STRICT - Surveillance With TRoponin During Immune Checkpoint Therapy

March 28, 2024 updated by: M.D. Anderson Cancer Center
To learn if monitoring blood levels of heart injury (troponin levels) in cancer participants treated with immune checkpoint inhibitors will lead to decreased heart-related side effects.

Study Overview

Detailed Description

Primary Objectives:

To compare the incidence of major adverse cardiovascular events between the 2 study arms. Major adverse cardiovascular events will be defined as the first of any of the following cardiac conditions to occur; Myocarditis CTCAE grade >=3, Ventricular tachycardia (>=30 seconds), Advanced atrioventricular block, Incident heart failure event, Cardiovascular mortality, Non-fatal sudden cardiac arrest, Acute coronary syndrome, Pericarditis, Pericardial tamponade.

Secondary Objectives:

  • Time from symptom onset to diagnosis of major adverse cardiovascular events
  • Time from symptom onset to diagnosis of myocarditis
  • Initial hospitalization duration for the adverse cardiovascular event from primary endpoint
  • Peak biomarker levels including troponin T, troponin I, creatine kinase, and creatine kinase myocardial band
  • Percentage of patients with negative workup for myocarditis
  • Percentage of patients requiring major cardiac testing including echocardiograms, cardiac magnetic resonance imaging, and/or invasive heart catheterization
  • Duration of interruption and/or discontinuation of immune checkpoint inhibitor therapy
  • Cancer progression free survival
  • Time to next cancer therapy

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

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers



Inclusion Criteria:

  • Male or female patient ≥18 years old
  • Plan for treatment with an immune checkpoint inhibitor as standard of care even if patient is also on an additional investigational cancer therapeutic
  • Willingness to provide informed consent

Exclusion Criteria:

  • Pregnant or breast-feeding
  • Inability to comply with planned study procedures
  • Major adverse cardiovascular event included in the primary outcome within the 30 days prior to enrollment
  • Any medical condition that could interfere with, or for which the treatment might interfere with the conduct of the study or interpretation of the study results, or that would, in the opinion of the investigator, increase the risk of the participant by participating in the study
  • Any factors that, in the Investigator's opinion, are likely to interfere with study procedures, such as history of noncompliance with scheduled appointments.

Design Details

  • Primary Purpose: Screening
  • Allocation: Randomized
  • Interventional Model: Single Group Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Troponin Surveillance
Participants in Group 1, will have blood tests performed every 2 weeks for 12 weeks.
Troponin will be monitored prior to each immune checkpoint inhibitor infusion for the first 12 weeks of therapy.
Experimental: Standard of Care
Participants in Group 2, will have standard of care testing for any heart-related side effects of immune checkpoint inhibitors.
Standard of care if symptoms arise then evaluation with cardiac biomarkers and/or further cardiac testing.
