Brief summary

GSK3335065 is being developed as a treatment for acute pancreatitis with the intent of reducing 3-hydroxykynurenine (3HK) levels to the normal range (or lower) and maintaining them at this level throughout the treatment period. This study will utilize an adaptive design and is divided into 3 parts. Part A will consist of 8 cohorts (1-8) and is Single Ascending Dose (SAD) of GSK3335065 by IV bolus in males. Part B will be initiated after completion of dosing in Part A. It will involve ascending IV bolus doses of GSK3335065 followed by IV constant infusion for 7 days in males and will consist of four cohorts (9-12). Part C consists of a single dose of GSK3335065 by IV bolus (cohort 13), and a single dose followed by continuous infusion over 7 days (cohort 14) in females of non-child bearing potential (WONCBP). Total 64 subjects will be evaluated in the study of which Part A will include 16 healthy male subjects, Part B will include 32 healthy male subjects and Part C will include 16 WONCBP. In Part A, cohorts 1 and 2 will last up to 19 weeks and cohorts 3 to 8 will last up to 7 weeks and Part B will last up to 13 weeks. In Part C cohort 7 will last up to 7 weeks and cohort 8 will last for 13 weeks.

Interventions

DRUGGSK3335065

GSK3335065 is being developed as a treatment for acute pancreatitis with the intent of reducing 3-hydroxykynurenine (3HK) levels to the normal range (or lower) and maintaining them at this level. GSK3335065 is a solution and will be administered as intravenous injection and infusion with dose strength of 5 milligram (mg)/mL that may be diluted in 0.9% weight by volume (w/v) sodium chloride.

Recruitment details

This was planned to be a 3 part, dose escalation study; however, the study was terminated during Part A (Cohort 3) because a relationship between GSK3335065 and ventricular tachycardia in a participant could not be excluded. Hence, participants were not recruited in Cohorts 4 to 8 of Part A; Part B and Part C were not initiated.

Pre-assignment details

A total of 55 participants were screened of which 33 failed screening and 4 were kept in reserve but not used. A total of 18 participants were enrolled in the study. The study was conducted in the United Kingdom. Placebo arms across similar dosing strategies were combined as pre-specified in reporting and analysis plan.

Primary

Number of Participants With Abnormal Electrocardiogram (ECG) Findings-Part A

Triplicate 12-lead ECGs were obtained using an ECG machine that automatically calculated the heart rate and measured PR, QRS, QT, QT interval corrected using Fridericia's formula (QTcF) and Bazett's QT interval corrected for heart rate (QTcB). ECG measurements were preceded by at least 5 minutes rest for the participant in a semi-recumbent position.

Primary

Number of Participants With Abnormal Vital Signs-Part A

Vital signs including systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate, respiration rate and temperature were measured in a semi-recumbent position with a completely automated device preceded by at least 5 minutes of rest for the participant in a quiet setting without distractions. Participants are counted in the worst case category that their value changes to (low, normal or high), unless there is no change in their category. Participants whose value category was unchanged (e.g., High to High), or whose value became normal, are recorded in the To Normal or No Change category. Data for worst case post-Baseline relative to Baseline is presented. Baseline was defined as the latest pre-dose assessment. Placebo arms across similar dosing strategies were combined as pre-specified in reporting and analysis plan.

Number of Participants With Abnormal Vital Signs-Part B

Vital signs including SBP, DBP, heart rate, respiration rate and temperature were planned to be measured in a semi-recumbent position with a completely automated device preceded by at least 5 minutes of rest for the participant in a quiet setting without distractions.

Time frame: Up to Day 34

Population: All Subjects Population. Data was not collected as no participants were enrolled in Part B of the study.

Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs)-Part A

An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of a study treatment, whether or not considered related to the study treatment. An SAE is defined as any untoward medical occurrence that, at any dose: results in death; is life-threatening; requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent disability/incapacity; is a congenital anomaly/birth defect; other important medical events that may jeopardize the participant or may require medical or surgical intervention to prevent one of the other outcomes listed before. All Subject Population comprised of all participants randomized to treatment who received at least one dose of study treatment. AEs and SAEs were collected from admission until follow-up. Placebo arms across similar dosing strategies were combined as pre-specified in reporting and analysis plan.

Time frame: Up to Day 22

Population: All Subject Population. Data was not collected for Cohorts 4 to 8 as no participants were enrolled.

Change From Baseline in Levels of Tryptophan Metabolites-Part A (Cohort 1 and 2)

Blood samples were collected to measure the kynurenine-3-monooxygenase (KMO) enzyme inhibition by determining the levels of the biomarkers Kynurenine (Kyn) and 3-hydroxykynurenine (3-HK). Baseline was the average of all pre-dose measurements (Day 1 \[pre-dose at 1 hour and 30 minutes\]). Change from Baseline was calculated as value at the specified time point minus the Baseline value.

Time frame: Baseline, 6, 15 and 30 minutes, 1, 1.5, 2, 3, 4.5, 6, 9, 12, 15, 18, 24, 30, 36, 42, 48, 60 and 72 hours post-dose

Population: All Subject Population. Only those participants with data available at the specified time points were analyzed (indicated by n=X in category titles). Data was not collected for placebo arms of Cohorts 1 and 2.

Change From Baseline in Levels of Tryptophan Metabolites-Part A (Cohorts 3 to 8)

Blood samples were collected to measure the KMO enzyme inhibition by determining the levels of the biomarkers Kyn and 3-HK. Baseline was the average of all pre-dose measurements (Day -1 \[pre-dose at 16 hours, 14 hours, 12 hours and 10 hours\] and Day 1 \[pre-dose at 30 minutes and 2 hours\]). Change from Baseline was calculated as value at the specified time point minus the Baseline value.

Time frame: Baseline, 6, 15 and 30 minutes, 1, 1.5, 2, 3, 4.5, 6, 9, 12, 15, 18, 24, 30, 36, 42, 48, 60, 72, 84, 96, 108, 120, 132, 144, 156 and 168 hours post-dose

Population: All Subject Population. Data was not collected for Cohorts 4 to 8 as no participants were enrolled. Only those participants with data available at the specified time points were analyzed.
