MONT-SAINT-GUIBERT, Belgium, Nov. 10, 2021 (GLOBE NEWSWIRE) -- Celyad Oncology SA (Euronext & Nasdaq: CYAD) (the “Company”), a clinical-stage biotechnology company focused on the discovery and development of chimeric antigen receptor T cell (CAR T) therapies for cancer, today announced an update on its financial results and recent business developments for the fiscal quarter ended September 30, 2021.

"Our team continues to take major strides towards the development of a differentiated, next-generation CAR T pipeline based on novel non-gene edited technologies which we believe offer potential advantages over gene-editing approaches. During our R&D Day in the third quarter, we provided an in-depth review of our platforms, including our proprietary shRNA and TIM technologies, as well as our ‘armored’ CAR franchise focused on the co-expression of secreting IL-18. These key capabilities are reflected across our allogeneic clinical programs and highlight the advancements we’re making. Overall, we’ve treated more than 30 patients with our allogeneic CAR T product candidates without evidence of GvHD while observing encouraging early signals of clinical activity, which we believe is a promising validation that our non-gene edited strategy for allogeneic CAR T has the potential to be a game-changer for the field,” commented Filippo Petti, Chief Executive Officer of Celyad Oncology. “There are several data readouts scheduled at this year’s ASH and SITC annual meetings, and we believe the updates from the Phase 1 IMMUNICY-1 trial of CYAD-211, as well as the pending initiation of the Phase 1b KEYNOTE-B79 trial will further position us as leaders in the allogeneic CAR T space.”

Recent Highlights

• Research & Development Day held on July 20, 2021, during which the management team provided:
  • Updates on the allogeneic CAR T clinical candidates CYAD-211 and CYAD-101.
  • Highlights from the latest research from the Company’s proprietary short hairpin RNA (shRNA) platform, including the introduction of CYAD-203 – a novel allogeneic, Interleukin-18 (IL-18)-armored CAR T candidate currently in IND-enabling studies.
• Acquisition of an exclusive patent license from the University of Pennsylvania for an engager targeting Glypican 3 (GPC3), which will be tested with the Company’s proprietary shRNA technology platform.
• Three abstracts to be presented at the Society for Immunotherapy of Cancer (SITC) 36^th Annual Meeting, which will include information about:
  • Celyad Oncology’s multiplexing capabilities using shRNA technology.
  • The Company’s first non-gene edited allogeneic, IL-18-armored CAR T candidate CYAD-203.
  • Phase 1b KEYNOTE-B79 trial of CYAD-101 followed by KEYTRUDA^® (pembrolizumab) in refractory metastatic colorectal cancer patients.
• Two abstracts to be presented at the 63^rd ASH Annual Meeting to be held from December 11-14, 2021, which will include additional data for CYAD-211 and CYAD-02.
  

Third Quarter 2021 Financial Review
As of September 30, 2021, the Company had cash and cash equivalents of €6.1 million ($7.1 million), representing a decrease in cash and cash equivalents of €5.9 million as compared to June 30, 2021. The Company believes that its existing cash and cash equivalents combined with the remaining access to the equity purchase agreement established with Lincoln Park Capital Fund, LLC should be sufficient, based on the current scope of activities, to fund operating expenses and capital expenditure requirements to the end of the third quarter of 2022.

Update on Clinical and Preclinical Programs

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

• CYAD-101 is the Company’s allogeneic CAR T candidate engineered to co-express a chimeric antigen receptor (CAR) based on the NKG2D receptor and the novel inhibitory peptide TCR Inhibitory Molecule (TIM).
• To the Company’s 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.
• The Phase 1b KEYNOTE-B79 trial, which will evaluate CYAD-101 following FOLFOX preconditioning chemotherapy, with MSD’s anti-PD-1 therapy, KEYTRUDA^® (pembrolizumab) in refractory mCRC patients with microsatellite stable (MSS) / mismatch-repair proficient (pMMR) disease, is on track to begin by year-end 2021.
• This KEYNOTE-B79 trial is part of a clinical trial collaboration involving Celyad Oncology and MSD, a tradename of Merck & Co., Inc., Kenilworth, NJ., USA, through a subsidiary.

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

• CYAD-211 comprises a B cell maturation antigen (BCMA) targeting CAR co-expressed with a shRNA that targets the CD3ζ component of the T-cell receptor (TCR) complex.
• 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 cyclophosphamide and fludarabine given for three consecutive days.
• In July 2021, preliminary data from the Phase 1 IMMUNICY-1 trial was presented from a total of seven patients (three patients at dose level one, three patients at dose level two and one patient at dose level three) demonstrating no evidence of Graft-versus-Host disease (GvHD) along with initial evidence of clinical response in the form of two partial responses. Importantly, CYAD-211 cells were detected within the peripheral blood of all patients analyzed with an apparent stepwise engraftment across the three dose levels.
• Enrollment in the trial is ongoing with plans to explore higher doses of preconditioning regimens in future cohorts. A clinical update will be presented at the upcoming ASH meeting in December 2021.

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

• CYAD-203 is the Company’s first armored CAR T candidate engineered to co-express the cytokine IL-18 with the NKG2D CAR receptor. To the Company’s knowledge, CYAD-203 is the first allogeneic IL-18 secreting CAR T candidate.
• Investigational New Drug (IND)-enabling studies are currently in progress alongside production of the clinical grade vector.
• Submission of the IND application for CYAD-203 is expected in mid-2022.
• At the SITC 36^th Annual Meeting, preclinical data will be presented demonstrating the enhanced anti-tumor activity of NKG2D CAR T cells armored with IL-18.

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

• CYAD-02, the Company’s autologous CAR T candidate with shRNA technology that targets the NKG2D ligands MICA and MICB, is currently being evaluated for the treatment of r/r AML / MDS in the Phase 1 CYCLE-1 dose-escalation trial.
• Additional safety and efficacy data from the trial will be presented at the upcoming ASH meeting in December 2021.

Upcoming Anticipated Milestones

• Initiation of the Phase 1b KEYNOTE-B79 trial evaluating CYAD-101 with KEYTRUDA^® in mCRC patients with MSS/pMMR disease is anticipated by year-end 2021.
• Additional data from the Phase 1 IMMUNICY-1 trial of CYAD-211 and the Phase 1 CYCLE-1 trial of CYAD-02 are expected at the upcoming ASH meeting in December 2021.
• Submission of the IND application for CYAD-203 for treatment of solid tumors is expected in mid-2022.
