During the first quarter of 2019, revenue from collaborative and
licensing agreements was mainly composed of research services and
royalties.

As of March 31, 2019, government financing for research expenditures
mainly consisted of 25% of the research tax credit expected for 2019

the same period in 2018).

Cash, cash equivalents, available-for-sale financial assets and

Key achievements:

• Finance:
  • Transgene secured a €20 million revolving credit facility with
    a 30-month term with Natixis. Transgene will be able to draw
    on and repay the facility at its discretion. Transgene has used
    its shares in the Chinese biotech company Tasly Biopharmaceuticals
    as collateral for this loan (press release distributed on March
    18, 2019). As of May 13, 2019, the Company has not drawn down on
    this facility.
• Invir.IO™:
  • Transgene and AstraZeneca signed a collaborative research,
    option and exclusive license agreement to co-develop five armed
    oncolytic vaccinia virus candidates deriving from the
    Invir.IO™ platform.
    Transgene is to receive $10 million in Q2
    2019 and additional pre-clinical success milestones of up to $3
    million. Transgene is eligible to receive an option exercise
    payment on each candidate in the event AstraZeneca exercises one
    or more of its license option, as well as development and
    commercial milestones and royalties (press release distributed on
    May 2, 2019).
  • Transgene and BioInvent extend their collaboration to develop
    additional multifunctional oncolytic viruses encoding for
    antibodies capable of treating a broad range of solid tumors
    (press release distributed on March 26, 2019).
• myvac™:
  • Transgene announced that the NEOVIVA project, that is focused
    on Transgene’s individualized immunotherapy platform myvac™,
    was selected by the “Investments for the Future” Program
    (Programme d’Investissements d’Avenir) operated by Bpifrance.
    The NEOVIVA project will receive €5.2 million over the five-year
    duration of the program from Bpifrance, of which Transgene will
    receive €2.6 million (press release distributed on March 13, 2019).
• TG4050:
  • Transgene announced its decision to initiate clinical
    developments of its lead myvac™ candidate, TG4050, and
    the finalization of its collaboration agreement with NEC
    (press release distributed on March 5, 2019).
  • Transgene received FDA IND clearance for TG4050 to commence
    clinical development in ovarian cancer (press release distributed
    on May 13, 2019).

Outlook:

Transgene expects its cash burn for 2019 to be between €15 million and
€20 million, based on its current development plan and cash-in from the
collaboration with AstraZeneca.

As a result of the financing agreement with Natixis and the signing of
the collaboration with AstraZeneca, Transgene has extended its financial
visibility to Q4 2020.

Transgene confirms that it expects readouts from its key clinical trials
in the second half of 2019.
