Go­ing all in: Bio­gen com­mits an ex­tra $500M to Alzheimer’s block­buster hope­ful ad­u­canum­ab

Bio­gen CEO Michel Vounatsos is go­ing all in on his late-stage Alzheimer’s drug ad­u­canum­ab.

The big biotech said to­day that it paid Neurim­mune, which out-li­censed the drug to Bio­gen, $150 mil­lion to cut its ne­go­ti­at­ed roy­al­ty rate for post-ap­proval sales by 15%. And it’s pre­pared to pay an­oth­er $50 mil­lion for an­oth­er 5% rate re­duc­tion.

The $200 mil­lion deal comes on top of yes­ter­day’s an­nounced plan to re­struc­ture Bio­gen’s part­ner­ship with Ei­sai on ad­u­canum­ab, which one promi­nent an­a­lyst ex­pects will cost Bio­gen about $300 mil­lion in added re­search costs.
