One study evaluated DZD6008, an investigational fourth-generation EGFR TKI, in pre- treated NSCLC patients with EGFR C797X mutations following progression on third- generation EGFR TKI treatment. The results were featured in an oral presentation. The other study reported results for golidocitinib, a JAK1-selective inhibitor, combined with an anti-PD-1 antibody as a first-line treatment for PD-L1-positive, advanced NSCLC without driver mutations. **DZD6008:** **A Fourth-Generation EGFR TKI Overcomes Resistance Following Third- Generation EGFR TKI Failure** The latest findings showed that DZD6008 demonstrated strong and durable anti-tumor activity in patients relapsed from third-generation EGFR TKI with a favorable safety profile. ◦ The majority of patients (82.1%) had tumor shrinkage following DZD6008 treatment. Higher response rate is expected with longer treatment. ◦ Tumor response is durable, with 6 months progression free survival (PFS) rates at 70.6% and 61.8%, respectively for 40 mg and 60 mg cohorts. The median duration of response (DoR) was not reached. ◦ Excellent blood-brain barrier (BBB) penetration was observed, including strong intracranial anti-tumor activity among patients with baseline brain metastasis. ◦ DZD6008 demonstrated a favorable safety profile with high selectivity for wild- type EGFR, resulting in minimal adverse effects. Patients with EGFR-mutant NSCLC whose disease progresses on or after third-generation EGFR TKI treatment often acquire resistance mutations, among which EGFR C797X is one of the most frequently reported. DZD6008 is a fourth-generation EGFR TKI designed with full BBB penetration and high selectivity over wild-type EGFR. Preclinical and clinical data support its potent activities against single, double and triple EGFR mutations (L858R/19del, T790M, C797X). **Golidocitinib: A JAK1 Inhibitor Combined with Anti-PD-1 Demonstrates Durable Clinical Benefit** Among 47 enrolled treatment-naïve patients with advanced NSCLC, golidocitinib plus sintilimab following chemo-immunotherapy demonstrated encouraging and durable anti- tumor efficacy, particularly in those with high PD-L1 expression. Profound improvement of irAE was noticed. Dr. Xiaolin Zhang, CEO of Dizal, said: "Main reasons for patients relapsed from 3^(rd) generation EGFR TKI treatment include acquired resistance mutations and CNS metastasis. DZD6008 was designed to address these clinical issues. The data presented confirmed that DZD6008 met our design criteria and has the potential to provide an oral safe treatment option for these patients. We are very excited by the clinical data. We look forward to collaborating with investigators worldwide to accelerate its clinical development globally." **About Golidocitinib (DZD4205)** Golidocitinib is currently the first and only Janus kinase 1 (JAK1) inhibitor being evaluated for the treatment of r/r PTCL. In June 2024, golidocitinib was approved by the National Medical Products Administration (NMPA) of China for the treatment of adult patients with relapsed or refractory peripheral T-cell lymphoma (r/r PTCL). At the data cut-off date of August 31, 2023, golidocitinib has demonstrated robust and durable anti-tumor efficacy, with an ORR of 44.3%. All subtypes benefited well, and the ORR of common subtypes exceeded 40%. More than 50% of the patients with tumor remission achieved a complete response with a CRR of 23.9%. Per IRC assessment, the median duration of response (mDoR) reached 20.7 months. As of February 2024, golidocitinib showed a median overall survival (mOS) of 24.3 months. Golidocitinib was granted Fast Track Designation by the U.S. FDA for the treatment of r/r PTCL in February 2022. In September 2023, the CDE accepted its NDA and granted Priority Review for the treatment of r/r PTCL. The Phase I clinical data of golidocitinib( JACKPOT8 PART A) were published in Annals of Oncology (Impact Factor: 51.8), and global pivotal trial data of golidocitinib for the treatment of r/r PTCL (JACKPOT PART B) were published in The Lancet Oncology (Impact Factor: 54.4). **About DZD6008** DZD6008 is a novel, highly selective, full-BBB penetrant EGFR TKI, designed as a potential treatment option for advanced EGFR mutation positive (EGFRm) NSCLC. Non-small cell lung cancer is the leading cause of cancer death in the world. Epidermal growth factor receptor (EGFR) gene is one of the most common driver genes for NSCLC. Multiple agents can be used to treat patients with EGFR mutated NSCLC who develop resistance to EGFR tyrosine kinase inhibitors (TKIs), but the clinical outcome was not satisfactory. Brain metastases (BM) are a leading cause of death and disease progression for NSCLC. Approximately 23%-30% of NSCLC patients are synchronous BM at their initial diagnosis. Previous studies reported that the 3-year cumulative rate of BMs ranges from 29.4% to 60.3% in patients with mutated EGFR. Currently, the clinical benefits of existing treatments for third-generation EGFR TKI-resistant NSCLC are limited and DZD6008 is expected to fill the unmet medical needs. DZD6008 effectively inhibits EGFR-mutated tumor growth in cell lines and in animal models. Previous clinical studies have validated the design concept of the molecule and suggest that DZD6008 demonstrates good safety and efficacy in NSCLC patients with brain metastases who had failed third-generation EGFR TKI therapy or multiple lines of pre-treatments. **About Dizal** Dizal is a biopharmaceutical company, dedicated to the discovery, development and commercialization of differentiated therapeutics for the treatment of cancer and immunological diseases.
