An Open-label Study in Healthy Participants to Evaluate AZD0780 as an Object or Precipitant of CYP3A4-mediated Drug-drug Interactions

Completed · Phase 1

Conditions studied: Dyslipidaemia

In brief

An open-label, fixed sequence study in healthy participants to assess the pharmacokinetics of AZD0780 when administered alone and in combination with itraconazole and carbamazepine, and to assess the pharmacokinetics of midazolam and ethinyl estradiol/levonorgestrel (EE and LNG) when administered alone and in combination with AZD0780.

Who can join

Age: 18 and older, up to 75. Sex: any. Healthy volunteers: accepted.

You may qualify if…

• Provision of signed and dated, written informed consent prior to any study-specific procedures.
• Healthy male and female participants of non-childbearing potential aged 18 to 75 years with suitable veins for cannulation or repeated venipuncture. Part 4 only: Healthy female participants of non-childbearing potential aged 18 to 75 years with suitable veins for cannulation or repeated venipuncture.
• All females must have a negative pregnancy test at the Screening Visit and on admission to the Clinical Unit.
• Females of non-childbearing potential must be confirmed at the Screening Visit by fulfilling one of the following criteria:
• Postmenopausal defined as amenorrhea for at least 12 months following cessation of all exogenous hormonal treatments and FSH levels in the postmenopausal range.
• Documentation of irreversible surgical sterilization by hysterectomy, bilateral oophorectomy, or bilateral salpingectomy but not tubal ligation or tubal occlusion.
• Sexually active fertile male participants with partners of childbearing potential must adhere to the contraception methods detailed in Appendix C 2.1 from the time of first administration of AZD0780 administration until 3 months after the study Follow-up Visit.
• Have a BMI between 18 and 35 kg/m2 inclusive and weight at least 50 kg at the Screening Visit and on admission to the Clinical Unit.

You may not qualify if…

• History of any clinically important disease or disorder which, in the opinion of the Investigator, may either put the participant at risk because of participation in the study, or influence the results or the participant's ability to participate in the study.
• History or presence of gastrointestinal, hepatic, or renal disease or any other condition known to interfere with absorption, distribution, metabolism, or excretion of drugs.
• Any prior gastrointestinal surgery which may affect absorption, eg, gastric bypass or resection.
• Any clinically important illness, medical/surgical procedure, or trauma within 4 weeks of the first administration of study intervention.
• Any laboratory values with the following deviations at the Screening Visit or on admission to the Clinical Unit. Abnormal values may be repeated once at the discretion of the Investigator.
• Any clinically important abnormalities in clinical chemistry, hematology, or urinalysis results other than those described under exclusion criterion number 5, at screening and/or admission to the Clinical Unit, as judged by the Investigator. Abnormal values may be repeated once at the discretion of the Investigator.
• Any positive result at Screening for serum HBsAg, HBcAb, HCV, or HIV.
• Any clinically significant abnormal findings in abnormal vital signs, after at least 10 minutes supine rest, at Screening and on admission to the Clinical Unit, as judged by the Investigator. Abnormal values may be repeated once at the discretion of the Investigator..
• Any clinically important abnormalities in rhythm, conduction or morphology of the resting ECG and any clinically important abnormalities in the 12-lead ECG as considered by the Investigator that may interfere with the interpretation of QTc interval changes.
• Current smokers or those who have smoked or used nicotine products (including e-cigarettes) within the previous 3 months prior to screening.
• Known or suspected history of alcohol or drug abuse or excessive intake of alcohol as judged by the Investigator.
• Positive screen for drugs of abuse, alcohol, or cotinine at Screening or on admission to the Clinical Unit.
• History of severe allergy/hypersensitivity or ongoing clinically important allergy/hypersensitivity, as judged by the Investigator or history of hypersensitivity to drugs with a similar chemical structure or class to AZD0780, itraconazole (Part 1 only), carbamazepine (Part 2 only), midazolam (Part 3 only), or EE/LNG (Part 4 only).
• Excessive intake of caffeine-containing drinks or food (eg, coffee, tea, chocolate) defined as the regular consumption of more than 500 mg of caffeine per day (eg, > 5 cups of coffee [one cup \~100 mg caffeine]; one cup of tea \~30 mg caffeine) or would likely be unable to refrain from the use of caffeine-containing beverages during confinement at the Clinical Unit.
• Use of drugs with enzyme inducing properties such as St John's Wort within 3 weeks prior to the first administration of study intervention.
• Use of any prescribed or nonprescribed medication including hormone replacement therapy, antacids or acid reducing agents (including proton pump inhibitors),analgesics (other than paracetamol/acetaminophen), herbal remedies, mega dose vitamins (intake of 20 to 600 times the recommended daily dose) and minerals during the 2 weeks prior to the first administration of study intervention or longer if the medication has a long half-life.
• Plasma donation within one month of the Screening Visit or any blood donation/blood loss > 500 mL during the 3 months prior to the Screening Visit.
• Has received another new chemical entity (defined as a compound which has not been approved for marketing) within 30 days or 5 half-lives (whichever is longest) of the first administration of the study intervention in this study. NOTE: participants consented and screened, but not enrolled/randomized in this study or a previous Phase I study, are not excluded. NOTE: All follow-up activities in a previous research study (including last study visit, unresolved AEs, or abnormal laboratory values) have to be completed prior to the Screening Visit. NOTE: Participants must be checked in VCT in the USA.
• Participants who have previously received AZD0780 within 60 days prior to Screening.
• Current/previous use of drugs that reduce or inhibit PCSK9 (approved or investigational; within 12 months of enrolment). Any current/previous use of inclisiran.
• Elevated or abnormal liver enzymes or active liver disease, or who have experienced liver toxicity with other drugs.
