Targeted Delivery of Chemotherapy With Ultrasound and Microbublles (SONCHIMIO)

January 6, 2023 updated by: University Hospital, Tours

Targeted Delivery of Chemotherapy With Ultrasound and Microbubbles

The oscillations of ultrasound (US) contrast agent microbubbles under their activation by US waves engender a modulation of the permeability of biological barriers amplifying hence the extravasation of drugs and/or fluorescent markers through a process known as sonoporation. In such a way, the bioavailability of the therapeutic agent is augmented only in the area where US waves are focused. The objective now is to translate this therapeutic approach to the clinic by performing a feasibility study with the development of a therapy regime optimized for hepatic metastases of colorectal cancer.

In order to demonstrate the clinical feasibility of the therapeutic approach based on ultrasound and microbubbles, we will focus on patients with liver metastases of colorectal cancer treated with monoclonal antibodies in combination with chemotherapy.

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

Despite the increasing number of active molecules and the availability of news targeted therapies for cancer, therapeutic achievements remain modest for a number of tumor types. One of the major obstacles is inherent to the absence of specific delivery in the tumor tissue.

We have demonstrated recently that the oscillations of ultrasound (US) contrast agent microbubbles under their activation by US waves engender a modulation of the permeability of biological barriers amplifying hence the extravasation of drugs and/or fluorescent markers through a process known as sonoporation. In such a way, the bioavailability of the therapeutic agent is augmented only in the area where US waves are focused. The objective now is to translate this therapeutic approach to the clinic by performing a feasibility study with the development of a therapy regime optimized for hepatic metastases of colorectal cancer.

In order to demonstrate the clinical feasibility of the therapeutic approach based on ultrasound and microbubbles, we will focus on patients with liver metastases of colorectal cancer treated with monoclonal antibodies in combination with chemotherapy.

The work aims into evaluating the therapeutic efficacy of the proposed approach on a number of selected patients. We will follow the usual treatment schemes and we will apply imaging protocols to visualize tumor progression.

This technique of optimization of the intratumoral availability of anticancer drugs and based on sonoporation will improve the efficacy and safety of systemic chemotherapy by providing increased tumor uptake relative to normal tissue. This technique provides an ideal and easy strategy to optimize intratumoral drug delivery.

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.
