The approval enables Guardant360 CDx, a liquid biopsy test that analyzes circulating tumor DNA (ctDNA) from a simple blood draw, to identify patients with HER2 (ERBB2) tyrosine kinase domain activating mutations who may be eligible for treatment with HERNEXEOS.

HERNEXEOS is indicated for the treatment of adult patients with unresectable or metastatic non-squamous NSCLC whose tumors have HER2 (ERBB2) tyrosine kinase domain activating mutations, as detected by an FDA-authorized test. This indication was approved under accelerated approval based on objective response rate and duration of response. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial. More information and full prescribing information can be found at HERNEXEOS.com.

"This approval highlights the growing impact of liquid biopsy across advanced cancer care and underscores the utility of Guardant360 CDx to ensuring more patients can be matched to the right therapy at the right time," said Helmy Eltoukhy, Guardant Health chairman and co-CEO. "Guardant360 CDx has been at the forefront of enabling comprehensive genomic profiling through a simple blood draw, helping clinicians identify actionable mutations in genes such as HER2 with speed and accuracy."

Guardant360 CDx was the first FDA-approved liquid biopsy that provides comprehensive genomic profiling across multiple tumor types and biomarkers. By detecting tumor-derived alterations in circulating cell-free DNA, the test helps clinicians match patients to appropriate targeted therapies and clinical trials.

"Companion diagnostics are essential to personalized lung cancer care, guiding biomarker-driven treatment decisions," added Vicky Brown, U.S. Therapeutic Area Head for Oncology and Emerging Areas, Boehringer Ingelheim. "Guardant360 CDx will help identify patients with HER2-mutant advanced non-small cell lung cancer and connect eligible patients to the appropriate targeted therapy when timely treatment decisions matter most."

NSCLC is the most common type of lung cancer, and a subset of patients harbor HER2 mutations that may be targetable with precision therapies. HER2-mutant NSCLC is an aggressive type of lung cancer that has been associated with a poor prognosis. Blood-based testing offers a faster, less invasive alternative to tissue biopsy, which can be challenging in advanced disease.

This latest FDA approval for Guardant360 CDx marks the 27th CDx indication across multiple tumor types globally, building on the platform’s increasing clinical utility and broad coverage by Medicare and commercial payers, representing more than 300 million covered lives.

"Dosing the first patient in QUATRO-APL is an important clinical development milestone for Quetzal," said Usman Ahmed, Chief Executive Officer and Chairman of Quetzal Therapeutics. "We look forward to continued enrollment and to working with our investigators, clinical sites, and partners as the trial progresses."

"Current standard-of-care regimens for APL require a significant number of intravenous infusions over the course of therapy, which can be burdensome for patients and healthcare systems," said Shaad Abedin, M.D., Chief Medical Officer of Quetzal Therapeutics. "QUATRO-APL is designed to evaluate whether an oral formulation of arsenic trioxide can offer a potential alternative to intravenous administration. We are grateful to the investigators, site teams, and partners whose commitment made this milestone possible."

Quetzal Therapeutics expects continued site activation and patient enrollment across the United States and Europe as the global Phase 3 program advances and plans to provide additional updates on study progress as enrollment continues.

About the QUATRO-APL Trial

QUATRO-APL (QTX-2101-301) is a pivotal, open-label Phase 3 clinical study evaluating the efficacy, safety, and pharmacokinetics of QTX-2101, an oral capsule formulation of arsenic trioxide, in combination with all-trans retinoic acid (ATRA), in adult patients with newly diagnosed, low-risk acute promyelocytic leukemia. The comparator arm is intravenous arsenic trioxide plus ATRA.

Additional information is available at ClinicalTrials.gov (NCT07504458) and the EU Clinical Trials Information System (2025-524810-28-00).

About Acute Promyelocytic Leukemia

APL is a rare and aggressive subtype of acute myeloid leukemia, accounting for approximately 10-15% of all AML cases. It is defined by the PML-RARA gene fusion and is associated with severe bleeding complications and rapid disease progression if untreated. While advances in therapy have transformed outcomes, current treatments often require patients to undergo a large number of lengthy intravenous infusions over the course of therapy. This relentless treatment schedule can disrupt daily life and place a significant burden on both patients and their support networks. There remains a clear need for innovative and more accessible therapies.

"By providing a standardised testing option for mismatch repair status with our VENTANA MMR RxDx Panel, we are empowering clinicians to make more informed decisions and expanding access to important therapies for patients across multiple solid tumor types," said Laura Apitz, Head of Pathology Lab at Roche Diagnostics. "This milestone exemplifies our dedication to delivering high-medical-value solutions that help improve patient outcomes through precision medicine."

The VENTANA MMR RxDx Panel is now available in countries regulated by IVDR as a companion diagnostic for the following therapies and cancer types:

KEYTRUDA (pembrolizumab), Merck & Co., Inc., Rahway, NJ, USA’s anti-PD-1 therapy: For the treatment of mismatch repair deficient (dMMR) tumors in certain adults with: metastatic colorectal cancer; advanced or recurrent endometrial carcinoma; unresectable or metastatic gastric, small intestine or biliary cancer.
IMFINZI (durvalumab), AstraZeneca’s anti-PD-L1 therapy: For adult patients with dMMR primary advanced or recurrent endometrial cancer.
IMFINZI + LYNPARZA (olaparib), AstraZeneca’s anti-PD-L1 therapy and PARP inhibitor: For adult patients with mismatch repair proficient (pMMR) primary advanced or recurrent endometrial cancer.
JEMPERLI (dostarlimab-gxly), GSK’s anti-PD-1 therapy: for dMMR patients with endometrial cancer.1
About MMR
Cancer remains the second leading cause of death worldwide, resulting in nearly 10 million deaths annually.2, 3 Identifying specific biomarkers is critical to help identify patients who are eligible for certain therapies, as dMMR serves as a vital predictive biomarker for modern immunotherapies.

MMR is a naturally occurring mechanism that scans our DNA, correcting errors that cause disease. When MMR is deficient, cells mutate, which can lead to cancer. While MMR deficiency is most common in endometrial cancer, other high-prevalence dMMR tumour types include gastric, colorectal, small intestine and biliary tract cancers. Because dMMR tumours often have a high mutational burden they may respond well to immune checkpoint inhibitors (ICIs) such as PD-1 or PD-L1 inhibitors. For patients with endometrial cancer without MMR deficiency (pMMR), the addition of PARP inhibitors in maintenance to ICIs may further enhance the benefit of ICIs. PD-1 inhibitors may retain activity when combined with a tyrosine kinase inhibitor (TKI).

About the VENTANA MMR RxDx Panel
This IVDR approval for the VENTANA MMR RxDx Panel is a label expansion of Roche’s current on-market panel. The VENTANA MMR RxDx Panel is intended for the assessment of expression of MMR proteins in formalin-fixed, paraffin-embedded (FFPE) tumour tissue stained with OptiView DAB IHC Detection Kit and ancillary reagents in the panel for VENTANA anti-MLH1 (M1), VENTANA anti-MSH2 (G219-1129) and VENTANA anti-MSH6 (SP93), and OptiView DAB IHC Detection Kit with the OptiView Amplification Kit and ancillary reagents for VENTANA anti-PMS2 (A16-4) on a BenchMark ULTRA instrument.

MMR proteins have been clinically proven to be predictive biomarkers for PD-1 targeted therapy; specifically, a loss of expression of one or more MMR proteins might predict an increased likelihood of response to such therapy.4,5,6 PD-1 inhibitors can be effective in cancers with MMR deficiency.4,6 MMR is a conserved molecular mechanism that functions to correct the improper base substitutions that spontaneously occur during DNA replication. Defects in the MMR machinery have been attributed to mutations in the MMR proteins.

"In Q1 2026 our focus remained on strategic discussions with potential partners to support the Phase 2b development of varoglutamstat in advanced DKD. We continue to make substantial progress and remain actively engaged with multiple parties who, like us, understand the need for disease-modifying therapeutics that could improve or stabilize kidney function," said Frank Weber, MD, CEO of Vivoryon. "We have consistently shown that varoglutamstat improves kidney function in elderly patients, in particular those with diabetes, and have established a large pre-clinical and clinical data set to de-risk the planned Phase 2b program. Taken together, these data give us further confidence that, through its differentiated mechanism of action targeting fibrotic and inflammatory pathways, varoglutamstat could have a transformative role in preventing progression of life-limiting kidney diseases."

Q1 2026 and Post-Period Updates

Strategic Priorities
Vivoryon’s key strategic priority for 2026 is to secure the funding necessary to advance varoglutamstat into a Phase 2b clinical study in patients with advanced DKD stage 3b/4 in order to confirm the compelling data observed in the VIVIAD and VIVA-MIND studies. Throughout the reporting period and recent months, the Company has continued to engage in active discussions and due diligence under CDA with multiple potential biopharma partners and strategic investors.

Varoglutamstat Program

Vivoryon’s varoglutamstat Phase 2 program has shown highly consistent, statistically significant and clinically meaningful improvement of kidney function (eGFR) versus placebo in two independent randomized double-blind placebo-controlled studies, VIVIAD and VIVA-MIND. The Company is planning to confirm these results in a dedicated Phase 2b clinical study in patients with DKD stage 3b/4. Initiation of the Phase 2b and all future studies is subject to additional funding and/or partnership, which Vivoryon continues to actively explore.

On March 28, 2026, Vivoryon presented a poster at the World Congress of Nephrology (WCN) in Yokohama, Japan, providing an update on the growing body of evidence validating glutaminyl cyclases (QPCT/L) as promising targets in DKD. The analyses underscored previous reports showing that the effect of varoglutamstat on eGFR observed in VIVIAD and VIVA-MIND was greater in elderly participants with diabetes compared to elderly participants without diabetes. In participants with diabetes and lower baseline eGFR (mean 60 mL/min/1.73m2), the effect size was comparable or higher than in the total population of participants with diabetes. Additionally, analysis of data from a DKD mouse model showed significant improvements of inflammation, glomerulosclerosis and kidney function. These results further support Vivoryon’s rationale for a dedicated Phase 2b clinical study in patients with advanced DKD stage 3b/4.
The Company has actively expanded the pre-clinical data set around varoglutamstat’s mechanism of action (MOA) and recent studies have further elucidated the molecular mechanisms underlying the substantial benefits reported from the VIVIAD and VIVA-MIND studies. On April 22, 2026, the Company published on its website a pre-recorded webcast contextualizing these new data. The webcast includes new data on the role of QPCT and QPCTL in inflammation and fibrosis, including revealing their newly discovered role in collagen maturation, the disruption of which is a key factor in fibrosis, as well as new data on the existing medical need in kidney disease and the positive effect of varoglutamstat treatment on specialized blood-filtering kidney cells (podocytes). The webcast is available here:

Proposed clinical development plan in DKD
The Company is planning to conduct a randomized, placebo-controlled Phase 2b study in patients with advanced DKD stage 3b/4 to confirm the compelling effects of varoglutamstat on kidney function observed in the VIVAD and VIVA-MIND Phase 2 studies in elderly patients. Initiation of the Phase 2b and all future studies is subject to additional funding and/or partnership, which Vivoryon continues to actively explore.

Financial Results for the First Quarter of 2026

No Revenues were generated in the three months ended March 31, 2026.

Research and development expenses decreased by EUR 0.3 million to EUR 0.9 million in the three months ended March 31, 2026, compared to EUR 1.2 million in the three months ended March 31, 2025. This decrease is primarily attributable to EUR 0.2 million lower third-party expenses due to the ramp-down of the Phase 2b clinical studies VIVIAD and VIVA-MIND, reflecting EUR 0.1 million lower clinical costs and EUR 0.1 million lower manufacturing costs.

General and administrative expenses were EUR 0.9 million in the three months ended March 31, 2026, compared to EUR 1.3 million in the three months ended March 31, 2025. The EUR 0.4 million decrease was primarily attributable to lower personnel expenses of EUR 0.2 million and reduced legal costs of EUR 0.2 million. The decline in personnel expenses was mainly due to a EUR 0.2 million reduction in share-based payment expenses.

The net loss for the three months ended March 31, 2026 was EUR 1.8 million compared to EUR 2.5 million for the three months ended March 31, 2025.

As of March 31, 2026, Vivoryon held cash and cash equivalents of EUR 4.0 million compared to cash and cash equivalents of EUR 5.6 million as of December 31, 2025.

Outlook & financial guidance

As published on April 23, 2026, the issuance date of its annual Financial Statements 2025, the Company expects, based on its most recent financial and business plan, that its existing cash and cash equivalents will be sufficient to fund its operating plans into the fourth quarter of 2026, subject to the occurrence of unforeseen circumstances and without taking into account any funds from the SEPA as well as other potential additional financing transactions, if any.

This cash runway guidance reflects an overall reduction in cash utilization while prudently investing in preparing to execute on the Company’s kidney disease strategy. The initiation of the Phase 2b DKD study and all future studies is subject to further additional funding and/or partnership, which the Company continues to actively explore.

The viability of the Company’s business beyond its current guidance is dependent on its ability to raise additional funds to finance its operations which also depends on the success of its research and development activities such as those focusing on exploring opportunities in kidney disease.

The Company expects to have continued operating losses for the foreseeable future and the need to raise additional capital to finance its future operations. The Company has concluded that the ability to continue as a going concern in the financial year 2026, as stated in the Company‘s Annual Report 2025 published on April 23, 2026, depends on the ability to generate additional funding. Please refer to the Company’s Annual Report 2025 for further information.

Conference call and webcast

The Company’s next financial and business update conference call / webcast will be held in conjunction with the publication of its H1 results, anticipated in August.
