Study summary

The goal of this prospective, single-arm feasibility study is to evaluate the safety and feasibility of using Gleolan® (5-aminolevulinic acid), an FDA-approved drug currently used during brain tumor surgery, in adults with suspected kidney cancer undergoing partial nephrectomy. Gleolan has shown promise in improving the visualization of cancerous tissue, and this study aims to assess its potential use in urologic oncology. The main questions it aims to answer are:

  • Is Gleolan safe and well tolerated in patients with suspected kidney cancer undergoing partial nephrectomy?
  • Is the use of Gleolan feasible for fluorescence-guided identification of kidney cancer lesions during surgery?

Participants will:

  • Receive Gleolan before surgery according to the study protocol.
  • Undergo partial nephrectomy, during which fluorescence imaging will be used to evaluate the visualization of kidney tumor tissue.
  • Be monitored for safety outcomes and any adverse events before, during, and after surgery.

5-Aminolevulinic Acid (5-ALA), Gleolan, Kidney Cancer, Renal Cell Carcinoma, Partial Nephrectomy, Photodynamic Diagnosis (PDD), Fluorescence-Guided Surgery, Blue Light Imaging, Tumor Detection, Surgical Margins, Safety Profile, Adverse Events, Clinical Trial, Robotic Surgery, Pathology, Fluorescence Imaging, Renal Tumors, Pilot Study, Diagnostic Accuracy, Phase III Trial

This pilot clinical study aims to evaluate the safety and efficacy of 5-aminolevulinic acid (5-ALA; Gleolan) as a fluorescence-guided imaging agent for patients undergoing partial nephrectomy for suspected kidney cancer. Although 5-ALA is currently FDA-approved for visualization of high-grade gliomas during neurosurgery, emerging evidence suggests that it may also improve the detection of renal tumors through photodynamic diagnosis (PDD). The investigators hypothesize that oral administration of 5-ALA will cause kidney tumors to fluoresce under blue light, allowing surgeons to more easily identify tumors and assess resection margins while maintaining a favorable safety profile with minimal adverse events.

The study plans to enroll 10 adult patients aged 18 to 75 years who have kidney tumors amenable to standard-of-care partial nephrectomy. Eligible participants must have good performance status (ECOG 0-1) and adequate renal, hepatic, and hematologic function. Patients with significant cardiovascular disease, active liver disease, poorly controlled infections, pregnancy, porphyria-related hypersensitivity, or other major comorbidities will be excluded.

After informed consent is obtained, patients will undergo baseline laboratory testing including a comprehensive metabolic panel (CMP), liver function tests, lactate dehydrogenase (LDH), and γ-glutamyl transferase (GGT). On the day of surgery, participants will receive 20 mg/kg of oral 5-ALA dissolved in water approximately 2-4 hours before the procedure. Patients will be monitored preoperatively for known side effects such as nausea, vomiting, hypotension, and photosensitivity.

The surgical procedure will follow standard robotic partial nephrectomy techniques, with the addition of fluorescence imaging. Surgeons will first visualize the exposed tumor under white light and capture images. The operative field will then be examined using a specially modified blue-light imaging system to determine whether the tumor exhibits fluorescence. Following tumor excision under standard white light, the resection bed will again be examined with blue light to identify any residual fluorescent tissue that may indicate remaining tumor. If concerning fluorescence is observed, additional tissue margins may be resected and sent separately for pathological examination.

The primary outcomes include the ability of blue-light fluorescence imaging to detect kidney tumors and assist in evaluating residual disease. Investigators will compare tumor detection under white light versus blue light and calculate sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) using final surgical pathology as the gold standard. Receiver operating characteristic (ROC) curve analysis will be used to compare diagnostic performance between imaging modalities.

This proof-of-concept study seeks to determine whether 5-ALA fluorescence-guided surgery can improve intraoperative visualization of kidney tumors while maintaining an acceptable safety profile. Positive findings could support larger studies and potentially justify advancement to a Phase III clinical trial investigating fluorescence-guided kidney cancer surgery.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Patients aged 18 or older
  • Has indications for standard-of-care partial nephrectomy
  • Able to provide
  • Able to comply with study requirements

Exclusion criteria

Exclusion Criteria:

  • Known porphyria or to porphyrins
  • Pregnant or breastfeeding women
  • or ALT > 2x within 30 days prior to surgery
  • Participation in another study within 30 days
  • Known allergy or to 5-ALA or its components
Terms in these criteria, in plain language(6)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

ALT and AST (liver enzymes)

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.

Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.

ULN (upper limit of normal)

The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.

“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 18, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
