Trial overview
Official title: An Open-label Study To Evaluate Plasma and Pulmonary Pharmacokinetics Following Intravenous Administration of GSK2140944 in Healthy Adult Subjects (BTZ116666)
Trial description: Antimicrobial penetration can be assessed through evaluation of antimicrobial concentrations in various lung compartments, including bronchial mucosal tissue, epithelial lining fluid (ELF), and alveolar macrophages (AM). Antimicrobial concentrations determined in ELF and alveolar macrophages represent an ideal estimate of concentrations at the site of infection and can be accessed via bronchoalveolar lavage (BAL). However sampling of antimicrobial concentrations via BAL is not routine in clinical practice due to its complex methodology and poor patient tolerability. This study will evaluate intrapulmonary and plasma pharmacokinetics of GSK2140944 after single IV dose in adult healthy volunteers. This is a Phase I, open-label study to evaluate plasma and pulmonary pharmacokinetics following intravenous administration of GSK2140944 in healthy adult participants. Part A will evaluate the single dose PK profiles. Part B is optional and will only be conducted if necessary. Each part will consist of a maximum of 6 cohorts. In Part A, only 4 of the 6 cohorts will be dosed initially; cohorts 5 and 6 are optional and will only be dosed if additional time-points are necessary to adequately model the pulmonary pharmacokinetic profile.

Accepts healthy volunteers
Yes
- Aspartate aminotransferase (AST), Alanine aminotransferase (ALT), alkaline phosphatase and bilirubin <=1.5x Upper limit of normal (ULN) (isolated bilirubin >1.5xULN is acceptable if bilirubin is fractionated and direct bilirubin <35%).
- Healthy as determined by a responsible and experienced physician, based on a medical evaluation including medical history, vital signs, electrocardiograms (ECGs), physical examination, and laboratory tests. A participant with a clinical abnormality or laboratory parameters outside the reference range for the population being studied may be included if in the Investigator’s judgement the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures.
- Contraindications to bronchoalveolar lavage including hypercapnia >50 millimeters of mercury (mm Hg), known or suspected intolerability to medications necessary for bronchoscopy, refractory hypoxemia, reactive airway disease or asthma, unstable angina or acute myocardial infarction in the last 6 months, heart failure, and severe hemostatic alterations.
- A positive pre-study Hepatitis B surface antigen or positive Hepatitis C antibody result within 3 months of screening or positive Human Immunodeficiency Virus (HIV) antibody.
Inclusion and exclusion criteria
Inclusion criteria:
- Aspartate aminotransferase (AST), Alanine aminotransferase (ALT), alkaline phosphatase and bilirubin <=1.5x Upper limit of normal (ULN) (isolated bilirubin >1.5xULN is acceptable if bilirubin is fractionated and direct bilirubin <35%).
- Healthy as determined by a responsible and experienced physician, based on a medical evaluation including medical history, vital signs, electrocardiograms (ECGs), physical examination, and laboratory tests. A participant with a clinical abnormality or laboratory parameters outside the reference range for the population being studied may be included if in the Investigator’s judgement the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures.
- Male or female between 18 and 55 years of age inclusive, at the time of signing the informed consent. A female participant is eligible to participate if she is of non-childbearing potential defined as pre-menopausal females with a documented tubal ligation or hysterectomy; or postmenopausal defined as 12 months of spontaneous amenorrhea. To confirm post-menopausal status, a blood sample for simultaneous follicle stimulating hormone (FSH) > 40 milli-international units per milliliter (MlU/ml) and estradiol < 40 picrograms (pg)/ml (<147 picromoles/Liter [pmol/L]) is confirmatory. Male participant with female partners of child-bearing potential must agree to use one of the contraception methods listed as per protocol. This criterion must be followed from the time of the first dose of study medication until the final follow-up visit.
- Body weight >= 50 kg and Body mass index (BMI) within the range 19 – 31Kilograms/meter^2(kg/m^2) (inclusive).
