Fixed-dose combination of albuterol and budesonide (PT027)
demonstrated significant benefits for asthma patients in MANDALA
and DENALI Phase III trials
9 September 2021 07:00 BST
Fixed-dose combination of albuterol and budesonide (PT027)
demonstrated significant benefits for asthma patients in MANDALA
and DENALI Phase III trials
PT027 significantly reduced the risk of severe exacerbations
compared to albuterol in patients with moderate to severe asthma in
MANDALA trial when used as a rescue medicine in response to
symptoms
PT027 significantly improved lung function compared to individual
components in mild to moderate asthma in DENALI trial
Positive high-level results from the MANDALA and DENALI Phase III
trials of PT027 (albuterol/budesonide), at both 180/160mcg and
180/80mcg doses, met all primary endpoints demonstrating
statistically significant benefits in patients with asthma
versus individual components albuterol, also known as
salbutamol (180mcg) and budesonide (160mcg).
PT027 is a potential first-in-class inhaled, fixed-dose
combination of albuterol, a short-acting beta2-agonist (SABA), and
budesonide, an inhaled corticosteroid (ICS), being developed by
AstraZeneca and Avillion.
The MANDALA trial met the primary endpoint, with PT027
demonstrating statistically significant and clinically meaningful
reductions in the risk of severe exacerbations compared to
albuterol, when used as a rescue medicine in response to
symptoms. The trial included 3,132 patients with moderate to severe
asthma taking maintenance ICS with or without additional controller
medicines.
The DENALI trial met the dual primary endpoints, with PT027 showing
a statistically significant improvement in lung function measured
by forced expiratory volume in one second (FEV1), compared to the
individual components albuterol and budesonide, and compared to
placebo. The trial included 1,001 patients with mild to moderate
asthma previously treated either with a SABA as needed alone or in
addition to low-dose maintenance ICS therapy.
Asthma is a chronic, inflammatory, fluctuating respiratory
disease1 that
affects as many as 339 million adults and children
worldwide,1 including
over 25 million in the US.2 Inflammation
is a distinctive feature of asthma3 and
plays a key role in asthma symptoms,4 exacerbations5 and
deaths.5
Bradley E. Chipps, Past President of the American College of
Allergy, Asthma & Immunology and Medical Director of Capital
Allergy & Respiratory Disease Center in Sacramento, US, said:
"Severe asthma exacerbations are a significant burden for
many asthma patients of all ages resulting in impaired quality
of life, hospitalisation, treatment with systemic corticosteroids
which can lead to serious side effects, and the possibility of
premature death. Many millions of patients globally rely on their
rescue inhaler to alleviate acute symptoms, but this does not treat
the underlying inflammation in asthma. The MANDALA and DENALI
trials demonstrate an albuterol/budesonide rescue inhaler can
address inflammation and prevent exacerbations, making PT027 an
important potential new treatment option for
patients."
Mene Pangalos, Executive Vice President, BioPharmaceuticals
R&D, said: "All patients with asthma are at risk of severe
exacerbations, regardless of their disease severity and many are
known to overuse short-acting bronchodilators. These exciting
results with PT027 bring us one step closer to providing
an innovative and superior treatment approach for asthma
by preventing exacerbations."
The safety and tolerability of PT027 in both trials were consistent
with the known profiles of the components. Detailed data from
MANDALA and DENALI will be presented at an upcoming medical
meeting.
Asthma
Patients with asthma experience recurrent breathlessness and
wheezing, which varies over time, and in severity and
frequency.4 These
patients are at risk of severe exacerbations regardless of their
disease severity, adherence to treatment or level of
control.6-7
There are an estimated 176 million asthma exacerbations globally
per year,8 including
more than 10 million in the US;2 these
are physically threatening and emotionally significant for many
patients9 and
can be fatal.1,4
Inflammation is central to both asthma symptoms4 and
exacerbations.5 Many
patients experiencing asthma symptoms use a SABA as a rescue
medicine, however, taking a SABA alone does not address
inflammation, leaving patients at risk of severe
exacerbations,10 which
can result in impaired quality of life,11 hospitalisation12 and
frequent oral corticosteroid (OCS) use.12 Repeated
courses of OCS therapy are associated with an increased risk of
systemic side effects including pneumonia, osteoporosis and type 2
diabetes.13,14 International
recommendations from the Global Initiative for Asthma no longer
recommend SABA as the preferred rescue therapy.4
MANDALA
MANDALA15,16 is
a Phase III, randomised, double-blind, multicentre, parallel-group,
event-driven trial evaluating the efficacy and safety of PT027
compared to albuterol on the time to first severe asthma
exacerbation in 3,132 adults and children aged four years and
older with moderate to severe asthma taking ICS alone or in
combination with a range of asthma maintenance therapies, including
long-acting beta2-agonists (LABA), leukotriene receptor antagonists
(LTRA), long-acting muscarinic antagonists (LAMA) or theophylline.
The trial comprised a two to four-week screening period, at least a
24-week treatment period and a two-week post-treatment follow-up
period.
Patients were randomly assigned to one of the following three
treatment groups in a 1:1:1 ratio: PT027 180/160mcg
(excluding patients aged 11 years or younger), PT027
180/80mcg or albuterol 180mcg, taken as a rescue medicine
in response to symptoms. PT027 and the albuterol comparator were
delivered in a pressurised metered-dose inhaler (pMDI) using
AstraZeneca's Aerosphere delivery technology. The primary efficacy
endpoint was the time to first severe asthma exacerbation during
the treatment period. Secondary endpoints included severe
exacerbation rate (annualised), total systemic corticosteroid
exposure over the treatment period, asthma control and
health-related quality of life.
DENALI
DENALI17,18 is
a Phase III, randomised, double-blind, placebo-controlled,
multicentre, parallel-group trial evaluating the efficacy and
safety of PT027 compared to its components albuterol and budesonide
on improvement in lung function in 1,001 adults and children aged
four years and older with mild to
moderate asthma previously treated either with SABA as
needed alone or in addition to regular low-dose ICS maintenance
therapy. The trial comprised a two-to-four-week screening period, a
12-week treatment period and a two-week post-treatment follow-up
period.
Patients were randomly assigned to one of the following five
treatment groups in a 1:1:1:1:1 ratio: PT027 180/160mcg four times
daily (excluding patients aged 11 years or younger), PT027
180/80mcg four times daily, albuterol 180mcg four times daily,
budesonide 160mcg four times daily and placebo four times
daily (excluding patients aged 11 years or
younger). PT027 and the albuterol and budesonide comparators
were delivered in a pMDI using
AstraZeneca's Aerosphere delivery technology. The dual primary
efficacy endpoints were a change from baseline in FEV1 area under
the curve 0-6 hours over
12 weeks of PT027 compared to budesonide to assess the effect of
albuterol and a change from baseline in trough FEV1 at
week 12 of PT027 compared to albuterol to assess the effect
of budesonide. Secondary endpoints included the time to onset and
duration of response on day one, number of patients who achieved a
clinically meaningful improvement in asthma control from baseline
at week 12 and trough FEV1 at week one.
PT027
PT027 is a potential first-in-class SABA/ICS rescue treatment
for asthma in the US, to be taken as needed in response to
symptoms. It is an inhaled, fixed-dose combination of albuterol
(also known as salbutamol), a SABA, and budesonide, a
corticosteroid, and is being developed in a pMDI using
AstraZeneca's Aerosphere delivery
technology.
AstraZeneca and Avillion collaboration
In March 2018, AstraZeneca and Avillion signed an agreement to
advance PT027 through a global clinical development programme for
the treatment of asthma. Under the terms of the agreement, Avillion
became the trial sponsor responsible for executing and funding the
multicentre, global clinical trial programme for PT027 through to
regulatory decision in the US. Following the successful approval of
PT027, AstraZeneca has the option, upon certain financial payments,
to commercialise the medicine in the US.
