"The first six months of 2026 were highlighted by steady and strong execution across our organization," stated Kris Vaddi, Ph.D., Chief Executive Officer of Prelude. "We’ve made considerable progress advancing our three core programs. Notably, we are well positioned to initiate, in the fourth quarter, the first clinical trial of our highly differentiated, selective KAT6A degrader, PRT13722 in HR+ breast cancer. Enrollment in our phase 1 study of PRT12396, our mutant-selective JAK2V617F inhibitor, continues, and we are also making excellent progress toward advancing the lead development candidates from our mCALR degrader antibody conjugate program."

Program Updates and Upcoming Milestones

Highly selective KAT6A oral degrader program

KAT6 is an emerging and recently validated target in the treatment of HR+ breast cancer. Prelude discovered and is developing first-in-class, highly potent, highly selective and orally bioavailable KAT6A selective degraders. Pending clearance of the IND application, the Company expects the phase 1 study initiation of PRT13722 in HR+ breast cancer in the fourth quarter of 2026. Prelude believes that selectively degrading KAT6A has the potential for improved efficacy, tolerability and combinability with other agents relative to non-selective inhibitors of KAT6A/B.

The Company presented preclinical data supporting this hypothesis at the AACR (Free AACR Whitepaper) Annual Meeting 2026. The presentation can be found at Publications – Prelude Therapeutics.

Mutant selective JAK2V617F JH2 inhibitor program

JAK2V617F is the primary driver mutation responsible for disease progression in the majority of patients living with myeloproliferative neoplasms (MPNs). The mutation impacts approximately 95% of patients with polycythemia vera (PV), 60% of patients with essential thrombocythemia (ET) and 55% of patients with myelofibrosis (MF). Identifying JAK2 JH2 inhibitors that selectively target V617F+ cells has long been the goal for advancing the treatment of MPNs. Prelude has designed and identified novel allosteric inhibitors that bind into the JAK2 JH2 "deep pocket" where the V617F mutation resides. These candidates demonstrate mutant specific inhibition in multiple preclinical models of MPNs. Prelude believes this approach may have the potential to reduce mutant allele burden, slow or even reverse disease progression, and transform treatment outcomes for MPN patients.

PRT12396, Prelude’s lead, mutant-selective JAK2V617F inhibitor, received IND clearance from the U.S. Food and Drug Administration, as previously announced in February 2026 and is currently enrolling patients into a Phase 1 study of PRT12396 in patients with PV and MF. The Company also continues to make progress advancing next generation development candidates with potential best-in-class selectivity profiles.

The JAK2V617F inhibitor program is subject to an exclusive option agreement with Incyte announced in November 2025.

Mutated calreticulin (mCALR) DAC discovery program

Mutant CALR is a neoantigen presented on the cell surface of malignant myeloid cells but not normal cells and is found in approximately 25-35% of patients with MF and essential thrombocythemia (ET). Recently, a mCALR-targeted monoclonal antibody demonstrated robust clinical activity in high-risk ET patients. Prelude is advancing mCALR-targeted degrader antibody conjugates (DACs) using the Company’s proprietary degrader payloads as a differentiated approach for patients with CALR mutations. This discovery program is wholly owned and controlled by Prelude.

The Company presented the preclinical data from the program at the European Hematology Association (EHA) (Free EHA Whitepaper) 2025 Congress in June and the American Society of Hematology (ASH) (Free ASH Whitepaper) 67th Annual Meeting in December 2025. The presentations can be found at Publications – Prelude Therapeutics.

Degrader payloads for next generation DACs

Prelude is leveraging our expertise in targeted protein degradation to discover and develop novel degrader payloads for use with next generation DACs. We have developed highly potent SMARCA2/4 and CDK9 degrader payloads optimized for efficacy, tolerability and developability when coupled to a wide range of different antibodies. Building on our existing DAC partnership with AbCellera, the Company’s payloads and corresponding payload-linkers are available for licensing to additional partners to expand the reach of this new technology.

We have recently published preclinical data demonstrating that next generation DACs using Prelude degrader payloads have potential for significantly better in vivo efficacy and tolerability compared to traditional cytotoxic ADCs when tested head-to-head in xenograft models. These data can be found at: Publications – Prelude Therapeutics

Corporate Updates

In April 2026, the Company announced the appointment of Charles Morris, M.D. as Chief Medical Officer.

Second Quarter 2026 Financial Results 

Cash, Cash Equivalents, Restricted cash and Marketable securities:

Cash, cash equivalents, restricted cash and marketable securities as of June 30, 2026 were $155.2 million. The Company anticipates that its existing cash, cash equivalents, restricted cash and marketable securities will fund Prelude’s operations into the second quarter of 2028.

Research and Development (R&D) Expenses:

For the three months ended June 30, 2026, R&D expense decreased to $16.1 from $25.8 million for the prior year period. Included in the R&D expense for the three months ended June 30, 2026 was $1.0 million of non-cash expense related to stock-based compensation expense, including employee stock options, compared to $2.2 million for the three months ended June 30, 2025. Along with the decrease in stock-based compensation expense, the decrease was primarily related to lower expense incurred for our SMARCA2 clinical trials which we paused in 2025 along with a decrease in employee related expenses due to a workforce reduction in the second half of 2025. Research and development expenses may fluctuate from period to period depending upon the stage of certain projects and the level of preclinical and clinical trial-related activities.

Pliant Therapeutics Provides Corporate Update and Reports Second Quarter 2026 Financial Results

On August 11, 2026 Pliant Therapeutics, Inc. (Nasdaq: PLRX), a clinical-stage biotechnology company focused on the discovery and development of integrin-based therapeutics, reported a corporate update and announced second quarter 2026 financial results.

"In the second quarter, we continued to execute across the portfolio, led by strong enrollment in FORTIFY," said Bernard Coulie, M.D., Ph.D., President and Chief Executive Officer of Pliant. "With the appointments of Flavia and Robert to the board, Pliant now has deep global oncology drug development and commercialization expertise at this important time for our oncology program. We continue to make progress on our proprietary integrin-targeted drug-delivery platform and look forward to sharing more information on the platform soon."
Oncology Program
PLN-101095 is an oral, small molecule, dual selective inhibitor of αvβ8 and αvβ1 integrins designed to overcome checkpoint resistance by blocking TGF-β activation in the tumor microenvironment. Pliant is currently conducting FORTIFY, a Phase 1a/1b open-label, dose-escalation and indication expansion trial (NCT0670706), to evaluate the safety, tolerability, pharmacokinetics, and preliminary evidence of antitumor activity of PLN-101095, in combination with pembrolizumab, in patients with immune checkpoint inhibitor (ICI)-refractory advanced or metastatic solid tumors.

•Enrollment continues in FORTIFY, a Phase 1b indication expansion trial. FORTIFY will enroll up to 102 patients across three cohorts including non-small cell lung cancer (NSCLC), clear cell renal cell carcinoma (ccRCC) and tumors with high tumor mutational burden. Patients are treated for 14 days with PLN-101095 dosed at 1,000 mg twice daily as monotherapy, after which pembrolizumab is added as combination therapy. Enrollment remains strong, progressing ahead of schedule. Interim data is expected in 2027.

•Oral presentation at AACR (Free AACR Whitepaper) of updated PLN-101095 Phase 1 data highlights monotherapy biomarker data showing a coordinated T-cell reactivation cascade in responders. In July, at the American Association for Cancer Research (AACR) (Free AACR Whitepaper)’s (AACR) (Free AACR Whitepaper) Drug Discovery and Development conference, the Company reviewed encouraging PLN-101095 Phase 1 monotherapy biomarker data. As previously reported, all responding patients showed large increases in plasma interferon gamma (IFN-γ), a modulator of anti-tumor immunity, after 14 days of monotherapy with PLN-101095. Updated data show that blocking of αvβ8 by PLN-101095 also resulted in increases in CXCL9, a recruiter of T cells, and granzyme-B, a marker for cytotoxic arming in responding patients. Increased IFN-γ, CXCL9 and granzyme-B after PLN-101095 monotherapy signals a shift in the tumor microenvironment that could potentially resensitize tumors to pembrolizumab. Importantly, no non-responders experienced increases in these biomarkers.

Integrin-Targeted Delivery Platform

•Utilizing cell-specific integrin receptors, Pliant has developed a platform to deliver drug payloads, including siRNAs, to selective tissue types. Current programs are focused on delivering siRNAs to skeletal muscle cells and other tissues. Preclinical proof-of-concept studies are currently ongoing. The Company believes this integrin-targeting drug-delivery platform has the potential for broad applicability across multiple disease areas utilizing a variety of drug payloads. Pliant plans to provide additional detail on the platform and path forward, including initial treatment indications, in the second half of 2026.

Corporate Highlights
•Appointed Flavia Borellini, Ph.D. and Robert Iannone, M.D., M.S.C.E. to the Company’s Board of Directors. Dr. Borellini brings more than 25 years of executive management experience in the biopharmaceutical industry with a focus on the global development of targeted oncology drugs from preclinical to commercial stage. Dr. Iannone, who currently serves as Executive Vice President, Research and Development and Chief Medical Officer at Jazz Pharmaceuticals, brings more than two decades of executive drug development and regulatory leadership, including the approval of several targeted and immuno-oncology medicines.

Second Quarter 2026 Financial Results
•Research and development expenses were $16.7 million, as compared to $32.2 million for the prior-year quarter. The decrease was primarily due to completing close-out activities for BEACON-IPF, a Phase 2b/3 study of bexotegrast, in 2025 and reduced personnel-related expenses, including stock based compensation, driven by decreased headcount compared to prior year.
•General and administrative expenses were $7.1 million, as compared to $13.4 million for the prior-year quarter. The decrease was primarily due to personnel-related expenses, including stock-based compensation, driven by decreased headcount compared to prior year.
•Net loss was $22.4 million as compared to $43.3 million for the prior-year quarter. The decrease was primarily due to significantly lower operating expenses following the termination of bexotegrast development in IPF in 2025 and decreased personnel-related expenses, including stock-based compensation, driven by reduced headcount compared to prior year.
•As of June 30, 2026, the Company had cash, cash equivalents and short-term investments of $159.6 million which the Company expects to be sufficient to fund operations into the second half of 2028.

PDS Biotech Announces Strategic Refocus Prioritizing PDS0301 in Metastatic Colorectal Cancer (mCRC) and Partnership Strategy for PDS0101

On August 11, 2026 PDS Biotechnology Corporation (Nasdaq: PDSB) ("PDS Biotech" or the "Company"), a late-stage immunotherapy company focused on developing targeted immunotherapies for cancer, reported a Letter to Shareholders from Frank Bedu-Addo, Ph.D., Chief Executive Officer and Director of PDS Biotech:

"Dear Fellow Shareholders,

Over the past several months, our Board of Directors and management team conducted a comprehensive review of our development portfolio, capital allocation priorities and long-term strategy. Following this review, we believe the best path to creating long-term shareholder value is to prioritize the advancement of PDS0301, our tumor-targeted immunocytokine, while pursuing strategic partnership opportunities for PDS0101.

The oncology treatment landscape is rapidly evolving with the emergence of various precision medicines. Despite these advances, treatment resistance and limited durability of response remain significant challenges for many patients with advanced solid tumors. Based on supportive preclinical and clinical data, we believe PDS0301 has the potential to address these challenges by precisely targeting and remodeling the tumor microenvironment, potentially enhancing the effectiveness and durability of current and emerging oncology therapies. To address this medical need, we have designed PDS0301 for use, in combination with other oncology therapies, to remodel the tumor microenvironment to potentially promote more effective anti-tumor responses in patients. We believe the remodeling of the tumor microenvironment is an important factor in addressing treatment resistance and reversing disease progression. Further, this mechanism could enable PDS0301 to complement a broad range of current and emerging oncology therapies, including RAS pathway inhibitors, bispecific antibodies, ADCs and radioligand therapies.

We concluded that our resources should be redirected toward PDS0301, where we believe the combination of encouraging clinical data, development opportunity and capital requirements provide a potentially more attractive path to long-term shareholder value.

Phase 2 mCRC Results

Patients with metastatic microsatellite stable (MSS) and mismatch repair-proficient (pMMR) colorectal cancer, particularly those with liver metastases, continue to face substantial unmet medical needs, and median overall survival is reported to be less than 10 months and objective response rates (ORR) less than 25%1. Clinical data generated in collaboration with the National Cancer Institute demonstrated encouraging and durable activity, including a 71% ORR at 6 months and an 80% 24-month survival rate in patients with metastatic MSS and pMMR colorectal cancer and liver metastases2. Together with safety observed in more than 380 treated patients, these findings strengthen our conviction that PDS0301 has the potential to address one of the more significant limitations of current oncology therapies.

Strategic Partnering Opportunities for PDS0101

We have decided that we will cease further internal investment in the PDS0101 Phase 3 VERSATILE-003 trial, including the discontinuation of the VERSATILE-003 Phase 3 trial, and intend to pursue strategic partnerships or other externally funded opportunities for the continued development of PDS0101. This decision follows a comprehensive assessment of the capital, time and resources required to complete the Phase 3 trial and support commercialization of PDS0101. This decision reflects our commitment to disciplined capital allocation rather than a change in our view of the underlying PDS0101 science and clinical data. We believe the strength of the Phase 2 clinical results allows us to preserve the potential value of PDS0101 through a strategic partnership.

Why We Believe PDS0301 Represents Our Greatest Opportunity

Our objective is to establish PDS0301 as a foundational component of next-generation oncology therapies for multiple difficult-to-treat solid tumors.

We believe PDS0301 offers several important differentiators:

•
Encouraging efficacy as a single agent (monotherapy) in advanced, recurrent cancer.

•
Encouraging efficacy with chemotherapy in difficult-to-treat metastatic colorectal cancer.

•
More than 380 patients treated with an encouraging safety and tolerability profile.

•
A mechanism designed to remodel the tumor microenvironment and to reshape the anti-tumor immune response in patients, leading to more effective and more durable or long-lasting therapy. The mechanism also has the potential to improve the durability of ADCs, bispecific antibodies, radioligands, targeted therapies and immunotherapies.

•
Clinical activity and tolerability observed across multiple difficult-to-treat solid tumors as a single agent and in double and triple combinations.

•
A Phase 2b development strategy designed to take into account feedback from the FDA.

Although metastatic colorectal cancer is our lead development program, our maturing clinical data in various solid tumors suggests that PDS0301 may have broader application. By targeting the tumor microenvironment rather than a single oncogenic pathway, PDS0301 appears to have applicability across multiple difficult-to-treat solid tumors which could result in several combination oncology therapy strategies.

Beyond colorectal cancer, PDS0301 is also being evaluated in recurrent prostate cancer, metastatic castration resistant prostate cancer, Kaposi sarcoma, HPV16-positive cancers, and other National Cancer Institute-sponsored clinical trials, providing additional opportunities to demonstrate the breadth of PDS0301.

Looking Ahead

A randomized Phase 2b trial with PDS0301 has been designed taking into account feedback received from the FDA and is intended to generate meaningful clinical data with disciplined capital investment.

Over the next 18 to 24 months, we expect to:

•
Advance PDS0301 through a randomized Phase 2b development program.
•
Identify and assess strategic partnering opportunities for PDS0101.

•
Maintain disciplined capital allocation while delivering meaningful clinical and business milestones.

We believe PDS Biotechnology is well positioned at the intersection of one of oncology’s most important emerging trends: improving the effectiveness and durability of oncology therapies through precision remodeling of the tumor microenvironment. By focusing our resources on PDS0301, identifying strategic partnerships for PDS0101, and executing with financial discipline, we believe we can create meaningful long-term value for both patients and shareholders. We look forward to updating you on our progress as we move forward with this new strategy."

Sincerely,

Frank Bedu-Addo, Ph.D.
Chief Executive Officer, Director

PDS Biotechnology will announce its financial results for the quarter ending June 30, 2026, on August 13, 2026.

Mereo BioPharma Reports Second Quarter 2026 Financial Results and Provides Corporate Highlights

On August 11, 2026 Mereo BioPharma Group plc (NASDAQ: MREO) ("Mereo" or the "Company"), a clinical-stage biopharmaceutical company focused on rare diseases, reported financial results for the second quarter ended June 30, 2026, and provided an update on recent corporate highlights.

The Company is also updating its previous cash runway guidance. As of June 30, 2026, cash and cash equivalents were approximately $30 million, which are expected to fund operations into late-2027.

"The partnership with Sentynl Therapeutics which we announced earlier today marks a significant milestone for our alvelestat program and for the Company as a whole. We are now working together to refine the design of the global Phase 3 study for our potential first-in-class oral therapy for AATD-LD and look forward to a continued close collaboration during the short option period. Assuming exercise of the license option by Sentynl, we plan to initiate the Phase 3 trial in early 2027," said Denise Scots-Knight, Chief Executive Officer of Mereo BioPharma. "Additionally, alongside our partner Ultragenyx, we have had initial regulatory interactions on setrusumab with the FDA and the MHRA and we expect to be in a position to provide an update on the potential path forward by the end of this year. We finished the quarter with approximately $30 million in cash. Thanks to our careful expense management, we now expect that this cash will provide runway into late-2027, exclusive of the potential $40 million in upfront and R&D payments that we are eligible to receive on exercise of the alvelestat option by Sentynl."

Second Quarter 2026 Highlights, Recent Developments, and Anticipated Milestones

Setrusumab (UX143)

•
The Orbit and the Cosmic Phase 3 studies did not achieve statistical significance against the primary endpoints of reduction in annualized clinical fracture rate, however, both achieved high statistical significance against the key secondary endpoint of improvement in bone mineral density, as well as reductions in vertebral fractures and improvements in patient reported outcomes (PROs) associated with disease severity, pain / discomfort and daily activities, with these PRO improvements achieving statistical significance in the Orbit study. Setrusumab also achieved meaningful reductions in fractures in certain bones and in patients with higher fracture frequencies. Both studies demonstrated a safety profile consistent with that observed in previous trials.
•
Mereo and its partner, Ultragenyx Pharmaceutical, Inc. ("Ultragenyx"), are engaged with regulatory agencies to determine a potential path forward for setrusumab in pediatric OI patients and, to-date, have held discussions with the regulators in the U.S. and the U.K. The FDA indicated openness to considering alternative approaches to fracture analysis, with additional conversations needed to further define what additional clinical data would be needed to support a potential BLA. In recent communications with the MHRA, they encouraged further dialogue on any future development proposal, and we plan to have further interactions following the FDA discussions.

Alvelestat (MPH-966)

•
Mereo recently announced an option and license agreement with Sentynl Therapeutics, Inc. (Sentynl), a wholly owned subsidiary of Zydus Lifesciences Limited. Sentynl has the right to acquire a license for the U.S. commercial and global manufacturing rights to alvelestat for AATD-LD.
o
Sentynl is a California-based, commercial-stage biopharmaceutical company with three currently approved products for rare diseases.
o
Under the agreement, the companies will collaborate to refine the design of the planned global Phase 3 trial of alvelestat and to advance the manufacturing during the short option period.
•
Mereo will receive a non-refundable option fee and, on option exercise, would also be eligible to receive $40 million in upfront and R&D payments, up to $435 million in regulatory and commercial milestone payments, as well as double-digit tiered royalties on U.S. net sales of alvelestat.

•
Mereo will lead the global Phase 3 study and regulatory interactions until study completion and will retain rest-of-world commercial rights for alvelestat.
•
On exercise of the option by Sentynl, the agreement provides funding for the global Phase 3 study, which could be initiated early in 2027.

Vantictumab (OMP18R5)

•
āshibio, Inc. (āshibio), Mereo’s development and commercial partner for vantictumab, is continuing to advance toward initiation of a Phase 2 clinical trial in autosomal dominant osteopetrosis Type 2 (ADO2).
•
āshibio is responsible for the global clinical development of vantictumab. Mereo has retained European commercial rights to the product, with āshibio holding commercial rights for the rest of the world.

Second Quarter 2026 Financial Results

Total research and development ("R&D") expenses decreased by $3.6 million, from $5.4 million in the second quarter of 2025 to $1.8 million in the second quarter of 2026. The decrease was primarily due to a reduction of $2.6 million in R&D expenses for setrusumab and $1.0 million for alvelestat. The decrease in program expenses for setrusumab was primarily driven by reduction of, and delays to, investment in manufacturing and ongoing activities, including medical affairs activities in Europe during the second quarter of 2026. The decrease in program expenses for alvelestat was primarily due to completion of activities undertaken in preparation for the potential Phase 3 study during 2025.

General and administrative ("G&A") expenses decreased by $0.3 million, from $5.5 million in the second quarter of 2025 to $5.2 million in the second quarter of 2026. The decrease was primarily due to reductions of approximately $2.2 million driven by delays to investment in pre-commercial activities to lay the foundation for the potential commercial launch of setrusumab in Europe and other realized cost savings. These decreases were partially offset by the recognition of a $1.9 million reduction in expenses in the second quarter of 2025 for amounts received from our depository to reimburse certain expenses incurred by us in respect of our ADR program, whereas the corresponding amount in the current year was recognized in the first quarter of 2026.

Net loss for the second quarter of 2026 was $7.0 million, compared to $14.6 million for the second quarter of 2025, primarily reflecting reductions in R&D and G&A expenses and a lower net foreign currency translation loss.

As of June 30, 2026, the Company had cash and cash equivalents of $30.1 million, compared to $41.0 million as of December 31, 2025. The Company expects, based on current operational plans, that its existing cash and cash equivalents balance will enable it to fund its currently committed clinical trials, operating expenses, and capital expenditure requirements into late 2027. This guidance does not include any future potential payments associated with business development activity around any of the Company’s programs.

Total ordinary shares issued as of June 30, 2026 were 798,093,044. Total ADS equivalents as of June 30, 2026 were 159,618,608, with each ADS representing five ordinary shares of the Company.

Business Update

INVINCIBLE-3 Study: Phase 3 open-label, randomized study testing INT230-6 as monotherapy compared with standard-of-care ("SOC") in second- and third-line treatment of certain soft tissue sarcoma subtypes.
In April 2026, the Company initiated activities to resume enrollment in a limited number of U.S. sites in the INVINCIBLE-3 Study using an FDA-reviewed amended protocol based on important learnings from patients previously enrolled in the study. The Company paused new site activations and patient enrollment in March 2025 due to funding constraints. At that time, the trial had enrolled 21 patients, and the Company continued to treat all patients, maintain the database, conduct pharmacovigilance, and conduct other study-related activities in cooperation with its contract research organizations at significantly reduced ongoing costs. In addition, during this pause, the Company obtained important feedback and recommendations about the trial from key investigators and sarcoma thought leaders, and modifications to the protocol were made. The FDA has reviewed the amended protocol, which will be implemented for new patient enrollment. Submission of documentation necessary for restarting in the EU is in progress. Site activation and patient enrollment rates are expected to increase as sufficient funding is obtained.

INVINCIBLE-4 Study: Phase 2 open-label, randomized controlled, multicenter study to analyze the clinical activity, safety, and tolerability of INT230-6 given before SOC in patients with early-stage, operable TNBC (Cohort A) and SOC alone (Cohort B).

In July 2026, the Company restarted patient treatment in the INVINCIBLE-4 Study and is currently targeting complete enrollment by the end of 2027. The Company paused new patient enrollment in September 2025 to revise the dosing regimen for patients receiving INT230-6 in Cohort A due to some patients experiencing localized skin irritation near the tumor site. In March 2026, a protocol amendment was approved by the Swissmedic and the Swiss Ethics Committee to use a lower drug volume per tumor volume ratio and a single injection of INT230-6 in Cohort A. In August 2026, the Company opened its first site in France for accrual following EU submission of the modified protocol.
Preliminary data from the first 14 patients (seven in each cohort) showed a 71% pathological complete response ("pCR") in patients receiving INT230-6 in Cohort A and a 42% pCR in patients receiving the SOC alone (Cohort B). There was also a 44% reduction in grade 3 adverse events in Cohort A compared with Cohort B and fewer immune-related adverse events when INT230-6 was added prior to the immunochemotherapy.

Capital Raises
In March 2026, the Company established a $60 million at-the-market ("ATM") facility. During the second quarter of 2026, the Company raised net proceeds of $1.6 million under the ATM. Subsequent to June 30, 2026, the Company has raised additional net proceeds of $1.3 million under the ATM.

"We are pleased that the capital raised in 2025 and to date in 2026 provides the resources to reinitiate the Phase 3 INVINCIBLE-3 Study. In addition, during the 2025 pause, we evaluated and modified the protocol based on feedback from key investigators and sarcoma thought leaders. The FDA-reviewed amended protocol will first be implemented in select U.S. sites," stated Lewis H. Bender, Founder, President and CEO of Intensity. "In the Phase 2 INVINCIBLE-4 Study, early data show potential for an improvement in the pCR rate with a reduction in the number of grade 3 adverse events including immune-related adverse events. These preliminary findings are encouraging, and we are excited that investigators have restarted treatment in patients in Switzerland. We look forward to enrolling new patients in this study in France now that sites are being activated. Lastly, we continue to pursue potential partnerships to advance our programs, and held meetings with potential strategic partners at the BIO International Conference in late June. While early, we are pleased with the interest expressed in our science and clinical trials, and we expect to continue discussions in the second half of 2026."

Second Quarter 2026 Financial Results

Research and development expenses were $1.8 million for the second quarter of 2026, compared with $1.5 million for the same period in 2025. The increase was primarily due to higher INVINCIBLE-3 Study costs as the Company initiated activities to resume enrollment in a limited number of U.S. sites in April. The Company paused new site activations and patient enrollments in March 2025 due to funding constraints. Research and development expenses also increased due to an estimated bonus accrual during the second quarter of 2026 compared with no bonus accrual during the second quarter of 2025, which was partially offset by lower stock-based compensation.

General and administrative expenses were $1.3 million for the second quarter of 2026, compared with $1.2 million for the same period in 2025. The increase was due to an estimated bonus accrual during the 2026 quarter compared with no bonus accrual during 2025 quarter, and higher Delaware franchise costs. These increases were partially offset by lower stock-based compensation as no stock-based compensation awards were granted during the first half of 2026.

Net loss was $3.0 million for the second quarter of 2026, compared with a net loss of $2.5 million for the second quarter of 2025.

Women with aggressive forms of breast cancer, such as TNBC, are often counseled to undergo neoadjuvant (presurgical) systemic therapy to reduce the risk of the disease returning. Having a pathological complete response, meaning the absence of live cancer at the time of surgery, has been shown to result in a lower risk of disease recurrence from 50% to 16% at 5 years. Approximately 11% to 17% of breast cancers test negative for estrogen receptors ("ER"), progesterone receptors ("PR"), and overexpression of human epidermal growth factor receptor 2 ("HER2") protein, qualifying them as triple negative. There are approximately 56,000 new cases of TNBC in the US and 420,000 worldwide diagnosed each year, 85% of which are local to the breast. TNBC is considered to be more aggressive and has a poorer prognosis than other types of breast cancer, because there are fewer available targeted medicines. Most patients with local TNBC typically receive immunochemotherapy before surgery. Since the publication of Keynote-522, the standard neoadjuvant treatment for TNBC includes systemic chemotherapy (anthracyclines, cyclophosphamide, paclitaxel, carboplatin) and the anti-PD-1 monoclonal antibody pembrolizumab. pCR rates range from 50% to 65%, depending on tumor size. Rates are generally lower in the larger-sized tumors or with lymph node metastasis. The toxicity of the Keynote-522 regimen is high, with 77% of patients experiencing grade 3 or higher treatment-related adverse events, including treatment-related adverse events that lead to death in 0.5% of patients.
About Sarcoma
Soft tissue sarcoma is a rare type of cancer that starts with the growth of cells in the body’s soft tissue, such as muscle, fat, blood vessels, nerves, tendons, and linings of the joints. The disease mostly occurs in the arms, legs and abdomen. There are 197,000 patients in the US living with sarcoma and more than 100 types of soft tissue sarcoma, the treatment of which first involves surgery. Other treatments might include radiation therapy and then chemotherapy. Using the U.S. SEER database, the Company estimated that 14,400 patients have regional or distal (metastatic) leiomyosarcoma, liposarcoma, and undifferentiated pleomorphic sarcoma.
About INT230-6
INT230-6, Intensity’s lead proprietary investigational product candidate, is designed for direct intratumoral injection. INT230-6 was discovered using Intensity’s proprietary DfuseRx℠ technology platform. The drug consists of two proven, potent anti-cancer agents, cisplatin and vinblastine sulfate, and a diffusion and cell penetration enhancer molecule ("SHAO") that non-covalently conjugates to the two payload drugs, facilitating the dispersion of potent cytotoxic drugs throughout tumors and allowing the active agents to diffuse into cancer cells. These agents remain in the tumor, resulting in a favorable safety profile. In addition to local disease control and direct tumor killing, INT230-6 causes a release of a bolus of neoantigens specific to the malignancy, leading to immune system engagement and systemic anti-tumor effects. Importantly, these effects are mediated without immunosuppression, which often occurs with systemic chemotherapy.
