Johnson County Clintrials LLC

Johnson County Clintrials LLC, a for-profit limited liability company based in Lenexa, Kansas, operates exclusively as a subcontractor providing Phase 1 clinical trial services for filovirus vaccine development programs. The vendor holds no prime federal contracts; all four recent federal awards are subcontracts under International Aids Vaccine Initiative Inc., performing work funded by the Department of Health and Human Services Office of the Assistant Secretary for Preparedness and Response.

Johnson County Clintrials' entire award footprint centers on a single customer — HHS ASPR — and a narrow clinical research scope. Three of four recent subcontract awards, totaling combined dollars obligated of $3.3 million, support Phase 1 clinical trials for monovalent vaccines targeting Marburg virus and Sudan Ebolavirus, based on recombinant expression of filovirus glycoproteins. Work is performed under two parent vehicles: the Pandemic Influenza Preparedness and Response 2012-2016 vehicle and the Medical Countermeasures Clinical Studies Network. Awards cluster in biotechnology R&D (three awards under NAICS 541714 — Research and Development in Biotechnology except Nanobiotechnology — and one under NAICS 541710). The most recent subcontract award dates to July 2026, with a prior award in March 2026 and February 2026.

Activity volume is sparse in the source data: one award in 2018, then a three-award pulse in 2026. Johnson County Clintrials operates in a narrow, specialized niche — Phase 1 clinical trial execution for high-consequence pathogen vaccines — rather than a broad service or product portfolio. The vendor's footprint signals deep technical capability in clinical trial site operations and filovirus vaccine development pathways, but customer and program concentration is absolute; all revenue derives from a single HHS ASPR-funded initiative executed through a single prime relationship.
