ODM-201 (also known as BAY-1841788) is a non-steroidal antiandrogen, specifically, a full and high-affinity antagonist of the androgen receptor (AR), that is under development by Orion and Bayer HealthCare for the treatment of advanced, castration-resistant prostate cancer (CRPC). ODM-201 appears to negligibly cross the blood-brain-barrier. This is beneficial due to the reduced risk of seizures and other central side effects from off-target GABAA receptor inhibition that tends to occur in non-steroidal antiandrogens that are structurally similar to enzalutamide. Moreover, in accordance with its lack of central penetration, ODM-201 does not seem to increase testosterone levels in mice or humans, unlike other non-steroidal antiandrogens. Another advantage is that ODM-201 has been found to block the activity of all tested/well-known mutant ARs in prostate cancer, including the recently-identified clinically-relevant F876L mutation. ODM-201 has been studied in phase I and phase II clinical trials and has thus far been found to be effective and well-tolerated, with the most commonly reported side effects including fatigue, nausea, and diarrhea. No seizures have been observed.
Bremelanotide (formerly PT-141) was developed for the treatment of female sexual dysfunction, hemorrhagic shock, and reperfusion injury. Bremelanotide, a synthetic peptide analog of α-melanocyte-stimulating hormone (α-MSH) is an agonist at melanocortin receptors including the MC3R and MC4R, which are expressed primarily in the central nervous system. Bremelanotide originally was tested for intranasal administration in treating female sexual dysfunction but this application was temporarily discontinued in 2008 after concerns were raised over adverse side effects of increased blood pressure. It appears that development for hemorrhagic shock and reperfusion injury has been discontinued. Palatin Technologies licensed North American development and commercialization rights of bremelanotide to Amag in January 2017. In June 2018, the US Food and Drug Administration (FDA) accepted AMAG Pharmaceuticals’ new drug application for bremelanotide for treatment of hypoactive sexual desire disorder in premenopausal women. If approved, bremelanotide will be available as a self-administered, disposable subcutaneous auto-injector used in anticipation of a sexual encounter.
BGB-3111 is a potent and highly selective small molecule BTK inhibitor (Bruton’s Tyrosine Kinase), which we are developing as a monotherapy and in combination with other therapies for the treatment of a variety of lymphomas—the most common form of blood cancer. BGB-3111 blocks the signaling that leads to growth inhibition and cell death in malignant B-cells. In preclinical studies, BGB-3111 showed more restricted off-target activities against a panel of kinases, including ITK. Due to the weaker activity on ITK, BGB-3111 was at least 10 times weaker than ibrutinib in inhibiting rituximab-induced ADCC activity. Both in the REC-1 MCL and ABC subtype DLBCL (TMD-8) xenograft models, BGB-3111 induced dose-dependent antitumor effects and demonstrated superior efficacy in comparison with ibrutinib. Toxicity study in rats indicated that BGB-3111 was very well tolerated, and the MTD was not reached when it was dosed up to 250 mg/ kg/day. The first-in-human, open-label phase 1 trial of BGB-3111 is ongoing as a modified 3 + 3 dose-escalation design (40, 80, 160, 320 mg PO QD; 160 mg PO BID) in patients with advanced B cell malignancies.

GBT440 (previously GTx011) is a potent and direct drug for sickle cell treatment. In sickle cell anemia, abnormal hemoglobin molecules are formed, which causes problems for the flow of blood and oxygen through the body. GBT440 can selectively bind to hemoglobin, thereby increasing its affinity for oxygen. By inhibiting hemoglobin polymerization, it also prevents deformation of the red blood cells. GBT440, renamed Voxelotor, is thought to help prevent sickle cells blocking blood vessels, and therefore reduces pain (sickle cell crisis) experienced by patients. GBT440 is well absorbed following intravenous and oral administration, and quickly partitions into the red blood cell with a small part re‐distributed into the plasma. GBT440 was well tolerated in a randomized, placebo‐controlled, double blind, parallel group phase I/II study in healthy volunteers and sickle cell disease patients. Headache is the most reported adverse event related to the use of this drug, and no serious adverse events are known. A phase 3 clinical trial examining the efficacy and safety of the drug (compared to placebo) is planned to be completed in 2019. Voxelotor was also studied as a potential therapy for treatment of low oxygen levels in the blood of idiopathic pulmonary fibrosis patients, but this program was discontinued because of a lack of clinical benefits.

LASMIDITAN is a serotonin (5-HT) receptor agonist without vasoconstrictor activity, which selectively binds to the 5-HT(1F) receptor subtype. It is under development for the treatment of migraine.

LEFAMULIN is a pleuromutilin antibiotic under development for the treatment of community-acquired bacterial pneumonia, as well as acute bacterial skin and skin structure infections. It inhibits bacterial protein synthesis by binding to the peptidyl transferase center of the 50S ribosome, resulting in the cessation of bacterial growth.
Pexidartinib (PLX3397) is a small-molecule receptor tyrosine kinase (RTK) inhibitor with potential antineoplastic activity. Pexidartinib binds to and inhibits phosphorylation of stem cell factor receptor (KIT), colony-stimulating factor-1 receptor (CSF1R) and FMS-like tyrosine kinase 3 (FLT3), which may result in the inhibition of tumor cell proliferation and down-modulation of macrophages, osteoclasts and mast cells involved in the osteolytic metastatic disease. FDA has granted Breakthrough Therapy Designation to pexidartinib (PLX3397) for the treatment of tenosynovial giant cell tumor (TGCT) where surgical removal of the tumor would be associated with potentially worsening functional limitation or severe morbidity. In addition to Breakthrough Therapy Designation, pexidartinib (PLX3397) has been granted Orphan Drug Designation by FDA for the treatment of pigmented villonodular synovitis (PVNS) and giant cell tumor of the tendon sheath (GCT-TS). It also has received Orphan Designation from the European Commission for the treatment of TGCT.
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.

Prucalopride is a novel enterokinetic compound and is the first representative of the benzofuran class. Prucalopride is a potent, selective and specific serotonin 5-HT4 receptor (5-HT4-R) agonist. Prucalopride (Resolor®), a highly selective serotonin 5-HT4 receptor agonist, is indicated in the European Economic Area for the treatment of adults with chronic idiopathic constipation (CIC) in whom laxatives have failed to provide adequate relief.
