ABBV-319: A CD19-targeting glucocorticoid receptor modulator antibody-drug conjugate therapy for B-cell malignancies. (PubMed, Blood) - P1 | "ABBV-319 also showed durable anti-tumor activity across multiple B-cell lymphoma PDX models, including non-germinal center B-cell (GCB) DLBCL and relapsed lymphoma post R-CHOP treatment. Collectively, these data support the ongoing evaluation of ABBV-319 in Phase I clinical trial (NCT05512390)."

ABBV-319: A first-in-class Glucocorticoid Receptor Modulator (GRM) agonist ADC for the treatment of B-cell malignancies (AACR 2023) - P1 | "Given ADCC/ADCP is a highly effective mechanism in B-cell malignancies (e.g., rituximab, tafasitamab) the CD19 antibody was engineered to have increased FcγR binding via afucosylation, that retains its enhanced ADCC activity as a GRM drug conjugate. ABBV-319 was well tolerated in cynomolgus monkey studies with favorable drug-like properties and antibody-like pharmacokinetics, enabling a high mg/kg clinical starting dose. A first in-human Phase 1 clinical trial evaluating ABBV-319 in B-cell malignancies (DLBCL, FL, CLL) was recently initiated in late 2022 (clinicaltrials.gov, NCT05512390)."

Preclinical development of ABBV-319: a CD19-targeting glucocorticoid receptor modulator (GRM) agonist antibody-drug conjugate (ADC) for the treatment of B-cell malignancies (AACR 2023) - "Introduction: Glucocorticoids are key components of standard-of-care treatment regimens (e.g., R-CHOP, Hyper-CVAD) for several B-cell malignancies. ABBV-319 has potent anti-tumor activity from three distinct MoA and exhibits safety improvements compared to systemic glucocorticoids, supporting its recent progression into Phase I clinical trial."
