Effect of Refnot on Immunity in Cancer Patients (R-2)

June 8, 2023 updated by: Refnot-Pharm Ltd
The study was planned to include disseminated patients with various solid tumors (melanoma, soft tissue sarcoma, breast cancer, colon cancer, etc.). The study drug was administered subcutaneously at a dose of 400,000 IU once a day, 3 times a week (every other day), for 4 weeks. In the absence of disease progression - an additional 4 weeks.

Study Overview

Status

Status

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

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

The study was planned to include 50 disseminated patients with various solid tumors. The patients were divided into 2 groups: 1 - Refnot, monotherapy, 2 - Refnot together with chemotherapy.

Refnot is administered at a dose of 400,000 IU subcutaneously 3 times a week for 4 weeks. 4 weeks constitute 1 course of treatment with Refnot. Immediately before use, 1 ml of water for injection is added to 4 vials (100,000 IU each) or to a vial containing 400,000 IU. After dilution, the drug is injected subcutaneously into the outer surface of the shoulder or thigh. Injection sites should alternate. In the absence of progression of the disease - an additional 4 weeks. Chemotherapy may be used after 4-8 weeks of Refnot use.

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

  • Adult
