Phase 2 Study Evaluating the Safety and Efficacy of Microneedle-mediated Delivery of Doxorubicin (D-MNA) in Patients With Nodular Basal Cell Carcinoma.

April 28, 2026 updated by: SkinJect, Inc.

A Randomized, Double-blind, Three-arm Phase 2 Study Evaluating Two Dose Levels of Microneedle-mediated Delivery of Doxorubicin Compared With a Device-only Control in Patients With Nodular Basal Cell Carcinoma.

This Phase 2 study evaluates the safety and efficacy of microneedle array (MNA) alone and in combination with two dose levels of doxorubicin (100µg and 200µg) in patients with nodular basal cell carcinoma. Efficacy is assessed using both clinical (visual) and histological endpoints, which together provide a comprehensive evaluation of lesion response.

Study Overview

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

A total of 90 subjects were enrolled and randomized in a 1:1:1 ratio to receive microneedle array (MNA) alone or Doxorubicin-MNA (D-MNA) at dose levels of 100µg or 200µg. Treatments were administered once weekly for three applications to a single target lesion. Following treatment, the target lesion was excised at a prespecified timepoint and assessed for clearance. The study was amended during conduct to increase the total sample size (from 60 to 90) and to extend the timing of excision from Day 29 to Day 57 to allow for an optimized evaluation for treatment response. Efficacy is evaluated using both clinical (visual) and histological assessments. These endpoints represent complementary dimensions of lesion response, with clinical clearance reflecting visible resolution and histological clearance providing pathological confirmation. Central pathological review was conducted for all excision specimens and where possible, baseline biopsy visits to confirm nodular BCC. This Phase 2 study is exploratory in nature, and efficacy is interpreted based on the totality of evidence across endpoints rather than a strictly hierarchical framework. Analyses are descriptive and not powered for formal hypothesis testing.

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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Key Exclusion Criteria:

  1. Pregnant, lactating, or planning to become pregnant.
  2. nBCC is located on the face, scalp, digits, mucosa, or skin that is scarred or previously treated with radiation.

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
Histological Clearance of Target Lesion
Time Frame: Day 29 or Day 57 following treatment, per protocol amendment.
Proportion of subjects with complete histological clearance of the Target Lesion at Visit 5/EV. Histological clearance represents pathological confirmation of treatment response and is interpreted in the context of overall clinical and histological outcomes.
Day 29 or Day 57 following treatment, per protocol amendment.

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
Clinical Clearance of Target Lesion
Time Frame: Day 29 or Day 57 following treatment, per protocol amendment.
Proportion of subjects achieving complete clinical (visual) clearance of the Target Lesion at Visit 5 / Excision Visit, reflecting visible resolution of disease following treatment.
