About Kinselby (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, and primarily affects the skin, but may ultimately involve lymph nodes, blood and visceral organs.  

Currently, CTCL is incurable 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 was conducted at more than 50 clinical centers in 11 European countries and Japan. It included 201 patients who suffer from advanced-stage cutaneous T-cell lymphoma (CTCL) that have achieved disease control with systemic therapy. The patients were randomized 1:1 to receive either resminostat or placebo. Patients who experienced disease progression – while being on placebo – were offered resminostat in an open label treatment arm.  

The primary goal of the study was to determine whether maintenance treatment with resminostat prolongs progression-free survival and other secondary objectives. Data demonstrating that resminostat met the primary endpoint of the RESMAIN study was published in May 2023.

About the concept of maintenance therapy  

The pivotal RESMAIN study is focused on patients with advanced-stage, incurable, cutaneous T-cell lymphoma (CTCL). Such patients suffer from painful and itchy skin lesions resulting in disfigurement and a severely impaired quality of life. Furthermore, lymph nodes, blood or visceral organs can be involved. The current therapeutic options rarely provide long-lasting responses or stabilization of disease for meaningful periods, with most patients progressing within a few months.  

Resminostat is being evaluated as maintenance treatment - a unique innovative treatment approach in CTCL (Stadler et al., 2021) - intended to prolong the period patients are stable and not progressing.
