Conditions: T Cell Lymphoma
Keywords: relapsed or refractory T cell lymphoma
Allocation: NA | Intervention model: SINGLE_GROUP
Enrollment: 12
Healthy volunteers: yes

Brief summary:
This study will be a pilot study of sorafenib 400mg PO twice daily in refractory T-cell lymphomas including peripheral T-cell lymphoma (PTCL), angioimmunoblastic lymphadenopathy (AILD), cutaneous T cell lymphoma (CTCL), anaplastic large cell lymphoma (ALCL) and other transformed T-cell lymphomas with the primary objective of studying the biological effects of the multikinase inhibitor, sorafenib.

Detailed description:
Primary objectives:

• To study the biological effects of sorafenib 400mg BID on the mitogen-activated protein kinase (MAPK) pathway, specifically the inhibition of extracellular signal-regulated kinases (ERK) phosphorylation, and to correlate with clinical activity in patients with T-cell lymphoma.

Secondary objectives:

* To observe the clinical activity of sorafenib 400mg BID by determining response rate, and progression free survival in patients with T-cell lymphoma. Duration of response and duration of stable disease will also be measured.
* To determine the tolerability of sorafenib in patients with T-cell lymphoma.

Exploratory objectives:

* To observe the effects of sorafenib on T-cell subsets (CD4/CD8 ratio, and Tregs), and the effects of sorafenib on the monocytoid population.
* To observe the effects of sorafenib on the serum cytokine profile.
* To observe the effects of sorafenib on the T-cell receptor pathway, i.e. Lck, ZAP-70, and Syk.
* To observe changes in lymph node or skin morphology including tumor cell infiltrate, vasculature, and the tumor microenvironment in patients treated with sorafenib by performing serial biopsies of lymph nodes or skin.

Arms:
arm 1: Sorafenib, 400 mg PO twice daily

Interventions: intervention 1: Sorafenib
Intervention descriptions: intervention 1: Intrapatient dose reduction to 400 mg once daily and then 400 mg every other day will be allowed depending on the type and severity of toxicity encountered provided that criteria for patient withdrawal from study treatment have not been met.
