CMXTwenty recently completed its Phase 1 maximum tolerated dose human clinical study for the intravenous version of its CMX-020 drug in Australia. The company established a subsidiary there because the Australian government subsidizes medicine development if early trials show promising results, and its regulatory system can be more efficient.

“They have a diversified regulatory system; they have over 50 committees that can approve studies,” said Lane Brostrom, chief executive officer of CMXTwenty. “What that means is we can conduct clinical studies in Australia and then submit them to the FDA.”

So far, maximum tolerated dose studies have been promising, matching the efficacy of remifentanil, a potent opioid used in surgeries.

“We can match this remifentanil at a very high dose and we don’t see any adverse events,” Brostrom said. “We don’t even see a drug feel at that level.” Read the full story here.
