Elpis Biopharmaceuticals Showcases Preclinical Data from its Transformative Multi-functional Immuno-Oncology Programs at 2022 AACR Annual Meeting

LEXINGTON, Mass.--()--Elpis Biopharmaceuticals, an IND stage biopharmaceutical company developing next generation immunotherapies to transform cancer treatment, today presented two posters at the American Association for Cancer Research (AACR) Annual Meeting, occurring April 8-13, 2022.

Our pipeline of innovative, multi-functional immunotherapeutics continues to expand and advance, with the goal of addressing the high unmet medical needs of relapse and resistant cancers to current immunotherapies,” says Yan Chen, President and Chief Executive Officer at Elpis Biopharmaceuticals. “We are excited to showcase our latest breakthrough research.”

Discovery of EPIM-001, a tumor targeted engineered IL2 with biased IL2Rβ agonist activities, Poster Number: LB214, Late-Breaking Research: Immunology 2, April 13th 9:00 AM-12:30PM

Key findings from this presentation include:

  • EPIM-001, an anti-PD-L1 tumor targeting IL2 agonist with reduced IL2Rα binding and enhanced IL2Rβ binding, activates CD8+ T Cells and NK cells better than WT IL2, whilst only weakly activating Tregs
  • EPIM-001 monotherapy significantly reduces tumor burden in a “cold” xenograft mouse model that is resistant to anti-PD-1/PD-L1 treatment
  • EPIM-001, Pembrolizumab combination is synergistic in TNBC model
  • IND filing for EPIM-001 planned for Q2 2022

Development of fully human anti-CD19 & CD22 bispecific tandem CAR-T for the treatment of resistant or relapsed B cell malignancies, Poster Number: LB002, Late-Breaking Research: Clinical Research 1, April 10 1:30 PM-5:00 PM

Key findings from this presentation include:

  • EPC-001 showed robust anti-tumor activities in vitro and demonstrated high target specificity with the ability of simultaneous target engagement in solution and on cells
  • Low dose of EPC-001 exhibited potent anti-tumor activity and persistence with favorable memory CAR-T phenotypes
  • EPC-001 is a promising candidate which may prevent target escape to overcome mono-specific CAR associated cancer resistance/relapse
  • EPC-001 is being studied in an investigator-initiated trial to treat CD19 CAR-T resistant/relapsed patients

We are excited to present the preclinical studies of our two lead programs. EPIM-001, an IND-stage molecule, is a bispecific multi-functional tumor targeting IL2Rβ agonist engineered to selectively activate effector T cells and NK cells, potentially enhancing treatment of a broad range of solid tumors” said Kehao Zhao, Chief Scientific Officer of Elpis Biopharmaceuticals. EPC-001 is a fully human CD19/CD22 bispecific tandem CAR-T candidate currently being studied in an investigator-initiated trial. “We are encouraged by the mechanism of EPC-001 to engage and activate CAR-T cells through bispecific or mono-specific targeting, which indicates it may have the ability to prevent and overcome resistance induced by tumor antigen escape.”

Presentations will be available on Elpis’ website at https://elpisbiopharmaceuticals.com.
