Genmab — Regulatory Filings 2016

Dec 20, 2016

Company Announcement

-- Regulatory application submitted in Japan for daratumumab for relapsed or
refractory multiple myeloma
-- Submission based on data from SIRIUS, CASTOR and POLLUX studies
-- Genmab to receive USD 10 million in milestone payments from Janssen –
financial guidance updated

Copenhagen, Denmark; December 20, 2016 – Genmab A/S (Nasdaq Copenhagen: GEN)
announced today that Janssen Pharmaceutical K.K. has submitted a New Drug
Application to the Ministry of Health, Labor and Welfare (MHLW) in Japan for
the use of daratumumab (DARZALEX®) for the treatment of adults with relapsed or
refractory multiple myeloma. The submission of the application triggers
milestone payments totaling USD 10 million to Genmab from Janssen. Genmab is
updating its financial guidance for 2016 to include the milestones. In August
2012, Genmab granted Janssen Biotech, Inc. an exclusive worldwide license to
develop, manufacture and commercialize daratumumab.

“We are pleased that the first regulatory application for daratumumab in the
Asia Pacific region has been submitted and look forward to the decision of the
Japanese regulatory authorities,” said Jan van de Winkel, Ph.D., Chief
Executive Officer of Genmab. “We continue to be excited by the potential of
daratumumab to make a positive impact on the lives of patients with multiple
myeloma and their families.”

The submission is built around three pivotal studies: the Phase II SIRIUS study
(MMY2002), published in The Lancet in April 2016; the Phase III CASTOR study
(MMY3004), published in The New England Journal of Medicine in August 2016; the
Phase III POLLUX study (MMY3003), published in The New England Journal of
Medicine in October 2016; and supported by several other studies.

OUTLOOK

MDKK Revised Guidance Previous Guidance

Revenue 1,720 – 1,770 1,650 – 1,700

Operating expenses (800) – (850) (800) – (850)

Operating income 895 – 945 825 – 875

Cash position at end of year* 3,650 – 3,750 3,650 – 3,750

*Cash, cash equivalents, and marketable securities

Genmab is improving its 2016 financial guidance published on November 21, 2016
due to the inclusion of daratumumab milestones totaling USD 10 million
associated with the submission of the regulatory application for daratumumab in
relapsed or refractory multiple myeloma in Japan.

Operating Result
We expect our 2016 revenue to be in the range of DKK 1,720 – 1,770 million, an
increase of DKK 70 million compared to the previous guidance. We have
increased our projected daratumumab milestones to DKK 1,090 million (previously
DKK 1,020 million) due to inclusion of USD 10 million in milestone payments
triggered by the submission of the regulatory application for daratumumab in
relapsed or refractory multiple myeloma in Japan. We expect DARZALEX royalties
to remain in the range of DKK 400 – 450 million, which are based on an
estimated USD 500 – 550 million of DARZALEX sales in 2016. The remainder of the
revenue mainly consists of Arzerra® royalties, DuoBody® milestones, and
non-cash amortization of deferred revenue.

We anticipate that our 2016 operating expenses will remain in the range of DKK
800 – 850 million.

As a result of the increased revenue, we now expect the operating income for
2016 to be approximately DKK 895 - 945 million, compared to DKK 825 - 875
million in the previous guidance.

Cash Position
There is no change to the cash position at the end of 2016 of DKK 3,650 - 3,750
million as we expect to receive payment for the additional milestones shortly
after year-end.

Outlook: Risks and Assumptions
In addition to factors already mentioned, the estimates above are subject to
change due to numerous reasons, including but not limited to the achievement of
certain milestones associated with our collaboration agreements; the timing and
variation of development activities (including activities carried out by our
collaboration partners) and related income and costs; DARZALEX and Arzerra
sales and corresponding royalties to Genmab; fluctuations in the value of our
marketable securities; and currency exchange rates. The financial guidance does
not include any potential proceeds from future warrant exercises and also
assumes that no significant agreements are entered into during 2016 that could
materially affect the results.

About multiple myeloma
Multiple myeloma is an incurable blood cancer that starts in the bone marrow
and is characterized by an excess proliferation of plasma cells.1 Multiple
myeloma is the third most common blood cancer in the U.S., after leukemia and
lymphoma.2 Approximately 30,330 new patients are expected to be diagnosed with
multiple myeloma and approximately 12,650 people are expected to die from the
disease in the U.S. in 2016.3 Globally, it was estimated that 124,225 people
would be diagnosed and 87,084 would die from the disease in 2015.4 While some
patients with multiple myeloma have no symptoms at all, most patients are
diagnosed due to symptoms which can include bone problems, low blood counts,
calcium elevation, kidney problems or infections.5 Patients who relapse after
treatment with standard therapies, including proteasome inhibitors or
immunomodulatory agents, have poor prognoses and few treatment options.6

About DARZALEX® (daratumumab)
DARZALEX® (daratumumab) injection for intravenous infusion is indicated in the
United States in combination with lenalidomide and dexamethasone, or bortezomib
and dexamethasone, for the treatment of patients with multiple myeloma who have
received at least one prior therapy and as a monotherapy for the treatment of
patients with multiple myeloma who have received at least three prior lines of
therapy, including a proteasome inhibitor (PI) and an immunomodulatory agent,
or who are double-refractory to a PI and an immunomodulatory agent.7 DARZALEX
is the first monoclonal antibody (mAb) to receive U.S. Food and Drug
Administration (FDA) approval to treat multiple myeloma. DARZALEX is indicated
in Europe for use as monotherapy for the treatment of adult patients with
relapsed and refractory multiple myeloma, whose prior therapy included a PI and
an immunomodulatory agent and who have demonstrated disease progression on the
last therapy. For more information, visit www.DARZALEX.com.

Daratumumab is a human IgG1k monoclonal antibody (mAb) that binds with high
affinity to the CD38 molecule, which is highly expressed on the surface of
multiple myeloma cells.

Daratumumab triggers a person’s own immune system to attack the cancer cells,
resulting in rapid tumor cell death through multiple immune-mediated mechanisms
of action and through immunomodulatory effects, in addition to direct tumor
cell death, via apoptosis (programmed cell death).7,8,9,10,11

Daratumumab is being developed by Janssen Biotech, Inc. under an exclusive
worldwide license to develop, manufacture and commercialize daratumumab from
Genmab. Five Phase III clinical studies with daratumumab in relapsed and
frontline multiple myeloma settings are currently ongoing, and additional
studies are ongoing or planned to assess its potential in other malignant and
pre-malignant diseases on which CD38 is expressed, such as smoldering myeloma,
non-Hodgkin’s lymphoma, NKT-cell lymphoma, amyloidosis, and solid tumors.
Daratumumab has received two Breakthrough Therapy Designations from the U.S.
FDA, for multiple myeloma, as both a monotherapy and in combination with other
therapies.
