Phase I study of pucotenlimab (HX008), an anti-PD-1 antibody, for patients with advanced solid tumors.

ABSTRACT:

Background

Pucotenlimab is a humanized immunoglobulin G4 (IgG4) anti programmed cell death protein 1 (anti-PD-1) monoclonal antibody (mAb) with a S228P hinge mutation and an engineered Fc domain. Preclinical data suggests that pucotenlimab exerts antitumor effects. In this phase I study, which was prospectively registered on www.chinadrugtrials.org.cn (CTR20180125), the safety, maximum tolerated dose, preliminary antitumor activity, pharmacokinetics, and immunogenicity of pucotenlimab were evaluated in patients with advanced solid tumors.

Methods

Patients with advanced solid tumors refractory to standard therapies were recruited. In a 3+3 dose escalation study, 13 patients received pucotenlimab intravenously every 3 weeks (Q3W) until disease progression or unacceptable toxic
