Study Details

Study Description

Brief Summary

The study will evaluate the safety, tolerability, and the pharmacokinetics (PK) of AZD7503 following multiple subcutaneous doses in healthy Japanese participants.

Condition or Disease Intervention/Treatment Phase
Phase 1

Detailed Description

This is a Phase I, randomised, single-blind, placebo-controlled study. The healthy Japanese participants will receive randomly (3:1) either AZD7503 or placebo subcutaneously.

The study will comprise of:
  • A screening period of 28 days.

  • Randomization on Day 1.

  • A 9-week Treatment Period. Dose 1 will be administered on Day 1. Dose 2 will be administered at the study site on Day 29. Dose 3 will be administered on Day 57.

  • A follow-up period of 10 week after last dose of study intervention.

  • The total duration of the study will be 23 weeks.

Outcome Measures

Primary Outcome Measures

  1. Number of participants with adverse events [From Screening (Day -28) until Follow-up Day 127 (10 weeks post last dose)]

    The safety and tolerability after multiple doses of AZD7503 in healthy Japanese participants will be evaluated.

Secondary Outcome Measures

  1. Maximum plasma drug concentration (Cmax) [Day 1, Day 2, Day 3, Day 5, Day 15, Day 29, Day 57, Day 58, and Day 59]

    The Cmax after administration of multiple doses of AZD7503 in healthy Japanese participants will be evaluated.

  2. Are under plasma concentration-time curve from time 0 to the last quantifiable concentration (AUClast) [Day 1, Day 2, Day 3, Day 5, Day 15, Day 29, Day 57, Day 58, and Day 59]

    The AUClast after administration of multiple doses of AZD7503 in healthy Japanese participants will be evaluated.

  3. Area under plasma concentration-time curve from time 0 to infinity (AUCinf) [Day 1, Day 2, Day 3, Day 5, Day 15, Day 29, Day 57, Day 58, and Day 59]

    The AUCinf after administration of multiple doses of AZD7503 in healthy Japanese participants will be evaluated.

  4. Area under plasma concentration-time curve during a dosing interval (AUCtau) [Day 1, Day 2, Day 3, Day 5, Day 15, Day 29, Day 57, Day 58, and Day 59]

    The AUCtau after administration of multiple doses of AZD7503 in healthy Japanese participants will be evaluated.

  5. Amount of analyte excreted into the urine (Ae) [Day 1, Day 2, Day 3, Day 58, and Day 59]

    The Ae after administration of multiple doses of AZD7503 in healthy Japanese participants will be evaluated.

  6. Fraction of the dose excreted unchanged in urine (Fe) [Day 1, Day 2, Day 3, Day 58, and Day 59]

    The Fe after administration of multiple doses of AZD7503 in healthy Japanese participants will be evaluated.

  7. Plasma concentration of AZD7503 [Day 1, Day 2, Day 3, Day 58, and Day 59]

    The plasma concentration after administration of multiple doses of AZD7503 in healthy Japanese participants will be evaluated.

  8. Plasma concentration of unconjugated antisense oligonucleotide (ASO) [Day 1, Day 2, Day 3, Day 58, and Day 59]

    The plasma concentration of unconjugated ASO at specified timepoints after administration of multiple doses of AZD7503 in healthy Japanese participants will be evaluated.
