Attention-Deficit/Hyperactivity Disorder Rating Scale (DSM-IV ADHD RS) total score consists of 18 items directly adapted from the ADHD symptom list according to the DSM-IV. The DSM-IV ADHD RS total score was calculated as the sum of the Inattentive and the Hyperactive-Impulsive subscores. The 18 items are rated from 0 ("Never") to 4 ("Very often"). The total score ranges from 0(least symptomatic) to 72 (most symptomatic). Decrease in the DSM-IV ADHD RS total score indicates improvement, therefore a greater decrease (change at Final Visit compared to baseline) indicates a greater improvement in ADHD symptoms. 30% improvement: 100×(DSM-IV ADHD RS total score during Period 1 - DSM-IV ADHD RS total score at randomization(visit 2))/DSM-IV ADHD RS total score at randomization (visit 2) \<= - 30%.
SDS, a 5-self-rated questionnaire to measure the extent a pt's disability due to an illness/health problem interferes with work/school, social life/leisure, family life/home. First 3 items, pts are asked how their symptoms disrupted their reg. activities over the past 7d in ea. using a scale from 0(not at all)-10(extremely) Ea. subscale(work disability, social life disability, family life disability) can be scored independently or combined into a total score(sum of the non-missing responses for items 1-3)from 0-30,higher scores indicate significant functional impairmt. Subscale scores \>5 suggest impairment in that subscale area. Final 2 items ask pts about the # of days their symptoms caused them to miss school/work and # of days their symptoms caused them to be underproductive at school/work.(These items were not included in the total score.) Before responding to SDS items 1-3, pts were verbally instructed to recall the past 7d, items 4-5 refer to the last week w/in the item wording.
Treatment failure is defined as: 100×(DSM-IV ADHD RS total score during Period 3 - DSM-IV ADHD RS total score at re-randomization (visit 13))/DSM-IV ADHD RS total score at re-randomization (visit 13) \>= 30% AND 100×(DSM-IV ADHD RS total score during Period 3 - DSM-IV ADHD RS total score at randomization (visit 2))/DSM-IV ADHD RS total score at randomization (visit 2) \> - 30%. The ADHD-RS-IV is an 180item clinician rated scale to assess ADHD by DSM-IV-TR, defined criteria using symptom terminology appropriate for the adult population. Each item pertains to inattention (odd-numbered) or hyperactivity/impulsivity (even-numbered) and is scored on a scale of 0 (no symptoms) to 3 (severe symptoms). A total added score can range from 0-54

| Ritalin LA | EXPERIMENTAL | All participants started with Ritalin LA 20 mg/day and increased at weekly intervals in increments of 20 mg/day until reaching the patient's optimal dose 40, 60 or 80 mg/day). |
| Ritalin LA 40 mg | EXPERIMENTAL | In period 1 patients were given Ritalin LA 20 mg and up titrated to 40 mg at week 2, continued in same dose till week 9. Period 2- The dose of study medication was re-titrated for all patients (including those in the Placebo arm during Period 1) starting at 20 mg/day Ritalin LA and increased at weekly intervals in increments of 20 mg/day until reaching the patient's optimal dose 40 mg. Optimal dose was defined as the dose at which the investigator considered an optimal balance between control of symptoms and side effects was maintained for a period of at least one week prior to Week 14. In period 3, patients were re- randomized to either their optimal dose of medication (40, 60, or 80 mg/day) or Placebo from beginning of week 15 to end of week 40. |

Ritalin LA is used to treat Attention Deficit/Hyperactivity Disorder (ADHD). It is an extended-release formulation studied in adults with ADHD, including adults with childhood-onset ADHD. The clinical program enrolled adults aged 18 years and older across multiple countries in Phase 3 trials.
Ritalin LA is developed by Novartis AG, which trades under the ticker NVS. Novartis sponsored the Phase 3 clinical program evaluating methylphenidate hydrochloride extended release in adults with ADHD, including the efficacy and safety study NCT01259492 and the open-label extension NCT01338818.
Ritalin LA has been evaluated in Phase 3 clinical development for ADHD. Two Phase 3 trials are recorded, both completed, with no active trials ongoing. The program included a randomized, double-blind, placebo-controlled efficacy and safety study and an open-label extension study.
Ritalin LA has been studied in two completed Phase 3 trials: NCT01259492, an efficacy and safety study in adults with childhood-onset ADHD, and NCT01338818, an open-label extension in adults with ADHD. Together the trials enrolled 1,024 participants across the United States, Europe, South America, Asia, and South Africa.
Yes. Ritalin LA is also known as Ritalin LA 20 mg and Ritalin LA (methylphenidate hydrochloride extended release). The active ingredient is methylphenidate hydrochloride in an extended-release formulation, and the clinical trials are listed under the methylphenidate hydrochloride extended release name.
The Ritalin LA Phase 3 program enrolled 1,024 participants in total. NCT01259492 enrolled 725 adults with childhood-onset ADHD, and NCT01338818, the open-label extension, enrolled 299 adults with ADHD.
