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.
Protocol Summary Constitutive STAT3 activity is implicated in many malignancies including Cutaneous T Cell Lymphoma. It is also essential for Th17 differentiation, a subset of CD4 effector T cell, implicated in chronic inflammatory conditions and possibly CTCL. HDAC inhibitors have shown activity in CTCL but their exact mechanism of action is not known. It is known that HDAC inhibitors regulate STAT3 transcriptional activity and hence can potentially be active in CTCL through modulation of the STAT3 pathway. The hypothesis is that Th17 cytokines contribute to the initiation of cancer by creating a pro-inflammatory microenvironment that predisposes cells to neoplastic transformation. To probe this, the investigators will compare the differences in cytokine production and gene expression in the skin resident T cells from patients with benign dermatoses and CTCL as well as in the blood/circulating lymphocytes of healthy donors and Sezary syndrome (SS). The investigators will also investigate whether HDAC inhibitors have a direct impact on the number of Th17 cells, the cytokine production by these cells and phosphorylated STAT3 protein in CTCL with subsequent treatment cycles. The objectives of this study are 1. Observe the epigenetic, transcriptional and phenotypic changes that take place in T cell during malignant transformation 2. Understand the mechanism of action of HDAC inhibitors in CTCL. Methods: Skin biopsy specimens from cutaneous T cell lymphoma (CTCL) patients and benign skin conditions namely eczema, dermatitis and psoriasis will be obtained through a standard punch biopsy procedure from the skin lesion. Additionally, 15 ml of peripheral blood from CTCL patients who have Sezary syndrome (SS) and from patients with benign skin condition will be collected. CTCL patients, who are starting treatment with HDAC Inhibitors namely Vorinostat and Romidepsin, will have a total of 3 skin biopsies and/or blood draws. The first procedure would be before starting treatment with either of these HDAC inhibitors. Two more skin biopsies and/or blood draws will be performed after first and second cycle of treatment. Levels of Th17 cytokines, IL-17, IL -22 and pSTAT3 protein will be determined by IHC staining in the skin and cytokine levels in the blood will be assayed by sandwich ELISA method.The investigators will also assay the mRNA levels of the transcription factors of the different T effector cells by qPCR.
CTCL is a rare form of lymphoma of the skin. While early stages are usually confined to the skin, later stages may spread to blood, lymph nodes and other organs. At this point, patients usually require systemic chemo. This study will investigate the effect of everolimus as treatment for recurrent or refractory CTCL. Participation in this study will last as long as the study doctor believes disease has not gotten worse, and patients continue to tolerate the study medication for a maximum of 1 year. Once off the treatment, patients will be followed for two years.
The goal of this study is to identify genetic changes associated with the initiation, progression, and treatment response of response of cutaneous and hematologic disorders using recently developed high-throughput sequencing technologies. The improved understanding of the genetic changes associated with cutaneous and hematologic disorders may lead to improved diagnostic, prognostic and therapeutic options for these disorders.
Background: - Cutaneous T-cell lymphoma (CTCL) is a rare, slow-growing form of skin cancer. The cancer cells are found in red, scaly patches that may sometimes itch. - Early-stage CTCL is usually treated with topical therapies, which may lose effectiveness over time and have adverse effects, such as risk of secondary skin cancers and difficulty of use. - Romidepsin is an experimental drug that, given through a vein, has improved CTCL in some patients with later stages of the disease. - A topical ointment form of romidepsin may be helpful in treating early-stage CTCL. Objectives: - To determine the highest tolerated dose of topical romidepsin that can be given to patients with early-stage CTCL. - To evaluate the effectiveness of topical romidepsin in patients with early-stage CTCL. - To determine how the body handles topical romidepsin. Eligibility: -Patients 18 of age and older with early-stage CTCL. Design: - Study Part 1: Successive groups of 3 patients are treated with increasingly higher concentrations of topical romidepsin until the highest tolerated dose is found. - Study Part II: The highest tolerated dose, as determined in Part I, is applied to larger areas of skin in another group of patients. - All study participants apply the study medicine to their skin three times a day for 4 weeks. - During treatment, participants are monitored at weeks 2 and 4 with a history and physical examination, blood tests, electrocardiogram, skin biopsies and photographs of the skin. - After stopping treatment, participants return to the clinic at weeks 6 and 8 for blood tests and to see how the study medication is affecting the body.
The purpose of this study is to determine if vorinostat combined with low-dose total skin electron beam therapy (TSEBT) offers superior clinical benefit (efficacy & safety) over low-dose TSEBT alone in participants with mycosis fungoides (MF) Treatment in this study is TSEBT +/- vorinostat, with participants stratified by MF stage.
The purpose of this study is to define the mechanisms that underlie the refractory pruritus (itch) in Cutaneous T-Cell Lymphoma (CTCL).
This study will assess the safety, efficacy and pharmacokinetics of oral LBH589 in Japanese adult patients with refractory cutaneous T-Cell Lymphoma and adult T-cell leukemia/lymphoma. LBH589 is administered orally once a day for three days per week.
This study evaluated the safety and efficacy of LBH589B in adult participants with refractory/resistant Cutaneous T-Cell Lymphoma and prior Histone Deacetylase (HDAC) inhibitor therapy.
