The Sponsor is developing a new test medicine, AZD0780, with the aim to lower low-density lipoprotein cholesterol (LDL-C, fatty deposits) levels and cardiovascular (heart disease) risk, when given on top of standard care.

This two-part healthy volunteer study will try to identify how the test medicine is taken up, broken down and removed from the body. To help investigate this, the test medicine is radiolabelled, which means that the test medicine has a radioactive component (carbon-14; also referred as 14C) which helps us to track where the test medicine is in the body. The safety and tolerability of the test medicine will also be studied.

This study will take place at one non-NHS site, enrolling up to 8 male volunteers aged between 30 and 55 years.

The Sponsor is developing a new test medicine, AZD0780, with the aim to lower low-density lipoprotein cholesterol (LDL-C, fatty deposits) levels and cardiovascular (heart disease) risk, when given on top of standard care. High levels of LDL-C can build up on the walls of blood vessels, forming plaques which can increase the risk of heart disease and stroke.

This two-part healthy volunteer study will try to identify how the test medicine is taken up, broken down and removed from the body.

To help investigate this, the test medicine is radiolabelled, which means that the test medicine has a radioactive component (carbon-14; also referred as 14C) which helps us to track where the test medicine is in the body. The safety and tolerability of the test medicine will also be studied.

This study will take place at one non-NHS site, enrolling up to 8 male volunteers aged between 30 and 55 years.

In Part 1, volunteers will receive a single oral dose of AZD0780 on Day 1. The volunteers will then receive a single intravenous dose of [14C]AZD0780, 2.25 hours after the oral dose. Volunteers will be discharged on Day 8. Following a minimum 14 day washout period, all volunteers who participated in Part 1 of the study will be admitted to the clinical unit for Part 2. In Part 2, the volunteers will receive a single oral dose of [14C]AZD0780 on Day 1. Volunteers will be discharged on Day 11, however, if relevant radioactivity criteria have not been met, volunteers may need to remain at the clinical unit until Day 13. If relevant criteria have not been met at this point, home collections of urine and/or faeces may be required.

Volunteers will receive a follow up phone call between Day 18 and 21.

Volunteer's blood and urine and faeces will be taken throughout the study for analysis of the test medicine and for their safety.

Volunteers are expected to be involved in this study for 10 weeks from screening to the follow up call.

Inclusion Criteria:

• Provision of signed and dated, written informed consent prior to any study specific procedures.

• Body mass index (BMI) between 18.0 and 32.0 kg/m2 inclusive and weigh at least 50 kg and no more than 100 kg inclusive.
• Must have regular bowel movements (i.e. average stool production of ≥1 and ≤3 stools per day).

Exclusion Criteria:

• History of any clinically significant disease or disorder (e.g. cardiovascular, pulmonary, GI, liver, renal, neurological, musculoskeletal ,endocrine, metabolic, malignant, psychiatric, major physical impairment, skin abnormalities and glucose metabolism abnormalities) 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 clinically significant GI, hepatic or renal disease, or any other condition known to interfere with absorption, distribution, metabolism, or excretion of drugs.
• Any clinically significant illness, medical/surgical procedure, or trauma within 4 weeks of the first administration of IMP.
• History of severe allergy/hypersensitivity or ongoing allergy/hypersensitivity, as judged by the investigator or history of hypersensitivity to drugs with a similar chemical structure or class to AZD0780. Hay fever is allowed unless it is active.
• Subjects who do not have suitable veins for multiple venepunctures/cannulation as assessed by the investigator or delegate at screening
• Evidence of current SARS-CoV-2 infection
• Any clinically significant abnormalities in clinical chemistry, haematology or urinalysis as judged by the investigator. Subjects with Gilbert's Syndrome are not allowed.
• Clinically significant abnormal findings in vital signs, at screening or admission, as judged by the investigator.
• Clinically significant abnormalities on 12-lead ECG, at screening or admission, as judged by the investigator.
• Any positive result on screening for serum hepatitis B surface antigen (HBsAg), hepatitis C antibody (HCV Ab), and human immunodeficiency virus (HIV) 1 and 2 antibody
• Evidence of renal impairment at screening, as indicated by an estimated creatinine clearance (CLcr) of <80 mL/min using the Cockcroft-Gault equation
• Has received another new chemical entity (defined as a compound which has not been approved for marketing) within the 90 days prior to Day 1, or less than 5 elimination half-lives prior to Day 1, whichever is longer. Note: subjects consented and screened, but not randomised in this study or a previous Phase I study, are not excluded.
• Subjects who report to have previously received AZD0780.
• Radiation exposure, including that from the present study, excluding background radiation but including diagnostic x-rays and other medical exposures, exceeding 5 mSv in the last 12 months or 10 mSv in the last 5 years. No occupationally exposed worker, as defined in the Ionising Radiation Regulations 2017, shall participate in the study.
• Subjects who have been administered IMP in an ADME study in the last 12 months.
• Plasma donation within 1 month of screening or any blood donation/loss more than 500 mL during the 3 months prior to screening.

COVID-19 vaccines are accepted concomitant medications. Exceptions may apply, as determined by the investigator, if each of the following criteria are met: medication with a short half-life if the washout is such that no PD activity is expected by the time of dosing with IMP; and if the use of medication does not jeopardise the safety of the trial subject; and if the use of medication is not considered to interfere with the objectives of the study.
