About this study

Official title: A Phase IIa Open Label, Randomized Clinical Trial to Study the Safety and Efficacy of Vintafolide and the Combination of Vintafolide and Paclitaxel Compared to Paclitaxel in Subjects With Advanced Triple Negative Breast Cancer Using Etarfolatide (EC20) Subject Selection

The purpose of this study is to assess the efficacy and safety of vintafolide alone compared to vintafolide plus paclitaxel and paclitaxel alone in participants with with 100% positive folate receptor (FR) triple negative breast cancer (TNBC).

The primary hypothesis of this study is the vintafolide alone and/or vintafolide + paclitaxel will improve progression free survival (PFS) in participants with FR (100%) TNBC compared to paclitaxel alone.

Read the detailed description

During the screening stage, participants will be required to have a diagnostic computed tomography (CT) scan with etarfolatide (EC20) to identify target lesions and determine eligibility for treatment. After successful screening, during the treatment stage, participants will receive study drug (vintafolide, vintafolide + paclitaxel, or paclitaxel) for approximately four 28-day cycles.

Being tested
Vintafolide 2.5 mg, Paclitaxel 80 mg/m^2, Etarfolatide, Folic acid, Premedication for Paclitaxel
Medical subject headings
Breast Neoplasms

What participants receive

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

  • Vintafolide 2.5 mgDrug

    During treatment, participants receive IV vintafolide 2.5 mg.

  • Paclitaxel 80 mg/m^2Drug

    During treatment, participants receive IV paclitaxel 80 mg/m^2.

  • EtarfolatideDrug

    During screening and prior to screening CT scan, participants receive an IV injection of 0.1 mg etarfolatide radiolabeled with 20 to 25 milliCuries of technetium-99m.

  • Folic acidDrug

    During screening and prior to etarfolatide injection and screening CT scan, participants receive an IV injection of 0.5 mg folic acid.

  • Premedication for PaclitaxelDrug

    During treatment, participants receive dexamethasone 20 mg orally 12 to 6 hours prior to paclitaxel; OR promethazine 25 mg or 50 mg IV 30 to 60 minutes prior to paclitaxel; OR cimetidine 300 mg IV or ranitidine 50 mg IV 30 to 60 minutes prior to paclitaxel.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Vintafolide 2.5 mg, Paclitaxel 80 mg/m^2 and Etarfolatide in people with Breast Neoplasms, run by Endocyte.

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 9 inclusion and 19 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: withdrawn, as of the sponsor's last update on 19 Dec 2014. 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. 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?

The study was withdrawn before enrolling participants, so there are no results.

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: Up to 60 months). 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 Dec 2014.
