PermaLink®

Stable Safe Superior

Stable conjugation is fundamental to ADC design and improving therapeutic index. The foundation of Iksuda’s ADCs is its proprietary conjugation chemistry PermaLink®, which is associated with industry-leading conjugation stability.

PermaLink® is a cysteine-specific, vinyl pyridine-based chemistry that demonstrates inherent conjugation stability and, unlike many other approaches to conjugation, Iksuda’s PermaLink® chemistry is not susceptible to drug de-conjugation.

As demonstrated in Preclinical in vivo experiments, PermaLink® based ADCs are associated with improved tolerability and overall tumour response. The enhanced stability profile of PermaLink® enables the safer use of ultra-potent toxins which, when conjugated to antibodies that are directed to well-selected targets, results in more efficacious ADCs.
