Mitonafide is a nitro-containing antitumor drug. Mitonafide participated in clinical trials phase II in colorectal cancer patients, however, the results have shown that the drug was not active and induced severe myelotoxicity. Besides, the drug was involved in phase II for the patients with non-small cell lung cancer (NSCLC), where it was not active in spite of the safe administration. Information about the current development of this drug is not available.

PBI 4050, a synthetic analog of a medium-chain fatty acid that displays agonist and antagonist ligand affinity toward GPR40 and GPR84, that was developed for managing inflammatory and fibrosis-related diseases. In addition, PBI-4050 may exert antifibrotic activity in the liver through a novel mechanism of action involving modulation of intracellular ATP levels and the LKB1/AMPK/mTOR pathway in stellate cells. This drug participated in clinical trials for the treatment of acute lung injury, cystic fibrosis, diabetic nephropathies; idiopathic pulmonary fibrosis; metabolic syndrome; scleroderma; type 2 diabetes mellitus. Besides, this drug has granted a Rare Pediatric Disease Designation for the treatment of Alström syndrome (AS). PBI-4050 was also previously granted Orphan Drug Designation by the FDA and the EMA for the treatments of AS and idiopathic pulmonary fibrosis (IPF) as well as PIM (Promising Innovative Medicine) designation by the Medicines and Healthcare products Regulatory Agency (MHRA) for the treatment of IPF and AS. The FDA grants Rare Pediatric Disease Designations for serious or life-threatening diseases wherein the serious or life-threatening manifestations primarily affect individuals aged from birth to 18 years, including age groups, often called neonates, infants, children, and adolescents. Now Prometic Life Sciences plans to file investigational new drug application for pivotal phase III trial for Alstrom's syndrome in the second half of 2019.
