Egalet Human Abuse Potential Data at American Pain Society Annual Meeting Demonstrates Significantly Lower Intranasal Abuse Potential of ARYMO™ ER Compared to MS Contin®

WAYNE, Pa., May 12, 2016 /PRNewswire/ -- Egalet Corporation, a fully integrated specialty pharmaceutical company focused on developing, manufacturing and commercializing innovative treatments for pain and other conditions, presented data at the 35^th Annual American Pain Society annual meeting demonstrating that ARYMO™ ER (morphine sulfate) extended-release tablets, an abuse-deterrent, oral morphine product candidate, had significantly lower drug liking scores compared to MS Contin^® (morphine sulfate extended-release tablets) CII. The Category 2/3 intranasal human abuse potential (HAP) study showed no relevant food effect with ARYMO ER, while an in vitro dissolution study showed no evidence of alcohol dose dumping. Developed for the management of pain severe enough to require daily, around-the-clock, long-term opioid treatment and for which alternative treatment options are inadequate, ARYMO ER was created using Egalet's proprietary Guardian™ Technology. The U.S. Food and Drug Administration (FDA) accepted the new drug application (NDA) for ARYMO ER and it is currently under review. The FDA Prescription Drug User Fee Act (PDUFA) goal date for a decision on ARYMO ER is October 14, 2016.

Highlights of the data from the three posters include:

• A Category 2/3 clinical intranasal HAP study of 46 subjects comparing the pharmacokinetic (PK) profile and abuse potential of ARYMO ER and MS Contin demonstrated that:
  • A higher level of effort was initially required to physically manipulate ARYMO ER to prepare it for insufflation compared with the ease of crushing MS Contin into a fine powder;
  • 'Overall drug liking' was significantly reduced for ARYMO ER (51 on the 100-pt bipolar overall drug liking Visual Analog Scale [VAS]) compared to MS Contin (71; p < 0.0001) and was similar to placebo (50);
  •  The response to 'take drug again' was significantly lower for ARYMO ER (50 on the 100-pt bipolar take drug again VAS) compared to MS Contin (73; p < 0.0001) and was similar to placebo (50);
  • the Abuse Quotient (AQ: Cmax or maximum plasma concentration/Tmax or time to Cmax), a PK indicator of abuse potential, was much lower for ARYMO ER (2.3 – 9.2) compared to MS Contin (37.2)  
    
• In a clinical food effect study, ARYMO ER in the fed state was bioequivalent to the product dosed in a fasted state; thus, no clinically significant interaction with food was observed with ARYMO ER
  
• In an in vitro alcohol interaction study, there was no evidence of dose dumping of ARYMO ER in the presence of various concentrations of ethanol; in fact, the release of morphine from ARYMO ER was slower with increasing concentrations of alcohol

"The data support a strong, clinically relevant abuse-deterrent profile for ARYMO ER," said Jeffrey Dayno, MD, chief medical officer at Egalet.  "The PK data demonstrate no significant food effect so that ARYMO ER can be taken without regard to food. The data also show no evidence of alcohol dose dumping, an important safety aspect of the product.  These findings from our extensive abuse-deterrent development program support a robust profile for ARYMO ER based on both the pharmacokinetic and pharmacodynamic results from a Category 2/3 intranasal human abuse potential study."
