Lomitapide is mainly metabolized by CYP3A4 to it's inactive metabolites, M1 and M3. CYP enzymes that metabolize lomitapide to a minor extent include CYP 1A2,2B6,2C8,2C19.
Lomitapide is metabolized extensively by the liver. The metabolic pathways include oxidation, oxidative N-dealkylation, glucuronide conjugation, and piperidine ring opening. Cytochrome P450 (CYP) 3A4 metabolizes lomitapide to its major metabolites, M1 and M3, as detected in plasma. The oxidative N-dealkylation pathway breaks the lomitapide molecule into M1 and M3. M1 is the moiety that retains the piperidine ring, whereas M3 retains the rest of the lomitapide molecule in vitro. CYPs 1A2, 2B6, 2C8, and 2C19 may metabolize lomitapide to a small extent to M1. M1 and M3 do not inhibit activity of microsomal triglyceride transfer protein in vitro.
IDENTIFICATION AND USE: Lomitapide is a white to off-white powder. Lomitapide is indicated as an adjunct to a low-fat diet and other lipid-lowering treatments, including LDL apheresis where available, to reduce low-density lipoprotein cholesterol (LDL-C), total cholesterol (TC), apolipoprotein B (apo B), and non-high-density lipoprotein cholesterol (non-HDL-C) in patients with homozygous familial hypercholesterolemia (HoFH). HUMAN EXPOSURE AND TOXICITY: Very few data are available on the effects of overdose to lomitapide. The maximum dose administered to human subjects in clinical studies was 200 mg lomitapide, as a single dose, without adverse consequences. Lomitapide should not be used during pregnancy because lomitapide may cause fetal harm when administered to a pregnant woman. Lomitapide may also cause diarrhea and malabsorption in patients with rare hereditary disorders, including galactose intolerance, the Lapp lactase deficiency, and glucose-galactose malabsorption; therefore, use of lomitapide should be avoided in such patients. Lomitapide causes a risk of hepatotoxicity. Lomitapide can cause elevations in transaminases and hepatic steatosis. To what extent lomitapide-associated hepatic steatosis promotes the elevations in transaminases is unknown. Although cases of hepatic dysfunction or hepatic failure have not been reported, there is concern that lomitapide could induce steatohepatitis, which can progress to cirrhosis over several years. Therefore, it should not be administered to patients with moderate or severe hepatic impairment (Child-Pugh class B or C) or patients with active liver disease, including unexplained, persistent elevations in serum aminotransferase concentrations. Lomitapide did not exhibit genotoxic potential in a battery of studies, including an in vitro cytogenetics assay using primary human lymphocytes. ANIMAL STUDIES: In a 2-year dietary carcinogenicity study in mice, lomitapide was administered at doses of 0.3, 1.5, 7.5, 15, or 45 mg/kg/day. There were statistically significant increases in the incidences of liver adenomas and carcinomas in males at doses as low as 1.5 mg/kg/day and in females at as low as 7.5 mg/kg/day. Incidences of small intestinal carcinomas in males and combined adenomas and carcinomas in females were significantly increased at doses as low as 15 mg/kg/day. In 2 year studies in rats, there were no statistically significant drug-related increases in tumor incidences. Reproduction studies were conducted in rats, rabbits and ferrets. Oral gavage doses of 0.04, 0.4, or 4 mg/kg/day lomitapide given to pregnant rats from gestation day 6 through organogenesis were associated with fetal malformations at greater than or equal to 2-times human exposure at the maximum recommended human dose (MRHD) (60 mg) based on plasma AUC comparisons. Fetal malformations included umbilical hernia, gastroschisis, imperforate anus, alterations in heart shape and size, limb malrotations, skeletal malformations of the tail, and delayed ossification of cranial, vertebral and pelvic bones. Oral gavage doses of 1.6, 4, 10, or 25 mg/kg/day lomitapide given to pregnant ferrets from gestation day 12 through organogenesis were associated with both maternal toxicity and fetal malformations at exposures that ranged from less than the human exposure at the MRHD to 5-times the human exposure at the MRHD. Fetal malformations included umbilical hernia, medially rotated or short limbs, absent or fused digits on paws, cleft palate, open eye lids, low-set ears, and kinked tail. In rabbits, exposures up to 3 times the MRHD based on body surface area (BSA) (MRDH-BSA) from gestational day 6 through organogenesis were not associated with adverse effects. However, exposure equal to or greater than 6 times the MRHD-BSA resulted in embryo-fetal death. Lomitapide had no effect on fertility in rats at doses up to 5 mg/kg/day at systemic exposures estimated to be 4-times (females) and 5-times (males) higher than in humans at 60 mg based on AUC. Lomitapide did not exhibit genotoxic potential in a battery of studies, including the in vitro Bacterial Reverse Mutation (Ames) and an oral micronucleus study in rats.
Lomitapide is associated with a moderately high rate of serum aminotransferase elevations during therapy, levels above 3 times the upper limit of normal (ULN) occurring in 34% of patients. Aminotransferase elevations above 10 times ULN have also been reported which can necessitate drug discontinuation. Despite the frequency of ALT elevations, however, increases in serum bilirubin and alkaline phosphatase levels are rare and there have been no reports of clinically apparent acute liver injury with jaundice. Chronic therapy with lomitapide can be associated with fluctuations in serum aminotransferase levels and accumulation of liver fat. In some instances, the increase in liver fat is from baseline levels of
◉ Summary of Use during Lactation:No relevant published information exists with the use of lomitapide during breastfeeding. Because of a concern with disruption of infant lipid metabolism and possible tumorigenicity, lomitapide should not be used during breastfeeding.
◉ Effects in Breastfed Infants:Relevant published information was not found as of the revision date.
◉ Effects on Lactation and Breastmilk:Relevant published information was not found as of the revision date.
Concomitant use of lomitapide with potent (e.g., boceprevir, clarithromycin, conivaptan, indinavir, itraconazole, ketoconazole, lopinavir/ritonavir, nefazodone, nelfinavir, posaconazole, ritonavir, saquinavir, telaprevir, telithromycin, tipranavir/ritonavir, voriconazole) or moderate CYP3A4 inhibitors (e.g., aprepitant, atazanavir, ciprofloxacin, crizotinib, darunavir/ritonavir, diltiazem, erythromycin, fluconazole, fosamprenavir, imatinib, verapamil) is contraindicated. If concomitant use with moderate or potent CYP3A4 inhibitors cannot be avoided, lomitapide therapy should be interrupted during the course of treatment with the CYP3A4 inhibitor.
Concomitant use of lomitapide with inhibitors of CYP3A4 may result in increased systemic exposure to lomitapide. When the potent CYP3A4 inhibitor ketoconazole (200 mg twice daily for 9 days) was administered concomitantly with lomitapide (60 mg once daily), peak plasma concentration and area under the plasma concentration-time curve (AUC) of lomitapide were increased by 15- and 27-fold, respectively. When the potent CYP3A4 inhibitor clarithromycin was added to lomitapide therapy in at least 1 patient, ALT and AST concentrations were increased to 24 and 13 times the upper limit of normal (ULN), respectively, within days of initiating the potent CYP3A4 inhibitor. Concomitant use of lomitapide with moderate inhibitors of CYP3A4 has not been studied; however, results of pharmacokinetic studies evaluating concomitant use of lomitapide with potent and weak CYP3A4 inhibitors suggest that moderate CYP3A4 inhibitors will likely increase lomitapide exposure.
