Prelude Therapeutics Announces Clinical Trial Collaboration with BeiGene to Evaluate PRT2527 in Combination with Zanubrutinib in Hematologic Cancers
WILMINGTON, Del., March 15, 2023 (GLOBE NEWSWIRE) -- Prelude Therapeutics Incorporated (Prelude) (Nasdaq: PRLD), a clinical-stage precision oncology company, today announced a clinical trial collaboration with BeiGene, for future evaluation of its investigational CDK9 inhibitor, PRT2527, in combination with BeiGene’s BTK inhibitor, zanubrutinib, in hematologic malignancies.
Inhibition of BTK is an active therapeutic approach in several B cell malignancies and the combination of CDK9 inhibition with BTK inhibition has demonstrated, in recent data publications, synergistic clinical efficacy over BTK inhibition alone; hence, there is a strong rationale for studying the combination in patients with certain hematologic malignancies.
“The opportunity to combine Prelude’s potent, selective and potentially best-in-class CDK9 inhibitor with BeiGene’s next-generation highly efficacious and tolerable BTK inhibitor, zanubrutinib, reflects our commitment to bringing the most promising options to patients,” said Jane Huang, MD, President and Chief Medical Officer, Prelude Therapeutics.
Under terms of the clinical trial collaboration agreement, BeiGene will provide zanubrutinib to Prelude, and Prelude will retain all global operational, development and commercialization rights and responsibilities for PRT2527.
PRT2527 was designed to be a potent and selective Cyclin-dependent kinase 9, or CDK9, inhibitor. In preclinical studies, PRT2527 was shown to reduce MCL1 and MYC protein levels and was highly active in preclinical models at well-tolerated doses. PRT2527 has demonstrated high potency and kinase selectivity which may offer improved efficacy and safety compared to less selective CDK9 inhibitors, allowing for rapid development in combinations. PRT2527 is currently being studied as monotherapy in a Phase 1 dose-escalation study in advanced solid tumors, as well as in relapsed/refractory hematologic malignancies.

Zanubrutinib is a small-molecule inhibitor of Bruton’s tyrosine kinase (BTK) discovered by BeiGene scientists that is currently being evaluated globally in a broad clinical program as a monotherapy and in combination with other therapies to treat various B-cell malignancies. Zanubrutinib was specifically designed to deliver targeted and sustained inhibition of the BTK protein by optimizing bioavailability, half-life, and selectivity. With differentiated pharmacokinetics compared to other approved BTK inhibitors, zanubrutinib has been demonstrated to inhibit the proliferation of malignant B cells within a number of disease-relevant tissues.
Zanubrutinib is supported by a broad clinical program which includes more than 4,700 subjects in 35 trials in more than 30 geographies. To date, zanubrutinib (BRUKINSA®) is approved in over 60 markets, including the United States, China, the European Union, Great Britain, Canada, Australia, South Korea, Iceland, Norway and Switzerland.
