About
This study evaluates the safety and tolerability of the addition of immunostimulatory therapy consisting of focal radiation with or without the Toll-like receptor (TLR) agonist Poly ICLC in patients with cutaneous T-cell lymphoma (CTCL) receiving concurrent therapy with the histone deacetylase inhibitor (HDACI) Romidepsin.
Full description
Histone deacetylase inhibitors in epigenetic therapy are one of the most active anti-tumor agents in patients with relapsed and refractory CTCL despite their suppressive effects on T cell function, yet the overall response rate and response duration with these agents remains suboptimal. Immune stimulatory agents may be the ideal therapy to combine with HDACI. To date, no one has evaluated whether the abscopal effect of radiation with and without the additional immune stimulation of a TLR-3 agonist can augmented the efficacy of anti-tumor directed epigenetic therapy in mycosis fungoides (MF) patients. The investigators hypothesize that a combined modality immuno-chemotherapy may be highly effective in patients with advanced MF.
This is a phase I study. It involves two arms of patients (A and B) who will be treated following a standard 3+ 3 design. Patients on Arm A are the ones who are initiating HDACI therapy, and patients on Arm B are the ones with stable disease or partial response with HDACI treatment. Both groups receive HDACI, plus at level 1, focal lesional radiation; at level 2, radiation in combination with Poly ICLC. Each arm will be evaluated and escalated independently.

Inclusion criteria
Must have prior biopsy at any time point diagnostic for confirmed MF stage IIA-IVA, and must have failed at least one standard therapy (topical or systemic).
Must have a skin lesion of at minimum 2 cm, in a location amenable to radiation and a minimum of 2 additional measurable skin lesions distant from the radiation site.
Must be either initiating therapy with romidepsin (Arm A) or currently receiving romidepsin with documented stable disease (SD) or partial response (PR) (Arm B).
Patient may have had any prior topical or systemic therapy except for total electron beam irradiation. Patients must be a minimum of 2 weeks from topical therapy and 4 weeks from systemic therapies, phototherapy, or local radiation therapy before enrollment except for HDACI if they are in Arm B. Patients are allowed to take weak potency topical corticosteroids if patient has been on a stable dose for more than a month.
Eastern Cooperative Oncology Group (ECOG) performance status =< 2 (Karnofsky >70%)
Life expectancy of greater than 6 months
Patients must have normal organ and marrow function as defined below:
Age >=18 years
The effects of focal radiation and HDACI on the developing human fetus are unknown. For this reason and because agents as well as other therapeutic agents used in this trial are known to be tetragenic, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately.
Ability to understand and the willingness to sign a written informed consent document.
