Botanix announces positive trial data

Company News

Medical dermatology company Botanix Pharmaceuticals (ASX:BOT) has announced positive data from the first in-human study of its Permetrex skin drug delivery technology.

According to the company, the Permetrex formulation was found to have “minimal or weak irritancy potential” and no product-related adverse events.

“We are very pleased with the results from this study and what it means for the BTX-1503 acne program and the wider pipeline of opportunities that leverage the Permetrex drug delivery technology,” said Botanix executive director Matt Callahan.

“Permetrex showed very low potential to irritate the skin which means we can proceed with confidence into the next study for BTX-1503 including synthetic cannabidiol in the formulation,” he said, “as we already know, synthetic cannabidiol has been dosed to patients at 20-30 times higher dosages in other studies than what we will be using in our clinical studies.”

This study was conducted in the US under ethics approval and enrolled 28 healthy volunteers who received repeat doses of Permetrex, as well as positive and negative controls with established irritation profiles. Trial participants were treated daily over a 14 day period to study the extent of any potential skin irritation and adverse safety events that may arise. 

"Botanix separated the conduct of the safety and irritation studies, so that Permetrex drug delivery formulation was tested separately from the final BTX-1503 formulation, which includes the drug active known as synthetic cannabidiol," said the company. "Permetrex makes up the majority of the formulation of BTX-1503, which is on schedule to be tested in a further study in healthy volunteers and acne patients, commencing in the first half of 2017."

“The data from this Permetrex study also supports the broader product pipeline that Botanix is developing for a range of skin diseases, in addition to our lead product, BTX-1503,” added Mr Callahan.

“The ability to drive drugs more efficiently into the skin, without the risk of serious irritation and other safety concerns from the delivery technology, opens up a number of new opportunities for us across a wide range of diseases.”
