Abstract

Objective To examine lisdexamfetamine dimesylate (LDX) efficacy and safety versus placebo in adolescents with attention-deficit/hyperactivity disorder (ADHD).Method Adolescents (13 through 17) with at least moderately symptomatic ADHD (ADHD Rating Scale IV: Clinician Version [ADHD-RS-IV] score ≥28) were randomized to placebo or LDX (30, 50, or 70 mg/d) in a 4-week, forced-dose titration, double-blind study. Primary and secondary efficacy measures were the ADHD-RS-IV, Clinical Global Impressions-Improvement (CGI-I), and Youth QOL-Research Version (YQOL-R). Safety assessments included treatment-emergent adverse events (TEAEs), vital signs, laboratory findings, physical examinations, and ECG.Results Overall, 314 participants were randomized; 309 were in efficacy analyses and 49 withdrew (11 due to TEAEs). Least squares mean (SE) change from baseline at endpoint in ADHD-RS-IV total scores were -18.3 (1.25), -21.1 (1.28), -20.7 (1.25) for 30, 50, and 70 mg/d LDX, respectively; -12.8 (1.25) for placebo (p ≤ .0056 versus placebo for each). Differences in ADHD-RS-IV total scores favored all LDX doses versus placebo at all weeks (p ≤ .0076). On the CGI-I, 69.1% of participants were rated very much/much improved at endpoint with LDX all doses versus placebo (39.5%) (p < .0001). YQOL-R changes at endpoint scores for LDX groups versus placebo were not significant. Commonly reported LDX (all doses combined) TEAEs (≥5%) were decreased appetite, headache, insomnia, decreased weight, and irritability. Small mean increases in pulse and blood pressure and no clinically meaningful trends in ECG changes were noted with LDX.Conclusions LDX at all doses was effective versus placebo in treating adolescent ADHD and demonstrated a safety profile consistent with previous LDX studies.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Risk of bias was low in the randomized studies of Findling et al. (2011), Newcorn et al. (2017b), and Spencer et al. (2006), and high in all other studies.

    “We rated the risk of bias as low in the randomized studies of Findling et al. (2011) [42], Newcorn et al. (2017b) [34], and Spencer et al. (2006) [25], and as high in all other studies (Table 2).”
  • RCTs showed efficacy and tolerability of LDX in child and adolescent ADHD, but each trial had a limited sample size.

    “Although randomized controlled trials (RCTs) showed the efficacy and tolerability of LDX in child and adolescent ADHD,10–13 each trial had a limited sample size.”
  • Previous studies documented that LDX was an effective, safe, and well-tolerated stimulant in the treatment of ADHD in children and adolescents.

    “Previous studies documented that LDX was an effective, safe, and well-tolerated stimulant in the treatment of ADHD in children and adolescents.10–13”
  • In a 4-week randomized controlled trial of 314 adolescents with ADHD, lisdexamfetamine did well across all doses (30 mg, 50 mg, and 70 mg) compared with placebo, as evidenced by improvement in scores on ADHD-RS-IV, CGI, and Youth Quality of Life-Research Version.

    “In a 4-week, randomized, controlled trial26 involving 314 adolescents with ADHD who were randomized to receive placebo or to be part of a forced titration arm of lisdexamfetamine (30 mg, 50 mg, and 70 mg), lisdexamfetamine did well across all of the doses in comparison with placebo, as evidenced by improvement in scores on the ADHD-RS-IV, CGI, and Youth Quality of Life-Research Version.”
  • A previously reported 4-week randomized, double-blind, placebo-controlled trial of LDX reported greater improvement in ADHD symptoms from baseline on ADHD-RS-IV total score at the end of the study versus placebo.

    “A previously reported 4 week, randomized, double-blind, placebo-controlled trial (Findling et al. 2011) of lisdexamfetamine dimesylate (LDX), a long-acting prodrug stimulant indicated for ADHD in children (ages 6–12 years), adolescents (ages 13–17 years), and adults, reported greater improvement in ADHD symptoms from baseline on Attention-Deficit/Hyperactivity Disorder Rating Scale IV (ADHD-RS-IV)”

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.
