The Food and Drug Administration (FDA) has granted Orphan Drug Designation to olinciguat (Ironwood Pharmaceuticals) for the treatment of sickle cell disease.

Olinciguat is a soluble guanylate cyclase stimulator currently in Phase 2 development. The Company is enrolling patients in the STRONG-SCD trial which will evaluate the safety and tolerability of 3 dose levels of olinciguat compared with placebo when administered daily for approximately 12 weeks to patients with stable sickle cell disease. 

In non-clinical studies, this investigational agent has been shown to modulate the nitric oxide/soluble guanylate cyclase/cyclic guanosine monophosphate signaling pathway which is believed to be implicated in sickle cell disease.
