Femtogenix, a UK based biotechnology company developing the next generation of DNA-interactive Antibody Drug Conjugate (ADC) payloads, announced data demonstrating the potent efficacy and favorable toxicity profile of a reduced potency analog from its Pyridinobenzodiazepine (PDD) ADC payload platform in solid tumor models.

The presented data demonstrated that Femtogenix’s reduced potency payload has a favorable toxicity profile in rats, potent in vivo efficacy (MED < 1 mg/kg), and improved tolerability (MTD of 40 mg/kg) in solid tumor models when conjugated to antibodies. Its toxicity profile and the wide therapeutic window are coupled with the ability to increase the drug-antibody ratio (DAR) beyond the traditional limit of two, for increased conjugation to antibodies.

The data is being presented at AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics, Boston, USA.

As per a recent market research report by Roots Analysis, in the ADCs clinical pipeline, Auristatin has emerged as the most frequently used payload. Other prominent types of payloads are maytansinoid and PBD, which are part of 20% and 11% of the drugs, respectively.
