Mont-Saint-Guibert, Belgium – Celyad Oncology SA (Euronext & Nasdaq: CYAD), a clinical-stage biotechnology company focused on the discovery and development of chimeric antigen receptor T cell (CAR T) therapies for cancer (the Company), today announced its consolidated financial results for fiscal year 2020 ended December 31, 2020 and provided a business update.

“The past twelve months have proven to be an evolutionary period in our Company’s history, as we prioritized our resources for the advancement of our allogeneic portfolio and technology platforms. We believe the development of our differentiated non-gene edited allogeneic therapies to treat both solid tumors and hematological malignancies offers the biggest potential opportunity for patients and our shareholders by potentially expediting and expanding patient access to novel treatment options,” commented Filippo Petti, Chief Executive Officer of Celyad Oncology SA. “This past January, at the American Society of Clinical Oncology 2021 Gastrointestinal Cancers Symposium, we presented encouraging translational data from our ongoing alloSHRINK study, which complements the previously reported tolerability and clinical activity data for CYAD-101 in patients with advanced mCRC. Today, we are excited to disclose initial data from our lead shRNA-based allogeneic program CYAD-211 for relapsed/refractory multiple myeloma. As we look ahead, we expect a data rich calendar year with updates across all three of our clinical candidates as well as the start of the Phase 1b KEYNOTE-B79 trial, positioning 2021 to be a defining year for the advancement of our clinical pipeline.”

Recent Highlights

  • Entered into a committed equity purchase agreement for up to $40 million with Lincoln Park Capital Fund, LLC, a Chicago-based institutional investor
  • Appointed Marina Udier, Ph.D., a highly regarded leader in the biotechnology industry, to the Company’s Board of Directors

Update on Clinical and Preclinical Program

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

CYAD-211 is a first-in-class, allogeneic CAR T candidate engineered to co-express a BCMA-targeting chimeric antigen receptor and a single shRNA, which interferes with the expression of the CD3ζ component of the T-cell receptor (TCR) complex. In November 2020, the Company initiated the first-in-human, open-label, dose-escalation Phase 1 IMMUNICY-1 trial to evaluate the safety and efficacy of a single infusion of CYAD-211 following preconditioning chemotherapy cyclophosphamide and fludarabine in patients with relapsed/refractory (r/r) multiple myeloma (MM). The trial seeks to determine the recommended dose of CYAD-211 for the treatment of patients with r/r MM for further development as well as to establish proof-of-concept that single shRNA-mediated knockdown can generate allogeneic CAR T cells in humans without inducing Graft-versus-Host Disease (GvHD).

To date, no safety concerns or evidence of GvHD have been reported in the first three patients treated at dose level 1 (30×106 cells per infusion) of CYAD-211 in the IMMUNICY-1 trial. Enrollment in dose level 2 (100×106 cells per infusion) is currently ongoing.

CYAD-101 – Allogeneic TIM-based NKG2D CAR T for mCRC

The Company’s first-in-class, non-gene edited clinical candidate, CYAD-101, which co-expresses the NKG2D receptor and the novel inhibitory peptide TIM (TCR Inhibitory Molecule), continues to advance in the expansion segment of the alloSHRINK Phase 1 trial for the treatment of advanced metastatic colorectal cancer (mCRC). In January 2021, at the American Society of Clinical Oncology 2021 Gastrointestinal Cancers Symposium, the Company presented additional positive data from the alloSHRINK trial including median overall survival (mOS) of 10.6 months for the dose-escalation segment of the study as well as tumor burden decrease, according to RECIST 1.1 criteria, observed in eight of 15 patients, including six of nine patients at dose level 3. To our knowledge, CYAD-101 is the first investigational allogeneic CAR T candidate to generate evidence of clinical activity for the treatment of a solid tumor indication.

In December 2020, the Company initiated the expansion segment of the alloSHRINK trial, which is evaluating CYAD-101 following FOLFIRI (combination of 5-fluorouracil, leucovorin and irinotecan) preconditioning chemotherapy in refractory mCRC patients, at the recommended dose of one billion cells per infusion. The Company also plans to initiate the Phase 1b KEYNOTE-B79 trial, which will evaluate CYAD-101, following FOLFIRI preconditioning chemotherapy, with Merck’s PD-1 therapy, KEYTRUDA® (pembrolizumab), in refractory mCRC patients with microsatellite stable (MSS) / proficient mismatch repair (pMMR) disease. The Company believes the mechanism of actions of CYAD-101 and KEYTRUDA® are highly complementary and could help to drive additional clinical benefit in patients with advanced metastatic colorectal cancer.

CYAD-02 – Autologous NKG2D receptor-based CAR T for r/r AML and MDS

In November 2019, the Company initiated the dose-escalation Phase 1 CYCLE-1 trial, evaluating the safety and clinical activity of the next-generation, autologous NKG2D receptor-based CAR T candidate CYAD-02 following preconditioning chemotherapy in patients with relapsed/refractory acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS). The next-generation, NKG2D receptor-based CAR T candidate CYAD-02 incorporates a single shRNA to target the NKG2D ligands MICA and MICB.

To date, nine patients have received treatment with CYAD-02 in the CYCLE-1 trial. Treatment with CYAD-02 has been generally well-tolerated. Of seven patients evaluable for clinical activity, five patients demonstrated anti-leukemic activity (at least 50% bone marrow blasts decrease), including a very-high risk MDS patient treated at dose level 3 who achieved a marrow complete response, which is still ongoing. Enrollment in dose level 3 of the CYCLE-1 trial is currently ongoing.  

Next-generation shRNA Multiplex Platform

In 2020, the Company began developing a proprietary shRNA platform utilizing a novel framework to optimize and expand the expression of multiple shRNAs with our All-in-One Vector approach. Our novel framework has the capability to knockdown or silence up to six genes simultaneously, while providing several key advantages beyond our first-generation approach. We believe our next-generation shRNA multiplex platform will form the backbone for our future allogeneic CAR T candidates, including several programs which are in the discovery phase of development.

Upcoming Milestones

  • Additional proof-of-concept data from the initial dose cohorts of the Phase 1 IMMUNICY-1 trial of CYAD-211 for r/r MM are expected by the end of Q2 2021
  • Preliminary data from the expansion segment of the alloSHRINK trial evaluating CYAD-101 following FOLFIRI preconditioning chemotherapy in refractory mCRC patients are expected in Q2 2021
  • Initiation of the Phase 1b KEYNOTE-B79 trial evaluating CYAD-101 with KEYTRUDA® in mCRC patients with MSS/pMMR disease is anticipated by in the first half of 2021
  • Additional data from dose level 3 of Phase 1 CYCLE-1 trial of CYAD-02 for r/r AML and MDS are anticipated in the first half of 2021

Full Year 2020 Financial Results

As of December 31, 2020, the Company had a treasury position of approximately €17.2 million ($21.2 million).

On January 8, 2021, the Company entered into a committed equity purchase agreement (the Purchase Agreement) for up to $40 million with Lincoln Park Capital Fund, LLC (LPC), a Chicago-based institutional investor. Over the 24-month term of the Purchase Agreement, the Company will have the right to direct LPC to purchase up to an aggregate amount of $40 million American Depositary Shares (ADSs), each of which represents one of the ordinary shares of the Company. This equity facility is expected to strengthen the Company’s current statement of financial position while also providing the Company with access to future capital on an as needed basis and to ensure sufficient funding to cover its operations for the next 12 months from the date the financial statements are issued.

Based on the Company’s current scope of activities, the Company estimates that its cash and cash equivalents as of December 31, 2020 combined with the $40 million that the Company has access to from the equity purchase agreement established with LPC should be sufficient to fund operations until mid-2022.

Key financial figures for full-year 2020, compared with full-year 2019, are summarized below:

Selected key financial figures (€ millions)Full year 2020Full year 2019
Revenue                            –                              –  
Research and development expenses                    (21.5)                    (25.2)
General and administrative expenses                       (9.3)                       (9.1)
Change in fair value of contingent consideration                        9.2                         0.4
Other income/(expenses)                         4.6                         5.0
Operating loss                    (17.0)                    (28.9)
Loss for the period/year                   (17.2)                   (28.6)
Net cash used in operations                    (27.7)                    (28.2)
Treasury position(1)                      17.2                      39.3

(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 Company’s license and collaboration agreements generated no revenue in 2020 and in 2019.

The Research and Development (R&D) expenses show a year-over-year decrease of €3.7 million. The decrease is mainly driven by the decrease in preclinical activities, including process development and clinical development of the autologous programs associated with its r/r AML and MDS product candidates.

General and administrative expenses were €9.3 million in 2020 as compared to €9.1 million in 2019, an increase of €0.2 million. This increase primarily relates to higher insurances costs partly compensated by savings on the travel and living expenses due to COVID-19 pandemic travel restrictions.

The fair value adjustment (€9.2 million) relating to the contingent consideration and other financial liabilities as of December 31, 2020, mainly driven by updated assumptions associated with the timing of the potential commercialization of our autologous AML and MDS program as compared to year-end 2020. The decrease of the liability is also driven by the devaluation of the USD foreign exchange rate as of December 31, 2020.

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 2020 on grants in the form of recoverable cash advances (RCAs) for contracts, numbered 7685, 8087, 8088, 8212, 8436 and 1910028. According to IFRS standards, the Company has recognized grant income for the period amounting to €2.3 million and a liability component of €1.3 million accounted as a financial liability;
  • Grant income (Others): additional grant income has been recognized in 2020 on grants received from the Federal Belgian Institute for Health Insurance INAMI (€0.2 million) and from the regional government (contract numbered 8066 for €0.6 million), not referring to RCAs and not subject to reimbursement;
  • The remeasurement income on the RCAs of €0.9 million which is mainly related to the Company’s decision to update assumptions associated with the timing of the potential commercialization of our autologous AML and MDS program; and,
  • With respect to R&D tax credit, the decrease compared to 2020 is mainly related to a catch-up effect for €0.7 million which occurred in 2019 and a decrease on the current year income for €0.2 million due to global decrease on R&D expenses in 2020.

Net loss for the year ended December 31, 2020 was €17.2 million, or €1.23 per share, compared to a net loss of €28.6 million, or €2.29 per share, for the same period in 2019. The decrease in net loss between periods was primarily due to the increase change in fair value of contingent consideration combined with the decrease on the R&D expenses.

Net cash used in operations for the year ended December 31, 2020, which excludes non-cash effects, amounted to €27.7 million, which is in line with net cash used in operations of €28.2 million for the year ended December 31, 2019.

Annual Report 2020

The Annual Report for the year ended December 31, 2020 will be published tomorrow, March 25, 2021, and will be available on the Company’s website, www.celyad.com. The Company’s statutory auditor, EY Bedrijfsrevisoren BV/Reviseurs d’Entreprises SRL (EY), has confirmed that the completed audit has not revealed any material misstatement in the consolidated financial statements. EY also confirmed that the accounting data reported in the press release are consistent, in all material respects, with the consolidated financial statements from which it has been derived.

Letter from the Chairman

June 10, 2020 By Celyad

 “With Celyad Oncology, we are sharpening our efforts to one unified space and committing to a new vision that aligns with our Company’s passion: Eliminate Cancer. Improve Life.” 

Michel Lussier – Chairman 

Dear Shareholders, 

During the first half of 2020, Celyad and the rest of the world have had to face the far-reaching effects of the ongoing COVID-19 pandemic. I would like to thank the entire Celyad team, our investigators and other partners for being proactive in their efforts to protect the health and wellbeing of each other and our patients by practicing social distancing, working from home, and staggering shifts for essential employees when and where possible. 

The team’s commitment to developing our exciting pipeline of next-generation CAR T cell-based product candidates has allowed us to pursue our clinical efforts, including the continuation of several studies, as well as the initiation of new studies and cohorts for existing trials. In addition, the data and advancements we have made over the past year, has helped elevate our reputation as a leading CAR T company. 

Doubling Down on Strategic Focus with Celyad Oncology 

As such, we believe there is no better time to unveil our Company’s new name “Celyad Oncology”, which we believe more accurately reflects our commitment to cancer patients. With Celyad Oncology, we are sharpening our efforts to one unified space and committing to a new vision that aligns with our Company’s passion: Eliminate Cancer. Improve Life. 

Expertise in Allogeneic CAR T Therapy 

Over the past few years, we have made great progress with our NKG2D CAR T cell therapy programs, especially with our leading off-the-shelf candidate CYAD-101 for metastatic colorectal cancer. Specifically, the CYAD-101 alloSHRINK trial is the first study to evaluate a non-gene edited, allogeneic CAR T cell therapy candidate for the treatment of a solid cancer indication. 

At the 2020 American Society for Clinical Oncology (ASCO) Virtual Scientific Program, data from the dose-escalation Phase 1 alloSHRINK trial demonstrated continued encouraging clinical activity as well as an absence of graft-versus-host disease in fifteen metastatic colorectal cancer patients 

treated to date. These early results continue to support the differentiated profile of this off-the-shelf CAR T approach and we are excited about next steps for the program. 

At ASCO, we also reported for the first time that multiple genes can simultaneously be silenced using our short hairpin RNA (shRNA) technology in a CAR T construct. These results increase the potential for CAR T cells to be engineered with desired features that enhance anti-tumor activity. With the benefit of having two allogeneic platforms for CAR T development coupled with the foundational intellectual property we have in the field for allogeneic CAR T cells, I am encouraged by the prospects of our allogeneic CAR T franchise. 

Experienced Leadership in Oncology 

Along with these advances, we truly would not be the great team that we are without our employees and leadership team. We were excited to add Dr. Stephen Rubino as Chief Business Officer in March. This key hire is a forward-thinking move on our part as we look to the future in terms of business development and eventual commercialization. Moreover, we are thrilled that Dr. David Gilham will continue to steer the scientific endeavors of the organization in his new role as Chief Scientific Officer. Importantly, our Chief Executive Officer Filippo Petti officially joined the Board of Directors late last year as well. We also further strengthened our Board with the recent additions of Dr. Maria Koehler and Mr. Dominic Piscitelli. Both individuals bring a wealth of experience in the oncology space and we look forward to benefitting from their guidance as we advance our pipeline. 

Strong Path Forward to Success 

We anticipate a series of upcoming milestones throughout the course of 2020 that we believe will drive our clinical progress. These include the submission of an Investigational New Drug application for our first allogeneic shRNA-based CAR T candidate CYAD-211, beginning the expansion cohort of CYAD-101 alloSHRINK Phase 1 trial, and updated results from our autologous acute myeloid leukemia programs including data from both Phase 1 trials of CYAD-01 and preliminary data from the Phase 1 CYCLE-1 trial evaluating our next-generation autologous candidate CYAD-02. 

We are proud of our recent accomplishments and the potential for our current programs in the field of immuno-oncology. Looking ahead, we are just gearing up for far more opportunities and unlocking the true potential of our assets, technologies and intellectual property! 

I would like to personally express my gratitude towards our employees for their continued hard work and perseverance, and to all our shareholders for their support and excitement of Celyad Oncology. 

Michel Lussier 

Chairman of Celyad Oncology

Celyad Provides Update on Allogeneic CAR-T Franchise including CYAD-101 and shRNA Platform at the 2020 ASCO Virtual Scientific Program

June 1, 2020 By Celyad

  • First-in-class TIM-based non-gene edited allogeneic CAR-T candidate, CYAD-101, shows encouraging clinical activity with no evidence of graft-versus-host disease in relapsed/refractory metastatic colorectal cancer patients
  • Two patients achieved a confirmed partial response and nine patients achieved stable disease, leading to a disease control rate of 73%
  • Overall safety and clinical activity data are HLA-independent indicating that CYAD-101 cells can be used in a broad patient population regardless of the HLA haplotype
  • Expansion cohort of the alloSHRINK trial evaluating CYAD-101 following FOLFIRI preconditioning chemotherapy is expected to begin in the fourth quarter 2020
  • shRNA platform for next-generation allogeneic CAR-T candidates provides proof-of-principle to simultaneously knockdown up to four genes in a single construct
  • Management to hold a conference call on Monday, June 1st, at 2 p.m. CEST/ 8 a.m. EDT

Mont-Saint-Guibert, Belgium – Celyad (Euronext Brussels and Paris, and Nasdaq: CYAD), a clinical-stage biopharmaceutical company focused on the development of CAR-T cell therapies, today announced updates from the company’s allogeneic programs, including additional data from the Phase 1 alloSHRINK trial evaluating the T cell receptor (TCR) inhibitory molecule (TIM)-based, non-gene edited allogeneic CAR-T  candidate, CYAD‑101, for the treatment of metastatic colorectal cancer (mCRC), and the company’s short hairpin RNA (shRNA) platform underpinning the next-generation, non-gene edited CYAD-200 series of CAR-T candidates. These data were presented at the 2020 American Society of Clinical Oncology (ASCO) Virtual Scientific Program from May 29-31, 2020.

Dr. Frédéric Lehmann, VP of Clinical Development at Celyad, commented, “The latest safety and clinical activity data from the alloSHRINK trial in metastatic colorectal cancer patients further demonstrate CYAD-101’s differentiated profile as an allogeneic CAR-T candidate. The absence of clinical evidence of graft-versus-host-disease (GvHD) for CYAD-101, which co-expresses the NKG2D receptor with our novel, TIM technology used to knockdown signalling of the TCR complex, confirms the potential of non-gene edited approaches for the development of allogeneic CAR-T  candidates. Taking these positive clinical data into account, we have decided to broaden the program to include evaluating CYAD-101 following FOLFIRI chemotherapy in refractory patients as an expansion cohort of the alloSHRINK trial. Overall, treatment of advanced metastatic colorectal cancer patients beyond second line regimens remains a high unmet medical need, and we believe CYAD-101 could offer a unique immunotherapeutic approach to treat this incurable disease.”

Dr. David Gilham, CSO of Celyad, stated, “CYAD-101 has pioneered the potential for non-gene edited approaches for the development of allogeneic CAR-T  candidates, and we are excited to build upon this strong position with our shRNA technology platform. Preclinical data reported during ASCO over the past few days confirm the ability of a single shRNA hairpin to provide prolonged TCR knockdown, which our first shRNA-based allogeneic candidate, CYAD-211. In addition, the data demonstrated the breadth and depth of the shRNA platform, including the concurrent knockdown of up to four genes. We believe combining the knockdown potential of the platform with additional construct enhancements provides tremendous therapeutic optionality to our non-gene edited CYAD-200 series of CAR-T candidates.”

alloSHRINK Phase 1 Trial Update
Background
  • To date, a total of 15 patients with relapsed/refractory mCRC who progressed after previous treatment with oxaliplatin-based or irinotecan-based chemotherapies have been enrolled in the dose-escalation, alloSHRINK Phase 1 trial evaluating three consecutive dose levels of CYAD-101 administered concurrently with FOLFOX chemotherapy. The number of prior therapies received by patients enrolled in the trial ranged from one to six with a mean of three.
  • All 15 patients were dosed from a single cell bank of CYAD-101 that was generated in advance from two manufacturing runs each using a fraction of an apheresis from a single healthy donor.

Safety and Tolerability

  • No clinical evidence of GvHD has been observed following 44 injections of CYAD-101. We believe these data continue to support the ability of the company’s novel inhibitory peptide TIM to reduce signaling of the TCR complex through a non-gene edited approach.
  • Treatment with CYAD-101 following FOLFOX preconditioning chemotherapy was observed to be well-tolerated. Seven of the 15 patients enrolled in the trial reported at least one treatment-related adverse event (AE), however, all AEs reported were grade 1 or 2, including one patient who experienced cytokine-release syndrome (grade 1). No patient discontinued treatment due to AEs.

Clinical Activity

  • Encouraging anti-tumor activity was observed in the trial with two patients who achieved a confirmed partial response (PR) according to RECIST 1.1 criteria, including one patient with a KRAS-mutation, the most common oncogenic alteration found in all human cancers. In addition, nine patients achieved stable disease (SD), with seven patients demonstrating disease stabilization lasting more than or equal to three months of duration.
  • No correlation was observed between clinical responses and the degree of human leukocyte antigen (HLA) matching between patients and CYAD-101 donor cells, indicating that CYAD-101 can be used in a broad patient population regardless of the HLA haplotype.

Next Steps

  • An expansion cohort of alloSHRINK trial will evaluate CYAD-101 following FOLFIRI (combination of 5-fluorouracil, leucovorin and irinotecan) preconditioning chemotherapy in refractory mCRC patients, at the recommended dose of one billion cells per infusion. Enrollment in the expansion cohort of the trial is expected to begin during the fourth quarter of 2020.
shRNA Platform and CYAD-200 Series
Background
  • In October 2018, the company announced an exclusive agreement with Horizon Discovery Group for the use of its shRNA technology to generate a novel, next-generation, non-gene-edited allogeneic platform for CAR‑T therapies. Horizon Discovery’s SMARTvector technology to express shRNA was optimized by Celyad to knockdown the TCR complex in allogeneic CAR-T therapies as well as to target a broad range of proteins.

shRNA Platform

  • shRNA platform coupled with company’s all-in-one vector approach is designed to provide flexibility, versatility and efficiency in designing novel, allogeneic CAR-T candidates through single step engineering process.
  • Lead shRNA-based allogeneic candidate CYAD-211, targeting B-cell maturation antigen (BCMA) for the treatment of relapsed/refractory multiple myeloma, which uses a single hairpin to knockdown the CD3ζ component of the TCR complex, is expected to enter clinical trials by year-end 2020.
  • Next-generation candidates exploring two shRNA knockdowns are currently under development.
  • Continued preclinical evaluation of the shRNA platform demonstrates proof-of-principle that the concurrent knockdown of four genes using an optimized framework is feasible.
  • Combining shRNA knockdown with additional functional components should offer therapeutic optionality to non-gene edited allogeneic CYAD-200 series of product candidates.
Conference Call and Webcast Details
Celyad will host a conference call to discuss the update from ASCO on Monday, June 1, 2020 at 2 p.m. CEST / 8 a.m. EDT. The conference call can be accessed through the following numbers:

About CYAD-101 and alloSHRINK Trial

CYAD-101 is an investigational, non-gene edited, allogeneic (healthy donor derived) CAR-T  candidate engineered to co-express a chimeric antigen receptor based on NKG2D, a receptor expressed on natural killer (NK) cells that binds to eight stress-induced ligands and the novel inhibitory peptide TIM (TCR Inhibitory Molecule). The expression of TIM reduces signalling of the TCR complex, which is responsible for graft-versus host disease.

alloSHRINK is an open-label, dose-escalation Phase 1 trial assessing the safety and clinical activity of three consecutive administrations of CYAD-101 every two weeks administered concurrently with FOLFOX (combination of 5-fluorouracil, leucovorin and oxaliplatin) chemotherapy in patients with refractory mCRC. In the expansion cohort of the trial, CYAD-101 will be administered concurrently with FOLFIRI.

About shRNA Platform and CYAD-200 Series

The company is focused on the development of its proprietary non-gene edited allogeneic short hairpin RNA (shRNA) SMARTvector technology platform through the CYAD-200 series of candidates. The company is currently evaluating several shRNA-based allogeneic CAR-T candidates, including CYAD-211, an allogeneic CAR-T candidate targeting B-cell maturation antigen for the treatment of relapsed/refractory multiple myeloma.

About Colorectal Cancer

Colorectal cancer is the third most common type of cancer among both men and women worldwide and is the fourth most common in terms of mortality. In 2018, approximately 1.8 million people were diagnosed with colorectal cancer, with about 140,000 and 500,000 diagnoses in the United States and Europe, respectively. According to data from ASCO, approximately 40% of patients are diagnosed with early-stage, localized-stage disease. The five-year survival rate of localized disease is approximately 90%. In patients where the cancer has spread to distant parts of the body, as in metastatic colorectal cancer, the five-year survival rate drops to approximately 15%.

Celyad Announces First Quarter 2020 Financial Results and Recent Business Highlights

May 7, 2020 By Celyad

Mont-Saint-Guibert, Belgium – Celyad (Euronext Brussels and Paris, and Nasdaq: CYAD), a clinical-stage biopharmaceutical company focused on the development of CAR-T cell therapies, today announced an update on operational developments for the first quarter ended March 31, 2020.

“I am extremely proud of our team’s dedication and focus over the past few months in progressing the development of our exciting CAR-T therapies during the COVID-19 pandemic. As a result of their efforts, we’ve continued to advance our programs, bringing us closer to several key milestones associated with our clinical and preclinical programs over the course of 2020. Specifically, we anticipate announcing additional data from our CYAD-101 alloSHRINK Phase 1 trial at ASCO, and filing the IND application for our lead shRNA-based allogeneic candidate CYAD-211 over the next few months, as well as providing a clinical update on our relpased/refractory AML and MDS program in the second half of the year,” commented Filippo Petti, CEO of Celyad.

First Quarter 2020 and Recent Business Updates

  • Initiation of the Phase 1 CYCLE-1 trial evaluating the next-generation autologous NKG2D receptor CAR-T candidate, CYAD-02, for the treatment of relapsed/refractory (r/r) acute myeloid leukemia (AML) and myleodysplastic syndromes (MDS);
  • Appointment of Dr. Stephen Rubino as Chief Business Officer as part of the strategic evolution of the management team;
  • Appointment of Dr. Maria Koehler and Mr. Dominic Piscitelli to Board of Directors;
  • Scheduled to present an update on the allogeneic NKG2D receptor CAR-T candidate, CYAD-101, for the treatment of refractory metastatic colorectal cancer (mCRC) at 2020 American Society of Clinical Oncology (ASCO) Virtual Scientific Program on May 29 – 31.

First Quarter 2020 Financial Review

The Company ended first quarter 2020 with a treasury position of €33.8 million ($37.3 million). Net cash burn over the first quarter of 2020 amounted to €5.5 million, which is in line with expectations. The Company confirms its previous guidance that its treasury position should be sufficient to fund operating expenses and capital expenditure requirements, based on the current scope of activities,  through first half 2021.

Update on Clinical and Preclinical Programs

CYAD-01 – Autologous NKG2D CAR-T for r/r AML and MDS

The Company’s first-in-class NKG2D CAR-T clinical candidate CYAD-01 continues to advance in Phase 1 trials for the treatment of patients with r/r AML and MDS. During the first quarter of 2020, the Company began recruitment within the expansion cohort of the Phase 1 THINK trial evaluating monotherapy CYAD-01. As reported in March 2020, the Company expects to announce preliminary data from CYAD-01 produced with OptimAb manufacturing process, including the expansion cohort of the Phase 1 THINK trial and the dose-escalation Phase 1 DEPLETHINK trial in the second half of 2020.


CYAD-02 – Autologous NKG2D CAR-T for r/r AML and MDS

In January 2020, the Company announced the first patient was dosed in the Phase 1 dose-escalation CYCLE-1 trial evaluating CYAD-02 for the treatment of r/r AML and MDS. In April, the Company began enrollment in the second dose cohort of the trial. The CYCLE-1 trial is assessing the safety and clinical activity of a single infusion of CYAD-02 produced with the OptimAb manufacturing process following preconditioning chemotherapy with cyclophosphamide and fludarabine.

CYAD-101 – Allogeneic TIM-based, NKG2D CAR-T for mCRC

The Company’s allogeneic clinical candidate, CYAD-101, which incorporates the non-gene edited T-cell receptor inhibitory molecule (TIM) technology, continues to advance in the Phase 1 alloSHRINK trial. Preliminary data to date has demonstrated no evidence of graft-versus-host disease (GvHD), no dose-limiting toxicity and promising early signals of clinical activity. Based on the initial data, the Company plans to progress to an expansion cohort of the trial to further evaluate CYAD-101 in refractory mCRC patients. The Company expects to report additional data from the dose-escalation segment of the CYAD-101 alloSHRINK Phase 1 trial at the 2020 ASCO Virtual Scientific Program on May 29 – 31.
