About the Company:

Dren Bio (the “Company”) is a privately held, pre-clinical stage biopharmaceutical company focused on developing therapeutic antibodies for the treatment of cancer, autoimmune and other serious diseases. The Company’s management team and scientific advisors have profound expertise covering the discovery and development of engineered antibodies designed to selectively target and deplete pathological cells. Dren Bio’s pipeline is currently comprised of two distinct programs. The first program surrounds DR-01, the Company’s lead product candidate, which induces antibody-mediated killing of a cell type that is responsible for a multitude of hematologic malignancies and plays a key role in various autoimmune diseases. The Company’s second program is a proprietary antibody-based technology platform, its Targeted Myeloid Engager, which utilizes a novel mechanism of action to selectively engage myeloid cells for the targeted depletion of diseased cells and disease-inducing agents, as well as to induce immunostimulation.

The candidate will work with a cross-functional team of scientists (immunologists, cell biologists, biochemists, and protein engineers) to advance research stage programs into early clinical development. The candidate will be expected to perform essential ex vivo and in vivo studies to not only assess efficacy of our novel therapeutic agents but to elucidate their impact on macrophage and dendritic cell functions in the tumor microenvironment. Importantly, the successful candidate will be provided necessary training, support, and opportunities to grow into and lead a therapeutic program or project sub-teams, and mentor other researchers.

Role and Responsibilities:
  • Work collaboratively with other researchers to advance various therapeutic antibodies in different cancer types

  • Design, conduct, and interpret high quality ex vivo studies (e.g. ADCC, ADCP, cytokine profiling, gene expression profiling) and in vivo studies (e.g. syngeneic, xenograft, and/or humanized mouse models of cancer) to evaluate efficacy and mechanism of action (MOA) of Dren Bio’s novel therapeutic agents

  • Specific tasks include animal or human tissue processing, multi-color flow cytometry for immuno-phenotyping, cytokine profiling by MSD or Luminex, ADCC or ADCP assays using Incucyte live-cell imaging and flow cytometry, IHC/IF and confocal microscopy, DNA/RNA extraction for gene expression studies, various biochemical techniques (IP, western blot, IHC, and IF)
