About this study

Official title: Study of the Relationship Between the Pharmacokinetics of Vismodegib and Safety Data: a Pilot Study to Therapeutic Optimization in Patients With Basal Cell Carcinoma - OPTIVISMO-1

Vismodegib (ERIVEDGE®) at the standard dose of 150 mg/day orally is indicated for the treatment of advanced Basal Cell Carcinoma (BCC) and is associated with many adverse effects. Cramps, alopecia, dysgeusia, weight loss and others observed in clinical practice, compromize compliance and often lead to treatment discontinuation. Currently, it is the only drug available in this indication. Our main objective is to assess the relationship between plasma concentrations of vismodegib, and the occurrence of adverse effects within 6 months of inclusion in the study.

Read the detailed description

In patients treated with the Hedgehog (Hh) signaling pathway inhibitor, vismodegib, for Basal Cell Carcinoma (BCC), intolerance to this drug is a cause of non-compliance to treatment and often requires therapy discontinuation in spite of its potent anticarcinomic action. Indeed, vismodegib, at the standard dose of 150 mg/day, leads to many heavy side effects often 1 month after therapy initiation. The major side effects are daily or multiple daily cramps (associated with hypometabolism) in 60% of patients, dysgeusia, ageusia and alopecia (related to stem cells), and tiredness. Currently, there is no recommendation for dose adjustment against the occurrence of these adverse effects, so that clinicians propose temporary or definitive therapeutic discontinuation for around 30% of patients. The management of these therapeutic pauses is a challenge for clinicians, as no data are available on their impact on treatment long-term response. We hypothesize that vismodegib side effects are related to high plasma concentrations of drug in many patients. To date, there is no data from phase 3 study, sparse pharmacokinetic data emanating from Phase 1 and 2 studies in various solid tumors.

Patients included are treated with vismodegib (Hedgehog (Hh) pathway inhibitor) for symptomatic metastatic BCC, or for advanced BCC when surgery and radiotherapy are not appropriate. Included patients are new patients initiating a treatment with vismodegib or patients already on vismodegib. The study of the relationship between plasma concentrations of vismodegib and tolerance, requires at each monthly follow-up visits, monitoring of: concentrations of free (unbound to the α1-GPA) and total (bound and unbound) forms of vismodegib, α1-GPA plasma concentrations, patient's status, data on safety and efficacy, and clinical and biological data (covariates that may modulate the vismodegib pharmacokinetics resulting in increased plasma concentrations). Patients will be followed for 6 months.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Treatment with vismodegibDrug

    Vismodegib 150 mg capsules is administered daily with or without food until disease progression or unacceptable toxicity. Patients are followed in the dermatologic unit of Bordeaux University Hospital (Saint André Hospital) every month. At each consultation, clinical and biological datas, and two blood samples are collected just before taking the drug. One sample is for vismodegib quantification (pharmacokinetic protocol), and the other for the determination of alpha-1 glycoprotein acid level

What is being measured

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

  1. Serious side effects (grade 2 or more) during the clinical response follow-up to vismodegib

    Patients already on vismodegib will be monitored at inclusion and for 6 months (M0, M1, M2, M3, M4, M5). New patients will be monitored from the end of the first month after inclusion and during 6 months (M1, M2, M3, M4, M5, M6)

    Measured: Occurrence from inclusion to 6 months visit

Secondary outcomes (2)
  1. Relationship between the plasma concentrations of free and/or total vismodegib, and covariates

    Measured: From inclusion to 6 months visit

  2. Clinical response to vismodegib in term of efficacy

    Classification into 4 categories: progression, stabilité, partial response and complete response according to RECIST criteria

    Measured: at least at each visit, from inclusion to 6 months visit

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Treatment with vismodegib in people with Metastatic Basal Cell Carcinoma and Locally Advanced Basal Cell Carcinoma, run by University Hospital, Bordeaux at 1 site in France.

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 5 inclusion and 8 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 19 May 2026. 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 France. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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?

Serious side effects (grade 2 or more) during the clinical response follow-up to vismodegib (time frame: Occurrence from inclusion to 6 months visit). 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 19 May 2026.
