About

This is a randomized, single-blind, placebo-controlled study conducted on healthy male subjects at a single study center to assess the safety, tolerability and the pharmacokinetics of AZD9977 following multiple-ascending oral doses at steady state

Full description

This is a phase 1, randomized, single-blind, placebo-controlled, single center, multiple-ascending dose sequential-group design study conducted on 45 healthy male subjects to investigate the safety, tolerability, pharmacokinetics (PK) of AZD9977, time to reach steady state, the degree of accumulation and the time dependency of the PK. The study consists of three visits: A screening period (maximum 28 days) A treatment period (subjects will be resident from 2 days before first dose of investigation medicinal product (IMP) (Day -2) until at least 36 after last dose of IMP and will be discharged on Day 9) and A follow-up visit within 5 to 7 days after last dose of IMP. This study consists of 3 Cohorts (9 subjects each). Based on the safety review committee (SRC) requirement, 2 additional cohorts may be added either to repeat a dose level or additional dose steps, if required. In each cohort, subjects will be randomized to receive AZD9977 (6 subjects) and placebo (3 subjects) oral suspension twice daily. The dose of AZD9977 in Cohort 1 will be 50 mg as starting dose and in Cohort 2 and 3 at provisional dose 150 mg and 300 mg, respectively. Each subject will receive a total of 14 oral doses of AZD9977 or placebo. Each subject will receive a single dose of IMP in the morning of Day 1 and Day 8 and twice daily doses on Day 2 to Day 7. On Day 1 and Day 8, subjects will be fasted for 10 hours before dosing until 4 hours after dosing when lunch will be served. On Day 2 to Day 6, subjects will be fasted for 10 hours before dosing until 1 hour after dosing when breakfast will be served. On Day 7, subjects will be fasted for 10 hours before dosing and until after the completion of the oral glucose tolerance test (OGTT) when breakfast will be served. For the evening dose of IMP (Days 2 to Day 7), subjects will be fasted for 2 hours before dosing until 1 hour after dosing. On all days, subjects will be allowed to drink freely until 1 hour before dosing to prevent dehydration before each morning and evening dose and water consumption could be resumed 1 hour after dosing. Dosing for each ascending dose cohort will proceed with 2 subjects in a sentinel cohort, such that 1 subject will be randomized to receive placebo and 1 subject will be randomized to receive AZD9977. The safety data from the sentinel subjects up to 72 hours post first dose will be reviewed by the principal investigator (PI) before the remaining subjects in the cohort are dosed. Following review of data from the study, the SRC may decide to adjust the length of the stay at the study site and the timing and number of assessments and/or blood samples for subsequent cohorts. The time window between the single dose and start of repeated dosing may also be adjusted. The duration of the study is approximately 6 weeks

Inclusion criteria

  • Provision of signed and dated, written informed consent before any study specific procedures.
  • Healthy male subject aged 18 to 50 years (inclusive) with suitable veins for cannulation or repeated venipuncture.
  • Have a body mass index (BMI) between 18 and 30 kg/m2(inclusive) and weigh at least 50 kg and no more than 100 kg (inclusive).
  • Provision of signed, written and dated informed consent for optional genetic and/or biomarker research. If a subject declines to participate in the genetic components of the study, there will be no penalty or loss of benefit to the subject. The subject will not be excluded from other aspects of the study.

Exclusion criteria

  • History of any clinically important disease/disorder which, in the opinion of the Investigator, may either put the subject at risk because of participation in the study/influence the results/subject's ability to participate in the study.
  • History/presence of gastrointestinal, hepatic/renal disease/any other condition known to interfere with absorption, distribution, metabolism/excretion of drugs.
  • Any clinically important illness, medical/surgical procedure or trauma within 4 weeks of the 1st administration of the IMP.
  • Any clinically important abnormalities in clinical chemistry, hematology or urinalysis results at the Screening Visit and/or admission, as judged by the Investigator and specified below: Serum potassium > 5.0 mmol/L; Hemoglobin A1c (HbA1c) > 5.7%.
  • Any positive result on screening for serum hepatitis B surface antigen, hepatitis C antibody & human immunodeficiency virus (HIV).
  • Abnormal vital signs, after 10 minutes supine rest at the Screening Visit and/or admission, defined as any of the following: Systolic BP < 90 mmHg or > 140 mmHg; Diastolic BP < 50 mmHg or > 90 mmHg; Heart rate < 45 or > 85 beats per minute (bpm).

Any clinically important abnormalities in rhythm, conduction or morphology of the resting ECG and any clinically important abnormalities in the 12-lead ECG as judged by the Investigator that may interfere with the interpretation of QTc interval changes, including abnormal ST-T-wave morphology, particularly in the CSP defined primary lead or LV hypertrophy at the Screening Visit or/and admission.

  • Prolonged QT interval corrected for HR by Fridericia's formula (QTcF) > 450 ms or shortened QTcF < 340 ms or family history of long QT syndrome.
  • PR (PQ) interval shortening < 120 ms (PR > 110 ms but < 120 ms is acceptable if there is no evidence of ventricular preexcitation).
  • PR (PQ) interval prolongation (> 240 ms intermittent second (Wenckebach block while asleep is not exclusive) or 3rd degree atrioventricular (AV) block, or AV dissociation.
  • Persistent/intermittent complete bundle branch block (BBB), incomplete bundle branch block (IBBB), or intraventricular conduction delay (IVCD) with QRS > 110 ms. Subjects with QRS > 110 ms but < 115 ms are acceptable if there is no evidence of ventricular hypertrophy or pre-excitation.
  • Known or suspected history of drug abuse in the last 12 months before the Screening Visit as judged by the Investigator.
  • Current smokers/those who have smoked/used nicotine products (including e-cigarettes) within last 3 months before the Screening Visit.
