Orum Therapeutics Announces Three Presentations at AACR 2023

BOSTON & DAEJEON, South Korea--(BUSINESS WIRE)--#ADC--Orum Therapeutics, Inc. (“Orum”), a private biotechnology company pioneering the development of tumor-directed targeted protein degraders (TPDs), today announced that it will present new preclinical data for its ORM-5029, ORM-6151, and PD-1-Cbl-b programs in three separate presentations at the American Association for Cancer Research (AACR) Annual Meeting 2023 taking place April 14-19 in Orlando.

ORM-5029 is a potential first-in-class targeted protein degrader therapy currently in a Phase 1 clinical trial for HER2-expressing breast cancer. ORM-6151 is currently in the IND-enabling stage for CD33-positive hematologic malignancies, such as acute myeloid leukemia (AML). Orum’s PD-1-Cbl-b immuno-oncology program utilizes a novel approach designed to deliver proprietary Cbl-b inhibitors specifically to PD-1-expressing exhausted T cells, while blocking PD-1/PD-L1 interaction. This strategy is expected to limit systemic exposure of Cbl-b inhibitors and minimize c-Cbl inhibition that can lead to off-target toxicity.

About Orum’s GSPT1 Platform Using the TPD² Approach

Orum’s GSPT1 platform uses the company’s unique Dual-Precision Targeted Protein Degradation (TPD²) approach to build novel targeted protein degraders combined with the precise tumor cell delivery mechanisms of antibodies to generate innovative, first-in-class, cell-specific TPDs for the treatment of cancer. Orum has developed new molecular glue degrader payloads to specifically degrade an intracellular target protein within cancer cells via the E3 ubiquitin ligase pathway. Conjugated to antibodies, the payloads are designed to be delivered specifically to cancer cells and degrade the intracellular target protein GSPT1 and cause tumor cell death.

About Orum’s TPS² Approach

Orum’s Dual-precision Targeted Protein Stabilization (TPS²) approach combines novel targeted protein inhibitors with the precise cell delivery mechanism of antibodies to increase the levels of intracellular target proteins in a cell-type-specific manner for oncology and immuno-oncology. The first program applying the TPS² approach is a Cbl-b inhibitor (Cbl-bi) conjugated to anti-PD-1 antibody. By delivering Cbl-bi specifically to exhausted T cells, the conjugate restores effector T cell function where PD-1 checkpoint blockade alone is insufficient, while also enabling T cells to overcome the immunosuppressive mechanisms in a tumor microenvironment.

About Orum Therapeutics

Orum Therapeutics is a private, clinical-stage biotech pioneering the development of tumor-directed targeted protein degraders by leveraging its TPD² approach to provide antibody-enabled cell-specific delivery. The company’s proprietary platforms generated using the TPD² approach include the GSPT1 platform, which generates first-in-class antibody drug conjugates. The first therapeutic candidates from the GSPT1 platform are in development for the treatment of solid tumors and hematologic cancers. Orum is located in Boston, US, and Daejeon, South Korea.
