Certolizumab Pegol (Cimzia)

Number: 0761

Brand Selection for Medically Necessary Indications

As defined in Aetna commercial policies, health care services are not medically necessary when they are more costly than alternative services that are at least as likely to produce equivalent therapeutic or diagnostic results. Cimzia (certolizumab pegol) is more costly to Aetna than other targeted immune modulators for certain indications. There is a lack of reliable evidence that Cimzia (certolizumab pegol) is superior to other lower cost targeted immune modulators. Therefore, Aetna considers Cimzia (certolizumab pegol) to be medically necessary only for members who have a contraindication, intolerance, or ineffective response to the available equivalent alternative targeted immune modulators for the following medically necessary indications per criteria below. Requirements for a trial of lower cost targeted immune modulators are waived for persons requesting Cimzia who are pregnant or breastfeeding.

• Moderately to severely active rheumatoid arthritis (RA)

  For the treatment of moderately to severely active RA, member has a contraindication, intolerance or ineffective response to all of the following available equivalent alternative targeted immune modulators (one-month trial): Enbrel, Humira, Kevzara, Orencia subcutaneous formulation, Rinvoq, and Xeljanz/Xeljanz XR.

• Moderate to severe plaque psoriasis

  For the treatment of moderate to severe chronic plaque psoriasis, member has a contraindication, intolerance or ineffective response to all of the following available equivalent alternative targeted immune modulators (one-month trial): Humira, Ilumya, Otezla, Skyrizi, Stelara (SQ), Taltz, and Tremfya.

• Active psoriatic arthritis (PsA)

  For the treatment of PsA, member has a contraindication, intolerance or ineffective response to all of the following available equivalent alternative targeted immune modulators (one-month trial): Cosentyx, Enbrel, Humira, and Otezla.

Experimental and Investigational

1. Aetna considers certolizumab pegol experimental and experimental for use in combination with biological disease-modifying antirheumatic drugs (bioDMARDs) including anakinra (Kineret) and tumor necrosis factor (TNF)-alpha inhibitors such as adalimumab (Humira), etanercept (Enbrel), golimumab (Simponi) and infliximab (Remicade).

2. Aetna considers measurements of certolizumab level and certolizumab antibody level experimental and investigational for individuals who are on certolizumab therapy because the clinical value of this approach has not been established.

3. Aetna considers certolizumab pegol experimental and investigational for all other indications (not an all-inclusive list) because its effectiveness for indications other than the ones listed above has not been established:

   • Behcet's disease
   • Ocular inflammation/uveitis
   • Sarcoidosis.

Background

U.S. Food and Drug Administration (FDA)-Approved Indications

• Reducing signs and symptoms of Crohn’s disease and maintaining clinical response in adult patients with moderately to severely active disease who have had an inadequate response to conventional therapy
• Treatment of adults with moderately to severely active rheumatoid arthritis
• Treatment of adult patients with active psoriatic arthritis
• Treatment of adults with active ankylosing spondylitis
• Treatment of adults with active non-radiographic axial spondyloarthritis with objective signs of inflammation
• Treatment of adults with moderate-to-severe plaque psoriasis who are candidates for systemic therapy or phototherapy

Certolizumab pegol is available as Cimzia (UCB, Inc., Smyrna, GA) which is a pegylated form of anti‐tumor necrosis factor‐alpha (anti‐TNFα). Certolizumab pegol has a high-affinity for human TNF-alpha and selectively targets TNF-alpha in inflamed tissue. Pegylation allows for subcutaneous dosing every four weeks. Certain inflammatory processes involve the overproduction of TNFα by the immune system. TNFα is one of the agents implicated in the auto‐immune response leading to conditions such as Crohn’s disease, rheumatoid arthritis, and psoriasis. Cimzia is an antibody that binds to circulating TNFα, thus diminishing the effects of this molecule in the inflammatory process. In vitro studies show that certolizumab is more potent and binds with greater affinity to TNFα than adalimumab and infliximab. Cimzia does not contain the Fc region and therefore does not activate the complement pathway or cause cell‐mediated cytotoxicity.

Cimzia carries a Black Box Warning for serious infections and malignancy. These include:

• Increased risk of serious infections leading to hospitalization or death including tuberculosis (TB), bacterial sepsis, invasive fungal infections (such as histoplasmosis), and infections due to other opportunistic pathogens
• Cimzia should be discontinued if a patient develops a serious infection or sepsis
• Perform test for latent TB; if positive, start treatment for TB prior to starting Cimzia
• Monitor all patients for active TB during treatment, even if initial latent TB test is negative
• Lymphoma and other malignancies, some fatal, have been reported in children and adolescent patients treated with TNF blockers, of which Cimzia is a member
• Cimzia is not indicated for use in pediatric patients.

In addition to risk of serious infection and malignancies, other labeled warnings and precautions include the following:

• New onset or worsening congestive heart failure
• Hypersensitivity reactions
• Hepatitis B virus reactivation
• Exacerbation or new onset demyelinating disease 
• Hematological reactions (including leukopenia, pancytopenia and thrombocytopenia)
• Increased risk of serious infections when Cimzia is used concomitantly with anakinra, abatacept, rituximab and natalizumab; thus, concomitant use with these drugs are not recommended
• Lupus-like syndrome
• Avoid use with live vaccines.

Most common adverse reactions (≥7%) include upper respiratory tract infection, rash, and urinary tract infection.

Ankylosing Spondylitis and Axial Spondyloarthritis

Spondyloarthritis is a term used to include a group of arthritis-associated conditions. One of the associated conditions include axial spndyloarthritis (axSpA), which is a potentially disabling inflammatory arthritis that typically affects the spine; however, may also affect joints in the arms and legs. Symptoms typically begin before the age of 45. Those with axSpA can be further classified into 2 subtypes such as ankylosing spondylitis (AS) and nonradiographic axial spondyloarthritis (nr-axSpA). Individuals affected by AS exhibit radiographic abnormalities consistent with sacrolitis, whereas, findings are absent or minimal on plain radiography for those with nr-axSpA. Individuals with nr-axSpA may have evidence of active inflammation of the sacroiliac (SI) joints on MRI findings (e.g., bone marrow edema of the joints). The diagnosis of axSpA, including AS and nr-axSpA, should be considered in persons with continuous chronic back pain prior to age 45, Per UpToDate, "there is no single historical feature, physical finding, laboratory test, or imaging study with sufficient specificity by itself to establish the diagnosis without the presence of additional abnormalities. Thus, the presence of a combination of features together with the exclusion of other diagnoses that may explain such symptoms or findings is necessary to arrive at an accurate diagnosis" (Yu and van Tubergen, 2018a).

Machado et al (2013) noted that biological agents directed against TNF represent therapeutic options for patients with ankylosing spondylitis with high disease activity despite use of non-steroidal anti-inflammatory drugs.  To evaluate the safety and effectiveness of the anti-TNF agents adalimumab, certolizumab, etanercept, golimumab, and infliximab for the treatment of ankylosing spondylitis, these researchers performed a systematic review of randomized clinical trials on adult patients with ankylosing spondylitis using articles culled from the Embase, Medline, Cochrane Controlled Trials Register and LILACS databases (September 2012), manual literature search, and the gray literature.  Study selections and data collection were performed by 2 independent reviewers, with disagreements solved by a 3rd reviewer.  The following outcomes were evaluated: ASAS 20 response, disease activity, physical function, vertebral mobility, adverse events, and withdraws.  The meta-analysis was performed using the Review Manager 5.1 software by applying the random effects model.  A total of 18 studies were included in this review.  No study of certolizumab was included.  Patients treated with anti-TNF agents were more likely to display an ASAS 20 response after 12/14 weeks (RR 2.21; 95 % confidence interval [CI]: 1.91; to 2.56) and 24 weeks (RR 2.68; 95 % CI: 2.06 to 3.48) compared with controls, which was also true for several other efficacy outcomes.  Meta-analysis of safety outcomes and withdraws did not indicate statistically significant differences between treatment and control groups after 12 or 30 weeks.  The authors concluded that adalimumab, etanercept, golimumab, and infliximab can effectively reduce the signs and symptoms of the axial component of ankylosing spondylitis.  Moreover, they stated that safety outcomes deserve further study, especially with respect to long-term follow-ups.

The FDA has approved Cimzia for adults with ankylosing spondylitis (UCB, 2013)  The approval of Cimzia for adults with active ankylosing spondylitis was based on a phase 3, multicenter, randomized, double-blind, placebo-controlled study designed to evaluate the efficacy and safety of Cimzia in patients with active axial spondyloarthritis, in which the majority had ankylosing spondylitis 

In the efficacy and safety study of certolizumab, patients with active axial spondyloarthritis were randomized (1:1:1) to receive certolizumab 200 mg every two weeks, 400 mg every four weeks or placebo (UCB, 2013). There were a total of 325 patients in the study, of which 178 had ankylosing spondylitis. All patients received a loading dose with certolizumab or placebo at weeks 0, 2 and 4. The primary efficacy variable, the proportion of patients achieving an ASAS20 response rate at week 12, was met with clinical and statistical significance in both dosing arms versus placebo. 

A greater proportion of ankylosing spondylitis patients treated with certolizumab 200 mg every two weeks or 400 mg every four weeks achieved ASAS20 response at week 12, compared with ankylosing spondylitis patients treated with placebo (UCB, 2013). Responses were similar in patients receiving certolizumab 200 mg every two weeks and 400 mg every four weeks. 

In this study, adverse events occurred in 70.4% of patients in the certolizumab group (combined dose) compared to 62.6% of patients in the placebo group (UCB, 2013). Serious adverse events occurred in 4.7% of patients in both the certollizumab group (combined dose) and in the placebo group. According to the manufacturer, the safety profile for patients with ankylosing spondylitis treated with certolizumab was similar to the safety profile seen in patients with rheumatoid arthritis and in patients with previous experience with certolizumab.

On March 28, 2019, the FDA announced the approval of Cimzia (certolizumab pegol) injection for the treatment of adults with non-radiographic axial spondyloarthritis (nr-axSpA) who have objective signs of inflammation. Nr-axSpA is a type of inflammatory arthritis that causes inflammation in the spine and other symptoms in which there is no visible damage seen on x-rays, thus, referred to as non-radiographic. FDA approval was based on outcomes from a phase 3, multi-center, double-blind, placebo-controlled 52-week study (C-AXSPAND) that randomized 317 adult patients with objective signs of inflammation indicated by elevated CRP levels, and/or sacrolitis on MRI. Patients received either Cimzia (400 mg at weeks 0, 2, and 4 followed by 200 mg every 2 weeks) or placebo plus other medications, which included NSAIDs, corticosteroids, analgesics and slow-acting anti-rheumatic drugs.The primary endpoint of the study was met, with 47.2% of patients treated with Cimzia demonstrating major improvement response in Ankylosing Spondylitis Disease Activity Score (ASDAS-MI) at week 52, compared to 7.0% of patients treated with placebo. The secondary endpoint of the study was also met, with 47.8% of Cimzia-treated patients achieving a 40% improvement in Ankylosing Spondylitis Assessment Score (ASAS40) compared to 11.4% of placebo-treated patients at week 12. Furthermore, the safety profile was found to be similar to the safety profile seen in patients with RA and previous experience with Cimzia. The study investigators concluded that their results indicate that remission in nr-axSpA treated without biologics occurs infrequently, demonstrating the need for treatment beyond non-biologic therapy (Deodhar et al. 2019; FDA, 2019).

UpToDate recommends adding a tumor necrosis factor (TNF)-alpha inhibitor for patients with active axial SpA symptoms and have had an inadequate response to initial therapy with at least two NSAIDs consecutively rather than treatment with NSAIDs alone. TNF inhibitors (e.g., subcutaneous adalimumab) is an acceptable treatment option (Yu and van Tubergen, 2019b).

Behcet's Disease

Lopalco and colleagues (2017) described their experience with certolizumab pegol (CZP) in patients with Behcet's disease (BD) refractory to standardized therapies and previous biologic agents.  Retrieved data including demographic characteristics, clinical manifestations, and previous treatments were collected in 3 different specialized rheumatologic units in Italy.  In order to evaluate disease activity, the BD current activity form (BDCAF) has been used before starting CZP therapy and at each visit during treatment.  A total of 13 BD patients (mean age of 42.6 ± 8.8 years) with a disease duration of 8.80 ± 6.9 years, underwent CZP treatment for 6.92 ± 3.52 months; 6 patients (46.15 %) experienced a worsening of symptoms after 4.16 ± 1.21 months, whereas a satisfactory response was achieved in 7 patients (53.84 %) who were still on CZP therapy at the last follow-up visit (after 9.28 ± 3.03 months of treatment).  The mean decrease of BDCAF between the first and last visit was 0.308 ± 1.84 without reaching significant difference (mean of 8.3 ± 1.3 and 8 ± 2.08, respectively; p= 0.51).  During the whole study period, CZP was well-tolerated in all patients except for 1 who developed a generalized cutaneous reaction after the 3rd administration.  The authors concluded that these findings suggested that despite an improvement of clinical manifestations has been observed in more than 50 % of the patients, it is not possible to draw firm conclusions about the effectiveness of CZP in BD and further studies with larger cohorts of patients are needed.  Whether the increase of CZP dosage may ensure a better clinical response remains an unsolved issue that needs to be considered.

Crohn's Disease

Crohn's disease is a chronic, inflammatory bowel disease that affects more than 1 million people worldwide.  It has no cure and its cause is unknown.  Crohn's disease can cause diarrhea, fever, rectal bleeding, malnutrition, narrowing of the intestinal tract, obstructions, abscesses, cramping, and abdominal pain. It also can lead to fistulas (abnormal connections) leading from the intestine to the skin or internal organs.

In April 2008, the U.S. Food and Drug Administration (FDA) approved certolizumab pegol for adults with moderately-to-severely active Crohn's disease who have not responded to conventional therapies.  The approval of certolizumab pegol was based on safety and efficacy data from clinical trials in more than 1,500 patients with Crohn's disease.

The Pegylated Antibody Fragment Evaluation in Crohn's Disease: Safety and Efficacy (PRECiSE) program enrolled more than 1,300 patients in 4 trials and evaluated the safety and efficacy of certolizumab pegol.  The PRECiSE 1 and PRECiSE 2 studies were 26-week trials that evaluated induction and short-term maintenance of remission.  Outcome data from the PRECiSE 3 and PRECiSE 4 studies, designed to evaluate long-term maintenance of remission, have not yet been published.

The PRECiSE 1 trial, a placebo-controlled phase IIII study, stratified patients (n = 662) according to baseline levels of C-reactive protein (CRP).  Patients were randomly assigned to receive either 400 mg of certolizumab pegol or placebo subcutaneously at weeks 0, 2, and 4 and then every 4 weeks.  Primary endpoints were the induction of a response at week 6 and a response at both weeks 6 and 26.  Among patients with a baseline CRP level of at least 10 mg per liter, 37 % of patients in the certolizumab group had a response at week 6, as compared with 26 % in the placebo group.  At both weeks 6 and 26, the corresponding values were 22 % and 12 %, respectively.  In the overall population, response rates at week 6 were 35 % in the certolizumab group and 27 % in the placebo group; at both weeks 6 and 26, the response rates were 23 % and 16 %, respectively.  At weeks 6 and 26, the rates of remission in the 2 groups did not differ significantly.  Serious adverse events were reported in 10 % of patients in the certolizumab group and 7 % of those in the placebo group; serious infections were reported in 2 % and less than 1 %, respectively.  In the certolizumab group, antibodies to the drug developed in 8 % of patients, and anti-nuclear antibodies developed in 2 %.  The authors concluded that in patients with moderate-to-severe Crohn's disease, induction and maintenance therapy with certolizumab pegol was associated with a modest improvement in response rates, as compared with placebo, but with no significant improvement in remission rates (Sandborn et al, 2007).

The PRECiSE 2 trial, a placebo-controlled study, evaluated the efficacy of certolizumab pegol maintenance therapy in adults (n = 668) with moderate-to-severe Crohn's disease.  Certolizumab pegol (400 mg) was administered subcutaneously at weeks 0, 2, and 4 as induction therapy.  Patients with a clinical response (defined as reduction of at least 100 from the baseline score on the Crohn's Disease Activity Index [CDAI]) at week 6 were stratified according to their baseline CRP level and were randomly assigned to receive 400 mg of certolizumab pegol or placebo every 4 weeks through week 24, with follow-up through week 26.  Among patients with a response to induction therapy at week 6 (n = 428 or 64 %), the response was maintained through week 26 in 62 % of patients with a baseline CRP level of at least 10 mg per liter (the primary endpoint) who were receiving certolizumab pegol (versus 34 % of those receiving placebo) and in 63 % of patients in the intention-to-treat population who were receiving certolizumab pegol (versus 36 % receiving placebo).  Among patients with a response to induction therapy at week 6, remission (defined by a CDAI score of 150) at week 26 was achieved in 48 % of patients in the certolizumab group and 29 % of those in the placebo group.  The use of immunosuppressants, corticosteroids, and previous treatment with infliximab were not demonstrated to affect the response rate.  Serious infections, including one case of pulmonary tuberculosis, occurred in 3 % of patients receiving certolizumab pegol and in less than 1 % of patients receiving placebo.  Anti-nuclear antibodies developed in 8 % of the patients in the certolizumab group; antibodies against certolizumab pegol developed in 9 % of all patients who entered the induction phase.  The authors concluded that patients with moderate-to-severe Crohn's disease who had a response to induction therapy with 400 mg of certolizumab pegol were more likely to have a maintained response and a remission at 26 weeks with continued certolizumab pegol treatment than with a switch to placebo.

A Cochrane systematic review (2008) evaluated the evidence of the effectiveness of TNF-alpha blocking agents in the maintenance of remission in patients with Crohn's disease.  Randomized controlled trials involving patients greater than 18 years of age with Crohn's disease who had a clinical response or clinical remission with a TNF-alpha blocking agent, or patients with Crohn's disease in remission but unable to wean from corticosteroids, who were then randomized to maintenance of remission with a TNF-alpha blocking agent or placebo were selected for review.  Nine studies met all inclusion criteria.  Four different anti-TNF-alpha agents were evaluated (infliximab in 3 studies, CDP571 in 3 studies, adalimumab in 2 studies, and certolizumab in 1 study).  The authors reported that infliximab, adalimumab, and certolizumab maintained clinical remission, clinical response, had corticosteroid-sparing effects, and maintained fistula healing in patients with Crohn's disease.  There was no evidence to support the use of CDP571 for the maintenance of remission in Crohn's disease.  No comparative trials have evaluated the relative efficacy of these agents.  Adverse events were similar in the infliximab, adalimumab, and certolizumab groups compared with placebo, but study size and duration generally were insufficient to allow an adequate assessment of serious adverse events associated with long-term use.

In the Crohn's Disease Study Group, Rutgeerts et al (2008) reported the health-related quality of life (HRQoL) of patients with moderately-to-severely active Crohn's disease (n = 292) who received subcutaneous certolizumab pegol.  Patients with moderately-to-severely active Crohn's disease (n = 292) received subcutaneous certolizumab pegol 100, 200, or 400 mg or placebo at weeks 0, 4, and 8.  A post hoc analysis of the intent-to-treat population (290 patients with HRQoL data) assessed HRQoL by evaluating patients' responses to the self-administered inflammatory bowel disease questionnaire (IBDQ) at baseline and weeks 2, 4, 6, 8, 10, and 12.  Patients receiving certolizumab pegol 400 mg at weeks 0, 4, and 8 demonstrated, via their IBDQ total score, significantly greater improvement in HRQoL from baseline to week 12 and at all other time points compared with placebo.  In addition, HRQoL improved over time in all certolizumab pegol groups, irrespective of baseline CRP levels.  Emotional well-being improved throughout the study for patients receiving certolizumab pegol 400 mg.  This improvement was significantly greater than for patients receiving placebo at all time points.  In addition, systemic symptoms improved more in patients receiving certolizumab pegol 400 mg than in those receiving placebo at weeks 4, 8, 10, and 12 and approached statistical significance at week 2.  The authors concluded that certolizumab pegol 400 mg improved health-related quality of life in patients with moderate-to-severe Crohn's disease.

A review of the evidence for targeted immunomodulators by the Drug Effectiveness Review Project (DERP) (Thaler, et al., 2012) identified no head-to-head trials providing direct evidence on the comparative efficacy of targeted immune modulators for Crohn’s disease. The review found that the general efficacy of certolizumab pegol, adalimumab, infliximab, and natalizumab for the treatment of moderate to severe Crohn’s disease was supported by several good to fair randomized controlled trials and meta-analyses including 6901 patients. In efficacy trials 26% to 57% of patients treated with targeted immune modulators achieved a Crohn’s Disease Activity Index remission (CDAI <150), compared with 12% to 30% of patients on placebo.

Psoriasis

An UpToDate review on “Treatment of psoriasis” (Feldman, 2020) states that biologic tumor necrosis factor (TNF)-alpha inhibitors utilized for psoriasis include certolizumab pegol.  In 2018, the FDA approved certolizumab pegol for the treatment of adults with moderate to severe psoriasis who are candidates for systemic therapy or phototherapy.

Psoriatic Arthritis

Rozenblit and Lebwohl (2009) stated that the prevalence of psoriasis is estimated to be 2.2 % in the United States, and 6 to 39 % of patients with psoriasis also develop psoriatic arthritis.  New advances have been made in developing treatment options.  A new human TNF-alpha antibody, golimumab, has been shown to significantly improve symptoms of psoriatic arthritis.  In addition, clinical trials of certolizumab pegol show promising results for treating rheumatoid arthritis and suggest that it may be applicable for treating psoriasis and psoriatic arthritis in the future.  New biological therapies also include antibodies to interleukin-12 and interleukin-23.  Phase II studies suggest that ustekinumab is effective in alleviating symptoms of psoriasis and psoriatic arthritis.  However, longer studies with radiographical evaluation will be required before their impact on joint destruction can be assessed.  In a review on the treatment of peripheral arthritis in psoriatic arthritis, Soriano and Rosa (2009) noted that among new drugs, evidence of efficacy has already been published with regard to golimumab and ustekimumab; results are forthcoming from trials with abatacept, certolizumab pegol, and rituximab.  Furthermore, Farhi and Dupin (2009) stated that new biological therapies under investigation in the treatment of psoriasis include certolizumab, golimumab, and ustekinumab.

Certolizumab has been approved by the FDA for use in adults with active psoriatic arthritis (UCB, 2013). FDA approval of Cimzia for active psoriatic arthritis was based on data from the RAPIDTM-PsA study, an ongoing, phase 3, multicenter, randomized, double-blind, placebo-controlled trial designed to evaluate the efficacy and safety of certolizumab pegol in 409 patients with active and progressive adult onset psoriatic arthritis. Patients received a loading dose of certolizumab 400 mg at weeks 0, 2 and 4 or placebo, followed by either certolizumab 200 mg every other week, certolizumab 400 mg every 4 weeks, or placebo every other week.  Patients were evaluated for signs and symptoms of psoriatic arthritis using the ACR20 response at week 12 and for structural damage using the modified Total Sharp Score (mTSS) at week 24. 

ACR20, 50, and 70 response rates at weeks 12 and 24 were higher for each certolizumab dose group relative to placebo (UCB, 2013). Patients treated with certolizumab 200 mg every other week demonstrated greater reduction in radiographic progression compared with placebo-treated patients at week 24, as measured by change from baseline in total modified mTSS Score. Patients treated with certolizumab 400 mg every four weeks did not demonstrate greater inhibition of radiographic progression at week 24, compared with placebo-treated patients. Treatment with certolizumab also resulted in improvement in skin manifestations in patients with psoriatic arthritis. However, the safety and efficacy of certolizumab in the treatment of patients with plaque psoriasis has not been established.

Adverse events occurred in 62% of patients in the certolizumab group (combined dose) compared to 68% of patients in the placebo group (UCB, 2013). Serious adverse events occurred in 7% of patients in the certolizumab group (combined dose) compared to 4% of patients in the placebo group. According to the manufacturer, the safety profile for patients with psoriatic arthritis treated with certolizumab was similar to the safety profile seen in patients with rheumatoid arthritis and in patients with previous experience with certolizumab.

Rheumatoid Arthritis

Certolizumab pegol was approved by the FDA on April 24, 2009 for adults with moderately-to-severely active RA.  It can be administered as combination therapy with methotrexate (MTX) or as monotherapy.  The recommended dose for patients with moderately-to-severely active RA is 400 mg initially and at weeks 2 and 4, followed by 200 mg every other week.  For maintenance dosing, 400 mg every 4 weeks can be considered.  It is self-administered by subcutaneous injection.  According to the prescribing information, certolizumab pegol should not be used in combination with biological disease-modifying antirheumatic drugs (DMARDs) or other TNF blocker therapies.

The FDA approval of Cimzia for RA was based on data from 4 multi-center placebo-controlled phase III trials, involving more than 2,300 patients aged 18 years or older with moderately-to-severely active RA.  Patients who received certolizumab pegol together with MTX, experienced a significant reduction in the signs and symptoms of RA at week 24 with some showing clinical responses within 1 to 2 weeks, compared with MTX alone.  Additionally, radiographic data showed certolizumab pegol, together with MTX, inhibited progression of joint damage, with a significantly smaller change from baseline in modified Total Sharp Score (TSS) at 24 and 52 weeks of treatment, compared with MTX alone (p < 0.001).

The DERP review (Thaler, et al., 2012) found good to fair evidence from meta-analyses and large randomized controlled trials that certolizumab pegol, abatacept, adalimumab, anakinra, etanercept, golimumab, infliximab, rituximab, and tocilizumab are statistically significantly more efficacious than placebo for the treatment of rheumatoid arthritis. The review stated that data were too heterogeneous to conduct indirect comparisons of certolizumab pegol with other targeted immune modulators for rheumatoid arthritis.

Keystone et al (2008) evaluated the safety and effectiveness of 2 dosage regimens of certolizumab pegol as adjunctive therapy to MTX in patients with active RA who had an inadequate response to MTX therapy alone.  In this 52-week, phase III, multi-center, randomized, double-blind, placebo-controlled, parallel-group trial, 982 patients were randomized 2:2:1 to receive treatment with 400 mg of certolizumab pegol as an initial dosage and at weeks 2 and 4, with a subsequent dosage of 200 mg or 400 mg given every 2 weeks, plus MTX, or placebo plus MTX.  Co-primary endpoints were the response rate at week 24 according to the American College of Rheumatology 20 % criteria for improvement (ACR20) and the mean change from baseline in the modified TSS at week 52.  At week 24, ACR20 response rates using non-responder imputation for the certolizumab pegol 200-mg and 400-mg groups were 58.8 % and 60.8 %, respectively, as compared with 13.6 % for the placebo group.  Differences in ACR20 response rates versus placebo were significant at week 1 and were sustained to week 52 (p < 0.001).  At week 52, mean radiographic progression from baseline was reduced in patients treated with 200 mg of certolizumab pegol (0.4 Sharp units) or 400 mg (0.2 Sharp units) as compared with that in placebo-treated patients (2.8 Sharp units) (p < 0.001 by rank analysis).  Improvements in all ACR core set of disease activity measures, including physical function, were observed by week 1 with both certolizumab pegol dosage regimens.  Most adverse events were mild or moderate.  The authors concluded that 200 mg or 400 mg of certolizumab pegol plus MTX resulted in a rapid and sustained reduction in RA signs and symptoms, inhibited the progression of structural joint damage, and improved physical function as compared with placebo plus MTX treatment in RA patients with an incomplete response to MTX.

Smolen et al (2009) reported the safety and efficacy of certolizumab pegol plus MTX in a randomized controlled trial (RAPID 2 study).  Patients (n = 619) were randomized 2:2:1 to 400 mg of certolizumab pegol at weeks 0, 2 and 4 followed by 200 mg or 400 mg of certolizumab pegol plus MTX, or placebo plus MTX, every 2 weeks for 24 weeks.  The primary endpoint was ACR20 response at week 24.  Secondary endpoints included ACR50 and ACR70 responses, change from baseline in modified TSS Score, ACR core set variables and physical function.  The authors reported that significantly more patients in the 200 mg and 400 mg certolizumab pegol groups achieved an ACR20 response versus placebo (p < or = 0.001); rates were 57.3 %, 57.6 % and 8.7 %, respectively.  Certolizumab pegol significantly inhibited radiographic progression; mean changes from baseline in modified TSS at week 24 were 0.2 and -0.4, respectively, versus 1.2 for placebo (rank analysis p < or = 0.01).  Certolizumab pegol-treated patients reported rapid and significant improvements in physical function versus placebo; mean changes from baseline in the Disability Index of the Health Assessment Questionnaire (HAQ DI) at week 24 were -0.50 and -0.50, respectively, versus -0.14 for placebo (p < or = 0.001).  Most adverse events were mild or moderate, with low incidence of withdrawals due to adverse events.  Five patients developed tuberculosis.  The authors concluded that certolizumab pegol plus MTX were more efficacious than placebo plus MTX.

Fleischmann et al (2009) evaluated the safety and efficacy of certolizumab pegol in a randomized, double-blind, placebo-controlled study (FAST4WARD study) in RA patients (n = 220) previously failing one or more DMARDs.  Patients were randomized 1:1 to receive 400 mg of subcutaneous certolizumab pegol (n = 111) or placebo (n = 109) every 4 weeks.  The primary endpoint was the ACR20 response at week 24.  Secondary endpoints included ACR50/70 response, ACR component scores, 28-joint Disease Activity Score Erythrocyte Sedimentation Rate 3 (DAS28(ESR)3), patient-reported outcomes (including physical function, HRQoL, pain and fatigue) and safety.  At week 24, the ACR20 response rates were 45.5 % for 400 mg of certolizumab pegol every 4 weeks versus 9.3 % for placebo (p < 0.001).  Differences for certolizumab pegol versus placebo in the ACR20 response were statistically significant as early as week 1 through week 24 (p < 0.001).  Significant improvements in ACR50, ACR components, DAS28(ESR)3 and all patient-reported outcomes were also observed early with certolizumab pegol and were sustained throughout the study.  Most adverse events were mild or moderate and no deaths or cases of tuberculosis were reported.  The authors concluded that 400 mg of certolizumab pegol monotherapy every 4 weeks effectively reduced the signs and symptoms of active RA in patients previously failing one or more DMARDs compared with placebo, and demonstrated an acceptable safety profile.

The American College of Rheumatology (ACR) conducted a systematic review to synthesize the evidence for the benefits and harms of various treatment options. Their goal was to develop evidence-based, pharmacologic treatment guideline for rheumatoid arthritis. The 2015 American College of Rheumatology Guidelines for the Treatment of Rheumatoid Arthritis provided “strong” recommendations for established RA and symptomatic early RA.

For established RA, the guidelines state “if the disease activity is low, in patients who have never taken a DMARD, the recommendation is to use DMARD monotherapy (methotrexate preferred) over TNFi”. “If disease activity remains moderate or high despite DMARD monotherapy, the recommendation is to use combination traditional [conventional] DMARDs or add a TNFi or a non-TNF biologic or tofacitinib (all choices with or without methotrexate, in no particular order of preference), rather than continuing DMARD monotherapy alone”. Recommendations for patients with symptomatic early RA state that “if disease activity is low, in patients who have never taken a DMARD, use DMARD monotherapy (methotrexate preferred) over double or triple therapy”.  “If disease activity remains moderate or high despite DMARD monotherapy (with our without glucocorticoids), use combination DMARDs or a TNFi or a non-TNF biologic (all choices with our without methotrexate, in no particular order of preference), rather than continuing DMARD monotherapy alone”. A strong recommendation means that the panel was confident that the desirable effects of following the recommendation outweigh the undesirable effects (or vice versa), so the course of action would apply to most patients, and only a small proportion would not want to follow the recommendation (Singh et al., 2016).

Uveitis

Rifkin et al (2013) discussed the differences in the mechanism of action, route of administration, indication, and effectiveness of TNF inhibitors used in the treatment of ocular inflammation.  A review of the literature in the PubMed, Medline, and Cochrane databases was conducted to identify clinical trials, comparative studies, case series, and case reports describing the use of tumor necrosis factor inhibitors in uveitis therapy.  The search was limited to primary reports published in English with human subjects from 1990 to the present, yielding 5,238 manuscripts.  In addition, referenced articles from the initial searches were hand searched to identify additional relevant reports.  After title and abstract selection, duplicate elimination, and manual search, a total of 69 papers were selected for analysis.  Exclusion criteria included review articles and case reports on the effectiveness of adalimumab, etanercept, and infliximab.  Manuscripts with fewer than 20 study subjects were excluded if other larger studies existed on the use of the same drug for a particular indication.  Studies with less than 6 months of patient follow-up were also excluded, except in the case where no other data were available.  Articles meeting these criteria were then reviewed by the 3 authors for inclusion in this review.  Tumor necrosis factor inhibitors have been shown to decrease inflammation associated with a number of rheumatologic conditions.  Three of the 5 commercially available TNF inhibitors – adalimumab, etanercept, and infliximab -- have been studied for their effectiveness in treatment of ocular inflammation.  Etanercept appears to be inadequate in controlling ocular inflammation and is not recommended for the treatment of uveitis.  Adalimumab and infliximab, however, have shown encouraging results in multiple trials.  Serious potential side effects such as infection, including re-activation of latent tuberculosis, malignancy, and demyelinating disease, may limit the use of TNF inhibitors in uveitis.  Proper screening of patients prior to initiating these therapies may decrease these risks.  The authors concluded that early success with adalimumab and infliximab has paved the way for new TNF inhibitors and other corticosteroid-sparing drugs to emerge in the treatment of ocular inflammation.  They stated that future studies are on the horizon to determine the long-term safety and effectiveness of newer TNF inhibitors such as certolizumab and golimumab.

Sanchez-Cano et al (2013) stated that TNF-alpha plays a central role in both the inflammatory response and that of the immune system.  Thus, its blockade with the so-called anti-TNF agents (infliximab, etanercept, adalimumab, certolizumab pegol, and golimumab) has turned into the most important tool in the management of a variety of disorders, such as rheumatoid arthritis, spondyloarthropathies, inflammatory bowel disease, and psoriasis.  Nonetheless, theoretically, some other autoimmune disorders may benefit from these agents.  These investigators reviewed these off-label uses of anti-TNF blockers in 3 common conditions:

1. Behcet's disease,
2. sarcoidosis, and
3. non-infectious uveitis.

They noted that due to the insufficient number of adequate clinical trials and consequently to their lower prevalence compared to other immune disorders, this review was mainly based on case reports and case series. 

Measurements of Certolizumab Level and Certolizumab Antibody Level

Gehin and colleagues (2019) identified a therapeutic target interval for certolizumab pegol drug levels and examined the influence of anti-drug antibodies (ADAs) in patients with inflammatory joint diseases (IJDs).  Certolizumab pegol and ADA levels were measured in serum samples collected after 3 months of certolizumab pegol treatment in 268 patients with IJDs (116 axSpA, 91 RA, and 61 PsA) in the NOR-DMARD study.  Therapeutic response was defined by ASDAS clinically important improvement in axSpA, European League Against Rheumatism (EULAR) good/moderate response in RA, and improvement in 28-joint DAS of greater than or equal to 0.6 in PsA.  Serum drug levels and ADAs were analyzed using automated in-house assays.  Certolizumab pegol serum levels varied considerably between individuals (median inter-quartile range [IQR] 32.9 (17.3 to 43.9) mg/L).  Certolizumab pegol level of greater than or equal to 20 mg/L was associated with therapeutic response for the total IJD population, with odds ratio (OR) 2.3 (95 % CI: 1.2 to 4.5, p = 0.01) and OR 1.9 (95 % CI: 1.0 to 3.5, p = 0.05) after 3 and 6 months of treatment, respectively.  For individual diagnoses, this association was most consistent for axSpA, with OR 3.4 (95 % CI: 1.0 to 11.1, p < 0.05) and OR 3.3 (95 % CI: 1.0 to 10.8, p < 0.05), respectively.  Certolizumab pegol level of greater than 40 mg/L was not associated with any additional benefit for any of the diagnoses; ADAs were detected in 6.1 % (19/310) of samples and were associated with low certolizumab pegol levels (p < 0.01).  The authors concluded that serum certolizumab pegol levels of 20 to 40 mg/L were associated with therapeutic response in IJDs.  These researchers stated that this study was the 1st to show this association in axSpA and PsA patients.  They stated that these findings suggested a possible benefit of therapeutic drug monitoring  (TDM)in patients with IJD on certolizumab pegol treatment; however, the clinical significance of tailoring TNF inhibitor (TNFi) treatment in IJDs by TDM should be further examined in randomized controlled trials (RCTs).  Moreover, these researchers stated that the lack of data on body weight and of more extensive joint counts in PsA patients was a drawback of this study.

Mehta and Manson (2020) noted that TNFis have revolutionized the management of RA, however despite considerable progress, only a small proportion of patients maintain long-term clinical response.  Selection of, and switching between, biologics is mainly empirical, experiential, and not evidence-based.  Most biopharmaceutical proteins (BP) could induce an immune response against the foreign protein component.  Immunogenicity and the development of anti-drug antibodies (ADAs) is considered one of the main reasons for loss of therapeutic efficacy (secondary failure).  ADAs may neutralize and/or promote clearance of circulating BP with resultant low serum drug levels, loss of clinical response, poor drug survival and adverse events (AEs), such as infusion reactions.  ADA identification is technically difficult and not standardized, making interpretation of immunogenicity data from published clinical studies challenging.  Trough TNFi drug levels correlate with clinical outcomes, exhibiting a "concentration-response" relationship.  Measurement of ADA and drug levels may improve patient care and improve cost-effectiveness of BP use.  However, in the absence of clinically-validated, reliable assays and consensus guidelines, TDM and immunogenicity testing have not been widely adopted in routine clinical practice in rheumatology.  These researchers stated that prospective, longitudinal studies of BP-naïve patients may provide mechanistic information and address a critical unanswered question -- why BPs are immunogenic in some patients, but tolerogenic in others.  Prediction of immunogenicity may allow mitigation and management strategies to be implemented to prevent or minimize the generation of ADAs.  Other strategies to personalize biologic selection, include pharmacogenetic testing to identify genetic factors that may predict lack of response to, or toxicities from, TNFi.  These investigators stated that further research is needed to develop standardized, clinically-validated assays for both drug and ADA testing.  These tests could then be incorporated into evidence-based guidelines to optimize treatment-decisions along the patient pathway: for patients with active disease about to start treatment, not responding to treatment (primary or secondary failure) or for those in remission, to permit drug tapering strategies.  Taken together this may help to improve the safety profile, long-term efficacy, and cost-effectiveness of BPs.
