Active clinical trials for "Lymphoma, T-Cell"

The purpose of this study is to evaluate the efficacy and safety of High dose of Methotrexate combined with gemcitabine, pegaspargase and dexamethasone (GAD-M regimen) as first-line treatment in patients with de novo extranodal NK/T cell lymphoma.

T cell lymphoma is a heterogenic malignancy with poor outcome. Five-year PFS and OS of the patients recieved classic CHOP regimen(cyclophosphamide,vincristin,doxorubicin and predisone)is less than 30%.High dose intensive chemotherapy doesn't demonstrate better response. At present, there is no standardized treatment protocol for this kind of lymphoma. Between 1994 and 1998,the Scotland and Newcastle Lymphoma Group prospectively collected data on newly diagnosed patients with enteropathy associated T-cell lymphoma (EATL)in the Northern Region of England and Scotland,which is a rare and aggressive type of peripheral T-cell lymphoma.The novel regimen IVE/MTX (ifosfamide, vincristine, etoposide/methotrexate)-ASCT was piloted for patients eligible for intensive treatment,followed by auto-stem cell transplantation.Five-years PFS and OS were 52% and 60% respectively, significantly improved compared with the historical group treated with anthracycline-based chemotherapy. The encouraged results were extended to the peripherial T cell lymphoma-non specified(PTCL-nos). Past studies suggested pirarubicin was more active to the T cell lymphoma than doxorubicin in vitro based on its high concentration in tumor cells. Clinical data also presented equivalent even superior efficacy of pirarubicin with lower toxicity than doxorubicin. The aim of our study is to compare the response and survival rate of CTOP/ITE/MTX (cyclophosphamide, vincristin,pirarubicin and predisone/ ifosfamide, pirarubicin, etoposide/methotrexate) with those of CHOP regimen,looking forward to its superiority in efficacy and safety for the de novo young patients with T cell lymphoma.

The primary objective of this study is to evaluate the efficacy of Fludarabine, Adriamycin and Dexamethasone (FAD) as first line therapy in patients with Peripheral T-cell lymphomas (PTCL). 30 patients will be treated into this study.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Photodynamic therapy uses light and drugs that make cancer cells more sensitive to light to kill cancer cells. Photosensitizing drugs, such as methoxsalen, are absorbed by cancer cells and, when exposed to light, become active and kill the cancer cells. Combining chemotherapy with photodynamic therapy may be an effective treatment for cutaneous T-cell lymphoma. PURPOSE: Randomized phase II trial to study the effectiveness of combining different doses of bexarotene with photodynamic therapy in treating patients who have stage IB or stage IIA cutaneous T-cell lymphoma.

Extranodal natural killer/T-cell lymphoma, nasal type (NKTCL) is a highly aggressive peripheral T-cell lymphoma (PTCL). Patients with newly diagnosed stage IV and relapsed/refractory have poor prognosis. 5-year progression-free survival was reported only 55%. Chidamide is a selective histone deacetylase inhibitor which was approved by FDA in treating relapsed or refractory PTCL. In phase I and II studies of chidamide, patients with relapsed or refractory NKTCL achieved a higher overall remission. Patients who obtained complete or partial remission had much favourable duration of remission. Thus, the invesgator design this study to evaluate the role of maintenance treatment of chidamide for induction chemotherapy-responded newly-diagnosed advanced and relapsed/refractory NKTCL patients.

Cutaneous lymphomas are rare cancers of lymphocytes (white blood cells) that involve the skin. Mycosis Fungoides (MF) is the most common type of Cutaneous T-cell lymphoma (CTCL) that typically presents with red, scaly patches that often mimic eczema or chronic dermatitis. The incidence of MF is about 1/100,000. Skin lesions tend to appear before the diagnosis of CTCL is made by several years. Early skin lesions may look like any dermatitis, eczema, or psoriasis, leading to delays in the diagnosis. Inflammation secondary to bacterial infection is thought to contribute to the T-cell proliferation in this type of cutaneous T-cell lymphoma. Antibiotic use for other purposes has shown to reduce the inflammation and size of lesions in CTCL patients. There has been limited studies with the use of antibiotics as direct treatment for this cancer. Host immunity is important in decreasing cancer development and progression. Imiquimod is a molecule that stimulates host immunity to reduce the progression of CTCL. There is strong evidence of clinical efficacy such that the National Comprehensive Cancer Network (NCCN) guidelines recommend Imiquimod for CTCL. Imiquimod is available in generic form, making it unlikely to be registered specifically for CTCL, despite its efficacy. Additionally, imiquimod is considered a first line treatment according to National Comprehensive Cancer Network (NCCN) guidelines for the treatment of Mycosis Fungoides. There are currently no studies that have been published that address treating CTCL patients with a combined approach of 1) decreasing inflammation caused by bacterial with antibiotics, and 2) enhancing the host immune system to destroy cancer cells. Our theory is if we treat patient with 14days of antibiotics and 30 days of Imiquimod there will be significant reduction in skin lesions.

It is a multi-center, prospective, open-label, two-stage optimized design, single-arm, phase II clinical study to evaluate the efficacy and safety of GB226 for the treatment of relapsed and refractory peripheral T cell lymphoma (PTCL), and to evaluate the immunogenicity of GB226.

For patients with NK/T-cell lymphoma, plasma EBV-DNA has been found to be a prognostic factor, and those with positive plasma EBV-DNA at the end of treatments are more likely to suffer from disease relapse. Thus, this study aims to evaluate the role of maintenance with anti-PD-1 antibody.

To observe the safety, tolerability and clinical effects of Chidamide Combined With Etoposide in Relapsed or Refractory NK/T-cell Lymphoma.

It is a multi-center, prospective, open-label, two-stage optimized design, single-arm, phase II clinical study to evaluate the efficacy and safety of F520 for the treatment of relapsed and refractory peripheral T cell lymphoma (PTCL), and to evaluate the immunogenicity of F520.
