Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 100 years
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Cytologic proof of malignancy
  • Radiographic evidence of bone metastases
  • Intractable pain uncontrolled by opioids, medical management, injections/ablation or surgical intervention that would be difficult to address with conventional radiation therapy or other standard options and is limiting the patient's function and quality of life. Intractable pain will be defined as a visual analogue score of at least 4.
  • Definitive radiographic progression of osseous and/or visceral metastases on standard staging scans (CT, MRI, bone scan, PET scan or any other standard of care imaging) performed within the last 3 months in spite of standard oncologic interventions and/or inability to tolerate standard oncologic interventions
  • Life expectancy at least 4 weeks
  • Age≥ 18 years
Show all 9Show fewer
  • Patients of childbearing potential (male or female) must practice adequate contraception due to possible harmful effects of radiation therapy on an unborn child
  • Patient must have the ability to understand and the willingness to sign a written informed consent document
  • All patients must be informed of the investigational nature of this study and must be given written informed consent in accordance with institutional and federal guidelines

Who cannot join

  • Prior brain radiation
  • Patients must not have a serious medical or psychiatric illness that would, in the opinion of the treating physician prevent informed consent or completion of protocol treatment
  • Isolated localized pain amenable to focal radiation therapy, or pain well controlled by opioids, medical management, injections/ablation or surgical intervention
  • Malignancies being managed with curative intent
  • Life expectancy <4 weeks
  • The tumor amenable to curative management

About this study

Official title: A Pilot Study of Stereotactic Radiosurgical Hypophysectomy for Intractable Pain From Bone Metastases

This research is being done to see if a delivery of a single high dose of radiation therapy to a small area of the pituitary gland and pituitary stalk in a highly precise manner may be helpful in reducing intractable pain from bone metastases.

Read the detailed description

Although not currently standard of care, small series suggest both safety and efficacy of radiosurgical hypophysectomy in reducing cancer pain from bone metastases. In spite of the demonstrated feasibility in meeting normal tissue constraints and preliminary data suggestive of both safety and efficacy, radiosurgical hypophysectomy is rarely performed in clinical practice, and many radiation oncologists are not even aware of its potential to reduce intractable cancer pain. This is likely because, to date, well-designed prospective studies have not been performed to further explore both the safety and efficacy of the intervention. This single arm pilot study is designed to fill that void. If successful, the investigators plan to utilize the data to support the proposal of a larger scale follow-up clinical trial.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • radiosurgical hypophysectomyRadiation

    Patients will be treated to a dose of 150 Gy in a single fraction. All patients will undergo CT simulation with 1 mm slices as well as MRI simulation including at least high resolution 1 mm slice T1 weighted MRI. They will be treated in a supine position using an aquaplast mask system for immobilization.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in Intensity of Bone Pain

    To estimate the rate of clinically meaningful decrease in diffuse osseous pain following radiosurgical hypophysectomy at 4 weeks following completion of radiosurgical hypophysectomy. Score range 0-10, higher score worse pain. A 2 point reduction in the worst pain severity score on the Brief Pain Index (ie: question number 3) at 4 weeks following completion of radiosurgical hypophysectomy compared to baseline will be considered as clinically meaningful decrease.

    Measured: Post treatment day 10

Secondary outcomes (3)
  1. Participants With Reduction in Opioid Utilization Following Radiosurgical Hypophysectomy

    To estimate the rate of reduction in opioid utilization following radiosurgical hypophysectomy

    Measured: Approximately 28 weeks following completion of radiosurgical hypophysectomy

  2. Participants With Radiation Induced Optic Neuropathy Following Radiosurgical Hypophysectomy

    To estimate the risk of radiation induced optic neuropathy following radiosurgical hypophysectomy

    Measured: Approximately 28 weeks following completion of radiosurgical hypophysectomy

  3. Participants With Radiation-associated Acute and Long Term Neurologic Toxicity

    To estimate the radiation-associated acute and long term neurologic toxicity of radiosurgical hypophysectomy

    Measured: Approximately 28 weeks following completion of radiosurgical hypophysectomy

Questions about this trial

What is this clinical trial studying?

A study testing radiosurgical hypophysectomy in people with Bone Metastases, run by Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins 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 9 inclusion and 6 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: stopped early, as of the sponsor's last update on 17 Sep 2026. 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.

Are results available for this study?

Yes. Results are posted in the registry (first posted 16 Sep 2026). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in Intensity of Bone Pain (time frame: Post treatment day 10). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 17 Sep 2026.
