ANNUAL REPORT 2021
The estimated annual incidence of systemic sclerosis is ap-
proximately 1.4 per 100,000 according to a new systematic
review
25
. The main cause of death in patients with systemic
sclerosis is interstitial lung disease and the medical need is
particularly high in these patients. The worth of the pharma-
ceutical market for systemic sclerosis was estimated to ap-
proximately USD 500 million in 2020 and is expected to grow
to USD 1.8 billion by 2030 in the seven major markets
26
. This
corresponds to an average annual growth rate of 14 percent.
Myocarditis is characterized by inflammation of the mus-
cular tissues of the heart (myocardium) arising from, for
example, various types of infections. Regardless of its eti-
ology, myocarditis is characterized by initial acute inflam-
mation that can progress to subacute and chronic stages,
resulting in tissue remodelling, fibrosis, and loss of myo-
cardium architecture and contractile function. The estimat-
ed incidence of myocarditis is about 22 per 100,000 (1.7
million)
27
, and globally the disease accounts for about 0.6
deaths per 100,000 (46,400) annually
28
. The medical need
is high for subgroups of patients with fulminant myocar-
ditis (acute disease) and dilated cardiomyopathy (chronic
disease), where mortality is very high in certain immune
subtypes. For these patients, heart transplantation is cur-
rently the only definitive treatment.
THE POTENTIAL OF NADUNOLIMAB FOR
COMBINATION WITH IMMUNOTHERAPY
AND OTHER CANCER TREATMENTS
With increasing knowledge of the immune system, there is
also a growing understanding of its ability to detect and kill
certain tumors. In the mid-1990s, it was recognized that
certain molecules could act as a brake, with capacity to in-
hibit activation of the immune system. Researchers estab-
lished that if this brake was released, the immune system
could be activated and subsequently attack the tumor. The
discoveries related to this function led to the development
of immunotherapies, in particular so-called checkpoint in-
hibitors. The first checkpoint inhibitor was approved by the
US FDA in 2011 for the treatment of melanoma.
Today, immunotherapies are also used to treat lung cancer,
kidney cancer, lymphoma, and skin cancer. Although im-
munotherapy has led to positive long-term effects in many
patients, a large number of patients still do not respond to
treatment. These therapies have also led to unexpected
side effects and some major clinical failures. It is not yet
known why the currently available immunotherapies only
show efficacy in some patients. Thus, there is still consider-
able scope for increasing the effectiveness of existing im-
munotherapies.
Performing treatments with a single drug at a time usu-
ally results in the targeting of only one signalling pathway
in the cancer cell, despite deregulation of several signalling
pathways as a consequence of the disease. This allows
the tumor to escape treatment, for example by activat-
ing and switching to alternative signalling pathways or by
further mutations which render the tumor less sensitive
to treatment. Combination therapies are thus regarded as
an important strategy, allowing for targeting of more than
one signalling pathway and resulting in durable treatment
responses. The downside is unfortunately that some com-
binations cause serious side effects. Future combination
therapies could, for example, include a combination of dif-
ferent immunotherapies, or of immunotherapies and more
traditional treatment forms such as chemotherapy, target-
ed drugs, and radiotherapy.
By combination of various therapies, it is also possible to
develop increasingly individualized treatment strategies
based on various characteristics of the individual’s immune
system and tumor. For this reason, extensive resources are
being devoted into research with the focus of increasing
our understanding of the relationship between various bio-
markers and the effect of treatments. This will contribute
to a better understanding of the types of treatments that
are suitable for each individual patient.
Cantargia operates in the borderland between immuno-
therapy and targeted treatments and is thus very much
involved in the effort of developing more effective treat-
ments that not only prolong the lives of patients but also
have the potential to cure the disease. In Cantargia’s stud-
ies, nadunolimab is combined with various established
treatments to improve treatment outcomes.
Among the new therapies that act by stimulating the im-
mune system to eliminate cancer cells, checkpoint inhibi-
tors, primarily the PD-(L)1 inhibitors, have had the great-
est impact on clinical use. The four immunotherapies that
have achieved the highest sales are Yervoy® (Bristol-Myers
Squibb), Opdivo® (BristolMyers Squibb), Keytruda® (Merck
& Co) and Tecentriq® (Roche). Together, the checkpoint
inhibitor market today is valued at approximately USD 25
billion. The largest PD-1 segments are non-small cell lung
cancer followed by melanoma and kidney cancer. Some of
the fastest growing indications for these drugs are small
cell lung cancer and bladder cancer where these drugs are
used in earlier treatment lines.
