The multicenter, randomized, double-blinded trial tested doses of 25, 50, 100 and 200 micrograms compared with a placebo.

“We’re very confident based on the results that 100 micrograms is the right dose to bring into our phase three studies, as we didn’t see any more improvement with 200 micrograms but did see additional adverse effects,” Karlin said.

Professor David Nutt, director of the Neuropsychopharmacology Unit at Imperial College London’s division of brain sciences, who researches psychedelics, said in an email that the study results “are very exciting data in what can be a difficult to treat population (anxiety).”

“They expand the likely utility of psychedelic treatment beyond depression,” said Nutt, who was not involved in the research. “And again, as with the depression trials, a single dose produces enduring effects, probable due to its breaking down persistent negative thought processes.”

While it was not the study’s primary purpose, results did show that MM120 also improved signs of depression, Karlin said. “We saw rapid and robust improvement on depression symptoms in people — depression and anxiety have overlapping disease definitions.”
