Trilaciclib vs placebo hos patienter med småcellet lungekræft i omfattende stadie (ES-SCLC), der modtager topotecan

1. oktober 2026 opdateret af: Pharmacosmos A/S

En randomiseret, dobbeltblind, placebokontrolleret undersøgelse af Trilaciclib vs Placebo hos patienter med småcellet lungecancer i omfattende stadier (ES-SCLC), der modtager topotecan kemoterapi

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.

Detaljeret beskrivelse

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.
