Duvyzat is indicated for the treatment of Duchenne muscular dystrophy (DMD) in ambulant patients, aged 6 years and older, and with concomitant corticosteroid treatment.
Treatment with givinostat should be initiated by a physician experienced in the management of Duchenne muscular dystrophy.
Baseline platelet counts and triglycerides should be obtained and evaluated prior to initiation of givinostat. Givinostat should not be initiated in patients with a platelet count less than 150 x 109/l. Platelet counts and triglycerides should be monitored as recommended during treatment to determine if dosage modifications are needed (see section 4.4 and dose adjustment instructions below).
In addition, in patients with underlying cardiac disease or taking concomitant medicines that cause QT prolongation, an ECG should be obtained when initiating treatment with givinostat, during concomitant use, and as clinically indicated (see section 4.4).
The recommended dose of givinostat is based on body weight and should be administered orally twice daily (see Table 1).
