Study summary

The purpose of this study is to evaluate the safety and pharmacokinetics/pharmacodynamics of co-administration of Clomipramine HCl 15mg and Sildenafil citrate 100mg compared to the effects after single oral administration in Korean healthy male volunteers.

Read the detailed description

Clomipramine is a dibenzazepine-derivative tricyclic antidepressant (TCA) and is a potent inhibitor of serotonin and norepinephrine reuptake. Clomipramine may be used in a variety of indications. Condencia Tab contains low dose of 15mg of clomipramine HCl as an active ingredient, which is newly approved to market for the treatment of premature ejaculation.

This study is a prospective, randomised, open-labeled, 6-sequence, 3-period, 3-treatment, crossover, and single-center clinical trial. A total of 30 healthy male volunteers will be enrolled and randomised into one among 6 groups (5 subjects per a group). The safety and PK/PD characteristics of co-administration of Clomipramine HCl and Sildenafil citrate will be investigated closely compared to the effects after single dose administrations.

What researchers measure

Primary outcomes

  1. The systemic exposure measured as area under the curve (AUC)

    Time frame: From Day 1(dosing) to Day 4(72hrs)

  2. The maximum concentration (Cmax)

    Time frame: From Day 1(dosing) to Day 4(72hrs)

Secondary outcomes

  1. Pharmacokinetic parameters except the primary endpoints

    Including Tmax, T1/2, AUCnorm, Cmax norm, CL/f and Cmax/AUC

    Time frame: From Day 1(dosng) to Day 4(72hrs)

  2. The maximum change of systolic blood pressures within 12hrs after dosing

    At supine and upright positions

    Time frame: Day 1(dosing) to Day 2(12hrs)

  3. Adverse events

    Time frame: For 3 Weeks after dosing

  4. The maximum change of dystolic blood pressure within 12hrs after dosing

    at supine and upright positions

    Time frame: From Day 1(dosing) to Day 2(12hrs)

  5. The maximum change of heart rates within 12 hours after dosing

    At supine and upright positions

    Time frame: From Day 1(dosing) to Day 2(12hrs)

  6. The rate of the subjects who experienced the clinically significant change of blood pressures

    Clinically significant changes will be classified into 4 groups: SBP change \>=30 or 20 mmHg, DBP change \>= 20 or 10 mmHg (at supine and upright positions)

    Time frame: From Day 1(dosing) to Days 2(12hrs)
