This early clinical activity was observed in a patient with PPP2R1A-mutated uterine serous carcinoma, a form of endometrial cancer, treated at the 150 mg dose level of APR-1051, with dose escalation continuing into higher dose cohorts to establish the recommended Phase 2 dose (RP2D). At the protocol-defined 8-week imaging assessment, the patient achieved a 50% reduction in target lesion size per RECIST v1.1 criteria, along with a marked reduction in cancer antigen 125 (CA-125) levels, from 732 to 70 U/mL, a well-recognized tumor marker in endometrial cancer.

In earlier cohorts of ACESOT-1051 study, multiple patients achieved stable disease with reductions in tumor burden, including a 5% reduction at the 70 mg dose in a patient with HPV-positive head and neck squamous cell carcinoma (HNSCC) and a 15% reduction in a patient with FBXW7-mutated colon cancer treated at the 100 mg dose. This patient has remained on therapy for over 210 days and is approaching their eighth treatment cycle. In addition, a second patient treated at the 150 mg dose level achieved stable disease at the first follow-up imaging assessment.

Collectively, these findings suggest that APR-1051 may have therapeutic potential across a range of solid tumors. Enrollment in the 220 mg dose level cohort of the study is currently underway, and the company intends to increase enrollment of HPV-positive patients in the ongoing trial.

"These early single-agent data demonstrate that APR-1051 has clinical activity as a single agent," said Anthony Tolcher, MD, FRCPC, Principal Investigator at Next Oncology. "The observation of a partial response on the first scan, together with a decrease in tumor marker at this dose level, supports continued clinical evaluation of APR-1051."

Oren Gilad, PhD, Chief Executive Officer of Aprea Therapeutics, added, "These preliminary results provide early proof-of-concept for single-agent activity of APR-1051 and support our strategy of targeting cancers with specific genomic alterations, including HPV-positive disease and PPP2R1A, FBXW7, CCNE1, TP53 and KRAS mutations. The potential dose-response trend and favorable safety profile observed in the ongoing dose-escalation study reinforce our confidence in the potential of APR-1051 as a differentiated WEE1 inhibitor for patients with advanced solid tumors. We look forward to providing additional updates in the first half of 2026 and completing dose escalation later in the year."

About the ACESOT-1051 Trial

ACESOT-1051 is a first-in-human, open-label Phase 1 study evaluating the safety, pharmacokinetics, pharmacodynamics, and preliminary efficacy of single-agent APR-1051 in patients with advanced solid tumors harboring cancer-associated genetic alterations. The dose-escalation portion of the study is expected to enroll up to 50 patients across nine planned dose cohorts, ranging from10 mg to 300 mg administered once daily. APR-1051 is administered orally once daily in continuous 28-day cycles. To date, enrollment has evaluated doses up to 150 mg, with the 220 mg cohort currently enrolling. For more information, refer to ClinicalTrials.gov ID NCT06260514.

EFTI DEVELOPMENT PROGRAM IN ONCOLOGY

IMMUTEP AND DR. REDDY’S STRATEGIC COLLABORATION

Most significantly, in December, Immutep and Dr. Reddy’s announced that their respective wholly-owned subsidiaries, Immutep SAS and Dr. Reddy’s Laboratories SA, entered into a strategic collaboration and exclusive licensing agreement for the development and commercialisation of eftilagimod alfa (efti) in all countries outside North America, Europe, Japan, and Greater China.

Efti is Immutep’s first-in-class novel immunotherapy that directly activates the immune system to fight cancer, which is under evaluation in a Phase III trial, TACTI-004 (KEYNOTE-F91).

As per the agreement, and after the quarter’s end, Immutep has received from Dr. Reddy’s the upfront payment of USD 20 million (~AUD 30.2 million). It is also eligible to receive potential regulatory development and commercial milestone payments of up to USD 349.5 million (~AUD 528.4 million), plus royalties on commercial sales in these markets.

Immutep holds the global manufacturing rights to the product across all markets and will supply the product to Dr. Reddy’s in the licensed markets. Immutep retains all rights to the product in the key pharmaceutical markets, including North America, Europe, and Japan.

LUNG CANCER

TACTI-004 (KEYNOTE-F91) – Ongoing Phase III Trial in 1L NSCLC

In December, Immutep reported strong operational progress in the TACTI-004 (KEYNOTE-F91) Phase III trial evaluating efti in combination with MSD’s (Merck & Co., Inc., Rahway, NJ, USA) anti-PD-1 therapy, KEYTRUDA (pembrolizumab), and chemotherapy as first line therapy for advanced/metastatic non-small cell lung cancer (1L NSCLC), one of the largest indications in oncology.

The combination of efti with KEYTRUDA and chemotherapy has the potential to establish a new standard of care in 1L NSCLC by expanding the number of patients who respond to anti-PD-1 therapy, across all PD-L1 expression levels, along with enhancing clinical outcomes and extending patients’ survival.

As of mid-December, the registrational TACTI-004 trial had enrolled 289 patients (over 38% of the trial’s targeted enrolment of 756 patients), and enrolment continues at a robust pace. Additionally, the number of activated clinical sites exceeded 120 and 27 countries had received full regulatory approvals.

As announced in October 2025, TACTI-004 had enrolled the necessary number of patients to conduct the futility analysis that remains on track for the first quarter of CY2026. Immutep anticipates reaching 50% of the patient enrolment target for TACTI-004 soon.

Additionally, with the completion of Project Optimus as discussed below, TACTI-004 has started to open sites in the United States.

INSIGHT-003 – Phase I Trial in Non-Squamous 1L NSCLC

In October, Immutep announced promising data from the investigator-initiated INSIGHT-003 trial, which is evaluating the same immunotherapy/chemotherapy combination used in TACTI-004 (KEYNOTE-F91), was detailed in a poster presented by Dr. med. Akin Atmaca, Head of the Thoracic Oncology, Krankenhaus Nordwest, UCT-University Cancer Center, Frankfurt, Germany at the ESMO (Free ESMO Whitepaper) Congress 2025.

In this multi-centre study, the novel combination of efti with KEYTRUDA and chemotherapy (carboplatin/pemetrexed) has generated strong objective response rates (ORR) and disease control rates (DCR) in 51 evaluable patients with advanced or metastatic non-squamous 1L NSCLC across all PD-L1 expression levels.

Notably, the ORR and DCR reported in INSIGHT-003 outperforms historical controls irrespective of PD-L1 levels (e.g., TPS <1%, TPS 1-49%, and TPS >50%). This is particularly important for patients with low and no PD-L1 (TPS <50%), who represent over two-thirds of the 1L NSCLC patient population and for whom PD-(L)1 inhibitors typically perform suboptimally. In patients with TPS <50% (N=47), the combination with efti has achieved a strong and improved 61.7% ORR compared to historical control of 40.8%.1,2

Further to the strong efficacy data from INSIGHT-003, the combination with efti continues to have a favourable safety profile.

SOFT TISSUE SARCOMA

EFTISARC-NEO – Phase II Trial in Soft Tissue Sarcoma

In October, Immutep announced that positive data from the EFTISARC-NEO Phase II investigator-initiated trial evaluating efti with radiotherapy plus KEYTRUDA in the neoadjuvant setting for resectable soft tissue sarcoma (STS) was shared in a Proffered Paper oral presentation by Katarzyna Kozak, M.D., Ph.D., Maria Sklodowska-Curie National Research Institute of Oncology, Warsaw, Poland at the ESMO (Free ESMO Whitepaper) Congress 2025 in Berlin, Germany.

The EFTISARC-NEO trial met the primary endpoint and significantly exceeded the study’s prespecified 35% tumour hyalinization/fibrosis with a median 51.5% tumour hyalinization/fibrosis (p<0.001) in the evaluable patient population (N=38).3 This may hold significance in terms of future outcomes as tumour hyalinization/fibrosis serves as an early surrogate endpoint correlated with improved survival in STS patients.4 Disease-free survival and overall survival data are immature at this stage and will be presented in the future.

In November, early translational data from the EFTISARC-NEO trial were detailed in an oral presentation by Paweł Sobczuk, M.D., Ph.D., Maria Sklodowska-Curie National Research Institute of Oncology, Warsaw, Poland, at the Connective Tissue Oncology Society (CTOS) 2025 Annual Meeting held in Boca Raton, Florida. Results from the initial twenty patients who underwent surgery in the trial show a strong immune system activation in line with efti’s mode of action, with statistically significant increases in the expression of key cytokines and chemokines in peripheral blood — specifically CXCL9, CXCL10, IL-23, and IFN-γ.

The increase on treatment of immune response biomarkers like IFN-γ correlated with pathologic responses in this study, meaning patients with a biomarker increase during treatment also had a higher probability of a good clinical response at surgery.

Additionally, during the quarter, the EFTISARC NEO trial was awarded second place in the distinguished Golden Scalpel Award competition in Poland. This competition recognises the most innovative solutions in Polish medicine and is presented by independent experts to initiatives that set new standards in advancing healthcare. EFTISARC-NEO was the only oncology project to receive this accolade, underscoring its leadership and breakthrough potential in cancer treatment.

BREAST CANCER

AIPAC-003 – Phase II/III Trial in Metastatic Breast Cancer

Immutep continues to execute the AIPAC-003 trial, which has enrolled 71 metastatic hormone receptor positive (HR+), HER2-negative/low patients resistant to endocrine therapy including cyclin-dependent kinase 4/6 (CDK4/6) inhibitors or triple-negative breast cancer patients.

Immutep completed patient enrolment in the randomised Phase II portion of the AIPAC-003 trial in late 2024. Patients across 22 clinical sites in Europe and the United States have been randomised 1:1 to receive either 30 mg or 90 mg dosing of efti in combination with paclitaxel to determine the optimal biological dose consistent with the FDA’s Project Optimus initiative and prior regulatory interaction with FDA.

In October, Immutep announced that positive feedback had been received from the US Food and Drug Administration ("FDA") regarding the successful completion of Project Optimus requirements and agreement on 30 mg as the optimal biological dose for efti. The agreement with the FDA on efti’s optimal biological dosing carries strategic importance in the ongoing and future clinical development of efti, including the global TACTI-004 (KEYNOTE-F91) Phase III trial.

In December, Immutep announced that new data from the AIPAC-003 trial was presented by Dr. Nuhad Ibrahim, Professor, Department of Breast Medical Oncology, Division of Cancer Medicine, The University of Texas MD Anderson Cancer Center at the 2025 San Antonio Breast Cancer Symposium (SABCS) taking place in San Antonio, Texas.

The data presented shows that both efti dosing levels on top of weekly paclitaxel in heavily pretreated metastatic breast cancer patients, who received a median of three prior lines of systemic therapy, led to strong objective response rates (ORR) and disease control rates (DCR) of 41.9% and 87.1% (30 mg efti) and 48.5% and 78.8% (90 mg efti), respectively, in the evaluable population (N=64).

New Investigator-Initiated Phase II Trial for Neoadjuvant Efti in HR+/HER2-negative Breast Cancer

Immutep continues to progress with a new investigator-initiated Phase II trial evaluating neoadjuvant efti as monotherapy and in combination with chemotherapy prior to surgery in early-stage HR+/HER2-negative breast cancer patients. The trial aims to assess pathological complete response (pCR) after neoadjuvant efti treatment and neoadjuvant chemotherapy (NAC).

The study will treat up to 50 evaluable patients in a two-stage design and will be primarily funded by grants and The GW University Cancer Center. Immutep will provide efti at no cost, technical support, and limited funding that falls within its existing budget.

UROTHELIAL CANCER

INSIGHT-005

The investigator-initiated INSIGHT-005 Phase I study, conducted by the Institute of Clinical Cancer Research, Krankenhaus Nordwest (IKF) to evaluate the safety and efficacy of efti in combination with avelumab in up to 30 patients with metastatic urothelial cancer, was discontinued by IKF after the end of the quarter. This decision was made, as significant changes in the treatment landscape created challenges with patient recruitment. Only 3 patients were recruited in total.

IMP761 DEVELOPMENT PROGRAM FOR AUTOIMMUNE DISEASE

IMP761 – Phase I Trial

In December, Immutep announced a positive update from the placebo-controlled, double-blind first-in-human Phase I study in healthy participants evaluating IMP761, a first-in-class LAG-3 agonist antibody for autoimmune diseases.

The single-ascending dose escalation portion of the trial successfully completed the 2.5 and 7 mg / kg dosing levels of IMP761 with continued positive safety and efficacy data. IMP761 was tolerated well with no treatment-related adverse reactions beyond mild intensity. Additionally, evidence of dose dependent immunosuppressive effects with IMP761 was observed with significant, long-lasting inhibition of the three T-cell-mediated intradermal reactions to a strong foreign antigen on day 2, 9 and 23.

Given the encouraging efficacy and safety to date, the trial will continue as planned and additional updates are anticipated in the first half of CY2026 including a planned presentation of data at a major medical conference.

INTELLECTUAL PROPERTY

During the quarter, Immutep was granted four patents.

The New Zealand Patent Office granted a new patent protecting Immutep’s intellectual property for a binding assay for determining MHC Class II binding activity of LAG-3 protein. The assay is used in the characterisation of efti in GMP-grade manufacturing.

Three new patents directed to IMP761 were also granted. Two were granted in Brazil and one in Japan.

CORPORATE & FINANCIAL SUMMARY

Annual General Meeting
Immutep successfully held its Annual General Meeting (AGM) during the quarter, with all resolutions put forward to shareholders strongly approved. The Company appreciates the continued support and engagement of its shareholders as it advances its strategic and operational objectives.

Cash Flow Summary

During the quarter, Immutep continued to exercise prudent cash management as it advanced its clinical trial programs for efti and for IMP761.

The Company is well funded with a strong cash and cash equivalent, and term deposit balance as at 31 December 2025 of approximately A$99.1 million, which is in line with budget as at the beginning of FY2026, while progressing our clinical programs within announced timeframes. The total balance consists of 1) a cash and cash equivalent balance of A$72.7 million and 2) bank term deposits totaling A$26.4 million, which have been recognised as short-term investments due to having maturities of more than 3 months and less than 12 months. This amount is topped up by the upfront payment (~A$30.2 million) from Dr. Reddy’s received in January 2026, leading to a pro-forma balance of A$129.3 million at the time of preparing this report.

In Q2 FY26, cash receipts from customers were A$4k. The net cash used in G&A activities in the quarter was A$1.3 million, compared to A$578k in Q1 FY26. During the quarter, Immutep received EUR2.59 million (~ A$4.6 million) R&D tax incentive payment in cash from the French Government under its Crédit d’Impôt Recherche scheme (CIR) to support the ongoing and planned global clinical development of efti and IMP761.

The cash used in R&D activities during the quarter was A$9.9 million, compared to A$15.8 million in Q1 FY26. The higher figure in the prior quarter was primarily due to the large prepaid clinical trial expenses and higher milestone‑based manufacturing payments made in Q1 FY26.

Payment for staff costs was A$2.6 million in the quarter, compared to A$3.4 million in Q1 FY26. Total net cash outflows used in operating activities in the quarter were A$9.4 million compared to A$19.0 million in Q1 FY26.

Payments to Related Parties comprises Non-Executive Directors’ fees and Executive Directors’ remuneration of A$474k.

Total cash outflow used in investing activities for the quarter was A$144k, which is mainly for the acquisition of office and lab equipment.

Furthermore, during the quarter, a long-term vendor* agreed to defer payment of ~A$30 million which would be payable by Immutep for future services related to Biologics License Application (BLA) readiness by up to 30 months. This provides strong external validation of Immutep’s development strategy and long-term value creation potential.

The current funds available to the Company at the time of this report provide an expected cash reach well into Q2 CY2027, not including receipt of any future potential milestone payments to be received.

The randomized part of the study has been actively recruiting patients at six sites since March 2025. Four additional sites have now been opened, and the first patient has been enrolled at one of these newly activated sites.

"The process of opening new clinical sites involves extensive regulatory reviews, contracting, and site-readiness work. We are therefore pleased to see both the successful activation of additional sites and the enrollment of the first patient at a newly onboarded site," said Kari Myren, Chief Medical Officer at Oncoinvent.

The Phase 2 trial (Clinicaltrial.gov: NCT06504147) is a randomized controlled trial assessing the efficacy and safety of Radspherin in patients with peritoneal metastases from ovarian cancer. The primary objective is to compare progression-free survival (PFS) between patients who receive Radspherin after complete surgical resection following pre-operative chemotherapy, and patients receiving pre-operative chemotherapy and surgery alone.

The study will recruit patients at a total of 11 sites across Norway (1), Spain (5), Belgium (1), the United Kingdom (2), the United States (1), and Italy (1). Positive Phase 1/2a data from the safety interim analysis demonstrated that Radspherin was well tolerated with no dose-limiting toxicity observed at the recommended dose of 7MBq.
