Microbubbles
Microbubbles is a Small molecule drug developed by University of Nebraska. It is currently in Phase 1 development. Also known as: DEFINITY® (Perflutren Lipid Microsphere) manufactured by Lantheus Medical Imaging, OPTISON™ (Perflutren Protein-Type A Microspheres Injectable Suspension, USP) manufactured by General Electric Global Research.
Microbubbles are bubbles smaller than one hundredth of a millimeter in diameter, used in various applications including industry, medicine, and life science. In medical research, microbubbles have been studied as a potential tool for diagnostic imaging and treatment of conditions such as ductal carcinoma in-situ and diffuse intrinsic pontine glioma.

Hover any row for the lag rationale. Lag estimates are reduced when the drug has FDA Breakthrough or EMA PRIME designation (sponsors file globally in parallel).
Estimate based on the BIO/Informa industry phase transition rates plus per-drug modifiers for therapeutic area, sponsor type, FDA designations, mechanism, and trial design. Per-jurisdiction lags from Tufts CSDD international approval studies. Not investment, clinical or regulatory advice. Methodology: /methodology#likelihood.
