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.

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.

Binimetinib (MEK162) is an oral small-molecule with potential antineoplastic activity. It is a selective mitogen-activated protein kinase 1 and 2 (MEK1/2) inhibitor, a key protein kinase in the RAS/RAF/MEK/ERK pathway, which regulates several key cellular activities including proliferation, differentiation, migration, survival and angiogenesis. Inappropriate activation of this pathway has been shown to occur in many cancers, in particular through mutations in BRAF, KRAS and NRAS. MEK162 at 6 mg/kg, BID combined with BEZ235 (dual PI3K/mTOR inhibitor) resulted in a significant reduction of tumor growth in immunodeficient mice injected with MCF7 cells. There are three ongoing Phase 3 trials with binimetinib in advanced cancer patients: NEMO (NRAS-mutant melanoma), COLUMBUS (encorafenib in combination with binimetinib in BRAF-mutant melanoma) and BEACON CRC (encorafenib, binimetinib and cetuximab in BRAF-mutant colorectal cancer).

Bictegravir is a component of the fixed-dose combination product bictegravir/emtricitabine/tenofovir alafenamide (BIKTARVY®), which received marketing approval for the treatment of human immunodeficiency virus (HIV) infection by the U.S. Food and Drug Administration in February 2018. Bictegravir inhibits the strand transfer activity of HIV-1 integrase, an HIV-1 encoded enzyme that is required for viral replication. Inhibition of integrase prevents the integration of linear HIV-1 DNA into host genomic DNA, blocking the formation of the HIV-1 provirus and propagation of the virus.

Omadacycline is a tetracyclin-derivative antibiotic, originated in Tufts University, and later co-developed by Merck and Paratek Pharmaceuticals. The drug was approved for treatment of community-acquired pneumonia, and for treatment of acute bacterial skin and skin structure infections. Omadacycline tosylate is available as tablets and in injectable form.

Tecovirimat (ST-246) is a low-molecular-weight compound (molecular weight = 376), that is potent (concentration that inhibited virus replication by 50% = 0.010 microM), selective (concentration of compound that inhibited cell viability by 50% = >40 microM), and active against multiple orthopoxviruses, including vaccinia, monkeypox, camelpox, cowpox, ectromelia (mousepox), and variola viruses. The antiviral activity is specific for orthopoxviruses and the compound does not inhibit the replication of other RNA- and DNA-containing viruses or inhibit cell proliferation at concentrations of compound that are antiviral. ST-246 targets vaccinia virus p37, a viral protein required for envelopment and secretion of extracellular forms of virus. The compound is orally bioavailable and protects multiple animal species from lethal orthopoxvirus challenge. rug substance and drug product processes have been developed and commercial scale batches have been produced using Good Manufacturing Processes (GMP). Human phase I clinical trials have shown that ST-246 is safe and well tolerated in healthy human volunteers. Based on the results of the clinical evaluation, once a day dosing should provide plasma drug exposure in the range predicted to be antiviral based on data from efficacy studies in animal models of orthopoxvirus disease.

Delafloxacin (CAS registry number 189279-58-1) was described as WQ-3034 by Wakunaga Pharmaceutical Co., Ltd., Osaka & Hiroshima, Japan. It was first licensed in 1999 to Abbott Park, IL, and further developed as ABT-492. Delafloxacin (Baxdela), a fluoroquinolone antibiotic, is currently being developed by Melinta Therapeutics. It is a novel investigational fluoroquinolone in development for the treatment of uncomplicated gonorrhea, and acute bacterial skin and skin structure infections. Delafloxacin shows MICs remarkably low against Gram-positive organisms and anaerobes and similar to those of ciprofloxacin against Gram-negative bacteria. It remains active against most fluoroquinolone-resistant strains, except enterococci. Its potency is further increased in acidic environments (found in many infection sites). Delafloxacin is active on staphylococci growing intracellularly or in biofilms. Delafloxacin is a dual-targeting fluoroquinolone, capable of forming cleavable complexes with DNA and topoisomerase IV or DNA gyrase and of inhibiting the activity of these enzymes in both Gram-positive and Gram-negative bacteria. On Oct 24, 2016, Melinta Therapeutics Submitted Baxdela New Drug Application for hospital-treated skin infections.

Enasidenib, aslo known as AG-221 and CC-90007, is a potent and selective IDH2 inhibitor with potential anticancer activity (IDH2 = Isocitrate dehydrogenase 2). The mutations of IDH2 present in certain cancer cells result in a new ability of the enzyme to catalyze the NAPH-dependent reduction of α-ketoglutarate to R(-)-2-hydroxyglutarate (2HG). The production of 2HG is believed to contribute to the formation and progression of cancer. The inhibition of mutant IDH2 and its neoactivity is therefore a potential therapeutic treatment for cancer. Enasidenib is an orally available, selective, potent inhibitor of the mutated IDH2 protein, making it a highly targeted investigational medicine for the potential treatment of patients with cancers that harbor an IDH2 mutation. Enasidenib has received orphan drug and fast track designations from the U.S. FDA. Enasidenib mesylate is in phase II clinical trials for Solid tumours and phase III clinical trials for the treatment of acute myeloid leukaemia.

Naldemedine (Symproic) is an opioid antagonist indicated for the treatment of opioid-induced constipation (OIC) in adult patients with chronic non-cancer pain. Naldemedine is an opioid antagonist with binding affinities for mu-, delta-, and kappa-opioid receptors. Naldemedine functions as a peripherally-acting mu-opioid receptor antagonist in tissues such as the gastrointestinal tract, thereby decreasing the constipating effects of opioids. Naldemedine is a derivative of naltrexone to which a side chain has been added that increases the molecular weight and the polar surface area, thereby reducing its ability to cross the blood-brain barrier (BBB). Naldemedine is also a substrate of the P-glycoprotein (P-gp) efflux transporter. Based on these properties, the CNS penetration of naldemedine is expected to be negligible at the recommended dose levels, limiting the potential for interference with centrally-mediated opioid analgesia. Naldemedine was approved in 2017 in both the US and Japan for the treatment of Opioid-induced Constipation.

Ertugliflozin (PF-04971729) is a potent and selective sodium-dependent glucose cotransporter 2 (SGLT2) inhibitor incorporating a unique dioxa-bicyclo[3.2.1]octane (bridged ketal) ring system. SGLT2 has become an important therapeutic target and several SGLT2-selective inhibitors are either approved or in clinical development for the management of blood glucose in patients with type 2 diabetes. Ertugliflozin demonstrated robust urinary glucose excretion in rats and an excellent preclinical safety profile. It was announced that FDA and EMA filing acceptances of three marketing applications for ertugliflozin-containing medicines for adults with type 2 diabetes.
