Encenicline (EVP-6124; MT-4666) acts as a potent partial and selective agonist at alpha-7 nicotinic acetylcholine receptor. Encenicline significantly improved memory function in animal models. FORUM Pharmaceuticals (formerly EnVivo Pharmaceuticals) is developing encenicline for the treatment of cognition disorders such as schizophrenia and for Alzheimer's disease.

Ilorasertib (previously known as ABT-348), an orally bioavailable ATP-competitive inhibitor of Aurora kinases (A, B and C), as well as the VEGF and PDGF families of receptor tyrosine kinases, was developed by AbbVie as an antineoplastic agent. It is known that Aurora kinases A, B, and C play essential roles in mitotic checkpoint control and are overexpressed by a wide variety of tumor cell types. Both VEGFRs and PDGFRs may be upregulated in various tumor cell types. Ilorasertib alone or in combination with azacitidine demonstrated activity in preclinical models in various hematological malignancies, indicating that pan-Aurora kinase and multiple kinase inhibition may have preferential antileukemic activity. Ilorasertib participated in phase I clinical for patients with advanced hematologic malignancies. The result has shown that the drug could be further studied in acute myelogenous leukemia. Ilorasertib is also going to be studied in phase II clinical trials to learn if this drug can help to control CDKN2A-deficient cancer in patients with advanced cancers.

FLUCICLATIDE F-18 is an 18F-radiolabelled synthetic cyclic peptide containing an RGD motif (Arg-Gly-Asp). It may be used as a tracer in positron emission tomography (PET) imaging. The RGD motif of FLUCICLATIDE F-18 selectively binds to the alpha-V/beta-3 integrin, upregulated on tumor cells and endothelial cells of tumor vasculature. Integrins play an important role in tumor angiogenesis and metastasis. Thus, FLUCICLATIDE F-18 is a potential biomarker of therapeutic response to antiangiogenic inhibitors.

BMS-986094 (formerly known as INX-189), a nucleotide polymerase (NS5B) inhibitor was developed for the treatment of hepatitis C. Drug participated in phase II clinical trials to evaluate its safety and tolerability. However, in 2012 Bristol-Myers Squibb announced discontinues the development due to safety reasons. The U.S. Food and Drug Administration (FDA) subsequently placed BMS-986094 on clinical hold.

PF-05089771 is an oral administrated Nav1.7 channel inhibitor. PF-05089771 provided the best opportunity to explore Nav1.7 blockade for the treatment of acute or chronic pain conditions. PF-05089771 has completed Phase II clinical trials of third molar extraction and primary inherited erythromelalgia. The magnitude of efficacy of PF-05089771 in the randomized, placebo-controlled, double-blind clinical study in subjects with painful diabetic peripheral neuropathy was disappointing. Although there was a trend towards a reduction in pain and improvement in sleep rating in patients with painful DPN when compared to placebo treatment, this was not statistically significant.

Peficitinib (formerly known as ASP015K) is a pyrrolo[2,3-b]pyridine derivative orally administered once-daily JAK inhibitor in development for the treatment of Rheumatoid Arthritis. In preclinical studied Peficitinib inhibited JAK1 and JAK3 with IC50 of 3.9 and 0.7 nM, respectively. Peficitinib also inhibited IL-2-dependent T cell proliferation in vitro and STAT5 phosphorylation in vitro and ex vivo. Furthermore, Peficitinib dose-dependently suppressed bone destruction and paw swelling in an adjuvant-induced arthritis model in rats via prophylactic or therapeutic oral dosing regimens.In clinical trials, Peficitinib treatment prescribed at 50, 100 and 150 mg amounts each showed statistically significantly higher ACR20 response rates compared to the placebo and response rates increased up to the 150 mg dosage. Adverse events included neutropenia, headache, and abdominal pain. The treatment-emergent adverse events occurring more frequently in the Peficitinib group compared with the placebo group included diarrhea, nasopharyngitis, and increased serum creatine phosphokinase activity. No cases of serious infections were reported. Herpes zoster occurred in four patients (two each in the peficitinib 25 and 100 mg cohorts). The authors concluded that treatment with peficitinib as monotherapy for 12 weeks in Japanese patients with moderate to severe RA is efficacious and showed an acceptable safety profile.

PF-04958242 is an AMPA receptor potentiator for the potential treatment of cognitive deficits in schizophrenia. But recent study revealed that there were no pharmacokinetic interactions between PF-04958242 and ketamine. 'High-impact' AMPAR potentiators like PF-04958242 may have a role in the treatment of the cognitive symptoms, but not the positive or negative symptoms, associated with schizophrenia. In addition, a clinical study was underway to evaluate the effects of PF-049582432 in subjects with age-related hearing loss in the US. PF-04958242 has been classified as glycine transporter (GLYT-1) inhibitor in this study. However, this development was discontinued.
