FDA Grants Imara Pediatric Disease Status for Sickle Cell Therapy
FDA has granted Imara a rare pediatric disease designation for IMR-687, the company’s lead product candidate for treating sickle cell disease. The company is conducting a Phase 1a clinical study to evaluate the safety and pharmacokinetics of IMR-687 in healthy volunteers. In addition, it will assess pharmacodynamic markers. Pending a positive outcome of the study this summer, Imara will initiate a Phase 2a study in adult patients with sickle cell disease later this year and then expects to initiate a Phase 2 pediatric patient study in 2018.
IMR-687 was designed to address the underlying pathology of sickle cell disease, according to Imara. “An orally-administered, highly potent and selective phosphodiesterase 9 (PDE9) inhibitor, IMR-687 is a potentially disease-modifying therapeutic for sickle cell disease as well as other hemoglobinopathies,” it says. “Pre-clinical data demonstrate IMR-687 reduces both the sickling of red blood cells and blood vessel occlusion that cause debilitating pain, organ damage, and early mortality in affected patients.”
