Trilaciclib vs. Placebo bei Patienten mit kleinzelligem Lungenkrebs im fortgeschrittenen Stadium (ES-SCLC), die Topotecan erhalten

1. Oktober 2026 aktualisiert von: Pharmacosmos A/S

Eine randomisierte, doppelblinde, placebokontrollierte Studie zu Trilaciclib im Vergleich zu Placebo bei Patienten mit kleinzelligem Lungenkrebs im Extensivstadium (ES-SCLC), die eine Topotecan-Chemotherapie erhalten

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.

Detaillierte Beschreibung

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.

Intervention / Behandlung
Experimental: 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

Placebo-Komparator: Placebo + Topotecan 1.5 mg/m²

Patients are randomized 1:1 to placebo. Patients receive placebo administered once daily on Days 1 to 5 of each 21-day topotecan chemotherapy cycle.

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

Participants will receive intravenous topotecan infusion
