About this study
Official title: Phase I/II Study of Multiple-Vaccine Therapy Using Epitope Peptide Restricted to HLA-A*0201 in Combination With Tegafur/Uracil/Folinate in Treating Patients With Refractory Colorectal Cancer
The purpose of this study is to evaluate the safety and time to progression of HLA-A*0201 restricted epitope peptides VEGFR1 and VEGFR2 emulsified with Montanide ISA 51 in combination with Tegafur/Uracil/Folinate chemotherapy.
Read the detailed description
VEGF receptor 1 and 2 are essential targets to tumor angiogenesis, and we identified that peptides derived from these receptors significantly induce the effective tumor specific CTL response in vitro and vivo. According to these findings, in this trial, we evaluate the safety, clinical and immunological response of those peptides. Patients will be vaccinated twice a week for 8 weeks. On each vaccination day, VEGFR1 peptide (1mg) and VEGFR2 peptide (1mg) mixed with Montanide ISA 51 will be administered by subcutaneous injection. The patients will also receive oral chemotherapy (Tegafur/Uracil/Folinate) simultaneously. Repeated cycles of the vaccine and the chemotherapy will be administered until patients develop progressive disease or unacceptable toxicity, whichever occurs first. In the phase I study, we evaluate the safety and tolerability of these peptide vaccine. In the following phase II study, we evaluate the immunological and clinical response of this vaccine therapy.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing VEGFR1 and VEGFR2 in people with Colorectal Cancer and Colon Cancer, run by Tokyo University at 1 site in Japan.
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 14 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: stopped early, as of the sponsor's last update on 29 Dec 2009. 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 Japan. 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 combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
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 stopped early (reason given: Lack of financial support). Results are not available in the source record.
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?
safety(Phase I:toxicities as assessed by NCI CTCAE version3) and efficacy(Phase II:Feasibility as evaluated by RECIST) (time frame: 2 months). 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 NCT00677612, which also lists 3 linked publications.
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 29 Dec 2009.
