Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are adults aged 18 and older with a clinical diagnosis of malignant peritoneal mesothelioma who are planning to undergo complete cytoreduction.

Probably not a fit

Patients who have not achieved complete or near-complete cytoreduction or those with significant comorbidities may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study investigates the effectiveness of intraperitoneal versus intravenous chemotherapy administered after cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (HIPEC) for patients with malignant peritoneal mesothelioma. Participants will receive either pemetrexed, cisplatin, or carboplatin as part of their treatment regimen. The outcomes of both treatment approaches will be compared to determine which method yields better results in managing this aggressive cancer.

Why it matters

Potential benefit: If successful, this study could provide a more effective treatment option for patients with malignant peritoneal mesothelioma, potentially improving survival rates.

How similar studies have gone: Other studies have shown promise in using chemotherapy after surgery for similar conditions, suggesting that this approach may be beneficial.

Show full inclusion / exclusion criteria
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/immunotherapy 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.
