Dose-escalation by Hypofractionated Stereotactic Radiotherapy for Brain Metastases in Non Small Cell Lung Cancer

Study Purpose

The objective of this trial is to assess the safety and feasibility of delivering SBRT to patients with limited BMs (less than 10 lesions of lung cancer) by establishing the maximally tolerated dose (MTD) of SABR in 5 fractions.

Recruitment Criteria

Accepts Healthy Volunteers

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

No
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.

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, 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.

NCT05588206
Phase

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.

Arms & Interventions

Arms

Experimental: Hypofractionated Stereotactic Radiotherapy for Brain Metastases

Interventions

Radiation: - Hypofractionated Stereotactic Radiotherap

A standard 3+3 statistical design was employed. Three patients will initially be treated at dose level 1, 6 Gy in 5 fractions, 3 fractions a week. Dose limiting toxicities (DLT) were defined as any grade 3-5 radiation injury or any non-hematologic toxicity felt to be possibly, probably, or definitely related to radiation, identified within the evaluation period of 3 months following the completion of radiotherapy.
