Core Viewpoint - The announcement highlights the clinical data and latest progress of ZG006 and ZG005, which will be presented at the 2025 ASCO annual meeting, indicating the company's ongoing commitment to advancing its innovative oncology therapies [1]. Group 1: ZG006 Overview - ZG006, also known as Alveltamig, is a trispecific antibody drug developed by the company and its subsidiary, Gensun Biopharma Inc., targeting DLL3 and CD3, and has received orphan drug designation from the FDA [1][2]. - ZG006 is the first-in-class molecule targeting DLL3, showing potential to be a best-in-class therapy [1]. Group 2: ZG006 Clinical Data - In the ZG006-002 study, 48 patients with refractory advanced small cell lung cancer were randomized to receive either 10 mg or 30 mg Q2W treatment, with objective response rates (ORR) of 62.5% and 58.3%, respectively [2][3]. - The disease control rates (DCR) were 70.8% for the 10 mg group and 66.7% for the 30 mg group, with safety profiles showing no treatment-related adverse events leading to permanent discontinuation [3]. - In the ZG006-001 study, 47 patients received varying doses of ZG006, with confirmed ORR of 75.0% for 10 mg, 53.8% for 30 mg, and 58.3% for 60 mg, indicating strong anti-tumor activity [4][5]. Group 3: ZG005 Overview - ZG005, known as Nilvanstomig, is a recombinant humanized bispecific antibody targeting PD-1 and TIGIT, positioned as an innovative immunotherapy for various solid tumors [6][7]. - ZG005 is among the first of its kind to enter clinical research globally, with no similar mechanism drugs approved yet [6]. Group 4: ZG005 Clinical Data - In the ZG005-001 study, 55 patients with advanced cervical cancer were treated, showing an ORR of 40.9% and DCR of 68.2% in the 20 mg/kg group [7]. - The safety profile was favorable, with 83.6% of patients experiencing treatment-related adverse events (TRAE), predominantly grade 1-2 [7]. - In the ZG005-003 study, 60 patients with first-line cervical cancer were treated, with the 20 mg/kg group showing an ORR of 82.1% and DCR of 96.4% [8][9]. Group 5: ZGGS15 Overview - ZGGS15 is a recombinant humanized bispecific antibody targeting LAG-3 and TIGIT, representing a novel approach in tumor immunotherapy [10][11]. - It is the first of its kind to enter clinical research globally, with no similar mechanism drugs approved yet [10]. Group 6: ZGGS15 Clinical Data - In the ZGGS15-001 study, 22 patients were enrolled, with a DCR of 35.3% among evaluable patients [12]. - The safety profile showed that 90.1% of patients experienced TRAE, with no dose-limiting toxicities observed [12][13].
