3 • Developing a naturally occurring toxin in a peptide delivery system to target solid tumors without the side - effect profile of chemotherapeutic agents • Large market opportunities in multiple cancers including liver, brain and prostate with potential for combination with immunotherapy • Efficacy being demonstrated in mid - stage clinical trials in 2 orphan indications • Positive proof - of - concept Phase 2 liver cancer trial • Highly encouraging data from ongoing Phase 2 brain cancer trial • Mechanism of action protected by robust , global patent estate including exclusive license to technology developed at Johns Hopkins University • Exclusive rights with world - class partners for commercial - scale production and raw material supply • Management has a history of success in oncology drug discovery and development Investment Highlights

 

 

4 • 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

 

 

5 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

7 Compelling Preclinical Data Efficacy Pharmacology • Complete tumor regression with monotherapy in mouse tumor models • No need to combine with other drugs • Fewer side effects • Safety margin of 7 - fold to 10 - fold in mouse • No acquired resistance to mipsagargin Bioanalytical • No released active 12ADT in blood (only intact, inactive mipsagargin) • 12ADT found at very high levels in tumors, less in liver and kidneys, not found elsewhere Toxicology • No effect on liver or cardiovascular system • No effect on bone marrow – no immunosuppression or anemia • Kidney is affected at high doses – dose - dependent, non - cumulative, easily monitored and 100% rapidly reversible
