🎯 Indications and Usage ▾
1 INDICATIONS AND USAGE Gleolan is indicated in patients with glioma [suspected World Health Organization (WHO) Grades III or IV on preoperative imaging] as an adjunct for the visualization of malignant tissue during surgery. Gleolan is an optical imaging agent indicated in patients with glioma (suspected World Health Organization Grades III or IV on preoperative imaging) as an adjunct for the visualization of malignant tissue during surgery. ( 1 )
⏱️ Dosage and Administration ▾
2 DOSAGE AND ADMINISTRATION For oral use only ( 2.1 ) Recommended reconstituted oral dose of Gleolan is 20 mg/kg. ( 2.1 ) Administer Gleolan to patient orally 3 hours (range 2 to 4 hours) before anesthesia. ( 2.1 ) See Full Prescribing Information for reconstitution information. ( 2.2 ) Use appropriate visualization techniques with appropriate surgical microscopes and light source filters. ( 2.4 )
2.1Recommended Dose For oral use only The recommended oral dose of reconstituted Gleolan is 20 mg / kg body weight. More than 1 vial may be required.
2.2Reconstitution of Gleolan Gleolan powder must be reconstituted prior to administration by a healthcare provider according to the following instructions: Determine the total number of vials needed to achieve the intended dose for the patient according to the equation below (rounded up to the nearest whole vial): # of vials = Patient Body Weight (kg) 75 kg / vial Completely remove the white cap and aluminum crimp seal from each vial. Remove and retain the rubber stopper from the vial. Using an appropriate volumetric measuring device (e.g., flask, graduated cylinder, dosing syringe), measure 50 mL of drinking water and add to each vial containing 1,500 mg of Gleolan.
Gently swirl the vial to completely dissolve the powder. The resulting reconstituted solution (30 mg of Gleolan per mL) is clear and colorless to slightly yellowish. If required, replace the stopper and store reconstituted solution for up to 24 hours at room temperature prior to administration.
2.3Gleolan Administration Gleolan is for ORAL USE ONLY. The reconstituted Gleolan solution is administered according to the following steps: Calculate the administration volume, in mL, to achieve the intended dose according to the following equation: Administration Volume (mL) = Patient Body Weight (kg) * 20 mg/kg 30 mg/mL Transfer the entire contents of the prepared vial(s) into an appropriate dosing container (e.g., oral medicine bottle); ensure the entire contents of the vials are transferred. After transfer, discard the empty vial(s).
Using a disposable volumetric syringe, remove the administration volume of reconstituted Gleolan solution from the dosing container and transfer to a separate oral dosing container. Discard unneeded volume of Gleolan solution. Administer orally 3 hours (range 2 to 4 hours) prior to induction of anesthesia.
2.4Imaging Instructions Gleolan should be used with a standard surgical operating microscope adapted with a blue light emitting light source (power density 40-80 mW/cm 2 ) and ancillary excitation and emission filters to visualize fluorescence excitation in the wavelength of 375 to 440 nm and for observation from 620 to 710 nm. Filters transmit porphyrin fluorescence as red-violet, as well as a fraction of backscattered blue excitation light necessary for distinguishing nonfluorescing tissue. Gleolan should only be used by neurosurgeons who have completed a training program on use of fluorescence in surgery.
Training is provided by the distributor.

⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Phototoxic reactions: Do not administer phototoxic drugs (St. John's wort, griseofulvin, thiazide diuretics, sulfonylureas, phenothiazines, sulphonamides, quinolones and tetracyclines), and topical preparations containing ALA for 24 hours during the perioperative period. Reduce exposure to sunlight or room lights for 48 hours after oral administration of Gleolan.
( 5.1 , 7 ) Risk of misinterpretation: Non-fluorescing tissue in the surgical field does not rule out the presence of tumor. ( 5.2 , 14 )
5.1Risk of Phototoxic Reaction Due to the risk of phototoxic reactions, do not administer phototoxic drugs (St. John's wort, griseofulvin, thiazide diuretics, sulfonylureas, phenothiazines, sulphonamides, quinolones and tetracyclines), and topical preparations containing ALA for 24 hours during the perioperative period [see Drug Interactions (7) ] . Reduce exposure to sunlight or room lights for 48 hours after administration of Gleolan.
5.2Risk of Misinterpretation Errors may occur with the use of Gleolan for intraoperative visualization of malignant glioma, including false negatives and false positives. Non-fluorescing tissue in the surgical field does not rule out the presence of tumor in patients with glioma [see Clinical Studies (14) ] . Fluorescence may be seen in areas of inflammation or metastases from other tumor types.
5.3Hypersensitivity Reactions Hypersensitivity reactions, including serious hypersensitivity reactions have occurred; these reactions include anaphylactic shock, swelling, and urticaria [see Contraindications (4) , Adverse Reactions (6.2) ] . Always have cardiopulmonary resuscitation personnel and equipment readily available and monitor all patients for hypersensitivity reactions.
🤒 Adverse Reactions ▾
6 ADVERSE REACTIONS Adverse reactions occurring in >1% of patients in the week following surgery were pyrexia, hypotension, nausea, and vomiting. ( 6.1 ) Adverse reactions occurring in < 1% of patients in the first 6 weeks after surgery were: chills, photosensitivity reaction, solar dermatitis, hypotension, abnormal liver function test, and diarrhea. ( 6.1 ) Neurologic events related to the surgical procedure occurred in 29% of patients and included: aphasia, hemiparesis, hemianopia, headache, seizure, hemiplegia, monoparesis, hypoesthesia, and brain edema.
( 6.1 ) Elevated liver enzymes occurred in clinical studies. There were no cases of liver failure. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact NXDC toll-free at (844) 517-5252 and [email protected] or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.
6.1Clinical Trial Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The safety of Gleolan is supported by data from 5 open label clinical studies, which included 527 patients with glioma who received ALA HCl. Adverse reactions that occurred in > 1% of patients in the week following surgery were pyrexia, hypotension, nausea, and vomiting.
Adverse reactions occurring in the first 6 weeks after surgery in < 1% of patients were: chills, photosensitivity reaction, solar dermatitis, hypotension, abnormal liver function test, and diarrhea. One patient experienced respiratory failure due to drug overdose [see Overdosage (10) ] . Neurologic Events Nervous system disorders occurred in 29% of patients within the first week after surgery.
Events occurring in > 1% of patients included aphasia (8%), hemiparesis (7.8%), hemianopsia (3.2%), headache (2.7%), seizure (1.9%), hemiplegia (1.9%), monoparesis (1.3%) and hypoesthesia (1.1%). Brain edema occurred in < 1 % of patients in the first 6 weeks after surgery. In a randomized clinical trial (Study 3), the numbers of serious neurologic adverse events in the post operative period were higher in patients randomized to ALA fluorescence arm compared to the control arm.
An imbalance was notable for the adverse events aphasia, ataxia, convulsion and hemianopsia, and is likely related to the higher amount of brain resection performed in the ALA arm. At longer follow up periods, the numbers between the two arms appeared similar [see Clinical Trials (14) ] . Elevated Liver Enzymes Worsening of ≥ 2 Common Toxicity Criteria (CTC) grades in alanine aminotransferase (ALT) and gamma-glutamyl transferase (GGT) occurred in (15.8% and 11.6%, respectively) within the first week after surgery.
Absolute levels ranged from 2 times to greater than 10 times the upper limit of normal (ULN) for each parameter. At 6 weeks, ALT remained elevated in 2.9% of patients (range 2 to greater than 5 X ULN), and GGT was elevated in 7.5% of patients (range 2 to greater than 10 X ULN). No cases of liver failure occurred.
6.2Post Marketing Experience The following adverse reactions are among those that have been identified during post-approval use of Gleolan outside of the United States. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Immune Disorders : anaphylactic shock, angioedema, drug eruption, urticaria, erythema.
Metabolism and Nutrition Disorders : metabolic acidosis.
🔄 Drug Interactions ▾
7 DRUG INTERACTIONS Phototoxic Drugs Patients exposed to a photosensitizing agent may experience a phototoxic skin reaction (severe sunburn). Due to the risk of possible phototoxic reactions, avoid administering phototoxic drugs such as St. John's wort, griseofulvin, thiazide diuretics, sulfonylureas, phenothiazines, sulphonamides, quinolones and tetracyclines, and topical preparations containing ALA for 24 hours before and after administration of Gleolan.
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS
8.1Pregnancy Risk Summary There are no available human data on Gleolan in pregnant women to inform a drug associated risk of adverse developmental outcomes. In animal reproduction studies, no adverse developmental effects were observed with oral ALA HCl administration to pregnant rabbits during organogenesis at doses 3 times the maximum recommended human oral dose (see Data) . The estimated background risk of major birth defects and miscarriage for the indicated populations are unknown.
All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively. Animal data ALA HCl was administered to rabbits at oral doses of 15, 50 and 150 mg/kg/day [approximately 0.1, 0.6, and 3 times the maximum human recommended dose (MHRD), respectively based on AUC comparisons] from gestation days 6-18.
The no-observed-adverse-effect level (NOAEL) for maternal toxicity was 50 mg/kg/day and the NOAEL for embryo-fetal developmental toxicity was 150 mg/kg/day.
8.2Lactation Risk summary There are no data on the presence of ALA HCl in either human or animal milk, the effects on the breastfed infant, or the effects on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for Gleolan and any potential adverse effects on the breastfed infant from Gleolan or from the underlying maternal condition. Clinical Considerations To decrease exposure to Gleolan to the breastfed infant, advise a lactating woman to pump and discard breast milk after the administration of Gleolan for 24 hours (i.e., 5 to 6 half-lives).
8.4Pediatric Use The safety and effectiveness of Gleolan in pediatric patients have not been established.
8.5Geriatric Use Of 527 subjects in clinical studies of Gleolan, 182 were 65 to < 75 years of age and 7 were ≥ 75 years of age. No overall differences in safety or effectiveness were observed between these subjects and younger subjects, and other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out. No dose adjustment is required in elderly patients.
8.6Patients with Renal Impairment Because approximately one third of the ALA dose is excreted in urine as parent drug, ALA clearance may be reduced in patients with renal impairment; it is not known if dose adjustment is needed [see Clinical Pharmacology (12.3) ] .
8.7Patients with Hepatic Impairment The contribution of the liver to the elimination of ALA following Gleolan dosing is unknown. ALA clearance may be reduced in patients with hepatic impairment; it is not known if dose adjustment is needed [see Clinical Pharmacology (12.3) ] .

🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action ALA occurs endogenously as a metabolite that is formed in the mitochondria from succinyl-CoA and glycine. Exogenous administration of ALA leads to accumulation of the ALA metabolite PpIX in tumor cells. The reason for the accumulation of PpIX in neoplastic brain tissue is not known.
During glioma surgery, Gleolan is used with an operating microscope adapted with a blue emitting light source (power density 40-80 mW/cm 2 ) and filters for excitation light of wavelength 375 to 440 nm, and observation at wavelengths of 620 to 710 nm. This allows tumor tissue to be visualized as red fluorescence. Tissue lacking sufficient PpIX concentrations appears blue.
12.2Pharmacodynamics The effect of the timing of the Gleolan dosing on fluorescence intensity in brain tissue is unknown. The relationship between systemic ALA plasma concentrations at the time of visualization and fluorescence intensity in brain is also unknown. The dose of 20 mg / kg provided stronger ALA-induced fluorescence in glioma tissue by both visual and spectrophotometric assessment compared to lower doses tested.
Cardiac Electrophysiology Administration of the approved recommended dose of Gleolan did not prolong the QT interval to any clinically relevant extent.
12.3Pharmacokinetics In 12 healthy subjects, the mean half-life of ALA following the recommended dose of Gleolan solution was 0.9 ± 1.2 hours (mean ± std dev) with a range of 0.8 to 1.3 hours. Maximum concentrations of the PpIX metabolite (T max for PpIX) occurred with a median of 4 hours and a range of 1.2 to 7.8 hours. The elimination half-life of PpIX was 3.6 ± 1.8 hours (mean ± std dev) with a range of 1.2 to 7.8 hours.
Absorption In 12 healthy subjects, the absolute bioavailability of ALA following the recommended dose of Gleolan solution was 100.0% ± 1.1 with a range of 78.5% to 131.2%. Maximum ALA plasma concentrations were reached with a median of 0.8 hour (range 0.5 – 1.0 hour). Distribution In in vitro experiments using ALA concentrations up to approximately 25% of the maximal concentration that occurs in plasma following the recommended dose of Gleolan solution, the mean protein binding of ALA was 12%.
Elimination Metabolism Exogenous ALA is metabolized to PpIX, but the fraction of administered ALA that is metabolized to PpIX is unknown. The average plasma AUC of PpIX is less than 6% of that of ALA. Excretion In 12 healthy subjects, excretion of parent ALA in urine in the 12 hours following administration of the recommended dose of Gleolan solution was 34 ± 8% (mean ± std dev) with a range of 27% to 57%.
Specific Populations The effect of renal or hepatic impairment on the pharmacokinetics of ALA following Gleolan administration is unknown. Drug Interaction Studies In vitro studies suggest that phenytoin and other anti-convulsants may decrease cellular PpIX accumulation following Gleolan dosing. ALA is not an inhibitor of CYP1A2, 2B6, 2C8, 2C9, 2C19, 2D6, or 3A.
