Abstract

OBJECTIVE: To evaluate the efficacy and safety of 30, 50, and 70 mg/day lisdexamfetamine dimesylate compared with placebo in adults with attention-deficit/hyperactivity disorder (ADHD). METHOD: Following a 7- to 28-day washout, 420 adults aged 18 to 55 years with moderate to severe ADHD (DSM-IV-TR criteria) were treated with 30, 50, or 70 mg/day lisdexamfetamine or placebo, respectively, for 4 weeks (N = 119, 117, 122, and 62, respectively). The 50- and 70- mg/day groups underwent forced-dose titration. The primary efficacy measure was the clinician-determined ADHD Rating Scale (ADHD-RS) total score. The study was conducted from May 2006 to November 2006. RESULTS: Treatment groups were well matched at baseline, including in ADHD-RS scores. At endpoint, changes in ADHD-RS scores were significantly greater for each lisdexamfetamine dose than for placebo (placebo = -8.2, 30 mg/day lisdexamfetamine = -16.2, 50 mg/day lisdexamfetamine = -17.4, 70 mg/day lisdexamfetamine = -18.6; all p < .0001 vs. placebo), with no differences between doses. Significant differences relative to placebo were observed in each lisdexamfetamine group, beginning at week 1 and for each week throughout. The percentage of subjects who improved (Clinical Global Impressions-Improvement scale rating < or = 2) was significantly greater for each lisdexamfetamine dose than for placebo at each week and at endpoint (placebo = 29%, 30 mg/day lisdexamfetamine = 57%, 50 mg/day lisdexamfetamine = 62%, 70 mg/day lisdexamfetamine = 61%; all p < .01). Adverse events were generally mild and included dry mouth, decreased appetite, and insomnia. CONCLUSION: All 3 lisdexamfetamine doses were significantly more effective than placebo in the treatment of adults with ADHD, with improvements noted within 1 week. Lisdexamfetamine was generally well tolerated by these patients.

  • Discontinuations due to TEAEs with LDX in these studies (6.3% and 3.9%) are comparable to a published phase 2 study of LDX in BED, to other clinical studies of LDX for which LDX is indicated, and to other BED pharmacotherapy trials with other agents.

    “Discontinuations due to TEAEs with LDX in these studies (6.3% and 3.9%) are comparable to a published phase 2 study of LDX in BED (McElroy et al, 2015), to other clinical studies of LDX for which LDX is indicated (Adler et al, 2008; Wigal et al, 2010), and to other BED pharmacotherapy trials with other agents (Claudino et al, 2007; McElroy et al, 2003, 2007a, b).”
  • The safety and tolerability profile of LDX observed regarding overall TEAEs, TEAEs leading to discontinuation, vital signs, and ECGs were consistent with published reports in adults with BED or attention-deficit/hyperactivity disorder.

    “The safety and tolerability profile of LDX observed regarding overall TEAEs, TEAEs leading to discontinuation, vital signs, and ECGs were consistent with published reports in adults with BED (McElroy et al, 2015) or attention-deficit/hyperactivity disorder (Adler et al, 2008; Wigal et al, 2010).”
  • LDX is not metabolized by cytochrome P450 enzymes and is unlikely to be involved in drug interactions involving CYP enzymes or P-glycoprotein; however, it is contraindicated during or within 2 weeks following administration of monoamine oxidase inhibitors.

  • In placebo-controlled LDX trials in ADHD, participants were considered treatment responders if they had a ≥ 30% reduction in ADHD symptoms using a standardized scale.

    “in placebo-controlled LDX trials in ADHD, participants were considered treatment “responders” if they had a ≥ 30% reduction in ADHD symptoms using a standardized scale [27–29].”
  • Improvements observed from LDX versus placebo in this trial were comparable to those observed in LDX interventions for adults with ADHD.

    “Improvements observed from LDX versus placebo in this trial were comparable to those observed in LDX interventions for adults with ADHD [16,27–29].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
