The ADC ABBV-400 comprises the c-Met–targeting antibody telisotuzumab conjugated to a potent topoisomerase 1 inhibitor payload. ABBV-400 showed promising preliminary efficacy, with molecular and radiographic responses in pts with advanced solid tumors with heterogeneous genomic profiles, including pts with high TMB and KRAS mutations.

METamp occurred more frequently in responders; but Teliso-V activity wasn’t restricted to these pts: most responders weren’t METamplified. Specific genomic alts beyond MET may influence clinical response. The current analysis demonstrated numeric differences between pts with identified drivers who did or didn’t respond to Teliso-V.

These results highlight the potential of MYTX-011 for treating a broader range of patients with NSCLC with c-MET expression than other c-MET-targeting ADCs. A first-in-human study is ongoing to determine the safety, tolerability, and preliminary efficacy of MYTX-011 in patients with NSCLC (NCT05652868).

Teliso-V was associated with durable responses in c-Met protein-overexpressing non-squamous EGFR-wildtype NSCLC, especially in those with high c-Met. AEs were generally manageable.

Of great note, there are currently nine c-Met-targeting ADCs being examined in different phases of clinical studies as well as eight preclinical studies for treating various solid tumors. The purpose of this study is to present a broad overview of clinical- and preclinical-stage c-Met-targeting ADCs.

The resulting biparatopic anti-c-MET ADCs were comparably active on c-MET expressing tumor cell lines as REGN5093 exatecan DAR6 ADC. Structural molecular modeling of paratope combinations for preferential inter-target binding combined with protein engineering for manufacturability yielded deep insights into the capabilities of rational and library approaches. The methodologies of in silico hydrophobicity identification and sequence optimization could serve as a blueprint for rapid development of optimal biparatopic ADCs targeting further tumor-associated antigens in the future.

Introduction: Telisotuzumab vedotin (Teliso-V) is a first-in-class antibodydrug conjugate that delivers a cytotoxic payload directly to tumor cells with MET protein (or c-Met) OE... MET OE was detected in 25% of samples, most of which were negative for METamp and MET mutations. A subpopulation of METamp patients did not have MET OE. NSCLC with MET OE was associated with worse prognosis compared with NSCLC with no MET OE in the context of standard-of-care treatment.
