Eye­ing a multi­bil­lion-dol­lar mar­ket, Shire snags pre­clin­i­cal IVIg ri­val from AB Bio­sciences

Shire $SH­PG is get­ting in ear­ly on an in­ves­ti­ga­tion­al prod­uct that might one day re­place IV in­fu­sions of con­cen­trat­ed an­ti­bod­ies giv­en to pa­tients to boost their im­mune sys­tems. The move could get Shire’s foot in the door of a multi­bil­lion-dol­lar mar­ket.

These an­ti­body cock­tails, made from the plas­ma of thou­sands of blood donors, are of­ten giv­en to pa­tients whose im­mune sys­tems don’t make enough an­ti­bod­ies to fight germs that cause in­fec­tions. The ther­a­pies, called in­tra­venous im­muno­glo­bin or IVIg, are part of a mar­ket that’s pro­ject­ed to be worth $10.9 bil­lion by 2022. But IVIg ther­a­pies are cum­ber­some to make and re­quire vis­its to clin­ics or hos­pi­tals for pa­tients to get treat­ment.
