Indications

Romidepsin for injection is indicated for the treatment of cutaneous T-cell lymphoma (CTCL) in adult patients who have received at least one prior systemic therapy. Romidepsin for injection is a histone deacetylase (HDAC) inhibitor indicated for the treatment of cutaneous T-cell lymphoma (CTCL) in adult patients who have received at least one prior systemic therapy ( 1 ).

Contraindications

None. None ( 4 ).

Warnings and precautions

Myelosuppression: romidepsin can cause thrombocytopenia, leukopenia (neutropenia and lymphopenia), and anemia; monitor blood counts during treatment with romidepsin; interrupt and/or modify the dose as necessary ( 5.1 ).
Infections: Fatal and serious infections. Reactivation of DNA viruses (Epstein Barr and hepatitis B). Consider monitoring and prophylaxis in patients with evidence of prior hepatitis B ( 5.2 ).
Electrocardiographic (ECG) changes: Consider cardiovascular monitoring in patients with congenital long QT syndrome, a history of significant cardiovascular disease, and patients taking medicinal products that lead to significant QT prolongation. Ensure that potassium and magnesium are within the normal range before administration of romidepsin ( 5.3 ).
Tumor lysis syndrome: Patients with advanced stage disease and/or high tumor burden are at greater risk and should be closely monitored and appropriate precautions taken ( 5.4 ).
Embryo-fetal toxicity: Can cause fetal harm. Advise females of reproductive potential and males with female partners of reproductive potential of potential risk to a fetus and to use effective contraception ( 5.5 , 8.1 , 8.3 ).

5.1 Myelosuppression Treatment with Romidepsin can cause thrombocytopenia, leukopenia (neutropenia and lymphopenia), and anemia. Monitor blood counts regularly during treatment with romidepsin and modify the dose as necessary [see Dosage and Administration ( 2.2 ) and Adverse Reactions ( 6.1 )].

5.2Infections Fatal

and serious infections have been reported in clinical trials of romidepsin, including pneumonia, sepsis, and viral reactivation, including reactivation of Epstein Barr and hepatitis B viruses. These infections can occur during and following treatment. The risk of life-threatening infections may be greater in patients with a history of prior treatment with monoclonal antibodies directed against lymphocyte antigens and in patients with disease involvement of the bone marrow [see Adverse Reactions ( 6.1 )] .

6.1Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The data in the WARNINGS AND PRECAUTIONS reflect exposure to romidepsin in four clinical trials involving 363 patients with T-cell lymphoma, including 185 patients with CTCL.

Romidepsin was administered as a single agent at a dosage of 14 mg/m 2 on days 1, 8, and 15 of a 28-day cycle. Among 363 patients who received romidepsin, 21% were exposed for 6 months or longer and 13% were exposed for greater than one year. Cutaneous T-Cell Lymphoma The safety of romidepsin was evaluated in 185 patients with CTCL in 2 single arm clinical studies in which patients received a dosage of 14 mg/m 2 on days 1, 8, and 15 of a 28-day cycle.

Treatment continued as long as the patient benefitted from and tolerated the drug. The mean duration of treatment in these studies was 5.6 months (range: <1 to 83.4 months). Common Adverse Reactions Table 2 summarizes the most frequent adverse reactions (>20%) regardless of causality using the National Cancer Institute-Common Terminology Criteria for Adverse Events (NCI-CTCAE, Version 3.0). Due to methodological differences between the studies, the AE data are presented separately for Study 1 and Study 2.

Adverse reactions are ranked by their incidence in Study 1. Laboratory abnormalities commonly reported (>20%) as adverse reactions are included in Table 2 . Table 2.

Serious adverse reactions reported in >2% of patients in Study 1 were sepsis and pyrexia (3%). In Study 2, serious adverse reactions in >2% of patients were fatigue (7%), supraventricular arrhythmia, central line infection, neutropenia (6%), hypotension, hyperuricemia, edema (5%), ventricular arrhythmia, thrombocytopenia, nausea, leukopenia, dehydration, pyrexia, aspartate aminotransferase increased, sepsis, catheter related infection, hypophosphatemia and dyspnea (4%).

There were eight deaths not due to disease progression. In Study 1, there were two deaths: one due to cardiopulmonary failure and one due to acute renal failure. There were six deaths in Study 2: four due to infection and one each due to myocardial ischemia and acute respiratory distress syndrome. Discontinuations Discontinuation due to an adverse event occurred in 21% of patients in Study 1 and 11% in Study 2. Discontinuations occurring in at least 2% of patients in either study included infection, fatigue, dyspnea, QT prolongation, and hypomagnesemia.

Other Clinical Trials Experience The following common adverse reactions have been reported following administration of romidepsin as a single agent in 178 patients with peripheral T-cell lymphoma, for which romidepsin is not indicated or recommended. The most common adverse reactions (≥30%) included nausea (63%), fatigue (61%), thrombocytopenia (49%), vomiting (39%), neutropenia (39%), pyrexia (38%), diarrhea (36%) and anemia (35%).

Other common (≥10%) clinically significant adverse reactions included dysgeusia (22%), headache (20%), cough (19%), dyspnea (15%), abdominal pain (13%) and stomatitis (10%). Grade 3 and higher adverse reactions in ≥10% were hematologic toxicities (including thrombocytopenia, neutropenia, leukopenia and anemia) and fatigue.
