UCLA Grad Cured of Sickle Cell with New Gene Therapy

A new UCLA graduate who once couldn't play with other kids without risking hospitalization is now celebrating his future without sickle cell disease.

Samuel Idahosa spent his childhood in Nigeria in and out of hospitals, suffering debilitating pain that landed him in the hospital at least once a month. His parents never told him about his sickle cell diagnosis because of the social stigma surrounding the disease in their home country.

When his family moved to California in 2016, the then-15-year-old finally learned the truth during a routine blood test. He also discovered that his younger sister had died from the same disease and that finding better treatment for him was the main reason his family relocated.

Sickle cell disease affects more than 100,000 Americans and causes red blood cells to form crescent shapes that clump together and restrict blood flow. The result is chronic anemia and episodes of severe pain that Idahosa compared to migraines lasting several days.

Even simple activities like a mountain trip could trigger a crisis because lower oxygen levels at high altitudes put extra strain on his cardiovascular system. As a child in Nigeria, Idahosa was forbidden from playing sports or running with friends, though he sometimes rebelled and paid the price with hospitalizations that lasted one to two weeks.

Everything changed in 2025 when Idahosa received a novel gene therapy treatment at UCLA Health that modifies red blood cells so they no longer sickle. At 24, after enduring a lifetime of pain and restrictions, he's now considered cured.

Why This Inspires

Idahosa's cure represents hope for the millions worldwide living with sickle cell disease, particularly in sub-Saharan Africa where Nigeria and several neighboring countries account for 80% of global cases. The gene therapy he received offers a potential cure rather than just symptom management, transforming what was once a lifetime sentence of pain and limitations into a treatable condition.

His story also highlights how far medical innovation has come in just the past few years. The same disease that took his sister's life and forced his family to leave their home country is now being conquered through cutting-edge treatments available right here in the United States.

Recently honored at a UCLA men's volleyball practice at Pauley Pavilion, Idahosa now lives the active life he always dreamed of as a child watching from the sidelines.
