FDA said no. We got them to yes in 90 days.
The Result
FDA granted Breakthrough Device Designation for Diastolytix on October 9, 2024.
The Device
Diastolytix screens for Grade 3 diastolic dysfunction using standard ECGs, replacing the need for echocardiography. Millions go undiagnosed because echo requires skilled sonographers and cardiologists with advanced training.
The Challenge
Carelog came to Innolitics confident their device met FDA criteria for Breakthrough Device Designation. Innolitics prepared and submitted the request.
FDA pushed back, questioning whether Diastolytix truly met the "more effective treatment or diagnosis" standard.
What Innolitics Did
The team didn't accept no. Within days:
- Repositioned the value proposition: Shifted from competing with echocardiography to serving patients who'd otherwise get no diagnosis at all. Flipped FDA's objection into a strength.
- Quantified the gap: Data-mined ICD codes for asymptomatic heart failure and located NIH research showing rural ultrasound access disparities.
- Framed for health equity: Emphasized that Diastolytix uses commonly available ECG devices, benefiting underserved populations impacted by healthcare disparities. Differentiated from Ultromics' EchoGo (which requires echo images) by positioning as a complementary frontline screening tool.
