Официальное название

A Multicenter, Randomized, Open-Label Phase II/III Clinical Study on the Efficacy and Safety of LB1410 Plus Lenvatinib With or Without LB4330 Versus Investigator's Choice of Chemotherapy in Advanced Recurrent/Metastatic Cervical Cancer

Обзор

This is a multicenter, randomized, open-label Phase II/III clinical study, aiming to evaluate the efficacy and safety of LB1410 in combination with lenvatinib (whether in combination with LB4330）versus the chemotherapy regimen selected by the investigators for patients with advanced recurrent/metastatic cervical cancer.

Подробное описание

This study is an open-label, multicenter Phase II/III clinical trial in advanced/metastatic cervical cancer to evaluate the antitumor efficacy, safety, tolerability, pharmacokinetics (PK), and biomarkers of LB1410 in combination with lenvatinib, with or without LB4330.

Критерии исключения

• For cohorts containing lenvatinib, patients meeting any of the following criteria are ineligible:

• Radiographic (CT or MRI) evidence of tumor invasion around major blood vessels, or investigator judgment that the tumor is highly likely to invade major blood vessels during the study, leading to life-threatening hemorrhage;
• History of bleeding, coagulation disorders, or current use of warfarin, aspirin, or other antiplatelet agents;
• Urine protein ≥2+ and 24-hour urine protein quantification ≥1.0 g;
• Factors affecting oral drug absorption;
• Intestinal metastases or existing ≥Grade 3 gastrointestinal or non-gastrointestinal fistulas;
• History of hypertensive crisis or hypertensive encephalopathy.
• Pregnant or breastfeeding women.
• History of ≥Grade 3 immune-related adverse events (irAEs) during prior immunotherapy.
• Active autoimmune disease or symptomatic autoimmune disease.
• Any of the following prior treatments:

• Live or attenuated live vaccines within 4 weeks before the first dose;
• Immunomodulatory drugs (e.g., thymosin, interleukin-2, interferon) within 14 days before the first dose;
• History of allogeneic organ transplantation, allogeneic peripheral hematopoietic stem cell transplantation, or bone marrow transplantation.
• Positive HIV test, active syphilis, active hepatitis B virus (HBV) infection, or active hepatitis C virus (HCV) infection.
• Other malignancies within the past 3 year.
• Leptomeningeal metastasis, spinal cord compression, symptomatic or unstable brain metastases.
