About
It is planned to conduct an open-label, prospective, randomized clinical study of the efficacy, tolerability and safety of a single intraperitoneal administration of the investigational drug Prospidelong at a dose of 4000 mg (2000 mg in terms of prospidium chloride) in patients with disseminated gastric cancer.
In total, the study plans to include 120 patients aged 18 to 75 years inclusive, including 60 patients in the study group and 60 in the comparison group. The study consists of daily examination of patients throughout the entire period of hospitalization and subsequent visits.

It is planned to conduct an open-label, prospective, randomized clinical study of the efficacy, tolerability and safety of a single intraperitoneal administration of the investigational drug Prospidelong at a dose of 4000 mg (2000 mg in terms of prospidium chloride) in patients with disseminated gastric cancer.
In total, the study plans to include 120 patients aged 18 to 75 years inclusive, including 60 patients in the study group and 60 in the comparison group. The study consists of daily examination of patients throughout the entire period of hospitalization and subsequent visits.
Inclusion - preliminary interview with the patient and signing of informed consent.
Informed consent is the free and voluntary expression of the subject's desire to participate in a specific study after receiving information about all aspects of this study that are significant for the subject's decision to participate, and in the case of minors and incapacitated subjects, the permission or consent of their legal representatives to include such subjects into the study. Informed consent is documented by signing and dating the informed consent form.
Signed and dated informed consent must be obtained from each patient or, if the patient is unable to make an informed decision due to health reasons, from the patient's spouse/close relative (close relatives include parents, adult children, siblings, grandparents) , grandchildren), and the patient's signed informed consent to participate in the study must additionally be obtained as soon as his health condition allows it.
Before signing informed consent, all potential participants should be informed of the nature and purpose of the study, including possible risks and unwanted effects, and given sufficient time to read and understand the information presented. The researcher should answer any questions that arise. The researcher must also sign an informed consent form. After signing, one copy of the informed consent is given to the patient (the patient's spouse/close relative) and one copy remains at the center for storage in the Researcher's file.
Preparatory period - includes screening patients for compliance with inclusion and exclusion criteria, determining the initial condition of the patient. During screening, a medical history will be taken and the patient's date of birth, age and gender will be recorded. When collecting anamnesis, you should clarify data on concomitant diseases and medications used to treat the main and concomitant diseases, drug intolerance, and allergic reactions.
During screening, the patient's medications and procedures performed over the past 30 days must also be recorded. Registration of concomitant therapy for the main and concomitant diseases is carried out at each visit. All changes in the treatment regimen for the underlying disease (changes in the standard therapy received by the patient as part of rehabilitation treatment in the postoperative period and during systemic chemotherapy drug treatment after discharge from the hospital) and in the treatment of concomitant diseases are recorded: changes in the dose and frequency of administration of previously prescribed drugs, prescription new drugs.
After signing the informed consent and screening, patients undergo a general clinical examination in accordance with the clinical protocol "Algorithms for the diagnosis and treatment of malignant neoplasms" (approved by Resolution of the Ministry of Health of the Republic of Belarus No. 60 of 07/06/2018).
The scope of research before treatment includes:
According to indications: fibrocolonoscopy, laparoscopy, irrigoscopy, angiography, MRI, scintigraphy of skeletal bones, computed tomography - for no more than 7 days before inclusion.
Preliminary selection. Based on the results of the preoperative examination, a preliminary selection of patients with resectable gastric cancer is carried out.
The final selection is carried out intraoperatively based on the results of the abdominal cavity revision (see above). Patients with the presence of peritoneal dissemination, confirmed by morphological examination, are selected. The scope of surgical intervention will be limited to biopsy of areas of the peritoneum with disseminates. Randomization of patients will be carried out by an employee of the department of automated control systems of the Republican Scientific and Practical Center for OMR named after. N.N. Aleksandrova using the "Randomization" software based on random number generation. The result of randomization will be confirmed by protocols of the established form. During randomization, patients will be divided into the following groups: main (experimental) and control group. Patients of the main group, after placing a control drainage in the abdominal cavity, will undergo intraperitoneal application of the study drug Prospidelong at a dose of 4000 mg. Patients in the control group did not undergo intraperitoneal administration of Prospidelong.
Individual registration cards (IRCs) are created for patients included in a clinical trial.
Recruitment of patients into the groups will be done using a sequential enrollment method. Patients excluded from the study for any reason will not be replaced.
Treatment period Intraperitoneal use of the study drug Prospidelong will be a single dose. Subsequent treatment of patients will be carried out in accordance with the clinical protocol "Algorithms for the diagnosis and treatment of malignant neoplasms" (approved by Resolution of the Ministry of Health of the Republic of Belarus No. 60 of 07/06/2018).
The scope of research in the study groups in the postoperative period will include:
Deviations in the timing of ultrasound and CT of the abdominal cavity are allowed if progression of the tumor process is suspected (CT is performed only if progression of the disease is suspected and other research methods are not informative).
After using the study drug Prospidelong, the researcher evaluates the immediate and immediate results and enters the evaluation data into the CRF. The assessment of the necessary parameters is carried out in the hospital after surgery, as well as during subsequent visits to the patient for a follow-up examination within the specified time frame.
At each study visit, the patient's complaints will be assessed by the study physician.
