Steady progress in THINK




and LINK



Regulatory News:

Celyad (Euronext Brussels and Paris, and NASDAQ: CYAD) (Paris:CYAD)
(Brussels:CYAD) a clinical-stage biopharmaceutical company focused on
the development of specialized CAR-T cell based therapies, today
provided an update on key clinical and operational developments for the
first quarter ended March 31, 2018.


  • Robust clinical development plan is foundation for new trials focusing
    on AML and CRC

  • Steady progress related to ongoing THINK, SHRINK and LINK trials

  • Good safety profile of CYAD-01 confirmed

  • Lead publication Haematologica publishes THINK Study Case Report

Dr. Christian Homsy, CEO of Celyad commented: “We had a
productive first quarter, further defining our strategy that will guide
CYAD-01 in becoming the foundation for cancer therapies. Not only have
we progressed in the THINK trial, we have also treated our first
patients in the SHRINK and LINK trial. The absence of any observed
critical on target/off tumor toxicity in our trials is an important
signal validating our technology. The next months will be exciting for
our company and we look forward communicating results on our clinical
trials in scientific congresses.”


In February 2018, Celyad provided a detailed clinical update summarizing
the promising results achieved in 2017: the THINK trial resulted in
signs of clinical activity ranging from Stable Disease (SD) to Complete
Response (CR), despite the absence of preconditioning therapy and the
lower doses used at that stage of the trial. The company also announced
that it will further evaluate CYAD-01 in a series of additional Phase 1
clinical trials in patients with AML and CRC.

Also in February 2018, Celyad organized a Key Opinion Leader meeting on
CAR-T therapy in New York, USA. The meeting featured a presentation by
Marco Davila, MD, PhD (Moffitt Cancer Center). The numerous attendants
received information on the unmet medical need in blood cancers as well
as details on Celyad’s clinical strategy.

On the operation side, during this first quarter, Celyad progressed well
in the THINK trial as well as the in LINK trial:

- The company dosed the three CRC patients in the third dose cohort in
the solid arm of the THINK trial, and the two last AML patients in the
second dose. Celyad plans to initiate the third dose in the AML arm in
May 2018, and complete the recruitement of three additional CRC patients
at the higher dose by mid-2018. In 2018, all patients were dosed with
the our new production process adopted in December 2017.

- The company also treated its first CRC patient in the LINK trial. This
patient received three planned injections at the first Dose level (3x108).
LINK adopts a loco-regional approach in treating CRC by administering
CYAD-01 through multiple hepatic transarterial injections.

The company ended the quarter with €25.1 million in cash, cash
equivalents and short-term investrments. Use of cash over the first
quarter of 2018 amounted to €8.8 million, in line with expectations. The
company confirms that existing cash and cash equivalents and short term
investments are sufficient to fund operating expenses and capital
expenditure requirements, based on the current scope of activities,
until the end of Q1 2019.


In April 2018, Celyad’s world’s first reported complete response by a
CAR-T cell therapy in a patient with refractory and relapsed AML was
published as a case report in the leading scientific publication Haematologica.
The publication detailed the first objective response related to this
patient that is still in remission, more than 9 months after study

In May 2018, Celyad achieved an important milestone in its CYAD-01
clinical strategy by dosing the first metastatic CRC patients in the
LINK and SHRINK trials. No drug related toxicity was observed in the
first patients of both SHRINK and LINK trials.

Generally, Celyad’s progress is the result of the company’s clinical
development plan aiming at defining the best of three approaches for
CYAD-01 in patients with AML and CRC:

1) CYAD-01 as a stand-alone investigational therapy, currently being
evaluated in the THINK trial with relapsed refractory AML and CRC
patients. Promising results have already been reported including a
complete response and stable diseases.

Based on data as of April 5, 2018, the date of Celyad’s most recent
interim safety report for the THINK trial, Celyad had collected safety
data from 20 patients treated with CYAD-01 in the THINK trial. Of the 20
patients included in the interim safety report of the THINK trial (11
solid and nine hematologic cancer patients), Celyad reported the
following serious adverse events:

  • Grade 4 serious adverse events occurred in two patients: one patient
    in the hematologic cohort experienced respiratory failure and other
    Grade 4 adverse events after administration of dose level one of
    CYAD-01. The other patient, who was in the solid tumor cohort,
    experienced cytokine release syndrome and other Grade 4 adverse events
    after administration of dose level three of CYAD-01, which was
    adjudicated as a dose limiting toxicity (DLT).

  • Those two patients each experienced a Grade 5 event that was deemed
    unrelated to administration of CYAD-01.

2) CYAD-01 administered concurrently with standard of care treatments.
The SHRINK trial was recently initiated with the dosage of one CRC
patient in April 2018. No Grade 4 or higher adverse event has been
reported so far. This trial evaluates the concurrent administration of
CYAD-01 with the standard chemotherapy FOLFOX. We expect that another
similar trial aimed at AML patients, EPITHINK trial, will be initiated

3) CYAD-01 administered after preconditioning of the patients using
lymphodepletion. We expect trials in AML (DEPLETHINK AML) and CRC
(DEPLETHINK CRC) patients to be initiated in the coming weeks.
