## Exhibit 99.1

**EXHIBIT 99.1**

**Legend Biotech Announces Late-Breaking Oral Presentation at EHA 2026 Showcasing Initial Phase 1 In Vivo CAR-T Data with LB2501 in Non-Hodgkin Lymphoma (NHL)**

* *Promising Phase 1 data for LB2501, a potential first-in-class CD19/CD20 dual-targeting in vivo CAR-T therapy, as an off-the-shelf, single-infusion treatment for B-cell malignancies*

* *An ORR of 100% (6/6) was observed in the dose level 2 cohort, including CR rate of 83.3% (5/6) in patients with relapsed/ refractory NHL*

* *Data demonstrate robust in vivo CAR*-*T expansion without lymphodepleting chemotherapy* 

* *Favorable safety profile: no DLTs, no SAEs, no ICANS, CRS <u><</u>Grade 2* 

BRIDGEWATER, N.J., June 02, 2026 (GLOBE NEWSWIRE) -- Legend Biotech Corporation (NASDAQ: LEGN) (Legend Biotech or the Company), a global leader in cell therapy, today announced that promising preliminary clinical data for LB2501, its investigational *in vivo* CD19/CD20 dual-targeting CAR-T cell therapy, in patients with relapsed/refractory B-cell non-Hodgkin lymphoma (R/R B-NHL), will be presented during a late-breaking session at the European Hematology Association (EHA) 2026 Congress, taking place June 11-14, 2026, in Stockholm, Sweden.

"The upcoming presentation of Phase 1 LB2501 data in patients with B-cell malignancies represents an important step in advancing *in vivo* CAR-T approaches," said Ying Huang, Ph.D., Chief Executive Officer of Legend Biotech. "By generating CAR-T cells directly within the patient, this approach has the potential to simplify treatment delivery and expand access for patients who may not be able to receive traditional CAR-T cell therapies. LB2501 is built on the TaVec™ platform, which is a proprietary lentiviral vector engineered to enhance T-cell specificity, transduction efficiency, and safety, while restricting transduction of non-T cells."

**LB2501: Promising Phase 1 Trial of *In Vivo* CAR-T Data Demonstrate High Response Rates in B-cell Malignancies**

Data from 12 patients across two dose cohorts in an ongoing Phase 1 study evaluating LB2501 in patients with R/R B-NHL provide early clinical evidence supporting the potential of an *in vivo* CAR-T approach in B-cell malignancies. LB2501 is designed to generate CAR-T cells directly within the patient following a single intravenous infusion, eliminating the need for cell manufacturing and lymphodepletion.

As of April 1, 2026, 12 patients with R/R B-NHL were treated across two dose levels (DL1 and DL2). Additional details will be presented at EHA 2026. Key findings from the abstract include:

**Efficacy Results**

* At DL2 (median follow-up for DL2 was 2.2 months [range, 2.0 to 3.8]) Objective response rate (ORR): 100% (6/6)Complete response rate (CR): 83.3% (5/6)All responses were ongoing at data cutoff 

**Pharmacokinetics** 

* Dose-dependent *in vivo* CAR-T expansion observed

* CAR-T cells detected in peripheral blood for up to 116 days

**Safety Results**

* No dose-limiting toxicities (DLTs), serious adverse events (SAEs), or deaths were observed

* Infusion-related reactions occurred in 75% of patients, all of which were ≤ Grade 2

* Cytokine release syndrome (CRS) occurred in 66.7% of patients, all of which were ≤ Grade 2

* No immune effector cell-associated neurotoxicity syndrome (ICANS) was reported

* Grade ≥3 lentiviral vector-related and CAR-T-related adverse events were limited to decreased lymphocyte count and decreased neutrophil count

**Background**

Ex vivo CAR-T therapies have advanced treatment for relapsed/refractory non-Hodgkin lymphoma (R/R NHL) but are limited by complex manufacturing and lymphodepletion. In vivo CAR-T offers an off-the-shelf alternative that generates CAR-T cells directly in patients without requiring lymphodepletion. While feasibility has been shown in multiple myeloma, clinical data for B-cell malignancies remain unreported. LB2501, a third-generation, replication-incompetent lentiviral vector (LVV) pseudotyped with a modified fusion glycoprotein and a CD3 binder for T-cell-specific transduction, encodes a CD19/CD20 dual targeting CAR to generate CAR-T in vivo.

**Aims**

To evaluate the safety, pharmacokinetics, and preliminary efficacy of LB2501 in R/R B-NHL.

**Methods**

This ongoing phase 1 trial (NCT07002112) enrolled patients with measurable R/R NHL who had primary refractory disease or progression after ≥2 prior lines of therapy. A 3+3 dose-escalation design with backfilling was used across dose levels (DLs). LB2501 was administered as a single intravenous infusion without lymphodepletion.

**Results**

As of April 1, 2026, 12 patients had been dosed with LB2501 at DL1 (n=6) or DL2 (n=6). The median age was 58.5 years, median prior therapy lines was 3, and 58.3% were refractory to last line. Patients included 7 (58.3%) LBCL, 3 (25%) FL and 2 (16.7%) MCL. No DLT, SAE or fatal cases were reported. Infusion-related reactions occurred in 9 patients (75.0%); all were grade 1 or 2, resolved within a median of 2.0 days, and required no tocilizumab or glucocorticoids. Cytokine release syndrome (CRS) occurred in 66.7% patients (grade 1 in 58.3%, grade 2 in 8.3%); No neurotoxicity (ICANS) was observed. Grade≥3 LVV-related and CAR-T-related adverse events were limited to decreased lymphocyte count (33.3% each) and decreased neutrophil count (25.0% and 50.0%, respectively). The objective response rate (ORR) was 50% (6/12), with a complete response rate (CR) of 41.7% (5/12). At DL2, the ORR was 100% (6/6) and the CR was 83.3% (5/6). All responses were ongoing at cut-off date (Figure 1). The median follow-up for DL2 was 2.2 months (range, 2.0 to 3.8). PK analysis via qPCR confirmed dose-dependent in vivo CAR-T cell expansion in 83% (5/6) of patients at DL1 and 100% (6/6) at DL2. At DL2, the median Cmax was 109,117.5 copies/μg DNA (vs. 1,068.0 at DL1), with a median Tmax of 15.0 days. At the time of data cutoff, patients exhibited persistent PK, with CAR-T cells detectable in peripheral blood for up to 116 days. Insertion site analyses indicate in vivo transduction is highly T cell specific, polyclonal, and diverse with mostly single copy insertion per T cell. The median VCN for in vivo CAR-T was 1.05, lower than ex vivo manufactured CAR-T.

**Summary/Conclusion**

This study represents the initial clinical cohort of in vivo CAR-T therapy in relapsed/refractory non-Hodgkin lymphoma. LB2501, a first-in-class CD19/CD20 dual-targeting in vivo vector, introduces a novel paradigm by eliminating the need for ex vivo manufacturing and lymphodepletion. LB2501 has demonstrated a favorable safety profile and encouraging efficacy with a 100% ORR and 83.3% CR at DL2. While a longer-follow up is warranted, these data highlight the potential of LB2501 as a scalable, readily accessible "off-the-shelf" immunotherapy for B-cell malignancies.
