Aticaprant, also known by its developmental codes JNJ-67953964, CERC-501, and LY-2456302, is a κ-opioid receptor (KOR) antagonist which is under development for the treatment of major depressive disorder.[2][3][4] A regulatory application for approval of the medication is expected to be submitted by 2025.[2] Aticaprant is taken by mouth.[1]
Side effects of aticaprant include itching, among others.[4][5] Aticaprant acts as a selective antagonist of the KOR, the biological target of the endogenous opioid peptide dynorphin.[3] The medication has decent selectivity for the KOR over the μ-opioid receptor (MOR) and other targets, a relatively long half-life of 30 to 40 hours, and readily crosses the blood–brain barrier to produce central effects.[4][6]
Aticaprant was originally developed by Eli Lilly, was under development by Cerecor for a time, and is now under development by Janssen Pharmaceuticals.[2] As of July 2022, it is in phase III clinical trials for major depressive disorder.[2] Like other kappa opioid antagonists currently under clinical investigation for the treatment of major depression, its efficacy may be compromised by the countervailing activation of pro-inflammatory cytokines in microglia within the central nervous system.[7]
Aticaprant was also under development for the treatment of alcoholism, cocaine use disorder, and nicotine withdrawal, but development for these indications was discontinued.[2]
Pharmacology
[edit]Pharmacodynamics
[edit]Aticaprant is a potent, selective, short-acting (i.e., non-"inactivating") antagonist of the KOR (Ki = 0.81 nM vs. 24.0 nM and 155 nM for the μ-opioid receptor (MOR) and δ-opioid receptor (DOR), respectively; approximately 30-fold selectivity for the KOR).[8][9][10] The drug has been found to dose-dependently block fentanyl-induced miosis at 25 mg and 60 mg in humans (with minimal to no blockade at doses of 4 to 10 mg), suggesting that the drug significantly occupies and antagonizes the MOR at a dose of at least 25 mg but not of 10 mg or less.[10] However, a more recent study assessing neuroendocrine effects of the drug in normal volunteers and subjects with a history of cocaine dependence reported observations consistent with modest MOR antagonism at the 10 mg dose.[11] In animal models of depression, aticaprant has been found to have potent synergistic efficacy in combination with other antidepressants such as citalopram and imipramine.[12]
Positron emission tomography imaging revealed that brain KORs were almost completely saturated by the drug 2.5 hours following a single dose of 10 mg, which supported the 4 mg to 25 mg dosages that aticaprant is being explored at in clinical trials.[13][14] Occupancy was 35% for a 0.5 mg dose and 94% for a 10 mg dose.[15][14] At 24 hours post-dose, receptor occupancy was 19% for 0.5 mg and 82% for 25 mg.[15][14] No serious side effects were observed, and all side effects seen were mild to moderate and were not thought to be due to aticaprant.[14]
Pharmacokinetics
[edit]The oral bioavailability of aticaprant is 25%.[1] The drug is rapidly absorbed, with maximal concentrations occurring 1 to 2 hours after administration.[1] It has an elimination half-life of 30 to 40 hours in healthy subjects.[1] The circulating levels of aticaprant increase proportionally with increasing doses.[1] Steady-state concentrations are reached after 6 to 8 days of once-daily dosing.[1] Aticaprant has been shown to reproducibly penetrate the blood–brain barrier.[13][14]
History
[edit]Aticaprant was originally developed by Eli Lilly under the code name LY-2456302.[2] It first appeared in the scientific literature in 2010 or 2011.[16][17] The compound was first patented in 2009.[18]
In February 2015, Cerecor Inc. announced that they had acquired the rights from Eli Lilly to develop and commercialize LY-2456302 (under the new developmental code CERC-501).[19]
As of 2016, aticaprant has reached phase II clinical trials as an augmentation to antidepressant therapy for treatment-resistant depression.[20][12] A phase II study of aticaprant in heavy smokers was commenced in early 2016 and results of the study were expected before the end of 2016.[14] Aticaprant failed to meet its main endpoint for nicotine withdrawal in the study.[21]
In August 2017, it was announced that Cerecor had sold its rights to aticaprant to Janssen Pharmaceuticals.[22][21] Janssen was also experimenting with esketamine for the treatment of depression as of 2017.[21]
Research
[edit]In addition to major depressive disorder, aticaprant was under development for the treatment of alcoholism, cocaine use disorder, and smoking withdrawal.[2] However, development for these indications was discontinued.[2]
