The Big 3

1
Relation Therapeutics, Deerfield Management form new companies
  • Relation Therapeutics and Deerfield Management are collaborating to form new companies based on discovered drug targets. This strategic partnership aims to advance novel therapeutics.
  • Why it matters: This is a capital-structure story as much as a science story: forming multiple target-led newcos can “warehouse” optionality, attract specialist funding per asset, and create cleaner value-realization paths than keeping everything inside one platform.

Jazz, Zymeworks highlight late-stage HER2 bispecific results
  • Jazz Pharmaceuticals and Zymeworks have highlighted positive late-stage results for their HER2 bispecific drug, Ziihera.
  • Why it matters: Late-stage readouts are where narratives become models: if this supports broader use, it can expand the commercial footprint and strengthen positioning against entrenched HER2 standards — translating “good data” into real pricing power and durable demand.

J&J lupus candidate Imaavy advances to late-stage after P2 success
  • Johnson & Johnson's lupus candidate, Imaavy, is moving towards late-stage development following successful Phase 2 results.
  • Why it matters: The Phase 2 → late-stage step is a de-risking gate: once a program commits to pivotal development, timelines, trial design, and spend become the key variables — and the asset starts to carry materially more probability-weighted value inside the pipeline.
