Clinical Study on 5-aminolevulinic Acid Hydrochloride (5-ALA) for Fluorescence-guided Resection of Malignant Gliomas

May 20, 2016 updated by: medac GmbH

Clinical Phase I/II Study on 5-aminolevulinic Acid Hydrochloride (5-ALA) for Fluorescence-guided Resection of Malignant Gliomas

This study is planned to detect a dose-efficacy relationship between the chosen dose levels of MC506/1 and the extent and quality of fluorescence in the tumour core in patients with newly diagnosed malignant glioma.

Study Overview

Status

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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.

  • Phase 1

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

18 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

N/A

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Radiological suspicion of a malignant glioma with distinct ring- or garland shaped, contrast agent-enhancing tumour structures and a core area of reduced intensity in the MRI (tumour necrosis)
  • Indication for surgical tumour resection
  • First operation of the tumour, no other tumour-specific pre-treatment
  • Karnofsky Performance Scale 70%
  • Patient's written informed consent
  • Age 18-75 years

Exclusion Criteria:

  • Porphyria, hypersensitivity to porphyrins

  • Renal insufficiency:

    • Creatinine > 2.0 mg/dl

  • Hepatic insufficiency:

    • Bilirubin > 3 mg/dl
    • Quick test < 60 %
    • GT > 100 U/I
  • Other known malignancy (except basaliomas)

Women:

  • Existing/planned pregnancy (to be checked by a pregnancy test if of child-bearing age)/lactation or inadequate contraception (hormone cycle regulation pill or condom)

Men:

  • Inadequate contraception (condom)
  • Dementia or mental condition making it impossible to understand the therapy and therefore prohibiting written consent
  • Simultaneous participation or participation in another clinical trial in the preceding 30 days

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
Detection of a dose-efficacy relationship between the dose levels and the extent and quality of fluorescence in the tumour core (of newly diagnosed malignant glioma).
Time Frame: Within 3 hours
After completion of resection, global fluorescence extent in the tumour core will be assessed by the first and second surgeon. It will be estimated whether approx. 0/3, 1/3, 2/3 or 3/3 of the tumour core is identified using standard white operation light were fluorescent (irrespective of fluorescence quality). The global quality of Gliolan induced tissue fluorescence within the tumour core will be recorded as being strong, weak or missing. As an objective control of the subjective assessment of the fluorescent quality, selected areas will be measured spectrometrically.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
February 1, 2000

Primary Completion (Actual)

Primary Completion

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.
