Sulfopropanoic acid derivatives for treating neurodegenerative disorders: a patent spotlight
Rami A Al-Horani. Pharmaceutical patent analyst, 2024-06-20
Topic: Drug trials: efficacy and safety
The patent introduces a class of agents that target amyloid aggregation, and subsequently, reduce amyloid β-oligomer neurotoxicity. The class encompasses sulfopropanoic acid derivatives and is represented by tramiprosate and its prodrug ALZ-801 (valiltramiprosate). Clinical trials showed that ALZ-801 oral tablet is well tolerated and showed superior pharmacokinetic properties in healthy volunteers and Alzheimer's disease (AD) patients. Results from phase II & III trials of ALZ-801 in early AD have provided evidence of efficacy and to adjudicate the role of amyloid β-oligomers in AD pathogenesis. The confirmatory APOLLOE4 phase III trial of ALZ-801 in APOE4/4 homozygotes with early AD has been initiated. If ALZ-801 is approved, it will be among the first oral disease-modifying drugs for AD.
Key findings
- Clinical trials showed that ALZ-801 oral tablet is well tolerated and showed superior pharmacokinetic properties in healthy volunteers and Alzheimer's disease (AD) patients.
- Results from phase II & III trials of ALZ-801 in early AD have provided evidence of efficacy and to adjudicate the role of amyloid β-oligomers in AD pathogenesis.

How this study scored 43/100
Published in a peer-reviewed journal. Scored zero for study design, sample size, effect reported, studied in people and randomised / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record, multi-centre collaboration and free to read, so those were left out: it earned 24 of the 56 points we could judge it on, which is 43 out of 100.
