Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Investigational Product (IP): ELVN-002
Dosage Form: Capsule
Mode of Administration: Oral

Part B (FE): Part B (FE) will be conducted only if the Part A (SAD) FE Cohort shows a difference in safety or PK data between the fasted and fed states and the SRC decides to enrol additional participants.
Six participants will be admitted to the site on Day -1 and fast for at least 10 hours before dosing. On dosing day (Day 1), participants will take ELVN-002 orally with 240 mL of water and will continue fasting for at least 4 hours after dosing (water intake will be permitted at 1 hour after dosing). Participants will remain confined, and safety will be monitored (Day 2 to Day 8).
On Day 9, participants will fast for at least 10 hours before dosing. On dosing day (Day 10 ± 1), participants will consume a standardised (high-fat, high-calorie) breakfast within 30 minutes, and will then receive ELVN-002 orally at the selected dose with 240 mL of water. Participants will remain fasting for at least 4hours after dosing (water intake will be permitted 1 hour after dosing).
A high-fat (approximately 50 percent of total caloric content of the meal) and high-calorie (approximately 800 to 1000 calories) meal is recommended as a test meal for food-effect studies.
This test meal should derive approximately 150, 250, and 500-600 calories from protein, carbohydrate, and fat, respectively.

Summary
Brief summary
This study is investigating a new cancer treatment drug, ELVN-002, that may be used for patients with lung cancer.

Who is it for?
You may be eligible for this study if you are a healthy adult aged 18 to 60 years old. Please note that this study will not be enrolling patients with lung cancer.

Study details
This registration is for Part B of a 3-part study investigating ELVN-002.

Participants in this study will receive two doses of ELVN-002 on separate days. ELVN-002 will be given to you in capsule form. During the first dosing period, participants will be asked to fast for 10 hours prior to receiving a single dose of ELVN-002. Participants will then be asked to continue to fast for another 4 hours after dosing. Nine days after this first dose, participants will then be asked to consume a high fat breakfast before being given a single dose of ELVN-002.

Total participation will last up to 13 ± 1 to the clinic for physical examination and vitals assessments and to collect blood and urine samples.

It is hoped that this research will help determine the dose that ELVN-002 can be safely given to patients with lung cancer.
