The trial was not statistically powered to formally test overall survival (OS) however a descriptive analysis demonstrated no detriment.

More than 70% of bladder cancer patients are diagnosed with NMIBC, an early-stage cancer where the tumor is in the tissue that lines the inner surface of the bladder but has not invaded the muscle wall.1-2 About half of patients with NMIBC are classified as high-risk for disease progression or recurrence because of certain characteristics of their cancer, such as tumor grade, stage and specific tumor features.3

Maria De Santis, MD, Head of the Interdisciplinary Uro-Oncology Section at Charité Universitätsmedizin Berlin, Germany, and a principal investigator in the POTOMAC trial, said: "These exciting data show that adding one year of durvalumab to the current standard treatment significantly extends the time patients live without high-risk disease recurrence or progression. While most patients with non-muscle invasive bladder cancer are treated with curative intent, 80 percent see their disease return and almost half may require life-altering surgery to remove the bladder, underscoring the urgent need to improve treatment."

Cristian Massacesi, Chief Medical Officer and Oncology Chief Development Officer, AstraZeneca, said: "The positive results for IMFINZI in the POTOMAC trial represent a significant advance that will potentially allow more patients with early-stage bladder cancer to benefit from this important immunotherapy. Building on the NIAGARA data, this outcome demonstrates our strategy of bringing novel therapies to patients with early-stage disease where there is the greatest potential for long-term benefit."

The safety and tolerability of IMFINZI plus BCG induction and maintenance therapy was consistent with the known safety profiles of the individual medicines, with no new safety concerns identified. The addition of IMFINZI did not compromise patients’ ability to complete BCG induction and maintenance therapy.

The second experimental arm evaluating IMFINZI plus BCG induction-only therapy compared to BCG induction and maintenance therapy alone did not meet the endpoint of DFS.

These data will be presented at a forthcoming medical meeting and shared with global regulatory authorities.

IMFINZI is approved in the US and other countries for patients with muscle-invasive bladder cancer (MIBC) based on results from the NIAGARA Phase III trial and continues to be investigated across early and late-stage bladder cancer in various treatment combinations, including in patients with MIBC who are ineligible or refuse to take cisplatin (VOLGA) and in locally advanced or metastatic disease (NILE).

Severe and Fatal Immune-Mediated Adverse Reactions

Important immune-mediated adverse reactions listed under Warnings and Precautions may not include all possible severe and fatal immune-mediated reactions. Immune-mediated adverse reactions, which may be severe or fatal, can occur in any organ system or tissue. Immune-mediated adverse reactions can occur at any time after starting treatment or after discontinuation. Monitor patients closely for symptoms and signs that may be clinical manifestations of underlying immune-mediated adverse reactions. Evaluate clinical chemistries including liver enzymes, creatinine, adrenocorticotropic hormone (ACTH) level, and thyroid function at baseline and before each dose. In cases of suspected immune-mediated adverse reactions, initiate appropriate workup to exclude alternative etiologies, including infection. Institute medical management promptly, including specialty consultation as appropriate. Withhold or permanently discontinue IMFINZI and IMJUDO depending on severity. See USPI Dosing and Administration for specific details. In general, if IMFINZI and IMJUDO requires interruption or discontinuation, administer systemic corticosteroid therapy (1 mg to 2 mg/kg/day prednisone or equivalent) until improvement to Grade 1 or less. Upon improvement to Grade 1 or less, initiate corticosteroid taper and continue to taper over at least 1 month. Consider administration of other systemic immunosuppressants in patients whose immune-mediated adverse reactions are not controlled with corticosteroid therapy.

Notes

Bladder cancer

Bladder cancer is the 9th most common cancer in the world, with more than 614,000 cases diagnosed each year.4 The most common type is urothelial carcinoma, which begins in the urothelial cells of the urinary tract.2

In 2024, an estimated 125,000 patients were treated for high-risk NMIBC, for which the current standard of care is transurethral resection of bladder tumor (TURBT) followed by administration of BCG directly into the bladder.5-6 Up to 80% of patients experience disease recurrence within five years, and rates of progression in high-risk patients can be as high as 45%.2 There is a critical need for treatment options in this curative-intent setting.

POTOMAC

POTOMAC is a randomized, open-label, multi-center, global Phase III trial evaluating IMFINZI in combination with BCG therapy as a treatment for 1,018 patients with high-risk, BCG-naïve NMIBC who have undergone TURBT prior to randomization. Patients were randomized 1:1:1 to receive IMFINZI plus BCG induction and maintenance therapy, or IMFINZI plus BCG induction-only therapy, versus standard-of-care BCG induction and maintenance therapy.

The trial was conducted in more than 120 centers across 12 countries including Canada and others across Europe and Asia. The primary endpoint was DFS, defined as time from randomization to date of first recurrence of high-risk disease or death from any cause, for IMFINZI plus BCG induction and maintenance therapy compared to BCG induction and maintenance therapy alone. Secondary endpoints included DFS for IMFINZI plus BCG induction only therapy versus the comparator arm, as well as OS at five years and safety across both experimental arms of the trial.

IMFINZI

IMFINZI (durvalumab) is a human monoclonal antibody that binds to the PD-L1 protein and blocks the interaction of PD-L1 with the PD-1 and CD80 proteins, countering the tumor’s immune-evading tactics and releasing the inhibition of immune responses.

In addition to its indication in MIBC, IMFINZI is the global standard of care based on OS in the curative-intent setting of unresectable, Stage III non-small cell lung cancer (NSCLC) in patients whose disease has not progressed after chemoradiotherapy (CRT). Additionally, IMFINZI is approved as a perioperative treatment in combination with neoadjuvant chemotherapy in resectable NSCLC, and in combination with a short course of IMJUDO (tremelimumab-actl) and chemotherapy for the treatment of metastatic NSCLC. IMFINZI is also approved for limited-stage small cell lung cancer (SCLC) in patients whose disease has not progressed following concurrent platinum-based CRT; and in combination with chemotherapy for the treatment of extensive-stage SCLC.

IMFINZI is also approved in combination with chemotherapy in locally advanced or metastatic biliary tract cancer and in combination with IMJUDO in unresectable hepatocellular carcinoma (HCC). IMFINZI is also approved as a monotherapy in unresectable HCC in Japan and the European Union (EU).

In March 2025, perioperative IMFINZI added to standard-of-care chemotherapy met the primary endpoint of event-free survival in the MATTERHORN Phase III trial in resectable gastric and gastroesophageal junction cancers.

IMFINZI in combination with chemotherapy followed by IMFINZI monotherapy is approved as a 1st-line treatment for primary advanced or recurrent endometrial cancer (mismatch repair deficient disease only in US and EU). IMFINZI in combination with chemotherapy followed by olaparib and IMFINZI is approved for patients with mismatch repair proficient advanced or recurrent endometrial cancer in EU and Japan.

Since the first approval in May 2017, more than 374,000 patients have been treated with IMFINZI. As part of a broad development program, IMFINZI is being tested as a single treatment and in combinations with other anti-cancer treatments for patients with NSCLC, bladder cancer, breast cancer, ovarian cancer and several gastrointestinal cancers.

"The start of 2025 marks an important next chapter for Allarity," said Thomas Jensen, CEO of Allarity Therapeutics. "With enrollment about to begin in both our self-funded ovarian cancer trial and the Veterans Administration–funded combination trial in small cell lung cancer, we are focused on generating the data needed to advance stenoparib toward regulatory approval. The continued durability of response observed in ovarian cancer patients is encouraging, and we look forward to sharing updates on both trials in the months ahead."

Clinical and Drug Development Progress

Durable Clinical Benefit as monotherapy dosed twice daily: Multiple patients treated with stenoparib in the ongoing Phase 2 trial for advanced ovarian cancer exceeded 30 weeks on therapy, with two patients still on treatment and receiving benefit more than 19 months, underscoring the drug’s safety profile.
DRP Platform Expansion Beyond Small Molecules: At AACR (Free AACR Whitepaper) 2025, Allarity presented a novel DRP for daratumumab in multiple myeloma, marking the Company’s first DRP developed for a targeted antibody therapy. This milestone expands the versatility of the DRP platform, which was previously focused exclusively on small-molecule drugs.
New Protocol Implemented: Building on compelling data in the ongoing phase 2 ovarian cancer trial, the Company implemented a new Phase 2 protocol focused on platinum-resistant, advanced ovarian cancer patients, with the goal of optimizing dose and refining patient selection to accelerate stenoparib more aggressively toward regulatory approval.
Combination Trial Launched: Allarity announced a new Phase 2 trial evaluating stenoparib in combination with temozolomide for recurrent small cell lung cancer (SCLC), fully funded by the U.S. Veterans Administration. Allarity’s material contribution is limited to supplying the necessary stenoparib drug product. This novel trial is based upon compelling therapeutic rationale for the combination and could provide a new treatment option for these patients whose options are otherwise limited.
Clinical Data Presented at SGO: The Company presented updated Phase 2 clinical data at the Society of Gynecologic Oncology (SGO) 2025 Annual Meeting, demonstrating durable clinical benefit from stenoparib in heavily pre-treated ovarian cancer patients, including those with platinum-resistant, platinum-refractory, and BRCA wild-type disease.
Financial Strengthening and Corporate Development

Fully utilized the Company’s At-the-Market (ATM) offering program initiated in March 2024. With all capacity under the related Form S-3 now exhausted, the current ATM program has concluded.
Authorized a $5 million share repurchase program, reinforcing confidence in long-term shareholder value​.
To date, the Company has repurchased approximately 2 million shares under the authorized buyback program.
Initiated efforts to combat potential illegal short selling, engaging ShareIntel to investigate trading irregularities through enhanced market surveillance and potential legal action.
Ended Q1 2025 with a cash and restricted cash balance of approximately $27 million, further reinforcing the Company’s financial stability and ability to execute on clinical development objectives.
Regulatory and Compliance Resolutions

Finalized settlement with the SEC following receipt of a Wells Notice in July 2024, resolving all outstanding regulatory matters related to past disclosures by prior management regarding FDA interactions on the Dovitinib NDA, which was submitted to the FDA in 2021.
Had class action lawsuit dismissed, closing all related shareholder litigation and further clearing the path for Allarity to focus on clinical and corporate progress.
Anticipated Clinical Milestones in 2025

New Ovarian Cancer Trial Protocol—New Protocol Enrollment: In the first half of 2025, Allarity expects to begin enrollment under a new protocol for stenoparib in advanced, recurrent, platinum-resistant or platinum-ineligible ovarian cancer. The updated protocol design reflects the compelling, durable clinical benefit observed to date in platinum resistant patients. The protocol aims to provide the definitive foundation for pivotal registration trials for stenoparib in ovarian cancer.​
New Small Cell Lung Cancer Trial—Combination Study: Patient enrollment will initiate in Q2-Q3 2025 in this new Phase 2 trial evaluating stenoparib in combination with temozolomide for recurrent small cell lung cancer (SCLC). The trial, fully funded by the U.S. Veterans Administration, will assess the potential of this novel combination to improve outcomes in recurrent SCLC patients with extremely limited therapeutic opportunities.
First Quarter 2025 Operating Results

About Stenoparib
Stenoparib is an orally available, small-molecule dual-targeted inhibitor of PARP1/2 and tankyrase 1/2. At present, tankyrases are attracting significant attention as emerging therapeutic targets for cancer, principally due to their role in regulating the WNT signaling pathway. Aberrant Wnt/β-catenin signaling has been implicated in the development and progression of numerous cancers. By inhibiting PARP and blocking WNT pathway activation, stenoparib’s unique therapeutic action shows potential as a promising therapeutic for many cancer types, including ovarian cancer. Allarity has secured exclusive global rights for the development and commercialization of stenoparib, which was originally developed by Eisai Co. Ltd. and was formerly known under the names E7449 and 2X-121.

About the Drug Response Predictor – DRP Companion Diagnostic
Allarity uses its drug-specific DRP to select those patients who, by the gene expression signature of their cancer, may have a high likelihood of benefiting from a specific drug. By screening patients before treatment, and only treating those patients with a sufficiently high, drug-specific DRP score, the therapeutic benefit rate may be enhanced. The DRP method builds on the comparison of sensitive vs. resistant human cancer cell lines, including transcriptomic information from cell lines, combined with clinical tumor biology filters and prior clinical trial outcomes. DRP is based on messenger RNA expression profiles from patient biopsies. The DRP platform has shown an ability to provide a statistically significant prediction of the clinical outcome from drug treatment in cancer patients across dozens of clinical studies (both retrospective and prospective). The DRP platform, which may be useful in all cancer types and is patented for dozens of anti-cancer drugs, has been extensively published in the peer-reviewed literature.
