Leap Therapeutics Unveils Groundbreaking Research on FL-501
Leap Therapeutics, Inc. (NASDAQ: LPTX), a progressive biotechnology company focused on targeted therapies and immuno-oncology, is excited to announce its presentation of preclinical data on FL-501, an innovative GDF-15 neutralizing antibody. This event is set to take place at a prominent annual scientific gathering. FL-501 has shown transformative potential by fully restoring body composition and reversing prominent indicators of cachexia in preclinical models.
Significance of FL-501 in Cancer Cachexia Treatment
The findings underscore GDF-15's pivotal role in cachexia, a critical condition leading to severe weight loss and muscle wasting in cancer patients. Such a phenomenon significantly diminishes patients' quality of life and contributes to heightened cancer mortality rates. Jason Baum, the Chief Scientific Officer at Leap Therapeutics, highlighted the pressing need for effective treatment options, as existing therapies have not proven successful.
"Cancer cachexia is a life-affecting condition that severely impacts patients, creating a need for innovative solutions," Dr. Baum commented. "Our studies indicate that FL-501 not only stands out as a potential best-in-class therapy but also shows remarkable results in restoring body composition in preclinical tests, outperforming many clinical-stage therapies. We are enthusiastic about advancing FL-501 into clinical phases as we move towards 2026."
FL-501: Key Findings from Preclinical Studies
The data presented from various studies reveal significant findings that highlight FL-501's efficacy and improved properties:
- In extensive research involving humanized FcRn mouse studies, FL-501 exhibited a remarkable 2-3-fold extended half-life and a 50% reduction in clearance compared to its original precursor and other competing antibodies.
- Utilizing a mouse model of cachexia with GDF-15-overexpressing colorectal cancer cells, FL-501 effectively restored body composition, presenting results commensurate or superior to currently available clinical-stage antibodies.
- In additional trials involving patient-derived xenograft models from non-small cell lung cancer, FL-501 successfully countered cisplatin-induced weight loss, effectively reversing changes in body weight and overall condition.
- These preclinical results amply confirm the role of GDF-15 in cachexia and substantiate the advancement of FL-501 in future development stages.

Exploring the Potential of FL-501
FL-501's design aims for enhanced efficacy in treating conditions characterized by elevated GDF-15 levels. GDF-15 is associated with not only cancer cachexia but also various states of immunosuppression. With carefully engineered properties for higher affinity and longevity, FL-501 signals promise for treating multiple conditions linked to GDF-15, supported by a collaboration with Adimab.
