Bio-Thera Solutions Announces First Patient Dosed in Australia for BAT6021, an ADCC-enhanced Monoclonal Antibody Targeting TIGIT for the Treatment of Solid Tumors

GUANGZHOU, China–(BUSINESS WIRE)–#AUSTRALIA–Bio-Thera Solutions, Ltd. (SH: 688177), a commercial-stage pharmaceutical company, today announced that dosing has begun in Phase 1 clinical study to evaluate the pharmacokinetics, safety, and preliminary anti-tumor activity of BAT6021, a monoclonal antibody with enhanced ADCC targeting TIGIT in cancer cells.

�BAT6021 is Bio-Thera’s third IO asset that has entered Phase 1 study in a month.” said Dr. Shengfeng Li, CEO, Bio-Thera Solutions. “We plan to explore combinations of BAT6021 with our other oncology assets to treat a broad range of cancers.” Dr. Shengfeng Li continued, “we are very pleased to see BAT6021 enter clinical study in Australia, as this is an important step for bringing this innovative and highly differentiated anti-TIGIT antibody to cancer patients.”

BAT6021 has demonstrated highly potent single-agent and combinatorial anti-tumor activity in vivo pharmacology studies. The Phase 1, multicenter, open-label, dose-escalation clinical trial of BAT6021 is designed to assess the safety and tolerability of BAT6021 as a single agent and in combination with BAT1308, a novel anti-PD-1 antibody in advanced solid tumor patients. Key objectives in the study include determining maximum tolerated dose and recommended phase 2 dose (RP2D), pharmacokinetics and preliminary anti-tumor activity in the monotherapy and combination therapy. Disease-specific expansion cohorts will be enrolled at the RP2D in Australia, China and other countries to further evaluate the safety and efficacy of BAT6021 in a series of malignancies.

Bio-Thera Solutions is developing several additional innovative oncology assets directed at important IO targets, including PD-1, OX40, CTLA-4, CD47, and IO bispecifics targeting synergistic targets like PD-L1/CD47.
