"Patients with relapsed or refractory PTCL worldwide face limited treatment options and a poor prognosis. We are pleased with the CDE's decision to grant priority review status to golidocitinib, as it recognizes the potential of this groundbreaking drug to improve survival benefits for this underserved patient population. We are fully committed to expediting the NDA filing process and ensuring that golidocitinib becomes available to Chinese patients as quickly as possible." said Xiaolin Zhang, PhD, Chairman and CEO of Dizal.

Golidocitinib, a JAK1-only inhibitor, aimed to address the r/r PTCL dilemma

PTCL is an aggressive non-Hodgkin lymphoma (NHL) that represents approximately 7% to 10% of NHLs worldwide. Patients with r/r PTCL face a poor prognosis, with a 3-year survival rate ranging from 21% to 28%. Currently, there is no established consensus on the standard approach for treating r/r PTCL. Therefore, there is an urgent need for novel and innovative treatment options to improve survival in this patient population.

The Priority Review designation for golidocitinib's application was supported by data from the JACKPOT8 PARTB study, a multinational, pivotal study to evaluate the efficacy and safety of golidocitinib in patients with r/r PTCL. The primary endpoint of the study, objective response rate (ORR) assessed by an independent review committee (IRC), reached 44.3%, with a complete response rate (CRR) of 23.9%. Anti-tumor efficacy was observed across different PTCL subtypes and irrespective of the patients' prior treatment history. The majority of treatment-related adverse events (TRAEs) could be monitored and well managed in the clinic. These findings, highlighting the superior efficacy and safety of golidocitinib, have been widely acknowledged at prestigious conferences such as ASCO, EHA, ICML, and ASH with five oral presentations for four consecutive years. Recently, the Phase I clinical data of golidocitinib for the treatment of r/rPTCL (JACKPOT8 PARTA) was published in the esteemed peer-reviewed journal, Annals of Oncology (Impact Factor: 51.8).

Driving innovation through the fundamentals of translational science

Dizal, a spinoff of AstraZeneca's oncology translational science center, has established a portfolio of five clinical-stage assets with global competitiveness. Among these, golidocitinib represents a major research achievement deeply rooted in the principles of translational science. Dizal was the first to identify and validate the JAK/STAT pathway as a highly promising therapeutic approach for PTCL, leading to the development of golidocitinib as the world's first and currently the only JAK1-only inhibitor in pivotal trial for T cell lymphoma.
