Clinical Trial Summary

The goal of this study is to evaluate the safety and clinical efficacy of personalized chemotherapy with low doses of cyclophosphamide administered taking into account the reparative cycle of tumor cells in participants with breast cancer (stage IV or disease progression). The main question it aims to answer is: Does personalized chemotherapy of breast cancer with low doses of cyclophosphamide, taking into account the reparative cycle of tumor cells, lead to a significant reduction in tumor size and improvement in the visual status of controlled tumor foci relative to their initial state? During the preparatory stage, a tumor sample from participant is harvested intraoperatively. The primary culture is obtained from this tumor tissue sample. Repair cycle time is estimated, and the day when tumor cells are synchronized at the cell cycle G2/M phase is identified. The schedule of administering cyclophosphamide and DNAmix complex composite preparation is calculated according to the resulting time points. According to the elaborated regimen, the participant receives 4 intravenous cyclophosphamide injections at the dose of 300 mg/m2 in combination with 4 injections of 1-12 mg of DNAmix administered into prominent tumor nidi and lymph depots. The participant receives from 2 to 6 courses of therapy. The interval between courses is 21 days.

Outcome

Type Measure Description Time frame Safety issue
Primary The size of tumor foci Estimation of the size and visual condition of controlled tumor foci relative to their initial state. Tumor response assessment using the Response Evaluation Criteria In Solid Tumors (RECIST 1.1). 2 months
Secondary The quality of life score Changes in participants' quality of life during the therapy (score) according to the European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30, version 3.0). The scale ranges in score from 0 to 100. Higher score means higher quality of life. 2 months
Secondary The immunomodulatory effect The number of CD4+CD25+FoxP3+ regulatory T cells and CD8+CD107a+ T cells is mesuared in participants' blood before therapy and after 2 months using corresponding antibodies. Increase in number of these cells by 14% or more means the development of the adaptive antitumor immune response. 2 months
