A Dose Escalation Trial of Five Fraction Stereotactic Radiation Therapy for Brain Metastases

Study Purpose

This study looks at dose escalation for five fraction stereotactic radiotherapy for patients diagnosed with brain metastases with tumors 2.1-4.0 cm in diameter or 4.1-6.0 cm in diameter.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Eligible Ages 18 Years and Over
Gender All
More Inclusion & Exclusion Criteria

Inclusion Criteria:

  • - All patients must have histologically confirmed malignancy.
  • - All patients must have imaging suggestive of one or more brain metastases.
  • - Karnofsky performance status (KPS) ≥ 60.
  • - Age > 18 years.
  • - Patients must provide written informed consent to participate in the study.
  • - Patients must have less than or equal to 10 brain metastases as identified on brain MRI.

Exclusion Criteria:

  • - History of surgical resection to the tumor of interest.
  • - History of radiation to the tumor of interest.
  • - History of previous whole brain irradiation.
  • - Receipt of systemic therapy within one week of planned radiation treatment except for hormonal agents.
  • - Patient is unable to have MRI or MRI contrast.
  • - Inability to meet the appropriate normal tissue dose constraints secondary to tumor location should result in exclusion of the patient / tumor.
  • - Patients with a non-index tumor (second tumor) greater than 3 cm in diameter will be excluded.

Trial Details

Trial ID:

This trial id was obtained from, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.


Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Brain Metastases
Additional Details

This study looks at dose escalation treatment in patients diagnosed with brain metastases. Treatment involve five fraction stereotactic radiotherapy for patients with brain tumors 2.1-4.0 cm in diameter or 4.1-6.0 cm in diameter and dose escalation treatment is delivered only to the single largest tumor while all other tumors are treated with standard of care practices if they are present. A dose escalation schedule is proposed based on the monitoring of CNS toxicity and tumor size of the largest tumor, given it falls into the parameters set on diameter.

Arms & Interventions


Experimental: Dose Escalated 5 Fraction Stereotactic Radiosurgery

Patients will undergo dose escalated five fraction stereotactic radiosurgery for diagnosed brain metastases. Tumors must fall into one of two categories: 2.1-4.0cm diameter or 4.1-6.0 cm diameter. Only single largest tumor will be treated with dose escalation. All other tumors (if present) will be treated with standard of care five fraction stereotactic radiosurgery.


Radiation: - Dose Escalated Five Fraction Stereotactic Radiosurgery

As focal radiation techniques are utilized more frequently in the treatment of brain metastases, there is increasing need to accurately define the appropriate patient and tumor characteristics for focal therapy. Unfortunately, not all patients are good candidates for single fraction stereotactic radiosurgery (SRS) since large tumors and those in unfavorable locations have been associated with unacceptable rates of treatment-related toxicity. Five fraction stereotactic radiation has proven to be a more effective treatment for these patients that aren't good candidates.
