Study summary

Metastatic malignant tumors comprise the vast majority of spinal tumors in adults. The most devastating complication of spinal metastatic disease (SMD) is invasion of the spinal canal and compression of the spinal cord or the nerve roots of the cauda equina, resulting in a clinical entity known as cord compression that manifests with progressive loss of motor function and sensation in the legs, as well as bladder and bowel incontinence.

The treatment of spinal metastases is mostly palliative with the goals of improving or maintaining neurologic function, achieving local tumor control, and spinal stability. Most patients with spinal metastatic disease are currently treated effectively with radiation therapy and/or surgery with good results. There are however certain limitations in the current treatment of SMD. Radiation therapy has two important limitations: 1) if the targeted SMD is in close proximity the spinal cord, delivery of high radiation doses is contraindicated as it may cause radiation-induced damage to the spinal cord (myelopathy, and 2) there is limit on the cumulative amount of radiation dose, which means that recurrent tumors may not be amenable to repeat radiation therapy. As far spinal surgery is concerned, the main limitation is that some patients are not fit for surgery because of medical co-morbidities.

This phase I clinical research trial will test the hypothesis that a new minimally invasive treatment called spinal intra-arterial chemotherapy (SIAC) can be safely applied in patients with SMD.

Read the detailed description

To date, there is no effective systemic therapy for spinal metastases, and the goal of treatment is to achieve local control of the tumor. Despite advances in radiation therapy, there is still a subgroup of patients that cannot be effectively treated with radiation because of close proximity of the tumor to the spinal cord. In addition, in cases of recurrent tumors, some patients cannot be re-treated because they reached the maximum allowed radiation dose. Surgery is the alternative treatment for these patients, but some tumors do recur after surgery while some patients have comorbidities that make surgery a high-risk procedure.

Based on our prior experience with selective IA chemotherapy for the treatment of ocular retinoblastoma and the high local control rates achieved with selective IA injection of chemotherapy in recurrent limb melanoma (limb infusion and limb perfusion) we expect that spinal intra-arterial chemotherapy with selective injection of Melphalan in the arteries feeding the metastatic disease is feasible and safe and may prove beneficial in achieving local control of the spinal tumor, preventing neurological compromise from cord compression. This minimally invasive approach can be used in patients in whom radiation therapy and surgery are contra-indicated and essentially have no other treatment options.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Patients with diseases to the spine causing cord compression grades 1, and 2 who are not candidates for the standard treatment of radiation therapy or surgery.
  • Patients older than 18 years old.
  • Patients able to give .

Exclusion criteria

Exclusion Criteria:

  • MRI findings of grade 3 epidural cord compression.
  • Rapidly worsening neurological symptoms.
  • The vascular supply to the spinal cord (anterior and/or posterior spinal arteries) originates from the same segmental arteries (intercostal or lumbar arteries) supplying the tumor.
  • less than 3 months.
  • Pregnant or lactating patients.
  • Female patients with inadequate .
  • History of severe allergy to contrast media.
  • Renal insufficiency (Creatinine >1.5mg/dL)
  • WBC \< 3000 cells/ mm3
  • \< 75000 cells/ mm3
Terms in these criteria, in plain language(5)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Metastases

Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

Study arms

  • Experimental
    Selective intra-arterial chemotherapy

    Subjects recruited to this study will receive intra-arterial injections of chemotherapy (melphalan) in the branches of the arteries feeding the metastatic spinal tumor. Subjects will receive general anesthesia or conscious sedation. A catheter will be guided using X-ray from the femoral artery at the top of the leg to the arteries of the spine. A dye will be injected through the catheter to show the arteries in greater detail. The chemotherapy is then injected into the tumor. We will inject the maximum systemic dose adjusted to white blood count and platelet count. Subjects will undergo three cycles of chemotherapy three to six weeks apart.

    Drug: Melphalan (intra-arterial infusion)

Interventions

  • Patients will undergo a minimally invasive procedure called spinal angiography. This procedure will identify the arteries feeding the tumor causing cord compression and will determine whether chemotherapy can be safely infused. The chemotherapy will be infused via a tiny soft plastic tube (called "microcatheter") at the tumor site over approximately 30 minutes. The drug of choice is melphalan (trade name Alkeran) at a maximum dose of 16mg/m2, adjusted for white cell count, platelet count and renal function. We will perform up to three intra-arterial chemotherapy treatments in 3-6 week intervals, based on the results of complete blood counts.

    Also known as: Alkeran

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 3, 2020, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
