Can cilastatin shield kidneys during ovarian cancer surgery?
NCT ID NCT07229040
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study compares two drugs, cilastatin and thiosulfate, for protecting the kidneys in women with ovarian cancer who undergo surgery with heated chemotherapy. About 90 patients will be randomly assigned to receive one of the drugs during the procedure. The main goal is to see which drug better prevents kidney injury in the week after surgery.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- cilastatin
- What this could lead to
- If cilastatin works better, it could offer a safer way to protect kidneys during heated chemotherapy for ovarian cancer.
- What could go wrong
- This is a small phase 2 trial, so results may not apply broadly. Also, both drugs have risks, and the study is only comparing kidney protection, not curing the cancer.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Age: adult patients aged 18-75 years. Sex: female. Eastern Cooperative Oncology Group Performance Status (ECOG PS) ≤ 2. General condition: patients eligible for major surgery, with creatinine, bilirubin, and blood count values within or close to the normal range (Hb \>10 g/dL, leukocytes \>3,000/mL, neutrophils \>1,000/mL, platelets \>100,000/mL). Patients evaluated by the Anesthesiology Department and deemed fit for surgery. Signed informed consent. Disease confined to the abdomen: CRS + HIPEC is not indicated in patients with pulmonary, bone, or other distant metastases. Patients with limited hematogenous metastases to the spleen or liver may be considered. Patients with regional or distant intra-abdominal lymphatic dissemination may also be considered, provided complete resection is feasible. FIGO stage IVA epithelial ovarian carcinoma at presentation, due to pleural effusion with mediastinal lymph node or splenic metastases, is an indication for neoadjuvant chemotherapy; if response is achieved, CRS + HIPEC may subsequently be considered. Multidisciplinary Committee evaluation: radiological PCI is assessed, and the likelihood of achieving complete cytoreduction is estimated to determine the indication for CRS + HIPEC. Exclusion Criteria: * Lack of consent to participate in the clinical trial. Eastern Cooperative Oncology Group Performance Status (ECOG PS) \> 2. Not eligible for major surgery. Disease not confined to the abdomen, or with findings indicating that optimal cytoreduction is not achievable (e.g., intestinal obstruction, biliary obstruction, ureteral obstruction, or diffuse involvement of the small bowel or mesentery). Known hypersensitivity to platinum-based agents.
