About this study

Official title: A Pilot Trial of GI-4000 Plus Bevacizumab and Either FOLFOX or FOLFIRI in Patients With Ras Mutant Positive Metastatic Colorectal Cancer, Either Newly Diagnosed or Previously Treated.

The purpose of this study is to test the safety of GI-4000 and see what effects (good and bad) it has against cancer over time. This study is also being done to measure the immune response to GI-4000. Study drug will be given in addition to a standard of care which is a standard therapy given to patients with your type of cancer (colon).

Read the detailed description

Subject visits will occur 1-4 weeks prior to initiation of GI-4000, then

  • In newly diagnosed (Group A) patients, at every FOLFOX/FOLFIRI plus bevacizumab visit, bevacizumab and GI-4000 dosing visit, GI-4000 dosing visit and then quarterly after completion of therapy
  • In patients with stable disease who have completed a first line therapy with an oxaliplatin or irinotecan plus fluoropyrimidine and bevacizumab containing regimen (Group B), at every bevacizumab and GI-4000 dosing visit, GI-4000 dosing visit and then quarterly after completion of therapy

Group A patients (N=26) will be enrolled into the study prior to the initiation of first line therapy with bevacizumab plus either FOLFOX (N=13) or FOLFIRI (N=13)

  • Subjects will receive 1 40 yeast units (YU) dose of GI-4000 prior to initiation of FOLFOX or FOLFIRI plus bevacizumab, then intercycle doses of GI-4000 will be given 7 days after each cycle while first line therapy is given (up to 8 cycles)
  • After completion of first line therapy, subjects will enter the maintenance phase in which bevacizumab and GI-4000 will be given concurrently every 2 weeks for as long as therapy can be tolerated or until progression
  • If a subject discontinues bevacizumab therapy due to intolerance, the subject will continue GI-4000 every 2 weeks until progression, intolerance or withdrawal from the study

Group B patients (N=26) with stable disease who have completed a first line therapy with an oxaliplatin or irinotecan plus fluoropyrimidine and bevacizumab containing regimen ) will enter the trial prior to receiving therapy with bevacizumab

  • Subjects will receive 40 yeast unit (YU) GI-4000 concurrently with each bevacizumab dose for as long as therapy can be tolerated or until progression
  • If a subject discontinues bevacizumab therapy due to intolerance, the subject will continue GI-4000 every 2 weeks until progression, intolerance or withdrawal from the study

What is being measured

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

  1. Number of Participants Alive and Free of Progression at 4 Months (Patients Who Have Undergone Prior Therapy) and 10 Months (Untreated Patients)

    Clinical benefit rate is defined as the proportion of patients alive and free of progression at 4 Months (Patients Who Have Undergone Prior Therapy) and 10 Months (Untreated Patients), assessed from first treatment with GI-4000. Progression is defined as CR (complete response) = disappearance of all target lesions; PR (partial response) = 30% decrease in the sum of the longest diameter of the target lesions; PD (progressive disease) = 20% increase in the sum of the longest diameter of the target lesions; or SD (stable disease) = small changes that do not meet the above criteria.

    Measured: 4 Months for patients who had undergone prior 1st-line therapy, and 10 months for previously untreated patients

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing chemotherapy and GI-4000 and GI-4000 in people with Colon Cancer, run by Georgetown University 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 9 inclusion and 20 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: stopped early, as of the sponsor's last update on 15 Aug 2016. 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?

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 15 Aug 2016). 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?

Number of Participants Alive and Free of Progression at 4 Months (Patients Who Have Undergone Prior Therapy) and 10 Months (Untreated Patients) (time frame: 4 Months for patients who had undergone prior 1st-line therapy, and 10 months for previously untreated patients). 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 15 Aug 2016.
