About this study
Official title: Phase I Active Immunotherapy Trial With a Combination of Two Chimeric (Trastuzumab-like and Pertuzumab-like)Human Epidermal Growth Factor Receptor 2 (HER-2) B Cell Peptide Vaccine Emulsified in ISA 720 and Nor-MDP Adjuvant in Patients With Advanced Solid Tumors
This phase I trial studies the side effects and best dose of vaccine therapy in treating patients with metastatic solid tumors. Vaccines made from antibodies and peptides combined with tumor cells may help the body build an effective immune response to kill tumor cells.
Read the detailed description
PRIMARY OBJECTIVES:
- To perform early phase clinical trial assessing safety and clinical toxicity of immunization, and as well as to establish an optimal biological dose (OBD) of combination vaccines with n-muramyldipeptide derivative (nor-MDP) as adjuvant emulsified in Montanide (ISA 720).
II. To establish whether an OBD of two combination vaccines is achieved. III. To measure both humoral and cellular immune responses including the specificity, class and kinetics of anti-human epidermal growth factor receptor-2 (HER-2) peptide.
IV. To evaluate whether the combination of HER-2 epitopes show therapeutic benefit, provide synergistic and/or additive effects and to enumerate mechanisms of action.
SECONDARY OBJECTIVES:
- To collect and analyze post-immune sera and peripheral blood cells for additional six months post the last injection.
II. To document any clinical responses that may occur.
OUTLINE: This is a dose-escalation study.
Patients receive a HER2/neu peptide vaccine comprising measles virus epitope MVF-HER-2 (266-296) and MVF-HER-2 (597-626) emulsified with nor-MDP in ISA 720 intramuscularly (IM) on day 1. Treatment repeats every 21 days for up to 3 courses in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up for 30 days.
OUTLINE: EXTENSION TRIAL AT OBD
The dose-escalation (4 cohorts) has successfully completed with the accrual of 24 patients and the Optimum biological dose (OBD) has been determined as the dose at cohort level 2.
The next phase of the study progresses directly into an extension trial at the OBD. 12 patients will be accrued at that level. The extension cohort will be open to only HER-2 and/or EGFR overexpressing cancers. Patients (all gastrointestinal,ovarian and breast must have received no more than three prior cytotoxic chemotherapy regimens in the last two years after standard therapy. Patients (breast, ovarian and gastrointestinal cancers) must have received no more than three prior cytotoxic chemotherapy regimens in the last two years after standard therapy.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
HER-2 vaccineBiological
Also called Synthetic peptides of HER-2 comprising B cell epitopes with a Promiscuous T cell epitope of Measles Virus.
Three intramuscular (IM) injections (separated by 21 days) of a mixture of two peptides {MVF-HER-2(597-626) and MVF-HER-2 (266-296)} vaccine emulsified with nor-MDP in ISA 720 vehicle. Increasing doses of the combined vaccine preparation emulsified with nor-MDP (0.025) mg and Montanide ISA 720 will be administered in a final volume of 1.0 ml. Starting at dose level 1, 1.0mg of each peptide will be used for vaccination. In increasing dosing cohorts 1.5mg, 2.0mg and 2.5mg will be used. Patients may also receive 6 months booster shots.
Extension HER-2 vaccine trial at OBDBiological
Three intramuscular (IM) injections (separated by 21 days) of a mixture of two peptides {MVF-HER-2(597-626) and MVF-HER-2 (266-296)} vaccine emulsified with nor-MDP in ISA 720 vehicle. The dose level has been determined to be cohort 2. The combined vaccine preparation consists of 1.5mg of each of the HER-2 vaccine emulsified with nor-MDP (0.025) mg and Montanide ISA 720 will be administered in a final volume of 1.0 ml. Patients may also receive 6 months booster shots.

What is being measured
The primary outcome is the main question the study is designed to answer.
Type and duration of immune response measured over time to repeat vaccine administration
Immune response will be defined by Enzyme-linked immunosorbent assay (ELISA), Flow cytometry, T-cell proliferation and cytokine. The magnitude of antibody levels will be assessed to the vaccine and HER-2 over-expressing cells (e.g.,BT474). Lymphoproliferative responses will be assessed by a non radioactive cell proliferation assay Bioplex human isotyping kit will be used to assess antibody types and cytokine profiles.
Measured: up to 6 months
Clinical benefit will be assessed
Will re-evaluate disease status with tumor markers and RESIST criteria,or full evaluation upon development of new symptoms
Measured: up to 6 months
Secondary outcomes (1)
Evaluation of safety and toxicity at regular intervals by NCI common toxicity criteria (CTCAE v 4.0)
Safety will be defined if patients are able to receive all 3 vaccinations without dose-limiting toxicity (DLT), any incidence of grade 3 hematologic and non-hematologic toxicity or any incidence of Grade 4 toxicity. The development of a positive skin test to the vaccine immediate hypersensitivity
Measured: up to 6 months

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing HER-2 vaccine and Extension HER-2 vaccine trial at OBD in people with Malignant Solid Tumour and Breast Cancer, run by Robert Wesolowski 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 19 inclusion and 18 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 15 Sep 2023. 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 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.
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?
Type and duration of immune response measured over time to repeat vaccine administration (time frame: up to 6 months). The study lists 2 primary outcomes in all. 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 NCT01376505, which also lists 1 linked publication.
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 Sep 2023.
