Leukotriene Inhibitor
Zafirlukast for Ovarian Cancer
Phase 2
Recruiting
Led By Jeffrey Zwicker, MD
Research Sponsored by Beth Israel Deaconess Medical Center
Eligibility Criteria Checklist
Specific guidelines that determine who can or cannot participate in a clinical trial Must have
Minimum age ≥ 18 years. Because no dosing or adverse event data are currently available on the use of zafirlukast in participants under 18 years of age with ovarian cancer, children are excluded from this study but will be eligible for future pediatric trials.
Participants must meet criteria for tumor marker-only relapse, defined as CA-125 more than twice the upper limit of normal (35 U/mL) in the setting of a normal baseline CA-125 levels or CA-125 greater than twice the nadir count on two successive measurements for CA-125 values that remain above baseline without measurable radiographic disease.
Must not have
Pregnant women are excluded from this study because zafirlukast is a class B agent with the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with zafirlukast, breastfeeding should be discontinued if the mother is treated with zafirlukast.
Currently receiving anticoagulant therapy.

Summary
This trial is testing Zafirlukast, an asthma medication, to see if it can help patients with relapsed ovarian cancer. The drug may reduce tumor activity and lower the risk of blood clots based on lab studies. Zafirlukast is commonly used to improve asthma control.
Who is the study for?
This trial is for adult women with a specific type of ovarian cancer that has relapsed, indicated only by tumor markers without visible disease. They must have finished initial chemotherapy and surgery successfully, be able to swallow pills, and use contraception if childbearing potential. Men and those with certain health conditions or on conflicting medications are excluded.
What is being tested?
The study tests Zafirlukast's effectiveness in preventing tumor activity in women whose ovarian cancer has returned but is only detectable through tumor markers rather than physical tumors. Participants will take Zafirlukast tablets to see if it can control the cancer's return.
What are the potential side effects?
Zafirlukast may cause allergic reactions in some people similar to other drugs they might be allergic to. It could also potentially affect fetal development; hence pregnant women cannot participate. Other side effects are not detailed here.

Other Research
Common treatments for ovarian cancer include platinum-based chemotherapy, which works by causing DNA damage that leads to cancer cell death, and targeted therapies like PARP inhibitors, which prevent cancer cells from repairing DNA damage. Bevacizumab, an angiogenesis inhibitor, blocks the blood supply to tumors, inhibiting their growth.
Zafirlukast, a leukotriene receptor antagonist, is being studied for its potential to prevent tumor activity by blocking leukotriene pathways involved in inflammation and cancer progression. Understanding these mechanisms is crucial for ovarian cancer patients as it helps in selecting the most effective treatment based on the tumor's specific characteristics and resistance patterns.
