BERKELEY, Calif., Jan. 8, 2018 /PRNewswire/ -- Bell Biosystems, Inc. (Bell) today presented the results of their latest pre-clinicalsafety study at the Biotech Showcase in San Francisco that runs concurrently with the annual J.P. Morgan Healthcare Conference. The study was designed in accordance with USP <151> pyrogenicity guidelines, where
Magnelle (magnetic organelle) contrast agents are being launched commercially this month, and create magnetic resonance imaging (MRI) beacons in a variety of cell therapies. Magnelle-powering(TM) of therapeutic cells has been shown in small animal studies to provide rich data on transplanted cell location and, unlike alternatives, on cell viability post-transplantation using non-invasive MRI. This is highly enabling for Cell Therapy research scientists and biopharmaceutical development organizations where measuring cell viability and durability post-injection has been challenging in the past, but is critical to translation and clinical realization of this class of therapeutic.
The Magnelle reagents are derived from non-pathogenic, Gram-negative bacteria inspired by the bacterial origin of natural organelles such as the mitochondria and chloroplast. Gram-negative bacteria express one of six types of endotoxin or lipopolysaccharide (LPS), which can potentially induce life threatening pyrogenic reactions depending on the detailed molecular structure of LPS isoforms. To assess this safety concern, Bell subcontracted Pacific BioLabs, Inc. to undertake the rabbit pyrogen study following USP <151>. The double-blinded study included three cohorts: Magnelle-powered hMSCs; unlabeled hMSCs; and injection fluid control. None of the test subjects receiving Magnelle-powered cells exhibited a temperature increase of more than 0.1oC, proving in vivo that the Magnelle expressed LPS is not pyrogenic. Note, USP <151> states that a temperature increase of 0.5oC or more constitutes failure of the test.
"We are extremely encouraged by the results of these latest safety assessments as a key step forward in the realization of this technology for labeling and tracking cellular therapies," stated Dr. Caleb B. Bell III Founder and CTO at Bell. With successful completion of rodent safety studies and this latest pyrogen assessment, the company will be undertaking large animal studies as the next step towards clinical uses.
Bell Biosystems, Inc. is a Bay Area-based, emerging biotech company commercializing in vivo tracking and contrast agent technologies for cell therapies. Our first product, the Magnelle® cell tracking solution, provides precise location and viability data for in vivo transplanted cells. We are positioning Magnelle-powered cell therapies to disrupt the regenerative medicine marketplace by providing actionable insights for therapeutic durability including therapeutic cell viability feedback and localization of transplanted cells. The first product will be commercialized in early 2018. Over the years, Bell has received support from Start-X (a Stanford-affiliated startup accelerator), Breakout Labs (a project of the Thiel Foundation), QB3 and J-Labs. Additionally, Bell Bio was recognized in 2014 by the White House as a "breakthrough life science technology platform;" the 2014 Rising Star Award from BayBio (now CLSA); and were sponsored by JETRO, Japan's Trade Organization, for an exclusive business-matching program in Hiroshima.
