Phase 3b Study of Metvix NDL-PDT Versus Metvix c-PDT in Subjects With Actinic Keratoses (COMET2)

February 16, 2021 updated by: Galderma R&D

Multi-centre, Randomized, Investigator-blind, Intra-individual Active and Vehicle-controlled Study, Comparing Metvix Natural Daylight Photodynamic Therapy Versus Metvix Conventional Photodynamic Therapy in Subjects With Actinic Keratosis

This study was to be conducted as a multi-centre, randomized, investigator-blinded, active and vehicle-controlled, intra-individual (split-face/scalp) non-inferiority (regarding efficacy) and superiority (regarding pain) study.

The primary purpose of this study is to demonstrate the non-inferiority of NDL-PDT compared to c-PDT in terms of lesion complete response rate.

Study Overview

Status

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.
Interventional

Enrollment (Actual)

Enrollment

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Clinical diagnosis of mild (Grade 1) and/or moderate (Grade 2) AKs on the face or the scalp on treated areas
  • Subject with two symmetrical treated areas half scalps or two half faces excluding ears, chin, bridge of the nose, eyelids and lips inside the vermillion border): no more than a twofold difference in terms of total number of lesions between the two TAs

Exclusion Criteria:

  • Subject with clinical diagnosis of at least one severe (Grade 3) AK on treated areas
  • Subject with pigmented AK on the treated areas

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
Percentage (%) Change From Baseline in Total Lesion Complete Response at Week 12 in Group 1
Time Frame: Baseline, Week 12
The lesion complete response rate was defined as the percentage of pre-existing and treated lesions at Baseline that were assessed as clear (complete disappearance of the lesion, visually and by palpation) at Week 12. New lesions or the lesions in non-complete response were not not considered in the lesion response assessment. This outcome measure was analyzed as an intra-individual comparison between Metvix NDL-PDT on one side of the face/scalp and Metvix vehicle cream (placebo) c-PDT on the contralateral side (Group I).
