Exclusion Criteria:

Healthy Participants:

1. The participant has received any investigational compound within 30 days prior to the first dose of study drug, or due to the half-life of the investigational drug is likely to still have detectable plasma levels of that compound.

2. The participant is an immediate family member, study site employee, or is in a dependent relationship with a study site employee who is involved in the conduct of this study (example spouse, parent, child, sibling) or may consent under duress

3. The participant has a known hypersensitivity to any component of the formulation of TAK-041.

4. The participant has a positive urine/blood drug result for drugs of abuse (defined as any illicit drug use) at Screening or Check-in (Day -1).

5. The participant taken any excluded medication, supplements, or food products during the time periods listed in the protocol.

6. The participant is lactose intolerant (Part3 only).

7. If female, the participant is of childbearing potential (example, premenopausal, not sterilized).

8. If male, the participant intends to donate sperm during the course of this study or for 145 days have elapsed since the last dose of study drug.

9. The participant has evidence of current active cardiovascular, central nervous system, hepatobiliary disease including history of biliary tree disorders, gallstones, endoscopic retrograde cholangio pancreatography (ERCP), and/or cholecystectomy, hematopoietic disease, renal dysfunction, metabolic or endocrine dysfunction, serious allergy, asthma, hypoxemia, hypertension, seizures, or allergic skin rash. There is any finding in the participant's medical history, physical examination, or safety laboratory test results (including elevated alkaline phosphatase (ALP), elevated bilirubin, elevated GGT, or elevated 5'-nucleotidase) that in the judgment of the principal investigator represents a reasonable suspicion of a disease that would contraindicate taking TAK-041, or that might interfere with the conduct of the study. This includes, but is not limited to, peptic ulcer disease, cholestasis, seizure disorders, and cardiac arrhythmias.

10. The participant has current or recent (within 6 months) gastrointestinal disease that would be expected to influence the absorption of drugs (that is, a history of malabsorption, esophageal reflux, peptic ulcer disease, erosive esophagitis, frequent [more than once per week] occurrence of heartburn, or any surgical intervention).

11. Had major surgery, or donated or lost 1 unit of blood (approximately 500 mL) within 4 weeks prior to Screening.

12. The participant has a history of cancer, except basal cell carcinoma that has been in remission for at least 5 years prior to Day 1. Participant has a positive test result for hepatitis B surface antigen (HBsAg), hepatitis C virus (HCV) antibody at Screening or a known history of human immunodeficiency virus (HIV) infection.

13. The participant has used nicotine-containing products (including but not limited to cigarettes, pipes, cigars, chewing tobacco, nicotine patch or nicotine gum) within 21 days prior to Check-in on Day -1. Cotinine test is positive at Screening or Day -1.

14. The participant has poor peripheral venous access.

15. Had a transfusion of any blood product within 30 days prior to Day 1.

16. Participant has a Screening or Check-in abnormal (clinically significant) electrocardiogram (ECG). Entry of any participant with an abnormal (not clinically significant) ECG must be approved, and documented by signature of the principal investigator or a medically qualified sub-investigator.

18. The participant has a QT interval with Fridericia correction method (QTcF) >450 millisecond (ms) or PR outside the range 120 to 220 ms, confirmed on repeat testing within a maximum of 30 minutes, at the Screening Visit or Check-in.

19. The participant has abnormal Screening or Check-in laboratory values (> upper limit of normal [ULN] for the respective serum chemistries) of alanine transaminase (ALT), aspartate aminotransferase (AST), total bilirubin (TBILI), ALP, gamma-glutamyl transpeptidase (GGT), 5'nucleotidase (Screening only) and/or abnormal urine osmolality, confirmed upon repeat testing.

20. The participant has a clinically significant history of head injury or trauma associated with loss of consciousness for >15 minutes.

21. Is considered by the investigator to be at an imminent risk of suicide injury to self, other, property, or participants who within the past year prior to Screening have attempted suicide. Participants having positive answer on item 4 or 5 on Columbia Suicide Severity Rating Scale (C-SSRS) (based on the past year) prior to randomization are excluded.

22. The participant has a history of significant skin reactions (hypersensitivity) to adhesives, metals or plastic; this criterion applies only to participants participating in the study of the two wearable digital devices.

Participants with schizophrenia only:

1. Has an undetectable level of baseline antipsychotic medication at Screening.

2. Has a lifetime diagnosis of schizoaffective disorder; a lifetime diagnosis of bipolar disorder; or a lifetime diagnosis of obsessive compulsive disorder based on the Mini International Neuropsychiatric Interview (MINI) combined with the general psychiatric evaluation. As an exception, participants with a historical prior lifetime diagnosis of schizoaffective disorder may be enrolled in the study with sponsor or designee approval provided that the principal investigator can attest that the participant's overall history and current clinical presentation and history is most consistent with schizophrenia, not schizoaffective disorder.

3. Has a recent (within the last 6 months) diagnosis of panic disorder, depressive episode, or other comorbid psychiatric conditions requiring clinical attention based on the MINI for DSM-5 and the general psychiatric evaluation.

4. Has a history of drug abuse (defined as any illicit drug use) or a history of alcohol abuse (defined as 4 or more alcoholic beverages per day) within 1 year prior to the Screening Visit or is unwilling to agree to abstain from alcohol and drugs throughout the study.

5. Has a diagnosis of substance use disorder (with the exception of nicotine dependence) within the preceding 6 months based on the MINI for DSM-5 and the general psychiatric evaluation.

6. Has evidence or history of current clinically significant cardiovascular disease, including uncontrolled hypertension (standing or supine diastolic blood pressure >90 millimeter of mercury (mm Hg) and/or standing or supine systolic blood pressure >145 mm Hg, with or without treatment), symptomatic ischemic heart disease, uncompensated heart failure or recent (past 12 months) acute myocardial infarction or bypass surgery. Controlled essential hypertension, non-clinically significant sinus bradycardia and sinus tachycardia will not be considered significant medical illnesses and would not exclude a participant from the study. Other well-controlled medical illnesses may be permitted that do not increase hepatic risks or other safety risks to the participant's participation in the judgement of the investigator in consultation with the sponsor or designee.

7. Has evidence of clinically significant extrapyramidal symptoms as measured by a Simson-Angus Scale (SAS) score >6.

8. The participant has evidence of depression as measured by a Calgary Depression Score (CDSS) score >9.

9. Has received TAK-041 in a previous clinical study; or has previously or is currently participating in this study; has received treatment with other experimental therapies within the preceding 60 days or <5 half-lives prior to randomization, whichever is longer; has participated in 2 or more clinical studies within 12 months prior to Screening; or has participated in a clinical study for a psychiatric condition that is exclusionary per this protocol.
