Zymedi Gets Orphan Status for ZMA001
FDA has granted Zymedi an orphan drug designation for ZMA001, a proposed first-in-class antibody treatment in development for pulmonary arterial hypertension (PAH), an inflammatory vascular disease that the company says is characterized by the remodeling and narrowing of pulmonary arterioles due to various causes. “The infiltration of immune cells from the blood into the lungs damages the pulmonary system, increases pulmonary arterial pressure, and ultimately leads to right ventricular failure and death, with a survival rate comparable to cancer,” Zymedi says. Currently, most treatments involve vasodilators, which alleviate symptoms without curing the condition, it says.
ZMA001 is described as a human monoclonal antibody that blocks the infiltration of inflammation-inducing macrophages into the lungs, thus inhibiting the symptoms of PAH from the early stages. “Notably, ZMA001 has shown a synergistic effect when used in conjunction with existing medications, positioning it as a potential game-changer in PAH treatment, where innovative drugs are urgently needed,” Zymedi says.
ZMA001 is currently undergoing a Phase 1a clinical trial at NIH that began in January to evaluate the drug’s safety/tolerability and to determine the appropriate dosages and identify any potential side effects, according to the company.
