ď Located Bridgewater, NJ
ď 9 employees
ď Focused on cancer therapeutics
ď Listed on OTC QB as SNTI
4. Senescoâs Gene Regulation
Platform Technology
ď Senesco Technologies is a clinical stage biotech company specializing
in cancer therapeutics
ď Our proprietary gene regulation technology has demonstrated the
ability to eliminate cancerous cells and protect healthy cells from
premature death
ď The company is running a Phase 1b/2a trial with a product that treats
B-cell cancers (which include multiple myelomia and non-Hodgkins Bcell lymphomas)
ď Trial sites include the Mayo Clinic and the Fred Hutchinson Cancer
Research Center
ď The technology was developed over the last 15 years through the
discovery that the genetic pathway for cell growth control, targeted by
Senesco, is common to both plants and humans

7. Senescoâs Platform Targets
B-cell Cancers
ď Multiple myeloma is an incurable cancer
of plasma cells â âB-cellâ cancer
ď§ ~65,000 patients in the US
ď§ Median survival time is 2½ to 5 years
ď Diffuse large B-cell lymphoma (DLBCL)
ď§ Most commonly diagnosed lymphoma
ď§ ~120,00 patients in the US
ď§ ~ 50% of patients unresponsive to standard
therapy
ď Mantle cell lymphoma (MCL)
All orphan drug indications

9. Turning on a Normal Regulatory
Process
ď Lysine Protein â need to turn up
ď§ Activates programmed cell death (apoptosis)
ď Hypusine Protein â need to turn down
ď§ Stimulates cell growth
ď Senescoâs drug reprograms the cells to
recognize the death message by modulating
the levels of both proteins

10. Proteins Regulate Cell Growth
and Death
These two proteins act as a biological
switch to promote cell death or survival

2. DNA plasmid makes stable death
message under control of B-cell
specific promoter
3. Polymer (PEI) forms nanoparticle
to protect RNA and DNA and
deliver death message to target

activity in most cancer cell lines tested in vitro
ď Efficacy in multiple in vivo disease models
including melanoma (B16-F0) and lung (A549)
cancer*
ď Efficacy in blood cancer models in mice
ď§ 85-95% growth inhibition in B-Cell cancers

20. Phase 1b/2a Interim Results
from Groups 1 & 2
ď 10 patients enrolled in groups 1 and 2
ď Good tolerability and stable disease at lowest doses
ď 2 patients had stable disease at weeks 3 & 6
ď 1 patient remained stable 4 weeks post dosing
ď No drug-related severe adverse events
ď No dose-limiting toxicities
20
21. Recruitment Continuing at Next
Dose Level
ď§ Phase 1b/2a group 3 is ongoing at 0.2 mg/Kg
⢠0.2 mg/Kg is efficacious dose level in cancer
models in mice
⢠3 patients need to be completed
