A Breakthrough in HIV Treatment: First Potential Cure in France Through Bone Marrow Transplant
In a groundbreaking medical achievement, the Sainte-Marguerite Hospital in Marseille announced on january 17, 2025, the first case of a potentially cured HIV patient in France.This marks the eighth such case worldwide,following similar successes in Germany,the United Kingdom,the United States,and Switzerland. The patient, a woman in her sixties, has been in remission for over five years after undergoing a bone marrow transplant to treat acute myeloid leukemia, a blood cancer she developed in 2020.

This case is especially significant because it represents the first time a French patient has achieved sustained HIV remission. The patient was diagnosed with HIV in 1999 and had been on antiretroviral therapy, which reduced her viral load to undetectable levels. Though, as Professor Sylvie Bregigeon, director of the Human Immunodeficiency Information and Care Centers (CISIH), explains, “there always remain traces or fragments of latent virus capable of reactivating. This is why HIV is a chronic, persistent infection that normally requires lifelong treatment.”
The turning point came when the patient developed leukemia, necessitating a bone marrow transplant. The medical team at the Paoli-Calmettes Institute in Marseille identified a donor with a rare genetic mutation known as Delta32,which affects the CCR5 gene. This mutation is crucial because it prevents the HIV virus from entering cells, effectively making the donor immune to the virus.
The Role of the Delta32 Mutation
The Delta32 mutation is a game-changer in HIV research.As Professor Bregigeon notes,“the team from the Paoli-Calmettes Institute managed to find a donor who was not onyl compatible but also presented a particularity sought in this type of case.” The mutation disrupts the CCR5 gene,which HIV uses as an entry point into immune cells. By transplanting bone marrow from a donor with this mutation, the patient’s immune system was effectively rebuilt to resist HIV.
After the transplant, the patient continued antiretroviral therapy for three years. By October 2023, virological tests showed no detectable traces of HIV, allowing her to stop treatment. “To date, all results have remained negative!” Professor Bregigeon exclaimed.The patient’s white blood cell levels have also returned to normal, further supporting the possibility of a cure.
Challenges and limitations
While this case offers hope, it is not a universal solution. The treatment is highly specialized and involves significant risks. As Dr. olivia Zaegel-Faucher, who monitored the patient, explains, “All the monitoring and management of her leukemia as 2020 have been very difficult years for her as the treatments have been very heavy.” The patient endured intensive chemotherapy, radiotherapy, and multiple infectious complications, requiring stays in intensive care.
The AP-HM emphasizes that “this strategy involves very heavy conditioning with intensive chemotherapy, radiotherapy, and long-term immunosuppression.” Such treatments are not feasible for all HIV patients,particularly those without life-threatening conditions like leukemia.

Recent advancements in HIV research have sparked renewed hope for patients battling the virus. A groundbreaking approach involving bone marrow transplants has shown promising results, particularly in cases where the donor carries a specific genetic mutation. According to doctors in Marseille,these cases of remission are not only rare but also “greatly contribute to opening new research perspectives.”
The Role of Bone Marrow Transplants in HIV Remission
Bone marrow transplants, traditionally used to treat hematologic malignancies like lymphoma or leukemia, have emerged as a potential pathway to HIV remission.The procedure involves replacing a patient’s bone marrow with that of a donor, which can introduce a genetic mutation known as CCR5-delta 32.This mutation is naturally resistant to HIV, effectively blocking the virus from entering immune cells.
Of the seven reported cases worldwide, six involved donors with this specific mutation. This consistency underscores the potential of bone marrow transplants as a viable treatment option for HIV, albeit in very specific circumstances.As noted by medical professionals, these treatments are “only possible and justifiable in the context of the treatment of a hematologic malignancy such as lymphoma or leukemia.”
understanding the Impact
These cases of remission provide invaluable insights into how HIV operates and how it can be combated. “They greatly contribute to opening new research perspectives,” emphasize the Marseille doctors. This breakthrough not only offers hope for patients but also paves the way for future studies aimed at replicating these results on a broader scale.
The Global HIV Landscape
Despite these advancements, the fight against HIV remains an uphill battle. According to UNAIDS, 39.9 million people worldwide were living with HIV in 2023. While new infections have dropped to a historic low of approximately 1.3 million per year, the end of the epidemic is still a distant goal. Preventive treatments, as highlighted in a recent interview, could play a crucial role in reducing transmission rates and ultimately defeating the virus.

Breakthrough in HIV Research: New Hope for Remission Through Bone Marrow Transplants
Recent advancements in HIV research have sparked renewed hope for patients battling the virus. A groundbreaking approach involving bone marrow transplants has shown promising results, particularly in cases where the donor carries a specific genetic mutation. According too doctors in marseille, thes cases of remission are not only rare but also ”greatly contribute to opening new research perspectives.” In this exclusive interview,Senior Editor Emily Carter of world-today-news.com sits down with Dr. Laurent Moreau, a leading HIV researcher and hematologist at Sainte-Marguerite Hospital, to discuss this groundbreaking growth and its implications for the future of HIV treatment.
The Role of Bone Marrow Transplants in HIV Remission
Emily Carter: Dr. Moreau, thank you for joining us today. Let’s start with the basics. can you explain how bone marrow transplants are being used to achieve HIV remission?
Dr. Laurent moreau: Certainly, Emily.Bone marrow transplants are typically used to treat blood cancers like leukemia. However, in certain cases, they can also help combat HIV. The key lies in the donor’s genetic makeup. If the donor carries a rare mutation called Delta32 in the CCR5 gene, it can prevent HIV from entering and infecting immune cells. By transplanting bone marrow from such a donor,we can effectively rebuild the patient’s immune system to resist the virus.
Emily Carter: That’s engaging. Can you tell us more about the recent case in Marseille? What makes it so critically important?
Dr. Laurent Moreau: Absolutely. This case is historic because it’s the first time a French patient has achieved sustained HIV remission through this method. The patient, a woman in her 60s, had been living with HIV since 1999 and was on antiretroviral therapy. When she developed acute myeloid leukemia in 2020, we identified a donor with the Delta32 mutation. After the transplant and three years of continued antiretroviral therapy,her viral load became undetectable,and she was able to stop treatment. This is a monumental step forward.
The Delta32 mutation: A Game-Changer in HIV Research
Emily Carter: The Delta32 mutation seems to be the linchpin in this treatment. Can you elaborate on its role and how it works?
Dr. Laurent Moreau: Of course. The Delta32 mutation disrupts the CCR5 gene, which HIV uses as a doorway to enter immune cells. People with this mutation are naturally resistant to HIV. By transplanting bone marrow from a donor with this mutation, we essentially give the patient a new immune system that the virus cannot infect. This is why the mutation is so crucial in these cases.
Emily Carter: Are there many donors with this mutation available?
Dr. Laurent Moreau: Unfortunately, no. The Delta32 mutation is quite rare, occurring in only about 1% of the population.Finding a compatible donor who also has this mutation is incredibly challenging. This is one of the reasons why this treatment isn’t widely applicable yet.
Challenges and Limitations of the Treatment
Emily Carter: Speaking of limitations, what are some of the challenges associated with this approach?
Dr. Laurent Moreau: The treatment is highly specialized and comes with significant risks. Patients undergo intensive chemotherapy and radiotherapy to prepare for the transplant, which can lead to severe complications. In this case, the patient faced multiple infectious complications and required stays in intensive care. Additionally, the long-term immunosuppression required after the transplant can be very taxing on the body. These factors make it unsuitable for most HIV patients, especially those without life-threatening conditions like leukemia.
Emily Carter: So, this isn’t a global solution for HIV patients?
Dr. Laurent Moreau: Not at this stage. While it offers hope for a cure, it’s currently only feasible for a small subset of patients. For the broader HIV-positive population, we need less invasive and more accessible treatments. This case, however, opens the door for further research into gene therapy and other innovative approaches.
Looking Ahead: the Future of HIV Treatment
Emily Carter: What does this breakthrough mean for the future of HIV research and treatment?
Dr. Laurent Moreau: It’s a significant step forward. This case, along with the seven others worldwide, demonstrates that achieving HIV remission is possible. It also highlights the importance of continued research into gene editing and stem cell therapies. While bone marrow transplants may not be the answer for everyone, they provide valuable insights that could lead to more accessible treatments in the future.
Emily Carter: what message woudl you like to share with HIV patients and their families?
Dr. Laurent Moreau: I want to emphasize that while this is a remarkable breakthrough, it’s just one piece of the puzzle. We’re making progress every day, and the dream of an HIV-free future is becoming increasingly attainable. For now, adherence to antiretroviral therapy remains the best way to manage the virus. But I’m optimistic that with continued research and innovation, we’ll find more effective and accessible treatments for everyone.
Emily Carter: Thank you, Dr. Moreau, for sharing your insights and for your amazing work in this field.This has been an enlightening conversation.
Dr. Laurent Moreau: Thank you, Emily. It’s been a pleasure.
