CC-220 is a potent cereblon modulating agent that displays anti-proliferative, pro-apoptotic and immunomodulatory activity on sensitive and resistant multiple myeloma cell lines. CC-220 is currently under clinical investigation for systemic lupus erythematosus and multiple myeloma as a single agent, or in combination with dexamethasone in patients who may have previously been exposed to pomalidomide. Comparable to other Cereblon-binding agents, ex vivo treatment of CC-220 on B-cells, T-cells, and monocytes leads to the degradation of the hematopoietic transcription factors Ikaros (IKZF1) and Aiolos (IKZF3). followed by disruption of the multiple myeloma promoting c-Myc/IRF4 axis.

ASC-09 orTMC-310911, a HIV protease inhibitor, participated in phase II clinical for the treatment of Human Immunodeficiency Virus Type 1. However, no recent development has been reported.

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.

Etripamil is a non-dihydropyridine, L-type calcium channel blocker. Currently, etripamil is in Phase 3 development for the treatment of paroxysmal supraventricular tachycardia. Milestone Pharmaceuticals is also developing etripamil to provide rapid heartbeat control for patients living with atrial fibrillation and acute symptom relief for patients with angina.

E-6005 is a novel PDE4 inhibitor developed as a topical agent for atopic dermatitis (AD). It potently and selectively inhibited human PDE4 activity and suppressed the production of various cytokines from human lymphocytes and monocytes. In mice models, the topical application of E6005 produced an immediate antipruritic effect as well as an anti-inflammatory effect with reduced expression of cytokines/adhesion molecules. E-6005 increases the cutaneous concentration of cAMP to relieve dermatitis-associated itching. E-6005 may be a promising novel therapeutic agent with antipruritic activity for the treatment of AD. E-6005 is currently in phase 2 development for patients with mild-to-moderate atopic dermatitis.

Allocupreide is a copper(l) complex used as an antiinflammatory drug and antiarthritic agent. It was used for the treatment of trigeminal neuralgia.
