4SC AG: Positive safety review of Phase Ib/II EMERGE study of domatinostat + avelumab in gastrointestinal cancer

• Safety Review Committee examined data from the second dose cohort and recommends EMERGE to continue with the third and final dose cohort
• Patient recruitment for the third dose cohort will start in January 2020

Planegg-Martinsried, Germany, 13 December 2019 - 4SC AG (4SC, FSE Prime Standard: VSC) today announced, that the Safety Review Committee consisting of clinical and drug safety experts evaluated the safety data from the second dose cohort and recommended continuation with the third and final dose cohort in the ongoing Phase Ib/II EMERGE study (ClinicalTrials.gov identifier: NCT03812796). Patient recruitment for the third dose cohort will begin in January 2020. The study is being conducted by Prof. David Cunningham, MD FRCP FMedSci, Head of the Gastrointestinal and Lymphoma Unit and Director of Clinical Research at The Royal Marsden NHS Foundation Trust (London, UK).

The multi-center, single-arm, open-label study initiated in January 2019, is a dose escalation study in the first part, conducted initially in up to 15 patients with microsatellite-stable gastrointestinal cancer. The study evaluates domatinostat in combination with the checkpoint inhibitor avelumab. The study is conducted in two parts, an initial part to evaluate the safety of domatinostat in combination with a checkpoint inhibitor and to determine a recommended Phase II dose, potentially followed by a second "expansion" part in order to obtain a larger data-set through the addition of more patients at the preferred dose.

About domatinostat

Domatinostat is an orally administered small molecule class I selective HDAC inhibitor. It strengthens the body's own anti-tumor immune response, influences the tumor and tumor microenvironment, making the tumor more visible to the immune system and facilitating the infiltration of immune cells into the tumor.

Domatinostat has been investigated in a Phase I study in 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 from which initial data was presented at ESMO 2019. 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 currently being conducted by Prof. David Cunningham at The Royal Marsden NHS Foundation Trust in London, UK.

4SC also plans to advance domatinostat into a number of other studies in combination with a checkpoint inhibitor, including in patients with advanced Merkel-cell carcinoma (MCC), in 2019 and 2020.
