- Phase 2 study demonstrating avexitide significantly reduced hypoglycemia in children with congenital hyperinsulinism published in Diabetes Care
- Eiger plans to initiate avexitide Phase 3 registrational program by year-end 2022
PALO ALTO, Calif., April 25, 2022 /PRNewswire/ -- Eiger BioPharmaceuticals, Inc. (NASDAQ: EIGR), a commercial-stage biopharmaceutical company focused on the development of innovative therapies to treat and cure hepatitis delta virus (HDV) and other serious diseases, today announced the publication of data demonstrating that treatment with avexitide significantly reduced the likelihood of fasting and protein-induced hypoglycemia in patients with congenital hyperinsulinism (HI).
The investigator sponsored study conducted at Children's Hospital of Philadelphia (CHOP) provides further evidence of avexitide's targeted therapeutic approach to treat HI and supports advancing avexitide into Phase 3 development.
"CHOP has been a strong supporter and development partner for avexitide, and we are pleased to see the publication of these positive results," said David Cory, President and CEO, Eiger. "Their early investigation of avexitide in congenital hyperinsulinism generated important foundational proof of concept data in this patient population. Armed with these data, we are moving forward into Phase 3 this year as we believe avexitide has the potential to transform the lives of children with this life-threatening condition."
Eiger has obtained alignment with FDA on the avexitide HI registration program. Avexitide has been granted orphan drug designation in the U.S. by FDA for the treatment of hyperinsulinemic hypoglycemia (which includes HI) and has also been granted rare pediatric disease designation making it eligible for a priority review voucher upon regulatory approval. Avexitide is the only investigational therapy for HI granted breakthrough therapy designation by FDA.
"The impact of this disease on patients and families can be devastating, with newborns often requiring intensive care hospitalization, surgery, and years of intensive management," said senior study author Diva D. De León-Crutchlow, MD, Chief of the Division of Endocrinology and Diabetes and Director of the Congenital Hyperinsulinism Center at Children's Hospital of Philadelphia. "With no approved treatments for HI currently available, new, effective therapies are urgently needed. Eiger's initiation of the avexitide Phase 3 program is therefore an important step for this community."
This open-label, crossover study (N=16) was designed to test the effects of avexitide (referred to as exendin (9-39) in the study) compared to a saline control on fasting- and protein-induced hypoglycemia in children with HI. Compared to control, avexitide treatment resulted in a 76% reduction in the likelihood of fasting hypoglycemia in the mid-dose (0.44 mg/kg) group and an 84% reduction in the likelihood of hypoglycemia in the high dose (0.6 mg/kg) group. Avexitide treatment (0.6 mg/kg) during protein tolerance testing resulted in an 82% reduction in the likelihood of hypoglycemia. The mid-dose group also demonstrated a 20% increase in fasting glucose, while the high dose resulted in a 28% increase in glucose after a meal and a 30% increase in glucose after protein challenge.
Congenital hyperinsulinism (HI), a rare genetic disease, is the most common cause of persistent hypoglycemia (low blood sugar) in infants and children. The estimated incidence of between 1 in 2,500 and 1 in 50,000 live births2-3 results in approximately 80-100 new cases of HI in the U.S. each year, 60% of which are diagnosed within the first month of life. It is characterized by inappropriate and persistent insulin secretion from the beta-cells of the pancreas, and results in permanent brain damage with neurodevelopmental deficits in up to 50% of patients. Near-total pancreatectomy is often indicated and leads to life-long insulin-dependent diabetes (IDDM). There are no approved therapies for HI; safe and effective therapies are urgently needed to prevent brain damage, IDDM, and death.
Avexitide is an investigational, first-in-class glucagon-like peptide-1 receptor (GLP-1r) antagonist in development for the treatment of congenital hyperinsulinism (HI) and post-bariatric hypoglycemia (PBH). Avexitide has been granted breakthrough therapy designation for both HI and PBH.
By binding to the GLP-1r, avexitide inhibits GLP-1r signaling, thereby reducing dysregulated insulin secretion and preventing fasting- and protein-induced hypoglycemia. By addressing underlying disease mechanisms, avexitide may offer the first targeted approach to treatment of hypoglycemia in patients with HI. Eiger has developed a novel formulation of avexitide for subcutaneous injection for its Phase 3 registrational program.
Eiger is a commercial-stage biopharmaceutical company focused on the development of innovative therapies to treat and cure hepatitis delta virus (HDV) and other serious diseases. The Eiger HDV platform includes two first-in-class therapies in Phase 3 that target critical host processes involved in viral replication. Eiger is also developing peginterferon lambda as a therapeutic for COVID-19 and is planning to submit an emergency use authorization application to FDA based on positive results from the investigator sponsored Phase 3 TOGETHER study.
All five Eiger rare disease programs have been granted FDA breakthrough therapy designation: lonafarnib and peginterferon lambda for HDV, Zokinvy for progeria, and avexitide for both HI and PBH.
