Active clinical trials for "Carcinoma"

To evaluate the efficacy and safety of HAIC combined with Cadonilimab and bevacizumab as first-line therapy in Unresectable hepatocellular carcinoma

This is a phase II prospective study to evaluate the safety and efficacy of Tislelizumab monotherapy or combined with lenvatinib as neoadjuvant therapy for resectable hepatocellular carcinoma.

To evaluate the safety and prognostic imaging factors of regorofenib in advanced second-line therapy; 3, to explore whether it is necessary to increase the treatment of TACE in the second-line treatment of advanced HCC.

A retrospective observational study to evaluate immunohistochemical expression of Inhibin Beta A (INHBA) in 60 cases of Colorectal Carcinoma, and compare levels of its expression to different clinicopathological criteria.

Phase 1 study evaluating the safety and efficacy of BRG01 in subjects with relapsed/ metastatic EBV-positive nasopharyngeal carcinoma (NPC). BRG01 is a Chimeric Antigen Receptor T-Cell therapy targetting on the specific protein of EBV, which is expressed on the EBV associated cancer cells. This study adopts the traditional "3+3" dose escalation design. Approximately12~18 EBV+ NPC subjects will be enrolled to evaluate the safety of BRG01. An internal safety review team (SRT) will review the safety data and make recommendations on further study conduct and progression to subsequential cohorts. Subjects will be enrolled into 3 cohorts of different doses, designated as cohort A, B and C.Cohort A: 3.0x10^6 CAR-T cells/kg,3 subjects, Cohort B: 9.0x10^6 CAR-T cells/kg,3 subjects, and Cohort C:1.5x10^7 CAR-T cells /kg, 6 subjects,respectively. Subjects in each cohort will follow the same treatment schedule and procedural requirements.

Comparative analysis of patients with resectable locally advanced esophageal squamous cell carcinoma treated with neoadjuvant chemotherapy or neoadjuvant chemoradiotherapy combined sintilimab versus neoadjuvant chemoradiotherapy.

The purpose of this study is to observe and evaluate the efficacy and safety of Decitabine plus Penpulimab as second-line therapy for advanced esophageal squamous cell carcinoma treated with PD-1 blockade

At present, the treatment regimen of locally advanced nasopharyngeal carcinoma still needs to be further improved, and the focus of improvement lies in "replacing cisplatin with high-efficiency and low-toxicity treatment regimen". Considering the synergistic effect among radiotherapy, immunotherapy and anti-angiogenesis therapy, we chose PD-1 inhibitor combined with bevacizumab to replace cisplatin chemotherapy.

This prospective observational study will evaluate the efficacy and safety of anlotinib in combination with Penpulimab in elderly patients with lung cancer. Data will be collected from each patient at baseline and after 4-6 cycles of therapy.

In the current literature, infection with the hepatitis B virus (HBV) is described as one of the main risk factors for the development of hepatocellular carcinoma (HCC). According to the current study situation, the Hepatitis B surface antigen (HBsAg) is considered as an important marker, since low levels and sero-clearance of HBsAg are both correlated with a lower risk of HCC development / recurrence.Currently there is no treatment option available that efficiently targets HBsAg. Besides neutralizing infectious HBV virions, Hepatitis B immunoglobulins (HBIG) can directly bind and neutralize extracellular HBsAg/SVPs, and even intracellular HBsAg targeting is reported. In addition, HBIGs can initiate effector-cell attack (via antibody-dependent cellular cytotoxicity, ADCC) towards infected hepatocytes. The potential benefit of HBIGs in the HCC context is further underlined by recent evidence for the ability of HBIGs to reduce the viability, proliferation, and self-renewal of tumor-initiating cells (TICs) - isolated from HBV-HCC patients - accompanied by downregulation of stemness markers, e.g., OCT-4.According to the current study situation, the use of HBIGs significantly reduces the risk of HBV reinfection after transplantation and improves the results of liver transplantation in patients with chronic HBV infection. The potential benefit of treating HBV-HCC patients on the LTx (liver transplantation) waiting list with hepatitis B immunoglobulin is the possible stop or inhibition of tumor progression while waiting for an LTx. So far there is no clinical evidence of this. Mechanistically, hepatitis B immunoglobulin could occur through neutralization of circulating HBsAg, which is an important driver of an immunosuppressive environment in HBV patients, and possibly through direct effects against HBV HCC tumor cells (through antibody-dependent cellular cytotoxicity, ADCC). Therefore, the idea behind preoperative HBIG administration before liver transplantation is to reduce the rate of patients in whom a transplantation would no longer have been possible due to tumor progression. Thus, due to tumor progression in HBV-positive HCC-patients there is a monthly drop-out from the waiting list of about 4%. The basic idea behind the treatment of HBV-HCC patients before tumor resection with hepatitis B immunoglobulin is to potentially stop or positively influence tumor progression through the effects mentioned above, in the time between diagnosis and resection. Zhou et al. (2015) have shown a connection between HBsAg levels and HCC relapses after resection, although the exact role of HBsAg is still unclear. In no case will the treatment postpone the time of tumor resection, as only patients are considered who, for clinical reasons, can expect a certain time until resection. The present proof of concept study aims to quantify HBsAg reduction due to preoperative administration of HBIGs in HBV-positive HCC-patients and serve as a template for future multicentre clinical trials.
