Clinical trials

This study is a prospective, exploratory clinical study aimed at evaluating the feasibility and safety of camrelizumab combined with synchronous chemoradiotherapy as an organ-preserving strategy for locally advanced resectable esophageal squamous cell carcinoma. The study targets patients with locally advanced resectable stage II/III/IVa (cT1b-4aN0-3M0) ESCC. A total of 164 subjects are expected to be enrolled. The study is a randomized, non-controlled, open-label trial. Subjects meeting the inclusion criteria will be randomly assigned in a 1:1 ratio to receive either camrelizumab combined with radiotherapy, albumin-bound paclitaxel, and carboplatin treatment (Cohort 1) or camrelizumab combined with radiotherapy and capecitabine treatment (Cohort 2). The screening period for the study is 28 days. After completing screening examinations and assessments, eligible subjects will be randomly assigned to the following treatment regimens. Cohort 1: * Camrelizumab: 200 mg on Day 1, every 3 weeks * Radiotherapy: 50-50.4 Gy / 25-28 fractions, Days 1-5, once a week * Albumin-bound paclitaxel: IV infusion, 60-80 mg/m², Day 1, weekly * Carboplatin: IV infusion, AUC=1-1.5, Day 1, weekly Each cycle lasts 3 weeks, with 2-4 cycles of medication. Efficacy evaluation (imaging and endoscopic examination) will be conducted within 6 weeks after the completion of treatment. If the efficacy evaluation indicates cCR, subjects will enter Group A1 and receive camrelizumab maintenance therapy (maximum 1 year). If the efficacy evaluation does not reach cCR, after consultation between the investigator and the subject, they will enter Group B1 to undergo radical surgery, followed by camrelizumab monotherapy maintenance treatment (maximum 1 year). Cohort 2: Camrelizumab: ivgtt, 200 mg, D1, Q3W Radiotherapy: 50-50.4 Gy / 25-28 fractions, D1-D5, QW Capecitabine: p.o. 625 mg/m², BID, D1-D14, Q3W; One cycle lasts 3 weeks, with 2-4 cycles of medication. Efficacy evaluation (imaging and endoscopy) will be conducted within 6 weeks after treatment completion. If the efficacy is assessed as cCR, the patient will enter Group A2: receive camrelizumab maintenance therapy (up to 1 year); if efficacy is not cCR, the patient will enter Group B2: undergo radical surgery, followed by camrelizumab monotherapy maintenance (up to 1 year). This study will follow up subjects for disease recurrence and disease-free survival for at least 2 years. After all subjects complete the treatment/termination visit, efficacy will be evaluated.

The purpose of this study is to assess the efficacy and safety of QL1706 combined with nab-paclitaxel and cisplatin in first-line therapy for patients with advanced or metastatic esophageal squamous cell carcinoma. QL1706 is a anti-PD-1 and anti-CTLA4 antibody.

Primary Objectives: •To evaluate the safety and tolerability of a single dose of Exenatide Circular RNA-Lipid Nanoparticle Injection（CR059）in Chinese subjects with T2DM. Secondary Objectives: * To characterize the pharmacokinetic (PK) profile of a single dose of Exenatide Circular RNA-Lipid Nanoparticle Injection（CR059） in Chinese subjects with T2DM; * To characterize the pharmacodynamic (PD) profile of a single dose of Exenatide Circular RNA-Lipid Nanoparticle Injection（ CR059） in Chinese subjects with T2DM; * To evaluate the immunogenicity of a single dose of Exenatide Circular RNA-Lipid Nanoparticle Injection（ CR059） in Chinese subjects with T2DM; Participants : Diagnosed with T2DM for at least 3 months but less than 5 years, according to the Chinese Diabetes Society's diagnostic criteria

The aim of this study is to compare outcomes in Chinese patients with locally advanced resectable esophageal squamous cell cancer who have received either surgery or definitive chemoradiation (CRT) by the randomized, open-label, multicenter trial.

To assess the efficacy and safety of adebrelimab in combination with apatinib mesylate and chemoradiotherapy in immuno-experienced second-line esophageal squamous cell carcinoma (with symptomatic dysphagia or oligometastatic disease)，and to evaluate the efficacy and safety of adebrelimab in combination with apatinib mesylate and chemoradiotherapy in immuno-experienced second-line esophageal squamous cell carcinoma (without symptomatic dysphagia or oligometastatic disease).

Esophagectomy is an important means of radical treatment of esophageal cancer, but due to local recurrence and metastasis, the 5-year survival rate of patients with esophageal cancer is only 20-30%. Studies have reported that about 50% of patients relapse within 1 year after surgery, and the short-term recurrence rate is high. Therefore, reducing the recurrence rate of esophageal cancer after operation is an important way to improve its prognosis. Porphyromonas gingivalis infection in ESCC tissues was significantly higher than that in paracancer tissues, and was significantly positively correlated with cancer cell differentiation, lymph node metastasis, TNM stage, and shortened survival of ESCC patients. In summary, porphyromonas gingivalis plays an important role in postoperative recurrence of esophageal cancer. Elimination of porphyromonas gingivalis can significantly reduce the recurrence rate of esophageal cancer after operation. Tinidazole is a class of nitroimidazole drugs. It has been pointed out that the pharmacological mechanism of Tinidazole is to inhibit the DNA synthesis of pathogenic bacteria, so as to eliminate bacteria in periodontal tissues and inhibit local inflammation. Based on this, we designed and fabricated a novel oral microneedle patch loaded with tinidazole. Tinidazole oral microneedle patch can effectively remove porphyromonas gingivalis and promote the repair of gingival tissue. In this study, based on the combination of mechanical removal and antibacterial treatment, a combination of ultrasonic dental cleaning and tinidazole oral composite microneedle patch was designed to completely remove porphyromonas gingivalis in oral cavity, and to evaluate the effect of removal of porphyromonas gingivalis in oral cavity on the prognosis of esophageal cancer after radical surgery.
