Seven and Eight Biopharmaceuticals Inc. Announces the First Patient Treated in a Phase 2 Clinical Trial of the TLR 7/8 dual agonist BDB001 in anti-PD-1 / anti-PD-L1 Refractory Solid Tumors

EDISON, N.J.–(BUSINESS WIRE)–Seven and Eight Biopharmaceuticals Inc., a clinical stage biotechnology company focused on developing proprietary novel immuno-oncology therapies to activate the immune system against cancer, announced today that the first patient has been treated in a Phase 2 clinical trial evaluating BDB001 in advanced solid tumors at The University of Texas MD Anderson Cancer Center in Houston, TX.

BDB001 is an intravenously administered Toll-Like Receptor 7 and 8 (TLR 7/8) dual agonist specifically designed to enhance immune activation against cancer. BDB001 has shown to be well tolerated as monotherapy and in combination with an anti-PD-1 mAb, with responses seen in multiple advanced solid tumor types (SITC, 2020¹; ASCO, 2021²).

BDB001-201 (NCT04819373) is an open-label, multi-arm Phase 2 clinical trial evaluating the efficacy, safety and tolerability of BDB001 in patients with advanced solid tumors that have progressed on anti-PD-1 or anti-PD-L1 mAb treatment.

“There is significant unmet need for effective treatment options for patients with anti-PD-1 / anti-PD-L1 refractory tumors,” said Dr. Robert H.I. Andtbacka, Chief Medical Officer, Seven and Eight Biopharma. “In our BDB001 Phase 1 clinical trial there was evidence of response in these tumors. We are excited to further explore the role of BDB001 in anti-PD-1 / anti-PD-L1 refractory tumors in a Phase 2 setting.”

“As an intravenously administered TLR 7/8 agonist, BDB001 has the potential to become a cornerstone of cancer immunotherapy. This Phase 2 program is an important milestone in our mission at Seven and Eight Biopharma, to develop novel treatments for cancer that expand immuno-oncology beyond PD-1, PD-L1, and CTLA-4,” said Dr. Walter Lau, Chief Executive Officer, Seven and Eight Biopharma.
