Operating Highlights
Sabirnetug: Progressed in Phase II ALTITUDE-AD trial, targeting synaptotoxic amyloid beta oligomers for Alzheimer's treatment. Demonstrated positive effects on biomarkers like pTau181 and neurogranin in Phase Ib study.
Enhanced Brain Delivery (EBD) Program: Partnership with JCR Pharmaceuticals to enhance brain penetration and distribution of antibodies. Preclinical data showed 14-40x higher brain levels in nonhuman primates compared to native antibody control. Targeting IND filing by mid-2027.
Private Placement Funding: Raised $35.75 million in March 2026 to support EBD program and general corporate purposes. Funding validates Enhanced Brain Delivery strategy.
Financial Position: Ended 2025 with $116.9 million in cash and marketable securities, supporting operations into early 2027. R&D expenses increased to $104.9 million due to ALTITUDE-AD trial and EBD research.
Cost Management: G&A expenses decreased to $18.9 million due to reductions in recruiting, insurance, and consulting costs.
Pipeline Expansion: Expanded pipeline with EBD program to develop next-generation Alzheimer's therapies. Focused on innovation and improved treatment options.
Future Development Plans: Plans to read out ALTITUDE-AD trial results in late 2026 and advance EBD program with IND filing targeted for mid-2027.

Risk or Challenges
Clinical trial risks: The success of the ALTITUDE-AD Phase II trial is critical for the company's future strategy. Any negative results or safety concerns could significantly impact the company's development plans and financial outlook.
Regulatory hurdles: The development of new therapies, including the EBD program, is subject to regulatory approval processes, which could delay or prevent market entry.
Financial sustainability: The company reported a net loss of $121.3 million in 2025 and is reliant on its current cash reserves and recent private placement to fund operations into early 2027. Any delays or additional costs could strain financial resources.
Market competition: The Alzheimer's treatment space is highly competitive, with other companies also targeting A-beta oligomers and developing innovative therapies. This could limit market share and revenue potential.
Supply chain and manufacturing challenges: Increased R&D expenses were partly due to manufacturing and material costs for the ALTITUDE-AD trial. Any disruptions in the supply chain or manufacturing processes could delay clinical trials and product development.

Guidance & Outlook
ALTITUDE-AD Phase II trial: Expected to read out late 2026, including key clinical efficacy and safety measures. Results will inform development strategy and understanding of the impact of clearing A-beta oligomers in Alzheimer's patients.
Enhanced Brain Delivery (EBD) program: Targeting an IND filing for a clinical candidate in mid-2027. Preclinical data shows potential for significantly enhanced brain distribution and lower safety risks, with subcutaneous dosing format.
Financial outlook: Cash and marketable securities of $116.9 million expected to support clinical and operational activities into early 2027. Recent $35.75 million private placement to primarily support EBD program development.

Key Q&A
Q:How has patient retention been in the ALTITUDE-AD study, and how is it trending relative to initial assumptions?
A:Patient retention in the ALTITUDE-AD study has been in line with other major Alzheimer's trials. The rollover rate into the open-label extension (OLE) has also been very satisfying, suggesting good safety and tolerability. However, as the study is blinded, no definitive conclusions can be drawn until the study is unblinded.
Q:What has been observed in preclinical studies for EBD candidates, and what gives confidence in their efficacy?
A:Preclinical studies in rodent models and primates have shown 14- to 40-fold improvements in brain exposure with EBD candidates. Multiple candidates have shown enhanced brain penetration and favorable profiles, including pharmacokinetics and distribution. This progress gives confidence in their potential efficacy.
Q:Are there plans to present additional non-human primate (NHP) preclinical data for the EBD program?
A:Yes, the company plans to continue presenting data from the EBD program at upcoming scientific meetings. They have already shared data from humanized mouse models and NHP studies and will provide more details as the preclinical program progresses.
Q:How does the EBD program improve brain penetration and distribution compared to existing antibodies?
A:The EBD program shows 14- to 40-fold improvements in brain penetration. The technology allows for broader distribution of antibodies in the brain, reaching deeper cortical layers and areas not accessible with non-carrier-mediated antibodies. This enhanced distribution is expected to improve efficacy.
Q:What is the distribution of A-beta oligomers in the brain, and how does the EBD program address this?
A:A-beta oligomers are broadly distributed across cortical and subcortical regions. The EBD program's technology enables antibodies to penetrate fine capillaries throughout the brain, ensuring broad distribution and potentially better targeting of oligomers.
Q:Why are lower rates of anemia observed with the EBD program compared to other transferrin antibodies?
A:The lower rates of anemia are attributed to the specific epitopes targeted by JCR's transferrin receptor technology. Non-human primate studies have shown minimal effects on reticulocyte counts, consistent with JCR's clinical findings.
Q:How does the company compare its brain uptake ratios to competitors?
A:The company reports robust improvements in brain uptake ratios (14- to 40-fold) relative to baseline levels. However, they avoid direct comparisons with competitors like Roche, as no head-to-head studies have been conducted.
Q:What will be measured in the OLE study, and what are the expectations for plaque clearance after 18 months?
A:The OLE study will measure the same biomarkers as the main study but less frequently. While some plaque reduction was observed in Phase I, the company cannot predict whether plaque levels will continue to decrease or plateau after 18 months. Plaque reduction is not necessarily required for efficacy, as the drug targets oligomers.
Q:What are the plans for the EBD program's early-stage trial design?
A:The early-stage trial for the EBD program will likely include Alzheimer's patients to gather safety, tolerability, and biomarker data. The study may also explore longer dosing durations compared to previous trials.
Q:What feedback has been received from physicians about sabirnetug's potential to address unmet needs?
A:Physicians acknowledge room for improvement in current Alzheimer's treatments. Sabirnetug's IgG2 profile, which may reduce serious adverse events like ARIA, is seen as a potential advantage over IgG1 drugs. The company will compare safety and efficacy data with existing treatments after the Phase II readout.
Q:Why was the 35 mg/kg dose chosen for the OLE study?
A:The 35 mg/kg dose was selected based on Phase I data showing good target engagement at both peak and trough levels. While 50 mg/kg provides an additional safety margin, 35 mg/kg is considered a viable dose for testing the oligomer hypothesis.
Q:What is the company's current thinking on Phase III design if ALTITUDE-AD is positive?
A:The company plans to conduct a single additional Phase III study with a design similar to ALTITUDE-AD but with a larger population. This approach is based on FDA interactions and the precedent set by other Alzheimer's drug approvals.
Q:Review of Unclear Management Responses
A:Management avoided providing direct answers to questions about specific retention and rollover rates in the ALTITUDE-AD study, as well as detailed comparisons to other studies like lecanemab and donanemab. They also did not provide specific data on brain uptake amounts for EBD candidates, citing variability and lack of head-to-head comparisons.
