Biopharmaceutical Uniform Crystallization Test Bed

Pharmaceuticals in general, and biopharmaceuticals specifically, are often best formulated as microscopic crystals.nbsp; The crystalline state is most stable, allows a high-concentration, low-viscosity parenteral formulation, and facilitates alternate routes of administration. There is a requirement that the crystals be small, a few micrometers or less, and uniform, the same size within a few per cent.nbsp; The problem: most recombinant protein biopharmaceuticals do not crystallize uniformly.nbsp; A solution to this problem has been discovered in on-orbit crystallization experiments, which produced very uniform sized crystals. Manufacturers are creating demand for on-orbit testing of uniform crystallization protocols, but suitable hardware and ISS research opportunities are inadequate.nbsp; Techshot proposes a business plan in which cost and time saving versatile flight hardware and flexible flight opportunities are made openly available to corporate and institutional users seeking improvements or refinements in product purification, formulation and/or delivery.nbsp; Hardware and flight plans on ISS will be offered in which factorial and/or real-time photography experiments can be performed on the basis of Techshotrsquo;s regular ISS access and versatile hardware fleet.nbsp; In Phase I research Techshot will (1) adapt up to four different existing hardware modules for this specific application, (2) test these modules in model protein crystallization experiments in the laboratory, and (3) perform mathematical modeling for a ground-based crystallization reactor with adjustable parameters for approximating the relevant low-gravity physics.nbsp; In Phase II research Techshot will prepare the hardware modules for flight readiness, prepare an aggressive ISS use plan, and construct and operate an optimizable ground-based reactor.nbsp; The intended outcome is a business paradigm for hastening the availability of stable biopharmaceuticals with favorable options for delivery.
