The company also announced the submission of an IND for HWK-016, its MUC16-targeted ADC, to the FDA in December 2025. A Phase 1 trial is anticipated to start recruiting this quarter and is expected to initially evaluate activity in two high MUC16-expressing gynecologic cancers, ovarian and endometrial.

Both next-generation ADC programs leverage Whitehawk’s advanced ADC technology platform consisting of a highly stable yet cleavable linker that delivers a DNA Topoisomerase I (TOP1) inhibitor payload. Whitehawk expects to report initial clinical data from these trials in early 2027.

"These are important regulatory and execution milestones, underscoring the strength of our preclinical data and our ability to advance multiple programs in parallel," said Dave Lennon, PhD, President and CEO of Whitehawk Therapeutics. "At Whitehawk, we are taking a unique approach to the development of next-generation ADCs, combining validated tumor biology with a differentiated ADC architecture. Our platform’s design features are intended to maximize tumor targeting while minimizing off-target toxicity, enabled by highly selective antibodies, a stabilizing bioconjugation strategy that includes carbon-bridge cysteine re-pairing, and controlled delivery of a potent TOP1 inhibitor payload. As our lead programs enter the clinic, our focus will be on efficient clinical execution to generate data that validates this approach with meaningful outcomes for patients."

About HWK-007
HWK-007 is a differentiated next-generation ADC targeting Protein Tyrosine Kinase 7 (PTK7). PTK7 is an oncofetal transmembrane pseudokinase that drives early embryonic development, has restricted expression in adult tissues and frequent overexpression in a wide range of cancers. PTK7 is the third most highly expressed tumor marker among clinically validated and emerging ADC targets, present in ~70% of tumors. There are no approved PTK7-directed ADCs.

HWK-007-101 is a Phase 1, multicenter, open-label study in adult participants that will employ a sequential dose-escalation and expansion design to evaluate the safety, pharmacokinetics and preliminary antitumor activity of HWK-007 in participants with advanced or metastatic solid tumors that are refractory to standard therapies.

About HWK-016
HWK-016 is a differentiated next-generation ADC targeting the membrane-bound portion of Mucin 16 (MUC16). MUC16 is a glycoprotein with low level of expression in normal adult tissues, and broad overexpression in gynecological tumors including ovarian, cervical and endometrial. In ovarian cancer, for example, MUC16 is present at rates up to 3-10 times higher than clinically validated and emerging ADC targets.

Shed MUC16 (CA125) is a validated biomarker for cancer screening and disease monitoring in gynecologic cancers. When ADCs bind to this cleaved portion of the MUC16 protein in circulation, it is cleared from the patient systemically rather than reaching the tumor. HWK-016 is designed to overcome this by directly targeting the membrane-bound, non-shed portion of MUC16.

HWK-016-101 is a planned Phase 1, multicenter, open-label study in adult participants that will employ a sequential dose-escalation and expansion design to evaluate the safety, tolerability, pharmacokinetics and preliminary antitumor activity of HWK-016 in participants with advanced or metastatic solid tumors that are refractory to standard therapies.

The TEADES trial is a Phase 2 multi-center, open-label study that will enroll approximately 300 patients with MPM, EHE or other solid tumors with dysfunction in Hippo pathway. The trial will include patients who have progressed after receiving standard treatments and have no further treatment options. The primary endpoints of the study are safety and tolerability with secondary endpoints including Overall Response Rate, Progression Free Survival and Overall Survival. This is a global trial conducted at leading oncology centers in the US and Europe.

"Treating the first patient in this Phase 2 study represents an important milestone for ODM-212 clinical development program and more importantly for patients," said Praveen Aanur, MD, MPH, MBA, Chief Medical Officer, Oncology Therapy Area, Orion Pharma. "The encouraging Phase 1 results demonstrated clinical activity as monotherapy with manageable safety profile across different doses and schedules that were tested. We are also excited for the potential of combination treatments with ODM-212 given its mechanism to overcome resistance in standard therapies and emerging therapies in multiple tumor types. Building on the promising Phase 1 data, we are advancing ODM-212 with urgency and scientific rigor as monotherapy and combination therapy for patients across multiple cancers."

Orion is planning to publish results from the phase 1 part of TEADES trial in an upcoming scientific conference in 2026. Preliminary results in EHE patients were presented at the CTOS annual meeting held in Miami, US in November 2025.

About ODM-212
ODM-212 is an oral small-molecule pan-TEAD (Transcriptional Enhanced Associate Domain) inhibitor developed by Orion Pharma. It targets the Hippo signaling pathway, which regulates cell growth and organ size. Dysregulation of this pathway—particularly through YAP/TAZ activation—can lead to uncontrolled tumor growth and resistance to cancer therapies. ODM-212 works by blocking TEAD transcription factors, disrupting YAP-TEAD protein-protein interactions, and inhibiting TEAD auto-palmitoylation, which is essential for TEAD activity.

About Malignant Pleural Mesothelioma
Malignant Pleural Mesothelioma (MPM) is a rare and aggressive cancer that originates in the pleura—the thin membrane lining the lungs and chest wall. It accounts for about 80–90% of all mesothelioma cases and is strongly linked to asbestos exposure. Current treatments mainly include chemotherapy and immunotherapy.

About Epithelioid Hemangioendothelioma
Epithelioid Hemangioendothelioma (EHE) is an ultra-rare vascular tumor or abnormality that arises from the cells lining the blood vessels. It is estimated that less than one per million people are living with this rare cancer. Currently there is no standard treatment for EHE.

Highlights of FDA responses to the Company’s key enquiries:

Accelerated approval – FDA indicated that accelerated approval may be appropriate for the LM indication, but there are insufficient data to support the use of circulating tumor cells (CTCs) as an intermediate clinical endpoint. FDA and Plus discussed that additional steps would be necessary to validate CTCs as a surrogate endpoint to potentially support other future applications.
Primary and key endpoints – FDA recommended that the study evaluate an endpoint with established clinical benefit, such as overall survival, while encouraging further study of patient reported outcomes and neurologic function as endpoints that could potentially support a marketing application. FDA and Plus aligned that CTCs could be considered for use as a secondary endpoint.
Trial design and comparator group – FDA and Plus discussed a randomized controlled trial design approach and that the study may include an intrathecal chemotherapeutic as a comparator, as well as approaches to standardize the comparator and any additional interventions available under the trial protocol.
Treated populations – FDA conveyed it may be reasonable to incorporate multiple histologies (i.e., multiple underlying disease etiologies) in a single trial.
"Our recent FDA end of phase meeting was constructive, and we hope will help us speed up our clinical development timelines and facilitate faster submission of an application for the approval of REYOBIQ for patients with LM," said Dr. Marc H. Hedrick, President & Chief Executive of Plus Therapeutics. "As there are no approved drugs for LM, this discussion with the FDA early in clinical development will allow us to make relevant amendments to our current trial protocol and to begin meaningful planning for an anticipated pivotal trial. Furthermore, based in part on this meeting, we will plan to accelerate REYOBIQ commercial manufacturing and scale-up activities to meet an expedited timeline."

About LM
Leptomeningeal metastases (LM) are a rare but severe complication of advanced cancer, affecting the fluid-lined structures of the central nervous system. LM occurs in approximately 5% of patients with metastatic cancer, with breast cancer, lung cancer, and melanoma being the most common sources. Median survival is typically 2-6 months, and effective treatment options are limited, highlighting the urgent need for novel therapies.

Building on their existing collaboration, the companies have signed a new agreement to focus on lead optimization of drug candidates identified by Variational AI’s Enki generative AI platform and selected by Rakovina for further evaluation in the kt-5000 ATR inhibitor program. Under the expanded scope of work, Variational AI will apply its generative AI platform to iteratively optimize the initial leads with the goal of identifying a clinical candidate in months versus the industry standard of years.

Variational AI will generate and prioritize multiple optimized compound designs, while Rakovina will retain full control over which candidates to advance into laboratory testing and further development. The expanded collaboration is intended to accelerate the identification of high-quality development candidates while reducing the time and cost typically required in early-stage drug discovery.

Rakovina’s kt-5000 program comprises a series of small-molecule inhibitors targeting ATR (ataxia telangiectasia and Rad3-related), a central regulator of the DNA damage response that enables cancer cells to survive replication stress and DNA damage. ATR inhibition has emerged among big pharma companies as a promising therapeutic strategy in solid tumors, including cancers with DNA repair deficiencies such as ovarian, breast, and prostate cancer.

Rakovina recently reported results from the kt-5000 series, including compounds with dual ATR/mTOR activity and designed to achieve central nervous system (CNS) penetration at the Society for NeuroOncology annual meeting. These preclinical findings highlight efforts to address known limitations of existing ATR inhibitors and support continued optimization of the compounds.

"ATR is a proven oncology target, but real differentiation comes from optimizing the drug itself," said Jeffrey Bacha, executive chairman of Rakovina Therapeutics. "This expanded collaboration with Variational AI enables a highly focused, AI-driven refinement of kt-5000 compounds identified for further evaluation, with particular attention to potency, selectivity, and CNS penetration. The result is a more efficient path to identifying high-quality candidates while maintaining strategic flexibility for development and partnering."

"Our Enki generative AI platform efficiently explores novel chemical space and has already generated promising leads for Rakovina," said Handol Kim, Co-Founder and CEO of Variational AI. "With this expanded collaboration, we are now applying Enki to exploit these novel leads through local chemical search to efficiently perform lead optimization and enable Rakovina to get to human trials faster."
