At a glance

Trilaciclib is indicated to decrease the incidence of chemotherapy-induced myelosuppression in adult patients when administered prior to a platinum/etoposide-containing regimen or topotecan-containing regimen for extensive-stage small cell lung cancer (ES-SCLC).

Description

Trilaciclib is a transient inhibitor of CDK 4 and 6. Hematopoietic stem and progenitor cells (HSPCs) in the bone marrow give rise to circulating neutrophils, RBCs, and platelets. HSPC proliferation is dependent on CDK4/6 activity.

Indications
  • Decrease incidence of chemotherapy-induced myelosuppression (ES-SCLC)
Therapeutic class

Transient inhibitor

Pharmacological class

CDK 4/6 Inhibitor

Pharmacology

Trilaciclib is a transient inhibitor of CDK 4 and 6. HSPC proliferation is dependent on CDK4/6 activity. Trilaciclib causes transient G1 arrest of hematopoietic stem cells, contributing to its myeloprotective effect.

Mechanism of action

Inhibits CDK4/6, causing transient G1 arrest of HSPCs, providing myeloprotection.

Dosage

Adult Dose (IV):

  • 240 mg/m² per dose as a 30-minute IV infusion completed within 4 hours prior to chemotherapy
  • Interval between doses on sequential days should not be greater than 28 hours
