“This research provides important validation for our clinical-stage programs across multiple cancer types,” said Russell Hayward, CEO, Etira. “We are extremely encouraged by its impact on our ongoing clinical trials with ERX-315.”
"Our preclinical work has validated the targeting of LIPA with ERX-208 and ERX-315 in multiple ovarian and hepatocellular cancer subtypes respectively,” Dr. Ratna Vadlamudi, UT Health San Antonio. “We are establishing a clear paradigm for the expanded use of these novel agents either alone or in combination with existing drugs.”

WHAT: Three presentations at the American Association for Cancer Research (AACR) Annual Meeting 2025 showcase the ongoing development of Etira's platform that targets lysosomal acid lipase A (LIPA) to induce endoplasmic reticulum (ER) stress and cell death in cancer.
WHERE
● AACR Annual Meeting 2025, April 25-30, 2025
● McCormick Place Convention Center
● Chicago, Illinois
PRESENTATIONS
Oral Presentation
● Title: “Optimization of the LIPA Targeting Agent for the Treatment of Ovarian Cancer”
● Session: MS.CH01.01 — Innovative Approaches in Drug Discovery: Novel Leads, Degraders and AI-driven Solutions
● Presenter: Dr. Ratna Vadlamudi, UT Health San Antonio
● Date/Time: April 28, 2025 | 2:35 p.m. – 2:50 p.m.
● Conclusions: ERX-208 targets LIPA and potently causes catastrophic endoplasmic reticulum stress in multiple ovarian cancer subtypes.
● Implications: ERX-208 is a viable candidate for clinical translation in ovarian cancer,
Poster Presentation
● Title: “Targeting ER Stress for Treating Hepatocellular Carcinoma (HCC)”
● Session: PO.ET06.01 — Cell Death Pathways and Treatment
● Presenter: Adriana Baker, UT Health San Antonio
● Date/Time: April 28, 2025 | 9:00 a.m. – 12:00 p.m
● Conclusions: ERX-315 targets LIPA and potently causes catastrophic endoplasmic reticulum stress in multiple subtypes of hepatocellular cancer.
● Implications: Ongoing ERX-315 clinical trials should include patients with advanced liver cancer.
Poster Presentation — Undergraduate Symposium
● Title: “Combining LIPA Inhibitor ERX-208 with DNA-Damaging Agents as a Novel Strategy to Enhance Ovarian Cancer Treatment”
● Presenter: Durga Meenakshi Panneerdoss, UT Health San Antonio
● Date: April 26, 2025
● Conclusions: In an unbiased evaluation of combination of ERX-208 with 147 FDA-approved chemotherapeutic agents, ERX-208 was noted to be synergistic with DNA-damaging agents like cisplatin.
● Implications: Combination of ERX-208 with DNA-damaging agents such as cisplatin are more effective in ovarian cancers than ERX-208 or cisplatin alone.
SIGNIFICANCE: These studies build on the foundational science first described in Etira’s 2022 Nature Cancer paper and reinforce LIPA targeting as a versatile approach that addresses therapy resistance across multiple solid tumor types. ERX-315, an optimized analog of ERX-41, is currently being evaluated in a Phase 1 clinical trial (NCT06533332) for patients with therapy-resistant metastatic cancers.
