ATLANTA—Initial results of the phase 2 HOVON-126 trial in newly diagnosed multiple myeloma (MM) patients have highlighted the need for an induction strategy in elderly and frail patients.

The trial showed high overall response rates (ORRs) after induction with ixazomib, thalidomide, and low-dose dexamethasone.

However, 62% of patients older than 75 and 60% of frail patients discontinued therapy prior to starting maintenance.

HOVON-126 was designed to determine the ORR of induction therapy with ixazomib, thalidomide, and dexamethasone but also compare progression-free survival in patients who received ixazomib maintenance and those who received placebo.

Sonja Zweegman, MD, of VUmc in Amsterdam, The Netherlands, presented induction results from HOVON-126 at the 2017 ASH Annual Meeting (abstract 433).

The study was supported by Takeda and the Dutch Cancer Society. Dr Zweegman disclosed research funding from, and advisory board participation for, Takeda.

Study design

Investigators enrolled patients with previously untreated, symptomatic MM who were not eligible for stem cell transplant. Patients had to have measurable disease and a WHO performance status of 0 to 3 for patients younger than 75 and 0 to 2 for patients 75 or older.

Patients were not eligible if they had grade 3 neuropathy or grade 2 with pain. They were also ineligible if their creatinine clearance was less than 30 mL/minute.

All patients received ixazomib at 4 mg on days 1, 8, and 15; thalidomide at 100 mg on days 1 to 28; and dexamethasone at 40 mg on days 1, 8, 15, and 22 for nine 28-day cycles.

They could then be randomized to ixazomib maintenance (on the aforementioned schedule) or placebo for 28-day cycles until progression.

Investigators performed subgroup analyses based on cytogenetic risk and frailty.

They defined frailty according to the modified IMWG frailty index, which takes into account age, the Charlson Comorbidity Index, and the WHO performance scale as a proxy for Activities of Daily Living.

They defined high-risk cytogenetics as del17p, t(4;14), or t(14;16).

Investigators planned to enroll 142 patients and expected 94 patients to be randomized.

Patient demographics

The first 120 patients enrolled had a median age of 74 (range, 64–90). Thirty percent (n=38) were older than 75, and 8% (n=10) were older than 80.

More than two-thirds had an ISS score of I or II, and three-quarters had a WHO performance status of 0 or 1. Twenty-four percent had a performance status of 2, and 1% had a performance status of 3.

Eighty percent had lytic bone disease.

One hundred thirteen patients (94%) had FISH analysis performed. Of those, 10% had del17p, 7% had t(4;14), and 1% had t(14;16).

Eighty-one percent of patients fell into the standard-risk category and 19% into the high-risk category.

Almost half of patients (47%) were considered frail, 28% unfit, 21% fit, and 4% unknown.

Response

The ORR for induction was 81%. Ten percent of patients achieved a complete response (CR), 34% had a very good partial response (VGPR), and 37% had a partial response (PR).

The median time to response was 1.1 months, and the median time to maximum response was 4.7 months.

The response rate was independent of cytogenetic risk. Standard-risk patients achieved an ORR of 84%, a VGPR rate of 48%, and a CR rate of 10%. High-risk patients had an ORR of 79%, VGPR of 42%, and CR of 11%.

The response rate was also independent of frailty. Fit patients had an ORR of 88%, unfit patients 85%, and frail patients 75%. The VGPR rate was 36% for fit, 53% for unfit, and 43% for frail patients. The CR rate was 16% for fit, 9% for unfit, and 9% for frail patients.

Safety

“Grade 3 and 4 toxicities were found to be limited, with mainly infections, [gastrointestinal], and skin toxicity,” Dr Zweegman noted. “There was also a very low incidence of neuropathy, with only 3% grade 3 neuropathy and no grade 4 neuropathy.”

Grade 3 adverse events (AEs) occurred in 50% of patients and grade 4 in 11%.

Hematologic AEs of grade 3 and 4, respectively, included anemia (5%, 1%), thrombocytopenia (3%, 1%), and neutropenia (1%, 0).

Nonhematologic AEs of grade 3 and 4, respectively, included infections (12%, 3%), neuropathy (3%, 0), cardiac events (7%, 3%), gastrointestinal events (8%, 0), skin AEs (10%, 0), and venous thromboembolism (0, 2%).

The incidence of severe neuropathy was low. Fifty-eight percent of patients had grade 0 neuropathy, 24% grade 1, 14% grade 2, 3% grade 3, and no grade 4.

Discontinuation

 Fifty-four patients (45%) discontinued therapy. The reasons for discontinuation were:

• Progressive disease, 13%
• Toxicity, 15%
• Death, 4%
• Noncompliance, 8%
• Not eligible for randomization, 0.8%
• Other, 4%.

“And when looking in detail into the toxicity, it was shown that it was mainly asthenia and neuropathy being judged by the treating physicians as caused by thalidomide,” Dr Zweegman explained.

Investigators also evaluated discontinuation according to age and found that 35% of patients 75 or younger discontinued therapy, compared with 62% of those older than 75.

However, there was no significant difference in discontinuation rate during the first 6 cycles. Seventy-seven percent of the younger patients and 69% of the older group completed 6 cycles.

Older patients who discontinued early had rates of progressive disease and toxicity comparable to the younger patients, but “there was a difference in early mortality,” Dr Zweegman added.

Nine percent of older patients discontinued before maintenance due to early mortality, compared with 1% of younger patients. And mortality in the older group was mainly due to infections and 1 cardiac arrest.

“So I think that highlights the need for antibiotic prophylaxis, which was not mandatory in this study,” Dr Zweegman said.

And finally, the investigators evaluated discontinuation according to frailty. Twenty-four percent of fit patients discontinued prior to maintenance, 32% of unfit, and 60% of frail.

Again, investigators found no significant difference in discontinuation rate during the first 6 cycles of induction. Eighty percent of fit patients completed 6 cycles, as did 79% of unfit patients and 70% of frail patients.

Despite the feasibility of the treatment and an ORR of 81%, the investigators say novel approaches are needed for frail patients and those older than 75.

“One possibility is to limit the duration of induction therapy . . . ,” Dr Zweegman said. “That would allow the start of long-term administration of maintenance treatment.”

The investigators also suggest evaluating less toxic combinations, such as ixazomib and daratumumab with lower doses of dexamethasone, the combination used in the HOVON-143 study.

Ixazomib is approved by the US Food and Drug Administration, Health Canada, and conditionally approved by the European Commission for use in combination with lenalidomide and dexamethasone to treat MM patients who have received at least 1 prior therapy.

Chemotherapy for acute myeloid leukemia (AML) might be improved by the addition of deferoxamine, according to preclinical research published in Cell Stem Cell.

Researchers found that, when certain areas of the bone marrow are overtaken by AML cells, hematopoietic stem cells (HSCs) are lost, and the delivery of chemotherapy may be compromised.

However, the team also discovered that deferoxamine, a drug already approved to treat iron overload, can protect these areas of the bone marrow, allowing HSCs to survive and improving the efficacy of chemotherapy.

“Since the drug is already approved for human use for a different condition, we already know that it is safe,” said study author Cristina Lo Celso, PhD, of Imperial College London in the UK.

“We still need to test it in the context of leukemia and chemotherapy, but, because it is already in use, we can progress to clinical trials much quicker than we could with a brand-new drug.”

For the current study, Dr Lo Celso and her colleagues used intravital microscopy to study AML cells, healthy hematopoietic cells, and the bone marrow microenvironment in mice.

The researchers found the endosteal microenvironment was hit particularly hard by AML. Specifically, AML progression led to endosteal remodeling, with AML cells degrading endosteal endothelium, stromal cells, and osteoblastic cells.

This remodeling resulted in the loss of nonleukemic HSCs, which hindered hematopoiesis. However, preserving endosteal vessels prevented the loss of HSCs.

Previous research had shown that deferoxamine could induce endosteal vessel expansion through enhancement of hypoxia-inducible factor 1a stability and activity. So the researchers administered deferoxamine to mice with AML.

The drug had a protective effect on endosteal vessels, which were able to support healthy HSCs and improve HSC homing.

The researchers also found that enhanced endosteal vessels improved the efficacy of chemotherapy (cytarabine and doxorubicin) in mice with AML.

The team compared Fbxw7^iΔEC-mutant mice, in which the administration of tamoxifen increases the number of endosteal vessels and arterioles, to control mice. Both sets of mice had AML.

After confirming the mutant mice had increased numbers of endosteal vessels, the researchers treated the mutant mice and controls with cytarabine and doxorubicin.

Both sets of mice had significant chemotherapy-induced damage to the bone marrow vasculature, including endosteal vessels.

However, after treatment, the Fbxw7^iΔEC-mutant mice had lower numbers of surviving AML cells in the bone marrow, delayed relapse, and longer survival than control mice.

The researchers therefore concluded that rescuing endosteal vessels before starting chemotherapy can improve the efficacy of treatment in AML.

“Our work suggests that therapies targeting these blood vessels may improve existing therapeutic regimens for AML and perhaps other leukemias too,” said study author Delfim Duarte, MD, of Imperial College London.

Based on this work, the researchers are hoping to start trials of deferoxamine in patients with AML.

Researchers have gained new insight into hearing loss caused by cisplatin.

By measuring and mapping cisplatin retention in mouse and human inner ear tissues, the researchers found that cisplatin builds up in the inner ear and can remain there for years.

The team also found that a region in the inner ear called the stria vascularis could be targeted to prevent hearing loss resulting from cisplatin.

Lisa L. Cunningham, PhD, of the National Institute on Deafness and other Communications Disorders (NIDCD) in Bethesda, Maryland, and her colleagues reported these findings in Nature Communications.

The researchers noted that cisplatin can cause permanent hearing loss in 40% to 80% of treated patients. The team’s new findings help explain why.

The researchers found that, in most areas of the body, cisplatin is eliminated within days or weeks of treatment, but, in the inner ear, the drug remains much longer.

The team developed a mouse model that represents cisplatin-induced hearing loss seen in human patients.

By looking at inner ear tissue of mice after the first, second, and third cisplatin treatment, the researchers saw that cisplatin remained in the mouse inner ear much longer than in most other body tissues, and the drug builds up with each successive treatment.

The team also studied inner ear tissue donated by deceased adults who had been treated with cisplatin and found the drug is retained in the inner ear months or years after treatment.

When the researchers examined inner ear tissue from a child, they found cisplatin buildup that was even higher than that seen in adults.

Taken together, these results suggest the inner ear readily takes up cisplatin but has limited ability to remove the drug.

In mice and human tissues, the researchers saw the highest buildup of cisplatin in a part of the inner ear called the stria vascularis, which helps maintain the positive electrical charge in inner ear fluid that certain cells need to detect sound.

The team found the accumulation of cisplatin in the stria vascularis contributed to cisplatin-related hearing loss.

“Our findings suggest that if we can prevent cisplatin from entering the stria vascularis in the inner ear during treatment, we may be able to protect cancer patients from developing cisplatin-induced hearing loss,” Dr Cunningham said.

By measuring and mapping cisplatin retention in mouse and human inner ear tissues, the researchers found that cisplatin builds up in the inner ear and can remain there for years.

The team also found that a region in the inner ear called the stria vascularis could be targeted to prevent hearing loss resulting from cisplatin.

Lisa L. Cunningham, PhD, of the National Institute on Deafness and other Communications Disorders (NIDCD) in Bethesda, Maryland, and her colleagues reported these findings in Nature Communications.

The researchers noted that cisplatin can cause permanent hearing loss in 40% to 80% of treated patients. The team’s new findings help explain why.

The researchers found that, in most areas of the body, cisplatin is eliminated within days or weeks of treatment, but, in the inner ear, the drug remains much longer.

The team developed a mouse model that represents cisplatin-induced hearing loss seen in human patients.

By looking at inner ear tissue of mice after the first, second, and third cisplatin treatment, the researchers saw that cisplatin remained in the mouse inner ear much longer than in most other body tissues, and the drug builds up with each successive treatment.

The team also studied inner ear tissue donated by deceased adults who had been treated with cisplatin and found the drug is retained in the inner ear months or years after treatment.

When the researchers examined inner ear tissue from a child, they found cisplatin buildup that was even higher than that seen in adults.

Taken together, these results suggest the inner ear readily takes up cisplatin but has limited ability to remove the drug.

In mice and human tissues, the researchers saw the highest buildup of cisplatin in a part of the inner ear called the stria vascularis, which helps maintain the positive electrical charge in inner ear fluid that certain cells need to detect sound.

The team found the accumulation of cisplatin in the stria vascularis contributed to cisplatin-related hearing loss.

“Our findings suggest that if we can prevent cisplatin from entering the stria vascularis in the inner ear during treatment, we may be able to protect cancer patients from developing cisplatin-induced hearing loss,” Dr Cunningham said.

Clinical question: How have national and county-level opioid prescribing practices changed from the years 2006 to 2015?

Background: The opioid epidemic is currently at the forefront of public health crises, with more than 15,000 deaths caused by prescription opioid overdoses in 2015 alone and an estimated 2 million people with an opioid use disorder associated with prescription opioids. The opioid epidemic also has a significant financial burden with the cost of opioid overdose, abuse, and dependence totaling $78.5 billion/year in the United States. As the utilization of opioids to treat noncancer pain quadrupled during 1999-2010, so did the prevalence of opioid misuse disorder and overdose deaths from prescription opioids. This study reviewed prescribing practices at the national and county level during 2006-2015 in hopes of understanding how this affected the opioid crisis.

The common diuretic hydrochlorothiazide is linked to a dose-dependent increased risk of nonmelanoma skin cancer, in particular, squamous cell carcinoma, a case-controlled registry study showed.

This nationwide, case-matched control study examined patients’ cumulative hydrochlorothiazide use between 1995 and 2012 and found a clear dose-response patterns for both basal cell carcinoma (BCC) and squamous cell carcinoma (SCC), with a more than sevenfold increased risk of SCC for a cumulative use of greater than or equal to 200,000 mg of hydrochlorothiazide (HCTZ).

“Assuming causality, the present results suggest that 1 in 10 SCC cases diagnosed during the study period can be attributed to HCTZ use,” wrote the study authors, who were led by Sidsel Arnspang, MD, of the department of neurology at Odense (Denmark) University Hospital, which is affiliated with the University of Southern Denmark.

The authors noted that they previously had reported a sevenfold increased risk of lip squamous cell carcinoma with hydrochlorothiazide. Furthermore, the International Agency for Research on Cancer recently classified the diuretic and antihypertensive as “possibly carcinogenic to humans.”

“As HCTZ is among the most widely used drugs in the U.S. and Western Europe, a carcinogenic effect of HCTZ would have a considerable impact on public health,” they wrote in their paper, published in the Journal of American Academy of Dermatology.

According to the study authors, the few studies that have investigated a potential link between thiazide use and nonmelanoma skin cancer (NMSC) have reported inconsistent results.

They speculated that this could be because HCTZ often is prescribed in combination with other diuretics, and there may have been difficulties with disentangling its effect from those of the other drugs.

Using data from five nationwide data sources, the research team compared HCTZ use among people diagnosed with SCC or BCC of the skin to use among a matched control group without such cancers. People were excluded from the analysis if they had SCC of the lip because they had been evaluated in the research team’s previous study.

Esketamine – the S-enantiomer of the anesthetic ketamine – continues to look promising as an adjunctive treatment for refractory depression, phase 2 results of a four-phase multicenter trial suggested.

“We observed a significant and clinically meaningful treatment effect (vs. placebo) with 28-mg, 56-mg, and 84-mg doses of esketamine,” reported Ella J. Daly, MD, of Janssen, and her associates. The results were apparent 1 week after treatment, and they persisted over the follow-up phase, which lasted 8 weeks.

“Results support further investigation of intranasal efficacy of esketamine for the management of [treatment-resistant depression] in larger trials,” Dr. Daly and her associates wrote in JAMA Psychiatry (2017 Dec 27. doi: 10.1001/jamapsychiatry.2017.3739).

In the study, patients aged 20-64 years with a diagnosis of major depressive disorder were recruited from several outpatient referral centers. All of the participants had treatment-resistant depression, defined by the study as an inadequate response despite the use of two or more antidepressants. Overall, 67 patients were randomized to receive one of the three doses of intranasal esketamine or a placebo nasal spray. In addition, participants continued to take oral antidepressants during the study period. People with a history of psychotic symptoms, use of substances such as alcohol and cannabis, or significant medical comorbidities were excluded.

Among participants in the treatment groups, the mean total score changes on the Montgomery-Åsberg Depression Rating Scale (MADRS) surpassed the MADRS score changes among those on placebo. Specifically, the mean MADRS score change for those on the 28-mg dose was –4.2 (P = 0.2), on the 56-mg dose was –6.3 (P = .001), and on the 84-mg dose was –9 (P less than .001).

The most common side effects among participants treated with esketamine were dizziness, headache, and dissociative symptoms. However, most adverse events were transient and “either mild or moderate in severity,” the investigators reported.

Dr. Daly and her associates cited several limitations, including the small sample size and the study’s exclusion criteria. Despite those limitations, Dr. Daly and her associates said, the results support further investigation of intranasal esketamine for treatment-resistant depression. They said a phase 3 study aimed at evaluating the frequency needed for dosing and duration of effect is underway.

Janssen funded the study. Dr. Daly and several of the other investigators are Janssen employees.

ATLANTA – Recent improvements in multiple myeloma survival have left young Hispanic patients behind, the results of a national longitudinal study suggest.

Among U.S. adults diagnosed with multiple myeloma by age 40 years, 5-year and 10-year survival improved significantly (P less than .0001) for non-Hispanic blacks and whites, but not for Hispanics (5-year survival, P = .08; 10-year survival, P = .13), Abdel-Ghani Azzouqa, MD, and colleagues reported in a poster at the annual meeting of the American Society of Hematology.

The Food and Drug Administration has approved nivolumab for the adjuvant treatment of patients with melanoma with involvement of lymph nodes or in patients with metastatic disease who have undergone complete resection.

Nivolumab was previously approved for the treatment of patients with unresectable or metastatic melanoma, the FDA said in a press statement.

Approval was based on results from the CHECKMATE-238 trial, where 906 patients with completely resected stage IIIB/C or stage IV melanoma received either nivolumab or ipilimumab for up to 1 year. Recurrence-free survival was superior in patients who received nivolumab, with 34% of patients in the nivolumab group experiencing recurrence/death, compared to 45.5% in the ipilimumab group.
