Masimo Corp.’s Opioid Halo, an opioid overdose prevention and alert system, was granted de novo status by the U.S. FDA. The device detects opioid-induced respiratory depression, the primary cause of opioid deaths. The de novo authorizes the company to make Halo available over the counter and by prescription for use on individuals aged 15 and up.
Researchers at Indiana University Bloomington have developed allosteric modulators of the opioid receptor that were superior to the opioid antidote naloxone at blocking the effects of fentanyl in vitro. They presented their work in a session on “Progress towards more efficacious medicine: Antibiotics and antidotes” at the 2023 spring meeting of the American Chemical Society (ACS).
Free, no-prescription-required access to naloxone injectors and nasal sprays has reduced deaths from opioid overdoses by 11% in some communities, but they only work if someone with the reversal agent is available when a person overdoses. Many times, unfortunately, opioid users are alone when an overdose occurs. Resilient Lifescience Inc. hopes to save those lives, too. The company is developing a wearable patch that monitors vital signs and automatically administers naloxone when needed.
It’s not a done deal yet, but Teva Pharmaceutical Industries Ltd. has agreed in principle to pay up to $4.25 billion, plus about $100 million to Native American tribes, to end most of the lawsuits it’s facing across the U.S. over its opioid sales. The figure includes settlements the company already has made with some state and local governments, as well as the supply of up to $1.2 billion worth of Teva’s generic naloxone nasal spray.
A lengthy trial over two generic drug manufacturers’ alleged role in fueling the opioid epidemic in West Virginia came to an end this week when the U.S. affiliate of Teva Pharmaceuticals Ltd. and Allergan, now part of Abbvie Inc., agreed to a settlement totaling more than $161.5 million.
Kaléo Inc. agreed to pay $12.7 million to end whistleblower allegations that the Richmond, Va.-based company caused the submission of false claims for Evzio (naloxone hydrochloride), an injectable drug used to reverse opioid overdoses.
The third time proved the charm for Adamis Pharmaceuticals Corp.’s high-dose naloxone injection, Zimhi, which gained FDA approval for use in treating opioid overdose, nearly three years after the San Diego-based company first submitted an NDA.
Shares of San Diego-based Adamis Pharmaceuticals Corp. (NASDAQ:ADMP) fell 51% to close Monday at 62 cents after the FDA issued a complete response letter regarding its high-dose naloxone injection candidate, Zimhi, for the treatment of opioid overdose. The agency raised questions about chemistry, manufacturing and controls (CMC), but not the candidate's safety or efficacy, the company said.
