Objective To evaluate the efficacy and safety of osmotic-release methylphenidate (OROS-MPH) compared to placebo for attention deficit hyperactivity disorder (ADHD) and impact on substance treatment outcomes in adolescents concurrently receiving cognitive behavioral therapy (CBT) for substance use disorders (SUD). Method 16-week randomized controlled multi-site trial of OROS-MPH + CBT versus placebo + CBT in 303 adolescents (aged 13-18), meeting DSM-IV diagnostic criteria for ADHD and SUD. Primary outcomes: (1) ADHD- clinician-administered ADHD Rating Scale (ADHD-RS), adolescent informant; (2) Substance- adolescent reported days of use in the past 28 days. Secondary outcome measures included parent ADHD-RS and weekly urine drug screens (UDS). Results There were no group differences on reduction in ADHD-RS scores (OROS-MPH: −19.2, 95% confidence interval [CI], −17.1 to −21.2; placebo,−21.2, 95% CI, −19.1 to −23.2) or reduction in days of substance use (OROS-MPH: −5.7 days, 95% CI, 4.0-7.4; placebo: −5.2 days, 95% CI, 3.5-7.0). Some secondary outcomes favored OROS-MPH including lower parent ADHD-RS scores at 8 (mean difference [md]=4.4, 95% CI, 0.8-7.9) and 16 weeks (md=6.9; 95% CI, 2.9-10.9) and more negative UDS in OROS-MPH (mean=3.8) compared to placebo (mean=2.8; P=0.04). Conclusions OROS-MPH did not show greater efficacy than placebo for ADHD or on reduction in substance use in adolescents concurrently receiving individual CBT for co-occurring SUD. However, OROS-MPH was relatively well tolerated and was associated with modestly greater clinical improvement on some secondary ADHD and substance outcome measures.

PURPOSE This phase III, placebo-controlled, randomized trial was designed to investigate efficacy and safety of two doses of denileukin diftitox (DD; DAB(389)-interleukin-2 [IL-2]), a recombinant fusion protein targeting IL-2 receptor-expressing malignant T lymphocytes, in patients with stage IA to III, CD25 assay-positive cutaneous T-cell lymphoma (CTCL), including the mycosis fungoides and Sézary syndrome forms of the disease, who had received up to three prior therapies. The primary end point was overall response rate (ORR). PATIENTS AND METHODS Patients (N = 144) with biopsy-confirmed, CD25 assay-positive CTCL were randomly assigned to DD 9 microg/kg/d (n = 45), DD 18 microg/kg/d (n = 55), or placebo infusions (n = 44), administered for 5 consecutive days every 3 weeks for up to eight cycles. Patients were monitored for drug efficacy, clinical benefit, and safety of DD. RESULTS ORR was 44% for all participants treated with DD (n = 100; 10% complete response [CR] and 34% partial response [PR]) compared with 15.9% for placebo-treated patients (2% CR and 13.6% PR). ORR was higher in the 18 microg/kg/d group versus the 9 microg/kg/d group (49.1% v 37.8%, respectively), and both doses were significantly superior to placebo. Progression-free survival (PFS) was significantly longer (median, > 2 years) for both DD doses compared with placebo (median, 124 days; P < .001). Rates of moderately severe and severe adverse events (AEs) were slightly higher in the DD groups, whereas moderate and mild AEs were similar to placebo. No statistical differences were observed for drug-related serious AEs. CONCLUSION DD had a significant and durable effect on ORR and PFS with an acceptable safety profile in patients with early- and late-stage CTCL.
