4. Ibogaine HCl pharmaceutical grade 99.4% purity

5. 1973: Non A, Non B hepatitis is described 1989: HCV RNA virus identified 1990: Anti HCV effects of ibogaine reported 2005: Patent application for ibogaine to treat chronic HCV filed Hepatitis C (HCV) timeline

6. Most common viral infection in the United States New infections per year 1990 - 242,000 New infections per year 2001 - 25,000 New infections per year 2004 - 25,000 Greater than 75% of IVDUs test positive HCV infection

7. 1.The discovery of ibogaine’s use in treating both chemical dependence and HCV was by ibogaine activist advocates who were themselves treated or self-treated with ibogaine. 2.Scientific research followed patent development in the treatment of chemical dependence and it is hoped the same will be true for ibogaine related HCV research. Science follows patent development

15. HCV patent application

16. Example 1 Report A thirty-three year old male diagnosed with HCV and using 1/4 gram of heroin a day was administered 25 mg/kg ibogaine HCl. Following administration of ibogaine heroin use ceased along with swelling of the liver and pain in the area of the liver.

17. Example 2 Liver enzyme values reduced by 14 mg/kg ibogaine EnzymePrePost ALT41050 AST20125 GGT15533

18. Example 3 A sixty year old male testing positive for HCV RNA genotype I, administered the following dose regimens of ibogaine HCl. Subject weighed 79 kg. Doses administered were as total doses and not mg/kg. Day 1: 10 mg, Day 2: 20 mg, Day 3: 20 mg, Day 4: 30 mg, Day 5: 50 mg, Day 6: 75 mg, Day 8: 100 mg.Day 10: 150 mg, Day 14: 300 mg. HCV RNA UL/ml was reduced from 780,000 to 644,000, Pretreatment Alkaline Phosphatase was 99, AST was 103 and ALT 195. Post treatment Alkaline Phosphatase was 88, AST 89 and ALT 127. An additional 250 mg ibogaine HCl reduced HCV RNA UL/ml to 154,000. Further testing showed continued reduction to HCV RNA UL/ml 78,200

19. Example. 4 A forty-two year old female testing positive for HCV RNA type 3. RNA IU/ml was 12,600,000. Subject was administered a total of 27 mg/kg ibogaine HCl in the following regimen: 6 x 2 mg/kg 1 x 12 mg/kg 1 x 3 mg/kg HCV RNA IU/ml was reduced to 50,100. Prior to ibogaine treatment patient’s urine was dark and stool light. Post treatment color of urine and stool returned to normal.

20. Review Preliminary Examples Reporting Reduction Viral Load by ibogaine SubjectPrePost 3780,00078,200 412,600,0050,100

21. Encouraging results 1.Repetitive low dosing with ibogaine provided continuous depression of viral load. 2.Genotype 3 appears highly responsive in keeping with results of interferon riboviron therapy. 3.Continued reduction in viral load after stopping of ibogaine therapy observed. 4.Less toxic than current HCV therapies.

22. Future development 1.Interest of pharmaceutical companies with experience in development of HCV drugs. 2.Preclinical confirmation of efficacy if possible. 3.Phase I/II clinical studies to confirm findings and establish preferred dose regimen.
