Flamingo-01 Progress to Date

The Company has achieved a major milestone by screening over 1,000 patients in Flamingo-01, continuing its screening rate of approximately 150 patients per quarter or the equivalent of 600 patients per year in approximately 40 US sites and 100 EU sites for a total of 140 active sites. The Company is considering a strategy to continue enrolling in both the HLA-A*02 and non-HLA-A*02 arms until interim analyses are conducted and the appropriate size of each arm can be further assessed.

CEO Snehal Patel commented, "Reaching 1,000 screened patients confirms that the interest from doctors and patients is high. The clinical site start-up activities in Europe in 2025 have further increased the momentum in the study. We are also receiving interest from other countries to join FLAMINGO-01, driven by patient interest. The high screening rate will give the Company many options, including the opportunity to continue enrollment through multiple interim analyses, the potential to realize higher enrollment rates and event rates, and the potential to maximize indications by analyzing efficacy across multiple HLA types in larger patient populations."

About FLAMINGO-01 and GLSI-100

FLAMINGO-01 (NCT05232916) is a Phase III clinical trial designed to evaluate the safety and efficacy of GLSI-100 (GP2 + GM-CSF) in HER2 positive breast cancer patients who had residual disease or high-risk pathologic complete response at surgery and who have completed both neoadjuvant and postoperative adjuvant trastuzumab based treatment. The trial is led by Baylor College of Medicine and currently includes US and European clinical sites from university-based hospitals and academic and cooperative networks with plans to open up to 150 sites globally. In the double-blinded arms of the Phase III trial, approximately 500 HLA-A*02 patients will be randomized to GLSI-100 or placebo, and up to 250 patients of other HLA types will be treated with GLSI-100 in a third arm. The trial has been designed to detect a hazard ratio of 0.3 in invasive breast cancer-free survival, where 28 events will be required. An interim analysis for superiority and futility will be conducted when at least half of those events, 14, have occurred. This sample size provides 80% power if the annual rate of events in placebo-treated subjects is 2.4% or greater.

The Phase II study randomised female participants (N=66) with HR+ and HER2-negative/HER2-low metastatic breast cancer (MBC) resistant to endocrine-based therapy (ET) including cyclin-dependent kinase 4/6 (CDK4/6) inhibitors or metastatic triple-negative breast cancer (mTNBC) not eligible for PD-(L)1-based therapy. Patients were randomised 1:1 to receive either 30 or 90 mg eftilagimod alfa (efti) in combination with paclitaxel to determine the optimal biological dose (OBD) consistent with the FDA’s Project Optimus initiative.

Both efti dosing levels on top of weekly paclitaxel in heavily pretreated metastatic breast cancer patients, who received a median of three prior lines of systemic therapy, led to strong objective response rates (ORR) and disease control rates (DCR) of 41.9% and 87.1% (30 mg efti) and 48.5% and 78.8% (90 mg efti), respectively, in the evaluable population (N=64). Time to onset of response (TTR) was comparable at 2.0 months (30 mg) versus 1.9 months (90 mg).

Additionally, both dosing levels elicited the desired pharmacodynamic (PD) response in line with efti’s mechanism of action with substantial increases in immune activation biomarkers including absolute-lymphocyte count (ALC) and interferon-gamma (IFN-γ). Data cut-off date for efficacy results was 15 September 2025.

Dr. Nuhad Ibrahim, Professor, Department of Breast Medical Oncology, Division of Cancer Medicine, The University of Texas MD Anderson Cancer Center noted, "Evaluating two biologically active doses allowed us to integrate clinical response data with meaningful pharmacodynamic readouts. In keeping with Project Optimus principles, the study generated rigorous comparative data in heavily pretreated metastatic breast cancer patients showing consistent efficacy measures and immune-activation signals across both arms, reinforcing efti’s novel mechanism of action and the clinical potential of this immunotherapy-chemo combination."

Tolerability at 90 mg was suboptimal including dose-limiting toxicities (DLT) and a higher proportion of local injection site reactions (LISR). In line with FDA guidance/advice and as previously reported on 13 October 2025, 30 mg of efti administered subcutaneously has been defined as the OBD.

The partnership draws upon CorriXR’s proprietary CRISPR-based gene editing platform targeting NRF2, InhaTarget’s proprietary formulation platform and strong experience in pulmonary drug development, and Merxin Ltd’s advanced inhalation device technology. Through their combined expertise, they aim to create a patient-friendly inhaled therapy that delivers targeted treatment directly to lung tumors, maximizing efficacy, minimizing systemic side effects, and offering new hope for patients facing one of the world’s deadliest cancers.

Innovative Therapeutic Approach

CorriXR’s patented non-viral gene editing platform disables the transcription factor NRF2, a master regulator of cellular stress responses and known driver of tumor treatment resistance. As reported in a recent paper published in Molecular Therapy Oncology, preclinical data in lung cancer models have demonstrated that disabling NRF2 can meaningfully resensitize tumor response to chemotherapy with minimal off-target effects.

The collaboration seeks to demonstrate effective delivery of the CorriXR compound via InhaTarget’s proprietary lipid-nanoparticle (LNP) formulation platform, which enables encapsulation of active ingredients for inhalation delivery. Merxin Ltd will contribute their customized and patented inhaler device technology for drug delivery to the lungs. Initial studies will be conducted in cell culture and in a lung carcinoma mouse model, with results expected in mid-2026.

Addressing Unmet Medical Needs

Lung cancer continues to be one of the leading causes of cancer-related deaths globally. The study will focus on treatment of squamous cell lung carcinoma (LUSC), a common and aggressive form of non-small cell lung cancer (NSCLC) that comprises 25 – 30% of worldwide cases. With over 380,000 new cases of LUSC diagnosed globally each year and a five-year survival rate below 15%, the need for new therapies is urgent. Chemotherapy plus immunotherapy (IO) or IO alone is the current standard for first-line treatment of LUSC but still typically results in progression after 8 months or less. Many patients develop treatment resistance, leaving limited options beyond dose escalation, which increases toxicity and intolerance and typically worsens quality of life.

Leadership Perspectives

Dr. Eric B. Kmiec, founder and CEO of CorriXR Therapeutics, stated, "This partnership represents a significant step forward in our mission to harness the power of CRISPR-based gene editing for the benefit of patients with cancer by slowing the growth of solid tumors and improving effectiveness of existing treatments. We are excited by the potential of this collaboration to target lung cancer using a non-invasive inhaled delivery approach, which would greatly improve the quality of life for patients."

Dr. Frédéric De Coninck, co-founder and CEO of InhaTarget Therapeutics, commented, "Combining our pulmonary drug delivery LNP platform with CorriXR’s groundbreaking science and Merxin’s device technology has the potential to reshape the landscape of lung cancer treatment. We are eager to advance work on this novel combination."

Dr. Philippe Rogueda, CBO and founder of Merxin Ltd., remarked, "Our advanced inhaler technology is designed to ensure non-invasive, precise, consistent delivery of novel therapeutics. We are excited to contribute to this vital effort and help bring innovative solutions to patients with lung cancer."
