> Resminostat reduces the expression of IL-31 – a messenger molecule which is associated with itching in patients with cutaneous T-cell lymphoma (CTCL)

> Resminostat therefore has the potential to alleviate one of the major disease burdens in affected patients

4SC AG (4SC, FSE Prime Standard: VSC) is currently investigating resminostat as maintenance therapy in the pivotal RESMAIN study in advanced-stage cutaneous T-cell lymphoma (CTCL) and this new preclinical data provides a better understanding of the molecular basis of resminostat’s anti-itching potential in patients with CTCL.

Itching in CTCL

CTCL is a blood cancer that arises from the malignant transformation of T cells – a specialized immune cell – where patients suffer from disfigurement and severe itching. To date, the underlying molecular mechanism of itching in CTCL has not been well understood and established anti-itching drugs such as anti-histamines have proven ineffective in CTCL patients.

Resminostat down-regulates itching-associated molecule in CTCL cell line

“From historical data we know that the messenger molecule IL-31 is produced by malignant T-cell populations in CTCL and high levels of IL-31 correlate with itching. It has also been established that in comparison to other treatment options, inhibitors of histone deacetylases (HDAC) can more effectively reduce itching in these patients,” explained Roland Baumgartner, Ph.D., Chief Scientific Officer of 4SC.

“Resminostat is an HDAC inhibitor that reactivates silenced genes in cancer cells and downregulates excessively active genomic areas. We performed a genome-wide analysis of a CTCL cell line before and after addition of resminostat and found that the expression of IL-31 was significantly reduced after treatment with resminostat. These new data provide an important addition to our understanding of how resminostat can alleviate itching in these patients, and in addition, given that time to symptom worsening is one of the major endpoints in our RESMAIN study, these data support our clinical development plans to advance resminostat to market authorization and to offer a new and effective treatment option to CTCL patients and physicians.”

Resminostat is orally administered and potentially offers a novel approach for the treatment of a wide variety of cancers, both as monotherapy and in combination therapy with other anti-cancer drugs. Resminostat inhibits tumor growth and proliferation, causes tumor regression, and strengthens the body’s immune response to cancer.

Resminostat has been shown to be well tolerated in several clinical trials. Resminostat is currently being investigated in a Phase II pivotal study in cutaneous T-cell lymphoma (CTCL) by 4SC. A Phase II study in biliary tract cancer is planned by 4SC’s development partner Yakult Honsha in Japan. Amongst others, resminostat has previously been investigated in biliary tract or pancreatic cancer and hepatocellular carcinoma (HCC).


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, halting disease progression, improving quality of life and prolonging progression free and overall survival.


About the RESMAIN study – Resminostat for maintenance treatment of CTCL

The RESMAIN pivotal study is open for recruitment since November 2016 and is being conducted at more than 50 clinical centers in 11 European countries. It will include 150 patients who suffer from advanced-stage cutaneous T-cell lymphoma (CTCL) and 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 and CTCL is acquired. 4SC anticipates top-line data to be available in 2019.
