Plain-language summary
This was a randomized, double-blind, placebo-controlled, global, multicenter, Phase 3 trial evaluating the impact of trilaciclib on myelopreservation and anti-tumor efficacy when administered prior to FOLFOXIRI/bevacizumab in patients with pMMR/MSS mCRC who have not received systemic therapy for metastatic disease.

Inclusion criteria
. Age ≥ 18 years of age at the time of signing the informed consent. Patients \> 70 years of age must have a G8 Health State Screening Tool (geriatric screening tool) score \> 14.
. Proficient mismatch repair/microsatellite stable (pMMR/MSS), histologically or cytologically-confirmed adenocarcinoma of the colon or rectum. Patients with any BRAF or KRAS mutation status (wild type or mutant) are eligible. If historical pMMR/MSS and/or BRAF V600E mutational status are not known, a tumor specimen (archival or fresh biopsy) must be sent for testing and results must be available at the time of randomization in interactive web response system (IWRS). If testing cannot be completed using a standard clinical assay performed institutionally/locally, the tumor specimen may be sent to the Sponsor's designated central laboratory for analysis; only historical KRAS mutational status will be collected (ie, no testing required prior to study entry). Note: Any sample sent for MSS/BRAF analysis will be in addition to that required per Inclusion Criterion 5.
. Unresectable and measurable or metastatic colorectal cancer per RECIST v1.1
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Duration of Severe Neutropenia (DSN)
Timeframe: Cycles 1 to 4 (14-day cycles up to 56 days)
2
Occurrence of Severe Neutropenia (SN) During Induction
Timeframe: Induction Period, cycles 1-12 (14-day cycles up to 168 days)
. A formalin-fixed paraffin-embedded (FFPE) tumor specimen (from archival or fresh biopsy) with an associated pathology report documenting pMMR/MSS mCRC must be confirmed to be available to send to the Sponsor for planned retrospective biomarker analyses (tissue requirements are provided in the associated laboratory manual).
. Hemoglobin ≥ 9.0 g/dL in the absence of RBC transfusion or ESA administration within 14 days prior to first dose of trilaciclib/placebo
. Prior systemic therapy for mCRC. Patients who received adjuvant/neoadjuvant therapy (ie, treatment with curative intent) for colorectal cancer are eligible if it has been ≥ 6 months between the last dose of systemic chemotherapy and the date of informed consent.
. Any radiotherapy, chemotherapy, immunotherapy, biologic, investigational, or hormonal therapy for cancer treatment (except for adjuvant hormonal therapy for breast cancer or prostate cancer defined as M0 disease or PSA persistence/recurrence without metastatic disease) within 3 weeks prior to the first dose of trilaciclib/placebo.
. Receipt of any low-dose systemic chemotherapeutic agent (e.g., low-dose methotrexate for rheumatoid arthritis) administered for a nononcologic purpose within 3 weeks prior to the first dose of trilaciclib/placebo.
. Presence of central nervous system (CNS) metastases/leptomeningeal disease requiring immediate treatment with radiation therapy or steroids (i.e., patient must be off steroids administered for brain metastases for at least 14 days prior to the first dose of trilaciclib/placebo).
. QTcF interval \> 450 msec (males) or \> 470 msec (females) at screening. For patients with ventricular pacemakers, QTcF \> 500 msec.
