Trifarotene, sold under the brand name Aklief, is a medication for the topical treatment of acne vulgaris in those nine years of age and older.[1] It is a retinoid;[2] more specifically, it is a fourth generation selective retinoic acid receptor (RAR)-γ agonist.[3]

It was approved for medical use in the United States in 2019,[1][4][5] but is not approved in the European Union as of January 2021.[6] Trifarotene was granted orphan drug designation for the treatment of congenital ichthyosis by both the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA).[7][8]

For treatment of congenital ichthyosis, PRECLINICAL, Galderma Res & Dev,

Galderma announced that the U.S. Food and Drug Administration (FDA) granted Orphan Drug Designation status for the company’s trifarotene molecule for the treatment of congenital ichthyosis. Based on this decision, Galderma plans to implement a clinical development plan, reinforcing its commitment to exploring new treatment options for rare diseases, as well as meeting the needs of all patients with skin diseases over the course of their lives.

Chemical structure for Trifarotenetrifarotene

The company’s molecule trifarotene is a selective agonist of the gamma retinoic acid receptor (RAR-gamma), which is currently in clinical development for use in other more common dermatological conditions. It is the drug’s retinoid functionality and potent keratolytic properties that make it a potentially viable treatment of the lamellar ichthyosis pathology. Galderma has already initiated the program for investigating the treatment of lamellar ichthyosis with trifarotene and is currently working in collaboration with regulatory authorities to implement an innovative and expedient clinical development plan.

 

Ichthyoses comprise a large group of skin scaling disorders with diverse etiologies. The stereotypic pathophysiology is epidermal hyperplasia and abnormal desquamation, leading to visible accumulation of squames (scales) on the skin’s surface. Congenital ichthyosis is a term used to refer to a specific group of rare inherited forms of ichthyoses that are generally more severe than non-inherited forms of the disease. Lamellar ichthyosis is one such disorder that falls within the congenital ichthyosis category. Lamellar ichthyosis is recognized as a severe disease which persists throughout life. After birth, during the first post-natal weeks, the hyperkeratotic (colloidion) membrane patients are typically born with, is gradually shed and is replaced by scaling and lichenification that involves the entire body, including face, scalp, palms and soles. While usually not life threatening, lamellar ichthyosis can result in disability, partial deafness, poor adaptation to environmental conditions (due to hypohydrosis), severe discomfort (pruritus, fissuring of the skin), and significant psycho-social impact. The estimated prevalence of LI in the US is in the range of 1 per 100,000 to 1 per 200,000 persons.

New Drug Approvals for 2019: Synthesis and Clinical Applications

Trifarotene (Aklief). In October 2019, trifarotene, a topical retinoid that
selectively targets retinoic acid receptor gamma (RAR-γ), was approved by the FDA
for the treatment of acne vulgaris [142]. The drug was developed and marketed by
Galderma Pharmaceutical in Switzerland. Trifarotene is considered as the first of the
‘fourth-generation’ retinoids due to its uniquely selective agonism at RAR-γ. The
selective agonism leads to downstream alterations, confering improved efficacy and
reduced side effects [143]. In two phase 3 clinical trials of 2420 patients with
moderate acne on the face and trunk, trifarotene was well tolerated and significantly
reduced inflammatory lesions as early as two weeks on the face and four weeks on the
back, shoulders and chest compared to vehicle (p<0.05) [144].
The synthetic approach of this drug was disclosed by Galderma Research &
Development (Scheme 25) [145]. Bromination of commercially available
2-(tert-butyl)aniline 171 gave 4-bromo-2-(tert-butyl)aniline 172 in quantitative yield,
which then reacted with 1-dibromobutane 173 to give phenylpyrrolidine 174 in 52%
yield. Miyaura reaction of 174 was realized by employing n-BuLi and triisopropyl
borate (TIPB) followed by washed with aqueous HCl, resulting in arylboronic acid
adduct 175 in 66% yield. Treatment of 175 with aromatic bromide 176 in the presence
of Pd(PPh3)4 gave the coupling product 177 in 47% yield, which then underwent
hydrolysis delivering trifarotene (XIX) in 55% yield.
The preparation of coupling partner 176 is depicted in Scheme 26. Esterification of
4-hydroxy-4-biphenylcarboxylic acid 178 gave ethyl benzoate derivative 179 upon
treatment with catalytic H2SO4 in the refluxing EtOH [145]. The resulting ester was
subjected to treatment with tetrabutylammonium bromide (TBAB) in THF, resulting
in bromide 180 in good yields, further NaH-mediated Williamson ether synthesis with
2-bromoethyl acetate 181 gave 176 in 95% yield.
