What was measured

In addition to deriving severe (Grade 4) neutropenia using the method described for the primary endpoints, an approach was applied that accounted for participants who did not experience a severe neutropenia event in Cycle 1. For the post-hoc analysis, severe neutropenia was defined as at least 1 ANC value \<0.5 × 10\^9/L during the treatment period. In Cycle 1, the duration (days) of severe neutropenia was defined as the number of days from the date of the first ANC value of \<0.5 × 10\^9/L observed between start of cycle and end of cycle to the date of the first ANC value ≥0.5 × 10\^9/L that met the following criteria: 1) occurred after the ANC value of \<0.5 × 10\^9/L and 2) no other ANC values \<0.5 × 10\^9/L occurred between this day and end of cycle. The duration of severe neutropenia was set to 0 for participants who did not experience severe neutropenia in Cycle 1. Data from unscheduled visits and the actual assessment date (rather than visit date) were included in the derivation.

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.
