Eligibility
Inclusion criteria
* Participant must be 18 to 55 years of age, inclusive, at the time of signing the informed consent. * Participant must be in good general health as determined by the investigator based on medical history, physical examination, vital signs, 12-lead electrocardiogram (ECG), and clinical laboratory tests. * Participant must have body weight \> 45 kg at the Screening Visit. * Participant must have a body mass index (BMI) between 18.0 and 30.0 kg/m\^2 at the Screening Visit. BMI = body weight (kg)/(height \[m\])\^2.
Exclusion criteria
* Participant with concurrent or history of potentially fatal infections such as opportunistic infections, including sepsis and systemic fungal infection. * Participant with history of pulmonary infiltrates or pneumonia within 6 months prior to the Screening Visit. * Participant with concurrent or history of autoimmune, cardiac, hepatic, renal, gastrointestinal, respiratory, endocrine, neurological, central nervous, mental disorders, and/or hematological function disorders, which, in the judgment of the investigator, may affect participation in this clinical study. * Participant with history and/or presence of malignancy of any organ system (including basal cell carcinoma of the skin), treated or untreated.

| Changes in vital signs | From baseline to 12 weeks after the last administration | Evaluation of body temperature, blood pressure, and pulse |
| Changes in physical examinations | From baseline to 12 weeks after the last administration | Evaluation of the number and percentage of participants with normal/non-clinically significant abnormal or clinically significant abnormal results in physical examination |
| Changes in 12-lead ECGs | From baseline to 12 weeks after the last administration | Evaluation of PR, QRSd, and QT/QTcF intervals |
| Changes in laboratory parameters | From baseline to 12 weeks after the last administration | Evaluation of Hematology, Clinical chemistry, Coagulation, and Urinalysis parameters |
| Maximum observed serum concentration (Cmax) | From baseline to 12 weeks after the last administration | Evaluation of the maximum observed serum concentration of ME3241 |
| Area under the curve from time zero to the last quantifiable concentration (AUClast) | From baseline to 12 weeks after the last administration | Evaluation of the area under the curve from time zero to the last quantifiable concentration |
| Area under the curve from time zero extrapolated to infinity (AUC0-∞) | From baseline to 12 weeks after the last administration | Evaluation of the area under the curve from time zero extrapolated to infinity |
