Dren Bio

In November 2022, LLS made an equity investment in Dren Bio to "Support Clinical Development of the DR-01 Program for Rare Leukemia & Lymphoma Indications Including Large Granular Lymphocyte Leukemia (LGLL) and Cytotoxic Lymphomas."

Dren Bio is a clinical-stage biopharmaceutical company focused on developing therapeutic antibodies for the treatment of cancer, autoimmune and other serious diseases. Dren Bio’s pipeline encompasses two distinct programs, the first focusing on the engineering of antibodies with enhanced antibody-dependent cellular cytotoxicity (ADCC) capabilities and the second revolving around its proprietary Targeted Myeloid Engager and Phagocytosis Platform.

DR-01 is a novel antibody targeting CD94 which is known to be upregulated on LGLL cells. DR-01 functions through depletion of target cells via ADCC by means of fratricide, a method in which the same cell type induces ADCC on each other. A Phase 1/2 trial is ongoing to assess the safety and efficacy of DR-01 in previously treated LGLL patients and cytotoxic lymphomas (NCT05475925).

DR-0201 is a first-in-class bispecific antibody capable of engaging tissue-resident and trafficking myeloid cells to induce deep B cell depletion via targeted phagocytosis. DR-0201 has demonstrated a favorable preclinical safety profile in multiple non-human primate studies with no cytokine release syndrome or neurotoxicity. DR-0201 is currently being evaluated in a Phase 1 study in B-NHL patients (NCT06392477).
