Seite 44 des US-Börsengang von Adaptimmune
"Our TCR technology was originally developed by Avidex, and was subsequently acquired by Medigene in 2006. We were formed as a new, separate company and licensed our TCR technology for T-cell therapy from Medigene in July 2008. Immunocore was subsequently formed as a new separate company and licensed its TCR technology for soluble TCRs from Medigene later in 2008 to develop soluble TCR proteins. Immunocore currently owns approximately 7.6% of the equity interests in Adaptimmune. All of our ordinary shareholders and their affiliates with the exception of Dr. Tayton-Martin also hold shares of Immunocore. These ordinary shareholders and their affiliates own 97.1% of the equity interests in Immunocore and Immunocore and its shareholders and their affiliates own 51.1% of the equity interests in Adaptimmune. Until March 2014, our Chief Executive Officer, or CEO, was also the CEO of Immunocore and he is currently on the board of Immunocore. In addition, two of our directors, Ian Laing and Jonathan Knowles also serve on the board of Immunocore and two of our greater than 5% shareholders, Nicholas Cross and George Robinson, are significant shareholders in, and are directors of, Immunocore. Our scientific co-founder, Bent Jakobsen, is also an employee of Immunocore.
Both Adaptimmune and Immunocore focus on technologies that are based on TCR therapies. Each company focuses on distinct applications of, and utilizes different, TCRs. Immunocore uses soluble TCRs whereas Adaptimmune uses cellular TCR therapeutic candidates. Both soluble TCRs and Adaptimmune's TCR therapeutic candidates rely on the engineering of TCRs to create affinity-enhanced TCRs. In Adaptimmune's case, once the engineered affinity-enhanced TCR has been generated, the gene encoding that engineered TCR is transduced into patient T cells. With soluble TCRs, there is no transduction. For soluble TCRs, the engineered affinity-enhanced TCRs are combined with an antibody fragment, anti-CD3, and it is this combined TCR/anti-CD3 candidate that is then used to treat patients directly. The combined candidates are called ImmTACs. As a result, the end therapeutic candidates being developed by each company are different in terms of end structure, affinity, require different manufacturing and administration routes and are likely to have different properties in patients. For example, ImmTACs are not anticipated to persist beyond a few hours in a patient following administration, whereas Adaptimmune's TCR therapeutics have been shown to persist in patients for several months or more; ImmTACs are likely to require higher amounts of target peptide to be present and hence Adaptimmune's TCR therapeutics may address cancer cells with lower levels of antigen; ImmTACs rely on activating the patient's existing T cells through an anti-CD3-CD3 interaction, whereas Adaptimune's TCR therapeutic candidates activate T cells through direct binding to the target peptide and this results in a different mechanism of action being seen in in vitro tests.
Notwithstanding the differences between Immunocore's and Adaptimmune's end products, there is a risk that both companies could potentially develop products or therapies that target the same peptide and are directly competitive and/or address the same indications and patient populations. For example, both companies could develop therapeutic candidates to the same peptide target and hence have a product addressing the same patient populations in the same way as any other competing technology. In addition, both Immunocore and Adaptimmune have entered into collaboration agreements with GSK, which could decide over time to devote greater time and resources to Immunocore at the expense of Adaptimmune."
