PK/PD data, Journal: Pharmacokinetics and Pharmacodynamics of TAK-164 Antibody Drug Conjugate Coadministered with Unconjugated Antibody. (Pubmed Central) - Oct 15, 2022 Rather, the cellular potency of DGN549 was matched with the single-cell uptake of TAK-164 making its IC close to its equilibrium binding affinity (K), and as such, coadministration dilutes total DGN549 in cells below the maximum cytotoxic concentration, thereby offsetting an increased number of targeted cells with decreased ability to kill each cell. These results provide new insights on matching payload potency to ADC delivery to help identify when increasing tumor penetration is beneficial for improving ADC efficacy and demonstrate how mechanistic simulations can be leveraged to design clinically effective ADCs.

PK/PD data, Journal: Quantifying ADC bystander payload penetration with cellular resolution using pharmacodynamic mapping. (Pubmed Central) - Oct 14, 2021 The penetration distance is similar to model predictions, where the lipophilicity results in moderate tissue penetration, thereby balancing improved tissue penetration with sufficient cellular uptake to avoid significant washout. These results aid in mechanistic understanding of the interplay between antigen heterogeneity, bystander effects, and heterogeneous delivery of ADCs in the tumor microenvironment to design clinically effective therapeutics.

Immune modulation following combination of TAK-164 with checkpoint inhibitors (Virtual Meeting II: E-Posters) - May 16, 2020 - Abstract #AACRII2020AACR-II_641; We performed immunophenotyping studies which revealed broad immunomodulation of lymphoid and myeloid cells by TAK-164 and combination regimens. Collectively these data support further interrogation of immune checkpoint inhibition in combination with TAK-164.

Journal: Synthesis of Highly Potent N-10 Amino-Linked DNA-Alkylating Indolinobenzodiazepine Antibody-Drug Conjugates (ADCs). (Pubmed Central) - Aug 16, 2019 Here, we present an alternative strategy for the IGNs, linking through a carbamate at the readily available N-10 amine present in the monoimine containing dimer. As a result, we have designed a series of N-10 linked IGN ADCs with a wide range of in vitro potency and tolerability, which may allow us to better match an IGN with a particular target based on the potential dosing needs.
