On July 28, 2025 UroGen Pharma Ltd. (Nasdaq: URGN), a biotech company dedicated to developing and commercializing innovative treatments for urothelial and specialty cancers, reported the publication in Reviews in Urology of results from a Phase 3b study evaluating the feasibility of administering ZUSDURI (mitomycin) for intravesical solution (formerly known as UGN-102) in the home setting (Press release, UroGen Pharma, JUL 28, 2025, View Source [SID1234654575]). The study, titled "Home Instillation of UGN-102 for Primary Chemoablation of Recurrent Low-Grade Intermediate-Risk Non-Muscle Invasive Bladder Cancer: A Single-Arm, Open-Label, Phase 3b Trial," demonstrated that trained home health professionals (HHPs) can safely and effectively administer ZUSDURI outside of a traditional clinical setting.

"The ability to deliver this treatment safely and effectively at home has the potential to ease the burden on patients and reduce reliance on hospital or clinic resources," said David Morris, MD, lead investigator and practicing urologist at Urology Associates, PC, Nashville, TN. "As physicians, we’re always looking for ways to provide effective care with greater comfort and convenience. These findings represent an important step in that direction."

The study assessed the feasibility, safety, and early efficacy of at-home instillations of ZUSDURI in patients with recurrent LG-IR-NMIBC. Six of eight patients (75%) completed all six scheduled treatments, with five of those six patients indicating they would recommend the home-based approach to others. A 75% complete response (CR) rate was observed at three months (95% CI: 34.9, 96.8), and no new safety concerns were identified. Feasibility questionnaires were completed by patients, and HHPs throughout the study. After each home instillation, patients rated their experience based on comfort, safety, communication, preference compared to office instillation, and overall satisfaction. At study end, they were also asked whether they would recommend home instillation of ZUSDURI to other patients and as an alternative to undergoing TURBT. Investigators assessed the clinical comparability of home versus in-office administration. HHPs provided feedback after each visit and at the study’s conclusion, reporting on their comfort with the procedure, perceived difficulty, and adequacy of training and support.

"This patient-centered approach to care reflects our commitment to redefining how urologic cancers are treated, offering patients access to effective and convenient treatment options," said Mark Schoenberg, MD, Chief Medical Officer, UroGen. "The ability to potentially administer ZUSDURI safely in the home represents a meaningful advancement for patients and caregivers alike, especially those who may face challenges traveling to frequent clinic visits."

In this study, ZUSDURI was administered via urinary catheter once weekly for six weeks, with the first dose administered in the clinic, followed by five at-home instillations by HHPs. Investigators found no meaningful differences between home and office instillation for most patients. The safety profile was consistent with previous studies, with most adverse events being mild-to-moderate urinary symptoms.

Study limitations include, among others, the small sample size of eight patients, and the open-label and single-arm design.

About ZUSDURI

ZUSDURI (mitomycin) for intravesical solution is an innovative drug formulation of mitomycin, approved for the treatment of adults with recurrent LG-IR-NMIBC. Utilizing UroGen’s proprietary RTGel technology, a sustained release, hydrogel-based formulation, ZUSDURI is delivered directly into the bladder in an out-patient procedure by a trained healthcare professional using a urinary catheter to enable the treatment of tumors by non-surgical means. Patients can visit ZUSDURI.com for more information.

About Non-Muscle Invasive Bladder Cancer (NMIBC)

LG-IR-NMIBC affects around 82,000 people in the U.S. every year and of those, an estimated 59,000 are recurrent. Bladder cancer primarily affects older populations with increased risk of comorbidities, with the median age of diagnosis being 73 years. Guideline recommendations for the management of NMIBC include TURBT as the standard of care. Up to 70 percent of NMIBC patients experience at least one recurrence, and LG-IR-NMIBC patients are even more likely to recur and face repeated TURBT procedures.

"Exelixis continued to execute on our corporate objectives in the second quarter of 2025, delivering on key commercial, development and pipeline milestones," said Michael M. Morrissey, Ph.D., President and Chief Executive Officer, Exelixis. "While early in the launch, we’re very pleased with the reception that CABOMETYX has received in advanced neuroendocrine tumors (NET). Our commercial team rapidly mobilized on the U.S. NET launch following approval in March, capturing a leading share of new patient starts among oral therapies in second-line and later settings with NET representing approximately four percent of our overall CABOMETYX business in the second quarter. We will continue to track the launch trajectory and provide updates to our 2025 full year financial guidance, as appropriate."

Dr. Morrissey continued: "Turning to the zanzalintinib development program, in June, we announced positive topline results from the STELLAR-303 pivotal study in colorectal cancer. We plan to discuss these results with regulators with the intention of filing for approval in this indication as quickly as possible. In May, we completed enrollment into the STELLAR-304 pivotal study in non-clear cell renal cell carcinoma with top-line results expected in the first half of 2026, depending on study event rates. Based on our evaluation of emerging data from the phase 2 portion of the STELLAR-305 study in advanced squamous cell carcinoma of the head and neck, emerging competition in this indication and assessment of other potentially larger commercial opportunities, we have made the decision not to proceed to the phase 3 portion of the trial. We also initiated the STELLAR-311 pivotal study in advanced NET during the quarter and plan to announce an additional wave of zanzalintinib pivotal trials in the coming months. Finally, our early-stage pipeline is advancing quickly with phase 1 clinical studies ongoing for our XL309, XB010 and XB628 programs, and XB371 moving into clinical investigation. As we look ahead to the second half of the year, I’d like to thank the entire Exelixis team for their continued execution across our business, and for their dedication to our mission to help cancer patients recover stronger and live longer."

Second Quarter 2025 Financial Results

Total revenues for the quarter ended June 30, 2025 were $568.3 million, as compared to $637.2 million for the comparable period in 2024.

Total revenues for the quarter ended June 30, 2025 included net product revenues of $520.0 million, as compared to $437.6 million for the comparable period in 2024. The increase in net product revenues was primarily due to an increase in sales volume.

Collaboration revenues, composed of license revenues and collaboration services revenues, were $48.2 million for the quarter ended June 30, 2025, as compared to $199.6 million for the comparable period in 2024. The decrease in collaboration revenues was primarily related to a $150.0 million commercial milestone recognized during the second quarter of 2024 in connection with Ipsen achieving $600 million in cumulative net sales of cabozantinib in its related license territory over four consecutive quarters.

Research and development expenses for the quarter ended June 30, 2025 were $200.4 million, as compared to $211.1 million for the comparable period in 2024. The decrease in research and development expenses was primarily related to decreases in manufacturing costs to support our development candidates and clinical trial costs, partially offset by increases in stock-based compensation, consulting and outside services, and personnel expenses.

Selling, general and administrative expenses for the quarter ended June 30, 2025 were $134.9 million, as compared to $132.0 million for the comparable period in 2024. The increase in selling, general and administrative expenses was primarily related to increases in marketing expenses, stock-based compensation, and personnel expenses, partially offset by a decrease in corporate giving.

Provision for income taxes for the quarter ended June 30, 2025 was $45.6 million, as compared to $66.7 million for the comparable period in 2024.

GAAP net income for the quarter ended June 30, 2025 was $184.8 million, or $0.68 per share, basic and $0.65 per share, diluted, as compared to GAAP net income of $226.1 million, or $0.78 per share, basic and $0.77 per share diluted, for the comparable period in 2024. GAAP net income per share for the quarter ended June 30, 2025 was favorably impacted by lower weighted-average common shares outstanding for the quarter ended June 30, 2025, as compared to the comparable period in 2024, as a result of the stock repurchase programs.

Non-GAAP net income for the quarter ended June 30, 2025 was $212.6 million, or $0.78 per share, basic and $0.75 per share, diluted, as compared to non-GAAP net income of $245.6 million, or $0.85 per share, basic and $0.84 per share diluted, for the comparable period in 2024.

Non-GAAP Financial Measures

To supplement Exelixis’ financial results presented in accordance with U.S. Generally Accepted Accounting Principles (GAAP), Exelixis presents non-GAAP net income (and the related per share measures), which excludes from GAAP net income (and the related per share measures) stock-based compensation, adjusted for the related income tax effect for all periods presented.

Exelixis believes that the presentation of these non-GAAP financial measures provides useful supplementary information to, and facilitates additional analysis by, investors. In particular, Exelixis believes that these non-GAAP financial measures, when considered together with its financial information prepared in accordance with GAAP, can enhance investors’ and analysts’ ability to meaningfully compare Exelixis’ results from period to period, and to identify operating trends in Exelixis’ business. Exelixis has excluded stock-based compensation, adjusted for the related income tax effect, because it is a non-cash item that may vary significantly from period to period as a result of changes not directly or immediately related to the operational performance for the periods presented. Exelixis also regularly uses these non-GAAP financial measures internally to understand, manage and evaluate its business and to make operating decisions.

These non-GAAP financial measures are in addition to, not a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP. Exelixis encourages investors to carefully consider its results under GAAP, as well as its supplemental non-GAAP financial information and the reconciliation between these presentations, to more fully understand Exelixis’ business. Reconciliations between GAAP and non-GAAP results are presented in the tables of this release.

Second Quarter 2025 Highlights

Cabozantinib Franchise Net Product Revenues and Royalties. Net product revenues generated by the cabozantinib franchise in the U.S. were $520.0 million during the second quarter of 2025, with net product revenues of $517.9 million from CABOMETYX (cabozantinib) and $2.1 million from COMETRIQ (cabozantinib). Based upon cabozantinib-related net product revenues generated by Exelixis’ collaboration partners during the quarter ended June 30, 2025, Exelixis earned $43.4 million in royalty revenues.

Partner Ipsen Received Approval from the European Commission (EC) for CABOMETYX for Patients with Previously Treated Advanced NET. In July, Exelixis announced that its partner Ipsen received approval from the EC for CABOMETYX for adult patients with unresectable or metastatic, well-differentiated pancreatic (pNET) and extra-pancreatic (epNET) neuroendocrine tumors who have progressed following at least one prior systemic therapy other than somatostatin analogues. This approval follows the positive opinion received from the European Medicines Agency’s Committee for Medicinal Products for Human Use in June 2025 and allows for the marketing of CABOMETYX in this indication in all 27 member states of the European Union (EU), Norway, Liechtenstein and Iceland. In March, Exelixis received approval from the U.S. Food and Drug Administration (FDA) for CABOMETYX in this setting. These approvals were based on the positive results of the phase 3 CABINET pivotal trial, which evaluated CABOMETYX compared with placebo in two cohorts of patients with previously treated NET: advanced pNET and advanced epNET.

Announcement of Positive Top-line Results from the Phase 3 STELLAR-303 Pivotal Trial Evaluating Zanzalintinib in Combination with an Immune Checkpoint Inhibitor in Patients with Metastatic Colorectal Cancer (CRC). In June, Exelixis announced positive top-line results from the phase 3 STELLAR-303 pivotal trial in which the combination of zanzalintinib with atezolizumab (Tecentriq) demonstrated a statistically significant improvement in overall survival (OS) versus regorafenib in the intent-to-treat (ITT) population. The STELLAR-303 study is evaluating zanzalintinib in combination with atezolizumab versus regorafenib in patients with metastatic, refractory non-microsatellite instability-high or non-mismatch repair-deficient (non-MSI-H/dMMR) CRC. The ITT population consisted of all randomized patients, regardless of the presence of liver metastases. The top-line findings were from the final analysis conducted by the Independent Data Monitoring Committee of one of the dual primary endpoints of the STELLAR-303 phase 3 trial. The trial will proceed to the planned final analysis for the other dual primary endpoint of OS in patients without liver metastases (non-liver metastases or NLM). The NLM subgroup consisted of patients who did not have active liver metastases at baseline as determined by investigator assessment. Exelixis plans to discuss these results with regulators with the intention of filing for approval in this indication as soon as possible. Detailed results will be presented at a future medical meeting.

Presentation of Encouraging Results from Phase 1b/2 STELLAR-002 Trial Evaluating Zanzalintinib in Combination with Immune Checkpoint Inhibitors in Advanced Kidney Cancer at the 2025 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting (ASCO 2025). In June, Exelixis presented results from multiple dose-escalation cohorts of patients with advanced solid tumors, and an expansion cohort of patients with previously untreated advanced clear cell renal cell carcinoma (ccRCC) from the phase 1b/2 STELLAR-002 trial evaluating zanzalintinib in combination with either nivolumab (Opdivo) or a fixed-dose combination of nivolumab and relatlimab (Opdualag) at ASCO (Free ASCO Whitepaper) 2025. The results from the ccRCC expansion cohort demonstrated encouraging activity across all efficacy parameters, including objective response rate (ORR), progression-free survival (PFS) and disease control rates. The findings from the dose-escalation cohorts showed that the toxicity profile of these combinations was manageable and consistent with each agent administered as monotherapy.

Zanzalintinib Pivotal Development Program Updates. Today, Exelixis announced several updates to the zanzalintinib development program, including:

STELLAR-304 study enrollment completed in May 2025. STELLAR-304 is a phase 3 pivotal trial evaluating zanzalintinib in combination with nivolumab versus sunitinib in previously untreated patients with advanced non-clear cell renal cell carcinoma (nccRCC). The primary endpoints in the trial are PFS and ORR. Top-line results are expected in the first half of 2026, depending on study event rates.
Based on the company’s evaluation of emerging data from the phase 2 portion of the STELLAR-305 trial in advanced squamous cell carcinoma of the head and neck (SCCHN), emerging competition in this indication, and assessment of other, potentially larger, commercial opportunities, Exelixis has decided not to proceed to phase 3.
Initiation of the STELLAR-311 phase 3 pivotal trial in advanced NET. STELLAR-311 is evaluating zanzalintinib versus everolimus as a first oral therapy in patients with advanced NET, regardless of site of origin. The primary endpoint of the trial is PFS per Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 as assessed by Blinded Independent Central Review.
Plans to announce the next wave of zanzalintinib pivotal trials in the coming months.
Preclinical Data Presentations from Four Pipeline Programs in Advanced Cancers at the American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting (AACR 2025). In April, Exelixis presented preclinical data from four pipeline molecules at AACR (Free AACR Whitepaper) 2025. Presentations included data for XL309 and XL495, small molecules that have demonstrated synthetic lethality in the context of certain genetic anomalies found in varying frequencies across a broad array of tumor types. The XL309 findings demonstrated activity of XL309 as monotherapy or in combination with PARP or topoisomerase inhibitors. Data analysis from the XL495 program demonstrated the potential for anti-tumor activity both as monotherapy and in combination with DNA-damaging agents. However, based on early clinical data generated for XL495, Exelixis has discontinued further development of this program. Preclinical data were also presented for the PD-L1 + NKG2A-targeting bispecific antibody XB628 and for the tissue factor (TF)-targeting antibody-drug conjugate (ADC) XB371. Data analysis from the XB628 program demonstrated the molecule’s tumor cell killing activity both in vitro and in vivo, supporting advancement of this molecule into clinical development. Findings from XB371 non-clinical experiments demonstrated potent anti-tumor activity in vivo across a range of human tumor xenograft models including colorectal, lung, and pancreatic cancers, supporting the molecule’s advancement into phase 1 clinical development.

Advancement of XB628 and XB371 Pipeline Programs into Clinical Development. Today, Exelixis provided an update on the recent progress of its early-stage pipeline programs, including XB628 (PD-L1 + NKG2A-targeting bispecific antibody) and XB371 (TF-targeting ADC). In April, Exelixis initiated the phase 1 study of XB628, following the U.S. FDA clearance of its Investigational New Drug (IND) application in March. Exelixis now has three ongoing phase 1 trials for its pipeline programs XL309, XB010 and XB628. Additionally, in July, the U.S. FDA cleared Exelixis’ IND application for XB371 and the company plans to initiate the phase 1 study in the coming months.

Federal Income Tax Impact from the One Big Beautiful Bill Act. On July 4, 2025, the One Big Beautiful Bill Act was signed into law which, among other provisions, permanently repeals the requirement to capitalize domestic research and experimental (R&E) expenditures for federal income tax purposes for taxable years beginning after December 31, 2024, and allows for the accelerated deduction of any remaining unamortized domestic R&E expenditures. Foreign R&E expenditures are still required to be capitalized and amortized ratably over 15 years. Exelixis estimates its federal cash tax benefit for previously unamortized domestic R&E expenditures is $147 million with no corresponding impact to the federal income tax provision.

Positive Developments Across Cabozantinib Patent Estate. Today, Exelixis announced recent positive developments with regards to the company’s defense of its cabozantinib patent estate. First, in June and July 2025, the United States Patent and Trademark Office (USPTO) declined to institute Azurity Pharmaceuticals’ petitions for inter partes review (IPRs) of U.S. Patent Nos. 11,298,349 and 12,128,039, respectively. Second, in July 2025, Exelixis entered into a settlement agreement with Biocon Pharma Limited, which resolved the patent litigation Exelixis brought in response to Biocon’s Abbreviated New Drug Application (ANDA) seeking approval to market a generic version of CABOMETYX prior to the expiration of the applicable patents. Pursuant to the terms of the agreement, Exelixis will grant Biocon a license to market its generic version of CABOMETYX in the U.S. beginning on January 1, 2031, if approved by the FDA and subject to conditions and exceptions common to agreements of this type.

Stock Repurchase Program. In August 2024, Exelixis’ Board of Directors authorized a stock repurchase program to acquire up to $500 million of the company’s common stock before December 31, 2025. In February 2025, the Board of Directors authorized the repurchase of up to an additional $500 million of the company’s common stock before December 31, 2025. Under these programs, as of June 30, 2025, Exelixis has repurchased $796.3 million of the company’s common stock, at an average price of $36.69 per share. Since the approval of the first stock repurchase program in March 2023, the weighted-average diluted common shares outstanding has decreased from 326.3 million shares to 284.4 million shares as of June 30, 2025. Stock repurchases under these programs may be made from time to time through a variety of methods, which may include open market purchases, in block trades, accelerated share repurchase transactions, exchange transactions, or any combination of such methods. The timing and amount of any stock repurchases under the stock repurchase programs will be based on a variety of factors, including ongoing assessments of the capital needs of the business, alternative investment opportunities, the market price of our common stock and general market conditions.

Basis of Presentation

Exelixis has adopted a 52- or 53-week fiscal year that generally ends on the Friday closest to December 31. For convenience, references in this press release as of and for the fiscal periods ended July 4, 2025 and June 28, 2024, are indicated as being as of and for the periods ended June 30, 2025 and June 30, 2024.

The offer price per new fully paid ordinary share issued under the Placement ("New Share") was $4.20 ("Offer Price"), representing a 2.2% premium to Clarity’s last closing price and an 18.0% premium to the 15-day VWAP. Following the completion of the Placement, the Company will have a pro-forma cash balance of approximately $288 million1, which will help fund Clarity in connection with the below-mentioned expected catalysts and milestones, including the specified clinical trial programs.

Clarity’s Executive Chairperson, Dr Alan Taylor, commented, "The last eight months have been an incredibly tumultuous period for global markets generally, driven by the US political environment. When these times occur, pre-revenue biotechnology companies can be affected significantly more than other businesses due to their need to raise capital in order to get products to market. In addition to the global financial turmoil, there has been some unfortunate news from local biotechnology companies, putting significant pressure on the Australian biotechnology market. Being a successful pre-revenue biotechnology company listed on the ASX also presents additional considerations. For Clarity in particular, the inclusion of the Company in a number of indices over this period, such as the ASX200 and ASX300, has significantly raised the profile of the Company to certain investor groups, including index funds. These factors, amongst other variables, have contributed to the volatility in Clarity’s share price and an increasing number of short positions in our Company, reaching approximately 10% of our current total number of shares on issue.

"However, during this period of volatility our team has not lost sight of our purpose: to better the lives of people living with cancer. This drive has resulted in the achievement of many substantial milestones across our entire business, including outstanding clinical trial data, validation of new products in pre-clinical development, roll-out of enhanced supply and manufacturing in preparation for potential commercialisation and a number of important regulatory objectives.

"The coalescing of strong company fundamentals with ASX investor dynamics provided Clarity with an opportunity to capitalise with a fast, well-executed and sizeable placement to a small number of institutional investors who are close to the Company. The Placement has received phenomenal support, evidenced by the raising of over $200 million at not only a premium to the last closing share price, but a substantial premium to the share price observed for almost the entirety of CY2025. This places Clarity in a strong position, with an enviable Balance Sheet, where we can work to complete a number of high value-driving clinical trials, including our pivotal Phase 3 trials, as we progress our products towards potential commercialisation. The completion of the institutional Placement, coupled with significant short- and medium-term deliverables, such as the read-outs of the Co-PSMA trial and the Phase 3 trials, respectively, as well as longer-term activities, such as the further development of our therapy programs, are expected to underpin short-, medium- and longer-term shareholder value growth as we work towards our ultimate goal of better treating people with cancer."

Bell Potter Securities Limited acted as Sole Lead Manager. Lander & Rogers acted as Clarity’s Australian legal adviser.

Under the terms of the agreement, CFIP CLYD (UK) Limited ("Fortress") will subscribe to a capital increase for an aggregate amount of €1 million in exchange for 3,333,333 newly issued ordinary shares of Celyad. The shares will be issued at a subscription price of EUR 0.30 per share, which represents a 15% discount to the volume-weighted average price (VWAP) of Celyad’s shares on Euronext Brussels over the ten (10) trading days preceding the date of signing. Fortress’s subscription commitment is subject to customary conditions precedent. The closing is expected to take place on or around August 5, 2025. CFIP CLYD (UK) Limited is an affiliate of Fortress Investment Group.

The private placement is being conducted within the limits of the Company’s authorized capital as approved by the Extraordinary Shareholders’ Meeting of 14 November 2023, with cancellation of the preferential subscription rights of the existing shareholders in favor of Fortress. Following and subject to the issue of the shares to Fortress, Fortress is expected to hold approximately 58.51% of the Company’s shares.

The net proceeds of the placement will be used to support the working capital of the Company for general corporate purposes. The Company believes that following the close of the private placement, its cash runway will be extended from mid Q3 2025 to mid Q4 2025 which will give additional time for the Company to evaluate its strategic options to strengthen its balance sheet.

As Fortress qualifies as a related party of the Company, the board of directors applied Article 7:97 of the Belgian Code of Companies and Associations (the "BCCA"), which requires, among other things, the intervention of a committee of independent directors to give an opinion to the board of directors. The conclusions of the committee’s opinion is as follows: "The Committee has assessed the envisaged Transaction in light of the criteria included in article 7:97 of the BCCA and concluded, in view of the Company’s financial situation and cash flow requirements, after considering and examining alternative funding options and taking into account the interest of all stakeholders, that the expected advantages of the Transaction outweigh the expected disadvantages thereof, which leads to the conclusion that the Transaction is to the advantage and in the interest of the Company. The Transaction is in line with the Company’s strategic policy and is not manifestly unreasonable and the Committee affirms its positive advice in relation to the Transaction". The directors previously appointed by Fortress did not participate in the deliberations or votes.

In light of the Company’s limited cash runway, the board of directors believes that the envisaged capital increase is in the best interests of the Company and its stakeholders because, if completed, the capital increase will give additional time for the Company to evaluate its strategic options to strengthen its balance sheet. In accordance with article 7:97 of the BCCA, the Company’s auditor has issued a report on the accounting and financial information contained in the committee’s opinion and the board minutes approving the related party transaction. The auditor’s conclusion in this respect is as follows: "Based on our assessment, nothing has come to our attention that causes us to believe that the accounting and financial information included in the advice of the committee of independent directors dated July 23, 2025 and in the minutes of the Board of Directors dated July 23, 2025, justifying the proposed transaction, is not fair and sufficient, in all material respects, with regard to the information available to us within the scope of our mission."

On July 28, 2025 Celcuity Inc. (Nasdaq: CELC), a clinical-stage biotechnology company pursuing development of targeted therapies for oncology, reported positive topline results from the PIK3CA wild-type cohort of the Phase 3 VIKTORIA-1 clinical trial evaluating gedatolisib plus fulvestrant with and without palbociclib versus fulvestrant in adults with hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative, PIK3CA wild-type, locally advanced or metastatic breast cancer, following progression on, or after, treatment with a CDK4/6 inhibitor and an aromatase inhibitor (Press release, Celcuity, JUL 28, 2025, View Source [SID1234654569]).

In the trial, the gedatolisib triplet demonstrated a statistically significant and clinically meaningful improvement in PFS among patients, reducing the risk of disease progression or death by 76% compared to fulvestrant (based on a hazard ratio [HR] of 0.24, 95% confidence interval [CI] 0.17-0.35; p<0.0001). The mPFS, as assessed by blinded independent central review ("BICR"), was 9.3 months with the gedatolisib triplet versus 2.0 months with fulvestrant, an incremental improvement of 7.3 months.

The gedatolisib doublet also demonstrated a statistically significant and clinically meaningful improvement in PFS among patients, reducing the risk of disease progression or death by 67% compared to fulvestrant (HR of 0.33, 95% CI 0.24-0.48; p<0.0001). The mPFS, as assessed by BICR, was 7.4 months with the gedatolisib doublet versus 2.0 months with fulvestrant, an incremental improvement of 5.4 months.

The topline efficacy data from the VIKTORIA-1 PIK3CA wild-type cohort established several new milestones in the history of drug development for HR+/HER2- advanced breast cancer:

· The hazard ratios for the gedatolisib triplet and doublet are more favorable than have ever been reported by any Phase 3 trial for patients with HR+/HER2- ABC.

· The 7.3- and 5.4-months incremental improvements in median PFS for the gedatolisib triplet and gedatolisib doublet over fulvestrant, respectively, are higher than have ever been reported by any Phase 3 trial for patients with HR+/HER2- ABC receiving at least their second line of therapy.

· Gedatolisib is the first inhibitor targeting the PI3K/AKT/mTOR pathway to demonstrate positive Phase 3 results in patients with HR+/HER2-/PIK3CA wild-type ABC whose disease progressed on or after treatment with a CDK4/6 inhibitor.

Sara Hurvitz, MD, Senior Vice President, Clinical Research Division, Fred Hutchinson Cancer Center, Professor and Head, Division of Hematology and Oncology, University of Washington, Department of Medicine and co-principal investigator for the trial said: "Patients with HR-positive, HER2-negative, PIK3CA wild-type advanced breast cancer whose disease has progressed while on, or after, treatment with a CDK4/6 inhibitor typically derive limited benefit from subsequent endocrine-based therapy. The topline data for both gedatolisib regimens from VIKTORIA-1 are potentially practice-changing. To my knowledge, we have not seen Phase 3 results in patients with HR-positive, HER2-negative advanced breast cancer before where there was a quadrupling of the likelihood of survival without disease progression relative to the study control."

Treatment discontinuation due to a treatment-related adverse event for the gedatolisib triplet and gedatolisib doublet was lower than was observed in Arm D of the Phase 1b trial in patients with ABC, and lower than observed in any Phase 3 trials for currently approved drug combinations in HR+/HER2- ABC. Additionally, the gedatolisib triplet and gedatolisib doublet were better tolerated than was observed in the Phase 1b trial in patients with ABC, including lower rates of hyperglycemia and stomatitis.

Igor Gorbatchevsky, MD, Chief Medical Officer of Celcuity said: "The topline data from VIKTORIA-1 demonstrate the potential for gedatolisib to become a transformative new medicine for the treatment of patients with HR-positive, HER2-negative, PIK3CA wild-type advanced breast cancer whose disease progressed on or after treatment with CDK4/6 inhibitors. The 7.3 and 5.4-months incremental improvement in median PFS relative to fulvestrant for the gedatolisib regimens are potentially paradigm shifting results. We are also very excited that treatment with gedatolisib combined with fulvestrant with or without palbociclib was well-tolerated by the VIKTORIA-1 patients and that only a few patients discontinued treatment due to an adverse event."

Brian Sullivan, Chairman, Chief Executive Officer and co-founder of Celcuity said, "The efficacy improvement relative to the control that each of the gedatolisib regimens demonstrated was historic for this patient population. We are excited about the potential opportunity to provide a breakthrough therapeutic option for patients with HR-positive, HER2-negative, PIK3CA wild-type advanced breast cancer."

Full data from the PIK3CA wild-type cohort of the VIKTORIA-1 clinical trial will be presented at an upcoming medical conference later this year. Celcuity expects to submit a New Drug Application for gedatolisib to the U.S. Food and Drug Administration in the fourth quarter of 2025. Topline data for the VIKTORIA-1 PIK3CA mutation cohort is expected by the end of 2025.

Notes

HR+/HER2- Breast cancer

Breast cancer is the second most common cancer and one of the leading causes of cancer-related deaths worldwide.1 More than two million breast cancer cases were diagnosed globally in 2022.1 While survival rates are high for those diagnosed with early breast cancer, only approximately 30% of patients who are diagnosed with or who progress to metastatic disease are expected to live five years after their diagnosis.2 HR+/HER2- breast cancer is the most common subtype of breast cancer, accounting for approximately 70% of all breast cancers.2

Three interconnected signaling pathways, estrogen, cyclin D1-CDK4/6, and PI3K/AKT/mTOR (PAM), are primary oncogenic drivers of HR+, HER2- breast cancer.3 Therapies inhibiting these pathways are approved and used in various combinations for advanced breast cancer. Currently approved inhibitors of the PAM pathway for breast cancer target a single PAM pathway component, such as PI3Kα, AKT, or mTORC1.4,5,6,7 However, resistance to CDK4/6 inhibitors and current endocrine therapies develops in many patients with advanced disease.8 Survival rates are low with 30% of patients anticipated to live beyond five years after diagnosis.2 Optimizing the inhibition of the PAM pathway is an active area of focus for breast cancer research.

VIKTORIA-1

VIKTORIA-1 is a Phase 3 open-label, randomized clinical trial to evaluate the efficacy and safety of gedatolisib in combination with fulvestrant with or without palbociclib in adults with HR+/HER2- ABC whose disease progressed on or after prior CDK4/6 therapy in combination with an aromatase inhibitor. The clinical trial is enrolling subjects regardless of PIK3CA status while enabling separate evaluation of subjects according to their PIK3CA status. Subjects who meet eligibility criteria and do not have confirmed PI3KCA mutations (WT) were randomly assigned (1:1:1) to receive a regimen of either gedatolisib, palbociclib, and fulvestrant, gedatolisib and fulvestrant, or fulvestrant. Subjects who meet eligibility criteria and have confirmed PI3KCA mutations (MT) are randomly assigned (3:3:1) to receive a regimen of either the gedatolisib triplet, alpelisib and fulvestrant, or the gedatolisib doublet.

Gedatolisib

Gedatolisib is an investigational, multi-target PAM inhibitor that potently targets all four class I PI3K isoforms, mTORC1, and mTORC2 to induce comprehensive blockade of the PAM pathway.9,10,11 As a multi-target PAM inhibitor, gedatolisib’s mechanism of action is highly differentiated from currently approved single-target inhibitors of the PAM pathway.11 Inhibition of only a single PAM component gives tumors an escape mechanism through cross-activation of the uninhibited targets. Gedatolisib’s comprehensive PAM pathway inhibition ensures full suppression of PAM activity by eliminating adaptive resistance cross-activation that occurs with single-target inhibitors. Unlike single-target inhibitors of the PAM pathway, gedatolisib has demonstrated equal potency and comparable cytotoxicity in PIK3CA-mutant and -wild-type breast tumor cells in nonclinical studies and early clinical data.
