Financial Results – Quarter Ended June 30, 2025

Soligenix reported no revenue for the quarter ended June 30, 2025, consistent with comparable de minimis revenue during the same period of 2024.

Soligenix’s net loss was $2.7 million, or ($0.82) per share, for the quarter ended June 30, 2025, compared to $1.6 million, or ($1.31) per share, for the quarter ended June 30, 2024. This increase in net loss was primarily due to an increase in operating expenses related to ongoing clinical trials and a decrease in other income attributable to the change in the fair value of debt during the three months ended June 30, 2024 with no corresponding change in fair value during the three months ended June 30, 2025.

Research and development expenses were $1.7 million for the quarter ended June 30, 2025 as compared to $0.5 million for the same period in 2024. The increase was primarily due to costs associated with the Phase 2a study in Behçet’s Disease and the second confirmatory Phase 3 CTCL trial as well as increases in third party manufacturing.

General and administrative expenses were $1.1 million for the quarter ended June 30, 2025 as compared to $1.2 million for the same period in 2024. The decrease was primarily attributable to decreases in professional expenses.

As of June 30, 2025, the Company’s cash position was approximately $5.1 million, exclusive of approximately $1.4 million of net cash received via its ATM facility on July 1, 2025.

On August 14, 2025 RenovoRx, Inc. ("RenovoRx" or the "Company") (Nasdaq: RNXT), a life sciences company developing innovative targeted oncology therapies and commercializing RenovoCath, a novel, FDA-cleared drug-delivery device, reported its financial results and business update to shareholders for the second quarter ended June 30, 2025 (Press release, Renovorx, AUG 14, 2025, View Source [SID1234655315]).

"We are pleased to report second quarter 2025 revenue of over $400,000. This growth highlights the strong clinical need and market demand for our patented RenovoCath device as a standalone targeted drug-delivery product among both new and existing customers. We are proud of the initial organic revenue growth over the first two full quarters since launching RenovoCath commercial sales, especially since this was achieved without a dedicated sales and marketing team. With the recent hiring of Phil Stocton as our Senior Director of Sales and Market Development, our goal is to stay lean, while also continuing to build commercialization momentum. We will continue to gather important data about our market (such as such as sales cycles, activation times, individual customer preferences and other commercial matters), as we seek to grow our customer base, fulfill repeat RenovoCath orders, and position ourselves for commercial growth over the long term," said Shaun Bagai, CEO of RenovoRx.

"At the same time, we are very excited to report that the independent Data Monitoring Committee (DMC) for our ongoing Phase III TIGeR-PaC trial recently completed their review of our second pre-planned interim analysis and has recommended that we continue the study. This is great news, as we believe the DMC’s recommendation is an expression of confidence in the potential for a positive outcome in the trial overall," continued Mr. Bagai.

"With a view towards preserving the integrity of the TIGeR-PaC trial for FDA purposes, and following our review of general FDA guidance, discussions with the DMC, and consultation with regulatory advisors, we are deferring publishing our second interim data. Outside of our Chief Medical Officer, Dr. Ramtin Agah, who has been speaking directly with the DMC, our entire team will remain blinded to the interim data. We will revisit publishing the actual second interim data, most likely upon completion of the study as is common for pivotal Phase III trials. As of August 12, 2025, 95 patients have been randomized and 61 events have occurred, putting us on target to complete enrollment this year or early next year," concluded Mr. Bagai.

RenovoCath Commercialization Update

RenovoRx continued its RenovoCath commercialization progress, with thirteen cancer center customers approved to purchase the device, including several high-volume, National Cancer Institute (NCI)-designated academic and community centers, an increase from five centers in the first quarter of 2025. Four of these thirteen cancer centers have used the device in patients, and all have made repeat purchase orders subsequently. RenovoRx believes that many of the 18 cancer centers that have used RenovoCath as part of its ongoing, pivotal Phase III TIGeR-PaC trial could also be potential customers for RenovoCath after the completion of TIGeR-PaC enrollment, which is expected later this year or early next year. All of this is being accomplished in-house by RenovoRx without a dedicated sales and marketing team. RenovoRx plans to strategically add a small number of sales personnel in the second half of 2025 as it looks to widen market penetration in 2026.

RenovoRx believes that the initial total addressable market (TAM) for RenovoCath as a stand-alone device represents an estimated initial $400 million peak annual U.S. sales opportunity. Beyond historical RenovoCath usage, RenovoRx commercial efforts are already indicating the adoption of RenovoCath technology for the treatment of other solid tumors. This serves as the basis for our belief in the potential for a several-billion-dollar TAM as we expand into additional applications.

Ongoing Pivotal Phase III TIGeR-PaC Trial Update

In the TIGeR-PaC trial, RenovoRx is evaluating its first investigational drug-device combination oncology product candidate which uses the proprietary Trans-Arterial Micro-Perfusion (TAMP) therapy platform enabled by RenovoCath for the treatment of locally advanced pancreatic cancer (LAPC). RenovoRx’s combination product candidate utilizes RenovoCath for the intra-arterial administration of the chemotherapy gemcitabine (or IAG).

The current protocol and statistical analysis plan for the Phase III TIGeR-PaC trial requires 114 randomized patients, with 86 events, or deaths, necessary to complete the final analysis.

In the second quarter of 2025, the 52nd death triggered the second pre-planned interim analysis to be reviewed by the independent Data Monitoring Committee. The DMC has concluded its review and has recommended that the Company continue with the trial. To avoid compromising the integrity of the trial with the FDA, and after discussions with the DMC and consultation with its regulatory advisors, RenovoRx elected to defer publishing the interim data. RenovoRx will revisit publishing the actual second interim data, most likely upon completion of the study as is common for pivotal Phase III trials.

Second Quarter 2025 and Subsequent Key Highlights

During the second quarter of 2025, RenovoRx increased production of the RenovoCath device to meet increased demand for the targeted delivery of diagnostic and/or therapeutic agents from oncologists and interventional radiologists. The principal manufacturer of RenovoCath devices is Medical Murray Inc., based in the U.S. in North Barrington, IL.

RenovoRx highlighted strong progress in its commercialization efforts. Since launching its commercial efforts in December 2024, RenovoRx has established commercial momentum for RenovoCath, with thirteen cancer center customers approved to purchase the device, including several high-volume, National Cancer Institute (NCI)-designated academic and community centers, an increase from five centers in the first quarter of 2025. Four of these thirteen cancer centers have used the device in patients, and all have made repeat purchase orders subsequently.

This momentum highlights the growing clinical demand across the United States for novel, localized solid tumor drug-delivery options beyond methods like systemic intravenous delivery of chemotherapy. RenovoRx believes that many of the 18 cancer centers that have used RenovoCath as part of its ongoing, pivotal Phase III TIGeR-PaC trial could also be potential customers for RenovoCath after the completion of TIGeR-PaC enrollment, which is expected later this year or early next year.

To coordinate, execute, and expand its commercial efforts for RenovoCath, subsequent to the quarter, RenovoRx hired Philip Stocton as Senior Director of Sales and Market Development. Mr. Stocton brings over 25 years of experience in MedTech sales, marketing, and leadership from various commercial positions at Terumo, Johnson & Johnson, Varian (acquired by Siemens), and, most recently, Sirtex Medical. Over the past 10 years, he has specialized in interventional oncology in both domestic and international roles. Prior to his hiring, Mr. Stocton had been consulting for RenovoRx in connection with its RenovoCath commercial launch planning efforts.

During the quarter, RenovoRx initiated patient enrollment with Johns Hopkins Medicine for the Phase III TIGeR-PaC clinical trial, becoming the newest addition to a distinguished network of clinical cancer sites across the United States participating in the trial.

RenovoRx also received an Issue Notification from the U.S. Patent and Trademark Office (USPTO) indicating that U.S. patent No. 12,290,564 became effective on May 6. This patent, titled "Methods for Treating Tumors," expands protection of methods for drug delivery with RenovoRx’s TAMP therapy platform, enabled by RenovoCath. The patent covers new methods for treating a tumor by delivering drugs locally to a region of an artery or blood vessel that is near the tumor after treating this region to reduce the microvasculature. The new patent provides protection through November of 2037.

Subsequent to the quarter, RenovoRx launched a multi-center post-marketing registry study to follow patients undergoing cancer treatment delivered by its RenovoCath device to solid tumors. The PanTheR study is an important initiative aimed at evaluating the safety and effectiveness of RenovoCath in real-world clinical settings. This multi-center, post-marketing observational registry study is designed to assess long-term safety and survival outcomes in patients with solid tumors who receive targeted drug delivery via RenovoCath. By collecting real-world data on the use of RenovoCath across a broader range of tumor types, PanTheR aims to provide valuable insights into patient outcomes and support the generation of additional safety data.

Financial Highlights for the Second Quarter Ended June 30, 2025

Revenue: RenovoRx reported second quarter revenues of approximately $422,000 from commercial sales of the RenovoCath device, driven by new customer purchase orders and early repeat orders from our initial sites. June 30, 2025 marked our second full quarter of revenue generation from RenovoCath sales.

Cash Position: As of June 30, 2025, the Company had $12.3 million in cash and cash equivalents. The Company’s plan is for revenues from RenovoCath sales to reduce its burn rate over time. The Company believes that cash as of June 30, 2025 will fully fund both ongoing RenovoCath scale-up efforts and additional progress towards the completion in the Phase III TIGeR-PaC trial.

R&D Expenses: Research and development expenses were $1.4 million, for the quarter ended June 30, 2025, compared to $1.5 million for the quarter ended June 30, 2024. The $0.1 million decrease was primarily driven by a decrease in other clinical and regulatory expenses including an allocation of selling, general and administrative expenses to research and development of $0.2 million. This decrease was offset by an increase in non-recurring engineering costs to scale manufacturing and the development of our next generation RenovoCath delivery system by $0.1 million to support and expand our commercial program.

SG&A Expenses: Selling, general, and administrative expenses were approximately $1.5 million, for the quarter ended June 30, 2025, remaining relatively unchanged from the same period in the prior year.

Net Loss: Net loss was $2.9 million for the quarter ended June 30, 2025, compared to a net loss of $2.4 million for the quarter ended June 30, 2024. The $0.5 million increase was primarily due to the change in the fair value of the warrant liability of $0.9 million offset by a decrease in loss from operations of $0.4 million.

Shares Outstanding: As of August 11, 2025, shares of common stock outstanding totaled 36,645,884.

"We are invigorated by the progress we’re making, particularly in our ongoing clinical trials, where we’re seeing that MICVO’s unique mechanism as an extracellular targeted ADC has the potential to transform the treatment of advanced solid tumors," said Lara S. Sullivan, M.D., President, Chief Executive Officer and Chief Medical Officer of Pyxis Oncology. "The encouraging clinical and preclinical data observed to date suggest that MICVO may offer a differentiated treatment approach as both a monotherapy and in combination with pembrolizumab for HNSCC and other advanced solid tumors. We look forward to evaluating the emerging clinical data as we continue to advance this novel ADC."

Pipeline Updates

•
Pyxis Oncology anticipates having preliminary data from the Part 2 monotherapy expansion cohorts of the ongoing Phase 1 clinical trial evaluating MICVO in 2L and 3L R/M HNSCC patients who have received prior platinum and PD-1 inhibitor therapy in the second half of 2025. Preliminary data from the trial in 2L and 3L R/M HNSCC patients who have received prior EGFRi and PD-1 inhibitor therapy are anticipated in the first half of 2026. R/M HNSCC continues to be an area of high medical need despite potential improvements in treatment options.

•
Pyxis Oncology anticipates having preliminary data from the Phase 1/2 combination study of MICVO in combination with Merck’s anti-PD-1 therapy, KEYTRUDA (pembrolizumab), in R/M HNSCC and other advanced solid tumors in the second half of 2025.

•
In July 2025, Pyxis Oncology received a $2.8 million ($3 million milestone payment, less $0.2 million of tax in China) milestone payment from Simcere Pharmaceutical Group Limited ("Simcere") for the approval of suvemcitug (BD0801) in China by the National Medical Products Administration. The Company is eligible to receive mid to high single-digit percentage royalties on net sales of suvemcitug in China, under the terms of the Company’s license and collaboration agreement. In addition to suvemcitug, Pyxis Oncology retains rights to two other antibodies in development by Apexigen’s licensees, discovered through the APXiMAB platform.

Second Quarter 2025 Financial Results

•
As of June 30, 2025, Pyxis Oncology had cash and cash equivalents, including restricted cash, and short-term investments, of $90.4 million. The Company believes that its current cash, cash equivalents, restricted cash and short-term investments will be sufficient to fund its operations into the second half of 2026.

•
Revenues for the quarter ended June 30, 2025 were $2.8 million, compared to $0 for the quarter ended June 30, 2024. During the quarter, we recognized $2.8 million of milestone revenue ($3 million of milestone less $0.2 million of tax in China) related to regulatory approval of suvemcitug in China. The regulatory milestone was pursuant to an out-licensing and collaboration agreement between our subsidiary company, Apexigen, and Simcere, for the development and commercialization of suvemcitug for oncology in China.

•
Research and development expenses were $17.1 million for the quarter ended June 30, 2025, compared to $14.0 million for the quarter ended June 30, 2024. The increase in expenses of $3.1 million was due to increased manufacturing of drug product and drug substance and clinical trial-related expenses for monotherapy and combination therapy of MICVO aggregating to $3.8 million, partially offset by reduction in expenses related to PYX-106 by $1.1 million as the clinical development of PYX-106-101 was paused in December 2024.

•
General and administrative expenses were $5.4 million for the quarter ended June 30, 2025, compared to $6.1 million for the quarter ended June 30, 2024. The decrease was primarily due to lower corporate insurance costs, lower facilities costs and decrease in legal, professional, and consulting fees.

•
Net loss was $18.4 million, or ($0.30) per common share, for the quarter ended June 30, 2025, compared to $17.3 million, or ($0.29) per common share, for the quarter ended June 30, 2024. Excluding non-cash stock-based compensation expense, the net loss for the quarter ended June 30, 2025 was $15.3 million, compared to net loss of $14.4 million for the quarter ended June 30, 2024.

•
As of August 13, 2025, the outstanding number of shares of Common Stock of Pyxis Oncology was 62,018,135.

"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 Phio Pharmaceuticals Corp. (NASDAQ: PHIO) is a clinical-stage biopharmaceutical company developing therapeutics using its proprietary INTASYL siRNA gene silencing technology to eliminate cancer, reported its financial results for the quarter ended June 30, 2025 and provided a business update (Press release, Phio Pharmaceuticals, AUG 14, 2025, View Source [SID1234655312]).

Recent Corporate Updates

PH-762 Clinical Progress

Phio’s ongoing Phase 1b dose escalation clinical trial (NCT 06014086) is designed to evaluate the safety and tolerability of neoadjuvant use of intratumoral PH-762 in Stages 1, 2 and 4 cutaneous squamous cell carcinoma (cSCC), Stage 4 melanoma, and Stage 4 Merkel cell carcinoma. To date, a total of 15 patients with cutaneous carcinomas have been treated across four cohorts in the Phase 1b trial. These cohorts included 13 patients with cSCC, one patient with metastatic melanoma and one patient with metastatic Merkel cell carcinoma. There have been no dose-limiting toxicities or clinically relevant treatment-emergent adverse effects in the patients who received intratumoral PH-762 in this trial. Moreover, PH-762 has been well tolerated in all enrolled patients in each escalating dose cohort. No patients exhibited clinical progression of disease during the treatment phase of this trial.

The cumulative pathologic responses in the 13 patients with cSCC include five with complete response (100% clearance), one patient with a near complete response (>90% clearance), one with a partial response (>50% clearance) and six patients with a pathologic non-response (< 50% clearance).

The Merkel cell carcinoma patient with stage 4 metastatic disease had a pathological partial response (>50% clearance). The melanoma patient was a non-responder (<50% clearance).

Phio is now enrolling what is expected to be the 5th and final cohort in the Phase 1b trial.

In addition, the Company entered into a comprehensive drug substance development services agreement with a U.S. manufacturing company. The company will provide analytical and process development and cGMP manufacture of Phio’s lead development compound PH-762.

Scientific News

In May 2025, Phio delivered a podium presentation for its INTASYL self-delivering siRNA technology at the Society of Investigative Dermatology (SID).
