Biosimilars and patients: Discussions should address safety, cost, and anxiety about change

Rheumatologist Marcus Snow, MD, is comfortable with prescribing biosimilars as a first-line, first-time biologic, and discussing them with patients.

“If a biosimilar is on the market, it has gone through rigorous study proving its effectiveness and equivalence to a bio-originator,” said Dr. Snow, a rheumatologist with the University of Nebraska Medical Center, Omaha, and chair of the American College of Rheumatology’s Committee on Rheumatologic Care.

The formulary makes a big difference in the conversation about options, he said. “The formularies dictate what we can prescribe. It may not be appropriate, but it is reality. The cost of biologics for a patient without insurance coverage makes it impossible to afford.”

He will often tell patients that he’ll fight any changes or formulary restrictions he does not agree with. “However, when I see patients in follow-up, even if there is no known change on the horizon, I may bring up biosimilars when we have a moment to chat about them to familiarize them with what may happen in the future.”

The need for patient education on biosimilars presents a barrier to realizing their potential to save money and expand choice, noted Cardinal Health in its 2023 biosimilars report. Of 103 rheumatologists who responded to a Cardinal Health survey, 85% agreed that patient education was important. But those conversations can take an uncomfortable turn if the patient pushes back against taking a biosimilar owing to cost or safety concerns.

It’s not uncommon for a patient to express some anxiety about biosimilars, especially if they’re doing well on a current treatment plan. Most patients do not want any changes that may lead to worsening disease control, Dr. Snow said.

Patients and physicians alike often don’t understand the mechanics of biosimilars. “There’s a lot of misinformation about this,” said Sameer Awsare, MD, an associate executive director for The Permanente Medical Group in Campbell, Calif. Patients should know that a biosimilar will be as clinically efficacious as the medicine they’ve been on, with the same safety profiles, said Dr. Awsare, who works with Kaiser Permanente’s pharmacy partners on biosimilars.
 

Insurance often drives the conversation

The global anti-inflammatory biologics market is anticipated to reach $150 billion by 2027, according to a recent CVS report. As of March 2023, the Food and Drug Administration had approved 40 biosimilars to 11 different reference products. There are 28 on the U.S. market and 100 more in development. Projected to save more than $180 billion over the next 5 years, they are anticipated to expand choice and drive competition.

Rheumatologists, dermatologists, and gastroenterologists are frequent prescribers, although their choices for immune-mediated inflammatory diseases are limited to tumor necrosis factor inhibitors (infliximab [Remicade] originator and adalimumab [Humira] originator) and anti-CD20 agents, such as rituximab (Rituxan) originator.

Benefit design or formulary usually dictates what medicine a patient receives. “Because of significantly higher out-of-pocket cost or formulary positioning, patients may end up with a generic or a biosimilar instead of a brand-name medicine or branded biologic,” said Robert Popovian, PharmD, MS, chief science policy officer of the Global Healthy Living Foundation.

Insurers rarely offer both Remicade and biosimilar infliximab, allowing the doctor to choose, said Miguel Regueiro, MD, chair of the Cleveland Clinic’s Digestive Disease & Surgery Institute, who prescribes infliximab biosimilars. Most often, the payer will choose the lower-cost biosimilar. “I am fine with the biosimilar, either as a new start or a switch from the reference product.”

Dr. Miguel Regueiro

However, the patient might feel differently. They can form an attachment to the reference medication if it has prevented severe illness. “They do not want to change, as they feel they are going on a ‘new’ medication that will not work as well,” Dr. Regueiro said.

This is where the education comes in: to reassure patients that a biosimilar will work just as well as the reference product. “For patients who have done well for years on a biologic, more time needs to be spent reassuring them and answering questions,” compared with a patient just starting on a biosimilar, he advised.

But not all physicians are quick to prescribe biosimilars.

Especially with psoriasis, which has so many strong options for reference drugs, a switch may be hard to justify, said dermatologist Stephanie K. Fabbro, MD, assistant professor at Northeast Ohio Medical University, Rootstown. “If I have a preference, I would rather switch a patient to a drug from a different class without a biosimilar option to reduce the possibility of pushback.”

Dr. Fabbro, part of the core faculty in the Riverside Methodist Hospital Dermatology Residency Program in Columbus, will share data from clinical trials and postmarket surveillance with patients to support her decision.
 

 

 

Conversations about cost

Patients may also push back if they don’t save money when switching to a biosimilar. “This dilemma raises the question of who is profiting when a biosimilar is dispensed,” Dr. Popovian said. Insurers and pharmacy benefit managers (PBMs) that take additional concessions from biopharmaceutical manufacturers in the form of rebates and fees will often pocket this money as profit instead of passing savings back to the patient to help reduce their out-of-pocket requirement, he added.

If an originator biologic and a biosimilar are available, “as a pharmacist, I will choose the medicine that will incur the lowest out-of-pocket cost for the patient,” Dr. Popovian said.

Dr. Vivek Kaul

Discussing cost – and who dictates which biosimilar is on the formulary – is an important conversation to have with patients, said Vivek Kaul, MD, Segal-Watson Professor of Medicine at the University of Rochester (N.Y.) Medical Center.

Providing equivalent clinical efficacy while saving costs is the economic reality of biosimilars, Dr. Kaul said. Third-party payers regularly evaluate how to provide the same quality of care while saving money. Physicians and patients alike “must be mindful that as time goes on, if the science on biosimilars stays robust, if the adoption is more widespread and the cost-saving proposition turns out to be true, more formularies will be attracted to replacing the reference product with the biosimilar counterpart.”

Providers and patients can weigh the options if a formulary suddenly switches to a biosimilar, Dr. Kaul continued. “You can accept the novel product on the formulary or may have to face out-of-pocket expenses as a patient.” If providers and patients have concerns about the biosimilar, they can always appeal if there’s solid scientific evidence that supports reverting back to the reference product.



“If you think the biosimilar is equally efficacious, comes at a lower cost, and is right for the patient, then the providers should tell the patient that,” he added.

Some studies have questioned whether the biosimilars will save money, compared with the reference drug, Dr. Fabbro noted. Medicare, for example, may pay only for a certain percentage of an approved biosimilar, saddling the patient with a monthly copay costing thousands of dollars. “It is unclear whether biosimilar manufacturers will have the same level of patient support programs as the reference drug companies.”

For that reason, physicians should also inform patients about the robust patient assistance and copay assistance programs many reference drug manufacturers offer, she said.

Biosimilars 101: Familiarizing patients

Safety and ease of use are other common concerns about biosimilars. Patients may ask if the application is different, or why it’s advantageous to switch to a biosimilar, Dr. Awsare said.

Sometimes the syringe or injector for a biosimilar might look different from that of the originator drug, he said.

Anecdotally, Dr. Fabbro has heard stories of patients having injection reactions that they did not experience with the reference drug or having a disease flare-up after starting a biosimilar.

As is the case with reference products, in their conversations with patients, clinicians should address the adverse event profile of biosimilars, offering data points from published studies and clinical guidelines that support the use of these products. “There should be an emphasis on patient education around efficacy and any side effects, and how the profile of the reference product compares with a proposed biosimilar,” Dr. Kaul suggested.

When Dr. Snow discusses biosimilars and generics, “I make sure to share this in an understandable way based on the patient’s scientific background, or lack thereof,” he said. If there is enough time, he also discusses how European- and U.S.-sourced biologics are slightly different.

Pharmacists should tell patients to expect the same clinical outcomes from a biosimilar, Dr. Popovian said. However, if they have any reduction in efficacy or potential safety concerns, they should communicate with their physician or pharmacist immediately.

In Dr. Regueiro’s practice, a pharmacist specializing in inflammatory bowel disease often has a one-on-one meeting with patients to educate and answer questions. “Additionally, we provide them the Crohn’s and Colitis Foundation web link on biosimilars,” said Dr. Regueiro.
 

 

 

A village approach to education

When biosimilars first came out, there were no formal education materials, Dr. Awsare said. Kaiser Permanente decided to create its own educational materials, not just for patients but also to help educate its primary care doctors; the rheumatologists, dermatologists, and gastroenterologists using the biosimilars; the nurses infusing patients; and the pharmacists preparing the biosimilars.

The health system also has a different approach to choosing medication. Instead of having an insurance company or PBM decide what’s in the formulary, clinicians work with the pharmacists at Kaiser to look at clinical evidence and decide which biosimilar to use. Most of its plans also provide lower copays to patients when they use the biosimilar. 

This was the approach for Humira biosimilars, Dr. Awsare said. Eight will be on the market in 2023. “Our rheumatologists, dermatologists, and gastroenterologists looked at the data from Europe, looked at some real-world evidence, and then said: ‘We think this one’s going to be the best one for our patients.’ ”

Having clinicians choose the biosimilar instead of a health plan makes it a lot easier to have conversations with patients, he said. “Once we’ve moved that market share to that particular biosimilar, we give our physicians the time to have those discussions.”

Clinical pharmacists also provide educational support, offering guidance on issues such as side effects, as patients transition to the biosimilar. “We like to use the word ‘transition’ because it’s essentially the same biologic. So, you’re not actually switching,” Dr. Awsare said.

No consensus on interchangeability

Whether the conversation on interchangeability will affect patient conversations with physicians depends on who you ask.

If a biosimilar has an interchangeability designation, it means that the pharmacist can substitute it without the intervention of the clinician who prescribed the reference product. It does not relate to the quality, safety, or effectiveness of biosimilars or interchangeable biosimilar products, Dr. Popovian said.

The United States is the only country that has this designation. Even though it’s not identical to the originator drug, a biosimilar has the same clinical efficacy and safety profile. “So clinically, interchangeability is meaningless,” Dr. Awsare said.

In its report on biosimilars in the autoimmune category, CVS acknowledged that interchangeability was important but would not be a significant factor in driving adoption of biosimilars. However, in a Cardinal Health survey of 72 gastroenterologists, 38% cited the interchangeability of biosimilars as a top concern for adalimumab biosimilars, along with transitioning patients from Humira to a biosimilar (44%).

“Patient education regarding biosimilar safety, efficacy, and interchangeability appears paramount to the acceptance of these products, particularly for patients who are switched from a reference product,” Dr. Kaul noted in the Cardinal Health report.

Wherever supported by data, Dr. Kaul recommends incorporating biosimilar use and interchangeability into best practice guidelines going forward. “That will go a long way in disseminating the latest information on this topic and position this paradigm for increased adoption among providers.”

Some physicians like Dr. Snow aren’t that concerned with interchangeability. This hasn’t affected conversations with patients, he said. Multiple studies demonstrating the lack of antibody formation with multiple switches from different biosimilar drugs has eased his concern about multiple switches causing problems.

“Initially, there was a gap in demonstrating the long-term effect of multiple switches on antibody production and drug effectiveness. That gap has started to close as more data from Europe’s experience with biosimilars becomes available,” Dr. Snow said.
 

 

 

Resources for physicians, patients

The federal government has taken steps to advance biosimilars education and adoption. In 2021, President Biden signed the Advancing Education on Biosimilars Act into law, which directs the FDA to develop or improve continuing education programs that address prescribing of biosimilars and biological products.

The FDA provides educational materials on its website, including a comprehensive curriculum toolkit. The Accreditation Council for Medical Affairs has also created an online 40-hour curriculum for health care professionals called the Board-Certified Biologics and Biosimilars Specialist Program.

Dr. Fabbro recommended patients use the FDA page Biosimilar Basics for Patients to educate themselves on biosimilars. The Global Healthy Living Foundation’s podcast, Breaking Down Biosimilars, is another free resource for patients.

“While much has changed, the continued need for multistakeholder education, awareness, and dedicated research remains even more important as we expand into newer therapeutic areas and classes,” wrote the authors of the Cardinal Health report.

Physicians and patients alike “must be mindful that as time goes on, if the science on biosimilars stays robust, if the adoption is more widespread and the cost-saving proposition turns out to be true, more formularies will be attracted to replacing the reference product with the biosimilar counterpart.”

Providers and patients can weigh the options if a formulary suddenly switches to a biosimilar, Dr. Kaul continued. “You can accept the novel product on the formulary or may have to face out-of-pocket expenses as a patient.” If providers and patients have concerns about the biosimilar, they can always appeal if there’s solid scientific evidence that supports reverting back to the reference product.



“If you think the biosimilar is equally efficacious, comes at a lower cost, and is right for the patient, then the providers should tell the patient that,” he added.

Some studies have questioned whether the biosimilars will save money, compared with the reference drug, Dr. Fabbro noted. Medicare, for example, may pay only for a certain percentage of an approved biosimilar, saddling the patient with a monthly copay costing thousands of dollars. “It is unclear whether biosimilar manufacturers will have the same level of patient support programs as the reference drug companies.”

For that reason, physicians should also inform patients about the robust patient assistance and copay assistance programs many reference drug manufacturers offer, she said.

Biosimilars 101: Familiarizing patients

Safety and ease of use are other common concerns about biosimilars. Patients may ask if the application is different, or why it’s advantageous to switch to a biosimilar, Dr. Awsare said.

Sometimes the syringe or injector for a biosimilar might look different from that of the originator drug, he said.

Anecdotally, Dr. Fabbro has heard stories of patients having injection reactions that they did not experience with the reference drug or having a disease flare-up after starting a biosimilar.

As is the case with reference products, in their conversations with patients, clinicians should address the adverse event profile of biosimilars, offering data points from published studies and clinical guidelines that support the use of these products. “There should be an emphasis on patient education around efficacy and any side effects, and how the profile of the reference product compares with a proposed biosimilar,” Dr. Kaul suggested.

When Dr. Snow discusses biosimilars and generics, “I make sure to share this in an understandable way based on the patient’s scientific background, or lack thereof,” he said. If there is enough time, he also discusses how European- and U.S.-sourced biologics are slightly different.

Pharmacists should tell patients to expect the same clinical outcomes from a biosimilar, Dr. Popovian said. However, if they have any reduction in efficacy or potential safety concerns, they should communicate with their physician or pharmacist immediately.

In Dr. Regueiro’s practice, a pharmacist specializing in inflammatory bowel disease often has a one-on-one meeting with patients to educate and answer questions. “Additionally, we provide them the Crohn’s and Colitis Foundation web link on biosimilars,” said Dr. Regueiro.
 

 

 

A village approach to education

When biosimilars first came out, there were no formal education materials, Dr. Awsare said. Kaiser Permanente decided to create its own educational materials, not just for patients but also to help educate its primary care doctors; the rheumatologists, dermatologists, and gastroenterologists using the biosimilars; the nurses infusing patients; and the pharmacists preparing the biosimilars.

The health system also has a different approach to choosing medication. Instead of having an insurance company or PBM decide what’s in the formulary, clinicians work with the pharmacists at Kaiser to look at clinical evidence and decide which biosimilar to use. Most of its plans also provide lower copays to patients when they use the biosimilar. 

This was the approach for Humira biosimilars, Dr. Awsare said. Eight will be on the market in 2023. “Our rheumatologists, dermatologists, and gastroenterologists looked at the data from Europe, looked at some real-world evidence, and then said: ‘We think this one’s going to be the best one for our patients.’ ”

Having clinicians choose the biosimilar instead of a health plan makes it a lot easier to have conversations with patients, he said. “Once we’ve moved that market share to that particular biosimilar, we give our physicians the time to have those discussions.”

Clinical pharmacists also provide educational support, offering guidance on issues such as side effects, as patients transition to the biosimilar. “We like to use the word ‘transition’ because it’s essentially the same biologic. So, you’re not actually switching,” Dr. Awsare said.

No consensus on interchangeability

Whether the conversation on interchangeability will affect patient conversations with physicians depends on who you ask.

If a biosimilar has an interchangeability designation, it means that the pharmacist can substitute it without the intervention of the clinician who prescribed the reference product. It does not relate to the quality, safety, or effectiveness of biosimilars or interchangeable biosimilar products, Dr. Popovian said.

The United States is the only country that has this designation. Even though it’s not identical to the originator drug, a biosimilar has the same clinical efficacy and safety profile. “So clinically, interchangeability is meaningless,” Dr. Awsare said.

In its report on biosimilars in the autoimmune category, CVS acknowledged that interchangeability was important but would not be a significant factor in driving adoption of biosimilars. However, in a Cardinal Health survey of 72 gastroenterologists, 38% cited the interchangeability of biosimilars as a top concern for adalimumab biosimilars, along with transitioning patients from Humira to a biosimilar (44%).

“Patient education regarding biosimilar safety, efficacy, and interchangeability appears paramount to the acceptance of these products, particularly for patients who are switched from a reference product,” Dr. Kaul noted in the Cardinal Health report.

Wherever supported by data, Dr. Kaul recommends incorporating biosimilar use and interchangeability into best practice guidelines going forward. “That will go a long way in disseminating the latest information on this topic and position this paradigm for increased adoption among providers.”

Some physicians like Dr. Snow aren’t that concerned with interchangeability. This hasn’t affected conversations with patients, he said. Multiple studies demonstrating the lack of antibody formation with multiple switches from different biosimilar drugs has eased his concern about multiple switches causing problems.

“Initially, there was a gap in demonstrating the long-term effect of multiple switches on antibody production and drug effectiveness. That gap has started to close as more data from Europe’s experience with biosimilars becomes available,” Dr. Snow said.
 

 

 

Resources for physicians, patients

The federal government has taken steps to advance biosimilars education and adoption. In 2021, President Biden signed the Advancing Education on Biosimilars Act into law, which directs the FDA to develop or improve continuing education programs that address prescribing of biosimilars and biological products.

The FDA provides educational materials on its website, including a comprehensive curriculum toolkit. The Accreditation Council for Medical Affairs has also created an online 40-hour curriculum for health care professionals called the Board-Certified Biologics and Biosimilars Specialist Program.

Dr. Fabbro recommended patients use the FDA page Biosimilar Basics for Patients to educate themselves on biosimilars. The Global Healthy Living Foundation’s podcast, Breaking Down Biosimilars, is another free resource for patients.

“While much has changed, the continued need for multistakeholder education, awareness, and dedicated research remains even more important as we expand into newer therapeutic areas and classes,” wrote the authors of the Cardinal Health report.

Help patients understand biologics and biosimilars by using AGA resources for providers and patients available at gastro.org/biosimilars.

Meta-analysis compares efficacy of lasmiditan, rimegepant, and ubrogepant for acute treatment of migraine

Article Type
Changed

Key clinical point: Lasmiditan, rimegepant, and ubrogepant demonstrated superior efficacy over placebo for the acute treatment of migraine attacks, with lasmiditan being the most effective at high doses but with higher odds of adverse events.

 

Major finding: Compared with placebo, 200 mg lasmiditan (odds ratio [OR] 2.88; 95% CI 2.22-3.73), followed by 100 mg lasmiditan (OR 2.28; 95% CI 1.75-2.96), rimegepant (OR 2.0; 95% CI 1.45-2.75), and 100 mg ubrogepant (OR 1.97; 95% CI 1.27-3.07) were more efficacious for achieving pain freedom at 2 hours post-dose before the use of any rescue medication. However, the odds of dizziness, nausea, and somnolence were greater with all doses of lasmiditan.

 

Study details: This network meta-analysis of seven phase 3 randomized controlled trials included 12,859 patients with migraine

 

Disclosures: This study did not report the funding source. PJ Goadsby and C Tassorelli declared receiving grants or personal fees or participating in advisory boards or lecturing at symposia for various sources.

Real-world study compares benefits for patients with migraine of mAb against CGRP and its receptor

Article Type
Changed

Key clinical point: Both types of anti-calcitonin gene-related peptide (CGRP) monoclonal antibodies (mAb), those against CGRP ligand (anti-CGRP) and those against CGRP receptor (anti-CGRP-R), showed benefits as preventive treatments for migraine; however, the proportion of anti-CGRP super responders was higher.

 

Major finding: Patients receiving anti-CGRP vs anti-CGRP-R had a significantly lower Migraine Disability Assessment scale score at 1 (P = .040) and 3 (P = .048) months and mean migraine days at 3 months (P = .01). The proportion of super responders were significantly higher in the anti-CGRP vs anti-CGRP-R group at 3-month (P = .041) and 6-month (P = .047) follow-ups.

 

Study details: This retrospective observational study included 152 patients with high-frequency episodic migraine or chronic migraine, of whom 68 were treated with anti-CGRP mAbs and 84 were treated with anti-CGRP-R mAbs.

 

Disclosures: This study did not receive any specific funding. Three authors declared serving as consultants and on scientific advisory boards or receiving speaker honoraria from various sources.

Fremanezumab shows favorable benefit-risk profile in difficult-to-treat migraine

Article Type
Changed

Key clinical point: Real-world data support fremanezumab as an effective, safe, and well-tolerated treatment option in patients with difficult-to-treat migraine and multiple preventive treatment failures.

 

Major finding: Overall, 83.5% and 62.6% of patients with high-frequency episodic migraine (HFEM) and chronic migraine (CM) receiving fremanezumab achieved ≥50% reduction in monthly headache days (MHD), respectively, along with a significant improvement in mean MHD, MHD with peak headache intensity of ≤5, intake of any abortive medications, migraine-related disability, and quality of life (all P < .001). Only 36 cases of mild adverse events were reported.

 

Study details: This open-label, single-arm, prospective, multicenter, clinical study included 204 patients with HFEM (n = 97) or CM (n = 107) who received 3 monthly courses of fremanezumab.

 

Disclosures: This study did not receive any funding. Some authors declared receiving investigator fees or travel grants from, or serving as consultants or advisory board members for various sources.

Migraine: Identifying clinical traits of super-responders vs non-responders to CGRP-R mAb

Article Type
Changed

Key clinical point: Clinical characteristics differed significantly among patients with migraine who experienced ≥75% (super-responders [SR]) vs ≤25% (non-responders [NR]) reduction in monthly headache days in the third month after initiating prophylactic treatment with calcitonin gene-related peptide receptor (CGRP-R) monoclonal antibodies (mAb).

 

Major finding: SR vs NR were more likely to report vomiting (P = .031) and a significant improvement in acute migraine headache with triptan treatment (P = .010). However, NR vs SR experienced chronic migraine (P = .001), medication overuse headache (P = .024), and concomitant depression (P = .005) more frequently.

 

Study details: This was a retrospective real-world study including 260 patients with migraine who received 1 treatment with CGRP-R mAbs for migraine prevention, of which 29 and 26 were SR and NR, respectively.

 

Disclosures: This study did not report the source of funding. Four authors declared receiving research grants, personal fees, or honoraria for consulting and lectures from various sources.

Traumatic brain injury raises risk for subsequent migraine

Article Type
Changed

Key clinical point: Patients with traumatic brain injury (TBI) were at a significantly higher risk for subsequent migraine, with the risk being even higher among patients with TBI who were hospitalized and those who had a major trauma.

 

Major finding: The risk for migraine was significantly higher among patients with vs without TBI (adjusted hazard ratio [aHR] 1.484), with migraine incidence being higher after major vs minor trauma (aHR 1.670) and among hospitalized patients vs patients visiting the outpatient department (aHR 1.557; all P < .001).

 

Study details: This retrospective cohort study included 151,098 patients with newly diagnosed TBI and 604,394 propensity score-matched patients without TBI.

 

Disclosures: This study was supported by the National Science and Technology Council of the Republic of China, Cardinal Tien Hospital, and Tri-Service General Hospital Research Foundation. The authors declared no conflicts of interest.

Benign paroxysmal positional vertigo associated with higher risk for migraine

Article Type
Changed

Key clinical point: Patients with benign paroxysmal positional vertigo (BPPV) are at a higher risk for migraine diagnosis, with female sex, hyperlipidemia, and anxiety being significant risk factors for migraine among patients with BPPV.

 

Major finding: In 11 years of follow-up, 1.35% vs 0.41% of participants with vs without BPPV had migraine, respectively. The risk for migraine was 2.96-fold higher among those with BPPV (adjusted hazard ratio [aHR] 2.96; 95% CI 2.30-3.80; P < .001) and significantly higher among women (aHR 2.91; 95% CI 2.30-3.80), those with hyperlipidemia (aHR 1.77; 95% CI 1.16-2.70), and those with anxiety (aHR 1.49; 95% CI 1.03-2.14).

 

Study details: Findings are from a retrospective cohort study including 1386 patients with BPPV and 5544 age- and sex-matched control individuals without a history of BPPV or migraine.

 

Disclosures: This study did not receive any external funding. The authors declared no conflicts of interest.

Real-world study: Predictors of poor response to galcanezumab in chronic migraine

Article Type
Changed

Key clinical point: About two-thirds of patients with chronic migraine (CM) showed response to galcanezumab, and everyday headache, presence of depression, and absence of accompanying symptoms were independent predictors of a poor response to galcanezumab treatment.

 

Major finding: After 3 months, 64.3% of patients receiving galcanezumab achieved ≥50% reduction in monthly migraine days, with everyday headache (odds ratio [OR] 0.351; P = .017), presence of depression (OR 0.439; P = .024), and absence of accompanying symptoms (OR 0.314; P = .020) being significant predictors of response to galcanezumab.

 

Study details: The data come from a real-world, prospective observational study including 238 patients aged ≥18 years with CM who received preventive treatment with galcanezumab injections for 3 months.

 

Disclosures: This study did not report the source of funding. BK Kim declared receiving honoraria and personal fees, serving on advisory boards, and being a principal investigator of trials sponsored by various sources.

Galcanezumab improves interictal burden in patients with migraine with multiple treatment failures

Article Type
Changed

Key clinical point: Galcanezumab significantly reduced interictal burden, as measured by the 4-item Migraine Interictal Burden Scale (MIBS-4), in patients with episodic or chronic migraine and multiple prior migraine preventive treatment failures.

 

Major finding: At 3 months, the mean MIBS-4 score reduced significantly with galcanezumab vs placebo in the overall population (least-squares mean change [Δ] −1.9 vs −0.8; P < .0001) and in patients with episodic −1.8 vs −1.1; P = .033) and chronic (Δ −1.8 vs −0.3; P < .001) migraine.

 

Study details: This was a post hoc analysis of the CONQUER study including 462 patients with chronic or episodic migraine and multiple prior migraine preventive treatment failures who were randomly assigned to receive galcanezumab or placebo.

 

Disclosures: This study was funded by Eli Lilly and Company. Some authors declared receiving research funding or support from various pharmaceutical sources, including Eli Lilly and Company. Some others declared being employees and minor stockholders of Eli Lilly and Company.

CGRP monoclonal antibodies and gepants: Safe and well-tolerated options for migraine prevention

Article Type
Changed

Key clinical point: Network meta-analysis confirms the overall safety of anti-calcitonin gene-related peptide (CGRP) monoclonal antibodies and gepants for migraine prevention, with rare instances of treatment discontinuation.

 

Major finding: The risk for serious adverse events was not significantly different with active treatments and placebo, with 30 mg eptinezumab being the only treatment significantly associated with higher odds of adverse events leading to treatment discontinuation (odds ratio [OR] 2.62; 95% CI 1.03-6.66). Compared with placebo, the risk for treatment-emergent adverse events was not significantly different with 30 mg and 100 mg eptinezumab and was the highest with 240 mg galcanezumab (OR 1.63; 95% CI 1.33-2.00) and 120 mg galcanezumab (OR 1.40; 95% CI 1.16-1.70), with the most frequent being injection site erythema, induration, and pruritus.

 

Study details: The data come from a network meta-analysis of 19 phase 3 randomized controlled trials including 14,584 patients with migraine.

 

Disclosures: This study did not report the source of funding. The authors declared no conflicts of interest.
