We expect to close our “D” round of funding with sophisticated and well recognized US and international investors.  It is likely that we will enter into further financing in late 2023/early 2024 which would lead to an initial public offering, assuming the capital markets can support such efforts. To-date, we have closed three significant venture capital financings amounting to approximately $45M.  Arthrosi has a passionate and seasoned team, guided by experienced leaders in developing products for gout and other therapeutic areas.  Our team is based primarily in San Diego, California and a portion of our management team is based in in other areas of the country.   We are a very small but growing team with a bright future.
