Could a dye given days before surgery help doctors spot hidden tumors?
NCT ID NCT07469202
First seen Jun 27, 2026 · Last updated Aug 19, 2026 · Updated 2 times
Summary
This study tests whether giving a dye called Cytalux a few days before surgery works as well as giving it closer to the operation. The dye makes tumors glow under a special light, helping surgeons remove them more completely. About 106 adults with suspected lung cancer or confirmed ovarian cancer will take part. The goal is to see if the longer window is just as effective for spotting cancerous and non-cancerous lesions.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Male and female patients 18 years of age and older 2. Primary diagnosis, or a high clinical suspicion, of cancer in the lung warranting surgery based on CT/PET or other imaging obtained within 4 months of the screening visit, or have a primary diagnosis for ovarian cancer 3. Scheduled to undergo surgical thoracoscopy for wedge resection or anatomic lung resection, or ovarian cancer debulking/cytoreduction 4. Willingness of research participant or legal guardian/representative to give written informed consent Exclusion Criteria: 1. History of anaphylactic reactions to products containing indocyanine green for near infrared imaging. Subjects with a medical history of 'idiopathic anaphylaxis' will require evaluation. 2.

Presence of any psychological, familial, sociological condition or geographical challenges potentially hampering compliance with the study protocol or follow-up schedule 4. Known sensitivity to fluorescent light 5. Impaired renal function defined as eGFR\< 50 mL/min/1.73m2 6. Impaired liver function defined as values \> 3x the upper limit of normal (ULN) for alanine aminotransferase (ALT) or aspartate aminotransferase (AST), alkaline phosphatase (ALP), or \>2x ULN for total bilirubin excluding those patients with Gilbert's syndrome 7. Pregnant and/or lactating women 8. Administration of folate, folic acid, or folate-containing supplements 48 hours before administration of Cytalux™ (pafolacianine)
