LK101 Combined With PD-1 or PD-L1 Monoclonal Antibody in the Treatment of Lung Cancer
- Conditions
- Advanced Lung Carcinoma
- Interventions
- Drug: LK101 injection (personlized neoantigen pulsed DC vaccine )
- Registration Number
- NCT05886439
- Brief Summary
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. The aim is to observe and evaluate the safety, tolerability and efficacy of LK101 injection combined with pembrolizumab or durvalumab respectively in the incurable NSCLC and SCLC.
- Detailed Description
This study is designed to evaluate the safety and efficacy of LK101 injection combined with pembrolizumab or durvalumab, which devided into 2 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.
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 and durvalumab (1500mg IV) Q3W in NSCLC and SCLC,respectively, until disease progression (PD), intolerable toxicity.
