CGRP monoclonal antibodies and gepants: Safe and well-tolerated options for migraine prevention
Key clinical point: Network meta-analysis confirms the overall safety of anti-calcitonin gene-related peptide (CGRP) monoclonal antibodies and gepants for migraine prevention, with rare instances of treatment discontinuation.
Major finding: The risk for serious adverse events was not significantly different with active treatments and placebo, with 30 mg eptinezumab being the only treatment significantly associated with higher odds of adverse events leading to treatment discontinuation (odds ratio [OR] 2.62; 95% CI 1.03-6.66). Compared with placebo, the risk for treatment-emergent adverse events was not significantly different with 30 mg and 100 mg eptinezumab and was the highest with 240 mg galcanezumab (OR 1.63; 95% CI 1.33-2.00) and 120 mg galcanezumab (OR 1.40; 95% CI 1.16-1.70), with the most frequent being injection site erythema, induration, and pruritus.
Study details: The data come from a network meta-analysis of 19 phase 3 randomized controlled trials including 14,584 patients with migraine.
Disclosures: This study did not report the source of funding. The authors declared no conflicts of interest.

Intranasal zavegepant shows potential as an effective treatment option for acute migraine
Key clinical point: Zavegepant nasal spray was effective in the acute treatment of migraine, with favorable tolerability and safety profiles.
Major finding: At 2 hours post-dose, higher proportions of patients treated with zavegepant vs placebo were free from pain (risk difference 8.8 percentage points; P < .0001) and from their most bothersome symptom (risk difference 8.7 percentage points; P = .0012). Dysgeusia (21% vs 5%), nasal discomfort (4% vs 1%), and nausea (3% vs 1%) were the most common adverse events in the zavegepant vs placebo group.
Study details: Findings are from a phase 3 trial including 1405 patients with ≥1-year history of migraine with or without aura who were randomly assigned to receive zavegepant 10 mg nasal spray (n = 703) or matching placebo (n = 702).
Disclosures: This study was funded by Biohaven Pharmaceuticals. Some authors declared being employees of and holding stocks or stock options in Biohaven Pharmaceuticals. Some others declared ties with various sources, including Biohaven Pharmaceuticals.

Early treatment considerations in RA, April 2023
In evaluating the importance of early aggressive treatment of rheumatoid arthritis (RA), we often look at prognostic factors for severe disease, such as seropositivity, elevated inflammatory markers, and erosions. Eberhard and colleagues looked at the relationship between damage as seen on radiography (including erosions and joint space narrowing) and pain and disability in early RA using an inception cohort with <12 months of symptoms. Over 200 patients in Sweden were followed for 5 years with clinical, laboratory, and radiographic evaluations. Of interest, pain was associated with female sex, tender joint count, and inflammatory markers at various time points but not with radiographic damage. This may reflect that pain is related to current inflammation rather than past joint damage or that pain is related to other factors, such as central sensitization. Radiographic damage was, however, associated with disability and thus remains an important target and outcome measure for assessing treatment effectiveness.
Leon and colleagues also looked at early RA but instead, at the category of difficult-to-treat RA (D2T RA), meaning persistent RA symptoms after a trial of at least two biologic or targeted synthetic disease-modifying antirheumatic drugs. In order to gain better insight in preventing D2T RA, the authors examined its association with potentially modifiable risk factors early in the course of disease. Of the over 600 patients followed in this inception cohort, only about 6% were classified as having D2T RA. The study found that patients who had D2T RA tended to be younger, with a higher tender joint count, higher pain scores, and a higher initial level of disability. The Disease Activity Score (DAS28) itself was higher in patients with D2T RA, but the difference did not reach statistical significance. The small number of patients (35) in the D2T RA group may have affected the findings as well as their wider applicability. However, it is interesting to consider whether the associations may also reflect the impact of noninflammatory factors, as in the previous study, on the classification of D2T RA.
Park and colleagues evaluated the difference in clinical outcomes in postmenopausal patients with RA who underwent menopause at younger than 45 years or 45 years or older. Among over 2800 patients in Korea, those who underwent early menopause were more likely to be seronegative and have high disease activity and worse patient-reported outcome scores in fatigue, sleep, and health-related quality of life despite comparable treatments and prevalence of erosions. The authors suggest this may be related to lower cumulative estrogen exposure; whether this correlates to inflammatory cytokine signatures is not yet known. However, as with the prior studies, central sensitization and noninflammatory pain may also contribute and should be considered in interpreting response to therapy.
Finally, addressing the potential risk for cancer in patients with RA before or during treatment with immunosuppressive medications, Miyata and colleagues reported a study that screened nearly 2200 patients who underwent CT (from neck to pelvis) and compared them with those who underwent routine screening with physical exam plus radiography. The study found that CT screening enhanced cancer detection, with a large number of cancers detected at an earlier stage with CT screening compared with routine screening. The overall number of cancers detected was low (33), and thus routine screening with neck-to-pelvis CT for all patients with RA may not be a cost-effective practice. However, it bears further examination for potentially higher-risk populations or specific cancers.

Commentary: Updates on the Treatment of Mantle Cell Lymphoma, April 2023
Mantle cell lymphoma (MCL) is an uncommon subtype of non-Hodgkin lymphoma (NHL) that is clinically heterogeneous, ranging from indolent to aggressive in nature. As with other subtypes of NHL, the treatment landscape is rapidly evolving.
Chemoimmunotherapy remains the standard first-line therapy for younger, fit patients. Although multiple induction regimens are used in this setting, it is typical to use a cytarabine-containing approach. Recently, the long-term analysis of the MCL Younger trial continued to demonstrate improved outcomes with this strategy.1 This phase 3 study included 497 patients aged ≥ 18 to < 66 years with previously untreated MCL who were randomly assigned to R-CHOP (cyclophosphamide, doxorubicin, prednisone, rituximab, and vincristine; n = 249) or R-DHAP (rituximab, dexamethasone, cytarabine, cisplatin; n = 248). After a median follow-up of 10.6 years, the R-DHAP vs R-CHOP arm continued to have a significantly longer time to treatment failure (hazard ratio [HR] 0.59; P = .038) and overall survival (Mantle Cell Lymphoma International Prognostic Index + Ki-67–adjusted HR 0.60; P = .0066).
Following chemoimmunotherapy, treatment for this patient population typically consists of consolidation with autologous stem cell transplantation (ASCT) and maintenance rituximab.2 Recently, the role of ASCT has been called into question.3 Preliminary data from the phase 3 TRIANGLE study demonstrated improvement in outcomes when the Bruton tyrosine kinase (BTK) inhibitor ibrutinib was added to chemoimmunotherapy, regardless of whether patients received ASCT.4 Additional studies evaluating the role of transplantation, particularly among patients who are minimal residual disease negative after chemoimmunotherapy, are ongoing (NCT03267433).
Options continue to expand in the relapsed/refractory setting. The chimeric antigen receptor (CAR) T-cell therapy, brexucabtagene autoleucel (brexu-cel), was approved by the US Food and Drug Administration for relapsed/refractory MCL on the basis of the results of the ZUMA-2 study.5 Recently, a multicenter, retrospective study demonstrated promising efficacy in the real world as well (Wang et al). This study was performed across 16 medical centers and included 189 patients with relapsed/refractory MCL who underwent leukapheresis for commercial manufacturing of brexu-cel, of which 168 received brexu-cel infusion. Of all patients receiving leukapheresis, 149 (79%) would not have met the eligibility criteria for ZUMA-2. At a median follow-up of 14.3 months after infusion, the best overall and complete response rates were 90% and 82%, respectively. The 6- and 12-month progression-free survival (PFS) rates were 69% (95% CI 61%-75%) and 59% (95% CI 51%-66%), respectively. This approach, however, was associated with significant toxicity, with a nonrelapse mortality rate of 9.1% at 1 year, primarily because of infections. The grade ≥ 3 cytokine release syndrome and neurotoxicity rates were 8% and 32%, respectively. Despite risks, this study confirms the role of CAR T-cell therapy for patients with relapsed/refractory MCL.
Other options in the relapsed setting include BTK and anti-apoptotic protein B-cell lymphoma (BCL-2) inhibitors. Although venetoclax, a BCL-2 inhibitor, has demonstrated activity in MCL in early-phase clinical trials, the role of this drug in clinical practice remains unclear.6,7 A recent multicenter, retrospective study evaluated the use of venetoclax in 81 adult patients with relapsed/refractory MCL, most of whom were heavily pretreated (median of three prior treatments) and had high-risk features, including high Ki-67 and TP53 alterations, who received venetoclax without (n = 50) or with (n = 31) other agents (Sawalha et al). In this study, venetoclax resulted in a good overall response rate (ORR) but short PFS. At a median follow-up of 16.4 months, patients had a median PFS and overall survival of 3.7 months (95% CI 2.3-5.6) and 12.5 months (95% CI 6.2-28.2), respectively, and an ORR of 40%. Studies of venetoclax in earlier lines of therapy and in combination with other agents are ongoing. There may also be a role for this treatment as a bridge to more definitive therapies, including CAR T-cell therapy or allogeneic stem cell transplantation. Other studies that are evaluating the role of bispecific antibodies and antibody drug conjugates are also underway, suggesting the potential for additional options in this patient population.

Mantle cell lymphoma (MCL) is an uncommon subtype of non-Hodgkin lymphoma (NHL) that is clinically heterogeneous, ranging from indolent to aggressive in nature. As with other subtypes of NHL, the treatment landscape is rapidly evolving.
Chemoimmunotherapy remains the standard first-line therapy for younger, fit patients. Although multiple induction regimens are used in this setting, it is typical to use a cytarabine-containing approach. Recently, the long-term analysis of the MCL Younger trial continued to demonstrate improved outcomes with this strategy.1 This phase 3 study included 497 patients aged ≥ 18 to < 66 years with previously untreated MCL who were randomly assigned to R-CHOP (cyclophosphamide, doxorubicin, prednisone, rituximab, and vincristine; n = 249) or R-DHAP (rituximab, dexamethasone, cytarabine, cisplatin; n = 248). After a median follow-up of 10.6 years, the R-DHAP vs R-CHOP arm continued to have a significantly longer time to treatment failure (hazard ratio [HR] 0.59; P = .038) and overall survival (Mantle Cell Lymphoma International Prognostic Index + Ki-67–adjusted HR 0.60; P = .0066).
Following chemoimmunotherapy, treatment for this patient population typically consists of consolidation with autologous stem cell transplantation (ASCT) and maintenance rituximab.2 Recently, the role of ASCT has been called into question.3 Preliminary data from the phase 3 TRIANGLE study demonstrated improvement in outcomes when the Bruton tyrosine kinase (BTK) inhibitor ibrutinib was added to chemoimmunotherapy, regardless of whether patients received ASCT.4 Additional studies evaluating the role of transplantation, particularly among patients who are minimal residual disease negative after chemoimmunotherapy, are ongoing (NCT03267433).
Options continue to expand in the relapsed/refractory setting. The chimeric antigen receptor (CAR) T-cell therapy, brexucabtagene autoleucel (brexu-cel), was approved by the US Food and Drug Administration for relapsed/refractory MCL on the basis of the results of the ZUMA-2 study.5 Recently, a multicenter, retrospective study demonstrated promising efficacy in the real world as well (Wang et al). This study was performed across 16 medical centers and included 189 patients with relapsed/refractory MCL who underwent leukapheresis for commercial manufacturing of brexu-cel, of which 168 received brexu-cel infusion. Of all patients receiving leukapheresis, 149 (79%) would not have met the eligibility criteria for ZUMA-2. At a median follow-up of 14.3 months after infusion, the best overall and complete response rates were 90% and 82%, respectively. The 6- and 12-month progression-free survival (PFS) rates were 69% (95% CI 61%-75%) and 59% (95% CI 51%-66%), respectively. This approach, however, was associated with significant toxicity, with a nonrelapse mortality rate of 9.1% at 1 year, primarily because of infections. The grade ≥ 3 cytokine release syndrome and neurotoxicity rates were 8% and 32%, respectively. Despite risks, this study confirms the role of CAR T-cell therapy for patients with relapsed/refractory MCL.
Other options in the relapsed setting include BTK and anti-apoptotic protein B-cell lymphoma (BCL-2) inhibitors. Although venetoclax, a BCL-2 inhibitor, has demonstrated activity in MCL in early-phase clinical trials, the role of this drug in clinical practice remains unclear.6,7 A recent multicenter, retrospective study evaluated the use of venetoclax in 81 adult patients with relapsed/refractory MCL, most of whom were heavily pretreated (median of three prior treatments) and had high-risk features, including high Ki-67 and TP53 alterations, who received venetoclax without (n = 50) or with (n = 31) other agents (Sawalha et al). In this study, venetoclax resulted in a good overall response rate (ORR) but short PFS. At a median follow-up of 16.4 months, patients had a median PFS and overall survival of 3.7 months (95% CI 2.3-5.6) and 12.5 months (95% CI 6.2-28.2), respectively, and an ORR of 40%. Studies of venetoclax in earlier lines of therapy and in combination with other agents are ongoing. There may also be a role for this treatment as a bridge to more definitive therapies, including CAR T-cell therapy or allogeneic stem cell transplantation. Other studies that are evaluating the role of bispecific antibodies and antibody drug conjugates are also underway, suggesting the potential for additional options in this patient population.

Commentary: Alisertib, trastuzumab, and treatment timing, April 2023
HER2-positive (HER2+) BC was associated with poor outcomes compared with other BC subtypes. However, the introduction of trastuzumab has drastically changed the treatment paradigm for these patients afflicted with HER2+ BC. The pivotal trials with trastuzumab included only a few patients with lower-risk HER2+ tumors; therefore, it was not clear whether these lower-risk patients can benefit from a de-escalated adjuvant regimen. The phase 2 APT trial prospectively investigated the safety and efficacy of 12 weeks of paclitaxel with trastuzumab, followed by 9 months of trastuzumab monotherapy, in patients with small (≤ 3 cm), node-negative, HER2+ BC. After a median follow-up of 10.8 years, the 10-year invasive disease-free survival was 91.3%, the recurrence-free interval was 96.3%, the overall survival rate was 94.3%, and the BC-specific survival rate was 98.8%.
The researchers also conducted an exploratory analysis in 284 patients using the HER2DX genomic test. This is a single 27-gene expression and clinical feature-based classifier developed for early-stage, HER2+ BC. The tool identified a subset of patients with a high HER2DX score (HERDX score ≥ 32) who might harbor an increased risk for long-term recurrence.
These excellent long-term outcomes from the APT trial support the use of the currently endorsed adjuvant regimen of paclitaxel and trastuzumab in patients with stage I HER2+ BC. Furthermore, the HER2DX risk score, if validated, may provide a promising genomic tool to identify a subset of these patients who are at increased risk for recurrence and therefore may benefit from additional therapy.
Prior studies have noted worse survival outcomes with longer times from BC diagnosis to surgical treatment; however, the specific time interval that is acceptable to wait between diagnosis and surgery is still unclear. A case series study by Weiner and colleagues looked at the association between time from BC diagnosis to primary breast surgery and overall survival. The study looked at 373,334 female patients from the National Cancer Database with stage I-III BC who underwent primary breast surgery. Results showed worse overall survival outcomes when time to surgery was 9 or more weeks compared with surgery between 0 and 4 weeks (hazard ratio 1.15; P < .001). Factors associated with longer times to surgery included younger age, uninsured or Medicaid status, and lower neighborhood household income. On the basis of these findings, surgery before 8 weeks from BC diagnosis appears to be an acceptable time frame to avoid unfavorable survival outcomes and allow for appropriate multidisciplinary care. Furthermore, it is critical to identify potential barriers in a timely manner to prevent prolonged delays in care.
In hormone receptor-positive (HR+) BC, adjuvant endocrine therapy (ET) is usually delayed until after adjuvant radiotherapy, although, the optimal sequence of both therapies is still unknown. The aim of the study by Sutton and colleagues was to assess the association between time from surgery to ET initiation and cancer outcomes in high-risk HR+ patients, particularly those with residual disease after neoadjuvant chemotherapy. The study analysed 179 patients with HR+ BC from a multi-institutional database who received adjuvant radiotherapy, of which 68 patients received adjuvant ET before or during radiotherapy and 111 patients received ET after cessation of radiotherapy. Results showed that an interval of >14 weeks between surgery and the receipt of ET was independently associated with worse recurrence-free survival compared with an interval of 14 or less weeks (hazard ratio 3.20; P = .02). Of interest, the study also showed that patients receiving ET before or during radiation were more likely to experience skin and soft tissue late radiation morbidity, and this was nonsignificantly associated with worse radiation-associated complication-free survival (hazard ratio 1.87; P = .06). Although prior studies have reported that the interval from surgery to ET does not affect cancer outcomes, this was not studied in a high-risk cohort who have received neoadjuvant chemotherapy. Further studies in larger prospective cohorts are needed to validate these findings. At this time, the risks and benefits of concurrent ET with radiation need to be assessed prior to making any treatment recommendations.

Commentary: Chemotherapies and gynecologic surgeries relative to breast cancer, April 2023
However, a combined analysis of two other trials (PlanB and SUCCESS C) did not show a benefit with the addition of anthracycline for most patients with human epidermal growth factor receptor 2 (HER2)–negative early breast cancer.2 Roy and colleagues performed a retrospective study using the Surveillance, Epidemiology, and End Results (SEER)-Medicare database, including 1106 women ≥ 66 years of age with node-positive TNBC, of whom 69.3% received adjuvant chemotherapy (N = 767). The use of chemotherapy led to a statistically significant improvement in survival outcomes (3-year cancer-specific survival [CSS] 81.8% vs 71.4%; overall survival 70.7% vs 51.3%). Although the anthracycline/taxane–based therapy did not improve CSS in the overall population vs taxane-based (hazard ratio [HR] 0.94; P = .79), among patients aged ≥ 76 years with four or more positive nodes, there was improvement in CSS with anthracycline/taxane therapy (HR 0.09; P = .02). These data further support the benefits of adjuvant chemotherapy in older patients when indicated; stimulate consideration of nonanthracycline combinations, particularly now with the use of immunotherapy for early TNBC; and highlight the need for inclusion of older individuals in clinical trials.
Treatment strategies to improve efficacy and minimize toxicity are highly desired for patients with early breast cancer (EBC). As an example, for small, node-negative, HER2-positive tumors, adjuvant systemic therapy with 12 weeks of paclitaxel/trastuzumab followed by continuation of trastuzumab to complete 1 full year has demonstrated excellent survival outcomes at over 10 years of follow-up.3 In the WSG-ADAPT-TP phase 2 trial, 375 patients with hormone receptor–positive , HER2-positive EBC were randomized to receive neoadjuvant T-DM1 (trastuzumab emtansine) with or without endocrine therapy or trastuzumab plus endocrine therapy. Similar 5-year invasive disease-free and overall survival rates were seen between the three arms. Patients who achieved a pathologic complete response (pCR) vs non-pCR had improved 5-year invasive disease-free survival (iDFS) rates (92.7% vs 82.7%; unadjusted HR 0.40). Furthermore, among the 117 patients who achieved pCR, the omission of adjuvant chemotherapy did not compromise survival outcomes (5-year iDFS 93% vs 92.1% for those who had vs those who did not have chemotherapy, respectively; unadjusted HR 1.15) (Harbeck et al). De-escalation approaches should ideally focus on the identification of biomarkers of response and resistance, as well as tools that can help predict patient outcomes and allow modification of therapy in real time. An example of this latter concept is the use of 18F-FDG-PET to identify patients with HER2-positive EBC who were likely to benefit from a chemotherapy-free dual HER2 blockade (trastuzumab/pertuzumab) treatment approach.4
Gynecologic surgery has been shown to reduce the risk for breast cancer,5 although the specific type of surgery and the impact of hormone replacement therapy add complexity to understanding the risks and outcomes for women. A prospective cohort, the Sister Study, included 50,701 women without a prior diagnosis of breast cancer but with a biological sister who had breast cancer; of these, 13.8% reported having hysterectomy only and 18.1% reported having bilateral oophorectomy with or without hysterectomy. Bilateral oophorectomy was inversely associated with breast cancer incidence (HR 0.91; 95% CI 0.83-1.00), with comparable results for women receiving estrogen only or combination estrogen plus progestin hormone replacement therapy. Contrary to these findings, having a hysterectomy only showed a positive association with breast cancer incidence (HR 1.12; 95% CI 1.02-1.23), with the strongest association among women who used combination estrogen and progestin therapy (HR 1.25; 95% CI 1.01-1.55) (Lovett et al). The impact of other gynecologic surgeries (such as salpingectomy)6 and the timing of the initiation of hormone replacement therapy, as well as the duration, should be investigated in future research.

However, a combined analysis of two other trials (PlanB and SUCCESS C) did not show a benefit with the addition of anthracycline for most patients with human epidermal growth factor receptor 2 (HER2)–negative early breast cancer.2 Roy and colleagues performed a retrospective study using the Surveillance, Epidemiology, and End Results (SEER)-Medicare database, including 1106 women ≥ 66 years of age with node-positive TNBC, of whom 69.3% received adjuvant chemotherapy (N = 767). The use of chemotherapy led to a statistically significant improvement in survival outcomes (3-year cancer-specific survival [CSS] 81.8% vs 71.4%; overall survival 70.7% vs 51.3%). Although the anthracycline/taxane–based therapy did not improve CSS in the overall population vs taxane-based (hazard ratio [HR] 0.94; P = .79), among patients aged ≥ 76 years with four or more positive nodes, there was improvement in CSS with anthracycline/taxane therapy (HR 0.09; P = .02). These data further support the benefits of adjuvant chemotherapy in older patients when indicated; stimulate consideration of nonanthracycline combinations, particularly now with the use of immunotherapy for early TNBC; and highlight the need for inclusion of older individuals in clinical trials.
Treatment strategies to improve efficacy and minimize toxicity are highly desired for patients with early breast cancer (EBC). As an example, for small, node-negative, HER2-positive tumors, adjuvant systemic therapy with 12 weeks of paclitaxel/trastuzumab followed by continuation of trastuzumab to complete 1 full year has demonstrated excellent survival outcomes at over 10 years of follow-up.3 In the WSG-ADAPT-TP phase 2 trial, 375 patients with hormone receptor–positive , HER2-positive EBC were randomized to receive neoadjuvant T-DM1 (trastuzumab emtansine) with or without endocrine therapy or trastuzumab plus endocrine therapy. Similar 5-year invasive disease-free and overall survival rates were seen between the three arms. Patients who achieved a pathologic complete response (pCR) vs non-pCR had improved 5-year invasive disease-free survival (iDFS) rates (92.7% vs 82.7%; unadjusted HR 0.40). Furthermore, among the 117 patients who achieved pCR, the omission of adjuvant chemotherapy did not compromise survival outcomes (5-year iDFS 93% vs 92.1% for those who had vs those who did not have chemotherapy, respectively; unadjusted HR 1.15) (Harbeck et al). De-escalation approaches should ideally focus on the identification of biomarkers of response and resistance, as well as tools that can help predict patient outcomes and allow modification of therapy in real time. An example of this latter concept is the use of 18F-FDG-PET to identify patients with HER2-positive EBC who were likely to benefit from a chemotherapy-free dual HER2 blockade (trastuzumab/pertuzumab) treatment approach.4
Gynecologic surgery has been shown to reduce the risk for breast cancer,5 although the specific type of surgery and the impact of hormone replacement therapy add complexity to understanding the risks and outcomes for women. A prospective cohort, the Sister Study, included 50,701 women without a prior diagnosis of breast cancer but with a biological sister who had breast cancer; of these, 13.8% reported having hysterectomy only and 18.1% reported having bilateral oophorectomy with or without hysterectomy. Bilateral oophorectomy was inversely associated with breast cancer incidence (HR 0.91; 95% CI 0.83-1.00), with comparable results for women receiving estrogen only or combination estrogen plus progestin hormone replacement therapy. Contrary to these findings, having a hysterectomy only showed a positive association with breast cancer incidence (HR 1.12; 95% CI 1.02-1.23), with the strongest association among women who used combination estrogen and progestin therapy (HR 1.25; 95% CI 1.01-1.55) (Lovett et al). The impact of other gynecologic surgeries (such as salpingectomy)6 and the timing of the initiation of hormone replacement therapy, as well as the duration, should be investigated in future research.

Commentary: IL-31 inhibitor, e-cigarettes, and upadacitinib in AD, April 2023
Good news! There's not a lot to say about this. Dupilumab is so easy. No blood work, no immunosuppression. Dupilumab is highly effective and very safe. It's safe enough for children as young as 6 months! It's so effective that if it is not working, I question my diagnosis (Could it be contact dermatitis or mycosis fungoides instead?) and whether the patient is taking the medication properly.
Boesjes and colleagues describe in Acta Dermato-Venereologica the Dutch experience with upadacitinib in patients who have not been successfully treated with dupilumab or baricitinib. Presumably, such patients, because treatment with dupilumab or baricitinib or both was unsuccessful, have very resistant atopic dermatitis (either due to strong genetic propensity or perhaps because they don't take their medications). Despite having such refractory disease, most patients did well on the treatment with rapid disease improvement. Upadacitinib didn't work for everyone, though. About 30% of the patients discontinued upadacitinib treatment due to ineffectiveness, adverse events, or both (8.5%, 14.9%, and 6.4%, respectively).
How much of that ineffectiveness was due to poor adherence to taking the treatment was not assessed. Upadacitinib is extraordinarily effective for atopic dermatitis. I didn't think I would ever see a drug more effective than dupilumab for atopic dermatitis, but a low dose of upadacitinib (15 mg/day) seems about twice as effective as dupilumab for complete clearing of atopic dermatitis. The higher dose of 30 mg may be 3.5 times as effective as dupiliumab at getting atopic dermatitis completely clear.1
I dislike the word significant. Significant is ambiguous. It could mean that an observed association would not be likely to occur by chance, or it could mean that an observed association is clinically meaningful. Smith and colleagues in "Association between electronic cigarette use and atopic dermatitis among United States adults" reported finding a "significant" association between e-cigarette use and atopic dermatitis. A total of 23% of 2119 e-cigarette users had atopic dermatitis vs 17.1% of 26,444 nonusers. Clearly, the observed association was statistically significant (the 6% difference was not likely to occur due to chance alone). Is the finding clinically meaningful? I don't think it would affect our practice in any way.
The authors made the point that the study doesn't tell us whether e-cigarette use causes atopic dermatitis or if atopic dermatitis causes people to smoke. I wonder if just being younger (or some other factor) might make people more likely to use e-cigarettes and more likely to have atopic dermatitis (assuming atopic dermatitis gradually subsides over time, a dogma that may not be true).
Kabashima and colleagues report on the efficacy of the interleukin (IL)–31 antagonist nemolizumab. IL-31 mediates itch and having a new drug to block IL-31 may be a great treatment for our itchy patients. In this study, patients who had greater itch reduction had greater improvement in eczema and in quality of life. I'm quite sure that reducing itch improves patients' quality of life. But when it comes to the itch and the inflammation, I'm not sure which comes first. Does controlling the itch make the inflammation better? Maybe. Does controlling inflammation make itch better? Certainly.
For atopic patients with inflammation, controlling that inflammation seems to me to be the best approach, and we don't need more new treatments to accomplish that. For those patients who have a lot of itch and little inflammation, an IL-31 antagonist may be a revolutionary addition to our treatment options.

Real-world study compares discontinuation rates of tofacitinib and TNFi in RA
Key clinical point: The overall treatment discontinuation rate was similar among patients with rheumatoid arthritis (RA) who initiated tofacitinib vs tumor necrosis factor inhibitors (TNFi), but discontinuation because of adverse events was higher among those initiating tofacitinib.
Major finding: Patients initiating TNFi vs tofacitinib were less likely to discontinue treatment due to adverse events (hazard ratio 0.48; log-rank P = .003) but were equally likely to discontinue treatment due to any reason (log-rank P = .67) or inefficacy (log-rank P = .70). Concomitant methotrexate had no effect on treatment discontinuation.
Study details: This population-based retrospective cohort study pooled data from two registries and evaluated 1318 patients with RA who initiated tofacitinib (n = 493) or TNFi (n = 825), of which 746 patients received concomitant methotrexate.
Disclosures: This study did not receive any specific funding. Two authors declared receiving research funding, speaker honoraria or serving as consultants or advisory board members for various sources. Four authors declared being employees, faculty members, or owners of different organizations.

Systemic immune-inflammation index: Novel biomarker to predict RA risk in adults
Key clinical point: A high level of systemic immune-inflammation index (SII) is positively correlated with an increased risk for rheumatoid arthritis (RA).
Major finding: Higher SII score was significantly associated with an increased risk of developing RA, with every unit increase in SII score increasing the risk for RA by approximately 17% (adjusted odds ratio,1.167; P = .020). The risk for RA rapidly increased when SII exceeded the cutoff value of 578.25.
Study details: This study analyzed the data of 37,604 individuals from the US National Health and Nutrition Examination Survey, a population-based cross-sectional survey, of which 2642 had RA.
Disclosures: This study did not receive any funding support. The authors declared no conflicts of interest.

Joint damage associated with increased disability but not pain in early RA
Key clinical point: In early rheumatoid arthritis (RA), joint damage was significantly associated with disability but not with patient-reported pain at inclusion and during 5-year follow-up. Cartilage damage seemed to affect function in the longer run.
Major finding: The erosion score was significantly associated with Health Assessment Questionnaire score (HAQ) at inclusion (regression coefficient [β] 0.032; P = .02) and after 5 years (β 0.009; P = .02) in a cross-sectional analysis, whereas joint space narrowing score (JSNS) was associated with HAQ only at 5 years (β 0.010; 95% CI 0.004-0.016) in the longitudinal analysis. The erosion score and JSNS had no association with Visual Analogue Scale of Pain at all time points.
Study details: The data come from a longitudinal cohort study including 233 patients with early RA who had symptoms for ≤12 months and were followed for 5 years.
Disclosures: This study was supported by The Swedish Research Council and other sources. The authors declared no conflicts of interest.
