A Study to Compare Trilaciclib versus Placebo in Patients Receiving FOLFOXIRI/Bevacizumab for Metastatic Colorectal Cancer


About this study

This study aims to evaluate 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.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.

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 are eligible.
  • Unresectable and measurable or evaluable disease per RECIST v1.1.
  • ECOG performance status of 0 to 1.
  • 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.
  • Adequate organ function.

Exclusion Criteria:

  • 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.
  • QTcF interval > 450 msec (males) or > 470 msec (females) at screening. For patients with ventricular pacemakers, QTcF > 500 msec.
  • Personal or family history of long QT syndrome.
  • Symptomatic peripheral neuropathy.
  • History of interstitial lung disease (ILD).
  • Prior allogeneic or autologous hematopoietic stem cell or bone marrow transplantation.
