A Study of BIO 300 and Thoracic Radiation Therapy in People With Non-Small Cell Lung Cancer and Interstitial Lung Disease

A Phase II Study of BIO 300 to Reduce the Toxicity of Thoracic Radiotherapy for Patients With Early-Stage Non-Small Cell Lung Cancer and Interstitial Lung Disease (BREATHE)

Sponsor

Memorial Sloan Kettering Cancer Center

Enrollment

25 participants

Start Date

Jan 6, 2026

Study Type

INTERVENTIONAL

Conditions

NSCLC NSCLC Stage II NSCLC, Stage I

Summary

The purpose of this study to find out whether giving BIO 300 in combination with thoracic radiation therapy is effective in preventing pneumonitis in people with non-small cell lung cancer (NSCLC) and interstitial lung disease (ILD).

Eligibility

Min Age: 18 Years

Inclusion Criteria12

Capable of giving signed informed consent which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and in this protocol. - Patient age ≥ 18 at time of consent
Stage I - II NSCLC (as per the American Joint Commission on Cancer (AJCC) 8th edition)
° Pathologically proven diagnosis of cancer is strongly recommended but is not required if the risk of biopsy is unacceptable. If pathological evidence is not available, there must be clinical evidence for NSCLC and multidisciplinary consensus for treatment.
Interstitial Lung Disease diagnosis (one of the below)
ILD as diagnosed and managed by a pulmonologist
ILD based on diagnostic imaging criteria and abnormal DLCO
ILD as a result of connective tissue diseases (e.g., polymyositis/dermatomyositis, rheumatoid arthritis, systemic lupus erythematosus, Sjogren's syndrome, scleroderma, mixed connective tissue disease)
ECOG performance status of 0 - 3
Evidence of post-menopausal status or negative urinary or serum pregnancy test for female pre-menopausal patients. Women will be considered post-menopausal if they have been amenorrhoeic for 12 months without an alternative medical cause. The following age-specific requirements apply:
Women \<50 years of age would be considered post-menopausal if they have been amenorrhoeic for 12 months or more following cessation of exogenous hormonal treatments and if they have luteinizing hormone and follicle-stimulating hormone levels in the post-menopausal range for the institution or underwent surgical sterilization (bilateral oophorectomy or hysterectomy).
Women ≥50 years of age would be considered post-menopausal if they have been amenorrhoeic for 12 months or more following cessation of all exogenous hormonal treatments, had radiation-induced menopause with last menses \>1 year ago, had chemotherapy-induced menopause with last menses \>1 year ago, or underwent surgical sterilization (bilateral oophorectomy, bilateral salpingectomy or hysterectomy).
Life expectancy of at least 6 months

Exclusion Criteria14

Previous thoracic radiation
History of pneumonectomy
Major surgical procedure (e.g. intra-cranial, intra-thoracic, intra-abdominal, or intra-pelvic) within 28 days prior to enrollment.
Severe concurrent illness that may preclude timely completion of thoracic radiation or study procedures
Known allergy or hypersensitivity to any of the study drugs or any of the study drug excipients.
ILD exacerbation requiring hospitalization in the last 30 days
Poorly controlled cardiac arrhythmias not responding to medical therapy or a pacemaker
Female patients who are pregnant or breastfeeding or male or female patients of reproductive potential unless they are willing to employ a highly effective non-estrogen based contraception from screening to 30 days after the last dose of BIO 300 or to abstain from sexual intercourse during these time periods.
Effective method of non-estrogen-based contraception: condom and a diaphragm, condom and intrauterine device, condom and Depo-Provera, condom and Nexplanon, or condom and progesterone mini-pill
Women who have been off estrogen contraceptives for a minimum 5 days prior to the first scheduled day of study intervention dosing are eligible.
Concomitant medications:
Any investigational anticancer therapy.
Planned concurrent chemotherapy or immunotherapy
Biologic drugs targeting the immune system (e.g. TNFα blockers, anakinra, rituximab, abatacept, tocilizumab) planned to be use concurrently with BIO 300
