"We are very pleased to see OBI Pharma receive FDA clearance for OBI-992 (BSI-992)," said Hugh M. Davis, Ph.D., Chief Business & Development Officer, and President of Biosion USA, Inc. "OBI-992 demonstrated superiority over other TROP2 ADCs in pre-clinical studies. It is a solid validation of the unique advantages of Biosion’s SynTracer platform to identify fit-for-purpose antibodies for the development of novel ADC therapies. We are excited about this innovative treatment and making a meaningful difference for patients worldwide."

OBI Pharma plans to enroll patients with advanced solid tumors, including non-small cell lung cancer (NSCLC), small cell lung cancer (SCLC), and gastric cancer (GC), although several other cancers are also potential targets. OBI Pharma’s Chief Medical Officer, Wayne Saville, M.D. noted, "The clinical trial intends to evaluate the safety, pharmacokinetics, and preliminary efficacy of OBI-992, a novel anti-TROP2 ADC with best-in-class potential. We look forward to dosing the first patient in our Phase 1/2 clinical study of OBI-992, which is expected to begin in early 2024."

Heidi Wang, Ph.D., OBI Pharma’s Chief Executive Officer, added, "OBI-992 is a novel anti-TROP2 ADC designed and engineered by OBI Pharma. It demonstrates outstanding preclinical efficacy, favorable safety, and high stability in numerous in-vivo studies compared to other TROP2 ADCs. We are excited to commence the first-in-human clinical trial of OBI-992. OBI Pharma strives to advance our promising therapeutics to the clinic for cancer patients."

About OBI-992 (BSI-992)

OBI-992 (BSI-992) is a TROP2-targeted antibody-drug-conjugate (ADC) that carries a potent topoisomerase I inhibitor payload to kill solid tumors. TROP2 is highly expressed in a variety of solid tumors such as lung, breast, ovarian, and gastric cancer, rendering it an ideal target for cancer therapy. OBI-992 (BSI-992) uses a differentiated hydrophilic, enzyme-cleavable linker that is stable in circulation but releases the cytotoxic payload inside tumor cells. OBI-992 (BSI-992 demonstrates remarkable antitumor efficacy, improved pharmacokinetic characteristics, and a favorable safety profile in animal models. The anti-TROP-2 targeting antibody was discovered and developed by Biosion, OBI Pharma owns ex-China commercial rights for OBI-992 (BSI-992).
