MedPacto plans to evaluate the safety, tolerability, pharmacokinetics, and anticancer efficacy of single-agent Bexotertinib in the clinical trial and, based on interim analysis results, will assess safety and efficacy in a larger patient population. A MedPacto representative stated, "We initiated the domestic clinical trial with the intention of providing clinical opportunities to osteosarcoma patients in Korea who currently have no suitable treatment options," adding, "The trial will confirm the safety of single-agent Bexotertinib in osteosarcoma patients."

In August of last year, MedPacto received approval from the U.S. Food and Drug Administration (FDA) for Phase 1/2 clinical trials of single-agent Bexotertinib in osteosarcoma patients. Single-agent Bexotertinib has also been designated by the FDA as a drug for rare pediatric diseases and as a fast-track development item.

Osteosarcoma is a malignant tumor that arises from bone or bone-related cartilage and other osseous tissues, accounting for approximately 0.2% of all malignant tumors. Osteosarcoma primarily occurs in younger age groups, with about 60% of cases developing during childhood or adolescence. It is known that 25-50% of osteosarcoma patients experience metastasis to the lungs, which often leads to death.
