"Through this first quarter of 2026, our company has continued to demonstrate focused execution of the strategic priorities we set forth late last year." stated Kris Vaddi, Ph.D., Chief Executive Officer of Prelude. "Since the beginning of this year, we’ve advanced PRT12396 into first-in-human studies, presented promising preclinical data from our highly selective KAT6A degrader development candidate, continued to progress towards a development candidate from our mCALR program and importantly, extended our cash runway into the second quarter of 2028."

Program Updates and Upcoming Milestones

Mutant selective JAK2V617F JH2 inhibitor program

JAK2V617F is the primary driver mutation responsible for disease progression in the majority of patients living with myeloproliferative neoplasms (MPNs). The mutation impacts approximately 95% of patients with polycythemia vera (PV), 60% of patients with essential thrombocythemia (ET) and 55% of patients with myelofibrosis (MF). Identifying JAK2 JH2 inhibitors that selectively target V617F+ cells has long been the goal for advancing the treatment of MPNs.

Prelude has designed and identified novel allosteric inhibitors that bind into the JAK2 JH2 "deep pocket" where the V617F mutation resides. These candidates demonstrate mutant specific inhibition in multiple preclinical models of MPNs. Prelude believes this approach may have the potential to reduce mutant allele burden, slow or even reverse disease progression, and transform treatment outcomes for MPN patients.

PRT12396, Prelude’s lead, mutant-selective JAK2V617F inhibitor received IND clearance from the U.S. Food and Drug Administration, as previously announced in February 2026 and recently initiated and commenced enrollment into a Phase 1 study of PRT12396 in patients with PV and MF.

The JAK2V617F inhibitor program is subject to an exclusive option agreement with Incyte announced in November 2025.

Highly selective KAT6A oral degrader program

KAT6 is an emerging and recently validated target in the treatment of ER+ breast cancer. Prelude discovered and is developing first-in-class, highly potent, highly selective and orally bioavailable KAT6A selective degraders. The Company has selected a development candidate, PRT13722 and remains on track to file an IND application in mid-2026, and pending clearance, phase 1 study initiation expected in the 2nd half of 2026. Prelude believes that selectively degrading KAT6A has the potential for improved efficacy, tolerability and combinability with other agents relative to non-selective inhibitors of KAT6A/B.

The Company presented preclinical data supporting this hypothesis at the AACR (Free AACR Whitepaper) Annual Meeting 2026. The presentation can be found at Publications – Prelude Therapeutics.

Degrader payloads for next generation DACs

Prelude is leveraging our expertise in targeted protein degradation to discover and develop novel degrader payloads for use with next generation DACs. We have developed highly potent SMARCA2/4 and CDK9 degrader payloads optimized for efficacy, tolerability and developability when coupled to a wide range of different antibodies. Building on our existing DAC partnership with AbCellera, the Company’s payloads and corresponding payload-linkers are available for licensing to additional partners to expand the reach of this new technology.

We have recently published preclinical data demonstrating that next generation DACs using Prelude degrader payloads have potential for significantly better in vivo efficacy and tolerability compared to traditional cytotoxic ADCs when tested head-to-head in xenograft models. These data can be found at: Publications – Prelude Therapeutics

Mutated calreticulin (mCALR) DAC discovery program

Mutant CALR is a neoantigen presented on the cell surface of malignant myeloid cells but not normal cells and is found in approximately 25-35% of patients with MF and essential thrombocythemia (ET). Recently, a mCALR-targeted monoclonal antibody demonstrated robust clinical activity in high-risk ET patients. Prelude is exploring mCALR-targeted DACs using the Company’s proprietary degrader payloads as a differentiated approach for patients with CALR mutations. This early discovery program is wholly owned and controlled by Prelude.

The Company presented the preclinical data from the program at the European Hematology Association (EHA) (Free EHA Whitepaper) 2025 Congress in June and the American Society of Hematology (ASH) (Free ASH Whitepaper) 67th Annual Meeting in December 2025. The presentations can be found at Publications – Prelude Therapeutics.

First Quarter 2026 Financial Results 

Cash, Cash Equivalents, Restricted cash and Marketable securities:

Cash, cash equivalents, restricted cash and marketable securities as of March 31, 2026 were $84.8 million. Subsequent to March 31, 2026, the Company completed an underwritten offering with gross proceeds of approximately $90 million. Based on preliminary estimates, the Company anticipates that its existing cash, cash equivalents, restricted cash and marketable securities will fund Prelude’s operations into the second quarter of 2028.

Research and Development (R&D) Expenses:

For the three months ended March 31, 2026, R&D expense decreased to $13.6 from $28.8 million for the prior year period. Included in the R&D expense for the three months ended March 31, 2026 was $1.1 million of non-cash expense related to stock-based compensation expense, including employee stock options, compared to $2.3 million for the three months ended March 31, 2025. Along with the decrease in stock-based compensation expense, the decrease was primarily related to lower expense incurred for our SMARCA2 clinical trials which we paused in 2025. Research and development expenses may fluctuate from period to period depending upon the stage of certain projects and the level of preclinical and clinical trial-related activities.

General and Administrative (G&A) Expenses:

For the three months ended March 31, 2026, G&A expenses decreased to $5.2 million from $5.8 million for the prior year period. Included in general and administrative expenses for the threemonths ended March 31, 2026, was $0.9 million of non-cash expense related to stock-based compensation expense, including employee stock options, compared to $1.6 million for the three months ended March 31, 2025. The decrease in general and administrative expenses was primarily due to a decrease in stock-based compensation along with a decrease in employee-related expenses.

Net Loss:

For the three months ended March 31, 2026, net loss was $10.4 million, or $0.13 per share compared to $32.1 million, or $0.42 per share, for the prior year period. Included in the net loss for the three months ended March 31, 2026, was $2.0 million of non-cash expenses related to the impact of expensing share-based payments, including employee stock options due in part to fewer employees, as compared to $3.8 million for the same period in 2025.

The abstract, titled "Bispecific CD3xCD28 Antibody-LNPs Drive In Vivo CAR-T Cell Generation with Deep B-Cell Depletion," highlights preclinical studies showing B-cell depletion in blood and lymphoid tissues, including spleen, bone marrow, and lymph nodes. Activity was confirmed in both humanized mouse and non-human primate models.

By combining CD3 with CD28 costimulatory engagement, the technology enables efficient T-cell transfection, activation, and functional CAR-T cell generation directly in vivo. The antibody-conjugated LNP directs cell-specific gene delivery, and the mRNA nature of the platform, obviates the need for pre-conditioning chemotherapy while allowing for repeat dosing, leading to expansion and persistence of functional memory T-cell populations.

"These data demonstrate the strength of our in vivo targeting technology," said John Mascola, M.D., Chief Scientific Officer of ModeX Therapeutics. "Our antibody-conjugated LNP platform offers a simple and versatile approach to gene delivery for immune cells in vivo, and has the potential to simplify treatment access by eliminating the burden of ex vivo manufacturing."

"Our targeted gene delivery platform uses proprietary ModeX technology to generate CAR-T cells directly in patients," said Gary Nabel, M.D., Ph.D., President and Chief Executive Officer of ModeX Therapeutics. "It offers a promising clinical modality for diverse diseases, including autoimmunity and oncology."

"We continued to meaningfully advance our pipeline of novel therapies focused on transforming the metastatic breast cancer treatment paradigm during the first quarter, with top-line data from our Phase 3 OPERA-01 trial of palazestrant as a monotherapy expected this fall and initial Phase 1 clinical data for OP-3136 being presented at ASCO (Free ASCO Whitepaper) later this month," said Sean P. Bohen, M.D., Ph.D., President and Chief Executive Officer of Olema Oncology. "We continued patient enrollment in OPERA-02, our Phase 3 trial of palazestrant in combination with ribociclib in the frontline metastatic setting, while advancing our ongoing Phase 1/2 combination studies evaluating palazestrant as a potential combination endocrine therapy of choice for metastatic breast cancer. With important clinical data catalysts on the horizon this year, we believe that we are well-positioned to continue our transformation into a fully integrated oncology company with our first anticipated commercial launch next year."

Recent Progress

Presented two preclinical posters at the 2026 American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting in April:
The first demonstrated that palazestrant fully recruits the corepressor protein, NCoR1, in vitro, supporting complete estrogen receptor antagonism.
The second reinforced that palazestrant in combination with OP-3136 drives synergistic anti-tumor activity in in vivo estrogen receptor-positive, human epidermal growth factor receptor 2-negative (ER+/HER2-) breast cancer models.
Continued enrollment in the pivotal Phase 3 OPERA-02 trial evaluating palazestrant in combination with ribociclib in frontline ER+/HER2- advanced or metastatic breast cancer.

First Quarter 2026 Financial Results
Cash, cash equivalents, and marketable securities as of March 31, 2026, were $505.3 million.

Net loss for the quarter ended March 31, 2026 was $53.1 million, as compared to $30.4 million for the quarter ended March 31, 2025. The increase in net loss for the first quarter was related to higher spending on clinical development and research and corporate-related activities related to late-stage clinical trials for palazestrant and the advancement of OP-3136.

GAAP research and development (R&D) expenses were $49.2 million for the quarter ended March 31, 2026, as compared to $30.6 million for the quarter ended March 31, 2025. The increase in R&D expenses was primarily related to increased spending on clinical development-related activities as we continue to advance palazestrant through late-stage clinical trials and OP-3136 in early-stage clinical studies, and increased personnel-related costs, including an increase in non-cash stock-based compensation expense of $3.3 million, mainly due to higher grant prices in 2026 and higher headcount.

Non-GAAP R&D expenses were $42.7 million for the quarter ended March 31, 2026, excluding $6.6 million non-cash stock-based compensation expense. Non-GAAP R&D expenses were $27.3 million for the quarter ended March 31, 2025, excluding $3.3 million non-cash stock-based compensation expense. A reconciliation of GAAP to non-GAAP financial measures used in this press release can be found at the end of this press release.

GAAP G&A expenses were $8.8 million for the quarter ended March 31, 2026, as compared to $4.2 million for the quarter ended March 31, 2025. The increase in G&A expenses was primarily due to higher corporate-related costs, and personnel-related costs, including an increase in non-cash stock-based compensation expense of $2.5 million, mainly due to higher grant prices in 2026.

Non-GAAP G&A expenses were $5.2 million for the quarter ended March 31, 2026, excluding $3.6 million non-cash stock-based compensation expense. Non-GAAP G&A expenses were $3.2 million for the quarter ended March 31, 2025, excluding $1.1 million non-cash stock-based compensation expense. A reconciliation of GAAP to non-GAAP financial measures used in this press release can be found at the end of this press release.

"Putting patients first and providing access to care in a familiar setting close to home matters" said Paul J. Hastings, Chief Executive Officer of Nkarta. "In early April, we reached agreement with the FDA to amend our protocol to allow outpatient dosing in community settings as well as the option to re-dose patients if needed, the removal of overnight monitoring requirements, and the expansion of the Ntrust-2 study to include patients with rheumatoid arthritis. IRB approval of our protocol amendments has been secured across multiple sites, with additional approvals underway. These advancements will enable us to expand patient access beyond urban hubs and major academic centers by engaging community research centers and local rheumatology practices in the neighborhoods where most patients live. We look forward to providing our initial dataset in 2026."

NKX019 Clinical Program Progress and Upcoming Milestones

Enrollment continues across Ntrust-1 and Ntrust-2, our multi-center, open-label, dose-escalation clinical trials evaluating NKX019 in multiple autoimmune diseases.
IRB approval of our protocol amendments has been secured across multiple sites on outpatient dosing, re-dosing, ending overnight monitoring, and adding RA to Ntrust-2.
Patients are being dosed at 4 billion cells per dose x 3 doses (12 billion cells total) across all indications in Ntrust-1 and Ntrust-2.
Initial clinical data from Ntrust-1 and Ntrust-2 are planned for presentation at a medical conference in 2026.

About the Ntrust℠ Clinical Trials in Autoimmune Disease
Ntrust-1 (NCT06557265) and Ntrust-2 (NCT06733935) are multi-center, open label, dose escalation clinical trials in patients with autoimmune disease receiving lymphodepletion followed by CD19-targeted CAR-NK cell therapy. Both trials will assess the safety of NKX019 in people living with autoimmune diseases as well as its potential to achieve durable remission via a "reset" of the immune system through the elimination of pathogenic B cells.

The Ntrust trials are enrolling up to 12 patients per dose level per disease indication across systemic sclerosis, idiopathic inflammatory myopathy, ANCA-associated vasculitis, rheumatoid arthritis, lupus nephritis, and primary membranous nephropathy. Additional participants may be enrolled if needed to refine patient populations for further study.

In both studies, patients now receive a three-dose cycle of NKX019 on Days 0, 3, and 7 following lymphodepletion with fludarabine and cyclophosphamide or cyclophosphamide alone, if they have significant cytopenia at baseline. Leveraging the engineering of NKX019, no patients in either trial will receive supplemental cytokines or antibody-based therapeutics. This approach is designed to evaluate the single-agent activity of NKX019 and facilitate a more rapid path to regulatory approval. Patients in Ntrust-1 may also receive additional cycles, if needed, to restore response or enable a deeper response.

About NKX019
NKX019 is an allogeneic, cryopreserved, off-the-shelf immunotherapy candidate that uses natural killer (NK) cells derived from the peripheral blood of healthy adult donors. It is engineered with a humanized CD19-directed chimeric antigen receptor (CAR) for enhanced cell targeting and a proprietary, membrane-bound form of interleukin-15 (IL-15) for greater persistence and activity without exogenous cytokine support. CD19 is a biomarker for normal B cells as well as those implicated in autoimmune disease. Nkarta is evaluating NKX019 in multiple autoimmune conditions.
