Clinical Trial Summary

This study is intended to investigate the safety and tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of AZD2693, following subcutaneous (SC) administration of multiple ascending doses in participants with Non-alcoholic Steatohepatitis (NASH) with fibrosis Stage 0 to 3 and who are carriers of the patatin-like phospholipase domain-containing 3 (PNPLA3) 148M risk alleles.

Description:

This study is a double blind, randomised, placebo-controlled, multi-centre study in participants with NASH and fibrosis stage between F0 (no fibrosis) and F3 (bridging fibrosis), and who are carriers of the PNPLA3 148M risk alleles. The study will comprise of: - An optional Pre-Screening Visit may be completed to determine PNPLA3 genotype and collect minimal baseline data and participants who are carriers of the PNPLA3 148M risk allele(s) will continue the study and enter the Screening Period. - A Screening Period with a maximum of 60 days. - For participants in all Cohorts, the dosing period will be 8 weeks during which participants will be resident of the study site for Dose 1 and Dose 3. Dose 1 will have participants reside at the study site from the day prior to study intervention administration (Day -1) until at least 2 days after study intervention administration with discharge on Day 3. Dose 2 will be administered at the study site on Day 29 with no overnight stay. Dose 3 will have participants reside at the study site from the day prior to study intervention administration (Day 56) until at least 2 days after study intervention administration with discharge on Day 59. - Each participant will be followed for approximately 15 weeks post last dose. The study will be performed at up to 30 study sites in the United States (US) and up to 5 study sites in Mexico. Approximately 80 participants comprising of male and female participants of non-childbearing potential may be enrolled into the first 4 cohorts of this study in order to achieve a target of 56 to 64 evaluable participants.
