Trilaciclib, a CDK 4/6 Inhibitor, in Patients Receiving Docetaxel for Metastatic Non-Small Cell Lung Cancer (NSCLC) (PRESERVE 4)

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. This study was terminated by the Sponsor for non-safety reasons. At the time of study termination, 10 patients had been screened, 7 were randomized, and 2 of the 7 had discontinued from the study. In addition, it was decided that there would be no statistical analyses of the efficacy or safety data due to the limited number of patients treated (N=7).
