ZG005 in combination with etoposide and cisplatin for the first-line treatment of advanced neuroendocrine carcinoma (ESMO 2025) - P1/2 | "Background Advanced neuroendocrine carcinoma (NEC) has limited therapeutic options, with etoposide/cisplatin (EP) or etoposide/carboplatin (EC) remaining as the first-line standard. Serious adverse events occurred in 20.7% of pts in the ZG005+EP arms, with two cases (immune-mediated enterocolitis and subclinical myocarditis) deemed treatment-related. Conclusions The combination of ZG005 with standard EP based chemotherapy showed a favorable safety profile and encouraging anti-tumor activities in pts with NEC."

Preliminary results of ZG005, a bispecific antibody targeting PD-1 and TIGIT, in combination with chemotherapy with or without bevacizumab as first-line treatment for advanced cervical cancer. (ASCO 2025) - P1/2 | "In the Part 2, pts were randomized at 1:1 ratio to receive ZG005 at 10 mg/kg or 20 mg/kg in combination with the standard chemotherapy (paclitaxel [175 mg/m2] plus carboplatin [AUC 5] or cisplatin [50 mg/m2]), with or without bevacizumab (15 mg/kg) every 3 weeks for six cycles, followed by the maintenance therapy of ZG005 with or without bevacizumab for up to 2 years. ZG005 in combination with the chemotherapy, with or without bevacizumab, demonstrated favorable safety and tolerability profiles at both 10 mg/kg and 20 mg/kg dosages. Additionally, this regimen exhibited a significant antitumor activity in first-line cervical cancer pts, with the 20 mg/kg dose group showing a notably better efficacy in comparison with the 10 mg/kg dose group."
