Clinical Edge Journal Scan Commentary

Research continues to demonstrate the benefits of glucagon-like peptide-1 receptor (GLP-1R) agonists or co-agonists for type 2 diabetes (T2D). Arslanian and the AWARD-PEDS investigators have published the results of a randomized controlled trial comparing once-weekly dulaglutide vs.placebo in youths between 10 and17 years of age with T2D. A1c was reduced by 1.2% with 0.75 mg dulaglutide and by 1.5% with a 1.5 mg dose, compared with placebo. Of note, there was no significant weight difference between dulaglutide and placebo, similar to what has been found with liraglutide and extended-release exenatide in similar populations. This is also contrary to the weight loss that is found with GLP-1R agonists in adult studies. While the GLP-1R agonist class provides a nice glycemic benefit in youth with T2D, it remains perplexing as to why weight loss has not been demonstrated in clinical trials.

In the SURPASS trials of the GLP-1/gastric inhibitory polypeptide (GIP) receptor co-agonist tirzepatide, there was robust A1c lowering and weight loss among individuals with T2D. A meta-analysis published by Karagiannis and colleagues of seven tirzepatide trials has shown dose-dependent superiority for A1c and weight compared withplacebo, GLP-1R agonists, and basal insulin. Gastrointestinal side effects were similar to what we have come to expect with GLP-1R agonist–based therapies. Tirzepatide, recently approved by the US Food and Drug Administration (FDA) for the treatment of T2D, is a welcome addition to the pharmacotherapy toolkit.

In the SURPASS-2 study, all doses of tirzepatide were superior to 1 mg semaglutide for both A1c and body weight reduction. Following the recent approval of 2 mg semaglutide by the FDA for the management of T2D, Vadher and colleagues explored how tirzepatide compares with 2 mg semaglutide via an indirect treatment comparison. Using data from the SUSTAIN-FORTE and SURPASS-2 trials, these authors found that A1c and weight reductions were significantly greater for 10 and 15 mg tirzepatide vs 2 mg semaglutide and similar for 5 mg tirzepatide vs 2 mg semaglutide. In the absence of a head-to-head trial, this analysis suggests greater efficacy with tirzepatide compared with high-dose semaglutide in T2D.

Continuous glucose monitoring (CGM) provides information about glycemia that is not available with A1c and capillary glucose monitoring. The coefficient of variation (CV) calculated from CGM is a good measure of glycemic variability, with a goal of ≤36%. There are inconsistent data for the association of CV with microvascular or macrovascular complications and very little study of the relationship between CV and long-term mortality. Mo and colleagues investigated the association between short-term glycemic variability measured by CV and all-cause mortality in a prospective study of 1839 individuals with T2D and a well-controlled glucose profile monitored by CGM. After about 7 years of follow-up, a greater baseline CV was associated with an increased risk for all-cause mortality, with a greater than twofold risk fo rmortality with a baseline CV of >35% compared witha baseline CV of ≤20%. This study suggests that clinicians should pay attention when CV is high, even with otherwise good glycemic control. With the expanding use of CGM, long-term intervention studies are needed to determine the role of glycemic variability(CV) in the development of complications and hard outcomes.

Advanced targeted therapies have proven safety and efficacy over conventional therapies, often dramatically improving signs and symptoms. However, it is also desirable that such expensive therapies also show benefit in other outcomes, such as work productivity and quality of life. To evaluate work productivity and daily activity impairment and health-related quality of life in patients with inflammatory arthritis (rheumatoid arthritis, n = 95; PsA, n = 69, and axial spondyloarthritis, n = 95) treated with golimumab, Dejaco and colleagues conducted a prospective, multicenter study in Austria. A total of 110 of these patients were followed for 24 months. At 24 months after golimumab initiation, there was significant improvement in total work productivity, presenteeism, activity impairment, and quality-of-life scores. Thus, golimumab, in addition to reducing disease activity, improved work productivity, activity, and health-related quality of life in patients with inflammatory arthritis, including PsA.

Cardiovascular disease (CVD) remains a major comorbidity in patients with PsA. This observation was once again confirmed in an observational, cross-sectional, case-control study including 207 patients with PsA and 414 matched controls from France. Degboe and colleagues demonstrated that patients with PsA had a higher prevalence of cardiovascular events and cardiovascular risk factors, such as high body mass index, triglyceride level, and hypertension, compared with controls. The proportion of patients with PsA who were estimated to have very high cardiovascular risk factors (≥ 10%) increased when SCORE (European Society of Cardiology Systematic Coronary Risk Evaluation) and QRISK2 (British Heart Foundation) equations considered the additional risk attributable to PsA. However, risk predictions scores such as SCORE and QRISK2 perform poorly in patients with PsA. To identify novel inflammatory and metabolic parameters associated with cardiovascular disease, Schwartz and colleagues looked at ¹⁸F-fluorodeoxyglucose (FDG) PET-CT uptake in a cross-sectional analysis of a prospective study including 39 patients with biologic-treatment-naive PsA and 56 age-sex matched controls without PsA. They found that coronary artery disease (CAD) was significantly associated with visceral adiposity and FDG uptake in the bone marrow, liver, spleen, and subcutaneous adipose tissue. Thus, inflammatory and metabolic parameters, including visceral adiposity, potentially contribute to subclinical CAD in patients with PsA and may in the future be used to refine CVD risk and be targets for CAD preventive treatments.

 The study by D'Amico and colleagues underscores the importance of using biologic therapies early in the postoperative course to prevent endoscopic recurrence. Patients who require surgery should initiate biologic therapy as soon as they have completed postoperative healing. This will help prevent a recurrence of their Crohn's disease and limit the need for subsequent surgery in the future. Proactive monitoring for postoperative recurrence and prompt management of any inflammation identified is vital in improving long-term outcomes.

 Meanwhile, Rosiou and colleagues highlight the importance of communication with the entire care team regarding the management of IBD flares. Proactive patient education about notifying the primary gastroenterology provider if they experience flare symptoms can help prevent inappropriate or excess steroid exposure. Steroid-sparing strategies for the induction and maintenance of IBD remission are pivotal in preventing side effects and long-term complications of steroid exposure. Steroids should be used as a short-term therapy while bridging to a safe and appropriate maintenance regimen.

Liver transplantation cures both HCC and the underlying cirrhosis; however, tumor progression while the patient is on the waiting list is an ongoing concern. Couillard and colleagues reported a retrospective study of 88 patients with HCC who underwent percutaneous microwave ablation for 141 tumors while on the liver transplant list. The median follow-up was 61 months. Seventy-one patients (80.7%) underwent liver transplantation after a median wait time of 8.5 months. No tumor seeding was identified. Seventeen patients (19.3%) were removed from the waitlist, four (4.5%) of whom because of tumor progression outside of the Milan criteria. A total of five of 71 (7.0%) patients had posttransplant recurrence of HCC and all died during this time. The 5-year overall survival (OS) following liver transplantation was 76.7% and the disease-specific survival after transplantation was 89.6%. The authors concluded that microwave ablation is a safe and effective treatment that bridges patients to successful transplantation.

Radiation segmentectomy is performed by the administration of radioactive yttrium (⁹⁰Y)-bound microspheres transarterially to the segment of liver containing an unresected tumor. Kim and colleagues described the results of a prospective trial that evaluated the efficacy of radiation segmentectomy with curative intent in patients with Child-Pugh score A–B7 and small (< 3 cm), unresectable HCC, where the tumors were in a location unsuitable for ablation. Of the 44 individuals assessed for eligibility, 29 patients were included in the study. A complete response was observed in 24 (83%) patients, and a partial response was observed in 5 (17%) patients. All patients had an initial objective tumor response, and 26 (90%) had a sustained complete response during 24 months of clinical follow-up. The treatment was well tolerated, with four (14%) patients having grade 3 leukopenia and two (7%) having grade 3 thrombocytopenia. The authors concluded that radiation segmentectomy should be investigated further as a potentially curative option for patients with HCC.

Portal vein thrombosis (PVT) has been considered a contraindication to transarterial chemoembolization (TACE) due to the concern for inadvertent liver ischemia if the hepatic artery becomes obstructed. Several studies have demonstrated that this risk is low. Stereotactic body radiation therapy (SBRT) is used to effectively target HCC (especially when there is a portal vein tumor) while minimizing collateral damage to the liver. Zhang and colleagues performed a meta-analysis of nine studies totaling 938 patients who had HCC with tumor PVT. Of those, 483 received either SBRT or TACE, and 455 were treated with both TACE and SBRT. There were 255 events reported in the monotherapy groups and 174 events in the combination groups. Following statistical analyses of all available data, the authors concluded that SBRT plus TACE yielded significantly higher 1-year OS (RR [relative risk] 1.52; 95% CI 1.33-1.74), 2-year OS (RR 2.00; 95% CI 1.48-2.70), and a lower progressive disease rate (RR 0.45; 95% CI 0.26-0.79) than monotherapy. The combination treatment was both safe and effective.

Radiation segmentectomy is performed by the administration of radioactive yttrium (⁹⁰Y)-bound microspheres transarterially to the segment of liver containing an unresected tumor. Kim and colleagues described the results of a prospective trial that evaluated the efficacy of radiation segmentectomy with curative intent in patients with Child-Pugh score A–B7 and small (< 3 cm), unresectable HCC, where the tumors were in a location unsuitable for ablation. Of the 44 individuals assessed for eligibility, 29 patients were included in the study. A complete response was observed in 24 (83%) patients, and a partial response was observed in 5 (17%) patients. All patients had an initial objective tumor response, and 26 (90%) had a sustained complete response during 24 months of clinical follow-up. The treatment was well tolerated, with four (14%) patients having grade 3 leukopenia and two (7%) having grade 3 thrombocytopenia. The authors concluded that radiation segmentectomy should be investigated further as a potentially curative option for patients with HCC.

Portal vein thrombosis (PVT) has been considered a contraindication to transarterial chemoembolization (TACE) due to the concern for inadvertent liver ischemia if the hepatic artery becomes obstructed. Several studies have demonstrated that this risk is low. Stereotactic body radiation therapy (SBRT) is used to effectively target HCC (especially when there is a portal vein tumor) while minimizing collateral damage to the liver. Zhang and colleagues performed a meta-analysis of nine studies totaling 938 patients who had HCC with tumor PVT. Of those, 483 received either SBRT or TACE, and 455 were treated with both TACE and SBRT. There were 255 events reported in the monotherapy groups and 174 events in the combination groups. Following statistical analyses of all available data, the authors concluded that SBRT plus TACE yielded significantly higher 1-year OS (RR [relative risk] 1.52; 95% CI 1.33-1.74), 2-year OS (RR 2.00; 95% CI 1.48-2.70), and a lower progressive disease rate (RR 0.45; 95% CI 0.26-0.79) than monotherapy. The combination treatment was both safe and effective.

Liver transplantation cures both HCC and the underlying cirrhosis; however, tumor progression while the patient is on the waiting list is an ongoing concern. Couillard and colleagues reported a retrospective study of 88 patients with HCC who underwent percutaneous microwave ablation for 141 tumors while on the liver transplant list. The median follow-up was 61 months. Seventy-one patients (80.7%) underwent liver transplantation after a median wait time of 8.5 months. No tumor seeding was identified. Seventeen patients (19.3%) were removed from the waitlist, four (4.5%) of whom because of tumor progression outside of the Milan criteria. A total of five of 71 (7.0%) patients had posttransplant recurrence of HCC and all died during this time. The 5-year overall survival (OS) following liver transplantation was 76.7% and the disease-specific survival after transplantation was 89.6%. The authors concluded that microwave ablation is a safe and effective treatment that bridges patients to successful transplantation.

First, Blauvelt and colleagues presented findings from the ongoing LIBERTY AD PED-OLE open-label extension study, including 294 adolescents with moderate to severe AD who participated in previous dupilumab trials. Patients received a maintenance dose of 300 mg dupilumab every 4 weeks, which was increased to a weight-based every-other-week regimen if there was inadequate clinical response to every-4-week dosing. They found that 81.2% of patients achieved an Eczema Area and Severity Index (EASI-75) response at week 52 with every-4-week dosing, and 51.9% of patients at week 48 after switching to every-2-week doing. These results indicate that some adolescents may be able to maintain clinical efficacy with monthly dosing, while others may require every-2-week dosing. Of note, no new safety signals emerged during the study and most adverse events were mild to moderate.

Two more studies were published showing real-world effectiveness and safety of dupilumab. Eichenfield and colleagues performed a retrospective, observational study of the effectiveness of dupilumab after 4 months of treatment using data from national electronic medical records in adults with moderate-to-severe AD. They found that most patients achieved at least a one-grade (81.8%) or two-grade (62.8%) improvement of their Investigator's Global Assessment (IGA) scores, with 42.8% achieving IGA scores of 0/1 (clear/minimal). There were also significant improvements in itch and lesional extent. The results were remarkably similar to those observed in the phase 3 clinical trial program of dupilumab in adults with moderate-to-severe AD.

Bagel and colleagues published baseline characteristics of patients enrolled in the ongoing PROSE longitudinal real-world registry of dupilumab use in adults with moderate-to-severe AD. Almost half of the patients (49.5%) previously received systemic medications, including 41.0% with systemic corticosteroids, 16.8% with nonsteroidal systemic therapies, such as cyclosporine and methotrexate, and 10.2% with phototherapy. This result indicates that many medical professionals are not using dupilumab as a first-line systemic therapy, despite its established record on safety and efficacy. It appears that many clinicians prefer a short-term treatment regimen, such as systemic corticosteroids, prior to initiating long-term treatment with dupilumab. However, short-term treatment approaches are not ideal for this chronic and often lifelong disease. It is important that clinicians develop appropriate long-term treatment approaches for atopic dermatitis in general, regardless of any specific therapy.

On a different research note, my research group just published the results of a longitudinal dermatology practice–based study of depressive symptoms in 695 adults with AD over time.¹ We found that approximately half of the patients experienced fluctuating severity of depressive symptoms, and 45.65% experienced persistent severity of depression. Severity of AD lesions and itch were the strongest predictors of more severe symptoms of depression. Perhaps most fascinating about this research was that symptoms of depression improved dramatically in a very large subset of patients who experienced reduced AD severity with standard-of-care treatment. These results highlight the broader impacts of AD on mental health, which were recently recognized by the American Academy of Dermatology's guideline update on AD comorbidities.² Moreover, our study demonstrated that many of these mental health impacts were modifiable with optimized AD therapy.

Next, a retrospective analysis compared adjuvant capecitabine or capecitabine + oxaliplatin (CapeOX) for resected stage II-III colorectal cancer in 606 patients. Fifty-four of these patients were taking a proton pump inhibitor (PPI) as well. The authors found that concomitant use of a PPI with capecitabine monotherapy led to shorter relapse-free survival (adjusted hazard ratio, 2.48; P = .013) compared with those not taking a PPI. Interestingly, the effect on RFS was not observed in patients receiving CapeOX. A proposed mechanism for this finding is that the increased pH in PPI-treated stomachs decreases dissolution of the capecitabine tablet. Certainly, direct observation would be required to prove this, but these data alone may be enough for oncologists to think twice before prescribing capecitabine to patients who must remain on a PPI.

Lastly, a well-done analysis from the Nurses' Health Study found that higher intake of sugar-sweetened beverages and total fructose was associated with increased incidence of and mortality from proximal colon cancer, but interestingly not distal colon or rectal cancers. The hazard ratios for both the incremental incidence of proximal colon cancer for intake of one serving of sugar-sweetened beverage per day and for 25 g/day of fructose were 1.18 (P_trend = .02), and the hazard ratios for mortality were 1.39 (P_trend = .002) and 1.42 (P_trend = .003), respectively. I am often asked by my patients what, if any, utility there might be in limiting sugar intake when undergoing cancer treatment. This study provides the basis for an answer that is more than just hand-waving.

Predicting severe disease is of great importance in rheumatoid arthritis (RA), ideally to establish which poor prognostic factors allow for early aggressive and targeted treatment for a subset of patients. In a post hoc analysis of the AGREE study by Durez and colleagues, 509 treatment-naive patients randomized to either methotrexate or methotrexate with abatacept were evaluated for predictors of joint damage and disease activity. Baseline swelling in the knee, temporomandibular joint (TMJ), elbow, and wrist was correlated with severe disease activity as well as tender and swollen joint counts, whereas baseline swelling at the second metacarpophalangeal joint was correlated with erosive disease. Overall, remission rates were better in patients with baseline wrist, TMJ, elbow, and knee swelling treated with combination therapy vs methotrexate alone, suggestive of a better response to more aggressive therapy. Further studies of patients with RA with poor prognostic factors would be helpful.

Laboratory biomarkers can also serve as prognostic indicators for patients with RA. Based in part on the association of obesity and lower rates of remission in people with RA, Baker and colleagues investigated the possible association of adipocytokines and disease activity in a cohort study of over 1200 patients with Disease Activity Score for Rheumatoid Arthritis (DAS28) > 3.2 enrolled in the Veterans Affairs RA registry. Of these, about 800 achieved low disease activity while the remainder did not. Interestingly, obesity was not a baseline characteristic associated with disease activity, though chronic obstructive pulmonary disease, heart failure, and mood disorders were. Baseline adipocytokine levels on average did not differ between the two groups, though higher baseline adiponectin and leptin levels (based on quartile) were associated with a lower likelihood of achieving low disease activity. Interestingly, this change did not increase progressively with higher quartile. Because these are baseline levels and were not tracked prospectively with medication use, it is difficult to assess the importance of this finding. The association may not reflect a causative relationship but may be affected by medications or disease duration. However, it appears worthwhile investigating in therapy-naive patients as well as those being observed with treatment.

Finally, with respect to novel therapeutic regimens, Fleischmann and colleagues report the results of a multicenter randomized clinical trial of a Bruton tyrosine kinase inhibitor, elsubrutinib, alone or in combination with the Janus kinase (JAK) inhibitor upadicitinib in the treatment of 242 patients with RA. At the end of 12 weeks, DAS28 with C-reactive protein scores were not measurably lower in patients treated with elsubrutinib at different doses. In addition, patients receiving the combination therapy of 15 mg upadicitinib with the highest dose of elsubrutinib (60 mg) did not have greater DAS28 improvement than patients treated with upadicitinib alone, suggesting a lack of synergistic effect. Short-term safety data does not suggest significant differences. Though this combination is also being investigated in systemic lupus erythematosus, it is not clear that the combination of two targeted synthetic disease-modifying antirheumatic drugs is feasible in RA, nor that long-term safety concerns would make it advisable.

Real-World Retrospective Study Suggests Inferior Outcomes to First-Line Systemic Treatment in Advanced NFE2L2 and KEAP1 Mutant Squamous NSCLC

Targeted therapies against oncogene-driven lung cancer, such as epidermal growth factor receptor (EGFR) and anaplastic lymphoma kinase (ALK), in lung adenocarcinoma have revolutionized lung cancer treatment. However, there are no US Food and Drug Administration–approved targeted therapies for commonly occurring mutations in advanced squamous non–small cell lung cancer (NSCLC).

NFE2L2 and KEAP1 mutations are molecular alterations that occur in about 25%-30% of squamous NSCLC. NFE2L2 encodes for the NRF2 transcription factor that is involved in the oxidative stress pathway and KEAP1 encodes for the KEAP1 protein, which is the negative regulator of NFE2L2.¹ When the NRF2-KEAP1 signaling pathway is disrupted, there is persistent activation of NRF2, which promotes cell proliferation and carcinogenesis and may contribute to resistance to cancer-directed treatments. Previous retrospective studies suggest that patients with lung cancers harboring NFE2L2 and KEAP1 mutations have a poorer prognosis and do worse with both systemic anticancer treatments and radiation.^2-5

Wu and colleagues, in a retrospective cohort study, identified 703 patients with squamous NSCLC from 2011 to 2018 who had NFE2L2 or KEAP1 mutations identified by comprehensive genomic profiling in the Flatiron Health-Foundation Medicine Clinico-Genomic Database. Real-world progression-free survival (PFS), defined as a distinct episode where the clinician concluded that there was growth or worsening of disease, was assessed by line and type of treatment, as was overall survival (OS). Patients with squamous NSCLC with NFE2L2/KEAP1 mutations had shorter real-world PFS to first-line treatment compared with patients whose tumors were wild-type for these mutations (4.54 months vs 6.25 months; P = .0027). Median OS was numerically shorter in patients with NFE2L2/KEAP1 mutations, but this was not statistically significant (13.59 vs 17.37 months; P = .41). This retrospective real-world analysis suggests that patients with squamous NSCLC and NFE2L2/KEAP1 mutations have inferior outcomes with systemic treatments and may have worsened OS; however, this was not statistically significant. Many of these patients were treated before the approval of the KEYNOTE-407 chemo-immunotherapy regimen in squamous NSCLC, so they did not have what we would consider contemporary standard treatment. Further studies are needed to evaluate the role of NRF2 activation in resistance to NSCLC treatments, and there is a need for therapeutics to target these common mutations in squamous NSCLC. Fortunately, there are current ongoing clinical trials.^[6]

Segmentectomy Is Noninferior to and Improves Overall Survival Compared With Lobectomy in Selected Cases of Small Peripheral Early-Stage NSCLC              

Lobectomy has been the standard of care for surgical treatment of early-stage NSCLC. Saji and colleagues investigated whether segmentectomy was noninferior to lobectomy in selected cases of small-sized peripheral NSCLC. This randomized, controlled, noninferiority trial was conducted at 70 institutions in Japan.

Patients with selected stage IA (American Joint Committee on Cancer [AJCC], seventh edition) NSCLC (peripheral tumors, £ 2 cm diameter, consolidation-to-tumor ratio > 0.5) were randomly assigned to undergo segmentectomy or lobectomy. The primary endpoint was OS. Pertinent secondary endpoints included postoperative respiratory function, relapse-free survival, and adverse events.

A total of 1106 patients were enrolled: 554 in the lobectomy group and 552 in the segmentectomy group. The 5-year OS was 94.3% for segmentectomy and 91.1% for lobectomy (hazard ratio 0.663; one-sided P < .001 for noninferiority; P = .0082 for superiority). In addition to the modestly improved OS observed, 5-year relapse-free survival was comparable between the groups (88% for segmentectomy and 87.9% for lobectomy). However, more local relapse was observed for segmentectomy (10.5%) than for lobectomy (5.4%) (P = .0018). Despite significantly more locoregional recurrences with segmentectomy compared with lobectomy, rates of combined distant and locoregional relapses were similar. Slightly more patients died in the lobectomy group than the segmentectomy group, and the rate of cancer-related deaths, including second primary lung cancers, was higher in the lobectomy group. Interestingly, although segmentectomy had better OS, the survival advantage was not cancer-specific.

The mechanism by which segmentectomy improved survival over lobectomy in these selected patients with small, peripheral stage IA NSCLC is still unclear. Limitations of the study included that all patients were from one geographic region (Japan) and that the study was unblinded, which can introduce bias. We await the results of CALGB 140503: A Randomized Phase III Trial of Lobectomy versus Sublobar Resection for Small (< 2cm) Peripheral Non-Small Cell Lung Cancer (NCT00499330). This study is being done in a US population and includes nonanatomic wedge in its sublobar resection cohort.

The study by Saji and colleagues suggests that surgeons should consider segmentectomy in appropriate patients (select small stage IA NSCLC [peripheral tumors, £ 2 cm diameter, consolidation-to-tumor ratio > 0.5]), based on the modest improvement in OS compared with lobectomy.

Immunotherapy Activity in Cachexic and Noncachexic Patients With Advanced NSCLC and Clinical Outcomes, by Adipose Tissue Loss on Treatment

There are emerging data that body mass index (BMI) and the presence or absence of cachexia in cancers, including NSCLC, may change the efficacy of programmed cell death-ligand 1 (PD-L1) immune checkpoint inhibitors. Nishioka and colleagues, in a single-center retrospective cohort, examined patients with advanced NSCLC (40 with cachexia and 34 without cachexia) who received PD-L1 inhibitors (pembrolizumab, nivolumab, or atezolizumab). Patients were excluded if they had poor performance status, EGFR/ALK/ROS1 oncogene drivers, unknown PD-L1 expression status, and unknown weight loss in the 6 months before immunotherapy administration. In addition to BMI, measurements of adipose tissue quantity and muscle mass were used.

The overall response rate was 28.4% in the 74 patients analyzed. Patients with cachexia had a lower overall response rate than those without cachexia (15.0% vs 44.1%; P < .05). Among the patients without cachexia, those with total adipose tissue loss had a significantly longer PFS than those with total adipose tissue maintenance (18.5 months vs 2.86 months; P = .037), including in a multivariate analyses (hazard ratio 0.34; P < .05), after adjustment for PD-L1 expression and performance status (Eastern Cooperative Oncology Group [ECOG] 0 vs. 1).

Mechanistically, a paradoxical effect of obesity on T-cell function that relates to leptin, which is secreted by adipose tissue, has been observed in preclinical studies.⁷ In a previously published study, obesity resulted in tumor progression and PD-1–mediated T-cell dysfunction, which can be overcome by PD-L1 blockade with improved clinical outcomes to these therapies in patients with obesity and cancer, including NSCLC.⁷ This "obesity paradox" may underlie some of the findings observed in Nishioka and colleagues' study. More research needs to be done regarding the activity of immune checkpoint inhibition in NSCLC as it relates to BMI, cachexia, and amount of adipose tissue.

Real-World Retrospective Study Suggests Inferior Outcomes to First-Line Systemic Treatment in Advanced NFE2L2 and KEAP1 Mutant Squamous NSCLC

Targeted therapies against oncogene-driven lung cancer, such as epidermal growth factor receptor (EGFR) and anaplastic lymphoma kinase (ALK), in lung adenocarcinoma have revolutionized lung cancer treatment. However, there are no US Food and Drug Administration–approved targeted therapies for commonly occurring mutations in advanced squamous non–small cell lung cancer (NSCLC).

NFE2L2 and KEAP1 mutations are molecular alterations that occur in about 25%-30% of squamous NSCLC. NFE2L2 encodes for the NRF2 transcription factor that is involved in the oxidative stress pathway and KEAP1 encodes for the KEAP1 protein, which is the negative regulator of NFE2L2.¹ When the NRF2-KEAP1 signaling pathway is disrupted, there is persistent activation of NRF2, which promotes cell proliferation and carcinogenesis and may contribute to resistance to cancer-directed treatments. Previous retrospective studies suggest that patients with lung cancers harboring NFE2L2 and KEAP1 mutations have a poorer prognosis and do worse with both systemic anticancer treatments and radiation.^2-5

Wu and colleagues, in a retrospective cohort study, identified 703 patients with squamous NSCLC from 2011 to 2018 who had NFE2L2 or KEAP1 mutations identified by comprehensive genomic profiling in the Flatiron Health-Foundation Medicine Clinico-Genomic Database. Real-world progression-free survival (PFS), defined as a distinct episode where the clinician concluded that there was growth or worsening of disease, was assessed by line and type of treatment, as was overall survival (OS). Patients with squamous NSCLC with NFE2L2/KEAP1 mutations had shorter real-world PFS to first-line treatment compared with patients whose tumors were wild-type for these mutations (4.54 months vs 6.25 months; P = .0027). Median OS was numerically shorter in patients with NFE2L2/KEAP1 mutations, but this was not statistically significant (13.59 vs 17.37 months; P = .41). This retrospective real-world analysis suggests that patients with squamous NSCLC and NFE2L2/KEAP1 mutations have inferior outcomes with systemic treatments and may have worsened OS; however, this was not statistically significant. Many of these patients were treated before the approval of the KEYNOTE-407 chemo-immunotherapy regimen in squamous NSCLC, so they did not have what we would consider contemporary standard treatment. Further studies are needed to evaluate the role of NRF2 activation in resistance to NSCLC treatments, and there is a need for therapeutics to target these common mutations in squamous NSCLC. Fortunately, there are current ongoing clinical trials.^[6]

Infections have long been identified as possible triggers for psoriasis and psoriatic arthritis (PsA) onset. Thrastardottir and colleagues evaluated the association between sites where the culture sample was obtained, the culture result, and pathogens and incident PsA and psoriasis. They obtained data on all samples sent for bacterial culture in the Stockholm region of Sweden (313,235 bacterial cultures from 128,982 individuals) from January 1, 2004, to December 31, 2006. Among all samples sent for culture, a pharyngeal sample was associated with a higher risk for PsA onset within the next 50 days compared with urine (hazard ratio [HR] 8.78; 95% CI 3.23-23.91), nasopharyngeal (HR 8.26; 95% CI 2.23-30.63), or blood (HR 25.22; 95% CI 3.12-204.13) samples. Streptococcal infections in the pharynx or at any other site were not associated with an increased risk for PsA. Similar associations were found for psoriasis, but not for rheumatoid arthritis. These results indicate that having sent a pharyngeal sample for culture was associated with an increased risk for psoriatic disease onset, suggesting that the site of infection—rather than the pathogen—is associated with the increased risk. These intriguing results support the need to further study the role of site and type of infection and antibiotic use on psoriatic disease onset.

With regard to other risk factors for PsA, a meta-analysis by Pouw and colleagues looked at 29 studies including adult patients with psoriasis with or without concurrent PsA or adult patients with psoriasis who developed PsA. The analysis showed that the body surface area affected by psoriasis was significantly higher in patients with psoriasis and concurrent PsA vs patients with only psoriasis (mean difference 5.31; 95% CI 1.78-8.83). Severe psoriasis was a significant predictor of concurrent PsA (odds ratio 3.34; P < .001). Thus, optimum care of patients with PsA requires excellent collaboration between rheumatologists and dermatologists.

Factors such as sex and body mass index (BMI) are likely to have a role in PsA treatment response but have not been extensively evaluated. To address this issue, Mease and colleagues conducted a post hoc analysis of the phase 3 SEAM-PsA trial including 851 patients who were methotrexate (MTX)/biologics naive and had early PsA. They were randomly assigned to receive MTX + placebo, etanercept + placebo, or MTX + etanercept. The study demonstrated that at week 24 a higher proportion of men vs women receiving MTX + etanercept achieved the American College of Rheumatology 20% criteria (ACR20) (71.5% vs 58.3%; P = .0194) and minimal disease activity (MDA) (45.8% vs 25.2%; P = .0003). A higher proportion of patients with a BMI ≤ 30 vs > 30 in all treatment groups achieved MDA (all P < .05), and those in the MTX + etanercept group achieved ACR20 (P = .0241). Thus, men (vs women) and those with lower BMI experience significantly better outcomes with treatment. When counseling patients about response to treatment, sex and BMI need to be taken into consideration. Moreover, further research is required to confirm and identify the reasons underlying these findings and to optimize treatment outcomes.

Another post hoc study explored the association between baseline disease activity and achieving the treatment target in PsA. Mease and colleagues analysed data from the phase 3 PALACE 4 study including 175 patients who were disease-modifying antirheumatic drug (DMARD)–naive and had active PsA. They received 30 mg apremilast twice daily. The study found that at week 52, remission or low disease activity according to the Clinical Disease Activity Index for Psoriatic Arthritis was achieved in 61.7% of patients with moderate disease activity vs 28.2% of these with high disease activity at baseline. Thus, DMARD-naive patients with moderate (vs high) disease activity at baseline are more likely to achieve low disease activity after apremilast therapy.

Factors such as sex and body mass index (BMI) are likely to have a role in PsA treatment response but have not been extensively evaluated. To address this issue, Mease and colleagues conducted a post hoc analysis of the phase 3 SEAM-PsA trial including 851 patients who were methotrexate (MTX)/biologics naive and had early PsA. They were randomly assigned to receive MTX + placebo, etanercept + placebo, or MTX + etanercept. The study demonstrated that at week 24 a higher proportion of men vs women receiving MTX + etanercept achieved the American College of Rheumatology 20% criteria (ACR20) (71.5% vs 58.3%; P = .0194) and minimal disease activity (MDA) (45.8% vs 25.2%; P = .0003). A higher proportion of patients with a BMI ≤ 30 vs > 30 in all treatment groups achieved MDA (all P < .05), and those in the MTX + etanercept group achieved ACR20 (P = .0241). Thus, men (vs women) and those with lower BMI experience significantly better outcomes with treatment. When counseling patients about response to treatment, sex and BMI need to be taken into consideration. Moreover, further research is required to confirm and identify the reasons underlying these findings and to optimize treatment outcomes.

Another post hoc study explored the association between baseline disease activity and achieving the treatment target in PsA. Mease and colleagues analysed data from the phase 3 PALACE 4 study including 175 patients who were disease-modifying antirheumatic drug (DMARD)–naive and had active PsA. They received 30 mg apremilast twice daily. The study found that at week 52, remission or low disease activity according to the Clinical Disease Activity Index for Psoriatic Arthritis was achieved in 61.7% of patients with moderate disease activity vs 28.2% of these with high disease activity at baseline. Thus, DMARD-naive patients with moderate (vs high) disease activity at baseline are more likely to achieve low disease activity after apremilast therapy.

Infections have long been identified as possible triggers for psoriasis and psoriatic arthritis (PsA) onset. Thrastardottir and colleagues evaluated the association between sites where the culture sample was obtained, the culture result, and pathogens and incident PsA and psoriasis. They obtained data on all samples sent for bacterial culture in the Stockholm region of Sweden (313,235 bacterial cultures from 128,982 individuals) from January 1, 2004, to December 31, 2006. Among all samples sent for culture, a pharyngeal sample was associated with a higher risk for PsA onset within the next 50 days compared with urine (hazard ratio [HR] 8.78; 95% CI 3.23-23.91), nasopharyngeal (HR 8.26; 95% CI 2.23-30.63), or blood (HR 25.22; 95% CI 3.12-204.13) samples. Streptococcal infections in the pharynx or at any other site were not associated with an increased risk for PsA. Similar associations were found for psoriasis, but not for rheumatoid arthritis. These results indicate that having sent a pharyngeal sample for culture was associated with an increased risk for psoriatic disease onset, suggesting that the site of infection—rather than the pathogen—is associated with the increased risk. These intriguing results support the need to further study the role of site and type of infection and antibiotic use on psoriatic disease onset.

With regard to other risk factors for PsA, a meta-analysis by Pouw and colleagues looked at 29 studies including adult patients with psoriasis with or without concurrent PsA or adult patients with psoriasis who developed PsA. The analysis showed that the body surface area affected by psoriasis was significantly higher in patients with psoriasis and concurrent PsA vs patients with only psoriasis (mean difference 5.31; 95% CI 1.78-8.83). Severe psoriasis was a significant predictor of concurrent PsA (odds ratio 3.34; P < .001). Thus, optimum care of patients with PsA requires excellent collaboration between rheumatologists and dermatologists.
