Preclinical data with SC262, a HIP-modified CD22-directed allogeneic CAR T cell, further support completed IND submission Validation of novel and fully-human GPRC5D-specific CARs for the development of a HIP-modified allogeneic GPRC5D-directed CAR T cell therapy SEATTLE, Dec. 11, 2023 (GLOBE NEWSWIRE) -- Sana Biotechnology, Inc. (NASDAQ: SANA), a company focused on changing the possible for patients through engineered cells, today announced preclinical data supporting the anti-tumor and immune evasion capabilities of allogeneic CAR T cells engineered with Sana’s proprietary hypoimmune (HIP) technology were presented at the 65th American Society of Hematology (ASH) Annual Meeting in San Diego, CA. “These data, indicating that HIP-modified CAR T cells are consistently able to avoid detection by the immune system while retaining their functionality and eliciting an anti-tumor effect, add to our learnings about and the opportunities for our allogeneic CAR T cell platform,” said Terry Fry, MD, Sana’s Senior Vice President and Head of T Cell Therapeutics. “HIP-modified allogeneic CAR T cells remain well-tolerated in preclinical models. We look forward to initiating several additional clinical studies with our promising therapeutic candidates, with proof-of-concept data from multiple trials expected next year, including from SC291, our CD19-targeted HIP-modified CAR T cell therapy, and SC262. We also continue to develop our allogeneic CAR T cell pipeline, including our fully-human GPRC5D-targeted CAR T cell therapy.” On Sunday, December 10, abstract #3437 titled “Hypoimmune, Allogeneic CD22-Directed CAR T Cells That Evade Innate and Adaptive Immune Rejection for the Treatment of Large B Cell Lymphoma Patients That Are Relapsed/Refractory to CD19-Directed CAR T Cell Therapy” detailed preclinical data supporting the advancement of SC262, a CD22-directed HIP CAR T cell therapy, into human clinical studies. The results demonstrated that CD22 HIP CAR T cells evaded adaptive immune cell recognition and cytolysis through B2M and CIITA gene disruption and innate immune cell recognition through the overexpression of CD47. Furthermore, CD22 HIP CAR T cells elicited robust tumor control that produced cytokine/effector analytes and expanded in a dose- and antigen-dependent manner in vitro, with consistent effect across lots manufactured from different donors. CD22 HIP CAR T cells were well tolerated with no signs of graft-versus-host disease (GvHD). Sana submitted the investigational new drug (IND) application and intends to begin human testing of SC262 in early 2024. On Sunday, December 10, abstract #3290 titled “Development of a Novel, Allogeneic GPRC5D-Directed CAR for Treatment of Multiple Myeloma Patients” outlined preclinical data demonstrating the characterization and candidate selection of fully-human GPRC5D-specific CARs for use in combination with HIP technology to develop an allogeneic GPRC5D CAR T cell therapy. The data showed that candidate GPRC5D CARs elicited in vitro cytotoxicity and effector cytokine production that is comparable to clinically validated benchmark control CARs. Additionally, these GPRC5D CAR T cells controlled multiple myeloma tumor cells both in vitro and in vivo, demonstrating efficacy that is on par with clinical benchmark GPRC5D CAR T cells.

– Data presented at 65th ASH Annual Meeting show CNTY-101 was generally well tolerated at Dose Level 1 (100 million cells) in a high-risk, heavily pretreated R/R B-cell lymphoma patient – – Preliminary clinical data demonstrate six-month durable complete response in Dose Level 1 in a single patient following multiple cycles of CNTY-101 without lymphodepletion – – Pharmacokinetic data suggests CNTY-101 exposure may be maintained upon administration of additional cycles without lymphodepletion due to lack of observed allo-rejection – – Company to host conference call on Monday, December 11 at 7:30 AM PT/10:30 AM ET to review ASH data including additional clinical results from Dose Level 1 (100 million cells) and Dose Level 2 (300 million cells), as well as clinical plans for CNTY-101 in systemic lupus erythematosus – PHILADELPHIA, Dec. 09, 2023 (GLOBE NEWSWIRE) -- Century Therapeutics (NASDAQ: IPSC), an innovative biotechnology company developing induced pluripotent stem cell (iPSC)-derived cell therapies in immuno-oncology and autoimmune and inflammatory disease, today announced the presentation of initial clinical data from a single-patient case study which Century believes support the potential for a multi-dosing strategy for CAR iNK enabled by Allo-Evasion™ edits at the 65th American Society of Hematology (ASH) Annual Meeting and Exposition, being held December 9-12 in San Diego. The poster, titled, “Multiple Doses of CNTY-101, an iPSC-Derived Allogeneic CD19 Targeting CAR-NK Product, are Safe and Result in Tumor Microenvironment Changes Associated with Response: A Case Study”, is available on the Scientific Resources page of the Company’s website. “We are thrilled that the initial clinical evidence for CNTY-101 provides support for the potential for Allo-Evasion™ to enable a multi-dosing regimen without the need for continued lymphodepletion. This is highly encouraging in advancing our goal to increase persistence of the cells during the treatment period and potentially lead to deeper and more durable responses,” said Brent Pfeiffenberger, Pharm.D., Chief Executive Officer of Century Therapeutics. “We look forward to advancing the study at both higher and more frequent doses of CNTY-101, and plan to present additional clinical data in mid-2024.” “As the first cell therapy product candidate engineered with six precision gene edits aimed at providing selectivity and persistence, CNTY-101 is positioned to potentially fill a high unmet need among heavily pretreated non-Hodgkin lymphoma patients,” said Krish Patel, M.D., Director of Lymphoma Program, Director of Hematologic Malignancies and Cellular Therapy, Swedish Cancer Institute, Seattle. “The encouraging initial data presented today from this patient who received low doses of CNTY-101 exhibits signals of persistence of CNTY-101 cells out of circulation and supports testing at higher doses. I look forward to the continuation of the study and to further investigating the full therapeutic potential of CNTY-101.” Data featured in a single-patient case study presented at ASH involves a 63-year-old patient with relapsed/refractory (R/R) progressive follicular lymphoma previously treated with four prior lines of therapy who was enrolled at Dose Level 1 (100 million cells). As of a data cutoff date of November 13, 2023, the patient has received seven 28-day cycles of a single infusion of CNTY-101 at Dose Level 1. Cycles one and two included three days of lymphodepletion (LD), whereas cycles three through seven were given with no LD. Interleukin-2 (IL-2) was administered for all cycles except for the first. The patient maintained a complete response with a duration of six months before subsequently progressing. Data from the single-patient case study indicated that CNTY-101 was generally well tolerated in this patient at Dose level 1 (100 million cells). No dose-limiting toxicities, cytokine release syndrome or immune effector cell–associated neurotoxicity syndrome were observed, and no adverse events related to treatment with CNTY-101 were detected in this patient, to date. Additionally, no concerted changes in inflammatory cytokines and mediators associated with cytokine release syndrome or neurotoxicity have been detected in this patient. Following administration of two cycles with and three cycles without LD, serum assessments from available data of the first five cycles of CNTY-101 treatment in this patient showed no evidence of functional pre-existing or induced humoral immunogenicity against CNTY-101. Importantly, tumor microenvironment initial analyses demonstrated a vigorous increase in T cells within 8 days of the 1st CNTY-101 cell infusion. Increases in proliferating cytotoxic T cells and TNFα and IFNγ-secreting cells were observed, suggestive of induction of adaptive immune responses within the tumor. Additionally, ddPCR analysis of CNTY-101 genomic DNA and cell-free DNA from Dose Level 1 patient (n=4) samples suggest that CNTY-101 cells were able to traffic out of circulation shortly after infusion and showed persistence in tissues for at least 3 days. In addition to the preliminary clinical data presented today, the Company will also present additional results from patients treated at Dose Level 1 (100 million cell dose), as well as preliminary data from three patients treated at Dose Level 2 (300 million cell dose) during a conference call and webcast on Monday, December 11 at 7:30 AM PT/10:30 AM ET. In addition, the Company will discuss its planned Phase 1 trial, including supporting preclinical data, for CNTY-101 in systemic lupus erythematosus, the Company’s first autoimmune and inflammatory disease indication. Conference Call and Webcast The live audio webcast and accompanying slides may be accessed through the Events & Presentations page in the Investors section of the Company's website. Alternatively, the conference call may be accessed through the following: Conference ID: century2023Domestic Dial-in Number: (800) 590-8290International Dial-in Number: (240) 690-8800 Live webcast: https://century-therapeutics-initial-clinical-data-call.open-exchange.net/ For those unable to participate in the conference call or webcast, a replay will be available on the Investors section of the Company's website at www.centurytx.com approximately 24 hours after the conference call and will be available for 90 days following the call. About Allo-Evasion™ Century’s proprietary Allo-Evasion™ technology is used to engineer cell therapy product candidates with the potential to evade identification by the host immune system so they can be dosed multiple times without rejection, enabling increased persistence of the cells during the treatment period and potentially leading to deeper and more durable responses. More specifically, Allo-Evasion™ 1.0 technology incorporates three gene edits designed to avoid recognition by patient/host CD8+ T cells, CD4+ T cells and NK cells. Knockout of beta-2-microglobulin or β2m, designed to prevent CD8+ T cell recognition, knock-out of the Class II Major Histocompatibility Complex Transactivator, or CIITA, designed to prevent CD4+ T cell recognition, and knock-in of the HLA-E gene, designed to enable higher expression of the HLA-E protein to prevent killing of CNTY-101 cells by host NK cells. Allo-Evasion™ technology may allow the implementation of more flexible and effective repeat dosing protocols for off-the-shelf product candidates. About ELiPSE-1 The Phase 1 ELiPSE-1 trial (NCT05336409) is intended to assess the safety, tolerability, pharmacokinetics, and preliminary efficacy of CNTY-101 in adult patients with relapsed or refractory CD19-positive B-cell lymphomas. All patients will receive an initial standard dose of conditioning chemotherapy consisting of cyclophosphamide (300 mg/m2) and fludarabine (30mg/m2) for 3 days. Schedule A of the trial includes a single-dose escalation of CNTY-101 and subcutaneous IL-2. Schedule B will evaluate a three-dose schedule per cycle of CNTY-101. Patients who demonstrate a clinical benefit are eligible for additional cycles of treatment with or without additional lymphodepletion. About CNTY-101 CNTY-101 is an investigational off-the-shelf immunotherapy product candidate that utilizes iPSC-derived natural killer (NK) cells with a CD19-directed chimeric antigen receptor (CAR) and includes Century’s core Allo-Evasion™ edits designed to overcome the three major pathways of host versus graft rejection - CD8+ T cells, CD4+ T cells and NK cells. In addition, the product candidate is engineered to express IL-15 to provide homeostatic cytokine support, which has been shown pre-clinically to improve functionality and persistence. Further, to potentially improve safety, the iNK cells were engineered with an EGFR safety switch, and proof-of-concept studies have demonstrated that the cells can be quickly eliminated by the administration of cetuximab, an antibody against EGFR approved by the U.S. Food and Drug Administration for certain cancers. Century is currently assessing CNTY-101 in patients with relapsed or refractory CD19-positive B-cell lymphomas in its Phase 1 ELiPSE-1 clinical trial and intends to initiate its second Phase 1 clinical trial assessing CNTY-101 in patients with moderate to severe systemic lupus erythematosus.

– Represents second IND clearance for CNTY-101, the Company’s lead iPSC-derived CD19-targeted CAR NK cell product candidate, and first in an autoimmune and inflammatory disease indication – – Company plans to initiate the Phase 1 clinical trial in the first half of 2024; initial data expected by year-end 2024 – –CNTY-101 is the first cell therapy product candidate engineered with six precision gene edits including a CD19-CAR, Allo-Evasion™ technology, IL-15 cytokine support and a safety switch – PHILADELPHIA, Dec. 06, 2023 (GLOBE NEWSWIRE) -- Century Therapeutics, Inc. (NASDAQ: IPSC), an innovative biotechnology company developing induced pluripotent stem cell (iPSC)-derived cell therapies in immuno-oncology and autoimmune and inflammatory disease, today announced that the Company has been notified by the U.S. Food and Drug Administration (FDA) that the Company’s Phase 1 clinical trial may proceed to assess CNTY-101 in patients with moderate to severe systemic lupus erythematosus (SLE) who have failed at least two standard immunosuppressive therapies. This represents the first Investigational New Drug (IND) application clearance for an autoimmune and inflammatory disease indication for CNTY-101, and is built on the emerging data and experience gained from administering multiple cycles of CNTY-101, with and without lymphodepletion, under the open IND for CNTY-101 in relapsed/refractory B-cell malignancies. Despite recent advances, therapies for SLE have failed to make a significant impact on morbidity, and induction of remission remains rare, while treatment toxicity and disease flares are common. B-cell-directed autologous CAR T cell therapies have provided new hope for durable remissions through an “immune reset”. However, some of the challenges encountered with auto-CAR-T in oncology related to product availability, toxicities, and potential long-term risks could hamper their wide-spread adoption in non-oncology indications. Century is pursuing an alternative approach with CNTY-101, an allogeneic, off-the-shelf iPSC-derived NK cell product candidate. CNTY-101 contains 6 genetic edits at defined loci, engineered via homology directed repair using CRISPR. These include three Allo-Evasion™ edits, secreted IL-15, a CD19 CAR, and a safety switch allowing for cell removal if required. As a homogenous NK cell candidate derived from a single iPSC clone, CNTY-101 has been designed with uniquely engineered features which Century believes may provide multiple potential treatment advantages. These potential advantages include availability of a consistent off-the-shelf frozen product, an improved tolerability profile, ability to be re-dosed without lymphodepletion while avoiding allo-rejection of the product, and a product design that may enable the elimination of B cells to effect a decline in auto-antibodies without prolonged B cell aplasia. “Today marks an important milestone in Century’s evolution as a company. We believe the unique pro CNTY-101, which incorporates multiple precision edits including our Allo-Evasion™ technology, positions it as an off-the-shelf allogeneic treatment option that could meaningfully improve outcomes for patients with SLE for whom existing therapies fall short,” said Brent Pfeiffenberger, Pharm.D., Chief Executive Officer of Century Therapeutics. “The expansion of the CNTY-101 program into SLE represents a significant achievement for the Company, and, importantly, serves as a testament to the unwavering dedication of our team as we continue to execute on our mission to advance differentiated and potentially curative cell therapies to patients with cancer and autoimmune and inflammatory diseases.” The multi-center Phase 1 clinical trial is designed to assess the safety, tolerability, pharmacokinetics, and clinical response of CNTY-101 in patients with moderate to severe SLE who have failed at least two standard immunosuppressive therapies. The trial will evaluate one to two cycles of 3 weekly doses of CNTY-101, with lymphodepletion only included prior to the first CNTY-101 infusion. The Company plans to initiate the trial in the first half of 2024, with initial data expected by the end of 2024. About Allo-Evasion™ Century’s proprietary Allo-Evasion™ technology is used to engineer cell therapy product candidates with the potential to evade identification by the host immune system so they can be dosed multiple times without rejection, enabling increased persistence of the cells during the treatment period and potentially leading to deeper and more durable responses.
