PDS Biotech Reports Second Quarter 2026 Financial Results

PRINCETON, N.J., August 13, 2026 -- PDS Biotechnology Corporation (Nasdaq: PDSB) (“PDS Biotech” or the “Company”), a clinical-stage biotechnology company focused on developing targeted immunotherapies for cancer, today provided a business and clinical programs update and reported financial results for the quarter ended June 30, 2026.

Clinical and Corporate Update

•

Announced publication of positive clinical and immunological biomarker data from Stage 1 of the NCI-led metastatic colorectal cancer (mCRC) Phase 2, open-label, single-center, non-randomized clinical trial evaluating PDS0301 (formerly PDS01ADC), the Company’s tumor-targeted IL-12 immunocytokine. The clinical trial results, published in the March 2026 issue of the Journal of Clinical Oncology (JCO) Oncology Advances, included:

o

Objective response rate (ORR) by RECIST v1.1: 77.8% (7/9) at six months; in the parallel trial without PDS0301, the ORR was 35% (7/20)

o

24-month survival rate approximately 80%; in the parallel trial without PDS0301, the 24-month survival rate was approximately 35%

o

Extrahepatic progression-free survival (PFS): median not reached at minimum follow-up of 13.1 months; in the parallel trial without PDS0301, the PFS was 8.1 months

On August 11, 2026, the Company issued a shareholder letter outlining its strategic refocus to prioritize PDS0301, its tumor-targeted IL-12 immunocytokine, as its lead development program. As part of this strategy, the Company will cease further internal investment in PDS0101, including the discontinuation of the VERSATILE-003 Phase 3 trial, and intends to pursue strategic partnerships or other externally funded opportunities for the continued development of PDS0101. The Company believes that concentrating its capital and development resources on PDS0301, while maintaining financial discipline and preserving the potential value of PDS0101 through partnerships, may provide the strongest path toward creating long-term value for patients and shareholders.

Second Quarter 2026 Financial Results

Reported net loss was $9.8 million, or $0.18 per basic and diluted share, for the three months ended June 30, 2026, compared to $9.4 million, or $0.21 per basic and diluted share, for the three months ended June 30, 2025.

Research and development expenses were $3.3 million for the three months ended June 30, 2026, compared to $4.2 million for the three months ended June 30, 2025. The decrease was primarily attributable to lower clinical trial costs, manufacturing costs and personnel costs, partially offset by higher stock-based compensation expense.

General and administrative expenses were $3.2 million for the three months ended June 30, 2026, compared to $3.4 million for the three months ended June 30, 2025. The decrease was primarily attributable to a decrease in professional fees.

Total operating expenses were $6.5 million for the three months ended June 30, 2026, compared to $7.6 million for the three months ended June 30, 2025.

Net interest expenses were $3.3 million for the three months ended June 30, 2026, compared to $1.8 million for the three months ended June 30, 2025. The increase was primarily due to a non-cash charge for loss on retirement of debt, partially offset by lower cash interest payments.

The Company’s cash balance as of June 30, 2026, was $5.6 million.

PDS Biotech Reports First Quarter 2026 Financial Results and Provides Clinical Programs and Corporate Update

Investor Webcast Scheduled for 8:00 am ET

PRINCETON, N.J., May 13, 2026 -- PDS Biotechnology Corporation (Nasdaq: PDSB) (“PDS Biotech” or the “Company”), a late-stage immunotherapy company focused on transforming how the immune system targets and kills cancers, today provided a business and clinical programs update and reported financial results for the quarter ended March 31, 2026.

“During the first quarter, we made meaningful clinical and regulatory progress across our clinical pipeline,” said Frank Bedu-Addo, PhD, President and CEO of PDS Biotech. “We work towards restarting enrollment in the amended VERSATILE-003 Phase 3 trial. With regards to PDS01ADC, we have completed enrollment in the metastatic colorectal cancer trial, and the advanced castration resistant prostate cancer trial continues to recruit well”.

Dr. Bedu-Addo continued: “We believe the progress achieved during the quarter reflects the continued advancement and maturation of our clinical portfolio. We remain focused on advancing potentially differentiated immunotherapy candidates designed to address significant unmet medical needs for patients with difficult-to-treat cancers”.

Clinical and Corporate Update

•

Amended VERSATILE-003 Phase 3 clinical trial protocol to

incorporate progression-free survival (PFS) as an interim primary endpoint, creating a potential accelerated approval pathway for PDS0101 in HPV16-positive recurrent and/or metastatic head and neck cancer. Median overall survival remains the primary endpoint for full FDA approval. The amendment also reduces the number of enrolled patients while maintaining statistical power. Patients already enrolled prior to the amendment remain on the trial and continue to receive treatment.

•

Announced publication of positive clinical and immunological biomarker data from Stage 1 of NCI-led Metastatic Colorectal Cancer (mCRC) trial evaluating PDS01ADC, the Company’s tumor-targeted IL-12 immunocytokine. The results, published in the March issue of Journal of Clinical Oncology (JCO) Oncology Advances, included:

o

Objective response rate (ORR) by RECIST v1.1: 77.8% (7/9) at six months; in the parallel trial without PDS01ADC, the ORR was 35% (7/20)

o

24-month survival rate approximately 85%; in the parallel trial without PDS01ADC, the 24-month survival rate was approximately 40%

o

Extrahepatic progression-free survival (PFS): median not reached at minimum follow-up of 13.1 months; in the parallel trial without PDS01ADC, the PFS was 8.1 months

•

Presented encouraging early results from an NCI-led trial investigating PDS01ADC at the AACR special conference on prostate cancer research. In patients with metastatic castration-resistant prostate cancer (mCRPC) the majority of whom received third-line treatment options — the combination of PDS01ADC and docetaxel demonstrated encouraging median PFS of 9.6 months and a median PSA decline of 40%, with 6 of 16 patients achieving greater than 50% decline.

•

Strengthened the intellectual property estate for PDS0101 with new patents granted in the U.S. and Japan. The new U.S. patent, combined with anticipated biologics exclusivity, extends market protection into the 2040s. The Japanese patent adds broad composition of matter claims to existing protections across major markets.

First Quarter 2026 Financial Results

Reported net loss for the quarter ended March 31, 2026, was approximately $7.3 million, or $0.13 per basic and diluted share, compared to a net loss of $8.5 million, or $0.21 per basic and diluted share for the quarter ended March 31, 2025.

Research and development expenses for the quarter ended March 31, 2026, were $3.5 million, compared to $5.8 million for the quarter ended March 31, 2025. The decrease was primarily due to lower clinical and manufacturing costs.

PDS Biotech Reports Full Year 2025 Financial Results and Provides Update on PDS0101 Phase 3 Program and PDS01ADC Clinical Advancement

Filed Phase 3 Amendment Incorporates PFS as Interim Primary Endpoint Expected to Shorten Trial Duration and Reduce Costs

Conference Call and Webcast Today at 8:00 am Eastern Time

PRINCETON, N.J., March 30, 2026 -- PDS Biotechnology Corporation (Nasdaq: PDSB) (“PDS Biotech” or the “Company”), a late-stage immunotherapy company focused on transforming how the immune system targets and kills cancers, today provided a business and clinical programs update and reported financial results for the quarter and year ended December 31, 2025.

"The fourth quarter capped a year of important progress for PDS Biotech, marked by meaningful advances across our clinical programs, financial discipline, and intellectual property portfolio," said Frank Bedu-Addo, PhD, President and CEO of PDS Biotech. "Building on the compelling topline data from our VERSATILE-002 Phase 2 trial, we believe the VERSATILE-003 protocol amendment has the potential to create a more efficient path to accelerated approval — shortening the trial's duration, reducing costs, and accelerating our timeline to regulatory submission — while preserving overall survival as the basis for full approval. For patients living with HPV16-positive head and neck cancer, a disease with significant and growing unmet need, we believe PDS0101 represents a promising treatment option, and we remain focused on advancing it as efficiently as possible."

Dr. Bedu-Addo added: “Combined with early data from one of our PDS01ADC Phase 2 programs and expanded patent protections for the Versamune® platform extending into the 2040s, we believe we have meaningful opportunities ahead as we continue to execute against our priorities in 2026."
