Pharmacokinetic drug interactions involving vortioxetine (Lu AA21004), a multimodal antidepressant.

ABSTRACT:

Background and objective

The identification and quantification of potential drug-drug interactions is important for avoiding or minimizing the interaction-induced adverse events associated with specific drug combinations. Clinical studies in healthy subjects were performed to evaluate potential pharmacokinetic interactions between vortioxetine (Lu AA21004) and co-administered agents, including fluconazole (cytochrome P450 [CYP] 2C9, CYP2C19 and CYP3A inhibitor), ketoconazole (CYP3A and P-glycoprotein inhibitor), rifampicin (CYP inducer), bupropion (CYP2D6 inhibitor and CYP2B6 substrate), ethinyl estradiol/levonorgestrel (CYP3A substrates) and omeprazole (CYP2C19 substrate and inhibitor).

Methods

The ratio of central values of the test treatment to the reference treatment for relevant parameters (e.g., area under the plasma concentration-time curve [AUC] and maximum plasma concentration [C max]) was used to assess pharmacokinetic interactions.

Results

Co-administration of vortioxetine had no effect on the AUC or C max of ethinyl estradiol/levonorgestrel or 5'-hydroxyomeprazole, or the AUC of bupropion; the 90 % confidence intervals for these ratios of central values were within 80-125 %. Steady-state AUC and C max of vortioxetine increased when co-administered with bupropion (128 and 114 %, respectively), fluconazole (46 and 15 %, respectively) and ketoconazole (30 and 26 %, respectively), and decreased by 72 and 51 %, respectively, when vortioxetine was co-administered with rifampicin. Concomitant therapy was generally well tolerated; most adverse events were mild or moderate in intensity.

Conclusion

Dosage adjustment may be required when vortioxetine is co-administered with bupropion or rifampicin.

Project description:Vortioxetine is a novel drug for the treatment of major depressive disorder (MDD). It has been reported that vortioxetine exhibits positive effect on the acute stage of MDD, while it can effectively prevent the recurrence of MDD during the maintenance period. Currently, the results of systematic reviews on vortioxetine are insufficient since several efficacy measures, such as the 24-Items Hamilton Rating Scale for Depression (HADRS-24) total score and other safety factors have not been evaluated. Therefore, the present study aimed to evaluate the efficacy and safety of different doses of vortioxetine on the treatment of adult patients with MDD via assessing more efficacy and safety indicators. The clinical, double-blind, parallel and randomized controlled trials (RCTs) on the effect of vortioxetine on MDD were retrieved from PubMed\Medline, EBSCO, Embase, Cochrane Library, OVID, Web of Science and clinical trial registration websites from database inception to November 2022. A total of two investigators independently screened the included references and independently evaluated their quality. The meta-analysis was performed using Revman 5.0 software. The present systematic review was registered in PROSPERO (registration no. CRD42018106343). In the present study 11 RCTs were included, with a total of 4,908 adult patients with MDD. More specifically, 1,158 patients were included in the 5-mg vortioxetine group, 736 in the 10-mg group, 298 in the 15-mg group, 864 in the 20-mg group and 1,852 in the placebo group. All 11 studies were randomized, double-blinded and parallel control trials, and all publications were evaluated as high quality. The meta-analysis results showed that patients in the 5-, 10- and 20-mg vortioxetine groups exhibited significantly higher Montgomery-Asberg Depression Rating Scale (MADRS) response (≥50%) and remission (≤10%) rates compared with the placebo group (P<0.05). The pooled analysis also revealed a statistically significant change in the total score of HADRS-24, MADRS, Sheehan Disability Scale (SDS), Clinical Global Impression Scale-Improvement (CGI-I) and HADRS-24 response rate in the 10- and 20-mg vortioxetine groups compared with the placebo group (P<0.05). However, no statistically significant changes in the total score of HADRS-24, MADRS, SDS, CGI-I and HADRS-24 response rate were obtained in the 5-mg group compared with the placebo group (P>0.05). Furthermore, the most common adverse events were nausea, hyperhidrosis, insomnia and vomiting, the incidence of which was increased with higher doses of vortioxetine. Overall, the results suggested that vortioxetine administration at doses of 5-20 mg was significantly effective and safe compared with placebo in the treatment of MDD. However, 5 mg vortioxetine displayed no difference in the HADRS-24, MADRS, SDS and CGI-I total scores, and HADRS-24 response rate. Furthermore, patient treatment with increasing vortioxetine doses was associated with good tolerance and high safety. Nevertheless, more multi-center, high-quality and long-term RCTs are still needed to support the aforementioned findings.

Project description:IntroductionVortioxetine is an antidepressant primarily metabolized by the polymorphic enzyme cytochrome P450 (CYP) 2D6. A population pharmacokinetic (popPK) model of vortioxetine and its CYP2D6-dependent metabolite was recently published.ObjectiveThe aim of the current study was to assess the predictive performance of the popPK model using vortioxetine concentration measurements from a clinical setting. Furthermore, the study aimed to evaluate the ability of different CYP2D6 phenotype classification systems to provide accurate concentration predictions.MethodsOverall, 1388 patients receiving vortioxetine treatment were identified from a therapeutic drug monitoring (TDM) database in Oslo, Norway; 334 CYP2D6-genotyped patients with 502 serum concentrations of vortioxetine, analysed by a validated ultra-high-performance liquid chromatography-high-resolution mass spectrometry (UHPLC-HRMS) method, were retrospectively included. The performance of the vortioxetine popPK model was tested on the clinical data from the TDM database.ResultsOverall, the model had a good ability to predict vortioxetine concentrations measured in clinical practice, with a slight tendency to overpredict concentrations. Using simulation-based diagnostics, 76% of the prediction-corrected TDM concentrations were within the 90% prediction interval based on 1000 simulated data sets. Prediction-based diagnostics showed the best performance for CYP2D6 poor and ultrarapid metabolizers, with a median prediction error (MDPE) of 12% and 23%, respectively, while the poorest performance was observed for normal metabolizers, with an MDPE of 66%. In the comparison of different CYP2D6 phenotype classification systems, the use of differentiated activity scores for decreased function alleles did not improve the concentration predictions. Grouping the CYP2D6 genotypes into the four conventional phenotype groups provided predictions closest to the TDM measured concentrations.ConclusionTDM data provide a unique insight into real-world clinical practice with vortioxetine. The tendency of the popPK model to overpredict vortioxetine concentrations measured in TDM may be attributed to several factors, including poor treatment compliance for some patients and, to a lesser extent, lack of information on patient characteristics and misspecified CYP2D6 alleles. To optimize personalized therapy with vortioxetine, real-world clinical data sets originating from different ethnicities need to be studied in the future.
