"I couldn’t be prouder to announce this proposed collaboration with the University of Wisconsin and the renowned team at their Department of Human Oncology. We share a mutual goal to expand the curative power of radiotherapy with technologies that not only help extend survivorship but also quality of life―and we believe OART can help to do just that. The proposed collaboration aims to leverage our respective strengths to reshape the overall OART experience for providers so that ultimately, clinical departments of all sizes can find it feasible to incorporate this advanced treatment option into their practice," said Mu Young Lee, SVP, Research & Product Development at Accuray.

University of Wisconsin–Madison researchers invented the first helical radiation delivery platform, the TomoTherapy System. It ushered in a new era in radiation medicine that enabled clinicians, for the first time, to leverage a system specifically designed for integrated 3D daily image-guidance with intensity-modulated radiation therapy (IG-IMRT) to increase the precision and accuracy of treatments and help better control patients’ cancer. Since the TomoTherapy System’s introduction, Accuray has continued to evolve the helical platform with the purpose of further enhancing its precision and accuracy, as well as introducing advances in the areas of image quality, speed, versatility, and workflow efficiencies.

"The origins of the TomoTherapy System began right here at UW–Madison, and our clinical researchers have deep experience in bringing future innovations from bench to bedside," said Nita Ahuja, MD, MBA, Dean of the school and Vice Chancellor for Medical Affairs at the University of Wisconsin–Madison. "This MOU focused on online adaptive radiotherapy for personalized, precision cancer care signifies our commitment to keeping patients at the center of our research efforts, while also allowing important translational medicine training opportunities for the next generation of clinical researchers and physician-scientists."

On September 30, 2025 AbbVie (NYSE: ABBV) reported submission of a new Biologics License Application (BLA) to the U.S. Food and Drug Administration (FDA) for approval of investigational Pivekimab sunirine (PVEK) for treatment of Blastic Plasmacytoid Dendritic Cell Neoplasm (BPDCN) (Press release, AbbVie, SEP 30, 2025, View Source;an-investigational-antibody-drug-conjugate-adc-to-treat-rare-cancer-with-limited-treatment-options-302570103.html [SID1234656356]). The submission is based on data from the Phase 1/2 CADENZA trial, a global study evaluating the safety and efficacy of PVEK in BPDCN. BPDCN is a rare and aggressive blood cancer that has features of both leukemia and lymphoma. Patients typically present with skin lesions and the disease often spreads to the bone marrow, central nervous system and the lymph nodes. First-line treatments are typically intensive chemotherapy and often followed by stem cell transplant. The need for additional and innovative treatment is high for both newly diagnosed patients and for those whose prior treatments have resulted in relapsed or refractory disease.

PVEK is a CD123-targeting Antibody-Drug Conjugate (ADC) in clinical development for hematological malignancies (blood cancers), including BPDCN and acute myeloid leukemia (AML). ADCs are designed to deliver potent cancer cell death-inducing agents called ‘payloads’ directly to the cancer cells expressing a specific protein. CD123 (IL-3Rα) is a protein overexpressed in BPDCN, making it an ideal target for therapy.

"Meaningful innovations in cancer research and treatment are happening every day. It is important that these innovations reach patients who desperately need them, including those with rare cancers who have limited options," said Roopal Thakkar, executive vice president, research and development and chief scientific officer, AbbVie. "We look forward to next steps in the regulatory process for our latest Antibody-Drug Conjugate (ADC), our first ADC in blood cancer, and how it may advance treatment for those living with Blastic Plasmacytoid Dendritic Cell Neoplasm (BPDCN)."

About the CADENZA Trial
CADENZA is a Phase 1/2 multicenter, open-label study designed to determine the maximum tolerated dose (MTD), recommended Phase 2 dose (RP2D), and recommended dosing schedule for PVEK monotherapy and to assess the safety, tolerability, PK, immunogenicity, and antileukemia activity of PVEK when administered to subjects with CD123+ hematologic malignancies (including subjects with BPDCN, AML, and others).

About Pivekimab Sunirine (PVEK)
PVEK is a CD123-targeting ADC in clinical development for hematological malignancies, including blastic plasmacytoid dendritic cell neoplasm (BPDCN) and acute myeloid leukemia (AML). PVEK is currently being evaluated as monotherapy for patients with BPDCN and in combination with Vidaza (azacitidine) and Venclexta (venetoclax) for patients with untreated and relapsed/refractory AML. In October 2020, the FDA granted PVEK Breakthrough Therapy designation in relapsed/refractory BPDCN.

The allowed claims protect the use of iadademstat in combination with PD1 or PD-L1 inhibitors for the treatment of cancer, including small cell lung cancer (SCLC). Once formally granted, the patent will remain in force until at least 2040, excluding potential patent term extensions. Corresponding patents have already been allowed or granted in Australia and Russia, with additional applications pending in the United States, Japan, China, and other territories.

"We are delighted to have secured this grant, which strengthens protection for iadademstat in combination with immune checkpoint inhibitors such as atezolizumab and durvalumab, a therapeutic approach we are actively pursuing in clinical trials", said Neus Virgili, Oryzon’s Chief IP Officer.

Iadademstat is currently being investigated in combination with PD-L1 inhibitors (atezolizumab or durvalumab) in first line, extensive-disease SCLC patients in a Phase I/II trial conducted and sponsored by the U.S. National Cancer Institute (NCI) under a Cooperative Research and Development Agreement (CRADA) with Oryzon. More than 30 sites accross the U.S. participate in the trial, including leading institutions such as Memorial Sloan Kettering Cancer Center, Johns Hopkins, City of Hope, Yale University and the University of Chicago, among others.
