- Induction Period. From date of randomization, 21 day treatment cycles up to a maximum of 4 cycles or until (if earlier) disease progression, unacceptable toxicity, or discontinuation by the patient or investigator, assessed up to a maximum of 409 days.
What was measured
The occurrence of severe (Grade 4) neutropenia (SN) was a binary variable. If a patient had at least 1 absolute neutrophil count value \<0.5 × 10\^9/L during the Induction Period, the patient was assigned as Yes to the occurrence of SN; otherwise, it was No.
Analysis population: Intent-to-treat (ITT) analysis set included all randomized patients. Analysis using the ITT analysis set were conducted on the basis of the randomly assigned treatment.
Groups in this outcome
Trilaciclib+Etoposide/Carboplatin/Atezolizumab
Induction: Patients received trilaciclib 240 mg/m² administered IV once daily prior to E/P/A on Days 1, 2 and 3 of each 21-day E/P/A therapy cycle (up to 4 cycles in total). Etoposide 100 mg/m² was administered IV daily on Days 1, 2, and 3 of each 21-day cycle. Carboplatin was administered on Day 1 of each 21-day cycle using the Calvert formula with a target AUC = 5 mg/mL/min to calculate the dose. Atezolizumab 1200 mg was administered as an IV infusion on Day 1 of each 21-day cycle. Maintenance: Following the induction phase, patients received maintenance atezolizumab at a dose of 1200 mg on Day 1 of every 21-day cycle until disease progression, unacceptable toxicity, or discontinuation by the patient or investigator
Placebo+Etoposide/Carboplatin/Atezolizumab
Induction: Patients received placebo administered IV once daily prior to E/P/A on Days 1, 2 and 3 of each 21-day E/P/A therapy cycle (up to 4 cycles in total). Etoposide 100 mg/m² was be administered IV daily on Days 1, 2, and 3 of each 21-day cycle. Carboplatin was administered on Day 1 of each 21-day cycle using the Calvert formula with a target AUC = 5 mg/mL/min to calculate the dose. Atezolizumab 1200 mg was administered as an IV infusion on Day 1 of each 21-day cycle. Maintenance: Following the induction phase, patients received maintenance atezolizumab at a dose of 1200 mg on Day 1 of every 21-day cycle until disease progression, unacceptable toxicity, or discontinuation by the patient or investigator.

Source statistical analyses
- group Description
- The occurrence of SN was a binary variable. Treatment group difference was analyzed using a modified Poisson regression model to account for the variable duration of the Induction Period for each patient. The model included baseline ANC count as a covariate, the stratification factors of ECOG performance status (0 to1 vs. 2) and brain metastases (Yes vs. No), and treatment as a fixed effect. The logarithm transformation of # of Induction cycles was included as an offset variable in the modeling.

- A Hochberg-based gatekeeping procedure was used to control the global familywise error rate across the multiple null hypotheses (for 2 primary and 3 key secondary endpoints) in a strong sense at a 1-sided 0.025 level.
