A Research Study of the Effect of Etavopivat on Other Drugs in Healthy Participants

An Open-Label, Fixed-Sequence Study to Evaluate the Effect of Etavopivat on the Single-Dose Pharmacokinetics of Midazolam, Digoxin, Rosuvastatin, Pitavastatin, and Metformin in Healthy Adult Participants

The study aims to test if a new medicine called etavopivat potentially affects other medicines in healthy participants. The purpose of the study is to investigate whether the use of etavopivat affects the breakdown and metabolism of commonly used medicines in the body. During the study, participants will receive etavopivat and five different medicines that are already approved and available on the market, and which can be prescribed by doctors. These marketed medicines are called substrate drugs and they are: digoxin, pitavastatin, metformin, midazolam, and rosuvastatin. During a period of the study, participants will take 2 tablets of etavopivat daily for 10 consecutive days. The study will last for about 34 to 64 days.

Inclusion Criteria:

• Body mass index (BMI) between 18.5 and 29.9 kilograms per square meter (kg/m^2) (both inclusive) at screening.
• Body weight greater than (>) 50.0 kg at screening.
