Recent earnings for Purple Biotech have consistently combined clinical progress with constrained resources. Prior reports highlighted CAPTN-3 advances, including IM1240 and IM1305, alongside cash balances between $5.6M and $10.5M and runway guidance into 2026–2027. Large non-cash items such as a $20.5M impairment and sizable annual net losses were disclosed. Today’s Q1 2026 update continues this theme with a $6.4M cash position, higher operating expenses, and an extended focus on CAPTN-3 as the core development priority.

REHOVOT, Israel, May 15, 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 months ended March 31, 2026 and provided an update on recent business progress.
"We continue to advance the CAPTN-3 platform as a core value driver,” said Gil Efron, Purple Biotech CEO. “New patient-derived tumor data, generated with our collaborators at Mount Sinai, further supports IM1240’s differentiated tri-specific design and its potential to overcome tumor immune evasion and resistance in difficult-to-treat solid tumors. Importantly, the data continues to support the contribution of the NKG2A arm, which enhanced anti-tumor activity across tested samples and improved the therapeutic index. In parallel, our newly formed Scientific Advisory Board and collaboration with Converge Bio provide important scientific and computational expertise as we seek to expand the broader potential of CAPTN-3. Over the remainder of 2026, we plan to build on this momentum by generating additional efficacy evidence across potential indications and advancing new tri-specific antibody combinations.”
Q1 2026 and Recent Clinical & Corporate Highlights:
Generated new patient-derived tumor data supporting IM1240’s differentiated mechanism and anti-tumor activity
- Data generated in the lab 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 demonstrated activity across treatment-resistant samples, including 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.
- Data further supports the contribution of IM1240’s NKG2A arm, which significantly enhanced anti-tumor activity across tested samples and improved the therapeutic index.
- In a patient-derived non-small cell lung cancer (NSCLC) biopsy, IM1240 induced mature tertiary lymphoid structures (TLS) associated with effective anti-tumor immune response and favorable prognosis, corresponding with observed anti-tumor efficacy.
Established Scientific Advisory Board to support CAPTN-3 development
- Formed a CAPTN-3 Scientific Advisory Board (SAB) composed of experts in T-cell engager development, NK and T cell biology, translational science, and clinical oncology.
- The SAB is expected to provide strategic guidance as the company advances IM1240 toward clinical development and continues to evaluate broader development opportunities for the CAPTN-3 platform.
Expanded collaboration with Converge Bio to apply generative AI to tri-specific antibody development
- The collaboration leverages Converge Bio’s proprietary generative AI platform to support the design and optimization of novel tri-specific antibodies for oncology.
- The AI-driven strategy is intended to accelerate discovery timelines, improve candidate quality and developability, and expand CAPTN-3’s potential across additional high-value solid tumor targets and resistance mechanisms.
Advancing IM1240 and IM1305 pre-clinical development toward first-in-human studies in 2027
- IM1240 remains the Company’s lead development priority, with IM1305, targeting TROP2, continuing to support the broader platform opportunity.
- Following the prior announcement that further development of CM24 and NT219 would require partnering or additional investment, the Company has redirected resources toward CAPTN-3 as its core development priority.

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.

The platform’s lead candidate, IM1240, is advancing toward the clinic, and its second candidate, IM1305, is in preclinical development. The Company’s pipeline also includes additional clinical-stage assets, for which further development is pending partnering or investment, including CM24, a CEACAM1-blocking antibody that demonstrated improved outcomes across all efficacy endpoints in a Phase 2 study for the treatment of pancreatic ductal adenocarcinoma, and NT219, a dual IRS1/2 and STAT3 inhibitor in a Phase 2 study for the treatment of recurrent and/or metastatic squamous cell carcinoma of the head and neck. The Company is headquartered in Rehovot, Israel.
