A Study of Folate Levels in Patients Treated with Olaparib


This is a study looking at folate deficiency (lack of folic acid in the blood) in patients who take the drug olaparib (Lynparza) to treat their advanced ovarian or breast cancer. The main goal of this study is to measure how often and when folate deficiency is most likely to occur; and to learn more about whether giving folic acid supplements (vitamins) will help delay or avoid deficiency in these patients. Folate deficiency can cause side effects and lead to reduction or stopping of treatment with olaparib.

Study goals

The purpose of this study is to answer the following questions:

  • What percentage of subjects develop folic acid deficiency after starting treatment with olaparib?
  • How quickly does anemia develop after starting olaparib?
  • For subjects who develop folic acid deficiency while on olaparib, does folic acid supplementation improve anemia, decrease the need for blood transfusions and allow subjects to stay on olaparib without needing to receive a smaller dose or stopping treatment?
  • Does folic acid deficiency and folic acid supplementation impact the cancer response to olaparib?
  • Why does folic acid deficiency occur in subjects treated with olaparib?
