Active clinical trials for "Digestive System Neoplasms"

The study is a randomized study of patients living in four municipalities in Eastern Jutland. After geriatric assessment half of the patients will be offered a tailor-made intervention in their homes. The follow-up will last for at least 90 days and include treatment of the patients' multimorbidity, e.g. of dehydration, anaemia, infections, and malnutrition. The other half of the patients, the results of the assessment and recommendations will be given to the patients and their general practitioner. The primary efficacy variables are accomplishment of planned cancer treatment, reduction of complications and admissions to hospital and increased quality of life,. If geriatric assessment and a tailor-made follow-up result in a better quality of life with less complications and admissions the offer may be extended to a longer period, younger age groups and other cancer diagnoses.

The purpose of this study is to evaluate the safety and efficacy of chemotherapy combined with autologous tumor Lysate-pulsed dendritic with cytokine-induced killer cell (Ag-D-CIK) for gastric cancer.

This is a multi-center, open label, repeat dose, Phase 1 study consisting of a Dose Escalation Phase and a Dose Expansion Phase to evaluate safety, pharmacokinetics, and clinical activity.

LP002 is a humanized monoclonal antibody targeting programmed death ligand-1 (PD-L1), which prevents PD-L1 from binding to PD-1 and B7.1 receptors on T cell surface, restores T cell activity, thus enhancing immune response and has potential to treat various types of tumors. In this study, the safety, pharmacokinetics and preliminary efficacy of LP002 for the treatment of malignant digestive system neoplasms will be evaluated.

Targeting human epidermal factor receptor 2 (HER2) therapy have shown the anti-tumor efficacy in patients with HER2-positive gastrointestinal tumors. Pyrotinib is an irreversible small-molecule receptor tyrosine kinase inhibitor targeting both epidermal growth factor receptor (EGFR) and HER2. This study is designed to evaluate the efficacy and safety of Pyrotinib in patients with HER2 positive gastrointestinal tumors.

Hepatocellular carcinoma (HCC) is the fourth most common cause of cancer-related death that ranks sixth in terms of incident cases, with an overall 5 years survival of 18%. Despite a significant improvement in treatment strategy, the overall survival of HCC remains low due to high recurrence, progressive liver dysfunction and the high fatality of the disease. Surgical resection has been applied in a number of patients; however, surgery has been associated with a high incidence of recurrence (approximately 70% within 5 years). TACE is generally applied on intermediate-stage HCC. However, TACE is not satisfied with improving overall survival. Therefore, there is an urgent need for effective treatment for these patients. At present, the overall objective response rate (ORR) of single or sequential therapy is not satisfied, and the over survival (OS) improvement is not ideal. Therefore, combined therapy maybe the good choice for patients with advanced HCC. This study focuses on the in-operable, BCLC-B/C HCC patients. Through the combination of local therapy (TACE), anti-angiogenic therapy (Sorafenib), and immunotherapy (PD-1 monoclonal antibody), it is expected to change the tumor microenvironment, restore the immune response, strengthen the anti-tumor effect of various treatments, and improve the therapeutic efficacy in patients with BCLC-B/C HCC.

This clinical study focused on patients with digestive system tumors resistant to PD-1 inhibitors, and explored the reversal resistance of epigenetic drugs (decitabine) and TKI drugs (anlotinib) in this part of patients.

This study evaluates the safety and efficacy of D-CIK immune cells combined with chemotherapy after resection of esophageal cancer

A phase III double-blind randomized clinical trial on the effects of ganoderma spore lipids to the immunological response in patients with G.I. Cancers. The trial is randomized, double-blind. Cancer patients are diagnosed based on pathology or cell biology. Patients are randomized into 2 groups: both groups receive chemotherapy. Either group receives ganoderma spore lipids or placebo capsules 600mg three times a day (TID) in addition to the chemotherapy. Clinical evaluation includes chemotherapy drug toxicities, life quality improvement. Blood biochemistry tests mainly include malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), adrenaline, nor-adrenaline, tumor necrosis factor (TNF)-α, interleukin (IL)-1b, interleukin (IL)-6, cell flow cytometry on Th1, Th2, Th17, Treg cytokines, as well as serum cortisol, estradiol (female), progesterone (female), testosterone (male), etc.

The aim of this non-interventional study is to evaluate the efficacy of a monofilament, mid-term absorbable suture material (Monosyn®) for anastomosis performed in the gastrointestinal tract using the frequency of anastomosis leakage as a primary parameter. Postoperative complication rate, length of hospital stay, costs, time to perform the anastomosis and handling will serve as secondary endpoints. The question is addressed, whether a monofilament suture material is as effective as a braided suture material for anastomosis construction within the gastrointestinal tract.
