Phase II Study of the Effects of Laparoscopic Hyperthermic Intraperitoneal Chemotherapy (HIPEC) in Patients With Advanced Gastric Cancer

Recruiting now · Phase 2

Conditions studied: Gastric Cancer, Peritoneal Carcinomatosis

In brief

To assess if PD-L1 expression can be upregulated in peritoneal metastases from gastric cancer after the administration of HIPEC with greater frequency compared to systemic chemotherapy alone

Key facts

Study ID: NCT04107077
Run by: University of Chicago
People needed: 21
Starts: 2025-09-09
Expected to finish: 2030-06-01
Last updated by the study team: 2026-06-11

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

Patients with histologically confirmed GC/PM only and/or positive peritoneal cytology, who have completed prior systemic chemotherapy for a minimum of 2 to 4 months duration.
Age ≥18 years. Because no dosing or adverse event data are currently available on the use of HIPEC for GC/PM in patients under 18 years of age, children are excluded from this study, but will be eligible for future pediatric trials.
ECOG performance status ≤2 (Karnofsky ≥60%, see Appendix A).
Patients must have adequate organ and marrow function as defined below:
leukocytes ≥3,000/mcL
absolute neutrophil count ≥1,500/mcL
platelets ≥100,000/mcL
total bilirubin ≤ institutional upper limit of normal (ULN)
AST(SGOT)/ALT(SGPT) ≤3 × institutional ULN
creatinine ≤ institutional ULN OR
glomerular filtration rate (GFR) ≥50 mL/min/1.73 m2 unless data exists supporting safe use at lower kidney function values, no lower than 30 mL/min/1.73 m2 (see Appendix B).
Human immunodeficiency virus (HIV)-infected patients on effective anti-retroviral therapy with undetectable viral load within 6 months are eligible for this trial.
For patients with evidence of chronic hepatitis B virus (HBV) infection, the HBV viral load must be undetectable on suppressive therapy, if indicated.
Patients with a history of hepatitis C virus (HCV) infection must have been treated and cured. For patients with HCV infection who are currently on treatment, they are eligible if they have an undetectable HCV viral load.
Patients with a prior or concurrent malignancy whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessment of the investigational regimen are eligible for this trial.
Patients with known history or current symptoms of cardiac disease, or history of treatment with cardiotoxic agents, should have a clinical risk assessment of cardiac function using the New York Heart Association Functional Classification. To be eligible for this trial, patients should be class 2B or better.
Expected survival greater than 3 months.
Because cisplatin and Mitomycin C are pregnancy category D and potentially teratogenic, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately. Men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of study participation, and 4 months after completion of the study.
Ability to understand and the willingness to sign a written informed consent document.

You may not qualify if…

Patients with coexistence of another untreated malignant neoplasm other than basal cell carcinoma of the skin within the last five years.
Sites of metastases other than loco-regional lymph nodes and peritoneum (ex. Visceral metastases such as liver, lungs, bone, brain).
Patients who have not recovered from adverse events due to prior anti-cancer therapy (i.e., have residual toxicities > Grade 1) with the exception of alopecia.
Patients who are receiving any other investigational agents.
History of allergic reactions attributed to compounds of similar chemical or biologic composition to cisplatin and Mitomycin C.
Patients with uncontrolled intercurrent illness.
Patients with psychiatric illness/social situations that would limit compliance with study requirements.
Pregnant women are excluded from this study because cisplatin and Mitomycin C are class D agents with the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with cisplatin and Mitomycin C, breastfeeding should be discontinued if the mother is treated with cisplatin and Mitomycin C.
