Update: The hold on this trial has been lifted. Click here for additional details.
A trial of the chimeric antigen receptor (CAR) T-cell therapy JCAR015 has been placed on clinical hold following 3 patient deaths.
The trial, known as ROCKET, is a phase 2 study of adults with relapsed or refractory B-cell acute lymphoblastic leukemia.
The US Food and Drug Administration (FDA) placed a hold on the trial after 3 patients died of cerebral edema.
All 3 patients had received conditioning with fludarabine, and Juno Therapeutics, the company developing JCAR015, believes this may have caused the patients’ deaths.
Patients enrolled on the ROCKET trial previously received conditioning with cyclophosphamide alone, but investigators decided to add fludarabine in hopes of increasing efficacy.
The addition of fludarabine to conditioning had been shown to increase the efficacy of 2 of Juno’s other CAR T-cell therapies, JCAR014 and JCAR017, in phase 1/2 trials.
“However, since adding fludarabine to the preconditioning on the ROCKET trial, we have seen an increase in the incidence of severe neurotoxicity, which has, unfortunately, included 2 patient deaths that occurred last week from cerebral edema that appeared to be treatment-related,” Hans Bishop, Juno’s president and chief executive officer, said in a conference call.
“After the first of these 2 deaths, we immediately paused the trial for an internal review and review with our Data Safety Monitoring Board [DSMB] and the FDA. There was also 1 previous death from cerebral edema on the trial in May. After a review of that event, we, along with the FDA and our DSMB, concluded there were confounding factors, and a change in our plans at the time was not warranted.”
After the more recent deaths, Juno investigated several factors that could have contributed, including the conditioning regimen, patient characteristics, toxicity management, product characteristics, and cell dose.
“Although more than 1 factor may have contributed, based on our review of the data available . . . , we believe the addition of fludarabine, when combined with JCAR015, is the most likely and the most appropriately modifiable factor,” Bishop said.
“Indeed, with cy[clophosphamide] alone, which we have used in the greatest number of patients treated in the ROCKET trial to date, there have not been any treatment-related deaths, and the incidence of severe neurotoxicity is within the range of what we expected in light of the Memorial Sloan-Kettering experience [phase 1 trial of JCAR015].”
Therefore, Juno has proposed continuing the ROCKET trial using conditioning with cyclophosphamide alone.
In response to this request, the FDA has requested that Juno submit:
- A revised patient informed consent form
- A revised investigator brochure
- A revised trial protocol
- A copy of a presentation the company made to the FDA.
The FDA said it will expedite the review of these documents and expects to complete the review within 30 days of receiving them.
If the clinical hold on the ROCKET trial is lifted, Juno plans to continue the trial. However, the hold will likely impact the company’s goal of gaining FDA approval for JCAR015 in 2017.
Juno’s trials and plans for its other CD19-directed CAR-T cell product candidates are not affected by the clinical hold placed on ROCKET.
ROCKET is not the first trial of JCAR015 to be placed on hold. The phase 1 trial of the therapy was placed on clinical hold in 2014, after 2 patients died of cytokine release syndrome.
That hold was lifted following changes to enrollment criteria and dosing. Results from this trial were presented at ASCO 2015 and ASCO 2016.

DNA repair mutations crop up often in mPC
The prevalence of inherited mutations in DNA repair genes such as BRCA2 in men with metastatic prostate cancer may be as high as 12%, investigators in a multicenter study report.
The prevalence of presumably harmful mutations in men with metastatic disease was more than twice that of men with localized prostate cancer, and men with metastatic prostate cancer had a 3- to 19-fold higher risk for having mutations in individual DNA repair genes, compared with men without prostate cancer in a population-wide genetic sample, reported Colin C. Pritchard, MD, PhD, of the University of Washington in Seattle and colleagues.
“Because the high frequency of DNA repair gene mutations is not exclusive to an early-onset phenotype and is associated with clinically and histologically aggressive disease, with compelling evidence for therapeutic relevance, it may be of interest to routinely examine all men with metastatic prostate cancer for the presence of germline mutations in DNA repair genes,” the investigators suggest (N Engl J Med. 2016 July. doi: 10.1056/NEJMoa1603144).
The findings point to possible therapeutic interventions for men with advanced prostate cancer with identified germline mutations in DNA repair genes, such as poly (ADP-ribose) polymerase (PARP) inhibitors or platinum compound–based chemotherapy,
To date, the only genetic factors known to be associated with aggressive prostate cancer and prostate cancer–specific mortality are mutations in DNA repair genes such as BRCA1 and BRCA2, CHEK2, and PALB2. The frequency of mutations in these genes among men with localized prostate cancer in general is relatively low, accounting for just a few percentage points of familial prostate cancer cases in a sample unselected for family predisposition, the authors noted.
To determine the frequency of mutations in advanced disease, the investigators reviewed genetic data on 692 men with metastatic prostate cancer who were enrolled in one of seven cases series and were unselected for family history of cancer or age at diagnosis.
They used multiplex genetic sequencing assays to look for mutation in 20 DNA repair genes that are associated with autosomal dominant cancer predisposition syndromes.
They found 84 presumably harmful mutations in 82 men, for an overall prevalence of 11.8%. In contrast, the frequency of germline DNA repair mutations among 499 men in the Cancer Genome Atlas prostate cancer study, including men with high-risk disease, was 4.6%, the authors noted.
The mutations occurred in 16 different genes, including, in order of prevalence, BRCA2, ATM, CHEL2, BRCA1, RAD51D and PALB2. There were no significant differences in mutation frequencies by either family history of prostate cancer or age at diagnosis.
The authors also estimated the prevalence of DNA repair gene mutations among the general population by looking at a sample of 53,105 persons without a known diagnosis of cancer who were included in the Exome Aggregation Consortium. Men with metastatic prostate cancer had a fivefold risk for having any deleterious DNA repair mutation, compared with the general population (P less than .001).
The relative risk of mutations in individual genes for men with metastatic disease, compared with men in the control sample, ranged from 3.1 for CHEK2 (P = .002) to 18.6 for BRCA2 (P less than .001).
The study was supported by a Stand Up To Cancer–Prostate Cancer Foundation (SU2C-PCF) International Prostate Cancer Dream Team Translational Cancer Research Grant and awards from the National Institutes of Health, Department of Defense, and prostate cancer foundation. Several authors reported receiving research fees, grants, honoraria, and/or travel expenses from various pharmaceutical companies.

Fee schedule includes expansion of Diabetes Prevention Program
An expansion of the Diabetes Prevention Program (DPP), announced July 7 in the proposed Medicare Physician Fee Schedule for 2017, would allow recognized suppliers to submit claims to the Centers for Medicare & Medicaid Services for payment beginning Jan. 1, 2018.
The proposed expansion would allow patients across the United States to access community-based intervention that curbs diabetes and keeps families healthy, according to Patrick Conway, MD, CMS chief medical officer.
“This is part of our efforts for better care, smarter spending, and healthier people,” Dr. Conway said in a statement. The “proposal is an exciting milestone for prevention and population health.”
The Diabetes Prevention Program started in 2011 as an Affordable Care Act pilot program awarded to the National Council of YMCAs of the United States of America (Y-USA). Medicare patients at high risk for diabetes attended 16 intensive educational sessions in a group-based, classroom-style setting and practical training in long-term dietary change, increased physical activity, and behavior change strategies for weight control.
The pilot resulted in savings of $2,650 per enrollee over 15 months, according to CMS, compared with costs associated with nonprogram beneficiaries – enough to cover the cost of the program. Program participants also were shown to lose an average of about 5% of their body weight.
In March 2016, the U.S. Health and Human Services Department announced that the CMS Office of the Actuary had certified the pilot Diabetes Prevention Program model as a cost savings program that reduced net Medicare spending. HHS determined that the program demonstrated the ability to improve the quality of patient care without limiting coverage or benefits.
In the fee schedule proposal, CMS is suggesting that each health care provider who offers services as part of a CDC-recognized organization delivering DPP services obtain a National Provider Identification number to provide Medicare DPP services, allowing supplier enrollment beginning as early as Jan. 1, 2017. In addition, CMS envisions a payment structure tying payment for Medicare DPP services to the number of sessions attended by patients and the achievement and maintenance of minimum weight loss. Claims for payment under the Medicare DPP would be submitted following the achievement of core session attendance and minimum weight loss, and following maintenance session attendance and maintenance of minimum weight loss, according to the proposal.
CMS has not decided whether the Medicare DPP should be expanded nationally in the first year of the program or whether it should be phased in.
The American College of Physicians expressed support for DPP expansion and said that organization leaders plan to provide comments on the basic framework.
“As a practicing primary care internist myself, I am greatly encouraged that CMS is proposing substantial improvements to help me and my colleagues provide coordinated, patient-centered, high-value, and team-based care to our patients,” ACP President Nitin S. Damle, MD, said in a statement. “We look forward to providing CMS with detailed comments to support these improvements while recommending other changes to strengthen primary care.”
Robert E. Ratner, MD, chief scientific and medical officer for the American Diabetes Association agreed.
“Providing people with prediabetes with effective tools to prevent diabetes is a win for all of us,” Dr. Ratner said in a statement. “We appreciate HHS’s continued commitment to improving the nation’s health and helping us reduce the incidence and burden of diabetes across the country.”
Wanda Filer, MD, president of the American Academy of Family Physicians, said her organization was still analyzing the proposal, but that the expansion sounds positive for health care.
“We think the expansion is a great idea for patients,” she said in an interview, adding that it’s essential that doctors are reimbursed for preventive services. “Frankly, if you do the work, you need to get paid.”
CMS will accept comments on the proposed rule until Sept. 6. The proposed rule will appear in the July 15 Federal Register.

Treatment-free remissions achieved in patients with chronic myeloid leukemia
Treatment-free remission attempts are safe and are achievable in most patients with chronic myeloid leukemia (CML) in chronic phase, Timothy P. Hughes, MD, and his colleagues in the international ENESTop trial reported at the annual meeting of the American Society of Clinical Oncology.
The conclusion is based on follow-up data on 126 patients who achieved a sustained deep molecular response (MR4.5) after switching from imatinib (Gleevec) to nilotinib (Tasigna) and discontinued nilotinib. So far, these are the largest prospective treatment-free remission data set in a population of patients who achieved a sustained deep molecular response after switching from imatinib to nilotinib, Dr. Hughes, head of hematology at the University of Adelaide and his colleagues wrote in a poster presentation.
The ENESTop study is a single-arm, phase II study. Patients eligible for the study started treatment with imatinib when they were first diagnosed with CML, then switched to nilotinib for at least 2 years with the combined time on the drugs of at least 3 years and small amounts of leukemia cells remaining after the nilotinib treatment.
For the consolidation phase of the study, patients continued their nilotinib therapy for 1 year. Patients without confirmed loss of MR4.5 after 1 year were eligible to stop nilotinib. RQ-PCR (reverse transcriptase–polymerase chain reaction) was monitored every 12 weeks in the consolidation phase of the study and every 4 weeks during first 48 weeks of treatment-free remission. Nilotinib was restarted if patients had confirmed loss of deep molecular response (MR4 [consecutive BCR-ABL1IS greater than 0.01%]) or loss of major molecular response ([MMR] BCR-ABL1IS greater than 0.1%).
Of the 163 patients in the consolidation phase of the study, 126 entered treatment-free remission. Their median duration of tyrosine kinase inhibitor use prior to treatment-free remission was nearly 88 months, with a 53-month median duration of nilotinib therapy. At data cut-off, with median follow up of 50 weeks, 58% of the 126 patients were still in treatment-free remission at 48 weeks.
During treatment-free remission, 18 patients had confirmed loss of MR4 and 34 lost MMR. One patient had atypical transcript and came off the study. All but one of the 52 patients reinitiated nilotinib; 50 (98%) regained at least MMR by data cut-off, 48 (94%) regained MR4, and 47 (92%) regained MR4.5. One patient switched to another tyrosine kinase inhibitor at 22 weeks after restarting therapy.
Of those who restarted therapy, the median time was 12 weeks to regain MR4 and was 13 weeks to regain MR4.5. No new safety findings were observed on treatment.

Treatment-free remission attempts are safe and are achievable in most patients with chronic myeloid leukemia (CML) in chronic phase, Timothy P. Hughes, MD, and his colleagues in the international ENESTop trial reported at the annual meeting of the American Society of Clinical Oncology.
The conclusion is based on follow-up data on 126 patients who achieved a sustained deep molecular response (MR4.5) after switching from imatinib (Gleevec) to nilotinib (Tasigna) and discontinued nilotinib. So far, these are the largest prospective treatment-free remission data set in a population of patients who achieved a sustained deep molecular response after switching from imatinib to nilotinib, Dr. Hughes, head of hematology at the University of Adelaide and his colleagues wrote in a poster presentation.
The ENESTop study is a single-arm, phase II study. Patients eligible for the study started treatment with imatinib when they were first diagnosed with CML, then switched to nilotinib for at least 2 years with the combined time on the drugs of at least 3 years and small amounts of leukemia cells remaining after the nilotinib treatment.
For the consolidation phase of the study, patients continued their nilotinib therapy for 1 year. Patients without confirmed loss of MR4.5 after 1 year were eligible to stop nilotinib. RQ-PCR (reverse transcriptase–polymerase chain reaction) was monitored every 12 weeks in the consolidation phase of the study and every 4 weeks during first 48 weeks of treatment-free remission. Nilotinib was restarted if patients had confirmed loss of deep molecular response (MR4 [consecutive BCR-ABL1IS greater than 0.01%]) or loss of major molecular response ([MMR] BCR-ABL1IS greater than 0.1%).

FDA places CAR-T cell trial on hold following patient deaths
The Food and Drug Administration placed Juno Therapeutics’ phase II ROCKET trial, involving CAR-T cell therapy, on clinical hold following two treatment-related patient deaths caused by excess fluid accumulation in the brain.
The ROCKET trial is a single-arm, multicenter phase II study treating adult patients with relapsed or refractory B-cell acute lymphoblastic leukemia with an infusion of the patient’s own T cells that have been genetically modified to express a chimeric antigen receptor (CAR) that will bind to CD19-expressing leukemia cells. This treatment is referred to as JCAR015, and the ROCKET trial is only one of three current clinical trials testing its safety and efficacy.
Just before the ROCKET trial commenced, researchers added the chemotherapy drug fludarabine, which was successful in improving the performance of other immunotherapies, to the JCAR015 infusion. Researchers involved in the trial reported that the addition of this drug was likely the cause of the patient deaths.
Juno Therapeuticswill submit a revised trial protocol and patient consent form to the FDA before the hold is lifted, Juno reported in a written statement. The other trials led by Juno Therapeutics involving CAR-T cell product candidates are not affected.

Most interventional cardiologists don’t fully grasp radiation risks
PARIS – What most interventional cardiologists and electrophysiologists do not know about their health risks due to occupational radiation exposure and how best to protect themselves could fill a book – or better still, make for an illuminating 2-hour expert panel discussion at the annual congress of the European Association of Percutaneous Cardiovascular Interventions.
“There’s a problem of lack of awareness on the part of interventional cardiologists, and also of institutional insensitivity to the problem,” declared Emanuela Piccaluga, MD, an investigator in the eye-opening Healthy Cath Lab study. This Italian national study showed that cardiac catheterization laboratory staff had radiation exposure duration–dependent increased risks of cataracts, cancers, and skin lesions, as well as other radiogenic noncancer effects: anxiety and depression, hypertension, and hyperlipidemia.
Cardiologists at some European hospitals have to pay for their own lead aprons and other protective gear. And even if the hospital does pick up the bill, administrators often balk at authorizing replacement of a lead apron that has developed microfractures and cracks. They view these imperfections as cosmetic defects, unaware that the damage renders the apron less protective, according to Dr. Piccaluga of Niguarda Ca’ Granda Hospital in Milan.
Ariel Roguin, MD, head of interventional cardiology at Rambam Medical Center in Haifa, Israel, said every cardiologist working with radiation should understand the three principles of radiation reduction, which he refers to in shorthand as “TDS,” for Time, Distance, and Shielding. Radiation is here to stay in cardiology, he said, but interventionalists can maximize their safety by keeping the fluoroscopy time and number of acquired images down, standing as far away as possible from both the radiation source and patient while still getting the job done well, and using appropriate shielding routinely.
Dr. Roguin gained notoriety with his report that 26 of 30 interventional cardiologists with glioblastoma multiforme or other brain malignancies had left-hemisphere cancers and 1 had a midline malignancy; only 3 were right-sided (Eur Heart J. 2014 Mar;35[10]:599-600). That distribution is highly unlikely to be due to play of chance, given that an interventional cardiologist’s left side is the side that’s usually exposed to more radiation.
“We should form a wall against radiation. Apart from the leaded aprons, for every procedure we all should also use lead skirts going from the table to the floor to block backscatter, ceiling-mounted overhead radiation shields, special glasses to protect against cataracts, and thyroid collars. And it’s very important to wear a dosimeter with sound; it helps increase awareness of our exposure,” he said.
Dr. Roguin has been a pioneer in the use of a thin, 0.5-mm lead shield draped across the patient’s abdomen from the umbilicus down during radial-access angiography. In a 322-patient randomized trial, he and his coinvestigators showed that this practice results in a threefold reduction in radiation to the operator, albeit at the cost of doubling the patient’s radiation exposure (Catheter Cardiovasc Interv. 2015 Jun;85[7]:1164-70).
“We now routinely do our radials with the lead apron across the patient’s abdomen. We’ve reached the conclusion that we work with radiation in the cath lab every day for many years and the patient is there only once or twice in a lifetime, hopefully,” the cardiologist explained.
With the growing popularity of radial-access interventions, audience members wanted to know if there is an advantage in terms of radiation exposure to left versus right radial artery access. The answer is no, according to Dr. Roguin.
“There are several studies showing no difference in radiation exposure. Left radial artery access is faster, but you’re leaning on the patient and getting more radiation as a result, while with right radial access you have to do more catheter manipulation, which takes longer. Both approaches involve more radiation to the operator than the transfemoral approach,” he said.
Dr. Piccaluga presented highlights from the Healthy Cath Lab study, sponsored by the Italian Society of Invasive Cardiology and the Italian National Research Council’s Institute of Clinical Physiology. The study involved detailed self-administered questionnaires completed by 218 interventional cardiologists and electrophysiologists, 191 nurses, and 57 technicians regularly exposed to ionizing radiation in the cardiac cath lab for a median of 10 years, along with 280 unexposed controls.
A variety of health problems were more frequent in the cath lab personnel regularly exposed to radiation. Rates were consistently highest in the cardiologists, followed next by the cath lab nurses, and then the radiation technicians.
Rates of health problems were highest in the 227 individuals with at least 13 years of cath lab radiation exposure. For example, their adjusted risks of cataracts, hypertension, hypercholesterolemia, and cancers were respectively 9-, 1.7-, 2.9-, and 4.5-fold fold greater than in unexposed controls, as detailed in a recent report (Circ Cardiovasc Interv. 2016 April. doi: 10.1161/CIRCINTERVENTIONS.115.003273).
Dr. Piccaluga also shared data from several other pertinent recent studies in which she was a coinvestigator. In one, 83 cardiologists and nurses working in cardiac catheterization laboratories and 83 matched radiation-nonexposed controls completed a neuropsychological test battery. The radiation-exposed group scored significantly lower on measures of delayed recall, visual short-term memory, and verbal fluency, all of which are skills located in left hemisphere structures of the brain – the side with more exposure to ionizing radiation during interventional procedures (J Int Neuropsychol Soc. 2015 Oct;21[9]:670-6).
In another study, Dr. Piccaluga and her coinvestigators had participants perform an odor-sniffing test. Olfactory discrimination in the cardiac cath lab staffers was significantly diminished in a pattern that has been identified in other studies as an early signal of impending clinical onset of Alzheimer’s and Parkinson’s diseases (Int J Cardiol. 2014 Feb 15;171[3]:461-3).
And in yet another study, Dr. Piccaluga and her coworkers found that left and right carotid intima-media thickness as measured by ultrasound in cardiac cath lab personnel having high lifetime radiation exposure was significantly greater than in those with low exposure and in nonexposed controls. In the left carotid artery, but not the right, intimal-medial thickness was significantly correlated with a total occupational radiologic risk score.
Moreover, the Italian investigators found a significant reduction in leukocyte telomere length – a biomarker for accelerated vascular aging – in cardiac cath lab staff regularly exposed to ionizing radiation, compared with controls (JACC Cardiovasc Interv. 2015 Apr 20;8[4]:616-27).
All of these findings, she stressed, make a persuasive case for interventional cardiologists doing everything they can to protect themselves from unnecessary radiation exposure at all times.
How to best go about accomplishing this was the territory covered by Alaide Chieffo, MD, of San Raffaele Scientific Institute in Milan.
The patient-related factors germane to radiation dose – procedure complexity and body thickness – are outside physician control. But there are plenty of operator-dependent factors, including, for starters, procedural experience. In one classic study, Dr. Chieffo noted, Greek investigators showed that interventional cardiologists’ radiation exposure dose was 60% greater in their first year of practice than in their second year.
Distance from the patient is crucial, she observed, since the patient is the greatest source of radiation to the operator. If the operator is 35 cm from the patient, the radiation exposure is fourfold greater than at a distance of 70 cm. At a distance of 17.5 cm, the exposure intensity is 16-fold greater than at a 70-cm distance. And at 8.8 cm of distance, it’s 64 times greater.
Image acquisition is another key variable within the interventionalist’s control. Cine images entail 12- to 20-times greater radiation doses than those of fluoroscopy, so don’t resort to cine when fluoroscopy will do. Also, reducing the fluoroscopy frame rate from 15 to 7.5 frames per second significantly decreases the amount of radiation released while providing images of adequate quality for many procedures. Tight collimation, the use of manually inserted wedge filters, and thoughtful selection of tube angulations result in less radiation for both patient and physician. It has been shown that tube angulations that expose a patient to intense radiation levels increase the operator’s radiation exposure exponentially. The least-irradiating tube angulations are caudal posteroanterior 0°/30°– angulation for the left coronary main stem, cranial posteroanterior 0°/30°+ for the left anterior descending coronary artery bifurcation, and right anterior oblique views of 40° or more. Left anterior oblique projections are the most radiation intensive, according to a comprehensive study (J Am Coll Cardiol. 2004 Oct 6;44[7]:1420-8), Dr. Chieffo continued.
Panelist Ghada Mikhail, MD, of Imperial College London, said there is some relatively new operator protective gear available. She cited lightweight protective caps, for example, but an audience show of hands indicated almost no one uses them.
“Protectors for the breasts and gonads are available. You can wear them underneath the lead. The extra time to put them on is worthwhile,” she said.
“I think the risk of radiation is completely underestimated,” Dr. Mikhail added. “We have a responsibility to young trainees to teach them about radiation protection, which a lot of institutions and supervisors don’t do. That’s partly because a lot of them don’t know the details.”
All of the speakers indicated they had no financial conflicts regarding their presentations.

Left radial artery access is faster, but you’re leaning on the patient and getting more radiation as a result, while with right radial access you have to do more catheter manipulation, which takes longer. Both approaches involve more radiation to the operator than the transfemoral approach,” he said.
Dr. Piccaluga presented highlights from the Healthy Cath Lab study, sponsored by the Italian Society of Invasive Cardiology and the Italian National Research Council’s Institute of Clinical Physiology. The study involved detailed self-administered questionnaires completed by 218 interventional cardiologists and electrophysiologists, 191 nurses, and 57 technicians regularly exposed to ionizing radiation in the cardiac cath lab for a median of 10 years, along with 280 unexposed controls.
A variety of health problems were more frequent in the cath lab personnel regularly exposed to radiation. Rates were consistently highest in the cardiologists, followed next by the cath lab nurses, and then the radiation technicians.
Rates of health problems were highest in the 227 individuals with at least 13 years of cath lab radiation exposure. For example, their adjusted risks of cataracts, hypertension, hypercholesterolemia, and cancers were respectively 9-, 1.7-, 2.9-, and 4.5-fold fold greater than in unexposed controls, as detailed in a recent report (Circ Cardiovasc Interv. 2016 April. doi: 10.1161/CIRCINTERVENTIONS.115.003273).
Dr. Piccaluga also shared data from several other pertinent recent studies in which she was a coinvestigator. In one, 83 cardiologists and nurses working in cardiac catheterization laboratories and 83 matched radiation-nonexposed controls completed a neuropsychological test battery. The radiation-exposed group scored significantly lower on measures of delayed recall, visual short-term memory, and verbal fluency, all of which are skills located in left hemisphere structures of the brain – the side with more exposure to ionizing radiation during interventional procedures (J Int Neuropsychol Soc. 2015 Oct;21[9]:670-6).
In another study, Dr. Piccaluga and her coinvestigators had participants perform an odor-sniffing test. Olfactory discrimination in the cardiac cath lab staffers was significantly diminished in a pattern that has been identified in other studies as an early signal of impending clinical onset of Alzheimer’s and Parkinson’s diseases (Int J Cardiol. 2014 Feb 15;171[3]:461-3).
And in yet another study, Dr. Piccaluga and her coworkers found that left and right carotid intima-media thickness as measured by ultrasound in cardiac cath lab personnel having high lifetime radiation exposure was significantly greater than in those with low exposure and in nonexposed controls. In the left carotid artery, but not the right, intimal-medial thickness was significantly correlated with a total occupational radiologic risk score.
Moreover, the Italian investigators found a significant reduction in leukocyte telomere length – a biomarker for accelerated vascular aging – in cardiac cath lab staff regularly exposed to ionizing radiation, compared with controls (JACC Cardiovasc Interv. 2015 Apr 20;8[4]:616-27).
All of these findings, she stressed, make a persuasive case for interventional cardiologists doing everything they can to protect themselves from unnecessary radiation exposure at all times.
How to best go about accomplishing this was the territory covered by Alaide Chieffo, MD, of San Raffaele Scientific Institute in Milan.
The patient-related factors germane to radiation dose – procedure complexity and body thickness – are outside physician control. But there are plenty of operator-dependent factors, including, for starters, procedural experience. In one classic study, Dr. Chieffo noted, Greek investigators showed that interventional cardiologists’ radiation exposure dose was 60% greater in their first year of practice than in their second year.
Distance from the patient is crucial, she observed, since the patient is the greatest source of radiation to the operator. If the operator is 35 cm from the patient, the radiation exposure is fourfold greater than at a distance of 70 cm. At a distance of 17.5 cm, the exposure intensity is 16-fold greater than at a 70-cm distance. And at 8.8 cm of distance, it’s 64 times greater.
Image acquisition is another key variable within the interventionalist’s control. Cine images entail 12- to 20-times greater radiation doses than those of fluoroscopy, so don’t resort to cine when fluoroscopy will do. Also, reducing the fluoroscopy frame rate from 15 to 7.5 frames per second significantly decreases the amount of radiation released while providing images of adequate quality for many procedures. Tight collimation, the use of manually inserted wedge filters, and thoughtful selection of tube angulations result in less radiation for both patient and physician. It has been shown that tube angulations that expose a patient to intense radiation levels increase the operator’s radiation exposure exponentially. The least-irradiating tube angulations are caudal posteroanterior 0°/30°– angulation for the left coronary main stem, cranial posteroanterior 0°/30°+ for the left anterior descending coronary artery bifurcation, and right anterior oblique views of 40° or more. Left anterior oblique projections are the most radiation intensive, according to a comprehensive study (J Am Coll Cardiol. 2004 Oct 6;44[7]:1420-8), Dr. Chieffo continued.
Panelist Ghada Mikhail, MD, of Imperial College London, said there is some relatively new operator protective gear available. She cited lightweight protective caps, for example, but an audience show of hands indicated almost no one uses them.
“Protectors for the breasts and gonads are available. You can wear them underneath the lead. The extra time to put them on is worthwhile,” she said.
“I think the risk of radiation is completely underestimated,” Dr. Mikhail added. “We have a responsibility to young trainees to teach them about radiation protection, which a lot of institutions and supervisors don’t do. That’s partly because a lot of them don’t know the details.”
All of the speakers indicated they had no financial conflicts regarding their presentations.
EXPERT ANALYSIS FROM EUROPCR 2016
Bendamustine-based chemotherapy induces high CR rate in relapsed HL
Combination chemotherapy with bendamustine, gemcitabine, and vinorelbine can induce high complete response rates among patients with relapsed or refractory Hodgkin lymphoma (HL) who are candidates for autologous stem cell transplantation, final results of a phase II study show.
Among 59 patients enrolled in the multicenter study, 49 (83%) had responses, including 43 (73%) who achieved a complete response (CR), and 6 (10%) who had a partial response after 4 cycles of chemotherapy with bendamustine (Treanda), gemcitabine (Gemzar), and vinorelbine (BeGEV).
Of the 49 patients with responses, 43 went on to autologous stem cell transplant (ASCT), reported Armando Santoro, MD, from the Humanitas Cancer Center in Rozzano, Italy.
“These findings provide a strong rationale for further development of the BeGEV regimen,” the investigators wrote in a study published online in the Journal of Clinical Oncology (2016 Jul 5. doi: 10.1200/JCO.2016.66.4466).
The investigators had previously shown that a regimen of ifosfamide, gemcitabine, and vinorelbine (IEGV) as salvage chemotherapy prior to ASCT was associated with an 81% overall response rate (ORR) 54% CR rate.
Because bendamustine has shown good activity as monotherapy against relapsed/refractory HL, they conducted a phase II study with an IEGV-like regimen in which bendamustine would be substituted for ifosfamide, to determine whether the substitution could improve response rates.
They enrolled 59 consecutive patients aged 18 years and older with HL that had relapsed or was refractory to one previous line of chemotherapy. Patients were treated with gemcitabine 800 mg/m2 on days 1 and 4, vinorelbine 20 mg/m2 on day 1, and bendamustine 90 mg/m2 on days 2 and 3. Patients also received prednisolone 100 mg/day for days 1 to 4. The patients were treated for four 21-day cycles.
Patients who achieved either a complete or partial response after completion of the four planned cycles then underwent myeloablative therapy with carmustine or fotemustine plus etoposide, cytarabine, and melphalan, followed by reinfusion of mobilized CD34-positive circulating stem cells.
Grade 3 or 4 hematologic toxicities included thrombocytopenia and neutropenia, which occurred in eight patients each. Fifty-five of 57 total evaluable patients had successful mobilization and harvesting of CD34-positive cells, and, as noted before, 43 went on to ASCT.
After a median follow-up of 29 months, the 2-year progression-free survival (PFS) rate for the total population was 62%, and the overall survival rates was nearly 78%. For patients who went on to ASCT, the 2-year PFS rate was 81%, and the 2-year survival rate was 89%.
The authors noted that BeGV was associated with higher CR rates than IEGV, and with “excellent” stem cell mobilization activity and engraftment. Additionally, BeGV has a favorable toxicity profile, because of the absence of ifosfamide which is known to significantly increase risk for hemorrhagic cystitis.
“Because the number of novel agents that may be added in the pretransplantation therapy setting is growing, direct comparisons of combinations incorporating novel agents with BeGEV and other regimens will be necessary to identify the best salvage strategy for relapsed and refractory HL,” the authors wrote.
The study was supported in part by a grant from Mundipharma Pharmaceuticals. Two coauthors disclosed consulting/advisory roles and travel accommodations and expenses from the company.

CAC Progression No Better Than Most Recent CAC Score: Study
NEW YORK - Progression of the coronary artery calcification (CAC) score over time predicts the risk of cardiovascular disease, but it performs no better than the most recent CAC score, according to findings from the Cooper Center Longitudinal Study (CCLS).
"I must admit that I expected to find that the change in CAC was going to provide a lot of information about cardiovascular events, and was quite surprised when it didn't add much," Dr. Benjamin D. Levine from Cooper Clinic and University of Texas Southwestern Medical Center, Dallas, Texas told Reuters Health by email. "I was then also surprised when Dr. Andre Paixao, one of our cardiology fellows at the time (now at Emory), suggested that we look at the last CAC score as the best measure for risk attributable to CAC, and he turned out to be right!"
CAC correlates with overall atherosclerotic plaque and predicts incident coronary heart disease (CHD) events, CHD mortality, and total mortality, but only a few studies have evaluated the implications of CAC progression.
Dr. Levine and colleagues used CCLS data from 5,933 participants free of cardiovascular disease (CVD) at baseline to evaluate the relative contributions of baseline CAC score, follow-up CAC score, and CAC progression rates to the risk of incident CVD events.
At baseline, 2,870 (48%) individuals had CAC. These individuals were older, more likely to be on statin therapy, and had higher systolic blood pressure and lower cardiorespiratory fitness, according to the June 29th JACC Cardiovascular Imaging online report.
Individuals with detectable CAC at baseline had significantly higher total CVD event rates than those without detectable CAC (7.70 vs 1.44 per 1,000 person-years, respectively), as well as hard CVD event rates, i.e., CVD death, nonfatal myocardial infarction, or nonfatal atherosclerotic stroke (2.68 vs 1.14 per 1,000 person-years, respectively).
Rates of total CVD and CHD events increased across quartiles of CAC progression, but there was no independent association between CAC progression and CVD outcomes after adjustment for the follow-up CAC score.
"These findings greatly simplify the interpretation of CAC scores over time," Dr. Levine said. "Because it is so difficult to quantify 'change' (a score that goes from 1 to 2 is 100% change, but from 101 to 102 is 1% change), it has been hard for clinicians to wrap their minds around the additional risk information that is contained in follow up scores. Since it is not the calcium we are worried about anyway (calcified plaque generally doesn't rupture - it is the company it keeps that is important), what matters is the overall atherosclerotic burden, as reflected by the absolute CAC score. How fast it changes doesn't matter at all!"
"Don't worry about complicated formulas for quantifying change in CAC," Dr. Levine said. "Just use the latest score to calculate the risk associated with CAC. Now that new calculators are available (and some new ones coming from our work in this space), only the latest CAC score is needed to assess risk."
In an editorial, Dr. Prediman K. Shah from Cedars Sinai Hart Institute in Los Angeles writes, "So change in CAC score may be bad, indifferent, or possibly even good depending on what causes the change: progression of underlying atherosclerosis (potentially bad) versus increased density of calcification indicating a plaque stabilizing response (potentially good)."
Dr. Shah continues. "How to distinguish potential contributors to change in CAC score remains an important and at this time an unanswered question."
"Addition of other variables that incorporate regions of change, change in regional density and other volumetric aspect of CAC change, extracoronary calcification, and epicardial fat volume may improve the value and relevance of change in CAC score," Dr. Shah said. "Further studies are needed to address these issues."
Dr. Joseph Yeboah from Wake Forest Baptist Health, Winston-Salem, North Carolina, who has also researched the association between CAC scores and cardiovascular disease risk, told Reuters Health by email, "This happens to be the first study to show that CAC progression is not informative for CVD risk assessment. At the very best, this study makes the data mixed, which is not surprising given the challenge of using a change in a variable (CAC progression) as a predictor. Some researchers have suggested that CAC density progression instead of CAC score progression may be more appropriate."
"In my opinion, these results will have very little influence on how CAC is used presently for CVD risk assessment," he said. "To my knowledge, there is presently no guideline or recommendation regarding the use of CAC progression for CVD risk assessment. This is because of the inherent challenges in assessing CAC progression and the paucity of data."
"The ACC/AHA guidelines clearly recommend the use of CAC, not CAC progression," Dr. Yeboah concluded. "The take away message here is that physicians should not use CAC progression for CVD risk assessment. More research is needed to fully understand CAC progression."

SAN FRANCISCO – The opioid overdose crisis in the United States is now plainly evident in intensive care units (ICUs), finds a study of hospitals in 44 states conducted between 2009 and 2015.
During the study period, ICU admissions for opioid overdoses increased by almost half, investigators reported in a session and related press briefing an international conference of the American Thoracic Society. Furthermore, ICU deaths from this cause roughly doubled.
“This means the opioid use epidemic has probably reached a new level of crisis,” said lead investigator Jennifer P. Stevens, MD, an instructor in medicine at Harvard Medical School, and an adult intensive care physician at Beth Israel Deaconess Medical Center, both in Boston. “And this means that in spite of everything that we can do in the ICU – keeping them alive on ventilators, doing life support, doing acute dialysis, doing round-the-clock care, round-the-clock board-certified intensivist care – we are still not able to make a difference in that mortality.”
Dr. Stevens added that any ICU admission for overdose from opioids is a preventable admission. “So if we have an increase in mortality of this population, we have a number of patients who have preventable deaths in our ICU,” she said.
Efforts to track this epidemic on a national level are important, she said, and the U.S. Centers for Disease Control and Prevention has been investigating opioid overdoses in some cities, including Boston, as they would any epidemic.
The factors driving the observed trends could not be determined from the study data, Dr. Stevens said. But state-specific patterns that show, for example, higher baseline rates and greater increases over time in ICU admissions for opioid overdose in Massachusetts and Indiana may be a starting point for investigation.
Certain practices in the ICU may also be inadvertently contributing. “I imagine that a patient who comes in with an opioid overdose can cause harm to themselves in a number of ways, and the things that we try to do to help them might cause harm in other ways as well,” she said. “So in an effort to try to maintain them in a safe, ventilated state, we might give them a ton of sedation that then prolongs their time on the ventilator. That’s sort of a simple example of how the two could intersect to have a multiplicative effect of harm.”
The idea for the study arose because ICU staff anecdotally noticed an uptick in admissions for opioid use disorder. “Not only were we seeing more people coming in, but we were seeing sicker people coming in, and with the associated tragedy that comes with a lot of young people coming in with opioid use disorder,” Dr. Stevens said. “We wanted to see if this was happening nationally... We asked, is this epidemic now reaching the most technologically advanced parts of our health care system?”
The investigators studied hospitals providing data to Vizient (formerly the University HealthSystem Consortium) between 2009 and 2015. The included hospitals – about 200 for each study year – were predominantly urban and university affiliated, but representation of community hospitals increased during the study period.
Ultimately, analyses were based on a total of 28.2 million hospital discharges of patients aged 18 years or older, which included 4.9 million ICU admissions.
Results reported at the meeting showed that 27,325 patients were admitted to the study hospitals’ ICUs with opioid overdose during the study period, as ascertained from billing codes.
Opioid overdose was seen in 45 patients per 10,000 ICU admissions in 2009 but rose to 65 patients per 10,000 ICU admissions in 2015, a 46% increase.
Furthermore, ICU deaths due to opioid overdose rose by 87% during the same time period, and mortality among patients admitted to the unit with overdose rose at a pace of 0.5% per month.
“This is somewhat unusual because a lot of times, when we are admitting more people to our ICUs or examining [a trend] further, mortality actually goes down. This is partly because maybe we are doing more for them and we are taking care of them in an aggressive way. But it’s also because we are admitting less sick people because we are more aware of the issue,” Dr. Stevens said. “And we saw the opposite of this – we saw that the mortality was going up.”
The use of billing data was a specific means but not a sensitive means of identifying opioid overdoses, she noted. Therefore, the observed values are likely underestimates of these outcomes.
Addressing the opioid overdose epidemic will require a multifaceted approach, according to Dr. Stevens, who disclosed that she had no relevant conflicts of interest.
“Folks are doing very impressive work in the community trying to make sure EMTs and other first responders have access to the tools that they need in those settings,” she said. “But one thing we haven’t approached before is the care that we provide in the ICU, and maybe that’s a space that we need to think more prospectively about.”
