Some patients with blood cancers for whom all other therapeutic options have been exhausted have one final chance of getting rid of their disease: treatment with chimeric antigen-receptor (CAR) T cells.

Described as a “living drug,” the treatment involves genetically engineering the patient’s own blood cells and reinfusing them back into their system. These CAR T cells then hunt down and destroy cancer cells; in some cases, they manage to eradicate the disease completely.

About half of patients with leukemia or lymphoma and about a third of those with multiple myeloma who receive this treatment have a complete remission and achieve a functional “cure.”

But not all patients who could benefit from this therapy are able to get it. Some are spending months on waiting lists, often deteriorating while they wait. These patients have exhausted all other therapeutic options, and many are facing hospice and death.

The scope of this problem was illustrated by a recent survey of the centers that are certified to deliver this complex therapy.

The survey was led by Yi Lin, MD, PhD, associate professor of medicine at the Mayo Clinic, Rochester, Minn., and medical director for the cellular therapy program. It was published as an abstract at the annual meeting of the American Society of Clinical Oncology recently, although it was not presented there.

“We wanted to find out just how widespread this problem is,” Dr. Lin said, adding: “There had been nothing in the literature thus far about it.”

The team contacted 20 centers across the United States and received responses from 17. Results showed that the median time on the waiting list was 6 months and that only 25% of patients eventually received CAR T-cell therapy. An additional 25% were able to enter a CAR T clinical trial. The remaining 50% of patients either were enrolled in a different type of trial, entered hospice, or died.

For patient selection, all centers reported using a committee of experienced physicians to ensure consistency. They employed different ethical principles for selection. Some centers sought to maximize the total benefit, such as selecting the patients most likely to achieve leukapheresis or a clinical response, while others based their decisions on the time patients spent on waiting list or gave priority to the patients who were the “worst off” with the most limited therapeutic options.
 

Shortage affecting mostly myeloma patients

The shortages in CAR T-cell therapies primarily involve the products used for patients with multiple myeloma.

The problem has not, as yet, noticeably spilled over to lymphoma and leukemia treatments, which use a slightly different type of CAR T-cell therapy (it targets CD19, whereas the cell therapies used for myeloma target BCMA).

“We have backlog of myeloma patients who don’t have access,” said Nina Shah, MD, a hematologist and professor of medicine at the University of California, San Francisco. “We have only four slots for the two myeloma products but about 50-60 eligible patients.”

Long waiting times for CAR T cells for myeloma have been an issue ever since the first of these products appeared on the market: idecabtagene vicleucel (ide-cel; Abecma), developed by Bluebird Bio and Bristol-Myers Squibb. “As soon as it became available in March 2021, we had people waiting and limits on our access to it,” Dr. Shah said.

A second CAR T-cell therapy for myeloma, ciltacabtagene autoleucel (cilta-cel, Carvykti), developed by Janssen and Legend Biotech, received approval in February 2022. While that helped provide centers with a few more slots, it wasn’t sufficient to cut waiting times, and the demand for these myeloma therapies continues to outstrip the capacity to produce CAR-T products in a timely manner.

“For myeloma, the demand is very high, as most patients are not cured from any other existing myeloma therapies, and most patients will make it to fifth-line therapy where the two CAR T-cell products are approved right now,” said Krina K. Patel, MD, medical director of the department of lymphoma/myeloma in the division of cancer medicine at the University of Texas MD Anderson Cancer Center, Houston.

“We likely have 10 eligible CAR-T myeloma patients each month at our center,” she said, “but were getting two slots per month for the past 8 months, and now are getting four slots a month.”

“Our clinic has also experienced the impact of the low number of manufacturing slots offered to each cancer center for some CAR T-cell products,” said David Maloney, MD, PhD, medical director, Cellular Immunotherapy and Bezos Family Immunotherapy Clinic, Seattle Cancer Care Alliance.

He noted that, as with other cancer centers, for multiple myeloma they are provided a specific number of manufacturing slots for each treatment. “Our providers discuss which patients are most appropriate for available slots for that month,” said Dr. Maloney.

“Additionally, juggling patient schedules may be required to address the extended manufacturing time for some products. In some cases, clinical trials may be available in a more timely fashion for appropriate patients, and in some cases, switching to an alternative product is possible,” he commented.
 

Complex causes behind bottleneck

The cause of the current bottleneck for myeloma patients is complex. It stems from a shortage of raw materials and supply chain restraints, among other things.

While the biggest impact of shortages has been on patients with multiple myeloma, Dr. Patel pointed out that these constraints are also affecting patients with lymphoma at her institution, but to a lesser degree.

“This is multifactorial as to why, but most of the issues arise from manufacturing,” Dr. Patel said in an interview. “Initially, the FDA limited how many slots each new product could have per month, then there was a viral vector shortage, and then the quality-control process the FDA requires takes longer than the manufacturing of the cells actually do.”

On top of that, “we have about a 5% manufacturing fail rate so far,” she added. Such failures occur when the cells taken from a patient cannot be converted into CAR T cells for therapy.

Matthew J. Frigault, MD, from the Center for Cellular Therapies, Mass General Cancer Center, Boston, explained that the growing excitement about the potential for cellular therapy and recent approvals for these products for use in earlier lines of treatment have increased demand for them.

There are also problems regarding supply. Manufacture and delivery of CAR T is complicated and takes time to scale up, Dr. Frigault pointed out. “Therefore, we are seeing limited access, more so for the BCMA-directed therapies [which are used for myeloma].”

The shortages and delays likely involve two main factors. “For the newer indications, there is a significant backlog of patients who have been waiting for these therapies and have not been able to access them in the clinical trial setting, and manufacturing is extremely complicated and not easily scaled up,” he said.

“That being said, manufacturers are trying to increase the number of available manufacturing slots and decrease the time needed to manufacture cells,” Dr. Frigault commented.

Delays in access to myeloma CAR T-cell therapy are also affecting patient care at Fox Chase Cancer Center in Philadelphia. “We have had about one slot every 2 months for Abecma,” noted Henry Fung, MD, chair of the department of bone marrow transplant and cellular therapies at Fox Chase. “For Carvykti, there are only 32 certified centers in [the] U.S., and access is very limited.”

Dr. Fung explained that they have had to offer alternative treatments to many of their patients. “There are rumors that there’s shortage in obtaining raw materials, such as the virus used for transduction, although we have not encountered any problems in other CAR T products used for lymphomas.”
 

Pharma companies trying to meet the demand

This news organization reached out to the manufacturers of CAR T products. All have reported that they are doing what they feasibly can to ramp up production.

“The complexity of delivering CAR T-cell therapies is unlike any other traditional biologic or small-molecule medicine, using a patient’s own cells to start a highly sophisticated and personalized manufacturing process,” commented a spokesperson for BMS, which has two CAR T-cell products currently on the market.

“In this nascent field of cell therapy, we continue to evolve every day, addressing supply and manufacturing challenges head on by applying key learnings across our three state-of-the-art cell therapy facilities and two new facilities in progress.

“We have been encouraged by a steady increase in our manufacturing capacity, and we continue efforts to ramp up further to meet the demand for our cell therapies,” the BMS spokesperson commented. “We have already seen improvements in the stabilization of vector supply and expect additional improvements in capacity in the second half of 2022.”

Novartis said much the same thing. They have a “comprehensive, integrated global CAR-T manufacturing footprint that strengthens the flexibility, resilience, and sustainability of the Novartis manufacturing and supply chain. Together with an improved manufacturing process, we are confident in our ability to meet patient demand with timely delivery,” according to a Novartis spokesperson.

The spokesperson also pointed out that the company has continuously incorporated process improvements that have significantly increased manufacturing capacity and success rates for patients in need of CAR T cells.

“Data presented at [the] American Society of Hematology annual meeting in 2021 showed the Novartis Morris Plains facility, our flagship CAR T manufacturing site, had commercial manufacturing and shipping success rates of 96% and 99%, respectively, between January and August 2021,” according to the spokesperson.

Legend and Janssen, the companies behind Carvykti, one of the two approved cell products for myeloma, which launched earlier in 2022, said that they have continued to activate certified treatment centers in a phased approach that will enable them to expand availability throughout 2022 and beyond.

“This phased approach was designed to ensure the highest level of predictability and reliability for the patient and the certified treatment centers,” the spokesperson said. “We understand the urgency for patients in need of Carvyki and are committed to doing everything we can to accelerate our ability to deliver this important cell therapy in a reliable and timely manner.”

With regard to the industry-wide supply shortage of lentivirus, Legend and Janssen say they have put in place multiple processes to address the shortage, “including enhancing our own internal manufacturing capabilities of this essential drug substance, to ensure sufficient and sustained supply.”
 

Incredibly exciting potential

Given the immense potential of CAR T-cell therapy, the supply shortage that myeloma patients are experiencing is all the more poignant and distressing. While not everyone benefits, some patients for whom every other therapy failed and who were facing hospice have had dramatic results.

“Incredibly exciting with unbelievable potential” was how one expert described these new therapies when the first product was about to enter the marketplace. Since then, six CAR T-cell therapies have received regulatory approval for an ever-increasing range of hematologic malignancies.

But these CAR T-cell therapies have their own set of adverse events, which can be serious and even life-threatening. In addition, not all patients become cancer free, although long-term data are impressive.

A study that included one of the longest follow-ups to date was reported at the 2020 annual meeting of the American Society of Clinical Oncology. The researchers reported that remissions lasted over 9 years for patients with relapsed/refractory B-cell lymphoma or chronic lymphocytic leukemia who underwent treatment with Kite’s axicaptagene cilleucel (Yescarta). This review included 43 patients and showed an overall remission rate of 76%. Complete remission was achieved for 54% of patients, and partial remission was achieved for 22%.

The results with CAR T-cell therapy in multiple myeloma are not quite as impressive, but even so, the clinical data that supported the approval of Abecma showed that a third of patients, who had previously received a median of six prior therapies, achieved a complete response.

At the time of the Abecma approval, the lead investigator of the study, Nikhil Munshi, MD, of Dana-Farber Cancer Institute, Boston, commented: “The results of this trial represent a true turning point in the treatment of this disease. In my 30 years of treating myeloma, I have not seen any other therapy as effective in this group of patients.”

It was 2 a.m. And Rebecca Shatsky, MD, could not sleep.

The breast oncologist was thinking about a patient of hers with metastatic cancer.

The patient’s disease had been asymptomatic for some time. Then without warning, her cancer suddenly exploded. Her bone marrow was failing, and her liver was not far behind.

Dr. Shatsky had a treatment plan ready to go but still, she felt uneasy.

“I had to be honest with her that I didn’t know if this plan would work,” says Dr. Shatsky, a medical oncologist at University of California, San Diego (UCSD).

That night, after visiting the patient in the hospital, Dr. Shatsky lay awake going over her next move, making sure it was the right one and hoping it would help keep the disease at bay.

“It’s so much pressure when someone is depending on you to make life or death decisions,” Dr. Shatsky said.

And in the quiet hours of night, these concerns grow louder.

Dr. Shatsky is not alone. Oncologists face difficult decisions every day, and many wrestle with these choices long after their day in the clinic is over.

“There’s no off button,” says Aaron Goodman, MD, a hematologist at UCSD Health who goes by “Papa Heme” on Twitter. “I’m always thinking about my patients. Constantly.”

The public rarely gets a glimpse of these private moments. On occasion, oncologists will share a personal story, but more often, insights come from broad research on the ethical, emotional, and psychological toll of practicing medicine.

Many oncologists carry this baggage home with them because they have no other option.

“There is simply no time to process the weight of the day when I’ve got seven more patients who need my full attention before lunch,” Mark Lewis, MD, director, department of gastrointestinal oncology, Intermountain Healthcare, Salt Lake City, Utah. “That is why my processing happens outside of the office, when my brain can be quiet.”
 

What am I missing?

Dr. Goodman recognizes the gravity of each decision he makes. He pores over every detail of a patient’s scans, lab results, history, and symptoms.

But no matter how many times he checks and rechecks, one question nags at him: What am I missing?

For Dr. Goodman, this exhaustive level of attention is worth it.

“When errors are made, it’s someone’s life,” Dr. Goodman said. “Nothing would have prepared me for this responsibility. Until it lies on you, it’s impossible to understand how much trust patients put into us.”

That trust becomes most apparent for Dr. Goodman when facing a decision about how to treat a patient with acute myeloid leukemia who’s in remission.

Give more chemotherapy to root out the leukemia cells still lurking in the body, and the patient faces a high risk of the cancer returning. Pick stem cell transplant, and the chance of being cured goes up significantly, but the patient could also die within 100 days of the transplant.

“All together, the data show I’m helping patients with a transplant, but for the individual, I could be causing harm. Someone could be living less because of a decision I made,” Dr. Goodman said.

For patients with advanced cancer, oncologists may need to think several moves ahead. Mapping out a patient’s treatment options can feel like a game of chess. Dr. Shatsky is always trying to anticipate how the tumor will behave, what is driving it, and how lifestyle factors may influence a patient’s response in the present and the future.

“It is a mind game,” she says. “Like in chess, I try to outsmart my opponent. But with advanced cancer, there are not necessarily clear-cut guidelines or one way to manage the disease, and I have to do the best I can with drugs I have.”

That’s the art of oncology: Balancing the many knowns and unknowns of a person’s cancer alongside the toxicities of treatment and a patient’s hopes and goals.

Throughout the year, Don Dizon, MD, will see a number of patients with advanced disease. In these instances, the question he often wrestles with is if the patient can’t be cured, whether more treatment will just cause greater harm.

Dr. Dizon recently faced this dilemma with an older patient with metastatic disease who had not done well with an initial treatment regimen. After outlining the risks for more chemotherapy, he explained one option would be to forgo it and simply treat her symptoms.

“It’s an impossible choice,” says Dr. Dizon, director of women’s cancers at Lifespan Cancer Institute and director of medical oncology at Rhode Island Hospital, Providence.

Chemotherapy can provide symptom relief, but it can also be toxic – and patients may be so frail, they can die from more therapy.

“I told my patient, if in your heart, you want to try more therapy, that’s okay. But it’s also okay if you don’t,” Dr. Dizon recalled.

Her response: “You’re supposed to give me the answer.”

However, for patients approaching the end of life, there often is no right answer. 

“It’s part of the discomfort you live with as a patient and oncologist, and when I leave the clinic, that’s one thing that follows me home,” Dr. Dizon said. “At the end of the day, I need to look in the mirror and know I did the best I could.”
 

The difficult conversation

Every Sunday, Dr. Lewis feels the weight of the week ahead. He and his wife, a pediatrician, call it the “Sunday scaries.”

It’s when Dr. Lewis begins thinking about the delicate conversations to come, rehearsing how he’s going to share the news that a person has advanced cancer or that a cancer, once in remission, has returned.

“Before the pandemic, I had 36 people come to a visit where I delivered some very heavy news and it became a Greek chorus of sobbing,” he recalls.

For every oncologist, delivering bad news is an integral part of the job. But after spending months, sometimes years, with a patient and the family, Dr. Lewis knows how to take the temperature of the room – who will likely prefer a more blunt style and who might need a gentler touch.

“The longer you know a patient and family, the better you can gauge the best approach,” Dr. Lewis said. “And for some, you know it’ll be complete devastation no matter what.”

When Jennifer Lycette, MD, prepares for a difficult conversation, she’ll run down all the possible ways it could go. Sometimes her brain will get stuck in a loop, cycling through the different trajectories on repeat.

“For years, I didn’t know how to cope with that,” said Dr. Lycette, medical director at Providence Oncology and Hematology Care Clinic in Seaside, Ore. “I wasn’t taught the tools to cope with that in my medical training. It took midcareer professional coaching that I sought out on my own to learn to remind myself that no matter what the person says, I have the experience and skill set to handle what comes next and to simply be present in the moment with the patient.”

The question that now sits with Dr. Lycette hours after a visit is what she could have done better. She knows from experience how important it is to choose her words carefully.

Early in her career, Dr. Lycette had a patient with stage IV cancer who wanted to know more about the death process. Because most people ask about pain, she assured him that he likely wouldn’t experience too much pain with his type of cancer.

“It will probably be like falling asleep,” said Dr. Lycette, hoping she was offering comfort. “When I saw him next, he told me he hadn’t slept.”

He was afraid that if he did, he wouldn’t wake up.

In that moment, Dr. Lycette realized the power that her words carry and the importance of trying to understand the inner lives of her patients.
 

Life outside the clinic

Sometimes an oncologist’s late-night ruminations have little to do with cancer itself.

Manali Patel, MD, finds herself worrying if her patients will have enough to eat and whether she will be able to help.

“I was up at 3 a.m. one morning, thinking about how we’re going to fund a project for patients from low-income households who we discovered were experiencing severe food insecurity – what grants we need, what foundations we can work with,” said Dr. Patel, a medical oncologist at Stanford Hospital and Clinics and the VA Palo Alto Health Care System in California.

The past few years of the pandemic have added a new layer of worry for Dr. Patel.

“I don’t want my patients to die from a preventable virus when they’ve already been through so much suffering,” Dr. Patel said.

This thought feeds worries about how her actions outside the clinic could unintentionally harm her patients. Should she go to a big medical conference? A family gathering? The grocery store?

“There are some places you can’t avoid, but these decisions have caused a lot of strife for me,” she said. “The health and safety of our patients – that’s in our wheelhouse – but so many of the policies are outside of our control.”
 

The inevitable losses and the wins

For patients with metastatic disease, eventually the treatment options will run out.

Dr. Shatsky likes to be up front with patients about that reality: “There will come a day when I will tell you there’s nothing more I can do, and you need to trust that I’m being honest with you and that’s the truth.”

For Dr. Goodman, the devastation that bad news brings patients and families is glaring. He knows there will be no more normalcy in their lives.

“I see a lot of suffering, but I know the suffering happens regardless of whether I see it or not,” Dr. Goodman said.

That’s why holding on to the victories can be so important. Dr. Goodman recalled a young patient who came to him with a 20-cm tumor and is now cured. “Had I not met that individual and done what I had done, he’d be dead, but now he’s going to live his life,” Dr. Goodman said. “But I don’t wake up at 2 a.m. thinking about that.”

Dr. Shatsky gets a lot of joy from the wins – the patients who do really well, the times when she can help a friend or colleagues – and those moments go a long way to outweigh the hurt, worry, and workload.

When dealing with so much gray, “the wins are important, knowing you can make a difference is important,” Dr. Dizon said.

And there’s a delicate balance.

“I think patients want an oncologist who cares and is genuinely invested in their outcomes but not someone who is so sad all the time,” Dr. Lewis said. “When I lose a patient, I still grieve each loss, but I can’t mourn every patient’s death like it’s a family member. Otherwise, I’d break.”

What would you do if you had terminal cancer?

Dr. Dizon recalled how a friend handled the news. She went home and made dinner, he said.

Ultimately, she lived for many years. She saw her kids get married, met her first grandchild, and had time to prepare, something not everyone gets the chance to do.

That’s why it’s important to “do what you normally do as long as you can,” Dr. Dizon said. “Live your life.”

It was 2 a.m. And Rebecca Shatsky, MD, could not sleep.

The breast oncologist was thinking about a patient of hers with metastatic cancer.

The patient’s disease had been asymptomatic for some time. Then without warning, her cancer suddenly exploded. Her bone marrow was failing, and her liver was not far behind.

A version of this article first appeared on Medscape.com.

Ten years ago, Stephan Grupp, MD, PhD, plunged into an unexplored area of pediatric cancer treatment with a 6-year-old patient for whom every treatment available for her acute lymphoblastic leukemia (ALL) had been exhausted.

Dr. Grupp, a pioneer in cellular immunotherapy at Children’s Hospital of Philadelphia, had just got the green light to launch the first phase 1 trial of chimeric antigen receptor (CAR) T-cell therapy for children.

“The trial opened at the absolute last possible moment that it could have been helpful to her,” he said in an interview. “There was nothing else to do to temporize her further. ... It had to open then or never.”

The patient was Emily Whitehead, who has since become a poster girl for the dramatic results that can be achieved with these novel therapies. After that one CAR T-cell treatment back in 2012, she has been free of her leukemia and has remained in remission for more than 10 years.

Dr. Grupp said that he is, at last, starting to use the “cure” word.

“I’m not just a doctor, I’m a scientist – and one case isn’t enough to have confidence about anything,” he said. “We wanted more patients to be out longer to be able to say that thing which we have for a long time called the ‘c word.’

“CAR T-cell therapy has now been given to hundreds of patients at CHOP, and – we are unique in this – we have a couple dozen patients who are 5, 6, 7, 9 years out or more without further therapy. That feels like a cure to me,” he commented.
 

First patient with ALL

Emily was the first patient with ALL to receive the novel treatment, and also the first child.

There was a precedent, however. After having been “stuck” for decades, the CAR T-cell field had recently made a breakthrough, thanks to research by Dr. Grupp’s colleague Carl June, MD, and associates at the University of Pennsylvania, Philadelphia. By tweaking two key steps in the genetic modification of T cells, Dr. June’s team had successfully treated three adults with chronic lymphocytic leukemia (CLL), two of whom were in complete remission.

But using the treatment for a child and for a different type of leukemia was a daunting prospect. Dr. Grupp said that he was candid with Emily’s parents, Tom and Kari Whitehead, emphasizing that there are no guarantees in cancer treatment, particularly in a phase 1 trial.

But the Whiteheads had no time to waste and nowhere else to turn. Her father, Tom, recalled saying: “This is something outside the box, this is going to give her a chance.”

Dr. Grupp, who described himself as being “on the cowboy end” of oncology care, was ready to take the plunge.

Little did any of them know that the treatment would make Emily even sicker than she already was, putting her in intensive care. But thanks to a combination of several lucky breaks and a lot of brain power, she would make a breathtakingly rapid recovery.
 

The ‘magic formula’

CAR T-cell therapy involves harvesting a patient’s T cells and modifying them in the lab with a chimeric antigen receptor to target CD19, a protein found on the surface of ALL cancer cells.

Before the University of Pennsylvania team tweaked the process, clinical trials of the therapy yielded only modest results because the modified T cells “were very powerful in the short term but had almost no proliferative capacity” once they were infused back into the patient, Dr. Grupp explained.

“It does not matter how many cells you give to a patient, what matters is that the cells grow in the patient to the level needed to control the leukemia,” he said.

Dr. June’s team came up with what Dr. Grupp calls “the magic formula”: A bead-based manufacturing process that produced younger T-cell phenotypes with “enormous” proliferative capacity, and a lentiviral approach to the genetic modification, enabling prolonged expression of the CAR-T molecule.

“Was it rogue? Absolutely, positively not,” said Dr. Grupp, thinking back to the day he enrolled Emily in the trial. “Was it risky? Obviously ... we all dived into this pool without knowing what was under the water, so I would say, rogue, no, risky, yes. And I would say we didn’t know nearly enough about the risks.”
 

Cytokine storm

The gravest risk that Dr. Grupp and his team encountered was something they had not anticipated. At the time, they had no name for it.

The three adults with CLL who had received CAR T-cell therapy had experienced a mild version that the researchers referred to as “tumor lysis syndrome”.

But for Emily, on day 3 of her CAR T-cell infusion, there was a ferocious reaction storm that later came to be called cytokine release syndrome.

“The wheels just came off then,” said Mr. Whitehead. “I remember her blood pressure was 53 over 29. They took her to the ICU, induced a coma, and put her on a ventilator. It was brutal to watch. The oscillatory ventilator just pounds on you, and there was blood bubbling out around the hose in her mouth.

“I remember the third or fourth night, a doctor took me in the hallway and said, ‘There’s a one-in-a-thousand chance your daughter is alive when the sun comes up,’” Mr. Whitehead said in an interview. “And I said: ‘All right, I’ll see you at rounds tomorrow, because she’ll still be here.’ ”

“We had some vague notion of toxicity ... but it turned out not nearly enough,” said Dr. Grupp. The ICU “worked flat out” to save her life. “They had deployed everything they had to keep a human being alive and they had nothing more to add. At some point, you run out of things that you can do, and we had run out.”
 

On the fly

It was then that the team ran into some good luck. The first break was when they decided to look at her cytokines. “Our whole knowledge base came together in the moment, on the fly, at the exact moment when Emily was so very sick,” he recalled. “Could we get the result fast enough? The lab dropped everything to run the test.”

They ordered a broad cytokine panel that included 30 analytes. The results showed that a number of cytokines “were just unbelievably elevated,” he said. Among them was interleukin-6.

“IL-6 isn’t even made by T cells, so nobody in the world would have guessed that this would have mattered. If we’d ordered a smaller panel, it might not even have been on it. Yet this was the one cytokine we had a drug for – tocilizumab – so that was chance. And then, another chance was that the drug was at the hospital, because there are rheumatology patients who get it.

“So, we went from making the determination that IL-6 was high and figuring out there was a drug for it at 3:00 o’clock to giving the drug to her at 8:00 o’clock, and then her clinical situation turned around so quickly – I mean hours later.”

Emily woke up from a 14-day medically induced coma on her seventh birthday.

Eight days later, her bone marrow showed complete remission. “The doctors said, ‘We’ve never seen anyone this sick get better any faster,’ ” Mr. Whitehead said.

She had already been through a battery of treatments for her leukemia. “It was 22 months of failed, standard treatment, and then just 23 days after they gave her the first dose of CAR T-cells that she was cancer free,” he added.
 

Talking about ‘cure’

Now that Emily, 17, has remained in remission for 10 years, Dr. Grupp is finally willing to use the word “cure” – but it has taken him a long time.

Now, he says, the challenge from the bedside is to keep parents’ and patients’ expectations realistic about what they see as a miracle cure.

“It’s not a miracle. We can get patients into remission 90-plus percent of the time – but some patients do relapse – and then there are the risks [of the cytokine storm, which can be life-threatening].

“Right now, our experience is that about 12% of patients end up in the ICU, but they hardly ever end up as sick as Emily ... because now we’re giving the tocilizumab much earlier,” Dr. Grupp said.
 

Hearing whispers

Since their daughter’s recovery, Tom and Kari Whitehead have dedicated much of their time to spreading the word about the treatment that saved Emily’s life. Mr. Whitehead testified at the Food and Drug Administration’s advisory committee meeting in 2017 when approval was being considered for the CAR T-cell product that Emily received. The product was tisagenlecleucel-T (Novartis); at that meeting, there was a unanimous vote to recommend approval. This was the first CAR T cell to reach the market.

As cofounders of the Emily Whitehead Foundation, Emily’s parents have helped raise more than $2 million to support research in the field, and they travel around the world telling their story to “move this revolution forward.”

Despite their fierce belief in the science that saved Emily, they also acknowledge there was luck – and faith. Early in their journey, when Emily experienced relapse after her initial treatments, Mr. Whitehead drew comfort from two visions, which he calls “whispers,” that guided them through several forks in the road and through tough decisions about Emily’s treatment.

Several times the parents refused treatment that was offered to Emily, and once they had her discharged against medical advice. “I told Kari she’s definitely going to beat her cancer – I saw it. I don’t know how it’s going to happen, but we’re going to be in the bone marrow transplant hallway [at CHOP] teaching her to walk again. I know a lot of doctors don’t want to hear anything about ‘a sign,’ or what guided us, but I don’t think you have to separate faith and science, I think it takes everything to make something like this to happen.”
 

Enduring effect

The key to the CAR T-cell breakthrough that gave rise to Emily’s therapy was cell proliferation, and the effect is enduring, beyond all expectations, said Dr. Grupp. The modified T cells are still detectable in Emily and other patients in long-term remission.

“The fundamental question is, are the cells still working, or are the patients cured and they don’t need them?” said Dr. Grupp. “I think it’s the latter. The data that we have from several large datasets that we developed with Novartis are that, if you get to a year and your minimal residual disease testing both by flow and by next-generation sequencing is negative and you still have B-cell aplasia, the relapse risk is close to zero at that point.”

While it’s still not clear if and when that risk will ever get to zero, Emily and Dr. Grupp have successfully closed the chapter.

“Oncologists have different notions of what the word ‘cure’ means. If your attitude is you’re not cured until you’ve basically reached the end of your life and you haven’t relapsed, well, that’s an impossible bar to hit. My attitude is, if your likelihood of having a disease recurrence is lower than the other risks in your life, like getting into your car and driving to your appointment, then that’s what a functional cure looks like,” he said.

“I’m probably the doctor that still sees her the most, but honestly, the whole conversation is not about leukemia at all. She has B-cell aplasia, so we have to treat that, and then it’s about making sure there’s no long-term side effects from the totality of her treatment. Generally, for a patient who’s gotten a moderate amount of chemotherapy and CAR T, that should not interfere with fertility. Has any patient in the history of the world ever relapsed more than 5 years out from their therapy? Of course. Is that incredibly rare? Yes, it is. You can be paralyzed by that, or you can compartmentalize it.”

As for the Whiteheads, they are focused on Emily’s college applications, her new driver’s license, and her project to cowrite a film about her story with a Hollywood filmmaker.

Mr. Whitehead said the one thing he hopes clinicians take away from their story is that sometimes a parent’s instinct transcends science.

Ten years ago, Stephan Grupp, MD, PhD, plunged into an unexplored area of pediatric cancer treatment with a 6-year-old patient for whom every treatment available for her acute lymphoblastic leukemia (ALL) had been exhausted.

Dr. Grupp, a pioneer in cellular immunotherapy at Children’s Hospital of Philadelphia, had just got the green light to launch the first phase 1 trial of chimeric antigen receptor (CAR) T-cell therapy for children.

“The trial opened at the absolute last possible moment that it could have been helpful to her,” he said in an interview. “There was nothing else to do to temporize her further. ... It had to open then or never.”

The patient was Emily Whitehead, who has since become a poster girl for the dramatic results that can be achieved with these novel therapies. After that one CAR T-cell treatment back in 2012, she has been free of her leukemia and has remained in remission for more than 10 years.

Dr. Grupp said that he is, at last, starting to use the “cure” word.

“I’m not just a doctor, I’m a scientist – and one case isn’t enough to have confidence about anything,” he said. “We wanted more patients to be out longer to be able to say that thing which we have for a long time called the ‘c word.’

“CAR T-cell therapy has now been given to hundreds of patients at CHOP, and – we are unique in this – we have a couple dozen patients who are 5, 6, 7, 9 years out or more without further therapy. That feels like a cure to me,” he commented.
 

First patient with ALL

Emily was the first patient with ALL to receive the novel treatment, and also the first child.

There was a precedent, however. After having been “stuck” for decades, the CAR T-cell field had recently made a breakthrough, thanks to research by Dr. Grupp’s colleague Carl June, MD, and associates at the University of Pennsylvania, Philadelphia.

A new, industry-funded consensus statement from an international team of hematologists, oncologists, and cardio-oncologists urges caution regarding the cardiac risks of Bruton tyrosine kinase inhibitors (BTKis) in treating chronic lymphocytic leukemia (CLL).

The report discourages the use of the drugs in patients with heart failure, and it specifies that ibrutinib should be avoided in cases of ventricular fibrillation. The consensus statement appeared in the journal Blood Advances.

However, a physician who studies the intersection of cardiology and oncology questioned the report's methodology and said that it goes too far in its warnings about the use of BTKis. Also, the report is funded by AstraZeneca, which produces acalabrutinib, a rival BTKi product to ibrutinib.

“BTK inhibitors have revolutionized treatment outcomes and strategies in both the upfront and refractory CLL disease settings. Led by ibrutinib, the drugs are associated with dramatic improvements in long-term survival and disease outcomes for most CLL patients,” report co-author and cardiologist Daniel Addison, MD, co-director of the cardio-oncology program at the Ohio State University, said in an interview. “The main cardiac concerns are abnormal heart rhythms, high blood pressure, and heart weakness. It is not completely clear at this time why these things develop when patients are treated with these important drugs.”

For the new consensus statement, colleagues met virtually and examined peer-reviewed research. “Generally, this statement reflects available knowledge from cancer clinical trials,” Dr. Addison said. “Because of the design of these trials, cardiac analyses were secondary analyses. In terms of clinic use, this should be balanced against a large number of heart-focused retrospective examinations specifically describing the cardiac effects of these drugs. Most of the available heart-focused studies have not been prospective trials. Primary outcome heart-focused trials with BTK inhibitors are needed. This statement acknowledges this.”

The report recommends that all patients under consideration for BTKi therapy undergo electrocardiograms and blood pressure measurement, and it states that echocardiograms are appropriate for patients with heart disease or at high risk. Patients under 70 without risk factors may take ibrutinib, acalabrutinib, or zanubrutinib, while the latter two drugs are “generally preferred” in patients with established heart disease, well-controlled atrial fibrillation (AFib), hypertension, heart failure, or valvular heart disease.

The authors noted: “If the patient has difficult-to-manage AF[ib], recent acute coronary syndromes, or difficult to control heart failure, alternatives to BTKi treatment, including venetoclax, should be considered.”

As for patients with heart failure, the authors wrote that BTKis should be avoided, “but this is a relative contraindication, not an absolute one.” Ibrutinib should definitely be avoided because of the risk of AFib.

Finally, the authors stated that “the use of BTKis, especially ibrutinib, should be avoided in patients with a history of ventricular arrhythmias and cardiac arrest. Ibrutinib has been shown to increase the incidence of ventricular arrhythmias and sudden cardiac death. Although data are not yet available regarding whether second-generation BTKis [acalabrutinib or zanubrutinib] are also associated with these events, a Bcl-2 antagonist is preferred to any BTKi in these patients.”

Darryl P. Leong, MBBS, PhD, MPH, director of the cardio-oncology program at McMaster University, Hamilton, Ont., and Hamilton Health Sciences, said in an interview that the consensus statement has important limitations.

“The data extracted were not standardized. The authors of the original research were not contacted to provide data that might have been informative,” he said. “Finally and perhaps most importantly, I am uncertain that the quality of the data on which recommendations are made was well evaluated or described.”

Specifically, Dr. Leong said the report’s conclusions about heart failure and arrhythmias are not “necessarily well-supported by the evidence.”

He added: “While there is some evidence to suggest that BTKIs may increase heart failure risk, ibrutinib leads to substantial reductions in mortality. It is a large extrapolation to accept that a mostly theoretic risk of heart failure –with modest supporting empiric data – should outweigh proven reductions in death.”

As for the recommendation against the use of ibrutinib in patients with ventricular arrhythmias and cardiac arrest, he said the evidence cited by the report – an analysis of adverse event data prompted by a case report and a retrospective analysis – is limited. “The statement that ibrutinib increases the risk of ventricular arrhythmias and sudden death is more of a hypothesis at present, and the evidence to support this hypothesis is far from conclusive.”

As for the future, report co-author Dr. Addison said that “additional prospective and lab-based studies of these drugs are needed to guide how to best manage their cardiac effects in the future. This will be critical, as the use of these drugs continues to rapidly expand. Currently, we do not know a lot about why these heart issues really happen.”

The study was funded by AstraZeneca. Several authors reported multiple disclosures. Dr. Addison disclosed funding from AstraZeneca. Dr. Leong reported consulting and speaker fees from Janssen, maker of ibrutinib, as well as AstraZeneca.

Just before he took a call from a reporter asking about the impact of drug shortages in hematology, Bill Greene, PharmD, chief pharmaceutical officer at St. Jude Children’s Research Hospital, had spent an hour on the phone overseeing his institution’s response to a hematology drug shortage. The chemotherapy drug fludarabine, used to treat chronic lymphocytic leukemia, was in short supply.

“There are 5 different manufacturers, but none of them have had drug available over the past 2 weeks,” Dr. Greene said. “We’re trying to chase some emergency supplies to be able to continue treatment for patients who’ve had their treatments initiated and planned.”

Over the past several years, this predicament has become common at hematology clinics across the country. In fact, management of scarce medication resources has become a significant part of Dr. Greene’s workload these days, as critical drugs fail to show up on time or manufacturer supplies run low at his hospital in Memphis.

This shortage of hematology drugs got a new dose of national attention, thanks to a recent episode of CBS News’ “60 Minutes.” Through interviews with physicians and parents of children who suddenly could not get vital medications, the report highlighted the recent shortage of another leukemia drug, vincristine.

“As a cancer mom, we shouldn’t be fighting for our children to get a drug that is needed,” Cyndi Valenta was quoted as saying. She recalled that when the shortage began in 2019, her 13-year-old son, a leukemia patient at Loma Linda (Calif.) University Hospital, felt frightened. Ms. Valenta said she felt a “gut-wrenching feeling of just fear and anger.” They were finally able to get doses of the drug after launching a social media campaign.

Such drug shortages are especially widespread in oncology and hematology, according to a survey of oncology pharmacists at 68 organizations nationwide. Published in the May 2022 issue of Oncology Practice, the study showed that 63% of institutions reported one or more drug shortages every month, with a 34% increase in 2019, compared with 2018. Treatment delays, reduced doses, or alternative regimens were reported by 75% of respondents, the authors wrote.

The pharmacists surveyed between May 2019 and July 2020 were asked about the three most hard-to-get chemotherapy and supportive care agents. Vincristine topped the list, followed by vinblastine, IVIG, leucovorin, and BCG, as well as difficult-to-obtain ropine, erwinia asparaginase, etoposide, and leuprolide. Several of these drugs are used to treat conditions such as lymphoma and leukemia.

Eighty-two percent of respondents reported shortages of decitabine (IV), often used as part of a cocktail with vinblastine and other drugs to treat Hodgkin lymphoma.

The reasons for drug shortages are varied. The CBS News report declared that “pharmaceutical companies have stopped producing many life-saving generic drugs because they make too little profit,” and it suggested that the federal government isn’t doing enough.

But government action actually might be making a difference. According to the FDA, the number of new drug shortages has fallen dramatically from 250 in 2011 to 41 in 2021, and the number of prevented drug shortages rose from nearly 200 to more than 300 over that same period. Still, the number of ongoing drug shortages has risen from around 40 in 2017 to about 80 in 2021.

Reasons for the paucity of certain drugs are often unclear. In a June 12, 2022 post, for example, the American Society of Health-System Pharmacists’ drug shortage database noted that the chemotherapy drug fludarabine was in short supply and provided details about when some of the 5 manufacturers expected to have it available. (This is the shortage that Dr. Greene was trying to manage.) But 4 of the 5 manufacturers “did not provide a reason,” and the fifth blamed manufacturing delays.

“There’s a lot of closely held trade secrets that hinder the ability to share good information,” said Dr. Greene. To make things more complicated, shipping times are often unreliable. “The product doesn’t show up today, we place another order. Sometimes it will show up tomorrow, sometimes it doesn’t,” he said. “If you’re not tracking it carefully, you deplete your own supply.”

Patients’ families have grown used to dealing with drug shortages, and “they’re less quick to blame personnel at our institution.”

How can hematologists cope with this issue? “The best thing in the immediate term is to advocate for their hospital to have a pharmacist dedicated to shortage monitoring and taking proactive steps to obviate shortages,” hematologist/oncologist Andrew Hantel, MD, an instructor at Dana-Farber Cancer Institute, Harvard Medical School, Boston, said in an interview.

“We have ongoing communications with other large cancer centers and the FDA to recognize shortages early and develop plans to make sure we stay ahead of them,” Dr. Hantel said. “Most often this involves assessing supply, use rates, alternative manufacturers, and additional measures the Food and Drug Administration can take (for example, importation), and occasionally working with clinical teams to see if other medications are feasible alternatives.”

If a drug is unavailable, it can also be helpful to discuss alternative approaches. “We did not have any frank shortages of vincristine,” Dr. Hantel said, “but we did focus on conservation measures and considered different ethically appropriate ways to distribute vincristine if there was a point at which we did not have enough for everyone who needed it.”

If a drug is in short supply, options can include delaying treatment, giving an alternative, or providing the rest of the regimen without the scarce drug, he said. In a 2021 report in The Lancet Hematology, Dr. Hantel and his colleagues offered “model solutions for ethical allocation during cancer medicine shortages.”

The authors of the May 2022 drug-shortage report highlighted an alternative regimen in hematology. They noted that manufacturing delays have limited the supply of dacarbazine, used for Hodgkin lymphoma. Due to the current shortages, they wrote, clinicians are considering the use of escalated bleomycin, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone, replacing dacarbazine with procarbazine and using the doxorubicin, bleomycin, vinblastine, procarbazine, and prednisone regimen, or replacing dacarbazine with cyclophosphamide.

Dr. Greene emphasized the importance of tracking the news and the drug shortage websites run by the FDA and the American Society of Health-System Pharmacists.

It’s also crucial to have a good relationship with your wholesaler, he added, and to communicate about these problems within your facility. At his hospital, the pharmaceutical staff holds a multi-disciplinary meeting at least weekly to discuss the supply of medications. As he put it, “it’s a challenging environment.”

The Food and Drug Administration issued a warning June 30 that the cancer drug duvelisib (Copiktra, Verastem Inc.), a PI3 kinase inhibitor, may increase the risk of death and serious side effects.

Duvelisib was approved in 2018 to treat adults with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) who had received at least two prior therapies that did not work or stopped working.

However, more recent 5-year overall survival results from the randomized phase 3 DUO clinical trial found a possible increased risk of death with duvelisib compared with another drug used to treat leukemia and lymphoma, according to an FDA Drug Safety Communication.

“The trial also found Copiktra was associated with a higher risk of serious side effects, including infections, diarrhea, inflammation of the intestines and lungs, skin reactions, and high liver enzyme levels in the blood,” states the warning, which advises prescribers to weigh the risks and benefits of continued use versus use of other treatments.

More specifically, median 5-year overall survival among 319 patients with CLL or SLL in the DUO trial was 52.3 months with duvelisib versus 63.3 months with the monoclonal antibody ofatumumab (hazard ratio, 1.09 overall and 1.06 among patients who received at least two prior lines of therapy).

Serious adverse events of grade 3 or higher were also more common in those treated with duvelisib.

Of note, in April, the FDA also announced it was withdrawing approval of the relapsed or refractory follicular lymphoma indication for duvelisib, following a voluntary request by the drug manufacturer, Secura Bio Inc.

A public meeting will be scheduled to discuss the findings of the trial and whether the drug should continue to be prescribed.

This FDA warning follows the agency’s June 1 withdrawal of approval for umbralisib (Ukoniq), another PI3 kinase inhibitor, following an investigation into a “possible increased risk of death.”

As reported by Medscape, umbralisib had received accelerated approval in February 2021 to treat adults with relapsed or refractory marginal zone lymphoma following at least one prior therapy and those with relapsed or refractory follicular lymphoma who had received at least three prior therapies.

“These safety findings were similar for other medicines in the same PI3 kinase inhibitor class, which were discussed at an advisory committee meeting of non-FDA experts in April 2022,” according to the FDA warning.

The FDA urges patients and health care professionals to report side effects involving duvelisib or other medicines to the FDA MedWatch program.

VIENNA – Ibrutinib and obinutuzumab combined with a three-cycle regimen of chemotherapy as a first-line treatment for fit patients with chronic lymphocytic leukemia (CLL) shows progression-free and overall survival rates that are comparable, if not higher, than those commonly reported with six-cycle regimens, new research shows.

“Overall, our data suggests that [the chemoimmunotherapy] regimen is very effective and appears superior to published six cycles of chemotherapy regimen for the same favorable risk features,” first author Dr. Nitin Jain, an associate professor in the department of leukemia at the University of Texas MD Anderson Cancer Center, Houston, told MDedge.

 Chemoimmunotherapy with fludarabine, cyclophosphamide and rituximab (FCR) has been a standard frontline treatment for young, fit patients with CLL, resulting in 10-year PFS rates above 55% in patients with mutated IGHV status, said coauthor Dr. Alessandra Ferrajoli, also of the MD Anderson Cancer Center, in presenting the findings at the European Hematology Association annual congress. 

The authors sought to investigate the efficacy of a targeted therapy combination of ibrutinib and obinutuzumab with fludarabine and cyclophosphamide (iFCG). They also sought to determine whether a three-cycle regimen of the chemotherapy, as compared to six cycles, could reduce the risk of myelodysplastic syndrome (MDS), which increases with chemotherapy in CLL patients who have mutated IGHV status.

For the phase 2 study, 45 previously untreated patients with CLL, who had mutated IGHV and an absence of del(17p)/TP53 mutation (both of which are associated with more favorable outcomes in CLL) were enrolled between March 2016 and August 2018. The patients were deemed fit for chemotherapy and had a median age of 60.

All patients were initially treated with three cycles of the iFCG regimen, and among them, 39 (87%) achieved undetectable measurable residual disease (MRD) in their bone marrow.

After the three cycles, an MRD-driven strategy was then used to determine subsequent treatment: All patients received nine courses of ibrutinib, and for those achieving complete remission (CR) or CR with incomplete count recovery (CRi) and undetectable MRD, three cycles of obinutuzumab were administered, while all others received nine additional cycles of obinutuzumab.

At completion of the 12 courses, those who still had MRD positivity continued on ibrutinib, while those with undetectable MRD discontinued ibrutinib.

By cycle six of iFCG, 40 (89%) of the patients achieved undetectable MRD. Overall, 44 of the 45 patients (98%) achieved undetectable MRD as their best response at any time during the study, with 69% of patients achieving CR/CRi. Four patients came off the study prior to cycle 12, including one death, one infection, and one patient who opted to pursue treatment locally. With a median follow-up of 59.6 months, there were no cases of CLL progression or Richter transformation and the lone death was from heart failure.

 One patient developed treatment-related myelodysplastic syndrome (MDS), and that patient has maintained normal blood counts over 38 months of monitoring and has not required MDS therapy, Dr. Ferrajoli reported.

 Over the follow-up, the six patients who were MRD positive after the completion of three cycles experienced a recurrence of MRD, defined as two consecutive values of 0.01% or higher in peripheral blood by flow cytometry, at a median of 27.2 months after stopping all therapy.

“Not unexpectedly, MRD recurrence during follow-up correlated with MRD positivity during therapy,” Dr. Ferrajoli said.

She noted that all six of the patients were being monitored, with no clinical progression or active therapy. However, with a median follow-up of 5 years, the progression-free survival (PFS) rate among the 45 patients was 97.7%, and the overall survival (OS) rate was 97.8%. Dr. Ferrajoli noted that, while the study population was clearly different, the results compare favorably with CLL clinical trial results that have previously shown a 5-year PFS of approximately 65% with FCR alone; approximately 70% with ibrutinib; and 81% with ibrutinib among patients with mutated IGHV status.

Furthermore, the rate of undetectable MRD status in mutated IGHV patients being 95% in evaluable patients in the current study is notably higher than rates of 51% through 67% reported in five other trials of CLL treatment with six cycles of FCR and with a rate of 79% in the DFCI trial of six-cycle chemotherapy plus ibrutinib.

And the current study’s undetectable MRD rate of 89% in the intention-to-treat population compares with just 13% though 40% in the five other chemotherapy trials and 79% in the DFCI trial, the authors note.

The current trial was the only one of any of their comparisons to utilize the three-cycle regimen.

Asked at the meeting about concerns of toxicities reported with obinutuzumab and chemotherapy, Dr. Ferrajoli said “the treatment was very well tolerated.”

“Myelosuppression is a concern with this combination, but we did make the use of prophylactic growth-factor mandatory in the study, so we were able to control that,” she said.

 Dr. Jain noted that, while treatment trends have moved largely to chemo-free regimens, particularly in the United States because of concerns about the MDS, the current study’s results importantly shed light on a potentially beneficial approach of just three cycles of chemotherapy.

“In Europe and the rest of the world where chemo use is still common, this regimen could be considered,” he told MDedge. “The findings show that if you still use chemo in your practice, this regimen uses 50% less chemotherapy, yet seems to give higher response rates.”

“While MDS and acute myeloid leukemia (AML) remain a concern with any chemotherapy regimen, it is possible that 50% less chemo will lead to less risk of MDS AML, but longer-term follow-up [is needed],” he said. 

 Dr. Ferrajoli reported that she has received research support from Astra-Zeneca and Beigene. Dr. Jain has received research funding and honoraria from Genentech and Pharmacyclics.

Lisocabtagene maraleucel, also known as liso-cel (Breyanzi), has been approved by the Food and Drug Administration for the second-line treatment of adult patients with relapsed or refractory large B-cell lymphoma (r/r LBCL).

This expanded indication is based on findings from the pivotal phase 3 TRANSFORM study, which showed significant and clinically meaningful improvements with CD19-directed chimeric antigen receptor T-cell immunotherapy over salvage chemotherapy followed by high-dose chemotherapy plus autologous stem cell transplant. The latter course of treatment had been the standard of care for more than 2 decades.

Data from the global, randomized, multicenter TRANSFORM study, as reported in December 2021 at the annual meeting of the American Society of Hematology, showed that second-line treatment with liso-cel in 92 patients with r/r LBCL within 12 months after first-line therapy, compared with 92 patient who received standard of care therapy, was associated with highly statistically significant and clinically meaningful improvement in event-free survival (10.1 vs. 2.3 months; hazard ratio, 0.349), complete response rate (66% vs. 39%), and progression-free survival (14.8 vs. 5.7 months; HR, 0.406).

A positive trend in overall survival was also observed (HR, 0.509 at median follow-up of 6.2 months). No new liso-cel safety signals were detected in the second-line setting.

Liso-cel was initially approved in February 2021 for the treatment of adults with LBCL, including diffuse LBCL not otherwise specified (including DLBCL arising from indolent lymphoma), high-grade B-cell lymphoma, primary mediastinal large B-cell lymphoma, and follicular lymphoma grade 3B, who have:

• Refractory disease to first-line chemoimmunotherapy or relapse within 12 months of first-line chemoimmunotherapy.
• Refractory disease to first-line chemoimmunotherapy or relapse after first-line chemoimmunotherapy and are not eligible for hematopoietic stem cell transplant because of comorbidities or age.

Liso-cel is not indicated for the treatment of patients with primary central nervous system lymphoma.

In February 2022, the FDA granted Priority Review status for a Bristol-Myers Squibb supplemental Biologics License Application (sBLA), based on the TRANSFORM study data, to expand the indication to include use after the failure of first-line therapy.

The agent “now has the potential to be a new standard of care for patients after failure of first-line therapy, offering significantly improved outcomes beyond the current mainstay of care,” Anne Kerber, the BMS senior vice president of cell therapy development, said in a press release at that time.

The European Medicines Agency has also validated a type II variation application for extension of the indication for liso-cel in this setting. Validation of the application “confirms the submission is complete and begins the EMA’s centralized review procedure,” BMS announced in a June 20, 2022, press release.

Liso-cel, which has been available only through a restricted program under a Risk Evaluation and Mitigation Strategy, includes a boxed warning regarding the risk for cytokine release syndrome (CRS) and neurologic toxicities.

The warning states that liso-cel should not be administered to patients with active infection or inflammatory disorders, and that severe or life-threatening CRS should be treated with tocilizumab with or without corticosteroids.

Patients should also be monitored for neurologic events after treatment with liso-cel, and supportive care and/or corticosteroids should be administered as needed.

Use of the targeted therapy combination of venetoclax plus obinutuzumab for fit patients with chronic lymphocytic leukemia (CLL) significantly improved progression-free survival (PFS) at 3 years, compared with standard chemoimmunotherapy, new phase 3 data show.

Adding the Bruton tyrosine kinase inhibitor ibrutinib to the two-drug combination pushed the 3-year PFS even higher, but the risk of severe adverse events may outweigh the benefits of the triple combination for some higher-risk patients.

“Time-limited targeted therapy with venetoclax plus obinutuzumab, with or without ibrutinib, is superior to chemoimmunotherapy with respect to progression-free survival,” said first author Barbara Eichhorst, MD, of the University of Cologne (Germany).

However, given higher rates of infection and other adverse events observed when adding ibrutinib, “I would say, based on this data, not to use the triple combination in clinical practice,” Dr. Eichhorst cautioned.

Dr. Eichhorst presented these late-breaking results at the European Hematology Association annual congress.

For patients considered unfit for chemoimmunotherapy, the fixed-duration therapy of venetoclax plus obinutuzumab has become standard treatment for CLL. For those deemed fit to withstand chemoimmunotherapy, this option remains the standard of care.

However, no studies have compared the targeted combination with chemoimmunotherapy for fit patients with CLL.

Dr. Eichhorst and colleagues conducted the GAIA/CLL13 trial to determine how the two- or three-drug targeted combinations stack up against standard chemoimmunotherapy for fit patients.

In the phase 3 study, 920 treatment-naive, fit patients with CLL in which there were no TP53 aberrations were randomly assigned to one of four treatment groups that each had 230 patients – standard chemoimmunotherapy or one of three time-limited venetoclax arms.

The regimen for the chemoimmunotherapy group included fludarabine, cyclophosphamide, and rituximab for those aged 65 and younger, and bendamustine and rituximab for those over 65. The patients who received venetoclax were divided into groups that received either venetoclax plus rituximab, venetoclax plus obinutuzumab, or triple therapy of venetoclax, obinutuzumab, and ibrutinib.

The median age was 61, and follow-up was just over 3 years (38.8 months). Nearly 40% of patients were in advanced Binet stages, and more than half (56%) were of unmutated immunoglobulin heavy chain gene (IgVH) status, which is associated with worse outcomes in CLL.

Compared with chemotherapy, the two-drug combination demonstrated significantly better PFS (hazard ratio, 0.32; P < .000001), as did the triple therapy (HR, 0.42; P < .001), though the venetoclax-rituximab combination did not (HR, 0.79; P = .183).

The 3-year PFS rates were highest in the triple-therapy group (90.5%), followed by the venetoclax and obinutuzumab group (87.7%). The chemoimmunotherapy (75.5%) and venetoclax plus rituximab groups (80.8%) had the lowest 3-year PFS rates.

Overall, 3-year PFS rates for patients with unmutated IgVH were slightly lower, compared with those who had mutated IgVH.

The best PFS rate was among patients who received the 3-drug combination, although one interesting caveat emerged among the under-65 subset of patients in the mutated IgVH group: the chemotherapy arm achieved a slightly better PFS rate (95%) compared with the triple-therapy arm (93.6%).

Notably, overall survival was similar among all groups; about 96% of patients were alive at 3 years.

Several adverse events were more pronounced in the triple-therapy group. The highest rate of grade 3-4 infections was among those who received ibrutinib (22.1% vs. 20.4% for chemotherapy, 11.4% for venetoclax/rituximab, and 14.9% for venetoclax/obinutuzumab). The triple-therapy group also had the highest rate of hypertension (5.6% vs. 1.4% for chemotherapy, 2.1% for venetoclax/rituximab, and 1.8% for venetoclax/obinutuzumab).

Rates of febrile neutropenia and secondary primary malignancies, however, were highest in the chemoimmunotherapy group. More than 11% of patients in the chemoimmunotherapy group had febrile neutropenia, compared with 7.8% of those who received triple therapy, 4.2% in the venetoclax/rituximab group, and 3.1% of those who received venetoclax/obinutuzumab. Almost half of patients in the chemoimmunotherapy group had secondary primary malignancies versus fewer than 30% in the other arms.

EHA President-Elect António Almeida, MD, noted that the research sheds important light on evolving treatment options for CLL.

“The first is that the triple combination appears better than the double combinations, and I think that’s an important message because of longer treatment-free remission and progression-free remissions,” Dr. Almeida, of the Hospital da Luz, Lisbon, said in an interview.

The second important message: Given the time-limited administration of the venetoclax combinations, the data show that “we can stop ibrutinib and that is safe,” he added. “That’s quite important.”

Third, the findings can help guide treatment choices. “We’ve already had an indication that obinutuzumab is better than rituximab in the CLL setting, but this again solidifies that notion,” Dr. Almeida added.

Dr. Eichhorst has relationships with Janssen, Gilead, F. Hoffmann–La Roche, AbbVie, BeiGene, AstraZeneca, MSD, Adaptive Biotechnologies, and Hexal. Dr. Almeida disclosed no relevant financial relationships.
