A Study of Neoadjuvant Tislelizumab Plus Lenvatinib in Resectable HCC at High Risk of Recurrence

Официальное название

Tislelizumab Plus Lenvatinib as Neoadjuvant Therapy for Patients With Resectable HCC at High Risk of Recurrence: a Prospective, Multicenter, Randomized Controlled Phase III Study

Обзор

This is a prospective, multicenter, randomized controlled, phase 3 study to explore the efficacy and safety of neoadjuvant tislelizumab plus lenvatinib in patients with resectable HCC at high risk of recurrence.

Подробное описание

Hepatectomy remains the primary curative treatment for HCC. However, the high rate of postoperative recurrence significantly limits long-term survival. For patients with resectable HCC at high risk of recurrence, strategies to reduce postoperative recurrence and prolong overall survival are needed. Previous studies have reported that combination regimens of immune checkpoint inhibitors plus antiangiogenic agents show promising efficacy and safety in the perioperative setting for HCC. This prospective, multicenter, randomized controlled phase 3 study aims to evaluate the efficacy and safety of neoadjuvant tislelizumab plus lenvatinib in patients with resectable HCC at high risk of recurrence.

Критерии исключения

• Hypertension inadequately controlled with antihypertensive therapy (systolic blood pressure ≥140 mmHg and/or diastolic blood pressure ≥90 mmHg); or history of hypertensive crisis or hypertensive encephalopathy.
• Known hypersensitivity to macromolecular protein preparations, or known allergy to tislelizumab, lenvatinib, or any of their excipients.
• Any active autoimmune disease or history of autoimmune disease (including but not limited to autoimmune hepatitis, interstitial pneumonitis, uveitis, enteritis/colitis, hepatitis, hypophysitis, vasculitis, nephritis, hyperthyroidism, hypothyroidism). Patients with vitiligo, or asthma that completely resolved in childhood and requires no intervention in adulthood, may be eligible. Patients with asthma requiring medical intervention with bronchodilators are not eligible.
