"The recent announcement of the dosing of our first patient with CYAD-211 in the IMMUNICY-1 trial was a major milestone for the organization as we continue to strategically focus on next-generation allogeneic CAR T cell therapies underpinned by our innovative shRNA technology platform that we took from concept to clinic in just two years," said Filippo Petti, Chief Executive Officer of Celyad Oncology. "With IMMUNICY-1, we’re not only looking to offer patients with refractory multiple myeloma an option where few exist, but also to use this as an opportunity to validate the use of our shRNA platform as a novel allogeneic technology in what we believe could greatly expand our potential to develop best-in-class, off-the-shelf CAR T cell therapies."

Mr. Petti added, "While we are disappointed by the latest update from the Phase 1 THINK trial for CYAD-01, we are encouraged by the initial clinical results from our next-generation CYAD-02 candidate for the treatment of patients with relapsed or refractory AML and MDS and look forward to future updates from the CYCLE-1 trial. With greater perspective on our autologous programs, the organization will remain steadfast in our commitment to patients with cancer by continuing to concentrate on the discovery and development of novel, allogeneic CAR T candidates."

CYAD-211 and IMMUNICY-1 Phase 1 Trial Update

Background

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 complex.
IMMUNICY-1 will evaluate the safety and clinical activity of a single infusion of CYAD-211 following preconditioning chemotherapy cyclophosphamide and fludarabine in patients with relapsed/refractory multiple myeloma (r/r MM).
The trial seeks to determine the recommended dose of CYAD-211 in r/r MM patients for further development as well as to establish proof-of-principle that single shRNA-mediated knockdown can generate allogeneic CAR T cells in humans without inducing Graft-versus-Host Disease (GvHD).
On December 4, 2020, the company announced dosing of the first patient in the CYAD-211 Phase 1 IMMUNICY-1 trial.
Preclinical Results

CYAD-211 demonstrated robust anti-tumor activity in vitro and in vivo concurrent with lack of alloreactivity in preclinical MM models.
No demonstrable evidence of GvHD was observed with CYAD-211 in preclinical models confirming efficient inhibition of alloreactivity.
Study Design

The IMMUNICY-1 trial is a first-in-human, open-label dose-finding study evaluating three dose levels of CYAD-211, including 3×107, 1×108 and 3×108 cells per infusion, in patients with r/r MM.
Next Steps

Proof-of-principle data from the initial dose cohorts are expected during first half 2021.
Clinical activity data from the full dose-escalation trial are expected during second half 2021.
CYAD-01 and THINK Phase 1 Trial Update

Background

The company’s first generation NKG2D receptor-based CAR T clinical candidate CYAD-01 was evaluated for the treatment of patients with r/r acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS) in the Phase 1 THINK trial.
In 2019, the company implemented the OptimAb manufacturing process within the CYAD-01 program, to be evaluated in the study expansion cohort of the THINK trial. The trial intended to assess the safety and clinical activity of CYAD-01 when produced with the OptimAb process following no preconditioning chemotherapy.
Latest Clinical Data

Overall, eight of the eleven patients planned per protocol in the THINK trial were treated with OptimAb-produced CYAD-01 cells.
No dose-limiting toxicities were reported from patients treated with OptimAb-produced CYAD-01 cells.
Stable disease (SD) was achieved in two of eight patients treated with OptimAb-produced CYAD-01 cells (one MDS and one AML patient); an additional MDS patient became eligible for an allogeneic stem cell transplantation after treatment with CYAD-01 and achieved a complete response. No objective responses were observed following treatment with OptimAb-produced CYAD-01 cells.
Next Steps

Based on clinical futility observed to date of CYAD-01 from the Phase 1 THINK trial the company has decided to discontinue the development of CYAD-01 for the treatment of r/r AML / MDS. No additional patients will be enrolled in the CYAD-01 program.
CYAD-02 and CYCLE-1 Phase 1 Trial Update

Background

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 r/r AML / MDS.
The next-generation, NKG2D receptor-based CAR T candidate CYAD-02 incorporates shRNA to target the NKG2D ligands MICA and MICB. In preclinical models, shRNA-mediated knockdown of MICA and MICB expression on NKG2D receptor-based CAR T cells has shown enhanced in vitro expansion, as well as enhanced in vivo engraftment and persistence of the CAR T cells, as compared to first-generation NKG2D receptor-based CAR T cells.
Preliminary Clinical Data

To date, nine patients have received treatment with CYAD-02: three patients at dose level 1, three patients at dose level 2 and three patients at dose level 3.
CYAD-02 was generally well-tolerated, with one grade 4 infusion reaction (dose level 1) and one grade 3 cytokine release syndrome (dose level 3). Both patients recovered rapidly following the appropriate treatment.
To date, seven patients were evaluable for clinical activity:
Of the five very high-risk MDS patients: (i) three patients demonstrated anti-leukemic activity (at least 50% bone marrow blasts decrease) with the single patient evaluated at dose level 3 achieved a marrow complete response (mCR) at first assessment (ongoing); (ii) two additional patients exhibited a durable SD of more than five months (one of two ongoing).
Of the two adverse AML patients, one patient demonstrated anti-leukemic activity with a SD of four months (ongoing).
Next Steps

The dose level 3 cohort of the CYCLE-1 trial is ongoing. Additional safety and efficacy data from the trial are expected during the first half of 2021.

About CYAD-211

CYAD-211 is an investigational, short hairpin RNA (shRNA)-based allogeneic CAR T candidate for the treatment of relapsed or refractory multiple myeloma (r/r MM). CYAD-211 is 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 July 2020, Celyad Oncology announced FDA Clearance of its IND application for CYAD-211.

About CYAD-01

CYAD-01 is an investigational CAR T therapy in which a patient’s T cells are engineered to express a chimeric antigen receptor (CAR) based on NKG2D, a receptor expressed on natural killer (NK) cells that binds to eight stress-induced ligands expressed on tumor cells.

About CYAD-02

CYAD-02 is an investigational CAR T therapy that engineers an all-in-one vector approach in patient’s T cells to express both (i) the NKG2D chimeric antigen receptor (CAR), a receptor expressed on natural killer cells that binds to eight stress-induced ligands expressed on tumor cells, and (ii) short hairpin RNA (shRNA) SMARTvector technology licensed from Horizon Discovery to knockdown the expression of NKG2D ligands MICA and MICB on the CAR T cells. In preclinical models, shRNA-mediated knockdown of MICA and MICB expression on NKG2D CAR T cells has shown enhanced in vitro expansion, as well as enhanced in vivo engraftment and persistence, of the CAR T cells, as compared to first-generation NKG2D receptor based CAR T cells.

"Our imetelstat presentations at this year’s ASH (Free ASH Whitepaper) provide strong support for our two registration-enabling Phase 3 clinical trials: IMerge, in lower risk MDS and IMpactMF, in refractory MF," said Aleksandra Rizo, M.D., Ph.D., Geron’s Chief Medical Officer. "We believe the analyses and data from our Phase 2 IMerge and IMbark trials provide strong evidence of imetelstat’s disease-modifying activity, as well as clinical benefits of durable transfusion independence in MDS and improvement in overall survival in MF."

Lower Risk Myelodysplastic Syndromes (MDS) – Oral Presentation

Title: Treatment with Imetelstat Provides Durable Transfusion Independence (TI) in Heavily Transfused Non-del(5q) Lower Risk MDS (LR-MDS) Relapsed/Refractory (R/R) to Erythropoiesis Stimulating Agents (ESAs) (Abstract #658)

The oral presentation reported long-term efficacy, safety and biomarker data from 38 patients in the IMerge Phase 2 clinical trial, based on a February 4, 2020 cut-off date and a median follow-up of 24 months. Consistent with prior presentations, 42% of patients achieved >8-week red blood cell transfusion independence (RBC-TI) with a median duration of 20 months, which is the longest so far reported with any agent in relapsed/refractory non-del(5q) lower risk MDS. In addition, 29% of patients were transfusion free more than a year. Reduction in the SF3B1 mutation, one of the key mutations correlated with ineffective erythropoiesis in lower risk MDS, correlated with longer transfusion independence and shorter onset to achieve transfusion independence. These biomarker data together with the durability of transfusion independence provide evidence for the disease-modifying activity of imetelstat. These data were previously presented at the European Hematology Association (EHA) (Free EHA Whitepaper) Annual Congress in June.

Relapsed/Refractory Myelofibrosis (MF) – Three Oral Presentations

Title: Potential Disease-Modifying Activity of Imetelstat Demonstrated By Reduction in Cytogenetically Abnormal Clones and Mutation Burden Leads to Clinical Benefits in Relapsed/Refractory Myelofibrosis Patients (Abstract #346)

This oral presentation reported significant dose-dependent reduction of mutation burden by imetelstat, including complete elimination of mutations in MF driver and non-driver genes. A greater than 20% reduction in variant allele frequency by imetelstat treatment correlated with improved clinical benefits, including higher rates of spleen and symptom responses, bone marrow fibrosis improvement and longer overall survival (OS). As concluded in the presentation, imetelstat demonstrated disease-modifying activity by targeting malignant clones, improvement in bone marrow fibrosis and OS.

Title: Telomerase Activity, Telomere Length and hTERT Expression Correlate with Clinical Outcomes in Higher-Risk Myelofibrosis (MF) Relapsed/Refractory (R/R) to Janus Kinase Inhibitor Treated with Imetelstat (Abstract #347)

This oral presentation reported dose-dependent inhibition of telomerase, as evaluated by reductions in telomerase activity, human reverse transcriptase (hTERT) levels and telomere length in patients treated with imetelstat in the IMbark Phase 2 clinical trial. Analyses of these biomarker data correlated with clinical responses and longer OS. In addition, dose-dependent reduction in variant allele frequency of driver mutations was noted, indicating that imetelstat has disease-modifying activity by targeting the underlying MF malignant clones. As expected for a telomerase inhibitor, treatment with imetelstat at 9.4 mg/kg improved clinical outcomes in patients with shorter telomeres and higher hTERT expression at baseline. These data are consistent with telomere biology in cancer cells and provide evidence for on-target mechanism of action of imetelstat through telomerase inhibition. These results were previously reported as a poster presentation at the EHA (Free EHA Whitepaper) Annual Congress in June.

Title: Favorable Overall Survival with Imetelstat Treatment Correlates with Other Clinical Benefits in Intermediate-2 or High-Risk Myelofibrosis Relapsed/Refractory to Janus Kinase Inhibitor (Abstract #53)

This oral presentation reported the correlation of overall survival results from the IMbark Phase 2 with clinical benefits observed with imetelstat treatment. The correlation analyses showed a trend of longer OS in patients who achieved symptom response, spleen volume reductions ranging from > 10% to > 35%, and statistically significant improvement in OS in patients with improved bone marrow fibrosis, in a dose-dependent manner. These results were previously reported as a poster presentation at the EHA (Free EHA Whitepaper) Annual Congress in June.

Relapsed/Refractory Myelofibrosis (MF) – Three Poster Presentations

Collectively, these poster presentations described on-target and disease-modifying activity of the higher dose of imetelstat from the IMbark Phase 2, and how that relates to better clinical outcomes, including OS, fibrosis improvement and symptom response, especially in a subset of patients defined as triple negative MF, known to have poor outcome.

Title: Correlation Analyses of Imetelstat Exposure with Pharmacodynamic Effect, Efficacy and Safety in A Phase 2 Study in Patients with Higher-risk Myelofibrosis Refractory to Janus Kinase Inhibitor Identified an Optimal Dosing Regimen for Phase 3 Study (Abstract #1283)

Title:Imetelstat Treatment Results in Clinical Benefits, Including Improved Overall Survival, in Patients with Higher-Risk Triple Negative Myelofibrosis Relapsed/Refractory to Janus Kinase Inhibitors (JAKi) (Abstract #3084)

Title:Treatment with Imetelstat Improves Myelofibrosis-Related Symptoms and Other Patient-Reported Outcomes in Patients with Relapsed or Refractory Higher-Risk Myelofibrosis (Abstract #3088)

Myeloproliferative Neoplasms (MPN) – Poster Presentation

Title: Imetelstat Inhibits Telomerase and Prevents Propagation of ADAR1-Activated Myeloproliferative Neoplasm and Leukemia Stem Cells (Abstract #1264)

Collaborators at UC San Diego reported non-clinical data on hTERT and ADAR1 activity in pre-leukemia stem cells and leukemia stem cells (LSC). In various lab experiments and animal models, treatment with imetelstat prevented pre-leukemia stem cells from evolving into LSCs, suggesting telomerase inhibition may be an effective strategy for preventing MPN progression.

Two Trials in Progress Poster Presentations – Ongoing IMerge Phase 3 and Upcoming IMpactMF Phase 3

Title:IMerge: A Phase 3 Study to Evaluate Imetelstat in Transfusion-Dependent Subjects with IPSS Low or Intermediate-1 Risk Myelodysplastic Syndromes (MDS) that is Relapsed/Refractory to Erythropoiesis-Stimulating Agent (ESA) Treatment (Abstract #3113)

The IMerge Phase 3 clinical trial is a double-blind, randomized, placebo-controlled clinical trial with registration intent. The trial is designed to enroll approximately 170 transfusion dependent patients with Low or Intermediate-1 risk myelodysplastic syndromes (MDS), also referred to as lower risk MDS, who have relapsed after or are refractory to prior treatment with an erythropoiesis stimulating agent (ESA). The IMerge Phase 3 is currently enrolling patients.

The primary endpoint is the rate of red blood cell (RBC) transfusion independence (TI) for any consecutive period of eight weeks or longer, or 8-week RBC-TI rate. Key secondary endpoints include the rate of RBC-TI lasting at least 24 weeks, or 24-week RBC-TI rate, and the rate of hematologic improvement-erythroid (HI-E), defined as a reduction of at least four units of RBC transfusions over eight weeks compared with the prior RBC transfusion burden.

Title:A Randomized Open-Label, Phase 3 Study to Evaluate Imetelstat Versus Best Available Therapy in Patients with Intermediate-2 or High-risk Myelofibrosis (MF) Refractory to Janus Kinase (JAK) Inhibitor (Abstract #2194)

The IMpactMF Phase 3 clinical trial in refractory MF is a registration-enabling trial with OS as the primary endpoint. Approximately 320 patients with Intermediate-2 or High-risk MF will be randomized to receive either imetelstat or best available therapy, which will exclude JAK inhibitors. Key secondary endpoints include symptom response, spleen response, progression free survival, complete response, partial response, clinical improvement, duration of response, safety, pharmacokinetics, and patient reported outcomes.

Geron expects the trial to be open for screening and enrollment in the first quarter of 2021.

About Phase 2 IMerge and IMbark Trials

The IMerge Phase 2 was an open label, single arm trial to assess the safety and efficacy of a 7.5 mg/kg dose of imetelstat administered as an intravenous infusion every four weeks in transfusion dependent lower risk MDS patients who had relapsed after or were refractory to prior treatment with ESA. The IMerge Phase 2 is no longer enrolling patients, and patients remaining in the treatment phase continue to receive imetelstat treatment, per investigator discretion.

The IMbark Phase 2 was designed to evaluate two dosing regimens of imetelstat (either 4.7 mg/kg or 9.4 mg/kg administered by intravenous infusion every three weeks) in patients with Intermediate-2 or High-risk myelofibrosis (MF) who have relapsed after or are refractory to prior treatment with a janus kinase inhibitor (JAKi). The co-primary efficacy endpoints for IMbark were spleen response rate, defined as the proportion of patients who achieve a reduction of at least 35% in spleen volume as assessed by imaging, and symptom response rate, defined as the proportion of patients who achieve a reduction of at least 50% in Total Symptom Score (TSS), at 24 weeks. Key secondary endpoints were overall survival (OS) and safety. The trial is complete and closed.

About Imetelstat

Imetelstat is a novel, first-in-class telomerase inhibitor exclusively owned by Geron and being developed in hematologic myeloid malignancies. Early clinical data strongly suggest that imetelstat has disease-modifying activity through the apoptosis of malignant stem and progenitor cells, which allows potential recovery of normal hematopoiesis. Current clinical studies of imetelstat include IMerge, an ongoing Phase 2/3 trial in lower risk myelodysplastic syndromes (MDS), and IMpactMF, an upcoming Phase 3 clinical trial in refractory myelofibrosis (MF). Imetelstat has been granted Fast Track designation by the United States Food and Drug Administration for both the treatment of patients with non-del(5q) lower risk MDS who are refractory or resistant to an erythropoiesis-stimulating agent and for patients with Intermediate-2 or High-risk MF whose disease has relapsed after or is refractory to janus kinase (JAK) inhibitor treatment.

"Our presentations at ASH (Free ASH Whitepaper), as of a data cutoff of November 3, build upon our last corporate update from September 8," said Jan Skvarka, President and CEO of Trillium Therapeutics. "We presented data where TTI-622 continued to demonstrate a strong safety profile, as well as further dose-dependent improvements in receptor occupancy and PK data. We completed a safety evaluation of the 12 mg/kg dose level, with results indicating no observed dose-limiting toxicity or other major safety concerns, and we escalated dosing to 18 mg/kg. As of the November 3 cutoff, one patient at the 12 mg/kg dose level achieved a stable disease assessment and continued on therapy. TTI-621 continued dosing at 2 mg/kg. We are looking forward to further progress in 2021, moving to combination studies in heme malignancies and solid tumors, and building on a foundation of demonstrated monotherapy activity of our molecules."

The posters and oral presentation described below were presented at ASH (Free ASH Whitepaper):

TTI-622: Poster Presentation, Publication Number 1191

Investigational CD47-Blocker TTI-622 Shows Single-Agent Activity in Patients with Advanced Relapsed or Refractory Lymphoma: Update from the Ongoing First-in-Human Dose Escalation Study

Presenter: Krish Patel, M.D., Center for Blood Disorders and Stem Cell Transplantation, Swedish Cancer Institute, Seattle, WA

Session: 626. Aggressive Lymphoma (Diffuse Large B-Cell and Other Aggressive B-Cell Non-Hodgkin Lymphomas)-Results from Prospective Clinical Trials: Poster I

This poster presentation provided a further update on the safety and anti-tumor activity observed in the ongoing open-label Phase 1 dose escalation study of TTI-622 in patients with relapsed or refractory lymphoma (NCT03530683). As of the data cutoff date of November 3, a total of 31 patients had been enrolled in the first seven cohorts, receiving weekly intravenous doses between 0.05-12 mg/kg. All dose levels were well tolerated and a maximum tolerated dose (MTD) was not reached. Adverse events (AEs) were predominantly Grade 1-2; related AEs ≥Grade 3 were neutropenia (13%), thrombocytopenia (3%) and anemia (3%). Dose-dependent increases in TTI-622 serum exposure supported continued dose escalation beyond 12 mg/kg, and dose-dependent increases in receptor occupancy (RO) durability were observed. Objective responses were achieved in 6 of 22 (27%) response-evaluable patients, with an overall response rate (ORR) of 35% (6/17) among response-evaluable patients at dose levels ≥0.8 mg/kg. All responses occurred within the first eight weeks of treatment across multiple lymphoma indications, and included one complete response (CR) and five partial responses. The CR patient treatment was ongoing at 534 days and showed evidence of expansion of new and existing T-cell clones. The study is currently dosing at 18 mg/kg.

TTI-621: Oral Presentation, Publication Number 646

Updates from Ongoing, First-in-Human Phase 1 Dose Escalation and Expansion Study of TTI-621, a Novel Biologic Targeting CD47, in Patients with Relapsed or Refractory Hematologic Malignancies

Presenter: Steven M. Horwitz, M.D., Department of Medicine, Lymphoma Service, Memorial Sloan Kettering Cancer Center, New York, NY

Session: 624. Hodgkin Lymphoma and T/NK Cell Lymphoma-Clinical Studies: Immunotherapy in T/NK Cell Lymphoma

This oral presentation provided a further update on the safety and anti-tumor activity observed in the ongoing open-label Phase 1 dose escalation study of intravenous TTI-621 in patients with relapsed or refractory hematologic malignancies (NCT02663518). The study consists of four parts: (a) "Parts 1-3" in hematologic malignancies, with dosing up to 0.5 mg/kg, conducted under initial dose-limiting toxicity (DLT) criteria, now complete; and (b) "Part 4" in cutaneous T-cell lymphoma (CTCL), utilizing revised DLT criteria for thrombocytopenia and an amended protocol to allow for dosing above 0.5 mg/kg, currently ongoing. In Part 4, 17 CTCL patients, including two at the 2 mg/kg dose level, completed DLT evaluation as of the November 3, 2020 data cutoff. TTI-621 was well tolerated and an MTD in Part 4 was not reached. Across Parts 1-4, the most common treatment-related AEs were infusion-related reactions (44%) and thrombocytopenia (30%), which was transient and not dose-limiting. Monotherapy activity was observed in CTCL (17% ORR), peripheral T-cell lymphoma (18% ORR) and diffuse large B-cell lymphoma (29% ORR). The majority of these patients received doses of 0.5 mg/kg or lower; a dose-efficacy relationship in Part 4 was difficult to ascertain due to the small sample sizes. Dose-dependent increases in drug exposure and RO of 40-65% at doses 0.5-1.4 mg/kg were observed. Evidence of changes in both innate and adaptive immune cells was apparent in a responding CTCL patient. The study is currently enrolling at the 2 mg/kg dose level.

The posters are available in the Events & Presentations section of the Company’s website, and an updated corporate presentation can also be found on the Company’s website at www.trilliumtherapeutics.com.
