Overview
11 DESCRIPTION DOJOLVI (triheptanoin) is a synthetic medium odd-chain (C7) triglyceride supplied as a colorless to light yellow clear oral liquid. The chemical name of triheptanoin is heptanoic acid, 1,1',1''-(1,2,3-propanetriyl) ester. The empirical formula is C 24 H 44 O 6 and its molecular weight is 428.6 g/mol. The chemical structure is: The caloric value of triheptanoin is 8.3 kcal/mL.
Mechanism of Action
12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Triheptanoin is a medium-chain triglyceride consisting of three odd-chain 7-carbon length fatty acids (heptanoate) that provide a source of calories and fatty acids to bypass the long-chain FAOD enzyme deficiencies for energy production and replacement. 12.2 Pharmacodynamics No formal pharmacodynamic studies have been conducted with DOJOLVI. 12.3 Pharmacokinetics Following oral administration, triheptanoin is extensively hydrolyzed to heptanoate and glycerol by pancreatic lipases in the intestines. The exposure of triheptanoin in the human plasma is minimal. Pharmacokinetics of heptanoate exhibits high inter-patient variability. Heptanoate exposure increases greater than dose-proportional in the dose range between triheptanoin 0.3 and 0.
Indications
- 1 INDICATIONS AND USAGE DOJOLVI is indicated as a source of calories and fatty acids for the treatment of adult and pediatric patients with molecularly confirmed long-chain fatty acid oxidation disorders (LC-FAOD). DOJOLVI is a medium-chain triglyceride indicated as a source of calories and fatty acids for the treatment of adult and pediatric patients with molecularly confirmed long-chain fatty acid oxidation disorders (LC-FAOD).
Common Doses
- 5 mL
- 30 mL
Dosage
2 DOSAGE AND ADMINISTRATION Assess metabolic requirements by determining daily caloric intake (DCI) prior to calculating the dose of DOJOLVI. ( 2.1 ) For patients receiving another medium-chain triglyceride product, discontinue prior to the first dose of DOJOLVI. ( 2.3 ) The recommended target daily dosage of DOJOLVI is up to 35% of the patient's total prescribed DCI divided into at least four doses and mixed thoroughly into semi-solid food/liquid or medical food/formula at mealtimes or with snacks.

Side Effects
- 6 ADVERSE REACTIONS Most common adverse reactions are (≥10%): abdominal pain, diarrhea, vomiting, and nausea. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Ultragenyx Pharmaceutical Inc. at 1-888-756-8657 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trial Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
Interactions
- 7 DRUG INTERACTIONS 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.
