Imagine a patient suffering with horrible psoriasis for decades having failed “every available treatment.” Imagine him living all that time with “flaking, cracking, painful, itchy skin,” only to develop cirrhosis after exposure to toxic therapies.

Then imagine the experience for that patient when, 2 weeks after initiating treatment with a new interleukin-17 inhibitor, his skin clears completely.

“Two weeks later it’s all gone – it was a moment to behold,” said Joel M. Gelfand, MD, professor of dermatology and epidemiology at the University of Pennsylvania, Philadelphia, who had cared for the man for many years before a psoriasis treatment revolution of sorts took the field of dermatology by storm.

“The progress has been breathtaking – there’s no other way to describe it – and it feels like a miracle every time I see a new patient who has tough disease and I have all these things to offer them,” he continued. “For most patients, I can really help them and make a major difference in their life.”

Much of the progress in psoriasis treatment in the past 50 years unfolded over the past 2 decades, with biologics emerging for psoriasis, said Mark Lebwohl, MD, Waldman professor of dermatology and chair of the Kimberly and Eric J. Waldman department of dermatology at the Icahn School of Medicine at Mount Sinai, New York.

Dr. Lebwohl recounted some of his own experiences with psoriasis patients before the advent of treatments – particularly biologics – that have transformed practice.

There was a time when psoriasis patients had little more to turn to than the effective – but “disgusting” – Goeckerman Regimen involving cycles of UVB light exposure and topical crude coal tar application. Initially, the regimen, which was introduced in the 1920s, was used around the clock on an inpatient basis until the skin cleared, Dr. Lebwohl said.

In the 1970s, the immunosuppressive chemotherapy drug methotrexate became the first oral systemic therapy approved for severe psoriasis. For those with disabling disease, it offered some hope for relief, but only about 40% of patients achieved at least a 75% reduction in the Psoriasis Area and Severity Index score (PASI 75), he said, adding that they did so at the expense of the liver and bone marrow. “But it was the only thing we had for severe psoriasis other than light treatments.”

In the 1980s and 1990s, oral retinoids emerged as a treatment for psoriasis, and the immunosuppressive drug cyclosporine used to prevent organ rejection in some transplant patients was found to clear psoriasis in affected transplant recipients. Although they brought relief to some patients with severe, disabling disease, these also came with a high price. “It’s not that effective, and it has lots of side effects ... and causes kidney damage in essentially 100% of patients,” Dr. Lebwohl said of cyclosporine.

“So we had treatments that worked, but because the side effects were sufficiently severe, a lot of patients were not treated,” he said.

Enter the biologics era

The early 2000s brought the first two approvals for psoriasis: alefacept (Amevive), a “modestly effective, but quite safe” immunosuppressive dimeric fusion protein approved in early 2003 for moderate to severe plaque psoriasis, and efalizumab (Raptiva), a recombinant humanized monoclonal antibody approved in October 2003; both were T-cell–targeted therapies. The former was withdrawn from the market voluntarily as newer agents became available, and the latter was withdrawn in 2009 because of a link with development of progressive multifocal leukoencephalopathy.

Tumor necrosis factor (TNF) blockers, which had been used effectively for RA and Crohn’s disease, emerged next, and were highly effective, much safer than the systemic treatments, and gained “very widespread use,” Dr. Lebwohl said.

Alan Menter, MD, chairman of the division of dermatology at Baylor University Medical Center, Dallas, also a prolific researcher – and chair of the guidelines committee that published two new sets of guidelines for psoriasis treatment in 2019 – said that the field of dermatology was “late to the biologic evolution,” as many of the early biologics were first approved for PsA.

“But over the last 10 years, things have changed dramatically,” he said. “After that we suddenly leapt ahead of everybody. ... We now have 11 biologic drugs approved for psoriasis, which is more than any other disease has available.”

It’s been “highly exciting” to see this “evolution and revolution,” he commented, adding that one of the next challenges is to address the comorbidities, such as cardiovascular disease, associated with psoriasis.

“The big question now ... is if you improve skin and you improve joints, can you potentially reduce the risk of coronary artery disease,” he said. “Everybody is looking at that, and to me it’s one of the most exciting things that we’re doing.”

Work is ongoing to look at whether the IL-17s and IL-23s have “other indications outside of the skin and joints,” both within and outside of dermatology.

Like Dr. Gottlieb, Dr. Menter also mentioned the potential for hidradenitis suppurativa, and also for a condition that is rarely discussed or studied: genital psoriasis. Ixekizumab has recently been shown to work in about 75% of patients with genital psoriasis, he noted.

Another important area of research is the identification of biomarkers for predicting response and relapse, he said. For now, biomarker research has disappointed, he added, predicting that it will take at least 3-5 years before biomarkers to help guide treatment are identified.

Indeed, Dr. Gelfand, who also is director of the Psoriasis and Phototherapy Treatment Center, vice chair of clinical research, and medical director of the dermatology clinical studies unit at the University of Pennsylvania, agreed there is a need for research to improve treatment selection.

Advances are being made in genetics – with more than 80 different genes now identified as being related to psoriasis – and in medical informatics – which allow thousands of patients to be followed for years, he said, noting that this could elucidate immunopathological features that can improve treatments, predict and prevent comorbidity, and further improve outcomes.

“We also need care that is more patient centered,” he said, describing the ongoing pragmatic LITE trial of home- or office-based phototherapy for which he is the lead investigator, and other studies that he hopes will expand access to care.

Kenneth Brian Gordon, MD, chair and professor of dermatology at the Medical College of Wisconsin, Milwaukee, whose career started in the basic science immunology arena, added the need for expanding benefit to patients with more-moderate disease. Like Dr. Menter, he identified psoriasis as the area in medicine that has had the greatest degree of advancement, except perhaps for hepatitis C.

He described the process not as a “bench-to-bedside” story, but as a bedside-to-bench, then “back-to-bedside” story.

It was really about taking those early T-cell–targeted biologics and anti-TNF agents from bedside to bench with the realization of the importance of the IL-23 and IL-17 pathways, and that understanding led back to the bedside with the development of the newest agents – and to a “huge difference in patient’s lives.”

“But we’ve gotten so good at treating patients with severe disease ... the question now is how to take care of those with more-moderate disease,” he said, noting that a focus on cost and better delivery systems will be needed for that population.

That research is underway, and the future looks bright – and clear.
 

“I think with psoriasis therapy and where we’ve come in the last 20 years ... we have a hard time remembering what it was like before we had biologic agents” he said. “Our perspective has changed a lot, and sometimes we forget that.”

In fact, “psoriasis has sort of dragged dermatology into the world of modern clinical trial science, and we can now apply that to all sorts of other diseases,” he said. “The psoriasis trials were the first really well-done large-scale trials in dermatology, and I think that has given dermatology a real leg up in how we do clinical research and how we do evidence-based medicine.”

All of the doctors interviewed for this story have received funds and/or honoraria from, consulted with, are employed with, or served on the advisory boards of manufacturers of biologics. Dr. Gelfand is a copatent holder of resiquimod for treatment of cutaneous T-cell lymphoma and is deputy editor of the Journal of Investigative Dermatology.

ATLANTA – Psoriasis type and patient age at presentation among patients with psoriatic arthritis predict the timing of arthritis symptom synchronicity, according to findings from the Psoriatic Arthritis Registry of Turkey International Database.

Sharon Worcester/MDedge News

However, in those who develop arthritis symptoms first, age at onset is not predictive of psoriatic arthritis (PsA) symptom synchronicity, Umut Kalyoncu, MD, reported at the annual meeting of the American College of Rheumatology.

Of 1,631 patients from the registry, 1,251 had psoriasis first, 71 had arthritis first, and 309 had synchronous onset, which was defined as the onset of both psoriasis and arthritis symptoms within a 12-month period. The time from skin disease to PsA was 155.6 months, –67.4 months, and 1.8 months, among the groups, respectively, and the mean age at PsA onset was similar, ranging from about 41 to 42 years in those who developed arthritis first, said Dr. Kalyoncu, of the department of rheumatology at Hacettepe University, Ankara, Turkey.

However, the mean age of PsA onset among those who developed psoriasis first was 29.4 years, compared with 46.3 years in those who developed arthritis first.

“So there is a really big difference between psoriasis beginning age,” he said.

PsA types also differed by onset symptoms: Axial involvement was more common with arthritis-first onset at 38.0%, compared with 28.8% for psoriasis first and 27.8% for synchronous onset). Oligoarthritis occurred more often with arthritis-first onset (45.1% vs. 30.7% and 29.4%, respectively), and polyarthritis occurred less often with arthritis-first onset (33.8% vs. 49.4% and 47.6%, respectively), he said.

Psoriasis type also differed among the groups: Pustular skin involvement was more common in arthritis-first patients (18.3% vs. 11.9% and 16.5% of psoriasis-first and synchronous-onset patients), scalp lesions as the initial lesion were more common in psoriasis-first patients (48.3% vs. 35.2% of arthritis-first patients and 39.8% of synchronous-onset patients), and genital involvement was present more often in arthritis-first patients (12.7% vs. 6.2% and 4.9% of psoriasis-first and synchronous-onset patients).

Early-onset (type 1) psoriasis was more common in psoriasis-first patients (74% vs. 28.1% and 51.8% of arthritis-first and synchronous-onset patients), whereas late-onset (type 2) psoriasis was more common in arthritis-first patients (71.9% vs. 26.0% and 48.2% for psoriasis-first and synchronous-onset patients).

A family history of psoriasis or PsA was more common in psoriasis-first patients (35.6% vs. 26.3% and 28.2% of arthritis-first and synchronous-onset patients), Dr. Kalyoncu said.

Treatment types did not differ between the groups.

Multiple linear regression analysis for the time elapsed from psoriasis to PsA symptom synchronicity, with all other independent variables set to baseline values, showed an overall intercept interval of 66 months, but with nail involvement, family history, or plaque psoriasis, the interval was extended by 28, 24, and 20 months, respectively. However, the presence of pustular psoriasis decreased the intercept interval by 28 months.

A temporal relationship between the onset of skin psoriasis and PsA is a well-known feature of psoriatic disease, with prior studies showing that the majority of cases involve psoriasis-first onset, Dr. Kalyoncu said, adding that heterogeneity in musculoskeletal and skin involvement is also a known feature.

However, little is known about the role of genetics, he noted.

Therefore, he and his colleagues used the Psoriatic Arthritis Registry of Turkey International Database, which was established in 2014 and now also includes data from patients in Canada and Italy, to explore the associations between disease characteristics and the temporal relationship of skin and musculoskeletal disease.

Based on the findings, age at the onset of psoriasis was the main factor that determined PsA symptom synchronicity, he said.

“We know that HLA-Cw6 is important in genetic susceptibility of psoriatic arthritis, but it is important only for early-onset arthritis, not late-onset psoriasis,” Dr. Kalyoncu said. “So our results make an indirect contribution [to the understanding of] these genetic and immunochemical differences between early-onset and late-onset psoriasis, and we need further future studies about this topic.”

Dr. Kalyoncu reported having no relevant disclosures.

The time from skin disease to PsA was 155.6 months, –67.4 months, and 1.8 months, among the groups, respectively, and the mean age at PsA onset was similar, ranging from about 41 to 42 years in those who developed arthritis first, said Dr. Kalyoncu, of the department of rheumatology at Hacettepe University, Ankara, Turkey.

However, the mean age of PsA onset among those who developed psoriasis first was 29.4 years, compared with 46.3 years in those who developed arthritis first.

“So there is a really big difference between psoriasis beginning age,” he said.

PsA types also differed by onset symptoms: Axial involvement was more common with arthritis-first onset at 38.0%, compared with 28.8% for psoriasis first and 27.8% for synchronous onset). Oligoarthritis occurred more often with arthritis-first onset (45.1% vs. 30.7% and 29.4%, respectively), and polyarthritis occurred less often with arthritis-first onset (33.8% vs. 49.4% and 47.6%, respectively), he said.

Psoriasis type also differed among the groups: Pustular skin involvement was more common in arthritis-first patients (18.3% vs. 11.9% and 16.5% of psoriasis-first and synchronous-onset patients), scalp lesions as the initial lesion were more common in psoriasis-first patients (48.3% vs. 35.2% of arthritis-first patients and 39.8% of synchronous-onset patients), and genital involvement was present more often in arthritis-first patients (12.7% vs. 6.2% and 4.9% of psoriasis-first and synchronous-onset patients).

Early-onset (type 1) psoriasis was more common in psoriasis-first patients (74% vs. 28.1% and 51.8% of arthritis-first and synchronous-onset patients), whereas late-onset (type 2) psoriasis was more common in arthritis-first patients (71.9% vs. 26.0% and 48.2% for psoriasis-first and synchronous-onset patients).

A family history of psoriasis or PsA was more common in psoriasis-first patients (35.6% vs. 26.3% and 28.2% of arthritis-first and synchronous-onset patients), Dr. Kalyoncu said.

Treatment types did not differ between the groups.

Multiple linear regression analysis for the time elapsed from psoriasis to PsA symptom synchronicity, with all other independent variables set to baseline values, showed an overall intercept interval of 66 months, but with nail involvement, family history, or plaque psoriasis, the interval was extended by 28, 24, and 20 months, respectively. However, the presence of pustular psoriasis decreased the intercept interval by 28 months.

A temporal relationship between the onset of skin psoriasis and PsA is a well-known feature of psoriatic disease, with prior studies showing that the majority of cases involve psoriasis-first onset, Dr. Kalyoncu said, adding that heterogeneity in musculoskeletal and skin involvement is also a known feature.

However, little is known about the role of genetics, he noted.

Therefore, he and his colleagues used the Psoriatic Arthritis Registry of Turkey International Database, which was established in 2014 and now also includes data from patients in Canada and Italy, to explore the associations between disease characteristics and the temporal relationship of skin and musculoskeletal disease.

Based on the findings, age at the onset of psoriasis was the main factor that determined PsA symptom synchronicity, he said.

“We know that HLA-Cw6 is important in genetic susceptibility of psoriatic arthritis, but it is important only for early-onset arthritis, not late-onset psoriasis,” Dr. Kalyoncu said. “So our results make an indirect contribution [to the understanding of] these genetic and immunochemical differences between early-onset and late-onset psoriasis, and we need further future studies about this topic.”

Dr. Kalyoncu reported having no relevant disclosures.

ORLANDO – A dasatinib-based two-step treatment regimen before allogeneic hematopoietic cell transplantation (alloHCT) for Philadelphia chromosome–positive acute lymphoblastic leukemia (Ph+ALL) reduces relapse and toxicity and improves survival versus an imatinib-based approach, according to findings from the phase 2 Ph+ALL213 study.

Of 78 evaluable patients aged 15-64 years with newly diagnosed BCR/ABL1-positive ALL in the single-arm, multicenter study conducted by the Japanese Adult Leukemia Study Group (JALSG), all but one experienced complete remission (CR or CRi) after dasatinib induction (step 1), and 56% achieved molecular complete response (MCR) after intensive consolidation (IC; step 2), Isamu Sugiura, MD, PhD, reported at the annual meeting of the American Society of Hematology.

The MCR rate increased to 66.2% after the first cycle of consolidation, which included high-dose methotrexate/cytarabine followed by 21 days of 100-mg dasatinib (C1), said Dr. Sugiura of the division of hematology and oncology, Toyohashi Municipal Hospital, Japan.

After all cycles of treatment, the MCR rates before and at 30 and 100 days after transplant were 75.9%, 92.7%, and 93.6%, respectively, he added.

The current standard of care of Ph+ALL is tyrosine kinase inhibitor (TKI)-based chemotherapy followed by alloHCT in the first CR, he said noting that deeper MCR at the time of transplant is associated with the best prognosis.

However, early therapy-related mortality, relapse, and non-relapse mortality remain problematic, he said.

JALSG previously reported results from the Ph+ALL202 and Ph+ALL208 studies, which successfully introduced the TKI imatinib into IC followed by alloHCT for newly diagnosed PH+ALL, establishing the standard of care in Japan, Dr. Sugiura said.

“As the next step, Ph+ALL213 was started to evaluate the introduction of dasatinib and two-step chemotherapy,” he said, explaining that 30%-40% of patients in the prior studies were unable to undergo alloHCT at the first CR because of older age, early relapse, or therapy-related death; benefits in Ph+ALL202, for example, were largely seen in patients younger than age 55 years.

Ph+ALL213 was designed to assess to ability of dasatinib to improve efficacy and reduce toxicity in those settings.

Patients with Eastern Cooperative Oncology Group performance status scores of 0-3 and sufficient organ function were enrolled and underwent step 1 (induction), which targeted hematologic complete response (HCR) by day 28 of dasatinib at a dose of 140 mg daily and day 14 of 60 mg/m² of prednisone, followed by step 2 (IC), which targeted MCR by day 28 of 100-mg dasatinib in combination with CALGB BFM-like intensive chemotherapy, Dr. Sugiura said.

Consolidation included four cycles alternating between the C1 methotrexate/cytarabine/dasatinib regimen and a CHOP-like regimen using vincristine/cyclophosphamide/daunorubicin followed by 21 days of 100-mg dasatinib (C2). Maintenance therapy included 12 cycles of 24 days of 100 mg DA with vincristine/prednisone.

Patients who achieved HCR and had an appropriate donor proceeded to alloHCT after the first cycle of C1 (C1-1), and in those who were minimal residual disease (MRD)–positive just before transplantation, 100 mg dasatinib was given for 10 cycles after alloHCT, whereas MRD-negative patients underwent observation.

Toxicities associated with dasatinib included liver dysfunction in 11 patients (14.1%), and pneumonitis with severe allergic reaction in 1 patient, Dr. Sugiura said, adding that no therapy-related mortality was reported.

Overall, 74.4% of patients underwent transplant, which was significantly greater than the 59.6% who did so in the JALSG Ph+ALL202 trial. Other significant differences between the Ph+ALL213 and 202 trials included the rates of related donor transplants (29.3% vs. 50.8%) and use of reduced-intensity conditioning (31.0% vs. 10.2%), respectively, he said.

At a median follow-up of 48.1 months, 3-year event-free survival in the current trial was 66.2%, and overall survival (OS) was 80.5%, and in the 58 patients who underwent transplant at the first CR, the rates, respectively, were 74.1% and 84.5%. In those with MCR they were 79.5% and 90.9%.

Of note, the presence of additional cytogenetic abnormalities at presentation was associated with worse OS (P = .0346), and the effect was greatest when derivative 22 syndrome was present (P = .00174), Dr. Sugiura said.

MRD state at the time of transplant in first CR also was associated with outcomes; 3-year event-free survival was 79.5% in 44 MRD-negative patients, compared with 57.1% in 14 MRD-positive patients, and 3-year overall survival was 90.9% vs. 64.3%, respectively.

“Survival curves for MRD-positive patients were inferior to those for MRD-negative patients not because of hematological relapse, but because of transplant-related mortality caused by therapy-related complications and gastrointestinal acute [graft-versus-host] disease,” he said.

The findings demonstrate that dasatinib-based two-step induction was highly effective and safe as pretransplant therapy, he said, noting that transplant was “maximally used,” and although 16% of patients relapsed, both relapse- and non-relapse-related mortality were minimized, with rates of 8.6% and 10.3%, respectively, after transplant.

Longer observation and a larger study are required to confirm these findings, Dr. Sugiura said, noting that the phase 2 JALSG Ph+ALL219 study will look at the potential for further improving outcomes with the addition of the multitargeted TKI ponatinib in patients who are MRD-positive after IC.

This study was funded by the Ministry of Health, Labor and Welfare of Japan. Dr. Sugiura reported having no disclosures.

ORLANDO – Sevuparin, a novel nonanticoagulant heparinoid drug, showed no efficacy for acute vaso-occlusive crisis (VOC) in patients with sickle cell disease (SCD) in the randomized, controlled, phase 2 TVOC01 trial, but its promising safety and broad mechanism of action warrant further exploration in the prodromal VOC setting, according to investigators.

Dr_Microbe/Thinkstock

Time to VOC resolution – the primary study endpoint – was similar at about 168 hours in 71 hospitalized patients randomized to receive sevuparin and in 76 who received placebo (intention-to-treat hazard ratio, 0.89), Bart J. Biemond, MD, explained during a presentation of the findings at the annual meeting of the American Society of Hematology.

A per-protocol analysis based on the 69 and 75 patients dosed in the treatment and placebo arms, respectively, showed a similar result (HR, 0.81), said Dr. Biemond of the department of clinical hematology, Amsterdam UMC, Academic Medical Center, the Netherlands.

Secondary endpoints, including mean change in pain intensity from baseline on a visual analogue scale (VAS), duration of severest pain measured as time to achieve a 30% reduction in VAS score from baseline, and cumulative use of parenteral opioids, also did not differ between the treatment and placebo arms, he added.

Patients in the global, double-blind, multicenter trial were aged 12-50 years (median, 22 years) with any type of SCD. They were enrolled from 16 sites in 7 countries to receive a loading dose of 3 mg/kg of sevuparin and continuous 18 mg/kg per day infusions or placebo. Patients in both arms also received standard-of-care and parenteral opioid therapy.

The groups were generally balanced with respect to demographic and baseline characteristics, Dr. Biemond said, noting that the treatment was safe: No serious adverse events occurred, and any mild-to-moderate adverse events were transient.

The findings were disappointing given the lack of approved treatment options other than pain management for acute VOC in hospitalized patients with SCD, and they were somewhat surprising given that preclinical and clinical data in recent years have demonstrated that “you can actually prevent those crises by antiadhesive strategies,” he said.

“So we hypothesized that, if you perform such an antiadhesive strategy in a patient already having a crisis and admitted in the hospital, you may shorten their period of admission and perhaps also shorten the severity of their pain,” he said.

In fact, a single-center, randomized, controlled trial conducted by Qari et al. in 2007 (Thromb Haemost. 2007 Aug;98[2]:392-6) showed that full-dose tinzaparin reduced pain severity and duration of admission among sickle cell patients with acute VOC – perhaps because of the antiadhesive properties of heparin – but that study was never repeated, Dr. Biemond said, noting that those antiadhesive properties have been well documented in animal studies.

“Heparin is able to inhibit P-selectin, L-selectin, thrombospondin, fibronectin, and von Willebrand activity, which are all involved in vaso-occlusion in patients with sickle cell disease, and very likely also involved during a vaso-occlusive crisis,” he explained, adding that sevuparin, a low-molecular-weight heparin without functional antithrombin binding domain, seemed to be a good candidate for testing that hypothesis.

“It has no anticoagulant effects on factor Xa and IIa,” he said. “It retains, however, its antiadhesive and antiaggregation properties.”

Since it has no anticoagulation activity, it can be dosed at up to 20-fold the therapeutic dose of low-molecular-weight heparin to optimize the antiadhesive effects, he noted.

However, the data indicate that “antiadhesive therapies are clearly not effective in patients with vaso-occlusive crisis,” he said, noting that this was also affirmed by a similar 2019 study of the investigational panselectin inhibitor rivipansel, as reported in a Pfizer press release.

Intriguingly, the difference between the current study and the 2007 study by Qari et al. raises questions about whether anticoagulation, rather than antiadhesion, helped resolve VOC in that study, he said, noting that future studies should focus on whether that is the case.

As for the role of antiadhesive therapy, the mode of action of sevuparin and the current findings taken together suggest that future studies should also assess whether it can be used to prevent VOC.

“Perhaps sevuparin could be administered to patients in a prodromal phase – just before a real vaso-occlusive crisis appears – to prevent such a crisis from happening,” he said. “It would be interesting to use the drug that way.”

A per-protocol analysis based on the 69 and 75 patients dosed in the treatment and placebo arms, respectively, showed a similar result (HR, 0.81), said Dr. Biemond of the department of clinical hematology, Amsterdam UMC, Academic Medical Center, the Netherlands.

Secondary endpoints, including mean change in pain intensity from baseline on a visual analogue scale (VAS), duration of severest pain measured as time to achieve a 30% reduction in VAS score from baseline, and cumulative use of parenteral opioids, also did not differ between the treatment and placebo arms, he added.

Patients in the global, double-blind, multicenter trial were aged 12-50 years (median, 22 years) with any type of SCD. They were enrolled from 16 sites in 7 countries to receive a loading dose of 3 mg/kg of sevuparin and continuous 18 mg/kg per day infusions or placebo. Patients in both arms also received standard-of-care and parenteral opioid therapy.

The groups were generally balanced with respect to demographic and baseline characteristics, Dr. Biemond said, noting that the treatment was safe: No serious adverse events occurred, and any mild-to-moderate adverse events were transient.

The findings were disappointing given the lack of approved treatment options other than pain management for acute VOC in hospitalized patients with SCD, and they were somewhat surprising given that preclinical and clinical data in recent years have demonstrated that “you can actually prevent those crises by antiadhesive strategies,” he said.

“So we hypothesized that, if you perform such an antiadhesive strategy in a patient already having a crisis and admitted in the hospital, you may shorten their period of admission and perhaps also shorten the severity of their pain,” he said.

In fact, a single-center, randomized, controlled trial conducted by Qari et al. in 2007 (Thromb Haemost. 2007 Aug;98[2]:392-6) showed that full-dose tinzaparin reduced pain severity and duration of admission among sickle cell patients with acute VOC – perhaps because of the antiadhesive properties of heparin – but that study was never repeated, Dr. Biemond said, noting that those antiadhesive properties have been well documented in animal studies.

“Heparin is able to inhibit P-selectin, L-selectin, thrombospondin, fibronectin, and von Willebrand activity, which are all involved in vaso-occlusion in patients with sickle cell disease, and very likely also involved during a vaso-occlusive crisis,” he explained, adding that sevuparin, a low-molecular-weight heparin without functional antithrombin binding domain, seemed to be a good candidate for testing that hypothesis.

“It has no anticoagulant effects on factor Xa and IIa,” he said. “It retains, however, its antiadhesive and antiaggregation properties.”

Since it has no anticoagulation activity, it can be dosed at up to 20-fold the therapeutic dose of low-molecular-weight heparin to optimize the antiadhesive effects, he noted.

However, the data indicate that “antiadhesive therapies are clearly not effective in patients with vaso-occlusive crisis,” he said, noting that this was also affirmed by a similar 2019 study of the investigational panselectin inhibitor rivipansel, as reported in a Pfizer press release.

Intriguingly, the difference between the current study and the 2007 study by Qari et al. raises questions about whether anticoagulation, rather than antiadhesion, helped resolve VOC in that study, he said, noting that future studies should focus on whether that is the case.

As for the role of antiadhesive therapy, the mode of action of sevuparin and the current findings taken together suggest that future studies should also assess whether it can be used to prevent VOC.

“Perhaps sevuparin could be administered to patients in a prodromal phase – just before a real vaso-occlusive crisis appears – to prevent such a crisis from happening,” he said. “It would be interesting to use the drug that way.”

Patients with nonalcoholic fatty liver disease (NAFLD) in a prospective observational study had a twofold increase in cardiovascular events, NAFLD patients with liver fibrosis had a fourfold increase in risk, and liver fibrosis scores predicted risk.

At median follow-up of 41.4 months representing 3,044.4 person-years of observation in the Progression of Liver Damage and Cardiometabolic Disorders in NAFLD (PLINIO) study, 58 cardiovascular events (CVEs) were reported in 898 consecutive outpatients who were screened for liver steatosis by ultrasound. The annual rate of CVEs among 643 patients with NAFLD was 2.1%, compared with 1.0% among 255 patients without NAFLD, according to Francesco Baratta, MD, of Clinica Medica, Sapienza University of Rome, and colleagues. Their report is in Clinical Gastroenterology and Hepatology.

The difference did not meet a priori thresholds for statistical significance (P = .066), but became significant after exclusion of new-onset atrial fibrillation events (annual CVE rates of 1.9% vs. 0.7%; P = .034), and on multivariate analysis, age, male sex, and NAFLD were found to be independently associated with CVE occurrence (hazard ratios, 1.07, 3.20, and 2.73, respectively), the investigators found.

In NAFLD patients, a NAFLD fibrosis score (NFS) greater than 0.676 was significantly associated with CVEs after adjustment for comorbidities (HR, 2.29), and a Fibrosis-4 (FIB-4) score greater than 2.67, a history of cardiovascular disease, and metabolic syndrome predicted incident CVEs (HRs, 4.57, 2.95, and 2.30, respectively). The findings were similar after exclusion of new-onset atrial fibrillation from the composite endpoint (HRs, 2.42 and 4.00, respectively).

“Furthermore, when we analyzed only patients without CVEs at baseline, we found a similar association between liver fibrosis and CVEs,” the researchers wrote, noting that the adjusted HRs for NFS were 2.50 and 4.28, respectively.

In addition to liver-related complications, patients with NAFLD are known to have an increased CVE risk, and while liver fibrosis severity is used to determine prognosis, not all patients can undergo a liver biopsy to assess fibrosis. Therefore, there is a need to identify and validate noninvasive markers of liver fibrosis, but few data exist with respect to the predictive role of noninvasive scoring on CVEs, they said.

The findings of this study suggest the use of the NFS and FIB-4 score may reduce the need for liver biopsy by identifying NAFLD patients at higher risk of having advanced liver fibrosis. They further suggest that liver fibrosis development in patients with NAFLD “may be the result of a long-term exposure to cardiometabolic risk factors such as diabetes,” and that “the concomitant presence of multiple cardiometabolic conditions may induce a chronic low-grade proinflammatory and pro-oxidant status leading to liver inflammation (i.e., macrophage activation) and collagen deposition.”

The findings may also have clinical implications: “The association between liver fibrosis and cardiovascular risk supports a potential role for statin treatment in patients with NAFLD,” they explained.

ORLANDO – Adding rituximab to standard induction chemotherapy in adults with precursor B-cell acute lymphoblastic leukemia (B-ALL) appears to improve event-free survival, but four doses are insufficient, according to the first analysis from the randomized, phase 3 UKALL14 trial.

VashiDonsk/Creative Commons/CC ASA 3.0

The findings also suggest that the significant event-free survival (EFS) benefit of adding 16-18 doses of rituximab in B-ALL patients, as demonstrated in “the recent and very important” GRAALL-2005/R study, may be generalizable to B-precursor ALL patients regardless of Philadelphia (Ph) chromosome status or CD20-positive expression level, Adele K. Fielding, MBBS, PhD, reported at the annual meeting of the American Society of Hematology.

Unlike GRAALL-2005/R (NCT00327678), which included only patients with greater than 20% of ALL blasts expressing CD20 and with Ph-negative ALL, UKALL14 (NCT01085617) included B-ALL patients regardless of Ph chromosome status or CD20 expression level, explained Dr. Fielding of the Cancer Institute, University College London.

Overall, EFS rates among patients in the UKALL14 study at a median follow-up of 40.5 months were 41.9% in 288 patients randomized to receive standard-of-care chemotherapy (SOC), and 48.7% among 289 randomized to receive SOC plus rituximab, but the difference was not statistically significant (hazard ratio, 0.88; P = .28), she said.

“Likewise there was a nonsignificant improvement in 3-year event-free survival and in median event-free survival in the rituximab arms, but these differences did not meet our predetermined criteria,” she added.

Similarly, the overall survival findings showed slight, but non–statistically significant improvement in the rituximab arms (HR, 0.9; P = .39). The 3-year and median overall survival outcomes appeared to favor rituximab, but “this was not the magnitude of benefit that we were seeking in our study,” she said.

However, while a preplanned subgroup analysis by cytogenetic and other risk groups, as well as by cell surface CD20 expression, did not reveal any significant interactions for EFS, they did show that the percentage of blasts expressing CD20 was a strong independent poor prognostic factor.

A cutoff of 11.6%, compared with the 20% typically used, was found to be ideal based on the Youden Index, which determines the best balance between sensitivity and specificity.

“Interestingly, in addition to this, we did not find any impact of CD20 expression on response to rituximab,” Dr. Fielding noted.

Further, outcomes analyses by post–induction treatment assignment showed that, in patients who received myeloablative allogeneic stem cell transplant, “there was a large and statistically significant benefit to [adding rituximab], she said.

Landmark analysis showed an EFS hazard ratio of 0.48 at the time of transplant (P = .037), she said, noting that the SOC and SOC plus rituximab arms were well matched among this subset of patients.

The difference appeared to relate to relapse risk (HR, .38), but on an intention-to-treat analysis including all patients under age 40 years, the difference was “no longer quite so pronounced.”

“We do not understand the biological basis for this finding,” Dr. Fielding said, noting that it wasn’t explained by differences in graft-versus-host disease or infection. “This difference was not apparent in patients who received or were intended to receive reduced-intensity allogeneic conditioning.”

A multivariable analysis did not show a significant treatment effect, but did show “the same trend toward a better outcome in the rituximab arm,” she added.

UKALL14 subjects were adults aged 25-65 years with de novo ALL, regardless of Ph status or cell surface CD20 expression, who were recruited from 70 centers in the United Kingdom between December 2010 and July 2017. Those randomized to standard of care received a standard four-drug induction after a steroid prephase – with or without four doses of rituximab.

After a second induction, patients underwent risk assessment; low-risk patients were treated on the SOC arm and received high-dose methotrexate and additional pegylated asparaginase followed by four cycles of consolidation therapy. This was followed by 2 years of maintenance treatment.

High-risk patients with a sibling or fully matched unrelated donor available underwent allogeneic stem cell transplant, with those aged 40 years and younger receiving myeloablative conditioning and those over 40 years receiving reduced-intensity conditioning.

Most patients in the SOC plus rituximab arm received all four doses of rituximab, and the treatment arms were well-balanced with respect to risk characteristics, Dr. Fielding said, adding that no differences were noted in adverse events or mortality between the arms.

There is strong rationale for studying rituximab in ALL, she noted. For example, rituximab is safe to add to chemotherapy, and it has potential relevance at any level of CD20 expression, she said, explaining the basis for the study. Indeed, the findings support its use in this setting.

“Rituximab benefits patients with ALL,” she said. “But in our hands, four doses is insufficient to realize the full benefit.”

Etiologies, demographics, management, and outcomes vary widely among patients with acute pancreatitis around the world, according to an analysis of data from the prospective, international APPRENTICE patient registry.

In some cases – particularly in regard to therapeutic interventions – the differences are “strikingly divergent” and demonstrate a “lag behind current evidence,” Bassem Matta, MD, of the University of Pittsburgh Medical Center, and colleagues reported in Clinical Gastroenterology and Hepatology.

Findings of a disproportionately higher rate of opioid prescribing during hospitalization and at discharge at North American sites are especially alarming, the investigators said.
 

Demographics and etiologies

The most common etiologies among 1,612 patients in the registry, which collects data from individuals with acute pancreatitis at six centers in Europe, three centers in India, five centers in Latin America, and eight centers in North America, were biliary (45%) and alcoholic (21%), and severity was mild in 65% of patients, moderate in 23%, and severe in 12%, they noted.

The predominant etiology in Latin America was biliary (78%), whereas the predominant etiology in India was alcoholic (45%).

The mean age of patients in Europe was 58 years, which is older than the mean age of 46 years for all regions represented in the registry, and comorbid conditions were also more common among patients in Europe (73% vs. 50% overall), the investigators found.

In addition to age differences, significant geographic differences were seen with respect to sex, ethnicity, and race distributions. Patients from Indian sites, for example, were mostly men (75%), were younger in age (median, 39 years), and were more likely to have alcoholic etiology (45% vs. 14% in the other areas). Most of the Latin American patients were women (67%), were young (median, 43 years), and most often had biliary etiology (78% vs. 37% elsewhere).

In contrast, European and North American subjects had a relatively equal sex distribution and an overall older age (median, 58 years).

“Observed differences in etiology and demographics likely reflect a tight interconnection between age, sex, and etiology,” the investigators wrote.
 

Management

Analgesic utilization was “markedly variable” across the world, they said, explaining that nonsteroidal anti-inflammatory drugs (NSAIDs) were the mainstay of pain management in Europe (68%), whereas Indian sites used tramadol in 91% of patients.

Latin American centers frequently used opioids (59%), NSAIDs (48%), and tramadol (34%).

However, opioid analgesics were used in 93% of patients in North America, compared with 27% of patients in the other regions, and 64% vs. 2.7% of patients in North American vs. the other regions were discharged on opioid analgesics.

This is of particular concern in light of a meta-analysis showing no difference in efficacy between opioids and nonsteroidal anti-inflammatory drugs for pain control in acute pancreatitis, the investigators said, noting that “[i]t is not entirely clear why such divergences exist between North American centers compared to the rest of the world.

“Notably, no clear statements are included in the current societal guidelines addressing optimal strategies for analgesia in [acute pancreatitis],” they added.

Also of note, the rate of endoscopic retrograde cholangiopancreatography (ERCP) – which guidelines based on strong evidence say should be limited to urgent cases among biliary acute pancreatitis patients with suspected cholangitis or biliary obstruction – was much higher at North American sites (44.7% vs. 21.9% overall) and post-ERCP pancreatitis was significantly more common at North American sites (19% vs. 2.8% in the other geographic areas), they said.

However, these differences were mostly driven by two North American sites, which classified 50 out of 90 and 22 out of 62 enrolled patients, respectively, as having post-ERCP pancreatitis.

Further, cholecystectomies were performed at the time of hospital admission in 60% of patients in Latin America, compared with 15% overall.

Another notable difference in management related to intravenous fluid use; similar amounts were administered during the first 24 hours in India and Latin America (3-3.2 liters), but in Europe the average was 2.5 liters, and while lactated Ringers and normal saline were the main types of fluid used, lactated Ringers was the dominant type used in India (92%), but was rarely used in Latin America (7%).
 

Outcomes

The overall median length of stay was 8 days, and overall mortality during hospitalization was 2.8%. In patients with mild disease, the shortest lengths of stay were in North America (4 vs. 7 days in other regions), and severe disease was more common in India (23% vs. 9% elsewhere).

Intensive care unit admissions were highest at Indian centers, and in-hospital mortality was highest in Europe (5.7%), compared with 3.3% in India, 2.3% in Latin America, and 0.6% in North America, they said.

Mortality during the initial hospital stay among patients with severe acute pancreatitis was 44% in Europe, compared with 15% in the other three regions.

Multivariable regression analyses adjusting for potential confounders such as age, sex, body mass index, Charlson score, etiology, and transfer status showed that the odds of severe acute pancreatitis were 11.2 times higher in Europe, 7 times higher in India, and 5.6 times higher in Latin America, compared with North America.

The odds ratios for mortality during hospitalization among patients with severe disease were 10.4 in Europe, 4.2 in India, and 8.3 in Latin America, compared with North America.
 

Implications of the findings

Around the world, acute pancreatitis is a leading cause of gastrointestinal-related hospital admissions, and incidence is reportedly increasing in the United States and Europe, the investigators said, noting that about 20% of patients develop severe disease with relatively high morbidity and mortality.

Multiple advances in management have emerged over the last decade, but it is unclear whether those recent advances have gained traction worldwide, they added.

The APPRENTICE registry was created as a response to the lack of prospective, multinational data and the current study aimed to assess the geographic differences in patient characteristics, management, and outcomes across four geographic areas.

The findings, which represent “a bird’s eye view” of regional variation, underscore a need for “adequately powered, multicenter, randomized controlled trials comparing the efficacy of different fluid resuscitation protocols” in acute pancreatitis patients, the investigators said.

Further, “the interventions specific to each region are in certain aspects strikingly divergent, and in many occasions lag behind current evidence,” they wrote, noting the largely variable length-of-stay outcomes and mortality rates.

“In addition to depicting key features of [acute pancreatitis], the results from this study may serve as a reference guide for designing future clinical trials,” they concluded.

Etiologies, demographics, management, and outcomes vary widely among patients with acute pancreatitis around the world, according to an analysis of data from the prospective, international APPRENTICE patient registry.

In some cases – particularly in regard to therapeutic interventions – the differences are “strikingly divergent” and demonstrate a “lag behind current evidence,” Bassem Matta, MD, of the University of Pittsburgh Medical Center, and colleagues reported in Clinical Gastroenterology and Hepatology.

Findings of a disproportionately higher rate of opioid prescribing during hospitalization and at discharge at North American sites are especially alarming, the investigators said.
 

Demographics and etiologies

The most common etiologies among 1,612 patients in the registry, which collects data from individuals with acute pancreatitis at six centers in Europe, three centers in India, five centers in Latin America, and eight centers in North America, were biliary (45%) and alcoholic (21%), and severity was mild in 65% of patients, moderate in 23%, and severe in 12%, they noted.

The predominant etiology in Latin America was biliary (78%), whereas the predominant etiology in India was alcoholic (45%).

The mean age of patients in Europe was 58 years, which is older than the mean age of 46 years for all regions represented in the registry, and comorbid conditions were also more common among patients in Europe (73% vs. 50% overall), the investigators found.

In addition to age differences, significant geographic differences were seen with respect to sex, ethnicity, and race distributions. Patients from Indian sites, for example, were mostly men (75%), were younger in age (median, 39 years), and were more likely to have alcoholic etiology (45% vs. 14% in the other areas). Most of the Latin American patients were women (67%), were young (median, 43 years), and most often had biliary etiology (78% vs. 37% elsewhere).

In contrast, European and North American subjects had a relatively equal sex distribution and an overall older age (median, 58 years).

“Observed differences in etiology and demographics likely reflect a tight interconnection between age, sex, and etiology,” the investigators wrote.
 

Management

Analgesic utilization was “markedly variable” across the world, they said, explaining that nonsteroidal anti-inflammatory drugs (NSAIDs) were the mainstay of pain management in Europe (68%), whereas Indian sites used tramadol in 91% of patients.

Latin American centers frequently used opioids (59%), NSAIDs (48%), and tramadol (34%).

However, opioid analgesics were used in 93% of patients in North America, compared with 27% of patients in the other regions, and 64% vs. 2.7% of patients in North American vs. the other regions were discharged on opioid analgesics.

This is of particular concern in light of a meta-analysis showing no difference in efficacy between opioids and nonsteroidal anti-inflammatory drugs for pain control in acute pancreatitis, the investigators said, noting that “[i]t is not entirely clear why such divergences exist between North American centers compared to the rest of the world.

“Notably, no clear statements are included in the current societal guidelines addressing optimal strategies for analgesia in [acute pancreatitis],” they added.

Also of note, the rate of endoscopic retrograde cholangiopancreatography (ERCP) – which guidelines based on strong evidence say should be limited to urgent cases among biliary acute pancreatitis patients with suspected cholangitis or biliary obstruction – was much higher at North American sites (44.7% vs. 21.9% overall) and post-ERCP pancreatitis was significantly more common at North American sites (19% vs. 2.8% in the other geographic areas), they said.

However, these differences were mostly driven by two North American sites, which classified 50 out of 90 and 22 out of 62 enrolled patients, respectively, as having post-ERCP pancreatitis.

However, opioid analgesics were used in 93% of patients in North America, compared with 27% of patients in the other regions, and 64% vs. 2.7% of patients in North American vs. the other regions were discharged on opioid analgesics.

This is of particular concern in light of a meta-analysis showing no difference in efficacy between opioids and nonsteroidal anti-inflammatory drugs for pain control in acute pancreatitis, the investigators said, noting that “[i]t is not entirely clear why such divergences exist between North American centers compared to the rest of the world.

“Notably, no clear statements are included in the current societal guidelines addressing optimal strategies for analgesia in [acute pancreatitis],” they added.

Also of note, the rate of endoscopic retrograde cholangiopancreatography (ERCP) – which guidelines based on strong evidence say should be limited to urgent cases among biliary acute pancreatitis patients with suspected cholangitis or biliary obstruction – was much higher at North American sites (44.7% vs. 21.9% overall) and post-ERCP pancreatitis was significantly more common at North American sites (19% vs. 2.8% in the other geographic areas), they said.

However, these differences were mostly driven by two North American sites, which classified 50 out of 90 and 22 out of 62 enrolled patients, respectively, as having post-ERCP pancreatitis.

Further, cholecystectomies were performed at the time of hospital admission in 60% of patients in Latin America, compared with 15% overall.

Another notable difference in management related to intravenous fluid use; similar amounts were administered during the first 24 hours in India and Latin America (3-3.2 liters), but in Europe the average was 2.5 liters, and while lactated Ringers and normal saline were the main types of fluid used, lactated Ringers was the dominant type used in India (92%), but was rarely used in Latin America (7%).
 

Outcomes

The overall median length of stay was 8 days, and overall mortality during hospitalization was 2.8%. In patients with mild disease, the shortest lengths of stay were in North America (4 vs. 7 days in other regions), and severe disease was more common in India (23% vs. 9% elsewhere).

Intensive care unit admissions were highest at Indian centers, and in-hospital mortality was highest in Europe (5.7%), compared with 3.3% in India, 2.3% in Latin America, and 0.6% in North America, they said.

Mortality during the initial hospital stay among patients with severe acute pancreatitis was 44% in Europe, compared with 15% in the other three regions.

Multivariable regression analyses adjusting for potential confounders such as age, sex, body mass index, Charlson score, etiology, and transfer status showed that the odds of severe acute pancreatitis were 11.2 times higher in Europe, 7 times higher in India, and 5.6 times higher in Latin America, compared with North America.

The odds ratios for mortality during hospitalization among patients with severe disease were 10.4 in Europe, 4.2 in India, and 8.3 in Latin America, compared with North America.
 

Implications of the findings

Around the world, acute pancreatitis is a leading cause of gastrointestinal-related hospital admissions, and incidence is reportedly increasing in the United States and Europe, the investigators said, noting that about 20% of patients develop severe disease with relatively high morbidity and mortality.

Multiple advances in management have emerged over the last decade, but it is unclear whether those recent advances have gained traction worldwide, they added.

The APPRENTICE registry was created as a response to the lack of prospective, multinational data and the current study aimed to assess the geographic differences in patient characteristics, management, and outcomes across four geographic areas.

The findings, which represent “a bird’s eye view” of regional variation, underscore a need for “adequately powered, multicenter, randomized controlled trials comparing the efficacy of different fluid resuscitation protocols” in acute pancreatitis patients, the investigators said.

Further, “the interventions specific to each region are in certain aspects strikingly divergent, and in many occasions lag behind current evidence,” they wrote, noting the largely variable length-of-stay outcomes and mortality rates.

“In addition to depicting key features of [acute pancreatitis], the results from this study may serve as a reference guide for designing future clinical trials,” they concluded.

ORLANDO – A front-line chemotherapy-free induction-consolidation protocol that combines dasatinib and blinatumomab for the treatment of Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ ALL) resulted in high survival and molecular response rates in the phase 2 D-ALBA trial.

Sharon Worcester/MDedge News

At a median follow-up of 14.3 months, 61 of 63 patients enrolled in the multicenter trial had completed induction with the second-generation tyrosine kinase inhibitor (TKI) dasatinib, 60 had received the first cycle of treatment with the bispecific monoclonal antibody blinatumomab, and 56, 45, 36, and 25 had received second, third, fourth, and fifth cycles of blinatumomab, respectively, Sabina Chiaretti, MD, PhD, reported at the annual meeting of the American Society of Hematology.

The molecular response rate at the end of induction on day 85 was 29%, said Dr. Chiaretti of the department of translational and precision medicine, Sapienza University, Rome.

“Even more importantly, at the primary endpoint [the end of the second cycle of blinatumomab], 60% of patients were molecular responders,” she said.

Of note, the molecular response rate continued to increase with additional blinatumomab cycles; the rate was 79% after cycle 4, she said.

The overall survival (OS) and disease-free survival (DFS) rates also were “very exciting and promising” at 92.5% and 89.7%, respectively, she added.

DFS did not differ significantly based on molecular response at day 85 (100% vs. 87.4% in those with vs. without a molecular response; P = .154), but patients with p190 fusion protein had slightly worse DFS, compared with those who had p210 or both p190 and p210 fusion protein (83.5% vs. 100%; P = .48).

Study participants included adult Ph+ ALL patients with a median age of 54.5 years (range of 24.1-81.7 years) who were enrolled between May 2017 and January 2019; 54% were women and the median white blood cell count was 42 x10⁹/L.

The percentage of study subjects with the p190, p210, and both p190/p210 fusion proteins was 65.1%, 27%, and 7.9% respectively, Dr. Chiaretti said.

Treatment included dasatinib at a dose of 140 mg/day as induction for 85 days along with steroids, which were started 7 days prior to induction and continued for a total of 31 days. Those who had a complete hematologic response (CHR) after induction received postinduction consolidation treatment with blinatumomab at a flat dose of 28 mcg/day for at least 2 cycles, and up to 3 additional cycles were allowed at physician discretion based on molecular response.

During the course of the study, 156 adverse events occurred, including 50 serious adverse events. The latter most often involved infections, including 6 cytomegalovirus infections and 6 cases of prolonged fever; one of those cases was likely related to blinatumomab.

Two patients died, including an 80-year-old woman who died during induction, and a patient who was in CHR. Six relapses occurred, including one that involved a major protocol violation; three were extramedullary.

Additional analyses in this study showed that the most frequent copy number aberration was, as expected based on the available literature, IKZF1 deletion, which was present in 25 of 46 available samples (54%). Of those, 11 (23.9%) were found to have the IKZF1-plus signature, defined as IKZF1 and/or PAX5 and/or CDKN2A/B deletions, she said.

Further, ABL1 mutational analysis conducted in 15 patients with evidence of MRD increase showed that 8 were wild type and 7 were mutated – with 6 of the 7 represented by the gatekeeper mutation T315I, and one by an E255K mutation. All but 1 mutation occurred in p190 cases prior to the start of blinatumomab.

Of note, and in line with prior findings, blinatumomab was effective for reducing or eradicating the MRD levels in these difficult-to-treat patients, Dr. Chiaretti said.

An analysis of the immunologic compartment carried out in 12 patients who completed all 5 cycles of blinatumomab showed a significant increase in the rate of CD8+ T cells (29% vs. 19.8% before the start of blinatumomab; P = .04) and a significant reduction in the rate of Tregs (3.7% vs. 11% before blinatumomab; P = .02), she added.

The findings of this study to date – with some patients having more than 2 years of follow-up – are notable given the high rates of molecular response and survival, Dr. Chiaretti said.

Outcomes in patients with Ph+ ALL were generally poor before the introduction of TKIs, but “the scenario completely changed,” she explained.

“In general, all TKI-based treatments – with or without chemotherapy – have led to overall survival rates in the range of 50% ... which means that we still need to improve our clinical management,” she said. “Another finding that became clear is the fact that patients who achieve MRD-negative status have a significantly better outcome than those who do not.”

The D-ALBA trial was designed with the aim of increasing the rate of MRD negativity in newly diagnosed patients using dasatinib and blinatumomab, and the results demonstrate that this chemotherapy-free induction/consolidation approach is feasible in the front-line setting for adult Ph+ ALL patients, she said, adding that “it is strongly effective in inducing high rates of MRD negativity, and it results in much better survival rates.”

The findings with respect to IKZF1-plus cases and ABL1 mutations underscore the need for further work, she said.

“We still have to face some challenging cases,” she explained. “This study, as others before, really proves that IKZF1-plus cases are very difficult to treat; they require intensification and probably alternative strategies.”

Dr. Chiaretti reported membership on a board of directors or advisory committee for Pfizer, Incyte, Amgen, and Shire.

Cognitive and neuropsychological impairment associated with extremely preterm (EP) birth persists into young adulthood, according to findings from the 1995 EPICure cohort.

Melissa pisani/iStock/Getty Images Plus

Of note, intellectual impairment increased significantly after the age of 11 years among 19-year-olds in the cohort of individuals born EP, Helen O’Reilly, PhD, of the Institute for Women’s Health at University College London and colleagues reported in Pediatrics.

Neuropsychological assessment to examine general cognitive abilities, visuomotor abilities, prospective memory, and certain aspects of executive functioning and language in 127 cases and 64 term-born controls showed significantly lower scores across all tests in those born EP.

Impairment in at least one neuropsychological domain was present in 60% of EP birth cases (compared with 21% of controls), with 35% having impairment in at least four domains. Most deficits occurred in general cognitive function and/or visuomotor abilities.

Further, those who scored in the intellectual disability range at 11 years were more likely to score in that range at 19 years (relative risk, 8.72), and those with cognitive impairment at 11 years were at increased risk of deficit at 19 years (RR, 3.56), even after adjustment for sex and socioeconomic status, the authors wrote.

None of the term-born controls had a cognitive impairment at 11 years, and two (3%) had impairment at 19 years.

Studies of adults born very preterm have revealed that these individuals are at risk for neuropsychological impairment, but the extent of such impairment in individuals with EP birth, defined as birth before 26 weeks’ gestation, had not previously been studied in the long term.

Assessments in the EPICure cohort of individuals born EP in 1995 previously showed scores at 1.1-1.6 standard deviations lower on measures of general cognitive function, compared with standardized norms and/or term-born controls, at age 2.5, 6, and 11 years, Dr. O’Reilly and colleagues explained.

The current findings indicate that general cognitive and neuropsychological functioning problems associated with EP birth persist and can increase into early adulthood, and they “highlight the need for early and ongoing neuropsychological and educational assessment in EP children to ensure these children receive appropriate support in school and for planned educational pathways,” the investigators concluded.

In an accompanying editorial, Louis A. Schmidt, PhD, and Saroj Saigal, MD, of McMaster University, Hamilton, Ont., wrote that these findings “provide compelling evidence for persistent effects of cognitive impairments” in individuals born EP.

They highlighted three lessons from the study:

• It is important to control for anxiety in future studies like this “to eliminate potential confounding influences of anxiety when examining performance-based measures in the laboratory setting,” as individuals born EP are known to exhibit anxiety.
• Group heterogeneity also should be considered, as all survivors of prematurity are not alike.
• Measurement equivalency should be established between groups.

With respect to the latter, “although many of the measures used by O’Reilly et al. have been normed, issues of measurement invariance have not been established between EP and control groups on some of the measures reported,” Dr. Schmidt and Dr. Saigal wrote, noting that “many other studies [also] fail to consider this fundamental measurement property.”

“Considering issues of measurement equivalency is of critical importance to ensuring unbiased interpretations of findings,” they added, concluding that the findings by O’Reilly et al. represent an important contribution and confirm findings from many prior studies of extreme prematurity, which “informs how we effectively manage these problems.”

“As the percentage of preterm birth continues to rise worldwide, coupled with reduced morbidity and mortality, and with more EP infants reaching adulthood, there is a need for prospective, long-term outcome studies of extreme prematurity,” Dr. Schmidt and Dr. Saigal added.

In an accompanying editorial, Louis A. Schmidt, PhD, and Saroj Saigal, MD, of McMaster University, Hamilton, Ont., wrote that these findings “provide compelling evidence for persistent effects of cognitive impairments” in individuals born EP.

They highlighted three lessons from the study:

• It is important to control for anxiety in future studies like this “to eliminate potential confounding influences of anxiety when examining performance-based measures in the laboratory setting,” as individuals born EP are known to exhibit anxiety.
• Group heterogeneity also should be considered, as all survivors of prematurity are not alike.
• Measurement equivalency should be established between groups.

With respect to the latter, “although many of the measures used by O’Reilly et al. have been normed, issues of measurement invariance have not been established between EP and control groups on some of the measures reported,” Dr. Schmidt and Dr. Saigal wrote, noting that “many other studies [also] fail to consider this fundamental measurement property.”

“Considering issues of measurement equivalency is of critical importance to ensuring unbiased interpretations of findings,” they added, concluding that the findings by O’Reilly et al. represent an important contribution and confirm findings from many prior studies of extreme prematurity, which “informs how we effectively manage these problems.”

“As the percentage of preterm birth continues to rise worldwide, coupled with reduced morbidity and mortality, and with more EP infants reaching adulthood, there is a need for prospective, long-term outcome studies of extreme prematurity,” Dr. Schmidt and Dr. Saigal added.

The study was funded by the Medical Research Council United Kingdom. The authors reported having no relevant financial disclosures. The editorial by Dr. Schmidt and Dr. Saigal, who also reported having no relevant financial disclosures, was supported by the Canadian Institutes of Health Research.
