About this study

Official title: 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.

Read the 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.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing LK101 injection (personlized neoantigen pulsed DC vaccine ), Pembrolizumab and Durvalumab in people with Lung Cancer, run by Cancer Institute and Hospital, Chinese Academy of Medical Sciences at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 25 inclusion and 30 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 8 Dec 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Jie Wang, MD,PhD (13910704669, jiewang_hr@sina.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

DLT (time frame: Continuously throughout the study until 90 days after Termination of the treatment). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Dec 2025.
