Label name AMELUZ 10% GEL Ingredient Aminolevulinic Acid Hcl
📖 What it is MedlinePlus · NLM

Aminolevulinic acid is used with light therapy to treat actinic keratoses (small crusty or scaly patches of skin formed by exposure to sunlight; can turn into cancer if not treated) of the face,scalp, or upper arms. Aminolevulinic acid is in a class of medications called photosensitizing agents. Photosensitizing agents combined with light therapy is called phytodynamic therapy (PDT). The light activates the drug which then kills abnormal cells.

Pricing

A drug doesn't have one price. Each row is a different public payment system, and none is what you'd pay at the counter — that depends on your insurance. The ⓘ on each row explains what it measures.

Where does this data come from?
NADAC (National Average Drug Acquisition Cost) is the CMS weekly pharmacy-acquisition-cost survey — what pharmacies pay. ASP (Average Sales Price) is the CMS Medicare Part B drug-payment file, published quarterly. Medicaid pays is computed by us from CMS State Drug Utilization Data (total reimbursed ÷ units, trailing 12 months) — gross of rebates and inclusive of dispensing fees, so it reflects what Medicaid paid, not an acquisition cost. Medicare drug plans pay is the median negotiated point-of-sale unit cost across plans listing this NDC in the CMS quarterly Prescription Drug Plan pricing files, before rebates. The VA pays is the federal contract price (FSS, and the statutory Big 4 ceiling where listed) from the VA National Acquisition Center pharmaceutical price file. All are free public government data; each measures a different payer, so the figures are not directly comparable.

Why the date isn’t exact: Generic timing can change because patents may be challenged, settled, licensed, added, removed, or worked around with a narrower label — and FDA approval does not always mean a pharmacy can get the generic today.

LOE
Substance patent Formulation patent Method-of-use patent Exclusivity Pediatric +6mo
🏛️FDA exclusivity
FDA-granted marketing protection. It’s separate from patents and may be shorter than patent protection.
🧪Product / substance patents
Patents covering the active ingredient, product, formulation, or related drug features.
🎯Method-of-use patents
Patents covering specific approved uses. These can sometimes be carved out with a “skinny label,” but not always.
🛈 What do these terms mean?
Patent
Legal protection listed in the Orange Book that may delay generic approval or launch. Issued by the U.S. Patent & Trademark Office.
Substance patent
Covers the active drug molecule itself — the hardest to design around. A generic generally can’t launch until it expires.
Formulation (product) patent
Covers a specific formulation or dosage form. A generic can sometimes work around it with a different formulation.
Method-of-use patent
A patent covering one specific approved use of the drug — not necessarily the whole molecule. A generic can sometimes launch with a “skinny label” that carves out the protected use and keeps the others.
Skinny label
A generic label that omits a still-patented use when the FDA allows it — letting a generic reach the market for the unprotected uses.
Exclusivity
FDA-granted marketing protection, separate from patents — e.g. 5-yr new chemical entity, 7-yr orphan drug, or a +6-month pediatric extension.
Paragraph IV
A generic applicant’s formal challenge to a listed patent. It can potentially lead to earlier generic entry, but often involves litigation or a settlement.
RLD / RS
Reference Listed Drug — the brand product the FDA uses as the reference for generic applications. Reference Standard — the product the FDA expects generics to compare against in bioequivalence testing.
TE / AB rating
FDA therapeutic-equivalence rating. An AB rating generally means the FDA considers a generic therapeutically equivalent to — and substitutable for — the brand.
LOE (loss of exclusivity)
The latest patent or exclusivity currently listed — the loss-of-exclusivity / latest-listed-protection date shown on this page. Paragraph-IV challenges and settlements can move the real date earlier; FDA approval and a manufacturer’s decision to market can move it later.

Built from the FDA Orange Book. The bars above are scaled to each protection’s expiry; the red LOE marker is the last one to lapse.

Common questions
Is there a generic version of AMELUZ 10% GEL?
No FDA-approved generic equivalent is currently listed in the FDA Orange Book for AMELUZ 10% GEL. Based on the patents and exclusivity currently listed, the Orange Book estimate is that full-label generic entry may be delayed until Dec 2043 — an estimate, not a guaranteed launch date.
The FDA approved a generic — why can’t I get it at my pharmacy yet?
FDA approval and pharmacy availability are two different things. The FDA can approve a generic years before it actually reaches pharmacies, because the brand company may still hold patents or have a settlement that delays the launch. A manufacturer also has to choose to make and sell it, and have supply ready. So a drug can be “FDA-approved generic exists” and still be brand-only at the counter today.
Why do different websites show different generic release dates?
Generic availability is not based on one single date. Some sources use the first exclusivity expiration, some use the last product patent, and others use the latest method-of-use patent. Patent challenges, settlements, licenses, and label carve-outs can also change the real-world launch date. This page shows the underlying Orange Book dates so you can see why estimates may differ.
What does “FDA listed” mean?
It means the product appears in the FDA’s official NDC directory. That’s a good sign a product exists and is intended for the U.S. market, but on its own it does not confirm a pharmacy can fill it today. Where we have recent retail pricing data (NADAC) for a product, we label it “Availability likely” instead.
What does a patent or protection date mean here?
It’s the latest date currently listed in the FDA Orange Book for a patent or exclusivity on the brand product. It can affect when a full generic version becomes widely available — but it is not a guaranteed generic launch date. Generics sometimes arrive earlier (through a settlement or patent challenge) or later (a manufacturer still has to make and sell one).
What does “current Orange Book estimate” mean?
It means we are using the latest patent and exclusivity dates currently listed in the FDA Orange Book. It is not a guaranteed launch date.
Can a generic come out before the last patent expires?
Sometimes. A generic company may challenge a patent, settle with the brand manufacturer, receive a license, or obtain approval with a narrower label that avoids a patented use. In other cases, the last listed protection may delay full-label generic competition.
Can a generic come out after the listed dates?
Yes. Even after patents or exclusivity expire, a generic still needs FDA approval and a manufacturer must choose to market it. Supply, litigation, business decisions, or regulatory issues can delay actual availability.
What is the difference between patents and exclusivity?
Patents are legal protections usually issued by the U.S. Patent and Trademark Office. FDA exclusivity is marketing protection granted by the FDA. They are separate, and either one can affect generic timing.
Why are there multiple patent dates?
One drug can have several patents covering different things: the active ingredient, a formulation, a manufacturing process, or a specific approved use. That is why a page may show several expiration dates instead of one simple generic date.
Built from FDA Orange Book patent and exclusivity data. Dates are refreshed from public FDA data when available; the marker is max(latest patent expiry, latest exclusivity expiry). Paragraph-IV settlements and first-filer 180-day exclusivity can shift the real date; a method-of-use patent may allow an earlier skinny-label generic for non-protected indications. Generic launch timing is an estimate, not a guarantee.
Where does this data come from?
Patents and exclusivity from the FDA Orange Book (small-molecule drugs), refreshed from public FDA data. Generic launch timing is an estimate, not a guarantee.

1. INDICATIONS AND USAGE 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. AMELUZ, a porphyrin precursor, in combination with photodynamic therapy using BF-RhodoLED or RhodoLED XL lamp, is indicated for the lesion-directed and field-directed treatment of actinic keratoses (AK) of mild-to-moderate severity on the face and scalp ( 1 ).

⏱️ Dosage and Administration ~3 min read ▾

2. DOSAGE AND ADMINISTRATION Administer AMELUZ only by a health care provider ( 2.1 ). AMELUZ is for topical use only ( 2.1 ).

Use AMELUZ in combination with red light photodynamic therapy (PDT). See BF-RhodoLED or RhodoLED XL user manual for detailed lamp safety and operating instructions ( 2.1 ). Photodynamic therapy with AMELUZ involves preparation of lesions, application of the product, occlusion and illumination with BF-RhodoLED or RhodoLED XL lamp ( 2.3 ).

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 cm 2 . Do not use more than 6 grams of AMELUZ (3 tubes) at one time ( 2.2 ). Retreat lesions that have not completely resolved 3 months after the initial treatment ( 2.2 ).

2.1Important 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.

2.2Recommended 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 cm 2 . 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.

2.3Administration 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 cm 2 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.

5. WARNINGS AND PRECAUTIONS Hypersensitivity: Hypersensitivity reactions have been reported with the use of AMELUZ prior to photodynamic therapy (PDT). If allergic reaction occurs, wash off AMELUZ and institute appropriate therapy ( 5.1 ).

Transient Amnestic Episodes: Transient amnestic episodes have been reported with use of AMELUZ in combination with PDT. Advise patients to contact their healthcare provider if amnesia or confusion occurs after treatment ( 5.2 ). Risk of BF-RhodoLED or RhodoLED XL Lamp Induced Eye Injury: Patients and healthcare providers must wear protective eyewear before operating BF-RhodoLED or RhodoLED XL lamp ( 5.3 ).

Ophthalmic Adverse Reactions: Avoid direct contact of AMELUZ with the eyes ( 5.4 ). Increased Photosensitivity: Protect treated lesions from sunlight exposure for 48 hours post treatment ( 5.5 ). Risk of Bleeding in Patients with Coagulation Disorders: Take special care to avoid bleeding during lesion preparation in patients with inherited or acquired coagulation disorders ( 5.6 ).

Mucous Membrane Irritation: Avoid direct contact of AMELUZ with the mucous membranes ( 5.7 ).

5.1Hypersensitivity 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).

5.2Transient 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.

5.3Risk 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.

5.4Ophthalmic 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.

5.5Increased 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) ] .

5.6Risk 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.

5.7Risk 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.

6. ADVERSE REACTIONS 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) ] .

Most common adverse reactions (≥10%) were application site erythema, pain/burning, irritation, edema, pruritus, exfoliation, scab, induration, and vesicles ( 6.1 ). To report SUSPECTED ADVERSE REACTIONS, contact Biofrontera Inc. at 1-844-829-7434 or FDA at 1-800-332-1088 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 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 cm 2 . 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 cm 2 .

8. USE IN SPECIFIC POPULATIONS

8.1Pregnancy 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.

8.2Lactation 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.

8.4Pediatric 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.

8.5Geriatric 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.

12. CLINICAL PHARMACOLOGY

12.1Mechanism 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/cm 2 .

12.2Pharmacodynamics The pharmacodynamics of AMELUZ in the treatment of actinic keratosis are unknown.

12.3Pharmacokinetics 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 cm 2 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 (AUC 0-t ) and maximum concentration (C max ) 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 T max (time at which C max 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 AUC 0-t and C max 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 cm 2 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 (AUC 0-t ) and maximum concentration (C max ) 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 T max (time at which C max 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 C max of PpIX was 0.67 ± 0.78 ng/mL (n=13) with a median T max of 4 hours. The baseline corrected PpIX concentrations in 14 of 15 subjects were < 1 ng/mL.

🔬 Clinical Studies ~2 min read ▾

14. CLINICAL STUDIES 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/cm 2 . 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/cm 2 .

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. Table 2: Complete Clearance 12 Weeks After the Last Narrow Spectrum PDT in Subjects with Actinic Keratoses in Trials 1, 2 and 3 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.

🧪 Nonclinical Toxicology 144 words ▾

13. NONCLINICAL TOXICOLOGY

13.1Carcinogenesis, 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.

Medicaid utilization & spend

📍 This exact package only: Medicaid data is reported per full 11-digit NDC — labeler, product and pack size — so every number here is for this package alone, not the drug overall. Other pack sizes report separately.
💊 Pharmacy benefit only: These are Medicaid outpatient pharmacy claims, billed by NDC. They exclude the medical benefit — clinic- or hospital-administered drugs billed under HCPCS J-codes — so drugs used mostly that way (e.g. Avastin, Lucentis, Keytruda) can look low or missing here. That’s expected, not an error.
📅 Q1 2025 – Q1 2026 · 5 quarters of data
ⓘ The newest quarter is usually incomplete when first published; states restate recent quarters in later CMS releases, so the latest figures typically revise upward. State coverage-policy changes can also shift quarter-to-quarter totals.

💵 About the dollar figures: “reimbursed” is what Medicaid paid pharmacies before confidential manufacturer rebates, so the program’s real net cost is lower than these numbers. Fee-for-service and managed-care claims are combined unless split above. Source: CMS State Drug Utilization Data; per-100k rates use 2023 Census population estimates.

Medicaid utilization by pack size

Medicaid (SDUD) totals over the four most recent reported quarters for every package size of this drug — handy when a specific package (e.g. a starter/titration pack) carries little or no Medicaid volume on its own.

Questions about this listing

Why is there no price listed?
The pricing shown on our NDC pages comes from CMS NADAC, a voluntary survey of retail community pharmacy invoices. CMS does not publish a NADAC for every NDC — packages outside the retail survey (institutional and hospital products, bulk packages, discontinued items, and many OTC items) may never receive one. A missing price reflects the survey's scope, not this product's actual cost, and does not mean the product is free or unavailable.
Is the NDC printed on the package the same as the 11-digit billing NDC?
Yes, they identify this exact package in different formats. The form printed on the packaging and shown on DailyMed is the one the FDA registered. Insurance claims use a fixed 11-digit 5-4-2 format, so the short segment is padded with a leading zero and the dashes are dropped. The Identity section at the top of this page lists each form of this code.
Is this package still being marketed?
Yes, per the latest FDA NDC Directory data on this page: this package is listed as actively marketed, with no marketing end date reported by Biofrontera Inc.. Listing status can change — the directory data on this page refreshes weekly.
Does this product come in other package sizes?
Yes — the FDA directory lists 2 other package presentations of this same product, including 1 tube (70621-0101-30), 10 tubes (70621-0101-20). Each has its own NDC and its own page — see the package list near the top of this page.
Who lists this product with the FDA?
Biofrontera Inc. is the labeler of record for this NDC — the company under whose FDA-assigned code the package is listed. The labeler may be the manufacturer itself or a distributor marketing the product under its own code.
Do I need a prescription for this product?
This NDC is listed with FDA as a prescription product, so it is dispensed under a prescriber's order. Your pharmacist can tell you whether any over-the-counter forms of the same medication exist.
Does this product have a billing J-code?
Yes — this NDC cross-references HCPCS code J7345 for medical-claim billing (typically used when a product is administered in a clinical setting rather than dispensed at a retail pharmacy). See the Billing section on this page.
This page identifies an FDA-listed package (the NDC) and reports public regulatory and pricing data about the listing. It is reference information, not a medical recommendation — talk to your pharmacist or prescriber about your own medication.
Where does this data come from?
Listing facts (marketing category, packager status, marketing dates) from the FDA openFDA NDC Directory; label availability from DailyMed; pricing coverage from CMS NADAC; equivalence scope from the FDA Orange Book.
