SECONDARY outcome
Timeframe: on Days 1, 4, 8 and 15 and beyond as applicablePopulation: Viremia subset of the Safety Analysis Population including 124 participants.
Number of participants with viremic results, including quantifiable results and results below LLOQ, by visit and by pooled trial arm. Day 29 was only tested, if Day 15 was tested positive. Viremia is measured in genome copy equivalents per milliliter (GCE/mL). All quantifiable results and results below LLOQ (\< 3214.4 GCE/mL), but above the LOD, are considered "viremic". A result of "not detected" or below LOD (\<1071,4 GCE/mL) is included as "non-viremic".
