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.


Eligibility criteria: Inclusion Criteria

* Subjects who are overtly healthy as determined by medical evaluation including medical history, physical examination, laboratory tests, and cardiac monitoring.
* A subject with a clinical abnormality or laboratory parameter(s) which is/are not specifically listed in the inclusion or exclusion criteria, outside the reference range for the population being studied may be included only if the investigator in consultation with the Medical Monitor if required agree and document that the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures.
* Body weight greater than 50 kilogram (kg) and body mass index (BMI) within the range 18.5 - 32 kilogram per meter square (kg/m\^2).
* Length of time required for abstinence or use of contraceptives should take into account the reproductive toxicity profile including genotoxicity and teratogenicity, the size of the molecule, and the number of doses. Male subjects must agree to use contraception during the treatment period and for at least 2 days after the last dose of study treatment and refrain from donating sperm during this period. Only female subjects of WONCBP are eligible to participate.
* Capable of giving signed informed consent.
