NEW YORK, March 19, 2026 (GLOBE NEWSWIRE) -- Cellectis (the “Company”) (Euronext Growth: ALCLS - NASDAQ: CLLS), a clinical-stage biotechnology company using its pioneering gene editing platform to develop life-saving cell and gene therapies, today provided financial results for the fourth quarter and full year 2025, ending December 31, 2025 and provided a business update.
“Lasme-cel demonstrated a potentially transformative efficacy profile in one of oncology’s most challenging settings, achieving 100% overall response rate in the target Phase 2 population. Critically, lasme-cel converted all patients in the target population into transplant-eligible candidates. The pivotal Phase 2 is now enrolling, and with a BLA submission anticipated in 2028, lasme-cel is on a clear regulatory path to potentially becoming the first off-the-shelf CAR-T therapy to address this high unmet medical need” said André Choulika, Ph.D., Co-Founder and Chief Executive Officer of Cellectis. “With interim Phase 2 data for lasme-cel in r/r B-ALL, and full Phase 1 data for eti-cel in r/r NHL, both expected in Q4 2026, we are entering an important year for Cellectis, as we advance our ambition to bring life-saving off-the-shelf CAR-T therapies to patients who have run out of options”.
________________________________
1 Cash, cash equivalents and fixed-term deposits include restricted cash of $4.4 million as of December 31, 2025 classified as current and non-current financial assets and fixed-term deposits of $144.8 million as of December 31, 2025, classified as current financial assets.
Allogeneic CAR-T Pipeline
Lasme-cel in relapsed or refractory B-cell acute lymphoblastic leukemia (r/r B-ALL) - BALLI-01
- In October 2025, Cellectis presented full Phase 1 lasme-cel clinical data at the Cellectis’ R&D Day. The presented data position lasme-cel as a potentially game-changing therapy for patients with r/r B-ALL. Data highlighted:
Strong efficacy:
- 68% overall response rate (ORR) with lasme-cel Process 2, manufactured internally (n=22)
- 83% ORR at the recommended Phase 2 dose (RP2D) (n=12)
- 100% ORR in the target Phase 2 population (n=9)
In the target Phase 2 population, the complete response or complete remission with incomplete hematology recovery (CR/Cri) rate was 56%, with approximately 80% of these patients achieving minimum residual disease (MRD)-negative status
Favorable safety profile:
- Low rates of ≥ grade 3 cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS) at 2.5% and 5% respectively
Transplant eligibility in target Phase 2 population:
- All patients became eligible for transplant
Strong survival benefit:
- 14.8 months median overall survival (OS) in patients who achieved MRD-negative CR/CRi
The first interim analysis for the pivotal Phase 2 of the BALLI-01 trial is expected in Q4 2026 (n=40). Cellectis anticipates submitting a Biologics License Application (BLA) in 2028.
Eti-cel in relapsed or refractory non-Hodgkin lymphoma (r/r NHL) – NATHALI-01
- In December 2025, Cellectis presented encouraging Phase 1 preliminary data of eti-cel at the American Society of Hematology (ASH) annual meeting. The data showcased the potential of eti-cel in r/r NHL patients who have relapsed following multiple lines of therapy including, for 93% of patients, an autologous CD19 CAR-T, with an 88% ORR and 63% CR at the current dose level (n=8).
- Cellectis is initiating patient enrollment in the cohort with low dose interleukin-2 (IL-2) support to evaluate the potential to further enhance the already high response rates and durability of response in patients with r/r NHL.
- Cellectis expects to present the full Phase 1 dataset in 2026, including results from the IL-2 combination.
Circular single-stranded DNA (cssDNA) as a non-viral template for gene therapy
- In November 2025, Cellectis published a Nature Communications article establishing cssDNA as a highly efficient non-viral DNA donor template, for gene insertion in hematopoietic stem and progenitor cells (HSPCs).
While viral vectors such as AAV6 are commonly used for gene insertion, they raise safety and efficacy concerns. Over the past decade, non-viral DNA templates delivery has emerged as promising alternatives.
Cellectis’ research results mark a pivotal advance toward next-generation non-viral cell and gene therapies.
Key findings:
- Superior efficiency: cssDNA achieved over 40% knock-in efficiency, outperforming linear DNA by 3-5 times.
- Versatility: the process successfully targets multiple loci in HSPCs and primary T cells.
- Better persistence: in murine models, cssDNA-edited cells showed superior engraftment and edit maintenance compared to AAV6-edited cells.
TALE base editors (TALEB) safety and precision
- At ESGCT 2025, Cellectis presented a comprehensive safety study on TALE base editors (TALEB), which enable precise C-to-T DNA editing without causing double-strand breaks.
Key study highlights:
- Safety assessment: researchers used advanced bioinformatics and experimental models to track potential off-target effects in the nuclear genome of primary T cells.
- No bias detected: the study found no evidence of unintended editing at CTCF binding sites, which are critical for genome organization and gene expression.
These research results provide a strong framework for the safe development of TALEB in therapeutic cell engineering, supporting their potential for future nuclear and mitochondrial applications.
Partnerships
AstraZeneca – Joint Research and Collaboration Agreement
- Activities are progressing under the Joint Research and Collaboration Agreement with AstraZeneca, which leverages Cellectis’ gene editing expertise and manufacturing capabilities to develop up to 10 novel cell and gene therapy products for areas of high unmet medical need, including oncology, immunology and rare genetic disorders.
Servier (through its sublicensee Allogene) – Anti-CD19 CAR-T
- Under the Servier Agreement, Cellectis is eligible to up to $340 million in development and sales milestones as well as low double-digit royalties on sales.
- In December 2025, an arbitral tribunal has issued its decision in the arbitration proceedings against Les Laboratoires Servier and Institut de Recherches Internationales Servier IRIS SARL (“Servier”), relating to the License, Development and Commercialization Agreement entered into between Servier and Cellectis on March 6, 2019, as amended (the “Servier Agreement”). The Tribunal ruled on a partial termination of the License Agreement with respect to product UCART19 V1 (also referred to as “ALLO-501” by Allogene) and provided that Cellectis shall, at Allogene’s request, engage in good-faith discussions regarding the granting of a direct license to product UCART19 V1. All other claims brought by the parties were dismissed.
Allogene – Anti-CD70 CAR-T
- According to Allogene, the TRAVERSE trial in renal cell carcinoma has completed enrollment in its Phase 1b cohort, and Allogene is currently exploring partnering opportunities to advance the asset.
Iovance
- According to Iovance, new data across several pipeline programs is anticipated throughout 2026, including a Phase 1/2 trial investigating IOV-4001, a PD-1 inactivated TIL therapy, in previously treated advanced melanoma and NSCLC.
Corporate
Annual Shareholders Meeting
- On June 26, 2025, Cellectis held a Shareholders General Meeting. At the meeting, during which approximately 57% of voting rights were exercised, resolutions 1 through 23 and resolutions 25 and 26 were adopted, while resolution 24 was rejected, consistent with the recommendations of the Board of Directors. The detailed results of the vote and the resolutions are available on Cellectis’ website: https://www.cellectis.com/en/investors/general-meetings/
Board composition
- The Cellectis Shareholders' Meeting appointed Mr. André Muller as a director of the Company's Board of Directors. At the close of this meeting, the term of Mr. Axel-Sven Malkomes expired, and the previously announced resignation of Mr. Pierre Bastid became effective. In connection with these changes to the Board of Directors, the Board of Directors appointed Mr. André Muller, Dr. Donald Bergstrom, and Dr. Rainer Boehm as the members of the Company’s Audit Committee.
2025 Financial Results
Cash: As of December 31, 2025, Cellectis had $211 million in consolidated cash, cash equivalents, restricted cash and fixed-term deposits classified as current-financial assets. The Company believes its cash, cash equivalents, and fixed-term deposits will be sufficient to fund its operations into H2 2027.
This compares to $264 million in consolidated cash, cash equivalents, restricted cash and fixed-term deposits classified as current-financial assets as of December 31, 2024. This $53 million change includes $36.9 million of cash-in from our revenue, $8.4 million of interest received from our financial and cash-equivalent investments, $2.2 million cash-in from R&D tax credit, $3.2 million cash-in from VAT credit payments, and a $4.8 million foreign currency translation impact offset by cash payments from Cellectis to suppliers of $50.5 million, Cellectis’ wages, bonuses and social expenses paid of $40.0 million, the payments of lease debts of $10.8 million, the repayment of the Prêt Garanti par l’Etat (PGE) loan for $5.4 million and the payments of capital expenditures for $3.5 million.
We currently foresee focusing our cash spending at Cellectis in supporting the development of our pipeline of product candidates, including the manufacturing and clinical development expenses of lasme-cel, eti-cel and potential new product candidates, and operating our state-of-the-art manufacturing capabilities in Paris (France) and Raleigh (North Carolina).
Revenues and Other Income: Consolidated revenues and other income were $79.6 million for the year ended December 31, 2025 compared to $49.2 million for the year ended December 31, 2024. This $30.4 million increase between the years ended December 31, 2024 and 2025 is mainly driven by the evolution of activities performed in connection with the research plans and fulfillment of our performance obligations under the Joint Research and Collaboration Agreement signed with AstraZeneca. Revenues as recorded in the year ended December 31, 2024 included a $5.4 million development milestone under the License Agreement signed with Servier.
R&D Expenses: Consolidated R&D expenses were $93.5 million for the year ended December 31, 2025, compared to $90.5 million for the year ended December 31, 2024. This $3.0 million increase is mainly due to (i) a $4.2 million increase in personnel expenses driven by an evolution of our R&D headcount consistent with our roadmap, higher fair market value of stock-based compensation instruments due to underlying stock dynamics, and foreign exchange effects; (ii) a $0.3 million increase in depreciation and amortization; compensated by (iii) a $1.5 million decrease in purchases and external expenses.
SG&A Expenses: Consolidated SG&A expenses were $19.8 million for the year ended December 31, 2025 compared to $19.1 million for the year ended December 31, 2024. The $0.7 million change is mainly due to a $0.6 million increase in purchases and external expenses.
Other operating income and expenses: Other operating income and expenses decreased slightly by $0.2 million between the years ended December 31, 2024 and 2025, from $0.8 million in 2024 to $0.6 million in 2025.
Net financial gain (loss): Net financial loss was $34.9 million for the year ended December 31, 2025, compared to a $22.8 million net financial gain for the year ended December 31, 2024. This $57.7 million difference reflects mainly a $28.3 million decrease in financial income and a $29.5 million increase in financial expenses between the years ended December 31, 2024 and 2025.
The decrease in financial income is mainly attributable to (i) a $14.3 million gain in change in fair value of the derivative instrument component of the SIA, which was recorded last year before derecognition of the derivative in May 2024; (ii) a $7.2 million decrease in foreign exchange gains; (iii) a $1.8 million decrease in income from cash, cash equivalents and financial assets in line with the evolution of interest rates in 2025, (iv) a $ 5.7 million gain recognized in the year ended December 31, 2024 on the fair value measurement of the Tranches A, B and C warrants issued to the European Investment Bank ("EIB"), partially offset by (v) a $0.8 million increase in FX derivatives fair value gains.
The increase in financial expenses is mainly attributable to a (i) $22.2 million increase in foreign exchange loss over the period due to the devaluation of the USD against the Euro, (ii) a $14.7 million loss on the fair value measurement of the Tranches A, B and C warrants issued to the EIB, (iii) a $0.7 million increase in interest on our financial and lease liabilities, partially offset by (iv) a $7.8 million decrease in the loss on fair value measurement of our investment in shares of Cibus which was entirely sold in Q1 2025.
Net Income (loss) Attributable to Shareholders of Cellectis: Consolidated net loss attributable to shareholders of Cellectis was $67.6 million (or a $0.67 loss per share) for the year ended December 31, 2025, compared to a $36.8 million loss (or a $0.41 loss per share) for the year ended December 31, 2024. The $30.8 million change in net loss was primarily driven by (i) a $30.4 million increase in revenues and other income, offset by (ii) a $3.9 million increase in operating expenses and other operating income and (iii) a $57.7 million change from a net financial gain of $22.8 million as of December 31, 2024 to a net financial loss of $34.9 million as of December 31, 2025.
Adjusted Net Income (Loss) Attributable to Shareholders of Cellectis: Consolidated adjusted net loss attributable to shareholders of Cellectis was $61.5 million (or a $0.61 loss per share) for the year ended December 31, 2025, compared to a net loss of $33.6 million (or a $0.37 loss per share) for the year ended December 31, 2024.
The year-end consolidated financial statements of Cellectis have been prepared in accordance with International Financial Reporting Standards, as issued by the International Accounting Standards Board (“IFRS”).

Note Regarding Use of Non-IFRS Financial Measures
Cellectis S.A. presents adjusted net income (loss) attributable to shareholders of Cellectis in this press release. Adjusted net income (loss) attributable to shareholders of Cellectis is not a measure calculated in accordance with IFRS® Accounting Standards. We have included in this press release a reconciliation of this figure to net income (loss) attributable to shareholders of Cellectis, which is the most directly comparable financial measure calculated in accordance with IFRS Accounting Standards.
Because adjusted net income (loss) attributable to shareholders of Cellectis excludes non-cash stock-based compensation expense — a non-cash expense, we believe that this financial measure, when considered together with our IFRS financial statements, can enhance an overall understanding of Cellectis’ financial performance. Moreover, our management views the Company’s operations, and manages its business, based, in part, on this financial measure. In particular, we believe that the elimination of non-cash stock-based expenses from Net income (loss) attributable to shareholders of Cellectis can provide a useful measure for period-to-period comparisons of our core businesses. Our use of adjusted net income (loss) attributable to shareholders of Cellectis has limitations as an analytical tool, and you should not consider it in isolation or as a substitute for analysis of our financial results as reported under IFRS. Some of these limitations are: (a) other companies, including companies in our industry which use similar stock-based compensation, may address the impact of non-cash stock- based compensation expense differently; and (b) other companies may report adjusted net income (loss) attributable to shareholders or similarly titled measures but calculate them differently, which reduces their usefulness as a comparative measure. Because of these and other limitations, you should consider adjusted net income (loss) attributable to shareholders of Cellectis alongside our IFRS financial results, including Net income (loss) attributable to shareholders of Cellectis.
