About Us

Company Overview

Prescient Therapeutics (ASX:PTX) are focused on developing novel, personalised therapies for a range of cancers.

Prescient’s universal CAR-T and targeted therapies are both personalised medicine approaches which seek to improve patient outcomes, whilst also new tools for clinicians in combating cancer.

Prescient has a broad pipeline of personalised cancer treatments, comprising CAR-T and targeted therapies, for a range of different cancers. Prescient has licensed technologies from and in collaboration with world-leading cancer centers in the US and Australia.

Prescient Therapeutics is working to rapidly expand the application of universal CAR-T therapies, capable of addressing all cancers, including solid tumours. We believe it’s about targets and tools.  

OmniCAR, a universal CAR-T platform employing technology licensed from UPenn, the pioneer and world leader in CAR-T, as well as Oxford University, will allow unprecedented control and flexibility over current generation CAR-T approaches. It combines the cancer-killing capabilities of a T-cell with the control and pharmacology of a drug.

Further to this, Prescient is working with leading CAR-T innovators to develop other improved CAR-T approaches.
