Preparation and administration
Preparation and Administration Instructions Administer DOJOLVI by mixing thoroughly with semi-solid food/liquid (oral administration) or medical food/formula (feeding tube administration). Do not administer DOJOLVI alone to avoid gastrointestinal upset and feeding tube degradation [see Adverse Reactions ] . Prepare or administer DOJOLVI using containers, oral syringes, or measuring cups made of compatible materials such as stainless steel, glass, high density polyethylene (HDPE), polypropylene, low density polyethylene, polyurethane, and silicone.
Do not prepare or administer DOJOLVI using containers, oral syringes, or measuring cups made of polystyrene or polyvinyl chloride (PVC) plastics. Regularly monitor the containers, dosing components, or utensils that are in contact with DOJOLVI to ensure proper functioning and integrity. Oral Preparation and Administration Use an oral syringe or measuring cup made of compatible materials as listed above to withdraw the prescribed volume of DOJOLVI from the bottle.
DOJOLVI can be mixed with soft food or liquid such as: plain or artificially sweetened fat free yogurt fat free milk, formula, or cottage cheese whole grain hot cereal fat free low carbohydrate pudding, smoothies, applesauce, or baby food Add the prescribed amount of DOJOLVI to a clean bowl, cup, or container, made of the compatible materials as listed above, which contains an appropriate amount of semi-solid food or liquid that takes into consideration the age, size, and fluid needs of the patient to ensure administration of the full dose.
Mix DOJOLVI thoroughly into the food or liquid. Any unused mixture may be stored for up to 24 hours in refrigerated conditions. If not used within 24 hours, discard DOJOLVI mixture in the trash. Do not pour down the sink. Do not save for later . Feeding Tube Preparation and Administration DOJOLVI is administered as an oral or enteral bolus medication.
Do not add DOJOLVI to the feeding bag, as the feeding equipment may degrade over time. DOJOLVI can be administered via oral or enteral feeding tubes manufactured of silicone or polyurethane. Do not use feeding tubes manufactured of polyvinyl chloride (PVC). Feeding device performance and functionality can degrade over time depending on usage and environmental conditions.
Regularly monitor the feeding tube to ensure proper functioning and integrity [see Warnings and Precautions ] . Use an oral syringe or measuring cup made of compatible materials as listed above to withdraw the prescribed volume of DOJOLVI from the bottle. Add the prescribed amount of DOJOLVI to a clean bowl, cup, or container, made of compatible materials as listed above, which contains an amount of medical food or formula that takes into consideration the age, size, and fluid needs of the patient in order to ensure administration of the full dose.
Mix DOJOLVI thoroughly into the medical food or formula prior to administering via feeding tube, y-connector, or feeding tube extension set made of silicone or polyurethane. Draw up the entire amount of the DOJOLVI mixture into a slip tip syringe. Remove the residual air from the syringe and connect the syringe directly into the feeding tube port.
Push the syringe contents into the feeding tube port using steady pressure until empty. Flush the feeding tubes with between 5 mL to 30 mL of water. Flush volume should be modified based on specific patient needs and in cases of fluid restriction. Discard any unused DOJOLVI mixture in the trash. Do not pour down the sink.
Do not save for later use.
Drug interactions
Check triheptanoin against a medication listLabel text (2 paragraphs)
Pancreatic Lipase Inhibitors : Avoid co-administration due to potential for reduced clinical effect of DOJOLVI. ( 7.1 )
7.1 Pancreatic Lipase Inhibitors Co-administration of triheptanoin with a pancreatic lipase inhibitor (e.g., orlistat) may reduce exposure to the triheptanoin metabolite, heptanoate, and reduce the clinical effect of triheptanoin [see Clinical Pharmacology (12.3) ] . Avoid co-administration of DOJOLVI with pancreatic lipase inhibitors.
Contraindications
None. None.
Safety data
Reported adverse events (FAERS)
Liver injury (LiverTox)
ELikelihood score E: Unlikely cause of clinically apparent liver injury.
Triheptanoin is synthetic, medium-chain triglyceride that was developed for nutritional support of patients with long-chain fatty acid oxidation disorders. Triheptanoin is given orally by feeding tube titrated to provide approximately 30% of calories. Triheptanoin therapy has not been associated with elevations in serum aminotransferase or bilirubin levels or to instances of clinically apparent liver injury.
ABCDEA: well known cause; E: unlikely cause. [HD]: high doses only.
Pregnancy and lactation
Pregnancy
8.1 Pregnancy Risk Summary 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. In animal reproduction studies conducted in pregnant rats and rabbits administered triheptanoin during the period of organogenesis, the primary toxicological effect (reduced body weight gain) was considered to be specific to decreased food consumption related to taste aversion in animals, and therefore is not relevant to clinical use in the intended populations. There is a pregnancy safety study for DOJOLVI.
If a patient becomes pregnant while receiving DOJOLVI, healthcare providers should report DOJOLVI exposure by calling Ultragenyx Pharmaceutical Inc. at 1-888-756-8657. The background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively.
Data Animal Data Embryofetal developmental studies have been conducted with triheptanoin in rats and rabbits following oral administration of 10% (3.2 g/kg), 30% (9.7 g/kg) and 50% (16 g/kg) DCI in rats and 10% (1.2 g/kg), 20% (2.3 g/kg) and 30% (3.5 g/kg) DCI in rabbits during the period of organogenesis. Reduced body weight gain, associated with decreased food consumption, was observed in pregnant rats and rabbits following administration of triheptanoin food mixture and was attributed to taste aversion. The NOAEL for this maternal toxicity (lack of body weight gain) was 10% DCI for both rats and rabbits.
Administration of dietary triheptanoin to pregnant rats at doses approximately 2 times above, and pregnant rabbits approximately equal to the targeted clinical dose of 35% DCI resulted in increased incidence of skeletal malformations and decreased litter weights in both species and reduced number of viable litters in rabbits. The adverse effects on rat and rabbit embryofetal development were associated with the reduced body weight gain observed in pregnant animals. The NOAEL for embryofetal development toxicity was 30% and 20% DCI for rats and rabbits, respectively.
In a pre- and postnatal developmental study in rats, reduced birthweights and delayed sexual maturation in pups were observed at 50% DCI and were considered secondary to the reductions in body weight gain in pregnant rats.
