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.
Letermovir (AIC246 or MK-8228), a 3,4-dihydro-quinazoline- 4-yl-acetic acid derivative, is the prototype viral terminase complex inhibitor that is most advanced in its clinical development. The novel compound was initially developed by AiCuris. In April 2011, the drug was granted orphan drug designation for prevention of CMV disease by the European Commission. In August 2011, the US Food and Drug Administration granted it a fast track designation. In 2012, the results of Phase IIb clinical trials using letermovir in bone marrow transplant patients were presented at various international meetings, and the data were subsequently published in 2014.42 It`s continued clinical development is currently undertaken in agreement with Merck. Letermovir is highly potent in vitro and in vivo against cytomegalovirus. Because of a distinct mechanism of action, it does not exhibit cross-resistance with other antiviral drugs. It is predicted to be active against strains that are resistant to ganciclovir, foscarnet, and cidofovir. To date, early-phase clinical trials suggest a very low incidence of adverse effects. It targets the UL56 subunit of the viral terminase complex. Letermovir is currently in Phase III development.
Telotristat (telotristat etiprate) is an ethyl ester prodrug which is hydrolyzed to its active moiety LP-778902 both in vivo and in vitro. Telotristat etiprate is an orally bioavailable, small-molecule, tryptophan hydroxylase (TPH) inhibitor. It is the first investigational drug in clinical studies to target TPH, an enzyme that triggers the excess serotonin production within metastatic neuroendocrine tumor (mNET) cells leading to carcinoid syndrome. Unlike existing treatments of carcinoid syndrome which reduce the release of serotonin outside tumor cells, telotristat etiprate reduces serotonin production within the tumor cells. By specifically inhibiting serotonin production telotristat may provide patients with more control over their disease. Telotristat etiprate has received Fast Track and Orphan Drug designation from the U.S. Food and Drug Administration and has been granted priority review by the FDA with a Prescription Drug User Fee Act (PDUFA) target action date of February 28, 2017.
Neratinib (HKI-272) is a pan-HER inhibitor, this irreversible tyrosine kinase inhibitor binds and inhibits the tyrosine kinase activity of epidermal growth factor receptors, EGFR (or HER1), HER2 and HER4, which leads to reduced phosphorylation and activation of downstream signaling pathways. Neratinib is a modified form of the discontinued compound pelitinib, and was originally being develoAdditionally, phase II development of oral neratinib as a neoadjuvant therapy for breast cancer, as a second-line therapy for non-small cell lung cancer, and for other solid tumours is also in progress in numerous countries worldwide. ped by Wyeth (later Pfizer). Oral neratinib is awaiting approval as an extended adjuvant therapy for breast cancer in the EU and in the US. Blocking HER2 function by a small molecule kinase inhibitor, such as neratinib, represents an attractive alternate strategy for the growth inhibition of HER2-positive tumours.
Venetoclax (trade name Venclexta, also known as ABT-199) is a selective and orally bioavailable small-molecule inhibitor of BCL-2, an antiapoptotic protein. BCL-2 and its related proteins BCL-XL and MCL-1 bind to and sequester pro-apoptotic signals in the cell, causing a down-regulation of apoptosis. As an oncogene and an important regulator of apoptosis, BCL-2 overexpression therefore results in increased tumor cell survival and resistance to chemotherapy. FDA approved Venetoclax in April 2016 for the treatment of patients with chronic lymphocytic leukemia (CLL) with 17p deletion, as detected by an FDA approved test, who have received at least one prior therapy. Also this drug in phase 3 clinical trial in combination therapy for the treatment patients with refractory myeloma and Acute Myeloid Leukemia. Common side effects include neutropenia, nausea, anemia, diarrhea, upper respiratory tract infection. Major side effects include tumor lysis syndrome and severe neutropenia.

Elbasvir is an inhibitor of the Hepatitis C Virus (HCV) Non-Structural protein 5A (NS5A). Elbasvir was approved by the FDA in January 2016 for the treatment of hepatitis C. It was developed by Merck and completed Phase III trials, used in combination with the NS3/4A protease inhibitor grazoprevir under the trade name Zepatier. Zepatier is indicated for treatment of chronic HCV genotype 1 or 4 infection in adults.

Lifitegrast (under brand name Xiidra) was approved as an ophthalmic solution for the treatment of the signs and symptoms of dry eye disease. Lifitegrast binds to the integrin lymphocyte function-associated antigen-1 (LFA-1); a cell surface protein found on leukocytes and blocks the interaction of LFA-1 with its cognate ligand intercellular adhesion molecule-1 (ICAM-1). This LFA-1/ICAM-1 interaction is a key step in the inflammatory cascade that contributes to dry eye disease. Besides lifitegrast participates in phase II clinical trials for prevention of the signs and symptoms of allergic conjunctivitis.
Rucaparib is a poly (ADP-ribose) polymerase (PARP) inhibitor indicated for the treatment of advanced mutant BRCA ovarian cancer. Rucaparib is being investigated in clinical trials against prostate cancer, breast cancer and other neoplasms.

Pimavanserin, marketed under the trade name Nuplazid, a non-dopaminergic atypical antipsychotic developed by Acadia Pharmaceuticals is the first and only medication approved by the U.S. Food and Drug Administration (FDA) for the treatment of hallucinations and delusions associated with Parkinson’s disease psychosis. The mechanism of action of pimavanserin in the treatment of hallucinations and delusions associated with Parkinson’s disease psychosis is unknown. However, the effect of pimavanserin could be mediated through a combination of inverse agonist and antagonist activity at serotonin 5-HT2A receptors and to a lesser extent at serotonin 5-HT2C receptors. In vitro, pimavanserin acts as an inverse agonist and antagonist at serotonin 5-HT2A receptors with high binding affinity (Ki value 0.087 nM) and at serotonin 5-HT2C receptors with lower binding affinity (Ki value 0.44 nM). Pimavanserin shows low binding to sigma 1 receptors (Ki value 120 nM) and has no appreciable affinity (Ki value >300 nM), to serotonin 5-HT2B, dopaminergic (including D2), muscarinic, histaminergic, or adrenergic receptors, or to calcium channels. Pimavanserin was approved by the FDA to treat hallucinations and delusions associated with psychosis experienced by some people with Parkinson's disease on April 29, 2016.
