Slide 5: Investment Highlights
Investment Highlights LadRx has developed elegant tumor targeting and release molecules called LADR that are based on small molecular entities (no complex antibodies or nanoparticles) allowing for higher dosing and lower off-target tox ➢ First LADR drug Aldoxorubicin was licensed to Immunity Bio and
Slide 6: LADR=Linker-Activated Drug Release
LADR=Linker-Activated Drug Release LADR-based drugs take advantage of circulating albumin as trojan horse: ➢ Major source of amino acids for tumors* ➢ Tumors use as carrier for metabolites, hormones, nutrients* ➢ Undergoes macropinocytosis* ➢ Accumulates in tumors due to EPR* ➢ Long half life* LADR:
Slide 7: Aldoxorubicin: 1st Gen LADR-Based Drug Has Proven Higher Dosing with Improved Safety
Aldoxorubicin: 1st Gen LADR-Based Drug Has Proven Higher Dosing with Improved Safety in Human Trials Compared to Native Doxorubicin ➢ LADR allows for 3X higher dosing or more of doxorubicin When attached to LADR backbone, ➢ Aldoxorubicin crosses the Blood-Brain doxorubicin has Barrier been dosed in
Slide 8: Next-Gen LADRs: LADR 7, 8, 9, 10
Next-Gen LADRs : LADR 7, 8, 9, 10 • High-throughput screening yielded four compounds selected for evaluation: • LADR 7: Auristatin-E with Ketone Linker • LADR 8: Auristatin-E with Ester Linker • LADR 9: Maytansine with Ketone Linker • LADR 10: Maytansine with Ester Linker • Auristatins and Maytansin

Slide 13: All Four LADR Candidates Meet Initial Development Criteria
All Four LADR Candidates Meet Initial Development Criteria Maytansinoid LADR™s (LADR- Auristatin LADR™s 9 and (LADR-7 and LADR-8) LADR-10) Selective Binding to Albumin and Stable in Plasma Payload Releases at pH 4 Robust Anti-Tumor Activity in Multiple Tumor Types Durable Responses Averaged 60‒90 Da
Slide 14: Next-gen LADR Progress Towards IND
Next-gen LADR Progress Towards IND ✓ Stability in plasma (mouse, rat, dog, monkey, human) ✓ pH-dependent release ✓ Rat and mouse MTD ✓ In-vitro efficacy ✓ In-vivo efficacy (small and large tumor PDX and CDX) ✓ Non-GLP rodent tox ✓ CMC GLP Mfg Run GLP rodent tox Time to IND 12-18 months from project
Slide 15: Status of Arimoclomol and Aldoxorubicin
Status of Arimoclomol and Aldoxorubicin In June 2023, LadRx entered an agreement with Xoma, Inc. in which economic rights to arimoclomol and aldoxorubicin were transferred to Xoma, Inc. In exchange for the economic rights to arimoclomol and aldoxorubicin, LadRx received or will receive: $5M gross pr
Slide 16: Summary
Summary LadRx has developed an efficient delivery platform for chemotherapeutic agents that takes advantage of the concentration of albumin in solid tumors. Being small molecules, the agents are easier/cheaper to manufacture than macromolecules, confer solubility, and cross the blood-brain barrier.
