The milestone is based on dosing the first patient in a Boston Pharmaceutical-sponsored phase 1/2 study of BOS-342 (formerly PRS-342), a 4-1BB/GPC3 immuno-oncology antibody-Anticalin fusion (Mabcalin) bispecific protein, which was discovered by Pieris and licensed to
The open-label phase 1/2 study is designed to evaluate the safety, tolerability, pharmacokinetics, and efficacy of BOS-342. The Phase 1 dose escalation portion of the study is expected to enroll adults with hepatocellular carcinoma (HCC) that progressed on at least one prior treatment and establish a recommended Phase 2 dose. If pursued, the Phase 2 portion of the study will evaluate efficacy, as measured by overall response rate.
The study is funded and conducted by
'We are delighted with
'Dosing of the first patient with BOS-342 represents an important milestone for the BOS-342 program and, more importantly, for patients with HCC, many of whom often do not achieve durable benefit from current available treatment regimens,' said
