PALATINE, Ill., May 18, 2017 (GLOBE NEWSWIRE) -- Acura Pharmaceuticals, Inc. (NASDAQ:ACUR), a specialty pharmaceutical company innovating abuse deterrent drugs, today announced that the Company has completed enrollment and initiated dosing in a second Phase 1 human pharmacokinetic trial of LTX-04, its lead development candidate utilizing Acura’s novel LIMITx™ technology.  The patented LIMITx technology works by neutralizing stomach acid as increasing numbers of tablets are swallowed and relying on stomach acid to play a role in the release and subsequent systemic absorption of the active ingredient from micro-particles contained in the tablets.  The Company expects dosing to complete by the end of May with topline results announced in June.

Study AP-LTX-401 (Study 401) is a randomized, fasted, crossover design testing Acura’s new formulation designated LTX-04P3 in healthy adult subjects.  In laboratory dissolution tests LTX-04P3 released drug faster with one tablet but also demonstrated better abuse deterrence with multiple tablets than the Company’s initial formulations.

Study 401 enrolled 60 subjects who will be randomly assigned to one of two cohorts.  Cohort 1 subjects are taking one LTX-04P3 tablet versus a marketed hydromorphone reference product with the objective to establish efficacious blood levels of the active ingredient and preferably bioequivalence.  Cohort 2 subjects will be further assigned to two subgroups.  Subgroup A subjects are taking 7 tablets of LTX-04P3 and the marketed hydromorphone reference product with the objective to demonstrate a reduction in peak blood levels of the active ingredient with LTX-04P3.  Subgroup B subjects are being dosed in an undisclosed, exploratory protocol.

About Acura Pharmaceuticals
Acura Pharmaceuticals is a specialty pharmaceutical company engaged in the research, development and commercialization of product candidates intended to address medication abuse and misuse, utilizing its proprietary LIMITX™, AVERSION® and IMPEDE® Technologies. LIMITX contains ingredients that are intended to reduce or limit the rate or extent of opioid release when multiple tablets are ingested. AVERSION contains polymers that cause the drug to gel when dissolved; it also contains compounds that irritate the nasal passages if the product is snorted.  IMPEDE is designed to disrupt the processing of pseudoephedrine from tablets into methamphetamine.

OXAYDO® (oxycodone HCl immediate-release tablets) which incorporates the AVERSION Technology, is FDA approved and marketed in the U.S. by our partner Egalet Corporation. 

NEXAFED® and NEXAFED® Sinus, which are pseudoephedrine containing products that utilize the IMPEDE Technology, are marketed in the U.S. by our partner MainPointe Pharmaceuticals.
