7 Scientific Background & IP

8 • GenSpera’s platform is based on exclusively licensed technology developed at Johns Hopkins University and the University of Copenhagen • Platform combines a cytotoxin with a protective peptide, creating a blood soluble prodrug that remains inactive until in the presence of a specific enzyme ▪ Selected enzyme is chosen due to its high level of expression in tumors ▪ The peptide helps solubilize the prodrug and prevents its internalization into cells until the peptide is removed ▪ The enzyme cleaves the peptide from the prodrug and releases the active ingredient only within the tumor, resulting in tumor death • Unique mechanism of action with enhanced anti - tumor activity • Targeted and localized cytotoxic presence minimizes side effects • Target cells unable to acquire resistance Platform Overview

9 Prostate - Specific Membrane Antigen (PSMA): Pan - Tumor Target • Type II transmembrane glycoprotein • Unique proteolytic activity • Highly expressed in normal and malignant prostate epithelial cells • Selective expression in the vascular endothelium of solid tumors – both established and new growth PSMA PSMA is expressed by tumor vasculature

10 Mechanism of Action 1. Blood vessels feed living tumor 2. Drug circulates in bloodstream in benign fashion 3. PSMA enzyme within tumor blood vessels activates drug 4. Activated drug kills blood vessels and tumor cells 5. Death of t umor Precision Targeting by Design → Potential for Complete Tumor Kill → Fewer Side Effects

11 • Exclusive license to use technology developed at Johns Hopkins University and the University of Copenhagen • Current i nfusion composition • Patent coverage in U.S. to 2023 – additional years via patent restoration and ODD • Data exclusivity outside of U.S. − up to 10 years after drug approval in EU • New composition - of - matter Patent Application • Worldwide exclusivity expected through 2033 • Other applications filed for methods of use, formulations, process improvements • Exclusive partnership with Phyton Biotech for commercial - scale thapsigargin production • The name mipsagargin has novel stem – new drug class differentiation value Intellectual Property

12 Mipsagargin: First - in - class Oncologic A gent

13 • A prodrug that becomes active only at tumor site • Plant - based toxin (thapsigargin derivative, 12ADT) is combined with a protective peptide • Peptide targets the PSMA enzyme, which is highly expressed on the surface of tumor vasculature • PSMA removes the peptide, releasing toxin that kills blood vessels feeding tumor and also cancer cells • Targeted drug delivery significantly reduces side effects • No apparent effect on bone marrow – combination with immunotherapy is viable • Manageable side effect profile • Orphan drug designation for liver cancer; pending for brain cancer • Prolonged disease stabilization (via RECIST) in a significant percentage of liver cancer patients Mipsagargin – Lead Drug Candidate 12ADT Extraction and chemical modification Masking and targeting peptide attached PSMA removes peptide, releasing toxin at tumor site

14 • Mipsagargin consists of a thapsigargin derivative, 12ADT, coupled to a peptide that helps solubilize the prodrug and prevents its internalization into cells until the peptide is removed • PSMA (an enzyme highly expressed on the surface of cancer tumor vasculature) recognizes and removes the peptide , releasing 12ADT only within the tumor, bringing about cell death Mipsagargin – Chemistry O O H OH CH 3 OH O CH 3 O O O O O CH 3 O H 3 C O H 3 8 1 H N N H H N N H H N N H H N N H O O NH 2 O O O H 2 N O HO O OH O HN N N O O H N O (CH 2 ) 11 His (H) Ser- (S) Ser- (S) Lys- (K) Leu- (L) Gln- (Q) Leu- (L)12ADT - PSA Hydrolysis O O H OH CH 3 OH O CH 3 O O O O O CH 3 O H 3 C O H 3 8 1 H N N H H N N H H N N H H N N H O O NH 2 O O O H 2 N O HO O OH O HN N N O O H N O (CH 2 ) 11 His (H) Ser- (S) Ser- (S) Lys- (K) Leu- (L) Gln- (Q) Leu- (L)12ADT - O O H OH CH 3 OH O CH 3 O O O O O CH 3 O H 3 C O H 3 8 1 O O H OH CH 3 CH 3 OH O CH 3 O O O O O CH 3 O H 3 C O H 3 8 1 H N N H H N N H H N N H H N N H O O NH 2 O O O H 2 N O HO O OH O HN N N O O H N O H N N H H N N H H N N H H N N H O O NH 2 O O O H 2 N O HO O OH O HN N N O O H N O (CH 2 ) 11 His (H) Ser- (S) Ser- (S) Lys- (K) Leu- (L) Gln- (Q) Leu- (L)12ADT - PSA Hydrolysis O O H OH CH 3 OH O CH 3 O O O O O CH 3 O H 3 C O H 3 8 1 (CH 2 ) 11 12ADT- NH O O O ONH 2 OH H N N H O HO O H N OH O HO O O HO O NH O O O ONH 2 OH H N N H O HO O H N OH O HO O O HO O -N H Asp Glu Glu Glu Glu PSMA Hydrolysis O O H OH CH 3 OH O CH 3 O O O O O CH 3 O H 3 C O H 3 8 1 O O H OH CH 3 CH 3 OH O CH 3 O O O O O CH 3 O H 3 C O H 3 8 1 (CH 2 ) 11 12ADT- NH O O O ONH 2 OH H N N H O HO O H N OH O HO O O HO O NH O O O ONH 2 OH H N N H O HO O H N OH O HO O O HO O -N H Asp Glu Glu Glu Glu PSMA Hydrolysis Thapsigargin Analog (12ADT)

33 Impressive clinical activity • Highly differentiated from other anti - cancer approaches • Outstanding clinical safety profile • Minimal and manageable side effects ▪ Fatigue, nausea, rash, reversible creatinine increase ▪ No apparent effect on bone marrow • Data strongly suggestive of clinical activity in second - line HCC ▪ Study participants experienced a median time to progression of 4.5 months (p<0.001), more than twice the time demonstrated in prior studies with placebo or ineffective agents ▪ 6 3 % of patients experienced disease stabilization (via RECIST) at 2 months ▪ Prolonged disease stabilization in a significant percentage of patients – 24% with stable disease > 5 months • Additionally, mipsagargin demonstrated decreased blood flow in liver tumors as measured by DCE - MRI Phase 2 HCC Trial Results Overview

34 Next HCC Clinical Development Steps

35 • Liver cancer is the most common type of cancer in Southeast Asia • Three fourths of worldwide liver cancer cases in males, and two thirds in females, occur in 15 Asian countries ▪ Compared to the US and EU, high rates of Hepatitis B virus (HBV) prevalence, and to a lesser extent HCV, are leading factors for higher liver cancer rates • Regular screening of high - risk HBV carriers in Eastern Asia allows for early detection of liver cancer when potentially curative treatment can still be offered ▪ Clinical development program for mipsagargin will initially be focused in East Asia ▪ Rapid trial initiation in Singapore, Taiwan and/or Hong Kong because of potential to access US INDs Next Steps: Asia Represents Advantageous Environment for Clinical Development Source: Pfizer Facts: The Burden of Cancer in Asia, 2008.
