About
This a multi-center, single arm, open-label, Phase I dose-finding and preliminary efficacy study of the combination of the histone deacetylase inhibitor romidepsin (Istodax®) in combination with doxorubicin HCl liposomal (Doxil®) for adult patients with relapsed or refractory cutaneous T-cell lymphoma after at least 2 lines of skin-directed therapy or one prior line of systemic therapy. Patients will be treated with Doxil 20mg/m2 on day 1 and romidepsin 8-14mg/m2 on days 1, 8 and 15, every 28 days, until 2 cycles beyond the best response, 8 cycles, disease progression or intolerability whichever comes first. Importantly, doxil is administered prior to romidepsin on day1 of each cycle. Patients will be followed until disease progression or death whichever comes first.
Full description
This a multi-center, single arm, open-label, Phase I dose-finding and preliminary efficacy study of the combination of the histone deacetylase inhibitor romidepsin (Istodax®) in combination with doxorubicin HCl liposomal (Doxil®) for adult patients with relapsed or refractory cutaneous T-cell lymphoma after at least one prior line of systemic therapy.
STUDY ENDPOINTS:
Primary:
MTD will be determined by standard "3+3" dose escalation of romidepsin with a fixed dose of doxorubicin HCl liposomal. Participants will be followed throughout therapy and all adverse events recorded, graded, and given likelihood of relevance to study therapies. Toxicity will be graded by the NCI Common Toxicity Criteria for Adverse Events (CTCAE) version 4.0.
Secondary:
Exploratory:
Skin lesions will be punch biopsied (two contiguous 5mm biopsies) prior to beginning therapy as standard care of care. Any leftover tissue will be collected for research with consent of patient. Optional single 5mm punch biopsies will be obtained on day 15 of Cycle 2 after infusion of romidepsin, and at disease relapse.

Inclusion criteria
Able to understand and voluntarily sign an informed consent form.
Age ≥18 years at the time of signing the informed consent form.
Able to adhere to the study visit schedule and other protocol requirements.
Biopsy-proven, measurable, Stage IB-IVB relapsed or refractory cutaneous T-cell lymphoma after 2 lines of skin-directed therapy or one prior line of systemic therapy (Note: extracorporeal photopheresis will be considered a systemic therapy for this study)
All cancer therapy, including radiation, hormonal therapy and surgery, must have been discontinued at least 4 weeks prior to treatment in this study. The only exceptions are participants with erythroderma who have been on corticosteroids for prolonged periods of time (>60 days) without change may continue use of either low dose systemic steroid (equivalent to <10 mg per day of prednisone) or low potency topical steroids are eligible for this study if the frequency and dosage steroids has not changed for 60 days prior to the study. These participants should continue on the same dose of systemic/topical steroid throughout the study period unless they achieve a complete response at which time steroids can be discontinued. Patients are allowed to continue any medications with known activity in T cell lymphomas at the pre-enrollment doses for conditions other than T cell lymphomas (ie, steroids for sarcoidosis) , as long as there is evidence of T cell lymphoma progression while patients were on these agents.
Eastern Cooperative Oncology Group (ECOG) performance status of ≤ 2 at study entry.
Laboratory test results within these ranges:
Disease free of prior malignancies for ≥ 5 years with exception of currently treated basal cell, squamous cell carcinoma of the skin, or carcinoma in situ of the cervix or breast. Patients with early stage of prostate cancer under clinical surveillance without therapy are eligible
Negative serum pregnancy test at the time of enrollment for females of childbearing potential.
For males and females of child-producing potential, use of effective contraceptive methods during the study to include 2 methods of contraception, one being a condom.
Life expectancy >90 days.
Exclusion criteria
Any serious medical condition, laboratory abnormality, or psychiatric illness that would prevent the subject from signing the informed consent form.
Pregnant or breast feeding females.
Any condition, including the presence of laboratory abnormalities, which places the subject at unacceptable risk if he/she were to participate in the study or confounds the ability to interpret data from the study.
Use of any other experimental drug or therapy within 28 days of baseline except topical therapy for mycosis fungoides which must be discontinued 14 days prior to initiation of study therapy.
Prior allogeneic hematopoietic cell transplant.
Prior solid organ transplant.
Cumulative anthracycline exposure greater than 300 mg/m2 doxorubicin equivalents.
Known active viral infection with human immunodeficiency virus (HIV), hepatitis B virus (HBV) or hepatitis C virus (HCV). Patients who are seropositive because of prior hepatitis B virus vaccination are eligible.
Central nervous system or meningeal involvement
Any known cardiac abnormalities including:
Patients taking drugs leading to significant QT prolongation and unable to stop drugs prior to treatment
Concomitant use of CYP3A4 inhibitors or inducers unless able to stop medication(s) prior to starting study therapies
