Rhea-AI Filing Summary

Purple Biotech Ltd. reported a much wider full-year 2025 net loss of $26.4 million, driven mainly by a $20.5 million non-cash impairment of its CM24 and NT219 programs as it shifts focus to its CAPTN-3 tri-specific antibody platform.

Adjusted operating loss improved to $6.7 million from $10.4 million in 2024, reflecting lower clinical trial spending, while research and development expenses fell to $3.7 million from $7.6 million. Cash, cash equivalents and deposits totaled about $9.5 million as of December 31, 2025, which the company expects to fund operations into 2027.

The lead CAPTN-3 candidate IM1240 achieved toxicology and manufacturing milestones, and IM1305 was named a development candidate. Separately, CEO Gil Efron will step down in August 2026 for health reasons, remaining on the board and leading corporate development while a search for a new CEO is underway.

Positive

  • Adjusted operating loss improved to $6.7 million for 2025 from $10.4 million in 2024, reflecting reduced clinical trial expenses while CAPTN-3 development continued.
  • Cash and deposits of about $9.5 million as of December 31, 2025 are expected by the company to provide operational runway into 2027.
  • CAPTN-3 platform advanced materially, with IM1240 achieving toxicology and manufacturing milestones and IM1305 named a development candidate, supported by positive preclinical data presented at ESMO Immuno-Oncology Congress 2025.

Negative

  • Non-cash impairment charges of $20.5 million were recorded on CM24 and NT219 after concluding further development depends on partnering or additional financing, effectively sidelining these programs for now.
  • Net loss increased sharply to $26.4 million for 2025 from $7.2 million in 2024, heavily impacting equity, which fell to $9.7 million as of December 31, 2025.
  • CEO Gil Efron will step down as chief executive in August 2026 for health reasons, introducing leadership change risk even though he will remain on the board and lead corporate development.

Insights

Large impairment drives heavy 2025 loss as Purple Biotech pivots to CAPTN-3 with limited cash.

Purple Biotech posted a 2025 operating loss of $27.5 million, mainly due to a $20.5 million impairment on CM24 and NT219 after deciding further work depends on partners or financing. This marks a clear strategic concentration on the CAPTN-3 tri-specific antibody platform.

Excluding non-cash items, non-IFRS adjusted operating loss improved to $6.7 million from $10.4 million in 2024, helped by lower clinical trial costs. However, the full-year net loss rose to $26.4 million, and equity declined to $9.7 million as of December 31, 2025, highlighting balance sheet pressure.

Cash, cash equivalents and short-term deposits of about $9.5 million are expected to provide runway into 2027, while IM1240 and IM1305 advance preclinically. Actual progress will depend on execution of partnering and financing plans described in the risk discussions and forward-looking statements.

CEO transition is planned and gradual, with continuity via board and corporate development role.

CEO Gil Efron will step down in August 2026 for health considerations, after roughly four years in the role and eight years in senior leadership. He will remain on the board and lead corporate development, focusing on partnerships and financing initiatives.

The board has launched a formal search for a new CEO with biotechnology and platform development experience. Because Efron stays in place until a successor is appointed and then shifts to a strategic role, the company describes a smooth and orderly transition aimed at maintaining momentum around the CAPTN-3 platform.

Exhibit 99.1 

 

Purple Biotech Reports Fourth Quarter and Full Year 2025 Financial Results

 

Prioritized development of first tri-specific antibody from the CAPTN-3 platform, IM1240, targeting 5T4 tumor-associated antigen, and second tri-specific antibody, IM1305, named as development candidate, targeting TROP2

 

 Achieved toxicology and manufacturing milestones for IM1240, demonstrating an expanded therapeutic window and commercially viable yield

 

Positive preclinical data presented at ESMO Immuno-Oncology Congress 2025 demonstrates multi-arm anti-tumor activity for both IM1240 and IM1305

 

Total Cash Position of $9.5 million as of December 31, 2025, expected to provide runway into 2027

 

REHOVOT, Israel, March 13, 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 twelve months ended December 31, 2025.

 

“In 2025, we focused on the CAPTN-3 platform and the value it can generate for patients and shareholders, naming a second tri-specific antibody from the platform, IM1305, and strengthening the preclinical data package for the first tri-specific antibody, IM1240. In addition, the capital we raised in 2025 is expected to provide runway into 2027, covering preparations for IM1240 Phase 1 study initiation,” said Gil Efron, Purple Biotech CEO. “During the past year, we made efforts to partner both CM24 and NT219 and, as previously reported, we will not be able to continue developing these assets until we obtain a strategic investment or a partner.”

 

“We are excited by the increasing interest in modalities such as T cell engagers (TCEs) and masked antibodies, both features of the CAPTN-3 tri-specific platform. With a cash position of $9.5 million at the end of 2025, and with data demonstrating that tri-specific antibodies from the CAPTN-3 platform deliver in vivo efficacy, a favorable therapeutic window, and scalable manufacturability, we look forward to sharing additional data and advancing the program over the course of this year,” Gil concluded.

 

Q4 2025 and Recent Clinical & Corporate Highlights:

 

New data on the CAPTN-3 platform were presented at the ESMO Immuno-Oncology Congress 2025, with CAPTN-3’s two lead tri-specific antibodies:

 

Demonstrated significant and sustained tumor regression with two distinct tri-specific antibodies from the CAPTN-3 platform, IM1240 and IM1305, targeting different tumor antigens

 

Transcriptomic analysis across ~11,000 TCGA samples showed that NKG2A expression is strongly associated with tumor expression of 5T4 or TROP2, supporting the inclusion of the NKG2A arm in CAPTN-3 designs

 

NKG2A arm significantly contributes to IM1240 anti-cancer immune activity in PD1-resistant patient-derived explants

 

Toxicology study demonstrated an expanded therapeutic window for IM1240 (capped-CD3x5T4xNKG2A)

 

IM1240 demonstrated improved tolerability in a toxicology study at doses up to 300-fold higher than a non-capped comparator, with significantly reduced immune-related toxicity, including minimal cytokine release. These results highlight the unique safety profile of this approach, which may address a key limitation of certain current T-cell engagers, where cytokine release syndrome can restrict dosing

 

IM1240’s pharmacokinetic profile showed increased systemic exposure and a prolonged circulating half-life, enabled by its human serum albumin moiety and capping design

 

 

 

 

Achieved manufacturing milestone for IM1240

 

Achieved commercially viable yield for IM1240, positioning the program competitively for anticipated future development

 

Validates the potential scalability of the CAPTN-3 tri-specific antibody platform

 

Financial Results for the Three Months Ended December 31, 2025

 

Research and Development Expenses were $1.8 million, an increase of $1.4 million, compared to $0.5 million in the same period of 2024, primarily due to CAPTN-3 platform CMC (chemistry, manufacturing, and controls) development activities.

 

General and Administrative Expenses were $1.1 million, compared to $0.6 million in the same period of 2024, an increase of $0.6 million, primarily attributable to increased professional services fees and higher cash and non-cash compensation expenses.

 

Impairment Loss Expenses were $20.5 million for the period, in connection with the impairment of in-process research and development assets related to CM24 and NT219 as of December 31, 2025. Following the Company’s determination that the continued development of CM24 and NT219 is contingent upon partnering or the availability of additional financing under the circumstances, and in light of the Company’s focus of its development efforts on CAPTN-3, the Company determined that the recoverable value of the CM24 and NT219 assets was less than their carrying value, resulting in the recognition of $20.5 million of impairment charges related to these programs.

 

Operating Loss was $23.4 million, an increase of $22.4 million, compared to $1.0 million in the same period of 2024, primarily reflecting the $20.5 million non-cash impairment expenses recognized during the period.

 

Adjusted Operating Loss (as reconciled below) was $2.9 million, compared to $1.0 million in the same period of 2024 primarily reflecting the increase in CAPTN-3 platform development activities.

 

Financial Expenses, Net, were $0.2 million, compared to financial income of $0.6 million in the same period of 2024, primarily due to fair value adjustments of warrants and foreign exchange rate fluctuations.

 

Net Loss was $23.6 million, an increase of $23.1 million, compared to $0.4 million in the same period of 2024, primarily reflecting the $20.5 million non-cash impairment expenses recognized during the period.

 

As of December 31, 2025, Purple Biotech had cash and cash equivalents and short-term deposits of $9.5 million, which is expected to provide the Company with a cash runway into 2027.

 

Financial Results for the Twelve Months Ended December 31, 2025

 

Research and Development Expenses were $3.7 million, a decrease of $3.9 million, compared to $7.6 million in the same period of 2024. The decrease was primarily due to lower clinical trial expenses, partially offset by CMC development activities related to the CAPTN-3 platform.

 

General and Administrative Expenses were $3.2 million, consistent with the same period of 2024.

 

Impairment Loss Expenses were $20.5 million for the year ended December 31, 2025.  The Company determined that the recoverable value of the CM24 and NT219 assets was less than their carrying value as of December 31, 2025, resulting in the recognition of $20.5 million of impairment charges related to these programs.  No impairment loss expenses were recognized in 2024.

 

2

 

 

Operating Loss was $27.5 million, an increase of $16.5 million, compared to $11 million in the same period of 2024, primarily reflecting the $20.5 million non-cash impairment expenses recognized during the period, partially offset by lower clinical trial expenses.

 

Adjusted Operating Loss (as reconciled below) was $6.7 million, compared to $10.4 million in the same period of 2024 primarily reflecting the decrease in clinical trial expenses.

 

Net Loss for the year ended December 31, 2025 was $26.4 million, or $54.9 loss per basic ADS, compared to a net loss of $7.2 million, or $44.4 loss per basic and diluted ADS, in the same period of 2024. The increase in net loss was primarily due to the $20.5 million non-cash impairment expenses recognized during the period.

 

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. This non-IFRS measure is not based on any standardized methodology prescribed by IFRS and is not necessarily comparable to similar measures presented by other companies. Adjusted operating loss adjusts for non-cash share-based compensation expenses and non-cash impairment expenses. The Company’s management and board of directors utilize this non-IFRS financial measure to evaluate the Company’s performance. The Company provides this non-IFRS measure of the Company’s performance to investors because management believes that this non-IFRS financial measure, when viewed with the Company’s results under IFRS and the accompanying reconciliations, are useful in identifying underlying trends in ongoing operations. However, this non-IFRS measure is not a measure of financial performance under IFRS and, accordingly, should not be considered as an alternative to IFRS measures as indicators of operating performance. Further, this non-IFRS measure should not be considered a measure 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.

Purple Biotech Announces CEO Transition

 

Gil Efron to Step Down as CEO in August 2026 for Health Considerations; Will Continue to Lead Corporate Development

 

REHOVOT, Israel, March 13, 2026 (GLOBE NEWSWIRE) -- Purple Biotech Ltd. (NASDAQ/TASE: PPBT), a clinical-stage company developing next-generation cancer therapies, today announced that Gil Efron, Chief Executive Officer, will step down from his role as CEO effective August 2026.

 

Mr. Efron will remain actively involved with the Company, transitioning to lead corporate development and continuing as a member of the Board of Directors. In this new capacity, he will focus on identifying strategic initiatives, partnerships, and support the Company’s financing activities as needed. The Board of Directors has initiated a formal search process to appoint a new Chief Executive Officer.

 

Mr. Efron has served in senior leadership roles at Purple Biotech for the past eight years, including as Chief Financial Officer and, since 2022, as Chief Executive Officer. During his tenure, he led the Company through a period of significant transformation and strategic repositioning, including advancing the Company’s focus on the promising CAPTN-3 tri-specific antibody platform.

 

Eric Rowinsky, MD, Chairman of Purple Biotech’s Board of Directors, stated:

 

“On behalf of the Board of Directors, I would like to sincerely thank Gil for his dedication and exceptional leadership. Gil played a critical role in repositioning Purple Biotech’s activities around the highly promising CAPTN-3 platform and strengthening the Company’s strategic direction. Importantly, Gil will remain closely involved with Purple Biotech as a member of the Board and in corporate development, and we look forward to continuing to benefit from his experience and vision as we move forward. The Board remains confident in the strength of the Company’s pipeline, its commitment to innovation and its world-class employees.”

 

Gil Efron, Chief Executive Officer of Purple Biotech, commented:

 

“Serving Purple Biotech over the past eight years, first as CFO and later as CEO, has been a privilege. Together with a dedicated team, we have navigated a complex environment and positioned the Company around a very exciting scientific and business opportunity. I firmly believe in the potential of our lead asset and the CAPTN-3 platform, as well as in the broader era of emerging technologies that Purple Biotech is well positioned to embrace and lead. Due to health considerations, I believe this is the right time for me to transition from the CEO role, but I remain deeply committed to the Company, its strong team and its future. I look forward to continuing to support Purple Biotech through corporate development initiatives, building strategic partnerships, and helping secure the resources needed to advance our programs.”

 

The Board of Directors has initiated a search process to identify a new Chief Executive Officer with experience leading innovative biotechnology companies and advancing novel therapeutic platforms. Mr. Efron will continue to serve as CEO until August 2026 or until a successor is appointed, ensuring a smooth and orderly leadership transition. Mr. Efron has also been appointed to the Board of Directors, to serve as a second class director, effective immediately and until the annual general meeting of shareholders of the Company to be held in 2026.

 

About the CAPTN-3 Platform

 

CAPTN-3, Purple Biotech's lead program, is a platform of capped 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 conventional T-cell engagers. The platform’s lead candidates, IM1240 (targeting 5T4) and IM1305 (targeting TROP2), are in preclinical development.
