Exdensur (depemokimab)
approved in China for the treatment of severe
asthma
● Exdensur is
the first and only ultra-long-acting biologic in China for the
treatment of severe asthma with an eosinophilic
phenotype
●
Approval based on
SWIFT trials showing significantly lower rates of exacerbations in
patients receiving depemokimab versus placebo
●
More than 2 million
people in China are affected by severe asthma and experience
increased risk of exacerbations requiring
hospitalisation
GSK plc (LSE/NYSE: GSK) today announced that China's National
Medical Products Administration (NMPA) has
approved Exdensur (depemokimab)
as add-on
maintenance treatment of severe asthma characterised by an
eosinophilic phenotype in adult and paediatric patients aged 12
years and older.
The approval of Exdensur in severe asthma is based on data from the
SWIFT-1 and SWIFT-2 phase III trials. In these studies, depemokimab
demonstrated sustained exacerbation reduction with two doses per
year versus placebo, both plus standard of care.1
Kaivan Khavandi, SVP, Global Head, Respiratory,
Immunology & Inflammation R&D, GSK,
said: "Today's
approval for Exdensur in China represents an important advance for
patients with severe asthma with an eosinophilic phenotype. By
providing sustained suppression of type 2 inflammation, an
underlying driver of exacerbations and disease
progression, Exdensur could redefine care in just two doses a
year. With Exdensur now approved in several major markets, we
are focused on transforming the treatment paradigm in severe
asthma."
Asthma is a major health burden in China affecting an estimated 46
million adults.2 Of
those, approximately 6% experience severe asthma, which is
associated with an increased risk of exacerbations requiring
hospitalisation, and higher likelihood of potentially fatal asthma
attacks.2-6 In
China, around 15% of people with asthma have experienced an
exacerbation requiring a hospital visit in the preceding 12
months.2
In the SWIFT-1 and SWIFT-2 trials, treatment with depemokimab
resulted in a significant 58% and 48% reduction in the rate of
annualised asthma exacerbations (asthma attacks) over 52 weeks,
respectively [rate ratio (95% confidence interval) p-value: SWIFT-1
0.42 (0.30, 0.59) p<0.001 and SWIFT-2 0.52 (0.36, 0.73)
p<0.001] (AER depemokimab versus placebo: SWIFT-1 0.46 vs. 1.11
and SWIFT-2 0.56 vs. 1.08 exacerbations per year). In addition,
efficacy and safety results from Chinese
patients participating
in SWIFT-1 were consistent with the overall
population analysis
(n=58).1
In a secondary endpoint from SWIFT-1 and SWIFT-2, patients treated
with depemokimab experienced numerically fewer exacerbations
requiring hospitalisation and/or emergency department visits (1%
and 4%) compared with placebo (8% and 10%), respectively. A
pre-specified pooled analysis of the two trials showed there was a
72% reduction in the annualised rate of clinically significant
exacerbations requiring hospitalisation and/or ED visits over 52
weeks for depemokimab compared with placebo [rate ratio 0.28, 95%
CI (0.13, 0.61), nominal p=0.002] (AER depemokimab 0.02 versus
placebo 0.09).1 Across
these trials, depemokimab was well-tolerated, with patients
experiencing a similar rate and severity of side effects as those
receiving placebo.1 The
full results from the SWIFT trials were presented at
the 2024 European
Respiratory Society International Conference and published in
the New
England Journal of Medicine.1,7
The NMPA
is also reviewing Exdensur as
an add-on therapy with intranasal corticosteroids for the treatment
of adult patients with severe chronic rhinosinusitis with nasal
polyps (CRSwNP) for whom therapy with systemic corticosteroids
and/or surgery does not provide adequate disease
control. Exdensur has
been approved in the US for the treatment of severe asthma, as well
as in Japan, the EU, and UK for the treatment of severe asthma and
CRSwNP.8-11
About asthma
Asthma affects more than 260 million people globally, many of whom
continue to experience symptoms and exacerbations despite
treatment.12,13 Severe
asthma is defined as asthma that requires treatment with medium- to
high-dose inhaled corticosteroids plus a second therapy (i.e.,
systemic corticosteroid or biologic) to prevent it from becoming
uncontrolled, or which remains uncontrolled despite
therapy.14 Type
2 inflammation is the underlying cause of pathology in more than
80% of patients with severe asthma, in which patients exhibit
elevated levels of eosinophils (a type of white blood
cell).14
About Exdensur (depemokimab)
Exdensur is
the first ultra-long-acting biologic being evaluated for certain
respiratory diseases with underlying type 2 inflammation. It
combines high interleukin-5 (IL-5) binding affinity and high
potency with an extended half-life to enable twice-yearly dosing.
IL-5 is a key cytokine in type 2 inflammation.1

About the SWIFT phase III trials
The SWIFT-1 and SWIFT-2 clinical trials assessed the efficacy and
safety of depemokimab adjunctive therapy in 382 and 380
participants with severe asthma who were randomised to receive
depemokimab or a placebo, respectively, in addition to their
standard of care (SOC) treatment with medium to high-dose inhaled
corticosteroids plus at least one additional controller. The full
analysis set in SWIFT-1 included 250 patients in the depemokimab
plus SOC arm and 132 in the placebo plus SOC arm; in SWIFT-2, 252
patients were included in the depemokimab plus SOC arm and 128 in
the placebo plus SOC arm.1
About the depemokimab development programme
Depemokimab is currently being evaluated in phase III trials for
the treatment of other diseases with underlying type 2
inflammation, including OCEAN for eosinophilic granulomatosis with
polyangiitis (EGPA) and DESTINY for hyper eosinophilic syndrome
(HES).15,16 GSK
has also initiated the ENDURA-1, ENDURA-2 and VIGILANT phase III
trials assessing the efficacy and safety of depemokimab as an
add-on therapy in patients with uncontrolled moderate to severe
COPD with type 2 inflammation.17-19
