Mikhail Sitkovsky Skolkovo im modernization of medicine

  1. The “Cutting Edge” technologies
  2. The “Hellstrom” Paradox”, Natur e, 1968; ? Anti-tumor T cells destroy tumor cells in vitro : The “Hellstrom-Schreiber” Paradox: -“ Equilibrium lesions ”(Nature, 2007) The Motivation: 1974, Moscow University In vivo tumor seems to be protected :
  3. Adenosine puts anti-tumor T killer cells to sleep … The Solution Ohta and Sitkovsky, Nature 2001
  4. Tumor Defense Countermeasures
  5. Tumor Rejection Survival
  6. Tumor Rejection Anti-Tumor Hypoxia Drug Competitive A2AR Antagonist Tumor Hypoxia [O 2 ] Low Ecto-Enzymes [CD39] High [CD73] High ATP-->[Adenosine] High Elimination or Blockade of CD73
  7. Preclinical evidence of tumor rejection and immunological memory to rejected tumor due to the action of the A2AR antagonist in different animal models of cancer
  8. The Anti-Tumor Hypoxia Drug enables anti-tumor T killer cells to reject lung tumors 21% 40% 60%
  9. Some of the promising opportunities for Skolkovo Specific Examples…
  10. S22-Fc - a multi-specific binder to EGFR, Her3 and Her2/neu Binding to T6-17 (Her2) and NE91(EGFR) cells by S22-Fc MCF7 NE91 T6-17 S22-Fc S22 Fc
  11. “ Creation of a trivalent antibody like molecule with picomolar activity against EGFr, HER2/neu and HER3” The molecule is already fully “human” …; Has potential to help all HER+ breast cancer patients as compared with 25% for original herceptin Ab… as compared with Zero with no “old” herceptin. Is not it something that “ everybody wants and nobody has ”?
  12.

  14. Contacts USA numbers 617-669-88-16 - works in Moscow 617-800-52-65
  15. Molecular Weight hGH ~ 3000 atoms Factor VIII ~ 55,000 atoms Need for Trials Biosimilars – Complexity leads to unknowns - If you don’t run trials – you won’t know the safety or efficacy Aspirin 21 atoms Complexity of biotech products IgG Antibody ~ 25,000 atoms 0 200,000 350,000 250,000 50,000 150,000 100,000 300,000 COOH OCOCH 3
  16. Drug Discovery from Uncultur-able before Microorganisms ● 99% of all species of microorganisms on the planet do not grow in the lab ● Millions of new species, an enormous untapped resource for drug discovery ● A general method to grow uncultured microorganisms developed based on cultivation in situ in diffusion chamber and subsequent “domestication” for growth in the lab ● Growth factors for many uncultured species identified, an additional tool for growing them in the lab Patent: US 7,011,957 Kaeberlein et al., Science 296:1127-1129.
