PRESERVE 2: Trilaciclib, a CDK 4/6 Inhibitor, in Patients Receiving Gemcitabine and Carboplatin for Metastatic Triple-Negative Breast Cancer (TNBC)
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.

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.
Study Design
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:
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:
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
- 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.
- 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
- 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
- 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
- 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.
