The US Food and Drug Administration (FDA) has granted approval for L-glutamine oral powder (Endari), the first treatment approved to treat sickle cell disease (SCD) in the US in nearly 20 years.

L-glutamine oral powder, a product developed by Emmaus Medical Inc., is intended to reduce severe complications of SCD in patients age 5 and older.

The FDA’s approval of L-glutamine was supported by efficacy data from a phase 3 trial.

The trial enrolled 230 adults and children with SCD, and they were randomized to receive L-glutamine or placebo.

Patients who received L-glutamine had fewer sickle cell crises, hospitalizations, cumulative hospital days, and cases of acute chest syndrome than patients who received placebo.

Results from this trial were presented at the 2014 ASH Annual Meeting.

The FDA approval of L-glutamine was also supported by safety data from 298 patients treated with L-glutamine and 111 patients treated with placebo in the phase 2 and phase 3 studies.

Based on these data, L-glutamine was considered well-tolerated in pediatric and adult patients. The most common adverse events (occurring in more than 10% of patients receiving L-glutamine) were constipation, nausea, headache, abdominal pain, cough, pain in extremity, back pain, and chest pain (non-cardiac).
