About this study

Official title: A Double-blind, Randomized, Vehicle-controlled Proof of Concept (PoC) Study to Evaluate the Safety, Local Tolerability, Pharmacokinetics and Pharmacodynamics of Multiple Topical Administrations of LDE225 (a Specific Smoothened Inhibitor) on Skin Basal Cell Carcinomas in Gorlin Syndrome Patients Followed by an Open Label, Randomized Expansion Group to Test Two Different Strengths of an Improved LDE225 Formulation for Extended Treatment Durations

Part I was a double-blind, randomized, vehicle-controlled Proof of Concept (PoC) study to evaluate the safety, local tolerability, pharmacokinetics and pharmacodynamics of multiple topical administrations of LDE225 (a specific Smoothened inhibitor) on skin basal cell carcinomas in Gorlin's syndrome patients.

Following a 21-day screening period, patients were exposed to multiple doses of topically applied LDE225 twice daily for 4 weeks in a double-blind manner. The patients returned weekly for visits where each BCC was clinically evaluated and digital photographs taken. Local safety and tolerability was also assessed. After the last application of treatment, biopsies were taken from treated (both vehicle and LDE225) BCCs (three per patient) for histology, biomarker evaluation and for pharmacokinetics (skin exposure). In addition, a biopsy from LDE225-treated uninvolved perilesional skin was taken for pharmacokinetic evaluation. In total, 4 biopsies were taken: 2 for histology and biomarker and 2 for PK.

Part II of this study consisted of a 21-day screening period, a baseline period (directly before commencing the treatment period) and a treatment period of 6 or 9 weeks, depending on randomization. A clinical assessment was performed on site on the last treatment day and if a full clinical response had been observed, approximately 3 weeks after the last treatment an excision of the BCC(s) would have been performed. The study completion visit occurred either 1 week after the excision (when this visit was planned) or 1 week after the last treatment. For a subset of patients, skin biopsies were collected on the last treatment day and an excision of a BCC was also performed at that same visit.

What is being measured

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

  1. Percentage of BCCs With Complete and at Least Partial Clinical Clearance

    Clinical response parameters were defined as (i) complete response (i.e., there is no longer any visible evidence of a lesion consistent with BCC at this site), (ii) partial response (i.e., although a BCC still remains at this site, it has demonstrated a visible decrease in size compared with baseline), and (iii) no response / worsening (i.e., the BCC has not demonstrated any visible decrease in size compared with baseline).

    Measured: 4 weeks, 6 weeks, 9 weeks

  2. Number of Participants With at Least Partial Clinical Clearance (Part I)

    Clinical response parameters were defined as (i) complete response (i.e., there is no longer any visible evidence of a lesion consistent with BCC at this site), (ii) partial response (i.e., although a BCC still remains at this site, it has demonstrated a visible decrease in size compared with baseline), and (iii) no response / worsening (i.e., the BCC has not demonstrated any visible decrease in size compared with baseline).

    Measured: day 8, day 15, day 22, day 29

Secondary outcomes (4)
  1. Change From Baseline in Tumor Measurements (Part I)

    Measurement of the tumor size, volume and color by standardized digital photography, using dermatoscopic, macroscopic and 3D images of the BCCs was done by participant where if a participant had more than one tumor, for each of these tumors, the change from baseline was calculated (% change). From these values, the mean was calculated to get only one result per participant. Then for all the participants (n=8 both for LDE and vehicle), the mean was calculated. Photographic analysis was conducted by QuantifiCare. The volume of a lesion was measured with a special device, the "3D LIFEVIZ Micro system", which uses a lens splitter to produce two images of the skin surface, captured at the same time, with viewing angle differences close to human vision. A stereovision algorithm is then applied to reconstruct and quantitatively analyze the skin surface in 3D. A negative change from baseline indicates improvement.

    Measured: 4 weeks

  2. Change From Baseline in Tumor Measurements (Part II)

    Measurement of the tumor size, volume and color by standardized digital photography, using dermatoscopic, macroscopic and 3D images of the BCCs was done by participant where if a participant had more than one tumor, for each of these tumors, the change from baseline was calculated (% change). From these values, the mean was calculated to get only one result per participant. Then for all the participants (n=8 both for LDE and vehicle), the mean was calculated..

  3. Change From Baseline in Tumor Measurements (by Tumor) (Part I)

    Measurement of the tumor size, volume and color by standardized digital photography, using dermatoscopic, macroscopic and 3D images of the BCCs.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing LDE225 0.25% and LDE225 0.75% in people with Treatment for Basal Cell Carcinomas (BCCs) in Gorlin Syndrome Patients, run by Novartis Pharmaceuticals at 3 sites in 2 countries.

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 1 inclusion and 3 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 3 Nov 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in Austria, Switzerland. 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. Some participants in this study may receive a placebo. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

Yes. Results are posted in the registry (first posted 21 Sep 2015). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Percentage of BCCs With Complete and at Least Partial Clinical Clearance (time frame: 4 weeks, 6 weeks, 9 weeks). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 3 Nov 2015.
