The hunt for an Alzheimer’s illness diagnosis has been
catastrophic for the past 14 years. 

The latest disaster came in September, when Axovant pronounced it failed
a pivotal late-stage hearing for its drug, intepirdine. 

Alzheimer’s affects more than 5 million Americans, a
series that’s approaching to balloon
to

 
13.8 million by
2050
 
. There are only 4 drugs
that have been authorized to provide the symptoms of the disease, and
the many new drug capitulation happened in 2003.

2017 in sold has been a
tough year for Alzheimer’s failures. In Feb alone,

Lundbeck discontinued two of its trials, Merck
dropped one of its studies, and Accera
unsuccessful a late-stage trial as well. Axovant’s trial
results are the last major results to come out in 2017, with the
next ones reading out in 2018 and a major call of results
approaching in 2019.  

Starting earlier

Research has dynamic that years — even decades — before a
person competence start showing symptoms, amyloid beta deposits in the
brain that are evil of Alzheimer’s
disease can
start to accumulate. By the time we start seeing
symptoms of dementia, researchers think, it competence already be too
late to do much.

So preventing any course at that theatre is something
researchers are pinning a lot of wish on. There’s one
research effort going
on in Colombia that’s contrast out an amyloid-related
drug in an extended family with a singular genetic turn that
leads to early-onset Alzheimer’s. That study is in people who are
still deliberate cognitively healthy, so if the drug is means to
forestall cognitive decline, it could be a breakthrough.

What’s ahead

According to PhRMA, there are more than a dozen experimental
treatments that are still in
proviso 3, the latest theatre of clinical trials before companies
benefaction their information to the FDA. Here are some of the ones to look
out for in the next year or two. 

  • VTV Therapeutics, a tiny company in
    North Carolina, has an Alzheimer’s drug in late-stage
    trials called azeliragon that inhibits the RAGE
    receptor, ideally assisting people with amiable Alzheimer’s
    check cognitive decline. Its proviso 3 hearing is approaching to wrap
    up in early 2018. The company got enlivening proviso 2 results
    on the drug, which has been in the works for about 17 years.
    Even so, there’s no pledge it will succeed. “We are doing a sound and rigorous
    experiment,” Dr. Larry Altstiel, VTV’s arch medical
    officer told Business Insider. 
  • Biogen’s aducamumab, a BACE
    inhibitor, 
    is going after
    the amyloid
    hypothesis,” or the thought that targeting beta amyloid
    deposits in the brain to transparent them out is the way to go
    about treating the disease. It’s approaching to have results in
    2019 or early 2020.  
  • Lanabecestat, AstraZeneca’s BACE
    inhibitor, is going be reading out in 2019. Like
    Biogen, it’s going after the amyloid hypothesis. 
  • Eli Lily’s solanezumab
    failed a proviso 3 hearing in patients with amiable dementia
    in Nov 2016, but has plans to keep trying the drug in
    pre-clinical stages of the illness to see if it works
    preventatively. Solanezumab is going after the amyloid
    supposition as well. While 3 trials have been disconnected,
    the fourth in this surety environment is approaching to have
    results in 2022. 
  • In February,
    drugmaker Merck stopped its
    late-stage trial of verubecestat in patients with amiable to
    assuage Alzheimer’s, after a cabinet found that there was
    “virtually no possibility of anticipating a certain clinical
    effect.” The wish was to have the drug — a BACE inhibitor
    — stop the illness from progressing. Merck pronounced it’s still
    operative on another late-stage hearing for the drug to treat
    people with even progressing stages of the disease, and those
    results are approaching in 2019. 
  • Genentech has two Alzheimer’s drugs
    in late-stage development, despite hitting
    setbacks. In February, Genentech and its partner AC Immune
    launched a proviso 3 hearing for crenezumab,
    another drug that’s targeting amyloid deposits in the brain.
    It’s approaching to have information in 2020. The other is gantenerumab,
    a drug also targeting amyloid that unsuccessful progressing trials. The
    wish is that by
    augmenting the dose, it competence work. Genentech started a new
    proviso 3 hearing for gantenerumab in 2017.
