A Study to Assess the Mass Balance Recovery, Metabolite Profile and Metabolite Identification of [14C]AZD9833

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 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 or ongoing clinically significant visual disturbances including but not limited to visual hallucinations, migraine with visual symptoms, blurred vision, frequent floaters/flashes associated with other symptoms such as dizziness
• - Any clinically significant abnormalities in clinical chemistry, haematology, or urinalysis results, at screening as judged by the Investigator
• - Any clinically significant abnormal findings in vital signs at screening as judged by the Investigator, including systolic BP <100 mmHg, diastolic BP <50 mmHg or heart rate <50 bpm. Vital signs outside these limits can be repeated once for confirmation
• - Any clinically significant abnormalities on 12-lead ECG at screening, as judged by the Investigator, including non-sinus rhythms, PR interval <120 msec or >220 msec, ventricular rate <50 bpm or >100 bpm, QRS interval >120 msec, or QTcF >470 msec as a mean of triplicate. ECGs can be repeated once in triplicate if parameters are outside these limits for confirmation
• - Evidence of renal impairment at screening, as indicated by an estimated creatinine clearance (CLcr) of <60 mL/min/1.73m2 using the Cockcroft-Gault equation
• - 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 antibodies
• - Has received another new chemical entity (defined as a compound which has not been approved for marketing) within 4 weeks prior to Day 1, or less than 5 elimination half-lives + 6 days prior to Day 1, whichever is longer. Note: subjects consented and screened, but not administered IMP in this study or a previous Phase I study, are not excluded
• - Plasma donation within 1 month of screening or any blood donation/loss more than 500 mL during the 3 months prior to screening
• - 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 AZD9833. Hay fever is allowed unless it is active
• - Any known or suspected hypersensitivity or contraindication to the components of the study drug, AZD9833, judged to be clinically relevant by the investigator
• - Current smokers or those who have smoked or used nicotine products (including e-cigarettes) within the 3 months prior to screening
• - A confirmed breath carbon monoxide reading of greater than 10 ppm at screening or admission
• - Positive screen for drugs of abuse at screening or on each admission to the study centre
• - Regular alcohol consumption >14 units per week (1 unit = ½ pint beer, or a 25 mL shot of 40% spirit, 1.5 to 2 units = 125 mL glass of wine, depending on type)
• - A confirmed positive alcohol breath test at screening or admission
• - Subjects who are taking, or have taken:
• (a) any prescribed or over-the-counter drug (other than up to 4 g of paracetamol per day ) or herbal remedies in the 14 days before IMP administration or longer if the medication has a long half-life. 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
• (b)atropine or atropine containing drugs, in the 14 days before IMP administration
• (c)Systemic oestrogen-containing hormone replacement therapy in the 6 months prior to IMP administration
• - Use of drugs with enzyme-inducing properties such as St John’s Wort within 3 weeks or 5 half-lives (whichever is longer) or any drugs with a known risk, potential risk or conditional risk for QTca prolongation as defined and outlined in the Credible Meds website within 4 weeks prior to Day 1
• - Subjects who do not agree to avoid the to use warfarin or phenytoin (and other coumarin-derived vitamin K antagonist anticoagulants) for 2 weeks after administration of IMP
• - Excessive intake of caffeine-containing drinks or food (e.g., coffee, tea, chocolate) as judged by the Investigator. Excessive intake of caffeine defined as the regular consumption of more than 600 mg of caffeine per day (e.g., >5 cups of coffee) or would likely be unable to refrain from the use of caffeine-containing beverages during confinement at the clinical unit
• - Involvement of any Astra Zeneca, Quotient or study site employee or their close relatives
• - Subjects who report to have previously received AZD9833 in the last 12 months
• - Judgment by the Investigator that the volunteer should not participate in the study if they have any ongoing or recent (i.e., during the screening period) minor medical complaints that may interfere with the interpretation of study data or are considered unlikely to comply with study procedures, restrictions, and requirements
• - Evidence of current SARS-CoV-2 infection
• - 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
• - Vulnerable subjects, e.g., kept in detention, protected adults under guardianship, trusteeship, or committed to an institution by governmental or juridical order
• - Subjects who do not have suitable veins for multiple venepunctures/cannulation as assessed by the Investigator or delegate at screening
• - Subjects with an anticipated need for major surgery and/or any surgery requiring general anaesthesia during the participation in the study (which may entail administration of atropine in an anaesthetic context)
• - Failure to satisfy the Investigator of fitness to participate for any other reason
