What was measured

Grade 3/4 neutropenia was defined as at least 1 ANC value \<1.0 × 10\^9/L during the treatment period. Within each cycle, duration (days) of Grade 3/4 neutropenia was defined as the number of days from the date of the first ANC value of \<1.0 × 10\^9/L observed between start of cycle and end of cycle to the date of the first ANC value ≥1.0 × 10\^9/L that met the following criteria: 1) occurred after the ANC value of \<1.0 × 10\^9/L and 2) no other ANC values \<1.0 × 10\^9/L occurred between this day and end of cycle. The duration of Grade 3/4 neutropenia only included participants who had at least 1 Grade 3/4 neutropenia event in the cycle, and censoring rules were applied for unresolved Grade 3/4 neutropenia in a cycle. For the treatment period, the overall duration of Grade 3/4 neutropenia was the median value among the durations of Grade 3/4 neutropenia from all cycles.

Analysis population: The FAS included all randomized patients who received at least 1 dose of study drug (etoposide, carboplatin, or trilaciclib). Analyses using the FAS were conducted on the basis of the assigned treatment.
