Non-Small Cell Lung Carcinoma (NSCLC)

This is a single-center pharmacokinetic study evaluating the impact of residual pembrolizumab levels on the efficacy of salvage chemotherapy following immunotherapy in patients with non-small cell lung cancer (NSCLC) or recurrent and/or metastatic head and neck squamous cell carcinoma (HNSCC) not amenable to curative local treatment.

The goal of this clinical trial is to learn if Trastuzumab Rezetecan can treat advanced solid tumors with HER-2 expression in adult participants. The main question it aims to answer is: What is the objective response rate of Trastuzumab Rezetecan in adult patients with HER-2 expressed advanced solid tumors? Participants will receive intravenous infusion of Trastuzumab Rezetecan on Day 1 of each 21-day treatment cycle. The dosage is 4.8 mg/kg per cycle; participants with a body weight of 85 kg or above will receive a fixed dose of 408 mg every 3 weeks.

Evidence suggests that appropriately selected older adults can tolerate standard-dose chemotherapy and achieve survival outcomes comparable to younger patients. However, older adults are usually under-represented in clinical trials and often receive reduced doses of chemotherapy due to concerns regarding age-related frailty, polypharmacy, and toxicity. This study seeks to evaluate chemotherapy dosing patterns and associated survival outcomes in older patients.

This Phase III, randomized, double-blind study compares the efficacy and safety of SCTB14 versus pembrolizumab as first-line treatment in patients with driver gene-negative, TPS ≥10% locally advanced or metastatic non-small cell lung cancer (NSCLC). The primary objective is to assess superiority of SCTB14 over pembrolizumab in prolonging progression-free survival. Safety will be closely monitored.
