"Lymphedema can have long-lasting deleterious effects and can significantly impact quality of life. There is no FDA approved pharmacologic treatment. Currently, patients must rely on physical therapies such as manual lymph drainage and compression garments for relief," said Joanne Quan, MD, Chief Medical Officer at Eiger BioPharmaceuticals. "The ULTRA study is designed to explore a novel approach to the treatment of secondary lymphedema by blocking the production of LTB4. This approach has the potential to lessen the effects of this serious and debilitating disease and provide an convenient treatment option for patients."
About the ULTRA Phase 2 Study
ULTRA is a multi-center, randomized, double-blind, placebo-controlled Phase 2 study of ubenimex in patients with secondary lymphedema of the lower limb(s). Approximately forty patients will be randomized in a 1:1 ratio to receive ubenimex or matching placebo, administered orally for a total of 24 weeks. The 24-week study will assess clinical, biomarker, histologic and patient-reported outcomes.
About LTB4 and Ubenimex
Leukotriene B4 (LTB4) is a naturally-occurring inflammatory substance known to be elevated in both preclinical models of secondary lymphedema as well as human lymphedema disease. Elevated LTB4 causes inflammation resulting in tissue inflammation and impaired lymphatic function. Targeted pharmacologic inhibition of LTB4 promotes lymphatic repair and reverses lymphedema disease in treated animals.
Ubenimex is a well-characterized, oral, small-molecule, inhibitor of leukotriene A4 hydrolase (LTA4H), the enzyme responsible for the formation of the pro-inflammatory mediator, LTB4.
Ubenimex is approved in Japan (brand name Bestatin™) as an adjunct to chemotherapy agents to extend survival and to maintain remission after treatment for acute non-lymphocytic leukemia in adults. Ubenimex has been used for over 25 years in Japan and remains commercially available through Nippon Kayaku. Ubenimex is not approved for any indication in the US or Europe.
Lymphedema can be either primary (hereditary) or secondary (caused by another disease or condition). Primary lymphedema is caused by the absence of certain lymph vessels at birth or abnormalities in the lymphatic vessels and can be divided into three forms, depending on age of onset. Secondary lymphedema usually develops as a result of a lymph vessel blockage or interruption that alters the flow of lymph through the lymphatic system and can develop from an infection, malignancy, surgery, scar tissue formation, trauma, radiation, or other cancer treatment. Primary lymphedema and secondary lymphedema are large unmet medical needs, as both can be debilitating and negatively impact quality of life. There is no approved pharmacologic treatment for lymphedema.
Eiger is a clinical-stage biopharmaceutical company committed to bringing to market novel products for the treatment of rare diseases. The company has built a diverse portfolio of well-characterized product candidates with the potential to address diseases for which the unmet medical need is high, the biology for treatment is clear, and for which an effective therapy is urgently needed.
