DGAP-News: 4SC AG: First patient enrolled in 3rd dose cohort of Phase Ib/II study SENSITIZE

First patient enrolled in 3^rd dose cohort of Phase Ib/II study SENSITIZE

First data from study of domatinostat (4SC-202) + pembrolizumab in melanoma expected in H1 2019
 

Planegg-Martinsried, Germany, 30 January 2019 - 4SC AG (4SC, FSE Prime Standard: VSC) today announced the enrollment of the first patient in the third dose cohort of the ongoing Phase Ib/II study SENSITIZE.

The SENSITIZE study (ClinicalTrials.gov identifier: NCT03278665) is enrolling up to 40 patients suffering from unresectable advanced-stage cutaneous melanoma who are refractory or non-responding to prior treatment with anti-PD-1 antibodies (checkpoint inhibitors).

In the first part of the study, three patient cohorts will be treated at three different dose levels of domatinostat in combination with pembrolizumab. In the second part, additional patients will be treated with the recommended dosing regimen defined in the first dose-finding part of the study. 4SC anticipates first data to be available in H1 2019.

Jason Loveridge, Ph.D., CEO of 4SC: "Enrolling the first patient in the third dose cohort of the SENSITIZE study again is a significant milestone for 4SC and the study is continuing steadily. We are convinced that the combination of domatinostat with checkpoint inhibitors is the best route to most rapidly progress domatinostat towards market approval. With this, as well as the investigator-sponsored Phase II study EMERGE in advanced gastrointestinal cancer, we continue to build momentum and execute on our plan, which is intended to lead to the initiation of a potentially pivotal trial in 2019."

About domatinostat (4SC-202)

Domatinostat is an orally administered small molecule Class I selective HDAC inhibitor with a unique mode of action that was designed to strengthen the body's own anti-tumor immune response. Domatinostat also influences the tumor microenvironment facilitating infiltration of immune cells into the tumor and making it more visible to the immune system.

Domatinostat has been investigated in a Phase I study with 24 heavily pretreated patients with several types of advanced hematologic cancers and was well tolerated. Positive signs of anti-tumor efficacy were also observed; with one complete remission (28 months) and one partial responder (8 months).

In addition to its therapeutic potential in cancer monotherapy, 4SC is evaluating domatinostat's capacity as a partner in combination therapies, specifically in the immuno-oncology area. In this respect, 4SC initiated a Phase Ib/II study of domatinostat in combination with the anti-PD-1 checkpoint inhibitor pembrolizumab in patients with advanced-stage melanoma. A second Phase II study of domatinostat in combination with the anti-PD-L1 checkpoint inhibitor avelumab in patients with advanced-stage microsatellite-stable gastrointestinal cancer is conducted by Prof. David Cunningham of The Royal Marsden NHS Foundation Trust (London, UK).

As soon as results from the aforementioned trials will be available, 4SC plans to advance domatinostat into a potentially pivotal study in combination with a checkpoint inhibitor in PD-(L)1 refractory patients with advanced Merkel-cell carcinoma (MCC).
