Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a single-center, single-arm, open-label study to evaluate the efficacy and safety of topical Radion™-pdt for treatment of patients with oral verrucous hyperplasia (OVH) or oral erythroleukoplakia (OEL).

Total duration of the study will be up to 40 weeks (from screening throughout study until completion) as follows:

  • Screening (within 2 weeks before dosing)
  • Treatment period (up to 14 weeks)
  • Safety follow-up period (within 2 weeks after final treatment)
  • Follow-up period (final treatment plus 4 weeks, 8 weeks, 16 weeks and 24 weeks respectively) All enrolled patients will receive up to 8 treatments (once every two weeks) during a maximum of 14-week study treatment period. The treated lesion will be clinically evaluated and documented (clinical photograph) at each treatment visit.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

20 years and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Description

Inclusion Criteria:

  1. Patients aged ≥20 years old;

Besides, patients should have at least one lesion whose size should not exceed 4 cm in the greatest diameter and the distance between two lesions should not less than 1 cm.
  3. Patient who is willing and able to comply with study procedures and sign informed consent

Exclusion Criteria:

  1. Patients with history of hypersensitivity to any photosensitizer (including 5-aminolevulinic acid HCl or porphyrins), acute or chronic types of porphyria;
  2. Record of previous unsuccessful treatment with photodynamic therapy;
  3. Patients who have been diagnosed as having oral cancer or carcinoma in situ;
  4. Patients who have a history or evidence of a medical condition that would expose them to an undue risk of a significant adverse event during the course of the trial, including but not limited to hepatic, renal, respiratory, cardiovascular, endocrine, immune, neurological, hematological, gastrointestinal or psychiatric disease as determined by the clinical judgment of the investigator;
  5. Patients with impaired hepatic function (defined as AST and/or ALT > 2× the upper limit of normal values), and/or impaired renal function (defined as serum creatinine > 1.5 mg/dL);

  6. Female patient of childbearing potential who:

    • is lactating; or
    • has positive urine pregnancy test at visit -1; or
    • refuses to adopt reliable method of contraception during the study;
  7. Patient has received any other investigational agent within 28 days or 5 half-lives, whichever is longer, prior to the first photodynamic therapy;
  8. Patient has a history of illegal substance abuse, drug addiction or alcoholism within 24 weeks prior to the study.

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available.

EXPERIMENTAL: Single-Arm

The Radion™-pdt will be applied topically to the lesion. The Radion™-pdt applied dosage is about 0.1 mL/cm^2 and properly cover the entire lesion.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
The primary efficacy endpoints: the complete response rate is higher or equal to 70% of total
Time Frame: 2-week safety follow-up period after last treatment

The complete response rate at the end of treatment will be calculated by the proportion of complete response patients in total. The primary efficacy endpoints will be summarized by examining whether the complete response rate is higher or equal to 70% of total.

Complete response (CR): lack of detectable lesion confirmed by visual evaluation.
2-week safety follow-up period after last treatment

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
