Affinity Therapeutics is developing drug-coated vascular grafts and drug-eluting wraps to reduce stenosis rates and failure in hemodialysis patients. They interviewed 128 potential customers including nephrologists, surgeons, and patients, and identified two minimum viable products - a coated graft and a drug-eluting wrap that could be used with fistulas or grafts. Based on further interviews and analysis, they determined the wrap has potential for a larger market. Affinity plans to submit a Phase II SBIR grant to further develop the wrap MVP and continue cultivating relationships with key opinion leaders and medical centers.
