Cell experiment: | Primary human sebocytes are grown to confluence in 96-well plates in sebocyte growth medium and stimulated with 1 μM human insulin and 1 μM liver X receptor (LXR) agonist T0901317 in the presence of increasing concentrations of TOFA or olumacostat glasaretil in culture medium containing 0.1% DMSO. After 24 hours, stimulation/treatment medium is removed and test articles are reapplied in labeling medium containing [14C]-acetate. Following an additional 16 hours, cells are harvested using trypsin/EDTA. Lipid extracts are prepared and the amount of [14C]-acetate incorporation is determined by liquid scintillation as a measure of de novo fatty acid synthesis[1]. |
Animal experiment: | Hamster: To assess treatment effects on ACC activity, hamsters receive 20 L of solvent mixture with or without 6% olumacostat glasaretil, once daily onto one ear for 1, 4 or 7 days. Punch biopsies are harvested 24 hours after the final dose. Livers are harvested 24 hours after the 7th application. HPLC CoA ester analysis is adapted[1]. |

Olumacostat glasaretil is a small molecule inhibitor of acetyl coenzyme A carboxylase (ACC).
Acetyl coenzyme A carboxylase controls the first, rate limiting step in fatty acid biosynthesis. Olumacostat glasaretil inhibits de novo lipid synthesis in primary and transformed human sebocytes. At 3 μM, olumacostat glasaretil reduces fatty acid synthesis to at or below baseline levels. 14C-acetate incorporation levels are 85%-90% lower forSEB-1 cultures treated with olumacostat glasaretil at 20 μM compared to control samples. At 3 μM, olumacostat glasaretil reduces sebocyte triacylglycerol, cholesteryl/wax ester, diacylglycerol, cholesterol and phospholipid levels from control values on average by approximately 86%, 57%, 51%, 39% and 37%, respectively[1].
Olumacostat glasaretil is a pro-drug of the ACC inhibitor 5-(tetradecyloxy)-2-furoic acid (TOFA) and is designed to enhance delivery in vivo. Topical application of olumacostat glasaretil but not TOFA significantly reduces hamster ear sebaceous gland size. HPLC analyses of hamster ear extracts shows that olumacostat glasaretil treatment increases ACC levels and the ratio of acetyl-CoA to free CoA in tested animals, indicating increased fatty acid oxidation. These changes are consistent with ACC inhibition. Matrix-assisted laser desorption/ionization (MALDI) imaging reveals that OG applied onto Yorkshire pig ears accumulates in sebaceous glands relative to the surrounding dermis[1]. At week 12, OG treatment shows greater reductions from baseline in inflammatory lesions and noninflammatory lesions, and more patients with greater than or equal to 2-grade improvement in investigator global assessment score than vehicle[2].

One of the most common dermatologic concerns is oily skin, and the demand for effective treatment options is ever apparent. This review article addresses numerous topical treatment options such as retinoids, Olumacostat glasaretil, and various cosmeceutical agents. several systemic and procedural techniques that incorporate isotretinoin, spironolactone, oral contraceptives, botulinum toxin, photodynamic therapy, and lasers are reviewed as well. Each treatment option is analyzed in terms of the proposed mechanism of action, efficacy reported in the literature, and potential adverse effects.
Olumacostat glasaretil, a Promising Topical Sebum-Suppressing Agent that Affects All Major Pathogenic Factors of Acne Vulgaris
J Invest Dermatol 2017 Jul;137(7):1405-1408.28647025 10.1016/j.jid.2017.01.026
Hunt et al. show that Olumacostat glasaretil, an inhibitor of acetyl coenzyme A carboxylase, reduces saturated and monounsaturated fatty acyl chains in sebaceous lipids. Topical Olumacostat glasaretil application decreases hamster ear sebaceous gland size and shows efficacy in treating patients with acne vulgaris. Olumacostat glasaretil-mediated sebum suppression may reduce Propionibacterium acnes growth and biofilm formation, comedogenesis, and inflammation.
From pathogenesis of acne vulgaris to anti-acne agents
Arch Dermatol Res 2019 Jul;311(5):337-349.30859308 10.1007/s00403-019-01908-x
Acne vulgaris is a cutaneous chronic inflammatory disorder with complex pathogenesis. Four factors play vital roles in acne pathophysiology: hyperseborrhea and dysseborrhea, altered keratinization of the pilosebaceous duct, Cutibacterium acnes (C. acnes) and inflammation. The main hormones responsible for the development of acne vulgaris include androgens, insulin and insulin-like growth factor-1. Other factors involved in this process are corticotropin-releasing hormone, α-melanocyte-stimulating hormone and substance P. Wnt/β-catenin signaling pathway, phosphoinositide 3-kinase (PI3K)/Akt pathway, mitogen-activated protein kinase pathway, adenosine 5'-monophosphate-activated protein kinase pathway and nuclear factor kappa B pathway participate in the modulation of sebocyte, keratinocyte and inflammatory cell (e.g. lymphocytes, monocytes, macrophages, neutrophils) activity. Among all the triggers and pathways mentioned above, IGF-1-induced PI3K/Akt/Forkhead box protein O1/mammalian target of rapamycin (mTOR) C1 pathway is the most important signaling responsible for acne pathogenesis. Commonly used anti-acne agents include retinoids, benzoyl peroxide, antibiotics and hormonal agents (e.g. spironolactone, combination oral contraceptive and flutamide). New approaches including peroxisome proliferator-activated receptor γ modifier, melanocortin receptor antagonists, epigallocatechin-3-gallate, metformin, Olumacostat glasaretil, stearoyl-CoA desaturase inhibitor omiganan pentahydrochloride, KDPT, afamelanotide, apremilast and biologics have been developed as promising treatments for acne vulgaris. Although these anti-acne agents have various pharmacological effects against the diverse pathogenesis of acne, all of them have a synergistic mode of action, the attenuation of Akt/mTORC1 signaling and enhancement of p53 signal transduction. In addition to drug therapy, diet with no hyperglycemic carbohydrates, no milk and dairy products is also beneficial for treatment of acne.
Olumacostat glasaretil, a novel topical sebum inhibitor, in the treatment of acne vulgaris: A phase IIa, multicenter, randomized, vehicle-controlled study
J Am Acad Dermatol 2017 Jan;76(1):33-39.28029390 10.1016/j.jaad.2016.08.053
Background: Olumacostat glasaretil (OG) inhibits acetyl-coenzyme A carboxylase, the enzyme responsible for the first, rate-limiting step in de novo fatty acid synthesis. OG inhibited in vitro human sebocyte lipid production and reduced in vivo sebaceous gland size in hamster ears. Objectives: Safety and efficacy of OG 7.5% gel were evaluated in patients with moderate to severe facial acne vulgaris. Methods: Patients were randomized (1:1) to twice-daily application of OG or vehicle for 12 weeks. Efficacy was measured through changes in lesion counts and improvement in acne severity scores. Results: A total of 108 patients received OG (n = 53) or vehicle (n = 55); these groups had mean baseline counts of 29.7 and 28.6 inflammatory and 40.9 and 38.8 noninflammatory lesions, respectively. At week 12, OG treatment showed greater reductions from baseline in inflammatory lesions (-63.9% vs -45.9%; P = .0006) and noninflammatory lesions (-48.1% vs -28.8%; P = .0025), and more patients with greater than or equal to 2-grade improvement in investigator global assessment score (24.5% vs 7.3%; P = .0070) than vehicle. Application-site adverse events (typically mild or moderate intensity) were more common with OG. Limitations: Larger trials are needed to optimize OG dosing and confirm the current results. Conclusion: OG was well tolerated and showed evidence of efficacy, suggesting further development is warranted.
Inhibition of Sebum Production with the Acetyl Coenzyme A Carboxylase Inhibitor Olumacostat glasaretil
J Invest Dermatol 2017 Jul;137(7):1415-1423.28259683 10.1016/j.jid.2016.12.031
Olumacostat glasaretil (OG) is a small molecule inhibitor of acetyl coenzyme A (CoA) carboxylase (ACC), the enzyme that controls the first rate-limiting step in fatty acid biosynthesis. Inhibition of ACC activity in the sebaceous glands is designed to substantially affect sebum production, because over 80% of human sebum components contain fatty acids. OG inhibits de novo lipid synthesis in primary and transformed human sebocytes. TrueMass Sebum Panel analyses showed a reduction in saturated and monounsaturated fatty acyl chains across lipid species, including di- and triacylglycerols, phospholipids, cholesteryl esters, and wax esters in OG-treated sebocytes. There was no shift to shorter acyl chain lengths observed, suggesting that the fatty acid chain elongation process was not affected. OG is a pro-drug of the ACC inhibitor 5-(tetradecyloxy)-2-furoic acid and was designed to enhance delivery in vivo. Topical application of OG but not 5-(tetradecyloxy)-2-furoic acid significantly reduced hamster ear sebaceous gland size, indicating that this pro-drug approach was critical to obtain the desired activity in vivo. High-performance liquid chromatography analyses of hamster ear extracts showed that OG treatment increased ACC levels and the ratio of acetyl-CoA to free CoA in these animals, indicating increased fatty acid oxidation. These changes are consistent with ACC inhibition. Matrix-assisted laser desorption/ionization imaging showed that OG applied onto Yorkshire pig ears accumulated in sebaceous glands relative to the surrounding dermis. Sebaceous gland ACC represents an attractive therapeutic target given its central role in formation of sebum, a key factor in acne pathogenesis.
