Non-opioid IV-free procedural sedation and pain relief could aid in the battle against opioid abuse

San Diego, CA – March 27, 2018 — Imprimis Pharmaceuticals, Inc. (NASDAQ: IMMY), an ophthalmology- focused pharmaceutical company, today announced it has secured a patent covering the company’s innovative MKO (midazolam, ketamine, and ondansetron) Melt® compounded formulation from the US Patent and Trademark office. US Patent 9,918,993 B2 entitled “PHARMACEUTICAL COMPOSITIONS FOR ANESTHESIOLOGICAL APPLICATIONS” was issued on March 20, 2018.

Mark L. Baum, CEO of Imprimis, stated, “We are pleased to have been granted this patent which covers our MKO Melt® formulation and a variety of other versions of midazolam and ketamine combinations we intend to make available to address unmet patient needs. Since we first made the MKO Melt available in 2015, it has been dispensed as a compounded formulation over 70,000 times, used primarily prior to and during cataract surgery.” John Berdahl, MD, board-certified ophthalmologist and co-inventor of the MKO Melt, added, “We have completed more than 10,000 cataract surgeries using the MKO Melt and have had great success with it. We have found that it offers unique benefits to patients who may not be well suited for traditional IV sedation. I am pleased it is now protected by this newly issued patent, and potentially, other procedural sedation patent applications that remain pending.”

Imprimis believes that beyond cataract surgery, there are likely more than 100 million annual procedures in the US ranging from dental, obstetric and gynecological, medical imaging procedures (such as MRIs and CAT scans), vasectomies, colonoscopies, dermatological, plastics procedures, orthopedic, otolaryngological, podiatry, emergency room, urology, and psychiatric that may benefit from an IV-free and opioid-free formulation.

MKO Melt Clinical Studies

Imprimis’ MKO Melt compounded formulation is the subject of two IRB-approved clinical studies. The first is a prospective, three arm, randomized double blind investigator initiated study of 724 total patients undergoing cataract surgery. This study has been completed and the manuscript and accompanying data is being prepared for submission for peer-review. The second is a National Institutes of Health (NIH) funded prospective randomized double-blinded study that will follow patients receiving cataract surgery with either traditional IV anesthesia or oral anesthesia, evaluate their comfort ratings, then determine if their comfort correlates to the type of anesthesia they received. This study, which is expected to be completed in 2018, is being conducted by a major midwestern US healthcare system. A third study, related to the pharmacokinetics of the MKO Melt, is being planned for completion during 2018.
