Volixibat (SHP626; formerly LUM002) is a potent inhibitor of the apical sodium-dependent bile acid transporter (ASBT) that was developed for the treatment of nonalcoholic steatohepatitis. Volixibat participated in phase II clinical trial to investigate its safety, effectiveness in adults with nonalcoholic steatohepatitis. However, this study was discontinued, without any further explanation for the possible causes. In addition, volixibat was studied in a clinical trial in healthy adults and in patients with type 2 diabetes mellitus, where was shown that the drug was generally well tolerated.

JNJ-42396302 was under investigation in clinical trial NCT01732237 (A Study to Investigate the Pharmacokinetics of JNJ-42396302, JNJ-53773187, and JNJ-42692507 in Healthy Male Participants).

Pexmetinib (ARRY-614) is a potent, orally bioavailable, dual p38 MAPK/Tie-2 inhibitor with potential antineoplastic, anti-inflammatory and antiangiogenic activities. Pexmetinib inhibited leukemic proliferation, prevented activation of downstream effector kinases and abrogated the effects of TNF-alpha on healthy hematopoietic stem cells. In ex vivo stimulated human whole blood, LPS-induced cytokines was inhibited by Pexmetinib with an IC50 value ranging from 50-120 nM. ARRY-614 inhibited the release of IL-6 from SEA- or LPS-challenged mice with an ED50 value less than 10 mg/kg. Combining Pexmetinib with lenalidomide inhibited both pro-inflammatory cytokines and tumor growth in vivo with higher potency, compared with either agent alone. In dose escalation or expansion cohorts, treatment with Pexmetinib either once daily or twice daily was applied to forty-five patients. Pexmetinib reduced the levels of circulating biomarkers and the p38 MAPK activation of bone marrow.

Seletalisib (UCB-5857) is a potent, ATP-competitive, and selective phosphoinositide 3-kinase (PI3K) delta inhibitor. Findings from cellular assays of adaptive immunity demonstrated that seletalisib blocks human T-cell production of several cytokines from activated T-cells. Additionally, seletalisib inhibited B-cell proliferation and cytokine release. In human whole blood assays, seletalisib inhibited CD69 expression upon B-cell activation and anti-IgE-mediated basophil degranulation. Seletalisib safety, tolerability and pharmacokinetic/pharmacodynamic profiles support its continued clinical development in immune-inflammatory diseases. UCB Pharma is developing Seletalisib for the treatment of immune and inflammatory diseases including Activated PI3K delta Syndrome (APDS), Sjogren's syndrome and psoriasis.

Zoliflodacin (also known as AZD0914 or ETX0914) is a spiropyrimidinetrione with activity against bacterial type II topoisomerases that inhibits DNA biosynthesis and results in accumulation of double-strand cleavages in bacteria. This drug is being a DNA gyrase inhibitor, targeting Neisseria gonorrhoeae and is currently in phase II clinical trial in adults to treat uncomplicated urogenital gonorrhea.
