Uses
1 INDICATIONS AND USAGE DUVYZAT is indicated for the treatment of Duchenne muscular dystrophy (DMD) in patients 6 years of age and older. DUVYZAT is a histone deacetylase inhibitor indicated for the treatment of Duchenne muscular dystrophy (DMD) in patients 6 years of age and older. ( 1 )
Dosage
2 DOSAGE AND ADMINISTRATION Obtain and evaluate baseline platelet counts and triglycerides prior to initiation of DUVYZAT. Do not initiate DUVYZAT in patients with a platelet count less than 150 x 10^9/L. ( 2.1 , 5.1 , 5.2 ) The dosage of DUVYZAT is based on patient’s body weight. ( 2.2 ) Administer orally twice daily with food. ( 2.2 ) Dosage modifications may be needed for decreased platelet counts, diarrhea, increased triglycerides, or QTc prolongation. ( 2.3 , 5.1 , 5.2 , 5.3 , 5.4 ) 2.1 Recommended Evaluation and Testing Before Initiation of DUVYZAT Obtain and evaluate baseline platelet counts and triglycerides prior to initiation of DUVYZAT [see Warnings and Precautions (5.1 , 5.2) ] . Do not initiate DUVYZAT in patients with a platelet count less than 150 x 10 9 /L.
Side Effects
6 ADVERSE REACTIONS The following clinically significant adverse reactions are described below and elsewhere in the labeling: Hematological Changes [see Warnings and Precautions (5.1) ] Increased Triglycerides [see Warnings and Precautions (5.2) ] Gastrointestinal Disturbances [see Warnings and Precautions (5.3) ] QTc Prolongation [see Warnings and Precautions (5.4) ] Most common adverse reactions (≥10% in DUVYZAT-treated patients) are diarrhea, abdominal pain, thrombocytopenia, nausea/vomiting, hypertriglyceridemia, and pyrexia. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact ITF Therapeutics, LLC. at 1-833-582-4312 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch .
Interactions
7 DRUG INTERACTIONS Closely monitor when DUVYZAT is used in combination with an oral CYP3A4 sensitive substrate or a sensitive substrate of the OCT2 transporter, for which a small change in substrate plasma concentration may lead to serious toxicities. ( 7.1 ) Avoid concomitant use with other drugs that prolong the QTc interval; monitor ECG if concomitant use cannot be avoided. ( 7.2 ) 7.1 Effect of DUVYZAT on Other Drugs CYP3A4 Sensitive Substrates Givinostat is a weak intestinal CYP3A4 inhibitor [see Clinical Pharmacology (12.3) ] . Closely monitor when DUVYZAT is used in combination with orally administered CYP3A4 sensitive substrates for which a small change in substrate plasma concentration may lead to serious toxicities.
Warnings
5 WARNINGS AND PRECAUTIONS Hematological Changes: DUVYZAT can cause dose-related thrombocytopenia and other signs of myelosuppression, including anemia and neutropenia. Monitor platelets; dosage adjustment or discontinuation may be needed. ( 2.3 , 5.1 ) Increased Triglycerides: An increase in triglycerides can occur; dosage modification may be needed. Discontinuation may be needed. ( 2.3 , 5.2 ) Gastrointestinal Disturbances: Adjust dosage if moderate or severe diarrhea occurs. Antiemetics or antidiarrheal medications may be considered during treatment with DUVYZAT. Discontinue DUVYZAT if the symptoms persist. ( 2.3 , 5.3 ) QTc Prolongation: Avoid use of DUVYZAT in patients who are at an increased risk for ventricular arrhythmias. 4 CONTRAINDICATIONS None. None. ( 4 )
Pregnancy
8.1 Pregnancy Risk Summary DUVYZAT is indicated for the treatment of DMD, which is a disease of predominantly young male patients. Therefore, there are no adequate data available to assess the use of DUVYZAT in pregnant women. In animal studies, oral administration of givinostat during organogenesis resulted in decreased fetal body weight and increased structural variations; oral administration during pregnancy and lactation resulted in increased embryofetal and offspring mortality and neurobehavioral changes in the offspring. In the U.S.
Storage
16.2 Storage and Handling Store at 20°C to 25°C (68°F to 77°F), excursions permitted to 15°C to 30°C (59°F to 86°F) [see USP Controlled Room Temperature]. Do not freeze. Store upright. Discard any unused DUVYZAT remaining after 60 days of first opening of the bottle.

Hydrolytic Lysosomal Glycosaminoglycan-specific Enzyme [EPC]
11 DESCRIPTION NAGLAZYME is a formulation of galsulfase, which is a purified human enzyme that is produced by recombinant DNA technology in a Chinese hamster ovary cell line. Galsulfase (glycosaminoglycan N -acetylgalactosamine 4-sulfatase, EC 3.1.6.12) is a lysosomal enzyme that catalyzes the cleavage of the sulfate ester from terminal N –acetylgalactosamine 4-sulfate residues of glycosaminoglycans (GAG), chondroitin 4-sulfate and dermatan sulfate.
