Varda Space and United Therapeutics Partner on Microgravity Drug Formulation

Varda Space Industries and United Therapeutics have announced a collaboration to explore microgravity-based drug formulation for rare pulmonary diseases, according to a press release.

The companies will conduct pharmaceutical processing aboard Varda's orbital manufacturing and reentry platform during multiple missions to low Earth orbit. The work will focus on how microgravity affects the structure and crystallization of small molecule medicines, with the goal of improving drug stability, bioavailability, and delivery characteristics.

Initial experiments will involve compounds used in treatments for life-threatening pulmonary conditions. Varda's system launches pharmaceutical payloads to orbit, processes materials in microgravity, and returns the finished products to Earth using its W-series reentry capsules.

The collaboration brings together Varda's orbital manufacturing capabilities and United Therapeutics' expertise in drug development to investigate how space-based processing can produce formulations not achievable under terrestrial conditions.
