E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Primary: To evaluate whether a single nebulised dose of GSK2862277 prevents peri-operative lung injury compared to placebo, as assessed by measurement of pulmonary vascular permeability. |
|
E.2.2 | Secondary objectives of the trial |
- To evaluate whether a single nebulised dose of GSK2862277 prevents perioperative lung injury compared to placebo, as assessed by measurement of pulmonary oedema.
- To evaluate the safety and tolerability of GSK2862277 administered preoperatively.
- To evaluate whether a single nebulised dose of GSK2862277 prevents perioperative lung injury compared to placebo, as assessed by degree of hypoxaemia.
- To evaluate differences in expression profile of BAL biomarkers from both ventilated and collapsed lungs immediately after surgery.
- To evaluate the effect of a single IH dose of GSK2862277 compared to placebo, on attenuating lung and distal organ injury over the post-operative period.
- To describe plasma pharmacokinetics of a single inhaled dose of GSK2862277.
- To quantify the concentration of GSK2862277 in BAL and to compare to plasma levels of GSK2862277.
- To evaluate the levels and specificity of any anti-drug antibodies formed following dosing with GSK2862277. |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Subject has a planned elective transthoracic oesophagectomy
2. Male or female between 18 and 80 years of age inclusive, at the time of signing the informed consent.
3. Capable of giving written informed consent, which includes compliance with the requirements and restrictions listed in the consent form.
4. 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 [in questionable cases a blood sample with simultaneous follicle stimulating hormone (FSH) > 40 MlU/ml and estradiol < 40 pg/ml (<147 pmol/L) is confirmatory]. Females on hormone replacement therapy (HRT) and whose menopausal status is in doubt will be required to use one of the contraception methods listed in the appendix of this concept protocol if they wish to continue their HRT during the study. Otherwise, they must discontinue HRT to allow confirmation of post-menopausal status prior to study enrollment. For most forms of HRT, at least 2-4 weeks should elapse between the cessation of therapy and the blood draw; this interval depends on the type and dosage of HRT.
Following confirmation of their post-menopausal status, they can resume use of HRT during the study without use of a contraceptive method.
5. Liver parameters according to the thresholds below: AST and ALT < 3xULN; alkaline phosphatase and bilirubin =< 1.5xULN (isolated bilirubin >1.5xULN is acceptable if bilirubin is fractionated and direct bilirubin <35%).
6. QTcB or QTcF <= 450 msec at screening. Either QTcB or QTcF, machine or manual over-read can be used. This applies to both males and females. The QT correction formula used to determine inclusion and discontinuation for an individual subject should be the same throughout the study.
- Based on average QTc value of triplicate ECGs obtained over a brief recording period.
It is recognised that in some subjects the QTc may be variable over time (e.g. intermittent use of a pacemaker; junctional rhythm). Inclusion of these subjects should be discussed with the medical monitor prior to enrolment. |
|
E.4 | Principal exclusion criteria |
1. Positive screening test for pre-existing antibodies that bind GSK2862277.
2. Current evidence or history of pneumonia within 14 days before dosing.
3. Diagnosis of chronic respiratory disease with a forced expiratory volume in one second (FEV1) less than 50% predicted or resting oxygen saturations of less 92%.
4. 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.
5. The subject 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).
6. Use of corticosteroids (IV, oral or IM) at a dose of > 10 mg/day prednisolone (or equivalent) within 14 days prior to dosing, or anti-Tumor Necrosis Factor (anti-
TNF) or anti-Interleukin-1 (anti-IL1) within 60 days prior to dosing.
Criteria Based Upon Medical Histories
1. History or current evidence of clinically significant renal disease, diabetes mellitus/metabolic syndrome, hypertension, peripheral vascular disease or any other
clinically significant respiratory, cardiovascular, neurological, endocrine, or hematological abnormalities that are uncontrolled on permitted therapy. Significant
is defined as any disease that, in the opinion of the Investigator, would put the safety of the patients at risk through study participation, or which would affect the safety analysis or other analysis if the disease/condition exacerbated during the study.
2. Current or chronic history of liver disease, or known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones).
3. History of regular alcohol consumption within 6 months of the study, defined as:
- an average weekly intake of >28 units for males or >14 units for females. One unit is equivalent to 8 g of alcohol: a half-pint (~240 ml)
of beer, 1 glass (125 ml) of wine or 1 (25 ml) measure of spirits.
Criteria Based Upon Diagnostic Assessments
1. Screens positive for Hepatitis B surface antigen, Hepatitis C antibody
2. Known Human Immunodeficiency Virus (HIV) positive; testing will be conducted in accordance with local procedures
3. Tests positive for Mycobacterium tuberculosis using QuantiFERON Gold Test.
Other Criteria
1. Subject has received a live attenuated vaccine(s) within 3 weeks of randomisation or will require vaccination with a live attenuated vaccine prior to the end of the study (Day 28).
2. Unwillingness or inability to follow the procedures outlined in the protocol.
3. Subject is mentally or legally incapacitated. |
