4SC AG: Poster presentations at ESMO Congress 2019
Planegg-Martinsried, Germany, 23 September 2019 – 4SC AG (4SC, FSE Prime Standard: VSC) today announced that two posters on clinical studies combining domatinostat and anti-PD-(L)1 checkpoint inhibitor will be presented at the European Society of Medical Oncology (ESMO) Congress being held on 27 September to 1 October 2019 in Barcelona, Spain. The posters will be available on 4SC’s website after the presentation.

– Press release ends –
4SC AG is a clinical-stage biopharmaceutical company developing small-molecule drugs that can target key indications in cancer with high unmet medical needs. 4SC’s pipeline is protected by a comprehensive portfolio of patents and currently comprises two drug candidates in clinical development: resminostat and domatinostat.
4SC aims to generate future growth and enhance its enterprise value by entering into partnerships with pharmaceutical and biotech companies and/or the eventual marketing and sales of approved drugs in select territories by 4SC itself.
4SC is headquartered in Planegg-Martinsried near Munich, Germany. The Company had 47 employees as of 30 June 2019 and is listed on the Prime Standard of the Frankfurt Stock Exchange (FSE Prime Standard: VSC; ISIN: DE000A14KL72).
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 facilitates 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. 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 number of studies in combination with a checkpoint inhibitor, including in patients with advanced Merkel-cell carcinoma (MCC).
About the SENSITIZE study – Domatinostat (4SC-202) + pembrolizumab for treatment of melanoma
The SENSITIZE Phase Ib/II study (ClinicalTrials.gov identifier: NCT03278665) was opened for recruitment from September 2017 and is conducted at 6 certified skin cancer centers in Germany. It will enroll 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, 3 cohorts will be treated at 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 part of the study.
The primary goal of the study is to determine the safety and tolerability of domatinostat in combination with pembrolizumab and key secondary endpoints aim to assess the anti-tumor activity of the combination treatment. Additionally, the study will investigate changes in key immunological biomarkers to better understand how domatinostat renders patients more susceptible to treatment with checkpoint inhibitors. 4SC plans to present top-line data from the first part of the study at ESMO in 2019.
About the EMERGE study – Domatinostat (4SC-202) + avelumab for treatment of gastrointestinal cancer
The investigator-sponsored Phase II study EMERGE (ClinicalTrials.gov identifier: NCT03812796) was opened for recruitment in January 2019 and is conducted by Prof. David Cunningham from The Royal Marsden NHS Foundation Trust (London, UK).
The multi-center, single-arm, open-label study examines domatinostat plus checkpoint inhibitor avelumab in up to 70 patients with advanced gastrointestinal cancer – precisely microsatellite-stable esophago-gastric and colorectal (MSS-GI) cancer – who are refractory to previous chemotherapy treatment. So far, checkpoint inhibitors alone have not shown clinical activity in this patient population. In the first part of the study, 3 cohorts will be treated at different dose levels of domatinostat in combination with avelumab. In the second part, additional patients will be treated with the recommended dosing regimen defined in the first part of the study.
The study is intended to establish the safety of combining domatinostat with avelumab as well as to generate proof-of-concept clinical data in this patient population. 4SC anticipates top-line data from the first part of the study to be available in Q1 2020.
