Pharmacology

Indication

As a topical gel, aminolevulinic acid (ALA) is indicated for lesion-directed and field-directed treatment of actinic keratoses (AKs) of mild-to-moderate severity on the face and scalp in combination with photodynamic therapy (PDT) using BF-RhodoLED® lamp, a narrowband, red light illumination source.5 As a topical solution, ALA can also be used for the same indication mentioned previously in addition to AKs of the upper extremities, but in conjunction with blue light illumination using the BLU-U Blue Light Photodynamic Therapy Illuminator.6 Finally, ALA is also available as an oral solution to be used as an adjunct for the visualization of glioma during surgery.7

Pharmacodynamics

The metabolism of aminolevulinic acid (ALA) is the first step in the biochemical pathway resulting in heme synthesis. Aminolevulinic acid is not a photosensitizer, but rather a metabolic precursor of protoporphyrin IX (PpIX), which is a photosensitizer. The synthesis of ALA is normally tightly controlled by feedback inhibition of the enzyme, ALA synthetase, presumably by intracellular heme levels. ALA, when provided to the cell, bypasses this control point and results in the accumulation of PpIX, which is converted into heme by ferrochelatase through the addition of iron to the PpIX nucleus.

Mechanism of action

According to the presumed mechanism of action, photosensitization following application of aminolevulinic acid (ALA) topical solution occurs through the metabolic conversion of ALA to protoporphyrin IX (PpIX), which accumulates in the skin to which aminolevulinic acid has been applied. When exposed to light of appropriate wavelength and energy, the accumulated PpIX produces a photodynamic reaction, a cytotoxic process dependent upon the simultaneous presence of light and oxygen. The absorption of light results in an excited state of the porphyrin molecule, and subsequent spin transfer from PpIX to molecular oxygen generates singlet oxygen, which can further react to form superoxide and hydroxyl radicals. Photosensitization of actinic (solar) keratosis lesions using aminolevulinic acid, plus illumination with the BLU-UTM Blue Light Photodynamic Therapy Illuminator (BLU-U), is the basis for aminolevulinic acid photodynamic therapy (PDT).

Topical gel

Pharmacokinetics (PK) of aminolevulinic acid (ALA) and PpIX was evaluated in a trial of 12 adult subjects with mild to moderate AK with at least 10 AK lesions on the face or forehead. A single dose of one entire tube of ALA (2 grams) was applied under occlusion for 3 hours followed by photodynamic therapy (PDT) to a total area of 20 cm2. The mean ± SD baseline plasma ALA and PpIX concentrations were 20.16 ± 16.53 ng/mL and 3.27 ± 2.40 ng/mL, respectively. In most subjects, an up to 2.5-fold increase of ALA plasma concentrations was observed during the first 3 hours after ALA application. The mean ± SD area under the concentration time curve (AUC0-t) and maximum concentration (Cmax) for baseline corrected ALA (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.

Topical solution

Two human pharmacokinetic (PK) studies were conducted in subjects with minimally to moderately thick actinic keratoses on the upper extremities, having at least 6 lesions on one upper extremity and at least 12 lesions on the other upper extremity. A single dose comprising of two topical applications of ALA topical solution (each containing 354 mg ALA HCl) were directly applied to the lesions and occluded for 3 hours prior to light treatment.

The first PK study was conducted in 29 subjects and PK parameters of ALA were assessed. The baseline corrected mean ± SD of the maximum concentration (Cmax) of ALA was 249.9 ± 694.5 ng/mL and the median Tmax was 2 hours post dose. The mean ± SD exposure to ALA, as expressed by area under the concentration time curve (AUCt) was 669.9 ± 1610 ng·hr/mL. The mean ± SD elimination half-life (t1/2) of ALA was 5.7 ± 3.9 hours.

A second PK study was conducted in 14 subjects and PK parameters of ALA and PpIX were measured. The baseline corrected PpIX concentrations were negative in at least 50% of samples in 50% (7/14) subjects and AUC could not be estimated reliably. The baseline-corrected mean ± SD of Cmax for ALA and PpIX was 95.6 ± 120.6 ng/mL and 0.95 ± 0.71 ng/mL, respectively. The median Tmax of ALA and PpIX was 2 hours post dose and 12 hours post dose, respectively. The mean AUCt of ALA was 261.1 ± 229.3 ng·hr/mL. The mean ± SD t1/2 of ALA was 8.5 ± 6.7 hours.

Oral solution

In 12 healthy subjects, the absolute bioavailability of ALA following the recommended dose of ALA 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).

Volume of distribution

In healthy volunteers, the administration of aminolevulinic acid resulted in a volume of distribution of 9.3 ± 2.8 L intravenously and 14.5 ± 2.5 orally.[11961050]

Protein binding

In in vitro experiments using aminolevulinic acid (ALA) concentrations up to approximately 25% of the maximal concentration that occurs in plasma following the recommended dose of ALA solution, the mean protein binding of ALA was 12%.7

Metabolism

Exogenous aminolevulinic acid (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.7

Route of elimination

In 12 healthy subjects, excretion of parent aminolevulinic acid (ALA) in urine in the 12 hours following administration of the recommended dose of ALA solution was 34 + 8% (mean + std dev) with a range of 27% to 57%.7

Half-life

The mean ± SD elimination half-life (t1/2) of aminolevulinic acid was 5.7 ± 3.9 hours for the topical solution formulation and the mean half-life was 0.9 ± 1.2 hours for the oral solution formulation.6,7 In another pharmacokinetic studies with 6 healthy volunteers using a 128 mg dose, the mean half-life was 0.70 ± 0.18 h after the oral dose and 0.83 ± 0.05 h after the intravenous dose.8

Toxicity

There are no available human data on aminolevulinic acid (ALA) 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.7

No carcinogenicity testing has been carried out using ALA. No evidence of mutagenic effects was seen in four studies conducted with ALA to evaluate this potential. In the Salmonella-Escherichia coli/mammalian microsome reverse mutation assay (Ames mutagenicity assay), no increases in the number of revertants were observed with any of the tester strains. In the Salmonella-Escherichia coli/mammalian microsome reverse mutation assay in the presence of solar light radiation (Ames mutagenicity assay with light), ALA did not cause an increase in the number of revertants per plate of any of the tester strains in the presence or absence of simulated solar light. In the L5178Y TK± mouse lymphoma forward mutation assay, ALA was evaluated as negative with and without metabolic activation under the study conditions. PpIX formation was not demonstrated in any of these in vitro studies. In the in vivo mouse micronucleus assay, ALA was considered negative under the study exposure conditions. In contrast, at least one report in the literature has noted genotoxic effects in cultured rat hepatocytes after ALA exposure with PpIX formation. Other studies have documented oxidative DNA damage in vivo and in vitro as a result of ALA exposure.6

No assessment of effects of ALA HCl on fertility has been performed in laboratory animals. It is unknown what effects systemic exposure to ALA HCl might have on fertility or reproductive function.6
