  3. BioCancell Overview Incorporated in Delaware (July 2004), 17 Employees Developing innovative targeted drugs for the treatment of cancer, based on Professor Hochberg’s research Lead product candidate BC-819 in advanced clinical trials: Phase IIb in bladder cancer, Phase I/IIa in pancreatic and ovarian cancers Intellectual Property: 7 patent families Listed on TASE (BICL) in Aug. 2006, SEC filing since June 2009 Fundraising: $14.5M, in private placements and IPO on TASE (TASE:BICL), grants: CSO ($1.8M) and BIRDF ($0.95M) Major Stockholders: Clal Biotechnology Industries Ltd. (23.44%), Prof. Avraham Hochberg (13.09%), Tikcro (5.51%), Avi Barak (4.70%), Provident Fund of the Employees of the Hebrew University of Jerusalem Ltd. (3.99%)

  4. Technology Platform Targeted treatment platform based on the H19 gene H19 is a significant differentiator - expressed uniquely within cancer cells while not expressed in normal cells BC-819 drug candidate use the H19 gene to activate the diphtheria toxin in cancer cells, which destroys the cancer cells, without affecting normal cells The treatment is patient oriented and targeted without side effects* Platform potential: H19 expressed in more than 40 different cancer indications *Detected to date

  5. After birth, H19 is expressed only in cancer cells, and is therefore a significant marker of cancer cells The expression of H19 in cancer cells promote tumor development

  6. Diphtheria Toxin sequence H19 Promoter A DNA plasmid containing the H19 gene regulatory sequences that drive the expression of the Diphtheria Toxin A gene (DTA-H19) The Drug - BC-819 Plasmid

  7. The Advantages of BC-819 • Good safety profile– no side effects related to the drug* • Lack of side effects – prevents patient withdrawal (compared to chemotherapy treatment) • Reduces Multi-Drug Resistance (MDR) - a major disadvantage of chemotherapy • Targeted drug - yields superior success rate • Expected fast regulatory pathway (Fast-Track) - as FDA aims to promote new cancer treatments • Same drug for 40 different cancer types expressing H19 • Low cost manufacturing vs. other biological products *Detected to date

  8. BC-819 Development Roadmap All Indications are with Fast-Track Potential 2009 2010 2011 2012 PhaseI/IIa (was completed in 2007) Phase IIb Bladder cancer FDA Meeting Phase III Phase I/IIa Ovarian cancer Phase IIb FDA Meeting Phase III Phase I/IIa Pancreatic cancer Phase IIb FDA Meeting Phase III

  9. Market Size – Treatment of Bladder Cancer The cost per patient of bladder cancer from diagnosis to death is the highest of all cancers, ranging from $96K-$187K * Data: Globocan; World Population Prospects and American Cancer Society, estimated 2009. Data refers to the population in the 7 major pharmaceutical markets ** % of patients expressing H19 • Competitors’ Drugs – Annual Sales Volume: • BCG* (TheraCys/ TICE) – Sanofi-Aventis/ Schering-Plough Corp. (Organon Pharmaceuticals), $200M * Drug label present black box warning

  10. Market Size – Treatment of Ovarian Cancer * Data: Globocan; World Population Prospects and American Cancer Society, estimated 2009. Data refers to the population in the 7 major pharmaceutical markets ** % of patients expressing H19 • Competitors’ Drugs – Annual Sales Volume: • Doxil/ Caelyx* - Johnson & Johnson/ Schering-Plough • Corp, $650M (all indications) • Taxotere* (Sanofi-Aventis), $3B (all indications) • Hycamitin  (GlaxoSmithKline), $325M (all indications) * Drug label present black box warning

  11. Market Size – Treatment of Pancreatic Cancer * Data: Globocan; World Population Prospects and American Cancer Society, estimated 2009. Data refers to the population in the 7 major pharmaceutical markets ** % of patients expressing H19 • Competitors’ Drugs – Annual Sales Volume: • Gemzar - Eli Lilly & Co, $1.72B (all indications) • Tarceva (in combination with Gemzar) – OSI Pharmaceuticals /Genentech/Roche, $1.66B (all indications)

  12. Marketed Blockbuster Drugs - Sales Avastin – originally approved for colorectal cancer Lung (NSCLC) RCC/EMEA HER2- negative breast cancer (new approved indications, contributed to an increase in sales) Herceptin - breast cancer, for “only” 40,000 potential patients * Source: Data Monitor

  13. BC-819 – Additional Indications • BC-819 has been successfully tested in animals for the treatment of lung cancer, liver cancer and kidney cancer • Market potential (annual sales) for other drugs in those indications: • Lung Cancer (NSCLC): Tarceva (Erlotinib) - $1.66B • Liver Cancer: 5-Fluorouracil (Adrucil, Efudex, Fluoroplex) – Blockbuster • Kidney Cancer(RCC): Sorafenib(Nexavar) - $900M

  14. Phase I/IIa in Bladder Cancer Purpose - assess the safety and preliminary efficacy of BC-819 Performed at two medical centers in Israel 18patients participated in the trial, who had failed treatment with standard treatments (BCG or chemotherapy) The trial was successfully concluded in August 2007 Results: - No Serious Adverse Events related to BC-819 were detected - 55.6% (10/18 patients) did not experience recurrence of tumor - 94.4% (17/18 patients) did not experience progression

  15. Phase IIb in Bladder Cancer • Purpose – two stage design clinical study to assess the efficacy and safety of BC-819 • Performed at seven medical centers in Israel and one in the US (BCG Oncology, Arizona) • Inclusion criteria - Refractorypatients with TCC (recurrent stages Ta, T1, low grade) that is positive for H19, who have failed treatment with BCG or chemotherapy • Eligible patients will receive a six-week induction course of once-weekly intravesical administrations • 33 patients will participate: At least 5 of first 18 evaluable patients must have a CR to meet the criteria to continue accrual of 15 additional evaluable patients
