Mabwell secures Brazilian ANVISA GMP approval for denosumab biosimilar, enabling market entry in Latin America’s largest pharmaceutical economy

Executive summary: Mabwell’s wholly-owned subsidiary T-mab successfully passed a Brazilian GMP inspection by ANVISA for its denosumab injections, achieving PIC/S GMP certification as announced on August 9, 2026. This approval is a prerequisite for marketing denosumab biosimilars in Brazil, the largest pharmaceutical market in Latin America, and enables Mabwell to compete with branded biologics in osteoporosis and oncology indications.

Who is involved: Mabwell (688062.SH, 02493.HK), its subsidiary T-mab, and Brazil’s Health Regulatory Agency (ANVISA).

Likely next: Mabwell will proceed with ANVISA product registration for denosumab, followed by potential launch in Brazil and possible expansion to other LATAM markets recognizing PIC/S standards.

Mabwell’s subsidiary T-mab has passed a Brazilian Health Regulatory Agency (ANVISA) inspection for its denosumab injections, achieving PIC/S GMP certification. This approval validates the manufacturing quality of Mabwell’s biosimilar to Amgen’s Prolia/Xgeva, clearing a critical regulatory hurdle for commercialization in Brazil. The move supports Mabwell’s strategy to expand its oncology and bone health portfolio in emerging markets, leveraging its integrated biopharma production chain. No financial terms or launch timelines were disclosed in the announcement.
