Description of intervention(s) / exposure
The study is composed of 2 parts: This registration captures the information of PART A
• Part A (relative bioavailability [rBA] + food effect [FE]) will be conducted to assess the relative bioavailability, safety, and tolerability of ELVN-001 in healthy participants following a single dose of ELVN001 in capsule or tablet form. In addition, Part A will assess the food effect on a single dose of ELVN001 in tablet form in healthy participants.

Treatment Duration:
Part A: 15 Participants will be randomly assigned to receive a single dose of 80 mg ELVN-001 according to 1 of the 3 sequences at a ratio of 1:1:1 on Days 1, 8, and 15. either in fasting or fed conditions. Randomisation will be to 1 sequence only. An example of a high-fat, high-calorie meal would be two eggs fried in butter, two strips of bacon, two slices of toast with butter, four ounces of hash brown potatoes and eight ounces of whole milk.
- Sequence 1 will receive ELVN-001 in capsule and tablet form orally with 240 mL of water on Day 1 (capsule-fasted) and Day 8 (tablet-fasted), respectively. On Day 15 (tablet-fed), participants will consume a standardised (high-fat, high-calorie) breakfast within 30 minutes, and will then immediately (within 5 minutes of completion of the breakfast) receive ELVN-001 in tablet form orally with 240 mL of water. Participants will remain fasted for at least 4 hours after each dosing of ELVN-001 (water will be permitted 1 hour after dosing).
- Sequence 2 for Day 1, Day 8, and Day 15 will be tablet-fasted, tablet-fed and capsule-fasted.
- Sequence 3 will be tablet-fed, capsule-fasted, and tablet-fasted, respectively.

Participants who provide written informed consent will undergo Screening evaluations to determine eligibility within 28 days prior to Day -1. Eligible participants will be admitted to the clinical research unit (CRU) from Day -1 until the End of Confinement Visit/End of Study (EOS) or withdrawal from the study, whichever comes first. All the IP administrations will be done in the clinic under PI/delegate supervision who will monitor adherance to protocol.

Summary
Brief summary
The current study is being conducted in healthy participants to understand the appropriate drug dosage form and administration of ELVN-001. This study plans to assess the relative bioavailability of ELVN-001 in capsule and tablet forms, the safety profile of ELVN-001, and the effects of food and/or proton pump inhibitors (PPIs) on ELVN-001.

Who is it for?
Participants who provide written informed consent will undergo screening evaluations and only eligible participants will be admitted to the clinical research unit (CRU) from Day -1 until the End of Confinement Visit/End of Study (EOS) or withdrawal from the study, whichever comes first.

Study details
Participants are healthy participants between age of 18-60yrs with the BMI of more than equal to 18.5 and less than equal to 32 kg/m2 inclusive, and weigh between more than equal to 50 kg and less than equal to 100 kg, inclusive, at Screening.
The study will be conducted in with healthy participants (15 in Part A). All doses of ELVN-001 for Part A will be administered at the CRU in the presence of the PI or their designee.

Study duration
It is estimated that overall study duration to be approximately 9 months. Estimated study duration for each participant (including the screening period) is approximately 48 days.

It is hoped that this research will help determine the appropriate drug dosage form and administration of ELVN-001 and inform further clinical use of ELVN-001 in patients with CML and other therapeutic areas, such as PD.
