Clinical trials

This study adopts a combined design of retrospective cohort study followed by prospective observational study, which is conducted at Beijing Chest Hospital. The study first collects and analyzes the data of intestinal tuberculosis patients diagnosed and followed up in the hospital from 2011-1 to 2025-12 (a 15-year retrospective period) as the retrospective cohort, aiming to initially identify the risk factors associated with mortality in patients with intestinal tuberculosis. On the basis of the retrospective analysis results, the study will further carry out a prospective observational study, continuously enroll new intestinal tuberculosis patients, follow up their clinical status, treatment response and mortality outcomes for a certain period, and verify and supplement the risk factors identified in the retrospective stage. Clinical data, including demographic characteristics, clinical manifestations, laboratory test results, treatment regimens, and follow-up outcomes (mortality status), will be collected and sorted out in both stages. Univariate and multivariate statistical analyses will be used to screen and verify potential risk factors (such as age, disease severity, comorbidities, and treatment compliance) that affect the mortality of patients with intestinal tuberculosis. The results of this study are expected to provide scientific evidence for optimizing the clinical management, risk assessment, and prognostic improvement of patients with intestinal tuberculosis, and further guide the formulation of targeted prevention and treatment strategies.

Current studies confirmed that the immune perioperative treatment with combination chemotherapy curative effect and safety of resectable NSCLC, but its short-term curative effect and long-term survival benefit remains to be further improved to explore the new way of immune combination therapy. Experimental study showed that the inhibition of PCSK9 could significantly increase in tumor cells of the immune response in mice, inhibit the PCSK9 enhanced anti-tumor immune response of mice can be further coordinate with immune checkpoint therapy, forming a lasting anti-tumor immune effect. There are no reports on the peri-operative treatment of immune combined with chemotherapy and PCSK-9 inhibitors in patients with resectable NSCLC. Based on the above, the aim of this study is to explore the efficacy and safety of Adebrelimab combined with recaticimab and chemotherapy in the perioperative treatment of patients with resectable NSCLC.

This is an open-label, non-randomized, controlled, single-center, phase II study to compare the efficacy and safety of neoadjuvant PD-L1/PD-1 inhibitor + chemotherapy (carboplatin/cisplatin + etoposide) with chemotherapy (carboplatin/cisplatin + etoposide) alone followed by radical surgery and adjuvant treatment as perioperative therapy in patients with limited-stage SCLC.
