Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

Detailed Description

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: 2.1-4.0 cm diameter
Patients will undergo dose escalated five fraction stereotactic radiosurgery for diagnosed brain metastases. 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. Starting dose level 7 Gy x 5 fractions
Radiation: 7 Gy
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.
Radiation: 8 Gy
