Mu opioid receptors (MOR) agonists exert strong anti-nociceptive activity but their ability to cause tolerance and physical dependence are serious issues of concern and limit their use. The activation of another branch of opioid receptors discovered lately, the opioid-related nociceptin receptor 1 (OPRL1) has recently shown the ability to enhance MOR agonist-induced analgesia while limiting tolerance and side effects.
New treatment options are needed for the prevention of relapse to alcohol use, the major problem in the treatment of alcohol dependence in humans. The neuropeptide relaxin-3/RXFP3 plays a relevant role in the motivation for the reward process and is considered a possible therapeutic target in addictive behaviors.
Research in rhesus monkeys has shown a gene therapy that enhanced activity in dopamine producing neurons in the brain was effective at stopping excessive alcohol consumption in previously addicted animals.
Amygdala Neurosciences Inc. has been awarded a $2.0 million NIH grant to support IND-enabling and early-stage development of its selective, reversible, orally bioavailable aldehyde dehydrogenase 2 (ALDH2) inhibitor ANS-858 to treat alcohol use disorder (AUD).
The U.S. FDA has issued a draft guidance for devices intended to address opioid use disorder (OUD), a problem with a massive public health footprint that has defied the efforts of public health programs. The draft guidance highlights some of the difficulties in executing pivotal studies for these devices, but the FDA’s July 27 press omits any mention of a 2018 innovation challenge for this category of devices, a programmatic effort that seems to have yielded little in the way of tangible results.
Cessation Therapeutics Inc. has obtained IND clearance from the FDA to initiate a first-in-human trial of CSX-1004 for the prevention of fentanyl overdose. The trial in healthy volunteers is expected to begin next month.
Researchers from Addex Therapeutics Ltd. have published preclinical data for the novel positive allosteric modulator of the metabotropic glutamate mGlu2 receptor, ADX-106772, being developed for the treatment of opioid use disorder (OUD).
Adamis Pharmaceuticals Corp.’s wholly owned subsidiary DMK Pharmaceuticals Corp. has been awarded a grant from the National Institute on Alcohol Abuse and Alcoholism (NIAAA) of the National Institutes of Health (NIH) to support the development of a novel bifunctional small molecule for the treatment of alcohol use disorder.
