Study Details

Study Description

Brief Summary

This is a Phase 3, multicenter, randomized, double-blind, placebo-controlled study evaluating the safety and efficacy of trilaciclib versus placebo administered prior to gemcitabine and carboplatin in patients receiving first- or second-line treatment for locally advanced unresectable/metastatic TNBC.

Condition or Disease Intervention/Treatment Phase
Phase 3

Detailed Description

This study will have two separate cohorts (Cohort 1 and Cohort 2). Both cohorts will follow the same general study conduct/design with similar primary and key secondary endpoints and identical treatment arms.

  • Cohort 1 will evaluate patients receiving first-line therapy, regardless of programmed death-ligand 1 (PD-L1) status, who are programmed cell death protein 1 (PD-1)/PD-L1 inhibitor therapy naïve.

  • Cohort 2 will evaluate PD-L1 positive patients receiving second-line therapy following prior PD-1/PD-L1 inhibitor therapy in the locally advanced unresectable/metastatic setting.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Trilaciclib + gemcitabine + carboplatin

Trilaciclib (240mg/m2) + gemcitabine (1000 mg/m2) and carboplatin (AUC 2)

Drug: Trilaciclib
Trilaciclib administered IV over 30mins prior to chemotherapy on Day 1 and Day 8 of each 21-day cycle.
Other Names:
  • G1T28
  • COSELA
  • Drug: Gemcitabine
    Gemcitabine administered IV on Day 1 and Day 8 of each 21-day cycle.

    Drug: Carboplatin
    Carboplatin administered IV on Day 1 and Day 8 of each 21-day cycle.

    Placebo Comparator: Placebo + gemcitabine + carboplatin

    The subjects in the placebo arm will follow the same schedule as the trilaciclib arm, but will receive placebo instead of trilaciclib.

    Drug: Placebo
    Placebo administered IV over 30mins prior to chemotherapy on Day 1 and Day 8 of each 21-day cycle.
    Other Names:
  • 0.9% normal saline
  • 5 % Dextrose in water (D5W)
  • Drug: Gemcitabine
    Gemcitabine administered IV on Day 1 and Day 8 of each 21-day cycle.

    Drug: Carboplatin
    Carboplatin administered IV on Day 1 and Day 8 of each 21-day cycle.

    Outcome Measures

    Primary Outcome Measures

    1. Effect on Overall Survival (OS) [Cohort 1:From date of randomization up to 39 months]

      (Cohort 1):To evaluate the effect of trilaciclib on overall survival (OS) compared with placebo in patients receiving first-line gemcitabine and carboplatin.

    2. Effect on Overall Survival (OS) [Cohort 2: From date of randomization up to 28 months]

      (Cohort 2): To evaluate the effect of trilaciclib on OS compared with placebo in patients receiving gemcitabine and carboplatin as second-line therapy after treatment with a PD-1/PD-L1 inhibitor in the locally advanced unresectable/metastatic setting

    Secondary Outcome Measures

    1. Quality of life/Effects On Chemotherapy-Induced Fatigue [Cycle 1 Day 1 (each cycle is 21 days) up to 14 months]

      To assess the effect of trilaciclib on patients' quality of life as measured by time to first confirmed deterioration of fatigue compared with placebo in patients receiving gemcitabine and carboplatin

    2. Myeloprotective Effects [Cycle 1 Day 1 (each cycle is 21 days) up to 14 months]

      Occurrence of cytopenias, febrile neutropenia, hospitalization due to chemotherapy-induced myelosuppression, RBC and platelet transfusions, growth factor administration, and dose reductions and delays

    3. Progression Free Survival [From date of randomization up to 14 months)]

      To evaluate the effect of trilaciclib on progression-free survival (PFS) compared with placebo in patients receiving gemcitabine and carboplatin.
