Drug information of Romidepsin
Romidepsin is used to treat T-cell lymphoma affecting the skin (cutaneous T-cell lymphoma, or peripheral T-cell lymphoma).
Romidepsin is given after at least one other cancer treatment did not work or has stopped working.
Mechanism of effect
Romidepsin is a prodrug, where it becomes active once taken up into the cell. The active metabolite has a free thiol group, which interacts with zinc ions in the active site of class 1 and 2 HDAC enzymes, resulting in inhibition of its enzymatic activity.
Romidepsin exhibited linear pharmacokinetics at standard doses.
Volume of distribution
Highly protein bound in plasma (92%-94%)
Romidepsin undergoes extensive hepatic metabolism in vitro primarily by CYP3A4 with minor contribution from CYP3A5, CYP1A1, CYP2B6 and CYP2C19.
Approximately 3 hours
Cutaneous T-cell lymphoma: Treatment of cutaneous T-cell lymphoma (CTCL) in adult patients who have received at least one prior systemic therapy.
Peripheral T-cell lymphoma: Treatment of peripheral T-cell lymphoma (PTCL) in adult patients who have received at least one prior therapy.
Cutaneous T-cell lymphoma: IV: 14 mg/m2 days 1, 8, and 15 of a 28-day treatment cycle; repeat cycle as long as benefit continues and treatment is tolerated.Peripheral T-cell lymphoma: IV: 14 mg/m2 days 1, 8, and 15 of a 28-day treatment cycle; repeat cycle as long as benefit continues and treatment is tolerated.

- Coadministration with other drugs that prolong QT interval (eg, sotalol, dofetilide, erythromycin) may increase risk for serious arrhythmias
- Binds to estrogen and may reduce effectiveness of oral contraceptives
QT prolongation; potassium and magnesium should be within normal limits before administration
Monitor hematologic parameters; interrupt/discontinue treatment if thrombocytopenia, leukopenia, or anemia becomes severe
Serious and sometimes fatal infections reported with 30 days after treatment including pneumonia, sepsis, and viral reactivation (eg, Epstein Barr, hepatitis B viruses); risk may be greater in patients with a history of monoclonal antibodies treatment directed against lymphocyte antigens and in patients with disease involvement of the bone marrow
Avoid during pregnancy, no adequate trials exist; based on MOA, likely to cause fetal harm
Points of recommendation
Tell your doctor if you have ever had:
- heart problems, heart rhythm disorder;
- long QT syndrome(in you or a family member);
- kidney disease;
- liver disease(especially hepatitis B);
- an electrolyte imbalance (such as high or low levels of potassium or magnesium in your blood); or
Based on its mechanism of action and findings from animal studies, may cause embryo-fetal harm when administered to a pregnant woman
