NEW
YORK, July 8, 2024 /PRNewswire/ -- Woolsey
Pharmaceuticals, a clinical-stage drug development company,
announced that the first patient has started treatment at 300
mg/day in the REAL study, which is evaluating the effects of BRAVYL
in Amyotrophic Lateral Sclerosis (ALS).
As recently announced, participants treated with 180 mg/day
BRAVYL in the REAL study experienced a 15.5% decrease (improvement)
in NfL from baseline to 6 months (p<0.001). Since NfL in the ALS
population tends to increase by a mean of 11% in 6 months, this
suggests that 180 mg/day BRAVYL could potentially reduce NfL up to
26% versus a control group.
Moreover, greater decreases in NfL were correlated with less
deterioration on the ALSFRS-R (Spearman's coefficient = -0.45,
p=0.028) implying that early clinical benefits of reducing NfL may
be seen contemporaneously with the NfL reductions by BRAVYL.
A "propensity matched" analysis was performed wherein 12-month
clinical outcomes from REAL were compared with those from a matched
cohort selected by identifying 31 patients from the Ceftriaxone ALS
Study database that were most similar (based on pre-treatment age,
ALSFRS-R, time from onset of ALS, and other important parameters)
to each REAL patient.
The rate of deterioration in ALSFRS-R was improved in REAL vs.
the matched controls by 28% (p=0.12). REAL patients also had a 42%
(p=0.05) slower deterioration in SVC (breathing) and a 50% (p=0.06)
slower rate of muscle strength decline, driven mostly by lower limb
muscles with a 71% (p=0.04) reduction in weakening and a more
modest 37% (p=0.22) reduction in weakening of upper limb muscles.
An analysis that matched REAL patients recruited in Australia to the Australian MND Registry (a
longitudinal registry, not a study) yielded directionally similar
ALSFRS-R and SVC findings while muscle strength could not be
analyzed as the registry does not contain such data.
"The dosing of the first participant at 300 mg is another
important program milestone," notes Sven
Jacobson, CEO of Woolsey. "This next phase will allow us to
evaluate the safety and tolerability of a higher dose, in
preparation for our planned phase 2b
study. Our goal is to continue to advance development of BRAVYL for
people living with ALS, in hopes that we can slow the progression
of the disease and improve their quality of life."
ABOUT ALS
ALS is a fatal neurodegenerative disease characterized by
inevitable, and often rapid, decline in patients as the disorder
advances (mean survival time is only two to five years).
Accordingly, the ability to impede any worsening represents a
meaningful advancement in efforts to enhance the prognosis and
quality of life of individuals impacted by this devastating
condition.
