3 GenSpera - Who We Are Leader in the development of targeted prodrug cancer therapeutics • First in class New Chemical Entity (NCE) – unique biochemical mechanism of action • Potential for “complete kill” – active in both slow and rapidly dividing cells • Prodrug targeted delivery system reduces side effects, maximizes efficacy • Technology originated at Johns Hopkins. GenSpera holds 100% of rights, no milestones or royalties due to third parties • 9 patents issued, 4 patents pending • Phase I clinical trial underway at Johns Hopkins, Univ Wisconsin, CTRC

4 GenSpera’s Breakthrough Technology Traditional chemotherapy features: • Targets cell division • Typified by side effects, drug resistance • Little effect on slow growing tumors or cancer stem cells • Just doesn’t work well enough Our “molecular grenade” features are a major breakthrough: • Kills independent of cell division rate (kills slow - growing tumors and stem cells) • Targeted delivery specifically to tumors (minimize side effects, maximize efficacy) • No development of drug resistance • Complete tumor regression observed in multiple preclinical animal studies • As a “monotherapy,” early clinical trials will be simpler, faster, and less expensive than other chemotherapy trials

5 How Our Molecular Grenades Work Our active drug, with a targeting/masking agent attached, i.e., the prodrug, is inactive in the blood stream – similar to a grenade with an intact pin… The active drug, no longer soluble, “precipitates” directly into nearby cells and kills them. …until it finds an “enzyme” (tumor marker ), which is found only at our “target site,” that “pulls the pin on the grenade” off the targeting/masking agent. NORMAL CELL CANCER CELL (or blood vessel of tumors)

6 Thapsigargin – A Novel Cytotoxin • Isolated from seeds of Thapsia garganica • 100 kg seeds yields ~1 kg of thapsigargin • Potent inhibitor of ER Ca2+ ATPase pump • Kills cancer cells independent of growth rate • Isolated from seeds of Thapsia garganica • 100 kg seeds yields ~1 kg of thapsigargin • Potent inhibitor of ER Ca2+ ATPase pump • Kills cancer cells independent of growth rate

7 How We Make Our Molecular Grenades 12 - ADT • Derived from Mediterranean plant (exclusive supply agreements) • Well - characterized and studied • Kills: – Slow - and fast - growing cancer cells – Cancer stem cells – Established vascular cells • Patent - protected* • Peptide removed by enzyme at the target site • Different cancers = different peptides • Peptides – Patent - protected* – Based on extensive research by Scientific Advisory Board members • Peptide attached to 12ADT • Renders 12ADT : – Inactive – Soluble – Targets tumor • Intravenous application * 9 patents & 4 patent applications; no milestone or royalty payments are owed Peptide Attached Prodrug Delivered to Tumor Tumor

8 Compelling G - 202 Biological Data Efficacy Pharmacology • Complete tumor regression with monotherapy – No need to combine with other drugs – Fewer side effects • Safety margin of 7 to 10 - fold in mouse • No acquired resistance to G - 202 Bioanalytical • In blood can only find intact G - 202 and no released active 12ADT • 12ADT is found at very high levels in tumors, less found in liver and kidneys, not found elsewhere - Targeted Delivery! Toxicology • No effect on liver or cardiovascular system • No effect on bone marrow – no immunosuppression or anemia • Kidney is the affected organ at high doses – dose - dependent, non - cumulative, easily monitored (blood test), and 100% rapidly reversible. May be attenuated via hydration of the patient.

9 Clinical Trial Protocol and Highlights Phase I: Safety, Tolerability, Pharmacokinetics • Open label, all solid tumors with failed treatment - about 30 patients • Dose escalation to Maximum Tolerated Dose • 25 patients dosed, IRB approvals for trial expansion and acceleration • 3 US sites active • Dose - proportional pharmacokinetic data through all seven cohorts Phase Ib Cohort Expansion: Post Chemotherapy Prostate Cancer Patients Planned Phase II Trial: Castrate Resistant, Chemo - naive Prostate Cancer Patients • 3 sites in the US, 2 sites in the UK – O btain possible early signal of activity via PSA response – O btain EMEA trial approval Budget includes 4 concurrent Phase II trials in different tumor types.

10 Achievements and Milestones Recent achievements: • G - 202 exposure in patients is at levels expected to show efficacy • Process improvements in G - 202 manufacture • Second cGMP clinical batch of G - 202 is in use Near - term milestones: • Continued enrollment and dose - escalation in G - 202 Phase I study • Initiate Phase Ib post - chemotherapy prostate cancer study • Initiate Phase II castrate - resistant chemotherapy - naïve prostate cancer study in US and UK
