A Randomised, Open-Label Study to Evaluate the Relative and Absolute Bioavailability of Cotadutide in Healthy Subjects

The Sponsor is developing the test medicine, cotadutide, for the potential treatment of non-alcoholic steatohepatitis (NASH) and Type 2 Diabetes Mellitus (T2DM) with chronic kidney disease. This healthy volunteer study will try to identify how two different concentrations of cotadutide are taken up by the body when dosed under the skin (subcutaneous injection). The study will also try to identify the absolute bioavailability of cotadutide (amount taken up by the body when dosed under the skin compared to an injection directly into the vein (intravenous)). This is a single-part, three-period study taking place at one non-NHS site in the UK and will involve 12 male and female (non-pregnant/non-lactating) volunteers aged 18-55. For each study period, on Day 1 volunteers will receive cotadutide as either a subcutaneous injection (into the stomach) or an intravenous injection following an overnight fast of at least 10 hours. The subcutaneous injections will be given as either a 1 mg/ml or 5 mg/ml concentration. The intravenous injection will be given as a 0.1 mg/ml concentration. Volunteers will be discharged on Day 4 and there will be a washout period of 7 days between dosing.

Blood samples will be taken at regular intervals for pharmacokinetics and safety assessments from Day -1 to discharge. Volunteers will need to return for a follow up visit 28 (±2) days post-first dose for provisional of an anti-drug antibody sample and to ensure wellbeing

The Sponsor is developing the test medicine, cotadutide, for the potential treatment of non-alcoholic steatohepatitis (NASH) and Type 2 Diabetes Mellitus (T2DM) with chronic kidney disease. NASH is a common liver disease characteristic of a damaged liver that may no longer work properly. T2DM is a condition that causes sugar (glucose) levels in the blood to become too high which can damage the blood vessels within the kidney leading to chronic kidney disease and also causing problems with eyes, heart and nerves. This healthy volunteer study will try to identify how two different concentrations of cotadutide are taken up by the body when dosed under the skin (subcutaneous injection). The study will also try to identify the absolute bioavailability of cotadutide (amount taken up by the body when dosed under the skin compared to an injection directly into the vein (intravenous)). The study will also assess the safety and tolerability of cotadutide.

Eligibility Criteria:
Inclusion Criteria:

* Provision of signed and dated, written informed consent prior to any study specific procedures.
* Healthy males or non-pregnant, non-lactating healthy females aged 18 to 55 years at the time of signing informed consent.
* Females must have a negative serum pregnancy test at screening and a negative urine pregnancy test on admission to the unit, must not be lactating, confirmed at screening and fulfil the criteria detailed in Section 9.4.
* Have a body mass index (BMI) between 18.0 and 30.0 kg/m2 inclusive and weigh at least 50 kg and no more than 100 kg inclusive.
* Must be willing and able to communicate and participate in the whole study.
* Subjects must have been received both doses of the SARS-CoV-2 vaccine.
* Must agree to adhere to the contraception requirements defined in Section 9.4

Exclusion Criteria:

* History of any clinically significant disease or disorder which, in the opinion of the investigator, may either put the volunteer at risk because of participation in the study, or influence the results or the volunteer's ability to participate in the study.
* History or presence of any disease or condition known to interfere with absorption, distribution, metabolism, or excretion of drugs.
* Evidence of renal impairment at screening, as indicated by an estimated eGFR of \<60 mL/min using the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation.
* A personal or family history of medullary thyroid carcinoma or have multiple endocrine neoplasia syndrome type 2.
* Thyroid C-cell hyperplasia (calcitonin level \> 50 ng/L) or medullary thyroid carcinoma at screening.
* History of clinically significant cardiovascular, renal, hepatic, dermatological, respirator, neurological, psychiatric or gastrointestinal disease disorder including a history of pancreatitis.
* Any clinically significant illness, medical/surgical procedure, or trauma within 4 weeks of the first administration of IMP.
* Any clinically significant abnormalities in clinical chemistry, haematology, or urinalysis results, at screening as judged by the investigator.
