Life According to Sam provides insight into the life of Sampson “Sam” Berns and his family. At the beginning of the film, Sam states, “I want you to know me.” Accordingly, the film alternates between highlighting Sam’s experiences as he navigates life as a teenage boy and his participation in the first ever clinical trial for progeria.  At the start of the film, Sam is a 13-year-old boy in middle school. As with many other boys his age, his interests include Legos, music, and spending time with his friends, or his “bros” as he affectionately calls them.  

But Sam was diagnosed with progeria just prior to his second birthday. Progeria is a rare disease that affects approximately 250 children worldwide, caused by a genetic mutation which codes for the formation of an abnormal toxic protein, protegrin, that builds up in organs over time. It is a premature aging syndrome that causes progressive cardiovascular decline and for which there is no cure. The average age of death for these children is 13, and they die primarily of heart attacks and strokes.  

At the time of Sam’s birth his mother Leslie was a pediatric intern and his father, Scott, a pediatric emergency medicine physician. After his diagnosis, the family devoted themselves to progeria, an orphan disease which at the time had no identified genetic etiology, no foundation, no research, and no treatment. With the help of Leslie’s sister Audrey, the family started The Progeria Research Foundation, which raised over $1.25 million dollars, funded the discovery of the gene for progeria, and began the first clinical trials to test treatment for the disease. 

In the film, Leslie spearheads the first ever clinical trial for the treatment of progeria. The drug, lonafarnib, had demonstrated efficacy in mice and was FDA approved for a clinical trial including 28 children from 16 countries. The children would receive the medication for 2.5 years and return to Boston Children’s Hospital three times per year for a battery of tests. At the end of the trial, Leslie goes through the arduous process of writing up the results and submitting the trial for publication in hopes of making the drug more widely available for children with progeria. In the end, the trial results are published and the results for individual patients are released. While the medication falls short of being a cure, there are glimpses of hope in patients whose disease progression has been slowed or even reversed.
