Study Summary

This trial is testing whether iohexol can help doctors calculate the dose of carboplatin given to cancer patients.

Who is the study for?
This trial is for male cancer patients aged 18 or older who will receive carboplatin chemotherapy. They must be in good general health, able to follow the study plan, and provide informed consent. Men should use contraception as dictated by their treatment protocol. Women are not eligible due to study objectives.Check my eligibility
What is being tested?
The trial is testing how well iohexol helps calculate the correct dose of carboplatin for cancer treatment. It aims to improve dosing accuracy of carboplatin by studying its interaction with iohexol and collecting biospecimens from participants.See study design
What are the potential side effects?
Potential side effects may include allergic reactions related to iohexol (similar to those seen with CT contrast agents), issues affecting kidney function, and possible interference with thyroid gland activity.

Mechanism Of Action
Side Effect Profile
Prior Approvals
Other Research
Chemotherapy drugs, such as carboplatin, function by disrupting the DNA of cancer cells, thereby inhibiting their ability to divide and proliferate. This mechanism is vital for cancer patients as it targets rapidly growing tumor cells. Accurate dosing of these drugs is critical to enhance their effectiveness and minimize adverse effects. Iohexol aids in this by providing precise kidney function measurements, allowing for the optimization of carboplatin dosing tailored to each patient's renal function. This personalized dosing approach can lead to better treatment outcomes and reduced toxicity.
