Topical Remetinostat in Treating Patient With Cutaneous Basal Cell Cancer

May 13, 2021 updated by: Kavita Sarin

A Phase 2 Open-Label, Single-Arm Trial of the Efficacy of Topical Remetinostat on Basal Cell Carcinoma in Patients

This phase 2 trial studies how well remetinostat works in treating patients with skin basal cell cancer. Remetinostat may slow the growth of basal cell cancer cells.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access 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.

Detailed Description

PRIMARY OBJECTIVES:

I. Overall response rate of basal cell carcinoma (BCC) in subjects at 6 weeks.

SECONDARY OBJECTIVES:

I. Suppression of GLI1 (glioma-associated oncogene) expression in treated BCCs as compared with baseline.

II. Safety assessment of Remetinostat after 6 weeks of topical treatment.

OUTLINE:

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.

Eligibility Criteria

Eligibility Criteria

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)

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
Overall Response Rate
Time Frame: At 6 weeks

Overall response is defined as achieving either a complete response (CR) or a partial response (PR). Response is based on the Response Evaluation Criteria in Solid Tumors (RECIST), as follows.

  • CR = tumor lesion becomes undetectable
  • PR = ≥30% decrease in total tumor diameter
  • Overall response (OR) = CR+PR
  • Stable Disease (SD) = decrease in total tumor diameter is >0% and <30%
  • Progressive Disease (PD) = increase in total tumor diameter Exact binomial 90% confidence intervals (90%) will be computed for OR. The data are reported accord to the per protocol analysis, ie, including lesions for subjects who were <70% compliant with drug treatment. For subjects who were compliant but dropped out, data from their last study visit will be used if they contribute a biopsy. The analysis population will include the participants who have provided pre-treatment and post-treatment biopsies. The outcome is reported as the percent of tumor lesions that achieve OR, with 90% CI.
At 6 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Number of Participants With a Decrease in Expression of the Hedgehog Biomarker Gene GLI1
Time Frame: 6 weeks
The effect of topical remetinostat gel 1% on decreasing expression of Hedgehog biomarker gene GLI1 was determined using the RNeasy Fibrous Tissue Mini Kit (Qiagen, Valencia, CA), a polymerase chain reaction (PCR) test kit. The levels observed at baseline and after 6 weeks treatment were obtained. The outcome is reported as the number of subjects for whom a decrease in expression of the Hedgehog biomarker gene GLI1 was observed, a number without dispersion.
6 weeks
Adverse Events Contributing to Treatment Discontinuation or Interruption
Time Frame: 6 weeks
Adverse events (AEs) contributing to treatment discontinuation or interruption are reported as the number of such events, a number without dispersion.
6 weeks
Participants Who Discontinued Treatment or Had Treatment Interruption
Time Frame: 6 weeks
The number of participants who discontinued treatment or experienced treatment interruption within the first 6 weeks of treatment are reported as the number of such participants, a number without dispersion.
