A Phase 1 Randomised, Double-blind, Placebo-controlled Study to Assess the Safety, Tolerability and Pharmacokinetics of DZD9008 Following Single Ascending Dose and the Effect of Low-fat Meal on Pharmacokinetics of DZD9008 in Healthy Adult Participants

This is a Phase 1, randomised, double-blind, placebo-controlled, single ascending dose sequential group study in healthy participants. This study consists of three parts: Part A (single dose escalation, SAD) , Part B (food effect, FE) and Part C (relative bioavailability, BA).

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
EXPERIMENTAL: single oral dose of DZD9008; single dose of DZD9008 (50 mg, 100 mg, 200 mg, 300 mg and 400 mg, tablet)	Drug: DZD9008; In the double blind, randomised, placebo-controlled trial (Part A - SAD), healthy adult participants will be randomized to receive DZD9008 at different dose levels. There are 5 planned dose cohorts, starting from 50 mg once daily. If tolerated, subsequent cohorts will test increasing doses of DZD9008 or matching placebo, namely 100 mg, 200 mg, 300 mg and 400 mg.; Drug: DZD9008; In Part C, healthy adult participants will be enrolled to receive a single dose of DZD9008 as suspension in period 1 and as tablet in period 2.; Drug: DZD9008; Healthy adult participants will be randomized to receive DZD9008 single dose at a defined dose under a cross-over condition with or without food (low-fat in Part B; high-fat in Part D).
PLACEBO_COMPARATOR: single oral dose of placebo; single dose of placebo (matching placebo, 50 mg, 100 mg, 200 mg, 300 mg and 400 mg, tablet)	Drug: Placebo; In the double blind, randomised, placebo-controlled trial (Part A - SAD), healthy adult participants will be randomized to receive matching placebo for DZD9008 at different dose levels. There are 5 planned dose cohorts of matching placebo for DZD9008, starting from 50 mg once daily.
EXPERIMENTAL: single oral dose of DZD9008 (300 mg, tablet)	Drug: DZD9008; In the double blind, randomised, placebo-controlled trial (Part A - SAD), healthy adult participants will be randomized to receive DZD9008 at different dose levels. There are 5 planned dose cohorts, starting from 50 mg once daily.
