atai Life Sciences Announces Positive Initial Results for Phase 1 Trial of KUR-101, an Oral Formulation of Mitragynine for OUD
– Initial results showed that single ascending oral dosing of KUR-101 produces dose-dependent analgesia (pain relief) with effects on respiration comparable to that of placebo.
– Topline results, including Part 2 comparing a single dose of KUR-101 to a single dose of oxycodone or placebo, are expected by the end of 2022.
– KUR-101 is an oral formulation of deuterated mitragynine, the major active alkaloid of the kratom plant, under development for the treatment of opioid use disorder (OUD).
– Nearly every 7 minutes, someone dies of an opioid-related overdose. Approximately 3 million people in the U.S. are diagnosed with OUD, and relapse occurs in up to 75% of patients.
NEW YORK and BERLIN, Oct. 12, 2022 (GLOBE NEWSWIRE) -- atai Life Sciences N.V. (Nasdaq: ATAI) (“atai”) announced today positive initial results for their Phase 1 clinical trial of KUR-101. KUR-101 is an oral formulation of deuterated mitragynine, the major active alkaloid of the kratom plant, under development for the treatment of opioid use disorder (OUD).
Initial results indicate that KUR-101 is safe and generally well-tolerated. Results also showed a dose-proportional pharmacokinetic (PK) profile that was unaffected by food. In the single ascending oral dose portion of the trial, no severe or serious adverse events were reported, with most treatment-related adverse events being mild. Changes in respiratory rate following treatment with KUR-101 were comparable to that of placebo-treated patients for the doses tested and comparable across doses.
“Exacerbated by the stresses of the pandemic, according to the CDC, the U.S. saw an approximate 30% increase in drug overdose deaths in 2020 and nearly 75% of those deaths involved opioids,” said Florian Brand, CEO of atai. “There are currently only three FDA-approved therapeutics for OUD; they produce side effects and about 75% of patients undergoing OUD therapy experience relapse within one year of treatment. New alternatives could improve the treatment landscape of addiction.”
According to Fortune Business Insights, the global OUD market is projected to grow from $2.68 billion in 2021 to $4.81 billion in 2028. The jump is driven partially by the surge in people suffering from opioid relapses and overdoses amid the pandemic.
The pharmacological therapies currently approved for OUD, buprenorphine, methadone, and naltrexone, carry several challenges, including limited efficacy for many patients, inconvenient treatment regimens, and access barriers due to inherent risks of abuse.
Compared with current options, KUR-101 is an atypical opioid receptor modulator with unique pharmacology that may make it safer for chronic use. The deuteration of mitragynine improves the PK and overall safety profile of KUR-101 while reducing dosing requirements. Topline results, including Part 2 of the trial comparing a single dose of KUR-101 to a single dose of oxycodone or placebo, are expected by the end of 2022.
“We’re pleased with the results of our initial Phase 1 findings of KUR-101,” said Dr. Chad Beyer, CEO of Kures, a subsidiary of atai Life Sciences leading the KUR-101 program. “These findings increase our confidence in KUR-101 as a potential treatment for patients battling addiction, experiencing pain, and debilitating mental health disorders.”

About Kures Therapeutics
Kures is a spinout from Columbia University and is developing KUR-101 for the treatment of OUD and acute pain. KUR-101 is a deuterated derivative of mitragynine, the major alkaloid in kratom that is a relatively low-potency mu-opioid receptor, or MOR, agonist. KUR-101 is a semi-synthetically produced drug substance designed to improve the safety profile and potential effectiveness of mitragynine. In results from our preclinical studies carried out to date, KUR-101 has shown dose-dependent analgesic effects without inducing significant respiratory depression at therapeutic doses in animal models.
