Key February 2026 Events

VNDA Bysanti — Approved Feb 20 (ODIN TIER_1)

Vanda Pharmaceuticals' Bysanti (milsaperidone) was approved one day ahead of its PDUFA date for schizophrenia and bipolar-I disorder. This first-in-class M4 receptor partial agonist received strong ODIN scoring based on robust Phase 3 data, Priority Review designation, and an unmet need in psychiatry. VNDA surged +44% in after-hours trading. Full analysis →

RGNX RGX-121 — CRL Issued Feb 9 (ODIN TIER_3)

RegenXBio's gene therapy for MPS II (Hunter Syndrome) received a Complete Response Letter. ODIN had scored this TIER_3 (mixed odds) citing manufacturing complexity and a limited efficacy dataset. The CRL highlights the challenge of gene therapy regulatory pathways.

REGN Dupixent — Feb 28 (ODIN TIER_1)

Regeneron's supplemental BLA for Dupixent (dupilumab) in allergic fungal rhinosinusitis. As an sBLA expansion of an already-approved blockbuster franchise, this carries lower regulatory risk. ODIN scores it TIER_1.

ASND Navepegritide — Feb 28 (ODIN TIER_1)

Ascendis Pharma's TransCon CNP (navepegritide) for achondroplasia. A first-in-class C-type natriuretic peptide therapy targeting the root cause of the most common form of dwarfism.
