Efficacy and Safety of a Single Dose of LS301-IT for Fluorescence Intraoperative Molecular Imaging (IMI) for Patients Undergoing Lung Cancer Resection for Non Small Cell Lung Cancer

April 16, 2026 updated by: Integro Theranostics

A Phase 2, Open-Label, Multicenter Study to Investigate the Efficacy and Safety of a Single Dose of LS301-IT for Fluorescence Intraoperative Molecular Imaging (IMI) for Lung Cancer Resection

The aim of this Phase 2 study is to investigate the efficacy and safety of a single dose of LS301-IT, a novel fluorescence imaging agent developed by Integro Theranostics (IT), administered by intravenous (IV) infusion in patients undergoing VATS (Video-Assisted Thoracoscopic Surgery) or RATS (Robotic-Assisted Thoracoscopic Surgery) resection of Stage I-II non-small cell lung cancer (NSCLC).

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

The primary objective of the study is to determine the proportion of subjects that have at least one Clinically Significant Event (CSE) using fluorescence imaging, defined as either the localization of the primary tumor when white light has failed to identify the tumor, the identification of a synchronous or occult pulmonary tumor with fluorescence only, or the identification of an inadequate surgical margin after resection. Secondary objectives include the determination of the sensitivity and positive predictive value (PPV) of LS301 fluorescence imaging in the identification of tumor using histopathology as the gold standard, and the assessment of the safety and tolerability of LS301-IT. Exploratory objectives include the determination of the "Clinical Impact Rate" defined as the proportion of cases when the surgeon changes the scope of the procedure based on LS301 fluorescence imaging, the assessment of the dosing interval prior to surgery, and the standardization of imaging during surgery and surgeon assessment of fluorescence.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

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
Clinically Significant Events
Time Frame: On the day of surgery

To determine the proportion of subjects that have at least one CSE where a CSE is defined as one of 3 possible clinical events:

a. Identification of primary tumor in situ with fluorescence IMI after non-ID with white light b. Identification of synchronous or occult lung tumors with fluorescence IMI after non-ID with white light c. Identification of tumor margin of resected specimen ex vivo within 10 mm of staple line with fluorescence IMI (both ≤5 mm and ≤10 mm will be assessed)
On the day of surgery

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
Sensitivity
Time Frame: day or surgery

Number of patients that are true positive divided by the number of patients that are true positive + false positive (True Positive/(True Positive + False Positive) of fluorescence IMI using intraoperative surgeon assessment with histopathology as the gold standard

Primary tumor identification rate
Time Frame: day of surgery
Proportion of patients that underwent flourescent imaging where the primary tumor was identified by flourescence

Propotion of the total number of synchronous or occult tumors identified by flourescent imaging
day of surgery
Close margin rate
Time Frame: day of surgery
