PD-L1 Positive

Melanoma has emerged as the fastest-growing malignancy in recent years, with incidence and mortality rates among both men and women in East Asian countries exceeding the Asian average. China ranks fifth among East Asian nations in melanoma incidence. Currently, immune checkpoint inhibitors are achieving significant breakthroughs in adjuvant melanoma therapy. This study aims to evaluate the efficacy and safety of sintilimab combined with chemotherapy versus chemotherapy alone in patients with PD-L1-positive, completely resectable mucosal melanoma, thereby providing additional clinical evidence for treatment decisions.

This study is aimed to evaluate the efficacy and safety of Sacituzumab Tirumotecan combined with Toripalimab for first-line treatment of PD-L1 positive unresectable Locally Advanced/metastatic triple negative breast cancer (a/mTNBC).

This is an open-label, single-arm, multicenter phase II study to evaluate the safety and efficacy of sac-TMT plus Tagitanlimab in patients with PD-L1-positive locally advanced or metastatic TNBC.

A prospective, controlled Phase II clinical study on the efficacy and safety of the combination of limertinib and bevacizumab versus limertinib monotherapy as first - line treatment for locally advanced or recurrent metastatic non - squamous NSCLC with EGFR mutations and high PD-L1 expression.

This study is a prospective, umbrella-design, Phase II clinical trial. Eligible participants with advanced or metastatic gastric cancer who are treatment-naïve for advanced-stage systemic therapy will undergo biomarker profiling (HER2, CLDN18.2, and PD-L1) via next-generation sequencing (NGS) or immunohistochemistry (IHC). Participants will be stratified into distinct molecular subtypes and assigned subtype-specific therapeutic regimens. The primary objectives are to assess treatment efficacy (e.g., objective response rate) and safety profiles across molecularly defined cohorts.
