Rice bran arabinoylan compound study

This study is examining if a rice bran supplement improves the quality of life of cancer patients during treatment.

Rice bran arabinoxylan compound (RBAC) is a food supplement known to affect the body’s ability to defend against germs and cancerous cells.

During cancer treatment, RBAC may also help to reduce side effects, make patients feel better, and may improve treatment results.

However, there hasn't been enough research done to prove this. This study will examine whether RBAC does provide benefits during cancer treatment.

What does the clinical trial involve?

Researchers are seeking participants who are aged 18 years or older, who have been diagnosed with cancer (stage II and above) and are currently receiving cancer treatment.

Participants will take either the supplement or dummy powder for six months and will also be asked to complete the following items five times during the study:

  • Online questionnaires
  • blood tests
  • body scans
  • stool sample collections

How can people take part in the clinical trial?
