ctDNA as a Biomarker for Treatment in Advanced NSCLC

August 2, 2022 updated by: Fuzhou General Hospital

A Prospective，Randomized, Multi-center Study to Identify the Patients Who Benefit From Short-course Chemotherapy (2 Cycles) in Combination With Immunotherapy as Treatment for Patients With Locally Advanced Unresectable or Metastatic Non-small Cell Lung Cancer (TLUNG)

The dynamic monitoring of circulating tumor DNA aims to evaluate the response and progression-free survival of short-course chemotherapy (2 cycles) combined with immunotherapy in patients with locally advanced unresectable or metastatic non-small cell lung cancer.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

For patients with locally advanced unresectable or metastatic non-small cell lung cancers, 4-6 cycles of chemotherapy plus immunotherapy with immune maintenance therapy is currently the standard treatment. Short-course chemotherapy (2 cycles) combined with immunotherapy has been proved effective in some patients. Recently, circulating tumor DNA (ctDNA) has been detected in the cell-free component of peripheral blood samples in advanced non-small cell lung cancers and many other solid tumors. To identify the patients who can benefit from the short-course chemotherapy (2 cycles) combined with immunotherapy, dynamic monitoring of ctDNA in both 4-6 cycles and 2 cycles chemotherapy patients could be a promising alternative test.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 80 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in ctDNA Level Following Chemo-immunotherapy
Time Frame: up to 1 year
Will be assessed for ctDNA levels at baseline, end of chemotherapy, and immunotherapy maintenance
up to 1 year

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Progression-free survival
Time Frame: up to 1 year
From the date of treatment until the date of progression of lung cancer or death from any other cause assessed up to 12 months
up to 1 year
Overall survival
Time Frame: up to 24 months
From the date of treatment until the date of death from any cause assessed up to 24 months
