The Food and Drug Administration on Nov. 8 approved the use of letermovir (Prevymis) tablets and injections for the prevention of cytomegalovirus (CMV) infection and disease in adults exposed to the virus who have received an allogeneic hematopoietic stem cell transplant (HSCT). This is the first drug to be approved for this purpose. It had previously been granted Breakthrough Therapy and Orphan Drug designation.

CMV infection is a major risk for patients undergoing HSCT, because an estimated 65%-80% of these patients already have been exposed to the virus.

SAN DIEGO – The intravenous echinocandin anidulafungin effectively treated invasive candidiasis in a single-arm, multicenter, open-label trial of 47 children aged 2-17 years.

The overall global response rate of 72% resembled that from the prior adult registry study (76%), Emmanuel Roilides, MD, PhD, and his associates reported in a poster presented at an annual scientific meeting on infectious diseases.

At 6-week follow-up, two patients (4%) had relapsed, both with Candida parapsilosis, which was more resistant to treatment with anidulafungin (Eraxis) than other Candida species, the researchers reported. Treating the children with 3.0 mg/kg anidulafungin on day 1, followed by 1.5 mg/kg every 24 hours, yielded similar pharmacokinetics as the 200/100 mg regimen used in adults. The most common treatment-emergent adverse effects included diarrhea (23%), vomiting (23%), and fever (19%), which also reflected findings in adults, the investigators said. Five patients (10%) developed at least one severe treatment-emergent adverse event, including neutropenia, gastrointestinal hemorrhage, increased hepatic transaminases, hyponatremia, and myalgia. The study (NCT00761267) is ongoing and continues to recruit patients in 11 states in the United States and nine other countries, with final top-line results expected in 2019.

CHICAGO – Tocilizumab may be a therapeutic option for steroid-refractory immune-related adverse events that are secondary to PD-1 blockade, according to findings from a review of patients treated with nivolumab for various malignancies.

Of 87 patients who were treated with the PD-1 inhibitor between April 2015 and October 2016, 34 received tocilizumab for high-grade immune-related adverse events (irAEs) that were refractory to corticosteroids. Of those, 27 experienced clinical improvement, which was defined as documentation of symptom resolution or hospital discharge within 7 days, Aparna Hegde, MD, of East Carolina University, Greenville, N.C., reported at the Chicago Multidisciplinary Symposium in Thoracic Oncology.

The median time to discharge was 4 days, and no adverse effect on median overall survival was seen between those who received tocilizumab and those who did not (6.1 vs, 6.7 months, respectively), Dr. Hegde said.

There was, however, a trend toward inferior overall survival in patients who required more than one dose of tocilizumab, but the difference was not statistically significant (hazard ratio, 1.72), she noted.

“Immune checkpoint inhibitors are associated with an unprecedented clinical benefit in patients with lung cancer. However, they are also associated with a unique spectrum of immune-mediated adverse events. While the standard of care for initial management of these adverse events is corticosteroids, the management of steroid-refractory events is poorly defined,” she said, adding that data from randomized trials on which consensus guidelines could be based are lacking.

At East Carolina University, a significant proportion of patients treated with PD-1 inhibitors were presenting with systemic inflammatory response syndrome (SIRS)-like symptoms and immune-related organ toxicities similar to what has been described in cytokine release syndrome, Dr. Hegde said.

Such symptoms have also been reported with other types of immune therapy, such as CAR T-cell therapy and bispecific T-cell receptor–engaging antibodies in hematologic malignancies, she noted.

“In our experience, when we treated these patients with tocilizumab, which is an [anti-interleukin-6] receptor monoclonal antibody, we saw dramatic and rapid responses, not only in the SIRS symptoms, but also in other immune-related organ toxicities. Therefore, we adopted the use of tocilizumab as our standard treatment for high-grade immune-related adverse events,” she said, explaining that it has been well documented that interleukin (IL)-6 levels increase during cytokine release syndrome and are mediators of inflammation, suggesting that blocking IL-6 may treat irAEs without compromising the efficacy of immune therapy.

The current study was undertaken to look more closely at the responses to tocilizumab and to assess overall survival in those who received tocilizumab.

Study participants were being prospectively followed as part of another ongoing study looking at the relationship between systemic inflammation and cancer-related symptom burden. Most (77) were being treated for lung cancer and 10 had other types of malignancy. They received nivolumab at a dose of 3 mg/kg (or a flat dose of 240 mg after September 2016) every 2 weeks, and received tocilizumab at a dose of 4 mg/kg given over 1 hour. Those with grade 3 or 4 irAEs also received supportive care and corticosteroids. Median follow-up was 10.6 months.

C-reactive protein (CRP), a reliable surrogate marker of IL-6, was drawn at the first nivolumab infusion and before each subsequent infusion as part of the study in which the patients were enrolled, and for the current analysis was measured in relation to irAEs.

Significant reductions were seen in CRP levels after tocilizumab treatment; similar responses have been described in cytokine release syndrome, Dr. Hegde noted.

“Tocilizumab is a therapeutic option for management of immune-related adverse events in patients who are already on corticosteroids. CRP may be of clinical utility in detecting immune-related adverse events as well as monitoring the response to tocilizumab,” she said, adding that the current analysis is limited by the small patient number, single-center setting, use of tocilizumab outside of a clinical trial setting, and short follow-up.

Therefore, the findings require confirmation in multicenter randomized trials to determine “the definitive utility of tocilizumab, as well as CRP as an accompanying biomarker in the management of high-grade steroid refractory immune-related adverse events.”

Heather Wakelee, MD, an invited discussant at the symposium, commended Dr. Hegde and her colleagues for “coming up with a novel idea about how to treat [irAEs],” but also stressed the need for further study.

“This is a novel agent that has the potential ability to manage toxicity, and that’s important, because when you get beyond the steroids that we use as a first-line approach ... there’s not a whole lot else. We definitely have a clear unmet need,” said Dr. Wakelee of Stanford (Calif.) University.

However, she stressed that the approach must be evaluated in multicenter randomized trials “before we can be widely discussing this as a good thing to be doing.”

Dr. Hegde reported having no disclosures. Dr. Wakelee has been the institutional principal investigator for studies of nivolumab, tocilizumab, and other agents. She has consulted for Peregrine, ACEA, Pfizer, Helsinn, Genentech/Roche, Clovis, and Lilly, and received research/grant support from Clovis, Exelixis, AstraZeneca/Medimmune, Genentech/Roche, BMS, Gilead, Novartis, Xcovery, Pfizer, Celgene, Gilead, Pharmacyclics, and Lilly.

One-size-fits-all T cells designed to recognize and mount an immune response against five common viral pathogens may help to reduce the incidence of severe viral infections and treatment-related deaths in patients who have undergone hematopoietic stem cell transplants (HSCT), investigators reported.

Among 37 evaluable patients who had undergone an allogeneic HSCT, a single infusion of banked virus-specific T cells (VSTs) directed against adenovirus, BK virus, cytomegalovirus (CMV), Epstein-Barr virus (EBV), and human herpesvirus 6 (HHV-6) was associated with a 92% cumulative complete or partial response rate, reported Ifigeneia Tzannou, MD, and her colleagues from Baylor College of Medicine in Houston.

“Although a randomized trial will be required to definitively assess the value of banked VSTs, this study strongly suggests that off-the-shelf, multiple-virus–directed VSTs are a safe and effective broad-spectrum approach to treat severe viral infections after HSCT. These VSTs can be rapidly and cost effectively produced in scalable quantities with excellent long-term stability, which facilitates the broad implementation of this therapy,” they wrote in the Journal of Clinical Oncology (2017 Aug 7. doi: 10.1200/JCO.2017.73.0655).

Although adoptive transfer of VSTs derived from donor stem cells has been shown to protect patients against viral pathogens, the technique is hampered by costs, complexity, the time-consuming manufacturing process, and the need for seropositive donors, Dr. Tzannou and her colleagues pointed out.

“One way to overcome these limitations and to supply antiviral protection to recipients of allogeneic HSCT would be to prepare and cryopreserve banks of VST lines from healthy seropositive donors, which would be available for immediate use as an off-the-shelf product,” they wrote.

They tested this concept in a phase 2 clinical trial in 38 patients with a total of 45 infections.

A single infusion was associated with cumulative complete and partial responses rates of 71% in 7 patients with adenoviral infections, 100% in 16 patients with BK virus infections, 94% in 17 patients with CMV infections, 100% for 2 patients with EBV infections, and 67% for 3 patients with HHV-6 infections.

Seven of the 38 patients received VSTs for two viral infections, and all patients had viral control after a single infusion. All cases of CMV, adenovirus, and EBV infections were cleared from serum. One patient with HHV-6 encephalitis had complete resolution of encephalitis after one infusion and resolution of hemorrhagic cystitis after a second infusion; 14 patients with BK virus–associated hemorrhagic cystitis had clinical improvement or resolution of disease.

The infusions were delivered safely. After infusion, one patient developed recurrent grade 3 gastrointestinal graft versus host disease (GVHD) after a rapid corticosteroid taper, three patients had recurrent grade 1 or 2 skin GVHD, and two patients had de novo skin GVHD. Of the five cases of skin GVHD, four resolved with the administration of topical treatments and one with the reinstitution of corticosteroids after a taper.

“More widespread and earlier use of this modality could minimize both drug-related and virus-associated complications and thereby decrease treatment-related mortality in recipients of allogeneic HSCT,” the investigators wrote.

The study was supported by the National Heart, Lung, and Blood Institute; Conquer Cancer Foundation; and Dan L. Duncan Comprehensive Cancer Center. Dr. Tzannou disclosed having a consulting or advisory role with ViraCyte, and several coauthors reported financial ties with various companies.

Administration of azithromycin beginning at the time of conditioning in patients undergoing allogeneic hematopoietic stem cell transplant resulted in worse airflow decline–free survival than did placebo, according to findings from the randomized ALLOZITHRO trial.

The 2-year airflow decline–free survival rate was 32.8% in 243 patients who received 250 mg of azithromycin for 2 years, compared with 41.3% in 237 who received placebo (hazard ratio, 1.3), Anne Bergeron, MD, of Hopital Saint-Louis, Paris, and her colleagues reported in the Aug. 8 issue of JAMA.

Further, of 22 patients who experienced bronchiolitis obliterans syndrome, 15 were in the azithromycin group, compared with 7 in the placebo group, and 2-year mortality was increased in the azithromycin group (56.6% vs. 70.1%; hazard ratio, 1.5) the investigators noted (JAMA. 2017 Aug 8;318[6]:557-66. doi: 10.1001/jama.2017.9938).

A post hoc analysis showed that the 2-year cumulative incidence of hematological relapse was 33.5% with azithromycin vs. 22.3% with placebo; the trial was terminated early because of this unexpected finding.

Although prior studies have suggested that azithromycin may reduce the incidence of post–lung transplant bronchiolitis obliterans syndrome, which has been shown to increase morbidity and mortality after allogeneic HSCT, the findings of this parallel-group trial conducted in 19 French transplant centers between February 2014 and August 2015 showed a decrease in survival and an increase in hematological relapse at 2 years with azithromycin vs. placebo. The findings, however, are limited by several factors – including the trial’s early termination – and require further study, particularly of the potential for harm related to relapse, the investigators concluded.

The ALLOZITHRO trial (NCT01959100) was funded by the French Cancer Institute, Oxygene, and SFGM-TC Capucine. Dr. Bergeron reported receiving unrestricted research grant funding for the trial from the French Ministry of Health, SFGM-TC Capucine association, and SOS Oxygene; receiving speaker fees from Merck, Gilead, and Pfizer; and serving on the advisory board of Merck.

Administration of azithromycin beginning at the time of conditioning in patients undergoing allogeneic hematopoietic stem cell transplant resulted in worse airflow decline–free survival than did placebo, according to findings from the randomized ALLOZITHRO trial.

The 2-year airflow decline–free survival rate was 32.8% in 243 patients who received 250 mg of azithromycin for 2 years, compared with 41.3% in 237 who received placebo (hazard ratio, 1.3), Anne Bergeron, MD, of Hopital Saint-Louis, Paris, and her colleagues reported in the Aug. 8 issue of JAMA.

Further, of 22 patients who experienced bronchiolitis obliterans syndrome, 15 were in the azithromycin group, compared with 7 in the placebo group, and 2-year mortality was increased in the azithromycin group (56.6% vs. 70.1%; hazard ratio, 1.5) the investigators noted (JAMA. 2017 Aug 8;318[6]:557-66. doi: 10.1001/jama.2017.9938).

CHICAGO – Late dermatologic manifestations in children who have received hematopoietic stem cell transplants may be more common than previously thought, according to results of a new study.

Johanna Song, MD, and her collaborators reported that, in their prospective pediatric study, 25% of patients had permanent alopecia and 16% had psoriasis, noting that late nonmalignant skin effects of hematopoietic stem cell transplantation (HSCT) have been studied primarily retrospectively, and in adults. Vitiligo and nail changes were also seen.

In a poster presentation at the World Congress of Dermatology, Dr. Song and her colleagues noted that these figures are higher than the previously reported pediatric rates of 1.7% for vitiligo and 15.6% for permanent alopecia. “Early recognition of these late effects can facilitate prompt and appropriate treatment, if desired,” they said.

The single-center, cross-sectional cohort study tracked pediatric patients over an 18-month period and included patients who were at least 1 year post allogeneic HSCT and had not relapsed. Patients who were not English speaking were excluded.

The median age of the 85 patients enrolled in the study was 13.8 years, and participants were a median of 3.6 years post transplant at the time of enrollment. The study’s analysis attempted to determine which patient, transplant, and disease factors might be associated with the late nonmalignant skin changes, according to Dr. Song, a resident dermatologist at Harvard University, Boston, and her colleagues.

Most – 52– of the patients (61.2%) had hematologic malignancies; 12 patients (14.1%) received their transplant for bone marrow failure, and 11 patients (12.5%) had immunodeficiency. Three patients (3.5%) received HSCT for other malignancies, and seven (8.2%) for nonmalignant diseases.

Diffuse hair thinning was seen in 13 (62%) of the 21 patients who had alopecia, while 11 (52%) of the patients with alopecia had an androgenetic hair loss pattern. Chronic graft versus host disease (GVHD), skin chronic GVHD, a HSCT regimen that included busulfan conditioning, and a family history of early male-pattern alopecia were all significantly associated with post-HSCT permanent alopecia (P less than .05 for all).

The patients with androgenetic alopecia may be experiencing an accelerated time course of a condition to which they are already genetically disposed, noted Dr. Song and her colleagues.

Psoriasis was commonly seen on the scalp, affecting 11 of the 14 patients with psoriasis (79%), and involved the face in five of the patients (36%). Just one patient had psoriasis elsewhere on the body. There was a nonsignificant trend towards human leukocyte antigen mismatch among patients who had psoriasis. Although “psoriasis may be a marker of persistent immune dysregulation,” the investigators said, they did not identify any associated risk factors that would point toward this mechanism in their analysis.

Twelve patients (14%) had vitiligo, with halo nevi seen in four of these patients. Children who were younger than age 10 years and those who received their transplant for primary immunodeficiency were significantly more likely to have vitiligo (P less than .05 for both). Specific possible mechanisms triggering vitiligo could include thymic dysfunction resulting in loss of self-tolerance, and donor alloreactivity against the patient’s host antigens, according to the authors.

Nail changes such as pterygium and nail pitting, ridging, or thickening were seen in just five patients, all of whom had chronic GVHD of the skin. “Nail changes are likely a result of persistent inflammation and immune dysregulation from chronic GVHD,” said Dr. Song.

These late effects “can significantly impact patients’ quality of life,” according to the authors, who called for larger studies that follow pediatric HSCT patients longitudinally, beginning before the transplant – and for more investigation into the pathogenesis of specific late effects.

Dr. Song reported no relevant conflicts of interest.

CHICAGO – Bone marrow transplantation is evolving as a promising treatment for patients with the most severe forms of epidermolysis bullosa.

“Is this a cure? It’s not,” Dr. Jakub Tolar, MD, PhD, said at the World Congress of Pediatric Dermatology. “It is, however, a path toward understanding how we can treat this grave disorder in a systemic way.”

MADRID – A four-drug induction regimen induced quicker and deeper remissions than sequential triplet regimens in patients with newly diagnosed multiple myeloma.

In addition, fast, deep remissions may lead to improved progression-free survival (PFS) following autologous stem cell transplantation (ASCT), said investigators from a U.K. Medical Research Council study.

In the phase 3 randomized, parallel group Myeloma XI study, very good partial responses (VGPR) or better were seen following induction in 79.5% of patients assigned to the quadruplet (KCRD) of carfilzomib (Kyprolis), cyclophosphamide, lenalidomide (Revlimid), and dexamethasone, compared with 60.8% for those assigned to cyclophosphamide, lenalidomide, and dexamethasone (CRD) and 52.8% for those assigned to cyclophosphamide, thalidomide, and dexamethasone (CTD), said Charlotte Pawlyn, MD, PhD, at the annual congress of the European Hematology Association.

“In our study, we see a very much deeper response after initial induction with the quadruplet regimen, compared with triplet regimens,” Dr. Pawlyn of the Institute of Cancer Research, London, said in an interview.

Medical Research Council investigators showed in the Myeloma IX study that among patients who had a less than VGPR to an immunomodulator-based triplet regimen such as CRD, a triplet regimen including the proteasome inhibitor bortezomib (Velcade) could improve both pre- and post-transplant response rates, and that the improved responses translated into improved PFS.

For the Myeloma XI study, the investigators employed the same response-adapted approach to compare outcomes following induction with the proteasome inhibitor–containing KCRD regimen and the lenalidomide- or thalidomide-based regimens.

Matching down to the allele level in umbilical cord blood transplantation between unrelated donors results in greater overall survival for those with nonmalignant diseases, such as aplastic anemia, researchers found in a retrospective study published in the Lancet Haematology.

The review (Lancet Haematol. 2017 Jul;4[7]:e325-33), the largest published on the topic, indicates that clinicians should change practice from the current standard of antigen-level matching, said Mary Eapen, MD, director of the Center for International Blood and Marrow Transplant Research (CIBMTR) in Wauwatosa, Wisconsin.

“Our findings,” Dr. Eapen wrote, “support a change in clinical practice to prioritization of units on allele-level HLA matching at HLA-A, HLA-B, HLA-C, and HLA-DRB1.”

Data were pulled from cases reported to the Center for International Blood and Marrow Transplant Research or the European Group for Blood and Marrow Transplant. Researchers looked at 1,199 donor-recipient matches of cord blood transplantation for diseases, such as severe combined immunodeficiency (SCID), non-SCID primary immunodeficiency, inborn errors of metabolism, severe aplastic anemia, and Fanconi anemia. Recipients could be as old as age 16, but most were age 5 or younger.

After adjustment for factors, including cytomegalovirus serostatus, the intensity of the conditioning regimen, and the total nucleated cell dose, the 5-year overall survival was 79% for transplants that were matched at all eight alleles at HLA-A, HLA-B, HLA-C and HLA-DRB1. These results compare with 76% after transplants with one mismatch, 70% with two mismatches, 62% with three mismatches, and 49% with 4 or more mismatches.

Mortality risks were significantly higher for patients who received transplants with two (P = .018), three (P = .0001), and four or more mismatches (P less than .0001), compared with those whose transplants were fully matched. There was no difference statistically between full matches and one mismatch, but the findings suggest that the mortality risk might prove significant with a larger sample size.

Researchers cautioned that, because most patients were age 5 or younger, the results might not be generalizable to older children.

Although HLA typing is available at CIBMTR for most blood cord transplants for nonmalignant diseases, full allele matches or just one mismatch are not the norm, Dr. Eapen wrote. Researchers said that they suspect this is because of difficulties finding matches or because a high total nucleated cell count is prioritized above HLA matching. They suggest clinicians change their decision making in this regard.
