Avenue Therapeutics Announces Publication of Phase 3 Bunionectomy Study Results

Rhea-AI Summary

Avenue Therapeutics (NASDAQ: ATXI) announced the publication of Phase 3 study results for its IV tramadol, aimed at postoperative pain relief after bunionectomy. The study assessed 50 mg and 25 mg IV tramadol doses against a placebo. The 50 mg dose showed significant improvement in pain relief (p < 0.05) over placebo across primary and secondary endpoints, with a high completion rate (98.6%). While 25 mg was well-tolerated, it was deemed ineffective. The results support further development of IV tramadol 50 mg in the ongoing Phase 3 program.

Positive

• IV tramadol 50 mg demonstrated statistically significant pain relief compared to placebo (p < 0.05).
• High patient completion rate of 98.6% for IV tramadol 50 mg.
• Advancement of IV tramadol 50 mg into the next phase of clinical development.

Negative

• IV tramadol 25 mg was found ineffective for pain management in the study.

NEW YORK, July 21, 2020 (GLOBE NEWSWIRE) -- Avenue Therapeutics, Inc. (NASDAQ: ATXI) (“Avenue”), a company focused on the development of intravenous (“IV”) tramadol for the U.S. market, today announced that the results from its Phase 3 study of IV tramadol in patients undergoing bunionectomy have been published in the peer-reviewed journal, Pain and Therapy.

The objective of this Phase 3 study was to compare the analgesic benefit and tolerability of two doses of IV tramadol (50 mg and 25 mg) to placebo in adult patients undergoing bunionectomy, an orthopedic surgical model. Eligible patients were randomized (1:1:1 ratio) to IV tramadol 50 mg, 25 mg or placebo.  The primary endpoint was the summary of pain intensity differences (“SPID”) over 48 hours.  Key secondary endpoints included SPID over 24 hours, total consumption of rescue analgesia, and patient global assessment of efficacy.  Safety assessments included treatment emergent adverse events (“TEAEs”), clinical laboratory tests, vital signs, and electrocardiograms (“ECG”).  Assessment of the dose-response was an important objective of the study. The study established a clear dose response, with IV tramadol 50 mg demonstrating a statistically significant benefit (p < 0.05) over placebo for primary and all key secondary efficacy endpoints, whereas IV tramadol 25 mg demonstrated intermediate results between the 50 mg and placebo arms. IV tramadol 50 mg was well-tolerated.  The most common TEAEs were nausea and vomiting, and there were no meaningful differences among the treatments for vital signs, ECG, and laboratory assessments. The largest proportion of patients completed IV tramadol 50 mg (98.6%) compared to IV tramadol 25 mg (91.8%) and placebo (88.2%). The study concluded that IV tramadol 50 mg was effective and well-tolerated as a treatment for postoperative pain following bunionectomy surgery, while IV tramadol 25 mg, although well-tolerated, was judged to be an ineffective dose for the treatment of pain in this setting.

Based on the results of the study, IV tramadol 50 mg was further developed in Avenue’s Phase 3 program.
