Study of Amblyomin-X in Advanced Solid Tumor (Amblyomin-X)

October 11, 2019 updated by: União Química Farmacêutica Nacional S/A

Phase I Study (First in Humans) of the Amblyomin-X in the Treatment of Patients With Advanced Solid Tumors Refractory or Without Indication / Access to Standard Treatment

Amblyomin-X is an inhibitor of Factor Xa that also acts as an apoptotic agent for tumor cells. In the case of in vitro assays, Amblyomin-X induces tumor cells to death and does not affect the viability of normal cells. When in vivo assays were performed on mice bearing tumors, treatment with Amblyomin-X caused a significant reduction in tumor mass and number of metastases.

Study Overview

Status

Status

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

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

This trial will be the first clinical study in humans with the product, which until then has been studied only in experimental models. Given the current epidemiological impact of cancer and the need to improve its systemic treatment, making it available to a larger portion of the Brazilian population, it is proposed to conduct the first Amblyomin-X study in cancer patients, more specifically those with advanced solid tumors For which there is no contraindicated or inaccessible therapeutic option established as the standard at the time of inclusion in the study.

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

18 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: Cohort 1
This cohort will include 3 patients with the first calculated dose of Amblyomin-X drug. The patient will receive the intravenous drug. If no Dose-limiting toxicity (DLT) in this group the study continues including the next cohort. However, if If only one patient in a given cohort develops DLT, three more patients will be included at that dose level, up to a maximum total of six patients per dose level. If two or more of the three patients of a certain dose level develop DLT, this dose level is considered very toxic, and the study does not proceed. If this occurs at the first dose level, the study will be finalized. If only one in six patients at a dose level develops DLTs, escalation proceeds until Tolerated Maximum Dose.
