MBX-2982 is a potential first-in-class treatment for type 2 diabetes that targets G protein-coupled receptor 119 (GPR119), a receptor that interacts with bioactive lipids known to stimulate glucose-dependent insulin secretion. Preclinical data indicate that MBX-2982 is a potent selective orally-active GPR119 agonist that functions through a unique dual mechanism of action. First, it acts directly on the beta cell to increase insulin secretion. In addition, MBX-2982 stimulates release of the incretin GLP-1 from the gut. This dual action is unique and may offer improved glucose homeostasis over existing diabetes therapies, with potential for weight loss and improved islet health. MBX-2982 has completed four Phase 1 studies and one Phase 2 study. In the 4-week Phase 2 study in diabetics, MBX-2982 lowered mean weighted glucose and postprandial glucose during an extended mixed-meal tolerance test (MMTT). Treatment with MBX-2982 increased insulin, active GLP-1, and total GLP-1 during an extended MMTT. Treatment with MBX-2982 also tended to increase fasting insulin and c-peptide, and decrease fasting triglycerides. In all studies to date, MBX-2982 demonstrated dose-dependent increases in drug exposure with a profile supporting once daily oral dosing that was safe and well tolerated with no serious adverse events, adverse event trends or dose-limiting toxicities. These results provide clinical validation for the potential therapeutic benefits of MBX-2982 as a type 2 diabetes treatment.

MK-0812 is a potent and selective CCR2 antagonist, which was developed by Merck. This drug has entered clinical trials for both rheumatoid arthritis and multiple sclerosis. However, the rheumatoid arthritis trial was terminated because of lack of favorable outcomes when MK-0812 failed to show any early clinical improvement. The outcome of the multiple sclerosis trial of MK-0812 also had negative outcomes.
Lucitanib (E-3810) is a novel multi-kinase inhibitor currently in clinical trials for its anti-angiogenic and anti-tumor activity. A Phase I/IIa clinical trial of lucitanib was initiated in 2010 and has demonstrated multiple objective responses in FGFR1 gene-amplified breast cancer patients, and objective responses were also observed in patients with tumors often sensitive to VEGFR inhibitors, such as renal cell and thyroid cancer. Lucitanib is an oral, potent inhibitor of the tyrosine kinase activity of fibroblast growth factor receptors 1 through 3 (FGFR1-3), vascular endothelial growth factor receptors 1 through 3 (VEGFR1-3) and platelet-derived growth factor receptors alpha and beta (PDGFR alpha-beta). The most common adverse events were hypertension, asthenia, and proteinuria.

Sepranolone (UC1010) is a GABA-A modulating steroid antagonist (GAMSA) and does not antagonize the effect of GABA itself or other GABAA agonists like benzodiazepines and barbiturates. The interaction of neuroactive steroids (i.e., allopregnanolone and Sepranolone) with GABA-A receptor is particularly important in mood disorders. For example, allopregnanolone administration decreased saccadic eye velocity in healthy female volunteers and induced sedation and these effects were diminished by simultaneous sepranolone administration. Thus, allopregnanolone effects are antagonized by its isomer sepranolone. UC1010 reduces symptom severity and impairment significantly more efficiently than placebo in women with a well-defined, pure premenstrual dysphoric disorder. No severe adverse events were reported during the UC1010 treatment and safety parameters (vital signs and blood chemistry) remained normal during the study. It was revealed also that increases in ring A-reduced progesterone metabolites, particularly Sepranolone, are associated with chronic fatigue syndrome.

Dexmecamylamine (TC-5214, also known, as S isomer of mecamylamine) is a positive allosteric modulator of α4β2 neuronal nicotinic receptors, rather than an open-channel blocker. It was evaluated as a potential adjunct treatment for patients with major depressive disorder (MDD). TC-5214 was generally well tolerated, however, the studies were not supportive of an antidepressant effect for TC-5214 in patients with MDD and inadequate response to prior antidepressant therapy. The Phase 2b clinical trial of TC-5214 for the treatment for overactive bladder (OAB) revealed the high dose of TC-5214 demonstrated mixed results on the co-primary endpoints by providing a statistically significant reduction in micturition frequency and an improvement that did not reach statistical significance on episodes of urinary incontinence. As a consequence of these results, this drug was discontinuing further development of TC-5214 in OAB. The study for using TC-5214 in patients with refractory hypertension was also terminated.

Exherin is a small, cyclic pentapeptide vascular-targeting agent with potential antineoplastic and antiangiogenic activities. ADH-1 selectively and competitively binds to and blocks N-cadherin, which may result in disruption of tumor vasculature, inhibition of tumor cell growth, and the induction of tumor cell and endothelial cell apoptosis. In murine melanoma xenografts, ADH-1 in combination with melphalan significantly reduced tumor growth up to 30-fold over melphalan alone. ADH-1 enhancement of response to melphalan was associated with increased formation of DNA adducts, increased apoptosis, and intracellular signaling changes. In a pilot study (phase I trial), ADH-1 intravenous pretreatment before chemotherapy in metastatic melanoma completely destroyed tumors in half of patients

Nolpitantium (SR-140333) is a highly selective nonpeptide antagonist of neurokinin-1 (NK1) receptor. Nolpitantium potently, selectively and competitively inhibited substance P binding to NK1 receptors from various animal species, including humans. In vitro, it was a potent antagonist in functional assays for NK1 receptors such as [Sar9, Met(O2)11]substance P-induced endothelium-dependent relaxation of rabbit pulmonary artery and contraction of guinea-pig ileum. Up to 1 mkM, Nolpitantium had no effect in bioassays for NK2 and NK3 receptors. The antagonism exerted by Nolpitantium toward NK1 receptors was apparently non-competitive, with pD2' values between 9.65 and 10.16 in the different assays. Nolpitantium also blocked in vitro [Sar9, Met(O2)11]substance P-induced release of acetylcholine from rat striatum. In vivo, Nolpitantium exerted highly potent antagonism toward [Sar9, Met(O2)11]substance P-induced hypotension in dogs, bronchoconstriction in guinea-pig) and plasma extravasation in rats. Nolpitantium was found to be effective in the modulation of the inflammatory response and airway remodeling in mice. Nolpitantium is reported to cause antagonism of the SP-induced relaxations of human isolated intralobar pulmonary arterial rings. Nolpitantium also blocked the activation of rat thalamic neurons after nociceptive stimulation. Nolpitantium has been shown to reduce the severity of inflammation in trinitrobenzene sulfonic acid-induced colitis in the rat colon. Nolpitantium inhibited mustard oil-induced plasma protein extravasations in the dorsal skin of the rat hind paw. Nolpitantium had been in some phase II clinical trials but further studies were discontinued.

Gepotidacin (formerly GSK2140944) is a novel, first-in-class, triazaacenaphthylene antibacterial that selectively inhibits bacterial DNA gyrase and topoisomerase IV by a unique mechanism, one that is not utilized by any currently approved human therapeutic agent. As a consequence of its novel mode of action, gepotidacin is active in vitro against target pathogens carrying resistance determinants to established antibacterials, including fluoroquinolones. Gepotidacin has demonstrated in vitro activity against key pathogens, including drug-resistant strains, associated with a range of conventional and biothreat infections. GlaxoSmithKline is developing Gepotidacin for the treatment of gonorrhoea and skin and soft tissue infections.
