About resminostat Resminostat is an orally administered class I, IIb and IV histone deacetylase (HDAC) inhibitor that potentially offers an approach to treating different kinds of cancer. Resminostat demonstrated that it is well tolerated and can inhibit tumor growth and proliferation, cause tumor regression, and strengthen the body’s immune response to cancer. Resminostat is currently being investigated in a pivotal study in cutaneous T-cell lymphoma (CTCL) as maintenance treatment by 4SC in Europe and by Yakult Honsha in Japan. About cutaneous T-cell lymphoma (CTCL) CTCL is a rare disease with approximately 5,000 patients being newly diagnosed in Europe each year. The disease arises from malignant transformation of T-cells, a specialized subgroup of immune cells, primarily affects the skin, but may ultimately involve lymph nodes, blood and visceral organs. Currently, CTCL is not curable and treatment options for advanced-stage CTCL are limited. Although patients respond to the available treatment options, the duration of response is often short-lived and declines as the severity of the disease increases. The key therapeutic challenge in advanced-stage CTCL is therefore to make remissions more durable by halting disease progression and improving patient’s quality of life. About the RESMAIN study – resminostat for maintenance treatment of CTCL The pivotal RESMAIN study is being conducted at more than 50 clinical centers in 11 European countries and Japan. It will include more than 190 patients who suffer from advanced-stage cutaneous T-cell lymphoma (CTCL) that have achieved disease control with systemic therapy.
