Prostate Cancer
• Forms in male prostate gland
• Most common cancer in men
• Risk increases with age
•In 2012:
 241,740 men will be diagnosed
 25,170 will die from the disease
14
How Our Platform Works
•Ceramide levels increase during radiation therapy; leads to cancer cell death
•Acid ceramidase (AC) and Sphingosine Kinase (SK) activity increase during radiation
therapy in cancer cells
•AC reduces ceramide levels, SK forms S1P, both permitting cancer cell survival
•Our compounds inhibit AC or SK or mimic ceramide making radiation or other
therapies more effective at inducing cancer cell death
15
Progress and Leads
•Clinical efficacy established in animal models of cancer at nM concentrations
•Dose Escalation: No toxicity observed at effective doses and 20 X higher doses

Our Value Proposition
• Enhances Radiotherapy leading to more effective cancer
treatment
• Fewer side effects
Achieve same clinical benefit with reduced radiation
• Better quality of life
• Greater preservation of sexual function
• Reduce incidence of relapse = Reduced overall treatment
costs and reduced death rate
• Small Molecules = Easy manufacturing and delivery
23
More effective radiotherapy of
prostate cancer means:
• Same clinical benefit with reduced radiation
▫ Fewer side effects
▫ Greater preservation of sexual function and continence
issues
▫ Reduced incidence of relapse
▫ Targets mechanism of radioresistance
• Reduced death rates
24
Market opportunity
• United States: 241,740 cases/year
• Worldwide:
903,500 cases/year
• @50% of patients will receive IR therapy. 21-44%
of these patients will relapse. In a couple of
studies 50% of patients relapsed and 51% of them
had local disease (not metastatic) making local
control relevant to survival. Our preclinical
indication is that SPG105/IR therapy will reduce
relapse and improve survival.
25
Financial Assumptions and Forecast
• Based on annual estimated US prostate cancer cases
treated with radiation therapy
• Market penetration expected similar to other cancer
therapeutics
• No increase in cases, no relapses
• $8000 per treatment per patient (drug cost)
Estimated worldwide market projected in billions
26
Other Markets
Platform applicable to the majority of solid tumors and
any cancer for which patients receive radiation therapy,
including internal radiotherapy (brachytherapy).

Radiation Therapy for Other Cancers –
Candidates for SPG105
• Lung 60-70 Gy in 30-35 fractions
• Breast 50.4 - 60 Gy in 28-33 fractions
• Pancreas 50.4-54 Gy in 28-30 fractions
• Melanoma 36-60 Gy in 6-30 fractions (big variability)
• Head and Neck 60-70 Gy in 30-35 fractions.
Potential: If clinical trials successfully model the preclinical data then
SPG105 has the potential to become a standard of care
blockbuster drug in the radiation treatment industry.
29
Competing Radiosensitizer
Drugs
• The first annual workshop for preclinical and clinical development of radiosensitizers
took place at the NCI in August 2012 (JNCI, pages 1-8, 2012 advanced access).
• Summary:
• There are ongoing trials many of which are focused on biomarker indicators to
improve patient selection.
• A partial use of drugs being studied include standard chemotherapeutic drugs such
as Gemcitabine, 5-Fu, Cisplatin while others are kinase inhibitors such as; Erlotinib,
Bevacizumab as examples.
• Other categories of drugs include ER inhibitor Tamoxifen and Her-2 inhibitors like
Trastuzumab.
• Two potential drugs that inhibit aspects of the ceramide-S1P rheostat with an
unknown value in the radiation therapy domain include Fingolimod and ASONEP.
Both of these drugs act downstream of SPG105.
• A recent preclinical publication demonstrated rapamycin might be useful as a
radiosensitizer.
30
SPG105 is clean, unlike Gilenya which has multiple
effects (“dirty drug”):
It inhibits Acid Ceramidase by specifically targeting
acidic compartments (lysosomes) and functioning in
lysosomes to inhibit lysosomal enzyme.
Investigations have not found actions anywhere
else.
31
SPG105 can be used in resistance of different
therapies that involve ceramide pathway.
• Chemotherapy
• TKI targeted therapies
• HDACI therapies
• mAb therapies
32
Patent Position
• SphingoGene has filed broad patents around targets
and various classes of compounds which can affect
their targets
• Lead Compounds:
Worldwide Patent pending for SPG105 (clinical lead); US
2011/0251197 A1
Issued patent for SPG103; US8,093,393 B2
Patent pending for SPG104; US 2012/0035268 A1
