Nurix Therapeutics Receives PRIME Designation from the European Medicines Agency for NX-5948 for the Treatment of Relapsed or Refractory Chronic Lymphocytic Leukemia
The PRIME initiative provides enhanced support to developers of promising medicines to optimize development plans and accelerate evaluation
Pivotal trials of NX-5948 are planned to initiate in 2025
SAN FRANCISCO, Nov. 20, 2024 (GLOBE NEWSWIRE) -- Nurix Therapeutics, Inc. (Nasdaq: NRIX), a clinical stage biopharmaceutical company developing targeted protein modulation drugs designed to treat patients with cancer and inflammatory diseases, today announced that the European Medicines Agency (EMA) has granted PRIME designation for NX-5948, a highly selective degrader of Bruton’s tyrosine kinase (BTK), for the treatment of adult patients with relapsed or refractory chronic lymphocytic leukemia or small lymphocytic lymphoma (CLL/SLL) after at least a BTK inhibitor and a BCL-2 inhibitor. To be eligible for PRIME, medicines must target an unmet medical need and show potential benefit for patients based on early clinical data.
“PRIME designation for NX-5948 is an important recognition of the unmet patient need in CLL, particularly in the growing number of patients whose cancer has progressed following BTK inhibitor and BCL2 inhibitor therapy,” said Arthur T. Sands, M.D., Ph.D., president and chief executive officer of Nurix. “This designation follows encouraging safety and efficacy data from our ongoing Phase 1 clinical trial, demonstrating early promise of clinical benefit as well as mechanistic data supporting the activity of NX-5948 independent of mutations that confer resistance to covalent and non-covalent BTK inhibitors.”
The PRIME initiative, launched by the EMA in 2016, offers early, proactive and enhanced support to developers of promising medicines to optimize development plans and accelerate evaluation so these medicines can reach patients faster.
About NX-5948
NX-5948 is an investigational, orally bioavailable, brain penetrant, small molecule degrader of BTK. NX-5948 is designed to specifically eliminate BTK, a key growth signaling protein in B cells, through degradation by the ubiquitin proteasome system of the cell. NX-5948 is currently being evaluated in a Phase 1 clinical trial in patients with relapsed or refractory B cell malignancies. Nurix has previously reported that NX-5948 is highly potent against a range of tumor cell lines that are resistant to current BTK inhibitor therapies, an important consideration in heavily pretreated CLL/SLL patient populations. Additional information on the ongoing clinical trial can be accessed at clinicaltrials.gov (NCT05131022).
About Nurix
Nurix Therapeutics is a clinical stage biopharmaceutical company focused on the discovery, development and commercialization of innovative small molecules and antibody therapies based on the modulation of cellular protein levels as a novel treatment approach for cancer, inflammatory conditions, 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 cells and NK cells. Nurix is headquartered in San Francisco, California. For additional information visit http://www.nurixtx.com.

All statements that reflect Nurix’s expectations, assumptions or projections about the future, other than statements of historical fact, are forward-looking statements, including, without limitation, statements regarding the potential advantages and therapeutic benefits of NX-5948, including its potential role in the treatment of patients whose cancer has progressed following BTK inhibitor and BCL2 inhibitor therapy or its role in addressing mutations that confer resistance to covalent and non-covalent BTK inhibitors; and the potential benefits of PRIME designation. Forward-looking statements reflect Nurix’s current beliefs, expectations, and assumptions. Although Nurix believes the expectations and assumptions reflected in such forward-looking statements are reasonable, Nurix can give no assurance that they will prove to be correct. Forward-looking statements are not guarantees of future performance and are subject to risks, uncertainties and changes in circumstances that are difficult to predict, which could cause Nurix’s actual activities and results to differ materially from those expressed in any forward-looking statement. Such risks and uncertainties include, but are not limited to: (i) the risks inherent in the drug development process, including the unexpected emergence of adverse events or other undesirable side effects during clinical development; (ii) uncertainties related to the timing and results of clinical trials; (iii) the risk that clinical trial data are subject to differing interpretations and assessments by regulatory authorities; (iv) whether Nurix will be able to successfully complete clinical development for, obtain regulatory approval of and ultimately commercialize NX-5948; (v) whether Nurix will be able to fund its research and development activities and achieve its research and development goals; (vi) the impact of economic and market conditions and global and regional events on Nurix’s business and clinical trials; (vii) whether Nurix will be able to protect intellectual property and (viii) other risks and uncertainties described under the heading “Risk Factors” in Nurix’s Quarterly Report on Form 10-Q for the fiscal period ended August 31, 2024, and other SEC filings.
