Clinical Trial Summary

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.

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:

• Response will be assessed by a global response score integrating change in skin disease as measured by the modified severity-weighted assessment tool (mSWAT) score, change in lymph node size, change in visceral disease, and changes in peripheral blood Sézary cells by flow cytometry. CR/PR assignment requires confirmatory assessment in 4 weeks. Skin scores, clinical lymph node, liver and spleen exam, and Sézary cell count assessment will occur on Day 1 of each cycle. Contrasted CT scan of the neck, chest, abdomen and pelvis will be performed at screening for all patients. In patients with lymphadenopathy and/or organomegaly at screening, contrasted CT scans of the neck, chest, abdomen, and pelvis will occur at the end of every third cycle of therapy, within 1 week of cycle 8 completion, and every 6 months for one year after maximal response. All patients will have contrasted CT scans of the neck, chest, abdomen, and pelvis at the time of concern for disease progression in lymph nodes and/or viscera.TTR is the time of the first romidepsin dose to the time of documented objective response (PR/CR). DOR is the time from first objective response (PR or CR) until disease progression.

• TTP will be measured from the time of the first romidepsin dose until disease progression.

• Pruritus will be assessed monthly using a 100 mm visual analog scale. Quality of life will be assessed monthly by Functional Assessment of Cancer Therapy- General (FACT-G), Skindex-29, and ItchyQOL questionnaires.

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.

Eligibility

Inclusion Criteria:

1. Able to understand and voluntarily sign an informed consent form.

2. Age =18 years at the time of signing the informed consent form.

3. Able to adhere to the study visit schedule and other protocol requirements.

4. 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)

5. 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.

7. Laboratory test results within these ranges:

• Absolute neutrophil count =750/mm³

• Platelet count=75,000/mm³

• Total bilirubin = 2 x upper limit of normal (ULN)

• ULN and Aspartate Aminotransferase (ALT) (SGPT) = 3 x ULN.

• Creatinine < 2 mg/dL

8. 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
