SABR-ATAC: A Trial of TGF-beta Inhibition and Stereotactic Ablative Radiotherapy for Early Stage Non-small Cell Lung Cancer
United States28 participantsStarted 2016-08
Plain-language summary
The SABR-ATAC trial (Stereotactic Ablative Radiotherapy and anti-TGFB Antibody Combination) is a phase I/II trial that studies the side effects and efficacy of fresolimumab, an anti-transforming growth factor beta (TGFB) antibody, when given with stereotactic ablative radiotherapy in patients with stage IA-IB non-small cell lung cancer. Fresolimumab may inhibit radiation side effects and block tumor growth through multiple mechanisms. Stereotactic ablative radiotherapy (SABR), also known as stereotactic body radiotherapy (SBRT), is a specialized form of radiation therapy that precisely delivers high dose radiation directly to tumors, thus killing tumor cells and minimizing damage to normal tissue. Giving fresolimumab with SABR may work better in treating patients with early stage non-small cell lung cancer than treating with SABR alone.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Newly diagnosed, histologically proven (or strongly suspected, see below) T1-T2aN0M0 (Stage IA-IB) non-small cell lung cancer (NSCLC), with maximum tumor diameter =\< 5 cm under consideration for stereotactic ablative body radiotherapy (SABR) as definitive primary treatment
* Patient judged to be inoperable or at high surgical risk by a board qualified thoracic cancer surgeon who has evaluated the subject within the prior 12 weeks, or the patient's case has been discussed at a multidisciplinary tumor board with a thoracic cancer surgeon in attendance, or a patient who refuses surgery or declines to be evaluated for surgery.
* Able to give informed consent
* Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0 to 2
* Men or women of child bearing potential must agree to use an acceptable method of birth control (hormonal or barrier method of birth control; abstinence) to avoid pregnancy for at least 90 days after last study treatment (radiation or fresolimumab)
Exclusion Criteria:
* Significant anemia (hemoglobin below 9.0 g/dL) or neutropenia (absolute neutrophil count \[ANC\] \< 1000/mm\^3)
* Prior history of multifocal adenocarcinoma in situ (ie, classic or pure bronchioloalveolar carcinoma)
* Prior history of keratoacanthoma (well differentiated squamous cell skin cancer variant, often centrally ulcerated); history of basal cell cancer is allowed
* Pre malignant skin lesion(s) noted on prescreening skin exam, except for actinic (sola…
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
