LifeSouth Stem Cells Headed to Space – Free Press of Jacksonville – Jacksonville Free Press

JACKSONVILLE, Fla. April 26, 2023 LifeSouth Community Blood Centers, headquartered in Gainesville, Fla., was selected to provide CD-34 cells (stem cells) to Dr. Abba Zubair of Mayo Clinic in Florida for his research study aboard the International Space Station. This is a collaborative research study that includes BioServe Space Technologies, University of Colorado Boulder and ClinImmune, University of Colorado Anschutz Medical Campus, Denver and Mayo Clinic.

Dr. Zubair and others are studying how these stem cells will divide or expand in space versus how the same cells expand on Earth with the ultimate goal that these cells could be used for cancer treatment.

It is an honor for LifeSouth to be selected by Dr. Zubair to provide stem cells for this important research, said LifeSouth President and CEO, Kimberly Kinsell. By partnering with medical researchers like Dr. Zubair, with their incredibly important work, we are helping to advance lifesaving medical research. This aligns with LifeSouths core mission of saving lives.

A Northrup Grumman Cygnus spacecraft is scheduled to launch from Kennedy Space Center in May 2023 and will carry the cryogenically preserved cells provided by LifeSouth to the International Space Station. Crew members on board will thaw the cells and seed them into specialized hardware to allow them to expand.

Products being used for this study are produced by LifeSouth from umbilical cord blood collected by the LifeSouth Cord Blood Bank that are not eligible for transfusion. Mothers can donate their newborns umbilical cord blood for transplant at hospitals partnering with LifeSouth locally at UF Health and Baptist Medical Center South. The cord blood collected is banked and listed on the Be the Match Registry, making it available for patients needing a stem cell transplant. If the cord blood is not viable for transplant, it can be used for medical research aimed at curing cancers, diseases and genetic disorders.

Luis Hernandez, Director of Cellular Therapies for LifeSouth, emphasizes the importance of cord blood donation to help patients and research programs advancing modern medicine. Our hospital partners and the families that donate their umbilical cord to LifeSouths public cord blood bank provide lifesaving opportunities to patients now and those who will benefit from future scientific breakthroughs.

Driving the CAR: The Road Ahead for Cell Therapy – Genetic Engineering & Biotechnology News

Programming human cells to perform desired therapeutic functions is the basis for the growing field of cell therapy. One key example is chimeric antigen receptor (CAR) T cell immunotherapy, in which patient-derived T cells are genetically modified to express artificial antigen-targeting receptors to allow redirection to attack tumors. While cell therapies have shown clinical promise, the field has navigated challenges relating to safety, barriers to activity due to tumor heterogeneity, immune cell exhaustion, and the immune-suppressive tumor microenvironment. In addition, the complex manufacturing of CAR-Ts and other cell-based therapies translates to high costs and places constraints on scale and accessibility.

In this interview (conducted by senior editor Fay Lin), we asked Geulah Livshits, Senior Research Analyst at Chardan, to assess the advances and challenges facing the cell therapy field. Livshits discusses how the field has progressed with advances in tumor-immune interactions, cell engineering technologies, as well as improvements in cell manufacturing and the logistics of cell therapy administration in the clinic.

(This interview has been edited for length and clarity.)

How would you describe the current state of CAR-T therapies? What are the challenges?

Livshits: Its been more than five years since the first approval of CAR-Ts targeting CD19 for B-cell leukemia and lymphoma. The field has learned a lot since then, both with respect to science and what it takes to make cell therapies work in the commercial setting. While these initial agents were approved in patients who had progressed in standard of care therapies (third-line or later), weve also seen some CAR-Ts outperform standard-of-care chemotherapy in second-line lymphoma over the past year and gain approval in additional lymphoma subsets. This has allowed these advanced therapies to be used in earlier line settings, as well as in larger numbers of patients.

Beyond CD19, there has been a lot of success with CAR-Ts for multiple myeloma, targeting B-cell maturation antigen (BCMA), where some agents have shown response rates of up to 95% and thus far have impressive durability. This has led to interest in developing engineered cell therapies for solid tumors, which account for close to 90% of cancer deaths in the United States.

CAR-T manufacturing is complex as they are living drugs. It involves cell collection, genetic engineering within appropriate specifications such as viability, and then infusion back into the patient. Approved CAR-Ts are autologous, meaning that theyre manufactured individually for each patient. As a result, you cant scale up by making a bigger batch of cells. You have to scale out by making more batches at once and have the equipment to run those batches as patients need them. Theres a lot of logistics involved in ensuring that cancer patients who are eligible to receive CAR-Ts can actually get them manufactured and delivered in a timeframe during which they can still benefit.

CAR-Ts are also not the only modalities that are being developed for their indications. For example, bispecific antibodies (bsAbs) and to some extent, antibody-drug conjugates are also being developed for similar targets. Those are off-the-shelf biologics. Data on cell therapies are being analyzed in the context of durability of response, safety, and convenience relative to what is also emerging on some of these other agents.

In principle, cell therapies can be engineered to have additional functionalities beyond the currently approved CAR-Ts. Some areas of active innovation include a few overlapping buckets. These strategies include expanding the use of cell therapies to solid tumors, enhancing the safety elements of cell therapy so that they could be used in earlier lines and in community and outpatient treatment settings, and addressing some of those logistical challenges that are associated with current cell therapies. Different groups are focusing on the identification of optimal targets and additional cargos that could be incorporated to drive activity, such as different cell sources and cell types that have distinct activity, safety profiles, and manufacturability.

How are currently approved CAR-Ts developed and administered to patients?

The current approved CAR-Ts, such as Kymriah, Yescarta, Abecma, Carvykti, etc. are patient specific. The process involves harvesting immune cells from the patient by apheresis, genetically modifying them with the vector to get the construct, and then expanding them over several days. While doses vary by product, several of them are above 1 million cells per kilogram. The engineered cells are typically frozen down, shipped to the patients hospital, and infused into the patient. The turnaround time is often around three weeks, sometimes more.

Once the cells are infused, they rapidly expand and reach peak levels within two weeks of infusion and then decline. The long-term persistence and kinetics are often variable between products, patients, and indications, but CAR-Ts can persist at detectable levels for months to years due to the long lifespan of T cells.

To promote the expansion and activity of CAR-Ts, patients typically undergo lymphodepletion conditioning, typically with chemo drugs, such as fludarabine and cyclophosphamide. This transiently depletes a patients own lymphocytes and removes the sinks for cytokines to allow them to be available to support CAR-T expansion. Those expanded CAR-Ts then circulate around the body and kill cells with their respective targets, such as CD19, BCMA, and others. That includes both cancer cells as well as normal B cells.

How effective are these CAR-T therapies?

Responses tend to be pretty high for CD19 cancers and multiple myeloma. Many of these patients achieve a complete response or partial clearance within four weeks. In many cases, 40% of lymphoma patients and high numbers of multiple myeloma patients can remain responsive up to two years post-treatment. However, the durability numbers vary.

While thats encouraging, theres still room for improvement, particularly in the third-line setting. The activity has been quite encouraging in these cancer types but the answer is [to be determined] in other indications as we start to look beyond the lowest hanging fruits. Durability, toxicity, and safety are other relevant metrics that people use to evaluate these therapies.

Speaking of toxicity, are there any toxicities associated with these CAR-T therapies?

Years of clinical experience have shown some clear patterns on that front. CAR-Ts have been associated with certain toxicities including cytokine release syndrome, macrophage activation syndrome, immune effector cell-associated neurotoxicity syndrome (ICANS), as well as infections. The infections are often related to the lymphodepletion component because youre eliminating a persons immune cells, but other components arise from different elements of the CAR-T expansion.

Clinicians who have been administrating these therapies over the past several years have been increasingly adept at navigating the safety issues and treating cytokine release syndrome by using tocilizumab, an IL6 antibody. ICANS has been managed using corticosteroids. The field is seeing increasing assessment of CAR-T administration in outpatient settings. It is also important to keep in mind that all of this is learned from blood cancers. The situation could be different in solid tumors, where cell therapy strategies have also been in the clinic for quite a while.

What is the history behind cell therapy in oncology?

Years before CAR-Ts were [developed], there was work from Steve Rosenbergs group back in the 1980s and 1990s at the National Cancer Institute that showed immune cells could be harnessed to mediate rejection of a tumor. Much of that work focused on tumor infiltrating lymphocytes (TILs). TILs could be isolated from a patients tumor and then grown up in culture to doses of billions of cells and then infused back into that patient. That approach led to durable regressions of late-stage solid tumors. The idea behind TILs is that T cells that are found within a tumor might be likely to be enriched for T cells that are reactive to that tumor. Expanding and reinvigorating those cells outside the body can help them mount a more successful attack against that tumor.

Historically in those studies, TILs werent engineered and there was much less understanding about how that worked. Now we know that T cells, via their T-cell receptors (TCRs), can recognize tumor cells and kill them, particularly when theyre expressing proteins that are derived from mutations. That approach has been quite heavily studied, particularly in cancers that have a high number of mutations like melanoma. Companies that are operating in that space, such as Achilles Therapeutics, Instil Bio, Iovance Biotherapeutics, KSQ Therapeutics, and Lyell Immunopharma, are working on professionalizing elements of isolation of the TILs, their expansion, as well as looking at different strategies to boost their activity, either by reducing exhaustion or increasing cell killing capabilities.

How does research in engineered TCRs compare with CAR-T research?

The major difference between CARs and TCRs is that TCRs can recognize protein targets that have been processed into short fragments and then are presented on the cell surface in the context of the major histocompatibility complex (MHC). Both cell-surface and intracellular proteins are presented this way, meaning TCRs can target a wide range of potential targets. However, these MHC complexes vary from person to person. What that functionally means from a therapeutic development standpoint is that separate TCR products do need to be produced to target distinct alleles of the human leukocyte antigen (HLA) system.

The prevalence of different alleles varies across geographies. For example, in the United States, its estimated that around 40% of the Caucasian population has the most common HLA allele. There are other frequencies for less common variants. A series of products would need to cover additional segments of that population. This is distinct from CAR-Ts, where the CAR comprises an antibody-like domain that then recognizes unprocessed protein targets on the surface of tumor cells. Its not restricted by these HLA allele specificities, but they are limited to targeting proteins on the surface of the cell. They have a narrower potential antigen target pool, but a broader potential patient coverage by not being HLA restricted.

The antibody-like binders of CAR-T constructs are restricted to recognizing cell surface proteins. Are they able to distinguish between tumor and normal cells bearing their target? What are some solutions for off-target effects?

The currently approved CAR-Ts cant distinguish between cancer cells and normal cells. They kill cells that have enough of the target, and that can lead to on-target off-tumor toxicity. In the case of B-cell cancers, that translates to depletion of normal B cells along with the cancer cells. While thats not ideal, its an acceptable trade-off given the activity profile, considering that a patient can get by without B cells, especially with supportive treatment. In other tumor types, this can pose a bigger safety risk. For example, a patient died during an early study of CAR-Ts targeting HER2 days after administration, potentially because the T cells recognized low levels of their target in the lung tissue, which led to high inflammation in the lung.

Companies and academic groups are looking at safety switches or regulatable CARs or logic gates to try to reduce those off-tumor toxicities. Theyre focusing on targets that are highly expressed in cancers and have more limited expression in health tissues. This is also where the TCR T cells come into play. Theres a larger target space of intracellular proteins used to select targets that are overexpressed in cancer or neoantigen peptides that arise from mutated proteins. Targets that are overexpressed in cancer, such as NY-ESO-1, MAGE-A4, and PRAME, are being explored by companies like Adaptimmune, Immatics, and Tscan Therapeutics, while others such as Affini-T Therapeutics are targeting neoantigens.

While the TCR T space has lagged behind CAR-Ts, there are several biotech-driven programs that are now in the clinic. Adaptimmune expects to complete a rolling BLA submission for its MAGE-A4 TCR T program for synovial sarcoma in the middle of this year. A key technological area of focus among programs that are either pre-clinical or early development is screening T-cell receptors to have that optimal binding affinity to their target, but also screening to make sure that they dont cross-react with other proteins in healthy cells. There are also strategies to functionalize different types of T cells, for example, not just CD8 cells but also CD4 cells. There are some programs being advanced in conjunction with histological markers to allow their use in patients who express the target and would be more likely to benefit from the treatment.

What are the challenges posed by the tumor microenvironment on the effectiveness of these therapies? How are these challenges addressed?

The tumor microenvironment is definitely seen as a major barrier for cell therapy, particularly in solid tumors. There are several immune suppressive signals from different cell types that can promote T-cell exhaustion or other elements of T-cell dysfunction. Over the past decade, there have been many academic and industry studies teasing out how these tumor microenvironment mechanisms work and what characteristics are associated with functionality vs dysfunctionality (e.g. using CRISPR screens to functionally identify genes whose disruption can promote T-cell activity).

Other approaches identify additional components, such as cytokines or switch receptors, that can convert negative signals into positive or co-stimulatory signals to further boost activity in these immune suppressive microenvironments. These different approaches are expected to move through clinical trials in the coming years. Companies are also looking at combining T-cell therapies with approved checkpoint inhibitors as another way to boost activity.

How can off-the-shelf strategies simplify the manufacturing workflow of these therapies?

An advantage of off-the-shelf approaches is that the complex manufacturing and engineering does not have to be done individually for each patient. As a result, there is no 3-4 week lag to treatment. Also, in some cases, patients who have gone through multiple rounds of therapy may not have immune cells of sufficient quality or quantity to make a great autologous cell product.

The challenge is that immune systems are good at recognizing and eliminating foreign cells. Donor T-cells may attack a patients body (graft-versus-host disease, GvHD) or the bodys own immune cells can recognize donor cells as foreign and attack those. GvHD can be avoided by eliminating the endogenous TCR and T cells using tools such as gene editing, or by using other cell types that dont have this GvHD property. The issue with GvHD seems to be solvable with current technologies, but the immune invasion part is a bit more complicated. There are several strategies that are in development and the optimal approach remains to be seen at present. Companies such as Allogene Therapeutics, Beam Therapeutics, Caribou Biosciences, CRISPR Therapeutics, Precision BioSciences, and Sana Biotechnologies, are using different strategies to evade rejection from the patients T or NK cells.

There are several companies using NK cells, a cell type expected to have a shorter persistence. NK cells can be given at doses of over 1 billion cells in multiple administrations and potentially multiple cycles. One of the other attractive features of NK cells is that there seems to be a lower propensity towards cytokine release syndrome. That, in addition to engineering them with a CAR, can work in conjunction with some therapeutic antibodies to kill by multiple methods.

Different sources of NK cells are being explored by companies in the space. What is the impact of the starting material on the manufacturing process, costs, and attributes of the final product?

For NK cells, there have been a few different cell-sourcing strategies. Some groups, such as Nkarta, are developing donor-derived NK cells that are taken from other people and expanded. Others such as Fate Therapeutics, Century Therapeutics, and Shoreline Biosciences, are advancing NK cells that are derived from induced pluripotent stem cells (iPSCs). Companies like Takeda are advancing NK cells that are isolated from cord blood, which might have distinct properties. Donor-derived processes might yield expansion of NK cells several thousand-fold over a 2-3 week period and generate hundreds to thousands of doses per round. As this isnt bespoke, companies are able to scale up for commercial use. What that translates to in terms of cost per dose will depend on the dose paradigms that might end up being effective. Its still early days for the space, and the optimal dose regimens that would be used in commercial settings are not yet defined.

The difference with iPSC-derived therapies is that they can be expanded theoretically indefinitely and thus could be used to generate a clonally derived cell bank. This means that you can do all of the genetic engineering and have those associated costs upfront, freeze down a working cell bank, run a manufacturing batch, take cells from the bank and adjust culture conditions to differentiate them into NK cells. As its off-the-shelf, a batch can be hundreds or thousands of doses, depending again on manufacturing scale and dose levels and the exact process. Each of these approaches has its advantages and open questions.

What are the prospects for CRISPR, base and prime editing in the CAR-T field?

Various gene editing approaches are being used in cell therapy, particularly in the immune evasion setting. Were also starting to see use in autologous settings. For example, disruption of PD-1 in TILs from Iovance is an example of gene editing being used in cell-based therapies. There is interest in other approaches, such as base and prime editing that dont cause double-strand DNA breaks. Those approaches can make it easier to edit multiple genes at once while avoiding translocations. While current approved CAR-Ts use viral vectors to deliver the CAR construct, there is interest in using other approaches to insert the CAR or TCR construct, or other elements using non-viral approaches to target them in a particular location.

Desert Hot Springs man comes forward as fifth person in remission … – Desert Sun

'I still have to remind myself that it's real'

Video: Paul Edmonds is fifth person in HIV remission

Paul Edmonds, a current Desert Hot Springs resident, is the fifth person living with HIV worldwide to go into full remission following a stem cell transplant.

Taya Gray, Palm Springs Desert Sun

For the past two years, Paul Edmonds has been part of an extremely exclusive club with a membership that has reached five people.

After navigating HIV for more than 30 years, along with a leukemia diagnosis that came in 2018, a life-saving stem cell transplant became available thanks to a donor who had a rare genetic mutation that makes the body resistant to most strains of HIV. In 2021, Edmonds stopped taking his HIV medication, what he was dependent on for almost half his life. Today the 67-year-old who lives in Desert Hot Springs is the fifth person in the world in remission of HIV.

Edmonds joins four others who have received similar news, including the late Palm Springs residentTimothy Ray Brown (who was known as the "Berlin Patient"), the first person cured of the virus, who died from a reoccurrence of cancerin 2020. Others who are in remission of HIV are "London Patient" Adam Castillejo, "Dsseldorf Patient" Marc Franke and the "New York Patient," the first woman to be considered cured who has not come forth publicly. Edmonds is the eldest among the group and had HIV the longest.

"I can remember the day and hearing about Timothy Ray Brown, that was huge," Edmonds told The Desert Sun in a recent interview. "That was the first time that I ever thought there could be a cure."

After two years of being anonymously known as the "City of Hope Patient," he decided to publicly come forward with his story. By sharing his journey, he wants to advocate for and offer hope to those living and aging with HIV that a cure could be possible one day.

Edmonds grew up in a small town in Georgia about 100 miles northeast of Atlanta. During his high school years, he struggled with his sexual identity and didn't have a support system because he kept it all to himself. His "lifesaver" at the time was his involvement in his school's band, which consisted of a close-knit group of people, some of whom he's still in contact with today.

By the end of his senior year, Edmonds felt he couldn't handle the pressure anymore. He decided to live with his cousins in Pensacola, Florida, where he would finish high school and begin college, until he moved back to Atlanta. He received therapy, found support and was able to "accept who I was and come out" as a gay man.

With a different outlook on life, Edmonds, 21 at the time, made the decision to move to San Francisco in 1976.

"Gay men were kind of flocking there from all over at that time," he said of the California city. "It was just an unbelievable experience. I'd never seen anything like it, and I no longer felt alone. It was just exciting and thrilling."

Everything was "just great" until the 1980s rolled around, and many of his peers started getting sick. "No one knew what was going on," Edmonds said about that time, although many would refer to it as a "gay cancer."

Human immunodeficiency virus, more commonly referred to as HIV, is a virus that attacks cells that help the body fight infections. If left untreated, it can lead to AIDS, or acquired immunodeficiency syndrome. On June 5, 1981, the Centers for Disease Control and Prevention reported on the first five cases of what would be known as AIDS.

Rare lung infections and anaggressive cancer calledKaposis sarcoma first began to show among men who have sex with men (MSM) in 1981, and by the end of the year, there were 270 reportedcases of severe immune deficiencyamong MSM. The following year,more cases appeared among MSM in Southern California, which suggested the illness wassexual,leading to the name "gay-related immune deficiency." Cases also surfaced among those who inject drugs, hemophiliacs and Haitians.

Today, it is widely understood that the virus can be spread to all people, though some are still at higher risk of infection. Approximately84.2 million people around the world have been infected by HIV since the start of the epidemicand40.1 million people have died from AIDS-related illnesses.

By the mid-1980s, the first HIV blood test was developed, but Edmonds was not ready to get results himself.

"Anyone who I knew who was testing positive was dead within two years," he said. "I just wasn't ready to go there."

He moved to Los Angeles for a few years to change his environment, but moved back to San Francisco in 1988. That same year, his father died, which served as the catalyst for Edmonds getting tested. The result came back positive, and because his helper T cell count was below 200 then, he was diagnosed with AIDS. He was 33.

"It just felt like my heart sank," Edmonds recalled, though he noted he did not feel sick. "The intern who was my doctor in this clinic, I can see her emotions. I think it was a hard thing for her to do."

He began using AZT, the first drug to gain approval from the U.S. Food and Drug Administration for treating AIDS. The drug helped decrease deaths and infections among those who were diagnosed with the virus, although it had serious side effects, such as intestinal problems, nausea, vomiting and headaches. Around the time Edmonds began taking the drug, doctors decided to cut the dosage in half, which lessened those effects. As new drugs became available, he would switch to them, and he "pretty much felt sick all the time."

"But I did what I had to do," he added. "I am not a person who just easily gives up. I don't look to the worst-case scenario, I don't allow myself to."

Though things looked dark in the HIV/AIDS fight back then, Edmonds focused on living in the moment and taking his diagnosis one step at a time. As medical advancement came, like protease inhibitors, medications that help slow the progression of HIV, he would allow himself to think about the future and felt hopeful that things would be brighter.

Sure enough, the birthdays kept coming. He always dreamed of having a big party for his 50th birthday, and he got to enjoy that moment surrounded by 100 guests in a lodge on the Russian River.

Edmonds also said he had an "incredible" support system in his life. The LGBTQ community "stepped forward" and helped when no one else would. Then in February 1992, during happy hour at the San Francisco bar Midnight Sun, he met Arnie House, who had served in the Air Force.

"It really was kind of like love at first sight. I don't know that we knew that right then, but that's what it was," Edmonds said of his husband. "Once we met, we've had very few days apart."

Edmonds encouraged House to get tested for HIV, who also received a positive diagnosis. But that didn't change anything between them, as they've "always been there for each other," Edmonds said.

In August 2018, Edmonds was diagnosed with myelodysplastic syndrome, which eventually developed into acute myeloid leukemia, a cancerthat starts in the bone marrow but often moves into the blood. Those living and aging with HIV are at higher risk of developing leukemia and other blood cancers due to suppressed immune systems.

It was recommended that Edmonds start chemotherapy as soon as possible, and later undergo a stem cell transplant. At the same time, Edmonds and House were planning on moving to the Palm Springs area, and he was referred to seek treatment at City of Hope in Duarte, one of the highest-volume transplant centers in the nation.

Not only would doctors look for a donor to address his leukemia, but also one who carried a rare mutation, homozygous CCR5 delta 32 mutation, which makes people resistant to most strains of HIV infection. Only roughly 1% of people carry this mutation. The four other people who have been declared in remission of HIV have received transplants that have targeted their HIV and a type of cancer.

It took almost a month before a donor was found via the Be The Match donor registry. Before he could undergo the transplant, his acute myeloid leukemia had to go into remission. He went through three rounds of chemotherapy, and he developed a fungal infection in his lungs during one. He also had to change the antiretroviral drugs he was taking in order to minimize drug interactions with the chemotherapy.

Finally in mid-January 2019, his leukemia went into full remission thanks to a reduced intensity chemotherapy that was developed for older patients. Afterward, he received a week of chemotherapy to wipe out his immune system and prepare his body to receive his donor's healthy stem cells, which he said was the "hardest of all of them."

But despite all the pain and side effects, "I didn't have to think at all whether I wanted to move forward to get a bone marrow transplant," Edmonds said. "I didn't even see it as an option ... it was that or death."

On Feb. 6, 2019, the transplant lasted about 30 to 40 minutes via an IV transfusion. Edmonds said he didn't have any side effects and almost immediately "felt great." Nurses even gave him a medal and started singing "Happy Birthday" to celebrate the moment.

"New life came into me," he said, noting that his blood type changed to his donor's, which is common in transplants. Some recipients might also notice other changes regarding allergies or their hair texture. "I was kind of hoping I would start getting some new hair, but that didn't happen. That's OK," he joked. Among lingering side effects that Edmonds deals with are dry eyes and mouth sores.

Edmonds had to stay close to the hospital after his treatment, and many friends from across the country stayed with him and made sure he was never alone. "I just had the best time," he recalled of all the trips they took, like playing tourist in his once-home of Los Angeles.

Doctors carefully monitored Edmonds following his transplant for both his cancer and HIV status.

Dr. Jana Dickter, associate clinical professor with City of Hopes Division of Infectious Diseases, did a number of tests to see if there was any evidence of HIV found in his body. When she and her colleagues could not find any, she opened up a "second trial" and asked Edmonds to stop taking his HIV medications.

"I monitored him for any occurrence of HIV virus and this entailed getting blood tests on him every week initially and then converted to every two weeks just because we wanted to catch if there was any recurrence in the system and start him back on his medications," Dickter said. "The longer the time went, there was no evidence of circulating HIV."

Additional testing was done in labs, such as challenging his cells with HIV, but they could not be infected with the virus, and there was no evidence of an HIV reservoir found in his body.

Edmonds officially stopped taking his HIV medication in March 2021.

"I still have to remind myself that it's real," he said of his in-remission HIV status. "But I'm feeling it."

There's still a little bit of worry in the back of his mind about whether his cancer or HIV will return, but he said he's gotten to the point where "it's OK for me to let myself believe it, and I absolutely believe it." He also said the people he's told locally have been "just thrilled for me and very, very supportive."

For Dickter, witnessing the journey firsthand has been "incredibly exciting." When she entered medical school in the 1990s, she got to see the excitement when antiretroviral therapy became available and it provided patients who were so close to death with a "second life." Fast forward to today, she was one of those in the room to tell a patient they were in remission of HIV.

"I've always wanted to be able to tell a patient that there was no evidence of remaining virus in their system, and at City of Hope we were able to do just this," Dickter said. "The experiences that he encountered, especially early on and the stigma and the fear, he's a true survivor of the epidemic, and it's so wonderful to see this happy ending for him and his family."

The success of Edmonds' treatment and his unique circumstances also give Dickter hope that it could be reciprocated in others. He was unique in the sense that, compared to the four other people who underwent transplants, he was the oldest patient, had been living with HIV the longest and had received reduced intensity chemotherapy. "This case gives me hope that there might be other opportunities in the future for older people who have HIV and blood cancers that we may be able to put them in remission for both," she said.

There's also plenty of research taking place at City of Hope in hopes of potentially finding a cure for HIV. Not only are there discussions about providing transplants for other patients with HIV and blood malignancies, but Dickter said there's an upcoming clinical trial that will look at chimeric antigen receptor T cells to treat HIV. She explained there has been preclinical research that has shown these "T cells can target and kill HIV-infected cells and potentially control HIV, and this has the potential to provide HIV patients with lifelong viral suppression without antiretroviral therapy."

Edmonds also hopes to be an advocate for HIV cure research and provide support wherever he can. He currently sits on the Community Advisory Board for RID-HIV (Reversing Immune Dysfunction for HIV-1 Eradication) Collaboratory, one of 10 Martin Delaney Collaboratories for HIV Cure Research funded by the National Institutes of Health, which he is "very honored" to be a part of. He is also in contact with his peers Castillejo, who has spoken at a number of conferences, and Franke, just beginning his public journey, and hopes to do work with them.

For now, Edmonds gets to live his life on his own terms, although he still visits City of Hope for routine care and tests. He and House are avid painters and have their art showcased throughout their home Edmonds paints more abstract pieces while House does more figurative work. Edmonds wants to create collages that tell his story in some way, but they also have a bit of work to do around their Desert Hot Springs home, where they've lived for almost two years. As they emerge out of mostly sheltering-in-place during the height of the COVID-19 pandemic, there are also plans to visit San Francisco this summer.

Aside from encouraging the HIV-positive community, there's also a part of Edmonds that hopes the intern who informed him of his AIDS diagnosis in 1988 stumbles upon his story and sees where life has taken him. Where he stands today is a moment so many have hoped for, and one that seemed unthinkable decades ago.

"It truly is a miraculous story," he said with a smile.

What is already known about this topic?

Waning of monovalent mRNA COVID-19 vaccine effectiveness against COVID-19associated hospitalization among adults is recognized; however, little is known about the durability of protection provided by these vaccines against COVID-19associated invasive mechanical ventilation (IMV) and in-hospital death during the Omicron variant period.

What is added by this report?

Monovalent mRNA vaccination was 76% effective in preventing COVID-19associated IMV and death <6 months after the last dose and remained 56% effective at 12 years.

What are the implications for public health practice?

Monovalent mRNA COVID-19 vaccines provided substantial, durable protection against COVID-19associated IMV and death. All adults should remain up to date with recommended COVID-19 vaccination to prevent critical outcomes of COVID-19.

As of April 2023, the COVID-19 pandemic has resulted in 1.1 million deaths in the United States, with approximately 75% of deaths occurring among adults aged 65 years (1). Data on the durability of protection provided by monovalent mRNA COVID-19 vaccination against critical outcomes of COVID-19 are limited beyond the Omicron BA.1 lineage period (December 26, 2021March 26, 2022). In this case-control analysis, the effectiveness of 24 monovalent mRNA COVID-19 vaccine doses was evaluated against COVID-19associated invasive mechanical ventilation (IMV) and in-hospital death among immunocompetent adults aged 18 years during February 1, 2022January 31, 2023. Vaccine effectiveness (VE) against IMV and in-hospital death was 62% among adults aged 18 years and 69% among those aged 65 years. When stratified by time since last dose, VE was 76% at 7179 days, 54% at 180364 days, and 56% at 365 days. Monovalent mRNA COVID-19 vaccination provided substantial, durable protection against IMV and in-hospital death among adults during the Omicron variant period. All adults should remain up to date with recommended COVID-19 vaccination to prevent critical COVID-19associated outcomes.

Monovalent mRNA COVID-19 vaccination has been shown to prevent hospitalization and critical outcomes, including IMV and death, during SARS-CoV-2 Alpha, Delta, and early Omicron variant periods (2,3). However, rapid waning of COVID-19 VE against infection, outpatient illness, and hospitalization has been observed during Omicron variant predominance (4). Understanding the durability of protection provided by monovalent mRNA vaccination against critical outcomes is vital. Although a bivalent mRNA dose was recommended on September 1, 2022, for all persons who had completed a primary COVID-19 vaccination series, bivalent vaccination coverage among adults aged 18 years is 20%, and most adults have only received monovalent mRNA vaccines (1,5). In addition, COVID-19 VE against hospitalization might be artificially reduced by routine testing for SARS-CoV-2 at admission, which can detect SARS-CoV-2 infection in patients admitted for reasons other than COVID-19 (4,6,7). VE against critical outcomes might be less susceptible to this bias and is therefore needed to help guide COVID-19 vaccination policy regarding revaccination intervals.

Data from the Investigating Respiratory Viruses in the Acutely Ill (IVY) Network were used to conduct a case-control analysis measuring the effectiveness of monovalent mRNA COVID-19 vaccination against COVID-19associated IMV and in-hospital death. During February 1, 2022January 31, 2023, adults aged 18 years admitted to 24 hospitals in 19 U.S. states who met a COVID-19like illness case definition and received SARS-CoV-2 testing were enrolled. IVY Network methods have been described previously (2,3). Briefly, case-patients were defined as those who received a positive SARS-CoV-2 reverse transcriptionpolymerase chain reaction (RT-PCR) or antigen test result within 10 days of illness onset and within 3 days of hospital admission, and either received IMV or died in the hospital within 28 days of admission. Control patients were defined as those who received negative SARS-CoV-2 and influenza test results by RT-PCR within 10 days of illness onset and within 3 days of hospital admission. Patients who received positive influenza test results were excluded from the analysis because of potential correlation between COVID-19 and influenza vaccination behaviors (8).

Demographic and clinical data, including receipt of IMV and in-hospital death within 28 days of admission, were collected through electronic medical record (EMR) review and patient or proxy interview. COVID-19 vaccination history was ascertained from state or jurisdictional registries, EMRs, vaccination cards, and self-report. Patients were included in the analysis if they 1) received zero COVID-19 vaccines doses (unvaccinated) or 2) received 2, 3, or 4 monovalent mRNA COVID-19 vaccine doses (monovalent-vaccinated), with the last dose received 14 days before illness onset for a primary series dose or 7 days before illness onset for a booster dose. Patients were excluded from the analysis if they were immunocompromised,** received a non-mRNA COVID-19 vaccine dose, received only 1 monovalent mRNA COVID-19 vaccine dose, received a bivalent mRNA COVID-19 vaccine dose, or for other reasons that made the patient ineligible.

VE against IMV and in-hospital death was calculated using logistic regression, in which the odds of monovalent mRNA vaccination (versus being unvaccinated) were compared between COVID-19 case-patients and control patients. Logistic regression models were adjusted for U.S. Department of Health and Human Services region, calendar time in biweekly intervals, age, sex, and self-reported race and Hispanic ethnicity. VE was calculated as (1 adjusted odds ratio) x 100%. Results were stratified by age group, time since receipt of last monovalent mRNA vaccine dose, and number of monovalent mRNA vaccine doses received. Differences between VE point estimates with nonoverlapping 95% CIs were considered statistically significant. Analyses were conducted using SAS (version 9.4; SAS Institute). This activity was determined to be public health surveillance by each participating site and CDC and was conducted in a manner consistent with all applicable federal laws and CDC policy.

During February 1, 2022January 31, 2023, a total of 6,354 immunocompetent control patients and COVID-19 case-patients with IMV or in-hospital death were enrolled in the IVY Network. After exclusion of 1,933 patients,*** 4,421 (70%) were included in the analysis (362 case-patients and 4,059 control patients). Patients were most commonly excluded because of receipt of a bivalent mRNA COVID-19 vaccine dose (446 [23% of excluded patients]), receipt of a non-mRNA COVID-19 vaccine (392 [20%]), or receipt of only 1 monovalent mRNA COVID-19 vaccine dose (260 [13%]). Among included patients, the median age was 64 years (IQR=5375 years) (Table 1). Ninety-one percent of patients had one or more chronic condition, and 20% had a previous self-reported or documented SARS-CoV-2 infection. Among 362 case-patients with IMV or in-hospital death, 146 (40%) were unvaccinated, 216 (60%) were monovalent-vaccinated, 293 (81%) received IMV, and 156 (43%) died in the hospital within 28 days of admission. Among 4,059 control patients, 979 (24%) were unvaccinated, and 3,080 (76%) were monovalent-vaccinated.

Among monovalent-vaccinated patients, the median interval from receipt of last dose to illness onset was 248 days (IQR=138378 days) (Table 2). When compared with unvaccinated patients, the VE of 24 monovalent mRNA vaccine doses against IMV and in-hospital death was 62%. VE was 57% among patients aged 1864 years and 69% among patients aged 65 years. When stratified by interval since receipt of last monovalent dose, VE against IMV and in-hospital death was 76% at 7179 days, 54% at 180364 days, and 56% at 365 days. Within each interval since receipt of last monovalent dose, VE estimates did not differ significantly by number of doses received. VE point estimates were higher 7179 days since last dose compared with 180 days since last dose, although 95% CIs overlapped.

Among immunocompetent adults aged 18 years admitted to 24 hospitals in the IVY Network in 19 U.S. states, receipt of 24 monovalent mRNA COVID-19 vaccine doses provided substantial protection against COVID-19associated IMV and in-hospital death during the Omicron variant period. Protection was highest during the first 6 months after the last monovalent dose, with persistent residual protection remaining after 6 months and sustained at 12 years. Monovalent mRNA vaccination also provided substantial protection against COVID-19associated IMV and death among adults aged 65 years, the age group that remains at highest risk of severe COVID-19 (1). These findings underscore the importance of staying up to date with COVID-19 vaccination to prevent critical outcomes of COVID-19, including optional, additional bivalent mRNA booster doses for persons at highest risk of severe disease.

A previous analysis from the IVY Network showed high effectiveness of monovalent mRNA COVID-19 vaccination against COVID-19associated IMV and death during the Delta and early Omicron variant periods (2). The current analysis expands on these findings by reporting monovalent mRNA COVID-19 VE against IMV and in-hospital death for a full year during the Omicron variant period. These results suggest some waning of protection against IMV and death after 6 months from receipt of the last dose but demonstrate clinically meaningful levels of protection for 1 year (median=455 days). In stratified analyses, VE appeared to correlate more closely with time since last dose than with total number of doses received. These findings are consistent with evidence from the United Kingdom showing that among adults aged 65 years, VE of monovalent COVID-19 vaccination against COVID-19associated mortality during the Omicron variant period was 49.7% for 2 doses and 56.9% for 3 doses after 40 weeks (280 days) from vaccination (9). Together, these results suggest maximal benefit of COVID-19 vaccination during the first 6 months after receipt, which should be considered along with trends in COVID-19 incidence and risk factors for severe disease when planning COVID-19 revaccination schedules.

The findings in this report are subject to at least four limitations. First, the sample size was insufficient to generate VE estimates for each Omicron lineage period separately or to calculate some VE estimates stratified by both time since last monovalent mRNA dose and number of doses received. Second, although case-patients had evidence of acute respiratory illness and received a positive SARS-CoV-2 test result, inclusion of case-patients who died or required IMV for reasons other than COVID-19 could have reduced VE because of misclassification. Third, previous SARS-CoV-2 infection was infrequently reported or documented among patients in this analysis, which prevented evaluation of the impact of previous infection on VE against critical outcomes. Finally, although VE estimates were adjusted for patient-level demographic characteristics, calendar time, and geographic region, residual confounding, including from COVID-19 antiviral treatment, cannot be excluded.

Since the start of the COVID-19 pandemic, approximately 1.1 million COVID-19associated deaths have occurred in the United States, with the majority occurring among patients aged 65 years. Monovalent mRNA COVID-19 vaccination provided substantial, durable protection against COVID-19associated IMV and death during the Omicron variant period, including among older adults. Protection against these critical outcomes appeared to correlate more closely with time since last dose than with total number of doses received. On April 18, 2023, bivalent mRNA vaccines became the only mRNA COVID-19 vaccines authorized for use in the United States. Only 42% of adults aged 65 years have received a bivalent mRNA COVID-19 vaccine dose and are up to date with COVID-19 vaccination (1). CDC recommends that all adults remain up to date with COVID-19 vaccination, including the updated bivalent vaccine, to prevent critical outcomes of COVID-19.
