Posters – Immunology & Oncology NAME OF THE PROJECT NAME OF THE MAIN CONTACT ORGANISATION NAME LTVAX, a therapeutic vaccine for lung cancer treatment based on BacVac Laurent BUFFAT APCure APCure is a company developing immunotherapy products based on the BacVac technology, a safe, bioengineered, bacterial vector. LTVAX, the first BacVac-based product, is a therapeutic vaccine for the treatment of Merkel Cell Virus (MCV) positive lung cancers. It is a safe and effective vector, with a simple pharmaceutical development • Safe: This bacterial vector is devoid of toxins and unable to replicate once injected in the host. This makes the bacterial vector innocuous, easy to eliminate by the host and safe for the environment • Effective: LTVAX induces a strong immune response against the tumor by educating the Technology immune system to detect and kill tumor cells. LTVAX great efficacy relies on its ability to deliver tumor antigens to immune cells • Simple pharmaceutical development: the LTVAX product is a simple bacterial culture. Chemically defined medium and storage conditions have already been identified. APCure has shown that LTVAX reduces the growth of a tumor expressing MCV antigens in mice. Importantly, APCure has also demonstrated that LTVAX is synergistic with anti-PD1 antibody, the new reference in cancer treatment, in a pre-clinical model. LTVAX can potentially be combined with other immune checkpoint inhibitors (anti-CTLA4, …) or other therapeutic approaches (CAR-T, …) Customers / Target market LTvax induces an immune response against the Large-T (LT) antigen of the MCV, which is detected in many types of cancers, including the Merkel Cell Carcinoma (MCC) and 20 % of lung cancers. The first LTvax application will be the immunotherapy of MCV-positive lung cancer, with a potential market of 3 B€ per year in the USA and Europe. The same product will then find further application to other MCV-positive tumors, with an overall market estimated at 5 B€ per year in the USA and EU markets. LTvax is a first-in-class product. It is the first therapeutic vaccine targeting the Large-T (LT) antigen of the MCV. Industry and competitors Anti-PD1 monoclonal antibodies (nivolumab, pembrolizumab) are the new reference in lung cancer treatment. However, rather than a competitive approach, this new type of therapy is a great opportunity for therapeutic vaccines such as LTVAX. Indeed, therapies combining therapeutic vaccines and anti-PD1 antibodies are regarded as the future for efficient cancer treatments. LTVAX has a great potential in combinatory treatment with anti-PD1 antibody in clinic: LTVAX induces the immune response against the tumor, while the anti-PD1 makes the induced response strongly effective at the tumor site. APCure has already demonstrated that LTVAX is synergistic with anti-PD1 antibody. LTVAX : a 8M€ for a 200M€ return on investment Financing need / Commercial opportunity • APCure is seeking a 8 M€ investment : 1M€ for the pre-clinical phase, 2M€ for the Phase I clinical trial and 5M€ for the phase II clinical trial • LTVAX will be outlicensed in 2019 LTVAX outlicensing will generate a return on investment of ~200 M€ (excluding royalties) One VC is prepared to invest in a non-leader position • Secured intellectual property IP – Patent situation • APCure has filed a patent request to protect LTVAX intellectual property (EP15305861.5 (A1)) • LTVAX is based on a technology that is covered by two patent families in the USA and Europe. APCure has the exclusive license for these patents and a worldwide freedom to operate (EP1692162(B1) and EP2604682 (A1)) LTVAX product is ready to enter pre-clinical and pharmaceutical development. APCure is now looking for investors or co-development partners to perform the preclinical and clinical development of LTvax as a bitherapy strategy with immune checkpoint inhibitors. Future steps / Milestones LTvax development in the EU can be summarized into three Milestones with the following requirements: • Milestone 0 (LTvax preclinical validation): 1 M€, achieved Q1 of 2017 • Milestone 1 (phase I/IIa study for safety evaluation): 2 M€, achieved Q1 of 2018 • Milestone 2 (phase IIb study for efficacy evaluation): 5 M€, achieved Q3 of 2019 Further reading N/A Contact person Dr Laurent BUFFAT, CEO, APCure, laurent.buffat@apcure.com 1/2
