The situation does not take away from the important work our team is doing and we believe we can look forward to announcing exciting upcoming milestones in 2022.”

Update on Clinical and Preclinical Programs

CYAD-211 – Allogeneic shRNA-based, anti-BCMA CAR T candidate for r/r MM

• The dose-escalation, Phase 1 IMMUNICY-1 trial is evaluating the tolerability and clinical activity of a single infusion of CYAD-211 following preconditioning with CyFlu (cyclophosphamide and fludarabine) in patients with r/r MM.
  • At the 63rd American Society of Hematology (ASH) Annual Meeting and Exposition in December 2021, the Company presented the latest clinical data from the trial that showed a good tolerability profile and evidence of clinical activity. Data showed no dose-limiting toxicities, GvHD or CAR T-related encephalopathy syndrome (CRES). There was one Grade 1 cytokine release syndrome (CRS) event and three patients experienced Grade 3 or 4 treatment-related blood disorders. Three out of 12 total patients with r/r MM evaluated for activity achieved partial response, one in each dose-level, while eight patients had stable disease. All patients had detectable CYAD-211 cells in the peripheral blood, although engraftment was short lasting.
  • The next segment of the IMMUNICY-1 study will evaluate CYAD-211 following enhanced lymphodepleting (eLD) regimens with the aim to improve cell expansion and persistence and potentially maximize the clinical activity of CYAD-211. In addition, the IMMUNICY-1 protocol allows for redosing of CYAD-211 in certain patients.
  • Enrollment in the eLD cohorts of the IMMUNICY-1 trial is ongoing with additional data expected in the second half of 2022.

CYAD-101 – Allogeneic TIM-based, NKG2D CAR T Candidate for Metastatic Colorectal Cancer (mCRC).

• In December 2021, the Company announced the first patient was dosed in the Phase 1b CYAD-101-002 (KEYNOTE-B79) Phase 1b trial. The CYAD-101-002 trial is part of a collaboration with MSD, a tradename of Merck & Co., Inc., Kenilworth, NJ, USA, through a subsidiary. The trial is evaluating the Company’s TCR Inhibitory Molecule (TIM)-based allogeneic NKG2D CAR T cell investigational therapy, CYAD-101, administered concurrently with FOLFOX chemotherapy, followed by MSD’s anti-PD-1 therapy, KEYTRUDA® (pembrolizumab), in patients with refractory mCRC with microsatellite stable/mismatch-repair proficient disease.
• In February 2022, the Company voluntarily placed the Phase 1b trial on clinical hold after two fatalities occurred that presented with similar pulmonary findings. Subsequently, in March 2022, the U.S. Food & Drug Administration (FDA) put the Company on a clinical hold. The Company is currently investigating these findings and evaluating any similar events in additional patients treated on study. The Company expects to provide additional updates on the trial in the future.
• CYAD-101 is the only investigational candidate from the Company using the TIM technology.
  

CYAD-203 – Preclinical allogeneic shRNA-based, IL-18-armored NKG2D CAR T for Solid Tumors

• Preclinical data presented at the Society for Immunotherapy of Cancer (SITC) 36th Annual Meeting demonstrated enhanced anti-tumor activity of NKG2D CAR T cells when armored with the cytokine Interleukin-18 (IL-18), supporting the continued development of CYAD-203 as well as future allogeneic IL-18-armored CAR T candidates.
• IND-enabling studies are currently in progress alongside production of the clinical grade vector. Submission of the IND application to the FDA for CYAD-203 is anticipated by year-end 2022.

CYAD-02 – Autologous NKG2D receptor CAR T Candidate for relapsed or refractory Acute Myeloid Leukemia or Myelodysplastic Syndrome (r/r AML / MDS)

• At the ASH Annual Meeting and Exposition in December 2021, the Company presented the latest clinical data from the Phase 1 CYCLE-1 dose-escalation trial of CYAD-02 for the treatment of r/r AML / MDS.
  • Data from the trial showed that a single shRNA can target two independent genes (MICA/MICB) to enhance the phenotype of the CAR T cells. In addition, the dual knockdown of these genes showed a positive contribution to the initial clinical activity of CYAD-02 as well as a trend towards increased engraftment and persistence compared to our first-generation, autologous NKG2D receptor CAR T candidate, CYAD-01. A comparison of cellular kinetics for CYAD-02 and CYAD-01 trend towards increased engraftment and persistence of CYAD-02, potentially associated with the knockdown of MICA/MICB and reduced fratricide in vivo.

Upcoming Anticipated Milestones

• Enrollment in the cohorts evaluating enhanced lymphodepletion is ongoing in the CYAD-211 IMMUNICY-1 trial and additional data from the trial are expected in the second half of 2022.
• IND-enabling studies continue for CYAD-203, with submission of an IND application to the FDA for CYAD-203 anticipated by year-end 2022.

Full Year 2021 Financial Review

As of December 31, 2021, the Company had cash and cash equivalents of €30.0 million ($34.0 million).

Based on the Company’s current scope of activities, the Company estimates that its cash and cash equivalents as of December 31, 2021, combined with the remaining access to the equity purchase agreement established with Lincoln Park Capital Fund, LLC, should be sufficient to fund operating expenses and capital expenditure requirements until mid-2023.

Key financial figures for full-year 2021, compared with full-year 2020, are summarized below:

_{⁽¹⁾ “Treasury position” is an alternative performance measure determined by adding Short-term investments and Cash and cash equivalents from the statement of financial position prepared in accordance with IFRS. The purpose of this measure by Management is to identify the level of cash available internally (excluding external sources of financing) within 12 months.}

The Company’s license and collaboration agreements generated no revenue in 2021 and in 2020.

Research and Development (R&D) expenses were €20.8 million in 2021 as compared to €21.5 million in 2020, a year-over-year decrease of €0.7 million. The decrease in the Company’s R&D expenses is primarily driven by the Company’s decision to discontinue the development of CYAD-01 in the fourth quarter of 2020, as well as a decrease of the expenses associated with share-based payments (non-cash expenses) related to the warrant plan offered to our employees and directors.

General and Administrative (G&A) expenses were €9.9 million in 2021 as compared to €9.3 million in 2020, an increase of €0.6 million. This increase is primarily related to higher insurances costs and consulting fees partially compensated by the decrease of the expenses associated with the share-based payments (non-cash expenses) related to the warrants plan offered to our employees and directors.

The fair value adjustment (€0.8 million) relating to the contingent consideration and other financial liabilities as of December 31, 2021 was mainly driven by updated assumptions associated with the timing of the potential commercialization of the Company’s allogenic CYAD-101 CAR T program for mCRC and autologous CYAD-02 CAR T program for r/r AML/MDS as well as to reflect the future development of the program through potential partnership. The decrease of the liability is also driven by an update to the fair value measurement based on factors such as the weighted average cost of capital, the revaluation of the U.S. dollar against the Euro and updated assumptions on probability of success associated with the Company’s CAR T programs as of December 31, 2021.

The Company’s other income is associated with grants received from the Walloon Region mainly in the form of recoverable cash advances (RCAs) and R&D tax credit income:

• Grant income (RCAs): additional grant income has been recognized in 2021 on grants in the form of RCAs. According to IFRS standards, the Company has recognized grant income for the period amounting to €2.7 million and a liability component of €1.6 million is accounted for as a financial liability.
• Grant income (Others): additional grant income has been recognized in 2021 on grants received from the Federal Belgian Institute for Health Insurance Inami (€0.3 million) and from the regional government (for €1.1 million), not referring to RCAs and not subject to reimbursement.
• With respect to R&D tax credit, the current year income is predicated on a R&D tax credit recorded as (€0.7 million), which has been updated to take into account all information available as of this date and is in line with previous year.
  

In 2021, other income was partially compensated by other expenses including the remeasurement income on the RCAs of €0.3 million for the year 2021 and amendment fees associated with the Dartmouth license agreement signed in December 2021 for €1.1 million.

Net loss for the year ended December 31, 2021 was €26.5 million, or €1.70 per share, compared to a net loss of €17.2 million, or €1.23 per share, for the same period in 2020. As noted above, the increase in net loss between periods was primarily due to the decrease change in fair value of contingent consideration combined with the decrease on other income/expenses.

Net cash used in operations for the year ended December 31, 2021, which excludes non-cash effects, amounted to €26.6 million, which is in line with net cash used in operations of €27.7 million for the year ended December 31, 2020.
