Myeloprotection With Trilaciclib in Pan-cancer Population

Official title

Efficacy and Safety of Trilaciclib in Myeloprotection During Chemotherapy for Advanced/Recurrent Malignant Solid Tumors - A Phase II Study

Overview

The goal of this open-label randomized controlled study is to assess the myeloprotective effect of trilaciclib in pan-cancer population. The main questions it aims to answer are: * effect and safety of trilaciclib on myeloprotection in cancer patients receiving paclitaxel plus carboplatin chemotherapy * does trilaciclib 's myeloprotective efficacy in patients receiving the same chemotherapy regimen correlate with tumor type Participants will be randomized 2:1 to the treatment arm of trilaciclib in combination with a paclitaxel and carboplatin-based regimen and the control arm of a paclitaxel and carboplatin-based regimen for at least 6 cycles or until disease progression or intolerable toxicity. Patients in both groups could extend the chemotherapy cycle at the investigator 's discretion depending on the tumor type and in combination with anti-angiogenic/PD-X/anti-HER2 therapy.

• Requires concurrent radiotherapy;
• Known history of hypersensitivity to the drug components of this protocol;
• Pregnant or lactating women;
• Any other condition that, in the opinion of the investigator, would make the patient inappropriate for participation in this study.
