Autologous Antigen-activated Dendritic Cells in the Treatment of Patients With Colorectal Cancer

July 11, 2017 updated by: Research Institute of Fundamental and Clinical Immunology

Investigation of the Clinical and Laboratory Efficacy of Autogemotherapy Based on Autologous Antigen-activated Dendritic Cells in the Treatment of Patients With Colorectal Cancer

The purpose of this work: to assess the tolerability and effectiveness of the autogemotherapy method on the basis of autologous antigen-activated dendritic cells in the treatment of patients with colorectal cancer.

This technology is intended for complex treatment of patients with colorectal cancer and is aimed at preventing the occurrence and treatment of secondary foci. The need for this technology is justified by the widespread occurrence of colorectal cancer, a decrease in the average age at onset of the disease, and the chemoresistantness of locally advanced forms of cancer.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Unknown

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

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Currently, technologies are being developed to improve the clinical outcomes of patients with complex treatment of colorectal cancer. Many patients are immunosuppressed after surgical, radiation and chemotherapeutic treatment, which leads to dysfunction of T cells, resulting in tumor cells avoiding immune surveillance. Restoration of antitumor immunity during immunotherapy is one of the modern approaches in the treatment of colorectal cancer, which contributes to the formation of an effective specific immune response, the destruction of tumor cells while minimizing toxicity. Dendritic cells (DC) and the lymphocytes induced by them are one of the most effective methods for the destruction of residual cancer cells, which are the leading cause of relapse and metastasis.

Interventional

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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.

Ages Eligible for Study

30 years to 70 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  1. For the first time established morphologically confirmed diagnosis of colorectal cancer
  2. Patients with II A, II B, II C, III A, III B, III C stages of colorectal cancer;
  3. Patients with progressive or primary IV stage of colorectal cancer with cytologically confirmed and accessible soft tissue metastases;
  4. Absence of severe somatic pathology in which medical intervention (at the stage of obtaining biological material or the stage of immunotherapy) will only worsen the patient's condition,
  5. The patient's desire.

Exclusion Criteria:

  1. Pregnancy at any time,
  2. Impossibility of correction of therapy of concomitant diseases, if the taken preparations are proved to influence the immune status,
  3. Rapid progression of the underlying disease, in which the use of immunotherapy is deontologically unjustified,
  4. Individual intolerance to the components of the vaccine and / or the development of severe side effects on any of the components,
  5. Refusal of the patient to participate in the study in oral or written form.
  6. Patient involvement in any other clinical study (including those that the patient has not been informed by the direct oncologist who has been treated, but which has become known already after the beginning of any stage of the study).

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Сytotoxicity
Time Frame: 6 months
A study of the cytotoxic activity of peripheral blood mononuclear cells against tumor cells of the COLO 320 HSR line. The result will be presented as the level of cytotoxicity (%) against the cells of the tumor line. The determination of cytotoxicity is carried out using a lactate dehydrogenase test (Promega). The level of the enzyme is proportional to the level of cytotoxicity.
6 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

Time Frame
Parameters of peripheral blood
Time Frame: 6 months
Leukocyte formula, the enzyme content (lactate dehydrogenase, alkaline phosphatase, liver enzymes) of C-reactive protein, creatinine

Immune status indicators
Time Frame: 6 months
