Executive Summary
The July 24, 2026 orphan drug approval stream contained a single label expansion for SIROLIMUS (SCOMARA) by AFT PHARMACEUTICALS LTD, classified as a fallback approval with a moderately bullish signal. There were no NMEs or biosimilars approved, limiting the period's investment impact to a narrow, sponsor-specific event.
