The Food and Drug Administration’s approval on Friday of two groundbreaking gene therapy treatments for sickle cell disease has brought a rare moment of hope and celebration to people with the agonizing blood disorder.The Food and Drug Administration’s approval on Friday of two groundbreaking gene therapy treatments for sickle cell disease has brought a rare moment of hope and celebration to people with the agonizing blood disorder.
But there is no clear path for the new therapies — one-time treatments so effective in clinical trials that they have been hailed as cures — to reach the countries where the vast majority of people with sickle cell live. Shortly after the approval their manufacturers announced sticker prices in the millions of dollars: $3.1 million for Lyfgenia, made by Bluebird Bio, and $2.2 million for Casgevy, made by Vertex Pharmaceuticals.But there is no clear path for the new therapies — one-time treatments so effective in clinical trials that they have been hailed as cures — to reach the countries where the vast majority of people with sickle cell live.

Lyfgenia will launch in the United States. Vertex has been prioritizing winning approval in six wealthy countries — the United States, Italy, Britain, France, Germany and Saudi Arabia — that, by one estimate, are home to 2 percent of the global sickle cell population.Lyfgenia will launch in the United States.

Three-quarters of the world’s sickle cell patients are in sub-Saharan Africa. Several million of them are believed to be sick enough that they would be eligible for the new therapies, compared with some 20,000 in the United States.Three-quarters of the world’s sickle cell patients are in sub-Saharan Africa.

Many African patients have been closely following news online of the treatments’ success in clinical trials. In Tanzania, information about Casgevy spread a few months ago through a WhatsApp group that Shani Mgaraganza set up for mothers of children with sickle cell. Her son, Ramadhani, 12, and daughter Nasra, 10, have the inherited disorder, which causes episodes of searing pain and damages their organs. She said the therapy sounded like a miracle.
“Everyone said, ‘Thanks God, our kids will be well,’” she said.
Then the mothers learned what it was likely to cost. “It would be billions of Tanzanian shillings,” Ms. Mgaraganza said. “No one can afford this. It was demoralizing.”
