Novartis (Ofatumumab/Kesimpta)
Genmab and GlaxoSmithKline (GSK) entered a
co-development and collaboration agreement
for ofatumumab in 2006. The full rights to ofatu-
mumab were transferred from GSK to Novartis
in 2015. Novartis is now fully responsible for the
development and commercialization of ofatu-
mumab in all potential indications, including
autoimmune diseases. Genmab is entitled to a
10% royalty payment on net sales for non-cancer
treatments. Genmab pays a royalty to Medarex
based on Kesimpta net sales. Novartis’s obli-
gation to pay royalties to Genmab under this
agreement expire on a country-by-country basis
only in the event Novartis is no longer selling
such product in a given country. The royalties
are on a country-by-country basis subject to
reduction in case of significant competition
by competing products (as defined in the
agreement) or a joint committee determination
that a license of intellectual property owned by a
third-party is necessary for commercialization.
Roche (Teprotumumab/TEPEZZA)
In May 2001, Genmab entered a research
collaboration with Roche to develop human anti-
bodies to disease targets identified by Roche.
In 2002, this alliance was expanded. Under the
agreement, Genmab will receive milestones as
well as royalty payments on successful products.
Teprotumumab was initially developed in
collaboration between Genmab and Roche, and
later investigated under license from Roche
by River Vision Development Corporation
subsequently and Horizon Therapeutics for
ophthalmic use. The product was approved
under the brand name TEPEZZA in 2020 by the
U.S. FDA for the treatment of TED and in 2024
by Japan’s MHLW for the treatment of active
or high clinical activity score (CAS) TED. In
October 2023, Amgen completed its acquisition
of Horizon Therapeutics, including all rights
to the development and commercialization of
teprotumumab. Under the terms of Genmab’s
agreement with Roche, Genmab receives
a mid-single digit royalty on net sales of
TEPEZZA, on a country-by-country basis, for
10 years following the first commercial sale in
such country.
Pfizer (Tisotumab vedotin/Tivdak)
In September 2010, Genmab and Pfizer entered
into an ADC collaboration, and a commer-
cial license and collaboration agreement
was executed in October 2011. In October
2020, Genmab and Pfizer entered into a Joint
Commercialization Agreement where Genmab
would co-promote tisotumab vedotin, marketed
as Tivdak, in the U.S., and lead commercial
operational activities and record sales in Japan,
while Pfizer would lead operational commercial
activities in the U.S., Europe and China with a
50:50 profit split in those markets. In all other
markets, if any, Pfizer would be responsible for
commercializing tisotumab vedotin and Genmab
would receive royalties based on a percentage of
aggregate net sales ranging from the mid-teens
to the mid-twenties. Effective January 1, 2025,
Genmab and Pfizer agreed to amend the
License and Collaboration Agreement and the
Joint Commercialization Agreement for Tivdak,
assigning Genmab sole responsibility for the
development and commercialization of Tivdak for
second line plus recurrent or metastatic cervical
cancer in Europe and all other regions globally,
excluding the United States and the China region.
With this amendment, Genmab will continue to
co-promote Tivdak with Pfizer in the U.S. and
will record sales for Europe, Japan and rest of
world markets (excluding the United States and
China regions), once commercialized, and will
provide royalties to Pfizer on net sales in the low
teens. Pfizer will continue to lead commercial-
ization activities in China, when approved. The
companies will continue the practice of joint deci-
sion-making on the worldwide development and
commercialization strategy for tisotumab vedotin.
AbbVie (Epcoritamab/
EPKINLY/TEPKINLY)
On June 10, 2020, Genmab entered into a broad
oncology collaboration agreement with AbbVie
to jointly develop and commercialize products
including epcoritamab, and subsequently into a
discovery research collaboration for up to four
future differentiated antibody therapeutics for
cancer. The companies will share commercial
responsibilities for epcoritamab in the U.S. and
Japan, with AbbVie responsible for further global
commercialization. Genmab is the principal for
net sales in the U.S. and Japan and receives
tiered royalties between 22% and 26% on
remaining net sales outside of these territories,
subject to certain royalty reductions. For any
product candidates developed as a result of the
companies’ discovery research collaboration,
Genmab and AbbVie will share responsibilities
for global development and commercialization
in the U.S. and Japan. Genmab retains the right
to co- commercialize these products, along with
AbbVie, outside of the U.S. and Japan.
Under the terms of the agreement, Genmab
received a USD 750 million (DKK 4,911 million)
upfront payment in June 2020 and was initially
entitled to receive an aggregate of up to USD
3.15 billion in additional development, regulatory
and sales milestone payments for all programs.
Included in these potential milestones were up
to USD 1.15 billion in payments related to clinical
development and commercial success across
the three bispecific antibody programs originally
included in the agreement.
As a result of two programs being stopped,
Genmab is instead contractually entitled to
receive an aggregate of up to USD 2.55 billion
in additional development, regulatory and sales
milestone payments for all programs including an
aggregate of up to USD 550 million in payments
related to clinical development and commer-
cial success for the one remaining bispecific
antibody program, epcoritamab, included in
the original agreement. In addition, and also
included in these potential milestones, if all four
next- generation antibody product candidates
developed as a result of the discovery research
collaboration are successful, Genmab is eligible
to receive up to USD 2.0 billion in option exercise
and success-based milestones.
In May 2023, epcoritamab received initial
approval from the U.S. FDA and is marketed under
the tradename EPKINLY. In September 2023,
epcoritamab received initial approval from the
EC and the Japan MHLW and is marketed under
the tradenames TEPKINLY and EPKINLY, respec-
tively. Genmab is entitled to tiered royalties
between 22% and 26% on net sales for epcor-
itamab outside the U.S. and Japan. Except for
these royalty- bearing sales, Genmab will share
with AbbVie profits from the sale of licensed
products on a 50:50 basis. Genmab and AbbVie
split 50:50 the development costs related to
epcoritamab, while Genmab will be responsible
for 100% of the costs of the discovery research
programs up to opt-in.
The total transaction price of USD 750 million
(DKK 4,911 million) was allocated to the four
performance obligations based on the best
estimate of relative stand-alone selling prices.
