Planegg-Martinsried (pta009/11.01.2023/07:30 UTC+1)

Planegg-Martinsried, Germany, 11 January 2023 – 4SC AG (4SC, FSE Prime Standard: VSC) today announced that its pre-authorisation eligibility request to the European Medicines Agency (EMA) for resminostat in cutaneous T cell lymphoma had been accepted. During its meeting in December 2022 the CHMP agreed, on the basis of the documentation provided, that resminostat was eligible for submission of an application for a Union Marketing Authorisation according to the centralized procedure as detailed in Regulation (EC) No 726/2004.

Dr. Jason Loveridge, CEO of 4SC AG commented; "This is another positive step in getting resminostat to market in the EU for patients with CTCL.

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 200 patients who suffer from advanced-stage cutaneous T-cell lymphoma (CTCL) that have achieved disease control with systemic therapy. The patients are randomized 1:1 to receive either resminostat or placebo. Patients who experience disease progression – while being on placebo – will be offered resminostat in an open label treatment arm. 

The primary goal of the study is to determine whether maintenance treatment with resminostat prolongs progression-free survival and the key secondary objective is to prolong the time to symptom worsening (itching). A comprehensive biomarker program is also included in the study to ensure vital knowledge about the biological background of resminostat treatment in CTCL. 

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 several 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. Furthermore, recent preclinical data suggests that resminostat has the potential to alleviate the itching in CTCL patients, thereby additionally improving their quality of life.
