TB-500 (Thymosin Beta 4 17-23 Fragment) for Cardiovascular Biomarkers in Stable ASCVD (TBRIDGE-CV)

March 17, 2026 updated by: Hudson Biotech

A Phase 1/2, Randomized, Double-Blind, Placebo-Controlled, Sequential Dose-Escalation Study of TB-500 (Thymosin Beta 4 17-23 Fragment) in Adults With Stable Atherosclerotic Cardiovascular Disease to Evaluate Safety, Tolerability, Pharmacokinetics, and Exploratory Cardiovascular Biomarkers

This fictional study is an example of a ClinicalTrials.gov-style record. It describes a Phase 1/2 trial evaluating the safety and tolerability of TB-500 (a 17-23 fragment of thymosin beta 4) versus placebo in adults with stable atherosclerotic cardiovascular disease (ASCVD). Exploratory endpoints assess vascular function and inflammation biomarkers

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 example record models common ClinicalTrials.gov data elements for an interventional study. Design overview: Participants with stable ASCVD will be enrolled into three sequential dose cohorts. Within each cohort, participants are randomized in a 3:1 ratio to TB-500 or matching placebo. Masking is maintained for participants, care providers, investigators, and outcome assessors. Intervention period: Study drug is administered by trained clinic staff during scheduled on-site visits over an 8-week dosing period, followed by a 4-week safety follow-up. The specific dose levels are protocol-defined and are not provided in this public example. Assessments: Safety assessments include adverse events, concomitant medications, physical examinations, vital signs, clinical laboratory testing, and 12-lead ECG. Exploratory cardiovascular assessments include brachial artery flow-mediated dilation (FMD) and blood-based biomarkers of inflammation and cardiac stress. Escalation and oversight: An independent safety review committee evaluates cumulative safety data after each cohort completes early follow-up before enrollment begins in the next cohort.

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
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Age 40-75 years, able to provide written informed consent.
  • Documented stable ASCVD (e.g., prior myocardial infarction >6 months ago, prior coronary revascularization, stable angina with objective evidence of ischemia, or symptomatic peripheral artery disease).
  • On stable guideline-directed medical therapy (e.g., statin and antiplatelet therapy unless contraindicated) for at least 8 weeks before screening.
  • Resting systolic blood pressure <160 mmHg and diastolic blood pressure <100 mmHg (with or without therapy).
  • Able and willing to comply with study visits and procedures.

Exclusion Criteria:

  • Acute coronary syndrome, stroke/transient ischemic attack, or coronary revascularization within 6 months before screening.
  • New York Heart Association (NYHA) class III-IV heart failure or left ventricular ejection fraction <35%.
  • Clinically significant arrhythmia requiring recent hospitalization or unstable antiarrhythmic therapy.
  • Severe renal impairment (eGFR <30 mL/min/1.73 m^2) or end-stage renal disease.
  • Clinically significant hepatic impairment (e.g., Child-Pugh class B/C) or ALT/AST >3x upper limit of normal at screening.
  • Active malignancy requiring systemic therapy (except adequately treated non-melanoma skin cancer) within the past 2 years.
  • Known autoimmune disease requiring systemic immunosuppression, or use of chronic systemic corticosteroids above physiologic replacement.
  • Pregnant or breastfeeding, or unwilling to use effective contraception during the study (if of childbearing potential).
  • Known hypersensitivity to peptide therapeutics or study formulation components.
  • Participation in another interventional clinical study or receipt of an investigational product within 30 days (or 5 half-lives, whichever is longer) prior to screening.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
