    Time frame: Part A- Up to Day 141; Part B - Up to Day 169 post first dose administration

  2. Number of participants with change in Laboratory assessments

    Laboratory assessments include hematology, coagulation, clinical chemistry and urinalysis

    Time frame: Part A- Up to Day 141; Part B - Up to Day 169 post first dose administration

  3. Number of participants with change in vital sign measurements following dose administration.

    Blood pressure and heart rate will be assessed.

    Time frame: Part A- Up to Day 141; Part B - Up to Day 169 post first dose administration

  4. Number of participants with change in physical examination following dose administration.

    Physical examination will be assessed.

    Time frame: Part A- Up to Day 141; Part B - Up to Day 169 post first dose administration

  5. Number of participants with change in 12-lead ECG readings

    12-lead ECG will be assessed.

    Time frame: Part A- Up to Day 141; Part B - Up to Day 169 post first dose administration
