Meet Joe - PNH Patient

Meet Joe - Diagnosed with PNH at 24 Years Old

Joe was completing his Master’s degree, engaged to be married, and on his way to becoming a professional mixed martial arts competitor when the symptoms began: unexplained fatigue, dark urine, back and stomach pain. After six weeks of numerous blood tests, Joe was referred to a hematologist who diagnosed him with paroxysmal nocturnal hemoglobinuria (PNH) – an ultra-rare, life-threatening blood disorder in which uncontrolled activation of the complement system leads to the chronic destruction of red blood cells. Historically, approximately one-third of patients with PNH do not survive more than five years from the time of diagnosis.

When Joe was diagnosed, he says that he felt like his dreams were nearly shattered. He was worried that he would not have a future with his fiancée and was told he would never be able to compete in contact sports again. With this news, Joe could have simply thrown in the towel, but he didn’t. Instead, he made it his mission to educate himself and his family about PNH. Fortunately for Joe, his doctors were able to manage his PNH.

“I’ve never been one to back down in a fight, but when I was diagnosed with PNH, the prognosis was overwhelming. I had no choice but to view this disease as yet another challenge – one that I had to overcome. If anything, living with PNH has made me appreciate my time even more, and given me more drive to get back to doing what I love to do.”

Today, Joe shares his story with other patients with PNH to give them hope for the future. Joe is living his life on his own terms; he married his college sweetheart, welcomed the birth of two daughters, and is back in his routine. 

Meet Evie - Diagnosed wiht HPP at 2 Weeks Old

When an ultrasound revealed that Evie had extremely fragile and transparent bones, doctors told expectant parents John and Lindsey that it was not likely their baby girl would live long after birth. The hours that Evie’s parents expected to have with her turned into weeks, but the baby was gripped by seizures. Then, a routine blood draw revealed that Evie had low alkaline phosphatase (ALP), which enabled them to diagnose her with hypophosphatasia (HPP) – an ultra-rare, genetic, life-threatening metabolic condition that prevents minerals such as calcium and phosphate from being properly deposited in bones.

Her parents were told that Evie’s case was very severe and that there were no approved or effective treatment options. At three months old, Evie was enrolled in a clinical trial to receive an investigational targeted enzyme replacement therapy, and she continues to receive the investigational therapy today.

Evie is, as her mother says, “writing the book on where we go from here. Her story gives other parents with special needs kids hope that they can be okay, and things can be good.”

    I have been working at Alexion Pharmaceuticals full-time (Less than a year)


    Alexion is a good company. I currently work at
    The ARIMF location and have been for about a year. I've encountered such smart, talented and experienced individuals in my time here and have learned more in one year than I have in most of my time in the industry thus far. The company is experiencing many changes lately; however, in the long run, I think it will be good for it especially ARIMF. The culture is changing and we finally have good leaders and a new plant manager that are truly committed in changing the culture for the better. As for benefits and pay, Alexion offers the full package and more. I recently made the move out of Cambridge and am very happy to have found a renown company so close to home. The employees here are very hard workers and are truly committed to making a difference every day.


    Many of the reviews on here are negative towards management but I honestly believe that the perspective on management truly depends on what part of the business you report to. So far, my management has been really great; some people may have different experiences which I respect but I have had a great one in that regard. In every industry and every company, you will find terrible managers but that is more of a culture and behavioral issue than a widespread business one.
    The environment is fast paced and yes, there are times where you will have to work more than 40 hours when working on certain projects and deadlines but that is not the requirement. I think management is getting better about acknowledging that (especially with the culture change) and employees themselves are feeling less like they have to be constantly chained to a laptop. The plant manager has reinforced this: ask for help and push back when you feel overwhelmed. This is a passionate company where you need to hit the ground running and not twiddle your thumbs. In biotech, the expectation is that you may have to work more and harder at times (I've always had to do this everywhere I've worked); it's the nature of the business but in the end it comes out in the wash. Alexion is not some sweat shop working their employees to the core as some reviews state. With the CEO cleaning house and bringing in a global culture change, I think the company is headed in the right direction.

    Advice to Management

    Keep focusing on culture. Reinforcing it, welcoming it and truly implementing it. A change of direction is needed, not working harder in the same direction. Get people to think more about "emotional intelligence" and how that concept can really drive change, passion and behavior.

    Average Interview


    I applied through other source. The process took 5 weeks. I interviewed at Alexion Pharmaceuticals (New Haven, CT) in October 2017.


    Internal candidate - phone interview followed by five separate thirty minute interviews (varying levels within the department) spread out between two days. Two weeks after the interviews the HR recruiter informed me they would let me know by COB that week. However, I never heard. Turns out the HR recruiter was let go and no one seemed to pick up their work. Still have never actually been told I didn't get the position.
