Abstract


Objective: To characterize the pharmacokinetics (PK) and in vitro alcohol dissolution characteristics of extended-release (ER), injection-molded (IM) morphine tablets with abuse-deterrent (AD) features (morphine-ADER-IMT).

Design: In vivo, in vitro, and in silico studies were conducted. A randomized, two-cohort study evaluated the bioequivalence of morphine-ADER-IMT (60 mg) to morphine ER (60 mg; MS Contin®; Purdue Pharma LP, Stamford, CT) and characterized the effect of food on the PK profile of morphine-ADER-IMT. A three-treatment, three-period crossover study assessed the bioequivalence of morphine-ADERIMT (30 and 2 × 15 mg) to morphine ER (30 mg). Bioequivalence studies were performed in healthy male and female subjects (18-55 y of age) in the presence of naltrexone blockade. PK modeling was performed to assess steady-state bioequivalence for morphine-ADER-IMT 60 mg compared with morphine ER 60 mg. In vitro alcohol dissolution studies were performed with morphine-ADER-IMT (15 and 60 mg).

Results: Fifty-nine and 56 subjects completed the 60-mg bioequivalence/food effect study and 30-mg bioequivalence study, respectively. Bioequivalence of morphine-ADER-IMT 60, 30, and 2 × 15 mg and morphine ER was demonstrated to comparable doses of morphine ER. No clinically significant food effect was observed with morphine-ADER-IMT. Treatment-emergent adverse events were similar among all treatment groups. Steady-state modeling indicated bioequivalence between morphine-ADER-IMT 60 mg and morphine ER 60 mg when administered every 8 or 12 hours. No evidence of alcohol dose-dumping was observed with morphine-ADER-IMT.

Conclusions: Morphine-ADER-IMT, an ER morphine formulation with robust AD features, has a clinical PK profile that is well suited for patients with chronic pain.
