Antibody-drug conjugates (ADCs)
?

Mablink Bioscience is a biotechnology company developing next-generation antibody-drug conjugates (ADCs) for cancer treatment. Its proprietary PSARLink technology involves linking antibodies to cytotoxic payloads via a unique hydrophilic linker structure. This "masking" approach enables the ADCs to remain stable in the plasma and stay longer in the body, allowing more time to target and kill tumor cells. Notably, PSARLink ADCs have demonstrated an improved therapeutic index of up to 10-fold in animal models compared to conventional ADCs, potentially offering a broader therapeutic window.

Mablink's lead candidate, MBK-103, is an ADC targeting the folate receptor alpha (FRα) overexpressed in several solid tumors. It consists of an Fc-attenuated humanized IgG1 antibody, the PSARLink linker, and the potent topoisomerase I inhibitor exatecan as the payload. preclinical studies revealed significant tumor growth inhibition across multiple FRα-positive mouse models at low doses of 1-3 mg/kg. Additionally, MBK-103 exhibited promising safety results in non-human primates, enabling a broad therapeutic window. Mablink plans to submit an IND for MBK-103 in the fourth quarter of 2023, following successful manufacturing process development.

In October 2023, Mablink entered an agreement to be acquired by Eli Lilly and Company, reflecting the potential of its existing pipeline and PSARLink technology for developing additional drug conjugates. The acquisition is subject to approval from the French Ministry of the Economy.
