Verdict history (8 calls)

Every verdict Biotech Distilled has published on Climb Bio, oldest first — the full history, never a selection. How calls are scored: the track record.

  1. Watch Climb Bio (CLYM) - Scientific Deep Dive for Budoprutug and Pipeline Products Intriguing antibody engineering with early biological validation, but a leaky patent moat, active IP litigation, and late-to-market position make this a clinical data trade rather than a buy-and-hold investment.
  2. Speculative buy speculative UPDATE: Climb Bio (CLYM) - The Smart Money Doubles Down A $110M at-market PIPE led by a roster of healthcare-specialist funds (RA Capital, Adage, Cormorant, Redmile, et al.) provides a meaningful Bayesian update on the molecule's diligence and closes the dilution gap well past H2 2026 data readouts.
  3. Buy core UPDATE: Climb Bio (CLYM) - The SC Wedge Lands SC budoprutug matches IV at ~80% B-cell depletion in healthy volunteers, proving the commercial wedge is real, while the catalyst calendar compressed to a June ITP readout six weeks out.
  4. Buy core UPDATE: Climb Bio (CLYM) - The Sweeper Clears Its First Bar CLYM116 cleared safety through 320 mg in 49 healthy volunteers with zero SAEs/DLTs, removing the most binary failure mode for the novel sweeper mechanism, while the June ITP patient readout remains the next key binary.
  5. Buy core UPDATE: Climb Bio (CLYM) - The ITP Bar Clears Budoprutug delivered >90% B-cell depletion and +111K platelet rise at 24 weeks in heavily pretreated ITP patients, with 3 of 4 rituximab-failures responding, providing independent clinical validation of the CD19-over-CD20 thesis.
  6. Buy core UPDATE: Climb Bio (CLYM) - The Sweeper Gets a Date CLYM116 PK/PD reveal pinned to September 3, Mabworks deal deepened at unchanged economics, and a dense Q4 catalyst cluster is fully funded; holding through the catalyst cluster remains defensible while trimming into the +28% run is also noted as reasonable.
  7. Buy core UPDATE: Climb Bio (CLYM) - The Sweeper Delivers Its Number CLYM116 posted a ~29-day half-life (~3x sibeprenlimab) with >90% free APRIL suppression and 60-75% IgA knockdown through 12 weeks off a single dose, converting the dosing-frequency wedge from modeled to measured; PrisMN replication remains the Q4 lead-asset valuation event.
  8. Hold UPDATE: Climb Bio (CLYM) - The Leaky Sieve PrisMN 200 mg cohort showed incomplete B-cell depletion (74% vs. 100% in Phase 1b) due to 2x faster drug clearance in proteinuric patients, deferring complete-remission data to 2027 just as obinutuzumab nears approval; mechanism is intact but the right dose is undecided and the lead-asset payoff is delayed.
