Autologous Dendritic Cell Vaccine in Patients With Soft Tissue Sarcoma

Non-randomized Single-center Study Phase II Evaluating the Efficacy and Toxicity of Autologous Dendritic Cell Vaccine Loaded With Allogeneic Tumor Lysate Expression of Cancer Testis Antigens in Patients With Soft Tissue Sarcoma

The purpose of this study is to achieving a six-month progression free survival (PFS) of patients receiving autologous dendritic cell vaccine (ADKV) loaded with allogeneic tumor lysate expression of cancer-testis antigens (CTA) in patients with soft tissue sarcomas

Vaccination is carried out on the planned days ± 3 days

1. All examinations must be performed before the vaccine is administered.

   • Full physical examination.
   • Assessment of vital signs (blood pressure, temperature, heart rate), the general condition of the patient and physical activity.
   • Evaluation of concomitant therapy.
   • Assessment of vital signs.
   • Laboratory safety and immunological indicators
   • Assessment of adverse events, symptoms and syndromes of the disease.

2. Introduction of CV in accordance with the dose determined for a given vaccination (see section 9.2. - procedures for delivery and use)

3. After administration, patients are observed for at least 1 hour. An assessment of vital indicators. Undesirable effects detected at the introduction are recorded.

• The failure of standard therapy
• Adequate amount of material for genetic research
• No active or chronic infection with HIV, Hepatitis B or Hepatitis C
• Men/Women of childbearing potential must use adequate contraception
• Hematology, liver function and renal function lab tests within required parameters

Exclusion Criteria:

• Untreated or uncontrolled brain metastases.

• Dementia or significantly altered mental status that would prohibit understanding or rendering of informed consent and compliance with protocol requirements.
• Pregnant or breastfeeding women.
• Prisoners or subjects who are compulsorily detained (involuntarily incarcerated) for treatment of either a psychiatric or physical (e.g. infectious) illness.
