GammaCan Announces Positive Testing Results in the Development of VitiGam(TM) for the Treatment of Melanoma

  
    
  
  
    
      GammaCan International, Inc. (“GammaCan” 
      or “the Company”) (OTCBB: 
      GCAN), a developer of proprietary immunotherapies for the treatment of 
      melanoma and other cancers, today announced progress in its VitiGam™ 
      development program. During the last several months, the Company 
      has completed a series of significant animal experiments confirming the 
      effectiveness of IgG preparations derived from vitiligo donors against 
      melanoma cells. This is the basis for GammaCan’s 
      lead product, VitiGam™.
    
    
      In a number of human melanoma model experiments, using SCID mice and the 
      A375 human melanoma cell line, the Company demonstrated that 
      vitiligo-derived IgG preparations can prevent, in a statistically 
      significant manner, the growth of subcutaneous melanomas (tumors). In 
      these experiments, IgG preparations derived from vitiligo donors were 
      compared to a variety of other IgG preparations and also compared to 
      saline. These experiments further demonstrate that IgG preparations 
      derived from vitiligo donors also achieved, in a highly statistically 
      significant manner, a reduction in the tumor size of small tumors.
    
    
      Steven Katz, Chairman of the Board and President of GammaCan said, “Our 
      data are highly encouraging in that they demonstrate, for the first 
      time, in human melanoma models, anti-melanoma activity from IgG 
      preparations derived from vitiligo donors.” 
      Mr. Katz further commented that, “These 
      positive results keep us on track to file our IND with the U.S. Food and 
      Drug Administration in the near term.”
    
    
      About GammaCan
    
    
      GammaCan develops proprietary immunotherapy and related approaches to 
      treat melanoma and other cancers. GammaCan's patented platform 
      technology is based on the use of IgGs (gamma-immunoglobulins), a safe, 
      relatively non-toxic human plasma-derived product used to treat a 
      variety of immune deficiencies and autoimmune diseases. In cancer, 
      IgG-based therapies work by strengthening the patient's immune system. 
      Many experts currently view immunotherapy as a future alternative to 
      chemotherapy. The Company's lead drug candidate, VitiGam™, 
      targets Stage III and Stage IV melanoma for which no effective treatment 
      currently exists. In August 2007, VitiGam™ 
      received Orphan Drug designation from the U.S. Food and Drug 
      Administration (FDA) for the treatment of Stage IIB to Stage IV 
      metastatic melanoma. For more information about GammaCan, visit www.GammaCan.com.
    
    
      About VitiGam™
    
    
      VitiGam™ is a first-in-class IgG-based 
      anti-cancer immunotherapy being developed for the treatment of Stage III 
      and Stage IV melanoma. GammaCan is planning to submit its 
      Investigational New Drug Application (IND) for VitiGam™ 
      to the FDA in the near future. The Company expects to commence human 
      clinical trials shortly thereafter. VitiGam™ 
      is an IgG-based product manufactured from the plasma of donors with 
      Vitiligo, a benign skin condition affecting up to 2% of the general 
      population. Studies have shown that this "enriched" IgG formulation 
      contains potent anti-melanoma activity. Based on these studies, GammaCan 
      expects VitiGam™ to provide specific 
      anti-melanoma activity against melanoma cells, as well as non-specific 
      anti-cancer activity.
    
    
      About Melanoma
    
    
      Melanoma is a deadly form of skin cancer. According to the American 
      Cancer Society, melanoma accounts for approximately 4% of all skin 
      cancers but causes approximately 75% of all skin cancer-related deaths. 
      An estimated 62,000 people were diagnosed with and nearly 8,000 people 
      died from melanoma in the U.S. alone in 2007. If rapidly diagnosed and 
      surgically removed, early-stage melanoma is usually curable. However, 
      for patients with metastatic melanoma (Stage III and Stage IV), the 
      prognosis is poor since no effective treatment currently exists. These 
      patients have a median survival time of 8.5 months and a 5-year survival 
      rate of less than 10%. There has been little change in these results for 
      in excess of 25 years. The incidence of melanoma has increased more 
      rapidly than any other cancer during the past 10 years. The last drug to 
      treat patients with metastatic melanoma was approved by the FDA over 30 
      years ago.
    
    
      Safe Harbor Statement
    
    
      Statements in this press release that are not purely historical are 
      forward-looking statements. Forward-looking statements in this press 
      release include statements regarding: the commercialization of 
      anti-cancer immunotherapies and the Company's efforts to develop 
      therapies to boost the immune systems of cancer patients by the use of 
      IgG-based therapy. Actual outcomes and the Company's actual results 
      could differ materially from those in such forward-looking statements. 
      Factors that could cause actual results to differ materially include 
      risks and uncertainties such as the inability to finance the planned 
      development of the technology; the inability to hire appropriate staff 
      to develop the technology; unforeseen technical difficulties in 
      developing the technology; the inability to obtain regulatory approval 
      for human use; competitors' therapies proving to be more effective, 
      cheaper or otherwise preferable for consumers; the inability to market a 
      product; all of which could, among other things, delay or prevent 
      product release, as well as other factors expressed from time to time in
