This phase I trial studies the side effects and best dose of photodynamic therapy using aminolevulinic acid in treating patients with oral leukoplakia. Photodynamic therapy uses a drug, such as aminolevulinic acid, that becomes active when it is exposed to a certain kind of light. When the drug is active, abnormal cells are killed. Photodynamic therapy using aminolevulinic acid may be effective against oral leukoplakia.
PRIMARY OBJECTIVES:
I. To determine the toxicity and feasibility of photodynamic therapy using pulsed laser therapy and oral aminolevulinic acid in treating patients with oral leukoplakia.
II. To define the dose-limiting toxicity and maximum tolerated dose of photodynamic therapy using pulsed laser therapy and oral aminolevulinic acid in these patients.
SECONDARY OBJECTIVES:
I. To assess the efficacy of photodynamic therapy using pulsed dye laser and oral aminolevulinic acid by examining clinical response at 1 and 3 months.
II. To determine quantitative histologic response at 3 months. III. To explore the association of response with specific molecular and biologic markers (i.e., DNA ploidy, proliferation using Ki-67, apoptosis using TUNEL, cyclin D1, and p53).
OUTLINE: This is a dose-escalation study of long pulsed dye laser light.
Patients receive aminolevulinic acid* orally (PO) 3-4 hours before undergoing photodynamic therapy using pulsed dye laser on day 1.
(Note: *Patients in cohort 1 and a latter cohort [to be determined during the course of the study] do not receive aminolevulinic acid before photodynamic therapy.)
Patients undergo biopsies of target lesions and clinically uninvolved mucosa 4-8 weeks before beginning therapy and then at 3 months for biomarker studies (DNA ploidy, p53, Ki-67, cyclin D1, and TUNEL assay). Blood is collected on days 1, 2, 14, 28, and 84 for toxicity assessment.
After completion of study treatment, patients are followed for up to 84 days.
Criteria:
No uncontrolled intercurrent illness including, but not limited to, any of the following:
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.
The diagnosis was confirmed by looking at a sample under a microscope: tissue from a biopsy or surgery (histology), or cells from a fluid or needle sample (cytology).
Your pathology report is the document that shows this.
A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.
Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.
A 0–100 scale of how well someone can carry out everyday activities. 100 is no complaints and no signs of illness; 70 is able to look after yourself but not to work or keep up normal activity; 50 is needing considerable help and frequent medical care.
Studies often ask for 60 or 70 and above. Your doctor gives the score.
The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.
The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).
Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.
The number of neutrophils, white blood cells that help fight infection, in a given amount of blood. Too few raises the risk of infection.
It is a count, not a percentage of the white cells. Limits are written in units that mean the same: ≥ 1.5 × 10⁹/L is ≥ 1,500 per mm³ (µL). Each lab has its own reference range.
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.
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.
A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.
Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.
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.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
Histologically or cytologically confirmed

Karnofsky performance status (KPS)
