NCT05210140

Brief Summary

The aims of this study are to:

  1. 1.Determine the proportion of participants who are underdosed or overdosed under recommended dosing regimen of escitalopram for the depression treatment (10 mg/day)
  2. 2.Determine and quantify clinical benefits of personalized escitalopram dosing regimen based on the escitalopram blood level monitoring
  3. 3.Retrospectively estimate whether the information on CYP2C19 genotype is useful in the prediction of escitalopram blood level.

Outcome Measures

Primary Outcomes (2)

  • Change from Baseline Depression severity score at week 8

    Measured with clinician reported 21-item Hamilton rating scale for depression (HAM-D). Scale gives a score from 0 to 52 where higher score represents higher depression severity and worse outcome.

    8 Weeks

  • Adverse drug reaction severity score at week 8

    Measured with clinician reported UKU (Udvalg for Kliniske Undersogelser) side effect rating scale. Scale gives summary score from 0 to 3 where higher scores correspond to the greater side-effects severity and worse outcome.

    8 Weeks

Secondary Outcomes (4)

  • Number of participants with escitalopram plasma concentrations outside the therapeutic window

    at Week 2

  • Retrospectively determined regression formula for prediction of escitalopram plasma levels at Vk based on CYP2C19 metabolizer status

    8 Weeks

  • Change from Baseline Depression severity score at week 4

  • Adverse drug reaction severity score at week 4

Study Arms (2)

Standard dose

Patients are allocated to this group at visit V1 if 10 mg/day escitalopram treatment resulted in optimal escitalopram exposure (25-50 ng/ml) as measured at VK. These patients will continue their treatment with 10 mg/day during the V1-V2 period.

Drug: Escitalopram

Adjusted dose

Patients are allocated to this group at visit V1 if 10 mg/day escitalopram dose resulted in to high (\>50 ng/ml) or to low (\<25 ng/ml) escitalopram exposure, as measured at VK. These patients will be treated with the adjusted escitalopram dose, different from 10 mg/day, during the V1-V2 period.

Drug: Escitalopram

Interventions

Escitalopram, a selective serotonin reuptake inhibitor (SSRI), is commercially known as ELORYQA®, Elicea®, Escital®,PRAMES® or Lata® in Serbia. The recommended dose for Major depressive disorder is 10mg/day. Based on the individual response, dose can be adjusted and the maximum dose is 20 mg/day; 5 mg/day dose is also available. Escitalopram is also indicated for treatment of Obsessive-compulsive disorder, Generalized anxiety disorder, Social anxiety disorder (Social phobia) and Panic disorder (with or without agoraphobia) by Medicines and Medical Devices Agency of Serbia. In known CYP2C19 poor metabolizers, initial dose should be 5mg/day during first 2 weeks, and based on the individual response it can be increased up to maximum of 10 mg of escitalopram per day, according to the guidelines of Medicines and Medical Devices Agency of Serbia.

Biospecimen

Retention: SAMPLES WITH DNA

Two ml of plasma for the measurement of drug concentrations at visits at week 2, week 4 and week 8. Two ml of serum for biochemical analyses of liver and kidney function, cortisol levels, lipid status and glucose levels at visits at week 2, week 4 and week 8. "Buffy coat" taken from the 5 ml blood sample for DNA extraction and CYP2C19 genotyping, at any visit.
