision, accuracy, stability, extraction recovery, and matrix effect. Working solutions were all obtained based on stock solutions of pralsetinib of 1mg/mL. The plasma/CSF samples were precipitated by acetonitrile for protein precipitation and then separated on an ACQUITY UPLC HSS T3 column (2.1×100 mm, 1.8 μm) with a gradient elution using 0.1% formic acid (solution A) and acetonitrile (solution B) as mobile phases at a flow rate of 0.4 mL/min. The tandem mass spectrometry was performed by a triple quadrupole linear ion trap mass spectrometry system (QTRAPTM 6500+) with an electrospray ion (ESI) source and Analyst 1.7.2 data acquisition system. Data were collected in Multiple Reaction Monitoring (MRM) and positive ionization mode. RESULTS A good linear relationship of pralsetinib in both plasma and CSF was successfully established, and the calibration ranges were found to be 1.0-64.0 μg/mL and 50.0ng/mL-12.8 μg/mL for pralsetinib in the plasma and CSF, respectively. Validation was performed, including calibration assessment, selectivity, precision, accuracy, matrix effect, extraction recovery, and stability, and all results have been found to be acceptable. The method has been successfully applied to pralsetinib concentration detection in a clinical sample, and the concentrations have been found to be 475 ng/mL and 61.55 μg/mL in the CSF and plasma, respectively. CONCLUSION We have developed a quick and effective method for concentration detection in both plasma and CSF, and it can be applied for drug monitoring in clinical practice. The method can also provide a reference for further optimization.

Abstract
Neurotrophic tropomyosin receptor kinase (NTRK) gene fusion has been identified as an oncogenic driver of various solid tumors, and it is rare in non-smalll cell lung cancer (NSCLC) with a frequency of approximately less than 1%. Next-generation sequencing (NGS) is of priority for detecting NTRK fusions, especially RNA-based NGS. Currently, the tropomyosin receptor kinase (TRK) inhibitors have shown promising efficacy and well tolerance in patients with NTRK fusion-positive solid tumors, regardless of tumor histology. The first-generation TRK inhibitors (larotrectinib and entrectinib) are recommended as the first-line treatment for locally advanced or metastatic NSCLC patients with positive NTRK fusion. However, TRK inhibitor resistance can eventually occur due to on-target or off-target mechanisms. Further studies are under investigation to overcome resistance and improve survival. Interestingly, NTRK fusion might be the mechanism of resistance to epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitors (TKI) in NSCLC patients with EGFR mutation. Regarding immunotherapy, the efficacy of immune checkpoint inhibitors in NSCLC patients harboring NTRK fusion has yet to be well described. In this review, we elucidate the function of NTRK genes, summarize the diagnostic techniques for NTRK fusions, and present clinical data for TRK inhibitors; we also discuss potential mechanisms of resistance to TRK inhibitors.

ABCB1 and ABCG2 Restrict Brain and Testis Accumulation and, Alongside CYP3A, Limit Oral Availability of the Novel TRK Inhibitor Selitrectinib. Mol Cancer Ther 2021; 20:1173-1182. [PMID: 33785654 DOI: 10.1158/1535-7163.mct-20-0705] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2020] [Revised: 11/07/2020] [Accepted: 03/12/2021] [Indexed: 11/16/2022]
Abstract
Selitrectinib (BAY2731954; LOXO-195) is a promising oral tropomyosin receptor kinase (TRK) inhibitor currently in phase I/II clinical trials for the treatment of histology-agnostic cancers positive for TRK fusions. With therapeutic resistance eventually developing with first-generation TRK inhibitors, selitrectinib was designed to overcome resistance mediated by acquired kinase domain mutations. Using genetically modified mouse models and pharmacological inhibitors, we investigated the roles of the multidrug efflux transporters ABCB1 and ABCG2, and the drug-metabolizing CYP3A enzyme complex in selitrectinib pharmacokinetics. In vitro, selitrectinib was markedly transported by mouse Abcg2 and human ABCB1, and modestly by human ABCG2. Following oral administration at 10 mg/kg, selitrectinib brain-to-plasma ratios were increased in Abcb1a/1b-/- (twofold) and Abcb1a/1b;Abcg2-/- (5.8-fold) compared with wild-type mice, but not in single Abcg2-/- mice. Testis distribution showed similar results. mAbcb1a/1b and mAbcg2 each restricted the plasma exposure of selitrectinib: With both systems absent oral availability increased by 1.7-fold. Oral administration of the ABCB1/ABCG2 inhibitor elacridar boosted plasma exposure and brain accumulation in wild-type mice to the same levels as seen in Abcb1a/1b;Abcg2-/- mice. In Cyp3a-/- mice, plasma exposure of selitrectinib over 4 hours was increased by 1.4-fold and subsequently reduced by 2.3-fold upon transgenic overexpression of human CYP3A4 in liver and intestine. The relative tissue distribution of selitrectinib remained unaltered. Thus, selitrectinib brain accumulation and oral availability are substantially restricted by ABCB1 and ABCG2, and this can be reversed by pharmacological inhibition. Moreover, oral availability of selitrectinib is limited by CYP3A activity. These insights may be useful to optimize the clinical application of selitrectinib.

A dried blood spot assay with HPLC-MS/MS for the determination of larotrectinib in mouse blood and its application to a pharmacokinetic study. Biomed Chromatogr 2020; 34:e4953. [PMID: 32706402 DOI: 10.1002/bmc.4953] [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: 06/04/2020] [Revised: 07/15/2020] [Accepted: 07/21/2020] [Indexed: 11/07/2022]
Abstract
Larotrectinib is a first-generation tropomyosin kinase inhibitor, approved for the treatment of solid tumors. In this paper, we present a validated dried blood spot (DBS) method for the quantitation of larotrectinib from mouse blood using HPLC-MS/MS, which was operated under multiple reaction monitoring mode. To the DBS disc cards, acidified methanol enriched with internal standard (IS; enasidenib) was added and extracted using tert-butyl methyl ether as an extraction solvent with sonication. Chromatographic separation of larotrectinib and the IS was achieved on an Atlantis dC18 column using 10 mm ammonium formate-acetonitrile (30:70, v/v) delivered at a flow-rate of 0.80 ml/min. Under these optimized conditions, the retention times of larotrectinib and the IS were ~0.93 and 1.37 min, respectively. The total run time was 2.50 min. Larotrectinib and the IS were analyzed using positive ion scan mode and parent-daughter mass to charge ion (m/z) transitions of 429.1 → 342.1 and 474.1 → 267.1, respectively, were used for the quantitation. The calibration range was 1.06-5,080 ng/ml. No matrix effect or carryover was observed. Hematocrit did not influence DBS larotrectinib concentrations. All of the validation parameters met the acceptance criteria. The applicability of the validated method was shown in a mouse pharmacokinetic study.
