Summary

This Trial tests if abatacept can reduce serious heart problems in patients with heart inflammation caused by cancer treatments. Abatacept calms the immune system by preventing certain immune cells from becoming fully active, reducing inflammation and damage. Abatacept has been approved by the US Food and Drug Administration for the treatment of rheumatoid arthritis, with or without methotrexate.

Who is the study for?
Adults hospitalized with myocarditis caused by recent immune checkpoint inhibitor therapy for cancer, who are on or starting high-dose corticosteroids. Participants must have certain blood cell counts within normal ranges, not be pregnant or breastfeeding, and agree to use contraception. Exclusions include active infections like TB, recent live vaccines, other immunosuppressive treatments, and participation in another interventional study.
What is being tested?
The trial is testing if abatacept can reduce major cardiac events compared to a placebo in patients with myocarditis following cancer treatment with immune checkpoint inhibitors. The main outcome measures include cardiovascular death and various heart-related complications.
What are the potential side effects?
Potential side effects of abatacept may include increased risk of infections due to immune system suppression, possible allergic reactions at the injection site or throughout the body, headache, nausea, and potential worsening of any current infections.

Trial Design

2Treatment groups
Experimental Treatment
Placebo Group
Group I: Abatacept plus standard of careExperimental Treatment1 Intervention
Abatacept (10 mg/kg) will be administered IV after randomization, again at 24 hours after first study drug treatment, at 14 days after first study drug treatment and an optional 4th dose at 28 days.
Group II: Placebo plus standard of carePlacebo Group1 Intervention
Placebo will be administered at the same intervals.

Mechanism Of Action
Side Effect Profile
Prior Approvals
Other Research
Immunotherapies, such as abatacept, work by modulating the immune system to enhance its ability to fight cancer. Abatacept specifically targets T-cell activation pathways, reducing the immune response that can lead to adverse cardiac events in patients treated with immune checkpoint inhibitors. This mechanism is crucial for cancer patients as it helps manage immune-related side effects while maintaining the therapeutic benefits of immunotherapy. Other common treatments include checkpoint inhibitors that block proteins like PD-1, allowing T-cells to attack cancer cells more effectively. These therapies are significant because they offer targeted approaches to boost the body's natural defenses against cancer, potentially leading to better outcomes and fewer side effects compared to traditional treatments.
