A Bioavailability and Food Effect Study of AZD5462 in Healthy Volunteers

A Randomized, 6-period, 6-treatment, Single-Dose, Crossover Study to Assess the Pharmacokinetics of AZD5462 Film-coated Tablet Formulation, to Assess the Relative Bioavailability of AZD5462 Film-coated Tablet Formulation vs Oral Solution, and to Assess the Influence of Food on the Pharmacokinetics of AZD5462 in Healthy Participants

This study will assess the pharmacokinetics of AZD5462 film-coated tablet formulation in healthy participants.

This study will consist of six treatment periods.

A total of 16 healthy male and female participants of non-childbearing potential will be randomized in this study to ensure at least 12 evaluable participants at the end of the last treatment period.

The study will comprise of a Screening Period, six Treatment Periods, and a follow-up phone call:

• A screening period of maximum 28 days.
• Six treatment periods during which participants will be residents at the study center from Day -1 until Day 17.

Each participant will receive 6 treatments.

The following treatments will be given:-

• Treatment A: Dose A of AZD5462 film-coated tablet in a fasted state.
• Treatment B: Dose A of AZD5462 film-coated tablet in a fed state.
• Treatment C: Dose B of AZD5462 film-coated tablet in a fasted state.
• Treatment D: Dose B of AZD5462 oral solution in a fasted state.
• Treatment E: Dose C of AZD5462 film-coated tablet in a fasted state.
• Treatment F: Dose C of AZD5462 film-coated tablet in a fed state.
• A follow-up phone call will take place on Day 21 (± 1 day) to record adverse events (AEs) and concomitant medication.

Inclusion Criteria:

  5. White blood cell count < 3.5 k/uL and > ULN.
  6. Hemoglobin < Lower limit of normal (LLN).

• Any clinically significant abnormalities in clinical biochemistry, hematology, or urinalysis results.

• Any clinically significant abnormal findings in vital signs after 5 minutes supine rest, at screening or admission defined as any of the following:

  1. Systolic Blood pressure (BP) < 90 mmHg or ≥ 140 mmHg.
  2. Diastolic BP < 50 mmHg or ≥ 90 mmHg.
  3. Heart rate < 50 bpm or > 90 bpm.

• Any clinically important abnormalities in rhythm, conduction or morphology of the resting 12-lead Electrocardiogram (ECG) at screening or admission.
