Trilaciclib, a CDK 4/6 Inhibitor, in Patients Receiving Docetaxel for Metastatic Non-Small Cell Lung Cancer (NSCLC) (PRESERVE 4)
Study Details
Study Description
Brief Summary
This is a randomized, double-blind, placebo-controlled, global, multicenter, Phase 2 trial evaluating the effect of trilaciclib on overall survival when administered prior to docetaxel in patients with mNSCLC treated in the 2nd or 3rd line setting.
Condition or Disease | Intervention/Treatment | Phase |
---|---|---|
|
Phase 2 |
Detailed Description
Patients must have documented disease progression during or after one or two lines of systemic therapy for recurrent or metastatic NSCLC. Prior treatment must have included, either in the same line or as separate lines of therapy: 1) a maximum of 1 line of platinum-containing chemotherapy for recurrent/metastatic disease and 2) a maximum of 1 line of a locally approved/authorized programmed cell death protein 1 (PD-1)/programmed death-ligand 1 (PD-L1) monoclonal antibody (mAb) containing regimen for recurrent/metastatic disease.
Patients will be randomly assigned (1:1) to receive trilaciclib or placebo intravenously (IV) prior to docetaxel on Day 1 of each 21-day cycle.
The study will include a screening phase, a treatment phase and a survival follow-up phase. The patient may continue to receive treatment on study until disease progression, unacceptable toxicity, withdrawal of consent, discontinuation by Investigator, or the end of the trial, whichever occurs first.

Outcome Measures
Primary Outcome Measures
- Effect of trilaciclib on Overall Survival (OS) compared with placebo [From the date of randomization to the date of death for patients who died in the study due to any cause, or to the last contact date known to be alive for those who survived as of the data cutoff date, assessed up to 30 months.]

Secondary Outcome Measures
- Effect of trilaciclib on Progression Free Survival (PFS) compared with placebo [From date of randomization to the date of documented radiologic PD per RECIST v1.1 or date of death regardless of the cause, whichever comes first, for those who had the events. Otherwise, PFS is calculated per censoring rules, assessed up to 30 months.]

- Effect of trilaciclib on the neutrophil lineage compared with placebo [From randomization to the end of the last study treatment cycle (each cycle is 21 days), assessed up to 19 months.]
To assess the effects of trilaciclib administered prior to docetaxel compared with placebo administered prior to docetaxel on duration of severe (grade 4) neutropenia in cycle 1, occurrence of severe (grade 4) neutropenia, occurrence of febrile neutropenia AEs, and occurrence of granulocyte colony-stimulating factor (G-CSF) administration in patients with metastatic NSCLC receiving docetaxel in the second or third line.
- Effect of trilaciclib on the red blood cell (RBC) lineage compared with placebo [From randomization to the end of the last study treatment cycle (each cycle is 21 days), assessed up to 19 months.]
To assess the effects of trilaciclib administered prior to docetaxel compared with placebo administered prior to docetaxel on occurrence of grade 3 or 4 decreased hemoglobin laboratory values, red blood cell (RBC) transfusions on or after week 5 (occurrence and number of transfusions), occurrence of erythropoiesis stimulating agent (ESA) administration in patients with metastatic NSCLC receiving docetaxel in the second or third line.
- Effect of trilaciclib on the platelet lineage compared with placebo [From randomization to the end of the last study treatment cycle (each cycle is 21 days), assessed up to 19 months.]
To assess the effects of trilaciclib administered prior to docetaxel compared with placebo administered prior to docetaxel on occurrence of grade 3 or 4 decreased platelet count laboratory values and platelet transfusions (occurrence and number of transfusions) in patients with metastatic NSCLC receiving docetaxel in the second or third line.
- Effect of trilaciclib on chemotherapy dosing compared with placebo [From randomization to the end of the last study treatment cycle (each cycle is 21 days), assessed up to 19 months.]
