BioLingus ^{Filed, US Offering, Removed, Nasdaq: SUBL}

We are an exempted company with limited liability incorporated under the laws of the Cayman Islands, which is structured as a holding company whose main business operations are conducted through our subsidiaries in Switzerland and to a lesser extent, HK SAR, the People’s Republic of China and Australia. We are a biotechnology company spearheading the development of oral (specifically, sublingual) delivery of peptides and proteins. Since our inception, we have focused on developing an alternative approach, known as sublingual delivery. The sublingual area lies under the tongue and is lined by a thin layer of cells which has a rich supply of blood vessels. Sublingual delivery has been successfully used commercially for many years to deliver a variety of so-called small molecule drugs, such as glyceryl trinitrate and ondansetron, which can readily penetrate this layer of cells to rapidly enter the blood stream. We hypothesized that we could similarly exploit the unique nature of the sublingual area to effectively deliver peptides and proteins, and this subsequently became the focus of our research. The main peptide used to improve the technology was exenatide, which was the first commercial glucagon-like peptide (GLP-1) receptor protein product and is routinely used to treat type 2 diabetes.
