Description of intervention(s) / exposure
Treatment: Drugs - VRN110755
Treatment: Drugs - Rabeprazole

Experimental: Sequence 1: Fasted ? Fed ? Fed with PPI - Participants in this sequence will receive VRN110755 80 mg orally under the following conditions across three periods:

Period 1: Fasted state Period 2: Fed state (standard high-fat meal) Period 3: Fed state after 5 days of rabeprazole 20 mg daily

Experimental: Sequence 2: Fed ? Fasted ? Fasted with PPI - Participants in this sequence will receive VRN110755 80 mg orally under the following conditions across three periods:

Period 1: Fed state (standard high-fat meal) Period 2: Fasted state Period 3: Fasted state after 5 days of rabeprazole 20 mg daily


Treatment: Drugs: VRN110755
VRN110755 is an investigational EGFR inhibitor administered as an 80 mg oral capsule. It will be given to all participants under fasted, fed, and PPI pre-treated conditions across three periods in a crossover design.

Treatment: Drugs: Rabeprazole
Rabeprazole 20 mg will be administered orally once daily for 5 days prior to VRN110755 dosing in Period 3. This is to assess the effect of increased gastric pH (via proton pump inhibition) on the pharmacokinetics of VRN110755.
