Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 55 years
  • Men only
  • Healthy volunteers accepted
  • Adult

Who may be able to join

  • AST, ALT, alkaline phosphatase and bilirubin < or = 1.5xULN (isolated bilirubin >1.5xULN is acceptable if bilirubin is fractionated and direct bilirubin <35%). Abnormal LFT tests may be repeated once at the discretion of the Investigator. If an abnormality is repeated, the subject would not be eligible for inclusion.
  • Healthy as determined by a responsible and experienced physician, based on a medical evaluation including medical history, physical examination, laboratory tests and ECGs. A subject with a clinical abnormality or laboratory parameters outside the reference range for the population being studied may be included only if the Investigator and the GSK Medical Monitor agree that 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 subject 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. A follicle stimulating hormone (FSH) will be performed for confirmation. For this study, FSH level > 40 MlU/ml is confirmatory].
  • Male subjects with female partners of child-bearing potential must agree to use one of the contraception methods listed in Section 8.1. This criterion must be followed from the time of the first dose of study medication until the follow-up visit.
  • Body weight > or = 50 kg for men and > or = 45 kg for women and BMI within the range 18.5-30.0 kg/m2 (inclusive).
  • Capable of giving written informed consent, which includes compliance with the requirements and restrictions listed in the consent form.
  • QTcB or QTcF <450 msec or QTcB or QTcF <480 msec in subjects with Bundle Branch Block.

Who cannot join

  • Deviations from exclusion criteria are not allowed because they can potentially jeopardize the scientific integrity of the study, regulatory acceptability or subject safety. Therefore, adherence to the criteria as specified in the protocol is essential.
  • A subject will not be eligible for inclusion in this study if any of the following criteria apply:
  • Contraindications to bronchoalveolar lavage including hypercapnia >50 mm Hg, 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.
  • Current or chronic history of liver disease, or known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones).
  • A positive pre-study drug/alcohol screen. A minimum list of drugs that will be screened for include amphetamines, barbiturates, cocaine, opiates, cannabinoids, and benzodiazepines.

  • A positive test for HIV antibody.
  • History of regular alcohol consumption within 6 months of the study defined as: An average weekly intake of >14 drinks for males or >7 drinks for females. One drink is equivalent to 12 g of alcohol: 12 ounces (360 ml) of beer, 5 ounces (150 ml) of wine or 1.5 ounces (45 ml) of 80 proof distilled spirits.
  • The subject has participated in a clinical trial and has received an investigational product within the following time period prior to the first dosing day in the current study: 30 days, 5 half-lives or twice the duration of the biological effect of the investigational product (whichever is longer).
  • Use of prescription or non-prescription drugs, including vitamins, herbal and dietary supplements (including St John's Wort) within 7 days (or 14 days if the drug is a potential enzyme inducer) or 5 half-lives (whichever is longer) prior to the first dose of study medication, unless in the opinion of the Investigator and GSK Medical Monitor the medication will not interfere with the study procedures or compromise subject safety.
  • History of sensitivity to any of the study medications, or components thereof or a history of drug or other allergy that, in the opinion of the investigator or GSK Medical Monitor, contraindicates their participation.
  • History of sensitivity to pre- and post-procedure medications related to the BAL procedure such as codeine, atropine, lidocaine, midazolam, and fentanyl.
  • Where participation in the study would result in donation of blood or blood products in excess of 500 mL within a 56 day period.
  • Pregnant females as determined by positive urine hCG test at screening or prior to dosing.
  • Lactating females.
  • Unwillingness or inability to follow the procedures outlined in the protocol.

About this study

GSK2251052 is a member of a novel mechanistic and structural class of antibiotics that inhibits the bacterial enzyme leucyl tRNA synthetase (LeuRS) by forming a boron adduct with tRNA and is currently in development for the treatment of hospital acquired Gram-negative infections (including E. coli, K. pneumoniae, and Enterobacter spp.).

This is an open-label, randomized, single period, parallel-cohort pharmacokinetic study to evaluate serum and pulmonary pharmacokinetics following single dose and multiple dose administration of intravenous GSK2251052. In Cohort 1, approximately 15 healthy adult subjects will be randomized to receive a single IV dose of GSK2251052 1500 mg in the fasted state. Following the dose, bronchoalveolar lavage (BAL) fluid and serial plasma samples will be collected for determination of GSK2251052 parent and metabolite concentrations. In Cohort 2, approximately 15 healthy adult subjects will receive GSK2251052 1500 mg IV BID x 5 doses (Cohort 2). Following the last dose in the fasted state, bronchoalveolar lavage (BAL) fluid and serial plasma samples will be collected for determination of GSK2251052 parent and metabolite concentrations. Vital signs, ECGs, and adverse events will be monitored throughout the study. A follow up visit will occur 10 to 14 days after the last dose of study drug.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing GSK2251052 in people with Community-acquired Infection, run by GlaxoSmithKline at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 23 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 7 Jul 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Epithelial lining fluid (ELF)/ plasma ratios for GSK2251052 at early, mid, and late dosing interval timepoints following intravenous administration of 1500 mg q12h. (time frame: up to 3 days). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01267968, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Jul 2017.
