Systemic Therapy Table

Learn more about systemic therapyTo assist chordoma patients who are considering systemic therapies, we have created a resource designed to clarify the options that are currently available through clinical trials or off-label prescription. This resource is meant to make it easier for chordoma patients and caregivers to research treatment options.

The table below includes therapies corresponding to all mechanisms of action our Medical Advisory Board (MAB) has identified as relevant to chordoma treatment. A mechanism of action is the way a systemic therapy works to attack tumor cells. In the case of targeted therapies, for instance, the mechanism of action is to block a molecular target that the tumor depends on for survival. For example, the mechanism of action of an EGFR inhibitor is to block the EGFR protein, which would be referred to as the drug’s target.

How to use the Systemic Therapy Table:

  • We encourage patients who are considering systemic therapies to show this table to their doctors to help guide discussions about treatment options. Click here to view the table as a spreadsheet that you can download or print out to take with you to your appointments.
  • Follow the links under “Mechanism of action” to see a summary of the published supporting evidence.
  • Follow the available links under “Open clinical trial” for more information about those trials.
  • Visit the Systemic Therapy for Chordoma page to learn more about when these treatments are recommended.

Chordoma Foundation Medical Advisory Board recommendations

Although each patient’s situation is unique, in general, our Medical Advisory Board (MAB) recommends that patients considering systemic therapy treatment options do so in the following order of priority, in consultation with a chordoma-experienced medical oncologist:

1. Chordoma-specific clinical trials
Chordoma-specific clinical trials are trials designed specifically for chordoma patients or those that are enrolling a group of chordoma patients to a specific arm of the trial.

2. Other relevant clinical trials recommended by an experienced physician
If you are not eligible for any chordoma-specific trials, ask your oncologist about other clinical trials that may be open to you.

3. Off-label therapy with evidence of clinical benefit for chordoma patients 
While there are currently no systemic therapies approved for the treatment of chordoma, some therapies that are approved for the treatment of other cancers have shown activity in chordoma. The Systemic Therapy Table above includes information on these treatments. In some countries, doctors can choose to prescribe these to chordoma patients if they believe they will be of benefit to the patient.

The Chordoma Foundation is a resource for clinical trials. Our Clinical Trials Catalogue lists all chordoma-specific clinical trials, as well as trials that our MAB has determined are relevant to chordoma patients based on what we know about the biology of chordoma in relation to the type of drug being studied in the trial. Listings in the Catalogue include information on the treatment being studied, the locations of trial sites, and links to learn more about the trial.
