(“CTTQ”), has entered into an exclusive license and supply agreement with Cipla for Rolditamig Deuderuxtecan, also known as TQB2102, a potential best-in-class HER2 bispecific antibody-drug conjugate (“ADC”). Under this agreement, Cipla will receive exclusive rights to develop and commercialise TQB2102 in India, South Africa and 5 other emerging markets. Cipla will be responsible for local clinical development, regulatory activities, and commercialisation in the licensed territories, while CTTQ will continue to manufacture and supply TQB2102. TQB2102 is being evaluated across HER2-expressing cancers and has demonstrated encouraging clinical potential in HER2-low advanced breast cancer. The collaboration brings together SBP Group’s differentiated late-stage oncology asset and development and manufacturing capabilities with Cipla’s established regulatory, medical, market access and commercial presence across India, South Africa, and other emerging markets. The partnership is intended to accelerate local development and regulatory approvals, enabling patient access across licensed countries, subject to applicable approvals. Commenting on the partnership, Achin Gupta, Managing Director and Global Chief Executive Officer, Cipla said, “At Cipla, innovation is central to our mission of expanding access to therapies that address unmet patient needs. Breast cancer remains a significant healthcare challenge, and this agreement strengthens our oncology portfolio with a promising HER2-targeted antibody-drug conjugate. Through our partnership with SBP Group and CTTQ, we aim to accelerate development and, subject to regulatory approvals, expand access to this innovative treatment across licensed territories.” “Expanding global access to medicines developed by SBP Group is a central part of our strategy,” said Eric Tse, CEO, SBP Group. “TQB2102 has demonstrated encouraging clinical potential across different HER2-expressing breast cancer populations. Cipla’s scale, local expertise and commitment to patient access make it a strong partner to help bring this treatment to patients across India, South Africa and other emerging markets.” About Rolditamig Deuderuxtecan Rolditamig Deuderuxtecan, also known as TQB2102, is a next-generation HER2 dual-epitope bispecific ADC independently developed by SBP Group. It simultaneously binds to the ECD II and ECD IV domains of HER2 and incorporates a cleavable linker and topoisomerase I inhibitor payload. The differentiated design is intended to overcome limitations associated with conventional HER2 monoclonal antibodies or single-target ADCs. In particular, the dual-epitope binding mode may enhance receptor cross-linking and endocytosis efficiency, supporting potential differentiated advantages in the treatment of patients with HER2-low expression. Rolditamig deuderuxtecan has received three Breakthrough Therapy Designations from the Center for Drug Evaluation of China’s National Medical Products Administration. It is currently being evaluated for HER2-low, HER2-positive breast cancer, colorectal cancer, and biliary tract cancer across multiple treatment settings.
