  8. Slide 8: First anticancer antibody therapeutic targeting DDR

    First anticancer antibody therapeutic targeting DDR • Deoxymabs are derived from an antibody, 3E10, which was isolated from a mouse model of the autoimmune disease lupus (SLE) • Deoxymabs bind to DNA and have a unique combination of properties: • Cancer seeking: tumors release DNA which attracts deo

  9. Slide 9: Patrys' deoxymab platform

    Patrys’ deoxymab platform • Patrys’ deoxymab platform is based on humanised versions of the mouse Mouse Humanised 3E10 antibodies • Global rights to 3E10 antibodies for the treatment of cancer were acquired in 2016 • Patrys has created humanised versions of the 3E10 antibodies for 3E10 - IgG PAT-DX3

  10. Slide 10: Deoxymab platform offers multiple therapeutic approaches

    Deoxymab platform offers multiple therapeutic approaches Single Agent Combination Therapies Targeted Therapies + • Many cancers have pre-existing defects • Radiation therapy and many chemo drugs • Deoxymabs can direct delivery of in their DNA damage repair (DDR) work by causing damage to DNA payload

  12. Slide 12: PAT-DX1 improves survival in glioblastoma

    PAT-DX1 improves survival in glioblastoma • Glioblastoma (GBM) is the most common form of primary brain cancer, with approximately 23,000 new cases diagnosed in the US each year Mice with human GBM • GBM is highly aggressive with few effective treatment options (5-year survival rate = 5.6%) • First

  13. Slide 13: PAT-DX1 improves survival with breast cancer metastases

    PAT-DX1 improves survival with breast cancer metastases • Approximately 230,000 women are diagnosed with breast cancer in the TNBC 1 Brain Metastases Model US each year • 10%-15% have Triple Negative Breast Cancer (TNBC), an aggressive form with deficiencies in the BRCA1 gene (DNA damage repair) • ~

  14. Slide 14: PAT-DX1 improves survival in pancreatic cancer

    PAT-DX1 improves survival in pancreatic cancer • Pancreatic ductal adenocarcinoma (PDAC) is one of the most common and aggressive cancer types, with a 5-year survival rate of 2–9%1 Pancreatic Cancer Model • Globally, 460k new cases and 432k deaths in 2018 100 Control • Limited treatment options 80 P

  15. Slide 15: PAT-DX3 development path has been initiated

    PAT-DX3 development path has been initiated • Full sized, IgG deoxymab antibody, PAT-DX3, produced in September 2020 • PAT-DX3 shares biological activity with PAT-DX1, but is differentiated and complementary • Different pharmacokinetic profile • Can cross the blood brain barrier in animal models of

  17. Slide 17: Combination therapies – improving glioblastoma treatments

    Combination therapies – improving glioblastoma treatments • Radiation is a mainstay treatment for glioblastoma (GBM) patients Radiation + PAT-DX1 improves survival and is used: • as a monotherapy (less frequently) • post-surgical removal of tumour tissue 71% • in combination with the drug temozolomi

  18. Slide 18: PAT-DX3 ADC proof of principle

    PAT-DX3 ADC proof of principle MCF7 Breast Cancer Model • Antibody drug conjugates are a fast-growing technology • Use antibody to target delivery of toxic payload to cancer cells. Often superior benefits to antibodies alone • Proof of principle study with PAT-DX3 conjugated to MMAE (payload used in
