Agnostic Therapy in Rare Solid Tumors

Exploring new treatments for uncommon solid tumors through clinical trials.

Phase 2
The ANTARES study is testing a medicine called nivolumab on people with rare forms of cancer that have spread or grown despite other treatments. This trial is called a **basket trial** because it focuses on cancers with a similar trait, not where they started. Nivolumab is an antibody that helps the immune system find and fight cancer cells that show a protein called **PD-L1**. The study lasts up to 12 months and aims to discover how well nivolumab works and how safe it is. Only adults with rare cancers that show PD-L1 and have not responded to other treatments can join. **Key Points:** - Participants receive treatment for a maximum of 12 months or until the cancer progresses. - The study takes place at multiple centers and is expected to last four years. - Participants must agree to use contraception and follow other safety measures during and after the study. **Eligibility:** Adults 18+, with specific rare cancers showing PD-L1, who haven't responded to other treatments. Conditions like active infection or recent major surgery may exclude participation.

FAQs

Learn more about clinical trials

What is a clinical trial?

A clinical trial is a study designed to test specific interventions or treatments' effectiveness and safety, paving the way for new, innovative healthcare solutions.

Why should I take part in a clinical trial?

Participating in a clinical trial provides early access to potentially effective treatments and directly contributes to the healthcare advancements that benefit us all.

How long does a clinical trial take place?

The duration of clinical trials varies. Some trials last weeks, some years, depending on the phase and intention of the trial.

Do I get compensated for taking part in clinical trials?

Compensation varies per trial. Some offer payment or reimbursement for time and travel, while others may not.

How safe are clinical trials?

Clinical trials follow strict ethical guidelines and protocols to safeguard participants' health. They are closely monitored and safety reviewed regularly.
