Primary outcomes

  1. Number of Participants With SAEs

    Time frame: From first dose of study drug up to 24 weeks

    A SAE is defined as any untoward medical occurrence: resulting in death; life threatening requiring hospitalization or prolongation of hospitalization; resulting in persistent or significant disability or incapacity; resulting in birth defect or congenital anomaly or medically important due to other reasons than above mentioned criteria.

  2. Number of Participants With ADRs

    Time frame: From first dose of study drug up to 24 weeks

    An ADR is defined as harmful and unintended responses to the normal administration/use of drugs, in which a causal relationship with the drug in question cannot be ruled out. AEs with unknown causality to the drug among those voluntarily reported will be also considered ADRs.

  3. Number of Participants With Unexpected AEs

    Time frame: From first dose of study drug up to 24 weeks

    An AE is defined as any untoward and unintended signs (example, anomalies in laboratory test results) or symptoms/diseases occurring during administration/use of drugs, which do not necessarily have a causal relationship with the drug in question. An unexpected AE is an AE with a difference in nature, severity, specificity, or outcome, compared to the product licensure/safety notification of the drug.

  4. Number of Participants With Unexpected ADRs

    Time frame: From first dose of study drug up to 24 weeks

    An ADR is defined as harmful and unintended responses to the normal administration/use of drugs, in which a causal relationship with the drug in question cannot be ruled out. AEs with unknown causality to the drug among those voluntarily reported will be also considered ADRs. An unexpected ADR is an ADR with difference in the nature or severity, specificity, or the outcome, compared to the product licensure/notification of the drug.

  5. Number of Participants With Known ADRs

    Time frame: From first dose of study drug up to 24 weeks

    An ADR is defined as harmful and unintended responses to the normal administration/use of drugs, in which a causal relationship with the drug in question cannot be ruled out. AEs with unknown causality to the drug among those voluntarily reported will be also considered ADRs. Known ADRs are those listed in product licensure/notification of the drug.

  6. Number of Participants With Non-serious ADRs

    Time frame: From first dose of study drug up to 24 weeks

    An ADR is defined as harmful and unintended responses to the normal administration/use of drugs, in which a causal relationship with the drug in question cannot be ruled out. AEs with unknown causality to the drug among those voluntarily reported will be also considered ADRs.

Secondary outcomes

  1. Change From Baseline in Score of Clinical Global Impression of Change (CGIC)

    Time frame: Baseline up to 24 weeks

    The CGIC is a 7-point scale that measures a physician's global impression of a participant's clinical condition. Scale ranges from 1 to 7 with lower scores indicating improvement (1=very much improved, 2=much improved, 3=minimally improved), higher scores indicating worsening (5=minimally worse, 6= much worse, 7=very much worse), and a score of 4 indicating no change.
