Nurix Therapeutics Announces Partial Clinical Hold For NX-2127 Phase 1 Trial
Currently enrolled patients may continue receiving NX-2127
SAN FRANCISCO, CA, November 1, 2023 – Nurix Therapeutics, Inc. (Nasdaq: NRIX), a clinical stage biopharmaceutical company developing targeted protein modulation drugs designed to treat patients with hematologic malignancies and solid tumors, today announced that the U.S. Food and Drug Administration (FDA) has placed a partial clinical hold on U.S. Phase 1 NX-2127-001 study evaluating NX-2127 in various B-cell malignancies. Screening and enrollment of new study participants has been paused. Patients currently enrolled in the clinical study who are deriving clinical benefit may continue to receive treatment in accordance with the ongoing study protocol. Nurix is working with the FDA to resolve the partial clinical hold as soon as possible.
The partial clinical hold follows the company’s communication to the FDA of its intention to transition to an improved manufacturing process. Nurix’s other drug programs are not affected by the NX-2127 manufacturing process improvement.
“The initial NX-2127 manufacturing process produced a Phase 1 drug product that has yielded important proof-of-concept results with meaningful clinical responses in patients with advanced B-cell malignancies,” said Arthur T. Sands, M.D., Ph.D., president and chief executive officer of Nurix. "While the partial hold is in effect, we will supply the current drug product for patients who continue on therapy in the Phase 1 study and will work expeditiously with FDA to introduce the improved NX-2127 manufacturing process and drug product into our clinical development plan.”
About NX-2127
NX-2127 is a novel bifunctional molecule that degrades BTK and cereblon neosubstrates Ikaros (IKZF1) and Aiolos (IKZF3). NX-2127 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 www.clinicaltrials.gov (NCT04830137).
About Nurix Therapeutics, Inc.
Nurix Therapeutics is a clinical stage biopharmaceutical company focused on the discovery, development and commercialization of innovative medicines based on the modulation of cellular protein levels as a novel treatment approach for cancer and other challenging diseases. Leveraging extensive expertise in E3 ligases together with proprietary DNA-encoded libraries, Nurix has built DELigase, an integrated discovery platform, to identify and advance novel drug candidates targeting E3 ligases, a broad class of enzymes that can modulate proteins within the cell. Nurix’s drug discovery approach is to either harness or inhibit the natural function of E3 ligases within the ubiquitin-proteasome system to selectively decrease or increase cellular protein levels. Nurix’s wholly owned, clinical stage pipeline includes targeted protein degraders of Bruton’s tyrosine kinase, a B-cell signaling protein, and inhibitors of Casitas B-lineage lymphoma proto-oncogene B, an E3 ligase that regulates activation of multiple immune cell types including T cell and NK cells. Nurix is headquartered in San Francisco, California. For additional information visit http://www.nurixtx.com.
