Details and patient eligibility


The purpose is to and to assess the mass balance recovery after a single oral dose of [14C]-BIA 9-1067 and to provide plasma, urine and faecal samples for metabolite profiling and structural identification.

Full description

This is an open-label, single-dose, single-period, non-randomised study in healthy male subjects. Subjects will be screened for eligibility to participate in the study between 28 and 2 days before dosing. Eligible subjects will be admitted to the clinical unit on the evening of the day before dosing (Day -1). Subjects will be dosed on the morning of Day 1 following an overnight fast of approximately 8 h. Blood, urine, faeces and expired air will be collected at predefined time points for mass balance and PK analysis. Subjects will remain resident in the clinic until the morning of Day 22, when they will be discharged as a group.

Single dose administration on a single occasion. The estimated duration of the study from screening until the final return visit is approximately 3.5 months.

  • Subjects who have previously been enrolled in this study;
  • History of any drug or alcohol abuse in the past 2 years;
  • Regular alcohol consumption in males >21 units per week (1 unit = ½ pint beer, 25 mL of 40% spirit or a 125 mL glass of wine);

  • Evidence of renal impairment at screening, as indicated by an estimated creatinine clearance of <90 mL/min using the Cockcroft-Gault equation;
  • History of cardiovascular, neurological, renal, hepatic, chronic respiratory or gastrointestinal disease, or clinically significant psychiatric history as judged by the investigator;
  • Serious adverse reaction or serious hypersensitivity to any drug or the formulation excipients
  • Presence or history of clinically significant allergy requiring treatment, as judged by the investigator. Hayfever is allowed unless it is active;
  • Donation or loss of greater than 400 mL of blood within the previous 3 months;
  • Subjects who are taking, or have taken, any prescribed or over-the-counter drug (other than 2 g per day paracetamol) or herbal remedies in the 14 days before IMP administration. Exceptions may apply on a case by case basis, if considered not to interfere with the objectives of the study, as agreed by the PI and sponsor's medical monitor;
  • Failure to satisfy the investigator of fitness to participate for any other reason.
