Study Overview

Objective. To assess usability and patient perceptions of the sarilumab auto-injector device  (“sarilumab pen”) among patients with moderate-to-severe rheumatoid arthritis (RA).

Design. 12-week, randomized, parallel-group usability study.

Setting and participants. The study was conducted at 53 centers in 6 countries. Inclusion criteria were a diagnosis of RA (as defined by American College of Rheumatology/ European League Against Rheumatism 2010 Criteria) of ≥ 3-month disease duration, willing and able to self inject, continuous treatment with 1 or a combination of nonbiologic disease modifying antirheumatic drugs (except leflunomide in combination with methotrexate); and moderatly to severely active RA, defined as 4/66 swollen joint, 4/68 tender joints, and high-sensitivity C-reactive protein (hsCRP) measurement ≥ 4 mg/L. Exclusion criteria were age

Patients were randomized 1:1:1:1 to sarilumamb 150 or 200 mg every 2 weeks administered by single-use, disposable, prefilled pen or pre-filled syringe. Randomization method was not reported.

Main outcomes measures. The primary endpoint was number of “product technical failures” (PTFs). Patients randomized to the pen were given a diary that had questions related to their ability to remove the cap, start the injection, and complete the injection. Participants were asked to answer the questions each time they used the pen. If the response was “no” to any of the 3 questions, this was considered a “product technical complaint” (PTC). PTCs that had a validated technical cause based on pen evaluation and analysis were considered PTFs.

In addition, patient perceptions and satisfaction with the pen were assessed via questionnaire. At baseline, patients were asked about injections and prior experience with self-injection, and at 12 weeks they were asked about their experiences in using the pen. Other outcomes assessed included adverse events and pharmokinetic parameters.

Results. 217 participants were enrolled: 108 patients were in the pen group (56 randomized to 150 mg and 52 randomized to 200 mg) and 109 were in the syringe group (53 randomized to 150 mg and 56 randomized to 200 mg). Completion rates were similar among groups. Sixteen patients discontinued due to treatment-emergent adverse events. There were no PTFs. There was one PTC, in which the user accidently bumped the pen, which expelled the drug onto the floor.

At baseline, before the first injection, the majority of patients reported that they were not afraid of needles (58%), had past experience with self-injections (55%), and were either “very confident” or “extremely confident” regarding self-injections (55%). After the 12-week assessment phase, when asked about their overall level of satisfaction, 98% of patients reported they were “satisfied” or “very satisfied” with the sarilumab pen.

Treatment emergent adverse events occurred in 66% of patients, with no clinically meaningful differences leading to discontinuation in the pen and syringe groups. The most common adverse events were infections and neutropenia.

Conclusion. Patients successfully completed self-injections with the sarilumab pen and found it easy to use.

Commentary

Rheumatoid arthritis (RA) is a common immune-mediated disease characterized by chronically progressive inflammation and destruction of joints and associated structures, resulting in significant morbidity, mortality, and disability. Improved understanding of RA disease pathogenesis in recent years has led to the development of new biologic treatments designed to target specific elements of the RA inflammatory response.

Sarilumab is an interleukin-6 blocker that was approved in the US in 2017 for the treatment of adult patients with moderately to severely active RA who have had an inadequate response or intolerance to one or more disease-modifying antirheumatic drugs. While a syringe form of this drug is currently available, at the time of this writing the pen has not yet been released.

In this real-world usability study sponsored by Sanofi, there were no technical difficulties with using the pen. Most patients thought the pen was easy or very easy to use, and safety and effeicacy appeared to be generally comparable between the pen and syringe. The pen also offers safety protection features that prevent needlestick injury.

The authors of the current study noted that results from previous studies have shown that patients with RA favor treatment devices that are easy to use, convenient, less painful, and take less time to use, and patients have demonstrated a preference for autoinjector devices over more conventional methods of treatment administration [1–3], such as syringes. Pens have been well accepted for the treatment of other chronic health conditions, including diabetes mellitus, migraine headaches, and growth hormone deficiency, and subcutaneous administration of a tumor necrosis factor (TNF) inhibitor via pen has also been accepted for the treatment of RA [1]. As RA requires lifelong treatment, the use of a pen that is ergonomically designed to take into account the manual dexterity issues relevant to this patient population could potentially enhance compliance.

Applications for Clinical Practice

A prefilled pen was well accepted and associated with favorable patient perceptions, indicating that this delivery system may be a viable option for RA patients who are prescribed sarilumab.

Neuroimaging studies have consistently reported reduced activation of the medial prefrontal cortex (mPFC) in patients with posttraumatic stress disorder (PTSD) while they recall and imagine stressful personal events. During script-driven imagery (SDI) sessions, patients with PTSD exhibit increased psychophysiologic (eg, heart rate, skin conductance, and facial electromyographic) responses to trauma-related memories. However, the origin of the responses remained unclear. Are they familial, acquired, or resulting from trauma exposure?

Researchers from Harvard University, University of California Los Angeles, and University of New England conducted a study of 26 male identical twin pairs to help find the answer. The participants were divided into 4 groups: combat-exposed with PTSD (ExP+), their combat-unexposed twins without PTSD, combat-exposed participants without PTSD, and their combat-unexposed twins without PTSD. They engaged in SDI during functional magnetic resonance (fMRI) imaging and concurrent skin conductance measurement.

The results of the fMRI tests showed diminished activation in the medial prefrontal cortex of the patients with PTSD compared with the other groups. The SC response scores did not correlate significantly with PTSD symptom severity.

Contrary to the researchers’ predictions, mPFC activation was not inversely correlated with PTSD symptom severity. However, they say their finding of reduced mPFC activation in the ExP+ group provides evidence that the abnormality is an acquired characteristic. If those findings are replicated, such objectively measured biologic characteristics could potentially aid in diagnosing PTSD or assessing treatment response.

According to the VA, 8,744,000 veterans served in the Armed Forces in the time between the Gulf of Tonkin incident and the signing of the Paris Peace Accords.1 Of those, 3,403,000 were deployed to Southeast Asia. Those who served during this period often were exposed to unique environmental hazards, such as commonly used pesticides and herbicides, as well as diseases attributed to the tropical environment, such as fungal infections, and there were more than 40,000 reported cases of malaria. Upon returning home, these veterans faced a tough readjustment that often magnified the stress associated with combat.

Today, the VA recognizes 8 conditions related to service in Vietnam for the purposes of establishing service-connection: soft tissue sarcoma, non-Hodgkin lymphoma, Hodgkin disease, chloracne, porphyria cutanea tarda, respiratory cancers, multiple myeloma, prostate cancer, acute peripheral neuropathy, and spina bifida in offspring. As the veterans of this conflict age into their retirement years, the VA now also faces the challenge of providing care to this growing senior population.

Obinutuzumab (Gazyva)

Health Canada has expanded the approved use of obinutuzumab (Gazyva®).

The anti-CD20 monoclonal antibody is now approved for use in combination with chemotherapy to treat patients with previously untreated follicular lymphoma (FL) that is advanced (stage II bulky, stage III, or stage IV).

In patients who respond to this treatment, obinutuzumab monotherapy can be given as maintenance.

Health Canada previously approved obinutuzumab for the following indications:

• In combination with chlorambucil to treat patients with previously untreated chronic lymphocytic leukemia
• First in combination with bendamustine, then as monotherapy, in FL patients who relapsed after or are refractory to a rituximab-containing regimen.

Phase 3 results

Health Canada’s latest approval of obinutuzumab is based on results from the phase 3 GALLIUM study, which were published in NEJM in October 2017. The following are updated data from the product monograph.

GALLIUM included 1385 patients with previously untreated non-Hodgkin lymphoma, and 1202 of these patients had previously untreated, advanced FL.

Half of the FL patients (n=601) were randomized to receive obinutuzumab plus chemotherapy (followed by obinutuzumab maintenance for up to 2 years), and half were randomized to rituximab plus chemotherapy (followed by rituximab maintenance for up to 2 years).

The different chemotherapies used were CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone), CVP (cyclophosphamide, vincristine, and prednisone), and bendamustine.

At a median observation time of 41.1 months, the overall response rate was 91% in the obinutuzumab arm and 88% in the rituximab arm. The complete response rates were 28% and 27%, respectively.

The median progression-free survival was not reached in either arm. The hazard ratio, for obinutuzumab compared to rituximab, was 0.72 (95% CI, 0.56-0.93, P=0.0118).

The estimated 3-year progression-free survival was 78.9% in the rituximab arm and 83.4% in the obinutuzumab arm.

Safety was evaluated based on all 1385 patients in the study, 86% of whom had FL and 14% of whom had marginal zone lymphoma.

Serious adverse events (AEs) occurred in 50% of patients in the obinutuzumab arm and 43% in the rituximab arm. Fatal AEs occurred in 5% and 4%, respectively. Infections and second malignancies were the leading causes of these deaths.

During the monotherapy period, the most common AEs (≥ 5%) in patients treated with obinutuzumab were cough (21%), neutropenia (19%), upper respiratory tract infection (15%), viral upper respiratory tract infection (15%), diarrhea (13%), arthralgia (10%), fatigue (9%), sinusitis (9%), infusion reactions (8%), pneumonia (8%), herpes zoster (8%), lower respiratory tract infection (7%), pyrexia (7%), back pain (6%), headache (6%), urinary tract infection (6%), nausea (6%), bronchitis (5%), and vomiting (5%).

Grade 3-4 AEs (≥1%) in patients treated with obinutuzumab included neutropenia (17%), pneumonia (3%), and febrile neutropenia (2%). There were 2 deaths due to pneumonia in the obinutuzumab arm.

Preclinical research suggests ibrutinib could treat G-CSFR-mutant myeloid disorders.

“Mutations in G-CSFR have a harmful effect on the production of neutrophils and are reported in patients with several blood disorders, including severe congenital neutropenia, chronic neutrophilic leukemia, and acute myeloid leukemia,” said Ken Greis, PhD, of the University of Cincinnati in Ohio.

“Unfortunately, despite years of research, the malignant signaling of the mutated G-CSFRs is not well understood.”

With this in mind, Dr Greis and his colleagues created a comprehensive signaling network of normal and mutated G-CSFR. Their goal was to understand how abnormal cellular signaling from the mutant receptors results in disease development.

The researchers described this work in Leukemia.

“We are able to look at . . . phosphorylation that results in phosphate groups being attached to the amino acid tyrosine (Tyr) in proteins,” Dr Greis explained. “These phosphorylation events (pTyr) can act as switches to activate or inactivate proteins and/or specific cellular processes.”

“By evaluating pTyr activity in the normal versus mutant receptor cells, we can produce a network similar to a wiring diagram of cellular regulation. Observed disruptions at any of the nodes in the network for the mutated receptors can then be investigated further to understand and perhaps target the abnormal signaling corresponding to the disease.”

This analysis of pTyr activity revealed that G-CSFR mutants had aberrant activation of BTK, as well as abnormal kinetics of canonical STAT3, STAT5, and MAPK phosphorylation.

“When we first got these results, one of the most exciting things was that BTK was already the target of an FDA-approved drug, ibrutinib . . .,” said study author H. Leighton Grimes, PhD, of the University of Cincinnati.

The researchers tested ibrutinib in cells with mutant and wild-type G-CSFR and found the drug killed the mutant cells but not the wild-type cells. This was the case in myeloid progenitor 32D cell lines and primary human CD34+ umbilical cord blood cells.

“Progenitor cells expressing mutated G-CSFR in animal models and in human blood cells also showed enhanced sensitivity to ibrutinib compared to the normal G-CSFR, thus confirming that the mutated cells could likely be eliminated by treatment with ibrutinib and may represent an effective therapy for these patients,” Dr Grimes said.

Ibrutinib also demonstrated synergy with the JAK1/2 inhibitor ruxolitinib. G-CSFR-mutant CD34+ cells were sensitive to each drug alone, but combining them “dramatically enhanced” the sensitivity, according to the researchers.

“These data demonstrate the strength of global proteomics approaches, like the pTyr profiling used here, in dissecting cancer-forming pathways and points to the possibility that ibrutinib could be an effective therapy for myeloid leukemias with G-CSFR mutations,” Dr Greis said.

“Further studies are needed to determine if these findings will be applicable in patient samples, but the hope is that clinical trials are just around the corner, since we’re investigating a drug that has already been found to be safe by the FDA.”

Preclinical research suggests ibrutinib could treat G-CSFR-mutant myeloid disorders.

“Mutations in G-CSFR have a harmful effect on the production of neutrophils and are reported in patients with several blood disorders, including severe congenital neutropenia, chronic neutrophilic leukemia, and acute myeloid leukemia,” said Ken Greis, PhD, of the University of Cincinnati in Ohio.

“Unfortunately, despite years of research, the malignant signaling of the mutated G-CSFRs is not well understood.”

An investigative report has unearthed potential conflicts of interest among physicians who serve on advisory panels for the US Food and Drug Administration (FDA).

The investigation revealed that some FDA advisers are receiving significant post-hoc payments from the makers of drugs they reviewed.

The investigation also uncovered relationships between advisers and drug companies that predate drug reviews.

Journalist Charles Piller and his colleagues conducted this investigation and detailed the results in Science.

The report includes data—from the federal Open Payments website—on 107 physicians who voted on FDA advisory committees between 2013 and 2016.

Forty of these advisers received more than $10,000 in post-hoc earnings or research support from the makers of drugs they reviewed or from competing drug companies.

Twenty-six advisers received more than $100,000, and 7 advisers received more than $1 million.

The 17 top earners received more than $300,000 each. For these advisers, 94% of their earnings came from the makers of drugs they previ­ously reviewed or from those companies’ competitors.

The data also show that some advisers received funds from drug companies concurrent with or in the year before their advisory service.

Of the 17 top-earning advisers, 11 received financial sup­port from competing companies on one or more of the drugs they reviewed. Five advisers also received support from the makers of one or more of the drugs reviewed.

The FDA did not disclose this information to the public or issue waivers for these potential conflicts. The FDA can issue a waiver to allow the participation of an adviser with an active conflict or one that ended in the year before a vote, as long as the adviser in question can provide expertise that cannot be provided by someone else.

It is possible that the FDA dismissed the aforementioned financial ties that predated drug reviews, deciding these relationships were not conflicts and did not require a waiver. However, it is also possible that the FDA did not know about these potential conflicts.

Piller and his colleagues were unable to determine what the FDA knew, as the agency refused to release disclosure documents, discuss individual advisers, or explain what steps, if any, the FDA takes to validate advisers’ disclosures.

SAN DIEGO – More than 16% of emergency department sepsis patients are not admitted to the hospital, preliminary results from a large retrospective cohort study found.

“Nothing is really known about this topic,” lead study author Ithan D. Peltan, MD, said in an interview at an international conference of the American Thoracic Society. “In previous research, we’ve been focused on patients with sepsis who are admitted to the hospital. We have never thoroughly recognized that a fair number of patients who meet clinical criteria for sepsis in the emergency department are actually triaged to outpatient management. We don’t really know anything about these patients. What are their clinical characteristics and what are their outcomes like? And what are the factors that are leading them to be discharged from the ED rather than be admitted to the hospital?”

To find out, he and his associates retrospectively reviewed the medical records of 12,002 adult ED patients who met criteria for sepsis at two tertiary hospitals and two community hospitals in Utah between July 2013 and December 2016. They excluded trauma patients, those who left the ED against medical advice, those who were discharged to hospice or who died in the ED, and eligible patients’ repeat ED encounters. Patients transferred to another acute care facility were considered admitted, while transfers to non-acute care such as skilled nursing or psychiatric facilities were classified as discharges. Next, Dr. Peltan and his associates employed inverse probability weights using a propensity score for ED discharge based on age, sex, Charlson score, ED acuity score, initial ED vital signs, white blood cell count, lactate, sequential organ failure assessment (SOFA)score, busyness of the ED, and study hospital to compare 30-day mortality between patients admitted to the hospital versus those discharged from the ED.

Of the 12,002 patients included in the analysis, 10,032 (83.6%) were admitted, while 1,970 (16.4%) were discharged. Compared with admitted patients, discharged patients were younger (a mean of 53 vs. 60 years, respectively; P less than .001); more likely to be female (65% vs. 55%; P less than .001); more likely to be nonwhite or Hispanic (21% vs 17%; P less than .001), and had fewer comorbidities and physiologic derangements. In addition, crude mortality at 30 days was lower in discharged versus admitted patients (1.0% vs. 6.2%, respectively; P less than .001). After the propensity-adjusted analysis, there was no significant difference in 30-day mortality for discharged vs. admitted sepsis patients (adjusted odds ratio 1.0).

“We were worried that discharged ED sepsis patients were being mismanaged and weren’t going to do well as similar patients who were admitted to the hospital,” Dr. Peltan said. “This analysis is still a work in progress, but with that caveat, our findings so far suggest that physicians are making pretty good decisions overall.”

The researchers also found that, among 89 ED physicians who cared for 20 or more eligible patients, some did not discharge any of their sepsis patients, while others discharged 39% of their sepsis patients. “That was surprising,” Dr. Peltan said. “This could mean that some hospital sepsis admissions depend on physician practice style more than the patient’s condition or treatment needs.”

LIVERPOOL, ENGLAND – Most patients with rheumatic diseases appear happy to switch from biologics to biosimilars and experience no issues, although the biosimilar they are being switched to may be important, according to data from three separate poster presentations at the British Society for Rheumatology annual conference.

Sara Freeman/MDedgeNews

“We know our biologic costs are incrementally increasing, but it’s still very hard for some patients to get onto these drugs,” Dr. Kitchen said. She hopes that with the cost-savings being made from the switch, it could help with negotiations to lower the threshold at which patients become eligible for biologic/biosimilar use, thus enabling more patients in need to be treated.

“I think these data have given confidence that patients can switch onto a biosimilar, and that the real-world experience matches what we’re seeing in trials,” Dr. Kitchen said. “We haven’t had a negative experience, and that’s what patients and we were worried about.”

In a separate poster presentation, Kavina Shah, MBBS, and her associates from Northwick Park Hospital, London, reported their experience of switching 115 patients with RA from etanercept to the biosimilar Benepali between January and June 2017.

They conducted a prospective study in which patients were offered an education session and then attended a clinic appointment set up to manage the switch. Patients were assessed by various objective and subjective means before and 4 months after the switch.

Dr. Shah and her associates found that 43% of patients were pleased with the switch. Part of the reason patients might have been happy with the switch was the easier mode of administration, they observed: “Patients commented on the easier technique and less manual dexterity required.”

However, almost a quarter (23%) of patients were not happy with the switch, with others being indifferent (7%) or unsure (8%).

Patients were also asked how they felt their RA was after the switch, and 75% responded that it was no different, 11% said it had improved, and 17% said it was worse.

The mean Disease Activity Score in 28 joints (DAS28) values were significantly lower in patients after the switch than before (2.66 vs. 2.97; P = .0019). “This could be explained by the lower levels of immunogenicity with Benepali,” Dr. Shah and her coauthors wrote on their poster. Alternatively, it could be an artifact introduced by lower rates of anxiety at follow-up, they said.

There were also statistically nonsignificant improvements in health assessment questionnaire (HAQ) and European Quality of Life-5 Dimensions (EQ-5D) scores.

Taken together, these findings are “reassuring,” Dr. Shah and her associates noted, and “should positively encourage clinicians and patients to switch to biosimilars in order to optimize the cost saving to the NHS.”

Not all biosimilar switches may go as smoothly as switching from TNF inhibitors, as Muhammad K. Nisar, MBBS, reported in another poster presentation at the conference. Dr. Nisar, a consultant rheumatologist for Luton (England) and Dunstable Hospital University Trust, reported his center’s experience of switching patients on rituximab (Rituxan) to biosimilar rituximab (Truxima).

Of 44 patients who were established on rituximab, 39 were eligible to make the switch. Four patients had stopped taking rituximab before the switch took place and one patient remained on the originator. As of October 2017, 24 (61.5%) of patients had actually made the switch.

“All were happy to switch after receiving a letter and having the opportunity to contact if necessary,” Dr. Nisar reported. “At group level there were no major differences in disease outcomes and 80% reported no issues.”

However, five (20%) patients developed a severe serum sickness reaction early on with loss of efficacy. This happened in the first week after the second dose of the biosimilar was given, Dr. Nisar explained. No obvious reason could be found, but two patients required emergency hospital treatment within 24 hours.

“Our experience of switching rituximab patients is certainly not as smooth as it was for infliximab or and etanercept,” Dr. Nisar said. While he said “they support routine switching from originator to biosimilar,” he noted that “close monitoring is required, certainly in the first week of dose administration.”

All authors had nothing to disclose.

LIVERPOOL, ENGLAND – Most patients with rheumatic diseases appear happy to switch from biologics to biosimilars and experience no issues, although the biosimilar they are being switched to may be important, according to data from three separate poster presentations at the British Society for Rheumatology annual conference.

“We know our biologic costs are incrementally increasing, but it’s still very hard for some patients to get onto these drugs,” Dr. Kitchen said. She hopes that with the cost-savings being made from the switch, it could help with negotiations to lower the threshold at which patients become eligible for biologic/biosimilar use, thus enabling more patients in need to be treated.

“I think these data have given confidence that patients can switch onto a biosimilar, and that the real-world experience matches what we’re seeing in trials,” Dr. Kitchen said. “We haven’t had a negative experience, and that’s what patients and we were worried about.”

In a separate poster presentation, Kavina Shah, MBBS, and her associates from Northwick Park Hospital, London, reported their experience of switching 115 patients with RA from etanercept to the biosimilar Benepali between January and June 2017.

They conducted a prospective study in which patients were offered an education session and then attended a clinic appointment set up to manage the switch. Patients were assessed by various objective and subjective means before and 4 months after the switch.

Dr. Shah and her associates found that 43% of patients were pleased with the switch. Part of the reason patients might have been happy with the switch was the easier mode of administration, they observed: “Patients commented on the easier technique and less manual dexterity required.”

However, almost a quarter (23%) of patients were not happy with the switch, with others being indifferent (7%) or unsure (8%).

Patients were also asked how they felt their RA was after the switch, and 75% responded that it was no different, 11% said it had improved, and 17% said it was worse.

The mean Disease Activity Score in 28 joints (DAS28) values were significantly lower in patients after the switch than before (2.66 vs. 2.97; P = .0019). “This could be explained by the lower levels of immunogenicity with Benepali,” Dr. Shah and her coauthors wrote on their poster. Alternatively, it could be an artifact introduced by lower rates of anxiety at follow-up, they said.

There were also statistically nonsignificant improvements in health assessment questionnaire (HAQ) and European Quality of Life-5 Dimensions (EQ-5D) scores.

Taken together, these findings are “reassuring,” Dr. Shah and her associates noted, and “should positively encourage clinicians and patients to switch to biosimilars in order to optimize the cost saving to the NHS.”

Not all biosimilar switches may go as smoothly as switching from TNF inhibitors, as Muhammad K. Nisar, MBBS, reported in another poster presentation at the conference. Dr. Nisar, a consultant rheumatologist for Luton (England) and Dunstable Hospital University Trust, reported his center’s experience of switching patients on rituximab (Rituxan) to biosimilar rituximab (Truxima).

Of 44 patients who were established on rituximab, 39 were eligible to make the switch. Four patients had stopped taking rituximab before the switch took place and one patient remained on the originator. As of October 2017, 24 (61.5%) of patients had actually made the switch.

“All were happy to switch after receiving a letter and having the opportunity to contact if necessary,” Dr. Nisar reported. “At group level there were no major differences in disease outcomes and 80% reported no issues.”

However, five (20%) patients developed a severe serum sickness reaction early on with loss of efficacy. This happened in the first week after the second dose of the biosimilar was given, Dr. Nisar explained. No obvious reason could be found, but two patients required emergency hospital treatment within 24 hours.

“Our experience of switching rituximab patients is certainly not as smooth as it was for infliximab or and etanercept,” Dr. Nisar said. While he said “they support routine switching from originator to biosimilar,” he noted that “close monitoring is required, certainly in the first week of dose administration.”

All authors had nothing to disclose.

Direct oral anticoagulants were associated with decreased bleeding risk versus warfarin in a recent retrospective analysis of primary care databases.

Apixaban (Eliquis) was associated with decreased risk of major bleeding events versus warfarin both in patients with atrial fibrillation (AF) and those prescribed anticoagulants for other causes, according to study results.

Rivaroxaban (Xarelto) was associated with a decrease in risk of intracranial bleeding, compared with warfarin in patients without AF, as was dabigatran (Pradaxa), reported Yana Vinogradova, a research statistician in the division of primary care at the University of Nottingham, England, and her coauthors.

An increased risk of all-cause mortality was seen with both rivaroxaban and low-dose apixaban, possibly because more patients died of age-related causes while on these direct oral anticoagulants (DOACs), they reported.

“This large observational study, based on a general population in a primary care setting, provides reassurance about the safety of DOACs as an alternative to warfarin across all new incident users,” Ms. Vinogradova and her colleagues said in the BMJ.

Evidence establishing the noninferiority of DOACs to warfarin comes mostly from controlled trials in AF leaving “residual concerns” about the safety of these newer agents in real world settings, where a broader range of patients may receive them, they added.

Accordingly, they conducted an analysis based on patient data from two U.K. primary care databases that were representative of the national population, according to the researchers.

A total of 196,061 patients were represented in the study, including 103,270 (53%) with AF and 92,791 (47%) who received anticoagulants for other reasons.

A total of 67% of patients received warfarin, though its use declined from 98% in 2011, the beginning of the study period, to 23% in 2016, the end of the study period. Over that same time period, use of rivaroxaban rose from 1% to 42%, and use of apixaban rose from 0% to 31%, while dabigatran use peaked in 2013 at 10%, dropping to 3% by 2016.

Edoxaban was excluded from the study because it was not licensed in the United Kingdom until the end of 2015, investigators said.

For patients with AF, apixaban was linked to a lower major bleeding risk, both versus warfarin (adjusted hazard ratio, 0.66; 95% confidence interval, 0.54-0.79) and versus rivaroxaban, the published data show. Apixaban was associated with a lower risk of intracranial bleed versus warfarin in patients with AF (aHR, 0.40; 95% CI, 0.25-0.64) as was dabigatran (aHR, 0.45; 95% CI, 0.26-0.77).

For patients without AF, apixaban was again associated with a lower risk of major bleeding versus warfarin and versus rivaroxaban, while rivaroxaban was associated with lower intracranial bleeding risk versus warfarin, and apixaban with lower risks for gastrointestinal bleeds.

Compared with apixaban, rivaroxaban and dabigatran were associated with higher risks of certain bleeding events, further analyses show.

Rivaroxaban and lower-dose apixaban were both associated with increased all-cause mortality risk versus warfarin, both in the atrial fibrillation and non-AF groups, Ms. Vinogradova and her coinvestigators noted.

“A greater proportion of the older patients on apixaban and rivaroxaban may have died while still taking anticoagulants but from age-related causes other than ischemic stroke or venous thromboembolism,” they wrote.

Compared with patients on higher doses of DOACs, patients receiving lower doses were older and had more comorbidities and more previous events, they added.

Between DOACs, results of this particular analysis were most favorable for apixaban, according to investigators.

“Our study has shown that the risk of major bleeding is lower in patients taking apixaban regardless of the reason for prescribing,” they wrote. “This was most pronounced for intracranial bleeding in patients with atrial fibrillation and for gastrointestinal bleeding in patients without atrial fibrillation, appearing, in general, to show apixaban to be the safest drug.”

The study was supported by a grant from the National Institute for Health Research. The investigators had no relevant disclosures.
