Research summary

Lomvastomig is a bispecific antibody targeting PD-1 and TIM-3 designed to reverse T-cell exhaustion and enhance antitumor immunity. Preclinical studies demonstrated potent antitumor activity, supporting advancement into clinical development. The Phase I study showed an acceptable safety profile, evidence of pharmacodynamic activity, and preliminary antitumor responses in patients with advanced solid tumors.

Key outcome of the study

Dual PD-1 and TIM-3 blockade enhanced antitumor activity in preclinical models and supported clinical development of lomvastomig. Clinical evaluation demonstrated pharmacodynamic activity consistent with immune activation and checkpoint inhibition.
