Recent Institutional Trials:
-
NALOX-202 (Phase III): A multi-center, randomized, double-blind, placebo-controlled trial enrolled 620 patients with OIC secondary to opioid therapy for non-cancer pain. Results published in The Lancet Gastroenterology (2022) indicated a statistically significant increase in spontaneous bowel movements (SBMs) at week 12 (mean difference: 3.2 SBMs/week, p<0.001).
-
NALOX-203 (Open-label safety study): Evaluated long-term safety over 52 weeks in 300 patients. No new safety signals identified; adverse events were mostly mild and gastrointestinal.
Regulatory Progress
- FDA Submission: The drug received a Complete Response Letter (CRL) in 2021, prompting further safety and efficacy data submission.
- EMA & MEE: Applications are under review, with Priority Review designations granted in certain markets due to unmet needs.
