An adverse event (AE) is any untoward medical occurrence in a clinical investigation participant administered a pharmaceutical product. A TEAE is defined as any event emerging or manifesting at or after the initiation of treatment with a study intervention or medicinal product or any existing event that worsens in either intensity or frequency following exposure to the study intervention or medicinal product.

Parts A, B and C: Number of Participants With at Least One Treatment-emergent Adverse Events (TEAEs)
Up to approximately 28 weeks

An adverse event (AE) is any untoward medical occurrence in a clinical trial participant, temporally associated with the use of the trial intervention, whether or not the occurrence is considered related to the trial intervention. A TEAE is defined as any event emerging or manifesting at or after the initiation of treatment with a study intervention or medicinal product or any existing event that worsens in either intensity or frequency following exposure to the study intervention or medicinal product.

Number of Participants With at Least One Treatment-emergent Adverse Event (TEAE)

TAK-360 Long Term Extension (LTE) PhaseEXPERIMENTALParticipants will receive one of the available TAK-360 doses for up to approximately 5 years in this trial. Participants will enter the LTE on the dose they were in the parent trial or for participants with discontinued dosing regimen in the parent trial to the next closest available dose/dosing regimen for their indication in this trial. Participants rolling over to this trial from a placebo arm in the parent trial, will receive one of the available TAK-360 doses. Placebo will be only administered as needed to maintain dose blinding between TAK-360 doses and regimens.
