Key clinical point: Gene mutations involving ASXL1 were significantly associated with increased risk of vascular events in adults with myelodysplastic syndrome, but Trisomy 8 appeared to have a protective effect.

Major finding: Overall, the incidence of vascular disease in the study population was 27%; mutations in the ASXL1 in particular were significant predictors of vascular disease in multivariate analysis (odds ratio 4.2); however, both elevated ferritin and Trisomy 8 were significantly associated with a lower risk of vascular disease in low-risk MDS patients (P = .043 and P = .036, respectively).

Study details: The data come from a retrospective analysis of 236 MDS patients aged 18 years and older who were seen and treated at a single center between 2010 and 2018.

Disclosures: The study received no outside funding. The researchers had no financial conflicts to disclose.

Key clinical point: Myelodysplastic syndrome patients who had a slower luspatercept apparent clearance (CL/F) were more likely to achieve erythroid responses, suggesting potential as an early efficacy marker.

Major finding: Luspatercept given over a dose range of 0.125 mg/kg-1.75 mg/kg yielded linear and time-invariant pharmacokinetics when given to MDS patients with anemia subcutaneously once every 3 weeks; the odds of transfusion independence at a minimum of 8 weeks increased with time-averaged exposure and plateaued at 1.0 mg/kg-1.75 mg/kg.

Study details: The data come from a review of several studies including 260 adults with anemia caused by myelodysplastic syndromes.

Disclosures: The studies in the review were funded by Bristol Myers Squibb or Acceleron. Lead author Dr. Chen and several coauthors are employees of Bristol Myers Squibb.

Key clinical point: Approximately half of transfusion-dependent MDS patients said they had not discussed ways to reduce the need for transfusions with their doctors and 74% said there were no alternatives to blood transfusions.

Major finding: Among adults with MDS, those with disease duration less than 5 years cited transfusion reactions as their greatest concern; those with longer disease duration cited iron overload. However, a majority of 71% of the patients ranked their quality of life as good or excellent. MDS physicians reported that they would be most likely to offer blood transfusions as primary therapy to patients who were older than 80 years, frail, had lower risk MDS, or had other significant comorbidities.

Study details: The data come from a pair of cross-sectional surveys including 157 myelodysplastic syndrome (MDS) patients and 109 MDS physicians.

Disclosures: The study was supported by the Aplastic Anemia and MDS International Foundation through a grant from Celgene. Lead author Dr. King was supported in part by The Maren Research Award Scholarship through the University of Florida.

Key clinical point: Adults with end-stage renal disease who underwent dialysis for at least six months were at significantly increased risk for MDS compared with healthy controls.

Major finding: Patients with chronic renal failure who underwent dialysis were significantly more likely to develop myelodysplastic syndrome compared to healthy controls (subdistribution hazard ratio 1.60); older age also was significantly associated with increased MDS risk (sHR 1.03).

Study details: The data come from a study of 74,712 adults with chronic renal failure diagnoses between 1997 and 2013 who underwent dialysis, and matched controls. Participants were follow from index date to the first occurrence of MDS, withdrawal from the NHI program, or the last day of 2013.

The days of using chemotherapy to treat Philadelphia chromosome–positive acute lymphoblastic leukemia (Ph+ ALL) may be numbered.

In a phase 2 trial, upfront chemotherapy-free induction/consolidation with the tyrosine kinase inhibitor dasatinib (Sprycel) and the bispecific T-cell engager antibody blinatumomab (Blincyto) yielded high rates of molecular response, “impressive” survival at 18 months, and few toxic effects of grade 3 or higher, say researchers.

With this approach, “60% of adult Ph+ ALL patients, of all ages, can obtain a molecular response, and this percent can increase further with more cycles of blinatumomab,” lead researcher Robin Foà, MD, from Sapienza University of Rome, said in an interview.

“The rates of disease-free survival and overall survival at 18 months are highly favorable, and the protocol is associated with limited toxicity,” Dr. Foà added.

“I see this chemo-free approach becoming a realistic approach for a substantial proportion of adult Ph+ ALL patients, particularly for the older patients, keeping in mind that the incidence of Ph+ ALL increases with age,” Dr. Foà said.

The results of the study were published Oct. 22 in the New England Journal of Medicine.
 

‘Innovative’ and ‘highly successful’

This “innovative” chemotherapy-free approach proved “highly successful” with “surprisingly” few toxic effects, Dieter Hoelzer, MD, PhD, University of Frankfurt (Germany), wrote in a linked editorial.

The Italian GIMEMA LAL2116 D-ALBA trial enrolled 63 adults (median age, 54 years; range, 24-82 years) with newly diagnosed Ph+ ALL. All patients received a glucocorticoid for 31 days beginning 7 days before starting treatment with dasatinib.

Dasatinib (140 mg once daily) induction therapy lasted 85 days. All patients who completed the induction phase received blinatumomab (28 mcg/d) consolidation therapy. Dexamethasone (20 mg) was administered before each blinatumomab cycle. To prevent central nervous system adverse events, levetiracetam (500 mg twice daily) was administered.

All but two patients completed dasatinib induction. One was a 73-year-old woman who withdrew from the trial because of toxic effects after 10 days of dasatinib treatment. She later died of pneumonia. The other was an 82-year-old woman who had a complete hematologic response but left the trial because of pneumonia and pneumonitis.

At the end of the induction phase, 98% of the patients (62 of 63) had a complete hematologic response, including the patient with a complete hematologic response who withdrew; 29% (17 of 59 patients) had a molecular response.

Of the 61 patients who completed the induction phase, 58 received one cycle of blinatumomab, 56 received two cycles, 45 received three cycles, 37 received four cycles, and 29 received five cycles. At the end of the second blinatumomab cycle, 60% of the patients (33 of 55 patients) had a molecular response.

The percentage of patients with a molecular response increased further after receiving additional cycles of blinatumomab – to 70% (28 of 40 patients) after the third cycle, 81% (29 of 36 patients) after the fourth cycle, and 72% (21 of 29 patients) after the fifth cycle.

At a median follow-up of 18 months, overall survival was 95%, and disease-free survival was 88%.

There were no significant differences in DFS between patients with p190-kd fusion protein (85%) and those with p210-kd fusion protein (95%). However, DFS was lower in patients with IKZF1 deletion plus additional genetic aberrations (CDKN2A or CDKN2B, PAX5, or both).

ABL1 mutations were present in six patients who had increased minimal residual disease during induction therapy. All these mutations were cleared by blinatumomab.

There were six relapses, of which three were hematologic. One occurred in a patient with a major protocol violation (a delay of more than 2 months in receiving blinatumomab), one occurred after 12 months in the patient who discontinued the trial after receiving dasatinib for 12 days, and one occurred in a patient after the second cycle of blinatumomab.

A total of 21 adverse events of grade 3 or higher were noted. They included cytomegalovirus reactivation or infection in six patients; neutropenia in four patients; persistent fever in two patients; and pleural effusion, pulmonary hypertension, and a neurologic disorder in one patient each.

Of the 24 patients who received a stem-cell allograft, two died, but only one death was related to transplant (4%).

The very low nonrelapse mortality among patients who underwent transplant during remission is “remarkable,” Dr. Hoelzer wrote. It suggests that toxicity from induction chemotherapy puts the patient at risk for toxic effects and death from subsequent stem-cell transplant – “a consequence that is avoided with targeted therapy.”
 

Unanswered questions

“Will the excellent outcomes be preserved with longer follow-up? The answer is probably yes, given that the majority of relapses in ALL occur within the first 1.5 to 2.0 years after the initiation of treatment,” Dr. Hoelzer wrote.

He said other outstanding questions include whether long-term outcomes will differ between patients who undergo transplant and those who do not; whether ABL1 mutations emerge; whether minimal residual disease recurs with longer follow-up; and whether this treatment approach can be used for patients with other subtypes of ALL, such as Ph-negative, B-lineage ALL, or even T-cell ALL.

“If these promising trial results hold, chemotherapy-free induction without the immediate and long-term toxic effects of intensive chemotherapy regimens could also be used in adolescents and, finally, in children. These questions will need to be addressed with longer follow-up and large, prospective trials,” Dr. Hoelzer concluded.

The study was supported by grants from the Italian Association for Cancer Research and Sapienza University of Rome.

Key clinical point: Several long noncoding RNAs (lncRNAs) were strongly associated with disease pathogenesis and prognosis in myelodysplastic syndrome (MDS) patients.

Major finding: Based on genome-wide profiling, lncRNA gene networks with expression of H19, WT1-AS, TCL6, and LEF1-AS1 were associated with higher-risk MDS; of these, H19 also showed promise as a therapeutic target because of its strong predictive value for lower complete remission rate of induction therapy in AML in the presence of H19 overexpression. 

Study details: The data come from a study of genetic profiling including 54 patients with MDS, 14 patients with acute myeloid leukemia with myelodysplasia-related changes (AML-MRC), and 9 healthy donors.

Disclosures: The study was supported by the Project for Conceptual Development of Research Organization from the Ministry of Health of the Czech Republic. The researchers had no financial conflicts to disclose.

A commonly used newborn hearing test shows promise in the early detection of autism spectrum disorder (ASD), new research shows.  

Results from one of the largest studies of its kind show the auditory brainstem response (ABR) test, which is carried out on most newborns, represents “a huge untapped potential” to detect autism, lead author Oren Miron, research associate, department of biomedical informatics, Harvard Medical School, Boston, and a PhD candidate at Ben Gurion University in Beersheba, Israel, said in an interview.

“The findings further reinforce our understanding that autism, in many cases, has a sensorial and auditory aspect to it,” said Mr. Miron, adding that an adverse response to sound is one of the earliest behavioral signs of autism.

The research was published online Oct. 31 in Autism Research.
 

Early intervention critical

Autism spectrum disorder (ASD), which involves problems in social communication and interaction, affects an estimated 1 in 59 children. Early identification and intervention are critical for improving outcomes and decreasing the economic burden associated with ASD.

The ABR test, which is used for Universal Newborn Hearing Screening (UNHS), uses surface electrodes to measure auditory nerve and brainstem responses to sound.

Previous studies identified abnormal ABR amplitude in children with ASD. However, it’s unclear whether healthy newborns who later develop autism also show ABR differences vs those who don’t develop the disorder.

Researchers used UNHS data, which allowed them to examine a larger, younger, and healthier sample compared with previous studies. The study included 321 newborns later diagnosed with ASD and 138,844 controls without a subsequent ASD diagnosis.

The mean ABR testing age was 1.76 days for newborns later diagnosed with ASD and 1.86 for those in the non-ASD group.

The ASD group was 77% male and the non-ASD group was 51% male. The rate of neonatal intensive care unit admission was 8% in the ASD group and 10% in the non-ASD group.

The hearing test involves placing an earpiece in the baby’s ear and delivering a click sound at 35 dB above normal hearing level (nHL) at a rate of 77 clicks per second in the right ear and 79 clicks per second in the left ear.
 

Brainstem abnormalities?

The clicks create electrical activity, which is recorded by a surface electrode and used to extract the ABR waveform. When a sound reaches the brain stem, it creates five consecutive waveforms – waves I, II, III, IV, and V.

Previous studies focused on wave V, which is easiest to detect. The current study used low intensity sound that resulted in a weaker signal.

To overcome this low intensity issue, researchers focused on the negative drop (latency) after the wave V (Vn), which is easier to detect, and on the ABR phase, or entire waveform. They illustrated the differences between the ASD and non-ASD groups in a series of graphs.

Results showed that the ABR phase in the right ear was significantly prolonged in the ASD vs non-ASD group (P < .001). ABR phase in the left ear was also significantly prolonged in the ASD group (P = .021)

Vn latency in the right ear was significantly prolonged in the ASD group compared with the non-ASD group (P = .048); however, this was not the case in the left ear.

The prolongation could mean that the V-negative wave might appear after 8 ms in normally developing children compared with 8.5 or 9 ms in children with autism, said Mr. Miron.

The new study is the first to show V-negative and phase abnormalities are associated with ASD, the authors note. The brainstem prolongation could be due to anatomical abnormalities in the brainstem in individuals with ASD, the researchers added.
 

Present before birth?

The presence of ABR biomarkers of ASD in the first weeks after birth suggests the disorder is likely present before birth in a large group of these individuals, the researchers note.

It’s possible the ABR test could be modified to use lower intensities not only to detect hearing impairment but autism risk, said Mr. Miron. “The test has been optimized to detect hearing impairment, and it does so brilliantly and helps thousands of children. We want to do the same kind of optimization for autism.”

This could lead to earlier behavioral diagnoses, which, in turn, could lead to earlier treatment and better outcomes for children with ASD, said Mr. Miron.

At this time, the level of prolongation to detect ASD is unclear. “I would think a lot of people would want to make it one standard deviation, but it depends on a lot of factors, including for example, whether a baby is preterm,” said Mr. Miron.

More research and better accuracy and specificity are needed before the newborn hearing test is clinically useful.

He noted that the hearing test is only one marker of autism and that it could potentially be combined with other behavioral signs and genetic markers to facilitate earlier diagnosis and treatment and improve outcomes for patients with ASD.

Future research by his group will investigate whether the degree of auditory prolongation relates to autism severity. They also plan to research ASD subgroups including children with comorbid epilepsy.
 

Terrific, clever research

Jeremy Veenstra-VanderWeele, MD, professor, child and adolescent psychiatry, Columbia University, New York, said in an interview that the study is “terrific” and a “clever use” of an existing dataset.

“They showed a difference between a large group of kids with autism and a large group of kids without.”

However, he added, more research is needed before the test can be used as an autism screening tool.

“In order for this to be a screening test that could be broadly applied you would need to identify a cutoff where you’d think a child was at risk for autism, and if you look at the graphs in the article, there are no clear cutoffs,” said Dr. Veenstra-VanderWeele.

To turn this into a useful test, “you would have to establish sensitivity and specificity, you would have to look not just at the comparison of kids with autism and kids without but apply it in a predictive way in a second population.”

The study authors and Dr. Veenstra-VanderWeele have reported no relevant financial relationships. Veenstra-VanderWeele is an associate editor at Autism Research, which published the article, but he did not handle or view it before being interviewed.
