A vial access device includes a housing having first and second connectors. The first connector is configured to be secured to a first container and the second connector is configured to be secured to a second container. The vial access device further includes a spike member extending from the housing and having a proximal end and a distal end. The spike member defines a vent lumen and a fluid lumen spaced from the vent lumen with each of the vent lumen and the fluid lumen having a distal opening. A shape defined by a circumference of the spike member is only symmetric about one axis at a position between the proximal end of the spike member and the distal opening of the fluid lumen.

1. A vial access device comprising: a housing having first and second connectors, the first connector configured to be secured to a first container, the second connector configured to be secured to a second container;a spike member extending from the housing and having a proximal end and a distal end, the spike member defining a vent lumen and a fluid lumen spaced from the vent lumen, each of the vent lumen and the fluid lumen having a distal opening, wherein a shape defined by a circumference of the spike member is only symmetric about one axis at a position between the proximal end of the spike member and the distal opening of the fluid lumen, wherein the circumference of the spike member varies in size and shape between the proximal end of the spike member and the distal opening of the fluid lumen. 2. The vial access device of claim 1, wherein the circumference of the spike member is substantially oval-shaped. 3. The vial access device of claim 1, wherein the distal openings of the vent lumen and the fluid lumen are each defined by a top edge and a bottom edge spaced axially from the top edge, outer portions of the top edges of the vent lumen and the fluid lumen are smooth and configured to substantially prevent coring of a stopper when penetrating the stopper with the spike member. 4. The vial access device of claim 3, wherein the top edges of the vent lumen and the fluid lumen are chamfered. 5. The vial access device of claim 1, wherein the spike member comprises a ring extending radially outward from the spike member, wherein the ring is configured to engage a portion of a stopper upon penetrating the stopper with the spike member, and wherein a circumference of a portion of the spike member that is positioned distally of the ring is larger than a circumference of a portion of the spike member that is positioned adjacent to the distal openings of the vent and fluid lumens. 6. The vial access device of claim 1, wherein the distal opening of the vent lumen is axially spaced from the distal opening of the fluid lumen, the vent lumen positioned closer to the distal end of the spike member than the fluid lumen. 7. The vial access device of claim 1, wherein the distal end of the spike member is pointed and configured to pierce a stopper. 8. The vial access device of claim 7, wherein the distal opening of the fluid lumen extends in a longitudinal direction of the spike member. 9. The vial access device of claim 1, further comprising a lubricant coating positioned on the spike member. 10. The vial access device of claim 9, wherein the lubricant coating is positioned adjacent to the distal end of the spike member. 11. The vial access device of claim 1, further comprising a pressure equalization chamber in fluid communication with the vent lumen. 12. The vial access device of claim 1, further comprising a pierceable membrane positioned adjacent to the first connector, the pierceable membrane covering a proximal opening of the fluid lumen. 13. The vial access device of claim 1, wherein the first connector comprises a neck portion of the housing defining an opening that is configured to receive a corresponding connector of a syringe adapter. 14. The vial access device of claim 1, wherein the second connector comprises a plurality of hook elements configured to engage a medical vial and secure the vial access device to the medical vial. 15. The vial access device of claim 1, wherein a cross-section transverse to a longitudinal axis of the spike member includes a y-axis and an x-axis, wherein a dimension of the spike member along the x-axis adjacent to the fluid lumen is larger than a dimension of the spike member along the x-axis adjacent to the vent lumen. 16. A vial access device comprising: a housing having first and second connectors, the first connector configured to be secured to a first container, the second connector configured to be secured to a second container;a spike member extending from the housing and having a proximal end and a distal end, the spike member defining a vent lumen and a fluid lumen spaced from the vent lumen, each of the vent lumen and the fluid lumen having a distal opening, wherein the distal openings of the vent lumen and the fluid lumen are each defined by a top edge and a bottom edge spaced axially from the top edge, wherein the spike member comprises a ring spaced and extending radially outward from the circumference of the spike member, and wherein the ring is configured to rest within a seal of the second container upon insertion of the spike member into the second container. 17. The vial access device of claim 16, wherein an outer portion of the top edges of the vent lumen and the fluid lumen are smooth and configured to substantially prevent coring of a stopper when penetrating the stopper with the spike member, and wherein the top edges of the vent lumen and the fluid lumen are chamfered. 18. The vial access device of claim 16, wherein the distal opening of the vent lumen is axially spaced from the distal opening of the fluid lumen, the vent lumen positioned closer to the distal end of the spike member than the fluid lumen. 19. The vial access device of claim 18, wherein the distal end of the spike member is pointed and configured to pierce a stopper, and wherein the distal opening of the fluid lumen extends in a longitudinal direction of the spike member. 20. A drug transfer system comprising: a syringe adapter configured to be secured to a first container;a vial access device comprising: a housing having first and second connectors, the first connector configured to be secured to the syringe adapter, the second connector configured to be secured to a second container;a spike member extending from the housing and having a proximal end and a distal end, the spike member defining a vent lumen and a fluid lumen spaced from the vent lumen, each of the vent lumen and the fluid lumen having a distal opening, wherein a shape defined by a circumference of the spike member is only symmetric about one axis at a position between the proximal end of the spike member and the distal opening of the fluid lumen, wherein the circumference of the spike member varies in size and shape between the proximal end of the spike member and the distal opening of the fluid lumen. 21. The drug transfer system of claim 20, wherein the spike member comprises a ring extending radially outward from the spike member, wherein the ring is configured to engage a portion of a stopper upon penetrating the stopper with the spike member, and wherein a circumference of a portion of the spike member that is positioned distally of the ring is larger than a circumference of a portion of the spike member that is positioned adjacent to the distal openings of the vent and fluid lumens.
