E.3 | Principal inclusion criteria |
Subject eligibility is determined according to the following criteria before entry into the study:

2. Subject is capable of understanding and complying with protocol requirements.
3. Male subject who is not sterilized and sexually active with a female partner of childbearing potential, must use barrier contraception from signing of informed consent until 5 half-lives of TAK-994 plus 90 days after the last
dose of study drug. In addition, they must be advised not to donate sperm during this period.
4. Female subject of childbearing potential who is sexually active with a male partner who is not sterilized, must agree to use highly effective methods of contraception from signing of informed consent until 5 half-lives of TAK-994 plus 30 days after the last dose of study drug. In addition, they must be advised not to donate ova during this period.

8. The subject’s renal creatinine clearance is ≤50 mL/min.
9. Has liver function tests (alanine aminotransferase, aspartate aminotransferase) higher than 1.5 times the upper limit of normal at any visit in TAK-994-1501.
10. The subject has a risk of suicide according to endorsement of Item 4 or 5 on the Columbia Suicide Severity Rating
Scale (C-SSRS) at any visit during TAK-994-1501 and/or has made a suicide attempt during TAK-994-1501. |
