New preclinical data presented at European Association for Cancer Research (EACR) 2026 Annual Congress, which further validates the differentiated profile of IM1240's anti-tumor activity, favorable safety and pharmacokinetic profile, and broad therapeutic window

IM1240 tri-specific antibody (capped-CD3x5T4xNKG2A) is aimed at entering clinical studies in 2027

Total Cash Position of $6.1 million as of June 30, 2026, provides a runway through mid-2027 based on current management estimates

REHOVOT, Israel, Aug. 07, 2026 (GLOBE NEWSWIRE) -- 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 potency while minimizing toxicity, today announced financial results for the three and six months ended June 30, 2026, and provided an update on recent business progress, including new data supporting the differentiation and partnering potential of our CAPTN-3 platform.

"We are encouraged by the interest in our differentiated CAPTN-3 T-cell engager platform. The consistent preclinical data generated to date continue to strengthen the platform's differentiated profile, demonstrating an expanded therapeutic window enabled by both enhanced anti-tumor activity through NKG2A engagement and our CD3 capping technology. These findings further support IM1240 as a compelling candidate as we advance toward the clinic. Our total cash position of approximately $6.1 million as of June 30, 2026, is expected to provide a cash runway through mid-2027 based on current management estimates. We continue to pursue a strategic collaboration to support the clinical advancement of IM1240 while preserving shareholder value, and to evaluate financing alternatives to support the planned Phase 1 study."

Recent Clinical & Corporate Highlights:

Presented new preclinical data at EACR 2026 supporting IM1240’s safety, pharmacokinetic profile and broad therapeutic window

A non-GLP toxicology study in non-human primates validates the CAPTN-3 masking strategy and supports the planned advancement of IM1240 toward a first-in-human clinical study in 2027.
IM1240 demonstrated an approximately 8-fold longer half-life and 16-fold greater systemic exposure compared to the non-capped variant, together with dose-proportional pharmacokinetics and a broad therapeutic window.
The CAPTN-3 masking strategy mitigated peripheral T-cell activation and systemic cytokine release. IM1240 induced minimal IL-6 and TNF-α at a dose of 10 mg/kg, whereas the non-capped variant induced robust cytokine release at a dose of 0.03 mg/kg.

Generated new patient-derived tumor data supporting IM1240’s differentiated mechanism and anti-tumor activity

Data generated in collaboration with the laboratory of Amir Horowitz, PhD, at the Tisch Cancer Institute at the Icahn School of Medicine at Mount Sinai, demonstrated that all tested patient-derived tumor samples responded to IM1240 treatment.

IM1240 induced apoptosis of PD-1-resistant patient-derived biopsies from six head and neck squamous cell carcinoma (HNSCC) metastatic lymph node samples and one enfortumab vedotin/pembrolizumab-resistant muscle-invasive bladder cancer sample, with both the CD3 and NKG2A functional arms required for full activity.
In a PD-1/chemotherapy-resistant non-small cell lung cancer (NSCLC) patient-derived explant, IM1240 induced mature tertiary lymphoid structures (TLS) - immune cell organizations associated with effective anti-tumor immunity and favorable clinical prognosis - while increasing CD8 T-cell and NK-cell abundance and reducing regulatory T cells (Tregs) and tumor cells. These effects were not observed with IM1340, the NKG2A loss-of-function variant, underscoring the essential and differentiated contribution of the NKG2A arm.

Financial Results for the Three Months Ended June 30, 2026

Research and Development Expenses were $0.7 million for the three months ended June 30, 2026, as compared to $0.6 million for the corresponding period in 2025, representing an increase of $0.1 million. The increase is primarily attributable to the advancement of the IM1240 development program, partially offset by a decrease in clinical expenses associated with the CM24 and NT219 programs.

General and Administrative Expenses were $0.6 million for the three months ended June 30, 2026, as compared to $0.7 million for the corresponding period in 2025, representing a decrease of $0.1 million, primarily due to lower regulatory and professional services expenses.

Operating Loss was $1.3 million for the three months ended June 30, 2026, representing an increase of $0.1 million as compared to $1.2 million for the corresponding period in 2025.

Adjusted Operating Loss (as reconciled below) was $1.2 million for the three months ended June 30, 2026, as compared to $1.2 million for the corresponding period in 2025.

Financial Income, Net was $1.7 million for the three months ended June 30, 2026, as compared to $0.1 million for the corresponding period in 2025. The increase is primarily attributable to a higher non-cash gain arising from the revaluation of outstanding warrants.

Net Income was $0.4 million for the three months ended June 30, 2026, as compared to a net loss of $1.1 million for the corresponding period in 2025. The change was primarily driven by increased finance income resulting from changes in the fair value of outstanding warrants.

Adjusted Net Loss (as reconciled below) was $1.2 million for the three months ended June 30, 2026, as compared to $1.1 million for the corresponding period in 2025. Adjusted net loss excludes non-cash share-based compensation expenses and finance income resulting from changes in the fair value of outstanding warrants.

As of June 30, 2026, Purple Biotech had cash and cash equivalents and short-term deposits of $6.1 million, which, based on current management estimates, are expected to provide the Company with a cash runway through mid-2027.

Non-IFRS Financial Measures

This press release includes information about certain financial measures that are not prepared in accordance with International Financial Reporting Standards ("IFRS"), including adjusted operating loss and adjusted net loss. These non-IFRS measures are not based on any standardized methodology prescribed by IFRS and are not necessarily comparable to similar measures presented by other companies. Adjusted operating loss and adjusted net loss adjust for non-cash share-based compensation expenses, and adjusted net loss also adjusts for finance income from financial instruments. The Company's management and board of directors utilize these non-IFRS financial measures to evaluate the Company's performance. The Company provides these non-IFRS measures of the Company's performance to investors because management believes that these non-IFRS financial measures, when viewed with the Company's results under IFRS and the accompanying reconciliations, are useful in identifying underlying trends in ongoing operations. However, these non-IFRS measures are not measures of financial performance under IFRS and, accordingly, should not be considered in isolation or as alternatives to IFRS measures as indicators of operating performance. Further, these non-IFRS measures should not be considered measures of the Company's liquidity. A reconciliation of certain IFRS to non-IFRS financial measures has been provided in the tables included in this press release.
