Inclusion criteria
. Able to understand and voluntarily sign the written informed consent form;
. Age ≥18 years and ≤75 years;
. Histologically or pathologically confirmed epithelial malignant solid tumors,including: advanced gastric cancer and colorectal cancer that have failed at least two lines of treatment (treatment failure is defined as progression after treatment or intolerance after treatment); or platinum-resistant (platinum-efractory) dvanced ovarian cancer;
. Pathologically or clinically diagnosed with malignant ascites, and treatment for malignant ascites is required as judged by the investigator; B-mode ultrasound confirms that the volume of ascites is moderate or above (moderate or above ascites is defined as the maximum depth of ascites by B-mode ultrasound in supine position is ≥ 4.5 cm, or the actual amount of ascites drained is ≥ 1 L;
. The time interval between the last anti-tumor treatment and Randomization should meet the following time intervals:
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring

PuFS
Timeframe: Time from the end of drainage of ascites at C1V4 to the start of the next drainage or death (up to 6 months)
. Intraperitoneal therapy: The time from the most recent intraperitoneal infusion therapy to randomization should be ≥ 2 weeks;
. Systemic treatment: No washout required;
. AEs should have recovered to Grade ≤ 1 from previous treatment (except for other adverse reactions (such as alopecia) that do not affect the safety evaluation of the investigational drug as judged by the investigator according to NCI-CTCAE V5.0);
Exclusion criteria
. Patients with a known history of allergy to M701 or its components; patients with a known history of allergy to macromolecular ntibody drugs or a history of specific allergic reactions (asthma, rubella, and eczematous dermatitis);
. Have previously used M701, or have used antibody drugs targeting EpCAM and/or CD3 within 4 months before the first dose;
. Patients with central nervous system (CNS) metastases resulting in clinical symptoms or requiring therapeutic intervention; patients with previously treated brain metastases can be enrolled if they are asymptomatic and have stable disease as indicated by imaging examination ≥ 4 weeks before the first dose and do not require corticosteroids or anticonvulsant therapy;
. Have undergone major surgery within 4 weeks prior to randomization or plan to undergo major surgery during the study(excluding exploratory surgery);
. New or concurrent infection within 14 days prior to randomization that has not been controlled to clinical stability;
. Patients with severe respiratory diseases at screening, leading to respiratory failure or those judged by the investigator to be unsuitable for enrollment;
. Patients with active autoimmune diseases (e.g., inflammatory bowel disease,idiopathic thrombocytopenic purpura, lupus rythematosus, autoimmune hemolytic anemia, scleroderma, severe psoriasis, and rheumatoid arthritis), but patients with the following conditions are allowed to be screened: type I diabetes;hypothyroidism that can be controlled by replacement therapy only; skin diseases that do not require systemic treatment (e.g., vitiligo, psoriasis, and alopecia);
. Patients with severe cardiovascular and cerebrovascular diseases at screening,including cardiac insufficiency (NYHA Class III-IV); acute cardiovascular and cerebrovascular events (acute myocardial infarction, acute cerebral infarction,unstable angina, cerebral hemorrhage, etc.) orundergone vascular stenting within 6 months(Coronary artery stent implantation, intracranial artery stent implantation,etc.) or pulmonary embolism within the past 6 months; or venous thrombotic diseases such as venous thrombosis in lower limb within the past month;
