Fosmanogepix is an antifungal medication being studied for treating serious fungal infections. It works against various types of mold infections that can be difficult to treat with other medications. This new drug is specifically designed to fight against invasive infections caused by different types of molds, including Aspergillus, Fusarium, and other resistant fungi. It may provide a treatment option for patients who have limited choices due to drug resistance or who haven’t responded well to other antifungal treatments.

Invasive Mold Infection (IMI) – A serious fungal infection that occurs when certain types of molds invade deep tissues or organs in the body. The infection typically begins when a person inhales microscopic mold spores, which then spread beyond the respiratory system. Common causative molds include Aspergillus species, Fusarium species, Lomentospora prolificans, and Mucorales fungi. The infection can affect multiple organs and typically develops more frequently in people with weakened immune systems. The condition progresses by spreading through blood vessels and tissues, causing damage to affected organs.

Aspergillosis – A fungal infection caused by Aspergillus mold species that commonly starts in the respiratory system. The fungus can grow and spread within the lungs, forming masses of fungal fibers and inflammatory cells. In some cases, the infection can spread beyond the lungs to other parts of the body. The condition typically develops gradually, with symptoms becoming more noticeable as the infection progresses.

Fusariosis – An infection caused by Fusarium fungi that can affect various parts of the body. The infection commonly enters through damaged skin or through inhalation. Fusarium can spread throughout the body through the bloodstream. The infection may start on the skin or in the respiratory system before potentially spreading to other organs.

Mucormycosis – An infection caused by fungi of the Mucorales order that typically begins in the sinuses or lungs. The fungi can spread rapidly through blood vessels, causing tissue death in infected areas. The infection can progress to nearby structures including the eyes and brain. The condition develops relatively quickly compared to other fungal infections.
