Key clinical point: All multiple manifestations of psoriatic arthritis (PsA) negatively affect quality of life (QoL), with dactylitis, peripheral joint disease, and psoriasis impairing functional status, whereas joint, skin, and periarticular symptoms independently impair work productivity.

Major finding: Presence vs absence of enthesitis, dactylitis, inflammatory back pain, and peripheral joint involvement was associated with worse QoL and self-rated health (all P < .05), whereas increasing number of affected joints and greater body surface area involvement significantly correlated with poorer functional state and greater work productivity impairment (all P < .05).

Study details: Findings are from a cross-sectional observational study including 2222 patients with physician-confirmed diagnosis of PsA.

Disclosures: This study did not receive any specific funding. Some authors declared receiving grants from, serving as a consultant for, being an employee of, or owning shares in different sources.

PEMAZYRE® (pemigatinib) is indicated for the treatment of adults with previously treated, unresectable locally advanced or metastatic cholangiocarcinoma with a fibroblast growth factor receptor 2 (FGFR2) fusion or other rearrangement as detected by an FDA-approved test. This indication is approved under accelerated approval based on overall response rate and duration of response. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial(s)¹. 

PEMAZYRE can cause serious adverse reactions including Ocular Toxicity (Retinal Pigment Epithelial Detachment [RPED] and Dry Eye), Hyperphosphatemia and Soft Tissue Mineralization, and Embryo-Fetal Toxicity. See Additional Important Safety Information Below¹.

Cholangiocarcinoma, or CCA, is a rare cancer formed in the bile duct. It is difficult to diagnose due to generalized symptoms patients often experience². As with any serious disease, the initial diagnosis can be an incredibly overwhelming experience for patients and their families. For people living with CCA specifically, the diagnosis process can be very long and arduous, which often means a patient’s condition can reach an advanced stage where the prognosis is poor by the time he or she is diagnosed³.

Scientific advancements, such as biomarker testing, or genomic analysis of a patient’s tissue, have made it possible to better understand a person’s specific cancer. Understanding patients’ tumors at the molecular level may help health care professionals individualize a treatment plan that is specific to each patient. 

As the genomic profile of CCA has become clearer, actionable alterations in the DNA that are amenable to treatment with either existing agents or those in development have come into focus. Certain actionable genomic alterations have been identified in up to 2/3 of patients with the intrahepatic subtype of CCA, although this percentage may vary in actual practice⁴. Specifically, research has found that fibroblast growth factor receptor 2 (FGFR2) alterations, which play an important role in the development of cancers like CCA, especially the intrahepatic subtype, is on the rise³. This has prompted recognition of comprehensive genomic testing. Due to the rapid advances in precision medicine for CCA, the NCCN guidelines recommend the use of biomarker testing for advanced CCA⁵. 

The First Targeted Treatment Option for CCA

Though an incredibly useful tool, there is a need for further education about the importance of early biomarker testing amongst the medical community. In one large community-based hospital in California, the implementation of a precision medicine program allowed oncologists and pathologists to standardize all tumor biomarker testing, resulting in an increase in testing⁵. However, there is still much improvement needed. What’s more, scientific advancements in recent years have opened the door to targeted treatment options including Pemazyre® (pemigatinib). Pemazyre was approved by the U.S. Food and Drug Administration (FDA) under accelerated approval in 2020 as the first targeted treatment for adults with previously treated, unresectable locally advanced or metastatic CCA with a FGFR2 fusion or other rearrangement as detected by an FDA-approved test.

“The FDA approval of Pemazyre was and continues to be an encouraging milestone for the CCA community, as patients historically had limited options after first-line chemotherapy or surgery, after which relapse rates were high,” said Dr. Sahai.

Pemazyre works by helping to stop the activity of the abnormal FGFR2 protein, which may help reduce the size of CCA tumors or cause them to disappear. Pemazyre’s approval was based on the results of the multicenter, open-label, single arm FIGHT-202 study in 146 previously treated patients with locally advanced or metastatic CCA1. 

• The efficacy population consisted of 107 patients with disease that had progressed on or after at least 1 prior therapy and who had an FGFR2 fusion or non-fusion rearrangement, as determined by a clinical trial assay (FoundationOne® CDx) performed at a central laboratory.
• The major efficacy outcome measures were overall response rate (ORR) and duration of response (DoR). The study found an ORR of 36%, and median DoR of 9.1 months. 
• The most common adverse reactions (incidence ≥20%) in all patients were hyperphosphatemia, alopecia, diarrhea, nail toxicity, fatigue, dysgeusia, nausea, constipation, stomatitis, dry eye, dry mouth, decreased appetite, vomiting, arthralgia, abdominal pain, hypophosphatemia, back pain, and dry skin.

Meet Fred, Battling CCA

Meet Fred – a man living with CCA. After noticing an unusual amount of blood following what he thought was a normal kidney stone, Fred contacted his doctor right away. Unfortunately, it was not clear from his initial symptoms what the problem was. A computed tomography (CT or CAT) scan revealed Fred did indeed have a kidney stone, but it also showed a large mass had formed on his liver, leading to more testing. After several tests, Fred was diagnosed with CCA. Because of the nonspecific symptoms he had been experiencing, his cancer unfortunately had time to grow. Upon advice from his doctor, Fred met with a CCA specialist who quickly ordered biomarker testing, revealing that he had FGFR2-driven CCA. With a molecular understanding of Fred’s specific CCA, his health care team was able to prescribe him Pemazyre. 

“I’m grateful I was able to start receiving treatment for my condition following chemotherapy and continue to see improvements in my condition,” noted Fred. “Though I fight side effects such as great fatigue, dry eye, dry skin, and fingernail discoloration, these innovations in science that lead to treatments like Pemazyre are what continue to give my family and I hope.”

Through his own experience, Fred has become an advocate for encouraging others living with CCA to educate themselves about the disease and the importance of early biomarker testing. “My advice is to be your own health advocate. Take charge of how your diagnosis and treatment plan is formed with your doctor, and don’t be afraid to speak openly with your doctor about the tools, like biomarker testing, that are available,” said Fred. “I feel fortunate that my health care team initiated biomarker testing quickly after my diagnosis, which enabled me to find an appropriate treatment option for my specific condition. I know that’s not always the case for my fellow CCA warriors, so I urge those in the community to take charge of their health conversations.” 

Leverage The Leading Tools at Hand 

Fred’s story, like that of so many other CCA patients, was a long and winding road to an accurate diagnosis; however, once he was diagnosed, biomarker testing allowed for Fred’s health care team to fully understand his condition, which led to a tailored treatment plan with Pemazyre. While the regular use of biomarker testing is on the rise, it’s critical that health care providers continue to institute early biomarker testing as standard practice, as it may provide the opportunity to quickly and accurately determine the best path forward for their patients.

This indication is approved under accelerated approval based on overall response rate and duration of response. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial(s).

IMPORTANT SAFETY INFORMATION

Ocular Toxicity
Retinal Pigment Epithelial Detachment (RPED): PEMAZYRE can cause RPED, which may cause symptoms such as blurred vision, visual floaters, or photopsia. Clinical trials of PEMAZYRE did not conduct routine monitoring including optical coherence tomography (OCT) to detect asymptomatic RPED; therefore, the incidence of asymptomatic RPED with PEMAZYRE is unknown.

Among 635 patients who received a starting dose of PEMAZYRE 13.5 mg across clinical trials, RPED occurred in 11% of patients, including Grade 3-4 RPED in 1.3%. The median time to first onset of RPED was 56 days. RPED led to dose interruption of PEMAZYRE in 3.1% of patients, and dose reduction and permanent discontinuation in 1.3% and in 0.2% of patients, respectively. RPED resolved or improved to Grade 1 levels in 76% of patients who required dosage modification of PEMAZYRE for RPED.

Perform a comprehensive ophthalmological examination including OCT prior to initiation of PEMAZYRE and every 2 months for the first 6 months and every 3 months thereafter during treatment. For onset of visual symptoms, refer patients for ophthalmologic evaluation urgently, with follow-up every 3 weeks until resolution or discontinuation of PEMAZYRE. Modify the dose or permanently discontinue PEMAZYRE as recommended in the prescribing information for PEMAZYRE. 

Dry Eye:  Among 635 patients who received a starting dose of PEMAZYRE 13.5 mg across clinical trials, dry eye occurred in 31% of patients, including Grade 3-4 in 1.6% of patients. Treat patients with ocular demulcents as needed.

Hyperphosphatemia and Soft Tissue Mineralization
PEMAZYRE can cause hyperphosphatemia leading to soft tissue mineralization, cutaneous calcification, calcinosis, and non-uremic calciphylaxis. Increases in phosphate levels are a pharmacodynamic effect of PEMAZYRE. Among 635 patients who received a starting dose of PEMAZYRE 13.5 mg across clinical trials, hyperphosphatemia was reported in 93% of patients based on laboratory values above the upper limit of normal. The median time to onset of hyperphosphatemia was 8 days (range 1-169). Phosphate lowering therapy was required in 33% of patients receiving PEMAZYRE.

Monitor for hyperphosphatemia and initiate a low phosphate diet when serum phosphate level is >5.5 mg/dL. For serum phosphate levels >7 mg/dL, initiate phosphate lowering therapy and withhold, reduce the dose, or permanently discontinue PEMAZYRE based on duration and severity of hyperphosphatemia as recommended in the prescribing information.

Embryo-Fetal Toxicity
Based on findings in an animal study and its mechanism of action, PEMAZYRE can cause fetal harm when administered to a pregnant woman. Oral administration of pemigatinib to pregnant rats during the period of organogenesis caused fetal malformations, fetal growth retardation, and embryo-fetal death at maternal exposures lower than the human exposure based on area under the curve (AUC) at the clinical dose of 13.5 mg.

Advise pregnant women of the potential risk to the fetus. Advise female patients of reproductive potential to use effective contraception during treatment with PEMAZYRE and for 1 week after the last dose. Advise males with female partners of reproductive potential to use effective contraception during treatment with PEMAZYRE and for 1 week after the last dose.

Adverse Reactions:  Cholangiocarcinoma
Serious adverse reactions occurred in 45% of patients receiving PEMAZYRE (n=146). Serious adverse reactions in ≥2% of patients who received PEMAZYRE included abdominal pain, pyrexia, cholangitis, pleural effusion, acute kidney injury, cholangitis infective, failure to thrive, hypercalcemia, hyponatremia, small intestinal obstruction, and urinary tract infection. Fatal adverse reactions occurred in 4.1% of patients, including failure to thrive, bile duct obstruction, cholangitis, sepsis, and pleural effusion.

Permanent discontinuation due to an adverse reaction occurred in 9% of patients who received PEMAZYRE. Adverse reactions requiring permanent discontinuation in ≥1% of patients included intestinal obstruction and acute kidney injury.

Dosage interruptions due to an adverse reaction occurred in 43% of patients who received PEMAZYRE.  Adverse reactions requiring dosage interruption in ≥1% of patients included stomatitis, palmar-plantar erythrodysesthesia syndrome, arthralgia, fatigue, abdominal pain, AST increased, asthenia, pyrexia, ALT increased, cholangitis, small intestinal obstruction, alkaline phosphatase increased, diarrhea, hyperbilirubinemia, electrocardiogram QT prolonged, decreased appetite, dehydration, hypercalcemia, hyperphosphatemia, hypophosphatemia, back pain, pain in extremity, syncope, acute kidney injury, onychomadesis, and hypotension.

Dose reductions due to an adverse reaction occurred in 14% of patients who received PEMAZYRE.  Adverse reactions requiring dosage reductions in ≥1% of patients who received PEMAZYRE included stomatitis, arthralgia, palmar-plantar erythrodysesthesia syndrome, asthenia, and onychomadesis.

Clinically relevant adverse reactions occurring in ≤10% of patients included fractures (2.1%). In all patients treated with pemigatinib, 0.5% experienced pathologic fractures (which included patients with and without cholangiocarcinoma [N = 635]). Soft tissue mineralization, including cutaneous calcification, calcinosis, and non-uremic calciphylaxis associated with hyperphosphatemia were observed with PEMAZYRE treatment.

Within the first 21-day cycle of PEMAZYRE dosing, serum creatinine increased (mean increase of 0.2 mg/dL) and reached steady state by Day 8, and then decreased during the 7 days off therapy. Consider alternative markers of renal function if persistent elevations in serum creatinine are observed.

In cholangiocarcinoma (n=146) the most common adverse reactions (incidence ≥20%) were hyperphosphatemia (60%), alopecia (49%), diarrhea (47%), nail toxicity (43%), fatigue (42%), dysgeusia (40%), nausea (40%), constipation (35%), stomatitis (35%), dry eye (35%), dry mouth (34%), decreased appetite (33%), vomiting (27%), arthralgia (25%), abdominal pain (23%), hypophosphatemia (23%), back pain (20%), and dry skin (20%).

Drug Interactions
Avoid concomitant use of strong and moderate CYP3A inhibitors with PEMAZYRE. Reduce the dose of PEMAZYRE if concomitant use with a strong or moderate CYP3A inhibitor cannot be avoided. Avoid concomitant use of strong and moderate CYP3A inducers with PEMAZYRE.  
Special Populations
Advise lactating women not to breastfeed during treatment with PEMAZYRE and for 1 week after the last dose.

Cholangiocarcinoma, or CCA, is a rare cancer formed in the bile duct. It is difficult to diagnose due to generalized symptoms patients often experience². As with any serious disease, the initial diagnosis can be an incredibly overwhelming experience for patients and their families. For people living with CCA specifically, the diagnosis process can be very long and arduous, which often means a patient’s condition can reach an advanced stage where the prognosis is poor by the time he or she is diagnosed³.

Scientific advancements, such as biomarker testing, or genomic analysis of a patient’s tissue, have made it possible to better understand a person’s specific cancer. Understanding patients’ tumors at the molecular level may help health care professionals individualize a treatment plan that is specific to each patient. 

As the genomic profile of CCA has become clearer, actionable alterations in the DNA that are amenable to treatment with either existing agents or those in development have come into focus. Certain actionable genomic alterations have been identified in up to 2/3 of patients with the intrahepatic subtype of CCA, although this percentage may vary in actual practice⁴. Specifically, research has found that fibroblast growth factor receptor 2 (FGFR2) alterations, which play an important role in the development of cancers like CCA, especially the intrahepatic subtype, is on the rise³. This has prompted recognition of comprehensive genomic testing. Due to the rapid advances in precision medicine for CCA, the NCCN guidelines recommend the use of biomarker testing for advanced CCA⁵. 

The First Targeted Treatment Option for CCA

Though an incredibly useful tool, there is a need for further education about the importance of early biomarker testing amongst the medical community. In one large community-based hospital in California, the implementation of a precision medicine program allowed oncologists and pathologists to standardize all tumor biomarker testing, resulting in an increase in testing⁵. However, there is still much improvement needed. What’s more, scientific advancements in recent years have opened the door to targeted treatment options including Pemazyre® (pemigatinib). Pemazyre was approved by the U.S. Food and Drug Administration (FDA) under accelerated approval in 2020 as the first targeted treatment for adults with previously treated, unresectable locally advanced or metastatic CCA with a FGFR2 fusion or other rearrangement as detected by an FDA-approved test.

“The FDA approval of Pemazyre was and continues to be an encouraging milestone for the CCA community, as patients historically had limited options after first-line chemotherapy or surgery, after which relapse rates were high,” said Dr. Sahai.

Pemazyre works by helping to stop the activity of the abnormal FGFR2 protein, which may help reduce the size of CCA tumors or cause them to disappear. Pemazyre’s approval was based on the results of the multicenter, open-label, single arm FIGHT-202 study in 146 previously treated patients with locally advanced or metastatic CCA1. 

• The efficacy population consisted of 107 patients with disease that had progressed on or after at least 1 prior therapy and who had an FGFR2 fusion or non-fusion rearrangement, as determined by a clinical trial assay (FoundationOne® CDx) performed at a central laboratory.
• The major efficacy outcome measures were overall response rate (ORR) and duration of response (DoR). The study found an ORR of 36%, and median DoR of 9.1 months. 
• The most common adverse reactions (incidence ≥20%) in all patients were hyperphosphatemia, alopecia, diarrhea, nail toxicity, fatigue, dysgeusia, nausea, constipation, stomatitis, dry eye, dry mouth, decreased appetite, vomiting, arthralgia, abdominal pain, hypophosphatemia, back pain, and dry skin.

Meet Fred, Battling CCA

Meet Fred – a man living with CCA. After noticing an unusual amount of blood following what he thought was a normal kidney stone, Fred contacted his doctor right away. Unfortunately, it was not clear from his initial symptoms what the problem was. A computed tomography (CT or CAT) scan revealed Fred did indeed have a kidney stone, but it also showed a large mass had formed on his liver, leading to more testing. After several tests, Fred was diagnosed with CCA. Because of the nonspecific symptoms he had been experiencing, his cancer unfortunately had time to grow. Upon advice from his doctor, Fred met with a CCA specialist who quickly ordered biomarker testing, revealing that he had FGFR2-driven CCA. With a molecular understanding of Fred’s specific CCA, his health care team was able to prescribe him Pemazyre. 

“I’m grateful I was able to start receiving treatment for my condition following chemotherapy and continue to see improvements in my condition,” noted Fred. “Though I fight side effects such as great fatigue, dry eye, dry skin, and fingernail discoloration, these innovations in science that lead to treatments like Pemazyre are what continue to give my family and I hope.”

Through his own experience, Fred has become an advocate for encouraging others living with CCA to educate themselves about the disease and the importance of early biomarker testing. “My advice is to be your own health advocate. Take charge of how your diagnosis and treatment plan is formed with your doctor, and don’t be afraid to speak openly with your doctor about the tools, like biomarker testing, that are available,” said Fred. “I feel fortunate that my health care team initiated biomarker testing quickly after my diagnosis, which enabled me to find an appropriate treatment option for my specific condition. I know that’s not always the case for my fellow CCA warriors, so I urge those in the community to take charge of their health conversations.” 

Leverage The Leading Tools at Hand 

Fred’s story, like that of so many other CCA patients, was a long and winding road to an accurate diagnosis; however, once he was diagnosed, biomarker testing allowed for Fred’s health care team to fully understand his condition, which led to a tailored treatment plan with Pemazyre. While the regular use of biomarker testing is on the rise, it’s critical that health care providers continue to institute early biomarker testing as standard practice, as it may provide the opportunity to quickly and accurately determine the best path forward for their patients.

PEMAZYRE^® is indicated for the treatment of adults with previously treated, unresectable locally advanced or metastatic cholangiocarcinoma with a fibroblast growth factor receptor 2 (FGFR2) fusion or other rearrangement as detected by an FDA-approved test.

This indication is approved under accelerated approval based on overall response rate and duration of response. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial(s).

IMPORTANT SAFETY INFORMATION

Ocular Toxicity
Retinal Pigment Epithelial Detachment (RPED): PEMAZYRE can cause RPED, which may cause symptoms such as blurred vision, visual floaters, or photopsia. Clinical trials of PEMAZYRE did not conduct routine monitoring including optical coherence tomography (OCT) to detect asymptomatic RPED; therefore, the incidence of asymptomatic RPED with PEMAZYRE is unknown.

Among 635 patients who received a starting dose of PEMAZYRE 13.5 mg across clinical trials, RPED occurred in 11% of patients, including Grade 3-4 RPED in 1.3%. The median time to first onset of RPED was 56 days. RPED led to dose interruption of PEMAZYRE in 3.1% of patients, and dose reduction and permanent discontinuation in 1.3% and in 0.2% of patients, respectively. RPED resolved or improved to Grade 1 levels in 76% of patients who required dosage modification of PEMAZYRE for RPED.

Perform a comprehensive ophthalmological examination including OCT prior to initiation of PEMAZYRE and every 2 months for the first 6 months and every 3 months thereafter during treatment. For onset of visual symptoms, refer patients for ophthalmologic evaluation urgently, with follow-up every 3 weeks until resolution or discontinuation of PEMAZYRE. Modify the dose or permanently discontinue PEMAZYRE as recommended in the prescribing information for PEMAZYRE. 

Dry Eye:  Among 635 patients who received a starting dose of PEMAZYRE 13.5 mg across clinical trials, dry eye occurred in 31% of patients, including Grade 3-4 in 1.6% of patients. Treat patients with ocular demulcents as needed.

Hyperphosphatemia and Soft Tissue Mineralization
PEMAZYRE can cause hyperphosphatemia leading to soft tissue mineralization, cutaneous calcification, calcinosis, and non-uremic calciphylaxis. Increases in phosphate levels are a pharmacodynamic effect of PEMAZYRE. Among 635 patients who received a starting dose of PEMAZYRE 13.5 mg across clinical trials, hyperphosphatemia was reported in 93% of patients based on laboratory values above the upper limit of normal. The median time to onset of hyperphosphatemia was 8 days (range 1-169). Phosphate lowering therapy was required in 33% of patients receiving PEMAZYRE.

Monitor for hyperphosphatemia and initiate a low phosphate diet when serum phosphate level is >5.5 mg/dL. For serum phosphate levels >7 mg/dL, initiate phosphate lowering therapy and withhold, reduce the dose, or permanently discontinue PEMAZYRE based on duration and severity of hyperphosphatemia as recommended in the prescribing information.

Embryo-Fetal Toxicity
Based on findings in an animal study and its mechanism of action, PEMAZYRE can cause fetal harm when administered to a pregnant woman. Oral administration of pemigatinib to pregnant rats during the period of organogenesis caused fetal malformations, fetal growth retardation, and embryo-fetal death at maternal exposures lower than the human exposure based on area under the curve (AUC) at the clinical dose of 13.5 mg.

Advise pregnant women of the potential risk to the fetus. Advise female patients of reproductive potential to use effective contraception during treatment with PEMAZYRE and for 1 week after the last dose. Advise males with female partners of reproductive potential to use effective contraception during treatment with PEMAZYRE and for 1 week after the last dose.

Adverse Reactions:  Cholangiocarcinoma
Serious adverse reactions occurred in 45% of patients receiving PEMAZYRE (n=146). Serious adverse reactions in ≥2% of patients who received PEMAZYRE included abdominal pain, pyrexia, cholangitis, pleural effusion, acute kidney injury, cholangitis infective, failure to thrive, hypercalcemia, hyponatremia, small intestinal obstruction, and urinary tract infection. Fatal adverse reactions occurred in 4.1% of patients, including failure to thrive, bile duct obstruction, cholangitis, sepsis, and pleural effusion.

Permanent discontinuation due to an adverse reaction occurred in 9% of patients who received PEMAZYRE. Adverse reactions requiring permanent discontinuation in ≥1% of patients included intestinal obstruction and acute kidney injury.

Dosage interruptions due to an adverse reaction occurred in 43% of patients who received PEMAZYRE.  Adverse reactions requiring dosage interruption in ≥1% of patients included stomatitis, palmar-plantar erythrodysesthesia syndrome, arthralgia, fatigue, abdominal pain, AST increased, asthenia, pyrexia, ALT increased, cholangitis, small intestinal obstruction, alkaline phosphatase increased, diarrhea, hyperbilirubinemia, electrocardiogram QT prolonged, decreased appetite, dehydration, hypercalcemia, hyperphosphatemia, hypophosphatemia, back pain, pain in extremity, syncope, acute kidney injury, onychomadesis, and hypotension.

Dose reductions due to an adverse reaction occurred in 14% of patients who received PEMAZYRE.  Adverse reactions requiring dosage reductions in ≥1% of patients who received PEMAZYRE included stomatitis, arthralgia, palmar-plantar erythrodysesthesia syndrome, asthenia, and onychomadesis.

Clinically relevant adverse reactions occurring in ≤10% of patients included fractures (2.1%). In all patients treated with pemigatinib, 0.5% experienced pathologic fractures (which included patients with and without cholangiocarcinoma [N = 635]). Soft tissue mineralization, including cutaneous calcification, calcinosis, and non-uremic calciphylaxis associated with hyperphosphatemia were observed with PEMAZYRE treatment.

Within the first 21-day cycle of PEMAZYRE dosing, serum creatinine increased (mean increase of 0.2 mg/dL) and reached steady state by Day 8, and then decreased during the 7 days off therapy. Consider alternative markers of renal function if persistent elevations in serum creatinine are observed.

In cholangiocarcinoma (n=146) the most common adverse reactions (incidence ≥20%) were hyperphosphatemia (60%), alopecia (49%), diarrhea (47%), nail toxicity (43%), fatigue (42%), dysgeusia (40%), nausea (40%), constipation (35%), stomatitis (35%), dry eye (35%), dry mouth (34%), decreased appetite (33%), vomiting (27%), arthralgia (25%), abdominal pain (23%), hypophosphatemia (23%), back pain (20%), and dry skin (20%).

Drug Interactions
Avoid concomitant use of strong and moderate CYP3A inhibitors with PEMAZYRE. Reduce the dose of PEMAZYRE if concomitant use with a strong or moderate CYP3A inhibitor cannot be avoided. Avoid concomitant use of strong and moderate CYP3A inducers with PEMAZYRE.  
Special Populations
Advise lactating women not to breastfeed during treatment with PEMAZYRE and for 1 week after the last dose.

Multiple sclerosis (MS) is one of the most common causes of neurological disability in young adults, occurring more frequently in women than men. The development of anti-cluster of differentiation 20 (CD20) monoclonal antibodies (mAbs) in recent years has significantly changed the way we treat MS. Compared to older standards of care, such as chemotherapy and immunosuppressive drugs, anti-CD20 mAbs have been shown to be more effective in treating MS with fewer side effects. 

Data have shown that B cells play a crucial role in the pathogenesis of MS via antigen-driven autoantibody responses and the cross-regulation of T-helper cells. CD20 is a protein that is expressed on the surface of B cells. Since B cells express the surface molecule CD20 at all points of differentiation, they provide a specific target for mAbs and are used to treat certain types of cancer and autoimmune disorders, including MS.

In people living with MS, the immune system mistakenly attacks the myelin sheath, a protective layer that surrounds nerve fibers in the central nervous system. This attack can cause inflammation and damage to the myelin sheath, leading to the development of various symptoms such as muscle weakness, vision problems, and issues with coordination and balance.

Anti-CD20 antibodies work by targeting and destroying B cells, which play a role in the immune system's attack on the myelin sheath. By targeting and destroying these cells, anti-CD20 antibodies may help to reduce the inflammation and damage to the myelin sheath and improve symptoms of MS.

There are several anti-CD20 mAbs used for the treatment of MS, including ocrelizumab, ofatumumab, ublituximab, and rituximab. Each drug has a unique mechanism of action and safety profile and distinct monitoring requirements. These therapies have been shown to deplete circulating B cells significantly for a certain amount of time, and they may be used in combination with other medications to treat MS. 

Ocrelizumab, a humanized anti-CD20 mAb administered by intravenous (IV) infusion, was approved in March 2017 by the US Food and Drug Administration (FDA) and is the first proven treatment to reduce disability progression in both primary progressive MS and relapsing MS. Interestingly, ocrelizumab binds to a CD20 epitope that overlaps partially with the epitope to which rituximab binds.

Ofatumumab is the first fully human anti-CD20 mAb and was approved by the FDA in August 2020 for treating relapsing forms of MS. The approval was on the basis of data from the phase 3 ASCLEPIOS I and II trials, which compared ofatumumab with teriflunomide, an oral agent that reduces the activity of proliferating T lymphocytes and B lymphocytes, mitigating the overall inflammatory response in MS. Subcutaneous ofatumumab demonstrated better efficacy than oral teriflunomide in reducing the annualized relapse rate in patients with MS. 

Ublituximab was recently approved by the FDA for treatment of relapsing forms of MS, including relapsing-remitting MS and active secondary progressive MS. Ublituximab works much like other anti-CD20 antibodies; however, it has been glycoengineered so that certain altered sugar molecules attached to the antibody increase its effectiveness. 

Rituximab is a chimeric monoclonal B-cell–depleting anti-CD20 antibody that has also showed promise as an escalation and as a first-line therapy for MS. The FDA has not approved it for this specific use yet, so its use is considered “off label.” A 2017 study showed that ofatumumab was more effective at depleting B cells than high doses of IV rituximab. 

It is important to note that anti-CD20 antibodies are not a cure for MS, and although they show promise for some patients, these agents do not work for everyone. The progress, severity, and specific symptoms of MS in any individual cannot yet be predicted; however, advances in research and treatment are leading to better understanding and moving us closer to curing this unpredictable, debilitating disease.

Multiple sclerosis (MS) is one of the most common causes of neurological disability in young adults, occurring more frequently in women than men. The development of anti-cluster of differentiation 20 (CD20) monoclonal antibodies (mAbs) in recent years has significantly changed the way we treat MS. Compared to older standards of care, such as chemotherapy and immunosuppressive drugs, anti-CD20 mAbs have been shown to be more effective in treating MS with fewer side effects. 

Data have shown that B cells play a crucial role in the pathogenesis of MS via antigen-driven autoantibody responses and the cross-regulation of T-helper cells. CD20 is a protein that is expressed on the surface of B cells. Since B cells express the surface molecule CD20 at all points of differentiation, they provide a specific target for mAbs and are used to treat certain types of cancer and autoimmune disorders, including MS.

Migraine is a condition that particularly affects the population of reproductive-aged women. A significant amount of the literature discusses the effect of estrogen as a migraine trigger and specifically migraine with aura as a vascular risk factor. One topic that is not discussed in the literature is whether migraine could be a risk for miscarriage, also known as spontaneous abortion. The National Institutes of Health (NIH)-funded study by Crowe and colleagues looks at this risk, especially as it relates to the frequency of migraine, the use of acute migraine medications, and caffeine intake.

This was a broad study, including nearly 2000 patients with migraine, and was a continuation of a prior ongoing NIH-funded epidemiologic study. The initial study enrolled nearly 8000 participants, all of whom were women aged 21-45 years, were in a pregnancy planning stage, and were followed for up to 12 months or until a reported pregnancy. Questionnaires were given preconception, as well as early in pregnancy (defined as 8-9 weeks' gestation), and late in pregnancy (defined as 32 weeks' gestation).

During this study 19% of pregnancies ended in spontaneous abortion. A history of migraine preconception was not associated with spontaneous abortion risk on the basis of hazard ratios. There was a slight risk in those taking some migraine medication daily, either prophylactic or analgesic. Frequency of migraine itself was not noted as a risk for spontaneous abortion.

It is necessary that this important study be followed by further investigations looking at specific medication classes and their potential risk for spontaneous abortion. Migraine itself does not appear to be a risk for miscarriage; however, there remains the possibility that some preventive or acute medications may elevate this risk. At the current moment, there is not enough information to draw a conclusion. All clinicians who treat people with migraine, particularly women who are in their reproductive years, should continue to have conversations regarding pregnancy planning and the adjustment of both preventive and acute medications prior to conception.

Neck pain is a common comorbidity of both chronic and acute migraine, and botulinum toxin is a US Food and Drug Administration–approved treatment both for chronic migraine and certain painful neck conditions, including cervical dystonia. Migraine itself can be a disabling condition; when migraine is combined with other painful comorbidities the likelihood of disability becomes increased significantly. The standard PREEMPT protocol for botulinum toxin injection in chronic migraine of 155 units includes a number of injections in the trapezius and cervical paraspinal muscles. Many clinicians will give additional injections into these muscles and other areas around the neck, specifically targeting areas of neck and shoulder spasm and tenderness. Onan and colleagues investigated the quality of life and disability scores of patients who received these additional injections.

This was an open study, in which participants were given an additional 30 units of botulinum toxin into the general neck areas in a follow-the-pain protocol. The authors, used as a primary outcome, the reduction in the Migraine Disability Assessment (MIDAS) and Neck Disability Index (NDI) scores at 4 weeks and 3 months. The secondary outcome was the Headache Impact Test (HIT-6) score. An objective assessment of neck mobility or a quantification of trigger points were not calculated.

All scores, both the primary and secondary outcomes, were significantly decreased, and quality of life was also noted to be significantly improved with these additional injections. Most clinicians receive a 200-unit vial of botulinum toxin for each of their chronic migraine protocol injections. There is a growing body of evidence to argue that the additional units of botulinum toxin significantly improve outcomes, both regarding headache and neck pain. This study argues for delivering these additional injections of botulinum toxin, especially when neck pain is more prominent.

Much has been written about diet triggers and migraine recently. There has been some evidence for specific diet changes, ie, the addition of foods or nutrients that can be helpful or preventive for migraine. There is some evidence for the addition of omega-3 fatty acids. Huang and He investigated the effect of a high fiber diet on migraine frequency and severity.

This was a cross-sectional study involving data collected from the NIH/Centers for Disease Control and Prevention–sponsored National Health and Nutrition Examination Survey trial from 1999 to 2004. In the studied population, severe headache and migraine was present in approximately 20%, and dietary fiber intake was delineated on the basis of whether it was more than or less than 100 g/d. This study assessed dietary intake of fiber, via a 24-hour dietary recall that was conducted by trained interviewers during two interviews conducted over the course of 2 years.

A total of 12,000 participants were included in the study. There was a significant decrease in migraine severity between those with a higher and lower dietary fiber intake. The incidence of severe headache or migraine, as defined by frequency and severity, decreased in participants who had a dietary fiber intake > 100 g/d. The authors found that for every 10 g/d increase in dietary fiber intake, the prevalence of severe headache or migraine decreased by approximately 11%.

Although much has been written about the association between diet and migraine, most of the literature focuses on the avoidance of specific dietary triggers. A different consideration now exists, one that will likely increase compliance with dietary recommendations. Specifically, people treating patients with migraine can make recommendations regarding dietary changes that focus on adding specific healthy foods or other changes that can actually be associated with improving migraine frequency long-term. Recommending healthy fats, such as omega-3 fatty acids, and high fiber should be done for nearly all patients with migraine.

HMG-CoA reductase inhibitors (statins) have been shown to effectively reduce low-density lipoprotein cholesterol (LDL-C) as well as morbidity and mortality in patients who have either atherosclerotic cardiovascular disease (ASCVD) or risk factors for ASCVD.^1-12 However, research shows that up to 20% of patients are unable to tolerate statin therapy due to muscle-related adverse events (AEs).¹³ This presents a substantial clinical challenge, as current management strategies for patients with statin-associated muscle symptoms, such as intermittent administration of statins and ezetimibe, seldom achieve the > 50% LDL-C reduction recommended by the 2018 American Heart Association/American College of Cardiology Clinical Practice Guidelines.¹⁴ Additionally, statin-intolerant patients who have antihyperlipidemic medication lowered or discontinued are at an increased risk of future cardiovascular events.¹⁵ Observational data also show that about 70% of adult patients (primarily with genetic lipid disorders such as heterozygous familial hypercholesterolemia) do not achieve an LDL-C level < 100 mg/dL despite treatment with maximum doses of statins with or without ezetimibe.^16,17

PCSK9 inhibitors (PCSK9i) have robust efficacy data to support use in patients who do not meet their LDL-C goal despite maximally tolerated lipid therapy.¹⁴ However, long-term safety data for PCSK9i are not as robust as its efficacy data. Specifically, safety data relating to muscle-related AEs, which are the most widely recognized AE associated with statins, have only been reported in a few clinical trials with varying incidence rates, levels of significance, and relatively small study populations. Furthermore, the real-world prevalence of muscle-related PCSK9i AEs is unknown. Clinical guidance for management strategies for muscle-related AEs associated with PCSK9i is largely lacking. For this study, muscle-related AEs were defined as any new or unusual muscle soreness, weakness, cramping, aches, and stiffness that persists, is generally bilateral, and typically affects the large muscles. It is important to note, that muscle-related AEs associated with statins, ezetimibe, and PCSK9i can be attributed to the nocebo effect.

According to the prescribing information for alirocumab and evolocumab, myalgia, muscle spasms, and musculoskeletal pain each occurred in < 5% of the study populations.^18,19 From these data, muscle-related PCSK9i AEs are thought to be relatively rare, based on the ODYSSEY-OUTCOME and FOURIER trials, which did not enroll statin-intolerant patients.^20,21 However, currently available safety data from 3 small, randomized clinical trials specifically in statin-intolerant patients taking a PCSK9i suggest that muscle-related AEs occur at a rate of 12.2% to 32.5% and discontinuation rates varied from 0% to 15.9%.^22-25 As the incidence rates of muscle-related AEs in the prescribing information and clinical trials varied widely, this study will provide quantitative data on the percentage of patients that developed muscle-related PCSK9i AEs in a veteran population to help shed light on a topic that is not well studied.

Methods

This was a single-center, retrospective chart review of patients prescribed a PCSK9i between December 1, 2017, and September 1, 2021, and were managed in a pharmacy-led patient aligned care team (PACT) clinic at the Wilkes-Barre US Department of Veterans Affairs (VA) Medical Center (WBVAMC) in Pennsylvania. This study was approved by the Coatesville VA Medical Center Institutional Review Board, which oversees research conducted at WBVAMC. Veterans aged ≥ 18 years were included in the study. Patients were excluded if they had a history of serious hypersensitivity reaction to a PCSK9i or rhabdomyolysis or did not meet the VA criteria for use.²⁶

The primary outcome was the percentage of patients who developed a muscle-related AE while on a PCSK9i in a PACT clinic. Data were further analyzed based on patients who (1) tolerated a full PCSK9i dose; (2) tolerated alternative PCSK9i following initial intolerance; (3) required a PCSK9i dose reduction, or (4) discontinued PCSK9i. A secondary outcome was the percentage of statin- and/or ezetimibe-intolerant patients in these 4 groups. Another secondary outcome was the management strategies taken for patients who were on a reduced (monthly) dose of PCSK9i who did not reach their LDL-C goal. Management strategies that were assessed included restarting weekly statin, restarting weekly ezetimibe, increasing the dose of the same PCSK9i administered monthly, and switching to an alternative PCSK9i.

Data were collected using the VA Computerized Patient Record System (CPRS) and stored in a secure, locked spreadsheet. Baseline patient demographic characteristics collected included age (at PCSK9i start); sex; race; and PCSK9i name, dose, and frequency. We recorded when a patient switched PCSK9i, whether or not it was due to a muscle-related AE, and the name of the original PCSK9i. Also collected were lipid therapy intolerances prior to PCSK9i initiation (ie, intolerance to statin, ezetimibe, or both).

Patients were considered statin intolerant due to a muscle-related AE in accordance with the VA PCSK9i Criteria for Use, which requires trial of at least 3 statins, one of which was trialed at the lowest dosage approved by the US Food and Drug Administration (FDA) and resulted in intolerable skeletal muscle AEs that worsened during treatment and resolved when the statin was stopped. For our study purposes, patients taking alternative day dosing of statins due to muscle-related AEs (ie, 2- or 3-times weekly dosing) were not considered statin intolerant; however, patients taking once-weekly statin dosing were considered statin intolerant. Patients were considered ezetimibe intolerant due to a muscle-related AE if the intolerance was due to skeletal muscle concerns that worsened during treatment and resolved when ezetimibe was stopped. Patients were considered PCSK9i intolerant due to a muscle-related AE if the intolerance was due to skeletal muscle concerns that worsened during treatment and resolved when the PCSK9i was stopped. Patients with non–muscle-related intolerances to statins, ezetimibe, and PCSK9i were not considered statin, ezetimibe, and PCSK9i intolerant.

Alirocumab was initiated at 75 mg subcutaneous (SQ) once every 2 weeks or evolocumab 140 mg SQ once every 2 weeks in our study. The protocol allowed for a dose reduction of alirocumab 75 mg SQ once monthly if a patient experienced AEs, but this dose reduction strategy was not used for any patients on evolocumab in this study. Of note, alirocumab 75 mg SQ once monthly is not an FDA-approved dosing strategy. However, it is similar in concept to the alternative statin dosing (ie, alternate day dosing, once-weekly dosing) and may avoid the need to discontinue PCSK9i therapy altogether.

A review of the CPRS also documented whether a muscle-related AE occurred while the patient was on a PCSK9i (if yes, the specific AE was recorded), the result of PCSK9i therapy (tolerated full dose, required a dose reduction, switched medication, or discontinued), and management strategies taken for patients who did not meet their LDL-C goal while on a reduced (monthly) PCSK9i dose. Prior lipid therapy intolerances, PCSK9i-related AEs, results of PCSK9i therapy, and management strategies for patients who did not meet LDL-C goal while on a reduced PCSK9i dose were obtained by reviewing the PACT pharmacist’s clinic notes and assessment, along with clinic notes and medication history listed within the CPRS.

Statistical Analysis

Descriptive statistics were used for the demographic characteristics of study patients. The primary outcome was calculated as a binary measure (yes/no) of whether the patient developed a muscle-related AE while on a PCSK9i. The secondary outcome of statin, ezetimibe, or statin and ezetimibe intolerances in subgroups also was calculated as a binary measure.

Results

For the study, 156 charts were reviewed and 137 patients were included (Figure).

For the secondary results, 4 patients (2.9%) tolerated an alternate PCSK9i (evolocumab 140 mg SQ every 2 weeks) after initial intolerance to PCSK9i, 16 (11.7%) required a dose reduction, and 6 (4.4%) discontinued PCSK9i due to a muscle-related AE.

Discussion

This retrospective study found 17.5% of patients experienced muscle-related PCSK9i AEs. These occurred at a higher rate than reported in the prescribing information (< 5%) and were similar to the incidence rates reported in the GAUSS-2, GAUSS-3, and ODYSSEY-ALTERNATIVE clinical trials (12.0%-32.5%), which is what we hypothesized.^18,19,22-25 It is important to note that the incidence rates of muscle-related AEs reported in the prescribing information for alirocumab and evolocumab were based on trials that did not include statin- and/or ezetimibe-intolerant patients; whereas many patients in our study and patients in the clinical trials were statin and/or ezetimibe intolerant.

Additionally, a new study by Donald and colleagues found an incidence rate of 32% to 36% for muscle-related PCSK9i AEs.²⁷ Collectively, the data from clinical trials and our study indicate that patients with prior intolerances to statin and/or ezetimibe appear to have a higher likelihood of developing a muscle-related PCSK9i intolerance. In our study, 23 of 24 patients who developed a muscle-related PCSK9i AE had a prior history of statin and/or ezetimibe intolerances. This should alert clinicians prescribing PCSK9i in patients with a history of statin and/or ezetimibe intolerance to counsel their patients on the possibility of muscle-related PCSK9i AEs and management strategies. However, it is important to note that there was a substantial number of patients in our study who were statin and/or ezetimibe intolerant due to a prior muscle-related AE who tolerated the full dose of PCSK9i.

To our knowledge, this was the first trial to evaluate muscle-related PCSK9i AEs in a veteran population. Additionally, our study appears to be the first to use 2 PCSK9i dosing strategies that are not FDA approved: Dose reduction for patients who experienced a muscle-related AE on alirocumab 75 mg SQ every 2 weeks and dose escalation for patients who did not meet their LDL-C goal on alirocumab 75 mg SQ monthly following an initial intolerance to 2-week dosing. The dose-reduction strategy allowed patients who experienced a muscle-related AE to alirocumab 75 mg to reduce administration from every 2 weeks to monthly.

This strategy was only performed with alirocumab, the preferred PCSK9i at WBVAMC, but the same dose-reduction strategy can theoretically be used with evolocumab as well. Reduced monthly dosing of alirocumab allowed patients with a prior intolerance to remain on a lower dosage without discontinuation. This is important because as noted by Myers and colleagues, individuals without access to PCSK9i were found to have a significantly higher incidence ratio of cardiovascular events compared with those taking PCSK9i.¹⁵ Also of note, > 30% of patients on the reduced monthly dose of alirocumab still met their LDL-C goal. Therefore, using this dose-reduction strategy (instead of patients discontinuing therapy altogether due to a muscle-related intolerance) can lessen the risk of major adverse cardiovascular events (MACE) as well as mitigate muscle-related AEs that occurred while on 2-week PCSK9i dosing regimens. While we acknowledge that this reduced monthly dose of either alirocumab or evolocumab is not FDA approved, it is similar to alternative statin dosing that also is not FDA approved but may minimize the need to discontinue PCSK9i therapy. It would be beneficial if these dosing strategies were investigated by future research.

The dose-escalation strategy for patients who did not meet their LDL-C goal while on the reduced, monthly dose of alirocumab also was unique. Alirocumab was increased from 75 mg SQ once monthly to 150 mg SQ once monthly. Interestingly, we found that through the end of the chart review period, all patients tolerated the increase well, despite having an initial muscle-related AE to alirocumab 75 mg every 2 weeks, which is the same total monthly dosage. This approach is similar to that of once-weekly statin dosing or a drug holiday and may be explained by the long half-life of PCSK9i. Regardless of the mechanism, this finding suggests that an increased monthly dose of PCSK9i is a potential alternative for patients who cannot tolerate the FDA-approved dose. However, the ability for patients to achieve goal LDL-C on the monthly dosage requires future study.

Limitations

The results of this study should be considered with the following limitations. First, this was a retrospective chart review performed over a prespecified period. Any muscle-related AEs or LDL-C lowering effects from PCSK9i that occurred outside the review period were not captured. Our study was small and only included 137 patients, though it was similar in size to the GAUSS-2, GAUSS-3, and ODYSSEY-ALTERNATIVE trials.^22-24 Additionally, the study was primarily composed of White men and may not be representative of other populations. Some muscle-related PCSK9i AEs may be attributed to the nocebo. Last, our study did not capture patients on a PCSK9i who were not followed in the PACT clinic.

Conclusions

We found that muscle-related PCSK9i AEs occurred at a similar rate as those reported in previous clinical trials and exceeded the incidence rate reported in the prescribing information for alirocumab and evolocumab. It appears that patients who have a prior muscle-related intolerance to a statin and/or ezetimibe had a higher likelihood of developing a muscle-related PCSK9i AE. In our study, only 1 patient developed a muscle-related PCSK9i AE who did not have a prior history of muscle-related intolerance to either a statin or ezetimibe. However, in our study, a substantial percentage of patients with statin and/or ezetimibe intolerances tolerated the full PCSK9i dose well, proving that PCSK9i are still a reasonable alternative for patients with prior intolerances to statins and/or ezetimibe.

HMG-CoA reductase inhibitors (statins) have been shown to effectively reduce low-density lipoprotein cholesterol (LDL-C) as well as morbidity and mortality in patients who have either atherosclerotic cardiovascular disease (ASCVD) or risk factors for ASCVD.^1-12 However, research shows that up to 20% of patients are unable to tolerate statin therapy due to muscle-related adverse events (AEs).¹³ This presents a substantial clinical challenge, as current management strategies for patients with statin-associated muscle symptoms, such as intermittent administration of statins and ezetimibe, seldom achieve the > 50% LDL-C reduction recommended by the 2018 American Heart Association/American College of Cardiology Clinical Practice Guidelines.¹⁴ Additionally, statin-intolerant patients who have antihyperlipidemic medication lowered or discontinued are at an increased risk of future cardiovascular events.¹⁵ Observational data also show that about 70% of adult patients (primarily with genetic lipid disorders such as heterozygous familial hypercholesterolemia) do not achieve an LDL-C level < 100 mg/dL despite treatment with maximum doses of statins with or without ezetimibe.^16,17

PCSK9 inhibitors (PCSK9i) have robust efficacy data to support use in patients who do not meet their LDL-C goal despite maximally tolerated lipid therapy.¹⁴ However, long-term safety data for PCSK9i are not as robust as its efficacy data. Specifically, safety data relating to muscle-related AEs, which are the most widely recognized AE associated with statins, have only been reported in a few clinical trials with varying incidence rates, levels of significance, and relatively small study populations. Furthermore, the real-world prevalence of muscle-related PCSK9i AEs is unknown. Clinical guidance for management strategies for muscle-related AEs associated with PCSK9i is largely lacking. For this study, muscle-related AEs were defined as any new or unusual muscle soreness, weakness, cramping, aches, and stiffness that persists, is generally bilateral, and typically affects the large muscles. It is important to note, that muscle-related AEs associated with statins, ezetimibe, and PCSK9i can be attributed to the nocebo effect.

According to the prescribing information for alirocumab and evolocumab, myalgia, muscle spasms, and musculoskeletal pain each occurred in < 5% of the study populations.^18,19 From these data, muscle-related PCSK9i AEs are thought to be relatively rare, based on the ODYSSEY-OUTCOME and FOURIER trials, which did not enroll statin-intolerant patients.^20,21 However, currently available safety data from 3 small, randomized clinical trials specifically in statin-intolerant patients taking a PCSK9i suggest that muscle-related AEs occur at a rate of 12.2% to 32.5% and discontinuation rates varied from 0% to 15.9%.^22-25 As the incidence rates of muscle-related AEs in the prescribing information and clinical trials varied widely, this study will provide quantitative data on the percentage of patients that developed muscle-related PCSK9i AEs in a veteran population to help shed light on a topic that is not well studied.

Methods

This was a single-center, retrospective chart review of patients prescribed a PCSK9i between December 1, 2017, and September 1, 2021, and were managed in a pharmacy-led patient aligned care team (PACT) clinic at the Wilkes-Barre US Department of Veterans Affairs (VA) Medical Center (WBVAMC) in Pennsylvania. This study was approved by the Coatesville VA Medical Center Institutional Review Board, which oversees research conducted at WBVAMC. Veterans aged ≥ 18 years were included in the study. Patients were excluded if they had a history of serious hypersensitivity reaction to a PCSK9i or rhabdomyolysis or did not meet the VA criteria for use.²⁶

The primary outcome was the percentage of patients who developed a muscle-related AE while on a PCSK9i in a PACT clinic. Data were further analyzed based on patients who (1) tolerated a full PCSK9i dose; (2) tolerated alternative PCSK9i following initial intolerance; (3) required a PCSK9i dose reduction, or (4) discontinued PCSK9i. A secondary outcome was the percentage of statin- and/or ezetimibe-intolerant patients in these 4 groups. Another secondary outcome was the management strategies taken for patients who were on a reduced (monthly) dose of PCSK9i who did not reach their LDL-C goal. Management strategies that were assessed included restarting weekly statin, restarting weekly ezetimibe, increasing the dose of the same PCSK9i administered monthly, and switching to an alternative PCSK9i.

Data were collected using the VA Computerized Patient Record System (CPRS) and stored in a secure, locked spreadsheet. Baseline patient demographic characteristics collected included age (at PCSK9i start); sex; race; and PCSK9i name, dose, and frequency. We recorded when a patient switched PCSK9i, whether or not it was due to a muscle-related AE, and the name of the original PCSK9i. Also collected were lipid therapy intolerances prior to PCSK9i initiation (ie, intolerance to statin, ezetimibe, or both).

Patients were considered statin intolerant due to a muscle-related AE in accordance with the VA PCSK9i Criteria for Use, which requires trial of at least 3 statins, one of which was trialed at the lowest dosage approved by the US Food and Drug Administration (FDA) and resulted in intolerable skeletal muscle AEs that worsened during treatment and resolved when the statin was stopped. For our study purposes, patients taking alternative day dosing of statins due to muscle-related AEs (ie, 2- or 3-times weekly dosing) were not considered statin intolerant; however, patients taking once-weekly statin dosing were considered statin intolerant. Patients were considered ezetimibe intolerant due to a muscle-related AE if the intolerance was due to skeletal muscle concerns that worsened during treatment and resolved when ezetimibe was stopped. Patients were considered PCSK9i intolerant due to a muscle-related AE if the intolerance was due to skeletal muscle concerns that worsened during treatment and resolved when the PCSK9i was stopped. Patients with non–muscle-related intolerances to statins, ezetimibe, and PCSK9i were not considered statin, ezetimibe, and PCSK9i intolerant.

Alirocumab was initiated at 75 mg subcutaneous (SQ) once every 2 weeks or evolocumab 140 mg SQ once every 2 weeks in our study. The protocol allowed for a dose reduction of alirocumab 75 mg SQ once monthly if a patient experienced AEs, but this dose reduction strategy was not used for any patients on evolocumab in this study. Of note, alirocumab 75 mg SQ once monthly is not an FDA-approved dosing strategy. However, it is similar in concept to the alternative statin dosing (ie, alternate day dosing, once-weekly dosing) and may avoid the need to discontinue PCSK9i therapy altogether.

A review of the CPRS also documented whether a muscle-related AE occurred while the patient was on a PCSK9i (if yes, the specific AE was recorded), the result of PCSK9i therapy (tolerated full dose, required a dose reduction, switched medication, or discontinued), and management strategies taken for patients who did not meet their LDL-C goal while on a reduced (monthly) PCSK9i dose. Prior lipid therapy intolerances, PCSK9i-related AEs, results of PCSK9i therapy, and management strategies for patients who did not meet LDL-C goal while on a reduced PCSK9i dose were obtained by reviewing the PACT pharmacist’s clinic notes and assessment, along with clinic notes and medication history listed within the CPRS.

Statistical Analysis

Descriptive statistics were used for the demographic characteristics of study patients. The primary outcome was calculated as a binary measure (yes/no) of whether the patient developed a muscle-related AE while on a PCSK9i. The secondary outcome of statin, ezetimibe, or statin and ezetimibe intolerances in subgroups also was calculated as a binary measure.

Results

For the study, 156 charts were reviewed and 137 patients were included (Figure).

For the secondary results, 4 patients (2.9%) tolerated an alternate PCSK9i (evolocumab 140 mg SQ every 2 weeks) after initial intolerance to PCSK9i, 16 (11.7%) required a dose reduction, and 6 (4.4%) discontinued PCSK9i due to a muscle-related AE.

Conclusions

We found that muscle-related PCSK9i AEs occurred at a similar rate as those reported in previous clinical trials and exceeded the incidence rate reported in the prescribing information for alirocumab and evolocumab. It appears that patients who have a prior muscle-related intolerance to a statin and/or ezetimibe had a higher likelihood of developing a muscle-related PCSK9i AE. In our study, only 1 patient developed a muscle-related PCSK9i AE who did not have a prior history of muscle-related intolerance to either a statin or ezetimibe. However, in our study, a substantial percentage of patients with statin and/or ezetimibe intolerances tolerated the full PCSK9i dose well, proving that PCSK9i are still a reasonable alternative for patients with prior intolerances to statins and/or ezetimibe.

Growing up I can remember my father telling stories of service members in the medical battalion he commanded in World War II (WWII) who after the war with his encouragement and their GI Bill educational benefits went to school to become doctors, nurses, and dentists. They were among the 2,300,000 veterans who attended US colleges and universities through the Servicemen’s Readjustment Act passed in 1944. The American Legion navigated the bill through the twists and turns of congressional support, and it was one of their leaders who invented the catchy GI Bill shorthand.²

As with most political legislation, there were mixed motives driving passage of the act, and like many policies in America, the primary impetus was economic. While the war was raging overseas, at home the US Department of Labor predicted that by the war’s end, 16 million service members would be jobless. Apprehensive about the prospect of yet another financial depression, in 1943 a White House agency recommended that the federal government fund education and training for the individuals who had served during the war.²

While troops stormed the beaches of Normandy, wartime President Franklin D. Roosevelt (FDR) signed the bill that delivered not only educational and training opportunities for service members and veterans, but also funded home loans and US Department of Veterans Affairs (VA) hospitals. The bill was practical in that it provided not only tuition, but also books, supplies, a living stipend, and counseling for the students. The bill technically expired in 1956, but a series of extensions and expansions has been true to the original intention to offer those who served their nation in the military a better life as citizens.

Articles describing the impact of the GI Bill use terms like life changing and transformative.^3,4 Our contemporary culture makes it difficult to imagine how out of reach a college education was for the generation that fought WWII. Universities were primarily for the rich and connected, the powerful and privileged. Were it not for the upward social mobility the GI Bill propelled, the American dream would not have become a reality for many farmers, small town merchants, and factory workers. The GI Bill though could not by itself ensure equity. The systemic racism endemic in the United States and among the elected representatives who debated the bill resulted in many Black service members especially in the South being denied entrance to institutions of higher learning.⁵ Despite this invidious discrimination, the bill was a profound effort to help many other service members to successfully reintegrate into the society they had preserved and defended.⁴

“With the signing of this bill, a well-rounded program of special veterans’ benefits is nearly completed,” FDR said, capturing its noble intent: “It gives emphatic notice to the men and women in our armed forces that the American people do not intend to let them down.”⁶

Regrettably, we have not kept FDR’s pledge. Now unscrupulous businesses are preying on the aspirations of military personnel and veterans for an education and thwarting their ability to seek gainful employment. For more than a decade, respected news media have reported that for-profit universities were exploiting service members trying to improve their lives through obtaining a college education via the GI Bill.⁷ The sad irony is that what enabled the exploitation to occur was a major expansion of the benefits under the Post-9/11 GI Bill. This version granted educational funding to any individual who had served on active duty for 90 days or more after September 10, 2001.⁸ Federal law prohibits for-profit educational institutions from receiving more than 90% of their total revenue from federal student aid. A loophole in the law enabled these institutions to categorize GI Bill funding as private not government dollars. Bad old American greed drove these for-profit colleges and universities to aggressively recruit veterans who trusted in the good faith of the academic institutions. Once the GI Bill monies were exhausted, veterans had already invested so much time and energy in a degree or certificate, the schools could persuade them to take out student loans with the promise of job placement assistance that never materialized. They took advantage of the veterans’ hopes to fatten their own bottom line in the face of declining enrolments.⁹ Journalists, government, think tank reports, and even a documentary described the tragic stories of service members left unemployed with immense debt and degrees that to many of them were now worthless.¹⁰

After years of reporters exposing the scam and politically thwarted efforts to stop it, Congress and President Biden closed what was known as the 90/10 loophole. This ended the weaponization of education it had promoted. In October 2022, the US Department of Education announced its final rule to prohibit the widespread educational fraud that had betrayed so many veterans and service members, which Secretary Dennis McDonough described as “abuse.”¹¹Some readers may wonder why I have devoted an editorial to a topic that seems somewhat distant from the health care that is the primary domain of Federal Practitioner. It happens that education is in closer proximity to health for our patients than many of us might have realized. A 2018 Military Medicine study found that veterans who took advantage of the educational opportunities of the GI Bill had better health and reduced smoking, among other benefits.¹² This connection between health and education should serve as a source of pride for all of us in federal practice as we are part of organizations that affirm the holistic concept of health that embraces not just medicine but education, housing, and other services essential for comprehensive well-being.
