The FDA approved Ironwood Pharmaceuticals’ fixed-dose combination of lesinurad and allopurinol (Duzallo) on August 21, 2017.1

Duzallo is indicated for the treatment of hyperuricemia in patients with uncontrolled gout. The drug, designed to achieve target serum uric acid (sUA) levels in patients who cannot do so with allopurinol alone, is the first FDA-approved fixed-dose combination oral treatment that addresses both over-production and under-excretion of sUA in a single medication.

The most common adverse events associated with the use of Duzallo include headache, influenza, higher levels of blood creatinine, and heartburn. The drug also has a boxed warning alerting patients and providers to a risk of acute renal failure.

Ironwood Pharmaceuticals plans to launch Duzallo in the United States during the fourth quarter of 2017.

The drug is to be used alongside the RealTime IDH2 Assay, a companion diagnostic from Abbott Laboratories that is used to detect specific mutations in the IDH2 gene in patients with AML.

Common adverse events reported by trail patients treated with Idhifa include nausea, vomiting, diarrhea, increased levels of bilirubin, and decreased appetite. The drug should not be used by pregnant women.

The drug can also be used to treat adult patients with an HCV genotype 1 infection who have been previously treated with a regimen either containing an NS5a inhibitor or an NS3/4A protease inhibitor, but not both.

The most common adverse events associated with the use of Mavyret include headache, fatigue, and nausea. The drug’s is contraindicated in patients with severe cirrhosis, and its use is not recommended in those with moderate cirrhosis.

Vabomere has been designated as a qualified infectious disease product, and should only be used to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria.

5. Victoza
The FDA expanded the indication of Novo Nordisk’s liraglutide (Victoza) on August 25, 2017.5
