Dose Escalation Study of TAB08 in Patients With Advanced Solid Neoplasms (TAB08)

October 5, 2021 updated by: Theramab LLC

A Phase 1b Multiple Dose Escalation Study of TAB08 in Patients With Advanced Solid Neoplasms

The purpose of this study is to determine the maximum tolerated dose (MTD) and recommended Phase 2 dose of TAB08 when administered intravenously (i.v.) to patients with advanced solid malignancies.

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

This is an open-label, multi-center, sequential groups, dose escalation study of TAB08 in patients with metastatic or unresectable advanced solid malignancies. The study will consist of 2 parts: a dose-escalation part with a standard "3+3" design, followed by a dose-expansion part once the maximum tolerated dose (MTD) has been determined.

Patients must have documented recurrent or refractory solid tumors; patients enrolled in the dose-expansion part of the trial must have least one lesion that may qualify as a target lesion based on the RECIST 1.1 criteria. Following the provision of signed informed consent, patients will be screened for entry into 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

14 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

  7. At least 2 weeks or at least 5 half-lives must have elapsed since prior treatment with chemotherapy, targeted therapy, radiotherapy, immunotherapy, or investigational anti-cancer therapy prior to study drug administration. The maximum washout period will not exceed 4 weeks. .

Exclusion Criteria:

  1. Subjects with an uncontrolled concurrent illness, including, but not limited to the following: ongoing active infection requiring systemic treatment; uncontrolled endocrine disease; diabetes mellitus or chronic obstructive pulmonary disease (COPD) requiring hospitalization within the preceding 6 months.
  2. Subjects with uncontrolled arterial hypertension, heart failure by New York Heart Association (NYHA) Class 3 or 4, left ventricular ejection fraction (LVEF) < 50% by echocardiography, myocardial infarction, acute coronary syndrome and/or QT prolongations within the preceding 6 months or history of cerebrovascular accidents including episodes of transient ischemic attacks.
  3. Subjects with altered mental status or psychiatric illness or social circumstances that would limit compliance with the study requirements and/or obscure the results.
  4. Immunocompromised subjects, e.g., subjects known to be infected with human immunodeficiency virus (HIV) by medical history, and subjects with active hepatitis A, B, or C by medical history.
  5. Subjects having untreated or symptomatic brain metastasis, or subjects with leptomeningeal disease. (Subjects with treated metastases, who are off corticosteroids and who are neurologically stable for at least 2 months may participate in the trial.)

  8. Women who are pregnant or nursing.
  9. Subjects with any other disease, metabolic dysfunction, physical examination finding, or clinical laboratory finding that, in the opinion of the investigator, contraindicates use of the investigational drug, or may render the subject as excessively high risk for treatment complications.
  10. Subjects with any other condition as determined by medical history, including substance abuse that, in the opinion of the investigator, would render the subject unable to cooperate in the trial or place the subject at undue risk.
