The goal of the biomarker-focused study was to test the relationship between NP001 macrophage-targeted immune regulation and the theory that microbial translocation contributed to ALS progression.
“The current study links the regulation of the innate immune system by NP001 with ALS disease modification.” – McGrath, MD, PhD Published in the journal ‘Biomedicines', the peer-reviewed study shows a clear relationship between microbial translocation, inflammation, and disease pathogenesis. Microbial translocation is a process that occurs when bacteria from the gut break through the epithelial barrier and leak into the bloodstream. This initiates a self-perpetuating cycle of inflammation now shown to be directly related to the pathogenesis of ALS and potentially other diseases. NP001 treatment has been shown to restore the normal process of resolution in the inflammatory cycle and in so doing, restore the integrity of the epithelial barrier in the gut – halting damaging microbial translocation. In this study, the immunoregulatory activity of NP001 treatment has been confirmed via the normalization of key blood biomarkers. Mechanism of Action “We have long-postulated that NP001, as a regulator of the innate immune system, restores the balance between macrophages that initiate inflammation and those that promote wound healing,” said Michael McGrath, MD, PhD, CSO Neuvivo and Professor Emeritus of Medicine, UCSF. “The current study links the regulation of the innate immune system by NP001 with ALS disease modification, an approach potentially applicable to other inflammatory diseases. ALS was traditionally considered to affect primarily the central nervous system, but recent research supports what we have postulated – that ALS originates as a systemic immunologic reaction to abnormally processed proteins within neurons, ultimately leading to their dysfunction and death.” Study Details Earlier in 2022, NP001’s activity in two placebo-controlled, 6-month Phase 2 ALS trials was reported. The post hoc analysis defined a large subset of patients between 40-65 years old and with slightly elevated baseline levels of inflammation who were clinically responsive to NP001 treatment. Data showed that NP001 administration was associated with a significantly greater retention of physical function in patients as measured by the ALSFRS-R scale and a significantly greater maintenance of respiratory function. The current study reported in Biomedicines started by defining groups of ALS patients from the Phase 2A NP001 clinical trial that had clear slowing of disease progression compared to controls. Blood biomarkers from the two groups were then measured to determine whether any changes over the 6-month study would be linked to a positive clinical outcome in drug treated patients as compared to controls. Biomarker Data Biomarker data showed that factors associated with harmful microbial translocation (LPS, LBP and HGF), monocyte trafficking (sCD163) and inflammasome activation (IL-18) were significantly decreased in NP001 recipients as compared to placebo over 6 months. Biomarker values that significantly increased were those associated with suppression of inflammation (IL-10, neopterin) and wound healing (EGF). Plasma levels for IL-6, IL-8 and TNF-α were within the normal ranges and relatively stable over the 6-month study. A total of 9 biomarkers showed notable changes in the blood of patients treated with NP001 as compared to controls, linking a slowing of ALS disease progression with the regulation of microbial translocation. Patient Subsets Biomedicines Publication – Open Access: Editor’s Note: The macrophage is the most primordial cell in the innate immune system. It is a type of white blood cell involved in the functioning of the inflammation-resolution cycle. Normally, in response to infection, a subset of macrophages become inflammatory and another subset become wound healing to maintain equilibrium. In ALS, the process is compromised, resulting in unchecked inflammation. Macrophage-targeted treatment restores the normal functioning in the epithelial barrier and throughout the body. About Neuvivo: Neuvivo is a private, late-clinical stage biopharmaceutical company developing advanced treatments for ALS and other neurodegenerative diseases. The company was formed by industry leaders and scientists, focused on improving the prognosis for patients diagnosed with ALS and a range of diseases for which few current treatment options exist. Lead candidate NP001 has been shown to be effective in a large subset of people living with ALS and has an exceptional safety profile. Neuvivo is working to make this treatment broadly available to patients as soon as possible. For more information please visit: www.Neuvivo.com Contact:
