SAN FRANCISCO - Nurix Therapeutics, Inc. (NASDAQ:NRIX), a biopharmaceutical company, announced the development of a novel inhibitor targeting a key protein involved in immune cell regulation, marking a significant step in cancer treatment. The company presented the structure and discovery of NX-1607 at the American Chemical Society Spring 2024 meeting, highlighting its potential as the first inhibitor of the E3 ligase CBL-B to enter clinical studies.
NX-1607, described as an intramolecular glue, inactivates CBL-B by locking it in a closed state. This mechanism is pivotal as CBL-B does not possess a traditional binding pocket, which typically hinders the development of inhibitors. The drug aims to lower the threshold for T-cell activation, potentially enhancing the body's immune response to cancer.
Nurix's Chief Scientific Officer, Gwenn Hansen, Ph.D., emphasized the company's unique approach combining structure-based drug design with expertise in E3 ligases, leading to the creation of this first-in-class drug candidate.
The ongoing Phase 1 trial assesses NX-1607's safety, tolerability, and preliminary anti-tumor activity in patients with advanced malignancies, including solid tumors and lymphoma. The study includes monotherapy and combination cohorts with paclitaxel, a chemotherapy drug. In 2024, Nurix anticipates presenting data from the trial's dose-escalation phase and determining doses for the expansion of Phase 1b cohorts.
CBL-B, an E3 ubiquitin ligase in immune cells, modulates T-cell activation. Its inhibition could potentially reverse tumor resistance mechanisms by enabling T-cell activation with low antigen expression on tumor cells.
Nurix's focus on cellular protein modulation through E3 ligases aims to advance treatments for cancer and inflammatory diseases. The company's proprietary DELigase platform has facilitated the discovery of other drug candidates targeting E3 ligases.
