"The FDA’s clearance of our IND for PRT12396 marks a pivotal first milestone in the strategic transformation and development focus on our JAK2 and KAT6 programs that we outlined last quarter," stated Kris Vaddi, Chief Executive Officer of Prelude. "This achievement demonstrates our ability to translate high-quality science rapidly into clinical progress and our clear focus on executing these programs that represent the potential to reshape the treatment landscape for the target patient populations. We look forward to advancing PRT12396 into the phase 1 study in patients with polycythemia vera and myelofibrosis in parallel."

The Phase 1 study of PRT12396 is an open-label, multi-center, safety and efficacy study in patients with high-risk polycythemia vera (PV) and intermediate and high-risk myelofibrosis (MF). The primary endpoints of the study include safety, efficacy and PK profile.

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

Mutant selective JAK2V617F JH2 inhibitor program

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

"Approximately 40% of patients with HR+/HER2- advanced breast cancer harbor PIK3CA mutations, and most experience disease recurrence or progression following treatment with CDK4/6 inhibitors, leaving limited therapeutic options," said Don Bergstrom, M.D., Ph.D., President of R&D at Relay Therapeutics. "This Breakthrough Therapy designation underscores the FDA’s recognition of the potential of zovegalisib in combination with fulvestrant to meaningfully improve outcomes for these patients, reinforcing the impact of the encouraging clinical evidence we have demonstrated to date. We look forward to continuing to collaborate closely with the FDA as we work to advance this program as efficiently as possible for patients."

The FDA’s BTD is designed to accelerate the development and review of therapies for serious conditions when early clinical evidence suggests the potential for substantial improvement over available treatments. BTD provides eligibility for all Fast Track designation features, along with enhanced FDA guidance on development and increased engagement with senior FDA leadership.

BTD for zovegalisib was supported by clinical data generated to date from the Phase 1/2 ReDiscover trial, designed to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics and preliminary antitumor activity of zovegalisib in combination with fulvestrant, and in combination with fulvestrant and CDK inhibitors. Specifically, the application included data across all PIK3CA mutations (kinase and non-kinase) for two doses with comparable exposures: 600mg BID fasted (N=52) and 400mg BID fed (N=57), the dose being used in the ongoing Phase 3 trial, ReDiscover-2.

Safety and efficacy from the 600mg BID fasted data referenced above were presented at the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) 2025 Annual Meeting, with an additional efficacy subgroup analysis presented at the 2025 San Antonio Breast Cancer Symposium (SABCS).

Data for the 400mg BID fed (the Phase 3 dose) will be presented for the first time at ESMO (Free ESMO Whitepaper) Targeted Anticancer Congress 2026 on Monday, March 16.

About Zovegalisib

Zovegalisib is the lead program in Relay Therapeutics’ efforts to discover and develop mutant selective inhibitors of PI3Kα, the most frequently mutated kinase in all cancers and all vascular anomalies. Zovegalisib has the potential, if approved, to address a significant portion of the approximately 140,000 patients with HR+, HER2- breast cancer with a PI3Kα mutation per year in the United States and the estimated 170,000 patients with vascular anomalies driven by a PI3Kα mutation per year in the United States.

Traditionally, the development of PI3Kα inhibitors has focused on the active, or orthosteric, site. The therapeutic index of orthosteric inhibitors is limited by the lack of clinically meaningful selectivity for mutant versus wild-type (WT) PI3Kα and off-isoform activity. Toxicity related to inhibition of WT PI3Kα and other PI3K isoforms results in sub-optimal inhibition of mutant PI3Kα with reductions in dose intensity and frequent discontinuation. The Dynamo platform enabled the discovery of zovegalisib, the first known allosteric, pan-mutant, and isoform-selective PI3Kα inhibitor, designed to overcome these limitations. Relay Therapeutics solved the full-length cryo-EM structure of PI3Kα, performed computational long time-scale molecular dynamic simulations to elucidate conformational differences between WT and mutant PI3Kα, and leveraged these insights to support the design of zovegalisib. Zovegalisib is currently being evaluated in multiple metastatic breast cancer studies and a first-in-human study designed to treat patients with PIK3CA (PI3Kα) mutation driven vascular anomalies.

About PIK3CA-mutated, HR+/HER2- Advanced Breast Cancer

Hormone receptor-positive, human epidermal growth factor receptor 2-negative (HR+/HER2-) breast cancer is the most common subtype of breast cancer. Approximately 40% of patients with HR+/HER2- breast cancer harbor activating mutations in the PIK3CA gene, which drive tumor growth and are associated with poorer outcomes compared to patients without these mutations. Despite CDK4/6 inhibitors plus endocrine therapy being the standard of care in advanced disease, many patients with PIK3CA-mutated tumors have poorer outcomes and there are no approved regimens incorporating a pan-mutant selective PI3Kα inhibitor.

The Company’s Biologics License Application (BLA) resubmission for RP1 (vusolimogene oderparepvec) in anti-PD-1 failed melanoma was accepted by the FDA in October 2025 with a Prescription Drug User Fee Act (PDUFA) target action date of April 10, 2026. Commercial readiness activities are well underway to support a potential launch, if approved.

The Company has amended its existing loan agreement with Hercules Capital, Inc. The amendment included the draw down of $35 million upon closing and the potential to draw another $120 million at post approval milestones. The amendment also delays the repayment of debt from 2026 to 2027. The Company has extended its cash runway late into to the first quarter of 2027.

"We have been engaged with the FDA in the review of the BLA resubmission for RP1," said Sushil Patel, Ph.D., CEO of Replimune. "Advanced melanoma patients can progress quickly and are in urgent need of safe and effective treatment options. Our team remains ready to launch RP1 with commercial supply produced and the commercial organization prepared to engage with our target accounts rapidly, assuming FDA approval."

Program Highlights & Milestones

RP1 (vusolimogene oderparepvec)

IGNYTE-3 Confirmatory Study: The global Phase 3 trial will enroll approximately 400 patients and is assessing RP1 in combination with nivolumab versus physician’s choice in patients with advanced melanoma who have progressed on anti-PD-1 and anti-CTLA-4 therapies or are ineligible for anti-CTLA-4 treatment. The primary endpoint of this trial is overall survival, and key secondary endpoints are progression free survival and overall response rate.
Acral Melanoma: Recent data for RP1 plus nivolumab was recently presented at the ESMO (Free ESMO Whitepaper) Congress 2025. The analysis of acral melanoma data from the IGNYTE anti-PD-1 failed melanoma cohort showed treatment with RP1 combined with nivolumab resulted in an objective response rate (ORR) of 44% (8/18) with a median duration of response of 11.9 months. The safety profile was favorable with generally transient grade 1 and 2 treatment related adverse events.
Advanced Non-melanoma Skin Cancer (NMSC) Studies: Additionally, a poster from ESMO (Free ESMO Whitepaper) featuring data from the IGNYTE clinical trial showed that RP1 plus nivolumab provided responses across multiple advanced non-melanoma skin cancer (NMSC) tumor types, including anti–PD-1 naïve and failed disease, as well as both in locally advanced and metastatic disease. The ORR was 100.0%, 33.3%, 66.7%, and 56.3% in patients with anti–PD-1 naïve MCC, BCC, angiosarcoma, and CSCC, respectively. The ORR was 26.3%, 30.0%, 37.5%, and 15.2% in patients with anti–PD-1 failed MCC, BCC, angiosarcoma, and CSCC, respectively. The IGNYTE clinical trial cohort in NMSC is ongoing, however, enrollment was stopped in Q4 2025.
ARTACUS Study: Data from the ongoing ARTACUS Phase 2 trial evaluating the potential of RP1 as monotherapy in cutaneous squamous cell carcinoma patients following organ transplant were recently presented during an oral session at the Society for Melanoma Research 22nd International Congress. RP1 monotherapy showed robust anti-tumor activity in locally advanced CSCC with an ORR of 34.6% (CR rate was 23.1%) and 2-year duration of response of 61.0%. RP1 monotherapy was well tolerated, and the safety profile was similar to that observed in non-immunocompromised patients with advanced skin cancers.
RP2

REVEAL Study: The registration-directed Phase 2/3 trial of RP2 in metastatic uveal melanoma is actively enrolling. The trial is evaluating RP2 in combination with nivolumab versus ipilimumab in combination with nivolumab in approximately 280 patients. The primary endpoints of the trial are overall survival and progression free survival, and key secondary endpoints are overall response rate and disease control rate. Phase 2/3 transition is expected in Q1 2027, with PFS analysis potentially supporting accelerated approval.
Liver-focused Studies: The Phase 2 clinical trial of RP2 combined with atezolizumab and bevacizumab in anti-PD-1/PD-L1 progressed hepatocellular carcinoma is currently enrolling. The protocol was amended to include RP2 as monotherapy with data planned by the end of 2026. The trial is being conducted under a collaboration and supply agreement with Roche. The Company also has enrolled its first patients in a cohort evaluating RP2 in patients with biliary tract cancer. This cohort will evaluate RP2 combined with durvalumab.
Financial Highlights

Cash Position: As of December 31, 2025, cash, cash equivalents and short-term investments were $269.1 million, as compared to $483.8 million as of fiscal year ended March 31, 2025. The decrease in cash balance was a result of cash burn related to operating activities in advancing the company’s clinical development plans.

Based on the current operating plan, the Company believes that existing cash, cash equivalents and short-term investments will enable us to fund operations late into the first quarter of calendar 2027. This includes the potential commercialization of RP1 in skin cancers and for working capital and general corporate purposes and excludes any potential revenue.
R&D Expenses: Research and development expenses were $53.1 million for the fiscal third quarter and $48.0 million for the fiscal third quarter ended December 31, 2024. This increase was primarily due to an increase in RP1 direct research costs related to the IGNYTE-3 confirmatory study and other study costs including lab and operating supplies, as well as increased RP2 study costs. In addition, personnel-related costs increased as we continued to prepare for a potential commercial launch of RP1. Research and development expenses included $3.6 million in stock-based compensation expenses for the fiscal third quarter ended December 31, 2025.
S,G&A Expenses: Selling, general and administrative expenses were $18.7 million for the fiscal third quarter ended December 31, 2025, as compared to $18.0 million for the fiscal third quarter ended December 31, 2024. Selling, general and administrative expenses included $3.4 million in stock-based compensation expenses for the fiscal third quarter ended December 31, 2025.
Net Loss: Net loss was $70.9 million for the fiscal third quarter ended December 31, 2025 and $66.3 million for the fiscal third quarter ended December 31, 2024.
About RP1

RP1 (vusolimogene oderparepvec) is Replimune’s lead product candidate and is based on a proprietary strain of herpes simplex virus engineered and genetically armed with a fusogenic protein (GALV-GP R-) and GM-CSF intended to maximize tumor killing potency, the immunogenicity of tumor cell death, and the activation of a systemic anti-tumor immune response.

About RP2

RP2 is based on a proprietary strain of herpes simplex virus engineered and genetically armed with a fusogenic protein (GALV-GP R-) and GM-CSF intended to maximize tumor killing potency, the immunogenicity of tumor cell death and the activation of a systemic anti-tumor immune response. RP2 additionally expresses an anti-CTLA-4 antibody-like molecule, as well as GALV-GP R- and GM-CSF. RP2 is intended to provide targeted and potent delivery of these proteins to the sites of immune response initiation in the tumor and draining lymph nodes, with the goal of focusing systemic-immune-based efficacy on tumors and limiting off-target toxicity.

The Food and Drug Administration (FDA) grants Priority Review to applications for medicines that, if approved, would offer significant improvements over available treatment options by demonstrating safety or efficacy improvements, preventing serious conditions or enhancing patient compliance. The Prescription Drug User Fee Act date, the FDA action date for its regulatory decision, is anticipated during the second quarter of 2026.

The sBLA is being reviewed under Project Orbis, which provides a framework for concurrent submission and review of oncology medicines among participating international partners. This initiative is designed to bring effective cancer treatments to patients as early as possible.

Approximately 70% of patients with metastatic TNBC are not candidates for immunotherapy, including all patients whose tumours do not express PD-L1 as well as patients with PD-L1-expressing tumours who cannot receive immunotherapy due to other factors. Chemotherapy remains the only approved 1st-line treatment for these patients.1,2

Susan Galbraith, Executive Vice President, Oncology Haematology R&D, AstraZeneca, said: "Datroway is the only medicine to significantly improve overall survival compared to chemotherapy in this patient population as demonstrated in the TROPION-Breast02 trial – the results of which are even more striking considering the trial enrolled a subset of patients with highly aggressive disease. The Priority Review of our submission underscores the impact of these results and its review under Project Orbis signals a widely shared commitment to bringing Datroway to patients around the world as quickly as possible."

Ken Takeshita, Global Head, R&D, Daiichi Sankyo, said: "Datroway potentially could be the first medicine approved in the 1st-line setting to significantly extend overall survival and nearly double the time without disease progression or death compared to chemotherapy in patients with metastatic triple-negative breast cancer for whom immunotherapy was not an option. We are eager to work with the FDA to bring this much needed treatment option to patients with metastatic triple-negative breast cancer."

The sBLA is based on results from the TROPION-Breast02 Phase III trial which showed Datroway demonstrated a statistically significant and clinically meaningful 5.0-month improvement in median overall survival (hazard ratio [HR] 0.79; 95% confidence interval [CI] 0.64-0.98; p=0.0291) and a 43% reduction in patients’ risk of disease progression or death (HR 0.57; 95% CI 0.47-0.69; p<0.0001) compared to chemotherapy as 1st-line treatment in this patient population. Datroway was also associated with more robust and durable treatment responses, including an objective response rate (ORR) of 62.5% and duration of response (DoR) of 12.3 months, compared to an ORR of 29.3% and DoR of 7.1 months with chemotherapy. These results were presented at the 2025 European Society for Medical Oncology (ESMO) (Free ESMO Whitepaper) Congress.

The safety profile of Datroway in TROPION-Breast02 was consistent with previous clinical trials of Datroway in breast cancer.

Additional regulatory submissions for Datroway in breast and lung cancer are underway globally.

Datroway is a specifically engineered TROP2-directed DXd antibody drug conjugate (ADC) discovered by Daiichi Sankyo and being jointly developed and commercialised by AstraZeneca and Daiichi Sankyo.

Notes

Triple-negative breast cancer

TNBC accounts for approximately 15% of all breast cancer cases, with an estimated 345,000 diagnoses globally each year.3,4 In the US, an estimated 32,000 to 48,000 cases of TNBC were diagnosed in 2025.5,6 TNBC is diagnosed more frequently in younger and premenopausal women, and is more prevalent in Black and Hispanic women.7-9 Metastatic TNBC is the most aggressive type of breast cancer and has one of the worst prognoses, with median OS of just 12 to 18 months and only about 15% of patients living five years following diagnosis.7,10,11

While some breast cancers may test positive for oestrogen receptors, progesterone receptors or overexpression of HER2, TNBC tests negative for all three.7 Due to its aggressive nature and absence of common breast cancer receptors, TNBC is characteristically difficult to treat.7 For patients with metastatic disease with PD-L1 expressing tumours, the addition of immunotherapy to chemotherapy has improved outcomes in the 1st-line setting.12,13 However, for the approximately 70% of patients with metastatic TNBC who are not candidates for immunotherapy, chemotherapy remains the only approved 1st-line treatment.1,2

TROP2 is a protein broadly expressed in several solid tumours including TNBC.14 TROP2 is associated with increased tumour progression and poor survival in patients with breast cancer.15,16

TROPION-Breast02

TROPION-Breast02 is a global, multicentre, randomised, open-label Phase III trial evaluating the efficacy and safety of Datroway versus investigator’s choice of chemotherapy (paclitaxel, nab-paclitaxel, capecitabine, carboplatin or eribulin) in patients with previously untreated locally recurrent inoperable or metastatic TNBC for whom immunotherapy was not an option. This included patients whose tumours did not express PD-L1 as well as patients with PD-L1 expressing tumours who could not receive immunotherapy due to prior exposure in early-stage disease, comorbidities or immunotherapy not being accessible in their geography. Enrollment included patients with de novo or recurrent disease, regardless of disease-free interval, and those with poor prognostic factors such as stable brain metastases.

The dual primary endpoints of TROPION-Breast02 are PFS as assessed by blinded independent central review and OS. Secondary endpoints include PFS as assessed by investigator, ORR, DoR, disease control rate, pharmacokinetics and safety.

TROPION-Breast02 enrolled 644 patients at sites in Africa, Asia, Europe, North America and South America. For more information, visit ClinicalTrials.gov.

Datroway

Datroway (datopotamab deruxtecan; datopotamab deruxtecan-dlnk in the US only) is a TROP2-directed ADC. Designed using Daiichi Sankyo’s proprietary DXd ADC Technology, Datroway is one of six DXd ADCs in the oncology pipeline of Daiichi Sankyo, and one of the most advanced programmes in AstraZeneca’s ADC scientific platform. Datroway is comprised of a humanised anti-TROP2 IgG1 monoclonal antibody, developed in collaboration with Sapporo Medical University, attached to a number of topoisomerase I inhibitor payloads (an exatecan derivative, DXd) via tetrapeptide-based cleavable linkers.

Datroway is approved in more than 40 countries/regions worldwide for the treatment of adult patients with unresectable or metastatic HR-positive, HER2-negative (IHC 0, IHC 1+ or IHC 2+/ISH-) breast cancer who have received prior endocrine-based therapy and chemotherapy for unresectable or metastatic disease based on results from the TROPION-Breast01 trial.

Datroway is available in the US under accelerated approval for the treatment of adult patients with locally advanced or metastatic EGFR-mutated non-small cell lung cancer (NSCLC) who have received prior EGFR-directed therapy and platinum-based chemotherapy based on results from the TROPION-Lung05 and TROPION-Lung01 trials. Continued approval for this indication in the US may be contingent upon verification and description of clinical benefit in a confirmatory trial. Datroway is approved in Russia for the same population.

Datroway clinical development programme

A comprehensive global clinical development programme is underway with more than 20 trials evaluating the efficacy and safety of Datroway across multiple cancers, including NSCLC, TNBC and urothelial cancer. The programme includes eight Phase III trials in lung cancer, five Phase III trials in breast cancer and one Phase II/III trial in urothelial cancer evaluating Datroway as a monotherapy and in combination with other cancer treatments in various settings.

On February 3, 2026 Allarity Therapeutics, Inc. ("Allarity" or the "Company") (NASDAQ: ALLR), a Phase 2 clinical-stage pharmaceutical company dedicated to developing stenoparib (2X-121)—a differentiated, dual PARP and WNT pathway inhibitor, reported that enrollment is now open for its new Phase 2 clinical trial evaluating the combination of stenoparib and temozolomide for the treatment of recurrent small cell lung cancer (SCLC).

The trial is being conducted in collaboration with the U.S. Department of Veterans Affairs (VA) and is fully funded through the VA’s Special Emphasis Panel on Precision Oncology. The trial is officially registered as NCT06681220: Biomarker directed trial of temozolomide and stenoparib in relapsed SCLC and is now open for enrollment at 11 VA sites throughout the US.

This Phase 2 study will assess the safety and efficacy of stenoparib in combination with temozolomide, a DNA-alkylating chemotherapy agent, in patients with recurrent SCLC who have progressed after frontline treatment. Prior studies have shown that PARP inhibitors can enhance the activity of temozolomide, but widespread use has been limited by severe hematologic toxicity. The study includes a blood based biomarker developed in the VA Lung Precision Oncology Program to select patients most likely to benefit from this combination.

"The opening of recruitment marks an important step in exploring stenoparib’s potential as a combination agent," said Thomas Jensen, Chief Executive Officer of Allarity Therapeutics. "Based on clinical data to date from our ongoing trial in ovarian cancer, stenoparib has demonstrated a favorable safety profile, making it a strong candidate for combination therapies — particularly in settings where tolerability has been a limiting factor, as is the case in SCLC. More broadly, we believe stenoparib may offer meaningful clinical benefit in cancers where the WNT signaling pathway plays a key role, which applies to both SCLC and ovarian cancer. We’re particularly enthusiastic about taking this next step in stenoparib’s development as it allows us to explore stenoparib’s enormous potential in other indications and in combination with other agents."

Shadia Jalal, the study’s Principal Investigator and Professor of Medicine at the Lawrence H. Einhorn Chair in Oncology at Indiana University’s Melvin and Bren Comprehensive Cancer Center said, "We’re excited to explore this novel combination. Patients with relapsed SCLC including veterans have very few effective treatment options. Previous clinical work has shown that the combination of temozolomide with first generation PARP inhibitors is very active but also very limited by the toxicities of the two agents. Stenoparib has not only a unique mechanism of action that could provide benefit to these patients but also has a favorable safety profile that may allow veterans to tolerate this combination therapy and realize meaningful, durable clinical benefit."

While offering a potentially more favorable safety profile with temozolomide, stenoparib may offer additional anti-tumor benefit through suppression of WNT signaling, a pathway associated with SCLC progression and resistance.

In addition, stenoparib’s ability to cross the blood-brain barrier may offer therapeutic potential for patients with brain metastases, a common and challenging complication in advanced SCLC.

About Stenoparib/2X-121
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, Small Cell Lung Cancer and colorectal 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. Allarity has two ongoing Phase 2 trial protocols for stenoparib in Ovarian Cancer patients. In the first, patients who had had 2+ lines of therapy were enrolled on stenoparib and given drug twice daily. This protocol has been closed to further enrollment but continues for the enrolled patients who are still receiving benefit from stenoparib administration. The updated data from this study were presented at this AACR (Free AACR Whitepaper) special conference on advances in Ovarian Cancer. Note that, as these data are from an ongoing trial, analyses may change as the study fully matures. An amended protocol designed expressly to capitalize on the emerging clinical experience with stenoparib in platinum resistant patients began enrolling patients this summer. This amended protocol enrolls only platinum resistant or platinum-ineligible patients and is designed to accelerate the clinical development of stenoparib toward FDA approval.

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.
