Malignant Ascites

The goal of this clinical trial is to determine the safety and efficacy of of ACM-CpG for inoperable peritoneal metastases or malignant ascites. The main questions it aims to answer are: • To determine the safety and maximum tolerated dose (MTD) or optimal biologic dose (OBD) of intraperitoneal injection(s) of ACM-CpG for inoperable peritoneal metastases or malignant ascites? Researchers will assign treatment levels using escalating doses of ACM-CpG Therapy. Participants will: * Will receive at least one dose of ACM-CpG therapy on Day 1 of a 28-day treatment cycle. * May receive up to 2 additional injections if they have clinically stable or responsive disease. * Must visit the clinic on Days 1, 4, 7, 10, 14, 21, and 28 for checkups and tests. * Will have a CT scan or MRI performed every 8 weeks for 3 scans and then continue to receive scans every 12 weeks to monitor their disease.

Eligible subjects with advanced hepatocellular carcinoma and ovarian cancer will be divided into two treatment groups based on the volume of ascites. Group A consists of patients with mild ascites, who will receive NK521 via intravenous infusion. Group B includes patients with moderate to severe ascites, who will be treated with investigator-selected systemic regimens combined with intraperitoneal perfusion of NK521. Systemic and local medications will be administered in accordance with the treatment regimens of respective groups, and the safety of the study drug will be monitored. Preliminary anti-tumor efficacy will be assessed using the RECIST 1.1 criteria at Week 6 after the first infusion of NK521. Catheter placement and ascites drainage will be performed 3 days prior to the first intraperitoneal perfusion of NK521. After the initial intraperitoneal perfusion treatment, the therapeutic effect on ascites will be evaluated per the WHO criteria for ascites assessment.

This is a prospective, single-center, interventional, phase I, dose-escalation, single-arm study designed to evaluate the safety, tolerability, and preliminary efficacy of intrapleural/intraperitoneal infusion of WSK-IM02 in patients with advanced solid tumors complicated by malignant pleural or peritoneal effusions who have failed standard of care.

The goal of this study is to evaluate the change in symptoms for women with cancer-related malignant ascites who complete an at-home paracentesis procedure.

This study is a prospective, multi-cohort Phase Ib/II clinical trial, consisting of two stages as follows: 1. Phase Ib Dose-Escalation Stage To explore the dose-limiting toxicities (DLT) of intraperitoneally administered liposomal irinotecan in patients with malignant peritoneal effusion who have failed prior standard therapy, and to estimate the maximum tolerated dose (MTD) of the investigational agent. 2. Phase II Expansion Stage To evaluate the efficacy and safety of liposomal irinotecan as monotherapy or in combination with recombinant modified human tumor necrosis factor or bevacizumab, in the treatment of malignant peritoneal effusion in patients who have failed prior standard therapy.

Malignant Ascites is a common complication of malignant tumor. The objective of this study is to evaluate the safety, efficacy, and pharmacokinetic characteristics of intraperitoneal perfusion with Docetaxel Polymeric Micelles (SIM0388) for injection in patients with malignant ascites

The purpose of this study to find out if tocilizumab can be safely infused into chest or abdominal cavities of patients with malignancy ascites (MA) or malignant pleural effusions (MPE). Patients will have a total of 4 doses, one dose administered each week. Each dose will be greater than the previous one.

1. More than half of peritoneal metastases are from digestive tract. Peritoneal metastasis has poor prognosis, poor treatment response and limited means. 2. rmhTNF-NC or bevacizumab are effective in the treatment of malignant pleuroabdominal effusion. 3, There is increasing evidence that PD-1/PD-L1 inhibitors in combination with vascular endothelial growth factor receptor (VEGFR) inhibitors have a complementary mechanism of action: VEGF pathway inhibitors normalize blood vessels in tumors and promote immune cell maturation and infiltration, thus playing a synergistic role with ICIs. The strategy of systemic immunotherapy combined with antivascular therapy has been confirmed by several large phase III clinical trials such as IMbrave-150. Basic studies have confirmed that uncontrolled tumor vessels in peritoneal metastasis and malignant ascites microenvironment also play an important role in promoting disease progression. Therefore, this project intends to explore the treatment of malignant abdominal effusion by local intraperitoneal injection of bevacizumab and PD-1 on the basis of rmhTNF-NC
