A Study of Additional Chemotherapy After Surgery for People With Malignant Peritoneal Mesothelioma

July 20, 2026 updated by: Memorial Sloan Kettering Cancer Center

ICARuS II (Intraperitoneal Chemotherapy After cytoReductive Surgery): A Multicenter, Randomized Phase II Trial of Normothermic Intraperitoneal Chemotherapy and Intravenous Chemotherapy After Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy for Malignant Peritoneal Mesothelioma

The purpose of this study is to find out whether intraperitoneal or intravenous chemotherapy given after cytoreductive surgery and HIPEC are effective treatments for people with malignant peritoneal mesothelioma. Outcomes will be compared by observing intraperitoneal versus intravenous treatments to analyze if one is better than the other.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Patient age 18 years or older, both sexes.
  • Clinical diagnosis of MPM at enrolling institution.
  • Prior to randomization, intraoperative pathologic confirmation of epithelioid MPM at enrolling institution.
  • Complete or near-complete CRS achieved.
  • Patient must be planning to undergo complete cytoreduction of all peritoneal disease.
  • ECOG performance status ≤ 1.
  • Hematology: ANC ≥ 1,500/µl.
  • Platelets > 75,000/µl.
  • Adequate renal function: creatinine < 1.5× the upper limit of normal (ULN) or calculated creatinine clearance of ≥50 ml/min.
  • Adequate hepatic function: bilirubin < 1.5 mg/dl (except in patients with Gilbert's syndrome, who must have total bilirubin < 3.0 mg/dL).
  • Women of childbearing potential with a negative pregnancy test result (urine or blood) who agree to use an effective contraceptive method. Reliable contraception should be used from trial screening and must be continued throughout the study. A woman of childbearing potential is defined as one who is biologically capable of becoming pregnant.
  • A man participating in this study must agree to utilize a reliable barrier form of contraception for the duration of the study
  • Signed and dated written informed consent to participate in this clinical trial must be obtained prior to any study procedure.

Exclusion Criteria:

  • Subjects who have previously undergone intraperitoneal chemotherapy or systemic chemotherapy for peritoneal mesothelioma.
  • Subjects who have previously received platinum-containing chemotherapy regimens.
  • Subjects with preoperative or intraoperative biopsy consistent with sarcomatoid mesothelioma, well-differentiated papillary mesothelioma, or benign multicystic mesothelioma.
  • Other prior malignancies, except for cured non-melanoma skin cancer, curatively treated in situ carcinoma of the cervix, adequately treated malignancies for which there has been no evidence of activity for more than three years, or indolent tumors for which observation over two years is a reasonable option.
  • High suspicion for extra-abdominal metastases.
  • Women who are pregnant or lactating.
  • Active coronary artery disease (defined as unstable angina or a positive cardiac stress test). Subjects with a history of coronary artery disease may be included if they have had a normal stress test within 60 days of enrollment or are determined by a cardiologist to be of acceptable perioperative risk.
  • Uncontrolled hypertension defined as >140/90 and not cleared for surgery at the time of consent.
  • New York Heart Association (NYHA) Class II or higher congestive heart failure; restrictive or obstructive pulmonary disease that would limit study compliance or place the patient at unacceptable risk for participation in the study.
  • History of cerebrovascular disease that would limit study compliance or place the patient at unacceptable risk for participation in the study.
  • Subjects with other concurrent severe medical problems unrelated to the malignancy that would significantly limit full compliance with the study or place them at an unacceptable risk for participation in the study.
  • Patients with known cisplatin, carboplatin, pemetrexed or mitomycin allergy.
  • Evidence of extensive intraperitoneal adhesions at the time of surgery which prohibits intraperitoneal therapy, as determined by the operating surgeon.
  • Any condition that would preclude the ability to deliver appropriate IP therapy.
  • Use of an oral medication, lacking a suitable non-oral substitute, that if held for up to ten days, would be felt an unacceptable risk by the investigator.
  • Life expectancy < 12 weeks.

Experimental: IVC arm
Pemetrexed and cisplatin will be administered intravenously for a total of 4 to 6 cycles. Participants will receive 4 cycles, but can receive up to 6 cycles based on clinician discretion. Substitution with carboplatin allowed for pre-existing impairment of hearing, renal function, or neuropathy.
Drug: Pemetrexed
Pemetrexed will be administered intravenously
Drug: Cisplatin
Cisplatin will be administered intravenously
Drug: Carboplatin
Possible substitution with carboplatin based on clinician discretion
Active Comparator: NIPC arm
After completion of hyperthermic intraperitoneal chemotherapy/HIPEC, an intraperitoneal catheter with a subcutaneous reservoir will be inserted through the abdominal wall. When the participant's condition is considered stable by the physicians, the NIPC will be started. Pemetrexed and either cisplatin or carboplatin will be administered through the intraperitoneal port.
Drug: Pemetrexed
Pemetrexed will be administered intravenously
Drug: Cisplatin
Cisplatin will be administered intravenously
Drug: Carboplatin
Possible substitution with carboplatin based on clinician discretion
