Harper, M.D., executive vice president at Amgen, stated, “The intersection of immunology and oncology represents one of the most promising approaches to delivering significant impact for patients with cancer.

Separately on January 5th, analyst Cory Kasimov of J.P. Morgan reiterated a Neutral rating on Amgen with a price target of $163. Kasimov noted, “Given [Amgen’s] capital allocation strategy, we believe AMGN offers investors a differentiated investment opportunity vs. other biotechs, which likely contributed to its outperformance in 2014.” He continued, “At this point, however, we believe the near-term potential of new drugs… is largely appreciated by investors… We do believe that recent cost cutting will help the bottom line, and the [company’s] position as the only dividend-issuing biotech should continue to attract generalist interest.” Kasimov concluded, “Bottom line, we believe AMGN’s pipeline and future business mix… are attractive, but with shares meaningfully higher in 2014… we have a hard time finding additional near-term levers for relative upside. Thus, we are maintaining a Neutral rating, but increasing our YE15 PT to $163 from $130.”
