Cancer treatment company Prescient Therapeutics (PTX) is progressing its PTX-100 drug to the dosing next level in its phase one trials of the product.
The company told shareholders today the drug, which is being tested to treat a basket of cancers with a specific type of mutation, will now be upped in dosage after the latest round of testing was proven to be safe.
Patients have now been tested with 500 mg/m² and 100 mg/m² doses of PTX-100. The measurement, milligrams per square metre, is standard in drug dosage and works out how much of a drug to deliver based on a patient’s body surface area.
On top of the already-tested doses proving safe, Prescient said two patients under the 500 mg/m² cohort have reported stable disease or better and are continuing their treatment. Particularly, one patient is stable while the other has achieved a partial response.
Now, Prescient will scale things up and test the drug in 2000 mg/m² doses.
Prescient CEO and Managing Director Steven Yatomi-Clarke said the company is pleased to progress this unique study to the next dose level, particularly in the era of COVID-19.
“We thank the patients involved and the dedication of the researcher teams for their work given the challenges and disruptions faced by everyone working in our healthcare system,” he said.
Overall, the PTX-100 study is set to test up to 24 patients to measure how Prescient’s drug moves around the body, what effect it has on the cancers, and how safe it is. The upcoming 2000 mg/m² dosing is the third and final planned dose.
Patients under the study will receive an injection of PTX-100 over five days every two weeks, for a total of eight weeks.
Following today’s news, Prescient shares are trading 12.07 higher at 6.5 cents each. The company has s $25.63 million market cap.
