Scopus BioPharma Inc. is a clinical-stage biopharmaceutical company. The Company is focused on the development of its immuno-oncology programs. The Company’s Duet Platform relies on an immuno-oncology with a suite of bifunctional oligonucleotides that activate antigen-presenting cells (APCs) within the tumor microenvironment, while alleviating tumor immunosuppression to jump-start T cell-mediated immune responses. The Duet Platform is comprised of three bifunctional oligonucleotides that consists of a toll-like receptor 9 (TLR9) agonist linked with a signal transducer and activator of transcription 3 (STAT3) inhibitor, which include CpG-STAT3siRNA (DUET-01), CpG-STAT3ASO (DUET-02) and CpG-STAT3decoy (DUET-03). The Company is developing DUET-01 for the treatment of relapsed or refractory B-cell non-Hodgkin lymphoma. Its pipeline also includes MRI-1867, which is a cannabinoid receptor mediating compound for the treatment of systemic sclerosis.
