Kelun-Biotech Advances TROP2-ADC Treatment for Lung Cancer
Kelun-Biotech's NDA Approval for TROP2-ADC Treatment
Kelun-Biotech has reached an important milestone with the acceptance of its new drug application (NDA) for sacituzumab tirumotecan (sac-TMT), also known as SKB264, by the National Medical Products Administration (NMPA). This application specifically addresses the treatment needs of adult patients suffering from epidermal growth factor receptor (EGFR)-mutant locally advanced or metastatic non-small cell lung cancer (NSCLC). These patients typically experience disease progression following the use of EGFR-tyrosine kinase inhibitor (TKI) therapy.
Details of the OptiTROP-Lung04 Study
The NDA acceptance is grounded on the promising results from the pivotal phase III OptiTROP-Lung04 trial, which was designed to explore the efficacy and safety of sac-TMT in comparison to standard treatments involving pemetrexed and platinum-based chemotherapy. In this randomized, multi-center study, sac-TMT monotherapy has shown a statistically significant improvement in progression-free survival (PFS) as assessed by a blinded independent review committee. Additionally, the safety profile of sac-TMT remains manageable, with no unforeseen safety signals reported.
NDA History and Future Potential
This marks the third NDA acceptance for sac-TMT by the NMPA. Earlier applications focusing on its use in triple-negative breast cancer and other NSCLC indications have also been accepted. Notably, the timeline for the latest NDA includes plans for priority review and expedited approval, reflecting the treatment's significance in oncology.
Innovative Mechanism of Action
Sac-TMT stands out as a novel human trophoblast cell-surface antigen 2 (TROP2) antibody-drug conjugate (ADC). It contains proprietary intellectual property rights that allow it to target various advanced solid tumors, including NSCLC and breast cancer among others. The unique design of sac-TMT features a new linker used to attach the active ingredient, a belotecan-derivative topoisomerase I inhibitor, which is effective in inducing cell cycle arrest and apoptosis in tumor cells.
Collaborations and Global Outreach
In a strategic move to enhance the drug's reach, Kelun-Biotech licensed exclusive rights to MSD (Merck & Co., Inc.) for the development and commercialization of sac-TMT outside of Greater China. This collaboration aims to leverage MSD's extensive market presence and expertise, expanding the potential impact of sac-TMT on a global scale.
Future Prospects for the Company
Dr. Micheal Ge, the CEO of Kelun-Biotech, expressed optimism regarding the future of sac-TMT in addressing unmet clinical needs. He emphasized the company’s commitment to original innovation and its resolve to improve global health outcomes through its advanced drug development initiatives. Kelun-Biotech is working hard to position itself as a key player in the oncology space.
