トポテカン投与中の進展期小細胞肺がん(ES-SCLC)患者におけるトリラシクリブとプラセボの比較

2026年10月1日 更新者:Pharmacosmos A/S

トポテカン化学療法を受けている進行期小細胞肺がん(ES-SCLC)患者を対象とした、トリラシクリブとプラセボの無作為化二重盲検プラセボ対照試験

This is a multicenter, randomized, double-blind, placebo-controlled study to assess whether trilaciclib administered prior to topotecan is non-inferior to placebo administered prior to topotecan with regard to overall survival.

詳細な説明

The study will include 3 study phases: Screening Phase, Treatment Phase, and Survival Follow-up Phase. Patients randomized in this study will receive trilaciclib/placebo + topotecan 1.5 mg/m2 until disease progression, unacceptable toxicity, withdrawal of consent, Investigator decision to discontinue treatment, or the end of the trial, whichever comes first.

Trilaciclib was approved by the United States (US) Food and Drug Administration (FDA) as a treatment 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 ES-SCLC. As a post-marketing requirement, the FDA asked the Sponsor to conduct a study in patients with ES-SCLC undergoing chemotherapy to evaluate survival and disease progression following trilaciclib administration in patients treated with a platinum/etoposide-containing regimen or topotecan-containing regimen with at least 2 years of follow-up. This study is designed to fulfill this requirement.

実験的:Trilaciclib (G1T28) 240 mg/m² + Topotecan 1.5 mg/m²

Patients randomized 1:1 to trilaciclib. Patients receive trilaciclib (240 mg/m²) administered once daily on Days 1 to 5 of each 21-day topotecan chemotherapy cycle.

Following administration of trilaciclib on Days 1 to 5, patients receive topotecan (1.5 mg/m²)

Participants will receive intravenous trilaciclib infusion
