Multiple Myeloma

Clonal hematopoiesis of indeterminate potential (CHIP) and mosaic chromosomal alterations (mCAs) are associated with an increased risk for breast cancer, and CHIP is associated with increased mortality in patients with colon cancer, according to the authors of new research.

These findings, drawn from almost 11,000 patients in the Women’s Health Initiative (WHI) study, add further evidence that CHIP and mCA drive solid tumor risk, alongside known associations with hematologic malignancies, reported lead author Pinkal Desai, MD, associate professor of medicine and clinical director of molecular aging at Englander Institute for Precision Medicine, Weill Cornell Medical College, New York City, and colleagues.
 

How This Study Differs From Others of Breast Cancer Risk Factors

“The independent effect of CHIP and mCA on risk and mortality from solid tumors has not been elucidated due to lack of detailed data on mortality outcomes and risk factors,” the investigators wrote in Cancer, although some previous studies have suggested a link.

In particular, the investigators highlighted a 2022 UK Biobank study, which reported an association between CHIP and lung cancer and a borderline association with breast cancer that did not quite reach statistical significance.

But the UK Biobank study was confined to a UK population, Dr. Desai noted in an interview, and the data were less detailed than those in the present investigation.

“In terms of risk, the part that was lacking in previous studies was a comprehensive assessment of risk factors that increase risk for all these cancers,” Dr. Desai said. “For example, for breast cancer, we had very detailed data on [participants’] Gail risk score, which is known to impact breast cancer risk. We also had mammogram data and colonoscopy data.”

In an accompanying editorial, Koichi Takahashi, MD, PhD , and Nehali Shah, BS, of The University of Texas MD Anderson Cancer Center, Houston, Texas, pointed out the same UK Biobank findings, then noted that CHIP has also been linked with worse overall survival in unselected cancer patients. Still, they wrote, “the impact of CH on cancer risk and mortality remains controversial due to conflicting data and context‐dependent effects,” necessitating studies like this one by Dr. Desai and colleagues.
 

How Was the Relationship Between CHIP, MCA, and Solid Tumor Risk Assessed?

To explore possible associations between CHIP, mCA, and solid tumors, the investigators analyzed whole genome sequencing data from 10,866 women in the WHI, a multi-study program that began in 1992 and involved 161,808 women in both observational and clinical trial cohorts.

In 2002, the first big data release from the WHI suggested that hormone replacement therapy (HRT) increased breast cancer risk, leading to widespread reduction in HRT use.

More recent reports continue to shape our understanding of these risks, suggesting differences across cancer types. For breast cancer, the WHI data suggested that HRT-associated risk was largely driven by formulations involving progesterone and estrogen, whereas estrogen-only formulations, now more common, are generally considered to present an acceptable risk profile for suitable patients.

The new study accounted for this potential HRT-associated risk, including by adjusting for patients who received HRT, type of HRT received, and duration of HRT received. According to Desai, this approach is commonly used when analyzing data from the WHI, nullifying concerns about the potentially deleterious effects of the hormones used in the study.

“Our question was not ‘does HRT cause cancer?’ ” Dr. Desai said in an interview. “But HRT can be linked to breast cancer risk and has a potential to be a confounder, and hence the above methodology.

“So I can say that the confounding/effect modification that HRT would have contributed to in the relationship between exposure (CH and mCA) and outcome (cancer) is well adjusted for as described above. This is standard in WHI analyses,” she continued.

“Every Women’s Health Initiative analysis that comes out — not just for our study — uses a standard method ... where you account for hormonal therapy,” Dr. Desai added, again noting that many other potential risk factors were considered, enabling a “detailed, robust” analysis.

Dr. Takahashi and Ms. Shah agreed. “A notable strength of this study is its adjustment for many confounding factors,” they wrote. “The cohort’s well‐annotated data on other known cancer risk factors allowed for a robust assessment of CH’s independent risk.”
 

How Do Findings Compare With Those of the UK Biobank Study?

CHIP was associated with a 30% increased risk for breast cancer (hazard ratio [HR], 1.30; 95% CI, 1.03-1.64; P = .02), strengthening the borderline association reported by the UK Biobank study.

In contrast with the UK Biobank study, CHIP was not associated with lung cancer risk, although this may have been caused by fewer cases of lung cancer and a lack of male patients, Dr. Desai suggested.

“The discrepancy between the studies lies in the risk of lung cancer, although the point estimate in the current study suggested a positive association,” wrote Dr. Takahashi and Ms. Shah.

As in the UK Biobank study, CHIP was not associated with increased risk of developing colorectal cancer.

Mortality analysis, however, which was not conducted in the UK Biobank study, offered a new insight: Patients with existing colorectal cancer and CHIP had a significantly higher mortality risk than those without CHIP. Before stage adjustment, risk for mortality among those with colorectal cancer and CHIP was fourfold higher than those without CHIP (HR, 3.99; 95% CI, 2.41-6.62; P < .001). After stage adjustment, CHIP was still associated with a twofold higher mortality risk (HR, 2.50; 95% CI, 1.32-4.72; P = .004).

The investigators’ first mCA analyses, which employed a cell fraction cutoff greater than 3%, were unfruitful. But raising the cell fraction threshold to 5% in an exploratory analysis showed that autosomal mCA was associated with a 39% increased risk for breast cancer (HR, 1.39; 95% CI, 1.06-1.83; P = .01). No such associations were found between mCA and colorectal or lung cancer, regardless of cell fraction threshold.

The original 3% cell fraction threshold was selected on the basis of previous studies reporting a link between mCA and hematologic malignancies at this cutoff, Dr. Desai said.

She and her colleagues said a higher 5% cutoff might be needed, as they suspected that the link between mCA and solid tumors may not be causal, requiring a higher mutation rate.
 

Why Do Results Differ Between These Types of Studies?

Dr. Takahashi and Ms. Shah suggested that one possible limitation of the new study, and an obstacle to comparing results with the UK Biobank study and others like it, goes beyond population heterogeneity; incongruent findings could also be explained by differences in whole genome sequencing (WGS) technique.

“Although WGS allows sensitive detection of mCA through broad genomic coverage, it is less effective at detecting CHIP with low variant allele frequency (VAF) due to its relatively shallow depth (30x),” they wrote. “Consequently, the prevalence of mCA (18.8%) was much higher than that of CHIP (8.3%) in this cohort, contrasting with other studies using deeper sequencing.” As a result, the present study may have underestimated CHIP prevalence because of shallow sequencing depth.

“This inconsistency is a common challenge in CH population studies due to the lack of standardized methodologies and the frequent reliance on preexisting data not originally intended for CH detection,” Dr. Takahashi and Ms. Shah said.

Even so, despite the “heavily context-dependent” nature of these reported risks, the body of evidence to date now offers a convincing biological rationale linking CH with cancer development and outcomes, they added.
 

How Do the CHIP- and mCA-associated Risks Differ Between Solid Tumors and Blood Cancers?

“[These solid tumor risks are] not causal in the way CHIP mutations are causal for blood cancers,” Dr. Desai said. “Here we are talking about solid tumor risk, and it’s kind of scattered. It’s not just breast cancer ... there’s also increased colon cancer mortality. So I feel these mutations are doing something different ... they are sort of an added factor.”

Specific mechanisms remain unclear, Dr. Desai said, although she speculated about possible impacts on the inflammatory state or alterations to the tumor microenvironment.

“These are blood cells, right?” Dr. Desai asked. “They’re everywhere, and they’re changing something inherently in these tumors.”
 

Future research and therapeutic development

Siddhartha Jaiswal, MD, PhD, assistant professor in the Department of Pathology at Stanford University in California, whose lab focuses on clonal hematopoiesis, said the causality question is central to future research.

“The key question is, are these mutations acting because they alter the function of blood cells in some way to promote cancer risk, or is it reflective of some sort of shared etiology that’s not causal?” Dr. Jaiswal said in an interview.

Available data support both possibilities.

On one side, “reasonable evidence” supports the noncausal view, Dr. Jaiswal noted, because telomere length is one of the most common genetic risk factors for clonal hematopoiesis and also for solid tumors, suggesting a shared genetic factor. On the other hand, CHIP and mCA could be directly protumorigenic via conferred disturbances of immune cell function.

When asked if both causal and noncausal factors could be at play, Dr. Jaiswal said, “yeah, absolutely.”

The presence of a causal association could be promising from a therapeutic standpoint.

“If it turns out that this association is driven by a direct causal effect of the mutations, perhaps related to immune cell function or dysfunction, then targeting that dysfunction could be a therapeutic path to improve outcomes in people, and there’s a lot of interest in this,” Dr. Jaiswal said. He went on to explain how a trial exploring this approach via interleukin-8 inhibition in lung cancer fell short.

Yet earlier intervention may still hold promise, according to experts.

“[This study] provokes the hypothesis that CH‐targeted interventions could potentially reduce cancer risk in the future,” Dr. Takahashi and Ms. Shah said in their editorial.

The WHI program is funded by the National Heart, Lung, and Blood Institute; National Institutes of Health; and the Department of Health & Human Services. The investigators disclosed relationships with Eli Lilly, AbbVie, Celgene, and others. Dr. Jaiswal reported stock equity in a company that has an interest in clonal hematopoiesis.

TOPLINE: 

Teclistamab, a T-cell engager that targets B-cell maturation antigen (BCMA), improved disease activity in four patients with refractory autoimmune conditions. In a separately published case report, teclistamab treatment induced remission in a patient with refractory systemic lupus erythematosus (SLE).

BACKGROUND: 

• Chimeric antigen receptor (CAR) T cells or T-cell engagers against CD19 have been effective in small studies of patients with treatment-resistant autoimmune diseases.
• Some patients have disease rooted in long-lived plasma cells that express BCMA but not CD19, making them resistant to CD19 CAR T-cell therapy.
• Teclistamab acts on T cells through CD3 and targets plasmablasts and plasma cells through BCMA.

METHODOLOGY:

• In one case series, researchers administered teclistamab subcutaneously to four patients with autoimmune diseases resistant to more than five immunosuppressants, including rituximab.
• Patient 1 had systemic sclerosis, patient 2 had primary Sjögren disease, patient 3 had idiopathic inflammatory myositis, and patient 4 had rheumatoid arthritis.
• Researchers incrementally increased teclistamab dosage in an inpatient setting: 0.06 mg/kg on day 1, 0.3 mg/kg on day 3, and 1.5 mg/kg on day 5. Patients 2, 3, and 4 received one maintenance dose of 1.5 mg/kg after 4 weeks, and patient 1 received a 1.5-mg/kg dose after 12 weeks.
• In the single case report, the patient with SLE received a step-up dosage of teclistamab (0.06 mg/kg and 0.3 mg/kg) followed by 0.8 mg/kg on day 7. She received 1.5 mg/kg at weeks 2 and 5.

TAKEAWAY: 

• Teclistamab therapy led to significant improvements in disease activity in all four patients, with notable reductions in skin disease, arthritis, and lung function scores.
• Teclistamab therapy had a good safety profile, with no neurotoxicity or myelotoxicity and only lower-grade cytokine release syndrome reported.
• Researchers observed seroconversion of PM-Scl-75, PM-Scl-100, rheumatoid factor, and autoantibodies against mutated citrullinated vimentin and lower levels of autoantibodies ANA, MDAS, SS-A/Ro, SS-B/La, and PL-7 after treatment.
• In the separate case report, the patient reached complete drug-free remission by week 6, as defined by the Systemic Lupus Erythematosus Disease Activity Index 2000.
• The level of anti–double-stranded DNA antibodies in the patient with SLE decreased rapidly, reaching normal range by week 5 and remaining undetectable through week 16.

IN PRACTICE:

“These data show that the targeting of the plasma-cell compartment by a BCMA-targeted T-cell engager is feasible in patients with autoimmune disease. Whether such therapy results in sustained clinical remission warrants further study,” write the authors of the four-patient case series.

SOURCE: 

Melanie Hagen, MD, Friedrich Alexander University Erlangen–Nuremberg, Germany, and colleagues reported their case series online in The New England Journal of Medicine. Tobias Alexander, MD, and colleagues at Charité–Universitätsmedizin Berlin, Germany, also described their single case report in The New England Journal of Medicine.

LIMITATIONS:

The small number of patients limits the generalizability of the findings. The short duration of follow-up may not capture long-term effects and potential late-onset adverse events. The lack of a control group makes it difficult to attribute improvements solely to teclistamab therapy.

DISCLOSURES:

The four-patient case series was supported by grants from the Deutsche Forschungsgemeinschaft, Bundesministerium für Bildung und Forschung, and the European Union. The single case report was supported by grants from the Deutsche Forschungsgemeinschaft and the European Union. Several authors have disclosed financial relationships with pharmaceutical companies, including Janssen Biotech, which markets teclistamab.

Teclistamab, a T-cell engager that targets B-cell maturation antigen (BCMA), improved disease activity in four patients with refractory autoimmune conditions. In a separately published case report, teclistamab treatment induced remission in a patient with refractory systemic lupus erythematosus (SLE).

BACKGROUND: 

• Chimeric antigen receptor (CAR) T cells or T-cell engagers against CD19 have been effective in small studies of patients with treatment-resistant autoimmune diseases.
• Some patients have disease rooted in long-lived plasma cells that express BCMA but not CD19, making them resistant to CD19 CAR T-cell therapy.
• Teclistamab acts on T cells through CD3 and targets plasmablasts and plasma cells through BCMA.

METHODOLOGY:

• In one case series, researchers administered teclistamab subcutaneously to four patients with autoimmune diseases resistant to more than five immunosuppressants, including rituximab.
• Patient 1 had systemic sclerosis, patient 2 had primary Sjögren disease, patient 3 had idiopathic inflammatory myositis, and patient 4 had rheumatoid arthritis.
• Researchers incrementally increased teclistamab dosage in an inpatient setting: 0.06 mg/kg on day 1, 0.3 mg/kg on day 3, and 1.5 mg/kg on day 5. Patients 2, 3, and 4 received one maintenance dose of 1.5 mg/kg after 4 weeks, and patient 1 received a 1.5-mg/kg dose after 12 weeks.
• In the single case report, the patient with SLE received a step-up dosage of teclistamab (0.06 mg/kg and 0.3 mg/kg) followed by 0.8 mg/kg on day 7. She received 1.5 mg/kg at weeks 2 and 5.

TAKEAWAY: 

• Teclistamab therapy led to significant improvements in disease activity in all four patients, with notable reductions in skin disease, arthritis, and lung function scores.
• Teclistamab therapy had a good safety profile, with no neurotoxicity or myelotoxicity and only lower-grade cytokine release syndrome reported.
• Researchers observed seroconversion of PM-Scl-75, PM-Scl-100, rheumatoid factor, and autoantibodies against mutated citrullinated vimentin and lower levels of autoantibodies ANA, MDAS, SS-A/Ro, SS-B/La, and PL-7 after treatment.
• In the separate case report, the patient reached complete drug-free remission by week 6, as defined by the Systemic Lupus Erythematosus Disease Activity Index 2000.
• The level of anti–double-stranded DNA antibodies in the patient with SLE decreased rapidly, reaching normal range by week 5 and remaining undetectable through week 16.

IN PRACTICE:

“These data show that the targeting of the plasma-cell compartment by a BCMA-targeted T-cell engager is feasible in patients with autoimmune disease. Whether such therapy results in sustained clinical remission warrants further study,” write the authors of the four-patient case series.

SOURCE: 

Melanie Hagen, MD, Friedrich Alexander University Erlangen–Nuremberg, Germany, and colleagues reported their case series online in The New England Journal of Medicine. Tobias Alexander, MD, and colleagues at Charité–Universitätsmedizin Berlin, Germany, also described their single case report in The New England Journal of Medicine.

LIMITATIONS:

The small number of patients limits the generalizability of the findings. The short duration of follow-up may not capture long-term effects and potential late-onset adverse events. The lack of a control group makes it difficult to attribute improvements solely to teclistamab therapy.

DISCLOSURES:

The four-patient case series was supported by grants from the Deutsche Forschungsgemeinschaft, Bundesministerium für Bildung und Forschung, and the European Union. The single case report was supported by grants from the Deutsche Forschungsgemeinschaft and the European Union. Several authors have disclosed financial relationships with pharmaceutical companies, including Janssen Biotech, which markets teclistamab.

Each year in the United States, approximately 1.7 million Americans are diagnosed with a potentially lethal malignancy. Typical therapies of choice include surgery, radiation, and occasionally, toxic chemotherapy (chemo) — approaches that eliminate the cancer in about 1,000,000 of these cases. The remaining 700,000 or so often proceed to chemotherapy either immediately or upon cancer recurrence, spread, or newly recognized metastases. “Cures” after that point are rare.

I’m speaking in generalities, understanding that each cancer and each patient is unique.
 

Chemotherapy

Chemotherapy alone can cure a small number of cancer types. When added to radiation or surgery, chemotherapy can help to cure a wider range of cancer types. As an add-on, chemotherapy can extend the length and quality of life for many patients with cancer. Since chemotherapy is by definition “toxic,” it can also shorten the duration or harm the quality of life and provide false hope. The Table summarizes what chemotherapy can and cannot achieve in selected cancer types.

• Lack of response (the tumor failed to shrink).
• Progression (the cancer may have grown or spread further).
• Adverse side effects were too severe to continue.

The drugs used in second-line chemo will typically be different from those used in first line, sometimes because cancer cells can develop resistance to chemotherapy drugs over time. Moreover, the goal of second-line chemo may differ from that of first-line therapy. Rather than chiefly aiming for a cure, second-line treatment might focus on slowing cancer growth, managing symptoms, or improving quality of life. Unfortunately, not every type of cancer has a readily available second-line option.

Third-line treatment. Third-line options come into play when both the initial course of chemo (first line) and the subsequent treatment (second line) have failed to achieve remission or control the cancer’s spread. Owing to the progressive nature of advanced cancers, patients might not be eligible or healthy enough for third-line therapy. Depending on cancer type, the patient’s general health, and response to previous treatments, third-line options could include:

• New or different chemotherapy drugs compared with prior lines.
• Surgery to debulk the tumor.
• Radiation for symptom control.
• Targeted therapy: drugs designed to target specific vulnerabilities in cancer cells.
• Immunotherapy: agents that help the body’s immune system fight cancer cells.
• Clinical trials testing new or investigational treatments, which may be applicable at any time, depending on the questions being addressed.

The goals of third-line therapy may shift from aiming for a cure to managing symptoms, improving quality of life, and potentially slowing cancer growth. The decision to pursue third-line therapy involves careful consideration by the doctor and patient, weighing the potential benefits and risks of treatment considering the individual’s overall health and specific situation.

It’s important to have realistic expectations about the potential outcomes of third-line therapy. Although remission may be unlikely, third-line therapy can still play a role in managing the disease.

Navigating advanced cancer treatment is very complex. The patient and physician must together consider detailed explanations and clarifications to set expectations and make informed decisions about care.
 

Interventions to Consider Earlier

In traditional clinical oncology practice, other interventions are possible, but these may not be offered until treatment has reached the third line:

• Molecular testing.
• Palliation.
• Clinical trials.
• Innovative testing to guide targeted therapy by ascertaining which agents are most likely (or not likely at all) to be effective.

I would argue that the patient’s interests are better served by considering and offering these other interventions much earlier, even before starting first-line chemotherapy.

Molecular testing. The best time for molecular testing of a new malignant tumor is typically at the time of diagnosis. Here’s why:

• Molecular testing helps identify specific genetic mutations in the cancer cells. This information can be crucial for selecting targeted therapies that are most effective against those specific mutations. Early detection allows for the most treatment options. For example, for non–small cell lung cancer, early is best because treatment and outcomes may well be changed by test results.
• Knowing the tumor’s molecular makeup can help determine whether a patient qualifies for clinical trials of new drugs designed for specific mutations.
• Some molecular markers can offer information about the tumor’s aggressiveness and potential for metastasis so that prognosis can be informed.

Molecular testing can be a valuable tool throughout a cancer patient’s journey. With genetically diverse tumors, the initial biopsy might not capture the full picture. Molecular testing of circulating tumor DNA can be used to monitor a patient’s response to treatment and detect potential mutations that might arise during treatment resistance. Retesting after metastasis can provide additional information that can aid in treatment decisions.

Palliative care. The ideal time to discuss palliative care with a patient with cancer is early in the diagnosis and treatment process. Palliative care is not the same as hospice care; it isn’t just about end-of-life. Palliative care focuses on improving a patient’s quality of life throughout cancer treatment. Palliative care specialists can address a wide range of symptoms a patient might experience from cancer or its treatment, including pain, fatigue, nausea, and anxiety.

Early discussions allow for a more comprehensive care plan. Open communication about all treatment options, including palliative care, empowers patients to make informed decisions about their care goals and preferences.

Specific situations where discussing palliative care might be appropriate are:

• Soon after a cancer diagnosis.
• If the patient experiences significant side effects from cancer treatment.
• When considering different treatment options, palliative care can complement those treatments.
• In advanced stages of cancer, to focus on comfort and quality of life.

Clinical trials. Participation in a clinical trial to explore new or investigational treatments should always be considered.

In theory, clinical trials should be an option at any time in the patient’s course. But the organized clinical trial experience may not be available or appropriate. Then, the individual becomes a de facto “clinical trial with an n of 1.” Read this brief open-access blog post at Cancer Commons to learn more about that circumstance.

Innovative testing. The best choice of chemotherapeutic or targeted therapies is often unclear. The clinician is likely to follow published guidelines, often from the National Comprehensive Cancer Network.

These are evidence based and driven by consensus of experts. But guideline-recommended therapy is not always effective, and weeks or months can pass before this ineffectiveness becomes apparent. Thus, many researchers and companies are seeking methods of testing each patient’s specific cancer to determine in advance, or very quickly, whether a particular drug is likely to be effective.

Cancer is a tough nut to crack. Many people and organizations are trying very hard. So much is being learned. Some approaches will be effective. We can all hope.

Dr. Lundberg, editor in chief, Cancer Commons, has disclosed no relevant financial relationships.

A version of this article appeared on Medscape.com.

“Therapeutic innovations like elranatamab achieve a lasting response in 61% of patients with multiple myeloma and complete remission in 30%,” said María Victoria Mateos, MD, PhD, a consultant physician in the Hematology Service at the University Clinical Hospital of Salamanca, Spain, and president of the Spanish Society of Haematology and Haemotherapy.

“The introduction of treatments such as elranatamab (Elrexfio) is allowing patients with multiple myeloma, which is still incurable for now, to have different options and achieve long periods of remission, thus improving their survival,” she added. “This therapeutic innovation is highly effective and well tolerated in patients with relapse or refractory multiple myeloma.” The overall response rate is “up to 61%, early, deep, and long-lasting.”

In an interview with El Médico Interactivo, Dr. Mateos explained the new approaches to multiple myeloma. She highlighted the effectiveness of new treatments and reviewed the latest data on this disease, which were presented at the recent European Hematology Association Congress.
 

What is the incidence rate of multiple myeloma in the Spanish population?

Multiple myeloma has an incidence of approximately 4-5 new cases per 100,000 inhabitants per year. This means that around 3000 new cases are diagnosed each year in Spain. As with most tumors, multiple myeloma is generally slightly more common in males than females. It is the third most frequent hematologic cancer in men (1757 new cases) and women (1325 new cases), behind lymphoma and leukemias.

At what age is it most often diagnosed?

It affects older people, with recent reports indicating around 68-69 years as the median age. Although more young people are being diagnosed with multiple myeloma, analyses of how this hematologic cancer affects the general population show that it generally impacts patients over age 65 years.

What is the typical survival prognosis?

Thanks to research and therapeutic innovation, the prognosis has changed significantly over the past 20-25 years. Today, if a patient with multiple myeloma receives a diagnosis and does not exhibit poor prognostic characteristics (and this description fits approximately 70%-80% of patients with multiple myeloma), it is realistic to expect a survival exceeding 10 years. A few years ago, this outcome was unimaginable, but a significant amount of therapeutic innovation has made it possible. That’s why I emphasize that it is realistic to provide these data with such a positive outlook.

Is multiple myeloma a refractory type of cancer?

It was a refractory type of cancer. Twenty years ago, there were no treatment options, and therefore survival was around 2-3 years, because treatment mainly consisted of using alkylating agents and corticosteroids. This is what made it refractory.

With the emergence of new therapeutic innovations, patients have been responding better and their responses are lasting longer. Although there is still a group of patients, about 10%-15%, with a poor prognosis and refractory disease, those with standard risk are responding better to different therapies.

Although most patients will eventually exhaust the treatments, which until now were primarily triple-drug regimens (such as proteasome inhibitors, immunomodulators, and antiCD38 antibodies), the introduction of new therapies is extending the duration of responses.
 

Is the risk for relapse high?

It is very high, in the sense that almost all patients with multiple myeloma eventually relapse. However, we hope that there soon will be some patients who do not relapse.

What are the typical pathologic manifestations of this cancer? Does it affect everyone equally, or in specific ways in each person?

In multiple myeloma, we often say there are multiple myelomas. Clinically, the disease presents in most patients, around 80%, with two clinical manifestations: anemia and bone lesions. Less frequently, patients may also have kidney failure, hypercalcemia, and a higher tendency toward infection. Behind this rather common symptomatology, from a molecular and genetic perspective, each myeloma is practically unique, adding complexity to its treatment. Therefore, ultimately, myelomas end up being refractory.

Elranatamab is a new therapeutic tool. For which patients is it recommended?

It is a bispecific monoclonal antibody that corresponds to the new monotherapy strategies we have for treating patients with multiple myeloma. On the one hand, it targets damaged plasma cells, which are the patient’s tumor cells, and on the other, it binds the patient’s T cells and redirects them to the tumor niche. When this happens, the T cell activates and destroys the tumor cell.

This medication has been approved for patients with relapsed myeloma who have received traditional drugs for their treatment. We know well that patients who have already received proteasome inhibitors, immunomodulators, and anti-CD38 antibodies typically need something new after treatment. Before, there were no other options, and we would reuse what had been previously used. Now we have elranatamab, a bispecific monoclonal antibody targeting a new receptor that has shown significant responses as monotherapy.

More than 60% of patients respond, and more than 30% achieve complete remission. The key is the response duration and progression-free survival of almost a year and a half. This is the longest progression-free survival we have seen to date in previous lines. Therefore, it fills the needs we had for these relapsed or refractory myeloma patients.
 

What advantages does this new treatment offer?

It represents a therapeutic innovation because, as mentioned, it achieves a response in more than 60% of patients, and around 35% achieve complete remission. The median response duration has not been reached yet. Progression-free survival is 17.2 months, almost a year and a half, and overall survival is almost two years. 

Furthermore, it is administered as subcutaneous monotherapy weekly for the first six cycles and then every 15 days. It has a good safety profile, although some adverse events are known, so we have strategies to combat or mitigate them, making the treatment generally well tolerated.
 

What side effects are being observed?

They are manageable. When the drug is first administered, patients may experience what we call a cytokine release syndrome, which is a result of the treatment’s mechanism. However, we can predict very well when it occurs, usually 2 days after the first doses, and we have strategies to mitigate it.

The second most common adverse event we need to be cautious about is infection. Nowadays, before starting treatment, patients update their vaccination schedule, receive antiviral prophylaxis, and receive prophylaxis against certain germs, resulting in reduced infections. However, infections are probably the adverse events we need to be most careful about when treating the patient.

We must ensure that prophylaxis is performed, and if fever occurs and an infection is suspected, cultures and all kinds of studies must be done to identify and treat it properly.
 

How does elranatamab change the treatment of an incurable disease? Does it bring us closer to a cure or to making multiple myeloma a manageable chronic disease?

With the already approved elranatamab, the most important aspect is that it adds another treatment option for patients with myeloma. With the progression-free survival data I indicated, life expectancy is increased, with a good quality of life and acceptable safety.

Obviously, elranatamab is still under study and development, even in early lines, including in patients with newly diagnosed myeloma. When we are choosing first-line therapy, we select the best patients by combining traditional drugs with these new immunotherapies, such as elranatamab, it is likely that we are much closer to offering a cure to specific subgroups.

Although it won’t happen in all cases, I believe it will be applicable to a significant subgroup of patients, making chronicity of the disease a reality we are already approaching. Each day, we encounter more patients receiving different lines of treatment and ultimately meeting their life expectancy with myeloma. Even though some may die, it is often due to causes not related to myeloma. This is the most important contribution of these innovations, such as elranatamab.

“Therapeutic innovations like elranatamab achieve a lasting response in 61% of patients with multiple myeloma and complete remission in 30%,” said María Victoria Mateos, MD, PhD, a consultant physician in the Hematology Service at the University Clinical Hospital of Salamanca, Spain, and president of the Spanish Society of Haematology and Haemotherapy.

“The introduction of treatments such as elranatamab (Elrexfio) is allowing patients with multiple myeloma, which is still incurable for now, to have different options and achieve long periods of remission, thus improving their survival,” she added. “This therapeutic innovation is highly effective and well tolerated in patients with relapse or refractory multiple myeloma.” The overall response rate is “up to 61%, early, deep, and long-lasting.”

In an interview with El Médico Interactivo, Dr. Mateos explained the new approaches to multiple myeloma. She highlighted the effectiveness of new treatments and reviewed the latest data on this disease, which were presented at the recent European Hematology Association Congress.
 

What is the incidence rate of multiple myeloma in the Spanish population?

Multiple myeloma has an incidence of approximately 4-5 new cases per 100,000 inhabitants per year. This means that around 3000 new cases are diagnosed each year in Spain. As with most tumors, multiple myeloma is generally slightly more common in males than females. It is the third most frequent hematologic cancer in men (1757 new cases) and women (1325 new cases), behind lymphoma and leukemias.

At what age is it most often diagnosed?

It affects older people, with recent reports indicating around 68-69 years as the median age. Although more young people are being diagnosed with multiple myeloma, analyses of how this hematologic cancer affects the general population show that it generally impacts patients over age 65 years.

What is the typical survival prognosis?

Thanks to research and therapeutic innovation, the prognosis has changed significantly over the past 20-25 years. Today, if a patient with multiple myeloma receives a diagnosis and does not exhibit poor prognostic characteristics (and this description fits approximately 70%-80% of patients with multiple myeloma), it is realistic to expect a survival exceeding 10 years. A few years ago, this outcome was unimaginable, but a significant amount of therapeutic innovation has made it possible. That’s why I emphasize that it is realistic to provide these data with such a positive outlook.

Is multiple myeloma a refractory type of cancer?

It was a refractory type of cancer. Twenty years ago, there were no treatment options, and therefore survival was around 2-3 years, because treatment mainly consisted of using alkylating agents and corticosteroids. This is what made it refractory.

With the emergence of new therapeutic innovations, patients have been responding better and their responses are lasting longer. Although there is still a group of patients, about 10%-15%, with a poor prognosis and refractory disease, those with standard risk are responding better to different therapies.

Although most patients will eventually exhaust the treatments, which until now were primarily triple-drug regimens (such as proteasome inhibitors, immunomodulators, and antiCD38 antibodies), the introduction of new therapies is extending the duration of responses.
 

Is the risk for relapse high?

It is very high, in the sense that almost all patients with multiple myeloma eventually relapse. However, we hope that there soon will be some patients who do not relapse.

What are the typical pathologic manifestations of this cancer? Does it affect everyone equally, or in specific ways in each person?

In multiple myeloma, we often say there are multiple myelomas. Clinically, the disease presents in most patients, around 80%, with two clinical manifestations: anemia and bone lesions. Less frequently, patients may also have kidney failure, hypercalcemia, and a higher tendency toward infection. Behind this rather common symptomatology, from a molecular and genetic perspective, each myeloma is practically unique, adding complexity to its treatment. Therefore, ultimately, myelomas end up being refractory.

Elranatamab is a new therapeutic tool. For which patients is it recommended?

It is a bispecific monoclonal antibody that corresponds to the new monotherapy strategies we have for treating patients with multiple myeloma. On the one hand, it targets damaged plasma cells, which are the patient’s tumor cells, and on the other, it binds the patient’s T cells and redirects them to the tumor niche. When this happens, the T cell activates and destroys the tumor cell.

This medication has been approved for patients with relapsed myeloma who have received traditional drugs for their treatment. We know well that patients who have already received proteasome inhibitors, immunomodulators, and anti-CD38 antibodies typically need something new after treatment. Before, there were no other options, and we would reuse what had been previously used. Now we have elranatamab, a bispecific monoclonal antibody targeting a new receptor that has shown significant responses as monotherapy.

More than 60% of patients respond, and more than 30% achieve complete remission. The key is the response duration and progression-free survival of almost a year and a half.

Childhood cancers represent a diverse group of neoplasms, and thanks to advances in treatment, survival rates have improved significantly. Today, more than 80%-85% of children diagnosed with cancer in developed countries survive into adulthood.

This increase in survival has brought new challenges, however. Compared with the general population, childhood cancer survivors (CCS) are at a notably higher risk for early mortality, developing secondary cancers, and experiencing various long-term clinical and psychosocial issues stemming from their disease or its treatment.

Long-term follow-up care for CCS is a complex and evolving field. Despite ongoing efforts to establish global and national guidelines, current evidence indicates that the care and management of these patients remain suboptimal.

Sexual dysfunction is a common and significant late effect among CCS. The disruptions caused by cancer and its treatment can interfere with normal physiological and psychological development, leading to issues with sexual function. This aspect of health is critical as it influences not just physical well-being but also psychosocial, developmental, and emotional health.
 

Characteristics and Mechanisms

Sexual functioning encompasses the physiological and psychological aspects of sexual behavior, including desire, arousal, orgasm, sexual pleasure, and overall satisfaction.

As CCS reach adolescence or adulthood, they often face sexual and reproductive issues, particularly as they enter romantic relationships.

Sexual functioning is a complex process that relies on the interaction of various factors, including physiological health, psychosexual development, romantic relationships, body image, and desire.

Despite its importance, the impact of childhood cancer on sexual function is often overlooked, even though cancer and its treatments can have lifelong effects. 
 

Sexual Function in CCS

A recent review aimed to summarize the existing research on sexual function among CCS, highlighting assessment tools, key stages of psychosexual development, common sexual problems, and the prevalence of sexual dysfunction.

The review study included 22 studies published between 2000 and 2022, comprising two qualitative, six cohort, and 14 cross-sectional studies.

Most CCS reached all key stages of psychosexual development at an average age of 29.8 years. Although some milestones were achieved later than is typical, many survivors felt they reached these stages at the appropriate time. Sexual initiation was less common among those who had undergone intensive neurotoxic treatments, such as those diagnosed with brain tumors or leukemia in childhood.

In a cross-sectional study of CCS aged 17-39 years, about one third had never engaged in sexual intercourse, 41.4% reported never experiencing sexual attraction, 44.8% were dissatisfied with their sex lives, and many rarely felt sexually attractive to others. Another study found that common issues among CCS included a lack of interest in sex (30%), difficulty enjoying sex (24%), and difficulty becoming aroused (23%). However, comparing and analyzing these problems was challenging due to the lack of standardized assessment criteria.

The prevalence of sexual dysfunction among CCS ranged from 12.3% to 46.5%. For males, the prevalence ranged from 12.3% to 54.0%, while for females, it ranged from 19.9% to 57.0%.
 

Factors Influencing Sexual Function

The review identified the following four categories of factors influencing sexual function in CCS: Demographic, treatment-related, psychological, and physiological.

Demographic factors: Gender, age, education level, relationship status, income level, and race all play roles in sexual function.

Female survivors reported more severe sexual dysfunction and poorer sexual health than did male survivors. Age at cancer diagnosis, age at evaluation, and the time since diagnosis were closely linked to sexual experiences. Patients diagnosed with cancer during childhood tended to report better sexual function than those diagnosed during adolescence.

Treatment-related factors: The type of cancer and intensity of treatment, along with surgical history, were significant factors. Surgeries involving the spinal cord or sympathetic nerves, as well as a history of prostate or pelvic surgery, were strongly associated with erectile dysfunction in men. In women, pelvic surgeries and treatments to the pelvic area were commonly linked to sexual dysfunction.

The association between treatment intensity and sexual function was noted across several studies, although the results were not always consistent. For example, testicular radiation above 10 Gy was positively correlated with sexual dysfunction. Women who underwent more intensive treatments were more likely to report issues in multiple areas of sexual function, while men in this group were less likely to have children.

Among female CCS, certain types of cancer, such as germ cell tumors, renal tumors, and leukemia, present a higher risk for sexual dysfunction. Women who had CNS tumors in childhood frequently reported problems like difficulty in sexual arousal, low sexual satisfaction, infrequent sexual activity, and fewer sexual partners, compared with survivors of other cancers. Survivors of acute lymphoblastic leukemia and those who underwent hematopoietic stem cell transplantation (HSCT) also showed varying degrees of impaired sexual function, compared with the general population. The HSCT group showed significant testicular damage, including reduced testicular volumes, low testosterone levels, and low sperm counts.

Psychological factors: These factors, such as emotional distress, play a significant role in sexual dysfunction among CCS. Symptoms like anxiety, nervousness during sexual activity, and depression are commonly reported by those with sexual dysfunction. The connection between body image and sexual function is complex. Many CCS with sexual dysfunction express concern about how others, particularly their partners, perceived their altered body image due to cancer and its treatment.

Physiological factors: In male CCS, low serum testosterone levels and low lean muscle mass are linked to an increased risk for sexual dysfunction. Treatments involving alkylating agents or testicular radiation, and surgery or radiotherapy targeting the genitourinary organs or the hypothalamic-pituitary region, can lead to various physiological and endocrine disorders, contributing to sexual dysfunction. Despite these risks, there is a lack of research evaluating sexual function through the lens of the hypothalamic-pituitary-gonadal axis and neuroendocrine pathways.

The association between treatment intensity and sexual function was noted across several studies, although the results were not always consistent. For example, testicular radiation above 10 Gy was positively correlated with sexual dysfunction. Women who underwent more intensive treatments were more likely to report issues in multiple areas of sexual function, while men in this group were less likely to have children.

Among female CCS, certain types of cancer, such as germ cell tumors, renal tumors, and leukemia, present a higher risk for sexual dysfunction. Women who had CNS tumors in childhood frequently reported problems like difficulty in sexual arousal, low sexual satisfaction, infrequent sexual activity, and fewer sexual partners, compared with survivors of other cancers. Survivors of acute lymphoblastic leukemia and those who underwent hematopoietic stem cell transplantation (HSCT) also showed varying degrees of impaired sexual function, compared with the general population. The HSCT group showed significant testicular damage, including reduced testicular volumes, low testosterone levels, and low sperm counts.

Psychological factors: These factors, such as emotional distress, play a significant role in sexual dysfunction among CCS. Symptoms like anxiety, nervousness during sexual activity, and depression are commonly reported by those with sexual dysfunction. The connection between body image and sexual function is complex. Many CCS with sexual dysfunction express concern about how others, particularly their partners, perceived their altered body image due to cancer and its treatment.

Physiological factors: In male CCS, low serum testosterone levels and low lean muscle mass are linked to an increased risk for sexual dysfunction. Treatments involving alkylating agents or testicular radiation, and surgery or radiotherapy targeting the genitourinary organs or the hypothalamic-pituitary region, can lead to various physiological and endocrine disorders, contributing to sexual dysfunction. Despite these risks, there is a lack of research evaluating sexual function through the lens of the hypothalamic-pituitary-gonadal axis and neuroendocrine pathways.

The US Food and Drug Administration (FDA) has declined to approve linvoseltamab (Regeneron), a bispecific antibody being evaluated to treat relapsed/refractory multiple myeloma after progression on at least three previous therapies.

On August 20, Regeneron announced that it had received a complete response letter from the FDA regarding its Biologics License Application for linvoseltamab, citing issues at a third-party manufacturer.

More specifically, Regeneron said in a company press release that the FDA issued the complete response letter based on findings from “a preapproval inspection at a third-party fill/finish manufacturer for another company’s product candidate.”

The third-party manufacturer told Regeneron it believes that the issues have been resolved, Regeneron said, and that facility is now awaiting a follow-up FDA inspection in the “coming months.”

Regeneron noted that this “anticipated outcome” from the FDA preapproval inspection had been disclosed previously during a company earnings call on August 1.

On that call, Regeneron had discussed the FDA’s concerns about the third-party manufacturer and anticipated that “any potential FDA approval for linvoseltamab is likely to be delayed beyond the August 22 PDUFA date.”

Regeneron had initially filed a Biologics License Application for its bispecific antibody in 2023, based on findings from the phase 1/2 single arm LINKER-MM1 trial. 

In the latest published trial findings, investigators reported that, at a median follow-up of about 14 months, 71% of the 117 patients receiving 200 mg of linvoseltamab achieved an overall response, with 50% achieving a complete response. The probability of survival at 12 months was 75.3%.

This would have been the first approval for linvoseltamab, which would have joined two agents already on the US market for relapsed/refractory multiple myeloma: teclistamab (Tecvayli, Janssen) and elranatamab (Elrexfio, Pfizer).

Pricing information for linvoseltamab is not yet available, but its competitors teclistamab and elranatamab are reported to cost around $40,000 per month.

The US Food and Drug Administration (FDA) has approved axatilimab (Niktimvo, Incyte Corporation and Syndax) for the treatment of adult and pediatric patients with chronic graft versus host disease (GVHD) who have not responded to at least two prior lines of systemic therapy and who weigh ≥ 40 kg.

Chronic GVHD is a potentially life-threatening complication of allogeneic hematopoietic stem cell transplantation that develops in about 50% of transplant recipients.

The first-in-class treatment for chronic GVHD is a monoclonal antibody that targets the colony-stimulating factor 1 (CSF-1) receptor. Approval for axatilimab followed priority review of Incyte’s Biologic License Application and was based on findings from the open-label phase 2 AGAVE-201 trial. 

Study participants had chronic GVHD after allogeneic hematopoietic stem cell transplantation and had failed to respond to at least two prior lines of systemic therapy (median, four lines of therapy). Prior therapies included ruxolitinib, belumosudil, and ibrutinib in 74%, 23%, and 31% of patients, respectively. Overall, 239 patients were enrolled at 121 study sites and were randomly assigned 1:1:1 to three doses.

The FDA recommended dose of axatilimab is 0.3 mg/kg (to a maximum of 35 mg) as an intravenous infusion over 30 minutes every 2 weeks until disease progression or unacceptable toxicity. Other doses tested in the AGAVE-201 trial were 1 mg/kg every 2 weeks and 3 mg/kg every 4 weeks. 

The trial measured overall response rate over the first six cycles (24 weeks). In the 79 patients who received the recommended 0.3-mg/kg dose, the overall response rate was 75%, and the median time to first response was 1.5 months (range, 0.9-5.1). The median duration of response — measured from first response to progression, death, or switch to a new systemic therapy for chronic GVHD — was 1.9 months. 

In those who responded to the therapy, there were no deaths or new therapies required in 60% of patients.

The most common adverse reactions, occurring in 15% or more patients, included increased aspartate aminotransferase, infection (pathogen unspecified), increased alanine aminotransferase, decreased phosphate, decreased hemoglobin, musculoskeletal pain, increased lipase, fatigue, increased amylase, increased calcium, increased creatine phosphokinase, nausea, headache, diarrhea, cough, pyrexia, and dyspnea. 

In the AGAVE-201 trial results, researchers noted that drug discontinuation from treatment-emergent adverse events occurred in 6% of patients in the 0.3-mg/kg cohort, in 22% in the 1-mg/kg cohort, and in 18% in the 3-mg/kg cohort. Fatal treatment-emergent adverse events occurred in 1.3% of patients in the 0.3-mg/kg cohort. 

“Advanced chronic GVHD is characterized by the development of fibrotic tissue across multiple organ systems, including most commonly the skin and mucosa, and can be extremely difficult to treat, leading to high rates of morbidity and mortality,” lead study author Daniel Wolff, MD, PhD, head of the GVHD Center at the University Hospital Regensburg, Germany, said in a company press release. “I am excited that Niktimvo is designed to specifically target key drivers of inflammation and fibrosis in chronic GVHD, and I am highly encouraged by the robust responses observed across all organs and patient subgroups within the heavily pretreated population enrolled in the AGAVE-201 trial. I look forward to having a new and differentiated treatment option for my patients who need additional therapies to address this very difficult to manage, debilitating, disease.”

Chemotherapy has fallen out of favor for treating cancer toward the end of life. The toxicity is too high, and the benefit, if any, is often too low.

Immunotherapy, however, has been taking its place. Checkpoint inhibitors are increasingly being initiated to treat metastatic cancer in patients approaching the end of life and have become the leading driver of end-of-life cancer spending.

This means “there are patients who are getting immunotherapy who shouldn’t,” said Yale University, New Haven, Connecticut, surgical oncologist Sajid Khan, MD, senior investigator on a recent study that highlighted the growing use of these agents in patients’ last month of life.

What’s driving this trend, and how can oncologists avoid overtreatment with immunotherapy at the end of life?
 

The N-of-1 Patient

With immunotherapy at the end of life, “each of us has had our N-of-1” where a patient bounces back with a remarkable and durable response, said Don Dizon, MD, a gynecologic oncologist at Brown University, Providence, Rhode Island.

He recalled a patient with sarcoma who did not respond to chemotherapy. But after Dr. Dizon started her on immunotherapy, everything turned around. She has now been in remission for 8 years and counting.

The possibility of an unexpected or remarkable responder is seductive. And the improved safety of immunotherapy over chemotherapy adds to the allure.

Meanwhile, patients are often desperate. It’s rare for someone to be ready to stop treatment, Dr. Dizon said. Everybody “hopes that they’re going to be the exceptional responder.”

At the end of the day, the question often becomes: “Why not try immunotherapy? What’s there to lose?”

This thinking may be prompting broader use of immunotherapy in late-stage disease, even in instances with no Food and Drug Administration indication and virtually no supportive data, such as for metastatic ovarian cancer, Dr. Dizon said.
 

Back to Earth

The problem with the hopeful approach is that end-of-life turnarounds with immunotherapy are rare, and there’s no way at the moment to predict who will have one, said Laura Petrillo, MD, a palliative care physician at Massachusetts General Hospital, Boston.

Even though immunotherapy generally comes with fewer adverse events than chemotherapy, catastrophic side effects are still possible.

Dr. Petrillo recalled a 95-year-old woman with metastatic cancer who was largely asymptomatic.

She had a qualifying mutation for a checkpoint inhibitor, so her oncologist started her on one. The patient never bounced back from the severe colitis the agent caused, and she died of complications in the hospital.

Although such reactions with immunotherapy are uncommon, less serious problems caused by the agents can still have a major impact on a person’s quality of life. Low-grade diarrhea, for instance, may not sound too bad, but in a patient’s daily life, it can translate to six or more episodes a day.

Even with no side effects, prescribing immunotherapy can mean that patients with limited time left spend a good portion of it at an infusion clinic instead of at home. These patients are also less likely to be referred to hospice and more likely to be admitted to and die in the hospital.

And with treatments that can cost $20,000 per dose, financial toxicity becomes a big concern.

In short, some of the reasons why chemotherapy is not recommended at the end of life also apply to immunotherapy, Dr. Petrillo said.
 

Prescribing Decisions

Recent research highlights the growing use of immunotherapy at the end of life.

Dr. Khan’s retrospective study found, for instance, that the percentage of patients starting immunotherapy in the last 30 days of life increased by about fourfold to fivefold over the study period for the three cancers analyzed — stage IV melanoma, lung, and kidney cancers.

Among the population that died within 30 days, the percentage receiving immunotherapy increased over the study periods — 0.8%-4.3% for melanoma, 0.9%-3.2% for NSCLC, and 0.5%-2.6% for kidney cell carcinoma — prompting the conclusion that immunotherapy prescriptions in the last month of life are on the rise.

Prescribing immunotherapy in patients who ultimately died within 1 month occurred more frequently at low-volume, nonacademic centers than at academic or high-volume centers, and outcomes varied by practice setting.

Patients had better survival outcomes overall when receiving immunotherapy at academic or high-volume centers — a finding Dr. Khan said is worth investigating further. Possible explanations include better management of severe immune-related side effects at larger centers and more caution when prescribing immunotherapy to “borderline” candidates, such as those with several comorbidities.

Importantly, given the retrospective design, Dr. Khan and colleagues already knew which patients prescribed immunotherapy died within 30 days of initiating treatment.

More specifically, 5192 of 71,204 patients who received immunotherapy (7.3%) died within a month of initiating therapy, while 66,012 (92.7%) lived beyond that point.

The study, however, did not assess how the remaining 92.7% who lived beyond 30 days fared on immunotherapy and the differences between those who lived less than 30 days and those who survived longer.

Knowing the outcome of patients at the outset of the analysis still leaves open the question of when immunotherapy can extend life and when it can’t for the patient in front of you.

To avoid overtreating at the end of life, it’s important to have “the same standard that you have for giving chemotherapy. You have to treat it with the same respect,” said Moshe Chasky, MD, a community medical oncologist with Alliance Cancer Specialists in Philadelphia, Pennsylvania. “You can’t just be throwing” immunotherapy around “at the end of life.”

While there are no clear predictors of risk and benefit, there are some factors to help guide decisions.

As with chemotherapy, Dr. Petrillo said performance status is key. Dr. Petrillo and colleagues found that median overall survival with immune checkpoint inhibitors for advanced non–small cell lung cancer was 14.3 months in patients with an Eastern Cooperative Oncology Group performance score of 0-1 but only 4.5 months with scores of ≥ 2.

Dr. Khan also found that immunotherapy survival is, unsurprisingly, worse in patients with high metastatic burdens and more comorbidities.

“You should still consider immunotherapy for metastatic melanoma, non–small cell lung cancer, and renal cell carcinoma,” Dr. Khan said. The message here is to “think twice before using” it, especially in comorbid patients with widespread metastases.

“Just because something can be done doesn’t always mean it should be done,” he said.

At Yale, when Dr. Khan works, immunotherapy decisions are considered by a multidisciplinary tumor board. At Mass General, immunotherapy has generally moved to the frontline setting, and the hospital no longer prescribes checkpoint inhibitors to hospitalized patients because the cost is too high relative to the potential benefit, Dr. Petrillo explained.

Still, with all the uncertainties about risk and benefit, counseling patients is a challenge. Dr. Dizon called it “the epitome of shared decision-making.”

Dr. Petrillo noted that it’s critical not to counsel patients based solely on the anecdotal patients who do surprisingly well.

“It’s hard to mention that and not have that be what somebody anchors on,” she said. But that speaks to “how desperate people can feel, how hopeful they can be.”

Dr. Khan, Dr. Petrillo, and Dr. Chasky all reported no relevant conflicts of interest.

Immunotherapy, however, has been taking its place. Checkpoint inhibitors are increasingly being initiated to treat metastatic cancer in patients approaching the end of life and have become the leading driver of end-of-life cancer spending.

This means “there are patients who are getting immunotherapy who shouldn’t,” said Yale University, New Haven, Connecticut, surgical oncologist Sajid Khan, MD, senior investigator on a recent study that highlighted the growing use of these agents in patients’ last month of life.

What’s driving this trend, and how can oncologists avoid overtreatment with immunotherapy at the end of life?
 

The N-of-1 Patient

With immunotherapy at the end of life, “each of us has had our N-of-1” where a patient bounces back with a remarkable and durable response, said Don Dizon, MD, a gynecologic oncologist at Brown University, Providence, Rhode Island.

He recalled a patient with sarcoma who did not respond to chemotherapy. But after Dr. Dizon started her on immunotherapy, everything turned around. She has now been in remission for 8 years and counting.

The possibility of an unexpected or remarkable responder is seductive. And the improved safety of immunotherapy over chemotherapy adds to the allure.

Meanwhile, patients are often desperate. It’s rare for someone to be ready to stop treatment, Dr. Dizon said. Everybody “hopes that they’re going to be the exceptional responder.”

At the end of the day, the question often becomes: “Why not try immunotherapy? What’s there to lose?”

This thinking may be prompting broader use of immunotherapy in late-stage disease, even in instances with no Food and Drug Administration indication and virtually no supportive data, such as for metastatic ovarian cancer, Dr. Dizon said.
 

Back to Earth

The problem with the hopeful approach is that end-of-life turnarounds with immunotherapy are rare, and there’s no way at the moment to predict who will have one, said Laura Petrillo, MD, a palliative care physician at Massachusetts General Hospital, Boston.

Even though immunotherapy generally comes with fewer adverse events than chemotherapy, catastrophic side effects are still possible.

Dr. Petrillo recalled a 95-year-old woman with metastatic cancer who was largely asymptomatic.

She had a qualifying mutation for a checkpoint inhibitor, so her oncologist started her on one. The patient never bounced back from the severe colitis the agent caused, and she died of complications in the hospital.

Although such reactions with immunotherapy are uncommon, less serious problems caused by the agents can still have a major impact on a person’s quality of life. Low-grade diarrhea, for instance, may not sound too bad, but in a patient’s daily life, it can translate to six or more episodes a day.

Even with no side effects, prescribing immunotherapy can mean that patients with limited time left spend a good portion of it at an infusion clinic instead of at home. These patients are also less likely to be referred to hospice and more likely to be admitted to and die in the hospital.

And with treatments that can cost $20,000 per dose, financial toxicity becomes a big concern.

In short, some of the reasons why chemotherapy is not recommended at the end of life also apply to immunotherapy, Dr. Petrillo said.
 

Prescribing Decisions

Recent research highlights the growing use of immunotherapy at the end of life.

Dr. Khan’s retrospective study found, for instance, that the percentage of patients starting immunotherapy in the last 30 days of life increased by about fourfold to fivefold over the study period for the three cancers analyzed — stage IV melanoma, lung, and kidney cancers.

Among the population that died within 30 days, the percentage receiving immunotherapy increased over the study periods — 0.8%-4.3% for melanoma, 0.9%-3.2% for NSCLC, and 0.5%-2.6% for kidney cell carcinoma — prompting the conclusion that immunotherapy prescriptions in the last month of life are on the rise.

Prescribing immunotherapy in patients who ultimately died within 1 month occurred more frequently at low-volume, nonacademic centers than at academic or high-volume centers, and outcomes varied by practice setting.

Patients had better survival outcomes overall when receiving immunotherapy at academic or high-volume centers — a finding Dr. Khan said is worth investigating further. Possible explanations include better management of severe immune-related side effects at larger centers and more caution when prescribing immunotherapy to “borderline” candidates, such as those with several comorbidities.

Importantly, given the retrospective design, Dr. Khan and colleagues already knew which patients prescribed immunotherapy died within 30 days of initiating treatment.

More specifically, 5192 of 71,204 patients who received immunotherapy (7.3%) died within a month of initiating therapy, while 66,012 (92.7%) lived beyond that point.

The study, however, did not assess how the remaining 92.7% who lived beyond 30 days fared on immunotherapy and the differences between those who lived less than 30 days and those who survived longer.

Knowing the outcome of patients at the outset of the analysis still leaves open the question of when immunotherapy can extend life and when it can’t for the patient in front of you.

To avoid overtreating at the end of life, it’s important to have “the same standard that you have for giving chemotherapy. You have to treat it with the same respect,” said Moshe Chasky, MD, a community medical oncologist with Alliance Cancer Specialists in Philadelphia, Pennsylvania. “You can’t just be throwing” immunotherapy around “at the end of life.”

While there are no clear predictors of risk and benefit, there are some factors to help guide decisions.

As with chemotherapy, Dr. Petrillo said performance status is key. Dr. Petrillo and colleagues found that median overall survival with immune checkpoint inhibitors for advanced non–small cell lung cancer was 14.3 months in patients with an Eastern Cooperative Oncology Group performance score of 0-1 but only 4.5 months with scores of ≥ 2.

Dr. Khan also found that immunotherapy survival is, unsurprisingly, worse in patients with high metastatic burdens and more comorbidities.

“You should still consider immunotherapy for metastatic melanoma, non–small cell lung cancer, and renal cell carcinoma,” Dr. Khan said. The message here is to “think twice before using” it, especially in comorbid patients with widespread metastases.

“Just because something can be done doesn’t always mean it should be done,” he said.

At Yale, when Dr. Khan works, immunotherapy decisions are considered by a multidisciplinary tumor board. At Mass General, immunotherapy has generally moved to the frontline setting, and the hospital no longer prescribes checkpoint inhibitors to hospitalized patients because the cost is too high relative to the potential benefit, Dr. Petrillo explained.

Still, with all the uncertainties about risk and benefit, counseling patients is a challenge. Dr. Dizon called it “the epitome of shared decision-making.”

Dr. Petrillo noted that it’s critical not to counsel patients based solely on the anecdotal patients who do surprisingly well.

“It’s hard to mention that and not have that be what somebody anchors on,” she said. But that speaks to “how desperate people can feel, how hopeful they can be.”

Dr. Khan, Dr. Petrillo, and Dr. Chasky all reported no relevant conflicts of interest.
