"In the second quarter we focused on advancing BDC-4182, the first next-generation Boltbody ISAC in our pipeline," said Willie Quinn, President and Chief Executive Officer. "We are now conducting a Phase 1 dose-escalation study for patients with gastric and gastroesophageal cancer in Australia, and will expand to other countries in the second half of 2025. We look forward to presenting initial data in the first half of 2026. We also continue to seek a partner for further development of our dectin-2 agonist antibody BDC-3042, which demonstrated activity in lung cancer patients in the form of a partial response (PR) at the highest dose tested. Patients at the highest doses also had a strong immune response consistent with our expectations based on preclinical data."

Recent Highlights and Anticipated Milestones

•
Our BDC-4182 Phase 1 study opened for enrollment for patients with gastric and gastroesophageal cancer in the first half of 2025. BDC-4182 is a next-generation Boltbody ISAC clinical candidate targeting claudin 18.2, a clinically validated target in oncology with expression in gastric/gastroesophageal junction cancer, pancreatic cancer, and other tumor types. Preclinically, monotherapy treatment with BDC-4182 generated complete regressions in multiple models and BDC-4182 was tolerated in toxicology studies. BDC-4182 outperformed cytotoxic claudin 18.2 ADCs, using MMAE or Topo1, in multiple preclinical studies.
•
Collaborations with Genmab and Toray continue to progress. Genmab and Bolt are advancing multiple development candidates , while the companies also continue research and development on additional programs. The Toray collaboration combines the Company’s immunostimulatory linker-payloads with Toray antibodies targeting Caprin-1, a tumor-specific antigen that is strongly expressed on the cell membrane in multiple solid tumor types.
•
Seeking a partner for further BDC-3042 development. In May, Bolt hosted a KOL conference call with BDC-3042 investigator Dr. Dumbrava to discuss the results from the Phase 1 dose-escalation clinical study of BDC-3042 that were presented at the American Associates for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting that took place in April 2025.

About the Boltbody Immune-Stimulating Antibody Conjugate (ISAC) Platform
Bolt Biotherapeutics’ Boltbody ISAC platform harnesses the precision of antibodies with the power of the innate and adaptive immune system to generate a productive anti-cancer response. Each Boltbody ISAC candidate comprises a tumor-targeting antibody, a non-cleavable linker, and a proprietary immune stimulant. The antibody is designed to target one or more markers on the surface of a tumor cell and the immune stimulant is designed to recruit and activate myeloid cells. Activated myeloid cells initiate a positive feedback loop by releasing cytokines and chemokines, chemical signals that attract other immune cells and lower the activation threshold for an immune response. This increases the population of activated immune system cells in the tumor microenvironment and promotes a robust immune response with the goal of generating durable therapeutic responses for patients with cancer.

On August 14, 2025 Prelude Therapeutics Incorporated (Nasdaq: PRLD), a clinical-stage precision oncology company, reported its financial results for second quarter ended June 30, 2025, and provided an update on its clinical development pipeline and other corporate developments (Press release, Prelude Therapeutics, AUG 14, 2025, View Source [SID1234655313]).

"From the discovery of first-in-class highly selective SMARCA2 degraders through Phase 1 studies in biomarker selected population of patients, Prelude demonstrated exemplary execution of our SMARCA2 program to deliver a potentially novel treatment option for patients with aggressive cancers harboring SMARCA4 deletion," stated Kris Vaddi, Ph.D., Chief Executive Officer of Prelude. "This past quarter, we completed our Phase 1 dose escalation of PRT3789 (IV), both as monotherapy and in combination with docetaxel. With the knowledge and experience gained through PRT3789 clinical development, we were able to expeditiously advance our oral program, PRT7732, which began in the fourth quarter of 2024. I am pleased with the progress made to date with PRT7732, which is currently enrolling our seventh dose cohort of 125 mg."

Vaddi continued, "We’ve decided to pause further development of PRT3789, and focus solely on PRT7732 as our go-forward strategy for our SMARCA2 Program. While PRT3789 demonstrated initial proof of concept for the mechanism, a number of considerations – including the potential need for higher target coverage throughout the dosing interval, and capital needs to continue to advance both agents – contributed to this decision. The clinical profile observed to date with PRT7732 including oral once daily dosing, safety and tolerability, oral exposures, and >90% target degradation positions us well to explore the potential for this mechanism in SMARCA4 deleted cancers and determine the path forward for continued development by year end."

Continued Vaddi, "We’ve made significant progress across our core research and development organization, while employing disciplined capital management through resource allocation and headcount management throughout the Company. Notably, we’ve continued to advance our KAT6A degrader program, on track for IND filing in the first half of 2026, presented preclinical data on mCALR-targeted ADCs and continued progress with our partner AbCellera related to precision ADCs."

Clinical Program Updates and Upcoming Milestones

SMARCA2 Degrader Development Program

PRT3789 – A first-in-class, highly selective, intravenous SMARCA2 degrader

PRT3789 is designed to treat patients with a SMARCA4 mutation. Patients with SMARCA4-mutated cancer, a particularly aggressive form of the disease, have a very poor clinical prognosis. Approximately 10% of all non-small cell lung cancers and 5% of all cancers broadly, harbor a SMARCA4 mutation. In NSCLC, these patients tend to have poor response to standard of care chemoimmunotherapy and are largely ineligible for other targeted therapies. We believe that this represents an area of high unmet medical need.

PRT3789 has completed Phase 1 clinical development in patients with biomarker selected SMARCA4-mutated cancers. The Company anticipates providing updated data from the Phase 1 study by year-end 2025. Based on the totality of the data and available resources, the Company would only advance the program in the context of a partnership and will be focusing internal resources solely on PRT7732.

PRT7732 – A potent, highly selective and orally bioavailable SMARCA2 degrader

PRT7732 is a highly selective and orally bioavailable SMARCA2 degrader with a distinct chemical composition to PRT3789. In the fourth quarter of 2024, the Company initiated and enrolled the first patients in a phase 1 multi-dose escalation trial of PRT7732 (NCT06560645) in biomarker selected SMARCA4 mutated cancers. Enrollment continues to advance rapidly, and the Company is currently enrolling patients in the seventh dose escalation cohort (125 mg once daily). The Company expects to provide an initial first-in-human data update including PK/PD, safety and an initial look at clinical activity at biologically relevant doses by year end 2025.

Highly selective KAT6A oral degrader program

KAT6 is an emerging and recently validated target in the treatment of ER+ breast cancer and other malignancies. Prelude discovered and is developing the industry’s first – based on currently published patents and literature – highly potent, selective and orally bioavailable KAT6A selective degraders. The Company is now advancing a development candidate and remains on track to file an IND in the first half 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 recently presented preclinical data validating this hypothesis at the AACR (Free AACR Whitepaper) Annual Meeting 2025. The presentation can be found at Publications – Prelude Therapeutics.

Precision ADCs with SMARCA2/4 dual degrader payload

Prelude is developing potent SMARCA2/4 dual degraders that robustly inhibit cancer cell growth and induce cell death across multiple cancer types as payloads for precision ADCs. The Company presented the first preclinical data from its precision ADC platform at the 36th EORTC-NCI-AACR (Free EORTC-NCI-AACR Whitepaper) Symposium in October. These data demonstrated that SMARCA2/4 degrader antibody conjugates have potential for significantly better in vivo efficacy and tolerability when compared to traditional cytotoxic ADCs when tested head-to-head in xenograft models. The presentation can be found at Publications – Prelude Therapeutics.

Mutated Calreticulin (mCALR)

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 myelofibrosis (MF) and essential thrombocythemia (ET). Recently, a mCALR-targeted monoclonal antibody demonstrated robust clinical activity in high-risk ET patients. Prelude is seeking to further optimize this modality by developing mCALR-targeted precision ADCs using the Company’s proprietary degrader payloads. The Company presented the first preclinical data from this discovery effort at the European Hematology Association (EHA) (Free EHA Whitepaper) 2025 Congress in June. The presentation can be found at Publications – Prelude Therapeutics.

Second Quarter 2025 Financial Results 

Cash, Cash Equivalents, Restricted Cash and Marketable Securities:

Cash, cash equivalents, restricted cash and marketable securities as of June 30, 2025 were $77.3 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 2026.

Research and Development (R&D) Expenses:

For the second quarter of 2025, R&D expense decreased to $25.8 million from $29.5 million for the prior year period. Included in the R&D expense for the three months ended June 30, 2025 was $2.2 million of non-cash expense related to stock-based compensation, including employee stock options, compared to $3.4 million for the three months ended June 30, 2024. Research and development expenses decreased primarily due to a decrease in expense related to our SMARCA2 clinical trials. 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.

General and Administrative (G&A) Expenses:

For the second quarter of 2025, G&A expenses decreased to $6.4 million from $7.7 million for the prior year period. Included in general and administrative expenses for the three months ended June 30, 2025, was $1.6 million of non-cash expense related to stock-based compensation, including employee stock options, compared to $2.7 million for the three months ended June 30, 2024. The decrease in general and administrative expenses was primarily due to a decrease in stock-based compensation due to lower valuation on more recent grants due to the decrease in our stock price.

On August 14, 2025 Candel Therapeutics, Inc. (Candel or the Company) (Nasdaq: CADL), a clinical-stage biopharmaceutical company focused on developing multimodal biological immunotherapies to help patients fight cancer, reported financial results for the second quarter ended June 30, 2025, and provided a corporate update (Press release, Candel Therapeutics, AUG 14, 2025, View Source [SID1234655283]).

Second Quarter 2025 & Recent Highlights

•
CAN-2409 – Prostate Cancer
•
In an oral presentation at the 2025 ASCO (Free ASCO Whitepaper) Annual Meeting on June 3, 2025, in Chicago, IL, the Company reported phase 3 results from the CAN-2409 clinical trial in intermediate-to-high risk localized prostate cancer. The primary endpoint, agreed with the U.S. Food and Drug Administration (FDA) under a Special Protocol Assessment (SPA), was met, with a statistically significant improvement of 30% in disease-free survival among CAN-2409 recipients (HR 0.70, p=0.0155) when compared to placebo, both in combination with standard-of-care external beam radiation therapy. This data was supported by secondary endpoints.
•
On June 3, 2025, Candel hosted a conference call featuring perspectives from leading prostate cancer specialists, John E. Sylvester, M.D., Atlantic Urology Clinics, Myrtle Beach, South Carolina, and Ronald F. Tutrone, Jr., M.D., FACS, CPI, National Medical Director of Clinical Research, United Urology Group, Towson, Maryland. Both physicians were principal investigators on the trial. The call replay can be accessed here.
•
This phase 3 study was conducted under a SPA agreed with the FDA, meaning that certain data generated from this study could be sufficient for the Company to seek regulatory approval for CAN-2409 in this indication.
•
The Company is advancing its pre-BLA readiness, including through Chemistry, Manufacturing, and Controls (CMC) activities and documentation, and preparation of clinical study reports.
•
In May, the Company received RMAT Designation from the FDA for CAN-2409 for the treatment of newly diagnosed, localized prostate cancer in patients with intermediate-to-high-risk disease. The FDA previously granted Fast Track Designation for CAN-2409 for the treatment of localized primary prostate cancer.
•
The Company continues to work toward a BLA submission for CAN-2409 in prostate cancer in Q4 2026.
•
CAN-2409 – Non-Small Cell Lung Cancer (NSCLC)

•
In March, the Company reported positive overall survival data from its phase 2a clinical trial of CAN-2409 in patients with stage III/IV NSCLC inadequately responding to ICI treatment.
•
In patients with an inadequate response to ICI treatment (Cohorts 1+2, n=46), median overall survival (mOS) was 24.5 months.
•
In patients with progressive disease, despite ICI treatment (Cohort 2, n=41), mOS was 21.5 months, which is markedly longer than the 9.8–11.8 months of survival reported in published literature1,2 in the same patient population receiving standard of care of docetaxel chemotherapy.
•
37% of patients with progressive disease at enrollment were still alive > 24 months after CAN-2409 treatment at the time of the March 3, 2025 data cut, suggesting a long tail of survival. 14/15 patients with overall survival > 24 months and 9/9 patients with overall survival > 30 months had non-squamous NSCLC.
•
In patients with non-squamous NSCLC and progressive disease despite ICI (cohort 2, n=33), observed mOS was 25.4 months after CAN-2409 treatment.
•
A decrease in the size of uninjected tumors was observed in 69% of patients with multiple lesions (n=35), indicating that a local injection is associated with a systemic anti-tumor immune response.
•
CAN-2409 maintained its generally favorable safety and tolerability profile throughout the extended follow-up period.
•
The FDA previously granted Fast Track Designation for CAN-2409 for the treatment of NSCLC.
•
CAN-2409 – Pancreatic Cancer
•
In February 2025, the Company reported positive overall survival data from the randomized, controlled, phase 2a clinical trial of CAN-2409 in borderline resectable pancreatic ductal adenocarcinoma (PDAC).
•
Patients who had received experimental treatment with CAN-2409 and chemoradiotherapy achieved a mOS of 31.4 months versus 12.5 months observed in the control arm treated with chemoradiotherapy.
•
Notably, three out of seven patients in the CAN-2409 arm were long-term survivors and remained alive at 66.0, 63.6, and 35.8 months post-treatment, whereas only one out of six patients from the control arm was still alive at the time of data cut-off (February 20, 2025). Patients in the CAN-2409 arm were stable at the time of last follow up with minimal maintenance therapy and, despite previous recurrence, experienced extended and ongoing post-progression survival, further highlighting the sustained benefit of CAN-2409, even in metastatic disease.
•
The FDA previously granted Orphan Drug Designation and Fast Track Designation for CAN-2409 in borderline resectable PDAC.

•
The EMA granted Orphan Designation for CAN-2409 for the treatment of pancreatic cancer in July 2025.
•
Recent Corporate Events
•
In June 2025, the Company completed a registered direct offering, of approximately 3.2 million shares of its common stock, to a select group of existing healthcare-focused institutional investors, executive officers, and directors of the Company, at a price per share of $4.67, resulting in gross proceeds of approximately $15 million, before deducting offering expenses payable by the Company.
•
In June 2025, the Company appointed Charles Schoch as Chief Financial Officer (CFO). Mr. Schoch previously served as interim CFO of Candel. He will continue to be instrumental as the Company advances its clinical pipeline and prepares for BLA submission of CAN-2409 in localized prostate cancer, anticipated in Q4 2026.

•
Submission of BLA for CAN-2409 in prostate cancer expected in Q4 2026.
Financial Results for the Second Quarter Ended June 30, 2025

Research and Development Expenses: Research and development expenses were $7.0 million for the second quarter of 2025 compared to $5.0 million for the second quarter of 2024. The increase was primarily due to an increase in manufacturing costs in support of the Company’s CAN-2409 programs, partially offset by a decrease in employee-related expenses, which was driven primarily from a reduction in stock-based compensation expense. Research and development expenses included a non-cash stock compensation expense of $0.4 million for the second quarter of 2025 compared to a non-cash stock compensation expense of $1.3 million for the second quarter of 2024.

General and Administrative Expenses: General and administrative expenses were $4.2 million for the second quarter of 2025, compared to $3.6 million for the second quarter of 2024. The increase was primarily due to an increase in commercial readiness costs as well as higher professional and consulting fees. General and administrative expenses included non-cash stock compensation expense of $0.6 million for both the second quarter of 2025 and the second quarter of 2024.

Net Loss: Net loss for the second quarter of 2025 was $4.8 million compared to a net loss of $22.2 million for the second quarter of 2024 and included net other income of $6.4 million and net other expense of $13.7 million, respectively. The decrease in net loss was primarily related to the change in the fair value of the Company’s warrant liability.

Cash Position: Cash and cash equivalents, as of June 30, 2025, were $100.7 million compared to $102.7 million as of December 31, 2024. Based on current plans and assumptions, the Company expects that its existing cash and cash equivalents will be sufficient to fund operations into Q1 2027, including the Company’s expected submission of the BLA for CAN-2409 in intermediate-to-high-risk prostate cancer to the FDA in Q4 2026.

About CAN-2409

CAN-2409 (aglatimagene besadenovec), Candel’s most advanced multimodal biological immunotherapy candidate, is an investigational, off-the-shelf, replication-defective adenovirus designed to deliver the herpes simplex virus thymidine kinase (HSV-tk) gene to a patient’s tumor. After intratumoral administration, HSV-tk enzyme activity results in conversion of prodrug (valacyclovir) into deoxyribonucleic acid (DNA)-incorporating nucleotide analogs, leading to immunogenic cell death in cells exhibiting DNA damage and proliferating cells, with subsequent release of a variety of tumor (neo)antigens in the tumor microenvironment. At the same time, the adenoviral serotype 5 capsid protein promotes inflammation through the induction of expression of pro-inflammatory cytokines, chemokines, and adhesion molecules. Together, this regimen is designed to induce an individualized and specific CD8+ T cell-mediated response against the injected tumor and uninjected distant metastases for broad anti-tumor activity, based on in situ immunization against a variety of tumor antigens. CAN-2409 has the potential to treat a broad range of solid tumors. Encouraging monotherapy activity as well as combination activity with standard of care radiotherapy, surgery, chemotherapy, and immune checkpoint inhibitors have previously been shown in several preclinical and clinical settings. More than 1,000 patients have been dosed with CAN-2409 with a favorable tolerability profile to date, supporting the potential for combination with standard of care, when indicated.

About CAN-3110

CAN-3110 is a first-in-class, replication-competent herpes simplex virus-1 (HSV-1) next-generation oncolytic viral immunotherapy candidate designed for dual activity for oncolysis and immune activation in a single therapeutic. CAN-3110 is being evaluated in a phase 1b clinical trial in patients with rHGG. In October 2023, the Company announced that Nature published results from this ongoing clinical trial. CAN-3110 was well tolerated with no dose-limiting toxicity reported. In the clinical trial, the investigators observed improved median overall survival compared to historical controls after a single CAN-3110 injection in this therapy-resistant condition.3 The Company and academic collaborators are currently evaluating the effects of repeat CAN-3110 injections in rHGG, supported by the Break Through Cancer foundation. CAN-3110 has previously received FDA Fast Track Designation and Orphan Drug Designation for the treatment of rHGG.
