Anti-Synthetase Syndrome is uncontested. Cartesian Therapeutics (RNAC) is the only US-listed developer in the $100M to $20B band running a clinical programme here, with Descartes-08 in phase 2.

Nothing here has reached Phase 3: 1 programme in mid stage and 0 in early stage, so the field is still several years from a first approval.

$69M of allocated capital sits in Anti-Synthetase Syndrome, ranking it 282nd of 299 indications by the money committed to it.

How this page is built

  • Universe is US-listed drug developers with a $100M to $20B market capitalisation, identified by SEC SIC code 2833, 2834 or 2836 or by a pharmaceutical or biotechnology industry classification, less a reviewed exclusion list of contract research organisations, device and diagnostics makers and diversified generics manufacturers.
  • An asset attributed to three or more different companies is treated as shared standard of care rather than any one company’s programme and excluded. Pembrolizumab alone appears under 21 tickers in raw trial data.
  • A programme counts only where at least one industry-sponsored trial supports it, so investigator-initiated academic studies of third-party drugs are excluded.

Allocated capital divides each company’s market capitalisation evenly across the indications it is running clinical programmes in, so every dollar of the universe is counted exactly once. Total market capitalisation competing counts a company in each of its indications and therefore sums to more than the universe.

Third-party market size estimates are not used anywhere on this page. Approved incumbents are excluded from competitor counts, and companies above $20B are outside the universe by construction.
