A breakthrough in HIV Treatment: First Functional Cure in France
In a groundbreaking medical achievement,a woman in France has shown signs of a functional cure for HIV following an allogeneic bone marrow transplant. This remarkable case, the first of its kind in France, unfolded at the Human Immunodeficiency Details adn care Center (Cisih) in Sainte-Marguerite hospital, Marseille.
the patient, diagnosed with HIV in 1999, had been on antiretroviral therapy for years. By 2010, her viral load became “undetectable,” a critically important milestone in HIV management. However, as Dr. Sylvie Bregigeon explains, “an undetectable viral load is not synonymous with cure,” as traces of the virus can remain dormant in the body.
In 2020, the patient faced another health challenge: acute myeloid leukemia.this led too an allogeneic bone marrow transplant, a procedure that would inadvertently change the course of her HIV treatment. The donor carried the Delta32 genetic mutation in the CCR5 gene, a critical co-receptor that HIV uses to enter cells. This mutation effectively blocks the virus from infecting new cells.
After the transplant, the patient continued her antiretroviral treatment for three years. In October 2023, she stopped the medication, and subsequent tests revealed the total absence of the virus in her body. “The results remained negative, and his CD4 + T lymphocyte count increased significantly,” reported Dr. Bregigeon.
This case offers a glimmer of hope for the future of HIV treatment. While bone marrow transplants are not a feasible solution for all due to their complexity and risks, this success underscores the potential of genetic interventions in achieving a functional cure.
Key Highlights

In a remarkable medical breakthrough,a woman in France has achieved a functional cure for HIV following an allogeneic bone marrow transplant. This case, the first of its kind in France, marks a important milestone in HIV treatment and opens new avenues for research. To delve deeper into this groundbreaking development, we sat down with Dr. Amélie Laurent, a leading expert in infectious diseases and HIV research, to discuss the implications and future possibilities of this achievement.
Interview with Dr. Amélie Laurent: Understanding the Functional Cure for HIV
Senior Editor (Sarah Collins): Dr. Laurent, thank you for joining us today. This case has sparked immense interest in the medical community. Can you start by explaining what a functional cure means in the context of HIV?
Dr. Amélie Laurent: Absolutely, Sarah. A functional cure refers to a state where the virus is no longer detectable in the body, even after stopping antiretroviral therapy (ART). It doesn’t mean the virus is entirely eradicated, but it’s controlled to the point that it doesn’t replicate or cause harm. This is a significant step forward because, until now, ART has been the primary way to manage HIV, but it requires lifelong treatment.
Sarah Collins: This patient underwent an allogeneic bone marrow transplant for acute myeloid leukemia. How did this procedure lead to the functional cure?
Dr. Amélie Laurent: The key lies in the donor’s genetic profile. The donor carried the Delta32 mutation in the CCR5 gene, which is a co-receptor HIV uses to enter immune cells. This mutation naturally blocks the virus from infecting new cells. When the patient received the donor’s bone marrow, her immune system was essentially “rebooted” with cells resistant to HIV. Over time, this lead to the absence of detectable virus in her body, even after stopping ART.
Sarah Collins: Does this mean bone marrow transplants could be a viable solution for all people living with HIV?
Dr. Amélie laurent: Unfortunately, no. Bone marrow transplants are highly complex and risky procedures, typically reserved for life-threatening conditions like leukemia. Thay aren’t feasible for the broader HIV population. However, this case is incredibly valuable because it highlights the potential of targeting the CCR5 gene. It opens the door for exploring gene-editing technologies, like CRISPR, as a safer and more scalable approach.
Sarah Collins: what are the next steps in translating this case into broader HIV treatment strategies?
Dr. Amélie Laurent: The focus now is on developing gene therapies that can replicate the effects of the Delta32 mutation without the need for a bone marrow transplant.Early-stage clinical trials are already exploring CRISPR-based interventions to disable the CCR5 gene. Additionally, we’re studying how to enhance the immune system’s ability to control HIV more effectively. This case is a beacon of hope, but it’s just the beginning of a long journey.
sarah Collins: What does this breakthrough mean for people living with HIV today?
Dr. Amélie Laurent: it’s a powerful reminder that we’re making progress. While ART remains the cornerstone of HIV management, this case shows that a cure is within the realm of possibility. It also underscores the importance of continued research and investment in innovative treatments. For patients, it’s a message of hope—that one day, they may no longer need daily medication to manage thier condition.
Sarah Collins: Thank you, Dr. Laurent, for sharing your insights. This is undoubtedly a pivotal moment in the fight against HIV.
Dr. Amélie Laurent: Thank you, Sarah. It’s an exciting time,and I’m optimistic about the future of HIV treatment.
