This is a study to investigate the potential clinical benefit of trilaciclib (G1T28) in preserving the bone marrow and the immune system, and enhancing chemotherapy antitumor efficacy when administered prior to carboplatin and etoposide in first line treatment for patients with newly diagnosed extensive-stage SCLC. The study consists of 2 parts: a limited open-label, dose-finding portion (Part 1), and a randomized double-blind portion (Part 2). Both parts include 3 study phases: Screening Phase, Treatment Phase, and Survival Follow-up Phase. The Treatment Phase begins on the day of first dose with study treatment and completes at the Post-Treatment Visit. Approximately, 90 patients will be enrolled in the study; 20 patients in the Part 1 and 70 patients in the Part 2 portion.

    An AE was defined as any untoward medical occurrence in a participant administered a medicinal product that did not necessarily have a causal relationship with this treatment. TEAEs were defined as any AE that started on or after the first dose of study drug and up to the last dose +30 days. SAEs were defined as any untoward medical occurrence that at any dose resulted in death, was life threatening, required inpatient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity or was a congenital anomaly/birth defect. Relatedness to study drug was assessed by the investigator. Related refers to those events that were Possibly, Probably, or Definitely Related.

Within each cycle, 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 only included participants who had at least 1 severe neutropenia event in the cycle, and censoring rules were applied for unresolved severe neutropenia in a cycle. For the treatment period, the overall duration of severe neutropenia was the median value among the durations from all cycles.

    Cmax of trilaciclib in plasma was determined from individual concentration-time data by non-compartmental analysis methods. The actual sampling times in relation to dosing were used. For estimation of Cmax, a concentration that was below the limit of quantification (BLQ) was assigned a value of zero if it occurred in a profile before the first measurable concentration. If a BLQ value occurred after a measurable concentration in a profile, and was followed by a value above the lower limit of quantification, then the BLQ was treated as missing data. If a BLQ value occurred at the end of the collection interval (after the last quantifiable concentration) it was treated as missing data. If two BLQ values occurred in succession after Cmax, the profile was deemed to have terminated at the first BLQ value and any subsequent concentrations were omitted.
