VTP-27999 is an alkyl amine renin inhibitor. This compound demonstrated excellent selectivity over related and unrelated off-targets, >15% oral bioavailability in three species, oral efficacy in a double transgenic rat model of hypertension, and good exposure in humans. Vitae Pharmaceuticals was developing VTP 27999 for the treatment of chronic kidney disease. VTP 27999 was in phase I clinical development in the US. However, the product is no more on the company pipeline and it appears that the development has been discontinued.

N-[2-[(2-amino-2-oxoethyl)-[3-(2-oxopyrrolidin-1-yl)propyl]amino]-2-oxoethyl]-2-[2-(2-fluorophenyl)ethylamino]-N-(2-methylpropyl)acetamide (BN201) is a small peptide molecule, a first-in-class neuroprotective compound. BN201 promotes the survival of cultured neural cells when subjected to oxidative stress or when deprived of trophic factors. BN201 promotes neuronal differentiation, the differentiation of precursor cells to mature oligodendrocytes in vitro, and the myelination of new axons. BN201 modulates several kinases participating in the insulin growth factor 1 pathway including serum-glucocorticoid kinase and midkine, inducing the phosphorylation of NDRG1 and the translocation of the transcription factor Foxo3 to the cytoplasm. In vivo, BN201 prevents axonal and neuronal loss, and it promotes remyelination in models of multiple sclerosis, chemically induced demyelination, and glaucoma. Bionure, a spin-off from Hospital Clínic de Barcelona that is based in California, is developing BN201 for multiple sclerosis, acute optic neuritis (AON) and glaucoma. BN201 was granted with orphan designation status for optic neuritis by the FDA. Optic neuritis is often an early sign of multiple sclerosis. The efficacy, safety, and capacity of the drug to cross the blood-brain barrier have been demonstrated in animal models, but the drug has not yet entered clinical testing.

H3B-6527 is a highly selective covalent FGFR4 inhibitor with at least 250-fold selectivity over FGFR1-3. H3B-6527 inhibits FGFR4 signaling, proliferation, and leads to apoptosis in Hepatocellular carcinoma (HCC) cell line. Treatment on Hep3B cells leads to robust activation of caspase-3/7, an apoptotic marker, in a concentration-dependent manner, indicating FGFR4 inhibition by H3B-6527 leads to cell death in HCC cell lines. In the Hep3B human HCC xenograft mouse model, H3B-6527 shows dose-proportional plasma exposures and greater than dose-proportional tumor exposures within the dose range evaluated (30, 100, and 300 mg/kg). Oral treatment of H3B-6527, twice daily, inhibits xenograft growth in a dose-dependent manner in nude mice, with the 300 or 100 mg/kg twice daily, significantly inhibiting tumor growth in both Hep3B subcutaneous and orthotopic xenograft model and causing tumor regressions in the subcutaneous xenograft model.

MGB-BP 3 is an antibacterial agent being developed by MGB Biopharma. This drug is now in phase II clinical trial to assess the safety, tolerability, and efficacy of incremental doses in patients with Clostridium difficile-associated diarrhea. In addition, this drug is studied for the treatment of Gram-positive infections; and skin and soft tissue infections.

AZD0424, a dual selective Src/Abl kinase inhibitor that has shown evidence of anti-tumor activity in pre-clinical studies. AZD0424 participated in phase I clinical trials in patients with advanced solid tumors, but this study was terminated because of insufficient evidence of efficacy as monotherapy.

Cenerimod is an orally available sphingosine-1-phosphate receptor 1 (S1P1) modulator that is being developed by Idorsia Pharmaceuticals for the treatment of systemic lupus erythematosus. Sphingosine-1-phosphate (S1P), a lipid mediator, regulates lymphocyte migration between lymphoid tissue and blood. Cenerimod is a potent, selective, safe and orally administrable S1P1 receptor modulator, which reportedly reduced blood lymphocytes and attenuated murine experimental autoimmune encephalomyelitis (EAE) in a murine model. Cenerimod has potential as novel therapy with an improved safety profile for autoimmune diseases with a high unmet medical need.
