About this study

Official title: A Phase II Study of Pembrolizumab and High-Dose Pemetrexed for the Treatment of Patients With Progressive Chordoma

Primary Objective:

  1. To determine objective response rate (ORR) according to RECIST v1.1 of pembrolizumab and high-dose pemetrexed in the treatment of patients with chordoma until disease progression. The OOR will be investigator assessed.
Read more

Secondary Objectives:

  1. To describe the adverse events associated with administering pembrolizumab and high-dose pemetrexed combination treatment.
  2. To determine disease control rate based on imaging and overall survival.
  3. To determine median PFS and PFS rates at 6, 9, 12, and 18 months.
  4. To evaluate changes in volumetric tumor measurements based on imaging.
  5. To determine the effects of combination treatment on quality of life, assessed by the EORTC-QLQ-C30 questionnaire.
  6. To assess tumor evolution over time in patients with chordoma based on imaging, and molecular profiling.
  7. To assess the pharmacodynamic effects of treatment in blood.

Exploratory Objective:

  1. To explore the relationship between molecular phenotype and patient response.
Read the detailed description

This purpose of this study is to test the effectiveness and safety of the research study drug combination of pembrolizumab and high-dose pemetrexed. Both drugs are approved by the U.S. Food and Drug Administration (FDA) for many different types of cancer but is considered investigational because it is not approved by the FDA for use in patients with a rare type of cancer called chordoma. Pembrolizumab (Keytruda) is approved for use in more than ten types of cancer. Pemetrexed (Alimta) is approved for use in patients with certain types of lung cancer called non-squamous non-small cell lung cancer (NSCLC) and malignant pleural mesothelioma. Pemetrexed is also approved for use with pembrolizumab and cisplatin or carboplatin for certain non-squamous NSCLC. The approved dose of pemetrexed is 500 mg/m2, but this study is evaluating a higher dose (900 mg/m2) in effort to deliver more drug to chordoma. Outcome measures will be monitored until disease progression, through study completion (estimated average of 2 years), or withdrawal from study.

Chordoma tumors can occur anywhere along the spine, from the head to the tailbone, and surgery and radiation therapy are currently used as treatment for chordoma. There are no drugs at this time that are approved for treating this cancer type. This study is being done to determine how the combination treatment regimen of pembrolizumab and high-dose pemetrexed might affect the growth of chordoma and to learn more about this regimen's safety in patients with chordoma.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Pembrolizumab and Pemetrexed Phase 2 in people with Chordomas and Chordoma, run by Saint John's Cancer Institute at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 31 inclusion and 49 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 27 Jan 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Naveed Wagle, MD (310-829-8265, Naveed.Wagle@providence.org), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Objective Response Rate (ORR) (time frame: Day 1 of study treatment until disease progression up to 2 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06794645, which also lists 4 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Jan 2025.
