Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • Women only
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Histologic diagnosis of epithelial ovarian carcinoma, primary peritoneal carcinoma, or fallopian tube carcinoma
  • Must be in second or third complete remission, have received chemotherapy (platinum-based and/or non-platinum-based) for recurrent disease, and have achieved a complete remission after their most recent chemotherapy regimen. Complete remission is defined as no symptoms suggestive of persistent cancer, computed tomography (CT) scan of the chest/abdomen/pelvis without evidence of ovarian cancer within 4 weeks of randomization, and normal CA-125 (measured within 2 weeks of randomization) following completion of prior chemotherapy. The study investigator should confirm the status of disease remission by CT scan before patient enrollment. If patient has lymphadenopathy by CT scan and the investigator thinks that it is unlikely due to ovarian cancer, this patient is considered eligible. If indicated, a confirmatory biopsy should be performed.
  • Patients must have completed their most recent cytotoxic chemotherapy regimen (platinum-based or non-platinum based) no less than 3 weeks and no more than 14 weeks prior to randomization.
  • Archival tissue must be available and requested.
  • Negative pregnancy test on Day 1 (first day the patient receives vismodegib or placebo).
  • For women of childbearing potential: Use of two effective methods of contraception, including one barrier method.

Who cannot join

  • Pregnancy or lactation.
  • Patients whose ovarian cancer is in first remission.
  • Patients must not have experienced more than two prior recurrences of disease.
  • Concurrent non-protocol-specified anti-tumor therapy, either approved or unapproved (eg, chemotherapy, hormonal therapy, other targeted therapy, radiation therapy, surgery, herbal therapy). Hormonal replacement therapies for treatment of postmenopausal symptoms do not exclude patients from this study.
  • Current, recent (within 4 weeks of Day 1), or planned participation in an experimental drug study while enrolled in this study.
  • History of other malignancies within 3 years of Day 1, except for tumors with a negligible risk for metastasis or death, such as adequately treated basal cell carcinoma (BCC) or squamous-cell carcinoma of the skin; ductal carcinoma in situ of the breast; or carcinoma in situ of the cervix.
Show all 9Show fewer
  • Uncontrolled medical illnesses such as infection requiring intravenous (IV) antibiotics.
  • Life expectancy < 12 weeks.
  • History of other disease, metabolic dysfunction, physical examination finding, or clinical laboratory finding giving reasonable suspicion of a disease or condition that contraindicates use of an investigational drug or that might affect interpretation of the results of the study or render the patient at high risk from treatment complications.

About this study

Official title: A Phase II, Multicenter, Randomized, Double-Blind, Placebo-Controlled Trial Evaluating the Efficacy and Safety of Vismodegib (GDC-0449) As Maintenance Therapy in Patients With Ovarian Cancer in a Second or Third Complete Remission

The study was a Phase II, randomized, placebo-controlled, double-blind, multicenter clinical trial of vismodegib (GDC-0449) in patients with ovarian cancer in a second or third complete remission. Patients were randomized in a 1:1 ratio to either vismodegib or placebo. Randomization was stratified based on whether their cancer was in a second or third complete remission.

Conditions
Ovarian Cancer
Being tested
Vismodegib 150 mg, Placebo to vismodegib

What participants receive

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

  • Vismodegib 150 mgDrug

    Also called GDC-0449

    Vismodegib 150 mg was provided in hard gelatin capsules.

  • Placebo to vismodegibDrug

    Placebo to vismodegib consisted of the excipients for vismodegib without the active molecule in hard gelatin capsules matching the active drug product in color and size.

What is being measured

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

  1. Progression-free Survival (PFS)

    PFS was defined as the time between randomization and disease progression, as confirmed by radiography, or death for any reason. Since patients were in remission at the start of the study, they had no evidence of the presence of tumors. Disease progression was defined as radiographic evidence of a tumor. Tumor assessments by computed tomography (CT) of the chest, abdomen, and pelvis were performed at screening and every 8 weeks during the study.

    Measured: From randomization date through the data cut-off date of May 15, 2010, up to 100 weeks

Secondary outcomes (2)
  1. Progression-free Survival (PFS) in Patients With Versus Without Hedgehog Antigen Tumor Expression

    Hedgehog antigen expression was measured with immunohistochemical methods in tumor tissue taken from each patient prior to enrollment in the study. The percentage of cells with (> 0%) and without (0%) Hedgehog antigen expression was measured microscopically. PFS was defined as the time between randomization and disease progression, as confirmed by radiography, or death for any reason. Tumor assessments by computed tomography (CT) of the chest, abdomen, and pelvis were performed at screening and every 8 weeks during the study.

    Measured: From randomization date through the data cut-off date of May 15, 2010, up to 100 weeks

  2. Overall Survival

    Overall survival was defined as the time from randomization until death by any cause.

    Measured: From randomization date through the data cut-off date of May 15, 2010, up to 100 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Vismodegib 150 mg in people with Ovarian Cancer, run by Genentech, Inc..

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 9 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 8 Jun 2017. Status can change between updates, so confirm with the study contact before making plans.

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 26 Apr 2012). 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?

Progression-free Survival (PFS) (time frame: From randomization date through the data cut-off date of May 15, 2010, up to 100 weeks). 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 8 Jun 2017.
