Summary of Amgen Conference Call - February 12, 2026 Company Overview - **Company**: Amgen (NasdaqGS:AMGN) - **Focus**: Development of innovative therapies for autoimmune diseases and other conditions Key Products and Developments UPLIZNA - **Indications**: Plans to initiate Phase III studies for autoimmune hepatitis (AIH) and chronic inflammatory demyelinating polyneuropathy (CIDP) later in 2026 - **Mechanism**: B-cell depleter targeting CD19, effective in conditions driven by pathogenic B-cells - **Market Potential**: - CIDP prevalent pool in the U.S. estimated at 35,000 patients, with 7,000-10,000 new cases annually - AIH likely has a larger patient population, though exact numbers are difficult to ascertain - **Rationale**: Proven effectiveness in similar conditions like IgG4-related disease and generalized myasthenia gravis supports the potential for UPLIZNA in AIH and CIDP [1][2][3][4][6] Daxdilimab - **Indications**: Positive Phase II results in discoid lupus; previously failed in systemic lupus erythematosus (SLE) - **Mechanism**: Targets immunoglobulin-like transcript seven protein (ILT-7), depleting plasmacytoid dendritic cells involved in interferon production - **Clinical Results**: - Discoid lupus study met primary endpoint of reduced disease severity at week 24 - Secondary endpoint also showed clinical benefit - **Future Plans**: Considering Phase III study for discoid lupus, with potential for broader indications in autoimmune diseases driven by plasmacytoid dendritic cells [9][10][11][13][16] Dazodalibep - **Indications**: Targeting Sjögren's syndrome with two ongoing Phase III studies - **Mechanism**: Inhibits CD40 ligand, disrupting B-cell activation and downstream inflammatory cascades - **Clinical Management**: Current management is symptomatic; no definitive treatments exist - **Phase II Results**: Showed improvement in disease activity index and patient-reported outcomes, providing confidence for Phase III studies [18][26][29][32] TEZSPIRE - **Indications**: Recently expanded label for chronic rhinosinusitis with nasal polyps - **Mechanism**: Targets TSLP, addressing upstream drivers of inflammation, differentiating it from therapies targeting downstream cytokines (IL-4, IL-5, IL-13) - **Clinical Results**: Phase 3 Waypoint study showed significant reduction in nasal polyp severity and decreased need for surgery - **Market Potential**: High overlap between chronic rhinosinusitis and asthma (approximately 20% of asthma patients also have nasal polyps), enhancing TEZSPIRE's market reach [35][36][37][42][45] Eosinophilic Esophagitis (EoE) - **Unmet Need**: Current treatments are limited, primarily involving proton pump inhibitors and corticosteroids - **Prevalence**: Estimated at 1 in 700 people in the U.S. - **Phase III Study**: Expected data in the second half of 2026, with potential for TEZSPIRE to address this unmet need [47][49][51] Competitive Landscape - **Dazodalibep vs. Nipocalimab**: Dazodalibep is the first therapy to demonstrate efficacy in both subgroups of Sjögren's syndrome in Phase II, with ongoing Phase III studies to confirm its effectiveness [32][34] Future Outlook - **Execution Focus**: Amgen aims to build penetration in existing indications before exploring new ones for TSLP-targeted therapies - **Inhaled TSLP Therapy**: AMG 104, an inhaled TSLP antibody fragment, is in Phase II trials, with potential to provide an alternative to injected biologics for asthma management [65][66][70][74] Conclusion - Amgen is positioned to leverage its innovative therapies across multiple autoimmune conditions, with significant clinical data supporting the efficacy of its products. The company is focused on executing its current strategies while preparing for future opportunities in the evolving therapeutic landscape.

Climb Bio Conference Call Summary Company Overview - **Company Name**: Climb Bio - **Focus**: RNI (Receptor-Negative Immunology) with a focus on developing therapies for B-cell mediated diseases - **Key Programs**: - CD19 B-cell depleting therapy (Budo) - CLYM116, an anti-APRIL antibody - **Company Age**: Approximately 12 months since rebranding from Ellium Therapeutics [4][6] Key Points and Arguments Company Strategy and Differentiation - Climb Bio aims to leverage recent advancements in understanding B-cell mediated diseases to develop therapies that allow for drug-free remission [7] - The company is focused on scalable therapies using monoclonal antibodies rather than complex and costly cell therapies like CAR-T [9] - The strategy includes prioritizing indications with high unmet needs and substantial commercial potential [11] Product Pipeline - **Lead Asset**: Budo (anti-CD19 monoclonal antibody) - Targeting CD19 is seen as optimal due to its expression across various B-cell stages and its ability to deplete auto-reactive B-cells [13][14] - Budo is differentiated from existing CD19 therapies by its high affinity and potential for subcutaneous administration [15][16] - **Second Asset**: CLYM116 (anti-APRIL antibody) - Unique mechanism of action that degrades APRIL, potentially leading to increased efficacy and reduced treatment burden [46] Clinical Development Insights - Budo is currently under investigation for primary membranous nephropathy (PMN) and immune thrombocytopenia (ITP) [29][42] - Early data from PMN trials showed promising results with complete B-cell depletion and significant proteinuria reduction [34] - The company plans to initiate a phase 2 study for Budo in the second half of 2025, guided by insights from the phase 1b study [36][40] Market Opportunity - There is a significant unmet need in PMN, with no approved therapies currently available, presenting a substantial market opportunity [31] - Climb Bio is also exploring indications in IgE-mediated diseases, single organ autoimmunity, and complex systemic diseases, with a focus on lupus [24][27] Biomarker Strategy - Biomarkers are central to Climb Bio's development strategy, particularly B-cell depletion and autoantibody reductions, which are expected to correlate with clinical outcomes [22][23] Future Outlook - Key value-creating accomplishments anticipated over the next year include successful execution of clinical studies, differentiation of their products, and strategic indication selection [48] Additional Important Content - The company was formed through a shell company acquisition, which has implications for its market positioning and investor awareness [5] - The leadership team has extensive experience in both large pharma and biotech, enhancing the company's strategic capabilities [2][3] This summary encapsulates the critical insights and strategic direction of Climb Bio as discussed during the conference call, highlighting its innovative approach to addressing unmet medical needs in the field of immunology.
