6:31AM Nektar Therapeutics announces top-line Phase III results from naloxegol pivotal trials in patients with opioid-induced constipation (NKTR) 8.15 : Co announced positive top-line results from two Phase III trials and one safety extension trial in patients with non-cancer related pain and opioid-induced constipation (OIC). These Phase III KODIAC trials evaluated the safety and efficacy of naloxegol, an oral peripherally-acting, mu-opioid receptor antagonist for the treatment of OIC, a common side effect of prescription opioids. Under the design of both trials, statistical significance for the primary endpoint would be achieved if at least one of the two naloxegol doses had a p-value <0.025 compared with placebo. Analysis of the data indicates that in KODIAC-04 both naloxegol doses (12.5 mg and 25 mg) demonstrated statistically significant results for the primary endpoint. P-values were 0.015 and 0.001 respectively. In KODIAC-05, the 25 mg dose demonstrated a statistically significant result for the primary endpoint but the 12.5 mg dose did not. P-values were 0.202 for 12.5 mg and 0.021 for 25 mg. The analyses also showed no clinically relevant imbalances in serious adverse events (SAEs), including externally adjudicated major cardiovascular events, across the three treatment arms in KODIAC-04, -05 and -07. The most common adverse events (AEs) in the naloxegol treatment arms in both trials were abdominal pain, diarrhea and nausea.
