Fasoracetam (INN Tooltip International Nonproprietary Name) is an experimental drug of the racetam group which was never marketed. [1] [2] [3] It is a putative nootropic that failed to show sufficient efficacy in clinical trials for vascular dementia. [3] The drug was also subsequently repurposed for treatment of a variety of other conditions, such as attention deficit hyperactivity disorder (ADHD), but effectiveness for ADHD was disappointing [4] and development of fasoracetam for most other conditions has been discontinued as well. [5] [6] [7] [8] In any case, it remains under development for treatment of DiGeorge syndrome. [6]

Contents

Pharmacology

Fasoracetam appears to modulate and stimulate all three groups of metabotropic glutamate receptors (mGluRs). [3] [1] It has been found to improve certain aspects of cognitive function in rodent studies. [3] [1] The drug is orally bioavailable and is excreted mostly unchanged in urine. [1] [3]

Chemistry

Fasoracetam is a racetam and a derivative of pyroglutamic acid. [1] [2]

History

Fasoracetam was developed in the late 1980s. [3] It was discovered by scientists at the Japanese pharmaceutical company Nippon Shinyaku, which brought it through Phase 3 clinical trials for vascular dementia, and abandoned it due to lack of efficacy. [3] [9] Subsequently, fasoracetam was repurposed for treatment of ADHD and other indications. [3] [5] [6] [7]

Scientists at Children's Hospital of Philadelphia led by Hakon Hakonarson have studied fasoracetam's potential use in attention deficit hyperactivity disorder. [3] Hakonarson's company neuroFix tried to bring the drug to market for this use; neuroFix acquired Nippon Shinyaku's clinical data as part of its efforts. [9] [10] neuroFix was acquired by Medgenics in 2015. [10] Medgenics changed its name to Aevi Genomic Medicine in 2016. [11]

Clinical trials in adolescents with ADHD who also have mGluR mutations started in 2016. [10] While fasoracetam may be effective in the treatment of ADHD in people with specific mGluR mutations, these represent around 10% of total ADHD cases, and fasoracetam is likely ineffective in all other cases. [12] [13] Studies showing improvements in cognitive function from fasoracetam have exclusively been done on rodents. [12]

Society and culture

Legality

Australia

Fasoracetam is a schedule 4 substance in Australia under the Poisons Standard (February 2020). [14] A schedule 4 substance is classified as "Prescription Only Medicine, or Prescription Animal Remedy – Substances, the use or supply of which should be by or on the order of persons permitted by State or Territory legislation to prescribe and should be available from a pharmacist on prescription." [14]

Research

Fasoracetam was originally developed for treatment of cognitive impairment related to dementia. [3] It reached phase 3 clinical trials for this indication. [3] However, development was discontinued due to lack of effectiveness and fasoracetam was never marketed. [3]

Fasoracetam (developmental code names AEVI-001, LAM-105, MDGN-001, NFC-1, NS-105) was under development by Avalo Therapeutics (previously Cerecor) for the treatment of attention deficit hyperactivity disorder (ADHD), autistic disorder, cognition disorders, DiGeorge syndrome, and major depressive disorder. [5] However, development for all indications was discontinued by 2018. [5] The drug (developmental code name NB-001) is also under development by Nobias Therapeutics for the treatment of DiGeorge syndrome and is in phase 2 clinical trials for this use as of October 2023. [6] A co-crystallized form of fasoracetam (developmental code name AEVI-004) is under development by Avalo Therapeutics for the treatment of ADHD, autistic disorder, and epilepsy as well. [7] However, no recent development has been reported for these indications as of April 2023. [7] Pharmaceutical developmental code names of fasoracetam include

The results of clinical studies of fasoracetam for ADHD have been disappointing. [4]

Atomoxetine, sold under the brand name Strattera, is a selective norepinephrine reuptake inhibitor medication used to treat attention deficit hyperactivity disorder (ADHD) and, to a lesser extent, cognitive disengagement syndrome. It may be used alone or along with psychostimulants. It enhances the executive functions of self-motivation, sustained attention, inhibition, working memory, reaction time and emotional self-regulation. Use of atomoxetine is only recommended for those who are at least six years old. It is taken orally. The effectiveness of atomoxetine is comparable to the commonly prescribed stimulant medication methylphenidate.

Coluracetam is a purported nootropic agent of the racetam family. It contains a chemical group that is a bioisostere of the 9-amino-tetrahydroacridine family. It was initially developed and tested by the Mitsubishi Tanabe Pharma Corporation for Alzheimer's disease. After the drug failed to reach endpoints in its clinical trials it was in-licensed by BrainCells Inc for investigations into major depressive disorder (MDD), which was preceded by being awarded a "Qualifying Therapeutic Discovery Program Grant" by the state of California. Findings from phase IIa clinical trials have suggested that it would be a potential medication for comorbid MDD with generalized anxiety disorder (GAD). BrainCells Inc is currently out-licensing the drug for this purpose. It may also have potential use in prevention and treatment of ischemic retinopathy and retinal and optic nerve injury.

Racetams, also sometimes known simply as pyrrolidones, are a class of drugs that share a pyrrolidone nucleus. Many, but not all, specifically have a 2-oxo-1-pyrrolidine acetamide (piracetam) nucleus. Some racetams, such as piracetam, aniracetam, oxiracetam, pramiracetam, and phenylpiracetam, are considered nootropics. Phenylpiracetam is also a stimulant. Others, such as levetiracetam, brivaracetam, and seletracetam, are anticonvulsants.

It is also used in Russian cosmonauts to improve physical, mental, and cognitive abilities. The drug is taken by mouth.

Attention deficit hyperactivity disorder management options are evidence-based practices with established treatment efficacy for ADHD. Approaches that have been evaluated in the management of ADHD symptoms include FDA-approved pharmacologic treatment and other pharmaceutical agents, psychological or behavioral approaches, combined pharmacological and behavioral approaches, cognitive training, neurofeedback, neurostimulation, physical exercise, nutrition and supplements, integrative medicine, parent support, and school interventions. Based on two 2024 systematic reviews of the literature, FDA-approved medications and to a lesser extent psychosocial interventions have been shown to improve core ADHD symptoms compared to control groups.
