Description: Lomitapide is a MTP inhibitor. Lomitapid is a novel agent for the treatment of homozygous familial hypercholesterolemia. Lomitapide is an orally active inhibitor of microsomal triglyceride transfer protein that is indicated as an adjunct to a low-fat diet and other lipid-lowering treatments, including LDL apheresis where available for the reduction of LDL-C, total cholesterol, apolipoprotein B, and non-high-density lipoprotein cholesterol in adult patients with HoFH.

More Info:

Biological target: Lomitapide mesylate(AEGR-733; BMS-201038) is an inhibitor of microsomal triglyceride-transfer protein (MTP) wtih in vitro IC50 of 8 nM.
In vitro activity: Bayesian statistics was previously used as a tool to virtually screen USFDA approved drugs for predicted β-haematin (synthetic haemozoin) inhibition and in vitro antimalarial activity. Here, the experimental evaluation of nine of the highest ranked drugs, is reported, confirming the accuracy of the model by showing an overall 93% hit rate. Lapatinib, nilotinib, and lomitapide showed the best activity for inhibition of β-haematin formation and parasite growth and were found to inhibit haemozoin formation in the parasite, providing mechanistic insights into their mode of antimalarial action. Furthermore, the SBVS method correctly identified the three most important β-haematin inhibiting drugs identified in the USFDA set using the Bayesian model, namely lapatinib, nilotinib, and lomitapide. Lapatinib, nilotinib, and lomitapide were all found to increase the freely exchangeable haem, and decrease haemozoin in a dose dependent manner confirmed by an unpaired two tailed t-test relative to control, therefore confirming that these drugs inhibit cellular haemozoin formation (Figure 2).

In vivo activity: To evaluate whether the new animal model in which ldlr mutant zebrafish are subjected to short-term (5 days) HCD feeding can be useful for drug screening, the effects of probucol, an antioxidant, and lomitapide, an MTP inhibitor, were tested on vascular lipid accumulation. Both probucol and lomitapide have been shown to exert antioxidant and MTP inhibitor properties, respectively, in zebrafish. As was expected, lomitapide decreased the plasma lipid levels in ldlr mutants, as assessed by ORO staining (Fig. 5A), by blocking their absorption in the intestine. Vascular lipid deposits were not decreased by probucol treatment but were significantly decreased by the treatment with lomitapide (Fig. 5B, C), suggesting that lipid levels, but not lipid oxidation, play a dominant role in early vascular lipid accumulation event in loss-of-function ldlr mutant larvae.
