"While PI3Kα inhibition has demonstrated meaningful benefit in breast cancer, its use in the frontline setting has been limited by tolerability challenges with earlier agents," said Don Bergstrom, M.D., Ph.D., President of R&D at Relay Therapeutics. "We believe that combining the selective profiles of zovegalisib and atirmociclib with endocrine therapy has the potential to enable a well-tolerated, all-oral triplet regimen, and these initial data support advancing this combination into Phase 3 development for patients with frontline metastatic breast cancer."

Zovegalisib + Atirmociclib Data Demonstrate Potential Best-in-Class Triplet Profile

Zovegalisib is currently being evaluated in ReDiscover, an ongoing first-in-human study designed to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics and preliminary antitumor activity of zovegalisib in combination with fulvestrant and CDK inhibitors in patients with PI3Kα-mutated, HR+/HER2- metastatic breast cancer. These data are from the zovegalisib + atirmociclib + fulvestrant dose finding portion of the study.

As of the April 13, 2026 data cut-off date, 69 total patients were enrolled, with 62 patients at or below the potential Phase 3 dose and 34 patients with measurable disease evaluable for response. All patients had previously received a CDK4/6 inhibitor and at least one prior endocrine therapy in the advanced setting and could have received a PI3K pathway inhibitor. These heavily pre-treated patients had received a median of 2 prior therapies (21% received 3+ prior therapies) in the metastatic setting with 63% having visceral disease, 29% having received chemotherapy, and 47% being pre-diabetic. The median follow-up was 7.4 months.

Expansion cohorts of zovegalisib + atirmociclib + fulvestrant and zovegalisib + atirmociclib + aromatase inhibitor (AI) in the ReDiscover study are ongoing.

Safety and Tolerability of Triplet is Critical for Potential Long-Term Treatment in Frontline Endocrine Sensitive Breast Cancer

Early safety and tolerability data for zovegalisib in combination with atirmociclib and fulvestrant (N=62) reinforce the potential of this regimen moving forward in frontline endocrine sensitive patients. As of the April 13, 2026 data cut-off date:


Only two patients (3%) discontinued zovegalisib and six patients (10%) dose reduced zovegalisib due to treatment-related adverse events (TRAEs)

Adverse events were consistent with those previously reported by each molecule
o
Grade 3 hyperglycemia was 0% despite 47% of patients being pre-diabetic

Overall grade 3+ TRAE rate in these median third-line patients is 40%
o
Neutropenia accounts for the majority of the grade 3+ events
o
No instance of febrile neutropenia was observed

Overall Response Rate in Median Third Line Patients is Approaching ORR Seen in Frontline Breast Cancer with Standard of Care

As of the April 13, 2026 data cut-off date, 34 patients had measurable disease to be evaluated for response:


Objective response rate (ORR) was 44% (15/34) and was also 44% in both kinase and non-kinase patients
o
ORR in these heavily pre-treated patients has approached that of current standard of care doublets in 1L patients, ranging from 53% to 55% ORR
o
Nearly all patients experienced tumor reduction (85%, 29/34)

48 of 62 patients (77%) remain on study as of the data cut-off date, with a median follow-up of 7.4 months
o
The data are not yet mature enough to estimate median progression-free survival

Pharmacokinetics

Pharmacokinetic analyses demonstrated that atirmociclib increased the exposure of zovegalisib by about two and half-fold (regardless of atirmociclib dose), while zovegalisib had no impact on atirmociclib exposure. Subject to regulatory feedback, the potential Phase 3 dose of zovegalisib will be 150mg twice daily (BID), which maintains average concentration of zovegalisib just below IC90 throughout the dosing interval.

Preliminary Phase 3 Trial Design in Frontline Endocrine Sensitive Patients

The planned study, subject to regulatory feedback, is a randomized Phase 3 trial evaluating zovegalisib in combination with atirmociclib and aromatase inhibitor (AI) in frontline endocrine sensitive patients with PIK3CA-mutated, HR+/HER2- advanced or metastatic breast cancer.


Population: Frontline endocrine sensitive patients with HR-positive, HER2-negative advanced or metastatic breast cancer harboring a PIK3CA mutation

Experimental arm: Zovegalisib + atirmociclib + AI


Control arm: CDK4/6 inhibitor (investigator’s choice) + AI

Key endpoints: Median progression-free survival (primary) and overall survival (secondary)

Pfizer to Supply Atirmociclib and Palbociclib Through Supply Agreement

Pfizer has agreed to supply atirmociclib for the experimental arm in combination with zovegalisib and the palbociclib portion of the control arm for use in the planned study. Relay Tx will sponsor, fully operationalize and fund the planned Phase 3 trial. Relay Tx retains full global rights for zovegalisib.

Next Steps


Conduct regulatory interactions to finalize Phase 3 design and dose with the goal of initiating the study in early 2027

Continued execution of Phase 1/2 dose finding and expansion as part of the ReDiscover study, allowing for larger sample size and longer follow up at potential Phase 3 dose for future disclosures

Continued execution of ongoing ReDiscover-2 Phase 3 trial in second line breast cancer

Present initial data for zovegalisib in vascular anomalies at ISSVA 2026 (May 20, 2026 in Philadelphia)

About Zovegalisib

Zovegalisib is the lead program in Relay Therapeutics’ efforts to discover and develop mutant selective inhibitors of PI3Kα, the most frequently mutated kinase in all cancers and all vascular anomalies. Zovegalisib has the potential, if approved, to address a significant portion of the approximately 140,000 patients with HR+/HER2- breast cancer with a PI3Kα mutation and the estimated 170,000 patients with vascular anomalies driven by a PI3Kα mutation per year in the United States, one of the largest patient populations for a precision medicine.

Traditionally, the development of PI3Kα inhibitors has focused on the active, or orthosteric, site. The therapeutic index of orthosteric inhibitors is limited by the lack of clinically meaningful selectivity for mutant versus wild-type (WT) PI3Kα and off-isoform activity. Toxicity related to inhibition of WT PI3Kα and other PI3K isoforms results in sub-optimal inhibition of mutant PI3Kα with reductions in dose intensity and frequent discontinuation. The Dynamo platform enabled the discovery of zovegalisib, the first known allosteric, pan-mutant, and isoform-selective PI3Kα inhibitor, designed to overcome these limitations. Relay Therapeutics solved the full-length cryo-EM structure of PI3Kα, performed computational long time-scale molecular dynamic simulations to elucidate conformational differences between WT and mutant PI3Kα, and leveraged these insights to support the design of zovegalisib. Zovegalisib is currently being evaluated in multiple metastatic breast cancer studies and a first-in-human study designed to treat patients with PIK3CA (PI3Kα) mutation driven vascular anomalies.

Dror Ben-Asher, RedHill’s Chief Executive Officer, said: "2025 was not an easy year in our industry, but for RedHill it was a year that demonstrates our business tenacity, the strategic transactions that we successfully accomplished and the traction we have achieved in progressing key commercial, R&D and financial objectives. Through the partnership with Cumberland, we have transformed the Talicia business creating a strong new partnership powered to drive increased sales, strengthen our balance sheet and provide a platform for future growth and market expansion."

Mr. Ben-Asher continued: "We have carefully and intentionally focused our R&D pipeline: demonstrating opaganib’s potential to augment current standard of care therapies across multiple oncology indications; taking major steps in a ground-breaking new approach to Crohn’s disease, with the FDA providing positive feedback on RHB-204’s pathway to approval and signing breakthrough collaborations in MAP detection diagnostics; and driving the emergence of RHB-102 (Bekinda) as a potential answer to GLP-1/GIP-related nausea, vomiting and diarrhea – one of the biggest growth restrictors in the $100 billion GLP-1 market."

In summarizing 2025, Mr. Ben-Asher added: "We have unlocked significant opportunity for the Company through strategic transactions like the Cumberland partnership and the ex-North America licensing of RHB-102 (Bekinda) to Hyloris for up to $60 million in potential milestone payments plus royalties. We demonstrated our tenacity and clear adherence to our agreements in successfully winning and defending the New York Supreme Court’s more than $10.5 million ruling against Kukbo, making it now final and eligible for enforcement, though collection remains subject to future realization. We have ended the year better positioned than we started. Having reshaped the Talicia business, improved our balance sheet, transitioned to a leaner and optimized operational footprint and sharply focused our R&D efforts, we are now on stronger footing for further growth."

Financial results for the 12 months ended December 31, 20256

Following the Cumberland transaction in October 2025, RedHill’s direct Talicia commercial operations were transferred to Talicia Holdings Inc. ("THI"), a 70%-owned jointly controlled venture. As a result, those operations are presented as "discontinued operations" in RedHill’s 2025 financial statements for accounting purposes. The year-over-year comparison below is therefore presented on a continuing operations basis, which reflects RedHill’s non-Talicia activities only. RedHill’s ongoing economic participation in the Talicia franchise going forward is reflected separately as its share of results of the joint venture. Prior period results have been recast accordingly.

Revenues for the year ended December 31, 2025, were $0.3 million, generated from the Hyloris license for RHB-102 (Bekinda), compared to no revenues for the year ended December 31, 2024.

Research and Development Expenses for the year ended December 31, 2025, were $2.0 million, as compared to $1.6 million for the year ended December 31, 2024. The increase was mainly driven by costs related to clinical activities.

General, Administrative and Business Development Expenses for the year ended December 31, 2025, were $6.2 million, compared to $4.9 million for the year ended December 31, 2024. The increase was primarily attributable to legal expenses related to the Kukbo litigation.

Share of loss of joint venture for the year ended December 31, 2025, was $33 thousand, representing RedHill’s 70% share of the net loss of THI, the joint venture formed in September 2025 with Cumberland Pharmaceuticals. This reflects less than three months of THI’s activity post-closing. Under the joint commercialization agreement, THI is entitled to 50% of Cumberland’s net revenues from Talicia sales in the U.S., and RedHill participates in that economic activity through its 70% interest in THI.

Operating Loss for the year ended December 31, 2025, was $7.9 million, compared to Operating Loss of $6.5 million for the year ended December 31, 2024. The difference is primarily attributable to an increase in operating expenses, as detailed above.

Financial Expenses, net for the year ended December 31, 2025, were $0.1 million, compared to Financial Income, net of $6.8 million for the year ended December 31, 2024. The income recognized in the year ended December 31, 2024, was primarily driven by the revaluation of financial instruments, partially offset by other financing expenses.

Net loss from continuing operations was $8.1 million for the year ended December 31, 2025, compared to net income from continuing operations of $0.4 million for the year ended December 31, 2024. The change was primarily attributable to the absence of significant financial income recognized in 2024 from the revaluation of financial instruments, together with higher operating expenses in 2025.

Net income from discontinued operations was $7.7 million for the year ended December 31, 2025, compared to net loss from discontinued operations of $8.6 million for the year ended December 31, 2024. The change was primarily attributable to the gain recognized upon loss of control of THI in 2025, and a decrease in other operating expenses.

Total assets as of December 31, 2025, were $25.3 million, compared to $18.0 million as of December 31, 2024. The increase was primarily attributable to the Company’s investment in a joint venture as part of the Talicia Holdings transaction.

Total liabilities as of December 31, 2025, were $21.1 million, compared to $22.7 million as of December 31, 2024. The decrease was primarily attributable to a reduction in allowance for deductions from revenues and a decrease in derivative financial instrument liabilities, partially offset by an increase in lease liabilities.

Net Cash Used in Operating Activities for the year ended December 31, 2025, was $9.7 million, compared to $9.4 million for the year ended December 31, 2024. The cash used in operating activities was primarily directed toward settling pre-closing liabilities related to Movantik and other operational activities.

Net Cash Provided by Investing Activities for the year ended December 31, 2025, was $1.7 million, primarily related to the proceeds from the investment in a joint venture, compared to an immaterial amount used in investing activities for the year ended December 31, 2024.

Net Cash Provided by Financing Activities for the year ended December 31, 2025, was $7.3 million, primarily generated through equity offerings and exercise of certain warrants. Net Cash Provided by Financing Activities for the year ended December 31, 2024, was $8.4 million, primarily generated through equity offerings.

Cash Balance as of December 31, 2025, was $4.1 million5.

2025 Corporate, Commercial and R&D Highlights:

Corporate – opportunity unlocked:

In 2025, RedHill successfully completed several important strategic transactions and won a significant court case against Kukbo, unlocking significant opportunity across our business:

In October 2025 the Company announced it had secured a $4 million strategic investment and U.S. co-commercialization partnership deal with Cumberland Pharmaceuticals for Talicia. The $4 million investment, to acquire a 30% ownership stake in RedHill’s global Talicia business, is payable in two equal tranches, $2 million of which was paid at closing and $2 million to be paid within 12 months of execution of the definitive agreements. RedHill and Cumberland have also entered into an Exclusive Joint Commercialization Agreement for Talicia in the United States with an equal sharing of the product’s net revenues. Subsequent to this, in February 2026, the Company announced the full sales and operational launch of Talicia, by Talicia Holdings Inc. ("THI"), a RedHill and Cumberland jointly controlled operating entity with a 70/30 RedHill/Cumberland ownership, supporting accelerated market penetration and expanded reach. Cumberland and Apotex have since announced their planned strategic transaction to integrate Cumberland’s U.S branded business into Apotex.

Earlier, in February 2025, the Company announced another transaction, licensing RHB-102 (Bekinda) for commercialization worldwide, excluding North America, to Hyloris Pharmaceuticals for up to $60 million in potential milestone payments plus royalties. Under the terms of the deal, Hyloris paid RedHill an upfront payment and will pay up to $60 million in potential milestone payments, plus up to mid-20s percent royalties on revenues, contingent upon achieving specified commercial targets, in return for exclusive rights to develop and commercialize RHB-102 (Bekinda) across all indications and territories outside the United States, Canada and Mexico.

A third deal was signed in October 2025, amending the existing Middle East licensing agreement to expand Talicia’s entry into additional Middle East markets. Under the terms of the amendment, RedHill will receive $500,000 in guaranteed payments, including a $250,000 upfront payment and $250,000 in fixed payments due within 18 months, plus a minimum of $1.3 million in near-term potential milestone payments, as well as tiered royalties up to mid-teens percent on Talicia net sales. In August 2025, the Company had also announced receipt of licensing payments from the original Middle East agreement totaling $1.1 million.

In June 2025, the Company entered into an Any Market Purchase Agreement (the "Purchase Agreement") with Alumni Capital LP, a Delaware limited partnership (the "Purchaser"). Pursuant to the Purchase Agreement, the Company has the right, but not the obligation, to sell to the Purchaser, from time to time, up to $10,000,000 of American Depositary Shares ("ADSs"), each representing 10,000 ordinary shares ("Ordinary Shares"), par value NIS 0.01 per share, of the Company, subject to the terms and conditions set forth in the Purchase Agreement.

In November 2025, the Company also announced that the New York Supreme Court’s approximately $10.5 million summary judgment in favor of RedHill against Kukbo is now final and eligible for enforcement and foreign recognition, with no further appeal permissible following expiry of the appeal period. Collection of the award and associated legal fees and costs, which were also awarded to RedHill, remain subject to future realization, and no related receivable has been recognized in the financial statements.

Commercial – a transformed Talicia business:

Following the transaction with Cumberland, at the Talicia business level, which is distinct from RedHill’s 2025 continuing operations, Talicia generated net revenues of approximately $8.9 million in the U.S. in 2025 (including Cumberland’s post-closing net revenues), and approximately $1.9 million in ex-U.S. licensing, product supply and royalties. This included revenues under our October 2025 amendment to the Middle East licensing agreement, a deal worth potentially $1.8 million plus sales royalty payments.

In January 2025, eight million lives were covered with Humana’s addition of Talicia to its Medicare Part D Formulary. New data describing the foundations for Talicia’s FDA-approved label change to a more convenient three-times daily (TID) "breakfast, lunch, and dinner" dosing routine, supporting patient adherence, were published in the Journal of Clinical Pharmacology. Talicia remains the leading U.S. gastroenterologist-prescribed branded H. pylori therapy.

RedHill continues to pursue acquisition of additional commercial products through licensing or promotion transactions, asset purchases, joint ventures, acquisitions, mergers or other business combinations involving companies with rights to commercial GI and other relevant assets. The Company intends to pursue such opportunities in the United States and, if available, in other jurisdictions.

R&D – focused on new opportunities:

With multiple externally funded Government and non-governmental collaborations, RedHill’s pipeline provides new and exciting opportunities in major indications, with multiple oncological indications alongside Crohn’s disease, diabetes and obesity-related disorders, viral and other gastrointestinal uses:

Opaganib7:

A potentially broad acting, novel, oral, host-directed small molecule drug, with a demonstrated safety and efficacy profile, advancing in largely externally funded programs directed at multiple underserved oncology, viral, inflammatory and diabetes and obesity-related indications, with sizeable multi-billion-dollar markets:

A new approach in the $12 billion prostate cancer market:

Prostate cancer (PC) is the second most diagnosed cancer in the world, with around 1.5 million new cases per year, causing almost 400,000 deaths8. People with metastatic castrate-resistant prostate cancer (mCRPC) have few treatment options available to them.

In February 2025, the Company announced the initiation of a Bayer-supported Phase 2 study of opaganib in combination with Bayer’s darolutamide in mCRPC, evaluating the potentially enhancing effect of opaganib in patients with poor prognosis. In July 2025, the Company further announced initiation of recruitment and an expansion of recruiting sites.

The study will utilize a companion lipid biomarker test (PCPro) to select mCRPC patients who have a poor prognosis due to standard of care (SoC) treatment and who may benefit from an opaganib + darolutamide combination treatment approach. The primary endpoint will be improved 12-month radiographic progression-free survival (rPFS).

Additional opaganib oncology and other updates include:


In April 2026 two posters outlining data showing opaganib enhances efficacy of neuroblastoma chemotherapy combination and augments anti-tumor immunity in triple-negative breast cancer in preclinical studies were presented at the American Association of Cancer Research (AACR) (Free AACR Whitepaper) annual meeting. Orphan drug designation for opaganib was previously granted by FDA for neuroblastoma (opaganib has several such designations in multiple indications, with three in oncology)


Discussions for further development of opaganib in neuroblastoma ongoing with Penn State University, Beat Childhood Cancer and Apogee, with potential for priority review voucher


In December 2025, RedHill reported additional preclinical data that opaganib reduces venetoclax resistant cells in chronic lymphocytic leukemia (CLL)


Positive in vivo study results supporting the potential of opaganib therapy in diabetes and obesity-related disorders – a market projected to be worth approximately $100 billion within the next decade – were published in the journal Diabetes, Metabolic Syndrome and Obesity in an article entitled "Opaganib Promotes Weight Loss and Suppresses High-Fat Diet-Induced Obesity and Glucose Intolerance" 9.


Pre-clinical testing of opaganib in metabolic disease (Obesity, T2D and Fatty Liver Disease) following prior publication of promising results continues


Programs in Ebola, acute respiratory distress syndrome (ARDS, COVID-19 and Influenza continue to seek to address important markets worth multiple hundreds of millions of dollars

RHB-20410:

RHB-204 is a proprietary, fixed-dose oral capsule containing a combination of clarithromycin, rifabutin and clofazimine, at specific doses designed to safely and effectively treat Mycobacterium avium subspecies paratuberculosis-positive (MAP-positive)-related Crohn’s disease (CD). Unlike existing therapies that focus on symptom relief, RHB-204 is intended to target the possible root cause of Crohn’s disease, which is hypothesized to be caused by Mycobacterium avium subspecies paratuberculosis (MAP).

Patent protected until at least 2041, RHB-204 is a next-generation formulation of RHB-104, which successfully completed a Phase 3 study in Crohn’s disease, with an optimized formulation for the treatment of CD. It contains the same three antimicrobial agents with potent intracellular, anti-mycobacterial and anti-inflammatory properties, and with an optimized dosing profile, RHB-204 provides the potential for enhanced tolerability, safety and compliance with a 40% pill burden reduction. RHB-204 is supported by a strong foundation of clinical data from the positive safety and efficacy results achieved in the Phase 3 study of RHB-104 in CD, with its potential further demonstrated using mucosal healing imaging, considered to be the gold standard for efficacy evaluation in CD.

Paradigm shift in MAP-positive Crohn’s disease treatment approach

In March 2025, the Company announced its plans to advance its potentially groundbreaking late-stage RHB-204 Crohn’s disease program, building on statistically significant positive RHB-104 Phase 3 results. In July 2025, the Company further updated that it had received positive FDA feedback on the pathway to approval of RHB-204 for CD and had initiated two new collaborations with leading academic centers utilizing cutting-edge rapid and accurate MAP killing detection diagnostics – the lack of which has previously been a major barrier to advancing the Company’s novel anti-MAP Crohn’s disease program.

The planned innovative Phase 2 study of RHB-204 is expected to be the first clinical study in a specifically defined Mycobacterium avium subspecies paratuberculosis infected (MAP-positive) Crohn’s disease (CD) patient population. The study intends to utilize novel and decisive endpoints and imaging, allowing for a study design with a relatively small sample size.

RHB-204 builds upon RHB-104’s successful Phase 3 study, which successfully met its Phase 3 study primary and secondary endpoints demonstrating a statistically significant 64% improvement in efficacy versus standard of care. It also showed compelling mucosal healing data in CD patients who underwent colonoscopy. The inclusion of MAP-positive only patients in the planned study with RHB-204 is anticipated to demonstrate a more consistent benefit in the study population across all efficacy outcomes.

RedHill is actively pursuing funding opportunities and partnerships to advance this potential paradigm-shifting treatment.

RHB-102 (Bekinda)11 update:

RHB-102 (Bekinda) is a proprietary, advanced clinical-stage, once-daily, bimodal extended-release, oral tablet formulation of 5-HT3 antagonist, ondansetron, targeting oncology support, acute gastroenteritis and gastritis, IBS-D and GLP-1/GIP-associated gastrointestinal (GI) side effects.

Largely de-risked, RHB-102 (Bekinda) development is supported by published positive U.S. Phase 3 & 2 results in gastroenteritis/gastritis and diarrhea-predominant irritable bowel syndrome (IBS-D) respectively, a positive comparative PK clinical study as part of the oncology support (CINV/RINV) program12, plus decades of ondansetron clinical use (>22 million annual U.S. ER prescriptions)13

RHB-102 (Bekinda) is clinically aligned, if approved, to improve titration success and reduce the #1 cause of discontinuing diabetes & weight loss therapies like Mounjaro/Zepbound & Ozempic/Wegovy

Development is being planned under the accelerated FDA 505(b)(2) route of RHB-102 (Bekinda) as a once-daily oral therapy for GLP-1/GIP receptor agonist therapy-associated GI side effects.

>2% of Americans take GLP-1 receptor agonist drugs14 but estimates suggest up to 50% discontinue within 3 months15, potentially costing an estimated $35 billion in lost market value by 203016.

RHB-10717 (upamostat) update:

RHB-107 was included in the U.S. Government-supported PROTECT study, which was a Phase 2 adaptive, randomized, double-blind, placebo-controlled platform trial to evaluate the safety and efficacy of RHB-107 for early outpatient COVID-19 treatment. The study was conducted as part of a master protocol evaluating promising investigational products for safety and efficacy as early outpatient treatment and post-exposure prophylaxis for COVID-19. RHB-107 was the first and only drug to enter the platform and was evaluated in the early treatment arm of the study. The study was planned for a duration of approximately 18 months, but due to challenges to enrollment and U.S. Government funding limitations, enrollment was discontinued after a total of only 92 of the planned 300 participants were enrolled. While a benefit in time to resolution of symptoms and time to viral clearance were observed regarding the efficacy of RHB-107 in this study it did not reach statistical significance. Whether the lack of significant results were due to true lack of efficacy or accrual of fewer than one third of the planned number of patients is unknown.

Purple Biotech Announces New Data from CAPTN-3 Platform Tri-specific IM1240

On April 27, 2026 Purple Biotech Ltd. ("Purple Biotech" or "the Company") (NASDAQ/TASE: PPBT), a clinical-stage company developing a next-generation immunotherapy platform designed to maximize anti-cancer efficacy while minimizing toxicity, reported new preclinical data supporting the clinical potential of IM1240, the Company’s lead CAPTN-3 tri-specific antibody. IM1240 is a conditionally activated, capped-CD3 × 5T4 × NKG2A tri-specific designed to direct tumor-selective T-cell activation while also leveraging NKG2A-mediated checkpoint inhibition to enhance anti-tumor activity.

The new data, generated in the laboratory of Dr. Amir Horowitz of the Tisch Cancer Institute and the Lipschultz Precision Immunology Institute at the Icahn School of Medicine at Mount Sinai, demonstrated potent anti-tumor activity for IM1240 across multiple treatment-resistant patient-derived tumor samples. All seven tested samples responded to IM1240 treatment, including samples from PD-1 or PD-1/chemo-resistant head and neck squamous cell carcinoma metastatic lymph nodes and enfortumab vedotin + PD-1-resistant muscle-invasive bladder cancer.

"These data demonstrate the critical contribution of IM1240’s NKG2A arm, confirmed using a variant with a mutated NKG2A-binding domain, which resulted in loss of apoptotic activity across all samples," said Dr. Horowitz. "Further tissue profiling analyses of NSCLC patient-derived explants demonstrated that treatment with IM1240 induced pronounced immune cell reorganization within the tissue hallmarked by visible induction of mature tertiary lymphoid structures (TLS), which are associated with strong anti-tumor immunity and improved clinical outcomes, as well as increased abundances of CD8 T cells and NK cells, and reduction in numbers of Tregs and tumor cells."

Gil Efron, Chief Executive Officer of Purple Biotech added, "The differentiation of the CAPTN-3 platform from other T cell engagers with the contribution of its NKG2A arm that dually engages NK cells and enhances activity and expands the therapeutic index which we believe is very important for patients’ treatment and for potential improved clinical outcomes, and we are excited by these results from the lab of Dr. Amir Horowitz. IM1240 has the potential to treat resistant patients across multiple tumor types as supported by preclinical data in triple-negative breast cancer, NSCLC, head & neck and bladder cancer models, suggesting a significant market opportunity."

About the CAPTN-3 Platform

CAPTN-3, Purple Biotech’s lead program, is a platform of masked tri-specific antibodies that simultaneously target tumor-associated antigens while engaging both T cells and NK cells. Proprietary capping technology confines immune activation to the tumor microenvironment by masking the CD3-binding arm in circulation and activating it only at the tumor site, significantly expanding the therapeutic window versus unmasked T-cell engagers. The platform’s lead candidates, IM1240 (targeting 5T4) and IM1305 (targeting TROP2), are in preclinical development.

The presentation will include data from the abstract published on the AUA website, as well as updated safety and efficacy data as of an April 5, 2026 data cutoff from 31 enrolled BCG-Naïve patients. A second poster presentation will feature previously reported data from the ADVANCED-2 trial cohort of BCG-Unresponsive patients that was originally presented at the ASCO (Free ASCO Whitepaper) Genitourinary Cancers Symposium in February 2026.

ADVANCED-2 (NCT05951179) is a Phase 2 open-label trial assessing intravesical TARA-002 in NMIBC patients with carcinoma in situ or CIS (± Ta/T1) who are Bacillus Calmette-Guérin (BCG)-Unresponsive or BCG-Naïve. Trial subjects received an induction course, with or without a reinduction, of six weekly intravesical instillations of TARA-002, followed by a maintenance course of three weekly instillations every three months.

About TARA-002

TARA-002 is an investigational cell therapy in development for the treatment of NMIBC and of LMs, for which it has been granted Rare Pediatric Disease, Breakthrough and Fast Track designations by the FDA. TARA-002 is a first-in-class TLR2/NOD2 agonist and novel immunopotentiator derived from inactivated Streptococcus pyogenes with a mechanism of action that includes the activation of innate and adaptive immune pathways within the bladder wall. When TARA-002 is administered, it is hypothesized that innate and adaptive immune cells within the cyst or tumor are activated and produce a pro-inflammatory response with the release of cytokines such as tumor necrosis factor (TNF)-alpha, interferon (IFN)-gamma, IL-6, IL-10 and IL-12. TARA-002 also directly kills tumor cells and triggers a host immune response by inducing immunogenic cell death, which further enhances the antitumor immune response.

TARA-002 was developed from the same master cell bank of genetically distinct group A Streptococcus pyogenes as OK-432, a broad immunopotentiator marketed as Picibanil in Japan by Chugai Pharmaceutical Co., Ltd. Protara has successfully shown manufacturing comparability between TARA-002 and OK-432.

About Non-Muscle Invasive Bladder Cancer (NMIBC)

Bladder cancer is the sixth most common cancer in the United States, with non-muscle invasive bladder cancer (NMIBC) representing approximately 80% of bladder cancer diagnoses, or approximately 65,000 patients in the U.S. each year. NMIBC is cancer found in the tissue that lines the inner surface of the bladder that has not spread into the bladder muscle.
