  • Fanconi Anemia

Purpose:

Fanconi anemia (FA) is an autosomal recessive disease characterized by progressive bone marrow failure (BMF), congenital abnormalities and a predisposition to malignancy.


Study summary:

Current therapies for children with Fanconi anemia (FA) and bone marrow failure, i.e. androgens or bone marrow transplantation, are associated with significant morbidity and mortality. This is a pilot study aiming to assess feasibility, toxicity and pharmacokinetics of oral Quercetin therapy in patients with FA. This is a first step towards a clinical study of the efficacy of Quercetin therapy in delaying progression of BMF in FA. Additional correlative studies will include assessment of impact of Quercetin on reduction of Reactive Oxygen Species (ROS), maintenance or improvement of hematopoietic stem cell (HSC) reserve, improvement of hematopoiesis (i.e. peripheral counts) and insulin sensitivity/glucose tolerance. This study is an open-label single arm study. Funding Source - FDA OOPD Accrual closed for the main study. Expansion cohort added to observe additional patients at the desired dose. Expansion Cohort: The second and third cohort of participants completed the study treatment as expected, tolerating Quercetin well without any DLT. Based on the PK and ROS analyses, the dose was increased for the fourth cohort (subjects #10-12). To observe additional patients at the desired dose, an expansion cohort is being added. Up to 20 patients will be enrolled in the expansion cohort. The purpose of the expansion cohort is to assess the effects of quercetin supplement at the desired dose on clinical and biological endpoints. Patients in the expansion cohort will receive quercetin treatment for the first 26 weeks. Patients will be able to continue quercetin supplement after the completion of the study period of 26 weeks if they wish. If patients decide to continue quercetin after the first 26 weeks, quercetin will be provided by the investigational pharmacy for up to 1 year. Patients who continue quercetin supplement after 26 weeks, but discontinue quercetin before 1 year will be followed through the 1 year visit. Patients who discontinue quercetin supplement any time after the 1 year visit will be followed through the 2 year visit. Patients previously enrolled in the initial phase of the study (cohorts 1-4) may be considered for enrollment on the expansion cohort of the study provided they meet all inclusion and exclusion criteria.
