I would suspect by the time the program truly became "first line" and superseded Revlimd, Celgene would welcome the shift into a program with a longer patent expiration date.
P.S. Considering the BLUE program is for r/r multiple myeloma I don't think this will be an issue.
daratumumab is already going to crush revlimid. by the time the blue drug makes (or if) it to market (5-6yrs), revlimid will be well on its way down. but it may still ahve some market for failure pts
The transaction expands Celgene’s Inflammation and Immunology pipeline through the acquisition of Delinia’s lead program, DEL106, as well as related second generation programs. DEL106 is a novel IL-2 mutein Fc fusion protein designed to preferentially upregulate regulatory T cells (Tregs), immune cells that are critical to maintaining natural self-tolerance and immune system homeostasis. Augmenting Tregs as a means of restoring immune system balance has the potential to benefit patients with a variety of autoimmune diseases such as systemic lupus erythematosus and rheumatoid arthritis.
