Study Endpoints

Primary Endpoints

The primary measure of efficacy will be the clinician-administered ADHD-rating scale (ADHD-RS-IV)
Baseline (following ADHD medication washout of 7-28 days)

The ADHD-RS-IV consists of 18 items designed to reflect current symptomatology of ADHD. Each item is scored on a 4-point scale ranging from 0 (no symptoms) to three (severe symptoms), with the total score for the rating scale ranging from 0 to 54.

The evaluation of safety will be based on the occurrence of treatment emergent AEs and specific evaluation of vitals signs, ECG, laboratory and physical examination.
Throughout the study period of approximately 20 months
Change from Baseline in the ADHD-rating scale 4th Edition (ADHD-RS-IV) total score to the Endpoint assessment.

Frequently asked questions about Neutral salts of dextroamphetamine, USP, amphetamine, USP, d-amphetamine saccharate, d, I-amphetamine aspartate

What is neutral salts of dextroamphetamine, USP, amphetamine, USP, d-amphetamine saccharate, d,I-amphetamine aspartate used for?

It is an investigational small molecule being studied for Attention Deficit Disorder With Hyperactivity (ADHD) in adults. The clinical program enrolled adults aged 18 years and older with ADHD, including one trial in adults with moderately symptomatic ADHD. It is being developed by Takeda Pharmaceutical Company Limited.

What does neutral salts of dextroamphetamine, USP, amphetamine, USP, d-amphetamine saccharate, d,I-amphetamine aspartate target?

Its molecular target is INSR, the insulin receptor, and it acts as an agonist at that target. This target class distinguishes it from typical ADHD stimulant pharmacology, which is why the INSR agonist mechanism is a defining feature of how this asset is characterized in the pipeline.

Who makes neutral salts of dextroamphetamine, USP, amphetamine, USP, d-amphetamine saccharate, d,I-amphetamine aspartate?

Takeda Pharmaceutical Company Limited is the developer of this asset, trading under the ticker TAK. The company sponsored the clinical program, which includes four completed trials in adults with ADHD. The trials were conducted under the SPD465 designation, a name used in the study titles.

What phase is neutral salts of dextroamphetamine, USP, amphetamine, USP, d-amphetamine saccharate, d,I-amphetamine aspartate in?

The asset has reached Phase 3. Three of its four trials are Phase 3 studies, and one is a Phase 2 study. All four trials are completed, with no active trials currently listed. It remains an investigational product and is not approved for marketing based on this development record.

What clinical trials is neutral salts of dextroamphetamine, USP, amphetamine, USP, d-amphetamine saccharate, d,I-amphetamine aspartate in?

Four completed trials make up the program: NCT00202605, a Phase 2 safety and efficacy study in 72 adults; NCT00152035, a Phase 3 safety study in 505 adults; NCT00152022, a Phase 3 efficacy and safety study in 412 adults with moderately symptomatic ADHD; and NCT00150579, a Phase 3 efficacy and safety study in 240 adults.

Is neutral salts of dextroamphetamine, USP, amphetamine, USP, d-amphetamine saccharate, d,I-amphetamine aspartate the same as SPD465?

Yes. SPD465 is the development code used for this asset in its clinical trial titles, so searches for SPD465 refer to the same program. The full chemical name describes a mixture of neutral amphetamine salts, and the alternative naming variants, including sulfate and aspartate monohydrate forms, all refer to this same asset.
