Competing Interests

The ST266 therapy studied here is proprietary property of Noveome Biotherapeutics, Inc. I, Kenneth Shindler, corresponding author for this manuscript, have previously received honoraria from and served on Scientific Advisory Boards from Noveome, and have received sponsored research funding from Noveome for other projects in the past, with no current funding. For the in vivo studies described in the current manuscript, Noveome provided ST266 to my lab at no cost, but funding for all other study materials and personnel was provided by grants from NIH and non-profit foundations. The manuscript does also include in vitro cell assay data from experiments performed by our collaborators at Noveome. Co-authors (HW, ZK, JS, AE, LB) from Noveome were involved in design and completion of the in vitro studies, but all in vivo studies on optic neuritis, which represent the majority of experiments in this manuscript, were designed and conducted without influence from any of the Noveome employees to reduce any potential conflicts of interest. Neither I, nor any of my lab members (coauthors KW, RK, KD), have any financial stake in Noveome or ST266. These competing interests do not alter our adherence to PLOS ONE policies on sharing data and materials.
