Ultragenyx Announces U.S. FDA Approval of Dojolvi™ (UX007/triheptanoin), the First FDA-Approved Therapy for the Treatment of Long-chain Fatty Acid Oxidation Disorders

/EIN News/ -- Fourth U.S. FDA Approval for Ultragenyx in the Past Three Years All for Rare Diseases which Previously Had No Approved Therapies

Ultragenyx to Host Conference Call Today at 4:00 pm Eastern Time

NOVATO, Calif., June 30, 2020 (GLOBE NEWSWIRE) -- Ultragenyx Pharmaceutical Inc. (NASDAQ: RARE), a biopharmaceutical company focused on the development and commercialization of novel products for rare and ultra-rare diseases, today announced that the U.S. Food and Drug Administration (FDA) has approved Dojolvi™ (triheptanoin) as a source of calories and fatty acids for the treatment of pediatric and adult patients with molecularly confirmed long-chain fatty acid oxidation disorders (LC-FAOD). LC-FAOD are a group of rare, lifelong and life-threatening genetic disorders in which the body is unable to convert long-chain fatty acids into energy. Dojolvi is a highly purified, synthetic, 7-carbon fatty acid triglyceride specifically designed to provide medium-chain, odd-carbon fatty acids as an energy source and metabolite replacement for people with LC-FAOD.

“With today’s FDA approval, patients living with this serious, unpredictable, and often catastrophic disease now have an approved therapy. Many patients with long-chain fatty acid oxidation disorders have difficult lives with frequent hospitalizations and major medical events despite the best current care. Now these patients have an approved treatment as an option to help manage their disease,” said Camille L. Bedrosian, M.D., Chief Medical Officer of Ultragenyx. “We are grateful to the patients, caregivers, families, dietitians and doctors involved for helping to make this community milestone possible, and we are committed to ensuring that all patients in the U.S. with LC-FAOD who might benefit from Dojolvi will have access to it.”

LC-FAOD are a group of autosomal recessive genetic disorders characterized by metabolic deficiencies in which the body is unable to convert long-chain fatty acids into energy. The inability to produce energy from fat can lead to severe depletion of glucose in the body and serious complications, which can lead to hospitalizations or early death. LC-FAOD are included in newborn screening panels across the U.S. and in certain European countries due to the risk for serious outcomes including death early in life.  Other current treatment options for LC-FAOD include avoidance of fasting, low-fat/high-carbohydrate diets, carnitine and even-carbon medium-chain triglyceride (MCT) oil, a medical food product. LC-FAOD affect an estimated 2,000 to 3,500 children and adults in the United States.

“FDA approval of Dojolvi for the treatment of long-chain fatty acid oxidation disorders is a huge milestone for patients and their families, as it is the first such medication,” said Dr. Jerry Vockley, Professor of Human Genetics and Chief of Medical Genetics at Children's Hospital of Pittsburgh of UPMC. “While we have been able to identify these disorders at birth for many years, treatment options have been limited. Dojolvi brings hope as a new tool now available to clinicians taking care of these patients. Rare disease research, especially development of new therapies, is an arduous and time consuming process, and today’s announcement represents the culmination of nearly 20 years of work on the part of numerous researchers, clinicians, and patients. I’m tremendously excited to have been a part of this process.”

Ultragenyx expects Dojolvi to be available to patients in the next 30 days. To support access, Ultragenyx’s UltraCare® program helps patients and caregivers understand insurance coverage and assists them in finding financial support for Ultragenyx medicines, including Dojolvi, and for the administration of them. Dedicated in-house UltraCare Guides are available Monday through Friday from 9 a.m. to 8 p.m. Eastern Time at 888-756-8657.

About Dojolvi
Dojolvi is a highly purified, pharmaceutical-grade, odd-carbon medium-chain triglyceride consisting of three 7-carbon fatty acids on a glycerol backbone created via a multi-step chemical process. It is designed to provide medium-chain, odd-carbon fatty acids as an energy source and metabolite replacement for people with LC-FAOD.

Ultragenyx licensed exclusive worldwide rights to triheptanoin from Baylor Research Institute in 2013.

INDICATION
Dojolvi is indicated as a source of calories and fatty acids for the treatment of pediatric and adult patients with molecularly confirmed long-chain fatty acid oxidation disorders (LC-FAOD).

IMPORTANT SAFETY INFORMATION
WARNINGS AND PRECAUTIONS
Feeding Tube Dysfunction

  • Feeding tube dysfunction was reported in patients receiving triheptanoin. The contribution of Dojolvi cannot be ruled out. Dojolvi should not be administered in feeding tubes manufactured of polyvinyl chloride (PVC). The feeding tube should be monitored regularly to ensure proper functioning and integrity.

Intestinal Malabsorption in Patients with Pancreatic Insufficiency

  • Low or absent pancreatic enzymes may result in reduced absorption of heptanoate subsequently leading to insufficient supplementation of medium-chain fatty acids. Administration of Dojolvi should be avoided in patients with pancreatic insufficiency.

ADVERSE REACTIONS
Gastrointestinal (GI)

  • The most common GI-related adverse reactions reported in the pooled safety population of Studies 1 and 2 were abdominal pain (abdominal discomfort, abdominal pain, abdominal distension, abdominal pain upper, GI pain) [60%], diarrhea [44%], vomiting [44%], and nausea [14%].

DRUG INTERACTIONS
Pancreatic Lipase Inhibitors

  • Co-administration should be avoided due to potential for reduced clinical effect of Dojolvi.

USE IN SPECIFIC POPULATIONS
Pregnancy and Lactation

  • There are no available data on triheptanoin use in pregnant women to evaluate for a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. Women are advised to report pregnancies to Ultragenyx Pharmaceutical Inc. at 1-888-756-8657. 
  • There are no data on the presence of triheptanoin or its metabolites in human or animal milk, the effects on the breastfed infant, or the effects on milk production.

PATIENT COUNSELING INFORMATION
The patient or caregiver should: 

  • Read the FDA-approved patient labeling, which includes information on the appropriate oral or feeding tube preparation, administration, and storage.
  • Regularly inspect the feeding tube for proper functioning and integrity and report to the healthcare provider if any issues are identified.
  • Be informed that pancreatic insufficiency may reduce the clinical effect of Dojolvi and to report any known pancreatic insufficiency to the healthcare provider.

You may report side effects to Ultragenyx Pharmaceutical Inc. at 1-888-756-8657 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.
