About OP-3136
OP-3136 is a novel, orally available small molecule that potently and selectively inhibits lysine acetyltransferase 6 (KAT6), an epigenetic target that is dysregulated in breast and other cancers. In preclinical studies, OP-3136 has demonstrated significant anti-proliferative activity in ER+ breast cancer models and is combinable and synergistic with endocrine therapies, including palazestrant and cyclin-dependent kinase 4/6 (CDK4/6) inhibitors. The Investigational New Drug (IND) application for OP-3136 was cleared by the U.S. Food and Drug Administration (FDA) in December 2024 and patients are currently enrolling in the Phase 1 clinical trial.

About DEL-AI
DEL-AI is Nurix’s discovery platform which employs advanced machine learning to enable all aspects of Nurix’s discovery engine, starting with DNA encoded library (DEL) hit-finding and degrader design, followed by automated chemistry synthesis and direct-to-biology screening and optimization, to rapidly generate degraders and degrader antibody conjugates (DACs) as new chemical entity drug candidates. By leveraging hundreds of billions of DEL compound binding signatures derived from thousands of DEL affinity screens collected from a diverse set of highly validated protein targets, our DEL-AI platform can prospectively identify binders as starting points for drug discovery for virtually any pharmaceutically relevant target.

About Bexobrutideg (NX-5948)
Bexobrutideg is an investigational, orally bioavailable, brain penetrant, small molecule degrader of BTK. Bexobrutideg is currently being evaluated in a Phase 1 clinical trial in patients with relapsed or refractory B cell malignancies. Additional information on the ongoing clinical trial can be accessed at clinicaltrials.gov (NCT05131022).

About NRX-0305
NRX-0305 is a potent, selective, and orally bioavailable mutant-specific BRAF degrader that Nurix is exploring for use in oncology. Nurix has reported preclinical data demonstrating potent anti-tumor activity in multiple cell line-derived and patient-derived xenograft disease models representing Class I, Class II and Class III B-RAF mutations. Anti-tumor activity was also observed in the setting of CNS disease and treatment-resistance, suggesting the potential for utility across a broad range of solid tumor types

About Aurora A Kinase
Aurora A kinase (AURKA) is an oncogene frequently overexpressed in adult solid tumors, hematologic malignancies, and pediatric cancers. Several AURKA inhibitors are effective in preclinical tumor models, but this activity has failed to translate into clinical efficacy. To address the limitations of inhibitors, Nurix has designed bifunctional targeted protein degraders of AURKA that enable removal of both enzymatic and scaffolding functions.

On March 25, 2025 Elevation Oncology, Inc.

EO-1022 is an antibody drug conjugate (ADC) containing seribantumab, a fully human IgG2 anti-HER3 monoclonal antibody (mAb), which is site-specifically conjugated at glycan to the monomethyl auristatin E (MMAE) payload with a drug-to-antibody ratio (DAR) of 4. Elevation Oncology designed EO-1022, leveraging the advanced site-specific conjugation technology platform licensed from Synaffix B.V. Elevation Oncology is developing EO-1022 for the treatment of solid tumors that express HER3, including breast cancer and non-small cell lung cancer, and expects to file an IND application in 2026.

"We are eager to share the first preclinical data for EO-1022 at the AACR (Free AACR Whitepaper) Annual Meeting," said Joseph Ferra, President and Chief Executive Officer of Elevation Oncology. "With EO-1022, we are combining the most advanced site-specific conjugation technology platform with the clinically validated MMAE payload, which is widely used across ADC programs but has yet to be introduced into a HER3-targeting ADC in the clinic. We believe this unique combination will enable us to provide a new treatment option to patients with HER3-expressing solid tumors, including those who are refractory to other HER3-targeting agents in development. We look forward to advancing EO-1022 into clinical development next year."

About EO-1022

Elevation Oncology is developing EO-1022, a potentially differentiated HER3 ADC for the treatment of HER3-expressing solid tumors, including breast cancer and non-small cell lung cancer. EO-1022 consists of seribantumab, a fully human IgG2 anti-HER3 antibody, site-specifically conjugated at glycan to the MMAE payload with a DAR of 4. It leverages seribantumab’s desirable internalization properties and advanced site-specific ADC technology which makes possible the use of the potent cytotoxic MMAE payload. Elevation Oncology expects to file an IND application in 2026.

About Ateganosine

Ateganosine (THIO, 6-thio-dG or 6-thio-2’-deoxyguanosine) is a first-in-class investigational telomere-targeting agent currently in clinical development to evaluate its activity in Non-Small Cell Lung Cancer (NSCLC). Telomeres, along with the enzyme telomerase, play a fundamental role in the survival of cancer cells and their resistance to current therapies. The modified nucleotide 6-thio-2’-deoxyguanosine induces telomerase-dependent telomeric DNA modification, DNA damage responses, and selective cancer cell death. Ateganosine-damaged telomeric fragments accumulate in cytosolic micronuclei and activates both innate (cGAS/STING) and adaptive (T-cell) immune responses. The sequential treatment with ateganosine followed by PD-(L)1 inhibitors resulted in profound and persistent tumor regression in advanced, in vivo cancer models by induction of cancer type–specific immune memory. Ateganosine is presently developed as a second or later line of treatment for NSCLC for patients that have progressed beyond the standard-of-care regimen of existing checkpoint inhibitors.

Title: ORIC-944, a PRC2 inhibitor with best-in-class properties, restores luminal features and restricts adaptation in prostate cancer models, conferring synergy with AR pathway inhibitors
Abstract Number: 452
Date & Time: Sunday, April 27, 2025, 2:00 – 5:00 p.m. CT
Session Category: Experimental and Molecular Therapeutics
Session Title: Epigenetic Targets
Location: Poster Section 20

Abstract Highlights
ORIC-944 is a potent, highly selective, orally bioavailable, allosteric inhibitor of PRC2 that demonstrates best-in-class drug properties, including potency, solubility, and pharmacokinetics, with half-life supporting once daily dosing. In preclinical prostate cancer models, ORIC-944 demonstrated robust inhibition of PRC2, enhanced luminal cell state, and increased androgen receptor (AR) signaling. Analysis of chromatin revealed that ORIC-944 specifically restricts accessibility to lineage-associated transcription factors known to impart cellular plasticity in prostate cancer. This plasticity-restricted luminal state conferred by PRC2 inhibition is dependent on AR, leading to antitumor activity either in the hormone-depleted context or in the combination setting with an AR pathway inhibitor (ARPI). Together these data indicate that ORIC-944 reinforces a luminal cell state and, notably, restricts access to plasticity genes leading to a highly AR-dependent state in prostate models. This mechanism supports the observed preclinical synergy between PRC2 inhibition and ARPIs in both ARPI-sensitive and ARPI-resistant settings. These results position ORIC-944 as a potential best-in-class PRC2 inhibitor that blocks prostate tumor adaptation, restores luminal features, and sensitizes tumors to ARPIs. A phase 1b trial of ORIC-944 in combination with ARPIs is ongoing in metastatic prostate cancer (NCT05413421).
