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

NCT03214939 | Unknown Early Phase 1

Brief Summary

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.

Conditions

Colorectal Cancer

Keywords

dendritic cell, IL-12, IL-18, cytotoxicity

Outcome Measures

Primary Outcomes (1)

• Сytotoxicity

  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 Outcomes (5)

• Parameters of peripheral blood

  6 months

• Immune status indicators

  6 months

• The content of immunosuppressive populations

  6 months

• Interrogation of the patient using a visual analogue scale

  6 months

• Relapse-free period

  36 months

Study Arms (1)

EXPERIMENTAL

Intravenous administration dendritic cell and activated mononuclear cells at least 3 times 20-30 million cells / injection

Biological: Immunotherapy based on dendritic cells

Eligibility Criteria

• Age: 30 Years - 70 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• For the first time established morphologically confirmed diagnosis of colorectal cancer
• Patients with II A, II B, II C, III A, III B, III C stages of colorectal cancer;
• Patients with progressive or primary IV stage of colorectal cancer with cytologically confirmed and accessible soft tissue metastases;
• 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,
• The patient's desire.

You may not qualify if:

• Pregnancy at any time,
• Impossibility of correction of therapy of concomitant diseases, if the taken preparations are proved to influence the immune status,
• Rapid progression of the underlying disease, in which the use of immunotherapy is deontologically unjustified,
• Individual intolerance to the components of the vaccine and / or the development of severe side effects on any of the components,
• Refusal of the patient to participate in the study in oral or written form.
• 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).
