Entry into a Material Definitive Agreement.
|
On December 7, 2020,
SELLAS Life Sciences Group, Inc. (“SELLAS”) and SLSG Limited, LLC, a wholly-owned subsidiary of SELLAS (“SLSG,”
and collectively with SELLAS, the “Company”), entered into an Exclusive License Agreement (the “License Agreement”)
with 3D Medicines Inc. (“3DMed”) pursuant to which the Company granted 3D Med a sublicensable, royalty-bearing license,
under certain intellectual property owned or controlled by the Company, to develop, manufacture and have manufactured, and commercialize
the Company’s galinpepimut-S (“GPS”) and heptavalent GPS (“GPS-Plus”) product candidates (the “Licensed
Products”), for all therapeutic and other diagnostic uses (the “Field”) in mainland China, Hong Kong, Macau
and Taiwan (the “Territory”). The license is exclusive, except with respect to certain know-how that has been non-exclusively
licensed to the Company and is sublicensed to 3DMed on a non-exclusive basis. The Company retains development, manufacturing and
commercialization rights with respect to the Licensed Products in the rest of the world.
In partial consideration
for the rights granted by the Company, 3DMed agreed to pay to the Company (i) a one-time upfront cash payment of $7.5 million
in order to reimburse the Company for certain expenses incurred with respect to the development of the Licensed Products prior
to execution of the License Agreement, and (ii) milestone payments totaling up to $194.5 million in the aggregate upon the achievement
of certain technology transfer, development and regulatory milestones, as well as certain net sales thresholds of Licensed Products
in the Territory in a given calendar year.
3DMed also agreed
to pay tiered royalties based upon a percentage of annual net sales of Licensed Products in the Territory ranging from the high
single digits to the low double digits. The royalties are payable on a Licensed Product-by-Licensed Product and region-by-region
basis commencing on the first commercial sale of a Licensed Product in a region and continuing until the latest of (i) the date
that is fifteen years from the receipt of marketing authorization for such Licensed Product in such region and (ii) the date that
is ten years from the expiration of the last valid claim of a licensed patent covering or claiming such Licensed Product in such
region (collectively, the “Royalty Term”). The royalty rate is subject to reduction under certain circumstances, including
when generic competition for a Licensed Product exists in a particular region.
3DMed is responsible
for all costs related to developing, obtaining regulatory approval of and commercializing the Licensed Products in the Field in
the Territory. 3DMed is required to use commercially reasonable best efforts to develop and obtain regulatory approval for, and
upon receipt of regulatory approval, commercialize the Licensed Products in the Field in the Territory. A joint development committee
will be established between the Company and 3DMed to coordinate and review the development, manufacturing and commercialization
plans with respect to the Licensed Products in the Territory. The Company and 3DMed also agreed to negotiate in good faith the
terms and conditions of a clinical supply agreement, a commercial supply agreement, and related quality agreements pursuant to
which the Company will manufacture or have manufactured and supply 3DMed with all quantities of the Licensed Product necessary
for 3DMed to develop and commercialize the Licensed Products in the Field in the Territory until 3DMed has received all approvals
required for 3DMed or its designated contract manufacturing organization to manufacture the Licensed Products in the Territory.
The License Agreement
will expire on a Licensed Product-by-Licensed Product and region-by-region basis on the date of the expiration of all of 3DMed’s
payment obligations to the Company. Upon expiration of the License Agreement, the license granted to 3DMed will become fully paid-up,
perpetual and irrevocable. Either party may terminate the License Agreement for the other party’s material breach following
a cure period or upon certain insolvency events. The Company may terminate the License Agreement if 3DMed or its affiliates or
sublicensees challenge the validity or enforceability of the licensed patents or if 3DMed fails to timely pay the upfront payment.
At any time following the two-year anniversary of the effective date, 3DMed has the right to terminate the License Agreement for
convenience, subject to certain requirements. 3DMed may terminate the License Agreement upon prior notice to the Company if the
grant of the license to 3DMed is prohibited or delayed for a period of time due to a change of United States export laws and regulations.
The License Agreement
includes customary representations and warranties, covenants and indemnification obligations for a transaction of this nature.
The foregoing description
of the terms of the License Agreement is not complete and is qualified in its entirety by reference to the full text of the License
Agreement, which the Company intends to file as an exhibit to one of the Company’s future filings with the U.S. Securities
and Exchange Commission.
