Dacomitinib is an oral, once-daily, pan-HER inhibitor. It is an irreversible inhibitor of HER-1 (EGFR), HER-2 and HER-4 tyrosine kinases. Dacomtinib is being evaluated in phase 3 clinical trials against nonsmall-cell lung cancer. Direct comparison with erlotinib did not show superiority of dacomtinib, but subgroup analysis have demonstrated that subgroup with exon 19 deletion had favorable outcomes with dacomitinib. In addition to nonsmall-cell lung cancer dacomtinib is being evaluated against esophagus, head and neck and other neoplasms. Due to its ability to pass through blood-brain barrier, dacomitinib can be used to treat brain tumors.

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.

Deflazacort is a glucocorticoid developed for the treatment of different inflammatory and immune conditions. The drug is rapidly metabolized to an active metabolite, 21-hydroxy-deflazaxort that may cross the blood brain barrier. Deflazacort acts by suppressing inflammatory response.

Safinamide (FCE 26743, NW 1015, PNU 151774, PNU 151774E, trade name Xadago) combines potent, selective, and reversible inhibition of MAO-B with blockade of voltage-dependent Na+ and Ca2+ channels and inhibition of glutamate release. Safinamide is under development with Newron, Zambon and Meiji Seika Pharma for the treatment of Parkinson's disease. Safinamide has been launched in the EU, Iceland and Liechtenstein. Safinamide was well tolerated and safe in the clinical development program that demonstrated the amelioration of motor symptoms and OFF phenomena by safinamide when combined with dopamine agonists or levodopa.

Acalabrutinib, also known as ACP-196, is a novel irreversible second-generation Bruton’s tyrosine kinase (BTK) inhibitor, which prevents the activation of the B-cell antigen receptor (BCR) signaling pathway and that, was rationally designed to be more potent and selective than ibrutinib. This drug in clinical trials phase III for treatment the treatment of relapsed chronic lymphocytic leukemia. Also in combination with others drugs, Acalabrutinib in phase II of clinical trials for the treatment Glioblastoma Multiforme, Mantle Cell Lymphoma, Squamous Cell Carcinoma of the Head and Neck, Rheumatoid Arthritis and some others.

Deutetrabenazine (trade name Austedo) is a vesicular monoamine transporter 2 (VMAT2) inhibitor indicated for the treatment of chorea associated with Huntington’s disease. The drug was developed by Auspex Pharmaceuticals and is being commercialized by Teva Pharmaceuticals. Deutetrabenazine is a deuterated derivative of tetrabenazine. The incorporation of deuterium in place of hydrogen at the sites of primary metabolism results in metabolic clearance being slowed, allowing less frequent dosing and better tolerability.

Niraparib (MK-4827) displays excellent PARP 1 and 2 inhibition. Inhibition of PARP in the context of defects in other DNA repair mechanisms provide a tumor specific way to kill cancer cells. Niraparib is in development with TESARO, under licence from Merck & Co, for the treatment of cancers (ovarian, fallopian tube and peritoneal cancer, breast cancer, prostate cancer and Ewing's sarcoma). Niraparib was characterized in a number of preclinical models before moving to phase I clinical trials, where it showed excellent human pharmacokinetics suitable for once a day oral dosing, achieved its pharmacodynamic target for PARP inhibition, and had promising activity in cancer patients. It is currently being tested in phase 3 clinical trials as maintenance therapy in ovarian cancer and as a treatment for breast cancer.

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.

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.

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.
