Ameluz
(aminolevulinic acid hydrochloride)Dosage & Administration
Ameluz Prescribing Information
AMELUZ, in combination with photodynamic therapy (PDT) using BF-RhodoLED® or RhodoLED® XL lamp, a narrowband, red light illumination source, is indicated for lesion-directed and field-directed treatment of actinic keratoses (AKs) of mild-to-moderate severity on the face and scalp.
Important Administration Information
AMELUZ, in conjunction with lesion preparation, is only to be administered by a health care provider.
AMELUZ is for topical use only. Not for ophthalmic, oral, or intravaginal use.
Treat single lesions or an entire field affected by multiple lesions with AMELUZ, in combination with red light photodynamic therapy (PDT). PDT requires administration of both AMELUZ and BF-RhodoLED or RhodoLED XL light.
Refer to BF-RhodoLED or RhodoLED XL user manual for detailed lamp safety and operating instructions. Adhere to all safety instructions for both patient and medical personnel while conducting the PDT.
Recommended Dosage
Apply an approximately 1-mm thick layer of AMELUZ to skin lesion(s). Cover individual lesions or the entire AK-field with AMELUZ. Include approximately 5 mm of the surrounding skin. Do not exceed an application area of 60 cm2. Do not use more than 6 grams of AMELUZ (3 tubes) at one time.
Retreat lesions that have not completely resolved after 3 months after the initial treatment.
Administration Instructions
PDT is a multi-stage process:
Step 1. Preparation of Lesions
Before applying AMELUZ, carefully wipe all lesions with an ethanol or isopropanol-soaked cotton pad to ensure degreasing of the skin.
Figure 1A: Degreasing the skin
Thereafter, remove any scaling and crusts and gently roughen all lesion surfaces, taking care to avoid bleeding.
Figure 1B: Removal of scales and crusts
Step 2. Application of AMELUZ
Apply AMELUZ using glove protected fingertips or a spatula. Use sufficient amount of gel to cover individual lesions or the entire field:
- Lesion-directed treatment: Apply gel approximately 1 mm thick to one or more individual AK lesions and include approximately 5 mm of the surrounding healthy skin.
- Field-directed treatment: Apply gel approximately 1 mm thick to the treatment field. Apply gel to the lesions and the skin in-between the lesions. Additionally, cover approximately 5 mm of the surrounding healthy area.
Do not exceed an application area of 60 cm2 and do not use more than 6 grams of AMELUZ (3 tubes) at one time. The gel can be applied to healthy skin around the lesions. Avoid application near mucous membranes such as the eyes, nostrils, mouth, and ears (keep a distance of 1 cm from these areas). In case of accidental contact with mucous membranes, thoroughly rinse with water [see Warnings and Precautions (5.7)].
Allow the gel to dry for approximately 10 minutes before applying occlusive dressing.
Figure 2: Drug application
Step 3. Occlusion for 3 Hours
Cover the area where the gel has been applied with a light-blocking, occlusive dressing. Following 3 hours of occlusion, remove the dressing and wipe off any remaining gel.
Figure 3: Occlusion
Step 4. Illumination with Red Light
For patient and medical personnel, wear suitable protective eyewear during illumination. Avoid staring directly into the light source [see Warnings and Precautions (5.3)].
Illuminate the treatment area with the BF-RhodoLED or RhodoLED XL lamp immediately after removing occlusion and any remaining gel. BF-RhodoLED and RhodoLED XL lamps are red light sources with a narrow spectrum around 635 nm that deliver a light dose of approximately 37 J/cm2. Calibration by the operator is not needed; the illumination time is calculated automatically. Physical measures such as cooling with an air stream or nebulized water may help reduce pain during illumination.
Either the BF-RhodoLED or RhodoLED XL lamp can be used:
- BF-RhodoLED has an effective treatment area of 6 x 16 cm when an area of 8 x 18 cm is illuminated. Position the lamp head 5-8 cm from the skin’s surface. Larger areas can be illuminated in several steps.
- RhodoLED XL has a curved configuration with an effective treatment area up to 23 x 29 cm. Position the lamp head of the RhodoLED XL 11-14 cm from the skin’s surface. This usually allows a full-face illumination with the use of 5 panels. The smallest recommended number of panels to be used are 3 adjacent panels (see chapter 8.4.6 of RhodoLED XL user manual).
Healthy untreated skin surrounding the AK lesions does not need protection during illumination.
Figure 4A: Illumination with BF-RhodoLED
Figure 4B: Illumination with RhodoLED XL
If for any reason, the lesions cannot be illuminated within 3 hours after AMELUZ application, rinse off the gel with saline and water. For 2 days, protect the lesion sites and surrounding skin from sunlight or prolonged or intense light (e.g., tanning beds, sun lamps).
Topical gel: 10% aminolevulinic acid hydrochloride as a white-to-yellowish gel in 2-gram tubes.
Pregnancy
Risk Summary
There are no available data on AMELUZ use in pregnant women to inform a drug associated risk. Animal reproduction studies were not conducted with aminolevulinic acid. Systemic absorption of aminolevulinic acid in humans is negligible following topical administration of AMELUZ under maximal clinical use conditions [see Clinical Pharmacology (12.3)]. It is not expected that maternal use of AMELUZ will result in fetal exposure to the drug.
The background risk of major birth defects and miscarriage for the indicated population are unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.
Lactation
Risk Summary
No data are available regarding the presence of aminolevulinic acid in human milk, the effects of aminolevulinic acid on the breastfed infant or on milk production. However, breastfeeding is not expected to result in exposure of the child to the drug due to the negligible systemic absorption of aminolevulinic acid in humans following topical administration of AMELUZ under maximal clinical use conditions [see Clinical Pharmacology (12.3)]. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for AMELUZ and any potential adverse effects on the breastfeeding child from AMELUZ or from the underlying maternal condition.
Pediatric Use
Safety and effectiveness in pediatric patients below the age of 18 have not been established. AK is not a condition generally seen in the pediatric population.
Geriatric Use
Of the 384 subjects exposed to AMELUZ in randomized, multicenter clinical trials, 83% (318/384) of the subjects were 65 years old and over. No overall differences in safety or effectiveness were observed between these subjects and younger subjects, but greater sensitivity of some older individuals cannot be ruled out.
AMELUZ is contraindicated in patients with:
- Known hypersensitivity to porphyrins.
- Known hypersensitivity to any of the components of AMELUZ, which includes soybean phosphatidylcholine [see Warnings and Precautions (5.1)].
- Porphyria. AMELUZ use may cause uncontrolled phototoxic effects [see Warnings and Precautions (5.5)].
- Photodermatoses. PDT may worsen the phototoxic or photoallergic reactions [see Warnings and Precautions (5.5)].
Hypersensitivity
Several cases of hypersensitivity were reported during postmarketing use of AMELUZ prior to PDT illumination [see Adverse Reactions (6.2)]. If allergic reactions occur, clean the area of skin where the product was applied and institute appropriate therapy. Inform patients and their caregivers that AMELUZ may cause hypersensitivity, potentially including severe courses (anaphylaxis).
Transient Amnestic Episodes
Transient amnestic episodes have been reported during postmarketing use of AMELUZ in combination with photodynamic therapy. Inform patients and their caregivers that AMELUZ in combination with photodynamic therapy may cause transient amnestic episodes. Advise them to contact the healthcare provider if the patient develops amnesia after treatment.
Risk of BF-RhodoLED or RhodoLED XL Lamp Induced Eye Injury
BF-RhodoLED or RhodoLED XL lamp may cause eye irritation, glare, or injury. Before operating the lamp, personnel must refer to the user manual for specific warnings, cautions, and instructions. Eye exposure to the BF-RhodoLED or RhodoLED XL light must be prevented. Protective eye equipment must be used by patient, healthcare providers and any person present during the illumination period. Avoid staring directly into the light source.
Ophthalmic Adverse Reactions
Eyelid edema and dry eyes have occurred after PDT with AMELUZ. PDT with AMELUZ can cause ophthalmic adverse reactions. Avoid direct contact of AMELUZ with the eyes. Rinse eyes with water in case of accidental contact.
Increased Photosensitivity
AMELUZ increases photosensitivity. Avoid sunlight, prolonged or intense light (e.g., tanning beds, sun lamps) on lesions and surrounding skin treated with AMELUZ for approximately 48 hours following treatment, whether exposed to illumination or not. Concomitant use of AMELUZ with other known photosensitizing agents may increase the risk of phototoxic reaction to PDT [see Drug Interactions (7)].
Risk of Bleeding in Patients with Coagulation Disorders
AMELUZ has not been tested on patients with inherited or acquired coagulation disorders.
Take special care to avoid bleeding during lesion preparation in such patients [ see Dosage and Administration (2.3)]. Any bleeding must be stopped before application of the gel.
Risk of Mucous Membrane Irritation
AMELUZ can cause mucous membrane irritation. AMELUZ is intended for topical use only. Avoid direct contact of AMELUZ to the mucous membranes. Rinse with water in case of accidental contact.
The following adverse reactions are discussed in greater detail in other sections of the labeling:
- Hypersensitivity [see Warnings and Precautions (5.1)].
- Transient Amnestic Episodes [see Warnings and Precautions (5.2)].
- Risk of BF-RhodoLED or RhodoLED XL Lamp Induced Eye Injury [see Warnings and Precautions (5.3)].
- Ophthalmic Adverse Reactions [see Warnings and Precautions (5.4)].
- Increased Photosensitivity [see Warnings and Precautions (5.5)].
Clinical 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 clinical program for AMELUZ included three double-blind and placebo-controlled phase 3 trials (Trials 1, 2, and 3), enrolling a total of 299 subjects that were treated with narrow band light. Trial subjects were adults greater than or equal to 49 years of age, and the majority had Fitzpatrick skin type I, II, or III. No subjects had Fitzpatrick skin type V or VI. Approximately 86% of subjects were male, and all subjects were White.
For all three phase 3 trials, the enrolled subjects had mild to moderate AKs (Olsen grade 1 and 2) with 4 to 8 lesions on the face and scalp. Overall, 212 AMELUZ-treated subjects (n=32, n=55, and n=125) and 87 subjects receiving placebo (n=16, n=32, n=39) were illuminated with BF-RhodoLED or similar narrow spectrum lamps. For these trials, the maximal dose was one tube of AMELUZ (2 g) and the size of the application area was up to 20 cm2.
Local skin reactions at the application site were observed in about 99.5% of subjects treated with AMELUZ and narrow spectrum lamps. The most frequent adverse reactions during and after PDT were application site erythema, pain, burning, irritation, edema, pruritus, exfoliation, scab, induration, and vesicles.
Most adverse reactions occurred during illumination or shortly afterwards, were generally of mild or moderate intensity, and lasted for 1 to 4 days in most cases; in some cases, however, they persisted for 1 to 2 weeks or even longer. Severe pain/burning occurred in up to 30% of subjects. In one case, the adverse reactions required interruption or discontinuation of the illumination.
Table 1 presents the incidence of common (≥1%, <10%) and very common (≥10%) adverse reactions at the application site in randomized, multicenter trials which evaluated a maximal dose of one tube of AMELUZ (2 g) and an application area up to 20 cm2.
Adverse reaction | Vehicle | AMELUZ |

Common (≥1%, <10%) adverse reactions not at the application site for AMELUZ maximal dose of one tube (2 g) and application area up to 20 cm2 were headache, skin exfoliation, chills and eyelid edema.
Less common (≥0.1%, <1%) adverse reactions at the application site for AMELUZ maximal dose of one tube (2 g) and application area up to 20 cm2 were hemorrhage and swelling. The adverse reactions not at the application site were blister, feeling hot, pruritus, pyrexia, scab, nervousness, pain, petechiae, rash pustular, skin erosion and ulcer.
In a clinical trial designed to investigate the sensitization potential of aminolevulinic acid with 216 healthy subjects, 13 subjects (6%) developed allergic contact dermatitis after continuous exposure for 21 days with doses of aminolevulinic acid that were higher than doses normally used in the treatment of AK.
In two open label clinical trials to evaluate safety and tolerability, 116 subjects with actinic keratosis (AK) on the face and scalp were treated with three tubes (6 g) of AMELUZ applied to a 60 cm² area. Most adverse reactions observed were consistent with those reported in trials using one tube (2 g) of AMELUZ on a 20 cm² area (see Table 1). Additional reactions which occurred in ≥1% of subjects when three tubes (6 g) of AMELUZ were applied to a 60 cm² area included dry eyes, photosensitivity, and application site discoloration, dryness, papules, and fissures.
The frequencies of certain adverse reactions at the application site in these trials—exfoliation, itching, scabbing, and erosion—were more than 10% higher with the larger dose (three tubes, 6 g) and treatment area (60 cm²) compared to the frequencies observed in the trials for the smaller dose (one tube, 2 g) and area (20 cm²). Severe application site pain was reported by 41% of the subjects treated with three tubes (6 g) on a 60 cm² area. Most cases were reported during PDT illumination. A total of 15% of subjects discontinued illumination due to adverse reactions.
Postmarketing Experience
The following adverse reactions have been reported during post-approval use of AMELUZ. 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.
Skin and subcutaneous tissue disorders: allergic dermatitis, application site inflammation, application site discoloration.
Eye disorders: eye irritation, diplopia, ocular hyperemia, photophobia, and blurred vision.
General disorders and administration site conditions: fatigue.
Immune System disorders: hypersensitivity.
Nervous system disorders: dysaesthesia, transient amnestic episodes.
There have been no formal studies of the interaction of AMELUZ with other drugs. It is possible that concomitant use of other known photosensitizing agents such as St. John’s wort, griseofulvin, thiazide diuretics, sulfonylureas, phenothiazines, sulphonamides, quinolones and tetracyclines may enhance the phototoxic reaction to PDT [see Warnings and Precautions (5.3)].
AMELUZ (aminolevulinic acid hydrochloride) topical gel, 10% is a non-sterile white-to-yellowish gel. The gel formulation contains a nanoemulsion.
Aminolevulinic acid, a porphyrin precursor, is a white to off-white crystalline solid. It is readily soluble in water, methanol, and dimethylformamide. Its chemical name is 5-amino-4-oxo-pentanoic acid hydrochloride, molecular weight is 167.59 and molecular formula is C5H9NO3·HCl. The structural formula of aminolevulinic acid hydrochloride is represented below:
Each gram of AMELUZ contains 100 mg of aminolevulinic acid hydrochloride (equivalent to 78 mg aminolevulinic acid) as the active ingredient and the following inactive ingredients: xanthan gum, soybean phosphatidylcholine, polysorbate 80, medium-chain triglycerides, isopropyl alcohol, dibasic sodium phosphate, monobasic sodium phosphate, sodium benzoate and purified water.
Mechanism of Action
Photoactivation following topical application of AMELUZ occurs when aminolevulinic acid (prodrug) is metabolized to protoporphyrin IX (PpIX), a photoactive compound which accumulates in the skin. When exposed to red light of a suitable wavelength and energy, PpIX is activated resulting in an excited state of porphyrin molecules. In the presence of oxygen, reactive oxygen species are formed which causes damage to cellular components, and eventually destroys the cells. AMELUZ photodynamic therapy of AK lesions utilizes photoactivation of topically applied AMELUZ resulting from BF-RhodoLED or RhodoLED XL illumination, which provides a red light of narrow spectrum and a light dose of approximately 37 J/cm2.
Pharmacodynamics
The pharmacodynamics of AMELUZ in the treatment of actinic keratosis are unknown.
12.3 Pharmacokinetics
Aminolevulinic acid acts as a prodrug to the photoactive metabolite protoporphyrin IX (PpIX).
Pharmacokinetics (PK) of aminolevulinic acid and PpIX were evaluated in two trials:
In the first trial, a single dose of one entire tube of AMELUZ (2 grams) was applied under occlusion for 3 hours followed by PDT to a total area of 20 cm2 in 12 adult subjects with mild to moderate AK with at least 10 AK lesions on the face or forehead. The mean ± SD baseline plasma aminolevulinic acid concentration was 20.16 ± 16.53 ng/mL. In most subjects, an up to 2.5-fold increase of aminolevulinic acid plasma concentrations was observed during the first 3 hours after AMELUZ application. The mean ± SD area under the concentration time curve (AUC0-t) and maximum concentration (Cmax) for baseline corrected aminolevulinic acid (n=12) were 142.83 ± 75.50 ng·h/mL and 27.19 ± 20.02 ng/mL, respectively. The median Tmax (time at which Cmax occurred) was 3 hours.
The mean ± SD baseline plasma PpIX concentration was 3.27 ± 2.40 ng/mL (n=12). The majority (about 55%) of the PpIX concentrations were below the limit of quantification (LOQ = 1 ng/mL) and baseline corrected values were negative in all subjects except for one. The baseline corrected AUC0-t and Cmax in the single subject was 0.07 ng·h/mL and 0.29 ng/mL, respectively.
In the second trial, a single dose of three entire tubes of AMELUZ (6 grams) was applied under occlusion for 3 hours followed by PDT to a total area of 60 cm2 in 16 adult subjects with mild to severe AK with at least 12 AK lesions on the face and scalp. The mean ± SD baseline plasma aminolevulinic acid concentration was 13.53 ± 1.58 ng/mL. In most subjects, an up to 2.5-fold increase of aminolevulinic acid plasma concentrations was observed during the first 3 hours after AMELUZ application. The mean ± SD area under the concentration time curve (AUC0-t) and maximum concentration (Cmax) for baseline corrected aminolevulinic acid (n=16) were 134.24 ± 87.97 ng·h/mL and 33.85 ± 21.85 ng/mL, respectively. The median Tmax (time at which Cmax occurred) was 3 hours.
The mean ± SD baseline plasma PpIX concentration was 1.93 ± 0.42 ng/mL (n=15). The mean ± SD baseline corrected Cmax of PpIX was 0.67 ± 0.78 ng/mL (n=13) with a median Tmax of 4 hours. The baseline corrected PpIX concentrations in 14 of 15 subjects were < 1 ng/mL.
Carcinogenesis, Mutagenesis, Impairment of Fertility
Long-term studies to evaluate the carcinogenic potential of AMELUZ or aminolevulinic acid have not been performed.
Aminolevulinic acid revealed no evidence of mutagenic or clastogenic potential based on the results of three in vitro genotoxicity tests (Ames assay, HPRT test in V79 cells, and Human lymphocyte chromosomal aberration assay) and one in vivo genotoxicity test (mouse micronucleus assay). These genotoxicity studies were conducted without exposure to light. There is a literature report that indicates that aminolevulinic acid may cause genotoxic effects in the presence and in the absence of activating light. These genotoxic effects are likely caused by the formation of reactive oxygen species.
Animal fertility studies have not been conducted with aminolevulinic acid because of the negligible systemic absorption of aminolevulinic acid in humans following topical administration of AMELUZ under maximal clinical use conditions.
The efficacy and safety of AMELUZ in combination with PDT using a narrow spectrum (red light lamp) source were evaluated in three randomized, multicenter trials (Trials 1, 2, and 3). Trials 2 and 3 were vehicle-controlled and double-blind. Trial 1 was double-blind with respect to vehicle and observer-blind regarding the active comparator arm. All clinical trials included a follow-up assessment after 6 and 12 months.
In these trials, 212 subjects with 4 to 8 mild to moderate AK lesions on the face/forehead and/or bald scalp were treated with up to one tube (2 grams) of AMELUZ on an application area up to 20 cm² and a narrow band spectrum lamp. Subjects ranged from 49 to 87 years of age (mean 71 years), and 92% had Fitzpatrick skin type I, II, or III. No subjects had Fitzpatrick skin type V or VI. Approximately 86% of subjects were male, and all subjects were White.
All sessions were comprised of lesion preparation to roughen the surface and remove crusts, application of AMELUZ with occlusion for 3 hours, and removal of the residual gel. Subsequently, the entire treatment area was illuminated with a narrow spectrum red light source, a lamp of either 630 nm or 633 nm and a light dose of approximately 37 J/cm2. In Trial 3, illumination was performed with BF-RhodoLED, a red light source with a narrow spectrum around 635 nm and a light dose of approximately 37 J/cm2.
In all trials, the lesions that were not completely cleared 12 weeks after the initial treatment were treated a second time with an identical regimen. In the trials, 42% (88/212) of subjects needed a second treatment.
The primary endpoint for all trials was complete clearance 12 weeks after the last PDT. The results of Trials 1, 2 and 3 are presented in Table 2.
AMELUZ | Vehicle | |
Trial 1 | 106/125 (85%) | 5/39 (13%) |
Trial 2 | 27/32 (84%) | 2/16 (13%) |
Trial 3 | 50/55 (91%) | 7/32 (22%) |
Subjects who achieved complete clearance at 12 weeks after the last PDT entered a 12-month follow-up period. In the three trials, subjects who received AMELUZ with the narrowband PDT and achieved complete clearance 12 weeks after the last PDT had recurrence rates of 14%, 11%, and 25%, respectively (at 6 months) and 40%, 22%, and 37%, respectively (at 12 months).
Recurrence was defined as the percentage of subjects with at least one recurrent lesion during the 6-month or 12-month follow-up period in subjects with completely cleared lesions 12 weeks after the last PDT.

Version 1.8 SW_G2
Mechanism of Action
Photoactivation following topical application of AMELUZ occurs when aminolevulinic acid (prodrug) is metabolized to protoporphyrin IX (PpIX), a photoactive compound which accumulates in the skin. When exposed to red light of a suitable wavelength and energy, PpIX is activated resulting in an excited state of porphyrin molecules. In the presence of oxygen, reactive oxygen species are formed which causes damage to cellular components, and eventually destroys the cells. AMELUZ photodynamic therapy of AK lesions utilizes photoactivation of topically applied AMELUZ resulting from BF-RhodoLED or RhodoLED XL illumination, which provides a red light of narrow spectrum and a light dose of approximately 37 J/cm2.
