Details and patient eligibility

About

The purpose of this study is to evaluate and compare the Pharmacokinetics (PK) of concomitant administration of Padsevonil (PSL) in the presence and absence of erythromycin in healthy study participants.

Enrollment: 28 patients

Sex: All

Ages: 18 to 55 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• Study participant is male or female and between 18 and 55 years of age (inclusive)
• Study participant is of a body weight of at least 50 kg for males and 45 kg for females, as determined by a body mass index (BMI) between 18 and 30 kg/m^2
• Female study participants use an efficient form of contraception for the duration of the study (unless menopausal). Hormonal contraception may be susceptible to an interaction with the Investigational Medicinal Product (IMP), which may reduce the efficacy of the contraception method. The potential for reduced efficacy of any hormonal contraception methods requires that a barrier method (preferably male condom) also be used
• Study participant has clinical laboratory test results within the local reference ranges or values are considered as not clinically relevant by the investigator and approved by the UCB Study Physician
• Study participant has Blood Pressure (BP) and pulse rate within normal range in supine position after 10 minutes of rest
• Male study participant agrees that, during the study period, when having sexual intercourse with a woman of childbearing potential, he will use an efficient barrier contraceptive (condom plus spermicide) AND that the respective partner will use an additional efficient contraceptive method

Exclusion criteria

• Study participant has previously received Investigational Medicinal Product (IMP) in this study
• Study participant has participated in another study of an IMP (or a medical device) within the previous 3 months before Screening (or within 5 half-lives for the IMP, whichever is longer) or is currently participating in another study of an IMP (or a medical device)
• Study participant has a history of drug or alcohol dependency within the previous 6 months or tests positive for alcohol (breath test) and/or drugs of abuse (urine test) at the Screening Visit or at any time during confinement
• Study participant has made a blood or plasma donation or has had a comparable blood loss (>400 mL) within the last 3 months prior to the Screening Visit
• Study participant smokes more than 5 cigarettes per day (or equivalent) or has done so within 6 months prior to the Screening Visit
• Study participant is taking any concomitant medication currently or within 2 weeks prior to the first day of dosing with the exception of paracetamol (acetaminophen)
• Study participant has any clinically relevant Electrocardiogram (ECG) finding at the Screening Visit or confinement
• Study participant has a history within the last 5 years or present condition of malignancy, with the exception of basal cell carcinoma
• Female study participant tests positive for pregnancy, plans to get pregnant during the participation in the study, or who is breastfeeding
