About this study

Official title: A Long-term, Single-arm, Open-label Trial of NPC-12G (Topical Formulation of Sirolimus) to Angiofibroma and Other Skin Lesions in Patients With Tuberous Sclerosis Complex

The purpose of this trial is to evaluate the safety and efficacy of long-term treatment with NPC-12G gel (0.2% sirolimus gel) to angiofibroma and other skin lesions in patients with tuberous sclerosis complex in the open-label trial.

Read the detailed description

Tuberous Sclerosis Complex (TSC) is an autosomal dominant hereditary disease that causes benign tumors on the almost whole body (including skin, brain, kidney, lung and heart), behavior disorder as autism, mental retardation and neurologic symptom as epilepsy. Angiofibroma is a TSC-specific facial skin lesion, and hamartoma caused by increase of the component of skin connective tissues and blood vessels. Other skin lesions due to TSC are white macule (hypomelanotic macule), plaque, shagreen patch and ungual fibromas. Current therapeutic methods for angiofibroma are laser and surgical treatments, but there are problems as many relapses, deficiency of evidence, change of pigment, scar and risk of infection.

This is a multicenter and open-label trial. The trial consists of two phase. In the first trial phase for 52 weeks, the efficacy as well as the safety is evaluated. For the second trial phase the trial will be continued until the date of approval of NDA for NPC-12G. The safety is evaluated during the second trial phase, but not the efficacy. Patients who meet all entry criteria for the trial apply 0.2% NPC-12G gel twice a day. Patients will visit at 4 to 5-week intervals for the first 6 months of the first trial phase, and then 3 months intervals thereafter.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The discontinuation rate due to adverse events

    The first discontinuation in each patient due to adverse events is assessed.Completion of week 26 and 52 are cut-off points for interim-analyses by Kaplan-Meier method

    Measured: 52 weeks and longer

Secondary outcomes (14)
  1. Adverse events and adverse events related to the test drug

    The number of discontinuation/ resume due to adverse events are evaluated. Completion of week 26 and 52 are cut-off points for interim-analyses

    Measured: 52 weeks and longer

  2. Adverse events related to the test drug leading to the discontinuation permanently

    The incidence of adverse events are evaluated. Completion of week 26 and 52 are cut-off points for interim-analyses

    Measured: 52 weeks and longer

  3. Serious adverse events and serious adverse events related to the test drug

    The incidence of serious adverse events are evaluated. Completion of week 26 and 52 are cut-off points for interim-analyses

    Measured: 52 weeks and longer

  4. Adverse events and adverse events related to the test drug leading to modification of dosage and administration

    The incidence of adverse events are evaluated. Completion of week 26 and 52 are cut-off points for interim-analyses

    Measured: 52 weeks and longer

  5. Significant adverse events and significant adverse events related to the test drug

    The incidence of significant adverse events such as local irritation are evaluated. Completion of week 26 and 52 are cut-off points for interim-analyses

    Measured: 52 weeks and longer

  6. Laboratory tests, vital signs

    Completion of week 26 and 52 are cut-off points for interim-analyses

    Measured: Baseline and every 3 months for laboratory tests, every scheduled visit for vital sign]

  7. Blood level of sirolimus

    Whole blood level of sirolimus are measured any day time at baseline and every 3 months visit

    Measured: Baseline and every 3 months only for the first trial phase

  8. Improvements in angiofibroma

    Improvements comparing with baseline is assessed using photograph by the investigator and the central photo-judgement committee. Completion of week 26 is a cut-off point for interim-analysis.

    Measured: Week 4, 8, 12, 26, 39 and 52

  9. Improvements in sizes of angiofibroma

    Improvements comparing with baseline is assessed using photograph by the investigator and the central photo-judgement committee. Completion of week 26 is a cut-off point for interim-analysis.

    Measured: Week 4, 8, 12, 26, 39 and 52

  10. Improvements in redness of angiofibroma

    Improvements comparing with baseline is assessed using photograph by the investigator and the central photo-judgement committee. Completion of week 26 is a cut-off point for interim-analysis.

    Measured: Week 4, 8, 12, 26, 39 and 52

  11. Improvements in white macule and plaque upper neck

    Improvements comparing with baseline is assessed using photograph by the investigator and the central photo-judgement committee. Completion of week 26 is a cut-off point for interim-analysis.

    Measured: Week 4, 8, 12, 26, 39 and 52

  12. The rate of patients evaluated ''improvement'' or more (improvement rate) in above the efficacy measures.

    Completion of week 26 is a cut-off point for interim-analysis.

    Measured: Week 4, 8, 12, 26, 39 and 52

  13. Change in total score of DLQI and CDLQI from baseline

    DLQI for subjects 16 years old and greater, or CDLQI for children of less than 16 years old is assessed by patients. Completion of week 26 is a cut-off point for interim-analysis.

    Measured: Week 4, 8, 12, 26, 39 and 52

  14. Degree of patient's satisfaction

    Patient's satisfaction is assessed by patient. Completion of week 26 is a cut-off point for interim-analysis.

    Measured: Week 12, 26, 39 and 52

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing NPC-12G gel in people with Tuberous Sclerosis and Angiofibroma, run by Nobelpharma at 1 site in Japan.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 20 Feb 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Japan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The discontinuation rate due to adverse events (time frame: 52 weeks and longer). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02634931, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Feb 2019.
