LK101 Combined With PD-1 or PD-L1 Monoclonal Antibody in the Treatment of Lung Cancer

A Study of LK101 Combined With PD-1 or PD-L1 Monoclonal Antibody in the Treatment of Lung Cancer to Evaluate the Safety, Tolerability and Preliminary Efficacy

This is a open lable, single-center phase Ib/IIa study for patients with local advanced or metastastic NSCLC or ES-SCLC, who failed with previous anti-PD-1/PD-L1 therapy (cohort 1 and cohort 2) and for patients with ocal advanced or metastastic NSCLC received the first line treatment (cohort 3). The aim is to observe and evaluate the safety, tolerability and efficacy of LK101 injection combined with pembrolizumab, durvalumab or tislelizumab respectively in the incurable NSCLC and SCLC.

Study Overview

• Status: Recruiting
• Conditions: Lung Cancer
• Intervention / Treatment: Drug: LK101 injection (personlized neoantigen pulsed DC vaccine ); Drug: Pembrolizumab; Drug: Durvalumab; Drug: Tislelizumab

Detailed Description

This study is designed to evaluate the safety and efficacy of LK101 injection combined with pembrolizumab or durvalumab, which devided into 3 cohorts:

cohort 1: patients with locally advanced or metastastic (stage IIIB-IV) NSCLC who has progressed/relapsed after anti-PD-1/PD-L1 therapy. eligible subjects will receive LK101 injection and pembrolizumab treatment.

cohort 2: patients with extensive SCLC who failed with at least first-line standard therapy with PD-L1. eligible subjects will receive LK101 injection and durvalumab treatment.

cohort 3: patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) with no driver gene mutation and PD-L1 expression and have not experienced disease progression after receiving chemotherapy combined with an anti-PD-1 therapy.

LK101 will be administered in a prime-boost schedule of 4 priming vaccination followed by 3 booster vaccinations. For the priming phase: LK101 administered once a week at Days 1, 8, 15, 22. For the booster phase: total of 3 vaccinations will be given, Q3W from the end of priming dose. Treatment can be continued according to the investigator's evaluation, subsequent treatment is administered Q6W.

Patients will receive a combination of pembrolizumab(200mg IV) Q3W in cohort 1, durvalumab (1500mg IV) Q3W in cohort 2, tislelizumab (200mg) Q3W, respectively, until disease progression (PD), intolerable toxicity.
