About this study

Official title: Phase I/IIa Study of Immunization With Frameshift Peptides Administered With Montanide® ISA-51 VG in Patients With Advanced MSI-H Colorectal Cancer

Patients with advanced microsatellite unstable (MSI-H) colorectal cancer will be vaccinated with three so called frame shift peptides (FSPs), AIM2(-1), HT001(-1) and TAF1B(-1) combined with Montanide® ISA-51 VG. By this, an immune response directed against MSI-induced FSPs that are shared by the majority of MSI-H colorectal cancers can be induced. The aim is to show that vaccination against MSI-induced FSPs is safe and can induce or enhance immune responses against MSI-H colorectal cancer-associated antigens.

Read the detailed description

The present study is initiated to evaluate vaccination with MSI-specific FSPs in patients with MSI-H colorectal cancer. Specifically, the present study aims at the following questions:

  • Evaluation of potential toxicity of the FSP AIM2(-1), HT001(-1), TAF1B(-1)
  • Evaluation of the immune response in patients with advanced MSI-H colorectal cancer before vaccination and after vaccination with the FSP AIM2(-1), HT001(-1), TAF1B(-1)

In this context, the present study shall demonstrate whether application of FSP in a vaccination approach is associated with the induction of peptide-related toxicity. Hence, the study marks the first step towards the application of FSP in humans, as it provides information on the safety of FSP as vaccination agents for the first time. Moreover, the study shall provide initial information, whether vaccination with FSP can induce FSP-specific immune responses in patients with MSI-H colorectal cancer. Thus, it shall provide information, whether FSPs AIM2(-1), HT001(-1), and TAF1B(-1) have the potential to elicit peptide-specific immune responses and therefore represent suitable targets for the induction of tumor antigen-specific immune responses in patients with MSI-H tumors.

The present study marks an important milestone towards a potential application of MSI-specific FSP as therapeutic agents in the management of patients with MSI-H tumors, particularly patients with MSI-H colorectal cancer. Long-term goal of this approach is to develop novel tools for (1) the palliative and/or adjuvant therapy of patients with advanced MSI-H colorectal cancer and (2) the preventive application of FSPs in mutation carriers of the HNPCC/Lynch syndrome.

What is being measured

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

  1. immune response against FSP peptides

    A positive immune response is defined as positive delayed-type hypersensitivity (DTH) response against at least one of the peptides or a humoral (ELISA for the detection of FSP-specific IgG/IgM/IgA) and/or CD8 and/or CD4 cellular (IFN gamma ELISpot for the detection of FSP-specific T cells) immune response exceeding the assay specific cut-off values for a positive response against at least one of the three peptides

    Measured: every two weeks

Secondary outcomes (2)

  1. Tumor response

    Tumor response is assessed by CT or MRI scans according to RECIST.

    Measured: every 8 weeks

  2. safety

    Safety as assessed by number and severity of adverse events categorized according to CTC criteria v4.0 and the probability of the induction of immune tolerance. Immune tolerance is defined as significant and sustained decline of antigen-specific cellular immune responses after vaccination compared to the antigen-specific cellular immune response measured before vaccination , as assessed by Interferon-gamma (IFN-g) ELISpot using assay-specific cut-off values.

    Measured: up to 8 months

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing FSP peptides in people with Colorectal Cancer, run by Oryx GmbH & Co. KG at 1 site in Germany.

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 15 inclusion and 14 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 23 Jun 2015. 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 Germany. 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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

immune response against FSP peptides (time frame: every two weeks). 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 NCT01461148, which also lists 2 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 23 Jun 2015.
