Abstract: The invention provides methods for producing crystalline an anti-PD-1 monoclonal antibody (mAb), wherein the mAb is pembrolizumab or a pembrolizumab variant, comprising (1) mixing a solution comprising (a) the mAb, (b) polyethylene glycol (PEG), and (c) an additive selected from the group consisting of: caffeine, theophylline, 2? deoxyguanosine-5?-monophosphate, a bioactive gibberellin, and a pharmaceutically acceptable salt of said bioactive gibberellin, to form a crystallization solution, (2) incubating the crystallization solution for a period of time sufficient for crystal formation; and (3) optionally harvesting the crystalline anti-PD-1 mAb from the solution. In specific embodiments, the PEG is PEG 3350 and the additive is caffeine. The invention also relates to the novel anti-human PD-1 mAb crystals produced by the methods described herein.

Abstract: Crystals of pembrolizumab and structurally similar anti-PD-1 monoclonal antibodies are provided, as well as methods of producing such crystals, and uses of compositions comprising such antibody crystals, e.g. in treatment of cancers. The present invention satisfies these needs and more by providing pembrolizumab crystals and a method producing pembrolizumab crystals. One embodiment of the method of the invention produces crystals suitable for X-ray diffraction, and the inventors herein used such crystals to solve the three-dimensional structure of pembrolizumab to 2.3 A resolution.
