2014년 1월 31일 업데이트: Actelion

A Phase 1, Open-label, Single Oral Dose Study to Investigate the Pharmacokinetics, Safety, and Tolerability of Cadazolid in Patients With Severe Clostridium Difficile Infection (CDI)

The study investigated the pharmacokinetics, safety, and tolerability of cadazolid in subjects with severe Clostridium difficile diarrhea (CDAD) and whether this influenced the quantity of cadazolid absorbed into the systemic circulation.

  • Clinical evidence of any relevant disease other than CDAD and/or existence of any surgical or medical condition that might interfere with the absorption, distribution, metabolism or excretion of the study drug.
  • Veins unsuitable for i.v. puncture on either arm (e.g., veins that are difficult to locate, access, or puncture; veins with a tendency to rupture during or after puncture).
  • Subjects with rare hereditary fructose intolerance, glucose-galactose malabsorption, saccharase-isomaltase deficiency or previously undiagnosed diabetes mellitus.
  • Subjects who have a life-threatening condition, which may be related to CDAD or other underlying illness.
  • Any clinically relevant electrocardiogram (ECG) abnormality at screening.
  • Subjects who were unable to swallow or have difficulty swallowing.
  • Subjects with vomiting, ileus or not passing stool.
  • Likelihood of death within 72 hours from any cause.
  • Life-threatening or fulminant CDAD (White blood cell count > 30 × 10^9/L; temperature > 40 °C; or septic shock, peritoneal signs or significant dehydration).
  • History of ulcerative colitis or Crohn's disease.
  • Loss of 250 mL or more of blood within 3 months prior to screening.
  • Positive results from the hepatitis serology, except for vaccinated subjects, at screening.
  • Positive results from the human immunodeficiency virus (HIV) serology at screening.
  • Legal incapacity or limited legal capacity at screening.
  • Any circumstances or conditions, which, in the opinion of the investigator, may affect full participation in the study or compliance with the protocol.

측정값 설명
기간
Maximum plasma concentration (Cmax) of cadazolid
기간: 144 hours
Blood samples for pharmacokinetic analysis taken immediately prior to dosing with cadazolid, and at 0.5, 1, 2, 4, 6, 8, 12, 24, 36, 48, 72, 96, 120, and 144 hours after dosing. Cmax was calculated on the basis of the blood sampling time points.
144 hours
Time to reach maximum plasma concentration (tmax) of cadazolid
기간: 144 hours
Blood samples for pharmacokinetic analysis taken immediately prior to dosing with cadazolid, and at 0.5, 1, 2, 4, 6, 8, 12, 24, 36, 48, 72, 96, 120, and 144 hours after dosing. tmax was calculated on the basis of the blood sampling time points.
144 hours
Area under the plasma concentration-time curve (AUC(0-144h)) of cadazolid
기간: 144 hours
Blood samples for pharmacokinetic analysis taken immediately prior to dosing with cadazolid, and at 0.5, 1, 2, 4, 6, 8, 12, 24, 36, 48, 72, 96, 120, and 144 hours after dosing. AUC(0-144) was calculated according to the linear trapezoidal rule using the measured concentration-time values above the limit of quantification.
144 hours
Unchanged cadazolid in urine up to Day 7
기간: 144 hours
Urine was collected into standard-weight polyethylene containers over the following time intervals: 0-12 h, 12-24 h, 24-36 h, 36-48 h, 48-72 h, 72-96 h, 96-120 h, and 120-144 h. The concentration of cadazolid was determined using validated liquid chromatography-tandem mass spectrometry assays. The amount of drug excreted in the urine was obtained by multiplying the concentration of drug by the volume of matrix collected.
144 hours
Unchanged cadazolid in faeces up to Day 7
기간: 144 hours
Faeces were collected in pre-weighed polypropylene boxes. The concentration of cadazolid was determined using validated liquid chromatography-tandem mass spectrometry assays. The amount of drug excreted in the faeces was obtained by multiplying the concentration of drug by the volume of matrix collected.

Change from baseline up to Day 7 in systolic blood pressure (SBP)
기간: 144 hours
Blood pressure (systolic and diastolic) and pulse rate were measured using an automatic oscillometric device, always on the leading arm (i.e., leading arm = writing arm). Measurements were recorded in the supine position after the subject had rested for a 5-minute period.

Treatment-emergent abnormalities were determined from standard 12-lead ECGs recorded in the supine position, after a 5-minute period of resting. An ECG abnormality was considered treatment-emergent if it was not present during the screening period and/or at time of pre-dose assessment.
