About this study
Official title: A Randomized Phase 2 Trial of Flat Dose vs. Weight-based Dose of Intra-peritoneal (IP) Chemotherapy for Patients Undergoing Cytoreductive Surgery and Heated Intra-peritoneal Chemotherapy (CRS/HIPEC) for Advanced Gastrointestinal Malignancy
Peritoneal carcinomatosis from advanced gastro-intestinal malignancy has historically been associated with poor overall survival (≤ 12 months) with few treatment options. Cytoreductive surgery (CRS), which involves removal of all macroscopic tumor nodules, combined with direct administration of heated intra-peritoneal (IP) chemotherapy (HIPEC) to the affected peritoneal surfaces, has been shown to be an effective treatment option that extends overall survival among certain cases of peritoneal carcinomatosis. IP chemotherapy allows delivery of a high dose of cytostatic drug directly onto the peritoneal surfaces at risk for microscopic residual disease while systemic exposure remains limited. Additionally, hyperthermia is known to enhance the cytotoxicity of several agents (including Mitomycin C) and improves the depth of peritoneal penetration.
This trial will be a randomized phase 2 comparison of flat dose versus weight-based dose Mitomycin C. The hypothesis of this study is that HIPEC weight-based dosing may result in similarly effective peritoneal Mitomycin C concentrations with less systemic absorption and potential systemic toxicity, compared with the HIPEC flat dosing approach in patients undergoing CRS/HIPEC.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Mitomycin C, flat dose 40 mgDrug
Mitomycin C will be delivered as heated intraperitoneal chemotherapy (HIPEC) in two flat doses. Dose 1 will be 30mg at minute 0 and dose 2 will be 10 mg at minute 45.
Mitomycin C, weight-based dose 12.5 mg/m2Drug
Mitomycin C will be delivered as heated intraperitoneal chemotherapy (HIPEC) in two weight-based doses of 9.5 mg/m2 at minute 0 and 3 mg/m2 at minute 45.
| Study group | Role | What they receive |
|---|---|---|
| Flat Dose Mitomycin C | Experimental | Participants in this group will receive flat doses of mitomycin C intra-operatively: 1) 30mg at minute 0 and 2) 10mg at minute 45. Mitomycin C will be delivered via HIPEC (hyperthermic intraperitoneal chemotherapy). Receives: Drug: Mitomycin C, flat dose 40 mg |
| Weight-Based Mitomycin C | Experimental | Participants in this group will receive weight-based dosing of mitomycin C intra-operatively: 1) 9.5 mg/m2 at minute 0 and 2) 3 mg/m2 at minute 45 for total dose of 12.5 mg/m2. Mitomycin C will be delivered via HIPEC (hyperthermic intraperitoneal chemotherapy). Receives: Drug: Mitomycin C, weight-based dose 12.5 mg/m2 |
What is being measured
The primary outcome is the main question the study is designed to answer.
Area Under the Curve (AUC) - Pharmacokinetics
Drug exposure will be measured by calculating the area under the curve (AUC) or integral of a plasma concentration-time curve. Samples will be collected at 0,15, 30, 60 and 90 minutes intra-operatively, and 2, 4, and 12 hours postoperatively.
Measured: Approximately 20 hours
Drug Clearance (CL) - Pharmacokinetics
Drug clearance will be calculated as the volume of plasma cleared per unit time. Samples will be collected at 0,15, 30, 60 and 90 minutes intra-operatively, and 2, 4, and 12 hours postoperatively.
Measured: Approximately 20 hours
Drug Half-Life (T1/2) - Pharmacokinetics
Drug half-life will be calculated as the time required for the plasma Mitomycin C concentration to be half of its maximum concentration. Samples will be collected at 0,15, 30, 60 and 90 minutes intra-operatively, and 2, 4, and 12 hours postoperatively.
Measured: Approximately 20 hours

The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 1 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Prakash Pandalai, MD (859-323-8920, Prakash.Pandalai@uky.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Area Under the Curve (AUC) - Pharmacokinetics (time frame: Approximately 20 hours). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04779554, which also lists 1 linked publication.

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Apr 2026.
