About this study

Official title: A Pharmacodynamic Study of Vismodegib in Men With Metastatic Castration-resistant Prostate Cancer (mCRPC) With Accessible Metastatic Lesions for Tumor Biopsy

This is a single-arm pharmacodynamic study with mandatory metastatic tumor biopsies in men with castration-resistant prostate cancer.

The trial will evaluate the effect of vismodegib on tumor tissue in men with metastatic CRPC by obtaining tumor biopsies at baseline and after 4 weeks of treatment with vismodegib.

Read the detailed description

The study will enroll 10 evaluable patients. Patients will receive a 30-day supply of 150 mg of vismodegib on day one of each cycle daily by mouth, beginning on Day 1, and continuously until one of the following occurs: Disease progression, intolerable toxicity most probably attributable to vismodegib or withdrawal from the study.

Tumor biopsies (nodal or visceral), skin biopsies, and CTCs will be obtained at baseline and after 4 weeks of treatment. PSA evaluations will be conducted every 4 weeks, imaging assessments (CT and Bone scan) will be conducted every 12 weeks and routine labs (blood counts and chemistry panel) will be conducted every 4 weeks.

The investigator's intent is to examine the fold change in GLI1 expression in each man following exposure to drug (comparing pre-treatment and on-treatment core biopsy samples). As secondary endpoints, the investigator will also explore clinical response (PSA responses, progression-free survival [PFS], radiographic responses), safety, and will examine changes from baseline in Gli2, PTCH1, and AKT1 mRNA levels by qRT-PCR, in situ GLI1 expression in tissue sections by mRNA in situ hybridization, and GLI1 expression in isolated circulating tumor cells (CTCs).

What is being measured

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

  1. The Proportion of mCRPC Patients Treated With Vismodegib Who Achieve a Pharmacodynamic (PD) Response in Tumor Biopsies

    The primary endpoint is the proportion of mCRPC patients treated with vismodegib who achieve a pharmacodynamic (PD) response in tumor biopsies, defined as both a decrease in GLI1 mRNA greater than 1.2 times the standard deviation (SD) of the baseline values and a ≥50% (≥2-fold) reduction in GLI1 messenger ribonucleic acid (mRNA) expression in metastatic tumor biopsies after 4 weeks of treatment when comparing post-treatment biopsy to pre-treatment biopsy in the same patient.

    Measured: Up to 1 year

Secondary outcomes (4)
  1. GLI1 Expression

    Suppression by vismodegib in tumor tissue of Hh-regulated transcripts and proteins was defined as the change from baseline in expression levels of GLI1 in situ tissue expression by mRNA in situ hybridization.

    Measured: Up to 1 Year

  2. Progression-free Survival (PFS)

    Progression-free survival (PFS) is defined by the Prostate Cancer Working Group 2 (PCWG2) criteria using RECIST 1.1 criteria for each patient. PFS is defined as the time of first dose (a) until prostate specific antigen (PSA) progression (by 25% increase in PSA from nadir) or death and (b) until any evidence of progression (by 25% increase in PSA from nadir, a new lesion on bone or CT scan, or physical examination) or death. PFS will be assigned to the earliest observed time.

    Measured: Up to 1 Year

  3. AKT1 Expression in Tumor Biopsies

    The tumor biopsies were evaluated for changes to Hh-regulated transcript, AKT1, between pre-treatment and post-treatment

    Measured: Up to 1 Year

  4. The Effect of Vismodegib on PSA Responses

    The effect of vismodegib on PSA responses will be assessed as the number of patients with participants with ≥50% PSA reductions at any time point during study

    Measured: Up to 1 Year

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing Vismodegib in people with Prostate Cancer, run by Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins at 1 site in United States.

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 22 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 20 Jul 2018. 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 United States. 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?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

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 20 Jul 2018). 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?

The Proportion of mCRPC Patients Treated With Vismodegib Who Achieve a Pharmacodynamic (PD) Response in Tumor Biopsies (time frame: Up to 1 year). 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 NCT02115828, 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 Jul 2018.
