治疗:长链脂肪酸氧化紊乱
Dojolvi(三庚酸甘油酯)是一种中链甘油三酸酯,被指示为卡路里和脂肪酸的来源,用于治疗分子确认的长链脂肪酸氧化紊乱(LC-FAOD)的儿童和成年患者。
2020年6月30日-专注于罕见和超罕见疾病新产品开发和商业化的生物制药公司Ultragenyx Pharmaceutical Inc.今天宣布,美国美国食品药品监督管理局(FDA)已批准Dojolvi™(三庚酸)是卡路里和脂肪酸的来源,用于治疗经分子确认的长链脂肪酸氧化紊乱(LC-FAOD)的儿童和成年患者。LC-FAOD是一类罕见的,终生且威胁生命的遗传疾病,其中人体无法将长链脂肪酸转化为能量。Dojolvi是一种高度纯化的合成7碳脂肪酸甘油三酸酯,专门设计用于提供中链奇碳脂肪酸作为能源,并为LC-FAOD的人们提供代谢物替代品。
“经过今天的FDA批准,患有这种严重,不可预测且经常是灾难性疾病的患者现在已经获得批准的疗法。尽管目前得到了最好的护理,但许多患有长链脂肪酸氧化紊乱的患者仍生活困难,需要经常住院和重大医疗事件。现在,这些患者已获得批准的治疗方法,以帮助控制他们的疾病。” Ultragenyx首席医学官Camille L. Bedrosian,医学博士说。“我们感谢所参与的患者,护理人员,家庭,营养师和医生帮助使这个社区的里程碑成为可能,并且我们致力于确保美国所有可能受益于Dojolvi的LC-FAOD患者都能获得它。”
LC-FAOD是一组常染色体隐性遗传疾病,其特征是代谢缺陷,其中人体无法将长链脂肪酸转化为能量。无法从脂肪中产生能量会导致体内葡萄糖的严重消耗和严重的并发症,从而可能导致住院或早期死亡。由于存在严重后果(包括生命早期死亡)的风险,LC-FAOD被包括在美国和某些欧洲国家的新生儿筛查小组中。当前用于LC-FAOD的其他治疗选择包括避免禁食,低脂/高碳水化合物饮食,肉碱和医用碳素中碳甘油三酸酯(MCT)均匀油。LC-FAOD在美国估计影响2,000至3500名儿童和成人。
“ FDA批准Dojolvi用于治疗长链脂肪酸氧化紊乱对于患者及其家属而言是一个巨大的里程碑,因为它是第一种此类药物,”人类遗传学教授兼医学遗传学负责人Jerry Vockley博士说。 UPMC匹兹堡儿童医院。“虽然我们多年来能够在出生时识别出这些疾病,但治疗选择却受到限制。Dojolvi带来了希望,因为现在可供照顾这些患者的临床医生使用这种新工具。罕见病的研究,尤其是新疗法的研发,是一个艰巨而耗时的过程,今天的公告代表了众多研究人员,临床医生和患者近20年的研究成果。成为这个过程的一部分,我感到非常兴奋。”
Ultragenyx希望Dojolvi在未来30天内可为患者使用。为了支持访问,Ultragenyx的UltraCare®计划可帮助患者和护理人员了解保险范围,并帮助他们找到对Ultragenyx药物(包括Dojolvi)及其管理的财务支持。

FULL PRESCRIBING INFORMATION
1 INDICATIONS AND USAGE
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).
2 DOSAGE AND ADMINISTRATION
2.1 Recommended Dosage
Assess the metabolic requirements of the patient by determining their daily caloric intake (DCI) prior to calculating the dose of DOJOLVI.
For patients receiving another medium-chain triglyceride (MCT) product, discontinue prior to the first dose of DOJOLVI.
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 administered at mealtimes or with snacks.
In order to reach a target daily dosage, patients may require an increase in their total fat intake. All patients treated with DOJOLVI should be under the care of a clinical specialist knowledgeable in appropriate disease-related dietary management based upon current nutritional recommendations.
The neonatal population may require higher fat intake and therefore an increased amount of DOJOLVI. Current nutritional recommendations should be considered when dosing the neonatal population.
The total daily dosage is converted to a volume of DOJOLVI to be administered in mL using the following calculation:
• Caloric value of DOJOLVI = 8.3 kcal/mL
• Round the total daily dosage to the nearest whole number.
• Divide the total daily dosage into at least four approximately equal individual doses.

For patients not currently taking a MCT product
Initiate DOJOLVI at a total daily dosage of approximately 10% DCI divided into at least four times per day and increase to the recommended total daily dosage of up to 35% DCI over a period of 2 to 3 weeks.
2
Confidential
Reference ID: 4633489
For patients switching from another MCT product Discontinue use of MCT products before starting DOJOLVI.
Initiate DOJOLVI at the last tolerated daily dosage of MCT divided into at least four times per day. Increase the total daily dosage by approximately 5% DCI every 2 to 3 days until the target dosage of up to 35% DCI is achieved.
Tolerability
If a patient has difficulty tolerating 1/4 of the total daily dosage at one time, more frequent smaller doses may be considered[see Adverse Reactions (6.1)].
Monitor patients’ total caloric intake during dosage titration, especially in patients with gastrointestinal adverse reactions, and adjust all components of the diet as needed.
If a patient experiences gastrointestinal adverse reaction(s), consider dosage reduction until the gastrointestinal symptoms resolve[see Adverse Reactions (6.1)]. If a patient is unable to achieve the target daily dosage of up to 35% DCI during dosage titration, maintain the patient at the maximum tolerated dosage.
2.3 Preparation and Administration Instructions
Administer DOJOLVI mixed with semi-solid food or liquids orally or enterally via a silicone or polyurethane feeding tube. Do not administer DOJOLVI alone to avoid gastrointestinal upset.
Prepare or administer DOJOLVI using containers, dosing syringes or measuring cups made of compatible materials such as stainless steel, glass, high density polyethylene (HDPE), polypropylene, low density polyethylene, polyurethane and silicone.
DOJOLVI is not compatible with certain plastics. Do not prepare or administer DOJOLVI using containers, dosing 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 into the following semi-solid foods and liquids:
o plain or artificially sweetened fat free yogurt o fat free milk, formula, or cottage cheese
o whole grain hot cereal
o fat free low carbohydrate pudding, smoothies, applesauce, baby food, etc.
• 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 average consumption of the patient in order to ensure administration of the full dose.
• Mix DOJOLVI thoroughly into the food or liquid.
• The mixture may be stored for up to 24 hours in refrigerated conditions.
Feeding Tube Preparation and Administration
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 (5.1)].
Preparation and Administration Instructions
• 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 formula that takes into consideration the age, size and average consumption of the patient in order to ensure administration of the full dose.
• Mix DOJOLVI thoroughly into the formula.
• Draw up the entire amount of the DOJOLVI-formula mixture into a slip tip syringe.
• Remove the residual air from the syringe and connect the syringe directly into the feeding tube feeding port.
• Push the syringe contents into the feeding tube feeding 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 portion of the DOJOLVI-formula mixture. Do not save for later use.
• Administer DOJOLVI over 15 to 20 minutes for patients receiving bolus delivery of enteral feeds. For patients receiving continuous feeds, administer DOJOLVI over 30 to 60 minutes alternating with formula alone.
Missed Doses
If a dose is missed, take the next dose as soon as possible with subsequent doses taken at 3 to 4 hour intervals. Skip the missed dose if it will not be possible to take all four doses in a day.
3 DOSAGE FORMS AND STRENGTHS
Oral liquid: clear, colorless to light yellow liquid supplied in 500 mL bottles containing 100% w/w of triheptanoin.
4 CONTRAINDICATIONS None.
5 WARNINGS AND PRECAUTIONS 5.1 Feeding Tube Dysfunction
Feeding tube performance and functionality can degrade over time depending on usage and environmental conditions. In clinical trials, feeding tube dysfunction was reported in patients receiving triheptanoin. The contribution of DOJOLVI cannot be ruled out. Do not administer DOJOLVI in
4
Confidential
Reference ID: 4633489
feeding tubes manufactured of polyvinyl chloride (PVC)[see Dosage and Administration (2.3)].
Regularly monitor the feeding tube to ensure proper functioning and integrity.
5.2. Intestinal Malabsorption in Patients with Pancreatic Insufficiency
Pancreatic enzymes hydrolyze triheptanoin and release heptanoate as medium-chain fatty acids in the small intestine. Low or absent pancreatic enzymes may result in reduced absorption of heptanoate subsequently leading to insufficient supplementation of medium-chain fatty acids. Avoid administration of DOJOLVI in patients with pancreatic insufficiency.
6 ADVERSE REACTIONS
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.
The safety population included 79 patients with LC-FAOD exposed to DOJOLVI in two studies: one open-label 78-week study of DOJOLVI in 29 patients (Study 1; NCT018863) followed by an open-label extension study (Study 2; NCT022141). Twenty-four patients from Study 1 continued into Study 2. Patients ranged from 4 months to 63 years of age and the population was 52% male. Of the 79 patients, 87% were white, 5% were black or African-American, 4% were Asian and 4% other. The daily dosage of DOJOLVI ranged between 12% and 41% DCI (which corresponds to 0.7 g/kg/day to 6.0 g/kg/day for pediatric patients and 0.5 g/kg/day to 1.3 g/kg/day for adult patients) for a mean duration of 23 months.
The most common adverse reactions to DOJOLVI reported in the pooled safety population of Study 1 and Study 2 were gastrointestinal (GI)-related, and included abdominal pain (abdominal discomfort, abdominal pain, abdominal distension, abdominal pain upper, GI pain) [60%], diarrhea [44%], vomiting [44%], and nausea [14%].
Gastrointestinal (GI) Adverse Reactions
In Study 1 and Study 2, median time to onset of a first occurrence of a GI adverse reaction was 7.3 weeks. GI adverse reactions led to dose reductions in 35% and 12% of patients in Study 1 and Study 2, respectively.
In Study 3 (NCT01379625), a 4-month double-blind randomized controlled study, commonly reported adverse reactions with triheptanoin were similar to those reported in Study 1 and Study 2.
7 DRUG INTERACTIONS
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.
8 USE IN SPECIFIC POPULATIONS 8.1 Pregnancy
5
Confidential
Reference ID: 4633489
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.
Advise women to report pregnancies to Ultragenyx Pharmaceutical Inc. at 1-888-756-8657.
The estimated 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.
8.2 Lactation
Risk Summary
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. Medium-chain triglycerides and other fatty acids are normal components of breastmilk and the composition of breastmilk varies within feedings, over stages of lactation, and between mothers and populations due to maternal factors including genetics, environment, and diet. The developmental and health benefits of breastfeeding
should be considered along with the clinical need for DOJOLVI and any potential adverse effect on the breastfed infant from DOJOLVI or from the underlying condition.
8.4 Pediatric Use
The safety and effectiveness of DOJOLVI have been established in pediatric patients aged birth and older[see Adverse Reactions (6.1), Clinical Studies (14)].

Confidential
Reference ID: 4633489
8.5 Geriatric Use
Clinical studies of DOJOLVI did not include sufficient numbers of patients aged 65 and over to determine whether they respond differently from younger patients.
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 C24H44O6 and its molecular weight is 428.6 g/mol. The chemical structure is:
The caloric value of triheptanoin is 8.3 kcal/mL.
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 0.4 g/kg.
Absorption
The pharmacokinetics of heptanoate in healthy adult subjects following an oral administration of DOJOLVI mixed with food are summarized in Table 1.

The plasma protein binding of heptanoate is approximately 80% and is independent of total concentration.
Elimination
After a single dose of either 0.3 g/kg or 0.4 g/kg triheptanoin to healthy subjects, the mean apparent clearance (CL/F) of heptanoate was 6.05 and 4.31 L/hr/kg, respectively. Half-life (t1/2) of heptanoate could not be determined due to multiple peak concentrations of heptanoate observed.
Metabolism
Heptanoate, formed by hydrolysis of triheptanoin, can be metabolized to beta-hydroxypentanoate (BHP) and beta-hydroxybutyrate (BHB) in the liver.
Excretion
After single or multiple repeat doses of triheptanoin to healthy subjects, triheptanoin and its metabolites were minimally excreted in urine.
Drug Interaction Studies
In Vitro Studies
Heptanoate is not an inhibitor of CYP1A2, CYP2B6, CYP2C8, CYP2C9, CYP2C19, CYP2D6, or
CYP3A4. Heptanoate and BHP are not CYP substrates nor UGT substrates. Heptanoate increases the unbound fraction of valproic acid by approximately 2-fold.
13 NONCLINICAL TOXICOLOGY
13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility
Carcinogenesis
Nonclinical animal studies evaluating long-term administration of triheptanoin have not been conducted to assess the carcinogenic potential of the drug. In a published chronic 9-month dietary study conducted in rats, daily administration of triheptanoin at dose levels up to 1.14 g/kg was associated with atrophy or hyperplasia of the intestinal villa. In a chronic 9-month dietary study

Reference ID: 4633489
conducted in juvenile minipigs, treatment with triheptanoin at dose levels up to 10 g/kg was well tolerated with no changes in histopathology suggestive of any carcinogenic potential.
Published studies with structurally similar triglycerides (i.e. MCTs) were also evaluated. In a 2-year
dietary study of rats fed tricaprylin (C8 MCT) at dose levels up to 9.5 g/kg (approximately 1.2 times the anticipated maximum clinical dose), there were increased incidences of pancreatic and forestomach hyperplasia and adenomas but not carcinomas. Chronic administration of a diet containing approximately 17% MCT was not shown to promote effects on colon tumor incidence in an
azomethane-induced colon tumorigenicity rat model.
Mutagenesis
Triheptanoin was not genotoxic in a battery of genotoxicity tests including the in vitro bacterial reverse mutation inS. typhimurium andE. coli, in vitro mammalian chromosomal aberration test in human peripheral blood lymphocytes and the in vivo mammalian erythrocyte micronucleus test in rat bone marrow.
Impairment of Fertility
Triheptanoin had no effect on fertility or any other parameters of mating performance in rats exposed to repeat dietary administration at dose levels equivalent to up to 50% daily caloric intake (16 g/kg) that resulted in systemic drug exposure (AUC) of heptanoate approximately equal to the maximum recommended human dose.
14 CLINICAL STUDIES
The efficacy of triheptanoin as a source of calories and fatty acids was evaluated in Study 3, a 4 month double-blind randomized controlled study comparing triheptanoin (7-carbon chain fatty acid) with trioctanoin (8-carbon chain fatty acid). The study enrolled 32 adult and pediatric patients with a confirmed diagnosis of LC-FAOD and evidence of at least one significant episode of rhabdomyolysis and at least two of the following diagnostic criteria: disease specific elevation of acylcarnitines on a new born blood spot or in plasma, low enzyme activity in cultured fibroblasts, or one or more known pathogenic mutations inCPT2, ACADVL, HADHA, orHADHB.
The dosage of study drug was titrated to a protocol-specified target of 20% DCI (actual mean daily dose achieved was 16% for triheptanoin and 14% for trioctanoin). The recommended target dosage of DOJOLVI is up to 35% of DCI[see Dosage and Administration (2.1)]. Patients ranged in age from 7 years to 64 years (median 24 years) and 12 were male.
Baseline cardiovascular function in both groups was normal and within test/retest variability normally observed in repeated echocardiograms. After 4 months, patients in both groups had similar mean changes from baseline in left ventricular ejection fraction and wall mass on resting echocardiogram and similar maximal heart rates on treadmill ergometry.
Five patients experienced 7 events of rhabdomyolysis in the triheptanoin group and 4 patients experienced 7 events of rhabdomyolysis in the trioctanoin group.
No differences were observed between triheptanoin and trioctanoin groups in blood markers of metabolism including glucose, insulin, lactate, total serum, ketones, acylcarnitines, and serum-free fatty acid concentrations.
