Key business updates and strategy

  • Plans to separate the royalty management and biopharma operations into two independent businesses in 2026, with the royalty business retaining Jemperli and Imsidolimab rights and the biopharma business focusing on ANB033 and Rosnilimab.

  • Royalty business expected to be cash flow positive by Q2 2027 after paying off Sagard debt, with potential for dividends or share repurchases.

  • Biopharma operations will be spun out with at least two years of cash, anchored by ANB033, and designed for resilience and independence from royalty business outcomes.

  • Ongoing litigation with GSK over Jemperli CRE obligations, with an expedited trial expected by summer and no operational impact on the planned separation.

  • Stock price has doubled since the separation announcement, with management seeing further upside in both businesses post-separation.

Pipeline and clinical development

  • ANB033, a CD122 antagonist, is in a phase 1B trial for celiac disease with data expected in Q4 next year; a second trial in EOE is planned for 2026.

  • Rosnilimab showed positive phase 2b results in rheumatoid arthritis, with plans for phase 3 development in 2026, pending strategic or external funding.

  • Ulcerative colitis trial for Rosnilimab showed good safety and pharmacodynamics but insufficient efficacy, informing future RA trial design.

  • Phase 2b RA data showed rapid and sustained low disease activity and remission rates, with efficacy across prior therapies and strong safety profile.

  • ANB033 program aims to address a large, underserved celiac population, with potential for orphan-like pricing and expansion into additional indications.

Financial outlook and operational planning

  • Projected year-end cash of $300 million, including a $75 million milestone from GSK as Jemperli surpasses $1 billion in sales.

  • Biopharma spinout will be capitalized for at least two years of operations, with flexibility to run early studies and enhance partnering value.

  • Royalty business will minimize infrastructure and focus on returning value to shareholders through dividends or buybacks.

  • Multiple clinical readouts for Jemperli in new indications expected over the next two years, supporting ongoing royalty growth.

  • Strategic capital will be sought for late-stage Rosnilimab development, with a Q1 FDA meeting to inform phase 3 design.

One of the very few apps you could call perfect. If something was to add to it, maybe the share price of the company when you search for it, but it's already excellent.
