4SC AG ( http://www.4SC.com ) 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 ( http://www.4sc.com/product-pipeline/resminostat/ ) and domatinostat ( http://www.4sc.com/product-pipeline/4sc-202/ ).
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 48 employees as of 30 June 2021 and is listed on the Prime Standard of the Frankfurt Stock Exchange (FSE Prime Standard: VSC; ISIN: DE000A3E5C40).
Domatinostat is an orally administered small molecule class I selective HDAC inhibitor. It strengthens the body’s own anti-tumor immune response. Domatinostat modulates the tumor and tumor microenvironment making it more visible to the immune system, susceptible to concomitant checkpoint inhibition, and facilitating the infiltration of immune cells into the tumor (Bretz et al., 2019). 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 (Tresckow et al., 2019). Signs of single-agent anti-tumor efficacy were observed; with one complete remission and one partial responder. Besides its therapeutic potential as monotherapy, 4SC is focusing its development activities for domatinostat on 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 (Hassel et al., abstract # 5545) and at ASCO 2021 (Hassel et al., abstract # 9545).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. In addition, in a collaboration with the Netherlands Cancer Institute in Amsterdam, the DONIMI Study, a multicenter, investigator-sponsored phase Ib study, is conducted testing the combination of domatinostat, nivolumab and ipilimumab in high risk stage III melanoma in the neoadjuvant setting. To advance this development program, 4SC has also signed a drug supply agreement with Merck KGaA for avelumab (anti-PD-L1 antibody) to conduct two Phase II clinical trials of domatinostat in combination with avelumab in advanced-stage Merkel cell carcinoma (MCC) patients progressing on previous anti-PD-(L)1 monotherapy (MERKLIN 2) and in metastatic treatment-naïve patients (MERKLIN 1).
Avelumab Approved Indications
Avelumab (BAVENCIO®) is indicated in the US for the maintenance treatment of patients with locally advanced or metastatic urothelial carcinoma (UC) that has not progressed with first-line platinum-containing chemotherapy. BAVENCIO is also indicated for the treatment of patients with locally advanced or metastatic UC who have disease progression during or following platinum-containing chemotherapy, or have disease progression within 12 months of neoadjuvant or adjuvant treatment with platinum-containing chemotherapy.
Avelumab in combination with axitinib is approved in the US for the first-line treatment of patients with advanced renal cell carcinoma (RCC).
In the US, the FDA granted accelerated approval for BAVENCIO for the treatment of adults and pediatric patients 12 years and older with metastatic Merkel cell carcinoma (MCC). This indication is approved under accelerated approval based on tumor response rate and duration of response. Continued approval may be contingent upon verification and description of clinical benefit in confirmatory trials.
Avelumab Important Safety Information from the US FDA-Approved Label
The warnings and precautions for avelumab (BAVENCIO®) include immune-mediated adverse reactions (such as pneumonitis and hepatitis [ including fatal cases ] , colitis, endocrinopathies, nephritis, and other immune-mediated adverse reactions as a single agent or in combination with axitinib [ which can be severe and have included fatal cases ] ), infusion-related reactions, hepatotoxicity in combination with axitinib, major adverse cardiovascular events (MACE) in combination with axitinib [ which can be severe and have included fatal cases ] , and embryo-fetal toxicity.
Common adverse reactions (reported in at least 20% of patients) in patients treated with BAVENCIO® monotherapy include fatigue, musculoskeletal pain, diarrhea, nausea, infusion-related reaction peripheral edema, decreased appetite, urinary tract infection and rash. Common adverse reactions (reported in at least 20% of patients) in patients receiving BAVENCIO® in combination with axitinib include diarrhea, fatigue, hypertension, musculoskeletal pain, nausea, mucositis, palmar-plantar erythrodysesthesia, dysphonia, decreased appetite, hypothyroidism, rash, hepatotoxicity, cough, dyspnea, abdominal pain and headache. Grade 3-4 hematology laboratory value abnormalities reported in at least 10% of patients with Merkel cell carcinoma treated with BAVENCIO® monotherapy include lymphopenia; in patients receiving BAVENCIO® in combination with axitinib, grade 3-4 clinical chemistry abnormalities include blood triglyceride increased and lipase increased.
