Major Research Findings

Alirocumab is a proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor that has been developed as a treatment for high cholesterol. 6 states that inhibiting PCSK9 is a promising therapeutic option to lower low-density lipoprotein cholesterol (LDL-C) levels. This study reported that PCSK9 inhibitors showed promising results in phase 2 clinical trials in patients with FH (familial hypercholesterolemia) or those who were intolerant to statin with LDL-C levels that were not on target levels. 6 reported that a 60%-70% reduction in LDL-C was observed, especially when subcutaneous injections were performed regularly every two weeks. 8 is a study that evaluated the efficacy of alirocumab in 1191 patients with a wide spectrum of mutations in genes causative for familial hypercholesterolemia. 9 is a study that assessed the efficacy and safety of alirocumab and evolocumab in patients with heterozygous familial hypercholesterolemia (FH) within a therapeutic program in Poland. These studies confirmed the efficacy and safety of alirocumab and evolocumab. 2 provides an overview of PCSK9 monoclonal antibodies, stating that they have been extensively studied in patients with hypercholesterolemia either as monotherapy or as an add-on to other LLTs. This study demonstrated that PCSK9 monoclonal antibodies significantly reduced low-density lipoprotein cholesterol (LDL-C) plasma levels, resulting in better LDL-C goal attainment. 3 evaluated the safety of the proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor alirocumab according to diabetes mellitus status. Using pooled data from 14 ODYSSEY trials, the study showed that the safety of alirocumab was equivalent in individuals with and without diabetes. 4 presents a case of gingival ischemia and petechiae in a patient medicated with PCSK9 inhibitor for hypercholesterolemia. This patient experienced gingival discomfort during eating and toothbrushing, coupled with the presence of gingival ischemia and petechiae, 3 days after a subcutaneous abdominal injection of 75-mg alirocumab for hypercholesterolemia. The authors contemplate on their possible pathogenesis. 5 is a study that developed and tested the content validity of a Patient-Reported Treatment Acceptance Measure for use in patients receiving treatment via subcutaneous injection. New therapies in development for lowering low-density lipoprotein cholesterol, such as alirocumab, require administration by subcutaneous injections. There is a need to assess the acceptance of such treatments and their mode of administration. 7 is a psychometric evaluation of a treatment acceptance measure for use in patients receiving treatment via subcutaneous injection. Alirocumab, a proprotein convertase subtilisin/kexin type 9 inhibitor, significantly reduces low-density lipoprotein cholesterol but requires subcutaneous injections rather than oral pills. To measure patients' acceptance of this treatment modality, a new patient-reported outcome, the Injection-Treatment Acceptance Questionnaire (I-TAQ), was developed. 1 reports a case series of transient injection site reactions to alirocumab during immune system activation. Injection site reactions (ISRs) are known side effects of the proprotein convertase subtilisin kexin 9 (PCSK9) inhibitor alirocumab. Transient ISR to alirocumab after a long phase of good tolerability have not been reported previously.

Reasons for Side Effects

PCSK9 inhibitors, such as alirocumab, are administered via subcutaneous injection, which can cause side effects such as inflammation and pain at the injection site. 6 reports injection site reactions as a side effect of PCSK9 inhibitors. 1 reports a case series of transient injection site reactions to alirocumab during immune system activation. 4 presents a case of gingival ischemia and petechiae in a patient medicated with PCSK9 inhibitor for hypercholesterolemia. This patient experienced gingival discomfort during eating and toothbrushing, coupled with the presence of gingival ischemia and petechiae, 3 days after a subcutaneous abdominal injection of 75-mg alirocumab for hypercholesterolemia. However, the causal relationship between this side effect and alirocumab administration is not clear.

Common Side Effects

Injection Site Reactions

The most common side effect of PCSK9 inhibitors, such as alirocumab, is injection site reactions. 6 reports injection site reactions as a side effect of PCSK9 inhibitors. 2 states that mild injection site reactions are the most frequently reported side effects of PCSK9 monoclonal antibodies. 1 reports a case series of transient injection site reactions to alirocumab during immune system activation. Injection site reactions (ISRs) are known side effects of the proprotein convertase subtilisin kexin 9 (PCSK9) inhibitor alirocumab. Transient ISR to alirocumab after a long phase of good tolerability have not been reported previously.

Gingival Ischemia and Petechiae

4 presents a case of gingival ischemia and petechiae in a patient medicated with PCSK9 inhibitor for hypercholesterolemia. This patient experienced gingival discomfort during eating and toothbrushing, coupled with the presence of gingival ischemia and petechiae, 3 days after a subcutaneous abdominal injection of 75-mg alirocumab for hypercholesterolemia. However, the causal relationship between this side effect and alirocumab administration is not clear.

Measures for Side Effects

Injection Site Reactions

Cooling the injection site before injection or warming it after injection can be effective in reducing injection site reactions. 6 reports injection site reactions as a side effect of PCSK9 inhibitors.
