About

This is a multicenter，randomized, open label, active-controlled, parallel-group study comparing efficacy and safety of LY01610(Irinotecan hydrochloride liposome Injection) and Topotecan in Patients with Recurrent Small Cell Lung Cancer (SCLC)

Full description

A multicenter, randomized, open-label, parallel study was designed to evaluate the efficacy and safety of LY01610 versus topotecan in the second-line treatment of patients with recurrent SCLC who were diagnosed by histopathology and/or cytology and had disease progression after first-line platinum-based chemotherapy, to conduct a population pharmacokinetics (PopPk) study, and to explore the effect of genetic polymorphisms on the pharmacokinetics properties, efficacy and safety of this product.

Enrollment: 686 estimated patients

Volunteers: Accepts Healthy Volunteers

8. Patients with brain metastasis at baseline should meet all the following conditions: lesions not involving the brainstem, the number of brain metastases ≤ 2 (but patients with only intracranial target lesions should be excluded), imaging stability for at least 3 weeks after local treatment control, and no application of dehydration drugs and hormones before screening,Without any symptoms of brain metastasis;
