Description of intervention(s) / exposure
Treatment: Drugs - Trilaciclib
Treatment: Drugs - Placebo
Treatment: Drugs - Gemcitabine

Treatment: Drugs: Placebo
Placebo administered IV over 30mins prior to chemotherapy on Day 1 and Day 8 of each 21-day cycle.

Treatment: Drugs: Gemcitabine
Gemcitabine administered IV on Day 1 and Day 8 of each 21-day cycle.

Treatment: Drugs: Carboplatin
