Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 30 participants
Allocation: Randomized

  4. Time to normalization of temperature (≤100.4ºF [38.0ºC]) [ Time Frame: Baseline through Day 14 or discharge ]
  5. Change from baseline in World Health Organization (WHO) Ordinal Scale score on Days 5, 7, 14, 28, and 60 [ Time Frame: Baseline through Day 60 ]
