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

  Physical examination will be assessed.

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

• Number of participants with change in 12-lead ECG readings

  12-lead ECG will be assessed.

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

  At specified timepoints pre-dose and up to 169 days post first dose administration

• PK parameters- Time for maximum observed Concentration (Tmax)

  At specified timepoints pre-dose and up to 169 days post first dose administration

• PK parameters- Area under the curve (AUC)

  At specified timepoints pre-dose and up to 169 days post first dose administration

• PK parameters- Volume of distribution (Vz)

  At specified timepoints pre-dose and up to 169 days post first dose administration

• PK parameters- Total clearance (CL)

  At specified timepoints pre-dose and up to 169 days post first dose administration
