Secondary amyloidosis is a form of amyloidosis, that complicates chronic inflammatory disorders (mainly rheumatoid arthritis) and is characterized by the aggregation and deposition of amyloid fibrils composed of serum amyloid A protein, an acute phase reactant. Although spleen, suprarenal gland, liver and gut are frequent sites of amyloid deposition, the clinical picture is dominated by renal involvement.
Biomarker and diagnostic research for AA amyloidosis has been reported in the published literature.
No approved treatments are currently available for AA amyloidosis. An additional 2 compounds hold orphan drug designation.
While no drugs are FDA-approved specifically for AA amyloidosis, some of the following designated compounds may be used off-label in clinical practice. Treatment decisions should be made in consultation with a specialist familiar with this condition.
The following drugs have received orphan drug designation from the FDA for AA amyloidosis. Orphan designation reflects regulatory interest and does not indicate approval for treatment.

A new treatment for children aged 2 or older with sickle cell disease has been approved by the U.S. Food & Drug Administration. In a press release on Wednesday, the FDA announced it had approved Casgevy, the first gene therapy for children with sickle cell disease. (NewsNation) — A new treatment for children aged 2 or older with sickle cell disease has been approved by the Food & Drug Administration (FDA). In a Wednesday news release, the FDA announced it had approved Casgevy, the first gene therapy for children with the disease. “Casgevy is a gene therapy consisting of the patient’s own (autologous) hematopoietic (blood) stem cells, administered as a one-time single dose for intravenous infusion,” the release noted. “Pediatric patients as young as 2 years of age can now access a critical additional treatment option to treat these debilitating, life-threatening diseases,” Karim Mikhail, the acting director of the Center for Biologics Evaluation and Research, wrote. “These disorders carry a heavy burden for children and their families, affecting growth, development, and long-term health in profound ways,” Megha Kaushal, acting deputy director of the Office of Therapeutic Products in CBER, said in the release.
