Pharmaceutical company Humanetics has developed a proprietary compound designed to protect healthy tissue from the damaging effects of radiation, such as from routine CT scans and x-rays.
Preclinical studies conducted through research grants from the U.S. National Institutes of Health and the U.S. Department of Health and Human Services show that the compound, BIO 300, protects healthy lung tissue from the harmful effects of ionizing radiation exposure, according to the company.
Humanetics plans to begin a clinical trial in the second quarter of 2015 to evaluate BIO 300's ability to reduce the side effects to normal tissue from chemotherapy and radiation associated with lung cancer treatment.
![Axial images from unenhanced calcium score cardiac CT (left) and curved planar reformation images from CT angiography (right) show that higher long-term exposure to air pollution is associated with greater coronary artery calcium and more obstructive coronary artery disease (CAD). Top row: Images in a 68-year-old male patient with higher 10-year mean ambient air pollution exposure (7.9 μg/m3 for particulate matter measuring ≤2.5 μm in diameter [PM2.5] and 17.4 parts per billion [ppb] for NO2) with extensive CAD (coronary artery calcium score [CACS] >1,000 and obstructive CAD [≥70% diameter stenosis]). Bottom row: Images in a 57-year-old female patient with lower 10-year mean ambient air pollution exposure (6.3 μg/m3 for PM2.5 and 4.6 ppb for NO2) with no CAD (CACS = 0 and no obstructive stenosis).](https://img.auntminnie.com/mindful/smg/workspaces/default/uploads/2026/06/hanneman.r6SMLzkezo.png?auto=format%2Ccompress&dpr=2&fit=crop&h=167&q=70&w=250)
