Melanoma
is a Highly Heterogeneous Disease
Melanoma is a highly heterogeneous
disease comprising Cutaneous Melanoma (CM), Ocular Melanoma (OM), Mucosal
Melanoma (MM), melanoma of the internal organs, and, according to some
classifications, melanoma of the soft parts (non-bony and non-cartilaginous
tissues) of the body. CM is by far the most common form of melanoma, accounting
for approximately 90–95% of all melanomas; OM and MM account for approximately
3.7–5.2% and 1.3–1.4%, respectively, while melanomas of the internal organs and
soft parts are considered to be very rare, and their exact percentage distribution
is unknown (Chang et al., 1998; Jovanovic et al., 2013; Mihajlovic et al.,
2012; McLaughlin et al., 2005).
The main categories of melanoma can be
further sub-categorized into dozens of disease states with clinically distinct
subsets. The genomic landscapes, signaling pathways and immune checkpoints
(inhibitory immune system pathways that regulate the duration and amplitude of
physiological immune responses) that underlie this heterogeneity are extremely
complex. Melanoma is also characterized by significant intratumoral
heterogeneity as melanoma cells contain more gene mutations per cell than any
other type of cancer (Pimiento et al., 2013).
New
Drug Approvals in Recent Years Have Improved Treatment Options and Accelerated
Market Growth
Pharmacotherapy is primarily used to
treat patients with a high risk of disease recurrence following surgical
resection of the melanoma (adjuvant setting) or patients with unresectable or
metastatic melanoma (advanced setting). Traditionally, melanoma has been perceived
as a challenging disease to treat with pharmacotherapy, and treatment options
for patients have, until recently, been very limited.
However, in recent years, understanding
of the pathophysiology and heterogeneity of melanoma, and particularly CM, has developed
considerably. This has led to the approval of several new drug agents indicated
for CM since 2011, namely Sylatron (peginterferon alfa-2b) for the adjuvant CM
setting, and Yervoy (ipilimumab), Opdivo, (nivolumab), Keytruda
(pembrolizumab), Zelboraf (vemurafenib), Tafinlar (dabrafenib) and Mekinist
(trametinib) for the advanced CM setting. These have demonstrated superior
efficacy to previously marketed drugs, and have dramatically improved treatment
options for CM patients, leading to unprecedented market growth.
Growing Treatment Population, Increased
Uptake of Recently Approved Drugs and New Market Entrants to Ensure Pronounced
Market Growth throughout the Forecast Period
The treatment population is projected to
rise considerably by 2020, primarily as a result of rising CM incidence rates
and improved pharmacotherapy options. In particular, the continued uptake of
recent drug approvals, as well as new market entrants, will drive prolific
market growth throughout the forecast period. The melanoma pipeline is
currently strong, with several promising molecules in development including
Polynoma’s seviprotimut-L for adjuvant CM, AstraZeneca’s selumetinib for OM,
and Amgen’s talimogene laherparepvec (T-VEC) as well as Roche and Genentech’s
cobimetinib in combination with Zelboraf for advanced CM. Consequently, the
melanoma therapeutics market is projected to grow from $1.3 billion in 2013 to
$3.6 billion in 2020, at a CAGR of 15.4%, as shown in the following figure.
