Trial design

CTIS Part I — objectives, methods, condition coding

Main objective

Scope: Efficacy

Comparison of the effects of treatment with escitalopram, paroxetine, naltrexone, and combined treatment (escitalopram plus naltrexone) or placebo on reducing the severity of symptoms of CSBD.

Secondary objectives 4

1. Comparison of the effects of treatment with escitalopram, paroxetine, naltrexone, and combined treatment (escitalopram plus naltrexone) on characteristics of patients' daily functioning (i.e. the severity of perceived anxiety, depressiveness, impulsivity, emotion regulation skills and the level of sexual dysfunction).
2. Verification of the durability of treatment effects with escitalopram, paroxetine, naltrexone, and combination treatment with escitalopram with naltrexone or placebo in a group of patients with compulsive sexual behavior.
3. Comparison of the efficacy of different dosage approaches of escitalopram, paroxetine, naltrexone, and combination treatment of escitalopram with naltrexone or placebo in the treatment of patients with compulsive sexual behaviors
4. Comparison of the effects of treatment with escitalopram, paroxetine, naltrexone, and combination treatment with escitalopram and naltrexone on reactivity to erotic stimuli as measured by behavioral (reaction times) and neuronal (EEG evoked potentials) indicators.

6. Positive drug test result
7. Any medical contraindication to the use of escitalopram, paroxetine or naltrexone hydrochloride (according to summary of product characteristics)
8. Use of other drugs that have clinically significant or pharmacokinetic interactions with the investigational medicinal products
9. Other conditions that, in the opinion of the investigator, constitute significant contraindications to participation in the clinical trial, e.g. inability to participate in all study procedures including cognitive impairment to the extent that it is impossible to understand the study procedures and participate in the procedures
10. Any laboratory result deviating from normal values (laboratory norm) will be analyzed on an individualized basis in conjunction with the participant's clinical condition and medical history. Laboratory deviations that are the basis for the decision not to start or withhold pharmacotherapy, and thus discontinue the patient's participation in the study. 1)aspartate aminotrasferase (AST), alanine aminotransferase (ALT) - activity exceeding 3 times the upper limit of normal 2)hemoglobin < 10 g/dL, 3)leukocytes <3000/µL, 4)platelets <100,000/µL, 3)fasting glucose > 120 mg%. 4)creatinine - increase in concentration exceeding 1.5 times the upper limit of normal 5)eGFR ≤ 50 ml/min/1.73m2 6)sodium - hyponatremia < 126 mmol/L or hypernatremia > 150 mmol/L, 7)potassium - hypokalemia ≤ 3 mmol/L, hyperkalemia ≥ 5.9 mmol/L.
