Acura Pharmaceuticals Advances LTX-04 and its LIMITx™ Technology
The patented LIMITx technology works by neutralizing stomach acid with buffering ingredients as increasing numbers of tablets are swallowed and relies 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 results from Study 401 have allowed for a fuller understanding of the LIMITx Technology as a whole and changed the way we analyze the data such that we now believe the abuse deterrence of LIMITx may achieve up to a 65% reduction in peak blood levels," commented
Study 401 was a randomized, fasted, crossover design pharmacokinetic study testing Acura's LIMITx formulation LTX-04P3 in healthy adult subjects. A single dose of LTX-04P3 demonstrated a Cmax of 52% compared to the marketed comparator. Given that the single tablet Cmax for LTX-04P3 in Study 401 was consistent with the Cmax observed in Study 400 (55% for LTX-04S and 50% for LTX-04P compared to the marketed comparator) and the active ingredient in LTX-04P3 in acid media laboratory dissolution tests showed a 2.7x faster release in 5 minutes than the Study 400 formulations, the Company has concluded that the inhibited release at one tablet is due to excessive levels of buffering ingredients in the single tablet that is neutralizing the acidic gastric fluid and retarding the timely release of the active ingredient from that single tablet.
At the seven tablet dose, the Cmax of LTX-04P3 was 35% of the Cmax for the marketed comparator. The seven tablet LTX-04P3 dose, on a dose proportionality basis, demonstrated a 32% further reduction in Cmax when compared to the single tablet dose. Comparatively, in Study 400 there was an approximate 20% further reduction in Cmax for 8 tablets compared to a single tablet dose based on a dose proportionality analysis.
Study 401 enrolled 64 subjects with 27 completing the single tablet dose and 28 completing the seven tablet dose, divided into two subgroups. There were no severe adverse events in Study 401 and the doses were generally well tolerated.
