Ketorolac Applied by Continuous IV Infusion for Treatment of Moderately Severe Postoperative Pain Following Bunionectomy
Study Details
Study Description
Brief Summary
This clinical study is a randomized, double-blind, double-dummy, parallel group, multi-center, active and placebo-controlled trial evaluating the analgesic efficacy and safety of NTM-001 in subjects with moderately severe postoperative pain after bunionectomy surgery.
This study is designed to compare the efficacy of NTM-001 to placebo. Intravenous (IV) morphine serves as an active comparator to determine assay sensitivity and support assessment of opioid-level analgesia for NTM-001. Effectiveness, safety, and tolerability parameters will be descriptively compared between treatment arms.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: NTM-001 Treatment Arm NTM-001 loading dose of 12.5 mg administered over approximately 60 seconds, followed by a continuous IV infusion at a rate of 3.5 mg/h for 24h, by a pre-programmed infusion pump. Subjects will also receive placebo to IV Morphine (injections). |
Drug: Ketorolac Tromethamine
Ketorolac tromethamine, alcohol free formulation, 1.0 mg/mL in saline solution (~0.9% NaCl) adjusted to a pH of ~7.4. Contained in a sterile, 200 mL polyolefin bag (filled with 125 mL of NTM-001).
Other Names:
Other: IV Placebo for Morphine
Placebo single use vials with saline (matching active morphine).
|
| Active Comparator: Morphine Treatment Arm A single IV morphine bolus (4 mg) every 4h for up to 24h. Subjects will also receive placebo to NTM-001. |
Drug: Morphine Sulfate
Morphine single use vials at 4 mg/mL, filled with 1 mL.
Other Names:
Other: Intravenous Placebo for NTM-001
Placebo alcohol free saline solution (~0.9% NaCl; matching active NTM-001). Contained in a sterile, 200 mL polyolefin bag (filled with 125 mL Placebo solution).
|
| Placebo Comparator: Placebo Treatment Arm Subjects randomized will receive placebos of both active treatments concomitantly. Placebo to NTM-001: Placebo "loading dose" applied over approximately 60 seconds, followed by a continuous IV infusion at a rate of 3.5 mL/h for 24h by a pre-programmed infusion pump. Placebo to IV morphine injections: A single IV placebo bolus every 4h for up to 24h. |
Other: Intravenous Placebo for NTM-001
Placebo alcohol free saline solution (~0.9% NaCl; matching active NTM-001). Contained in a sterile, 200 mL polyolefin bag (filled with 125 mL Placebo solution).
Other: IV Placebo for Morphine
Placebo single use vials with saline (matching active morphine).

Outcome Measures
Primary Outcome Measures
- Summed Pain Intensity Difference (SPID24) [0 to 24 hours after start of administration]
The primary endpoint is the Summed Pain Intensity Difference over 24h (SPID24) from start to end of administration of investigational medicinal product (IMP). Calculated as the weighted sum of the PID (difference between baseline at qualifying period and current pain intensity) collected at protocol scheduled time points through up to 24h after starting infusion of the IMP, using the following formula: SPID24 = Σ Wi * PIDi (1) where the Σ sums over all observations collected from the first assessment after the first IMP administration to Hour 24 and Wi is the time elapsed from the previous observation PIDi-1 to the current observation PIDi.
