From date of first dose of study drug (Part 1)/randomization (Part 2) until the date of death due to any cause (evaluated up to a maximum of 2220 days).

What was measured

Median time (months) and 95% CI from date of first dose date of study drug/randomization until date of death. Patients who do not die during the study will be censored at the date last known to be alive.

Analysis population: The intent-to-treat (ITT) analysis set: All enrolled patients who received at least one dose of study drugs in Part 1 and all randomized patients in Part 2 on the basis of the assigned treatment.

Groups in this outcome

Placebo + Topotecan 1.5 mg/m² - Parts 2a and 2b

Patients in Parts 2a and 2b were randomized 1:2 to placebo. Patients received placebo administered IV once daily on Days 1 to 5 of each 21-day topotecan chemotherapy cycle. Following administration of placebo on Days 1 to 5, patients received IV topotecan (1.5 mg/m²). Placebos Topotecan

Trilaciclib (G1T28) 240 mg/m² + Topotecan 0.75 mg/m² - Part 2a

Patients in Part 2a were randomized 2:1 to trilaciclib. Patients received trilaciclib (240 mg/m²) administered IV once daily on Days 1 to 5 of each 21-day topotecan chemotherapy cycle. Following administration of trilaciclib on Days 1 to 5, patients received IV topotecan (0.75 mg/m²). Trilaciclib Topotecan

Patients received trilaciclib (280 mg/m²) administered intravenously (IV) once daily on Days 1 to 5 of each 21-day topotecan chemotherapy cycle. Following administration of trilaciclib on Days 1 to 5, patients received IV topotecan (0.75 mg/m²).

Trilaciclib (G1T28) 240 mg/m² + Topotecan 1.0 mg/m² - Cohort 7- Part 1

Patients received trilaciclib (240 mg/m²) administered intravenously (IV) once daily on Days 1 to 5 of each 21-day topotecan chemotherapy cycle. Following administration of trilaciclib on Days 1 to 5, patients received IV topotecan (1.0 mg/m²).
