Century Therapeutics Presents Interim Results from Phase 1 ELiPSE-1 Study at ASCO 2024 Annual Meeting

In ongoing dose escalation, CNTY-101 has demonstrated a manageable safety profile with no observed DLTs or GvHD and with majority of patients treated in outpatient setting

Encouraging preliminary efficacy in heavily pretreated R/R NHL at initial dose levels

Novel cell-free DNA method for detecting total body PK suggests CNTY-101 persists outside the bloodstream

Enrollment continues in dose escalation phase of ELiPSE-1 at dose levels 3B (three weekly infusions of 1 billion cells) and 4A (single infusion of 3 billion cells) per cycle

PHILADELPHIA, June 3, 2024 – 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 a poster presentation highlighting interim results from the ongoing Phase 1 ELiPSE-1 study evaluating CNTY-101 in relapsed or refractory (R/R) non-Hodgkin lymphoma (NHL) at the American Society of Clinical Oncology (ASCO) Annual Meeting being held May 31 – June 4, 2024 in Chicago, Illinois.

CNTY-101 is an investigational CD19 targeting allogeneic, iPSC-derived natural killer (NK) cell therapy with six precision gene edits powered by Century’s Allo-Evasion™ technology enabling repeat dosing without the need for continued lymphodepletion. ELiPSE-1 (NCT05336409) is an ongoing Phase 1, multicenter, open-label clinical trial to evaluate the safety, tolerability, pharmacokinetics, and preliminary efficacy of CNTY-101 in patients with R/R, CD19-positive B-cell malignancies.

“These interim results continue to support our belief in the potential of CNTY-101, which shows additional responses across escalating doses and different types of B-cell malignancies in heavily pretreated patients with predominantly aggressive or high-risk histologies,” said Adrienne Farid, PhD, Chief Operations Officer and Head of Early Development. “We are also encouraged by the safety profile we are seeing at higher doses, with no dose-limiting toxicities to date, after multiple treatment cycles, which we believe was achieved by leveraging our proprietary Allo-Evasion™ technology to avoid host rejection. Further, the majority of these cycles have been administered in the outpatient setting, providing additional support for CNTY-101 as a new paradigm for allogeneic cell therapies. We look forward to completing dose escalation and moving into dose expansion in the coming months.”

Interim Results from the ELiPSE-1 Study: A Phase 1, Multicenter, Open-Label Study of CNTY-101 in Subjects with Relapsed or Refractory CD19-Positive B-Cell Malignancies

Poster Board Number: 6

Session Title: Hematologic Malignancies—Lymphoma and Chronic Lymphocytic Leukemia

Session Date & Time: Monday, June 3, 2024, from 9:00 am – 12:00 pm CDT

CNTY-101 is Century’s lead iNK cell therapy and the first iPSC-derived NK cell therapy engineered with six precision gene edits, featuring antigen-specific killing of CD19+ B cells, homeostatic cytokine support for enhanced persistence, Allo-Evasion™ edits to prevent rejection by the patients’ immune system, and a safety switch. CNTY-101 is being assessed in heavily pre-treated relapsed or refractory NHL patients with predominantly aggressive or high-risk indolent histologies who have received two to five prior therapies, four of whom received prior CAR-T therapy. The Company previously announced initial data in December 2023, demonstrating a favorable safety profile in the initial seven patients treated with Dose Level 1 (100 million cells) and Dose Level 2 (300 million cells) on a once monthly schedule. In these low dose levels, CNTY-101 demonstrated encouraging early response signals, including two complete responses (CRs) and one partial response (PR).

As of the interim data cutoff date of March 27, 2024, preliminary safety and efficacy were evaluated across Dose Level 1, Dose Level 2 and Dose Level 3 (one billion cells) and two dosing schedules (Schedule A with single infusion, and Schedule B with three weekly infusions, per cycle). CNTY-101 infusions of up to one billion cells per cycle (as a single infusion of one billion cells, or 3 weekly infusions of 300 million cells) demonstrated a favorable safety profile with no observations of graft-versus-host disease (GvHD) or dose-limiting toxicities (DLT), and 8/12 subjects received at least one cycle of CNTY-101 in an outpatient setting. Preliminary efficacy in all evaluable patients (n=10) across dose schedules and histologies demonstrated a complete response rate (CRR) of 30% and an objective response rate (ORR) of 40% in heavily pretreated patients, with a 40% CRR and 60% ORR observed in the five patients treated with the two higher Schedule A dose levels, 300 million cells and one billion cells.

Pharmacokinetics (PK) evaluated by a novel cell-free DNA (cfDNA) method for detecting total body PK showed that CNTY-101 rapidly traffics out of circulation and persists outside the bloodstream, with AUC trending to increase with dose level. In patients who received additional cycles of CNTY-101 without lymphodepleting chemotherapy, three out of four patients had positive detection of CNTY-101 on Day 3 and beyond. The ELiPSE-1 study is currently ongoing in the dose escalation phase and is enrolling in Dose Level 3B (one billion cells in three weekly infusions per cycle), and Dose Level 4A (single infusion of 3 billion cells per cycle).

The full poster will be available on the Scientific Resources page of Century’s website at the start of the poster presentation.

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 preclinically to improve functionality and persistence. Further, to address potential safety considerations, the iNK cells were engineered with an EGFR safety switch, and preclinical proof-of-concept studies have demonstrated that the cells can be quickly eliminated in vivo 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. The Company intends to initiate its second Phase 1 clinical trial assessing CNTY-101 in patients with moderate to severe systemic lupus erythematosus, in addition to pursuing additional regulatory filings in other prioritized autoimmune disease indications.

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.

23 ELiPSE - 1 initial data: Key takeaways Heavily pretreated and refractory patient population treated in first - in - human dose escalation trial Favorable safety profile; can be delivered in an outpatient setting Encouraging early efficacy signals at initial 3 dose levels in Schedule A Novel cfDNA assay enables monitoring of CNTY - 101 persistence in extravascular space; AUC increase trending with dose Initial data for CNTY - 101 supports the potential for Allo - Evasion ۲ to enable a multi - dosing regimen without the need for continued lymphodepletion CR: Complete Response CNTY - 101’s manageable initial safety profile, initial response data, and PK/PD supports advancing to higher doses to potentially deepen and prolong clinical response

24 Key differentiators of CNTY - 101 in autoimmune disease treatment CNTY - 101: CD - 19 targeted iNK cell therapy with 6 precision gene edits including Allo - Evasion TM technology • Currently being studied in Ph1 ELiPSE - 1 trial in R/R NHL • Ph1 CALiPSO - 1 trial in SLE initiating in H1 2024 Key differentiators in AID: (1) Allogeneic (2) NK cells (3) Allo - Evasion TM NK cells Allogeneic Allo - Evasion TM • Killing potency ≥ primary CAR - T • Trafficking to secondary lymphoid tissues and marrow favors pathogenic B - cell targeting • Limited in vivo expansion • Available “off - the - shelf” • No patient apheresis required • No manufacturing wait time • Platform enables lower COGs than donor - derived or autologous • Avoiding host immune rejection • Ability to repeat dose without continued lymphodepletion • Ability to retreat, if needed Tighter control over drug exposure: B - cell depletion without prolonged B - cell aplasia

25 CNTY - 101: Potential to drive B - cell depletion with tighter control over drug exposure More potent than primary CAR - T at B - cell killing in preclinical comparison CNTY - 101 more potent than primary CAR - T cells at B - cell killing at 24 hours in preclinical comparison Isolated B cells or CD19+ target cells were co - cultured with CNTY - 101 or primary CAR - T at several E:Ts in 96 - well U bottom plate s in NKCM with assay harvested at 24h. Assay plates were harvested and stained for Fixable Live/Dead. Cells were fixed and run on cytometer to determine Target+Dead Cell populations.
