Nivolumab + stereotactic radiosurgery
Clinical trial of nivolumab with or without stereotactic radiosurgery in treating patients with recurrent, advanced, or metastatic chordoma
Doctors at Johns Hopkins Hospital and Memorial Sloan Kettering Cancer Center are now enrolling chordoma patients in a Phase 1 Research studies involving human subjects that are done to test whether a treatment is safe, and how well it will work to treat a specific disease. studying the safety and initial effectiveness of the Systemic therapies that are designed to teach the immune system how to find and destroy cancer cells. drug nivolumab with and without A type of external beam radiation that uses special equipment to position a patient and precisely deliver radiation to tumors in or near the brain, over a small number of treatments. (A type of external beam radiation that uses special equipment to position a patient and precisely deliver radiation to tumors in or near the brain, over a small number of treatments.). The goal of these therapies is to harness the body’s own immune system to more effectively fight chordoma.
This research study is designed specifically for chordoma patients 15 years or older with recurrent or metastatic tumors. The primary goal of this research study is to determine the safety of nivolumab alone or in combination with SRS for treating chordoma. The secondary goal is to determine whether these therapies can shrink or stop the growth of chordoma tumors. Dr. Michael Lim is the Principal Investigator at Johns Hopkins Hospital and Dr. Yoshiya (Josh) Yamada is the Principal Investigator at Memorial Sloan Kettering.
Why this trial is being done
The immunotherapy drug nivolumab helps the immune system destroy tumor cells by blocking proteins called immune checkpoint molecules that cancer cells use to avoid attack by the immune system. Known as a “checkpoint inhibitor,” nivolumab is currently approved to treat several tumor types including melanoma, kidney cancer, lung cancer and bladder cancer. Recent laboratory research has shown that chordomas produce the same checkpoint molecules as these cancers, suggesting that a checkpoint inhibitor such as nivolumab might also be able to help the immune system more effectively fight chordoma. This research study is the first to test a checkpoint inhibitor for the treatment of chordoma.
One group of participants in this study will receive nivolumab alone, which is intended to stimulate the immune system to attack the tumor. A second group will receive nivolumab in combination with stereotactic radiosurgery (SRS). SRS, which delivers a high dose of focused radiation to a tumor over a short period of time, is already a standard treatment that is used to help control advanced or When tumors have spread to other parts of the body from the original tumor site. chordoma tumors (it is sometimes called CyberKnife or Gamma Knife, which are the names of machines used to deliver the radiation). Doctors believe SRS triggers an immune response by causing tumor cells to burst, exposing their abnormal contents to the immune system. It may also make tumor cells more sensitive to being killed by the immune system.
This understanding has provided rationale for testing the combination of checkpoint inhibitors with SRS. Clinical trials testing this combination in other tumor types have shown preliminary evidence of enhanced activity against the tumor compared with SRS alone or a checkpoint inhibitor alone. More recently, researchers at Johns Hopkins University showed that this combination reduces tumor growth and improves survival in a mouse model of chordoma. Taken together, this evidence provides strong rationale for a clinical trial testing nivolumab alone and in combination with SRS.
Who can participate
This study is designed specifically for chordoma patients whose tumors have come back in the same area or have spread to other parts of the body. Patients must meet the following basic criteria to be eligible:
- Confirmed diagnosis of chordoma
- Recurrent or When tumors have spread to other parts of the body from the original tumor site. confirmed by imaging (cannot be newly diagnosed, primary chordoma)
- Age 15 years or older
- No major laboratory abnormalities
- No prior use of an anti-PD-1, anti-PD-L1, or anti-PD-L2 antibody
- Eligible to receive radiation to site of tumor or When tumors have spread to other parts of the body from the original tumor site.
- Willing and able to travel to the study site (Baltimore or New York) for all treatment and follow-up visits
Full eligibility criteria can be found on ClinicalTrials.gov.
How the trial will work
- Participants are assigned to one of two treatment groups. You will have a 50/50 chance (like flipping a coin) of being assigned to either treatment group:
- Participants assigned to the first group will receive nivolumab by Any fluids given inside a vein. These could be treatment, medications, blood, or contrast dye for MRI and CT scans. over 30 minutes on day 1, and again every 2 weeks for about 4 months (8 doses). Beginning with dose 9, participants will receive nivolumab every 4 weeks at a higher dose. Patients can remain on the trial up to 2 years, or until there is disease progression or unacceptable side effects are experienced.
- Participants assigned to the second group will receive the same schedule of nivolumab treatments, plus stereotactic radiosurgery treatment on day 8.
- A check-up exam will be performed every at each visit, before participants receive the scheduled nivolumab treatments.
- Participants will be evaluated for side effects for 100 days after stopping treatment. MRIs will be performed approximately every 10 weeks for 2 years, as part of standard follow-up.
- All exams, treatments, and evaluations are provided at the trial site where the patient enrolled in the study. Participants not local to the trial sites MUST be willing and able to travel to their trial site for all visits required by the trial.
