Summary

This study will assess the safety, tolerability, immunogenicity, and pharmacokinetics (PK), and explore the pharmacodynamics (PD) following single ascending dose administration and repeat dose administration in healthy subjects and patients with Crohn's disease.

Detailed description

This is a Phase I, randomised, double-blind, placebo controlled study in healthy male and female subjects as well as patients with Crohn's disease performed at a single study centre. This study is comprised of 3 parts: Part 1 (sub-parts 1a and 1b), Part 2, and Part 3 (sub-Parts 3a and 3b). * Part 1a: This is a First-In-Human (FIH), single ascending dose (SAD) sequential group study. Up to 7 dose levels of AZD7798 are planned to be investigated. Depending on the findings, an additional dose may be added. Up to 80 healthy subjects are planned to be included. Eight subjects will participate in each single dose cohort. Within each cohort, 6 subjects will be randomised to receive AZD7798, and 2 subjects will be randomised to receive placebo. Each subject will be enrolled up to 113 days (approximately 16 weeks). * Part 1b: Up to 8 subjects will be randomised to receive a planned dose of AZD7798 (up to 6 subjects) or placebo (up to 2 subjects) on Day 1 and Day 15. This cohort is planned to start after completion of the single dose level cohort in Part 1a. Each subject will be enrolled up to 149 days (approximately 21 weeks). * Part 2: Up to 8 patients will be randomised (2:1:1) into 1 of 3 strata and receive: * Stratum 1: AZD7798 on Day 1 and Day 15 (up to 4 patients). * Stratum 2: Placebo on Day 1 and AZD7798 on Day 15 (up to 2 patients). * Stratum 3: AZD7798 on Day 1 and placebo on Day 15 (up to 2 patients). Each subject will be enrolled up to 149 days (approximately 21 weeks). * Part 3: Subjects will be randomised to AZD7798 or placebo in a ratio of 3:1 (up to 6 subjects will receive AZD7798 and up to 2 subjects will receive placebo).
