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 C of a 3-part study investigating ELVN-002. There are two arms in Part C of the study. Participants enrolled into the CYP3A4 Inhibitor Arm will receive two single dose of ELVN-002 (in capsule form) on separate days. First dose on Day 1 and second dose on Day 7. Participants will also be asked to take a daily dose of itraconazole for 7 days (from Day 4- Day 10). Participants enrolled into the CYP3A4 Inducer Arm will receive two single dose of ELVN-002 (in capsule form) on separate days. First dose on Day 1 and second dose on Day 17. Participants will also be asked to take phenytoin 3 times daily for 17 days (from Day 3- Day 19). Total participation will last up to 10 days for CYP3A4 Inhibitor Arm and 20 days for CYP3A4 Inducer Arm 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.

CYP3A4 inhibitor arm: The participants will be admitted to the study site on Day -1 and will fast for at least 10 hours before dosing. On dosing day (Day 1), participants will take ELVN-002 90 mg orally with240 mL of water and remain fasting for 4 hours after dosing (water intake will be permitted 1 hour after dosing). Participants will then consume a standard meal within 30 minutes. From Day 4 to Day 9 (6 days), participants will receive itraconazole 200 mg once daily in the morning after consuming a standard meal. On Day 6, participants will fast for at least 10 hours before the 2nd dose of ELVN-002. On dosing day (Day7), participants will take ELVN-002 90 mg orally and remain fasting for 4 hours after dosing (water intake will be permitted 1 hour after dosing). Participants will then consume a standard meal and then immediately receive itraconazole 200 mg. Please note for CYP3A4 inhibitor arm, it is recommended to take itraconazole with food. Standard meal provided by site. CYP3A4 inducer arm: Twelve eligible participants will be admitted to the study site on Day -1 and will fast for at least 10 hours before dosing. On dosing day (Day 1), participants will take ELVN-002 360 mg orally with 240 mL of water and will remain fasting for 4 hours after dosing (water intake will be permitted 1 hour after dosing). From Day 3 to Day 19 (17 days), participants will receive phenytoin 3 times daily (100mg each dose) for a total daily dose of 300 mg. On Day 16, participants will fast for at least 10 hours before the 2nd dose of ELVN-002. On dosing day (Day17), participants will take ELVN-002 360 mg orally, and then receive 100 mg of phenytoin 2 hours after dosing (allowed window: ± 5 minutes). It is okay to dose phenytoin without food. Food is not required for phenytoin dose administration. Participants will receive 100 mg of phenytoin 3 times daily after meals for a total daily dose of 300 mg. Please note for CYP3A4 inhibitor arm, it is recommended to take itraconazole with food. The Phenytoin and Itraconazole will be administered in Capsule form.

Acceptable estimated glomerular filtration rate (eGFR) for the study using the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) creatinine equation: greater than 89 mL/min/1.73 for participants 18 to 59 years old, or greater than 84 mL/min/1.73 for participants 60 years old). 7. Women of childbearing potential (WOCBP) must have a negative pregnancy test at Screening and Day -1 and be willing to have additional pregnancy tests as required throughout the study. 8.
