About the REZILIENT3 Trial

This multicenter, randomized, controlled, open-label global trial enrolled 285 adults with previously untreated, locally advanced or metastatic non-squamous NSCLC with EGFR exon 20 insertion mutations. The primary objective of this trial is to assess progression-free survival in the zipalertinib plus chemotherapy arm versus the chemotherapy arm.

About Zipalertinib

Zipalertinib (development code: CLN-081/TAS6417) is an orally available small molecule designed to target activating mutations in EGFR. The molecule was selected because of its ability to inhibit EGFR variants with exon 20 insertion mutations. Zipalertinib is designed as a next generation, irreversible EGFR inhibitor for the treatment of a genetically defined subset of patients with non-small cell lung cancer. Zipalertinib is investigational and has not been approved by any health authority.

Zipalertinib is being developed by Taiho Oncology, Inc., its parent company, Taiho Pharmaceutical Co., Ltd., and in collaboration with Cullinan Therapeutics, Inc. in the U.S.

About EGFR Exon 20 Insertion Mutations

NSCLC is a common form of lung cancer and up to 4% of all cases globally have EGFR ex20ins.1 In the United States, approximately 16% of patients with NSCLC harbor EGFR mutations,1 with insertions at exon 20 accounting for up to 12% of these mutations.

The FDA-approved prescribing information for ZENBEXUS states that minimal residual disease (MRD)-negative complete response, the trial’s major efficacy outcome measure, was assessed "based on a threshold of 10⁻⁵ using a Hematogenix Next Generation Flow Cytometry assay." In the Phase 3 EXCALIBER-RRMM trial, patients treated with ZENBEXUS in combination with daratumumab and hyaluronidase-fihj and dexamethasone (ZDd) achieved an MRD-negative complete response rate of 41%, compared with 21% for patients treated with daratumumab, bortezomib, and dexamethasone (DVd) — a statistically significant improvement (p<0.0001) that formed the basis of the FDA’s approval decision.

"Being named directly in the FDA label for the first approved therapy in a novel drug class is a meaningful validation of the precision and scientific rigor our laboratory brings to this new era of innovative therapies," said Dr. Hytham Al-Masri, President and CEO of Hematogenix. "Multiple myeloma treatment is moving toward MRD negativity as a defining measure of treatment success, and we are proud that our MM MRD flow cytometry platform is trusted to generate the data that regulators, physicians, and patients relying upon."

MRD negativity, measured at a sensitivity threshold of one residual tumor cell among 100,000 normal cells, is increasingly recognized by regulatory authorities as a surrogate endpoint capable of supporting accelerated approval pathways in multiple myeloma, a use case for which specialized, standardized assay methodology is essential. Hematogenix’s NGF MRD platform for MM, AML and CLL is designed to meet the sensitivity, reproducibility, and regulatory-grade standards required for these registrational endpoints across sponsors’ global multicenter trial sites.

This milestone reflects Hematogenix’s broader positioning as an agile, specialized reference laboratory and CRO supporting registrational-grade endpoints for major pharmaceutical sponsors, with CAP-accredited and CLIA certified laboratories across the globe, including the United States, United Kingdom, Malaysia, and China.

About ZENBEXUS (iberdomide) ZENBEXUS is indicated, in combination with daratumumab and hyaluronidase-fihj and dexamethasone, for the treatment of adult patients with multiple myeloma who have received at least one prior line of therapy including a proteasome inhibitor and an immunomodulatory agent. This indication is approved under accelerated approval based on MRD-negative complete response at any time; continued approval may be contingent upon verification of clinical benefit in confirmatory trials. ZENBEXUS carries a Boxed Warning for embryo-fetal toxicity and serious venous and arterial thromboembolism and is available only through the ZENBEXUS REMS program. Full prescribing information, including additional warnings and precautions, is available from Bristol Myers Squibb.

On August 19, 2026 BioArctic AB (publ) (NASDAQ Stockholm: BIOA B) and Mesenkia Therapeutics reported that the companies have signed a research collaboration agreement to explore a novel antibody-based approach for glioblastoma, one of the most aggressive and treatment-resistant forms of brain cancer, where effective delivery of large molecules to the brain remains a major challenge.

The collaboration combines BioArctic’s proprietary BrainTransporter technology with an antibody, developed with Mesenkia’s KITAIbodies platform. The antibody targets HVEM[1], a protein found on the surface of certain glioblastoma tumor cells, including tumor stem cells. By addressing these cells, which are thought to contribute to tumor recurrence and treatment resistance, the project aims to unlock new treatment possibilities for patients with a very high unmet medical need.

Under the agreement, BioArctic will be responsible for generating a novel drug candidate by combining its BrainTransporter technology with Mesenkia’s antibody. BioArctic and Mesenkia thereafter plan to perform preclinical studies to validate the concept and, based on the results of these studies, decide on next steps.

This research collaboration represents an important step in expanding BioArctic’s BrainTransporter pipeline into oncology and further validates the platform’s potential beyond neurodegenerative diseases. It also builds on BioArctic’s core expertise in development and delivery of pharmaceuticals to the brain.

"We are excited to broaden our research and take a first step into oncology through this collaboration," said Gunilla Osswald, Chief Executive Officer of BioArctic. "Glioblastoma remains one of the most challenging cancers to treat, with limited therapeutic options and poor prognosis for those affected. By combining our BrainTransporter technology with Mesenkia’s innovative antibody approach, we aim to target key disease-driving mechanisms to develop new ways to treat this devastating disease."

"This agreement marks an important step for Mesenkia and creates clear opportunities to explore a new treatment strategy for patients with glioblastoma together with BioArctic. The need for new treatments is substantial, particularly given the challenge of delivering medicines to tumor cells throughout the brain. By combining Mesenkia’s antibody expertise with BioArctic’s BrainTransporter technology, we can address one of the disease’s key barriers in a new way. We look forward to advancing the concept together with BioArctic, with the long-term goal of enabling better treatment options for patients and their loved ones," said Moa Fransson, Chief Executive Officer of Mesenkia.

"We are excited to expand our clinical collaboration with Roche to evaluate a second KRAS combination with potential best-in-class MTA-cooperative PRMT5 inhibitor IDE892 for pancreatic cancer patients, where there remains a high unmet medical need. IDEAYA is advancing multiple rational combination strategies for the IDE892 program, including with MAT2A inhibitor IDE397, pan-RAS inhibitors, KRAS G12D inhibitors, and IDEAYA’s lead CDKN2A compound," said Yujiro S. Hata, President and Chief Executive Officer, IDEAYA Biosciences.

IDE892 has potential best-in-class properties, including approximately 1,400-fold selective MTA-PRMT5 cooperative binding versus SAM-PRMT5 cooperative binding and lack of brain penetrance intended to maximize its therapeutic window, and favorable drug-like properties to enable rational combinations with IDE397, pan-RAS inhibitors, KRAS-mutant specific therapies, and IDEAYA’s CDKN2A lead molecule. IDE892 has a CYP3A4 IC50 greater than 45 micromolar and did not show time dependent inhibition of any of the 7 major cytochrome P450s (CYP1A2, CYP2B6, CYP2C8, CYP2C9, CYP2C19, CYP2D6, CYP3A4) based on full kinetic CYP inactivation assays, positioning IDE892 as a potential best-in-class MTA-cooperative PRMT5 combination partner. IDEAYA is evaluating IDE892 in a Phase 1 dose escalation and expansion clinical trial in MTAP-deleted solid tumors and has initiated a Phase 1 combination cohort in NSCLC and other solid tumors with IDE397, IDEAYA’s proprietary MAT2A inhibitor. IDEAYA also plans to initiate a Phase 1 combination cohort with Roche’s RG6505 in MTAP-deleted, RAS-mutant PDAC in 2H 2026. The collaboration announced today adds GDC-7035 as an additional KRAS-directed combination partner for IDE892 in MTAP-deleted, KRAS G12D positive PDAC.

MTAP deletions and KRAS G12D mutations are estimated to co-occur in up to approximately 15% of PDAC patients. Combining a PRMT5 inhibitor with a KRAS G12D mutant-specific inhibitor may have the potential to drive deeper and more durable responses for those PDAC patients with co-occurring alterations, who currently have no approved targeted treatment options.

Under the clinical collaboration, IDEAYA and Genentech each retain all commercial rights to their respective compounds, including as monotherapy and as combination therapies. There will be joint governance to oversee the clinical supply collaboration.
