RESUMEN
OBJECTIVE: To evaluate the effect of perioperative meloxicam IV 30 mg on opioid consumption in primary total knee arthroplasty (TKA). DESIGN: Multicenter, randomized, double-blind, placebo-controlled trial. SUBJECTS: In total, 181 adults undergoing elective primary TKA. METHODS: Subjects received meloxicam 30 mg or placebo via an IV bolus every 24 hours, the first dose administered prior to surgery as part of a multimodal pain management protocol. The primary efficacy parameter was total opioid use from end of surgery through 24 hours. RESULTS: Meloxicam IV was associated with less opioid use versus placebo during the 24 hours after surgery (18.9 ± 1.32 vs 27.7 ± 1.37 mg IV morphine equivalent dose; P < 0.001) and was superior to placebo on secondary endpoints, including summed pain intensity (first dose to 24 hours postdosing, first dose to first assisted ambulation, and first dose to discharge) and opioid use (48-72 hrs., 0-48 hrs., 0-72 hrs., hour 0 to end of treatment, and the first 24 hours after discharge). Adverse events (AEs) were reported for 69.9% and 92.0% of the meloxicam IV and placebo groups, respectively; the most common AEs were nausea (40% vs. 59%), vomiting (16% vs 22%), hypotension (14% vs 15%), pruritus (15% vs 11%), and constipation (11% vs 13%). CONCLUSIONS: Perioperative meloxicam IV 30 mg as part of a multimodal analgesic regimen for elective primary TKA reduced opioid consumption in the 24-hour period after surgery versus placebo and was associated with a lower incidence of AEs typically associated with opioid use.

Aim: Evaluate safety/efficacy of intravenous meloxicam in a colorectal enhanced recovery after surgery protocol. Methods: Adults undergoing primary open or laparoscopic colorectal surgery with bowel resection and/or anastomosis received meloxicam IV 30 mg (n = 27) or placebo (n = 28) once daily beginning 30 min before surgery. Results: Adverse events: meloxicam IV, 85%; placebo, 93%. Adverse events commonly associated with opioids: 41 versus 61% - including nausea (33 vs 50%), vomiting (19 vs 18%) and ileus (4 vs 18%). Wound healing satisfaction scores (physician-rated), clinical laboratory findings and vital signs were similar in both groups. No anastomotic leaks were reported. Opioid consumption, postoperative pain intensity, length of stay and times to first bowel sound, first flatus and first bowel movement were significantly lower with meloxicam IV versus placebo. Most subjects (>92%) were satisfied with postoperative pain medication. Conclusion: Meloxicam IV was generally well tolerated and associated with decreased opioid consumption, lower resource utilization and functional benefits. Clinical Trial Registration: NCT03323385 (ClinicalTrials.gov).

Meloxicam for intravenous use (meloxicam iv.) is a nanocrystal formulation with improved dissolution properties and shortened time to peak plasma concentrations versus oral meloxicam. In Phase III and IIIb trials, 30 mg once daily relieved pain following pre- or postoperative administration in orthopedic, abdominal and colorectal surgeries. Meloxicam iv. was associated with reduced opioid consumption, the clinical benefit of which remains unclear. The drug may be administered alone or in combination with other non-nonsteroidal anti-inflammatory drugs. In Phase III trials, it demonstrated adverse event profile similar to placebo, with nausea, constipation, vomiting and headache occurring most frequently. Meloxicam iv. does not appear to adversely affect platelet function or wound-healing parameters. No new safety signals were detected in the Phase IIIb studies.

OBJECTIVE: A Phase 3 randomized multicenter, double-blind, placebo-controlled trial (NCT02720692) compared once-daily intravenous (IV) meloxicam 30 mg to placebo, when added to the standard of care pain management regimens, in adults with moderate-to-severe pain following major elective surgery and concluded that meloxicam IV had a safety profile similar to placebo and reduced opioid consumption. METHODS: In this post hoc subgroup analysis of orthopedic surgery subjects, 379 subjects received meloxicam IV 30 mg or IV-administered placebo every 24 hrs for ≤7 doses. Safety was assessed via AEs, laboratory tests, vital signs, and ECG, with an emphasis on specific AEs, including injection site reactions, bleeding, cardiovascular, hepatic, renal, thrombotic, and wound healing events. Daily opioid consumption was assessed during treatment. RESULTS: Among meloxicam IV-treated subjects, 64.7% experienced ≥1 AE versus 68.8% of placebo-treated subjects. Investigators assessed most AEs to be mild or moderate in intensity and unrelated to treatment. Total opioid consumption (36.8 mg versus 50.3 mg IV morphine equivalent dose; P=0.0081) and opioid consumption during time points 0â24, 24â48, 0â48, and 0â72 hrs were statistically significantly lower in the meloxicam IV group. CONCLUSION: Meloxicam IV demonstrated no significant differences in the number and frequency of AEs versus placebo in subjects following orthopedic surgery. Opioid consumption was reduced in the meloxicam IV group versus placebo. TRIAL REGISTRATION: ClinicalTrials.gov (Identifier: NCT02720692).
RESUMEN
BACKGROUND: An intravenous (IV) formulation of meloxicam was developed for moderate-to-severe pain management. This study evaluated the safety and efficacy of meloxicam IV after open abdominal hysterectomy. Meloxicam IV is an investigational product not yet approved by the US Food and Drug Administration. METHODS: Women (N = 486) with moderate-to-severe pain after open abdominal hysterectomy were enrolled in this multicenter, randomized, double-blind, placebo- and active-controlled trial. Subjects were randomized to receive a single dose of meloxicam IV (5-60 mg), placebo, or morphine (0.15 mg/kg) in ≤6 hours after morphine dosing on postoperative day 1 and were evaluated for 24 hours. Rescue morphine (≈0.15 mg/kg IV) was available if needed for pain not relieved by the study medication. In an open-label extension (N = 295), meloxicam IV was administered once daily for the remaining hospital stay (or per the investigator's discretion). The coprimary efficacy end points were the summed pain intensity difference (SPID24) and total pain relief (TOTPAR24) from hour 0 to 24 hours after dosing. Effect size, the standardized difference between means reported in standard deviation (SD) units, was calculated to indicate the magnitude of the difference in the mean analgesic effect measured for different intervention groups. RESULTS: Subjects who received morphine or meloxicam IV had a median time to first perceptible pain relief within 6-8 minutes. Morphine and meloxicam IV 5-60 mg produced statistically significant differences than placebo in SPID24 and TOTPAR24. SPID24 (standard error [SE]) for meloxicam IV 5-60 mg ranged from -56276.8 (3926.46) to -33517.1 (3930.1; P < .001); SPID24 (SE) for morphine and placebo were -29615.8 (3869.2; P < .001) and 4555.9 (3807.1), respectively. SPID24 effect sizes (95% confidence intervals) for the 60, 30, 15, 7.5, and 5 mg meloxicam IV doses and morphine were 1.93 (1.61-2.25), 2.00 (1.65-2.35), 1.70 (1.35-2.05), 1.28 (0.95-1.60), 1.25 (0.90-1.61), and 1.12 (0.77-1.45) SDs, respectively. TOTPAR24 (SE) for meloxicam IV 5-60 mg ranged from 3104.5 (155.28) to 4130.4 (191.17; P < .001); TOTPAR24 (SE) for morphine and placebo were 2723.3 (188.4; P < .001) and 1100.6 (185.4), respectively. TOTPAR24 effect sizes (95% confidence interval) for the 60, 30, 15, 7.5, and 5 mg meloxicam IV doses and morphine were 2.03 (1.70-2.35), 2.05 (1.70-2.40), 1.78 (1.43-2.13), 1.35 (1.03-1.67), 1.37 (1.01-1.72), and 1.10 (0.75-1.45) SDs, respectively. The mean total opioid consumed (SD) during the double-blind phase was 4.6 (8.17), 5.3 (8.85), 5.9 (7.85), 8.5 (9.67), 9.3 (9.47), 9.6 (8.12), and 16.0 (10.15) mg for patients in the 60, 30, 15, 7.5, and 5 mg meloxicam IV, morphine, and placebo groups, respectively. Generally, meloxicam IV was well tolerated, evidenced by the incidence of adverse events compared to placebo and lack of deaths and treatment-related serious adverse events. CONCLUSIONS: A meloxicam IV dose of 5-60 mg was generally well tolerated and appeared to reduce opioid consumption in subjects with moderate-to-severe pain after open abdominal hysterectomy. Once-daily administration of meloxicam IV produced analgesic effect within 6-8 minutes postdose that was maintained over a 24-hour dosing interval.

An intravenous (IV) formulation of meloxicam is being studied for moderate to severe pain management. This phase 3, randomized, multicenter, double-blind, placebo-controlled trial evaluated the safety of once-daily meloxicam IV 30 mg in subjects following major elective surgery. Eligible subjects were randomized (3:1) to receive meloxicam IV 30 mg or placebo administered once daily. Safety was evaluated via adverse events, clinical laboratory tests, vital signs, wound healing, and opioid consumption. The incidence of adverse events was similar between meloxicam IV- and placebo-treated subjects (63.0% versus 65.0%). Investigators assessed most adverse events as mild or moderate in intensity and unrelated to treatment. Adverse events of interest (injection-site reactions, bleeding, cardiovascular, hepatic, renal, thrombotic, and wound-healing events) were similar between groups. Over the treatment period, meloxicam IV was associated with a 23.6% (P = .0531) reduction in total opioid use (9.2 mg morphine equivalent) compared to placebo-treated subjects. The results suggest that meloxicam IV had a safety profile similar to that of placebo with respect to numbers and frequencies of adverse events and reduced opioid consumption in subjects with moderate to severe postoperative pain following major elective surgery.

BACKGROUND AND OBJECTIVES: To describe the safety and tolerability of intravenous meloxicam compared with placebo across all phase II/III clinical trials. METHODS: Safety data and opioid use from subjects with moderate to severe postoperative pain who received ≥1 dose of intravenous meloxicam (5-60 mg) or placebo in 1 of 7 studies (4 phase II; 3 phase III) were pooled. Data from intravenous meloxicam 5 mg, 7.5 mg and 15 mg groups were combined (low-dose subset). RESULTS: A total of 1426 adults (86.6% white; mean age: 45.8 years) received ≥1 dose of meloxicam IV; 517 (77.6% white; mean age: 46.7 years) received placebo. The incidence of treatment-emergent adverse events (TEAEs) in intravenous meloxicam and placebo-treated subjects was 47% and 57%, respectively. The most commonly reported TEAEs across treatment groups (intravenous meloxicam 5-15 mg, 30 mg, 60 mg and placebo, respectively) were nausea (4.3%, 20.8%, 5.8% and 25.3%), headache (1.5%, 5.6%, 1.6% and 10.4%), vomiting (2.8%, 4.6%, 1.6% and 7.4%) and dizziness (0%, 3.5%, 1.1% and 4.8%). TEAE incidence was generally similar in subjects aged >65 years with impaired renal function and the general population. Similar rates of cardiovascular events were reported between treatment groups. One death was reported (placebo group; unrelated to study drug). There were 35 serious adverse events (SAEs); intravenous meloxicam 15 mg (n=5), intravenous meloxicam 30 mg (n=15) and placebo (n=15). The SAEs in meloxicam-treated subjects were determined to be unrelated to study medication. Six subjects withdrew due to TEAEs, including three treated with intravenous meloxicam (rash, localized edema and postprocedural pulmonary embolism). In trials where opioid use was monitored, meloxicam reduced postoperative rescue opioid use. CONCLUSIONS: Intravenous meloxicam was generally well tolerated in subjects with moderate to severe postoperative pain. TRIAL REGISTRATION NUMBERS: NCT01436032, NCT00945763, NCT01084161, NCT02540265, NCT02678286, NCT02675907 and NCT02720692.
RESUMEN
BACKGROUND: A nanocrystal intravenous (IV) formulation of meloxicam is being studied with the aim of providing postoperative analgesia. METHODS: This randomized, multicenter, double-blind, placebo-controlled trial evaluated meloxicam IV 30 mg or placebo (≤ 3 doses) in 219 subjects undergoing abdominoplasty. The primary endpoint was the summed pain intensity difference over 24 hours postdose (SPID24). RESULTS: Meloxicam IV-treated subjects had a statistically significant reduction in the least squares mean of SPID24 compared with placebo-treated subjects (-4,262.1 versus -3,535.7; P = 0.0145). Meloxicam IV was associated with statistically significant differences over placebo on several other secondary endpoints, including other SPID intervals (ie, SPID12, SPID48, and SPID24-48), achievement of perceptible pain relief, the proportion of subjects with a ≥ 30% improvement in the first 24 hours, and Patient Global Assessment of pain at hour 48. Meloxicam IV was also associated with a reduction in the number of subjects receiving opioid rescue medication during hours 24-48 and the total number of doses of opioid rescue analgesia. Meloxicam IV was generally well tolerated, with the numbers and frequencies of adverse events similar to that of the placebo group. There was no evidence of an increased risk of adverse events commonly associated with nonsteroidal anti-inflammatory drugs including bleeding, thrombotic, cardiovascular, renal, hepatic, cardiovascular, injection site, and wound healing events. CONCLUSION: Meloxicam IV provided sustained pain relief and generally was well tolerated in subjects with moderate-to-severe pain following abdominoplasty.
RESUMEN
OBJECTIVE: This randomized, double-blind, placebo-controlled study evaluated the safety and efficacy of an intravenous (IV) nanocrystal formulation of meloxicam in subjects with moderate-to-severe pain following a standardized unilateral bunionectomy. METHODS: Fifty-nine subjects aged 18-72 years were randomized to receive doses of either 30 mg (n=20) or 60 mg (n=20) meloxicam IV or placebo (n=19), administered once daily as bolus IV injections over 15-30 seconds (two or three doses). Safety, the primary objective, was assessed by physical examination, clinical laboratory tests, and the incidence of adverse events (AEs). Efficacy was evaluated by examining summed pain intensity differences over the first 48 hours (SPID48) using analysis of covariance models. Use of opioid rescue analgesic agents was evaluated. RESULTS: Generally, AEs were mild-to-moderate in intensity, and their incidence was similar across the three treatment groups. No serious AEs were reported; there were no withdrawals due to AEs, including injection-related AEs. The estimated effect size for SPID48 versus placebo was 1.15 and 1.01 for meloxicam IV doses 30 mg and 60 mg, respectively (P≤0.01). Both doses produced significantly greater pain reductions versus placebo (P≤0.05) at all evaluated times/ intervals during the 48-hour period. The proportions of subjects with ≥30% and ≥50% overall reduction in pain from baseline after 6 and 24 hours were significantly higher with meloxicam IV 30 mg doses versus placebo, but not with meloxicam IV 60 mg doses. The time to first use of rescue medication was significantly longer versus placebo with meloxicam IV 60 mg (P<0.05), but not with meloxicam IV 30 mg doses. CONCLUSION: Meloxicam IV was generally safe and well tolerated in subjects with moderate-to-severe post-bunionectomy pain. Once-daily administration of meloxicam IV 30 mg and 60 mg exhibited rapid onset of analgesia (as early as 15 minutes) with maintenance of analgesic effect for two consecutive 24-hour periods.
RESUMEN
OBJECTIVE: To evaluate the analgesic efficacy and safety of a novel intravenous (IV) formulation of meloxicam (30 mg) in patients with moderate-to-severe pain following a standardized, unilateral bunionectomy with first metatarsal osteotomy and internal fixation. MATERIALS AND METHODS: Patients who met the criteria for moderate-to-severe postoperative pain were randomized to receive bolus injections of meloxicam IV 30 mg (n=100) or placebo (n=101) administered once daily. The primary efficacy endpoint was the Summed Pain Intensity Difference over 48 hours (SPID48). Secondary efficacy endpoints included sum of time-weighted pain intensity differences (SPID) values at other timepoints/intervals, time to first use of rescue analgesia, and number of rescue doses taken. Safety assessments included the incidence of adverse events (AEs), physical examinations, laboratory tests, 12-lead electrocardiography, and wound healing. RESULTS: Patients randomized to meloxicam IV 30 mg exhibited a statistically significant difference in SPID48 versus the placebo group (P=0.0034). Statistically significant differences favoring meloxicam IV over placebo were also observed for secondary efficacy endpoints, including SPID at other times/intervals (SPID6: P=0.0153; SPID12: P=0.0053; SPID24: P=0.0084; and SPID24-48: P=0.0050) and first use of rescue medication (P=0.0076). Safety findings indicated that meloxicam IV 30 mg was generally well tolerated; no serious AEs or bleeding events were observed. Most AEs were assessed by the investigator to be mild in intensity, and no patients discontinued due to AEs. There were no meaningful differences between the study groups in vital signs, electrocardiographic findings, or laboratory assessments. In most cases, investigators found that wound healing followed a normal course and mean wound-healing satisfaction scores were similar for meloxicam IV 30 mg and placebo. DISCUSSION: Meloxicam IV doses of 30 mg provided effective pain relief when administered once daily by bolus injection to patients with moderate-to-severe pain following bunionectomy, and had an acceptable safety profile.

This randomized, controlled phase 2 study was conducted to evaluate the analgesic efficacy, safety, and tolerability of single intravenous (IV) doses of 15 mg, 30 mg, and 60 mg meloxicam compared with oral ibuprofen 400 mg and placebo after dental impaction surgery. The primary efficacy end point was the sum of time-weighted pain intensity differences for 0-24 hours postdose. Among 230 evaluable subjects, meloxicam IV 60 mg produced the greatest reduction in pain, followed by the 30-mg and 15-mg doses. Statistically significant differences in summed pain intensity differences over 24 hours were demonstrated for each active-treatment group vs placebo (favoring active treatment) and for meloxicam IV 30 mg and 60 mg vs ibuprofen 400 mg (favoring meloxicam IV). Moreover, there was a statistically significant dose response for meloxicam IV 15 mg to 60 mg. The onset of action for meloxicam IV was rapid and sustained; significant differences in pain intensity differences were detected as early as 10 minutes postdose and lasted through the 24-hour postdose period. Subjects in the meloxicam IV groups were more likely than placebo recipients to achieve perceptible and meaningful pain relief and were less likely to use rescue medication. Patient-reported global evaluation showed that meloxicam IV 60 mg had the highest rating. There were no deaths, serious adverse events, or discontinuations due to adverse events. The incidence of subjects with ≥1 treatment-emergent adverse event was greatest in the placebo group, followed by the groups that received ibuprofen, meloxicam IV 15 mg, 30 mg, and 60 mg. Nausea was the most commonly reported treatment-emergent adverse event. CLINICAL TRIAL REGISTRATION NUMBER: NCT00945763.

It is recognized that testosterone (T) levels decrease in men with age, as does sexual function. We hypothesize that T supplementation in hypogonadal men with sexual dysfunction will restore certain elements of sexual function. Hypogonadal male subjects (total T < or = 300 ng/dL, n = 406, mean age 58 years) reporting one or more symptoms of low testosterone were randomized to T gel (50 mg/d and 100 mg/d), T patch, or placebo. Twenty-four-hour pharmacokinetic profiles for T were obtained. The 3 primary end points evaluated at 30 and 90 days posttreatment included a significant change in the frequency of intercourse and nighttime erections per 7-day week as well as a change in sexual desire measured on a Likert-type scale and calculated as a mean daily score. At day 30, a significant increase from baseline in sexual desire was noted for those on 100 mg/d T gel compared with those on 50 mg/d T gel, T patch, or placebo (1.2 vs 0.4, 0.7, and 0.4, respectively). A significant increase from baseline in the frequency of nighttime erections was also noted for those on 100 mg/d T gel compared with those on 50 mg/d T gel or placebo (51% of subjects in the 100 mg/d T gel group had an increase in frequency vs 30% for the 50 mg/d T gel group and 26% in the placebo group). Finally, a significant increase from baseline in the frequency of intercourse was evidenced for those on 100 mg/d T gel compared with those on T patch or placebo (39% of subjects in the 100 mg/d T gel group had an increase in frequency vs 21% for the T patch group and 24% in the placebo group). Similar results were seen for 100 mg/d T gel at day 90 for sexual desire and nighttime erections vs placebo. These data demonstrate a clear relationship between restoring serum T concentrations and improvement in certain parameters of sexual function. We propose that threshold T levels are needed in order to significantly affect improvements in sexual functioning.
