Bristol-Myers Squibb developed Rimegepant, also known as BMS-927711. Rimegepant is a potent, selective, competitive and orally active calcitonin gene-related peptide (CGRP) antagonist in clinical trials for treating migraine. Rimegepant has shown in vivo efficacy without vasoconstrictor effect; it is superior to placebo at several different doses (75 mg, 150 mg, and 300 mg) and has an excellent tolerability profile.

ADX-N05, originally discovered by SK Holdings, is a selective dopamine and norepinephrine reuptake inhibitor (DNRI). ADX-N05 (Solriamfetol, sold under the brand name Sunosi) is approved in the US and is under regulatory review in the EU to improve wakefulness in adult patients with hypersomnia associated with narcolepsy or obstructive sleep apnoea.The US FDA has approved solriamfetol (Sunosi, Jazz Pharmaceuticals) for the treatment of excessive daytime sleepiness in adults with narcolepsy or obstructive sleep apnea.The dual-acting dopamine and norepinephrine reuptake inhibitor is approved for narcolepsy in once-daily 75 mg and 150 mg doses, and in obstructive sleep apnea in once-daily 37.5 mg, 75 mg, and 150 mg doses.

Siponimod (BAF312) is a dual agonist at the sphingosine-1 phosphate receptors, S1PR1 and S1PR5. The S1P receptor is commonly found on the surface of specific cells residing in the central nervous system (CNS), that are responsible for causing CNS damage that drives loss of function in secondary progressive multiple sclerosis (SPMS). Siponimod (BAF312) enters the brain and by binding to these specific receptors, may prevent the activation of these harmful cells, helping to reduce the loss of physical and cognitive function associated with SPMS.

Upadacitinib (ABT-494) is a Janus kinase 1 (JAK1) inhibitor currently being developed by AbbVie for the treatment of rheumatoid arthritis (RA), Crohn’s disease, ulcerative colitis, atopic dermatitis, and psoriatic arthritis. It is also being investigated as a potential treatment for people with active ankylosing spondylitis (AS). Currently, upadacitinib is being evaluatedin six global phase III studies in RA and twophase III studies in psoriatic arthritis (PsA), inaddition to phase II studies in Crohn’s disease and atopicdermatitis and a combined phase II/III study inulcerative colitis. Upadacitinib is a potent and selective Janus kinase (JAK) 1 inhibitor with an IC50 of 43 nM.

Ubrogepant, a small molecule drug, is being developed by Merck & Co for the treatment of migraine. The calcitonin gene-related peptide receptor (CGRP) antagonist is administered orally as a film coated tablet. Ubrogepant is a competitive antagonist with high affinity, potency, and selectivity for the human CGRP receptor. In the four clinical studies (ACHIEVE I, ACHIEVE II, UBR-MD-04 and 3110-105-002) ubrogepant demonstrated efficacy, safety and tolerability in the acute treatment of migraine among a broad patient population, including those who had an insufficient response to a triptan or those patients in whom triptans were contraindicated, as well as in patients who had moderate to severe CV risk profile.

Fedratinib (SAR-302503, TG-101348) is a selective small-molecule inhibitor of Janus kinase-2. Fedratinib demonstrated therapeutic efficacy in a murine model of myeloproliferative disease. Sanofi was developing Fedratinib for the treatment of myeloproliferative diseases and solid tumors. The clinical development of fedratinib was terminated after reports of Wernicke's encephalopathy in myelofibrosis patients.

Lumateperone (ITI-722/ITI-007) is a dual 5HT2A receptor antagonist/dopamine phosphoprotein modulator (DPPM) for the treatment of schizophrenia. It is an orally available compound which combines potent 5HT2A receptor antagonism with cell-type-specific modulation of phosphoprotein pathways downstream of dopamine receptors. Lumateperone was developed by Intra-Cellular Therapies, Inc., and is being evaluated for the treatment of schizophrenia and bipolar depression. In 3 efficacy studies in patients with acute schizophrenia, lumateperone was well-tolerated with a favorable safety profile, and in 2 studies of 3 demonstrated significantly superior efficacy over placebo.

Pitolisant (INN) or tiprolisant (USAN) is a histamine receptor inverse agonist/antagonist selective for the H3 subtype. It has stimulant and nootropic effects in animal studies and may have several medical applications, having been researched for the treatment of narcolepsy, for which it has been granted orphan drug status in the EU and US. It is currently in clinical trials for schizophrenia and Parkinson’s disease. Pitolisant hydrochloride was approved by European Medicine Agency (EMA) on Mar 31, 2016. It was developed and marketed as Wakix® by Bioprojet in EU. Wakix® is available as the tablet for oral use, containing 4.5 mg and 18 mg of Pitolisant hydrochloride. The initial dose of 9 mg (two 4.5 mg, tablets) per day, and it should be used at the lowest effective dose, depending on individual patient response and tolerance, according to an up-titration scheme, without exceeding the dose of 36 mg/day. Pitolisant was the first clinically used H3 receptor inverse agonist.
