No results posted yet for this study

Summary

The purpose of the research is to determine the highest dose of an oral compound called zeaxanthin that can be safely taken each day in patients with advanced cancer, the toxicity profile of zeaxanthin, and the dose of zeaxanthin to use in future cancer clinical trials.

Conditions

  • Cancer Metastatic
  • Metastatic Solid Tumor

Interventions

BIOLOGICAL

Zeaxanthin

The doses of zeaxanthin will be based on weight starting with 2 milligrams of zeaxanthin per kilogram of your body weight (mg/kg) followed by 4 mg/kg, 6 mg/kg, and finally 8 mg/kg. If a dose level is found to be unsafe, then a new group of patients will be treated at the midpoint dose between the not tolerated dose and the last tolerated dose. Zeaxanthin is supplied as 50 milligram capsules and a person's dose will be rounded to the nearest 50 milligrams.

COMBINATION_PRODUCT

Zeaxanthin Plus Pembrolizumab

The doses of zeaxanthin will be based on weight starting with 2 milligrams of zeaxanthin per kilogram of your body weight (mg/kg) followed by 4 mg/kg, 6 mg/kg, and finally 8 mg/kg. If a dose level is found to be unsafe, then a new group of patients will be treated at the midpoint dose between the not tolerated dose and the last tolerated dose. Zeaxanthin is supplied as 50 milligram capsules and a person's dose will be rounded to the nearest 50 milligrams. The dose of pembrolizumab will be administered at a fixed dose of 400 milligrams intravenous every 6 weeks which is an FDA approved dosing schedule to treat cancer patients with pembrolizumab.
