Safety and Efficacy Study of Epitope Peptide To Treat HLA-A*24 or A*02-positive Advanced Solid Tumors

March 15, 2019 updated by: Yataro Daigo, Shiga University

Phase I/II Study Using Epitope Peptide Restricted to HLA-A*24 or HLA-A*02 in Patients With Advanced Solid Tumors That Are Refractory to Standard Therapy

In this study, the investigators examine using a combination of two types of HLA-A*2402 (or HLA-A*0201)-restricted epitope peptides, which were derived from VEGF-R1 and VEGF-R2 the safety, immunogenicity, and antitumor effect of vaccine treatment for advanced solid tumor patients who are refractory to standard therapy.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The purpose of this study is to evaluate the safety, tolerability, immune response and clinical efficacies of HLA-A*2402 or HLA-A*0201 restricted epitope peptides (VEGF-R1 and VEGF-R2) emulsified with Montanide ISA 51 for advanced solid tumors.

In this phase I/II trial, the investigators examine using a combination of the two peptides the safety, immunogenicity, and antitumor effect of vaccine treatment for HLA-A*2402 or HLA-A*0201-positive advanced solid tumor patients who are refractory to standard therapy.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
