"We are encouraged by this meaningful progress toward addressing the needs of patients with previously treated metastatic colorectal cancer, for whom effective therapies have been limited and treatment outcomes remain poor," said Dana T. Aftab, Ph.D., Executive Vice President, Research and Development, Exelixis. "Zanzalintinib has the potential to become an important advancement in a challenging treatment landscape, and if approved, zanzalintinib in combination with atezolizumab would provide a novel mechanism of action for patients with previously treated metastatic colorectal cancer. We are deeply grateful to the patients, caregivers and investigators contributing to the clinical research in support of this application, and we look forward to collaborating with the FDA during the review process for our first NDA for zanzalintinib."

The NDA is based on the results of the phase 3 STELLAR-303 pivotal trial, in which zanzalintinib in combination with atezolizumab demonstrated a statistically significant improvement in overall survival (OS) versus regorafenib in the intention-to-treat (ITT) population of patients with previously treated CRC. Detailed results, including OS and progression-free survival (PFS) in the ITT population and in the subset of patients without liver metastases (non-liver metastases, NLM), were presented at the 2025 European Society for Medical Oncology (ESMO) (Free ESMO Whitepaper) Congress and published in The Lancet. Data pertaining to the other dual primary endpoint, OS in patients without active liver metastases, were immature at the data cutoff, and the trial is proceeding to the planned final analysis for this endpoint, which is expected in mid-2026, based on current event rates.

About STELLAR-303
STELLAR-303 (NCT05425940) is a global, multicenter, randomized, phase 3, open-label study that randomized patients 1:1 to either zanzalintinib in combination with atezolizumab (n=451) or regorafenib (n=450). The study includes patients with previously treated non-MSI-high metastatic CRC. The dual primary endpoints of the study are OS in the ITT population and in the NLM subgroup of patients. The ITT population consisted of all randomized patients, regardless of the presence of liver metastases. The NLM subgroup consisted of patients who did not have active liver metastases at baseline as determined by investigator assessment. Secondary endpoints include PFS, objective response rate and duration of response in the ITT population and in the NLM subgroup of patients. More information about the trial is available at ClinicalTrials.gov.

About Zanzalintinib
Zanzalintinib is a novel oral kinase inhibitor that inhibits the activity of the TAM kinases (TYRO3, AXL, MER), MET and VEGF receptors. These kinases play important roles in oncogenic processes, including tumor cell proliferation, metastasis, angiogenesis, drug resistance and evasion of antitumor immunity. With zanzalintinib, Exelixis sought to build upon its extensive experience with the target profile of cabozantinib, the company’s flagship medicine, while improving key characteristics, including pharmacokinetic half-life. Zanzalintinib is currently being developed for the treatment of advanced solid tumors, including colorectal cancer, kidney cancer and neuroendocrine tumors.

Zanzalintinib is an investigational agent that is not approved for any use and is the subject of ongoing clinical trials.

About CRC
CRC is the third most common cancer and a leading cause of cancer-related deaths in the U.S.1 Approximately 159,000 new cases will be diagnosed in the U.S. in 2026, with around 55,000 expected deaths from the disease.1 CRC is most frequently diagnosed among people aged 65-74 and is more common in men and in people of non-Hispanic American Indian/Alaska Native descent.2 Nearly a quarter of CRC cases are diagnosed at the metastatic stage, at which point the five-year survival rate is around just 15%.1,2 The liver is the most common site for CRC metastasis. Liver metastases significantly impact survival, with a median five-year survival rate of less than 14% when treated with palliative chemotherapy.

On February 2, 2026 ImmunityBio, Inc. (NASDAQ: IBRX), a commercial-stage immunotherapy company, reported the launch of ResQ215B, a Phase 2 clinical study evaluating a novel chemotherapy-free and lymphodepletion-free combination immunotherapy in patients with indolent B-cell non-Hodgkin lymphoma (iNHL), including Waldenström’s Macroglobulinemia.

The outpatient study evaluates ImmunityBio’s novel, off-the-shelf CD19-targeted high-affinity natural killer (NK) cell therapy (CD19 t-haNK) in combination with nogapendekin-alfa inbakicept (NAI; ANKTIVA), an IL-15 superagonist, and the anti-CD20 monoclonal antibody rituximab. Notably, the regimen does not require any lymphodepleting chemotherapy, distinguishing it from conventional CAR-T cell therapies.

ResQ215B builds on promising results from the Phase 1 QUILT-106 study (NCT06334991), which evaluated CD19 CAR-NK cell therapy in combination with the anti-CD20 rituximab (without ANKTIVA). In that study, durable complete responses were observed in heavily pretreated patients with iNHL, including Waldenström’s Macroglobulinemia.

In an initial chemotherapy-free cohort of patients with Waldenström’s Macroglobulinemia treated with CD19 CAR-NK cells plus rituximab without any lymphodepletion, all four patients achieved clinical disease control. Two patients achieved rapid complete remissions (CR) that remain ongoing at 7 and 15 months of follow-up, respectively, without additional therapy beyond the planned treatment courses. The other two patients achieved stable disease, including one patient with declining IgM levels. These early findings demonstrated a 100% disease control in this small cohort using an outpatient, off-the-shelf CAR-NK cell therapy plus antibody combination without chemotherapy or inpatient hospitalization.

With the addition of ANKTIVA, ResQ215B is designed to evaluate whether further stimulation of innate and adaptive immune responses may enhance the depth and durability of anti-tumor activity. ANKTIVA is designed to promote the proliferation and activation of NK cells and CD8* T cells, potentially augmenting CAR-NK-mediated cytotoxicity and rituximab-driven ADCC.

Preclinical and clinical data suggests that IL-15 agonists may help restore immune function in the face of antibody resistance. In a previously published Phase 1 study (NCT02384954) Foltz et al. reported that combining an IL-15 superagonist with rituximab achieved a 78% complete response rate in patients with relapsed iNHL who had previously failed rituximab therapy.

"Our BioShield platform, which combines cell therapy, our IL-15 superagonist, and a monoclonal antibody in an outpatient, chemotherapy-free setting, represents our vision for Immunotherapy 2.0," said Patrick Soon-Shiong, M.D., Founder, Executive Chairman, and Global Chief Medical and Scientific Officer of ImmunityBio. "Building on the durable complete remissions observed with our CD19 CAR-NK cell therapy plus rituximab in Waldenström’s Macroglobulinemia, we are now adding ANKTIVA to further arm the immune system. We believe this off-the-shelf immunotherapy platform can trigger powerful anti-tumor activity without the toxicities of traditional treatments, potentially transforming the treatment paradigm for patients with indolent B-cell malignancies."

"A therapy that does not require apheresis, individualized manufacturing, chemotherapy, or inpatient hospitalization would represent an important advance for patients with iNHL, who are regarded as having incurable lymphomas," said Lennie Sender, M.D., Chief Medical Officer for Cell Therapy and Liquid Tumors at ImmunityBio. "To date, all treated patients have received the therapy in an outpatient setting without significant immune-related toxicities, demonstrating the feasibility of delivering potent cellular therapy without hospital admission. With ResQ215B, we will evaluate whether adding ANKTIVA can further improve response rates and durability while maintaining this favorable safety profile. This could open the door to a more patient-friendly immunotherapy option for follicular lymphoma, Waldenström’s, and other indolent NHL subtypes that currently rely on more aggressive or continuous treatments. Indolent B-cell lymphomas, such as Waldenström’s Macroglobulinemia, remain an area of high unmet medical need."

About the ResQ215B Study

ResQ315B is a Phase 2, open-label study designed to evaluate whether the addition of ANKTIVA can enhance immune-mediated tumor control when combined with CD19 CAR-NK cells and rituximab. The study will enroll adults with CD19⁺/CD20⁺ indolent NHL, including Waldenström’s Macroglobulinemia, who are relapsed or are refractory after at least two prior lines of therapy. Treatment will be administered in 21-day outpatient cycles without preconditioning chemotherapy.

About CD19 t-haNK

ImmunityBio’s CD19 t-haNK is an off-the-shelf, allogeneic NK-92-based cell therapy genetically engineered to express a CD19-specific chimeric antigen receptor (CAR) and a high-affinity CD16 (FcγRIIIa 158V) receptor. This dual-engineered design enables two complementary mechanisms of action: direct CAR-mediated cytotoxicity against CD19-expressing malignant B cells, and augmented antibody-dependent cellular cytotoxicity (ADCC) when paired with an anti-CD20 antibody such as rituximab. By targeting both CD19 and CD20, the combination is designed to reduce immune escape and improve overall response rates.

On February 2, 2026 Onchilles Pharma, a private biotech company pioneering next-generation cytotoxic therapeutics that harness the ELANE pathway, reported the U.S. Food and Drug Administration (FDA) clearance of its Investigational New Drug (IND) application for N17350 to initiate first-in-human clinical studies in patients with advanced solid tumors. N17350, the company’s first-in-class tumor-directed therapeutic candidate, leverages the ELANE pathway, an innate immune mechanism that selectively kills a wide range of cancer cells while preserving and activating the immune system.

"IND clearance for N17350 marks an important milestone for Onchilles and reflects years of rigorous work establishing the ELANE pathway as a clinically actionable mechanism to improve the treatment of cancer," said Lev Becker, Ph.D., Co-Founder and Chief Scientific Officer of Onchilles Pharma. "From the beginning, this work was driven by fundamental observations in patients. What emerged was a mechanism that broadly kills cancer cells while preserving and activating immune cells, thereby transforming cancer cell death into long-lasting anti-tumor immunity. We now have the opportunity to evaluate in the clinic a differentiated, cancer-selective mechanism that overcomes limitations of current treatment paradigms."

N17350 demonstrated consistent efficacy in preclinical models spanning dozens of cancer cell lines, patient-derived samples, and multiple in vivo models, including chemotherapy-resistant and immunologically "cold" tumors, where it induced immunogenic cancer cell death and drove CD8+ T cell–mediated immune activation. These findings support its evaluation in a broad first-in-human clinical study.

"The preclinical data supporting N17350 suggest a mechanism that kills tumors and simultaneously primes the immune system," said Alain P. Algazi, M.D., Onchilles N17350 Clinical Advisory Board Chair and Director, Program Leader, UCSF Head and Neck Medical Oncology. "If this dual activity translates clinically, it could represent a meaningful advance for patients with tumors that are difficult to treat with existing cytotoxic or immunotherapy approaches."

The first-in-human study will evaluate the safety, tolerability, and preliminary clinical activity of N17350 as a monotherapy in patients with advanced solid tumors, including melanoma, head and neck neoplasms, squamous cell carcinoma of skin, non-small-cell lung carcinoma, triple-negative breast neoplasms (ClinicalTrials.gov Identifier: NCT07339176). The trial is also designed to assess pharmacodynamic biomarkers associated with ELANE pathway engagement and immune activation, providing early clinical insight into the mechanism. Onchilles plans to initiate first-in-human dosing at multiple sites in the U.S. and Australia.

"N17350 is fundamentally different from traditional cytotoxic chemotherapies or immunotherapies," said Court R. Turner, J.D., Co-Founder and Chief Executive Officer of Onchilles Pharma. "By leveraging the ELANE pathway, we are advancing a cancer-selective therapeutic approach designed to eliminate tumors as well as preserve and train the immune system to respond at the same time. As we move into clinical testing, we believe this approach has the potential to address unmet needs across many different tumor types."

About Onchilles Therapeutic Programs Targeting the ELANE Pathway

At the core of this approach is the ELANE pathway, a unique cancer-selective killing mechanism that leverages a vulnerability shared by many cancer cell types: elevated histone H1 levels. By targeting the ELANE pathway and inducing immunogenic cancer cell death, N17350 and NEU-002 are designed to rapidly eliminate tumors while mobilizing an adaptive immune response, offering the potential for sustained anti-tumor immunity. N17350 and NEU-002 offer a unique approach to treating cancer regardless of their genetic makeup, anatomical origin, or immune status, positioning them as potential game-changers in cancer therapy.
