Glow-in-the-Dark dye could help surgeons spot lung cancer
NCT ID NCT06713564
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early-stage trial tested a new fluorescent dye called LS301-IT in 24 people having lung cancer surgery. The dye is designed to attach to cancer cells and glow under a special light, helping surgeons see tumors more clearly. The main goals were to check safety and see how well the dye works at different doses and times before surgery.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- LS301-IT (a fluorescent dye that binds to cancer cells and glows under near-infrared light)
- What this could lead to
- If successful, this could give surgeons a real-time tool to see lung cancer during surgery, potentially helping them remove all cancerous tissue more precisely.
- What could go wrong
- This is an early phase 1 trial with only 24 people, focused mainly on safety. The dye may not work well in all patients, and there is a risk of allergic reactions or other side effects.

Inclusion Criteria: * ECOG performance status of 0 to 2 * Have a primary diagnosis, or a high clinical suspicion, for cancer in the lung based on CT, biopsy, or other imaging. * Are scheduled to undergo surgical thoracoscopy and resection of the lung. Exclusion Criteria: * Contraindications for surgery or any medical condition that in the opinion of the investigator could jeopardize the safety of the subject * No planned surgical use of any other fluorescent optical imaging agent, or exposure to another optical imaging agent within 8 weeks prior to surgery History of any drug-related hypersensitivity or anaphylactic reactions, including those attributed to indocyanine green (ICG) or other agents used in the study, or known shellfish allergies. Known sensitivity to near infrared light Patients with impaired renal function as defined by a creatinine clearance (CrCl) \<60 mL/min at Screening, according to the Cockcroft-Gault formula ((140 - age) × body weight/plasma creatinine × 72 (× 0.85 for female) History, or presence in the ECG at Screening, of any clinically significant abnormalities including cardiac conduction abnormalities such as Fridericia's corrected QTc interval (QTcF) \> 470 ms
