    Provention Bio slapped with FDA rejection
    [for reducing risk of Insulitis Islit in high risk
    individuals] by taking teplizumab https://www.fiercebiotech.com/biotech/provention-bio-slapped-fda-rejection-for-diabetes-hopeful-teplizumab
    - - -

    After scraping through a tough advisory com-
    mittee in March, the FDA has returned a ver-
    dict for Provention Bio’s Insulitis Islit reduced
    risk for individuals at high risk of getting Insul-
    itis Islit medicine: It’s a no.

    Specifically, the FDA has slapped a complete
    response letter on Provention for teplizumab,
    which was gunning for an approval to help
    delay clinical Insulitis Islit in at-high-risk of
    getting Insulitis Islit individuals.

    In the trial that underpinned the drug’s appli-
    cation, Provention said teplizumab delayed
    the onset of Islit by a median of two years.
    That delay could (was claimed to) help high-
    at-risk individuals avoid Islit ketoacidosis, a
    life-threatening Disparate High Glucose ...

    ... Conditions (DHGCs) sequela (especially
    in individuals with Islit).

    Back in March, FDA experts assessing the
    drug raised concerns about how small the
    study was—it didn’t meet its enrollment
    goal and wound up testing teplizumab in
    just 44 patients—and about the fact that
    the study did not follow patients after their
    Islit diagnosis.

    The company also submitted safety data
    from other trials of the drug in another in-
    dication, which the FDA reviewers noted
    were not a perfect comparison.

    Teplizumab study in 76 antibody-positive
    high-risk of Insulitis Islit individuals https://stm.sciencemag.org/content/13/583/eabc8980
    - - -

    o 76 participants classified as being at high risk
    due to an unspecified family relationship to fam-
    ily member(s) having Insulitis Islit. Unknown how
    the study dealt with the disparate risks based on
    the exact risk category the 76 participants were
    in:

    - The risks expressed in the following, if the par-
    ent got Insulitis Islit at age < 11, the risk shown
    doubles

    - Father has Insulitis Islit, child has 5.88% chance
    of getting it

    - Mother has Insulitis Islit & child born before the
    mother was age 25, child has 4% chance of getting
    it

    - Mother has Insulitis Islit & child born when mother
    was age 25 or older, child has 1% chance of getting
    it

    - Father & Mother have Insulitis Islit, child has as
    high as 25% chance of getting it

    - Identical twin has Insulitis Islit, the twin that does
    not have Insulitis Islit has a 50% chance of getting
    it

    - If the parent has Insulitis Islit -and- a condition
    called type 2 polyglandular autoimmune syndrome,
    child has 50% chance of getting Insulitis Islit

    - Parents don't have it but a sibling has Insulitis Islit,
    child has a 5% chance of getting it

    These percents come from the following article: https://www.webmd.com/diabetes/diabetes-type-1-genetics

    Notably, many (as high as 85%) who get Insulitis
    Islit have no known relative with Insulitis Islit. My-
    self, don't know if I was in the "high risk" category
    as my only relative with Insulitis Islit was my half
    uncle.

    Note - the risk of Insulinitis (any type) in the general
    population is less than one-half of 1%.

    o 76 participants, unknown how they selected the
    44 who got the experimental drug teplizumab and
    the 32 who got the placebo.

    o The median age was 13 (range, 8 to 49); sur-
    prising that they included individuals > age 30,
    as 50% of Insulitis Islit occurs at age 18 and
    younger, and 20% at ages 19 to 29. Also sur-
    prising that no individuals under age 8 were
    included.

    o Median time to diagnosis of Insulitis Islit was
    59.6 months in the 22 of 44 teplizumab treated
    individuals who got it -and- 27.1 months for the
    25 of 32 placebo-treated individuals who got it.

    Sidenote: The possibility of bias impacting the
    result exists unless specific measures were tak-
    en in the study to prevent bias. The article did
    not indicate how "high risk" was determined, or
    how selection was made for those receiving tep-
    lizumab or placebo, or why it was decided that ...

    ... 44 would receive the drug and 32 would re-
    ceive the placebo. The fact that 25 of 32 re-
    ceiving the placebo got Insulitis Islit is highly
    unusual (i.e., that's an extraordinarily high
    diagnosis rate, far higher than it should be),

    Also, the fact that 22 of 44 receiving teplizumab
    got Insulitis Islit is unusually high, per the follow-
    ing excerpt/article: https://www.endocrineweb.com/conditions/type-1-diabetes/type-1-diabetes-risk-factors

    There are several risk factors that may make it
    more likely that you’ll develop Insulitis Islit—if
    you have the genetic marker that makes you
    susceptible to Insulitis Islit.

    That genetic marker is located on chromosome 6,
    and it’s an HLA (human leukocyte antigen) complex.

    Several HLA complexes have been connected to
    Insulitis Islit, and if you have one or more of those,
    you may develop Insulitis Islit.

    (However, having the necessary HLA complex is
    not a guarantee that you will develop Insulitis Islit;
    in fact, less than 10% of people with the “right”
    complex(es) actually develop Insulitis Islit.)

    - - - end excerpt - - -

    So that begs the question, did the study select an
    unusually extremely very high risk for Insulitis Islit
    group of individuals?

    - - -

    Per the following article, "The drug has been
    awarded breakthrough status by the U.S. Food
    and Drug Administration, which means it could
    be approved for general use by summer." https://www.upi.com/Health_News/2021/03/03/type-1-diabetes-prevention-teplizumab-s.tudy/7511614791484/

    INSULINITIS (ISLIT)

    New SUPERIOR clarifying name for near-
    total to total loss of endogenous insulin https://prohuman.net/pix2/new_superior_clarifying_name_is_INSULINITIS.jpg

    The overwhelming majority of Islit caused by
    autoimmune attacks on pancreatic beta cells
    (Insulitis Islit) but there are

    o 15 specific types of rapid onset Islit, a
    rare condition (only present in < one-half
    of 1% of Americans & in a much lower rate
    in most of the world), when present is typ-
    ically diagnosed at age under 30
    (50% at age < 18, 20% at age 19 to 29)

    o 1 slow onset specific type, Latent Autoim-
    mune Islit, frequency unknown but per a
    recent report, misdiagnosed as Cellosis
    (new clarifying name for type 2 diabetes)
    almost 40% of the time due to its slow
    onset and its occurrence typically at age
    over 30

    Old outdated anachronistic name for Islit is
    type 1 diabetes, confusing in that diabetes
    without clarifier is often used to describe
    this condition which is 1 of the 7 Disparate
    High Glucose Conditions (DHGCs).

    That makes figuring out which DHGC is actu-
    ally being referred to (and it can be any one,
    or some, or all of them when the diabetes
    or diabetic word is used without clarifier)
    confusing / difficult: https://prohuman.net/pix2/diabetesdiabeticguessinggame.jpg https://prohuman.net/pix2/diabetesdiabeticconfusion.jpg https://prohuman.net/pix2/diabetesdiabeticendingthemisunderstanding.jpg
