  8. 8. 6 Amgen 2011 Annual Report The Next Wave: A Look Inside Amgen’s New Drug Pipeline Amgen’s pursuit of pioneering science has always been driven by the goal of providing truly novel therapies for patients with serious illnesses. We believe that a deep understanding of human biology is the key to helping patients with needs that lie beyond the reach of current therapies. This science-based approach has given Amgen by blocking PCSK9. In a phase 1 study, a single density (BMD), AMG 785 significantly increased highly innovative products, and it also accounts for dose of AMG 145 lowered LDL levels by 64 percent BMD at the lumbar spine. It is also being studied the breadth of potential first-in-class therapeutics for approximately one month. Amgen has started in fracture healing. in our pipeline. a large phase 2 program to evaluate AMG 145 as both a stand-alone agent and a combination Turning a Virus from an Enemy into an Ally Notable examples include AMG 145, a novel therapy with statins. One major goal is to investigate Talimogene laherparepvec is a cancer cholesterol-lowering agent that could redefine whether PCSK9 inhibition can work synergistically immunotherapy, a new modality for targeting treatment targets in high-risk patients; AMG 785 with statins to achieve reductions in LDL that are solid tumors and their metastases.

I saw a rheumatologist and got diagnosed with psoriatic arthritis. I was lucky to find out it was very treatable.” Phil’s treatment program includes Enbrel® (etanercept), which has helped improve his overall health so he can return to the things that matter most to him. But remembering the uncertainty he faced when his symptoms first struck, he decided to tell about his experience. “I want to motivate and empower others with chronic inflammatory joint and skin conditions to take action,” Phil says. In partnership with Amgen and Pfizer, Phil launched On Course with Phil, a disease education website, which also features Be Joint Smart, a new educational effort sponsored by the Arthritis Foundation and the National Psoriasis Foundation.
  11. 11. Amgen 2011 Annual Report 9Judy —XGEVA® (denosumab)Judy remembers just how devastating it was to find out that her lung cancer had returned and had spread to herbones— and to learn about debilitating skeletal consequences such as fractures. That was more than two yearsago. Today, Judy’s outlook on life is more upbeat. “Cancer doesn’t define me,” says Judy (shown here with hergrandchildren). “I have a lot of optimism, and I feel like I’m making great progress.” Judy now tries to look atcancer as a disease she can manage with her doctor’s help. “My doctor had been talking about XGEVA® for a longtime, and he said I could go on it as soon as it was approved” for the prevention of skeletal-related events frombone metastases. “I’m so grateful for all the support from my family and my medical team.” Bill — Neulasta® (pegfilgrastim) As general sales manager of a Los Angeles radio station, Bill set the ambitious goal of staying on the job while he battled lymphoma. “My doctors made a point of telling me I’d get Neulasta® the day after each chemotherapy session,” says Bill. “They said it was a vital part of my treatment because it could help increase the white blood cells killed off by the chemo.” Bill managed to avoid getting an infection during his chemotherapy treatment.Dora — Prolia® (denosumab)A retired laboratory assistant from West Sussex, United Kingdom, Dora, now 78, was first diagnosed with postmenopausalosteoporosis in 1998, as the result of a routine scan for osteoporosis. Prior to her diagnosis, Dora had already been aware ofosteoporosis because both her mother and grandmother had suffered from it. “My mother’s was particularly bad,” Dora says. “Shebecame doubled over and suffered from a restricted airway as a result. She then fractured her hip and died in hospital shortly after.”Dora is currently receiving twice-yearly injections with Prolia®. She had previously taken bisphosphonates but could not tolerate them.“I have five grandchildren and two great-grandchildren to keep up with, so it’s important to me to help keep my bones strong.” Elena — Mimpara® (cinacalcet) Elena, a piano teacher from Elektrostal, a small town in Russia east of Moscow, has had type 1 diabetes since she was 11. She has lost a leg to the disease and has been on dialysis for many years due to declining kidney function. Her kidney disease led to osteodystrophy (defective formation of the bone), which left her with hand deformities and pain that prevented her from teaching. In 2010, Elena’s physician prescribed Mimpara® to help balance her levels of parathyroid hormone, calcium, and phosphorus. With the help of her mother—her closest friend—Elena strives to remain active and enthusiastic. She has also resumed giving piano lessons to children. Her optimism in the face of serious health problems is an inspiration to her doctors and other patients.Rodney — Enbrel® (etanercept)Before rheumatoid arthritis (RA) attacked his joints, Rodney had been an extremely fit amateur athlete. As his RA progressed, hewent from running and exercising regularly to walking with a cane on his bad days. “I had never experienced pain like that before,”Rodney says. After trying several treatments that didn’t work for him, Rodney’s doctor prescribed ENBREL. “I noticed my energycoming back,” recalls Rodney. “That’s when I thought, ‘I can start running again!’” Slowly but steadily, he regained his stamina.“I’m not the fastest runner, but I’m enjoying the activity. I really feel good about where I’m at now.”
