Abstract Introduction: CD19-directed CAR T-cell (CAR-T) therapy has substantially improved clinical outcomes for adults with relapsed or refractory (R/R) B-cell acute lymphoblastic leukemia (B-ALL). However, notable toxicities are associated with CAR-T, including cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS). Variable practice patterns have emerged regarding the use of CRS/ICANS prophylaxis (ppx) via corticosteroids and/or other pharmacologic agents, but the utility of these approaches on reducing CRS or ICANS following CAR-T in B-ALL remains unknown. Thus, we utilized the Real-World Outcomes Collaborative for CAR T in ALL (ROCCA) database to evaluate associations between ppx and the development and severity of CRS or ICANS following brexucabtagene autoleucel (brexu-cel) for B-ALL. Methods: Adult patients (pts) who received standard-of-care brexu-cel for relapsed/refractory B-ALL across 40+ US centers were included. Primary endpoints were the incidence of CRS and ICANS within 28 days of CAR-T infusion. Secondary endpoints included timing of CRS and ICANS onset, progression-free survival (PFS) and overall survival (OS). Univariable and multivariable logistic regression evaluated associations between ppx and incidence of CRS/ICANS; KM and log-rank methods were used for survival analyses. Results: A total of 378 pts were included: 53 pts (14.0%) received CRS/ICANS ppx and 325 (86.0%) received no ppx. Ppx agents included steroids only (26.4%), steroid and anakinra (52.8%), anakinra only (15.1%), and steroid and tocilizumab (5.7%). Pts in the ppx group had a higher proportion of Hispanic pts (64% vs 34%), Ph-like (36% vs 19%) and a lower proportion had 0-5% bone marrow blasts at apheresis (38% vs 53%). The ppx and no ppx groups were similar in age, prior therapies, CAR-T indication, and marrow blasts >50%. Cumulative incidence of any grade (gr) CRS was 94% with ppx and 86% with no ppx (p=0.025), of any gr ICANS was 53% with ppx and 51% with no ppx (0= 0.85). Cumulative incidence of gr 3-4 CRS was 9% in the ppx group and 10% in the no ppx group (p=1.00), of gr 3-4 ICANS was 26% in the ppx group and 29% in the no ppx group (p=0.71). Median time to onset for any gr CRS or any gr ICANS was identical in the ppx and no ppx cohorts (CRS: 5 days, range ppx 1-9 days, no ppx 0-14 days; ICANS: 7 days, ppx 1-20 days, no ppx 0-16 days). Univariate logistic regression analyses showed no significant association between ppx and the incidence of gr 2-4 CRS (OR 1.34, 95% CI: 0.75-2.40, p=0.326) or gr 3-4 ICANS (OR 0.88, 95% CI: 0.46-1.70, p=0.708). Multivariate analysis adjusting for ethnicity, leukemia genetic sub-type, and pre-apheresis disease burden similarly found no significant associations between ppx and gr 2-4 CRS (adjusted OR 1.06, 95% CI: 0.55-2.01, p=0.870) or gr 3-4 ICANS (OR 1.23, 95% CI: 0.59-2.55, p=0.584). When comparing steroid-only ppx (N=14) to steroid combinations or other drug ppx (N=39), there was no significant differences in gr 2-4 CRS (57% vs 44%, p=0.345) or gr 3-4 ICANS (43% vs 21%, p=0.115). Comparing cumulative incidence of dexamethasone (dex) exposure, pts in the ppx group had numerically greater dex exposure than pts in the no ppx group, with median (range) dosing of 182 mg (10-1386mg) and 100mg (1-4000mg), respectively. Finally, we found no significant differences in PFS or OS based on ppx. Median PFS was 9.6 months in the ppx group vs 13.3 months in the no ppx group (p=0.646) and median OS was 17.2 months in the ppx group vs 34.4 months in the no ppx group (p=0.170). Conclusions: In this large cohort of adult patients with R/R ALL receiving brexu-cel CAR-T therapy, prophylaxis intended to prevent CRS/ICANS was ineffective at reducing CRS/ICANS incidence, time to onset, or overall steroid exposure. Furthermore, PFS and OS were comparable between patients who received prophylaxis and those who did not. In the absence of prospective trials in B-ALL, these data suggest that current strategies of CRS/ICANS prophylaxis has limited benefit.

Abstract Introduction: Epcoritamab (epco) and glofitamab (glofit) are bispecific antibodies (BsAbs) approved for the treatment of patients (pts) with relapsed or refractory (r/r) large B-cell lymphomas (LBCLs). Their use is associated with relatively high response rates, with some patients experiencing prolonged remission. It is unclear whether continuous treatment beyond 12 months for pts in remission is beneficial, as continued immunosuppression may result in additional toxicity. We sought to report the outcomes of pts with prolonged remission and survival following BsAb administration. Methods: We performed a multicenter retrospective study including 21 US centers evaluating pts with r/r LBCLs receiving commercially available epco or glofit between 2023 and 2025. Baseline characteristics and outcomes were extracted from medical records. Efficacy and survival outcomes were assessed by site investigators and included overall response rate (ORR), complete and partial response (CR, PR) rates. Pts who responded to BsAbs and had ≥365 days of follow-up from initiation of BsAb treatment were included in the analysis. Results: As of May 15, 2025, a total of 312 pts with r/r LBCLs were treated with BsAbs (epco n=193, glofit n=119) with a median age of 66 years (interquartile range [IQR] 59-73) at BsAb start. Most were male (64.5%), had advanced stage disease (77.4%) and had ECOG performance status of ≤1 (93.3%) at BsAb start. Of 207 pts who had initiated treatment with BsAb ≥12 months prior to data cutoff, we identified 31 pts (15.0%) who had a response to BsAbs (19 epco, 12 glofit) and were alive without progression at 12-months post-BsAb initiation and included them in this landmark analysis. Of the cohort of 19 pts treated with epco, 6 discontinued due to reasons other than disease progression including CAR-T cell therapy (n=2), secondary malignancy (n=2), allogeneic transplant (n=1), or other reasons (n=1). Thirteen of 19 pts received ≥12 months of epco treatment, and, with a median follow-up of 16 months from the start of BsAb, 12 of 13 pts continued receiving epco beyond 12 months with one pt discontinuing after 12 months (observed for an additional 41 days prior to censoring). Of the cohort of 12 pts treated with glofit, 8 pts were observed after completing all planned therapy and 4 patients underwent allogeneic transplant. Among all 31 BsAb-treated patients alive and in remission at 12 months, at the time of data cutoff, 5 pts (12.9%) had progressed (2 previously treated with epco and 3 with glofit). Three of the 4 pts who underwent allogeneic transplant after prior glofit treatment experienced disease relapse. A total of 24 pts (77.4%) were alive at the time of last follow-up, with the causes of death being disease progression (n=1), secondary malignancy (n=1), infection (n=1), and unknown cause (n=4). Conclusions: In this large cohort of r/r LBCL pts treated with BsAbs monotherapy in the standard of care setting, a relatively small proportion of pts (15%) achieve the 12 month PFS landmark. In the absence of robust evidence for what constitutes best practice, different strategies are employed, including continuation of BsAb, observation as well as consolidation with allogeneic transplant or CAR T-cell therapy. Additional follow-up will be reported to help guide clinical decision making regarding the optimal management strategy for this high risk pt population.

Abstract INTRODUCTION Outcomes for 1st relapse of pediatric B-lymphoblastic leukemia (B-ALL), especially high/intermediate-risk (HR/IR) relapse, remain unacceptably poor. Limited enrollment of this population on cooperative group clinical trials has impeded our ability to study potentially effective regimens. In the current era, patients can access innovative immunotherapies commercially. However, there is no mechanism to capture outcomes for these off-study patients and no comparative effectiveness data to guide treatment selection. METHODS We conducted a multicenter, retrospective study of patients <30 years who initiated 1st relapse therapy at a participating center from 2018-2022 (ReCALL-1 Study). Objectives were to define real-world survival outcomes, compare response rates of reinduction strategies, describe the post-reinduction treatment landscape, and, for patients with HR/IR relapse, assess the comparative effectiveness (CE) of blinatumomab to hematopoietic cell transplant (blina/HCT) v CD19 CAR T cells (CART). For the CE analysis, we emulated an open-label, randomized study of blina/HCT v CART who achieved an M1/M2 marrow at the end of an intensive reinduction (EoRI). Patients were classified by their intended treatment at EoRI. Cox regression models were used to adjust for unbalanced patient and disease features by arms. The primary outcome was overall survival (OS) from EoRI. RESULTS The full cohort included 479 patients from 33 centers (31 US, 2 international). Median time to relapse was 31 months (m); 77% had bone marrow (BM) involvement and 31% central nervous sytem involvement. With a median follow-up of 49m from relapse, 4 year (y) OS, event-free survival (EFS), and non-relapse mortality (NRM) were 64%, 43%, and 13%, respectively. Among patients with very early BM (<18m, n=79), early BM (18-35m, n=76), late BM (≥36m, n=162), and isolated CNS (n=85) relapses, 4y OS/EFS were 29%/20%, 57%/35%, 78%/49%, and 84%/61%, respectively. Only 19% received reinduction therapy on a clinical trial. Among patients with BM disease, R3 reinduction (n=179) and VXLD (n=61) had identical MRD-negative (<0.01%) CR rates of 38% (p=1.00) and equivalent treatment failure (TF; M3 or extramedullary disease) rates: R3, 8% v VXLD 7%, p=0.79. Blina (n=33) and inotuzumab-based (n=21) reinductions achieved MRD-negative CR rates of 39% and 52%, respectively, but higher TF rates of 39% and 24%. Reinduction mortality was 2%: R3, n=5; VXLD, n=3; 3-drug reinduction, n=1. Overall, as part of 1st relapse therapy, 36% received CART (78% commercial product), 44% HCT, 40% blina, and 11% inotuzumab. The emulated trial included 159 patients, 95 on blina/HCT and 64 on CART. Study arms were well matched by demographics, cytogenetics, and relapse sites, but CART patients were more likely to have relapsed <18m from diagnosis (34% v 24%) and have EoRI M2 marrows (31% v 11%), and less likely to have private insurance (36% v 51%). Unadjusted OS was comparable between arms (log rank p=0.18): CART, 60% at 4y; blina/HCT, 71%, as was NRM (10% v 13% at 4y). EFS was lower for CART (p=0.049): 4y EFS 35% v 49% for blina/HCT. After adjustment for unbalanced covariates, the hazard of death was equivalent for CART as compared to blina/HCT (aHR 1.1, 95% CI 0.6-2.1, p=0.67) and EFS became more comparable (aHR 1.3, 95% CI 0.8-2.1, p=0.22). 91% of blina/HCT and 97% of CART received their intended cell therapy; time from EoRI to cell therapy was shorter for CART (67 v 86 days, p<.001). In the CART arm, 34% underwent consolidative HCT; 1/3 were preplanned and 2/3 due to loss of B cell aplasia or NGS-MRD positivity. Of those with a 2nd relapse, CART patients were more likely to be CD19 negative (47% v 10%, p=0.003). CONCLUSION In this multicenter, real-world cohort of children treated for 1st relapse in the immunotherapy era, suboptimal outcomes for early BM relapse persisted, with particularly dismal 4y OS of 29% for relapses <18m after diagnosis. In contrast, survival for late BM and isolated CNS relapses compared favorably to historic data. Only 1 in 5 patients initiated relapse therapy on a clinical trial and although 1st relapse is not an approved indication for commercial CART in pediatrics, 36% received CART. In an emulated trial of post-reinduction blina/HCT v CART, adjusted EFS and OS were comparable, suggesting that CART may be a viable alternative to HCT for select patients. Post hoc analyses will identify whether specific subgroups may benefit more from one strategy.

Abstract Introduction: Brexu-cel is a highly effective treatment for R/R B-ALL, with complete responses achieved in 71% of patients (pts) treated in the pivotal ZUMA-3 trial. Patients with B-ALL with high-risk (HR) genetics are known to have inferior outcomes with chemotherapy, but little is known about the influence of HR ALL genetics on responses to chimeric antigen receptor (CAR)-T in adults. In this study, we assessed the impact of HR ALL genetics on outcomes in a large cohort of adult patients treated with brexu-cel for R/R Philadelphia chromosome (Ph)-negative B-ALL. Methods: Patient characteristics and outcomes were obtained from the Real-World Outcomes Collaborative of CAR-T in Adult ALL (ROCCA) database which includes data from 40 U.S. centers. NCCN guidelines (NCCN Guidelines in Oncology, ALL v2.2025) were used to define HR B-ALL genetics; lack of HR genetics was defined as standard-risk (SR). The primary outcome was event-free survival (EFS), defined as lack of response, disease progression, or death from any cause. Secondary outcomes were overall survival (OS), relapse free survival (RFS) and response rates including complete response (CR), CR incomplete count recovery (CRi), measurable residual disease negative CR (MRD-) by flow or NGS and progressive disease (PD). Multivariable models were adjusted for age, pre-infusion blast percentage, prior allo-HCT, and post CAR-T allo-HCT (modeled as a time-varying covariate). Results: The cohort included 286 pts: 169 with HR and 117 with SR B-ALL. The HR cohort included TP53m (n=24, 14%), KMT2Ar (n=16, 9%), CRLF2r (n=65, 39%) and other HR genetics such as JAK2 and other Ph-like, IKZF1, complex cytogenetics (n=64, 38%). Relative to SR pts, HR pts were more commonly Hispanic (50% vs 28%). HR and SR pts had similar disease burden pre-apheresis (>5% blasts: 58% vs 53%), prior blinatumomab (60% vs 58%), prior inotuzumab (42% vs 46%), and prior allo HCT (27% vs 37%). The presence of CNS disease (11% HR vs 12% SR) and extramedullary disease (EMD, 22% HR vs 29% SR) at apheresis was also similar. CR/CRi was achieved in 90.5% of evaluable HR pts (n=147) and 90.2% of evaluable SR pts (n=102); MRD- rates were also similar between HR and SR pts at 78.9% and 78.2% respectively. In unadjusted analyses, EFS did not significantly differ between HR pts (median 9.6 mos; 1-yr: 46%, 95% CI 38%-54%) and SR pts (median 11.6 mos; 1-yr: 48%, 95% CI 38%- 58%). Median RFS (HR: 12.2 mos, SR: 13.3 mos) and median OS (HR: 22.4 mos, SR: 21.0 mos) were also similar. Multivariable models demonstrated no significant associations between HR B-ALL and EFS (HR 1.09, 95% CI 0.73-1.63), RFS (HR 1.13, 95% CI 0.71-1.80), or OS (HR 0.96, 95% CI 0.62- 1.48) relative to SR ALL. 28% of HR patients and 21% of SR patients underwent consolidative allo-HCT. Among the HR subgroup, CR/CRi rate was lowest in KMT2Ar (71%) relative to TP53m (95%), CRLF2r (95%), and other HR genetics (89%). The median EFS was lowest in KMT2Ar (4.1 mos), followed by TP53m (6.9 mos), CRLF2r (11.6 mos), and other HR (11.1 mos). Median OS was also lowest in KMT2Ar (6.8 mos) vs 22.4 mos in TP53m and not reached in CRLF2r or other HR. PD was highest in KMT2Ar pts (29%), as compared to 11% HR other, 10% SR, and 5% TP53 and CRLF2r. The rate of relapse among those that achieved CR across the groups was similar and ranged between 28% -40%. Rates of CD19 negative relapse were similar between all subgroups (13%-15%), however 21% of KMT2A pts underwent myeloid transformation as compared 0% for TP53 and CRLF2 pts, and 2% among other HR and SR pts. 25% of KMT2Ar patients underwent consolidative allo-HCT as compared to 32% CRLF2 pts, 29% TP53 pts, 25% other HR pts and 21% SR pts. Multivariable models evaluating the different genomic subgroups demonstrated that relative to SR B-ALL, only KMT2Ar was associated with inferior OS (HR 3.17, 95% CI 1.53-6.58, p=0020). No associations were seen between HR subgroups and EFS. Conclusion: To our knowledge, this analysis represents the largest examination of adult B-ALL recipients of CAR-T assessed by genomic risk group. We found that response rates and survival outcomes following brexu-cel were similar among HR and SR B-ALL pts, including pts with TP53m and CRLF2r. However, pts with KMT2Ar had lower response rates and dismal EFS and OS, with higher rates of PD and myeloid transformation at relapse, suggesting that alternative strategies are necessary to improve outcomes for patients with R/R KMT2Ar B-ALL.

Abstract Background: Patients with relapsed or refractory (R/R) peripheral T-cell lymphoma (PTCL) have a poor prognosis with median overall survival of ~3-12 months with current therapies, highlighting an urgent unmet need for novel therapeutics. PTCL is uniquely sensitive to epigenetic modifiers. We have shown that DNMT3 inhibitors like 5-azacytidine have potent immunomodulatory effects, including upregulation of cancer testis antigens, in pre-clinical models of T-cell lymphoma. Similarly, we have shown that pralatrexate (PTX) is potentially synergistic with drugs targeting epigenetic regulation. These data suggest a role for combining the immune checkpoint inhibitor pembrolizumab (pembro) with epigenetic agents in patients with PTCL. Methods: PTCL-002 is a multicenter, multi-arm phase Ib study designed to evaluate the safety and efficacy of pembro in combination with PTX and/or decitabine (DAC) in patients with R/R PTCL and CTCL. The study included three arms: arm A (pembro+PTX), arm B (pembro+PTX+DAC), and arm C (pembro+DAC). All patients received pembro 200 mg by IV infusion every 21 days. Dose selection for DAC and PTX in arms A and C, respectively, was based on a continual reassessment method (CRM) while arm B used a partial order CRM. Primary endpoints included MTD, RP2D, dose-limiting toxicities (DLT) and clinical efficacy as assessed by overall response rate (ORR). Secondary endpoints included progression-free survival, duration of response, and overall survival. Select pharmacokinetic and pharmacodynamic endpoints were also included in order to assess immune modulation and identify potential predictors of response. Results: We enrolled 26 patients, including 9 patients in arm A, 7 in arm B, and 10 in arm C. Median age was 61 (range 27-77) with 13 males and 13 females. Racial demographics were as follows: White 62%, Black 23%, Asian 3%, and Hispanic 1%. Median number of prior treatments was 3 (range 1-6). Histologic subtypes included ATLL (n=1), AITL (n=4), PTCL-NOS (n=10), SS (n=1), MF (n=6), PCALCL (n=1), MEITL (n=1), PCAECTL (n=1), and TFh-PTCL (n=1). Twenty-four of 26 patients received at least one dose of study drug and were evaluable for toxicity. Twenty-one of 26 of patients received at least one full cycle of therapy and were evaluable for response. Reasons for early discontinuation included consent withdrawal (n=1), rapid disease progression during cycle 1 (n=2), adverse event (n=1), and investigator decision (n=1). One DLT was observed each in arms A and B for prolonged grade 3 thrombocytopenia and febrile neutropenia, respectively. Three DLTs were observed in arm C including one patient with grade 3 hyponatremia and rash; one patient with grade 4 thrombocytopenia, neutropenia, and anemia; and one patient with grade 4 neutropenia. There were no treatment related deaths. Based on the observed DLTs, the RP2D for DAC in combination with pembro is 20 mg/m2on days 1-3; the RP2D for PTX in combination with pembro is 30 mg/m2on days 1, 8, and 15; for the triplet combination, the RP2D for DAC is 10 mg/m2given on days 1-5 and the RP2D for PTX is 20 mg/m2given on days 1, 8, and 15. Among 21 evaluable patients, responses were as follows: ORR 19% (4/21), CR 10% (2/21), PR 10% (2/21), and disease control rate (defined as proportion of patients with stable disease or better) 38% (8/21). ORR among evaluable patients in arms A, B, and C were 40% (2/5), 29% (2/7), and 0% (0/9), respectively. Analysis of serum cytokine levels in select patients (4 in Arm A, 4 in Arm B, and 5 in Arm C) revealed significant changes in 5 cytokines when compared to healthy age- and sex-matched controls. Of the 5 cytokines, 3 pro-inflammatory cytokines, TNFα, MIP-3α and IL-10, measured at day 1 pre-treatment were significantly higher in trial patients (p= 0.0001, 0.0008 and 0.003 respectively) than in healthy controls. Trial patients who responded to treatment (PR/CR) in any arms demonstrated a decline in serum levels of TNFα and IL-10 by day 15 of cycle 1, whereas non-responders (PD/SD) showed stable to increased levels of both TNFα and IL-10. Conclusion: We successfully identified the RP2D for DAC and/or PTX in combination with pembro in patients with R/R PTCL and CTCL. We demonstrated that an epigenetic platform incorporating the immune checkpoint inhibitor pembrolizumab is safe in heavily pretreated disease. More work on changes in cytokine profiles is needed before drawing any conclusions on their relationship to response.

Abstract This publication represents the first part of an update to the clinical practice guideline on the diagnosis and management of group A streptococcal (Streptococcus pyogenes or GAS) pharyngitis, developed by the Infectious Diseases Society of America (IDSA). Diagnosis of GAS pharyngitis by clinician judgment alone is unreliable, and unselective testing incurs cost and inconvenience for individuals at low risk of having GAS infection. Clinical scoring systems have been used to quantify the probability of a positive GAS throat culture based on standardized criteria such as the presence of fever; tonsillar enlargement or exudate; tender and enlarged anterior cervical lymph nodes; and the absence of cough. The goal of this article is to determine whether a scoring system should be used to decide which patients should have a diagnostic test performed by rapid antigen detection test, molecular methods, and/or throat culture. We performed a systematic review of randomized and nonrandomized studies that compared the use of a clinical scoring system to clinician judgment alone in predicting the outcome of a throat culture. Evidence from studies in children and adults suggests the diagnostic accuracy of a clinical scoring system is comparable to or slightly higher than clinician judgment alone. However, the studies are limited due to small size, lack of uniformity in outcome measures, and incomplete data. The consensus of the panel is that the balance of benefits and harms favors use of a clinical scoring system as part of the evaluation of patients with sore throat. The principal utility of using a scoring system is to identify patients with low probability of GAS pharyngitis and to reduce unnecessary testing.

Background Contact aspiration remains a frontline approach for mechanical thrombectomy (MT) in acute ischemic stroke (AIS). Early evidence correlates catheter size with procedural efficiency and clinical outcomes. Larger‐bore (LB) aspiration catheters may enhance clot ingestion, increase aspiration force, and facilitate faster and more complete recanalization. However, the transition from standard LB catheters (0.068‐0.072″) to super‐large‐bore (SLB, ≥0.080″) devices has raised questions regarding both safety and clinical benefit. Although the use of SLB catheters is increasing, comparative data on their performance versus LB catheters remain limited. This study aims to evaluate the safety and efficacy of SLB compared with LB catheters including data from a large multicenter international registry. Methods We retrospectively analyzed patients with AIS due to LVO treated at 46 international stroke centers between January 2013 and June 2025. Among eligible patients, propensity score matching (PSM) at a 5:1 ratio was used to balance baseline characteristics between those treated with standard LB catheters and those treated with SLB catheters. Safety endpoints included intraprocedural complications, symptomatic intracranial hemorrhage (sICH), distal embolization, and 90‐day mortality. Efficacy endpoints included functional independence at 90 days (modified Rankin Scale [mRS] 0‐2), successful recanalization (TICI ≥2b), first‐pass effect (TICI ≥2b on the first aspiration attempt), and procedural timing to TICI2b. Results A total of 3,100 patients were included (LB n=3,024; SLB n=67). After PSM (LB n=335; SLB n=67), safety outcomes were comparable between groups in terms of intraprocedural complications occurred (p=0.5), sICH (p>0.9), embolization to new territory (p=0.2), and 90‐day mortality (p>0.9). Efficacy outcomes were similarly consistent for functional independence (mRS 0‐2) (p>0.9), successful recanalization (p>0.9), first‐pass effect (p=0.5), and time to TICI ≥2b (27.6 vs. 24.5 minutes; p=0.9). These findings remained consistent in the subgroup with ICA and M1 occlusions, with no significant differences in safety (intraprocedural complications [p=0.4], sICH [p>0.9], embolization to new territory [p=0.6], or 90‐day mortality [p>0.9], nor in efficacy outcomes (functional independence at 90 days [p>0.9], successful recanalization [p=0.9], first‐pass effect [p=0.6], and time to TICI ≥2b [p=0.9]). Conclusion In this large multicenter analysis, the use of SLB aspiration catheters demonstrated comparable safety and efficacy to standard LB catheters for MT in AIS. Despite theoretical advantages in aspiration dynamics, SLB devices did not confer significant procedural or clinical benefit over LB catheters. These findings suggest that while SLB catheters are a feasible alternative, technical and clinical outcomes remain comparable to LB catheters. Further prospective studies are warranted to clarify potential clinical advantages. image

Background The efficacy of EVOKE therapy, a closed-loop spinal cord stimulation (SCS) system, has been demonstrated in a double-blinded randomized controlled trial (RCT). RCT evidence, however, may not be generalizable to clinical practice, while limitations of real-world evidence may affect its validity. The aim of this study was to evaluate the effectiveness of EVOKE therapy in routine clinical practice employing a rigorous data collection approach. Methods The ECAP study was a prospective, multicenter, single-arm, pragmatic study that enrolled SCS candidates with chronic, intractable trunk and/or limb pain in 22 US investigational sites. PROMIS-29 questionnaire and objective neurophysiological metrics were collected, and minimal clinically important differences (MCIDs) were used to characterize baseline dysfunction and response to EVOKE therapy both at trial end and maximal analgesic effect post-implant visit. Pre-specified subgroup analyses were conducted based on diagnosis. Results EVOKE therapy observed included a dose ratio of 1.3 and neural dose accuracy of 2.8 μV. Improvements of >1 MCID were observed for all domains and improvements of ≥2 MCIDs were observed for six of the seven domains. Improvements observed at trial end were maintained or improved at post-implant visit, with statistically significant improvement in holistic MCID (MD 0.2, 95% CI 0.1 to 0.4, p=0.004), and a significantly greater proportion of patients considered holistic MCID responders (p=0.047). Subgroup analysis by diagnosis showed similar outcomes. Conclusions EVOKE therapy was associated with clinically meaningful improvements in a real-world chronic pain population across different subgroups and disease pathologies, with effects observed at trial end reproduced at post-implant visit.

ABSTRACT The American College of Clinical Pharmacy (ACCP) first described the role and history of the pharmacist as principal investigator (PI) in 2000. An update was published in 2010, citing evidence from NIH and the ClinicalTrials.gov registry that showed an increase in the number of individuals with a Pharm.D. degree engaging in pharmacist‐directed research. The 2025 ACCP Publications Committee was charged with providing an update to the 2010 paper. Key findings include a substantial increase in the total amount of federal funding awarded to schools of pharmacy (SoP) between 2011 and 2023, a modest increase in the number of pharmacists receiving federal grants when comparing 2010 with 2024, and evidence of pharmacist leadership and engagement in Clinical and Translational Science Award networks and service on national grant review panels. It remains challenging, however, to ascertain accurate and reliable data on pharmacists serving in PI roles because of the limitations of currently available data sources. This is especially true for pharmacist PIs who receive non‐federal funding. Future opportunities include a continued emphasis on training programs to prepare pharmacists for PI roles, greater institutional support (e.g., research infrastructure, mentoring programs) for pharmacists serving in PI roles, better promotion of research career tracks to Pharm.D. students and trainees, enhanced efforts at SoP to pursue institutional training grants, and more collaborative efforts across professional organizations to advocate for pharmacist‐scientists. An urgent call to action is necessary to ensure the future growth and success of pharmacist‐directed research.

ABSTRACT Pharmacists play a critical role in optimizing medication use, especially in vulnerable populations such as those with chronic kidney disease (CKD). Despite strong evidence and recent guideline endorsements, many pharmacists continue to rely on the Cockcroft–Gault (C‐G) equation for medication dosing. This opinion paper issues a call to action for the widespread adoption of a race‐free, body surface area–adjusted estimated glomerular filtration rate (eGFR BSAadj ) for medication‐related decision‐making, as endorsed by the 2024 Kidney Disease: Improving Global Outcomes CKD guidelines and the National Kidney Foundation and the American Society of Nephrology Taskforce. Persistent variability in pharmacy practice, institutional protocols, and pharmacy education underscores the need for coordinated change. We urge health systems to integrate eGFR BSAadj into electronic health records and clinical decision support to enhance medication decision‐making; institutions to align protocols with contemporary eGFR‐based prescribing standards; pharmacy educators to contemporize and standardize education on kidney function assessment and medication dosing; and regulatory bodies to update licensure and board examinations. The pharmacy profession must act decisively in order to align with evidence‐based, equitable kidney‐related dosing practices and ensure optimal medication management for all patients.
