Briciclib (also known as ON-013105 and ON-014185) has the potential of targeting and inhibition of eukaryotic translation initiation factor 4E (eIF4E) for solid cancers. eIF4E is a proto-oncogene that promotes translation of several genes essential for cellular proliferation (cyclin D1, c-Myc, mTOR), survival (Akt), angiogenesis (VEGF), and metastasis (MMP9). Overexpression of eIF4E has been observed in almost all major groups of cancers and has been shown to induce increased expression of cyclin D1 and c-Myc). An intravenous formulation of briciclib was being investigated in the Phase 1 clinical trial. The purpose of the study was to determine the highest dose of briciclib that could be given safely in patients with relapsed/refractory Lymphoma or B-cell Acute Lymphocytic Leukemia (Philadelphia chromosome negative). However, this study was terminated because of the lack of available clinical drug supply. In addition, briciclib was also involved in phase I clinical trials with advanced cancer and solid tumors, to determine the highest dose that can be safely given.
